Description

A spring press machine

technical field

The utility model relates to the field of spring processing equipment, in particular to a spring pressing machine.

Background technique

The strong pressure treatment of the spring is to press the spring until the stress of the material layer exceeds the yield point, so that the surface produces negative residual stress and the core produces positive residual stress. There are two kinds of process methods, one is static strong pressure, the spring is pressed to the required height and parked for 6-48 hours, and then released. This method occupies more process devices and equipment, and occupies a larger space, but its performance is relatively stable, and it is suitable for some small springs. Another method is to press the spring to a specified height at a slower speed (about 1min), and then release it slowly (about 1min) to make the spring plastically deformed. Carry out standing processing at this height subsequently, this method has the same effect as static strong pressure, is applicable to all kinds of large springs.

The Chinese patent application number 201310330756.8 discloses a spring pressing machine, which includes a frame, a workbench is arranged on the frame, and a spring conveying device is arranged on the workbench. The spring conveying device includes a horizontal guide rail and a conveying fixture. One side of the guide rail is provided with a telescopic mechanism for strongly pressing the spring and reciprocatingly moving on the horizontal guide rail; when the spring is placed on the horizontal guide rail, one end of the spring touches the first vertical support plate, and the other end of the cylinder piston rod realizes the movement of the spring. Strong pressure.

The weak point of this patent is: as can be seen from the protective net arranged on the horizontal longitudinal beam, the spring will produce a large rebound force under the strong pressure of the cylinder, and the two ends of the spring are connected to the first vertical supporting plate and the piston rod. The conflicting contact between the two planes cannot fix the spring very well. If the spring cannot be fixed well, the spring will be detached during the pressing process, making it difficult for the pressing machine to press the spring during the pressing process. To the specified length, it affects the production and usage of the spring.

Utility model content

The utility model is further configured as: the detachable connection between the extension block and the interference block.

By adopting the above-mentioned technical scheme and through the detachable connection, the size of the extension block matching the spring is replaced according to the diameter of the spring to be processed, so that the extension block and the inner ring wall of the spring can achieve the effect of conflicting and fixing, so that the strong pressing function Better realize the fixation of springs with different diameters, and improve the scope of application of the strong press.

The utility model is further configured as follows: the detachable connection includes a screw rod arranged on the extension block and threadedly connected with the conflicting block.

By adopting the above technical scheme, when the size of the extension block needs to be replaced, the extension block is screwed out from the conflicting block through screw thread connection, and the extension blocks of different diameters are tightened to the conflicting block to complete the disassembly and assembly of the extension block. replace.

The utility model is further configured as follows: the detachable connection includes a bolt arranged on the extension block and inserted into the conflicting block.

By adopting the above-mentioned technical solution, the extension blocks with different diameters and sizes to be replaced are plugged in and out, so that the extension blocks can be easily replaced.

The utility model is further configured as follows: the detachable connection further includes a magnetic piece disposed on the extension block facing the conflicting block for absorbing the conflicting block.

By adopting the above technical solution, the extension block is broken off from the interference block, and the extension block to be replaced is fixed on the interference block through the adsorption effect of the magnet arranged on the extension block, thereby realizing the replacement of the extension block.

The utility model is further configured as follows: the free end of the extension block is hinged with a support rod in the circumferential direction, and a tension spring for the support rod to deviate outward is connected between the support rod and the extension block.

By adopting the above technical solution, the spring is inserted into the support rod, and the support rod is driven by the elastic force of the tension spring to move toward the inner ring wall of the spring to achieve the force of outward expansion, which plays a role of resisting and fixing the spring , the setting of the support rod can well realize the circumferential fixation of springs of different shapes, and further increase the application range of the strong press.

The utility model is further configured as follows: the support rod includes an inclined section whose one end is hinged with the conflicting block and the other end is inclined outward, and a parallel section connecting the free end of the inclined section and the axial direction of the piston rod of the cylinder. The tension spring is connected between the inclined section and the resisting block.

By adopting the above technical scheme, the tension spring is arranged between the inclined section and the conflicting block, providing the tension spring with a space to move, so that the spring will not directly contact the tension spring when it is sleeved into the tension spring, so that The extension spring will not be subjected to external force, which protects the extension spring.

The utility model is further configured as follows: the conflicting block is provided with a groove for inserting one end of the spring.

By adopting the above technical solution, one end of the spring is inserted into the groove of the conflicting block, and the fixing force acting on the circumferential direction of the spring is further increased through the inner surface of the groove, so as to improve the fixing effect of the spring during the strong pressing process.

To sum up, the utility model has the following beneficial effects: one end of the spring is embedded in the limiting groove, which exerts a circumferential fixing force on the spring, so that the spring will not be separated from the press during processing; The setting of the block further increases the contact area between the spring and the extension block, increasing the fixing force on the processed spring; the extension block and the conflicting block are detachably connected to change the size of the extension block to adapt to different types of springs, increasing the strength The scope of application of the press: the support rod exerts a fixing force on the inner ring wall of the spring to expand outwards, realizes the fixing of springs of different shapes, and further enhances the application scope of the press.
