Technical Field

[0001] The utility model relates to the technical field of rear axle production, in particular to a forging device for producing a heavy truck rear axle half-axle. Background Art

[0002] The rear axle refers to the rear drive shaft component for vehicle power transmission. It consists of two half-bridges and can implement half-bridge differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels. The rear axle half-axles need to be forged during the elongation process.

[0003] Basic forging equipment generally uses a lifting method to lift the forged material to the top, but due to the fixed forging stroke, it is not possible to easily remove the material when forging higher materials, which has certain limitations. In order to solve the above technical problems, we have designed a forging equipment for the production of heavy-duty truck rear axle half-axles. Utility Model Content

[0004] The purpose of the utility model is to provide a forging equipment for the production of heavy-duty truck rear axle half-axles, which has the advantage of convenient material removal and solves the problem that basic forging equipment generally uses a lifting method to lift the top of the forged material, but due to the fixed forging stroke, it is impossible to conveniently remove the material when forging higher materials, which has certain limitations.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a forging device for producing heavy-duty truck rear axle half-axles, comprising a base plate, a bracket fixedly connected to the left side of the top of the base plate, a hydraulic cylinder installed on the top bolt of the bracket, an upper mold installed on the output end of the hydraulic cylinder, a displacement groove is provided on the top of the base plate, a movable displacement component is installed through the inner cavity of the displacement groove, the movable displacement component comprises a mounting seat, a block and a multi-section electric telescopic rod, a lower mold is installed on the top bolt of the mounting seat, and a tooth plate is installed on the output end of the multi-section electric telescopic rod.

[0006] Preferably, the displacement groove is adapted to the mounting seat, and a convex shaft is fixedly connected to the right side of the top of the mounting seat.

[0007] Preferably, the top of the convex shaft passes through the top of the bottom plate and is fixedly sleeved with a gear, which is engaged with the gear plate.

[0008] Preferably, a T-shaped block is fixedly connected to the rear side of the bottom of the tooth plate, and a T-shaped slot for use with the T-shaped block is opened on the top of the bottom plate.

[0009] Preferably, there are two stoppers, which are symmetrically distributed on the top of the base plate, and the bottom of the stoppers is fixedly connected to the top of the base plate.

[0018] See also Figure 3 , the displacement groove 6 is adapted to the mounting seat 201, and the right side of the top of the mounting seat 201 is fixedly connected with a convex shaft 206. By setting the convex shaft 206, it can be installed through the base plate 1, so that the mounting seat 201 can rotate around the convex shaft 206 and meet the fixed installation requirements of the gear 207;

[0019] See also Figure 3 The top of the convex shaft 206 passes through the top of the bottom plate 1 and is fixedly sleeved with a gear 207. The gear 207 is meshed with the tooth plate 203. By setting the tooth plate 203 and the gear 207, a meshing transmission can be achieved. When the tooth plate 203 moves forward and backward, the gear 207 will rotate forward and reverse.

[0020] See also Figure 3 The rear side of the bottom of the tooth plate 203 is fixedly connected with a T-block 204, and the top of the bottom plate 1 is provided with a T-slot 208 used in conjunction with the T-block 204. By setting the T-block 204 and the T-slot 208, it can play a role in positioning and guiding, and can effectively ensure the stability of the front and rear movement of the tooth plate 203;

[0021] See also Figure 3 There are two stoppers 209, which are symmetrically distributed on the top of the bottom plate 1. The bottom of the stopper 209 is fixedly connected to the top of the bottom plate 1. By setting the stopper 209, it can contact the positioning block 205 when the mounting seat 201 is in the installation state or the unloading state, so as to avoid excessive rotation displacement of the mounting seat 201 and meet the requirements of the inlay installation of the electromagnet 210.

[0022] See also Figure 3 , the front surface of the stopper 209 is fixedly inlaid with an electromagnet 210, and the right side of the top of the mounting seat 201 is fixedly connected with a positioning block 205, which is adapted to the electromagnet 210;

[0023] The positioning block 205 is made of 440C stainless steel, which has the characteristics of high hardness, oxidation resistance, corrosion resistance and magnetic attraction, and can cooperate with the electromagnet 210 in the energized state to prevent the mounting base 201 from rotating randomly;

[0024] Auxiliary blocks are installed on the fixed end and the output end of the multi-section electric telescopic rod 202. The auxiliary block at the fixed end is fixedly connected to the top of the base plate 1, and the auxiliary block at the output end is fixedly connected to the tooth plate 203. Therefore, when the multi-section electric telescopic rod 202 is telescopic, the tooth plate 203 can be synchronously displaced forward and backward.

[0025] When in use, all components are in the initial installation state. When the positioning block 205 is aligned with the left stopper 209, the corresponding electromagnet 210 is controlled to be energized, and the positioning block 205 is magnetically attracted to ensure the position stability of the mounting seat 201. At this time, the hydraulic cylinder 3 is controlled to extend to work, so that the upper mold 8 can be moved down and well matched with the lower mold 5 to forge the rear axle half shaft. After forging is completed, the hydraulic cylinder 3 is first controlled to move the upper mold 8 up and reset, and the electromagnet 210 on the left is powered off. Then the multi-section electric telescopic rod 202 is controlled to retract. With the assistance of the T-block 204 and the T-slot 208, the tooth plate 203 is stably moved forward, and then the gear 207 is rotated counterclockwise, synchronously causing the cam 206 and the mounting seat 201 to rotate until the positioning block 205 contacts the right stopper 209, and the corresponding electromagnet 210 is controlled to be energized to ensure the position stability of the mounting seat 201. At this time, there is no obstacle above the lower mold 5, which is conducive to the staff taking out the processed materials.

[0026] To sum up: the forging equipment for the production of heavy-duty truck rear axle half-axles, by setting up a movable displacement component 2 and a displacement slot 6, solves the problem that basic forging equipment generally uses a lifting method to move the top of the forged material, but due to the fixed forging stroke, when forging higher materials, it is impossible to easily remove the material, which has certain limitations.
