Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing molds, in particular to a waterproof edge plate bending mold. Background Art

[0002] In the processing process of the existing technology of waterproof edge plates, it is usually necessary to perform a right-angle bending process and a V-shaped bending process on the waterproof edge plates respectively. Usually, in the existing technology, a right-angle bending mold and a V-shaped bending mold are respectively configured for the above two processes. During processing, the waterproof edge plate is first placed on the right-angle bending mold for the right-angle bending process, and then the waterproof edge plate is placed on the V-shaped bending mold for the V-shaped bending process; this requires the waterproof edge plate to be transferred between different molds: after the waterproof edge plate is bent at a right angle by the right-angle bending mold, the waterproof edge plate is transferred from the right-angle bending mold to the V-shaped bending mold for the V-shaped bending process; and the transfer from the right-angle bending mold to the V-shaped bending mold takes up mold change time, which undoubtedly increases the overall bending process time of the waterproof edge plate and reduces the production process efficiency.

[0003] If the same set of molds can be used to bend the waterproof edge plates and complete the right-angle bending process and V-shaped bending process at one time, the mold change time can be saved, the bending process time can be shortened, and the process efficiency can be increased; however, the existing technology currently lacks such a waterproof edge plate bending mold.

The waterproof edge plate bending mold can be used to process the waterproof edge plate, and the right-angle bending process and V-shaped bending process of the waterproof edge plate can be completed at one time.

[0039] Example 1

[0040] like Figure 1 to Figure 3 As shown, this embodiment proposes a waterproof edge plate bending mold, including an upper mold 1 and a lower mold 2, the direction from the upper mold 1 to the lower mold 2 is a first direction, and the upper mold 1 can reciprocate in the first direction; the upper mold 1 is provided with a V-shaped protrusion 3, and the lower mold 2 is provided with a V-shaped groove 4, during the movement of the upper mold 1 along the first direction, the V-shaped protrusion 3 can be inserted into the V-shaped groove 4; the upper mold 1 is provided with a first bending plane 5, and the lower mold 2 is provided with a second bending plane 6, the first bending plane 5 and the second bending plane 6 are parallel to each other, and the extension direction of the first bending plane 5 and the extension direction of the second bending plane 6 are both along the preset direction, and during the movement of the upper mold 1 along the first direction, the first bending plane 5 can approach the second bending plane 6.

[0041] In this embodiment, the first direction is a vertical direction, the second direction and the third direction are both along a horizontal direction, and the second direction and the third direction are perpendicular to each other.

[0042] The shape of the V-shaped groove 4 is specifically as follows: a first plane 7 is set on one side surface of the lower mold 2 facing the upper mold 1, and the V-shaped groove 4 is formed by the first plane 7 being depressed along a first direction, and the V-shaped groove 4 intersects with the first plane 7 to form a first notch 8; the V-shaped groove 4 has a first groove wall 9 and a second groove wall 10, and the contour of the first notch 8 is formed by the edge contour of the first groove wall 9 and the edge contour of the second groove wall 10, and along the first direction, the first groove wall 9 and the second groove wall 10 gradually approach and converge.

[0043] Preferably, along the first direction, a converging end of the first groove wall 9 and a converging end of the second groove wall 10 contact each other.

[0044] Furthermore, the V-shaped groove 4 passes through the lower die 2 along the second direction, so that during the machining process, that is, when the turning tool turns the V-shaped groove in the lower die 2, the turned waste can be cleared from the lower die 2 along the second direction.

[0045] Furthermore, the angle between the first groove wall 9 and the second groove wall 10 can be configured according to specific circumstances. For example, in the present embodiment, the angle between the first groove wall 9 and the second groove wall 10 is 30°±5°.

[0046] Furthermore, the shape of the V-shaped protrusion 3 matches the shape of the V-shaped groove 4 , and the corresponding relationship between the V-shaped protrusion 3 and the V-shaped groove 4 is similar to that between a plug and a socket.

[0047] The first bending plane 5 and the second bending plane 6 are parallel to each other and extend along a preset direction; in the present embodiment, the preset direction is a direction at right angles to the first slot wall 9; it is worth noting that the first bending plane 5 and the second bending plane 6 do not block the first slot 8 at any time.

[0048] like Figure 6-7 As shown, when in use, the upper die 1 is installed at the movable end of the bending machine, and the lower die 2 is installed at the fixed end of the bending machine; the waterproof edge plate is placed on the lower die 2, and the position of the waterproof edge plate is adjusted so that the area to be bent of the waterproof edge plate is located directly below the upper die 1; the bending machine is started, and the upper die 1 moves toward the lower die 2 along the first direction; the V-shaped protrusion 3 first contacts the waterproof edge plate, and the upper die 1 continues to move downward, so that the V-shaped protrusion 3 pushes the waterproof edge plate to deform, and the deformed part of the waterproof edge plate extends into the V-shaped groove 4, and the V-shaped groove 4 plays a role in shaping the waterproof edge plate into a V-shaped bending shape;

[0049] At one moment in the process of the upper mold 1 moving downward, the first bending plane 5 contacts a portion of the upper surface of the waterproof edge plate. In this embodiment, the moment when the first bending plane 5 contacts the waterproof edge plate is after the moment when the V-shaped protrusion 3 contacts the waterproof edge plate. The position where the first bending plane 5 contacts the waterproof edge plate is located at Figure 6-7 The middle V-shaped protrusion 3 is on the left side of the contact position with the waterproof edge plate; the upper mold 1 continues to move downward until the lower surface of the above-mentioned part of the waterproof edge plate contacts the second bending plane 6, and the second bending plane 6 plays a role in shaping the waterproof edge plate at a right angle.

