Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping dies, in particular to an automatic feeding progressive stamping die. BACKGROUND

[0002] A stamping die is a special process equipment for processing materials into parts in cold stamping processing, which is called a cold stamping die. Stamping is a pressure processing method that separates or plastically deforms materials at room temperature by using a die installed on a press to apply pressure. A progressive stamping die, also known as a progressive die or a continuous die, is a stamping die that completes different processing procedures in sequence through multiple stations in a die set.

[0003] For example, the automatic feeding progressive stamping die of "CN222856466U" includes a lower die seat, a lower die installed above the lower die seat, an upper die seat arranged above the lower die, an upper die installed below the upper die seat, and a cutter fixed to one side of the upper die. When processing, the two ends of the material strip can pass through the inside of the movable seat through the cooperation of the feeding mechanism. The material strip is clamped by the motor-driven clamping piece and is transported by the cylinder. After a certain distance, the clamping piece is moved up and the telescopic rod is retracted. The above-mentioned transportation steps are repeated to stably and continuously push the material strip forward in the die, realize automatic feeding, avoid the discontinuity of manual feeding, improve the production efficiency, and accurately control the length of the material strip transported each time by the cylinder. The position of the material in the die is accurate, and the size accuracy and shape accuracy of the stamped workpiece can be ensured.

[0004] However, in the prior art, the fixing structure of the traditional die mainly adopts bolts, positioning pins and other methods. When disassembling, multiple wrenches or special tools are needed, and the disassembly steps are complicated. Workers may delay production downtime due to bolt thread engagement and positioning pin jamming during operation. In addition, repetitive disassembly and assembly actions may cause operator fatigue, reduce safety, and negatively affect the positioning accuracy and service life of the die, which is difficult to meet the needs of modern high-speed stamping production.
