Description

Technical Field

[0001] This invention relates to the field of metal toy frame processing, and more particularly to a metal toy frame and its processing technology. Background Technology

[0002] Metal toy display frames are a common type of toy display support device, widely used in shopping malls, exhibition halls, and warehouse displays. Their main function is to provide a stable support structure for the displayed products through a combination of fixed plates, supports, and brackets.

[0003] Chinese Patent CN120206080A discloses a metal fitting display rack processing and welding device and method, comprising an electric slide rail fixedly mounted on the top of a base beam, a mounting base disposed at the sliding end of the electric slide rail and arranged perpendicularly to the base beam, and a movable through slot opened on the top of the mounting base for vertical movement of a steel pipe. The mounting base has an adjustment mechanism on its side wall, which includes a fixed base. The side wall of the fixed base is movably provided with a positioning mechanism extending to the top of the mounting base for clamping the steel pipe. This invention utilizes the adjustment components of the positioning mechanism and the positioning plate to enable the positioning plate to clamp and position rectangular and circular steel pipes, facilitating subsequent welding of different display racks. Furthermore, the connecting mechanism facilitates the disassembly and assembly of the positioning mechanism, allowing it to be removed from the mounting base for maintenance, thus simplifying practical operations such as repair and replacement.

[0004] Existing metal toy display frames mostly use manual welding to assemble and weld the fixing plates, support rods and limiting plates. During the welding process, it is often necessary to manually adjust the position and angle of the workpiece repeatedly, resulting in insufficient weld precision, large positional deviation, and quality problems such as limiting plates falling off or the embedded disc not rotating smoothly.

[0035] Please see Figure 2 The auxiliary welding device includes a plane adjustment mechanism 1 for adjusting the horizontal position of the workpiece. An angle adjustment mechanism 2 is connected to the top of the plane adjustment mechanism 1. The angle adjustment mechanism 2 can adjust the tilt angle and circumferential angle of the workpiece during the welding process. A push cylinder 3 is connected to the lower right side of the plane adjustment mechanism 1. The push cylinder 3 can adjust the left and right position of the workpiece being welded.

[0036] Please see Figures 3-5The planar adjustment mechanism 1 includes a support plate 11 for support. A transmission box 12 is located at the lower right bottom of the support plate 11. A first motor 13 is located at the lower right end of the transmission box 12. A fixing frame 14 is fixed to the bottom of the transmission box 12. A transmission gear 15 is connected to the lower left end of the fixing frame 14. A follower 16 is connected to the outside of the transmission gear 15. The inside of the follower 16 has a tooth that meshes with the outside of the transmission gear 15. The middle part of the follower 16 is connected to the bottom of the support plate 11 through a connecting rod 17. The middle part of the bottom end of the follower 16 is connected to a sliding plate through a connecting rod 18. Plate 19 and slide plate 19 are movably embedded in the guide member 110. The bottom right end of the guide member 110 is protruding and is movably embedded in the guide groove 111. The lower end of the fixing frame 14 is L-shaped and is fixed to the bottom of the guide groove 111. The front and rear ends of the middle part of the fixing frame 14 extend out. The extended position is convenient for limiting the follower 16. The lower right end of the fixing frame 14 is connected to the push rod of the push cylinder 3. The bottom of the fixing frame 14 can be connected to the external guide component to facilitate the overall displacement under the force of the push cylinder 3.

[0037] The right end of the transmission box 12 is provided with a drive pulley 12a that is connected to the output shaft of the first motor 13. The outer side of the drive pulley 12a rotates synchronously with the driven pulley 12c through a synchronous belt 12b.

[0038] Please see Figure 6 The angle adjustment mechanism 2 includes a base 21 for support and fixed to the bottom of the support plate 11. The top of the base 21 has two protrusions near the middle. A second motor 22 is installed at the right end of the top of the base 21, and a third motor 23 is installed at the left end of the top. The output shaft of the second motor 22 is connected to a transmission shaft 24.

Locking holes are provided at both ends of the support plate 28 to facilitate the connection of external clamps to fix the workpiece.

