Description

Technical field:

[0001] The utility model relates to the technical field related to wheel hub processing equipment, and more specifically to a side mold quenching device for an aluminum alloy wheel hub mold. Background technology:

[0002] The casting wheel hub mold generally includes a side mold, a top mold and a bottom mold, wherein the four side molds are basically combined to form a ring body, and the top and bottom ends of the top mold, the bottom mold and the side mold correspond to each other;

[0003] Among them, the wall where the top of the side mold connects to the top mold is a position prone to wear. Due to the need to close and open the mold, this position is very easy to wear. Generally, it will wear out after a certain number of productions. Later, it is easy for aluminum to stick to the worn area and corrode, and then produce flash, which affects the casting and machining efficiency. In severe cases, aluminum may escape.

[0004] Moreover, the products after flashing need to be processed manually, which is very troublesome and requires a lot of manual labor. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a side mold quenching device for an aluminum alloy wheel hub mold, which can quench the bottom surface and side walls of the arc-shaped groove on the upper part of the side mold to improve its hardness, thereby reducing the wear caused by mold closing and mold opening between it and the top mold, improving processing accuracy, reducing the generation of flash, and improving durability.

[0023] For example, see Figures 1 to 4 As shown, a side mold quenching device for an aluminum alloy wheel hub mold comprises a high-frequency quenching main machine 10 (this is a product directly purchased on the market and will not be described in detail) and a water tank main body 20. A bottom support seat 30 is provided below the high-frequency quenching main machine 10, and an adjustment mechanism 40 for adjusting the left and right movement of the high-frequency quenching main machine 10 is installed on the bottom support seat 30;

[0024] The adjusting mechanism 40 includes a vertical plate 41 fixed to the left part of the top surface of the bottom support seat 30, a transverse adjusting screw 42 screwed into a screw-connected through hole in the middle of the vertical plate 41, a right end of the transverse adjusting screw 42 extends out of the right side wall of the vertical plate 41 and is movably connected to the left side wall of the high-frequency quenching main machine 10 through a bearing, a left end of the transverse adjusting screw 42 extends out of the vertical plate 41 and is fixed with a rotating wheel 43, a locking nut 44 is screwed onto the transverse adjusting screw 42, and an end face of the locking nut 44 is tightly against the side wall of the vertical plate 41.

[0025] A plurality of sliding blocks 13 are fixed on the bottom surface of the high-frequency quenching main machine 10 , and a plurality of guide rails 101 are fixed on the top surface of the bottom support seat 30 .

[0026] A scale plate 2 is fixed to the left portion of the top surface of the bottom support seat 30 , and the top surface of the scale plate 2 corresponds to the left side wall of the high-frequency quenching main machine 10 .

[0027] When the adjustment mechanism 40 is used, the locking nut 44 can be loosened and then the lateral adjustment screw 42 can be rotated, so that the sliding block 13 of the high-frequency quenching host 10 can move left and right along the guide rail 101. After moving to the specified position of the scale plate 2, the locking nut 44 can be loosened, which is very convenient.

[0028] Furthermore, the water tank body 20 is located on the right side of the bottom support seat 30, and the upper part of the left side plate of the water tank body 20 is formed with an upwardly extending extension plate portion 26, the quenching sensor head connecting rod 11 is inserted into the through hole of the extension plate portion 26, and the right end of the quenching sensor head connecting rod 11 extends out of the right side wall of the through hole of the extension plate portion 26.

[0029] Furthermore, a rotating base 21 is fixed to the middle of the top surface of the bottom plate of the water tank body 20, and the rotating base 21 is movably connected to the main rotating shaft 22 through a bearing. The top of the main rotating shaft 22 extends out of the rotating base 21, and an upper rotating connecting plate is fixed to the top surface of the rotating connecting plate at the top of the main rotating shaft 22. A working platform 50 is fixed to the top surface of the upper rotating connecting plate. The lower part of the main rotating shaft 22 is in the rotating base 21 and is fixed with a transmission gear 23. A driving motor 24 is fixed on the inner side wall of the side plate of the rotating base 21, and a driving gear 25 is fixed on the output shaft of the driving motor 24, and the driving gear 25 is meshed with the transmission gear 23.

[0030] Among them, a threading hole is formed on the side plate of the rotating base 21, which can insert the electrical connection line of the driving motor 24 into the threading hole, and a sealing material is filled between the threading hole and the electrical connection line for sealing. The end of the electrical connection line of the driving motor 24 extends out of the threading hole and is electrically connected to the external control host, and the operation is controlled by the control host. The lower side wall of the water tank body 20 is connected with a drainage connector 1, and the drainage connector 1 can be connected to the cooling water return connection pipe, and the cooling water return connection pipe can be connected to the water storage tank to prevent excessive water in the water tank body 20.

