Technical Field

[0001] This utility model belongs to the field of automotive die casting processing technology, specifically a cutting device for automotive die casting parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the vehicle. There are many types of automotive parts, and as people's living standards improve, their car consumption is increasing, leading to a growing market for automotive parts. In recent years, automotive parts manufacturers have also been developing rapidly.

[0003] A search revealed that patent CN222985839U discloses a trimming device for automotive aluminum alloy die-cast parts. The device includes a main mounting frame, a top fixing box fixedly connected to the upper surface of the main mounting frame, a trimming device fixedly connected to one side of the inner wall of the top fixing box, and a connecting plate fixedly connected to the upper surface of the top fixing box. The upper surface of the connecting plate has a moving groove and an adapting groove. This invention reduces manual operation by incorporating a trimming device, making the entire process of picking up and placing die-cast parts and trimming seamless, significantly improving production efficiency. It also reduces the risk of workers directly contacting the machinery, improving operational safety. Precise mechanical movement and the assistance of the hydraulic system ensure the accuracy and consistency of trimming, thereby guaranteeing product quality, reducing manual labor, lowering labor intensity, and minimizing material waste and increasing material utilization.

[0004] Based on the aforementioned existing technology, current edge-cutting devices for automotive die-cast parts still have the following problems: during edge cutting, the generated debris and waste materials splash into the fitting groove and moving groove. After prolonged use, debris and waste materials easily accumulate in the groove, making cleaning inconvenient and potentially affecting the movement of the moving block, thus impacting the normal operation of the cutting components. Therefore, we provide an edge-cutting device for automotive die-cast parts to solve these problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a cutting device for die-cast automotive parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for die-cast automotive parts, comprising a worktable, an adjustment mechanism for adjusting the position of the die-casting part is provided in the middle of the worktable, a material discharge groove is provided on the worktable, a protective cover is provided above the material discharge groove and is fixedly connected to the worktable, a sliding groove is provided on the protective cover, a linear module is provided above the protective cover, a slider on the linear module is fixedly connected to a base plate, the base plate slides through into the sliding groove, a cutting machine is installed in the middle of the base plate and is located at the material discharge groove, two supports are fixedly connected to the back of the worktable, the bottom of the linear module is fixedly connected to the top of the two supports, and a positioning mechanism for fixing the die-casting part is provided above the adjustment mechanism and is located between the two supports.

[0007] Preferably, the adjustment mechanism includes an adjustment groove located in the middle of the worktable. A first motor is installed on the front side of the worktable, and the output end of the first motor extends into the adjustment groove. A lead screw is rotatably connected to the inner wall of the adjustment groove, and one end of the lead screw is connected to the output end of the first motor. A sliding seat is slidably disposed in the adjustment groove, and the sliding seat is threaded onto the surface of the lead screw. A rotation mechanism for controlling the rotation of the die-casting part is provided on the sliding seat.

[0008] Preferably, the rotating mechanism includes a second motor, which is installed inside the sliding seat, and the output end of the sliding seat protrudes from the top of the sliding seat. The output end of the sliding seat is fixedly connected to a feeding plate, and the bottom surface of the feeding plate is slidably disposed on the upper surface of the worktable.

[0009] Preferably, the positioning mechanism includes a top frame, which is fixed between the top ends of two supports. An electric push rod is installed at the front end of the top frame, and a compression plate is connected to the telescopic end of the electric push rod.

[0010] Preferably, a sweeping block is fixedly connected to the bottom end of the base plate, and the bottom surface of the sweeping block slides on the inner bottom wall of the material drop trough.

[0011] Preferably, the inner bottom wall of the material discharge trough is provided with a discharge trough on both sides, and the discharge trough extends through to the back of the workbench.

[0012] Preferably, the back of the workbench is provided with two material collection frames, which are located at the outlets of two feeding troughs respectively, and the bottom surface of the workbench is provided with a slot that matches the material collection frames.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated arrangement of a workbench, a material drop chute, a protective cover, a linear module, a bracket, a slide, a base plate, a cutting machine, a material discharge chute, a material collection frame, a material sweeping block, and a positioning mechanism, enables the debris generated during the cutting of die-cast parts to fall into the material drop chute through the enclosure of the protective cover.

