Description

Technical Field

[0001] This invention relates to the field of hub processing equipment, specifically to an integrated automatic hub forming machine. Background Technology

[0002] Hubs are a core component of wheelsets in bicycles, electric vehicles, and other vehicles, and their manufacturing quality directly affects the smoothness of wheel rotation and service life. The manufacturing of hubs typically involves multiple processes, including reaming, edge bending, edge trimming, punching, internal chamfering, and boring.

[0003] Traditional processing methods use multiple independent machines to complete each process separately. The workpiece needs to be repeatedly transferred and re-clamped between different machines, which is not only inefficient, but also prone to positioning deviations due to multiple clamping, affecting processing accuracy.

[0004] Furthermore, different diameter hubs require different molds and fixtures, resulting in poor versatility of existing equipment. While existing automated processing equipment has seen some improvements, most processes are fragmented, with each process such as reaming, bending, trimming, and punching requiring its own independent drive unit, leading to high equipment costs and large floor space requirements. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated automatic forming machine for flower drums, thereby solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated automatic hub forming machine, comprising a frame and a pipe feeding machine. The frame is sequentially equipped with a multi-mold forming mechanism, a first transfer robot, an inner chamfering mechanism, a second transfer robot, a third transfer robot, and a boring mechanism. Hub positioning and clamping assemblies are fixedly connected to the frame at the multi-mold forming mechanism, the inner chamfering mechanism, and the boring mechanism. Each of the multi-mold forming mechanism, the inner chamfering mechanism, and the boring mechanism has two units. A material feeding slide rail is fixedly connected to the frame between the inner chamfering mechanism and the boring mechanism. The multi-mold forming mechanism includes a two-axis moving module and a mold base plate. A positioning plate, a hole-expanding mold, a folding mold, a trimming mold, and a punching mold are detachably connected to the side of the mold base plate. The hub positioning and clamping assembly includes a positioning carrier and a clamping cylinder. A pressure plate is detachably connected to the output end of the clamping cylinder. The positioning carrier is detachably connected to the frame.

[0007] Furthermore, the inner chamfering mechanism includes a chamfering translation cylinder and a chamfering punch. The chamfering translation cylinder is fixedly connected to the frame, and the chamfering punch is fixedly connected to the piston rod of the chamfering translation cylinder.

[0008] Furthermore, the boring mechanism includes a boring translation cylinder, a power head, and a boring tool. The boring translation cylinder is fixedly connected to the frame, the power head is fixedly connected to the piston rod of the boring translation cylinder, and the boring tool is fixedly connected to the rotating end of the power head.

[0009] Furthermore, the frame is provided with a stamping waste collection channel at the processing position of the multi-mold forming mechanism, and the frame is provided with a boring waste collection channel at the boring mechanism.

[0010] Furthermore, the boring waste collection channel has multiple oil leakage holes arranged in an array on the boring waste collection channel, and an oil baffle plate is fixedly connected to the tail end of the boring waste collection channel. An oil tank is provided on the frame below the boring waste collection channel.

[0011] Furthermore, the output ends of the first, second, and third transfer manipulators are all fixedly connected to gripper cylinders, and positioning cylinders are detachably connected to the grippers of the gripper cylinders.

[0012] Furthermore, the unloading slide rail is inclined on the frame, with one end of the unloading slide rail near the boring mechanism being lower than the other end, and a baffle is fixedly connected to the end of the unloading slide rail near the boring mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-mold forming mechanism (expansion, bending, trimming, punching), the inner chamfering mechanism and the boring mechanism are integrated into the same equipment, and the workpiece is automatically transferred between each station by the first transfer robot, the second transfer robot and the third transfer robot, realizing the integrated automatic processing of the hub from the tube blank to the finished product, improving production efficiency and processing accuracy.

[0014] In the multi-mold forming mechanism, the positioning plate, expanding die, bending die, trimming die, and punching die are all mounted on the die base plate and driven by the same two-axis moving module. This allows the four processes of expanding, bending, trimming, and punching to share a single drive unit, effectively reducing equipment costs and floor space. The dies are detachable, so only the dies need to be replaced to adapt to different specifications of hubs, making it highly versatile.

[0015] The stamping waste collection channel and the boring waste collection channel collect waste separately for classification. The oil leakage hole on the boring waste collection channel can separate the cutting fluid from the metal chips. The cutting fluid flows into the oil tank for recycling and reuse, while the metal chips are discharged along the channel, realizing the classification and recycling of cutting fluid and waste, which is energy-saving and environmentally friendly.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example:

[0023] according to Figures 1-4 The diagram shows an integrated automatic forming machine for flower drums, comprising a frame and a pipe feeder 1. The frame, serving as the support structure for the entire machine, is welded from structural steel to ensure sufficient rigidity and stability. The pipe feeder 1 is a lifting-type feeder used to arrange the pipe blanks into an orderly arrangement and output them one by one.

[0024] The frame is sequentially equipped with a multi-mold forming mechanism 2, a first transfer robot 3, an internal chamfering mechanism 4, a second transfer robot 5, a third transfer robot 6, and a boring mechanism 7. "Sequentially" refers to their arrangement from front to back along the processing flow direction of the tubular blank. There are two of each of the multi-mold forming mechanism 2, the internal chamfering mechanism 4, and the boring mechanism 7, located on either side of the hub processing position, for simultaneous processing of both ends of the hub.

[0025] Hub positioning and clamping assemblies 8 are fixedly connected to the multi-mold forming mechanism 2, the inner chamfering mechanism 4, and the boring mechanism 7 on the frame. The hub positioning and clamping assembly 8 includes a positioning carrier 801 and a clamping cylinder 802. The output end of the clamping cylinder 802 is detachably connected to a pressure plate 803. The positioning carrier 801 is detachably connected to the frame and can be replaced to accommodate hubs of different specifications.

