Description

Technical Field

[0001] This utility model relates to the field of wheelchair processing technology, and in particular to a material handling device for wheelchair frame production. Background Technology

[0002] Wheelchairs are crucial tools for people with disabilities, the elderly, and other mobility impairments, assisting them in achieving mobility. The wheelchair frame, as the core support structure, not only secures the wheels, seat, armrests, and other components but also bears the user's weight, making it a core component ensuring the overall stability and safety of the wheelchair. When using straight steel tubing as the base material for the wheelchair frame, specific bending treatments are required to fabricate ergonomic structures such as the seat frame, armrest curvature, footrest bend angle, and backrest curvature. This ensures the frame adapts to the user's seating needs and precisely matches the installation dimensions of the wheels, seat, and other components. In the process of bending steel tubes for wheelchair frames, if manual feeding is used, there will be problems such as low production efficiency, large deviation in bending accuracy, and high operational safety risks, which will seriously restrict the promotion of large-scale production.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1 Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a material handling device for wheelchair frame production. The material handling device for wheelchair frame production includes a main body component 1 and a material handling component 2. The two work together to facilitate the handling of steel pipes.

[0026] The main component 1 includes a bending machine 11, and a base 12 is provided at the bottom of the bending machine 11.

[0027] The bending machine 11 is a metal forming machine used to bend metal sheets into specific angles or shapes. The base 12 of the bending machine 11 is the supporting structure of the entire equipment. It is made of thick steel plates or high-strength cast iron, etc., to withstand the huge impact and vibration forces during the operation of the equipment, to ensure the stable operation of the equipment, and the levelness can be calibrated by adjusting the bolts. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0028] The material handling component 2 is located on one side of the bending machine 11 and includes a material handling element 21. The material handling element 21 includes a placement frame 211. A conveying roller 212 is provided on the inner wall of the placement frame 211. A placement groove 212-1 is opened on the inner wall of the conveying roller 212. A rotating shaft 213 is provided on the inner wall of the conveying roller 212. A sliding groove 213-1 is opened on the inner wall of the rotating shaft 213. A slider 214 is provided on the inner wall of the sliding groove 213-1. The other end of the slider 214 is fixed to the inner wall of the conveying roller 212.

[0029] A support column is also inserted into the inner wall of the conveyor roller 212. The other end of the support column is fixed to one end of the placement frame 211 to support the conveyor roller 212.

[0030] A conveyor belt is installed on one side of the bending machine 11 to transport the bent steel pipe.

[0031] First, the steel pipe needs to be fed into the inner wall of the placement frame 211. The steel pipe will fall onto the placement groove 212-1. Then, the movement of the rotating shaft 213 drives the slide 213-1 to squeeze the slider 214, causing the conveying roller 212 to rotate. The rotation of the conveying roller 212 drives the steel pipe to rotate, and the steel pipe will fall out. The steel pipe can then be bent by the subsequent structure.

[0032] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the material handling assembly 2 also includes a support member 22, which includes an extrusion plate 221 fixed to one end of the rotating shaft 213.

[0034] The extrusion plate 221 is extruded and moved. The movement of the extrusion plate 221 drives the rotation shaft 213 to move. The translation of the rotation shaft 213 can cause the conveying roller 212 to rotate. The rotation of the conveying roller 212 drives the steel pipe to rotate. At this time, the steel pipe will fall out. The steel pipe can be bent by subsequent structures through the falling steel pipe.

[0035] Specifically, a positioning shaft 222 is inserted into the inner wall of the extrusion plate 221. One end of the positioning shaft 222 is fixed to one end of the placement frame 211. A first spring 223 is sleeved on the outer side of the positioning shaft 222. One end of the first spring 223 is fixed to one end of the extrusion plate 221, and the other end is fixed to one end of the placement frame 211.

[0036] The positioning shaft 222 is used to support the extrusion plate 221 and prevent the extrusion plate 221 from rotating when moving. The extrusion plate 221 is extruded and moved. The movement of the extrusion plate 221 will pull the first spring 223. The movement of the extrusion plate 221 will drive the rotating shaft 213 to move. The translation of the rotating shaft 213 can cause the conveying roller 212 to rotate. The rotation of the conveying roller 212 will drive the steel pipe to rotate. At this time, the steel pipe will fall out. The steel pipe can be bent by the subsequent structure through the falling steel pipe.

[0037] Specifically, an extrusion strip 224 is provided on one side of the extrusion plate 221, and a sliding block 225 is fixed to one end of the extrusion strip 224.

[0038] Two extrusion strips are fixed at one end of the sliding block 225.

[0039] By moving the sliding block 225, the sliding block 225 causes the extrusion strip 224 to extrude the extrusion plate 221.

[0040] Specifically, a fixing frame 226 is fitted on the outer side of the sliding block 225, and the fixing frame 226 is fixed to one end of the base 12. A threaded rod 227 is inserted into the inner wall of the sliding block 225, and a motor 228 is provided at one end of the threaded rod 227.

[0041] The threaded rod 227 is inserted into the inner wall of the fixed frame 226 and rotates. The other end is fitted with a sleeve, one end of which is fixed to one end of the base 12 to support the threaded rod 227.

