Description

Technical Field

[0001] The utility model relates to the technical field of mold application protection, in particular to a wear compensation structure for a pressure head of an aluminum-based silicon carbide plate bending mold. Background Art

[0002] In the prior art, when bending products made of aluminum-based silicon carbide, the aluminum-based silicon carbide material is highly brittle at room temperature and easily cracks during bending, resulting in a low product qualification rate.

[0003] In the above process, the stamping die head needs to be repeatedly in contact with the aluminum-based silicon carbide plate. Frequent action will cause structural wear and tear of the stamping die head. If a new stamping die head is not replaced, it will be difficult to ensure the contact between the two, and the stamping die head may even fail to contact the aluminum-based silicon carbide plate. However, frequent replacement not only affects the bending processing efficiency of the aluminum-based silicon carbide plate, but also makes the replacement operation difficult. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the punching die head of the aluminum-based silicon carbide plate bending die is severely worn and difficult to replace, and to propose an aluminum-based silicon carbide plate bending die punching die wear compensation structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The aluminum-based silicon carbide plate bending die pressure head wear compensation structure includes an upper die and a lower die. The upper die is provided with a punching die for movably contacting the aluminum-based silicon carbide plate. A fixed base is fixedly installed on the upper die, and a booster plate is provided in the upper die to cooperate with the punching die. A shift mechanism for adjusting the punching die is provided between the fixed base and the booster plate.

[0007] Preferably, the punching die head is horizontally mounted in the upper die.

[0008] Preferably, a horizontally arranged guide rail is integrally connected to the upper mold, and the booster plate is horizontally sleeved in the upper mold through the guide rail.

[0009] Preferably, the shift mechanism includes a guide rod integrally connected to the fixed base, and a wedge head plate that movably contacts the boost plate is slidably sleeved on the guide rod, a driving boost rod that movably contacts the wedge head plate is threadedly mounted on the fixed base, and a return spring fixedly connected to the wedge head plate is welded on the upper mold.

[0010] Preferably, the guide rod and the wedge head support plate are both arranged vertically.

[0011] Preferably, a silicone pad is integrally connected to the driving boost rod, and a return spring is sleeved on the guide rod.

[0012] Preferably, the boost plate is provided with a guide through hole for slidingly fitting the wedge head against the plate and an end square cavity, the wedge head against the plate is provided with a driving section, and the end square cavity is provided with a driven section corresponding to the driving section.

[0013] Preferably, the guide through holes and the end square cavity are distributed in sequence from outside to inside, and the guide through holes are vertically connected to the end square cavity.

[0014] Preferably, the driving section is in sliding contact with the driven section.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figures 1-4 The aluminum-based silicon carbide plate bending die pressure head wear compensation structure includes an upper die 1 and a lower die 2. The upper die 1 is provided with a punching die 3 for active contact with the aluminum-based silicon carbide plate. During the bending process, the punching die 3 is repeatedly in contact with the aluminum-based silicon carbide plate. Long-term use will cause wear and consumption of the end structure of the punching die 3, affecting the contact between the two in the later stage.

[0026] A fixed base 4 is fixedly mounted on the upper die 1, and a booster plate 5 is provided in the upper die 1 to match the stamping die 3. A shift mechanism 6 for adjusting the stamping die 3 is provided between the fixed base 4 and the booster plate 5. By driving the booster plate 5 to adjust the position in the horizontal direction, the horizontal position of the stamping die 3 is adjusted to ensure that the worn stamping die 3 can still contact the aluminum-based silicon carbide plate after displacement. For details, please refer to the attached manual. Figure 3 With attached Figure 4 The shift mechanism 6 includes a guide rod 601 integrally connected to the fixed base 4, and a wedge head plate 602 that movably contacts the boost plate 5 is slidably sleeved on the guide rod 601, and a driving boost rod 603 that movably contacts the wedge head plate 602 is threadedly mounted on the fixed base 4, and a reset spring fixedly connected to the wedge head plate 602 is welded on the upper mold 1. Under the action of the reset spring, the wedge head plate 602 can achieve self-reset, and the wedge head plate 602 is convenient to disassemble and assemble.

[0027] To further explain, the boost plate 5 is provided with a guide hole 604 and an end square cavity 605 for sliding the wedge head support plate 602. Under the joint action of the guide rod 601 and the guide hole 604, the wedge head support plate 602 can move back and forth in a straight line in the vertical direction. A driving section 606 is provided on the wedge head support plate 602, and a driven section 607 corresponding to the driving section 606 is provided in the end square cavity 605, so that the extruded boost plate 5 can be displaced in the horizontal direction, thereby adjusting the horizontal position of the stamping die 3 to ensure that the stamping die 3 can always contact the aluminum-based silicon carbide plate.

[0028] The punching die 3 is horizontally mounted in the upper die 1 , and the aluminum-based silicon carbide plate is extruded by the punching die 3 .

[0029] A horizontally arranged guide rail is integrally connected to the upper mold 1, and the boost plate 5 is horizontally inserted into the upper mold 1 through the guide rail. The boost plate 5 can move horizontally along the guide rail when being squeezed by the wedge head plate 602, thereby driving the stamping die 3 to adjust its position.

[0030] The guide rod 601 and the wedge head support plate 602 are both arranged vertically, and under the squeezing action of the driving booster rod 603, the wedge head support plate 602 is caused to move up and down in the vertical direction.

[0031] A silicone pad is integrally connected to the driving boost rod 603, and the return spring is sleeved on the guide rod 601 to guide and limit the return spring.

[0032] The guide through holes 604 and the end square cavity 605 are distributed in sequence from the outside to the inside, and the guide through holes 604 and the end square cavity 605 are vertically connected.

[0033] Please refer to the instruction manual for details Figure 4 The driving section 606 and the driven section 607 are in sliding contact, and the inclination angles of the driving section 606 and the driven section 607 are both 45° to ensure that the downward-moving wedge head plate 602 can always be in contact with the supercharged plate 5.

[0034] It should be noted that the specific model specifications of the upper mold 1 and the lower mold 2 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0035] The functional principle of this utility model can be explained through the following operation modes:

[0036] When it is detected that the punching die 3 is deformed due to wear and cannot make precise contact with the aluminum-based silicon carbide plate, the driving booster rod 603 is screwed in the fixed base 4 so that the driving booster rod 603 presses the wedge head against the plate 602 through the silicone pad;

[0037] The wedge head abutment plate 602 enters the end square cavity 605 along the guide rod 601 and the guide through hole 604, and causes the return spring to be forced to contract;

[0038] The wedge head plate 602 squeezes the boost plate 5 through the driving section 606 and the driven section 607, so that the boost plate 5 moves horizontally along the guide track, thereby driving the stamping die 3 to extend, ensuring that the stamping die 3 can contact the aluminum-based silicon carbide plate.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
