Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a slag removal device for die castings. Background Technology

[0002] In the processing of metal products, die casting is often used for die casting, such as for copper, zinc, aluminum, and aluminum alloy products. Due to the technical characteristics and venting requirements of existing die casting technology, the die casting blanks (castings) have relatively thick gates and a certain number of slag pockets around them. Before the castings are machined on CNC machine tools, the slag pockets and gates around them must be removed.

[0003] Some automated slag removal equipment has emerged in the market, mostly using robotic arms to hold pneumatic hammers. However, these devices are typically complex in structure and expensive. More importantly, during the hammering process, the casting needs to be stably clamped to prevent wobbling, while simultaneously allowing for easy loading and unloading. Existing equipment often separates the clamping and positioning mechanism from the processing mechanism, requiring additional transfer devices to move the casting from the loading / unloading position to the processing position, increasing the complexity of the equipment and manufacturing costs.

[0004] Therefore, there is an urgent need for a slag removal device that is compact, highly automated, and can effectively clamp castings. Utility Model Content

[0005] To solve the above technical problems.

[0006] This application provides a slag removal device for die castings, including a worktable, and further including a movable module, a casting clamping assembly and a transfer mechanism installed on the worktable; The mobile module is equipped with a pneumatic hammer for striking the slag bag, and the mobile module drives the pneumatic hammer to move along the X and Y directions; The transfer mechanism includes a transfer guide rail, a transfer slide, a lifting guide plate, and a push rod and guide rod assembly for driving the lifting guide plate to move in the vertical direction. The transfer slide is slidably mounted on the transfer guide rail, and the casting clamping assembly is fixedly mounted on the transfer slide. The transfer mechanism also includes a right-angle connecting rod and an abutting rod. The right-angle connecting rod is hinged to the worktable via a mounting base and a torsion spring, and the abutting rod is fixedly installed on the lifting guide plate. One end of the right-angle connecting rod is provided with an abutting wheel that cooperates with the abutting rod, and the other end is provided with a long strip-shaped sliding groove. The transfer slide is provided with a connector that slides with the sliding groove. When the push rod drives the lifting guide plate to move downward, the abutting rod presses the abutting wheel end of the right-angle connecting rod, causing the right-angle connecting rod to rotate around the hinge point. Then, through the cooperation of the slide groove and the connecting head, the transfer slide and the casting clamping assembly are pulled along the transfer guide rail from the loading position to the processing position.

[0007] Furthermore, the moving module and the pneumatic hammer are installed at the lower end of the lifting guide plate and move synchronously with the lifting guide plate.

[0008] Furthermore, the casting clamping assembly includes a clamping base and two clamping heads, the two clamping heads being respectively hinged to both ends of the clamping base, and a cylinder being installed in the middle of the clamping base, the cylinder driving the two clamping heads to open and close synchronously through a connecting rod assembly.

[0009] Furthermore, there are two transfer guide rails, which are arranged in parallel on the worktable.

[0010] Furthermore, the push rod is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0011] The advantages of this utility model compared with the prior art are: 1. This application ingeniously utilizes a transfer mechanism (lifting guide plate, right-angle connecting rod, etc.) to simultaneously drive the downward pressing of the moving module (pneumatic hammer) and the horizontal transfer of the casting clamping assembly, achieving synchronous, opposite-direction movement of the casting and the pneumatic hammer. This design completes two actions with a single power source (push rod), simplifying the mechanism, reducing costs, and achieving a high degree of automation. It liberates workers from heavy manual hammering operations, requiring only loading and unloading operations, significantly improving production efficiency and operational safety.

[0012] 2. After the casting is placed by the worker at the loading position, it is automatically fed into the processing position through mechanical linkage, avoiding secondary positioning errors. At the same time, the robust clamping components can firmly fix the casting during processing, preventing it from shaking due to impact, ensuring the removal effect and protecting the casting body.

Detailed Implementation

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figures 1 to 3 As shown; The present invention provides a slag removal device for die castings, which mainly includes a worktable 1, a moving module 2, a casting clamping assembly 3, and a transfer mechanism 4.

[0017] The movable module 2 and the pneumatic hammer 21 are installed at the lower end of the lifting guide plate 43. The movable module 2 can be a common cross slide module, which drives the pneumatic hammer 21 to move in the XY plane to position the slag pots at different locations on the casting.

[0018] The casting clamping assembly 3 is fixedly mounted on the transfer slide 42 by bolts. Its clamping base 31 is used to support the casting, and the clamping heads 32 at both ends are driven by the cylinder 33 in the middle through the connecting rod assembly 34 to achieve synchronous opening and closing, thereby clamping or releasing the casting.

[0019] The transfer mechanism 4 is the core of this utility model. Two transfer guide rails 41 are fixed parallel to each other on the worktable 1. The transfer slide 42, through a slider cooperating with the transfer guide rails 41, can slide under external force, and its movement trajectory defines the loading position and processing position. The lifting guide plate 43 is guided by the guide rod assembly 45 and driven to move up and down by the push rod 44 (a cylinder is used in this embodiment). The right-angle connecting rod 46 is hinged to the worktable 1 through the mounting base 48, and the torsion spring 49 gives it a tendency to return to its original position. The abutment rod 47 is fixed to the lifting guide plate 43.

[0020] Its working process is as follows: Initial state (loading): Push rod 44 is in the retracted state, and lifting guide plate 43 is in the high position. Under the action of torsion spring 49, right-angle connecting rod 46 remains stationary. Figure 2 As shown in the tilted state, the transfer slide 42 is located at the loading position on the left side of the guide rail. The worker places the casting to be processed into the clamping seat 31 and starts the cylinder 33, which drives the two clamping heads 32 to close and clamp the casting through the connecting rod assembly 34.

[0021] Transfer and Processing: The push rod 44 is activated, pushing the lifting guide plate 43 downwards. The abutment rod 47 fixed to it descends accordingly, pressing against the abutment wheel 461 at one end of the right-angle connecting rod 46, forcing the right-angle connecting rod 46 to overcome the force of the torsion spring 49 and rotate clockwise around the mounting base 48. Simultaneously, the slide groove 462 at the other end of the right-angle connecting rod 46 slides relative to the connector 421 on the transfer slide table 42, generating a pulling force that horizontally pulls the transfer slide table 42 from the loading position to the processing position. At the same time, the moving module 2 and pneumatic hammer 21 installed at the lower end of the lifting guide plate 43 also descend synchronously.

[0022] In-position processing: When the lifting guide plate 43 descends to its final position, the transfer slide 42 precisely reaches the processing position, and the casting is accurately delivered below the pneumatic hammer 21. At this time, the moving module 2 drives the pneumatic hammer 21 to move directly above the slag bag and perform the hammering operation. Because the casting is firmly clamped and has no degree of freedom in the horizontal direction, the hammering process is stable and reliable.

[0023] Reset: After processing, push rod 44 retracts, pulling lifting guide plate 43 upward. The pressure of abutment rod 47 on right-angle connecting rod 46 is released, and right-angle connecting rod 46 resets counterclockwise under the action of torsion spring 49, and pushes transfer slide 42 back to the loading position through slide groove 462. The operator releases clamping head 32, removes the processed casting, and can start the next work cycle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
