Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing, and particularly relates to a movable block shaping mechanism. Background Art

[0002] Automobile parts refer to various components and accessories that make up an entire automobile. They interact with each other to ensure that the automobile has normal functions and performance. Automobile parts cover multiple systems, including power transmission, control, braking, safety, electronics, and structure. The design, manufacturing, and assembly of these parts directly affect the performance, reliability, and comfort of the automobile and are a core part of the automobile industry. During the production and maintenance of automobiles, the quality, fitting accuracy, and functional matching of parts are crucial.

[0003] During the debugging of automobile part molds, the problem of part springback is usually encountered, and solving part springback is a very cumbersome task. Especially when the part flanging is ≤ 90°, it is very difficult to achieve the expected effect with traditional shaping mechanisms. When the part flanging is ≤ 90°, the springback must be outward, so inward retraction is required for springback compensation. At the same time, when retracting inward, the shaping punch will surely generate a negative angle (commonly known as: undercut), and traditional punches cannot solve the springback of this type of part. Therefore, a movable block shaping mechanism is proposed to solve the above problems. Content of the Utility Model

[0004] In view of one or more of the above defects or improvement requirements in the prior art, the utility model provides a movable block shaping mechanism, which has the advantages of solving the springback problem of ≤ 90°, improving shaping efficiency and accuracy, strong adaptability, and improving production efficiency.

[0005] To achieve the above object, the utility model provides a movable block shaping mechanism, which includes an upper cover plate, a process strip, a movable block, a backrest, and a shaping lower die;

[0006] A mounting groove is provided in the middle of the lower end of the upper cover plate, and a rotating mechanism is assembled in the mounting groove. The movable block is assembled at one end of the rotating mechanism and is located in the mounting groove at the lower end of the upper cover plate;

[0007] First and second pressing blocks are respectively assembled on two opposite sides of the upper cover plate;

[0008] The backrest is located below the upper cover plate, and a wear-resistant plate is assembled on one side of the backrest;

[0009] The shaping lower die is located on the opposite side of the backrest, and the movable block is located between the backrest and the shaping lower die.

[0010] As a further improvement of the utility model, the wear-resistant plate is inclined, and a graphite coating is provided on the surface of the wear-resistant plate.

[0011] As a further improvement of the present utility model, inclined surfaces are provided on both sides of the inner wall of the installation groove at the lower end of the upper cover plate.

[0012] As a further improvement of the present utility model, inclined surfaces are provided on both sides at the lower end of the movable swing block.

[0013] As a further improvement of the present utility model, an inclined surface is provided on one side at the upper end of the shaping lower die.

[0014] As a further improvement of the present utility model, the wear-resistant plate and the backrest are detachably connected by bolts.

[0015] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present utility model include:

[0016] In the movable swing block shaping mechanism of the present utility model, when the movable swing block drives downward to shape one side of the process strip, the arranged rotating mechanism can drive the movable swing block to rotate slightly left and right. The arranged wear-resistant plate cooperates with the shaping lower die to limit the position during stamping processing, avoiding the deviation of the movable swing block due to contact with the process strip, effectively dealing with the springback problem when the part flanging ≤ 90°, improving the processing accuracy. At the same time, the contact distance between the movable swing block and the process strip can be changed only by adding a gasket on the back side of the wear-resistant plate, and the springback adjustment is convenient. The movable swing block with slight left and right rotation can flexibly adapt to different parts and be adjusted according to the actual situation, so as to ensure the shaping effect. This device reduces the secondary shaping operation caused by springback by quickly and effectively processing parts, thereby improving the overall working efficiency and the production speed of products.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] As shown by Figures 1-4 the movable swing block shaping mechanism includes an upper cover plate 1, a process strip 2, a movable swing block 3, a backrest 4, and a shaping lower die 5.

[0025] A mounting groove is provided in the middle of the lower end of the upper cover plate 1, and a rotating mechanism 11 is assembled in the mounting groove. The movable swing block 3 is assembled at one end of the rotating mechanism 11 and the movable swing block 3 is located in the mounting groove at the lower end of the upper cover plate 1.

[0026] A first pressing block 12 and a second pressing block 13 are respectively assembled on opposite sides of the upper cover plate 1.

[0027] The backrest 4 is located below the upper cover plate 1, and a wear-resistant plate 41 is assembled on one side of the backrest 4.

[0028] The shaping lower die 5 is located on the opposite side of the backrest 4, and the movable swing block 3 is located between the backrest 4 and the shaping lower die 5.

[0029] In this embodiment, when the movable swing block 3 drives downward to shape one side of the process strip 2, the provided rotating mechanism 11 can drive the movable swing block 3 to perform a small amount of left and right rotation. The provided wear-resistant plate 41 cooperates with the shaping lower die 5 to perform position limitation during stamping processing, avoiding the deviation of the movable swing block 3 due to contact with the process strip 2, effectively dealing with the springback problem when the part flanging is ≤ 90°, improving the processing accuracy. At the same time, only by adding a gasket on the back side of the wear-resistant plate 41 can the contact distance between the movable swing block 3 and the process strip 2 be changed, and the springback can be adjusted conveniently. The movable swing block 3 with a small amount of left and right rotation can flexibly adapt to different parts and be adjusted according to the actual situation, thereby ensuring the shaping effect. This device reduces the secondary shaping operation caused by springback by quickly and effectively processing parts, thereby improving the overall working efficiency and the production speed of products.

[0030] Specifically, referring to Figures 1-4 , the wear-resistant plate 41 is inclined and a graphite coating is provided on the surface of the wear-resistant plate 41.

[0031] In this embodiment, by providing a graphite coating on one side of the wear-resistant plate 41, graphite has natural lubrication characteristics, which can effectively reduce the friction between objects, extend the service life of the equipment, and reduce wear.

[0032] Specifically, referring to Figures 1-4 On both sides of the inner wall of the installation groove at the lower end of the upper cover plate 1, there are inclined surfaces. On both sides of the lower end of the movable swing block 3, there are inclined surfaces. On one side of the upper end of the shaping lower die 5, there is an inclined surface.

[0033] In this embodiment, the inclined surfaces are provided on both sides of the inner wall of the installation groove at the lower end of the upper cover plate 1, so that there is a certain swinging distance between both sides of the movable swing block 3 and the inner wall of the installation groove at the lower end of the upper cover plate 1. Thus, when the rotating mechanism 11 drives the movable swing block 3 to rotate, the movable swing block 3 can perform a small amount of left - right rotation, thereby improving flexibility and applicability.

[0034] Specifically, referring to Figures 1-4 The wear - resistant plate 41 and the backrest 4 are detachably connected by bolts.

[0035] In this embodiment, the wear - resistant plate 41 and the backrest 4 are detachably connected by bolts, making it convenient to maintain and disassemble the wear - resistant plate 41 subsequently, and reducing the pressure of maintenance.

[0036] The movable swing block shaping mechanism of the present utility model:

[0037] During the actual use process, when the movable swing block 3 is driven by an external transmission mechanism to move downward to shape and punch one side of the process strip 2, the control of the rotating mechanism 11 can drive the movable swing block 3 to perform a small amount of rotational adjustment. The provided backrest 4, in cooperation with the wear - resistant plate 41 and the shaping lower die 5, can limit the movable swing block 3. By setting a graphite coating on one side of the wear - resistant plate 41, friction can be reduced and lubrication can be achieved, and finally one side of the process strip 2 is shaped, effectively dealing with the springback problem during the shaping of one side of the process strip 2.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
