Technical Field
[0001] The utility model relates to the technical field of cold-drawn tubes, in particular to an automatic flushing machine for cold-drawn tubes. Background Art
[0002] Cold-drawn tube is a seamless steel tube produced by cold working method, and its production process involves plastic deformation of metal. The precision and surface quality of cold-drawn tube are significantly better than hot-rolled tube, but due to process constraints, its caliber and length are subject to certain restrictions. Cold-drawn tube is widely used in mechanical structures, hydraulic equipment and other fields due to its high precision and good surface finish. The use of precision seamless tubes to manufacture mechanical structures or hydraulic equipment can greatly save machining time, improve material utilization, and help improve product quality. In the production process of cold-drawn tubes, plastic processing is required, so after processing, the cold-drawn tubes need to be cleaned, but there are still some problems with the existing flushing machines when cleaning:
[0003] 1. Poor cleaning effect. The existing cold-drawn tube cleaning process cannot effectively clean the stubborn stains on the outer wall of the cold-drawn tube. In addition, due to its circular outer wall, there are easy to be dead corners during cleaning, which cannot effectively clean the outer wall of the round tube, resulting in poor overall cleaning effect.
[0004] 2. Poor adaptability. When cleaning cold-drawn tubes, the existing cold-drawn tube flushing device cannot adjust the size of the internal cleaning mechanism. As a result, the cleaning machine can only clean the outer wall of cold-drawn tubes of certain sizes, but cannot clean cold-drawn tubes of various sizes, greatly reducing the overall practicality of the cleaning machine.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] Example 1:
[0027] An automatic flushing machine for cold drawn tubes, this embodiment, as Figure 1-4 As shown, it includes a fixed frame 1, a top outer wall of the fixed frame 1 is penetrated by a guide groove 2, and the inner wall of the guide groove 2 is slidably inserted with a guide slider 3, the top side of the guide slider 3 is fixed with an electric telescopic rod 4 by screws, and the bottom outer wall of the guide slider 3 is fixed with a first annular plate 5 by screws, one side of the first annular plate 5 is fixed with an annular slide 6, and the inner wall of the annular slide 6 is slidably connected with an arc-shaped slider 7, the outer wall of the arc-shaped slider 7 is welded with a second annular plate 10, and the outer wall of the second annular plate 10 is provided with sliding grooves 11 distributed at equal distances, the inner wall of the sliding groove 11 is slidably inserted with a sliding block 12, one side of the sliding block 12 is connected to a servo cylinder 13, and the outer wall of the sliding blocks 12 close to each other is welded with an arc-shaped cleaning brush plate 14, the side wall of the second annular plate 10 is welded with an outer gear ring 15, and the outer gear ring 15 is engaged with a gear 16, and the axis of the gear 16 is connected with a servo motor 17;
[0028] By placing the cold-drawn tube on the U-shaped bracket 20 and cooperating with the continuously rotating rubber wheel 23, the cold-drawn tube can be pushed to move at a uniform speed, so that the outer wall of the cold-drawn tube can be effectively cleaned by cooperating with the continuously rotating arc-shaped cleaning brush plate 14, and the cold-drawn tube is passed through the flushing nozzle 19 to wet and clean the stains on the outer wall of the cold-drawn tube, thereby greatly improving the subsequent cleaning effect.
[0029] A compression spring 8 is welded to the outer wall of one side of the arc-shaped slider 7, and a limit stopper 9 is welded to the outer wall of the side of the compression spring 8 away from the arc-shaped slider 7. The limit stopper 9 is welded to the inner wall of the bottom of the annular chute 6. An annular water pipe 18 is provided on both sides of the first annular plate 5, and the inner wall of the annular water pipe 18 is screwed with flushing nozzles 19 distributed at equal distances. The axis of the annular water pipe 18 is located on the same straight line as the axis of the annular water pipe 18;
[0030] U-shaped brackets 20 are provided on both sides of the bottom of the fixed frame 1 , and telescopic adjustment rods 21 are welded to the outer walls of the bottom of the U-shaped brackets 20 .
[0031] The telescopic adjustment rod 21 includes a load-bearing tube and a load-bearing rod slidably inserted into the inner wall of the load-bearing tube, and a fastening bolt is connected to the outer wall of one side of the load-bearing tube through a thread, and the fastening bolt forms a tight fit with the load-bearing rod;
[0032] During the cleaning process of the cold-drawn tube, the servo cylinder 13 is used to drive the sliding block 12 to adjust its position, so that the spacing between the arc-shaped cleaning brush plates 14 can be quickly adjusted to adapt to cold-drawn tubes of different diameters for fitting cleaning, greatly improving the overall practicality of the cleaning machine and effectively removing stubborn stains.
[0033] When using this embodiment, the cleaning machine is first assembled and connected to an external power supply. The cold-drawn tube to be cleaned is then placed on the U-shaped bracket 20, and the annular water pipe 18 is connected to the external water pipe. The outer wall of the cold-drawn tube is first wetted by the flushing nozzle 19, and a preliminary cleaning is performed. Then, the driving motor 24 is started to drive the rubber wheel 23 to rotate, thereby pushing the cold-drawn tube to move. When the cold-drawn tube moves to the inner wall of the second annular plate 10, the servo cylinder 13 is first used to drive the sliding block 12 to slide, and the arc-shaped cleaning brush plate 14 is pressed against the cold-drawn tube. The outer wall of the drawn tube is quickly adapted to cold-drawn tubes of different diameters, and then the servo motor 17 is started. The servo motor 17 drives the missing gear 16 to rotate, and the missing gear 16 drives the outer gear ring 15 to rotate, thereby driving the arc-shaped cleaning brush plate 14 to rotate continuously. When the missing tooth part of the missing gear 16 loses its bite force, the internal compression spring 8 quickly pushes the second annular plate 10 to reset, thereby driving the arc-shaped cleaning brush plate 14 to rotate quickly to complete the cleaning, and during the cleaning process, the electric telescopic rod 4 at the top drives the arc-shaped cleaning brush plate 14 to move back and forth continuously, thereby further cleaning the outer wall of the cold-drawn tube.
[0034] Example 2:
[0035] An automatic flushing machine for cold drawn tubes, such as Figure 1-4 As shown, this embodiment is supplemented by the following on the basis of Example 1: a rectangular through-slot 22 is formed on the inner wall of one side of the U-shaped bracket 20, and a rubber wheel 23 is provided inside the rectangular through-slot 22. A drive motor 24 is connected to the bottom axis of the rubber wheel 23. The electric telescopic rod 4, the servo cylinder 13, the servo motor 17 and the drive motor 24 are all connected to a PLC controller via signal lines, and the PLC controller is connected to an external power supply via a wire. The effective tooth length of the missing gear 16 accounts for three-quarters of the circumference length of the missing gear 16.
[0036] When this embodiment is used, while the outer wall of the cold-drawn tube is being cleaned by reciprocating rotation, the electric telescopic rod 4 at the top is also used to drive the arc-shaped cleaning brush plate 14 at the bottom to move back and forth left and right. The positions of the arc-shaped cleaning brush plates 14 are adjusted in two different directions for coordinated cleaning, thereby quickly cleaning the outer wall of the cold-drawn tube.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
