Description

Metal tube coil pulling mechanism Technical Field

[0001] This utility model belongs to the field of metal tube winding technology, specifically a metal tube coil pulling mechanism. Background Technology

[0002] Metal tube coiling is a metal processing technique, and metal tube coiling is a type of metal tube coiling process. It involves coiling metal tubes into a ring shape according to certain specifications and requirements. Specifically, pre-produced straight metal tubes are coiled into a ring shape using coiling equipment or manual operation, according to a certain coiling method and number of turns. The quality of metal coils depends more on the material and performance of the straight metal tubes used.

[0003] As can be seen from the aforementioned patent, while metal tube coil pulling mechanisms exist, they still have drawbacks in practical use. The most obvious drawback is that after the coil rollers have been running for a long time, in order to ensure their performance and the overall stability of the equipment, regular disassembly and maintenance work is required. Currently, coil rollers are generally fixed with multiple sets of bolts, which means that workers must carry special tools such as wrenches to gradually remove the bolts. This disassembly and assembly method not only increases the burden of carrying tools for workers, but also affects the disassembly and assembly efficiency of the coil rollers, making it difficult to meet the needs of rapid maintenance and replacement, and reducing the working efficiency of the metal tube coil pulling mechanism. Therefore, we propose a metal tube coil pulling mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a metal tube coil pulling mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] Specifically, this application describes a metal tube coil pulling mechanism, comprising: an operating table and a mounting bracket slidably disposed on the top of the operating table. A first telescopic cylinder is fixedly connected to the bottom of the operating table, and a U-shaped plate is fixedly connected to the connecting end of the first telescopic cylinder. A limiting component for facilitating the positioning of the metal tube is provided on the U-shaped plate.

[0007] The mounting frame has a rotating column rotatably connected to its side wall. One end of the rotating column has a hexagonal groove, and the inner cavity of the hexagonal groove has a hexagonal block. The side wall of the hexagonal block is fixedly connected to a coil roller.

[0008] A mounting ring is fixedly connected to one end of the outer wall of the rotating column. A rotating ring is rotatably connected to the side wall of the mounting ring. A guide groove is provided on the side wall of the rotating ring. A connecting rod is slidably connected to the inner cavity of the guide groove. A moving block is rotatably connected to one end of the connecting rod. A positioning rod is fixedly connected to one end of the moving block. A through hole is provided on the side wall of the rotating column to facilitate the sliding of the positioning rod. A positioning hole matching the positioning rod is provided on the side wall of the hexagonal block. An adjusting component is provided on the mounting ring to facilitate the rotation of the rotating ring.

[0009] As a preferred technical solution of this application, the limiting member includes two sets of fixing rings, the inner cavity of the U-shaped plate is rotatably connected to a rotating rod, the two sets of fixing rings are fixedly connected to the two ends of the side wall of the rotating rod, and a clamping ring is slidably connected between the two sets of fixing rings.

[0010] As a preferred technical solution of this application, the side wall of the fixed ring is slidably connected with multiple sets of sliding rods, one end of the sliding rod is fixedly connected to the clamping ring, the other end of the sliding rod is fixedly connected to a positioning block, and a spring is fixedly connected between the positioning block and the fixed ring.

[0011] As a preferred technical solution of this application, the adjusting component includes a first connecting block and a second connecting block. The first connecting block is rotatably connected to one side wall of the mounting ring, and the second connecting block is rotatably connected to one side of the rotating ring. A screw is rotatably connected to the side wall of the first connecting block, and the second connecting block is threadedly connected to the screw.

[0012] As a preferred technical solution of this application, a motor for driving the rotating column to rotate is fixedly connected to the other side wall of the mounting bracket.

[0013] As a preferred technical solution of this application, a second telescopic cylinder is fixedly connected to the side wall of the operating table, and the power end of the second telescopic cylinder is fixedly connected to one side wall of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

[0016] 1. By creating a hexagonal groove on the rotating column, a hexagonal block and a coiled roller are supported by the hexagonal groove. A positioning rod is used to limit the hexagonal block within the hexagonal groove in conjunction with the positioning hole. When disassembling the coiled roller, the rotating ring is driven to rotate by the adjusting component. Since the rotating ring is connected to the moving block through the guide groove and the connecting rod, the rotating ring can drive the connecting rod and the moving block to move through the guide groove when it rotates. The moving block drives the positioning rod to move out of the positioning hole, so that the hexagonal block loses its limit and the coiled roller can be disassembled. This eliminates the need for workers to carry tools, improves the disassembly and assembly efficiency of the coiled roller, and increases the working efficiency of the metal tube coil pulling mechanism.

[0017] 2. By setting a rotating rod to support the fixing ring, the fixing ring supports the clamping ring through the sliding rod, and the spring applies elastic force to the positioning block and the sliding rod. The positioning block pushes the clamping ring to move, and the clamping ring clamps the metal tube, reducing the occurrence of metal tube displacement during the coiling process and making it convenient to use.

The side wall of the hexagonal block 232 is provided with a positioning hole that matches the positioning rod 262. The mounting ring 240 is provided with an adjusting component to facilitate the rotation of the rotating ring 250.

[0027] Please refer to Figures 1 and 4. The limiting component includes two sets of fixing rings 140. The inner cavity of the U-shaped plate 120 is rotatably connected to a rotating rod 130. The two sets of fixing rings 140 are fixedly connected to both ends of the side wall of the rotating rod 130. A clamping ring 160 is slidably connected between the two sets of fixing rings 140.
