Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a stamping and trimming die with a scrap cutter. Background Technology

[0002] Stamping trimming is a metalworking process in which dies are used to cut the edges of a workpiece during stamping to achieve the required shape and dimensional accuracy. Trimming punches and dies are commonly used in the trimming process, and the trimming is achieved through the movement between the upper and lower dies. Trimming produces scrap of varying lengths, and the direction of this scrap's fall is uncontrollable. In typical die structures, the scrap pit length is fixed and cannot accommodate all scrap lengths. If scrap gets stuck on the surface of the scrap pit, it can cause jamming, affecting normal production. To avoid this, long-distance trimming is often divided into two or even three processes, significantly increasing die design costs and creating defects in the tool joint appearance. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a stamping edge trimming die with a waste material cutter. The structure of the edge trimming punch has been modified. A waste material breaking cutter has been added to the original edge trimming punch. A groove has been cut in the center line of the punch, a new breaking cutter has been made, and it has been further fixed to the punch with bolts. The structure is simple, effective and low in cost.

[0004] To achieve the above objectives, a stamping trimming die with a scrap cutter is designed, including a trimming punch and a trimming die. A die frame is provided on one side of the trimming die, and a corresponding trimming punch is provided above the trimming die. The trimming punch is provided with a wire cutting groove, in which a cutting cutter is embedded. A scrap pit is provided between the trimming die and the die frame.

[0005] One side of the cutting blade is a connecting boss that corresponds to the wire cutting groove. A threaded hole is provided in the connecting boss. The cutting blade is threadedly connected to the cutting punch by tightening a screw in the threaded hole.

[0006] The cutting blade has rounded corners on both sides.

[0007] The waste pit is welded with two crossbeams.

[0008] The waste pit beams are equipped with corresponding waste baffles.

[0009] Compared with existing technologies, this invention allows the cutting edge of the waste material to contact the die before the die-cutting device during the die-cutting process. Due to the rigidity of the material, the waste material is cut off by the cutting blade during continuous stamping, reducing the length of the original long waste material to a shorter length. This ensures that the waste material can effectively pass through the waste pit regardless of its state. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of a cutting tool for edge trimming.

[0012] Figure 3 This is a schematic diagram of a trimming die.

[0013] See Figures 1 to 3 101 is the trimming punch, 111 is the wire cutting groove, 201 is the trimming die, 211 is the scrap pit, 221 is the scrap pit crossbeam, 231 is the scrap baffle, 301 is the breaking cutter, 311 is the connecting boss, 312 is the threaded hole, 313 is the rounded corner arc, and 4 is the die frame. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 3 As shown, a die frame 4 is provided on one side of the trimming die 201, and a corresponding trimming punch 101 is provided above the trimming die 201, as follows: Figure 1 As shown, the trimming punch 101 is provided with a wire cutting groove 111, and a cutting cutter 301 is embedded in the wire cutting groove 111. A waste pit 211 is provided between the trimming die 201 and the die frame 4.

[0016] like Figure 2 As shown, one side of the cutting blade 301 is a connecting boss 311 that corresponds to and mates with the wire cutting groove 111. A threaded hole 312 is provided in the connecting boss 311. The cutting blade 301 is threadedly connected to the cutting punch 101 by tightening a screw in the threaded hole 312.

[0017] The cutting blade 301 has rounded arcs 313 on both sides of the blade edge. The rounded arcs 313 can flexibly cut the waste material and prevent the cutting blade 301 from rigidly colliding with the waste material, which would cause the waste material to splash.

[0018] Waste pit 211 is welded with two crossbeams 221.

[0019] The crossbeam 221 of the waste pit is equipped with corresponding waste baffles 231. The waste baffles 231 serve to prevent waste from splashing, and are also the place where waste is most likely to get stuck.

[0020] During die punching, the cutting blade 301 device located below the cutting punch 201 first contacts the scrap material stuck above the scrap baffle 231. Since both the cutting blade 301 and the scrap material have rigidity, during the continued punching process, the scrap material will be cut in two along the position of the cutting blade 301, turning the long scrap material into two relatively short scrap materials, so that the length of the scrap material can pass through the scrap pit. After the scrap material falls off, it can continue to the next production.
