Pneumatic device

Abstract

The invention discloses a pneumatic device used for selectively punching. The pneumatic device comprises an upper die (6), a lower die, a punch head (7) arranged on the upper die (6) and a punching channel arranged between the upper die (6) and the lower die; a controller, a cylinder (1), a punching control part, a punching mechanism and a resetting device connected in turn are arranged in the upper die (6); and the punching mechanism extends along the vertical direction, and the lower surface of the punching mechanism is connected with the punch head (7). The pneumatic device has the advantages of simple process and low price.

Description

technical field [0001] The present invention relates to a pneumatic device, in particular to a pneumatic device for selective stamping dies. Background technique [0002] Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity. Due to the use of precision pneumatic devices, the precision of the workpiece can reach the micron level, and the repeatability is high, and the specifications are consistent, and holes, bosses, etc. can be punched out. Among the steel products in the world, 60% to 70% are plates, most of which are stamped into finished products, such as car bodies, chassis, fuel tanks, radiator fins, boiler drums, container shells, motors, and electrical appliances. Iron core silicon steel sheets, etc. are all stamped, and there are also a large num...

Problems solved by technology

[0003] The products produced by the existing continuous molds all have the same shape and size, but some products often adopt the design of step intervals in order to realize the fully automated production of the next process. Solder joints, stamping solder joints 5 times, so selective stamping has to be used

There are two types of existing molds to achieve selective stamping. One is to use a mechanical ratchet mechanism, which is complex, high processing cost, and extremely inconvenient to assemble and maintain; On the slider, it is similar to the ratchet structure. During the up and down movement of the punch press, the force is transmitted through the upper push rod of the mold. This kind of mechanical structure is expensive and complicated to debug, which is not convenient for popularization and application.
