Description

Technical Field

[0001] The utility model relates to the technical field of automobile component manufacturing, in particular to a tool for punching a mirror frame base stub. Background Art

[0002] In the production of automotive mirror frame bases, base slugs are often excess parts formed during the injection molding process, affecting the overall appearance of the product. If not promptly addressed, these slugs can further expand, squeezing the mold and causing partial collapse, resulting in permanent damage. Therefore, to meet the dual requirements of base appearance and quality, these slugs must be removed promptly.

[0003] Traditionally, frame bases are often cut manually. This is time-consuming and labor-intensive, making it difficult to position the frame base and requiring multiple cuts, resulting in low efficiency. Furthermore, the lack of an effective fixing mechanism during manual cutting can easily lead to chipping of the product edges. This results in many substandard frame bases due to improper cutting, further increasing production and labor costs.

[0004] Therefore, it is urgent to develop a punching device for the frame base material head to improve the manual cutting speed and the product qualification rate of the frame base. Utility Model Content

[0042] Example 1:

[0043] This embodiment provides a frame base stub punching device, which specifically includes the following components:

[0044] Base plate 1;

[0045] A support 2 provided on the base plate 1;

[0046] The positioning block 3 provided on the bottom plate 1 is used to place the frame base to be cut;

[0047] The punching assembly 4 provided on the support 2 is used to cut the material head of the frame base;

[0048] A handle 5 provided on the support 2, connected to the punching assembly 4, for applying downward pressure to the punching assembly 4;

[0049] A connecting rod 6 provided between the handle 5 and the punching assembly 4;

[0050] The reset assembly 7 provided on the support 2 is connected to the punching assembly 4 and is used to drive the punching assembly 4 to reset when the pressure is released.

[0051] During use, the frame base to be cut is placed on the positioning block 3, with the blank directly below the punching assembly 4. The handle 5 is then pressed, which transmits pressure to the punching assembly 4 via the connecting rod 6, allowing the punching assembly 4 to punch the blank. Once the blank is punched, the handle is released, and the punching assembly 4 resets via the reset assembly 7, allowing the next frame base to be placed and the punching operation to be repeated.

[0052] Example 2:

[0053] This embodiment provides a frame base material punching device, which specifically includes a base plate 1, a support 2, a positioning block 3, a punching assembly 4, a handle 5, a connecting rod 6 and a reset assembly 7.

[0054] The base plate 1 of this embodiment is provided with feet 11 at each of its four corners, allowing the entire device to be securely placed on a workbench. The base plate 1 is also provided with positioning blocks 3, each with positioning protrusions 31 that engage with the frame base. This allows the frame base to be precisely positioned against the positioning blocks 3, enabling rapid positioning of the frame base.

[0055] The base plate 1 of this embodiment is provided with a vertical support 2, on which is provided a punching assembly 4 for cutting the material head and a handle 5 for applying downward pressure to the punching assembly 4. Specifically, the punching assembly 4 includes a first connecting seat 41 provided on the support 2, a connecting block 42 rotatably provided on the first connecting seat 41, a knife seat 43 provided on the connecting block 42, and a blade 44 provided on the knife seat 43. A support seat 12 is provided on the base plate 1, and a gap is left between the support seat 12 and the positioning block 3 for the blade 44 to fall. Furthermore, a limit block 13 is provided on the base plate 1. The limit block 13 is located directly below the connecting block 42 and is used to effectively limit the depth of the blade 44's fall, thereby limiting the punching depth and ensuring the consistency and accuracy of each punching. A second connecting seat 52 is provided on the support 2, on which the handle 5 is rotatably provided. A connecting rod 6 is also connected between the handle 5 and the connecting block 42 of the punching assembly 4. A first connector 45 is provided on the connecting block 42 , a second connector 51 is provided on the handle 5 , and both ends of the connecting rod 6 are movably connected to the first connector 45 and the second connector 51 , respectively.

[0056] The support 2 of this embodiment is also provided with a reset assembly 7. This reset assembly 7 is connected to the punch assembly 4 and is used to reset the punch assembly 4 when pressure is released. Specifically, the reset assembly 7 includes a first fixing seat 71 provided on the support 2 and a second fixing seat 72 provided on the punch assembly 4. A tension spring 73 is connected between the first and second fixing seats 71 and 72. Each of the first and second fixing seats 71 and 72 is provided with a spring connector 74, with each end of the tension spring 73 connected to a corresponding spring connector 74.

[0057] The usage process of this embodiment is as follows:

[0058] (1) Place the frame base to be cut on the positioning block 3 and position it with the positioning protrusion 31 on the positioning block 3, and make the material head directly below the blade 44 of the punching assembly 4.

[0059] (2) Then, the handle 5 is pressed, and the handle 5 transmits the pressure to the connecting block 42 of the punching assembly 4 through the connecting rod 6. The connecting block 42 drives the blade 44 downward, so that the blade 44 cuts the material head and the blade 44 falls between the support seat 12 and the positioning block 3.

[0060] (3) After the cutting of the material head is completed, stop pressing the handle 5, and the tension spring 73 in the stretched state begins to shrink and reset, driving the connecting block 42 and the blade 44 to lift up and reset, and then driving the handle 5 to reset through the connecting rod 6.

[0061] (4) Clean the waste on the tooling, place the next frame base to be cut, repeat the above punching operation, and continue the cutting operation.

[0062] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
