A novel punching die for copper-aluminum bars

Abstract

The invention discloses a novel perforating mold for copper-aluminum bar, comprising a device body and a mold, wherein a support frame is arranged on the upper part of the device body, an air cylinderis arranged in the middle of the top part of the support frame, a groove is arranged at the bottom of the air cylinder, and a return spring is arranged at the bottom of the groove. In this invention,Adopted by motor, Gear, chain, a positioning mechanism composed of a rotating shaft and a first telescopic rod, When the copper and aluminum bars are too long, the position of the taper needs to be adjusted, Control motor rotation, drive the gear to turn, The gear drives the chain to rotate, the chain drives the rotating shaft to rotate, the rotating shaft drives the first telescopic rod to rotate, the first telescopic rod drives the nail cone to rotate to the proper position, the mechanism can accurately move the nail cone to the required position, avoids the inaccurate positioning, causes damage to the copper-aluminum bar, affects the quality of the copper-aluminum bar, and reduces the production cost.

Description

Technical field [0001] The invention relates to the technical field of punching molds, in particular to a new type of punching mold for copper and aluminum bars. Background technique [0002] The punching die for copper and aluminum bars is a tool for punching and marking copper and aluminum bars with a fixed pitch. [0003] The aluminum and copper bars used for the primary connection of power equipment need to be perforated when connecting. The traditional method is to use a crutch to measure the hole distance on site and use a nail cone to mark the perforation. This method is time-consuming and laborious. In addition, workers are prone to injury to their hands when hitting with a hammer. When a hole with a larger radius is required or the nail cone is damaged, it is more troublesome to replace the nail cone. When it is necessary to punch a thick copper and aluminum row, it cannot Stably fix the copper and aluminum bars. Summary of the invention [0004] The purpose of the presen...

Problems solved by technology

[0003] The aluminum bar and copper bar used for the primary connection of power equipment need to be drilled in the connection section. The traditional method is to use a crutch to measure the hole distance on site, and use a nail cone to mark the hole. This method is time-consuming and laborious. Moreover, workers are prone to hand injury when they hit with a hammer. When it is necessary to punch a hole with a larger radius or when the nail cone is damaged, it is troublesome to replace the nail cone. When it is necessary to punch a thicker copper and aluminum row, it cannot Stably fix the copper and aluminum row