This avoids the debris from splashing and accumulating randomly on the workbench, while also ensuring the normal movement of the cutting machine without obstruction and maintaining a hygienic working environment.

[0014] 2. With the adjustment mechanism of this utility model, when the position of the die-casting part needs to be adjusted after one side of the die-casting part has been trimmed, the fixing is first released by the electric push rod. Then, the operation of the first motor is used to pull the die-casting part back away from the material discharge chute. Next, the operation of the second motor drives the material discharge plate to rotate on the worktable, thereby realizing the angle adjustment of the die-casting part. After the adjustment is completed, the first motor is used to extend one side of the trimmed part into the material discharge chute, and the electric push rod is used to fix the extrusion plate. The remaining sides can be trimmed, which solves the problem that the angle adjustment is difficult for personnel due to the heavy weight of the die-casting part. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1, as Figure 1-7 As shown, this embodiment proposes a trimming device for automotive die-cast parts, including a worktable 1. An adjustment mechanism for adjusting the position of the die-cast part is provided in the middle of the worktable 1, allowing the die-cast part to be placed on the adjustment mechanism for subsequent position adjustment. A material discharge chute 13 is provided on the worktable 1 to collect waste materials generated during trimming of the die-cast part. A protective cover 4 is provided above the material discharge chute 13 and is fixedly connected to the worktable 1. The protective cover 4 is used to shield the worktable 1 from flying debris, thus ensuring the working environment on the worktable 1. A sliding groove 7 is provided on the protective cover 4. A linear module 5 is provided above the protective cover 4. A slider on the linear module 5 is fixedly connected to a base plate 11, which slides through the sliding groove 7. A cutting machine 12 is installed in the middle of the base plate 11, located at the material discharge chute 13. The cutting machine 12 utilizes the movement of the linear module 5... The slider moves the base plate 11, allowing it to slide within the groove 7 and move the cutting machine 12 within the discharge chute 13. This allows the die-casting part extending into the discharge chute 13 to be trimmed. Two supports 6 are fixed to the back of the worktable 1, and the bottom of the linear module 5 is fixed to the top of the two supports 6, ensuring the stability of the linear module 5 during operation. A positioning mechanism for fixing the die-casting part is provided above the adjustment mechanism, and the positioning mechanism is located between the two supports 6. When the die-casting part is placed on the worktable 1 and at the adjustment mechanism, the positioning mechanism can press and fix it, thereby ensuring the stability of the die-casting part during trimming and preventing it from sliding. The machinery, parts, and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0019] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details: like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the adjustment mechanism includes an adjustment groove 14, which is located in the middle of the workbench 1. A first motor 2 is installed on the front side of the workbench 1, and the output end of the first motor 2 extends into the adjustment groove 14. A lead screw 17 is rotatably connected to the inner wall of the adjustment groove 14, and one end of the lead screw 17 is connected to the output end of the first motor 2. A sliding seat 18 is slidably arranged in the adjustment groove 14, and the sliding seat 18 is threaded onto the surface of the lead screw 17. A rotating mechanism for controlling the rotation of the die-casting part is provided on the sliding seat 18. With the above structure, when the die-casting part is placed on the workbench 1, it will be supported by the rotating mechanism. Then, the first motor 2 drives the lead screw 17 to rotate, thereby controlling the sliding seat 18 and the rotating mechanism to move, moving the die-casting part closer to the cutting machine 12 for subsequent edge trimming, thus eliminating the need for manual adjustment of the die-casting part's position.

[0020] like Figure 2 , Figure 4 and Figure 5 As shown, the rotating mechanism includes a second motor 20, which is installed inside the sliding seat 18. The output end of the sliding seat 18 protrudes from the top of the sliding seat 18. The output end of the sliding seat 18 is fixedly connected to a feeding plate 15, and the bottom surface of the feeding plate 15 is slidably disposed on the upper surface of the worktable 1. With the above structure, when the front end of the die-casting part moves away from the discharge chute 13, the second motor 20 drives the feeding plate 15 to rotate on the worktable 1, thereby enabling the die-casting part to be angled. The remaining sides can be trimmed, solving the problem that the angle adjustment is difficult for personnel due to the heavy weight of the die-casting part. In addition, under the premise of the operation of the second motor 20, the extrusion plate 10 releases the extrusion and fixation on the die-casting part, thus allowing the die-casting part to rotate normally.

