[0002] The steering knuckle, also known as the "steering knuckle," is one of the important components of the automotive steering axle. It enables the car to drive stably and transmit driving direction sensitively. After the steering knuckle is forged, a trimming device is needed to remove the burrs on the edge of the steering knuckle.

[0003] In the prior art, a forging trimming device for automobile steering knuckle production, with the publication number "CN216226724U", is designed so that when the burrs are removed, the falling debris can slide down along the cutting end set at the top of the trimming part to the outside of the trimming part, avoiding the debris falling into the groove and affecting the normal trimming of the steering knuckle. In addition, the device can easily remove the steering knuckle from the device.

[0004] However, the above technical solutions and existing technologies have the following drawbacks: Although the trimming device can lift the steering knuckle by pushing the demolding block upward with an electric push rod, the structure still requires a separate power supply line during use. In addition, the operator needs to switch between controlling the hydraulic cylinder and the electric push rod to perform the trimming and lifting work. The ease of use is relatively low, and its practicality needs to be improved. Utility Model Content

The support bases 47 are connected and fixed to the support platform 1 by mounting screws so that the trimming mold 41 can be disassembled and replaced by the staff later.

[0019] A support frame 44 is fixedly connected to the rear side of the upper end face of the support platform 1. The support frame 44 is L-shaped and can support the electric push rod 43. The electric push rod 43 is installed on the front side of the upper end face of the support frame 44. A control panel (shown in the figure) is installed on the left side of the upper end face of the support platform 1, and the control panel is electrically connected to the electric push rod 43. When the electric push rod 43 is working, it can drive the support hanging plate 42 to rise and fall. The support hanging plate 42 is installed at the lower end of the electric push rod 43. The lower end face of the support hanging plate 42 is symmetrically provided with pressing heads 45 on the left and right sides. The pressing heads 45 are connected to the support hanging plate 42 by welding. When the pressing heads 45 move down, they can press down on the car steering knuckle 3 placed in the cutting mold 41.

[0020] A rectangular cavity 11 is provided on the upper surface of the support platform 1. The rectangular cavity 11 can collect and guide the debris cut off by the cutting mold 41 into the debris collection box 12. The debris collection box 12 is inserted into the lower side of the support platform 1 and is connected to the rectangular cavity 11. The debris collection box 12 can collect the cut debris in a concentrated manner so that the staff can transfer it in a concentrated manner.

[0021] Example 2: Based on Embodiment 1, this embodiment sets up a linkage rod 21, a connecting plate 23, and a lifting head 22, so that the support hanging plate 42 can drive the lifting head 22 to move up and down together. So that when the support hanging plate 42 drives the lower pressing head 45 to move up, the lifting head 22 will move up together to lift the car steering knuckle 3 in the cutting mold 41, thereby making it convenient for the staff to remove the car steering knuckle 3.

[0022] The lifting assembly 2 includes a linkage rod 21, a lifting head 22, a connecting plate 23, and a through hole 24. The linkage rods 21 are symmetrically arranged on the left and right sides of the lower end face of the support plate 42. The linkage rods 21 are inserted inside the support platform 1. The linkage rods 21 are connected to the support plate 42 and the connecting plate 23 by welding. The linkage rods 21 can support the connecting plate 23.

The bottom left and right sides of the trimming mold 41 are provided with through holes 24, and the through holes 24 match the lifting head 22. The through holes 24 facilitate the lifting head 22 to be inserted into the trimming mold 41 to perform lifting and lowering actions.

[0023] Working principle: The operator first controls the electric push rod 43 to raise the support plate 42. During this process, the support plate 42 will move the lower pressure head 45 and the linkage rod 21 upward together. The linkage rod 21 will move the lifting head 22 upward together through the connecting plate 23. After the support plate 42 rises to the required height, the car steering knuckle 3 to be trimmed is placed on the trimming mold 41. After placement, the electric push rod 43 is controlled to extend, so that the electric push rod 43 moves the lower pressure head 45 downward through the support plate 42. After the lower pressure head 45 descends a certain distance, it will press down on the car steering knuckle 3, thereby pressing the car steering knuckle 3 into the trimming mold 41. During the downward movement of the car steering knuckle 3... In the process, the cutting edge 46 removes the burrs on the edge of the car steering knuckle 3, and the removed debris falls into the debris collection box 12 through the rectangular cavity 11. At the same time, the lifting head 22 descends synchronously with the support plate 42 to prevent the lifting head 22 from obstructing the smooth descent of the car steering knuckle 3 into the cutting mold 41. After the cutting mold 41 is completely lowered into the cutting mold 41, the electric push rod 43 is retracted again, causing the support plate 42 to move the pressing head 45 and the lifting head 22 upward together. After the lifting head 22 moves upward a certain distance, it passes through the through hole 24 to lift the car steering knuckle 3 in the cutting mold 41, so that the staff can easily remove the car steering knuckle 3.
