[0028] An embodiment of the utility model provides a control arm forging die.

[0029] See also Figure 1 and Figure 5 , including a pressure component 1, a sensor 2 and a component protective shell 3. The pressure component 1 and the sensor 2 are both existing technologies and will not be described in detail. The setting of the pressure component 1 can effectively control the lifting and lowering of the upper mold 11, thereby completing the stamping operation. The setting of the sensor 2 can send a command signal to the pressure component 1 through contact with the sealing top plate 17 to control the operation of the pressure component 1.

[0030] See also Figure 1The pressure assembly 1 and the component protective shell 3 are fixedly arranged on the upper surface of the mounting base 20. The mounting base 20 is provided with screw holes. The setting of the mounting base 20 ensures the stability of the pressure assembly 1 and the component protective shell 3, and at the same time facilitates the staff to install the mounting base 20 and ensures the stability of the control arm forging die after installation.

[0031] See also Figure 1 、 Figure 2 and Figure 3 The component protective shell 3 is fixedly connected to the lower mold 18. The lower mold 18 is provided with a shaping groove 19. The shaping groove 19 is the shape required for the control arm assembly. The pressure assembly 1 is fixedly connected to the upper mold 11. An L-shaped protective shell 14 is fixedly provided on one side of the upper mold 11. The setting of the L-shaped protective shell 14 can effectively limit its internal components, thereby ensuring the stable movement of its internal components.

[0032] See also Figure 4 and Figure 5 A limit ring 15 is fixedly set inside the L-shaped protective shell 14. The setting of the limit ring 15 can effectively limit the sealing top plate 17 to prevent the sealing top plate 17 from excessive movement. The L-shaped protective shell 14 is fixedly connected to the sealing top plate 17 through a tough spring 16. The sealing top plate 17 slides inside the L-shaped protective shell 14. The setting of the tough spring 16, using the elasticity of the tough spring 16 itself, can effectively reset the sealing top plate 17 and contact with the limit ring 15.

[0033] See also Figure 2 and Figure 5 The sensor 2 is fixedly installed inside the L-shaped protective shell 14, and the bottom of the upper mold 11 is fixedly provided with a shaping protrusion 12 and a clamping guide column 13. The shaping protrusion 12 is adapted to the shaping groove 19, and can effectively press the raw material into the shaping groove 19, thereby obtaining a control arm assembly. The setting of the clamping guide column 13 ensures the stability of the raw material during the stamping process.

[0034] See also Figure 6 The internal rotation of the component protective shell 3 is provided with a linkage bearing 4. The setting of the component protective shell 3 can effectively support its internal components and exert a limiting effect to ensure the stability of its internal components. The setting of the linkage bearing 4 can effectively drive multiple groups of components to rotate synchronously.

[0035] See also Figure 6 A flat gear 5 is fixedly provided on the outer circumference of the linkage bearing 4. There are two groups of flat gears 5. The two groups of flat gears 5 are symmetrically distributed on both sides of the flat worm gear 8. The two groups of flat gears 5 are fixedly connected to the linkage bearing 4. The setting of the two groups of flat gears 5 makes the two groups of flat gears 5 rotate synchronously when the linkage bearing 4 rotates, so that their rotation speeds remain consistent.

[0036] See also Figure 6 The teeth on the outer circumference of the plane gear 5 mesh with the teeth on one side of the bar gear plate 6. A pressure top column 7 is fixed on the top of the bar gear plate 6. The cooperation between the plane gear 5 and the bar gear plate 6, the bar gear plate 6 is restricted by the component protective shell 3 and can only move up and down. The two sets of plane gears 5 can drive the two sets of bar gear plates 6 to work synchronously and drive the pressure top column 7 to move synchronously.

[0037] See also Figure 3 and Figure 6 The bar-shaped toothed plate 6 slides inside the component protective housing 3, and a flat worm gear 8 is fixedly provided on the outer circumference of the linkage bearing 4. The teeth on the outer circumference of the flat worm gear 8 are engaged with the threads on the outer circumference of the one-way worm 9. The close fit between the flat worm gear 8 and the one-way worm 9 can effectively transmit force and change the direction of force transmission, so that subsequent components can move normally. An external control disk 10 is fixedly provided at one end of the one-way worm 9, and the one-way worm 9 rotates inside the component protective housing 3. The setting of the external control disk 10 makes it convenient for the staff to drive the one-way worm 9 to rotate.

[0038] Working principle: Place the raw material at the position of the shaping groove 19 on the lower die 18, control the pressure component 1 to operate, drive the upper die 11 together with the shaping protrusion 12 and the clamping guide column 13 to descend, the clamping guide column 13 first contacts the specified position of the lower die 18, the shaping protrusion 12 contacts the raw material, and under the continuous pressure of the pressure component 1, the raw material is deformed, and the shaping protrusion 12 and the shaping groove 19 cooperate to obtain the mechanical arm assembly. When the thickness of the forging flash needs to be adjusted, the external control disk 10 is rotated by external force, driving the one-way worm 9 to move in the component protection The outer shell 3 rotates in place, causing the flat worm gear 8 to drive the linkage bearing 4 to rotate in place in the component protective shell 3. Under the restriction of the component protective shell 3, the strip tooth plate 6 drives the pressure top column 7 to rise. When stamping again, the strip tooth plate 6 will enter the L-shaped protective shell 14 and contact with the limit ring 15, causing the pressure top column 7 to lift the sealing top plate 17 and slide in the L-shaped protective shell 14, thereby making the sealing top plate 17 contact with the sensor 2. At this time, the toughness spring 16 is in a compressed state, and the sensor 2 sends a command signal to the pressure component 1 to control the pressure component 1 to no longer apply pressure, thereby adjusting the thickness of the forging flash.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
