Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub production blank forging, in particular to a wheel hub production blank forging device. Background Art

[0002] In the production of wheel hubs, billet forging is a core and critical manufacturing link, which directly determines the basic mechanical properties, internal structural integrity and initial forming of the final shape of the wheel hub.

[0003] During the forging process of the wheel hub production blank, the blank will be exposed to the air when transferred, which will add oxide scale. The friction between the die and the blank during forging may cause the oxide layer to peel off, and then the initial oxide scale generated by heating needs to be removed to avoid pressing into the forging. If the oxide layer is not completely cleaned, it will cause micro cracks to remain on the surface of the wheel hub production blank after processing, which will affect the safety of the wheel hub production blank in the later use. In addition, the traditional forging oxide layer is cleaned manually, which not only increases the cleaning intensity of the operator, but also increases the risk of burns for the operator.

[0004] For this reason, a wheel hub production blank forging device is needed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 In this embodiment, a wheel hub production blank forging device includes a base 1, with support vertical blocks 2 fixedly installed on the left and right sides of the top of the base 1 for support, and a forging press 3 is fixedly installed on the top surfaces of the two support vertical blocks 2. The top surface of the base 1 is located below the press 3 and is provided with a placement bottom die 4 for placement, and a gas supply assembly 5 for gas supply is provided at the back of the base 1. The interiors of the two support vertical blocks 2 are provided with gas guide cavities 6 for gas guide, and the two gas guide cavities 6 are provided with gas guide assemblies 7 for gas guide.

[0025] The air guide assembly 7 includes a plurality of air outlets 701 opened at the lower front side of the inner wall of the air guide cavity 6, and a blocking hole plate 702 for blocking is fixedly installed on the rear side of the lower inner wall of the air guide cavity 6, and the inner wall of the air guide cavity 6 is located above the blocking hole plate 702 and is fixedly connected to two sealing plates 703. The circumferential sides of the two blocking hole plates 702 are fixedly connected to the inner wall of the air guide cavity 6, and the top surface of the blocking hole plate 702 is fixedly connected to the bottom surface of the sealing plate 703 on the rear side. The two opposite sides of the sealing plate 703 are slidably mounted with overlapping orifice plates 704 for overlapping ventilation. The two blocking orifice plates 702 are both orifice plates with circular holes, and the inner walls of the two overlapping orifice plates 704 are both orifice plates with rectangular holes. The width of the inner wall of the overlapping orifice plate 704 is the same as the diameter of the inner wall of the blocking orifice plate 702. When the overlapping orifice plate 704 with rectangular holes and the blocking orifice plate 702 with circular holes are in contact with each other, better gas flow can be ensured. The top surfaces of the two corresponding overlapping orifice plates 704 are jointly fixed with a T-shaped connecting rod 705 for connection, and the inner wall of the air guide chamber 6 is provided with a sliding vertical opening 706 for sliding on one side of the T-shaped connecting rod 705. The opposite ends of the T-shaped connecting rod 705 extend to the surface of the supporting vertical block 2 through the inner wall of the corresponding sliding vertical opening 706, and the end of the T-shaped connecting rod 705 close to the press 3 is fixedly connected to the output end of the press 3. The T-shaped connecting rod 705 can ensure that when the press 3 is pressed down, it also drives the overlapping orifice plate 704 to move. The lower sides of the inner walls of the two air guide chambers 6 and the bottom surfaces of the corresponding front side sealing plates 703 are jointly fixed with a limiting vertical rod 8 for limiting, and the rear side of the limiting vertical rod 8 slides in contact with the front side of the overlapping orifice plate 704. The setting of the limiting vertical rod 8 can ensure the stability of the up and down movement of the overlapping orifice plate 704.

[0026] The air outlet 701 in this device is set at an angle, and the inclination direction is that the side close to the bottom mold 4 is lower than the side away from the bottom mold 4. In this way, the inclined air outlet 701 when viewed from above can better ensure the cleaning effect of the inside of the bottom mold 4, because the inclined jet flow of the air outlet 701 can generate a tangential force along the surface, which helps to place loose dirt, debris or waste inside the bottom mold 4, thereby avoiding the problem of cracks caused by the oxide layer adhering to the wheel hub blank, ensuring the safety of the wheel hub blank in later use, and avoiding the workload of manual cleaning by the operator, thereby avoiding the risk of burns to the operator due to cleaning the oxide layer, and increasing the overall safety of the device.

[0027] Among them, the gas delivery component 5 includes a storage shell 501 fixedly installed behind the base 1, and an air pump 502 for gas output is fixedly installed on the lower side of the inner wall of the storage shell 501, and an air guide pipe 503 for gas guidance is fixedly installed at the output end of the air pump 502, and two connecting pipes 504 for connection are fixedly installed above the surface of the air guide pipe 503. The upper ends of the two connecting pipes 504 pass through the upper side of the inner wall of the storage shell 501 and the back of the corresponding supporting vertical block 2, extending to the rear side of the inner wall of the corresponding air guide cavity 6, and a number of air permeable oblique openings 505 for ventilation are opened on the side of the inner wall of the storage shell 501 away from the base 1. The air permeable oblique openings 505 ensure the normal air extraction of the air pump 502, thereby ensuring the normal use function of the air pump 502.

[0028] The working principle of the above embodiment is:

[0029] During use of the device, the air pump 502, through the communication effect of the air guide pipe 503 and the connecting pipe 504, can ensure that a pressurized area is formed on the inner wall of the air guide cavity 6 behind the blocking orifice plate 702. This ensures that when the overlapping orifice plate 704 overlaps with the blocking orifice plate 702, the inner wall is penetrated, and the pressurized gas is discharged through the gas outlet 701, thereby blowing off and cleaning the oxide layer produced on the forging blank, thereby ensuring the quality of the forging of the wheel hub production blank;

[0030] When the press 3 moves downward, it not only ensures the forging of the hub production blank, but also drives the overlapping orifice plate 704 to move toward the blocking orifice plate 702 through the T-shaped connecting rod 705, thereby ensuring the overlap of the holes of the blocking orifice plate 702 and the overlapping orifice plate 704, and ensuring the effect of gas being blown out from the gas outlet 701, thereby cleaning the oxide layer during the forging process. When the press 3 is lifted, it will drive the overlapping orifice plate 704 and the blocking orifice plate 702 to move away from each other, thereby ending the blowing of the gas.

[0031] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
