Description

Technical Field

[0001] This utility model relates to the field of cold-drawn tube production technology, and in particular to a bundling and fixing device for cold-drawn tube production. Background Technology

[0002] Cold-drawn tubes are high-precision steel tubes produced through cold drawing or cold rolling. These tubes possess advantages such as no oxide layer on the inner and outer walls, high pressure resistance without leakage, high precision, high surface finish, no deformation after cold bending, and no cracks after flaring or flattening. Therefore, they are widely used in the production of pneumatic or hydraulic components, such as cylinders or oil cylinders. However, during the production process, cold-drawn tubes require bundling and securing for convenient transportation in large quantities. Existing bundling and securing methods for cold-drawn tubes still present some problems:

[0003] 1. In the existing process of bundling and fixing cold-drawn tubes, the binding force is not strong enough, resulting in the internal structure of the bundled cold-drawn tubes being extremely loose. Such bundled cold-drawn tubes also have a high risk of falling during transportation.

[0004] 2. Currently, most cold-drawn tubes are still fixed manually during the bundling process. This method is not only inefficient, but also results in a large number of cold-drawn tubes being piled up together, making it inconvenient to manually bundle them. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bundling and fixing device for cold-drawn tube production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bundling and fixing device for cold-drawn tube production includes an operating table. The top outer wall of the operating table has symmetrically distributed rectangular slots, and a guide rail is provided below the rectangular slots. Symmetrically distributed guide blocks are slidably inserted into the inner wall of the guide rail, and an arc-shaped clamp is welded to the top outer wall of the guide blocks. A first electric telescopic rod is bolted to the middle outer wall of the operating table, and a rectangular top plate is fixed to the piston rod of the first electric telescopic rod. An electric slip ring is installed in the middle of the rectangular top plate, and a rotating shaft is connected to the inner wall of the electric slip ring. A connecting plate is welded to the bottom outer wall of the rotating shaft, and sliding grooves are opened at both ends of the top of the connecting plate. A sliding connecting rod is slidably inserted into the inner wall of the sliding groove, and a wire-passing groove is opened through the bottom of the sliding connecting rod. A rectangular groove is opened along the width direction in the middle of the operating table.

[0008] As a further embodiment of this utility model: the two sliding links are connected to a second electric telescopic rod on the outer wall of the opposite side, and the second electric telescopic rod is connected to an electric slip ring through a wire.

[0009] As a further embodiment of this utility model: a first helical gear is welded to the top outer wall of the rotating shaft, and a second helical gear is meshed above the first helical gear in a vertical direction, and a drive motor is connected to the axis of the second helical gear.

[0010] As a further improvement of this utility model: the inner wall of the arc-shaped clamp is bonded with an anti-slip rubber pad, and the outer wall of the protective rubber pad is provided with anti-slip threads.

[0011] As a further embodiment of this utility model: a cutting blade holder is fixed on one outer wall of the operating table, and a servo cylinder is fixed on the other outer wall of the operating table. A cutting blade is fixed at the piston rod of the servo cylinder, and the cutting blade is adapted to the cutting blade holder.

[0012] As a further improvement of this utility model: the inner walls on both sides of the sliding groove are provided with balance slots along the length direction, and the outer walls on both sides of the sliding connecting rod are welded with balance blocks, and the balance slots and balance blocks form a sliding fit.

[0013] As a further improvement of this utility model: a bidirectional lead screw is screwed to the inner wall of the middle part of the guide block, and a servo motor is connected to one side of the bidirectional lead screw through a coupling.

[0014] Compared with the prior art, this utility model provides a bundling and fixing device for cold-drawn tube production, which has the following advantages:

[0015] 1. The cold-drawn tube bundling and fixing device designed in this paper improves the overall stability of the bundled cold-drawn tubes when bundling and fixing a large number of them. It uses a servo motor to drive two arc-shaped clamps to move closer to each other, thereby gathering and clamping the cold-drawn tubes to be bundled and fixing them. This assists in the bundling process and effectively improves work efficiency.

