[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0030] Embodiment one: the stamping die for commutator sheet machining solves the problem that the angle of the existing high-pressure nozzle cannot be adjusted, which leads to a low cleaning range of the high-pressure nozzle, so that the high-pressure nozzle cannot comprehensively clean the stamping die. The use of the nozzle 4 can improve the cleaning range, and the utility model discloses:
[0031] The upper die 2 is slidably connected to the top of the lower die 1. The nozzle 4 is rotatably connected to the outer end of the lower die 1, and the bottom of the nozzle 4 is connected to an external fan through a hose. The top of the nozzle 4 is connected to the pull rope 5, the top of the pull rope 5 is connected to the outer end of the upper die 2, and the bottom end of the middle of the upper die 2 is connected to the cutter 3.
[0032] REFERENCE Figure 1 andFigure 2 The commutator sheet is placed on the lower die 1, the cutter 3 is moved by the movement of the upper die 2, and the commutator sheet can be processed by the stamping of the cutter 3. The air conveyor can deliver air to the nozzle 4, and the air can be delivered to the cutter 3 through the nozzle 4, so that the impurities adsorbed on the cutter 3 can be cleaned. The movement of the upper die 2 can release the pulling of the pull rope 5, so that the pull rope 5 becomes loose, and the nozzle 4 can be rotated in the opposite direction by gravity. The rotation of the nozzle 4 can clean the impurities adsorbed on the commutator sheet, thereby improving the quality of the commutator sheet stamping. After stamping, the upper die 2 is reset, and the movement of the pull rope 5 is driven by the reset of the upper die 2, so that the movement of the pull rope 5 drives the reset of the nozzle 4. Thus, the nozzle 4 has a wide cleaning range, thereby improving the cleaning effect.
[0033] Embodiment two: a stamping die for processing commutator sheet solves the problem that the existing cutter 3 is inconvenient to replace. The use of the sliding block 6 improves the convenience of replacing the cutter 3, and discloses:
[0034] The outer end of the cutter 3 is connected with the sliding block 6, and the outer end of the sliding block 6 is provided with two groups. The outer ends of the two groups of sliding blocks 6 extend into the inside of the sliding groove 7 to constitute a clamping connection. The sliding groove 7 is opened in the inside of the upper die 2, and the upper die 2 is arranged in an "L" shape.
[0035] Reference Figures 2 to 6 When the cutter 3 needs to be replaced, the cutter 3 is rotated, so that the cutter 3 drives the sliding block 6 to rotate, so that the sliding block 6 can rotate in the inside of the sliding groove 7. After the cutter 3 is rotated to a position, the sliding block 6 can be separated from the clamping of the sliding groove 7. Then the cutter 3 is pulled, so that the cutter 3 drives the sliding block 6 to separate from the sliding groove 7, so that the cutter 3 can be disassembled. By reversing the above operation, the sliding block 6 and the sliding groove 7 can be clamped, so that the cutter 3 can be installed on the upper die 2.
[0036] Embodiment three: a stamping die for processing commutator sheet solves the problem of poor stability of the connection between the sliding block 6 and the sliding groove 7 in embodiment two. The connection between the sliding block 6 and the sliding groove 7 can be improved by the connection between the clamping block 8 and the clamping groove 9, and discloses:

The outer end of the clamping block 8 extends into the inside of the clamping groove 9 to constitute a clamping mechanism. The clamping groove 9 is opened in the inside of the upper die 2. The inside end of the clamping block 8 is connected with the spring 10, and the inside end of the spring 10 is connected in the inside of the sliding block 6. The outer end of the clamping block 8 is arranged in an arc shape and is in close contact with the inside of the sliding groove 7.
[0038] Reference Figures 2 to 6The rotation of the sliding block 6 drives the rotation of the clamping block 8, and then the rotation of the clamping block 8 extrudes the clamping groove 9, so that the clamping block 8 is extruded to slide into the inside of the clamping groove 9, the clamping block 8 is disengaged from the clamping groove 9, and the clamping block 8 is extruded to move, so that the spring 10 is compressed and stressed, the force of the spring 10 drives the clamping block 8 to extend into the inside of the clamping groove 9 to form clamping, and then the stability of the connection between the sliding block 6 and the sliding groove 7 is improved.
[0039] Working principle: when the punch die for commutator sheet processing is used, first, referring to Figure 1 and Figure 2 , the commutator sheet is placed on the lower die 1, the cutter 3 is driven to move by the movement of the upper die 2, and then the commutator sheet is processed by the stamping of the cutter 3, air is delivered to the cutter 3 by the nozzle 4, the upper die 2 is moved to disengage the pulling of the pull rope 5, the pull rope 5 is then relaxed, the nozzle 4 is then rotated to clean the impurities adsorbed on the commutator sheet, and after stamping, the upper die 2 is reset, the upper die 2 drives the pull rope 5 to move, so that the pull rope 5 moves to drive the nozzle 4 to reset, and the nozzle 4 has a wide cleaning range, thereby improving the cleaning effect;
[0040] Referring to Figures 2 to 6 , when the cutter 3 needs to be replaced, the cutter 3 is rotated, the sliding block 6 is then rotated by the rotation of the cutter 3, the sliding block 6 can be disengaged from the clamping of the sliding groove 7 after the cutter 3 is rotated to a position, the cutter 3 is then pulled out, the cutter 3 can be disassembled, and the cutter 3 can be installed on the upper die 2 by reversing the above operation;
[0041] Referring to Figures 2 to 6 , the rotation of the sliding block 6 drives the rotation of the clamping block 8, and then the rotation of the clamping block 8 extrudes the clamping groove 9, the clamping block 8 is disengaged from the clamping groove 9, the force of the spring 10 drives the clamping block 8 to extend into the inside of the clamping groove 9 to form clamping, and then the stability of the connection between the sliding block 6 and the sliding groove 7 is improved.
[0042] The contents not described in detail in the specification belong to the prior art known to those skilled in the art.
[0043] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
