Referring to fig. 1-7, there is shown a multi-die punching apparatus comprising a base 1, a die holder 2 provided on the base 1, a plurality of dies 21 arranged in a linear array being arranged on the die holder 2; a plurality of punching devices 3 corresponding to the dies 21 are arranged above the die base 2; the die holder 2 is also provided with a protective fence 5 for preventing the punching operation from being affected by the outside.

Referring to fig. 2 and 3, the plurality of molds 21 are respectively used for erecting workpieces of different types; and, be equipped with first guide rail 11 on the base 1, mould seat 2 moves along first guide rail 11 makes the work piece move the corresponding punching device 3 below. Preferably, a movable cylinder 12 is arranged on the base 1, and the movable cylinder 12 is connected with the die holder 2 in a driving manner.

Specifically, when the multi-die punching equipment is required to process automobile bumpers of different models, a first type of automobile bumper on one die 21 on the die base 2 is punched, after the punching is completed, the moving cylinder 12 controls the die base 2 to move along the first guide rail 11, so that a second type of automobile bumper on the other die 21 moves to the position below the punching devices 3, and the part of the punching devices 3, which is matched with the second type of automobile bumper, works to process the second type of automobile bumper; and so on.

Obviously, the punching devices 3 comprise a plurality of sets of punching devices 3 adapted to a plurality of types of automobile bumpers; that is, assuming that the die base 2 has two sets of dies 21, the punching devices 3 include a punching device adapted to process a first set of dies 21 and a punching device adapted to process a second set of dies 21; it is emphasized here that the displacement cylinder 12 serves to displace the bumper on the die 21 to a position in which it can be machined by the corresponding punching device 3.

Therefore, the punching equipment can be used for processing bumpers of various types, the capital investment requirement on the equipment is reduced, and the floor area of the equipment is saved; and the mould 21 is not required to be assembled and disassembled by workers so as to adapt to bumpers of different types, and the working efficiency is high. The problems that corresponding dies 21 are replaced, the debugging time is long and troublesome, and the production management requirements of modern enterprises are not met are solved.

In addition, most of the existing automobile bumper punching technologies still adopt the phenomenon of oil hydraulic cylinder punching, and the punching in the mode needs a complex control system, has multiple fault points and poor safety. The oil hydraulic cylinder needs to be equipped with a hydraulic system which comprises various control valves of a hydraulic source (an oil pump and an oil tank), and the complex pipelines and the control system cause the increase of fault points, are inconvenient to install, have poor safety and the like. And the oil leakage phenomenon exists, the working environment is polluted, and the production management requirements of modern enterprises are not met.

Therefore, a better punching structure is preferred, and referring to fig. 2 and 4, the punching device 3 comprises an air-hydraulic cylinder 31 fixed on the support frame 4, and a piston rod 311 on the air-hydraulic cylinder 31 is in driving connection with a punching seat; a second guide rail is arranged on the support frame 4, and the stamping seat is driven by the gas-liquid hydraulic cylinder 31 to move along the second guide rail; and the stamping seat is provided with a stamping head 33 for stamping a workpiece.

Specifically, the gas-liquid booster cylinder can achieve high output of the hydraulic cylinder using normal gas pressure, without the need for a hydraulic unit, and is configured to charge the cylinder charge cylinder with an empty oil transfer bribery barrel. The speed is high, and the output is not disordered. The power source is convenient to obtain, and the noise of doing the action is small. The device is simple and easy to adjust and convenient to maintain. The output is large, the high-time output of the oil pressure can be achieved, and the disturbance of the temperature rise of the oil pressure system is avoided. In addition, the punching seat moves along the second guide rail, so that the punching process is more stable, and punching deviation is reduced.

In the above solution, in order to avoid the phenomenon that the piston rod 311 drives the punch holder to generate punch jamming, referring to fig. 4, 5, 6 and 7, the end of the piston rod 311 is a spherical surface, and the end of the piston rod 311 has a clamping edge 312 extending in the circumferential direction; a sleeve 321 is arranged on the stamping seat; the end of the piston rod 311 enters the sleeve 321, and the locking edge 312 is locked and connected with the sleeve 321; the end of the piston rod 311 is in spherical contact with the punch holder 32. In other words, when the piston rod 311 is downward, the end of the spherical surface presses the punching seat, so that the punching head 33 punches a hole for the bumper of the automobile; the end of the spherical surface on the piston rod 311 can enable the end of the spherical surface to still sufficiently press the punching seat even if the downward path of the piston rod 311 is deviated, and the punching seat can still stably punch with the help of the second guide rail; when the piston rod 311 is upward, the locking edge 312 is locked with the sleeve 321, so as to drive the punch holder to ascend.

In the above solution, in order to avoid crushing the surface of the workpiece during punching, referring to fig. 4 and 6, a buffer plate 34 is connected below the punching seat, and a buffer pad 341 for contacting the surface of the workpiece is arranged below the buffer plate 34; the punch 33 penetrates the cushion plate 34 and the cushion 341; the punching seat and the buffer plate 34 are connected through a contour screw (not shown), and a spring 322 is sleeved outside the contour screw. Wherein the buffer 341 is made of polyurethane, preferably, the outer surface of the buffer 341 is adapted to the outer surface of the workpiece. In other words, when the piston rod 311 presses the punch holder, the punch holder descends, and the buffer plate 34 and the buffer pad 341 connected to the punch holder also descend until the buffer pad 341 contacts the outer surface of the workpiece, and the punch holder continues to descend, so that the punch 33 penetrates through the buffer pad 341 and punches the workpiece. In this process, the spring 322 also acts as a buffer. And preferably, the spring 322 is a rectangular spring, and the rectangular spring has stronger bearing capacity and longer service life compared with a common spring.

In the above scheme, referring to fig. 4 and 5, a baffle 35 is disposed on the support frame 4, the baffle 35 is disposed on one side of the second guide rail, a receptacle 351 is disposed on the baffle 35, a plug pin is inserted into the receptacle 351, and the plug pin inserted into the receptacle is located on a moving path of the punch holder 32. Therefore, the bolt can block the stamping seat 32 from moving, and the hidden danger that maintenance personnel are accidentally injured due to the residual air pressure in the air-liquid pressure competing cylinder 31 when maintenance personnel maintain equipment is prevented.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