[0026] The multi-mold forming mechanism 2 includes a two-axis moving module 201 and a mold base plate 202. The two-axis moving module 201 can drive the mold base plate 202 to move in the horizontal plane along the X and Y axes. The mold base plate 202 is detachably connected to a positioning plate 203, a hole-expanding mold 204, a bending mold 205, a trimming mold 206, and a punching mold 207. The molds are arranged sequentially along the moving direction of the mold base plate 202, and different molds are switched to the processing position by moving the two-axis moving module 201.

[0027] The inner chamfering mechanism 4 includes a chamfering translation cylinder 401 and a chamfering punch 402. The chamfering translation cylinder 401 is fixedly connected to the frame, and the chamfering punch 402 is fixedly connected to the piston rod of the chamfering translation cylinder 401. The chamfering translation cylinder 401 drives the chamfering punch 402 to chamfer the intersection of the folded edge and the straight tube of the hub semi-finished product.

[0028] The boring mechanism 7 includes a boring translation cylinder 701, a power head 702, and a boring tool 703. The boring translation cylinder 701 is fixedly connected to the frame, the power head 702 is fixedly connected to the piston rod of the boring translation cylinder 701, and the boring tool 703 is fixedly connected to the rotating end of the power head 702. The power head 702 drives the boring tool 703 to rotate, and the boring translation cylinder 701 pushes the power head 702 to feed, thus boring both ends of the semi-finished hub.

[0029] A stamping waste collection channel 12 is provided on the frame at the processing position of the multi-die forming mechanism 2 to collect waste generated during the punching process. A boring waste collection channel 13 is provided on the frame at the boring mechanism 7. Multiple oil drain holes are arranged in an array on the boring waste collection channel 13. An oil baffle plate 14 is fixedly connected to the tail end of the boring waste collection channel 13. An oil tank 15 is provided on the frame below the boring waste collection channel 13. The cutting fluid and metal chips generated during boring fall onto the boring waste collection channel 13. The cutting fluid flows into the oil tank 15 through the oil drain holes for recycling, while the metal chips slide down the channel and are discharged.

[0030] The output ends of the first transfer robot 3, the second transfer robot 5, and the third transfer robot 6 are all fixedly connected to gripper cylinders 10, and positioning cylinders 11 are detachably connected to the grippers of the gripper cylinders 10. The positioning cylinders 11 can be replaced to accommodate hubs of different diameters.

[0031] A material discharge slide rail 9 is fixedly connected to the frame between the inner chamfering mechanism 4 and the boring mechanism 7. The material discharge slide rail 9 is inclined on the frame, with one end of the material discharge slide rail 9 closer to the boring mechanism 7 being lower than the other end. A baffle is fixedly connected to the end of the material discharge slide rail 9 closer to the boring mechanism 7. The semi-finished hub is placed on the material discharge slide rail 9 by the second transfer robot 5 from the inner chamfering mechanism 4, slides down to the baffle by gravity and stops, and is then picked up by the third transfer robot 6 and transferred to the boring mechanism 7.

[0032] The working principle of this invention is as follows:

[0033] The pipe fitting blank is fed by the pipe fitting feeder 1. During processing, the first transfer robot 3 picks up the pipe fitting from the discharge end of the pipe fitting feeder 1 and transfers it to the positioning carrier 801 at the multi-mold forming mechanism 2. Subsequently, the multi-mold forming mechanism 2 on both sides of the positioning carrier 801 performs processing: the two-axis moving module 201 first drives the positioning plate 203 to move and insert into the inner hole of the pipe fitting for positioning, then the clamping cylinder 802 drives the pressure plate 803 to press the pipe fitting down, and then the positioning plate 203 resets; the two-axis moving module 201 drives the hole-expanding mold 204 to expand the holes at both ends of the pipe fitting; after the hole expansion is completed, the two-axis moving module 201 drives the edge-folding mold 205 to flatten and bend the beveled edges of the expanded holes at both ends of the pipe fitting; then the two-axis moving module 201 drives the edge-trimming mold 206 to punch the edge; finally, the two-axis moving module 201 drives the punching mold 207 to punch the edge.

[0034] After the processing at the multi-mold forming mechanism 2 is completed, the clamping cylinder 802 at the multi-mold forming mechanism 2 drives the pressure plate 803 to reset. The first transfer robot 3 transfers the semi-finished hub to the positioning carrier 801 at the inner chamfering mechanism 4. The clamping cylinder 802 at this location drives the pressure plate 803 to clamp the hub. The piston rods of the chamfering translation cylinders 401 on both sides extend and drive the chamfering punch 402 to chamfer the intersection of the folded edge and the straight tube of the semi-finished hub.

[0035] After the chamfering is completed, the clamping cylinder 802 at this location resets. The second transfer robot 5 picks up the semi-finished product from the positioning carrier 801 at the inner chamfering mechanism 4 and transfers it to the unloading slide rail 9. The semi-finished product slides along the inclined unloading slide rail 9 and finally stops at the baffle. The third transfer robot 6 moves to the end of the unloading slide rail 9, picks up the semi-finished product, and transfers it to the positioning carrier 801 at the boring mechanism 7. The clamping cylinder 802 at this location drives the pressure plate 803 to clamp the hub, and the boring mechanisms 7 on both sides perform boring treatment on both ends of the hub semi-finished product. After processing is completed, the clamping cylinder 802 resets and releases the clamp, and the third transfer robot 6 picks up the finished product for unloading.
