Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a high-efficiency pneumatic special machine for rolling pipe products. Background Technology

[0002] Currently, in the processing of metal pipe fittings, for parts that need to be rolled, mechanisms similar to pipe bending machines are often used. Due to the high investment in equipment, this puts a certain cost pressure on enterprises. Moreover, the pipe bending process only rolls the ends of pipe products, which is not precise and affects processing efficiency. In addition, the equipment occupies a large area, and adjusting the positioning position is troublesome for pipe products of different sizes. The high workload of employees means that the processing process cannot be effectively automated by eliminating manpower, which also affects output efficiency. Utility Model Content

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figure 1-2 This invention illustrates a high-efficiency pneumatic special machine for rolling tube products, comprising a worktable 1, a clamping mechanism, a rolling shaft 5, a fixed shaft 6, a rotating disk 7, a gear 8, a rack 9, a telescopic cylinder 10, a workpiece fixing seat 11, a material ejection mechanism 12, and a storage rack 13. The clamping mechanism, fixed shaft 6, rack 9, telescopic cylinder 10, workpiece fixing seat 11, material ejection mechanism 12, and storage rack 13 are all fixed to the worktable 1. The gear 8 is mounted on the fixed shaft 6 via bearings. The rotating disk 7 has a hole at its center that passes through the fixed shaft 6 without contacting it. The rotating disk 7... The roller is bolted to the top surface of the gear 8 and fixed thereto. The roller 5 is vertically fixed to the edge of the top surface of the rotating disk 7. The roller 5 and the fixed shaft 6 maintain a certain distance according to the size of the workpiece 14. The gear 8 is meshed with the rack 9. The rack 9 is connected to the telescopic end of the telescopic cylinder 10. When the workpiece 14 is fixed by the workpiece fixing seat 11, the end of it to be rolled is located between the roller 5 and the fixed shaft 6. After the roller is rolled, the roller 5 is reset. The unloading mechanism 12 pushes out the workpiece 14 and rotates it to the storage rack 13.

[0021] When the telescopic cylinder 10 extends, it drives the rack 9 to extend and retract. The extension and retraction of the rack 9 drives the gear 8 to rotate, thus rotating the rotating disk 7. Simultaneously, the rolling shaft 5 on the edge of its top surface rotates, pressing down on the end of the workpiece 14 to be rolled, and working together with the fixed shaft 6 to roll the end of the workpiece 14. Because the gear and rack transmission process is stable, the quality of the rolled workpiece is reliable, and the production efficiency is also improved.

[0022] As one embodiment of this utility model, the clamping mechanism includes: a cylinder mounting base 2, a clamping cylinder 3, and a polyurethane pressure plate 4. The bottom of the cylinder mounting base 2 is fixed on the workbench 1, the cylinder body of the clamping cylinder 3 is fixed to the cylinder mounting base 2 by screws, and the telescopic end of the clamping cylinder 3 is equipped with a polyurethane pressure plate 4.

[0023] The design incorporates four clamping cylinders 3, arranged in two groups of two. Each group has a polyurethane pressure plate 4 installed at its telescopic end. The two groups of clamping cylinders operate simultaneously for better workpiece clamping. The polyurethane pressure plate offers excellent wear resistance, oil resistance, high hardness, and elasticity, ensuring workpiece clamping without damage.

[0024] As an embodiment of this utility model, the unloading mechanism 12 includes a lifting cylinder 121 and a lifting block 122. The lifting block 122 has an inclined surface 1221. The workpiece 14 can rotate and roll out along the inclined surface 1221 onto the storage rack 13, which greatly reduces the operational risks for employees and alleviates the intensity of workers' work.

[0025] The workpiece fixing seat 11 includes, but is not limited to, the tube placement groove 111, the positioning seat 112 and the positioning block 113, with the positioning block 113 fixed on the tail end of the positioning seat 112.

[0026] When the workpiece 14 is too long, the positioning seat 112 cannot fully accommodate it. The following method is used: a positioning extension seat 114 is bolted to the tail end of the positioning seat 112. Similarly, the positioning stop 113 is fixed to the tail end of the positioning extension seat 114. This design can accommodate pipes of different lengths. When the workpiece 14 has inconsistent lengths, the position of the positioning stop 113 on the positioning extension seat can be adjusted to accommodate different workpiece lengths, thus achieving a multi-purpose function.

[0027] The working principle of this utility model:

[0028] After the workpiece is placed on the workpiece fixing seat 11, the telescopic rod on the clamping cylinder 3 drives the polyurethane pressure plate 4 to clamp the workpiece. The rack 9 on the telescopic cylinder 10 starts to move and drives the gear 8 to rotate. The rotation of the gear 8 drives the rolling shaft 5 on the rotating disk 7 to rotate along the central axis to roll the workpiece. After completion, the unloading mechanism 12 starts to operate, and after ejecting the workpiece, it rolls along the inclined ejector block 122.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
