[0002] The precision hot forming stamping process for steel is a processing method that combines hot working and forming processes. First, the steel is heated to improve its plasticity and deformation properties, and then it is formed using a punch and a die. This process can be used to produce highly precise parts with high strength and complex shapes.

[0003] In the precision hot forming stamping process of steel, it is very important to use a reliable positioning structure. However, most of the current positioning structures have a single function, which limits their practicality. In order to improve the efficiency of steel processing, some companies are developing multifunctional positioning structures that can adapt to steels of different shapes and specifications to meet diverse processing requirements. In addition, during the continuous stamping process, steel is prone to adhesion to the mold, which brings inconvenience to the handling and cleaning work.

[0030] Working principle: According to Figure 1 As shown, firstly, the lower die 4 of the required shape and specification is installed above the base 2, and the upper die 7 is installed on the punch press frame 1, so as to perform stamping work on the workpiece, transfer the hot workpiece to the lower die 4, and position it through the positioning rod 502. When the upper die 7 is started to move downward, the trigger rod 801 is driven to squeeze the end of the trigger sliding block 505 to move above the workpiece in the fixed cylinder 503 for limiting. Due to the arc-shaped design of the opening sliding rod 509 at the inner end of the fixed cylinder 503, the sliding block 505 will not be restricted during movement in this direction, but will be restricted in the opposite direction. The first return spring 504 between the moving block 505 and the inner wall of the fixed cylinder 503 is compressed, and at the same time, the trigger rod 801 pushes the push plate 514 downward to move toward the groove 501, and the push spring 513 is compressed, pushing the block 518 connected to the lower end of the push plate 514 into the engaging groove 515, and the arc surface of the block 518 contacts the arc surface of the engaging rod 516, squeezing the engaging rod 516 to move in the engaging groove 515. When the block 518 is inserted into the engaging groove 515, the right-angled surface of the block 518 and the engaging rod 516 contacts and is fixed, thereby limiting the push plate 514.

[0031] When the stamping is completed, the upper die 7 moves up, and the second spring telescopic rod 904 is squeezed and triggered by the trigger block 802, so that the second spring telescopic rod 904 is compressed, and the rope 903 is loosened and separated from the restraint on the first spring telescopic rod 901, and the first spring telescopic rod 901 pushes the first reset plate 902 to reset, and the end of the first reset plate 902 squeezes and triggers the cross bar 511 and the locking rod 516. First, the telescopic rod on the first reset plate 902 contacts the locking rod 516, so that the locking rod 516 moves in the locking groove 515, and the locking spring 517 is compressed, and the locking rod 516 is separated from the locking block 518. The push-out spring 513 pushes the push plate 514 to move up, and the workpiece processed on the lower die 4 is ejected, and the sliding block 505 is located on the workpiece. The first reset spring 504 will drive the sliding block 505 to reset, and the sliding block 505 will be separated from the limit on the top of the workpiece, which is convenient for the subsequent robot arm to pick up the workpiece.