[0039] The specific steps of a metal toy frame manufacturing process are as follows:

[0040] S1. Based on design requirements, stainless steel plates and rods meeting strength and corrosion resistance requirements are selected. The plates are used to process the fixing plate a, the rods are used to process the support rods c and brackets g, and the thin sheet is used for the limiting plate f. Simultaneously, stamped parts are prepared as blanks for the embedded disc e. All materials undergo visual inspection before processing to ensure no obvious cracks, oxidation, or warping. S2. Through holes b and circular grooves d are created on the metal plates using a stamping process. The dimensions of the circular groove d must precisely match the embedded disc e to ensure its rotational function. After processing, the fixing plate a is ground and deburred, and then leveled to ensure flatness and structural accuracy. S3. The embedded disc e is processed by stamping and... A locking hole is made in the middle. The edge of the embedded plate e needs to be polished smooth to avoid jamming or damage during assembly. After processing, the diameter of the embedded plate e and the position of the locking hole need to be checked to ensure that they are aligned with the circular groove d and the through hole b to ensure the display function. S4 Cut the metal rod to the designed length and chamfer or grind the ends to facilitate subsequent welding. The support rod c is used to connect the two sets of fixed plates a, and the bracket g is welded to the bottom of the fixed plate a to provide support. This step must ensure dimensional accuracy to ensure the stability of the overall frame. S5 Cut the metal sheet into an arc-shaped limiting piece f and grind the edges to avoid burrs that would obstruct the rotation of the embedded plate e. The size of the limiting piece f must match the circular groove d and the through hole b of the fixed plate a. S6. The fixing plate a is placed on the support plate of the auxiliary welding device and fixed with a clamp. The horizontal and left and right positions are adjusted by the plane adjustment mechanism and the push cylinder, and the tilt and circumferential angle are adjusted by the angle adjustment mechanism. After debugging, the device can provide precise positioning and stable support for the pre-welding and repair welding of the limit piece f. S7. First, the pre-welding of the limit piece f is completed by the auxiliary welding device to ensure that it is in a stable state at the corresponding position of the circular groove d. Then, the two sets of fixing plates a are placed opposite each other and welded to the four-end support rods c to form a frame. After the pre-welding of the limit piece f is completed, the auxiliary welding device is started. The angle and position adjustment functions are set, and the limiting piece f is welded to improve the weld strength. Finally, the bracket g is welded to the bottom of the fixed plate a to form an overall load-bearing structure. S8 The processed embedding plate e is embedded one by one into the circular groove d of the fixed plate a, so that it can rotate freely under the constraint of the limiting piece f. Check whether the card hole and the through hole b are aligned to ensure that the product can be smoothly inserted and fixed without jamming or displacement when it is displayed. S9 After the overall welding is completed, the weld is ground and repaired, and then the entire iron frame is degreased, derusted and shot blasted. Then, an electrophoretic coating process is used to improve the corrosion resistance and enhance the appearance, ensuring its long-term performance.

[0041] The specific implementation process of the auxiliary welding device is as follows:

[0042] When welding the limiting piece f, the entire fixing plate a needs to be placed on top of the support plate 28 and then fixed by an external clamp. The limiting pieces f can then be placed manually or by an external robot. A corresponding welding device is needed above the support plate 28 before work begins.

[0043] When position adjustment is required, the push cylinder 3 is activated to push the plane adjustment mechanism 1, which can move left and right. The first motor 13 is started to work, and the first motor 13 drives the active pulley 12a to rotate. During the rotation of the active pulley 12a, the synchronous belt 12b drives the driven pulley 12c to rotate. The shaft in the middle of the driven pulley 12c causes the transmission gear 15 to rotate. During the rotation of the transmission gear 15, the follower 16 can be moved. The lower end of the follower 16 acts on the slide plate 19 through the connecting rod 18. The slide plate 19 and the guide 110 cooperate and the guide groove 111 guides, so that the support plate 11 above the follower 16 can perform a cyclical movement of a racetrack-shaped trajectory. The welding device can then start welding the limiting pieces f one by one to the fixed plate a.

[0044] After all the pre-welded limit plates f are completed, the third motor 23 can be started. During the operation of the third motor 23, the swinging component 27 can cause the driven bevel gear 26 to tilt the support plate 28. This is coordinated with the start of the second motor 22. The second motor 22 drives the transmission shaft 24 to make the driving bevel gear 25 rotate the driven bevel gear 26, thereby adjusting the support plate 28 to the optimal tilt position. This can then be coordinated with the synchronous operation of the plane adjustment mechanism 1 and the push cylinder 3 to allow the external welding device to perform supplementary welding on the pre-welded limit plates f. After the welding is completed, the next set of fixed plates a is replaced to continue the welding work.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
