Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a multi-station transfer mold negative angle flipping hole interactive wedge mold. Background Technology

[0002] A transfer die, also known as a multi-station echelon transfer stamping die, is an automated stamping die composed of multiple independent stamping stations. A transfer die robot delivers sheet metal workpieces in a queue, station by station, for stamping until a finished sheet metal product is formed. When stamping sheet metal parts, especially when forming flanged holes, the holes are located at the edges, making them prone to burrs and cracks during forming. This affects product quality, requiring subsequent finishing processes, resulting in numerous production steps and low efficiency. Therefore, there is an urgent need to design a multi-station transfer die with negative angle flanging and interactive wedge design to overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, Chinese patent discloses a side-flipping punching station mold for sheet metal products using a transfer mold [application number: 201710628037.2], which includes an upper mold (1) and a lower mold (2). The upper mold used in this invention is provided with an upper template, a left wedge, a right wedge, and a pressure plate. The lower part of the left and right wedges is provided with a wedge push surface and a wedge hook surface. The lower mold is provided with a lower template, a left slider, a right slider, a support block, a left slide frame, and a right slide frame. The right end of the left slider is provided with a flipping punch, and the left end of the right slider is provided with a flipping die. In application, the upper mold and the lower mold are fixed at the corresponding stations of the transfer mold. During operation, the upper mold presses down, and the pressure plate presses the workpiece onto the support block. At the same time, the right wedge moves the right slider to the left, and the left wedge moves the left slider to the right. However, this method is still prone to burrs and cracks when forming edge holes and grooves, which affects the quality of the product. It also requires secondary finishing, resulting in many production steps and low production efficiency. Utility Model Content