[0016] 2. The cold-drawn tube bundling and fixing device designed in this paper uses an electric telescopic rod to pass the wire to be bundled through the bottom of the cold-drawn tube and gather and squeeze it. After completion, the drive motor drives the wire to rotate, thereby tightening it and completing the bundling and fixing operation.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] A bundling and fixing device for cold-drawn tube production, in this embodiment, as follows: Figure 1-4 As shown, the system includes an operating table 1. The top outer wall of the operating table 1 has symmetrically distributed rectangular through slots 2, and a guide rail 3 is provided below the rectangular through slots 2. The inner wall of the guide rail 3 is slidably connected to symmetrically distributed guide blocks 4, and the top outer wall of the guide blocks 4 is welded with an arc-shaped clamping plate 5. The middle outer wall of the operating table 1 is fixed with bolts to a first electric telescopic rod 8, and a rectangular top plate 9 is fixed to the piston rod of the first electric telescopic rod 8. An electric slip ring 10 is installed in the middle of the rectangular top plate 9, and a rotating shaft 11 is connected to the inner wall of the electric slip ring 10. A connecting plate 15 is welded to the bottom outer wall of the rotating shaft 11, and sliding grooves 16 are opened at both ends of the top of the connecting plate 15. A sliding connecting rod 17 is slidably connected to the inner wall of the sliding groove 16, and a wire-passing groove 18 is opened through the bottom of the sliding connecting rod 17. A rectangular groove 23 is opened in the middle of the operating table 1 along the width direction.

[0026] When bundling and fixing a large number of cold-drawn tubes, in order to improve the overall firmness after bundling, a servo motor 7 is used to drive two arc-shaped clamps 5 to move closer to each other, thereby gathering and clamping the cold-drawn tubes that need to be bundled, thus assisting in the bundling process and effectively improving work efficiency.

[0027] Two sliding connecting rods 17 are connected to a second electric telescopic rod 19 on the outer wall of the opposite side, and the second electric telescopic rod 19 is connected to an electric slip ring 10 through a wire. A first helical gear 12 is welded to the top outer wall of the rotating shaft 11, and a second helical gear 13 is meshed on the top of the first helical gear 12 in the vertical direction. A drive motor 14 is connected to the axis of the second helical gear 13.

[0028] The inner wall of the arc-shaped clamp 5 is bonded with an anti-slip rubber pad, and the outer wall of the protective rubber pad is provided with anti-slip threads.

[0029] A cutting blade holder 20 is fixed on one side of the outer wall of the operating table 1, and a servo cylinder 21 is fixed on the other side of the outer wall of the operating table 1. A cutting blade 22 is fixed at the piston rod of the servo cylinder 21, and the cutting blade 22 is adapted to the cutting blade holder 20.

[0030] When bundling cold-drawn tubes, the electric telescopic rods are used to pass the wires to be bundled through the bottom of the cold-drawn tubes and gather and squeeze them together. After that, the drive motor 14 is used to drive the wires to rotate, thereby tightening them and completing the bundling and fixing operation.

[0031] In this embodiment, the bundling and fixing device is first assembled and then connected to an external power supply for trial operation. After the operation is completed, the cold-drawn tubes to be bundled are placed at the top center of the operating table 1. Then, the servo motor 7 is started, and the servo motor 7 drives the two arc-shaped clamps 5 to move closer to each other, thereby gathering, clamping and limiting the cold-drawn tubes. After clamping and fixing, the wire to be fixed is passed through the inside of the wire groove 18. When the length is appropriate, the servo cylinder 21 drives the cutting blade 22 to cut the wire. Then, the second electric telescopic rod 19 pushes the sliding connecting rod 17 to move closer together. During the process of moving closer together, the first electric telescopic rod 8 is slowly raised, so that the wires gather around the cold-drawn tubes and form a near-closed trend. When the two ends of the wires are close to the middle of the cold-drawn tube, the drive motor 14 drives the sliding connecting rod 17 to rotate, and the ends of the wires are tightened, thereby completing the bundling of the cold-drawn tubes. After bundling and fixing for one turn, the cold-drawn tubes are pushed forward to complete the bundling and fixing of the next section.

The balance slots and balance blocks form a sliding fit. The inner wall of the middle part of the guide block 4 is screwed with a bidirectional lead screw 6, and one side of the bidirectional lead screw 6 is connected to a servo motor 7 through a coupling.