[0050] From the background technology, it can be seen that the technical problem existing in the prior art is the lack of a waterproof edge plate bending mold. Using the waterproof edge plate bending mold to process the waterproof edge plate can complete the right-angle bending process and V-shaped bending process of the waterproof edge plate at one time.

[0051] In this embodiment, the V-shaped protrusion 3 of the upper mold 1 and the V-shaped groove 4 of the lower mold 2 correspond to each other along the first direction, and are used to bend one part of the waterproof edge plate into a V shape; the first bending plane 5 of the upper mold 1 and the second bending plane 6 of the lower mold 2 correspond to each other along the first direction, and are used to bend another part of the waterproof edge plate into a right angle; this embodiment can complete the V-shaped bending process and the right-angle bending process of the waterproof edge plate at one time during the movement of the upper mold 1 toward the lower mold 2; therefore, this embodiment solves the technical problem existing in the prior art: there is a lack of a waterproof edge plate bending mold, and the waterproof edge plate bending mold can be used to process the waterproof edge plate, which can complete the right-angle bending process and the V-shaped bending process of the waterproof edge plate at one time.

[0052] Usually, after the V-shaped bending, a flattening process should be performed at the V-shaped bending, that is, the V-shaped bending is continued to be extruded so that the first groove wall 9 and the second groove wall 10 are parallel to each other or even fit each other. In order to achieve the flattening process, the present embodiment also includes the following technical solutions:

[0053] like Figure 1 to Figure 4 As shown, the waterproof edge plate bending mold also includes a fixed block 11. Along the third direction, the fixed block 11 is arranged on one side of the lower mold 2, and the V-shaped groove 4 is located between the fixed block 11 and the second bending plane 6; along the third direction, the side surface of the fixed block 11 facing the lower mold 2 is the first side surface, and the side surface of the fixed block 11 facing the lower mold 2 is the second side surface; along the third direction, the fixed block 11 and the lower mold 2 are interlocked and connected with each other, and at the same time, the first side surface and the second side surface are configured to be a preset distance.

[0054] Specifically, along the third direction, a receiving groove 12 is provided on the side of the fixed block 11 facing the lower mold 2; along the first direction, a surface of the side of the fixed block 11 facing the upper mold 1 is a second plane 17, the receiving groove 12 intersects with the second plane 17 and forms a second notch 13, and the second side surface is the bottom wall of the receiving groove 12 along the third direction.

[0055] Furthermore, the waterproof edge plate bending mold also includes an upper flat mold 14, which can reciprocate in the first direction; during the reciprocating movement of the upper flat mold 14 along the first direction, the upper flat mold 14 can approach or move away from the second plane 17.

[0056] The preset spacing is configured according to specific circumstances, and is not specifically limited in this embodiment. The preset spacing should be equal to or slightly greater than the thickness of the edge portion of the waterproof edge plate. When the edge portion of the waterproof edge plate is inserted between the first side surface and the second side surface, the first side surface and the second side surface should be able to clamp the edge portion of the waterproof edge plate; Figure 5 As shown, during the flattening process, the upper flat die 14 acts on the waterproof edge plate, and the force exerted by the upper flat die 14 on the waterproof edge plate can be decomposed into an F1 along the third direction and an F2 vertically downward. In this embodiment, the first side surface and the second side surface can clamp the edge portion of the waterproof edge plate to avoid the force exerted by the upper flat die 14 on the waterproof edge plate during the flattening process, causing the waterproof edge plate to separate from the mold along the third direction.

[0057] like Figures 8 to 10 As shown, when in use, the upper flat die 14 is installed at the movable end of the bending machine, and the fixed block 11 is installed at the fixed end of the bending machine; the edge portion of the waterproof edge plate is inserted between the first side surface and the second side surface, and is clamped by the first side surface and the second side surface; the upper flat die 14 approaches the second plane 17, and the lower surface of the upper flat die 14 and the second plane 17 work together to make the V-shaped bent portion on the waterproof edge plate continue to fold until the first groove wall 9 and the second groove wall 10 are parallel to each other, or even fit each other.

[0058] Furthermore, the upper die 1 and the upper flat die 1 can be detachably connected to the movable ends of the bending machine during use to facilitate replacement.

[0059] like Figure 4 As shown, further, the present embodiment also includes the following technical solutions: along the third direction, a side of the fixed block 11 away from the lower mold 2 is provided with a clearance groove 15, and the clearance groove 15 is formed from the side surface of the fixed block 11 away from the lower mold 2 and is recessed toward the direction where the lower mold 2 is located; it also includes a first threaded hole 16, the first threaded hole 16 passes through the fixed block 11 along the third direction, and one end of the threaded hole intersects with the bottom wall of the clearance groove 15; the lower mold 2 is provided with a second threaded hole, and the second threaded hole is coaxial with and communicated with the first threaded hole 16.

[0060] In this embodiment, the fixing block 11 and the lower mold 2 can be fixed by screws. The rod of the screw is screwed into the straight second threaded hole and the first threaded hole 16, and the head of the screw is accommodated in the makeshift groove 15. On the one hand, it makes the overall appearance more beautiful, and on the other hand, it can prevent the head of the screw from protruding too much, which may injure the worker's fingers when the worker replaces the mold or places the waterproof edge plate on the mold.

[0061] The waterproof edge plate bending mold of this embodiment can be used in the bending process of waterproof edge plates used in new energy outdoor battery boxes, outdoor cabinets, and distribution boxes.

[0062] 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.
