Description

Technical Field

[0001] The utility model belongs to the technical field of rear axle half-shaft production, and specifically relates to forging equipment for rear axle half-shaft production. Background Art

[0002] The rear axle refers to the rear drive shaft component of a vehicle's power transmission. It consists of two half-axles, enabling half-axle differential motion. It also serves as a device for supporting and connecting the wheels. Rear axle half-axles undergo forging during the actual processing process, including rough forging, axle body forming forging, and end flange forging. During the end flange forging process, the forging blank needs to be inserted and installed in a forging mold. Because the forging mold and forging hammer correspond vertically, and the half-axles have specific length specifications, placing and removing the forging blank is relatively inconvenient. For longer half-axles, sufficient space for placement and removal requires large-scale forging equipment, which increases production investment.

[0003] In view of this, the present utility model is proposed. Utility Model Content

A die support seat 2 is fixedly installed on the main frame 1, and a forging die body 3 is matched with the die support seat 2. Connecting side plates 8 are fixedly installed on both sides of the forging die body 3. A through hole 11 is processed on the connecting side plate 8. A through hole 11 is penetrated and installed in the through hole 11. A support plate 14 is provided at the lower end of the through hole 12. The bottom surface of the support plate 14 is fixedly connected to the upper end of a telescopic rod 15. The lower end of the telescopic rod 15 is fixedly provided with a lower connecting seat 16. The lower connecting seat 16 is fixedly provided with a lower connecting seat 16. The seat 16 is rotatably connected to the rotating support seat 17, and the rotating support seat 17 is fixedly mounted on the main frame 1. A hinge seat 19 is fixedly provided on the outer side of the telescopic rod. The hinge seat 19 is rotatably connected to one end of the connecting rod 20, and the other end of the connecting rod 20 is rotatably connected to the connecting end 21. The connecting end 21 is fixedly mounted on the end position of the telescopic rod 22. The end of the telescopic rod 22 away from the connecting end 21 is fixedly mounted on the support frame 23, and the support frame 23 is fixedly mounted on the main frame 1. Corresponding slots 4 for taking and placing materials are provided on the mold support seat 2 and the main frame 1.

[0024] Among them, a forging hammer 7 is provided directly above the mold support seat 2, and the forging hammer 7 is installed at the lower end of the forging power box 6. The upper end of the forging power box 6 is fixedly mounted on the upper bracket 5, and the upper bracket 5 is fixedly mounted on the main frame 1. The forging power box 6 uses a hydraulic cylinder or a pneumatic cylinder.

[0025] A rotation limit block 18 is fixedly provided on one side of the rotation support seat 17 close to the support frame 23, which is used to limit the rotation of the telescopic rod 15 so that it rotates to a vertical state. The support frame 23 is a T-shaped structure with good supporting stability.

[0026] A mounting hole is provided at the center of the die support seat 2 . The outer dimensions of the forging die body 3 match the mounting hole of the die support seat 2 . The die support seat 2 is used to effectively support the forging die body 3 .

[0027] The upper end of the penetration column 12 is installed with a limiting nut 13 through a threaded connection. The distance between the bottom surface of the limiting nut 13 and the top surface of the support plate 14 is greater than the thickness of the connecting side plate 8. The limiting nut 13 is used to limit the connecting side plate 8 to prevent the connecting side plate 8 from loosening and separating from the penetration column 12 during rotation and adjustment.

[0028] A fixed base 9 is integrally provided at the bottom of the mold support seat 2 , and the fixed base 9 is fixedly connected to the main frame 1 via fixing screws 10 .

[0029] The working principle of the present invention is as follows: when the end flange of the rear axle half shaft is forged, the telescopic rod 22 is started, and during the extension process of the telescopic rod 22, the connecting rod 20 pushes the telescopic rod 15 to rotate along the rotating support seat 17, driving the forging die body 3 to rotate outward to an inclined state, and dislocating the forging hammer 7 (as shown in the attached figure). Figure 3 As shown), the axle blank of the rear axle half shaft is then placed in the forging die main body 3, with the shaft end of the half shaft facing downward. After placement, the telescopic rod 22 is retracted, driving the telescopic rod 15 and the forging die main body 3 to rotate. The side of the rotating support seat 17 is provided with a rotation limit block 18 for rotating the telescopic rod 15. The side of the lower connecting seat 16 contacts the positioning surface of the rotation limit block 18 for limiting the position. The telescopic rod 15 is in a vertical state, and the upper plane of the forging die main body 3 is in a horizontal state. The telescopic rod 15 is retracted, causing the forging die main body 3 to fall and be installed in the die support seat 2, completing the placement of the forging blank. Then, the power device in the forging power box 6 is started to drive the forging hammer 7 to move back and forth to forge the blank;

[0030] After the forging process is completed, the telescopic rod 15 is extended to push the forging die body 3 out of the die support seat 2. Then the telescopic rod 22 is started, and the telescopic rod 22 and the forging die body 3 are driven to rotate through the connecting rod 20. The forged half shaft is removed from the forging die body 3 and the next blank is placed.

[0031] Telescopic rod 15 and telescopic rod 22 are electric telescopic rods, which are electrically connected to an external power supply. The forging power box 6 is equipped with corresponding supporting devices to ensure the realization of the function.

[0032] The forging die main body 3 of the present invention is fixedly provided with connecting side plates 8 on both sides, and the connecting side plates 8 are equipped with a rotation adjustment and lifting adjustment mechanism, which can drive the forging die main body 3 to rotate a certain angle and stagger the position with the forging hammer 7 to avoid interference in the process of placing or removing the forging blank, and can effectively reduce the lifting height of the forging hammer 7 and reduce the volume of the equipment. Corresponding slots 4 for taking and discharging materials are correspondingly provided on the main frame 1 and the die support seat 2. After the forging blank is placed in the forging die main body 3, the position of the forging die main body 3 is adjusted without being affected by the half-shaft main body. The forging equipment can meet the forging processing and use requirements of half-shafts of different specifications and has good adaptability.
