Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a stepper mold that can cut material strips. Background Technology

[0002] A stepping die, also known as a progressive die, is defined as a die with two or more stations in the feeding direction of a strip of material, completing two or more stamping operations at different stations in one stroke of the press. Progressive dies are a commonly used type of die in sheet metal processing. They can sequentially complete multiple stamping operations at different stations during continuous feeding. This die design allows for different processing at each station as the material advances, thus achieving efficient automated production. To improve production efficiency, stepping dies are generally used in conjunction with strip feed. Errors are inevitable during production. Currently, when an error occurs in a step, the strip feed must be cut off at the feed point, requiring a lengthy time to readjust the machine and reducing production efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a stepping die that can cut off the material strip when an error occurs, which leads to a long time to readjust the machine and reduces production efficiency.

[0005] The upper mold includes an upper template, an upper module connected to the upper template, and a pressure plate connected to the upper template. The upper template is provided with a guide groove, and the end of the upper module away from the upper template extends out of the pressure plate. The pressure plate is provided with a through groove.

[0006] The lower mold, disposed opposite to the upper mold, includes a lower template and a lower module connected to the lower template; and

[0007] A cutting mechanism is installed on the upper mold. The cutting mechanism includes a mounting block, a push-pull rod, a punching block, and an elastic element. The mounting block is fixedly connected to the upper mold plate. The push-pull rod is slidably disposed in the guide groove. The push-pull rod is provided with an upper abutment surface and a lower abutment surface. One end of the punching block abuts against the push-pull rod, and the other end of the punching block extends through the mounting block into the through groove. One end of the elastic element abuts against the punching block, and the other end of the elastic element abuts against the mounting block.

[0008] When the punching block abuts against the upper contact surface, the end of the punching block away from the push-pull rod extends out of the pressure plate through the through groove.

[0009] The aforementioned stepping die capable of cutting material strips allows operators to directly adjust the position of the material strip when a punching error occurs, through the cooperation of the upper die, lower die, and cutting mechanism. The erroneous material strip can be cut off according to the actual situation, enabling debugging without stopping the machine. This reduces the time spent on debugging and effectively improves production efficiency.

The upper template 11 is provided with a guide groove 111. The end of the upper module 12 away from the upper template 11 extends out of the pressure plate 13. The pressure plate 13 is provided with a through groove.

[0038] Please see Figure 2 The upper die 10 also includes a buffer telescopic rod, one end of which is fixedly connected to the upper template 11, and the other end of which abuts against the pressure plate 13. Thus, the pressure plate 13 can press the material strip tightly, effectively preventing material strip displacement and improving stamping accuracy. The lower die 20 includes a lower template 21 and a lower module 22, with the lower module 22 fixedly connected to the lower template 21.

[0039] Please see Figures 3 to 5The cutting mechanism 30 includes a mounting block 31, a push-pull rod 32, a punching block 33, and an elastic element 37. The mounting block 31 is fixedly connected to the upper template 11 and is located between the upper template 11 and the pressure plate 13. The mounting block 31 has a mounting groove. The push-pull rod 32 is slidably disposed in the guide groove 111. The push-pull rod 32 includes a rod portion 321 and a driving portion 322 connecting the rod portion 321. The rod portion 321 is provided with a handle 36. The driving portion 322 is provided with an upper abutment surface 323, a lower abutment surface 324, and a pushing inclined surface 325. The pushing inclined surface 325 is located between the upper abutment surface 323 and the lower abutment surface 324. The punching block 33 includes a punching part 331 and a mounting part 332 connected to the punching part 331. The mounting part 332 abuts against the driving part 322. The end of the punching part 331 away from the mounting part 332 passes through the mounting block 31 and extends into the through groove. The elastic member 37 is disposed in the mounting groove. One end of the elastic member 37 is connected to the bottom of the mounting groove, and the other end of the elastic member 37 abuts against the mounting part 332.

[0040] Please see Figures 3 to 5 The cutting mechanism 30 also includes a fixing block 34 and a fixing screw 35. The rod portion 321 is provided with a positioning screw hole. The fixing block 34 is fixedly mounted on the upper template 11. The fixing block 34 is provided with a fixing hole. The fixing screw 35 passes through the fixing hole and cooperates with the positioning screw hole to fix the push-pull rod 32.

[0041] Please see Figure 1 and Figure 2 The stepping die 100 capable of cutting the strip also includes a guiding mechanism 40, which includes a guide rod 41 and a guide seat 42. The guide rod 41 is fixedly connected to the lower template 21, and the guide seat 42 is fixedly connected to the upper template 11. The guide seat 42 is provided with a guide hole, and the guide rod 41 is inserted into the guide hole, which can effectively improve the stamping accuracy.

[0042] The working principle of the stepper die 100 capable of cutting strip described in this embodiment is as follows: When cutting the strip is required, the operator manually pushes the push-pull rod 32 inward from the outside until the cutting block 33 abuts against the upper contact surface 323, and the end of the cutting block 33 away from the push-pull rod 32 extends out of the pressure plate 13 through the through groove; when cutting the strip is not required, the operator manually pulls the push-pull rod 32 outward from the inside until the cutting block 33 abuts against the lower contact surface 324, and the end of the cutting block 33 away from the push-pull rod 32 extends into the through groove. Thus, when a cutting error occurs, the operator can adjust the strip position and cut the strip with the cutting error according to the actual situation, thereby achieving non-stop debugging, reducing debugging time and improving production efficiency.

[0043] The beneficial effects of this utility model are as follows: the cooperation of the upper die 10, the lower die 20 and the cutting mechanism 30 enables the operator to directly adjust the position of the strip when a punching error occurs, and cut the strip with the punching error according to the actual situation, so as to achieve debugging without stopping the machine, thereby reducing the time spent on debugging and effectively improving production efficiency.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
