After the assembly of the machine was completed, Xu Yi nodded with satisfaction, and returned to his head to re-check the installation drawing.

In any case, the band saw is also an electric machine, and there are high-speed components on it, and only the assembly is absolutely no problem can be turned on. If there are problems or even safety hazards in the installation, booting is a very dangerous thing, and it is easy to damage the machine if it works abnormally, and it may even cause harm to yourself if it is strict.

Xu Yi would rather take a little trouble than risk himself as a guinea pig.

Xu Yi carefully re-checked the machine from top to bottom, from the inside to the outside, and made sure that the installation of the machine was correct, and then he was ready to officially start the machine.

Turn on the power and turn on the switch on the band saw, and you can hear a smooth humming sound from the motor and turn it at high speed.

After carefully observing the pulley of the motor and confirming that the direction of rotation of the motor is correct, Xu Yi cut off the power supply and prepared to process the band saw blade for final assembly.

Xu Yi took apart all the band saw blades that Wang Guangyou gave him, picked out two band saw blades, one thick and one thin, pulled them up and checked them carefully.

The blade of a band saw is different from a disc-shaped circular saw blade, which is made of a long steel belt. The band saw blade is neatly arranged on one side and is polished to a very sharp serration, while the other side remains flat and smooth.

The band saw blade that I just bought has not been welded, and when I use it, I have to intercept different lengths according to different machines, and then align the two ends of the saw blade and weld it, and then polish the welding part to form a ring before subsequent processing.

Xu Yi: These band saw blades were still when Wang Guangyou asked the workers to inspect the machine. helped Xu Yi weld and polish it on the spot. So he also saved a lot of time to do these steps.

But even the blades of a relatively easy-to-use disc saw. Unless otherwise specified, it has to go through some processing procedures before it can be used on the machine, and the band saw blade needs more processing steps before it can be put on the machine.

The most important processing steps are divided into several aspects, on the one hand, to adjust the adaptability of the band saw blade, on the other hand, it is necessary to polish the sawtooth, and then to adjust the cutting work of the saw road.

In the production and welding of the saw blade, because of the punching, grinding will inevitably accumulate a certain amount of internal stress in the saw blade, even if it is annealed when it comes out, it is difficult to ensure that the stress disappears completely, and the saw blade and the saw body of the trailing edge of the saw blade will rise rapidly because of high-speed friction with the wood. If you do not adjust the fitness of the band saw blade. Under the action of thermal expansion and contraction and the internal stress of the saw blade, the originally taut saw edge will gradually become relaxed with the progress of cutting, which will lead to the vibration amplitude of the saw blade to become larger, which will make the saw road wider and the saw road not straight, and the second will also affect the tightness of the combination of the band saw blade and the flywheel, and it may even lead the saw blade to fall off the flywheel or break, thus bringing danger.

Although it is possible to adjust the two flywheels to deflect inward and outward at the appropriate angle during the installation to increase the tension in the middle and rear of the band saw blade and reduce the effects of internal stress and temperature, this is only a stopgap measure. It does not fundamentally solve the problem of stress.

If you want to solve this problem fundamentally, you have to rely on the properties of the saw blade. Various factors such as sawn timber are taken into account for further processing of the saw blade. This has to be done by relying on a roller press to roll different parts of the saw blade with different degrees. By readjusting the stress inside the saw blade through the roll pressure to make it reasonably distributed and adding a certain amount of stress to the saw blade in advance, the problem of the tension of the saw edge falling during the sawing process can be improved.

In order to avoid deformation of the saw blade during the rolling process, this work is carried out on the rolling table in the wood processing plant. However, Xu Yi didn't have a special operating table now, so he simply put the rolling machine on the workbench, and then carried a few wet logs over, sawed them into suitable stakes, and nailed them to the operating table. After drilling holes in these wooden piles, Xu Yi found a few bamboo poles of suitable thickness and cut them into the appropriate length, and nailed them into the holes to make a simple operating table.

After taking out the manual and reading it several times, after comparing the various rolling methods introduced above, Xu Yi decided to adopt the rolling method with the least difficulty in operation. He took the two saw blades to the band saw and hung them to determine the front and back of the two band saws, so as not to process the reverse and waste the saw blades. Back to the edge of the workbench, Xu Yi took a saw blade and passed it through the gap between the rollers of the roller press, and then hung it on the horizontal bamboo poles, overlapped the center line of the roller press wheel with the center line of the long axis of the band saw blade, and then looked at the pressure gauge on the roller press, and rotated the handle on the roller press according to the pressure standard required by the operating procedures, and adjusted the pressure between the rollers to the appropriate level. He then plugged in the power supply to the roller press, which rotated and smoothly pushed the saw blade straight forward.

After the roll was completed, Xu Yi took off the band saw blade and moved it ten millimeters in the direction of the sawtooth, and after reducing some pressure, he repeated the previous process.

This has been repeated, after the front and back sides of the band saw have been rolled several times, Xu Yi took the tension ruler on the front and back sides of the saw blade and checked it against the light.

Seeing that the slight arc formed on the side of the saw blade fit perfectly with the ruler, and the saw teeth and saw back were still straight, Xu Yi breathed a sigh of relief and took off the saw blade, and then hung another saw blade to adjust the number of jù and repeated the previous steps.

