Description

Technical Field

[0001] This application relates to the field of aluminum wheel hub production technology, and in particular to an aluminum rod cutting and fixing device for aluminum wheel hub production. Background Technology

[0002] Aluminum alloy automotive wheels are a type of automotive wheel made primarily of aluminum-silicon alloys. They are characterized by their light weight, rapid heat dissipation, and excellent shock absorption, and are widely used in passenger cars and racing vehicles. Their manufacturing processes include gravity casting, low-pressure casting, and spin forming. The main material is A356 aluminum alloy, containing elements such as aluminum, silicon, and magnesium. A balance between lightweight and high strength is achieved through structural design and process optimization.

[0003] In the production of aluminum wheel hubs, aluminum rods need to be cut. During the cutting process, the aluminum rods need to be fixed. However, ordinary fixing devices only use compression to fix the rods. When the aluminum rods are displaced, due to their relatively large mass, the frictional force during displacement is large, which wastes a lot of force. Therefore, we propose an aluminum rod cutting and fixing device for aluminum wheel hub production. Utility Model Content

[0004] This application provides an aluminum rod cutting and fixing device for aluminum wheel hub production to solve the problems mentioned above.

[0005] This application provides an aluminum rod cutting and fixing device for aluminum wheel hub production, comprising:

[0006] The base has a buffer displacement support plate and a compression fixing plate alternately arranged at its upper end. The lower end of the buffer displacement support plate is movably inserted into the limiting cavity that is opened at equal intervals in the base through a limiting plate. The lower end of the compression fixing plate is fixedly connected to the upper end of the base.

[0007] Limiting slide rods are equidistantly inserted through the left and right sides of the limiting plate. The limiting slide rods are fixedly connected to the upper and lower side walls of the limiting cavity, and a compression spring is sleeved on the outside of the limiting slide rod.

[0008] The upper middle part of the buffer displacement support plate and the compression fixing plate are respectively provided with a first semi-circular groove and a second semi-circular groove. The bottom inner side and the upper front and rear sides of the first semi-circular groove are rotatably embedded with rollers, and the front end of the central rotating shaft of the bottom roller is fixedly connected to a drive motor.

[0009] The upper end of the base is connected to a hydraulic cylinder via a support plate, and the lower end of the transmission rod of the hydraulic cylinder is fixedly connected to a pressure plate.

[0010] Preferably, the left end of the base is provided with a cutting area.

[0011] Preferably, the upper front and rear sides of the base are fixedly connected to a support plate by a support plate, and a hydraulic cylinder is fixedly connected to the middle of the upper left and right sides of the support plate.

[0012] Preferably, the pressure plate is arranged vertically opposite to the first semicircular groove and the second semicircular groove, and the lower end of the pressure plate is provided with an arc groove.

[0013] Preferably, the buffer displacement support plate has a motor mounting slot on the upper side of the middle part, and the drive motor is fixedly connected inside the motor mounting slot.

[0014] Preferably, the inner wall of the first semicircular groove is higher than the inner wall of the second semicircular groove.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art:

[0016] The structure provided in this application embodiment, when the drive motor is started, drives the rollers at the bottom to rotate, thereby driving the upper aluminum rod to move to the left. After the position reaches the set position, the drive motor stops running. Then, the hydraulic cylinder is started, causing the hydraulic cylinder to drive the pressure plate to move downward, thereby squeezing the upper end of the aluminum rod. This causes the aluminum rod to move downward, so that the lower end of the aluminum rod is squeezed and pressed against the upper end of the pressing and fixing plate. Thus, the aluminum rod is squeezed and fixed by the upper extrusion force, making the fixing and displacement of the aluminum rod more convenient and faster. Attached Figure Description

[0027] like Figures 1-4 As shown in the figure, this application provides an aluminum rod cutting and fixing device for aluminum wheel hub production, comprising:

[0028] The base 1 has a buffer displacement support plate 5 and a compression fixing plate 9 alternately arranged at its upper end. The lower end of the buffer displacement support plate 5 is movably inserted into the limiting cavity 13 that is equally spaced in the base 1 through a limiting plate 11. The lower end of the compression fixing plate 9 is fixedly connected to the upper end of the base 1.

[0029] Limiting slide rods 12 are equidistantly inserted through the left and right sides of the limiting plate 11. The limiting slide rods 12 are fixedly connected to the upper and lower side walls of the limiting cavity 13, and a compression spring 14 is sleeved on the outside of the limiting slide rods 12.

[0030] The upper middle part of the buffer displacement support plate 5 and the compression fixing plate 9 are respectively provided with a first semi-circular groove 8 and a second semi-circular groove 10. The bottom inner side and the upper front and rear sides of the first semi-circular groove 8 are rotatably embedded with rollers 7, and the front end of the central rotating shaft of the bottom roller 7 is fixedly connected to a transmission motor 15.

[0031] The upper end of the base 1 is connected to a hydraulic cylinder 4 via a support plate 3, and a pressure plate is fixedly connected to the lower end of the transmission rod of the hydraulic cylinder 4.

[0032] like Figure 1 As shown, the left end of the base 1 is provided with a cutting area 2.

[0033] Specifically: The aluminum rod exposed on the left side can be cut off by the cutting device set outside the cutting area 2.

[0034] like Figure 1 As shown, the upper front and rear sides of the base 1 are fixedly connected to the support plate 3 by the support plate, and the upper left and right sides of the support plate 3 are fixedly connected to the hydraulic cylinder 4.

[0035] Specifically: Hydraulic cylinder 4 adopts existing hydraulic cylinders on the market, which is existing technology. Hydraulic cylinder 4 drives the pressure plate to move up and down.

[0036] like Figure 1 As shown, the pressure plate is arranged vertically opposite to the first semicircular groove 8 and the second semicircular groove 10, and the lower end of the pressure plate is provided with an arc groove.

[0037] Specifically, the downward displacement of the pressure plate can compress and fix the aluminum rod placed inside the first semicircular groove 8 and the second semicircular groove 10.

[0038] like Figure 2 and Figure 4 As shown, a motor mounting slot 6 is opened on the upper side of the middle part of the buffer displacement support plate 5, and the transmission motor 15 is fixedly connected inside the motor mounting slot 6.

[0039] Specifically: The drive motor 15 uses an existing motor on the market, which is existing technology. The drive motor 15 is used to drive the bottom roller 7 to rotate.

[0040] like Figure 2 As shown, the inner wall of the first semicircular groove 8 is higher than the inner wall of the second semicircular groove 10.

[0041] Specifically: aluminum rods are placed inside the first semicircular groove 8 and the second semicircular groove 10.

[0042] Principle: When the equipment is in use, the elastic coefficient of the compression spring 14 needs to be limited so that the aluminum rod being cut is placed inside the first semicircular groove 8 and the lower end of the aluminum rod does not come into contact with the second semicircular groove 10.

[0043] When placing the aluminum rod, the drive motor 15 will start and drive the rollers 7 at the bottom to rotate, thereby driving the upper aluminum rod to move to the left. After the position reaches the set position, the drive motor 15 will stop running.

[0044] Then, the hydraulic cylinder 4 is activated, causing the pressure plate to move downward, thereby squeezing the upper end of the aluminum rod. This causes the aluminum rod to move downward, so that the lower end of the aluminum rod is squeezed and pressed against the upper end of the pressing and fixing plate 9. Thus, the aluminum rod is squeezed and fixed by the upper squeezing force. Then, the aluminum rod exposed on the left side can be cut off by the cutting device set outside the cutting area 2.

[0045] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
