Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, in particular to a length-adjustable dovetail pad stamping die. Background Art

[0002] At present, the die structure of dovetail pads is mostly a single structure, because there are many product specifications and the length of dovetail pads varies a lot. Therefore, it is necessary to process many dovetail pads of various specifications to meet production needs, which increases a lot of manpower and material resources, resulting in increased costs.

[0003] To solve the above problems, publication number CN206855613U (stamping die assembly for preparing dovetail gaskets) realizes the ability to punch dovetail gaskets of different lengths and quickly demold them by providing a concave die assembly, a punch die assembly, a positioning mechanism and a unloading mechanism.

[0004] However, when the above patent is used, when punching dovetail pads of different lengths, the tooling personnel are required to manually move the positioning end. During the manual movement, due to the lack of a limiting mechanism, it is difficult to accurately determine the distance of each movement, which can easily lead to the processed dovetail pads being of different lengths, and is not suitable for mass customization. Utility Model Content

[0005] The utility model provides a length-adjustable dovetail pad punching die, which is used to solve the defects in the prior art.

[0006] The utility model is realized through the following technical solutions:

[0008] When the present application is used, the moving limit block is first adjusted to a position according to the scale line, and then locked at the position by a locking device. Then the moving block is manually moved toward the die assembly, and the movement of the moving block drives the movement of the clamping mechanism, and when the first touch unit on the front side of the moving block contacts the limit block, the clamping device is controlled by the controller to clamp the raw material, and then moves backward and when the second touch unit contacts the inner wall of the strip groove, the clamping device is controlled by the controller to unlock, thereby ensuring that the distance the raw material is driven each time is the same, thereby ensuring that the length of the processed dovetail pad remains unchanged, which is suitable for mass processing, and can achieve processing of dovetail pads of different lengths by adjusting the position of the limit block.

[0009] Preferably, the locking device comprises a screw rod vertically connected to the limit block, the strip groove is provided with a through groove along its length direction, the screw rod passes through the through groove and is threadedly connected with a nut, and a fixing plate in contact with the inner wall of the strip groove is fixedly sleeved on the screw rod. The nut can be rotated along the screw rod, so that the strip plate is clamped under the action of the fixing plate to achieve fixation.

[0010] Preferably, the clamping mechanism comprises a return plate, the return plate and the moving block are fixedly connected via a connecting plate, the top surface of the return plate is fixedly connected with an electric telescopic rod passing through the return plate, and the lower end of the electric telescopic rod is vertically connected with a pressing plate. The downward movement of the pressing plate can clamp the raw material in the return plate to achieve clamping.

[0011] As a preferred embodiment, a support block is further included, and the support block and the return plate are located on the same longitudinal line. The support block can play a role in supporting the raw materials.

[0012] Preferably, L-shaped plates are fixedly connected to both sides of the top surface of the support block, and the L-shaped plates and the support block together form a C-shaped structure. The L-shaped plates and the support block together not only play a supporting role, but also play a blocking role to prevent the raw materials from shaking left and right.

[0013] The beneficial effects of the present invention are as follows: by using the present application, the moving distance of the moving block can be changed by adjusting the limit block, and the raw material can be pulled by the first touch unit and the second touch unit, which can ensure that the distance the raw material is driven each time is the same, thereby ensuring that the length of the processed dovetail pad remains unchanged, which is suitable for large-scale processing, and the position of the limit block can be adjusted to achieve the processing of dovetail pads of different lengths.

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A length-adjustable dovetail pad die, such as Figure 1-3 As shown. It comprises a strip plate 1, the strip plate 1 is provided with a strip groove 2 along its length direction, a limit block 3 and a moving block 4 are slidably matched in the strip groove 2, the limit block 3 is located at a side away from the die assembly and is locked by a locking device, the locking device comprises a screw rod 7 vertically connected to the limit block 3, the strip groove 2 is provided with a through groove along its length direction, the screw rod 7 passes through the through groove and is threadedly connected with a nut 8, and a fixed plate 9 in contact with the inner wall of the strip groove 2 is fixedly sleeved on the screw rod 7.

[0022] A clamping mechanism is fixedly arranged on the moving block 4, and the clamping mechanism includes a return plate 10, and the return plate 10 is fixedly connected to the moving block 4 through a connecting plate, and an electric telescopic rod 11 passing through the return plate 10 is fixedly connected to the top surface of the return plate 10, and a pressing plate 12 is vertically connected to the lower end of the electric telescopic rod 11, and the electric telescopic rod 11 is controlled by a controller, and a first touch unit 5 and a second touch unit 6 connected with the controller signal are respectively arranged on the front and rear sides of the moving block 4, and a scale line is engraved on one side of the top surface of the strip plate 1.

[0023] When the present application is used, firstly, the moving limit block 3 is adjusted to the position according to the scale line, and then the nut 8 is rotated. The nut 8 can rotate along the screw rod 7, so that the strip plate 1 is clamped under the action of the fixing plate 9 to fix the limit block 3. Then, the raw material passes between the pressing plate 12 and the return plate 10 and the moving block 4 is manually moved toward the direction of the die assembly. The movement of the moving block 4 drives the movement of the clamping mechanism and when the first touch unit 5 on the front side of the moving block 4 contacts the limit block 3, the electric telescopic rod 11 is extended by the controller, and the extension of the electric telescopic rod 11 drives the pressing plate 12 to move downward, so that the raw material can be clamped in the return plate 10 to achieve clamping. After clamping the raw material, it moves away from the die assembly and when the second touch unit 6 contacts the inner wall of the strip groove 2, the electric telescopic rod 11 is controlled by the controller to retract, wherein the retraction is done after the pressing is completed, thereby ensuring that the distance the raw material is driven each time is the same, thereby ensuring that the length of the processed dovetail pad remains unchanged, which is suitable for mass processing, and by adjusting the position of the limit block 3, dovetail pads of different lengths can be processed.

[0024] The backing plate 10 also includes a support block 13, which is located on the same longitudinal line as the backing plate 10. The support block 13 can play a role in supporting the raw materials.

[0025] L-shaped plates 14 are fixedly connected to both sides of the top surface of the support block, and the L-shaped plates 14 and the support block 13 together form a C-shaped structure. The L-shaped plates 14 and the support block 13 work together not only to support, but also to block, preventing the raw materials from shaking left and right.

[0026] The use of the present application can change the moving distance of the moving block 4 by adjusting the limit block 3, and pull the raw material through the first touch unit 5 and the second touch unit 6, which can ensure that the distance the raw material is driven each time is the same, thereby ensuring that the length of the processed dovetail pad remains unchanged. It is suitable for large-scale processing, and can realize the processing of dovetail pads of different lengths by adjusting the position of the limit block 3.
