Technical Field

[0001] The utility model relates to the technical field of motor punching sheet progressive dies, in particular to a motor punching sheet progressive die with replaceable stator and rotor punches and concave dies. Background Art

[0002] The progressive die for motor punching is a precise, efficient, multi-station stamping die. It has more than two stations in the feeding direction of the strip material, and completes two or more stamping processes at different stations in one stroke of the press, including blanking, flanging, bending, drawing, three-dimensional forming, etc., to produce the required motor punching.

[0003] The structure of the motor punching progressive die is relatively complex, so its design and manufacturing cycle is also long. At the same time, since it needs to complete multiple stamping processes, the position accuracy requirements for the punch position, die hole position, etc. are also very high. In order to ensure the accuracy and efficiency of stamping, a guide mechanism is usually used.

[0004] In general, the motor punching progressive die is an important tool in the motor manufacturing process, which can efficiently and accurately produce motor punchings that meet the requirements.

[0005] However, the stator and rotor punches and the die structure on the motor punching progressive dies currently on the market are all integrated with the die body, which makes it impossible to disassemble and replace them according to other needs later, and has poor flexibility.

[0006] Therefore, it is necessary to design a motor punching progressive die with replaceable stator and rotor punches and dies to solve the above-mentioned problems. Utility Model Content

[0014] As a preferred solution of the utility model, a plurality of guide sliders are provided on the inner wall of the longer side of the groove, guide rails are fixedly provided on both sides of the longer side of the fixed block, and the fixed block and the groove are slidably connected through the guide sliders and the guide rails.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0028] Specifically, the second locking structure 6 includes punch installation notches 61 opened on both sides of the longer side of the top of the die body 1, and second connecting holes 62 are opened on the stator and rotor punches 2 and the outer ends of the longer sides of the die body 1; the stator and rotor punches 2 are fixedly installed inside the punch installation notches 61 and through the second hand-tightened bolts 63;

[0029] In this embodiment, the stator and rotor punches 2 are placed inside the punch mounting notch 61, and then the second hand-tightening bolt 63 is passed through the second connecting hole 62 to lock and fix the stator and rotor punches 2. When the stator and rotor punches 2 need to be disassembled, the stator and rotor punches 2 can be replaced by directly disassembling them by rotating the second hand-tightening bolt 63 in the opposite direction.

[0030] Specifically, the first locking structure 7 includes a groove 71 opened in the middle of the mold body 1, and the fixed block 5 is integrally embedded and installed in the groove 71; a first connecting hole 72 is opened on one side of the shorter side of the fixed block 5 and the mold body 1, and the fixed block 5 and the mold body 1 are locked and fixed by passing a first hand-tightening bolt 73 through the first connecting hole 72; a plurality of guide sliders 8 are arranged on the inner wall of the longer side of the groove 71, and guide rails 9 are fixedly arranged on both sides of the longer side of the fixed block 5, and the fixed block 5 and the groove 71 are slidably connected through the guide sliders 8 and the guide rails 9;
