Description

TECHNICAL FIELD

[0001] The utility model relates to a press machine technical field, concretely is a press machine buffer mechanism. BACKGROUND

[0002] The press machine buffer mechanism is an indispensable common mechanical device in the press machine operation system. Its existence is of great significance, and it is mainly used to reduce or completely eliminate the impact or vibration phenomenon generated by the press machine in the work process.

[0003] The main function of the press machine buffer mechanism is to reduce the impact force and vibration during work by absorbing, dispersing or transferring the impact force. When the impact force generated by the press machine acts on the buffer mechanism, the buffer mechanism absorbs, disperses or transfers the impact force to other parts or directions due to its special structure and material properties. This can greatly reduce the wear and tear between mechanical parts due to direct impact. At the same time, since the impact force and vibration are effectively controlled, the noise generated during equipment operation will also be reduced accordingly, which is very beneficial to improving the working environment. Moreover, effective control of impact and vibration can also improve processing accuracy, because in a stable working environment, molds or tools can more accurately process workpieces, thereby improving workpiece quality.

[0004] However, the current press buffer mechanism has certain limitations. Generally speaking, the existing press buffer mechanism only has basic buffering effect, and there is a significant deficiency in the flexibility of buffering capacity. Specifically, the buffering force is usually fixed, and this fixed buffering force cannot adapt to different working scenarios and working requirements. In actual production processes, different workpiece materials, different processing techniques and different press machine working states may require different buffering capacity and buffering effect. However, the existing press buffer mechanism cannot effectively adjust the buffering capacity and buffering effect, which to some extent limits the application of the press machine in more extensive and complex production requirements.

DETAILED DESCRIPTION

[0016] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0017] Embodiment: please refer to Figure 1 The utility model provides a kind of technical scheme: a buffer mechanism of press machine, including main body 1, the outside of main body 1 is equipped with shell support 2, the upper end of shell support 2 is equipped with hydraulic column 3, the lower of hydraulic column 3 is equipped with stamping plate 4, the lower of stamping plate 4 is equipped with buffer connecting plate 5, the lower of buffer connecting plate 5 is equipped with buffer device 6.

[0018] Among them, buffer device 6 includes hydraulic rod 7, limiting plate 8 is installed on the hydraulic rod 7, the lower of limiting plate 8 is equipped with buffer spring 9, the lower of buffer spring 9 is equipped with hydraulic buffer device 11, piston 10 is installed in the inside of hydraulic buffer device 11, the lower of piston 10 is provided with liquid filling bin 12, the lower of liquid filling bin 12 is equipped with connecting base 13, connecting base 13 is equipped with infusion tube 14 on, the other end of infusion tube 14 is equipped with liquid storage device 15, the lower end of liquid storage device 15 is equipped with regulating valve 16, regulating valve 16 is equipped with liquid storage bin 17 above, the upper of liquid storage bin 17 is equipped with baffle 18, the upper of baffle 18 is equipped with rebound spring 19.

[0019] In the embodiment, the multiple layer buffer structure is composed of hydraulic rod, buffer spring and hydraulic buffer device, the limiting plate on the hydraulic rod, buffer spring and the hydraulic buffer device with piston inside jointly act, form multiple layer buffer system, can cope with different size impact force, effectively protect relevant equipment or structure. The setting of piston in hydraulic buffer device makes the buffer more stable and adjustable, can adapt to different working scenarios.

[0020] The hydraulic column 3 is in the form of double columns, and is connected by a stamping plate 4, and the pressure of the hydraulic column 3 is evenly distributed to the surface, so that the pressure is evenly applied to the buffer connecting plate 5 below.

