Description

Technical Field

[0001] The invention relates to the technical field of automobile wheel hub forging, in particular to an automobile wheel hub forging hydraulic press. Background Art

[0002] A wheel hub is a cylindrical metal component mounted on an axle, supporting the tire's inner profile. It's also called a rim, wheel, wheel, or wheel rim. Wheels come in a wide variety of shapes, depending on their diameter, width, molding method, and material. During production, wheels are typically stamped and forged using a hydraulic press, ensuring both aesthetics and production efficiency. With the advancement of modern technology, the functionality and structure of hydraulic presses used in automotive wheel forging have been continuously refined, making them even more convenient to use.

[0003] However, existing automobile wheel forging hydraulic presses do not have the function of positioning and fixing wheels with different gears during the stamping process. Traditional hydraulic presses rely on the mold cavity for passive positioning. When processing special-shaped wheels or products with variable diameters, the blank is prone to multi-directional stress offset. If there is any slight offset, the steel plate used for the entire wheel processing will be lost and cannot be used further. At the same time, it is very inconvenient to disassemble and assemble the molds for wheels with different patterns, which reduces the overall production efficiency.

[0004] In addition, during the operation of the existing wheel hub forging hydraulic press, there is no function to remove dust particles on the surface of the blank, so that the stamping and forging with dust particles attached will seriously affect the smoothness of the wheel hub surface and the overall quality of the wheel hub;

[0005] In this regard, this design proposes a hydraulic press for forging automobile wheels to solve the above technical problems. Summary of the Invention

[0006] The object of the present invention is to provide a hydraulic press for forging automobile wheels to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned objectives, the present invention proposes a hydraulic press for forging automobile wheel hubs, comprising a hydraulic press base, a hydraulic cylinder, a lifting platen, and a quick-release positioning mechanism, a dust cleaning mechanism, and a reset assembly, all of which are mounted on the hydraulic press base and distributed inside and outside. The hydraulic cylinder is mounted on the top of the hydraulic press base, and the output end of the hydraulic cylinder passes through the inner wall of the hydraulic press base and is fixedly connected to the top of the lifting platen, and the lifting platen is slidably connected to the outer wall of the hydraulic press base.

[0008] The quick-release positioning mechanism includes a first mounting groove provided at the lower end of the inner wall of the hydraulic press base, a second mounting groove provided on the inner wall of the hydraulic press base above the first mounting groove, a first gear rotatably connected to the middle position of the bottom of the inner wall of the second mounting groove, three second gears rotatably installed on the edge of the inner wall of the second mounting groove, and the outer wall of each second gear is respectively engaged with the outer wall of the first gear, a support shaft is fixedly provided at the edge of the top of each second gear, and the top of each support shaft is connected to a positioning plate by a screw, a first motor is installed on the inner wall of the first mounting groove, and one end of the first gear is fixedly connected to the output end of the first motor, a clip is fixedly provided at the middle position of the top of the hydraulic press base, a mold disk is installed at the middle position of the top of the hydraulic press base, a slot is provided at the bottom of the mold disk, and the outer wall of the clip is interlaced with the inner wall of the slot, three arc-shaped through-grooves are equidistantly provided on the top of the hydraulic press base and the top of the mold disk, and the outer wall of one end of each support shaft is respectively interlaced with the inner walls of two of the arc-shaped through-grooves.

[0009] In one example, the dust cleaning mechanism includes a gear ring mounted on the top of the hydraulic press base, an outer wall of the gear ring is meshed with a third gear, and the third gear is rotatably mounted on the upper edge of the inner wall of the hydraulic press base.

[0010] In one example, a support seat is fixedly provided on one side of the top of the gear ring, a high-pressure air gun is installed on the top of the support seat, a third mounting groove is opened on the inner wall of the hydraulic press base at the outer edge of the second mounting groove, a second motor is installed on the inner wall of the third mounting groove, and one end of the third gear passes through the inner wall of the third mounting groove and is fixedly connected to the output end of the second motor.

[0011] In one example, a gas tank is installed on one side of the outer wall of the hydraulic press base, a conduit is inserted into one end of the gas tank, and one end of the conduit is connected to the inner wall of one end of the high-pressure air gun. An annular groove is provided at the outer edge of the mold plate at the top of the hydraulic press base, and the gear ring rotates on the inner wall of the annular groove.

[0012] In one example, the reset assembly includes a positioning tube fixedly mounted on one side of the outer wall of the hydraulic press base, a gravity ball is inserted into the inner wall of the positioning tube, and a connecting ring is fixedly connected to the top of the gravity ball.

[0013] In one example, guide rings are fixedly provided on both sides of the top of the positioning tube, and the outer wall of the catheter is respectively connected to the inner walls of the two guide rings and the inner wall of the connecting ring.

[0014] In one example, a punching plate is fixedly provided at the middle position of the bottom of the lifting plate, and the height of the punching plate when contacting the top of the hydraulic press base is higher than the top of the support seat.

