An Upper Die of Stamping Equipment Based on PLC Control

Abstract

The invention discloses an upper mold of stamping equipment based on PLC control, which relates to the field of automation technology, and includes an upper mold assembly and a positive electrode conductive mechanism. The invention adopts a special structure of the upper mold assembly and the positive electrode conductive mechanism installed therein , can cooperate with the lower mold and the negative electrode conductive mechanism to realize the punching and forming of the bottom plate and the side plate, and at the same time assemble the rib plate between the bottom plate and the side plate, and then energize to fix the three together by resistance welding, reducing the processing The process improves the production efficiency and reduces the equipment cost. The traditional one-piece punch design idea is abandoned. The core mold plays the role of fixing the rib plate and has a large gap with the lower mold cavity, while the centering mechanism The top block only protrudes to the outermost side during stamping and cooperates with the rib to play the role of replacing the stamping of the punch, so that the side plate can achieve the expected shape and make it fit closely with the rib, while when unloading, The top block can be retracted and out of contact with the side plate, significantly reducing the discharge force.

Description

Technical field [0001] The present invention belongs to the automation technology, and more particularly to the upper mold of a PLC-controlled stamping device. Background technique [0002] In the air conditioning system, the heat sink is typically fixed to the interior of the car through a metal, and its material has stainless steel (such as SUS430) and a cold rolled steel sheet. At present, a heat sink holder (material is SUS430), its structure Composition includes a bottom plate, two side plates, and a rib, the bottom plate and the side plate are integral structure and is formed by a U shape in advance, and then welded to the bottom plate and the side plates by argon arc welding. Among them, the thickness of the bottom plate and the side panel is 2-3 mm, and the thickness of the rib is 8-12 mm. [0003] The above processing mode is due to the completion of the product processing, the processing efficiency is low, and the bottom plate and the side panel are in the stamping, and...

Problems solved by technology

[0003] The above-mentioned processing method completes the processing and molding of the product through two independent processes, so the processing efficiency is low, and after the bottom plate and the side plate are stamped, due to the existence of elastic recovery, the angle between the side plate and the bottom plate is often greater than 90 degrees. Therefore, when welding the ribs in the later stage, it is necessary to clamp the side plates inwardly with the clamping tool to fully contact the ribs to complete the welding operation. The equipment cost is high and the efficiency is low.

Not only that, argon arc welding will produce more harmful gases, which is not conducive to the health of the staff
