Description

Technical Field

[0001] The present application relates to the field of stamping, and in particular to a stamping device for a guide arm. Background Art

[0002] The automobile guide arm is installed between the axle and the guide arm bracket. The automobile guide arm has a shock-absorbing effect. During the driving process of the car, it reduces the impact caused by ground factors during driving and ensures the comfort of the ride. The automobile guide arm also has a guiding function, attenuating the vibration caused by the elastic system, transmitting the reaction force and torque from the longitudinal, vertical or lateral direction, so that the wheels move along a certain trajectory compared with the body, playing a guiding role.

[0003] Typically, guide arms are produced using a stamping machine. This traditional press consists of a frame with a stamping device and a lower die mounted on top. During operation, the operator places a strip of sheet material on the lower die, which is then punched through the stamping device. Afterward, the operator removes the workpiece and pushes the sheet material forward for another press. However, after repeated pushes, the end of the sheet material away from the lower die falls under its own weight, causing it to bend. This can affect subsequent presses and, consequently, the accuracy of the press. Utility Model Content

[0030] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a stamping device for a guide arm, such as Figure 1 As shown, the machine comprises a frame 1, to which a lower die 2 is fixedly connected, on which a feed plate is placed. A support plate 3 is provided on the frame 1, located to one side of the lower die 2 in the direction of the sheet's movement. The feed plate is placed on the support plate 3, and the surface of the support plate 3 is flush with the upper end surface of the lower die 2. After a sheet is stamped once, the operator pushes the sheet onto the support plate 3. Since the surface of the support plate 3 is flush with the upper end surface of the lower die 2, the sheet does not bend, improving stamping accuracy and facilitating the stamping process.

[0033] like Figure 2 and 3 As shown, multiple first support blocks 11 are fixedly connected to the frame 1 and located on both sides of the support plate 3. Multiple first support blocks 11 are provided on the frame 1 and on both sides of the support plate 3. A support groove 111 is defined in the support plate 3, and both sides of the support plate 3 contact the groove walls of the support groove 111. The first support blocks 11 support both sides of the support plate 3, thereby supporting the support plate 3. The support groove 111 limits the position of the support plate 3, reducing the possibility of the support plate 3 shifting and facilitating the support plate 3 to support the sheet material.

[0034] like Figure 2 and 3 As shown, the first support block 11 is rotatably connected to a limit block 12, which can be rotated to mate with the surface of the support plate 3. A limit bar 31 is fixedly connected to the support plate 3, and a limit slot 121 is provided on the limit block 12. The limit slot 121 is for the limit bar 31 to be inserted into. The limit bar 31 can limit the limit block 12, thereby improving the position accuracy of the limit block 12. After the support plate 3 is placed on the first support block 11, the operator rotates the limit block 12 until the limit block 12 rotates to mate with the surface of the support plate 3. The limit blocks 12 on both sides can limit the sheet material, reducing the possibility of deviation during sheet material movement, improving the stamping accuracy of the sheet material, and facilitating the sheet material stamping operation.

[0035] like Figure 4 and5 As shown, a second support block 21 is fixedly connected to the side of the lower mold 2 facing the support plate 3. The second support block 21 abuts the end of the support plate 3 closest to the lower mold 2 and is located below the support plate 3. An insert block 211 is fixedly connected to the second support block 21, and an insert groove 32 is defined on the support plate 3 for the insert block 211 to insert into. The second support block 21 provides support for the end of the support plate 3 closest to the lower mold 2. When the support plate 3 is placed on the second support block 21, the insert block 211 inserts into the insert groove 32. The insert block 211 can position the support plate 3, reducing the possibility of the support plate 3 shifting and facilitating the support plate 3's support of the sheet material.

[0036] like Figure 4 As shown, an auxiliary plate 4 is fixedly connected to the bottom of the support plate 3. The auxiliary plate 4 moves closer to the lower mold 2. An elastic member is provided on the auxiliary plate 4, which is a spring 41. One end of the spring 41 is fixedly connected to the auxiliary plate 4, and the other end is fixedly connected to the lower mold 2. Under normal circumstances, the spring 41 applies a pulling force to the auxiliary plate 4, causing the auxiliary plate 4 to move closer to the lower mold 2. When the support plate 3 is placed on the first support block 11 and the second support block 21, the spring 41 applies a pulling force to the auxiliary plate 4, thereby applying a pulling force to the support plate 3, causing one end of the support plate 3 to abut against the lower mold 2, further reducing the possibility of the support plate 3 deflecting.

[0037] The implementation principle of a stamping device for a guide arm in the embodiment of the present application is as follows:

[0038] The operator moves the support plate 3 to the first support block 11 and the second support block 21. At this time, the support plate 3 is embedded in the support groove 111, and the embedding block 211 is embedded in the embedding groove 32, thereby limiting the support plate 3 and reducing the possibility of the support plate 3 being offset; then the limit block 12 is rotated to make the limit block 12 rotate to fit the plate surface of the support plate 3. The limit block 12 can limit the movement of the material plate and reduce the possibility of offset when the material plate moves; the spring 41 can apply tension to the auxiliary plate 4, thereby applying tension to the support plate 3, so that one end of the support plate 3 abuts against the lower mold 2, thereby improving the stability of the support plate 3 and further limiting the support plate 3.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
