BACKGROUND

Punch is an advanced basic processing equipment of modern manufacturing industry. According to the type of main drive, it can be divided into mechanical punch and hydraulic punch. It is widely used in the automotive industry, agricultural machinery, household appliances, electronic instruments, national defense industry and daily necessities and other production department.


The punch includes the upper seat, the middle seat and the base. The upper seat is the driving mechanism of the punch machine. the middle seat is provided with a slider, which is a moving part to complete the dynamic action of stamping. The base is a static support structure, the base also contains a fuel tank, which is an important part of the lubrication system.


When stamping, the driving mechanism drives the slider to move down to the bottom dead centre quickly. Due to the role of inertia, the slider can not accurately stop the position of the dead point, and it usually continues to move downward, thus affecting the precision of the stamping product, increasing the reject ratio.


The precision of the bottom dead centre is the most important technical index of the punch, which reflects the manufacturing level of the punch. At the same time, it can affect the precision of the stamping parts and determine the service life of the die.

DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the inventive purpose of the disclosure clearer and clearer, the technical scheme and the technical effect of the disclosure are further explained in combination with the concrete embodiment below. It should be understood that the specific embodiments described herein are intended to explain the disclosure only and not to limit the protection scope of the claim.


Referring to FIG. 1, a common punch includes an upper seat 10 and a base 20 arranged up and down, and a middle seat 30 between the two. The upper seat 10 is provided with a driving mechanism 11. The driving mechanism 11 connects and drives the slider 40 up and down. When the slider 40 moves down to the bottom dead centre, it will continue to move downward a certain distance due to inertia, the distance is recorded as H.


Referring to FIG. 2, its bottom of the upper seat 10 is provided with a lifting seat 50 connected to an oil cylinder (not shown). When the driving mechanism 11 drives the slider 40 to move towards the base 20 to close to the bottom dead centre, the oil cylinder is activated, pushing the lifting seat 50 to raise the H distance, thereby lifting the upper seat 10 upwards by the H distance. The slider 40 is also lifted by the H distance so as to compensate for the H distance falling due to the inertia of the slider 40, so that the slider 40 stops at the bottom dead centre.


It should be understood that the lifting seat 50 should be provided symmetrically at its bottom of the upper seat 10 in order to force the upper seat 10 evenly and lift it smoothly. In some embodiments of the disclosure, the lifting seat 50 is provided with four, respectively, fixed at its bottom quadrangle of the upper seat 10. Thus, the lifting seat 50 can smoothly lift the upper seat 10 to avoid tilting the upper seat 10.
