Description

Technical Field

[0001] This utility model relates to the field of steering knuckle processing technology, specifically to a cutting device for steering knuckle processing. Background Technology

[0002] The steering knuckle is a key component of the car's suspension system, mainly connecting the wheels, steering system, and braking system. It is crucial to the vehicle's handling and safety. During the manufacturing process, it needs to be processed by forging, and the edges of the forged workpiece are relatively rough.

[0003] For example, patent application number 202122110504.7 published on the China Patent Network, entitled "A Forging and Trimming Device for Automobile Steering Knuckle Production," includes a hydraulic cylinder, a pressing plate, a trimming piece, and connecting blocks. A connecting frame is fixed to one end of the upper surface of the frame, and a hydraulic cylinder is fixed to one end of the upper surface of the connecting frame. The output end of the hydraulic cylinder is fixed to the pressing plate. The trimming piece is fixed to the inner side of the frame via two connecting blocks. A groove for placing the steering knuckle is provided inside the trimming piece, and a beveled cutting end is provided at the top of the trimming piece. Through structural design, this invention allows burrs to slide down along the cutting end at the top of the trimming piece to the outside of the trimming piece during burr removal, preventing burrs from falling into the groove and affecting the normal trimming of the steering knuckle. Furthermore, the device allows for easy removal of the steering knuckle from the device.

[0004] However, the existing edge-cutting device has a rather cumbersome way of discharging waste, which requires opening an opening at the bottom of the equipment to discharge waste. However, the opening will affect the structural strength of the equipment and interfere with the installation of the steering knuckle workpiece.

[0005] Therefore, it is necessary to redesign and modify the edge-cutting device used for steering knuckle processing. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cutting device for steering knuckle processing, which has the advantage of facilitating waste discharge. This solves the problem that the existing cutting device has a cumbersome waste discharge method, which requires opening an opening at the bottom of the device for waste discharge. However, such openings can affect the structural strength of the device and interfere with the installation of the steering knuckle workpiece.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a trimming device for processing steering knuckles, comprising a frame;

[0008] A stamping and trimming component located at the top of the frame;

[0009] A connecting block is fixedly connected to the back of the frame, a shaft is inserted into the inside of the connecting block, a swing arm is fixedly connected to the surface of the shaft, and a lower mold is fixedly connected to the inner side of the swing arm. The swing arm can swing the lower mold by using the shaft. A transmission structure is provided at the bottom of the frame, and the transmission structure can control the swing arm to swing.

[0010] In a preferred embodiment of this utility model, the transmission structure includes a connecting frame fixedly connected to the bottom of the frame, a screw movably connected to the inside of the connecting frame via a bearing, a transmission plate threadedly connected to the surface of the screw, extension plates fixedly connected to both sides of the transmission plate, a gear plate fixedly connected to the side of the extension plate away from the transmission plate, and gears fixedly connected to both sides of the shaft, the gears being located at the bottom of the gear plate and meshing with the gear plate.

[0012] In a preferred embodiment of this invention, both ends of the transmission rod are fixedly connected to a force-bearing rod, and a pressing plate is fixedly connected to the surface of the extension plate. The pressing plate extends to the bottom of the force-bearing rod from the side away from the extension plate. The pressing plate is configured in a bent shape, and when the pressing plate moves with the extension plate, it can use the extension portion to press the force-bearing rod to make it swing.

[0013] In a preferred embodiment of this invention, a roller is movably connected to the side of the force-bearing rod away from the transmission rod, and the outer surface of the roller contacts the top of the extrusion plate.

[0014] As a preferred embodiment of the present invention, the surface of the lower mold is provided with an opening, which is used to accommodate the swing of the bearing plate and the steering knuckle workpiece.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model avoids opening a waste discharge opening at the bottom of the frame by using the linkage design of the connecting block, shaft and swing arm on the back of the frame, thus ensuring the overall structural strength and stability of the frame. The waste is dumped by using the swinging motion of the lower mold, which simplifies the traditional waste discharge structure and reduces the complexity of the equipment and maintenance costs.

[0017] 2. This utility model converts rotary motion into linear motion through a screw transmission structure, and then converts it into rotary motion of a rocker arm through the meshing of a toothed plate and a gear, thereby achieving precise control of the swing angle of the lower mold.

[0018] 3. The bearing plate of this utility model can swing forward through the transmission rod, so that the workpiece is automatically moved out of the processing area after processing, which makes it convenient for operators to quickly pick up and put down the workpiece. The movable block cooperates with the transmission rod to ensure that the bearing plate maintains a fixed position during processing, avoiding workpiece displacement and affecting the cutting accuracy.

[0019] 4. This utility model, through the bending shape design of the extrusion plate, transforms the linear motion of the transmission structure into the rotational motion of the transmission rod by pushing the force rod through the inclined surface when the transmission plate moves, thereby achieving synchronization between the swing of the bearing plate and the swing of the lower mold.

[0020] 5. This utility model converts sliding friction into rolling friction by having rollers contact the extrusion plate, reducing component wear and extending equipment life. The rollers make the contact between the force rod and the extrusion plate smoother, avoiding jamming and improving linkage reliability.

[0021] 6. This utility model provides clearance space for the forward swing of the support plate through the opening in the lower mold, avoiding collision between the mold and the workpiece / support plate during the resetting process. The opening is used to accommodate the swing of the support plate and can also serve as a temporary storage area for waste materials, simplifying the structural design. Attached Figure Description

[0027] 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.

