This application claims the benefit of priority from Chinese Patent Application No. CN201910309993.3, filed on Apr. 17, 2019. The content of the aforementioned application, including any intervening amendments thereto, is incorporated herein by reference in its entirety.
The present disclosure relates to the technical field of punch, in particular, to real-time control apparatus for punch.
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. Therefore, it is urgent to develop a real-time control device to solve the defects of the prior art.
In order to overcome the deficiency of the prior art, the present disclosure provides a real-time control apparatus of the punch, which solves the technical problem that the slider can not accurately stop at the bottom dead centre, and improves the precision of the punch and the qualified rate of the stamping products.
The technical proposals of the present disclosure are as follows: real-time control apparatus of a punch includes an upper seat, a middle seat and a base. Its bottom of the upper seat is provided with a lifting seat connecting with an oil cylinder; the upper seat is provided with a driving mechanism, which connects and drives a slider to move towards the base to close to its bottom dead centre of the slider, the oil cylinder is activated, pushing the lifting seat to raise a H distance, thereby lifting the upper seat the H distance. The slider is also raised the H distance so as to compensate the H distance falling due to the inertia of the slider, so that the slider stops at its bottom dead centre.
Preferably, the lifting seat is fixed on the middle seat to support the upper seat.
Preferably, the lifting seat includes a bearing platform on which a groove is provided, the groove is provided with a gasket, the top of the gasket meets the bottom of the upper seat, and a first through hole is provided in the bearing platform. The first through hole is connected with the oil cylinder and the groove.
Preferably, the punch also includes a supporting rod arranged in the base, passing through the middle seat and inserting the upper seat.
Preferably, the supporting rod passes through the lifting seat.
Preferably, its center of the bearing platform is provided with a column hole, the supporting rod passes through the column hole, and the centre of the gasket is provided with a second through hole, the supporting rod is sheathed out of the column hole through the second through hole.
Preferably, its periphery of the gasket is provided with a sealing ring, it is provided with a gap between the gasket and the bearing platform, the sealing ring seals the gap.
Preferably, the lifting seat is provided with a plurality of positioning pins, its top of the middle seat and its bottom of the upper seat are respectively provided with lower holes and upper holes matched with the positioning pins.
Preferably, the lifting seat is provided with 4, respectively fixed at its four corners of its bottom of the upper seat.
Preferably, the supporting rod is four, respectively arranged at its four corners of the base.
The beneficial effect of the present disclosure is: the real-time control apparatus of the punch is provided with a lifting seat at the bottom of the upper seat of the punch, the lifting seat is connected to the oil cylinder. The slider moves toward the base to its bottom dead centre, and the slider will continue to move down a distance under the action of inertia, suppose the distance is H. When the slider is close to the bottom dead centre, the oil cylinder is activated to push the lifting seat upward the H distance, thereby lifting the slider the H distance, thereby compensating the H distance falling due to inertia of the slider, and stopping the slider at the bottom dead centre. The real-time control apparatus of the punch greatly improves the precision of the punch, which is reachable 0.01 mm.
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.

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.
In some embodiments of the present disclosure, the lifting seat 50 is fixed on the middle seat 30 to support the upper seat 10, and the installation of the lifting seat to is convenient.
