Description

Technical Field

[0001] The utility model relates to the technical field of electronic manufacturing, in particular to a bending tool capable of adjusting a bending position. Background Art

[0002] Bending is a common product feature in metal stamping products. The small bending process steps on some electronic products have strict requirements on the process size.

[0003] like Figure 1-2 As shown, the board used in electronic components has the characteristics of small size, light weight and integration. When processing the board, the protrusions usually need to be bent. After bending, the distance between the upper surface of the board and the bottom surface of the bent protrusion should be H. However, during the production of the board, even the boards of the same batch have slight differences in elasticity and thickness. For example, after two boards with different elasticity are bent, the heights of the rebound of the protrusions of the two boards are different, which will cause the above distance H to be different. For another example, after two boards with different thicknesses are bent, the distance between the upper surface of the board with a larger thickness and the bottom surface of the bent protrusion is greater than that of the board with a smaller thickness. This results in different shapes of the bent boards of the same batch, resulting in unqualified acceptance. Usually in the bending process, By changing the position of the punch and the concave block, that is, the bending position of the plate body, the distance H between different plates can be made consistent; therefore, during the bending process, it is very necessary that the position of the punch and the concave block can be adjusted along the horizontal direction. It is worth noting that during the process of adjusting the position of the punch and the concave block, the spacing between the punch and the concave block should be unchanged, that is, the punch and the concave block should be adjusted synchronously; usually in the prior art, the position of the punch and the concave block along the horizontal direction is adjusted by removing the upper die inner component and the lower die inner component, and then adjusting the position of the upper die inner component and the lower die inner component, and then re-fixing the upper die inner component and the lower die inner component.

[0059] The following is: the upper mold adjustment component 6 adjusts the upper mold inner component 4 so that the upper mold inner component 4 is facing Figure 3 Taking the movement to the designated position in the left direction as an example, the operation and use process of this embodiment is explained.

[0060] When in use, the displacement size of the upper mold component 4 that needs to be adjusted and moved is obtained through calculation, and the first pad 606 that matches the calculation result is selected. The first pad 606 is placed in the gap between the side of the first connecting rod 604 and the bottom wall of the first groove 602, so that one of the side surfaces of the first pad 606 is in contact with the bottom wall of the first groove 602, and the first fastener 605 is rotated to make the first connecting rod 604 move to the left along the second straight line. The first connecting rod 604 drives the upper mold component 4 to move to the left until the first connecting rod 604 is in close contact with the other side surface of the first pad 606, that is, the side surface of the first connecting rod 604 and the bottom wall of the first groove 602 clamp the first pad 606. At this time, the upper mold component 4 is adjusted to the specified position through the upper mold adjustment component 6.

[0061] Then, the above steps are used to adjust the position of the lower die inner component 10 along the second straight line through the lower die adjusting component 12 until it is adjusted into place; at this time, the punch 5 and the concave block 11 also reach the corresponding positions.

[0062] The purpose of such operation is that, due to the very small difference in thickness of the plate or the elasticity of the plate material, the displacement of the upper mold component 4 and the lower mold component 10 along the second straight line is also adjusted within a fraction of a millimeter. In actual use, the adjustment displacement is within 0.5 mm. If the first connecting rod 604 drives the upper mold component 4 to move only by rotating the first fastener 605, on the one hand, there is a lack of a marker to indicate the position to be moved to, and on the other hand, rotating the first fastener 605 easily causes the upper mold component 4 to move excessively. Therefore, in this embodiment, firstly, the first pad 606 corresponding to the displacement to be adjusted is selected, One of the side surfaces of the first cushion block 606 is fitted with the bottom wall of the first groove 602, and then the first connecting rod 604 is driven to move by rotating the first fastener 605 until the other side surface of the first cushion block 606 is fitted with the first connecting rod 604; on the one hand, this indicates that the first connecting rod 604 is moved into place at this time, and the first cushion block 606 is in contact with the first connecting rod 604, which can be regarded as a marker that the first connecting rod 604 has moved to the exact position, that is, the first connecting rod 604 is in contact with the first cushion block 606, which means that the first connecting rod 605 has moved into place, and on the other hand, the first connecting rod 604 is stopped by the blocking effect of the first cushion block 606, which also serves the purpose of avoiding excessive adjustment.

[0063] From the background technology, it can be known that in the prior art, there is a lack of a bending tool with adjustable bending position, which can adjust the position of the punch and the concave block along the horizontal direction without disassembling the upper die components and the lower die components.

[0064] In the present embodiment, a bending tool with adjustable bending position is proposed. The bending tool adds an upper die adjustment component 6 and a lower die adjustment component 12 to the technology of the prior art. The position of the upper die component 4 is adjusted in the horizontal direction by the upper die adjustment component 6, and the position of the lower die component 10 is synchronously adjusted in the horizontal direction by the lower die adjustment component 12. Without disassembling the upper die component and the lower die component, the punch 5 of the upper die component 4 and the recess 11 of the lower die component 10 can be synchronously moved to the specified positions in the horizontal direction. Therefore, the present embodiment solves the technical problem of the lack of a bending tool with adjustable bending position in the prior art. The bending tool with adjustable bending position can adjust the position of the punch and the recess in the horizontal direction without disassembling the upper die component and the lower die component.

[0065] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