[0042] The sliding block 225 is threadedly connected to the threaded rod 227. The power of the motor 228 can drive the threaded rod 227 to rotate. The rotation of the threaded rod 227 causes the sliding block 225 to move. The movement of the sliding block 225 causes the extrusion strip 224 to extrude the extrusion plate 221. The movement of the extrusion plate 221 will pull the first spring 223, at which point the steel pipe will fall off.

[0043] Example 3 Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, the material handling component 2 also includes a positioning component 23, which includes a support frame 231 fixed to the bottom of the placement frame 211, with one end of the support frame 231 fixed to the top of the base 12.

[0045] The support frame 231 is used to support and place the steel pipe. When the steel pipe falls, it lands directly on the support frame 231. At this time, the movement of the sliding block 225 will squeeze the steel pipe to move it to the required position, and then bending can begin.

[0046] At this point, the bending is complete. The threaded rod 227 will continue to rotate for a while, causing the sliding block 225 to push the bent steel pipe again, so that the steel pipe falls onto the conveyor belt and can then be transported via the conveyor belt.

[0047] Specifically, two positioning blocks 232 are provided on one side of the support frame 231, and a pressing block 233 is fixed at the bottom of the positioning block 232.

[0048] The movement of the sliding block 225 causes the extrusion strip to extrude the extrusion block 233. One end of the extrusion block 233 is inclined. The movement of the extrusion block 233 causes the two positioning blocks 232 to move towards each other. The movement of the two positioning blocks 232 can position the steel pipe and prevent the steel pipe from shifting when bending.

[0049] Specifically, a positioning frame 234 is sleeved on the outside of the extrusion block 233, and a second spring 235 is fixed to one end of the extrusion block 233. One end of the second spring 235 is fixed to the inner wall of the positioning frame 234.

[0050] The movement of the sliding block 225 causes the extrusion strip to extrude the extrusion block 233. One end of the extrusion block 233 is inclined. The movement of the extrusion block 233 causes the two positioning blocks 232 to move towards each other. The movement of the extrusion block 233 pulls the second spring 235. The positioning frame 234 is a component used to support and guide the extrusion block 233. One end of the positioning frame 234 is fixed to the top of the base 12. After the bending work is completed, the sliding block 225 will cause the extrusion strip to separate from the extrusion block 233. At this time, the force of the rebound of the second spring 235 will cause the two positioning blocks 232 to return to their original positions for the next positioning.

[0051] Specifically, a slide bar 236 is fixed to one end of the extrusion block 233.

[0052] The movement of the compression block 233 drives the slide bar 236 to move.

[0053] Specifically, a positioning plate 237 is fitted on the outer side of the slide bar 236, and one end of the positioning plate 237 is fixed to the top of the base 12.

[0054] The movement of the extrusion block 233 causes the slide bar 236 to slide on the inner wall of the positioning plate 237. The slide bar 236 is used to support the extrusion block 233, making the extrusion block 233 more stable when moving.

[0055] In use, the steel pipe is placed into the placement frame 211, and the steel pipe naturally falls onto the placement groove 212-1 of the conveying roller 212, completing the initial placement. Then, the motor 228 is started, and the motor 228 drives the threaded rod 227 to rotate. The rotation of the threaded rod 227 causes the sliding block 225 to move along the fixed frame 226. The sliding block 225 simultaneously drives the extrusion strip 224 to move. The extrusion strip 224 first contacts the extrusion plate 221 and applies pressure to it, causing the extrusion plate 221 to translate along the positioning shaft 222, while stretching the first spring 223. The movement of the extrusion plate 221 causes the rotating shaft 213 to translate synchronously. The sliding groove 213-1 of the rotating shaft 213 squeezes the slider 214 on the inner wall of the conveying roller 212, causing the conveying roller 212 to rotate. At this time, the steel pipe will fall onto the support frame 231. Then, the threaded rod 227 will continue to rotate, and the rotation of the threaded rod 227 will drive the sliding block 225 to squeeze the steel pipe, so that the steel pipe moves to the required position for bending. The movement of the sliding block 225 will drive the extrusion strip 224 to contact and squeeze the extrusion block 233. The extrusion block 233 slides along the positioning frame 234 and stretches the second spring 235, while driving the sliding rod 236 to move stably within the positioning plate 237. The movement of the extrusion block 233 will cause the two positioning blocks 232 to move towards each other, clamping and positioning the steel pipe on the support frame 231 to prevent it from shifting during bending. At this time, the bending is completed. The threaded rod 227 will continue to rotate for a while, driving the sliding block 225 to push the bent steel pipe again, so that the steel pipe falls onto the conveyor belt, and then it can be transported by the conveyor belt.

[0056] After the steel pipe is bent, the motor 228 reverses to reset the sliding block 225, and the extrusion strip 224 separates from the extrusion plate 221 and the extrusion block 233; the first spring 223 rebounds to reset the extrusion plate 221 and the rotating shaft 213, and the conveying roller 212 returns to its initial state; the second spring 235 rebounds to reset the extrusion block 233 and the positioning block 232, releases the steel pipe, and waits for the next steel pipe to be fed, completing one cycle.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
