Heat radiation hole punching device of cast aluminum end cover

Abstract

The invention discloses a heat radiation hole punching device of a cast aluminum end cover. The heat radiation hole punching device comprises a base, a lifting plate, a punching head, a containing table and clamp arms. A cam is fixedly mounted on a connecting shaft. A connecting plate is fixedly mounted between fixed plates located on the left side and the right side. An ejection rod is mounted atthe center position of the connecting plate in a sliding manner, and the punching head is fixedly mounted at the lower end of the ejection rod. The interior of the base is of a hollow structure, anda gear is rotationally mounted at the center position in the base through a rotating shaft. The right side of an upper rack and the left side of a lower rack are fixedly connected with the clamp armscorrespondingly. The position of the punching head is changed, and therefore punching work is carried out on cast aluminum end covers of different end face heights, and universality of the device is greatly improved; a drive motor rotates constantly, and therefore the punching head moves up and down to achieve continuous punching on the cast aluminum end cover; and compared with an existing primary punching device, the situation that primary punching is not achieved in place to cause secondary reworking can be effectively avoided, the punching efficiency is greatly improved, and the situationof secondary reworking is avoided.

Description

technical field [0001] The invention relates to the field of casting stamping, in particular to a heat dissipation hole punching device for a cast aluminum end cover. Background technique [0002] The end cover is one of the most widely used mechanical parts and is the main external part of the bearing housing. The general function of the end cover is: axial positioning of the outer ring of the bearing; dustproof and sealing during the working process of the bearing (except for dustproof and sealing itself, it is also often cooperated with the seal to achieve the sealing effect, the material of the motor end cover Generally, they are made of metal, including aluminum, cast aluminum, cold stamped steel, plastic, bakelite, etc. Generally, different materials are selected according to different types of motors. For example, most automobile motors are made of cold stamped steel, and large motors use die-casting technology. . [0003] When producing cast aluminum end caps, it i...

Problems solved by technology

[0003] When producing cast aluminum end caps, it is necessary to punch heat dissipation holes on the end caps. It is difficult to adjust the mold for cast aluminum end caps of different specifications when the existing punching device for heat dissipation holes of cast aluminum end caps punches holes. , and when punching, the end cover cannot be fixed, and deviations are prone to occur