[0015] In one example, a control panel is installed on one side of the hydraulic press base, and the first motor, the second motor and the high-pressure air gun are all electrically connected to an external power supply through the control panel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a quick-release positioning mechanism, when positioning the blank, the meshing rotation of the first gear and the second gear causes the three positioning plates on the die plate to quickly approach or move away from the blank under the drive of the support shaft, thereby achieving rapid positioning and clamping of different blanks. At the same time, when it is necessary to replace the die plate with a different pattern, it is only necessary to unscrew the screws fixed between the positioning plate and the support shaft to disassemble and replace it. This solves the problems of the lack of positioning function in the hydraulic press for forging automobile wheel hubs in actual use, which easily leads to the deviation of the blank stamping position, increased loss costs, and low processing efficiency caused by inconvenient die disassembly and assembly;

[0018] 2. By setting up a dust cleaning mechanism, after the blank is positioned and installed, and before it is stamped and forged, the second motor is started so that the gear ring, under the meshing of the third gear, carries the support seat and the high-pressure air gun to perform reciprocating circular motion around the blank. The high-pressure air gun is connected to the air tank for high-pressure blowing, thereby completely blowing away the particles and dust on the surface of the blank, avoiding the uneven surface of the hub or even potholes caused by the influence of particles and dust during stamping, thereby improving the forging quality of the hub;

[0019] 3. By setting a reset component, each time the high-pressure air gun on the cleaning mechanism performs reciprocating circular motion, the catheter moves arbitrarily and is pulled, and the catheter passes through the guide ring on the positioning tube for pulling. When the high-pressure air gun blows away the dust and returns to its original position, the catheter is pulled into the positioning tube under the gravity of the gravity ball and the connecting ring, so that it will not be entangled on the top of the hydraulic press base, avoiding damage by pulling. At the same time, there is no need for staff to manually organize the catheter frequently, thereby improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0031] See also Figure 1-8 The present invention provides a technical solution: a hydraulic press for forging automobile wheel hubs, comprising a hydraulic press base 1, a hydraulic cylinder 2, a lifting platen 3, and a quick-release positioning mechanism 4, a dust cleaning mechanism 5, and a reset assembly 6, all of which are mounted on the hydraulic press base 1 and distributed inside and outside. The hydraulic cylinder 2 is mounted on the top of the hydraulic press base 1, and the output end of the hydraulic cylinder 2 passes through the inner wall of the hydraulic press base 1 and is fixedly connected to the top of the lifting platen 3, and the lifting platen 3 is slidably connected to the outer wall of the hydraulic press base 1.

[0032] The quick-release positioning mechanism 4 includes a first mounting groove 401 provided at the lower end of the inner wall of the hydraulic press base 1, a second mounting groove 402 is provided on the inner wall of the hydraulic press base 1 above the first mounting groove 401, a first gear 403 is rotatably connected to the middle position of the bottom of the inner wall of the second mounting groove 402, three second gears 404 are rotatably installed at the edge of the inner wall of the second mounting groove 402, and the outer wall of each second gear 404 is respectively meshed with the outer wall of the first gear 403, a support shaft 405 is fixed to the edge of the top of each second gear 404, and the top of each support shaft 405 is connected to a positioning plate 406 by a screw, a first motor 407 is installed on the inner wall of the first mounting groove 401, and one end of the first gear 403 is fixedly connected to the output end of the first motor 407. Then, a buckle 408 is fixedly provided at the middle position of the top of the hydraulic press base 1, and a mold disk 409 is installed at the middle position of the top of the hydraulic press base 1. A slot 410 is provided at the bottom of the mold disk 409, and the outer wall of the buckle 408 is connected with the inner wall of the slot 410. Three arc-shaped through grooves 411 are provided at equal distances on the top of the hydraulic press base 1 and the top of the mold disk 409, and the outer wall of one end of each support shaft 405 is connected with the inner walls of two of the arc-shaped through grooves 411. When the mold disk 409 is installed on the hydraulic press base 1, it is fixed with the slot 410 at its bottom and the buckle 408, so that the support shaft 405 moves with the positioning disk 406 without moving with the mold disk 409, thereby ensuring the stability of the mold disk 409 during the stamping process.

[0033] When in use, the corresponding mold plate 409 is docked and engaged with the buckle 408 on the top of the hydraulic press base 1 through the slot 410 at the bottom thereof as needed, and when the mold plate 409 is installed, the arcuate slot 411 at the upper end thereof is aligned with the arcuate slot 411 at the top of the hydraulic press base 1, so that the three support shafts 405 are respectively inserted through the arcuate slots 411 to expose the top of the mold plate 409, and then the positioning plate 406 is placed on the top of the support shaft 405 and screwed in, as shown in the attached manual. Figure 1As shown, a wheel hub blank is placed on the top of the die plate 409, and then the first motor 407 in the first mounting slot 401 is started to drive the first gear 403 to rotate, thereby engaging the three second gears 404 at the edge to rotate and simultaneously driving the support shaft 405 installed at the edge of the three second gears 404 to move, so that the movement trajectory of the support shaft 405 is consistent with the shape of the arc-shaped through slot 411, thereby driving the positioning plate 406 to move closer to or away from the center area on the top of the die plate 409 to clamp and fix wheel hub blanks of different sizes. After the wheel hub is forged, the first motor 407 is used to drive the first gear 403 to rotate in the opposite direction again to move the positioning plate 406 away from the blank, thereby releasing the fixation. At the same time, when replacing the die plate 409, it is only necessary to unscrew the screws fixed between the positioning plate 406 and the support shaft 405 to replace it. This solves the problems in the prior art that the automobile wheel hub forging hydraulic press has no positioning function, which easily leads to the offset of the blank stamping position, increases the loss cost, and the mold is inconvenient to disassemble and assemble, resulting in low processing efficiency.

