Hole flanging reshaping die for lower reinforcing plate of engine cover lock

Abstract

The invention provides a hole flanging reshaping die for a lower reinforcing plate of an engine cover lock. The hole flanging reshaping die can eject the lower reinforcing plate automatically, so that the production efficiency is improved, and the excellent planeness of the upper surface is ensured. The hole flanging reshaping die comprises an upper die plate and a lower die plate, wherein the upper die plate is connected with the lower die plate by a guide pillar and a guide sleeve; the upper die plate is provided with an upper die structure; and the lower die plate is provided with a lower die structure. The hole flanging reshaping die is characterized in that the lower die structure is provided with an ejection structure; the ejection structure comprises an ejection plate, an ejection pin and a compression spring; one end of the ejection pin is fixed to the ejection plate, and the other end of the ejection pin is fixed to the lower die plate; and the ejection pin is provided with the compression spring between the lower die plate and the ejection plate.

Description

technical field [0001] The technical field of the invention is a processing device for a reinforcement plate under a hood lock, and in particular relates to a hole-turning and shaping mold for a reinforcement plate under a hood lock. Background technique [0002] A reinforcement plate under the lock of the hood, the structure of which is shown in Figure 5 , Figure 6 , Figure 7 , its processing needs to go through four processing steps of blanking-forming-punching-flange. It is taken out, which reduces the production efficiency. At the same time, manufacturers have increasingly high requirements for the flatness of the upper surface of the lower reinforcing plate. It is necessary to use a shaping die to flatten it, which increases the production process and increases the production cost. Contents of the invention [0003] In view of the above problems, the present invention provides a hole-reversing and shaping mold for the lower reinforcement plate of the hood lock, w...

[0002] A reinforcement plate under the lock of the engine hood, the structure of which is shown in Figure 5 , Image 6 , Figure 7 , its processing needs to go through four processing steps of blanking-forming-punching-flange. It is taken out, which reduces the production efficiency. At the same time, manufacturers have increasingly high requirements for the flatness of the upper surface of the lower reinforcing plate. It is necessary to use a shaping mold to flatten it, which increases the production process and high production costs.