[0021] like Figures 1 to 4 As shown, the positioning mechanism includes a top frame 8, which is fixed between the top ends of two supports 6. An electric push rod 9 is installed at the front end of the top frame 8. The telescopic end of the electric push rod 9 is connected to an extrusion plate 10. The bottom layer of the extrusion plate 10 is made of rubber, which can protect the surface of the die-casting and prevent it from being squeezed and damaged. With the above structure, the operation of the electric push rod 9 can be used to extrude and fix the die-casting on the feeding plate 15 by the extrusion plate 10, thereby ensuring the stability during subsequent edge cutting. The top frame 8 is located behind the worktable 1, so the operator can easily adjust the position of the die-casting from the front of the worktable 1, making it more flexible.

[0022] like Figure 6 and with Figure 7As shown, a sweeping block 19 is fixedly connected to the bottom end of the base plate 11, and the bottom surface of the sweeping block 19 slides on the inner bottom wall of the material drop trough 13. With the above structure, when the die casting is trimmed on the worktable 1, the generated debris will fall into the material drop trough 13. The cutting machine 12 moves through the linear module 5 when trimming, so the sweeping block 19 will sweep away the debris in the material drop trough 13 and sweep the debris to both sides of the material drop trough 13, which is conducive to the unified collection and processing by personnel.

[0023] like Figure 3 , Figure 4 and Figure 6 As shown, the inner bottom wall of the discharge trough 13 is provided with discharge troughs 16 on both sides, and the discharge troughs 16 extend to the back of the workbench 1. With the above structure, the debris in the discharge trough 13 can slide out to the outside of the workbench 1 through the discharge troughs 16, which is convenient for personnel to collect.

[0024] like Figures 1 to 6 As shown, two collection frames 3 are provided on the back of the workbench 1. The two collection frames 3 are located at the outlets of the two discharge troughs 16 respectively, and the bottom surface of the workbench 1 is provided with a slot that matches the collection frame 3. With the above structure, the collection frame 3 can be stably placed under the discharge trough 16, thereby collecting the debris that slides down the discharge trough 16. In addition, in order to prevent the debris in the discharge trough 13 from being too long to fall from the discharge trough 16, discharge ports (not shown in the figure) can be opened on both sides of the inner wall of the discharge trough 13 to the outside of the workbench 1. Therefore, when the base plate 11 moves, the sweeping block 19 will push the longer scraps out from the discharge port on the side of the workbench 1, ensuring the normal movement of the base plate 11 and preventing the accumulation in the discharge trough 13.

[0025] The working principle and usage process of this utility model are as follows: First, the die-cast part is placed on the feeding plate 15, and its movement is controlled by the operation of the first motor 2. The part to be cut is inserted into the blanking groove 13 and aligned with the cutting machine 12. Then, the operation of the electric push rod 9 causes the extrusion plate 10 to press and fix the die-cast part, preventing it from moving randomly. Next, the cutting machine 12 is started, and the linear module 5 is started to drive the base plate 11 to move in the blanking groove 13, so that the cutting machine 12 can cut the side of the die-casting part. During this process, the generated debris will fall into the blanking groove 13. Subsequently, as the base plate 11 moves back and forth, the debris in the blanking groove 13 will be swept to the two discharge grooves 16 by the sweeping block 19 and fall into the collection box. The collection within frame 3 facilitates unified collection and processing by personnel, ensuring the normal movement of the cutting machine 12 without obstruction. When the die-casting part needs to be adjusted after one side is trimmed, the electric push rod 9 is used to release its fixation. Then, the operation of the first motor 2 is used to pull the die-casting part back, moving it away from the discharge chute 13. Next, the operation of the second motor 20 drives the discharge plate 15 to rotate on the worktable 1, thereby achieving angle adjustment of the die-casting part. After adjustment, the first motor 2 is used to extend one side of the trimmed part into the discharge chute 13, and the electric push rod 9 is used to fix the extrusion plate 10. The remaining sides can then be trimmed, solving the problem of personnel being unable to adjust the angle due to the heavy weight of the die-casting part.

[0026] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