[0031] A side mold 100 to be processed is installed on the top surface of the working platform 50 , and a quenching induction head 12 fixed on the quenching induction head connecting rod 11 of the high-frequency quenching main machine 10 is close to the bottom surface and inner wall of the arc groove formed on the inner wall of the top end of the corresponding side mold 100 .

[0032] The working platform 50 is a long plate, and limit blocks 51 are fixed at the middle of the top surface of the front and rear parts;

[0033] The limit block 51 includes two left and right oblique long strips 511. The rear ends of the two oblique long strips 511 of the front limit block 51 are formed together and the front ends are separated. The front ends of the two oblique long strips 511 of the rear limit block 51 are formed together and the rear ends are separated. The rear end of the front limit block 51 is close to the front end of the rear limit block 51 and is located at the central axis of the middle part of the working platform 50. Among the four oblique long strips 511, each adjacent two oblique long strips 511 form an angle of 90°.

[0034] The left and right parts of the top surface of the working platform 50 are both fixed with horizontal positioning guide strips 52 extending left and right, and the horizontal positioning guide strip 52 and an adjacent oblique long strip block 511 form an angle of 45 degrees.

[0035] When this structure is in use, the side mold 100 can be lifted and placed on the left and right parts of the top surface of the working platform 50, and its transverse positioning guide bar 52 can be inserted into the long groove in the middle of the bottom surface of the side mold 100. Then, the side mold 100 is moved so that the wall surfaces at both ends are tightly attached to the inner side walls of the corresponding oblique long strips 511 to achieve positioning and pressing.

[0036] A vertical screw hole is formed at the central axis of the middle of the working platform 50, and the vertical screw hole corresponds to and communicates with the arc-shaped notches formed at the ends of the two limit blocks 51;

[0037] This structure allows the bottom surface of the center positioning rod 53 to be pressed against the top surfaces of the ends of the two limit blocks 51 when the high-frequency quenching main unit 10 is assembled for the first time in this embodiment, and the screw connection portion formed in the middle of the bottom surface of the center positioning rod 53 is inserted into the corresponding arc-shaped notch and screwed into the vertical screw connection hole. Then, check whether the central axis of the center positioning rod 53 is aligned with the quenching sensor head 12 and the quenching sensor head connecting rod 11, that is, they are on the same vertical plane. If they are not aligned, move the high-frequency quenching main unit 10 and the bottom support seat 30. This center positioning rod 53 is used to facilitate the alignment of the equipment assembly. After the first assembly is completed, it does not need to be used later.

[0038] When this embodiment is in use, the side mold 100 to be processed is lifted by a crane and placed on the right part of the top surface of the working platform 50, and its transverse positioning guide strip 52 is inserted into the long groove in the middle of the bottom surface of the side mold 100. Then, the side mold 100 is moved so that its two end walls are closely attached to the inner side walls of the corresponding oblique long strip 511 to achieve positioning and pressing, and the installation is completed. Then, the working platform 50 is rotated horizontally by driving the motor 24. When it is rotated for the first time, it is necessary to check the side mold 100 during rotation. The matching state of the arc groove at the top and the quenching induction head 12 is generally observed when the quenching induction head 12 is used. When the two do not match, the locking nut 44 needs to be loosened, and then the lateral adjustment screw 42 is rotated to realize the left and right movement of the high-frequency quenching host 10, thereby changing the left and right positions of the quenching induction head 12, so that the two match, and the scale on the top surface of the scale plate 2 facing the left side wall of the high-frequency quenching host 10 is the adjusted scale position, and then the locking nut 44 can be loosened, which is convenient for adjustment;

[0039] As for the coordination problem between the height of the arc groove at the top of the side mold 100 and the quenching sensor head 12, it can be adjusted by fixing a pad on the bottom surface of the side mold 100. Of course, the height of most side molds 100 is basically the same, and only the side molds 100 for some particularly small wheel hub processing need to be raised and adjusted.

[0040] After the adjustment is completed, processing can be carried out. The high-frequency quenching host 10 is turned on and the driving motor 24 is operated, so that the quenching induction head 12 quenches the bottom surface and side walls of the side mold 100 along the arc groove. During the quenching process, a water spray pipe can be set outside close to the quenching induction head 12 to cool it. The water will finally be in the water tank body 20 and discharged through the drainage connector 1. The quenching process increases the hardness of the bottom surface and side walls of the arc groove, which can generally reach more than 50 degrees, thereby reducing the wear caused by the clamping and demolding between it and the top mold, improving the processing accuracy, reducing the generation of flash, and improving the durability of use.

[0041] At the same time, a first sealing sleeve 2 is fixed to the lower part of the side wall of the upper rotating connecting plate, an inner sealing sleeve 3 is fixed to the top surface of the rotating base 21, and the lower inner wall of the first density sleeve 2 is tightly attached to the outer wall of the inner density sleeve 3, so as to prevent water from entering the rotating base 21 during rotation.
