Description

Technical Field

[0001] This invention relates to a shelf welding process and equipment, belonging to the field of shelf welding technology. Background Technology

[0002] Bicycle racks are used for the centralized transport of bicycles. There are several types, including trailer racks and quick-release racks. Trailer racks are small, independent trailers that connect bicycles via hooks. They are suitable for long-distance travel or transporting large items (such as camping equipment) and can bear a weight of over 50 kilograms. Quick-release racks can be installed / disassembled without tools and are suitable for temporary use, but their stability is slightly less than that of fixed racks.

[0003] For bicycle rack welding, the following processes can be selected: arc welding: suitable for high-strength welding of steel racks, but thermal deformation needs to be controlled; spot welding: suitable for quick assembly of light racks, but should be used with caution for load-bearing parts. The welding of uprights and beams should be full welding or reinforced fillet welding. It is recommended to add reinforcing plates to load-bearing nodes; anti-detachment welding structure (such as welded stop plates) should be designed for the shelf support parts.

[0004] Shelf welding is the process of assembling shelves by welding metal rods. Bicycle shelves require welding of side frames, front frames, and related accessories. The welding positions are numerous and complex, making it difficult to operate efficiently and quickly, which affects welding efficiency. Furthermore, it is difficult to precisely control each welding position during welding, resulting in errors that affect subsequent assembly welding, reduce the dimensional accuracy of the finished shelf, and may even lead to problems in subsequent welding, thus reducing the construction precision of the shelf.

[0020] A shelf welding process, the welding process comprising the following steps:

[0021] (1) Fixing the side frame components: Place the rods that make up the side frame in the placement area on the bonding plate, rotate the bolt against the pressure plate and push it close to the bonding plate, so that when the connecting rod moves inside the long hole, it drives the rotating plate to rotate. The rotating plate drives the pressure rod to press the rods into the placement area to achieve stable fixation.

[0022] (2) Welding of side frame accessories: Welding of fixed rods, foot plates and other parts. After completion, adjust the spacing between rods, start the drive device to drive the double screw to rotate. The transmission of pulley and belt realizes the synchronous rotation of the two double screws. The double screw drives the slider to move in the groove and drives the bonding plate to move synchronously. Adjust the position of the rods on the bonding plate to achieve size matching. Place the guard rod between the rods for welding and form, and weld the reflector and other accessories in the corresponding position.

[0023] (3) Forming the noodle frame: Adjust the position of the two side uprights so that the crossbars that make up the noodle frame overlap on the platform. Start the cylinder to drive the clamping rod to rotate around the connector. The clamping rod clamps the crossbars on the platform to complete the fixation. Then weld the longitudinal rods and other accessories on the platform. After completion, the noodle frame is obtained.

[0024] (4) The face frame is conveyed by driving the vertical screw to rotate through the drive motor, which in turn drives the movable plate to move in the vertical hole, thereby lifting the face frame. After reaching the designated position, the face frame is pushed flat onto the support plate. After the face frame welding is completed in sequence, face frames of different heights are conveyed.

[0025] (5) Welding of the face frame: Start the lifting hydraulic cylinder to drive the support plate to move. The cooperation of the guide block and the guide hole improves the stability of the support plate movement. Reinforcing ribs are set to improve the structural strength of the support plate. Adjust the face frame to an appropriate height to match the shelf spacing. Then start the translation hydraulic cylinder to push or move on the track, driving the side frame welded on the bonding plate to correspond with the face frame. Then weld the corresponding position.

