The production line products are piled up to ensure the surface quality of the product and reduce the scrap rate. The steel cover is punched with four side square hole molds.

The technical scheme of the utility model: a steel cover punching die with four side square holes, including an upper die, a wedge block, a binder plate, a lower die, an upper die, a bottom plate, a rubber ejector, and is arranged in the lower die and the upper die The punch, the spring arranged on the punch, the wedge includes an outer wedge and an inner wedge, the lower mold is provided with a lower mold seat and a lower mold fixing plate, and the upper mold is equipped with There is an upper mold slider seat, a guide plate is provided between the lower mold fixing plate and the upper mold slider seat, an upper mold slider seat pad is provided on the lower side of the upper mold slider seat, and the upper mold slider seat An outer oblique wedge baffle is arranged on the pad, and the number of the punches is four, corresponding to the positions of the side holes of the steel cover to be processed respectively.

The utility model designs the structure of the inner and outer oblique wedges. Four punches are used to process the four side holes of the steel cover at the same time, so that the square side holes of the steel cover can be punched and formed at one time. The hole position is easy to ensure, without deflection, and easy to operate. Simple, low labor intensity, high efficiency, prevent product accumulation on the production line, ensure product surface quality, and reduce scrap rate.

Preferably, the rubber ejector includes a rubber head, a rubber plate, a screw and a push rod, the screw passes through the rubber head and the rubber plate and is firmly connected to the center of the bottom plate, and the push rod is arranged on the outer ring of the rubber plate On, the upper end of the ejector rod passes through the bottom plate and bears against the upper die slider cushion.

This structure makes it more convenient and reliable to reset the lower die for preparation, complete the four-hole punching operation of the workpiece in a cycle, and improve the punching efficiency.

Preferably, a mold handle is provided at the center of the top of the upper template, an outer wedge fixing plate is arranged on the lower side of the upper template, an inner wedge fixing plate is arranged on the upper side of the bottom plate, and the upper end of the ejector rod passes through After the bottom plate and the inner inclined wedge block are fixed, the upper die slider cushion is supported.

This structure facilitates the installation and clamping of the mold, and at the same time makes the punching process more stable and reliable, preventing the hole position from shifting.

Preferably, the two sides of the upper mold slider seat pad are provided with outer oblique wedge baffles, and the positions of the outer oblique wedge baffles correspond to the positions of the outer oblique wedge fixing plates.

This structure makes the outer wedge block more stable and reliable when going down, and prevents the hole position from shifting.

Preferably, the punch is a rectangular punch, and the two sides of the spring are respectively provided with a punch fixing part and a demoulding part.

This structure makes the punch more stable and reliable when punching, and also facilitates the stripping of the steel cover.

The working principle of the utility model is that the workpiece (steel cover to be processed) is put into the lower die, the upper die moves downward, and the upper die pressing plate compresses the workpiece. The four outer slanting wedges of the upper die continue to move downward, so that the punching lower die and the outer wall of the workpiece fit together, and the inner slanting wedges move the punch down along the inner slanting wedges during the downward movement of the upper die, so that the punch needles can be punched into the lower die, so that The workpiece and waste are separated, and the upper mold is reset under the drive of the slider of the press, and the workpiece is punched four holes at a time. The lower mold has a rubber ejector to reset the lower mold and complete the four-hole punching operation of the workpiece in a cycle.

The utility model designs the structure of the inner and outer oblique wedges, adopts four punches to process the four side holes of the steel cover at the same time, so that the square side holes of the steel cover can be punched and formed at one time, the hole position is easy to ensure, no deflection, easy to operate Simple, low labor intensity, high efficiency, prevent product accumulation on the production line, ensure product surface quality, and reduce scrap rate.