[0034] Further, as the instructions Figure 6 As shown, the dust cleaning mechanism 5 includes a gear ring 501 installed on the top of the hydraulic press base 1, and the outer wall of the gear ring 501 is meshed with a third gear 502, and the third gear 502 is rotatably mounted on the upper edge of the inner wall of the hydraulic press base 1. The area where the third gear 502 is mounted on the upper edge of the inner wall of the hydraulic press base 1 has a space sufficient for the third gear 502 to rotate therein, and the area is connected to the inner wall of one end of the annular chute 509, so that the third gear 502 is meshed with the gear ring 501 through the communication area;

[0035] Further, as the instructions Figure 7 As shown, a support base 503 is fixedly provided on one side of the top of the gear ring 501, and a high-pressure air gun 504 is installed on the top of the support base 503. A third mounting groove 505 is provided on the inner wall of the hydraulic press base 1 at the outer edge of the second mounting groove 402. A second motor 506 is installed on the inner wall of the third mounting groove 505, and one end of the third gear 502 passes through the inner wall of the third mounting groove 505 and is fixedly connected to the output end of the second motor 506. When the second motor 506 drives the third gear 502 to rotate and engages the gear ring 501 to rotate, the second motor 506 is a servo motor, which drives the third gear 502 to rotate reciprocatingly by reciprocating drive, and then drives the gear ring 501 and the support base 503 at its upper end to rotate reciprocally on the hydraulic press base 1 to avoid the conduit 508 from being entangled due to excessive rotation.

[0036] A gas tank 507 is installed on one side of the outer wall of the hydraulic press base 1, and a conduit 508 is inserted and connected to one end of the gas tank 507, and one end of the conduit 508 is communicated with the inner wall of one end of the high-pressure air gun 504. An annular groove 509 is provided on the outer edge of the mold plate 409 at the top of the hydraulic press base 1, and the gear ring 501 rotates on the inner wall of the annular groove 509. After the blank is placed on the mold plate 409 for positioning and clamping, the high-pressure air gun 504 is started and the gas tank 507 is opened to guide the air flow and blow it to the upper surface of the blank at high pressure to blow away the dust particles on the surface. Under the meshing transmission of the gear ring 501 and the third gear 502, the high-pressure air gun 504 reciprocates around the blank, thereby blowing away the dust and metal around it, avoiding the occurrence of potholes on the surface of the hub due to the extrusion of hard solid particles during the later stamping, thereby improving the processing quality of the hub.

[0037] Furthermore, the reset assembly 6 includes a positioning tube 601 fixedly mounted on one side of the outer wall of the hydraulic press base 1, the inner wall of the positioning tube 601 is connected with a gravity ball 602, the top of the gravity ball 602 is fixedly connected with a connecting ring 603, and the gravity ball 602 and the connecting ring 603 are both placed on the inner side of the positioning tube 601 so that they slide up and down in the inner wall of the positioning tube 601. The specific structural distribution is shown in the attached manual. Figure 8 shown.

[0038] The guide rings 604 are fixed on both sides of the top of the positioning tube 601, and the outer walls of the conduit 508 are respectively connected with the inner walls of the two guide rings 604 and the inner wall of the connecting ring 603. When the high-pressure air gun 504 on the cleaning mechanism 5 is meshed with the third gear 502 through the gear ring 501 and drives it to do reciprocating circular motion, the conduit 508 connecting the high-pressure air gun 504 and the gas tank 507 is also pulled and drawn accordingly. After each cleaning, the support seat 503 will rotate to its original position with the high-pressure air gun 504. At this time, under the pull of the gravity ball 602 and the connecting ring 603, the conduit 508 is pulled and contracted in the positioning tube 601, and will not be entangled and distributed on the hydraulic press base 1, thereby avoiding the pulling that causes the conduit 508 to break, thereby making the equipment unusable. At the same time, there is no need for the staff to manually store and organize the conduit 508 every time when cleaning, thereby improving the convenience of using the device.

[0039] Further, as the instructions Figure 9 As shown, a punching plate 7 is fixedly provided at the middle position of the bottom of the lifting plate 3, and the height of the punching plate 7 when contacting the top of the hydraulic press base 1 is higher than the top of the support seat 503. Since the height of the punching plate 7 when contacting the top of the hydraulic press base 1 is higher than the top of the support seat 503, when stamping and forging the wheel hub, the bottom of the lifting plate 3 will not squeeze the high-pressure air gun 504 and the support seat 503, thereby avoiding the equipment being crushed and damaged during stamping.

Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple. For the relevant parts, please refer to the partial description of the method embodiment.
