[0002] For fender stamping dies, in order to reduce the number of processes and dies, the trimming of the wheel arch area is usually completed in one process, that is, by combining the trimming insert of the upper die and the scrap cutter of the lower die. This trimming method can ensure that the scrap is cut off in one process.

[0003] However, this trimming method also has obvious drawbacks—because the trimming insert cuts waste material along the product edge, and in order to ensure that the waste material can fall off, a waste material cutter must be designed in a direction perpendicular to the product edge. This results in the cut waste material being closed-off, thus getting stuck on the upper surface of the waste material cutter and unable to be discharged from the mold. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] Example

[0029] The specific embodiments of this utility model are as follows: Figure 1-4 As shown, a scrap lifting device for trimming the fender wheel arch area includes a top material block 1, which is L-shaped. A cylinder 3 is vertically arranged below the top material block 1. The power output end of the cylinder 3 is located at its upper end and is hinged to the bottom of the top material block 1 via a first hinge assembly 2. A second hinge assembly 5 is also provided on one side of the first hinge assembly 2 for hinged to the scrap knife.

[0030] To install the device, a downwardly extending clearance groove needs to be pre-set on the upper surface of the waste cutter. The cylinder 3 is then fixedly installed vertically in the clearance groove. At this time, the bottom of the top block 1 is hinged to the power output end of the upper end of the cylinder 3 through the first hinge assembly 2. At the same time, the bottom of the top block 1 is also hinged to the upper surface of the waste cutter through the second hinge assembly 5, thereby completing the embedded installation of the device on the waste cutter.

[0031] In use, the initial horizontal height of the top block 1 is lower than the upper edge of the scrap cutter's blade. The material to be cut is placed normally on the lower die and is not affected by this device. As the trimming process begins, the upper die descends and approaches the lower die. Then, the trimming insert of the upper die and the scrap cutter of the lower die engage normally to complete the trimming of the material to be cut. At this time, the scrap around the scrap cutter falls into the scrap channel of the lower die as the trimming insert cuts. Next, the upper die rises and leaves the lower die. As the upper die leaves, closed scrap remains on the upper surface of the scrap cutter. At this time, the cylinder 3 is activated, driving one side of the top block 1 to rise. Under the action of the first hinge assembly 2 and the second hinge assembly 5, the top block 1 forms a movement trajectory similar to a "rock-throwing machine," thereby pushing the closed scrap left on the upper surface of the scrap cutter away from the scrap cutter and causing the scrap to fall into the scrap channel of the lower die. Finally, after the scrap on the upper surface of the scrap cutter is cleaned, the cylinder 3 retracts and resets, and the die can perform the next trimming operation.

[0032] This device actively pushes away the waste material remaining on the waste cutter after the mold completes the trimming of the material, allowing it to fall into the waste discharge channel and be discharged. Therefore, this device solves the problem of closed-off waste material remaining on the surface of the waste cutter after cutting, ensuring that all waste material is discharged from the mold after the fender trimming process is completed, thus avoiding the inconvenience and potential injury risks caused by manual waste collection.

[0033] To connect the top material block 1 to the first hinge assembly 2, the top material block 1 is hinged to the first hinge assembly 2 via a hinge plate vertically positioned at its bottom. Specifically, the first hinge assembly 2 includes a first hinge lug 21, the upper part of which is located outside the two side surfaces of the hinge plate, and the bottom of which is fixedly connected to the power output end of the cylinder 3. The first hinge assembly 2 also includes a first rotating pin 22 that passes horizontally through the first hinge lug 21 and the hinge plate, and the hinge plate has a hinge slot 12 for the first rotating pin 22 to pass through. In this embodiment, to prevent the first rotating pin 22 from falling off, a first anti-detachment pin 23 is inserted into the portion of the first rotating pin 22 located outside the first hinge lug 21.

[0034] Furthermore, to achieve the connection between the top material block 1 and the second hinge assembly 5, the top material block 1 is hinged to the second hinge assembly 5 via a hinge ear 11 located at its bottom. Specifically, the second hinge assembly 5 includes a second hinge ear seat 51, the upper part of which is located outside both sides of the hinge ear 11, and the bottom of which is fixedly connected to the waste cutter. The second hinge assembly 5 also includes a second rotating pin 52 that passes horizontally through the second hinge ear seat 51 and the hinge ear 11. In this embodiment, to prevent the second rotating pin 52 from falling off, a second anti-detachment pin 53 is inserted into the portion of the second rotating pin 52 located outside the second hinge ear seat 51. Simultaneously, to achieve the fixed connection between the second hinge ear seat 51 and the waste cutter, the bottom of the second hinge ear seat 51 is fixedly connected to the waste cutter via an ear seat fixing screw 54.

[0035] In addition, regarding the installation of cylinder 3, cylinder mounting seats 4 are provided on both sides of cylinder 3, and the two cylinder mounting seats 4 are arranged opposite each other. A mounting seat fixing screw 41 is vertically installed on the lower part of the cylinder mounting seat 4. The cylinder mounting seat 4 is fixed in the clearance groove of the waste cutter by the mounting seat fixing screw 41, and the cylinder 3 is installed on the cylinder mounting seat 4.

[0036] In this embodiment, a cylinder mounting sleeve 31 is fixedly sleeved on the outer wall of the cylinder 3. Two mounting shafts 32, corresponding one-to-one with the cylinder mounting seat 4, are vertically arranged on the outer wall of the cylinder mounting sleeve 31. The free ends of the mounting shafts 32 are rotatably connected to the cylinder mounting seat 4, which can prevent the cylinder 3 from getting stuck due to the output end not extending / retracting smoothly during the process of driving the top material block 1.

[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