[0026] (6) After the shelving is removed and the welding is completed, first loosen the bolts to separate the pressure bar from the side frame rod. Then start the drive device to make the pressure bar move to both sides and separate from the rod. At this time, the shelving is supported by multiple support plates. Finally, start the horizontal push hydraulic cylinder to drive the shelving on the support plate away from the bottom plate. The cooperation of the stabilizing rod and the sleeve plate improves the stability of movement. Then the lifting hydraulic cylinder shortens to make the shelving fall. The support plate continues to move horizontally to completely separate it from the shelving. Then the shelving is removed for subsequent shelving welding operations.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0028] The positive and progressive effects of this invention are as follows:

[0029] The aforementioned shelving welding process and equipment utilizes an assembly for shelving welding. With pre-assembled components, simultaneous welding of side frames and front panels is achieved, effectively improving welding efficiency. During welding, adjustments to the positions of corresponding members allow for positional adjustments, enhancing welding precision. This enables the welding of shelving of different sizes. After front panel welding, multi-layer panels are supported and positioned, with adjustments made according to the shelving layer spacing. The precise alignment between the front panel and side frames is achieved through the translation of uprights, improving subsequent welding accuracy and overall shelving welding efficiency. Furthermore, the horizontal pushing of supporting uprights facilitates shelving removal, enabling convenient positioning and welding of subsequent shelving components and enhancing the overall processing efficiency of the shelving welding equipment.

7. A shelf welding process using the shelf welding equipment as described in any one of claims 1-6, characterized in that: The welding process includes the following steps: (1) Fixing the side frame components: Place the rods that make up the side frame in the placement area (209) on the bonding plate (201), rotate the bolt (213) against the pressure plate (211) and push it close to the bonding plate (201), so that when the connecting rod (210) moves inside the elongated hole (212), it drives the rotating plate (207) to rotate. The rotating plate (207) drives the pressure rod (208) to press the rods into the placement area (209) to achieve stable fixation; (2) Welding of side frame accessories: Welding of foot plate fixing rods and foot plate parts for fixed rods. After completion, adjust the spacing between rods and start the drive device (206) to drive the double screw (203) to rotate. The transmission of pulley (204) and belt (205) realizes the synchronous rotation of the two double screws (203). The double screw (203) drives the slider (202) to move in the groove (107) and drives the bonding plate (201) to move synchronously. Adjust the position of the rods on the bonding plate (201) to achieve size matching. Place the guard rod between the rods for welding and form, and weld the reflector accessories at the corresponding positions. (3) Forming the noodle frame: Adjust the position of the two side uprights (106) so that the crossbars that make up the noodle frame overlap on the platform (405). Start the cylinder (407) to drive the clamping rod to rotate around the connector (409). The clamping rod clamps the crossbar on the platform (405) to complete the fixation. Then weld the longitudinal rods and other accessories on the platform (405). After completion, the noodle frame is obtained. (4) The noodle frame is conveyed by driving the vertical screw (403) to rotate through the drive motor (410), so that the vertical screw (403) drives the movable plate (404) to move in the vertical hole (402) to lift the noodle frame. After reaching the designated position, the noodle frame is pushed flat onto the support plate (307). After the noodle frame welding is completed in sequence, the noodle frames of different heights are conveyed. (5) Welding of the face frame: Start the lifting hydraulic cylinder (310) to drive the support plate (307) to move. The cooperation of the guide block (308) and the guide hole (306) improves the stability of the movement of the support plate (307). And set the reinforcing rib (309) to improve the structural strength of the support plate (307). Adjust the face frame to an appropriate height to match the shelf spacing. Then start the translation hydraulic cylinder (105) to push or move on the track (103) to drive the side frame welded on the bonding plate (201) to correspond with the face frame. Then weld the corresponding position. (6) After the shelf is removed and welded, first loosen the bolts (213) to separate the pressure bar (208) from the side frame rod. Then start the drive device (206) to make the pressure bar (208) move to both sides and separate from the rod. At this time, the shelf is supported by multiple support plates (307). Finally, start the horizontal hydraulic cylinder (311) to drive the shelf on the support plate (307) away from the bottom plate (101). The cooperation of the stabilizer bar (304) and the sleeve plate (111) improves the stability of movement. Then the lifting hydraulic cylinder (310) shortens to make the shelf fall. The support plate (307) continues to move to completely separate it from the shelf. Then the shelf is removed for subsequent shelf welding operations.