[0028] like Figures 1 to 4 As shown, the present invention provides a trimming device for machining steering knuckles, comprising a frame 1;

[0029] The stamping and trimming component 2 is installed at the top of the frame 1;

[0030] A connecting block 3 is fixedly connected to the back of the frame 1. A shaft 4 is inserted into the inside of the connecting block 3. A swing arm 5 is fixedly connected to the surface of the shaft 4. A lower mold 6 is fixedly connected to the inner side of the swing arm 5. The swing arm 5 can swing the lower mold 6 using the shaft 4. A transmission structure 7 is provided at the bottom of the frame 1. The transmission structure 7 can control the swing arm 5 to swing.

[0031] refer to Figure 3 The transmission structure 7 includes a connecting frame 8 fixedly connected to the bottom of the frame 1. A screw 9 is movably connected inside the connecting frame 8 via a bearing. A transmission plate 10 is threadedly connected to the surface of the screw 9. Extension plates 11 are fixedly connected to both sides of the transmission plate 10. A gear plate 12 is fixedly connected to the side of the extension plate 11 away from the transmission plate 10. Gears 13 are fixedly connected to both sides of the shaft 4. The gears 13 are located at the bottom of the gear plate 12 and mesh with the gear plate 12.

[0032] As a technical optimization of this utility model, the rotational motion is converted into linear motion through the screw 9 transmission structure 7, and then converted into the rotational motion of the swing rod 5 through the meshing of the toothed plate 12 and the gear 13, so as to achieve precise control of the swing angle of the lower mold 6.

[0033] refer to Figure 1 A movable block 14 is fixedly connected to the front of the frame 1. A transmission rod 15 is movably connected inside the movable block 14. A bearing plate 16 is fixedly connected to both sides of the surface of the transmission rod 15. A steering knuckle workpiece 17 is inserted into the top of the bearing plate 16. The bearing plate 16 can carry the steering knuckle workpiece 17 and swing it forward.

[0034] As a technical optimization of this utility model, the support plate can swing forward through the transmission rod 15, so that the workpiece is automatically moved out of the processing area after processing, which makes it convenient for operators to quickly pick up and put down the workpiece. The movable block 14 cooperates with the transmission rod 15 to ensure that the support plate 16 maintains a fixed position during processing, so as to avoid the workpiece shifting and affecting the cutting accuracy.

[0035] refer to Figure 1Both ends of the transmission rod 15 are fixedly connected to the force rod 18. The surface of the extension plate 11 is fixedly connected to the extrusion plate 19. The side of the extrusion plate 19 away from the extension plate 11 extends to the bottom of the force rod 18. The extrusion plate 19 is set in a bent shape. When the extrusion plate 19 moves with the extension plate 11, it can use the extension to extrude the force rod 18 to make it swing.

[0036] As a technical optimization of this utility model, by designing the bending shape of the extrusion plate 19, when the transmission plate 10 moves, the inclined surface contacts and pushes the force rod 18, converting the linear motion of the transmission structure 7 into the rotational motion of the transmission rod 15, thereby achieving synchronization between the swing of the bearing plate 16 and the swing of the lower mold 6.

[0037] refer to Figure 4 A roller 20 is movably connected to the side of the force-bearing rod 18 away from the transmission rod 15, and the outer surface of the roller 20 contacts the top of the extrusion plate 19.

[0038] As a technical optimization of this utility model, the contact between the roller 20 and the extrusion plate 19 transforms sliding friction into rolling friction, reducing component wear and extending equipment life. The roller 20 makes the contact between the force rod 18 and the extrusion plate 19 smoother, avoiding jamming and improving linkage reliability.

[0039] refer to Figure 2 The surface of the lower mold 6 has an opening 21, which is used to accommodate the swing of the bearing plate 16 and the steering knuckle workpiece 17.

[0040] As a technical optimization of this utility model, the opening 21 in the lower mold 6 provides a clearance space for the forward swing of the support plate 16, avoiding collision between the mold and the workpiece / support plate 16 during the reset process. The opening 21 is used to accommodate the swing of the support plate 16 and can also serve as a temporary storage area for waste materials, simplifying the structural design.

[0041] The working principle and usage process of this utility model are as follows: The operator inserts the steering knuckle workpiece 17 into the insertion position of the bearing plate 16. At this time, the device is in its initial state. The lower mold 6 is fixed in a horizontal position by the swing rod 5 and the shaft 4, aligned with the stamping and trimming component 2 to ensure trimming accuracy. When the steering knuckle workpiece 17 is installed, the stamping and trimming component 2 is activated to trim the steering knuckle workpiece 17. The upper mold presses down, cooperating with the lower mold 6 to complete the trimming. Scrap material is temporarily stored in the lower mold 6. After trimming is completed, the transmission structure 7 synchronously drives the scrap material discharge and workpiece unloading. The drive device drives the screw 9 to rotate, and the transmission plate 10 moves along the screw... 9. When the axis moves, the extension plate 11 and the toothed plate 12 move accordingly. The toothed plate 12 meshes with the gears 13 on both sides of the shaft 4, driving the shaft 4 to rotate. This causes the swing rod 5 and the lower mold 6 to swing outward from the frame 1. After swinging, the lower mold 6 completes the flipping and dumps the waste material inside. When the extension plate 11 first moves, it will first use the extrusion plate 19 to contact the roller 20 on the force rod 18, pushing the transmission rod 15 to rotate around the movable block 14. The transmission rod 15 drives the bearing plate 16 to swing forward, moving the trimmed workpiece to the preset unloading position. The pre-swinging bearing plate 16 will not affect the swinging of the lower mold 6.

[0042] In summary, this edge-cutting device for steering knuckle processing, through the linkage design of the connecting block 3, shaft 4 and swing arm 5 on the back of the frame 1, avoids opening the waste discharge opening 21 at the bottom of the frame 1, ensuring the overall structural strength and stability of the frame 1. The waste is dumped by the swinging action of the lower mold 6, which simplifies the traditional waste discharge structure and reduces the complexity of the equipment and maintenance costs.