Until the saw blade was also processed, Xu Yi turned off the roller press and prepared to break the saw blade.

Xu Yi brought the two band saws to the edge of the workbench, then took a band saw blade to point it up, then took the bayonet on the puller plate with the same width as the band saw blade to jam a sawtooth, and wrenched it hard to the left to make it form a certain angle with the band saw blade, and then jumped over another sawtooth, stuck the front sawtooth, and broke it to the right at the same large angle.

Then skip another sawtooth and break the previous one to the left...... If this is repeated, the sawtooth is pressed on the band saw, pressing the left, center, right, center, left...... The order of the order is regularly arranged.

Although the sawtooth of the two band saws is broken in the same way, the angle formed by the sawtooth and the band saw is different.

The big-toothed band saw was suitable for processing softwood like red pine basswood, so Xu Yi broke the angle of the sawtooth a little wider. As for the thin-toothed band saw, it is more suitable for working hardwood. So Xu Yi also controlled the angle of the sawtooth a little smaller. In order to narrow the saw path and increase the sawing speed of the saw blade.

After the cutting was completed, he checked the sawing path of the two band saws, and after seeing that there was no obvious deviation, Xu Yi stood up and walked towards the tent.

Before going to sleep, Xu Yi couldn't help but sigh softly in his heart. Sure enough, it is completely different whether you have money or not, if you have money, most of these jobs can be done automatically by relying on the machine. I didn't spend that much money, so these jobs. I had to do it all by hand.

It can only be said that fortunately, the sawtooth of these saw blades is ground when it leaves the factory, and I don't need to grind the sawtooth this time. Anyway, the saw blade was finally processed.

After getting up and eating, Xu Yi returned to the edge of the workbench with a band saw, ready for the official test run.

After Xu Yi adjusted the verticality of the two flywheels, he picked up the coarse-toothed saw blade and hung the sawtooth outward directly on the upper and lower flywheels. Adjust the position of the saw blade on the flywheel, expose the front of the band saw to the front edge of the flywheel by 8 mm, and then fix the saw blade with parts such as the guide box and the clamping block.

Once you have made sure that all the fastening devices are in place. Xu Yi adjusted the height of the upper flywheel and adjusted the tension of the band saw blade to the right distance before stopping. Hang several V-belts on the main drive wheel of the band saw and the pulley of the motor.

Xu Yi loosened the fastening screws again, adjusted the position of the belt tension wheel, and after the V-belt tension was appropriate, he pulled the belt by hand to drive the motor and the main transmission wheel to rotate.

While turning the machine, Xu Yi turned his head sideways to watch the movement of the band saw blade on the flywheel, holding his breath and listening carefully to the sound of the machine.

After a few turns in both directions, the saw blade can be hung firmly on the flywheel, without any slippage and sideways, and there is no abnormal sound in the machine.

Xu Yi nodded with satisfaction, turned on the power and then reached out and pressed the power switch, and as the motor rotated, the band saw blade also moved rapidly.

Looking at the phantom conjured up by the fast-moving sawtooth, Xu Yi couldn't help but clench his fist, the operation of this band saw was completely normal!

After the machine ran for a few minutes without any abnormal conditions, Xu Yi turned off the switch and cut off the power supply.

Xu Yi wiped and cleaned the corresponding components again, and then added lubricating oil to the oil filling holes of the conveying components, and then energized again to make the band saw run. To his delight, this time the band saw was turned on not only quieter, but also barely felt any vibration!

Xu Yi picked up a piece of pine wood that was almost a meter long, put the saw blade that was far away from him and aimed at the high-speed movement, and pushed the wood to lean over.

The moment the front edge of the wood touched the saw blade, the humming motor was immediately drowned out by the unusually sharp clanging sound of the saw blade sawing through the wood. I saw that the saw blade cut into the wood very easily, just like cutting into tofu. Even if the saw blade is too new, Xu Yi's speed of pushing the log has slowed down a lot, and it only takes more than a minute for the whole log to be completely sawn.

Xu Yi turned off the switch with satisfaction, and when the machine came to a complete stop, he picked up two pieces of wood, lifted them flat in front of his eyes, squinted his eyes, and hung them off the line, and then the corners of his mouth curled.

The profile of the two pieces of wood is straight, and there is basically no big error.

Of course, the wood is not completely without defects, and the manual breaking of the material will inevitably make the sawing road not as consistent as the angle of the machine, so the sawing surface is inevitably so smooth, and the sawing surface on the two logs has left a series of saw marks of different shades, like a breeze blowing on the surface of the water.

However, Xu Yi had expected this kind of defect, and this kind of defect can be very smooth as long as you push it twice with a planer, or simply put it on a planer.

The last time I made my own beehive, I used a chainsaw to cut the material for efficiency, which not only wasted materials but also wasted time, and it took at least eight or nine minutes to plane a board with a saw belt. However, this is replaced by band saw processing, so that such a thick wood can be easily done in a few minutes, and subsequent processing does not take much time.

Xu Yi couldn't help but sigh to himself, this machine is really better than manpower, this money is not spent in vain......!
