The store is not only to develop to high precision, but also to the development of automation, in the automatic equipment is inseparable from hydraulic equipment, so the accessories in the hydraulic machine, precision is also a very high product.

The manufacturers of hydraulic presses took the initiative to find some high-precision enterprises in Diankou, and asked for long-term cooperation with them for mutual benefit and win-win results.

You must know that the throttle, especially the hydraulic press, its basic oil pressure is five pascals, that is, five atmospheres, if you encounter a large machine, then its atmospheric pressure, more than five pascals. But eight to ten, the greater the pressure, the higher the requirements of the product, and its precision is self-evident. There is no shortage of transmission arms on automatic lathes, and the transmission arm is driven by the power of hydraulic pressure, and it can only be transmitted to the designated place under the condition that the hydraulic pressure meets the transmission arm, so as to complete a complete set of its own actions. The hydraulic valve and spool are the supply of hydraulic oil, so that the pressure of the hydraulic oil drives the robot to complete a complete set of actions of the robot.

There are three millimeter diameter oil pipes inserted in the throttle core, and there are many such oil pipes inserted in the hydraulic box of the mechanical arm in a robotic hand, and the robot hand is pushed out by the pressure of the hydraulic pump, and the piston ring in the hydraulic box is squeezed out by the thrust of the hydraulic force, forming a powerful force to drive the operation of the robot.

Therefore, the oil pressure has a set of circuits, when the manipulator is sent to the designated place to complete its designated action, another set of reflux oil pressure will push the robot arm back, return to the original position, and move repeatedly.

There are two sets of hydraulic pumps on the hydraulic tank, one is conveying, one is backflow, circulating back and forth in the two oil cylinders, and the shut-off task is implemented through the action of the electronic valve, and the action of the conveying electronic valve is done, the reflux electronic valve will be cut off, the conveying valve is a red light, then the reflux valve is a green light, on the contrary, the conveying valve is a green light, and the reflux valve is a red light. Several oil pipes in the transfer pump convey the oil to the hydraulic piston box of the mechanical arm through the pump pressure, and the piston ring pushes the arm to the designated place through the oil pressure. When the conveying valve is cut off, the return valve is opened, the oil pump absorbs the oil in another set of oil pipes back into the oil cylinder, and the piston ring of the manipulator absorbs back, driving the movable connecting rod to form a circuit and return to the original position.

Therefore, it seems that the small oil pipes are the same as the infusion pipes, but they have magical power, so that the machinery can achieve fully automated production, and the valve core that controls the small oil pipes is the most critical component of the hydraulic press. The valve is a square copper pimple, one end is connected with the mouth of the oil cylinder, one end is connected to the delivery pipe, and the oil cylinder is connected to the internal thread, the tooth is very fine and dense, and the connecting external tooth on the oil cylinder is matched, because the tooth is fine and dense, the embossing and anastomosis is quite high, the artificial production of such a thread, it is almost impossible, can only be achieved with numerical control production. At the place where it meets the pipe, there is a hemispherical arc groove, insert the tube into the arc groove, and then dock an inner tooth with the external tooth kit on the socket to lock the oil pipe. The threads of this product are very thin, the pitch is about 1.5 mm, and the saturation is also very high.

The throttle core is relatively thin, the core column is about the same size as the large ballpoint pen lead, and there are about one millimeter of fine teeth inside, it is set in the outer tooth column, the structure is similar to the valve core, and there is a fine hole like the needle in the middle of the hexagonal head of the stigma, its function is that the air pressure generated by the oil pressure is too large, and the excess air flow must be released, otherwise the air pressure is more and more, and if it cannot be released, then a vacuum will be formed, and the machine will be damaged.

Just such a set of products, a lot of hardware companies are not good, the pass rate is about 35%, the hydraulic plant is selected one by one, to screen the good and bad, it is very difficult to do, and the cost is too high, the cooperative enterprises feel that this product is not cost-effective, and they are not willing to cooperate with each other, because both sides are not satisfied with each other, so they can only change one after another. After years of consideration, they still feel that the store is the hometown of hardware, and the convenience of hardware manufacturing should be very perfect, so they took the initiative to find these products to high-precision enterprises and ask for cooperation.

After 2007, automation was initially formed, and many hydraulic press factories were struggling to find a cooperative enterprise with a hydraulic throttle. They really have no way, some find Yongkang, some find Harbin, some find Shanghai and other authoritative cities, some find satisfactory manufacturers, but because the other party's price is too high, they can only retreat, when the store people see this product, many companies are afraid to take orders, afraid that they will not do well, and will lose their wives and soldiers, the gains outweigh the losses.

The bosses of those hydraulic factories saw that no one was willing to take orders, so they had to find the town government and ask Secretary Mo to find a way for them.

Mo Wenquan received four guests from the hydraulic plant from Shandong in one day, after they explained their intentions, Mo Wenquan looked at the samples they were holding in their hands, played with them for a while, and said to several Shandong merchants with a smile: "Everyone, if I am not mistaken, these products you bring should be the valve on the hydraulic press, and this one has a needle eye, it should be the core of the hydraulic accelerator, right!"

One of the merchants replied with a smile: "Secretary Mo, you are really like a torch, you can see it at a glance, yes, we are from Shandong, is a manufacturer of hydraulic presses, a few of us heard that your store's hardware is doing very well, so we came here, I am from Jinan, surnamed Guan, called Yan Song! These three we met on the road, also opened a hydraulic factory, this tall and mighty guy surnamed Xing, called Taikuan!" He pointed to a guy next to him who was five big and three thick. This is called a strict and loose person, with a medium build, a Chinese face, and a pair of short-sighted eyes, and at first glance he is a highly educated person.

The guy who was five big and three rough hurriedly stretched out his hand to shake hands with Secretary Mo, and said while shaking hands: "Secretary Mo, I have been looking up for a long time, we were introduced by Xing Zijiao, and said that the store would not let us down, so we came······!

"Xing Zijiao, didn't you go to Shenzhen? What, remember our store?" Ma Sicheng didn't know when, walked into Mo Wenquan's office, and asked with a smile.

"Hehe, drink water and don't forget to dig wells, Xing Zijiao came to the store, your store is so good to her, she said that she will never forget it in this life! This is her heart! My surname is Xiao Yixian, I am from Tai'an, Shandong, and I also make hydraulic presses!" This person called Xiao Yixian is single, high-definition and thin, with a horse face, but his eyes are bright.

"Oh, I thought you found it yourself? It turned out that Xing Zijiao introduced it!" At this time, An Youqi also appeared in the office.

"We came to the store to show the products to many factories, they are not willing to make our products, since we came, we can't go back so easily, we believe in Xing Zijiao, so we found the town government, just want to pass you, give us a way! By the way, I have to introduce myself, my surname is Yan, my name is Zifang, I am from Jinan. "This is a man called Yan Zifang, who is big and has a wide face and a big head.

Ma Sicheng and An Youqi looked at the products on the table, and An Youqi couldn't help asking: "Your product should be the conveying pipe valve on the hydraulic press, this product is very demanding, the teeth are very thin, and there shouldn't be many products that are done well, right?"

The four merchants nodded to each other, and then shook hands with the three town leaders and understood each other's identities.

Mo Wenquan said: "You put this product here first, let's go to the CNC center to see, can we make such a small thread knife, if you can get it, then your product we will take orders, if you can't get it, we will also give you an answer within a week!

The four of them looked at each other and said, "Okay, let's wait, I hope to wait for the dawn······
