Description

Technical Field

[0001] The utility model relates to the technical field of tricycle production, in particular to a door punching die. Background Art

[0002] Electric tricycles are three-wheeled vehicles that use batteries as power and motors as drive to transport goods or people. Electric tricycles use tubular large-capacity, left and right linings, deep discharge, and traction batteries, which can meet the requirements of long-term continuous discharge. The battery can be used normally for two years without reducing its capacity. Punching is required during the production of electric tricycle doors.

[0003] Announcement No. (CN213530388U) discloses a door punching die for the production of electric tricycles. When the top of the power rod is perpendicular to the top of the workbench, the fixing plate is released, and the spring resets to move the fixing plate forward, so that the power rod is stuck in the inside of the fixing groove, thereby fixing the power rod and fixing the tricycle door. When fixing the power rod, the above-mentioned device requires that the top of the power rod be kept perpendicular to the top of the workbench, but in actual application, it requires multiple debugging to achieve this, which will affect the fixing efficiency of the door and needs to be improved.
