TECHNICAL FIELD

[0001] The present application relates to the technical field of forging, in particular to a punch press supporting device. BACKGROUND

[0002] In order to further forge the heated metal piece into the required shape, a punch press is often used to further punch the heated metal piece.

[0003] At present, when the heated metal piece is punched, the metal piece is placed and fixed on the base of the punch press, and then the punch head of the punch press is used to punch the metal piece.

[0004] In the process of implementing the present application, the inventors found that the above-mentioned technology at least has the following problems: the base of the punch press and the punch press are rigidly connected, and the punch head of the punch press generates a large impact force when punching the metal piece, which is easy to damage the punch press in the process of dispersion and conduction. CONTENT OF THE UTILITY MODEL

[0005] In order to facilitate reducing the damage degree of the impact force generated by the punch press to the punch press, the present application provides a punch press supporting device.

[0006] The punch press supporting device provided by the present application adopts the following technical scheme:

[0007] A punch press supporting device, comprising a mounting plate, a base is arranged on the mounting plate, a plurality of limiting cavities are arranged in the base, a plurality of shock-absorbing columns are arranged on the base and extend into the limiting cavities through the top wall of the base, the top ends of the shock-absorbing columns are connected with a shock-absorbing plate for mounting the punch press, a shock-absorbing spring is arranged on the shock-absorbing column and abuts against the shock-absorbing plate and the base, an abutting block is arranged at the bottom end of the shock-absorbing column and abuts against the limiting cavity; a plurality of limiting rods are vertically arranged on the mounting plate and extend through the shock-absorbing plate, and an abutting head is arranged on the top end of each limiting rod and abuts against the shock-absorbing plate.

[0008] By adopting the above technical scheme, the impact force generated by the punch press is conducted to the shock-absorbing plate, and since the shock-absorbing spring is connected between the shock-absorbing plate and the base, part of the impact force can be absorbed by the shock-absorbing spring to prevent excessive impact force from damaging the punch press, in addition, the limiting rods can also limit the shock-absorbing plate to prevent the shock-absorbing plate from shaking when receiving the impact, thereby facilitating improving the stability of the shock-absorbing plate and further reducing the damage degree of the impact force generated by the punch press to the punch press.

[0009] In a specific implementable scheme, a rubber plate is arranged on the shock-absorbing plate, and the shock-absorbing plate is connected with the punch press through the rubber plate.

[0010] By adopting the technical scheme, the impact force generated by the punch press can be absorbed by the rubber plate, so as to reduce the damage degree of the punch press caused by the impact force generated by the punch press.

[0011] In one specific implementation, the punch press support device comprises a base, a plurality of first air cylinders with extendable rods upwardly extending are arranged on the base, and the extendable rods of the plurality of first air cylinders are connected with the mounting plate.

[0012] By adopting the technical scheme, the mounting plate can be driven to move up and down by the air cylinder, so as to conveniently drive the punch press arranged on the mounting plate to move up and down, thereby conveniently adjusting the height of the punch press base for placing the punched part, and further conveniently changing the working height of the punch press to improve the flexibility of the punch press in use.

[0013] In one specific implementation, a plurality of limiting columns vertically arranged and penetrating through the mounting plate are further arranged on the base.

[0014] By adopting the technical scheme, the mounting plate can be limited when moving up and down by the limiting column, so as to improve the stability of the mounting plate when moving up and down, and further improve the stability of the punch press when driven to move by the mounting plate.

[0015] In one specific implementation, the top ends of the plurality of limiting columns are commonly connected with a fixing plate.

[0016] By adopting the technical scheme, the limiting columns can be fixed and the stability of the limiting columns can be improved by connecting a fixing plate at the top ends of the limiting columns.

[0017] In one specific implementation, a plurality of mounting blocks extending out of the base are arranged on the base, a second air cylinder with an extendable rod downwardly extending is arranged on each mounting block, and a support plate is arranged at the bottom end of the extendable rod of each second air cylinder.

[0018] By adopting the technical scheme, before the punching operation, the second air cylinder can be used to extend its extendable rod, so that the support plate is in contact with the ground, thereby conveniently improving the stability of the base during punching.

[0019] In one specific implementation, a rubber pad in contact with the ground is arranged on the bottom wall of each support plate.

[0020] By adopting the technical scheme, the rubber pad is arranged on the bottom wall of the support plate, which not only conveniently reduces the abrasion of the ground on the support plate, but also conveniently absorbs the impact force generated during punching to improve the stability of the punch press during punching.

[0021] In one specific implementation, the punch head of the punch machine is connected with a plurality of limiting wheels on both sides, the fixed plate is provided with a limiting piece, and the limiting piece is provided with a limiting groove for the limiting wheels to extend into and slide.

[0022] By using the above technical solution, when the impact force generated during punching is reacted on the punch head, the punch head will have a tendency to vibrate, and the limiting piece can limit the limiting wheels on the punch head to reduce the damage to the punch machine caused by the vibration of the punch head.

[0023] In one specific implementation, the limiting wheels are provided with rubber wheel pads.

[0024] By using the above technical solution, the rubber wheel pads can absorb the impact force reacted on the punch head during punching, thereby reducing the damage caused by the impact force to the punch machine.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. By installing the shock-absorbing springs between the shock-absorbing plate and the mounting plate, the impact force generated during punching can be absorbed, and by using the limiting rods, the stability of the shock-absorbing plate during punching can be maintained, thereby reducing the damage caused by the impact force generated by the punch machine to the punch machine.

[0027] 2. By extending the telescopic rod of the second cylinder to make the supporting plate adhere to the ground, the stability of the base during punching can be improved.

[0028] 3. By installing rubber wheel pads on the limiting wheels, the impact force reacted on the punch head can be absorbed by the rubber wheel pads, thereby reducing the damage caused by the impact force to the punch machine. BRIEF DESCRIPTION OF DRAWINGS