[0021] In this embodiment, the pressure can be evenly distributed to the buffer connecting plate. The situation of excessive local pressure is avoided, because if the pressure distribution is uneven when the press is working, some local areas will bear excessive pressure, which will cause the buffer connecting plate to be excessively worn in these areas. However, the uniform pressure distribution can reduce such uneven wear, thereby prolonging the service life of the buffer connecting plate. In addition, the uniform pressure distribution also makes the entire buffering process more stable, and the equipment will not shake and other unstable phenomena due to uneven pressure when the press is working, which helps to improve the stability and safety of the equipment operation.

[0022] The buffer device 6 is elastically buffered by the buffer spring 9, and when the buffer connecting plate 5 is downward, the buffer spring 9 will exert a certain counterforce on it to slow down the impact force of the stamping plate 4.

[0023] In this embodiment, the impact force of the stamping plate can be effectively reduced. When the press is performing a stamping operation, the stamping plate will produce a large impact force. If there is no buffering effect of the buffer spring, this impact force will directly act on each component of the equipment, causing the equipment components to be easily damaged. However, the presence of the buffer spring greatly reduces the risk of damage to each component of the equipment due to impact, thereby improving the overall stability and reliability of the equipment, so that the equipment can be stably operated for a long time, reducing the frequency of maintenance and replacement of components.

[0024] The hydraulic buffer device 11 can control the inflow and outflow rate of the hydraulic liquid by adjusting the distance between the adjusting valve 16 and the liquid delivery pipe 14, thereby controlling the hydraulic strength and rebounding force of the hydraulic rod 7.

[0025] In this embodiment, the inflow and outflow rate of the hydraulic liquid can be controlled by adjusting the distance between the adjusting valve and the liquid delivery pipe, thereby realizing the control of the hydraulic strength and rebounding force of the hydraulic rod. In actual production process, different stamping tasks often require different buffering and rebounding effects. For example, for some tasks that require large stamping force but also require fast rebounding speed, the hydraulic buffer device can be adjusted to increase the hydraulic strength and rebounding force; while for some tasks that require a more gentle stamping operation, the hydraulic strength and rebounding force can be correspondingly reduced.

[0026] Working principle: in the actual operation and use situation, when the hydraulic column 3 starts to drive the stamping plate 4 to apply pressure to the lower side, it will first contact the buffer connecting plate 5. This contact process is the beginning of the whole buffer mechanism, and after the buffer connecting plate 5 is subjected to the stamping force applied by the stamping plate 4, it will transfer the stamping force to the hydraulic rod 7.

[0027] After receiving the stamping force, the hydraulic rod 7 will start to move in the downward direction due to the effect of force. In this process, the buffer spring 9 starts to play an important buffering role, which can absorb part of the stamping force applied by the stamping plate 4. At the same time, the limiting plate 8 will apply a counterforce to the pressure change, and the counterforce and the buffering effect of the buffer spring 9 cooperate to adjust the whole pressure system.

[0028] Moreover, at the same time, the working process of the hydraulic buffer device 11 inside also occurs. When the hydraulic rod 7 is pressed down, the piston 10 in the hydraulic buffer device 11 will move. The movement of the piston 10 will squeeze the hydraulic liquid in the liquid filling bin 12 through the liquid conveying pipe 14 to the inside of the liquid storage bin 17. In this process, the adjusting valve 16 can accurately control the flow rate of the hydraulic liquid. Through the control of the flow rate, the hydraulic rod 7 can absorb another part of the stamping force, so as to further improve the buffering function of the whole device.

[0029] When the stamping plate 4 above moves away, the buffer spring 9 will exert its elastic potential to push the hydraulic rod 7 back to the original position. At the same time, the hydraulic liquid in the liquid storage bin 17 will flow back to the liquid filling bin 12 under the elastic action of the return spring 19. And through the effective control of the adjusting valve 16 to the hydraulic liquid backflow process, the buffer connecting plate 5 connected with the hydraulic rod 7 can slowly return to its initial position. Such operation can effectively avoid unnecessary damage to the whole device caused by excessive rebound force, so as to ensure that the device can stably and reliably operate in a long time use process.
