The plate spring is mainly applied to the automobile suspension of the large wheeled vehicle, and has the functions of connecting the frame and the axle together in a suspension mode, exposing between the frame and the axle, bearing the load impact of wheels on the frame, reducing the violent vibration of the vehicle body, and keeping the running stability of the vehicle and the adaptability to different road conditions. The fixing piece is used for fixing the plate spring, is of a U-shaped structure, and is generally formed by punching through a special die and produced in batches.

In the prior art, for example, a chinese utility model patent with publication number CN209049978U discloses a forming device for a U-shaped plate of an axle air suspension bracket, which comprises a female die and a male die for stamping the U-shaped plate and a cylinder body for removing a U-shaped plate product formed by stamping from the female die; the male die is fixedly connected with a punch of the stamping equipment; the female die is connected with the base; the die comprises a first die half and a second die half, a U-shaped groove corresponding to the U-shaped plate is formed in the middle of the die, a positioning groove used for positioning a sample plate is formed in the outer side of the U-shaped groove, an ejection hole communicated with the lower portion of the base is formed in the middle of the U-shaped groove, and a piston rod of the ejection cylinder extends out of the ejection hole into the U-shaped groove. After the female die is matched with the male die to punch the sample plate into a U shape, the piston rod extends out of the ejection hole to eject the product, and then an operator picks up the product and puts the product into the material frame.

The above prior art solutions have the following drawbacks: the forming die is only one group, the working efficiency is low, and the requirement of mass production cannot be met.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a leaf spring mounting stamping forming frock to reach and improve work efficiency, satisfy the effect of mass production demand.

The above object of the present invention can be achieved by the following technical solutions:

the utility model provides a leaf spring mounting stamping forming frock, includes punching press tool, swivel work head and actuating mechanism, punching press tool includes mould and lower mould, it is fixed in on the punching machine drift and is located to go up the mould swivel work head top, with it is provided with at least three to go up mould complex lower mould, around swivel work head turning point evenly distributed on swivel work head, actuating mechanism rotates with swivel work head to be connected, intermittent drive swivel work head rotates.

By adopting the technical scheme, the driving mechanism intermittently drives the rotary workbench to rotate, the upper die is matched with the lower die, the upper die is fixedly connected with the punch of the punching machine, the first sample plate is downwards punched in the first lower die under the action of the punching machine, and the lower die returns after punching is finished; the rotary worktable rotates under the action of the driving mechanism, the second lower die rotates to the position below the upper die, then the rotary worktable stops rotating, the upper die punches the second sample plate downwards again in the second lower die, the second sample plate returns after the punching is completed, the driving mechanism continues to drive the rotary table to rotate, the sequential actions are performed, the punch forming of a plurality of fixing pieces can be automatically and continuously performed, and the working efficiency is greatly improved.

The present invention may be further configured in a preferred embodiment as: the driving mechanism comprises a grooved wheel, a driving plate, a shifting plate and a motor, the grooved wheel is coaxially and fixedly connected with the rotary workbench, the grooved wheel is provided with a sliding groove and an inward concave locking arc which are uniformly distributed, the driving plate is in tangential rotation connection with the inward concave locking arc, the shifting plate is arranged on the driving plate and is in radial sliding connection with the sliding groove along the grooved wheel, and the driving plate is coaxially and fixedly connected with the motor;

the sliding grooves and the concave locking arcs are consistent with the lower die in number.

Through adopting above-mentioned technical scheme, because need have frequency to pause in the swivel work head course of operation, so that the punching machine drives and goes up the mould and carry out the punching press action, if only choose direct drive mechanism such as motor to select for use need often pause restart again, long-time so action can have great damage to the motor, but consequently adopt intermittent type formula driven outer geneva mechanism, if take the initiative driver plate of plectrum to revolve under the motor drive in succession, when the plectrum has not got into the sliding tray of geneva (for avoiding axial force, normally open in radial) in, because indent locking arc on the geneva is blocked by the driver plate, so the geneva is motionless. When the shifting sheet enters the sliding groove, the inward concave locking arc is just loosened, and the shifting sheet drives the grooved wheel to rotate. When the plectrum leaves the sliding tray from the other side, indent locking arc is blocked again, and the sheave stop motion is gone into the sliding tray until next plectrum.
