Description

Technical Field

[0001] This utility model relates to the field of drawing die holders, and more specifically, to a tube drawing die holder with a cleaning function. Background Technology

[0002] In the tube manufacturing process, especially in the drawing process of metal tubes, drawing dies play a crucial role. Drawing dies are used to stretch and shape metal tubes, ensuring their final dimensions, shape, and surface quality. However, as the tubes are stretched during production, oil stains, metal shavings, rust spots, or other foreign matter may be generated. These contaminants adhere to the tube surface, affecting the tube's quality, appearance, and subsequent processing results.

[0003] A search revealed that Chinese patent CN215032384U discloses a "Metal Tube Drawing and Die-Passing Traction Device," comprising a first traction plate, a second traction plate, a traction roller, and a clamping mechanism. The clamping mechanism is fixedly disposed between the first and second traction plates. The clamping mechanism includes a crossbar disposed between the first and second traction plates, with two sliders sleeved around its outer side. Two fastening rings are connected to both sides of the two sliders. Clamping plates are welded to the bottom surfaces of both sliders. The bottom ends of the first and second traction plates are welded and fixed to connecting plates, and both connecting plates extend to a nut pair in the mounting groove. This invention adjusts the spatial distance between the two clamping plates, facilitating the clamping of metal tubes with different outer diameters and expanding the applicability of the clamping mechanism in drawing and die-passing processes. However, it still has the following drawbacks:

[0004] (1) The above application states that when using the drawing die, the oil stains adhering to the surface of the copper tube cannot be cleaned, which causes the clamp to slip frequently and affects production efficiency.

[0005] (2) When using the drawing die base mentioned above, the water stains remaining on the surface of the copper tube cannot be wiped off, which causes the clamps to slip due to the water stains on the surface of the copper tube. Therefore, a tube drawing die base with a cleaning function is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that the current method cannot clean oil stains on the surface of copper tubes, which causes frequent slippage of the clamps and affects production efficiency.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a pipe drawing die base with a cleaning function, including a base plate, a support leg fixedly connected to the bottom of the base plate, a drawing die base provided on the top of the base plate, and a cleaning device provided on the top of the base plate;

[0009] The cleaning device includes a motor, the bottom of which is fixedly connected to the top of a base plate. A threaded rotating rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rotating rod. A push rod is fixedly connected to the circumferential surface of the threaded sleeve. A water tank is fixedly connected to the top of the base plate. A water outlet is provided on the side of the water tank. A water supply pipe is fixedly connected to the inner wall of the water outlet. A cleaning ring is fixedly connected to the end of the water supply pipe away from the water outlet. A connecting shaft slides through the side of the water tank. A piston plate is fixedly connected to the side of the connecting shaft. The front side of the piston plate is slidably connected to the inner wall of the water tank.

[0010] As a preferred technical solution of this utility model, a return spring is fixedly connected to the circumferential surface of the connecting shaft. The end of the return spring away from the connecting shaft is fixedly connected to the side of the water tank. A limit rod is fixedly connected to the side of the motor. The circumferential surface of the limit rod slides through the inner wall of the threaded sleeve. The function of the return spring is to allow the connecting shaft to be reset when the push bar stops pushing the connecting shaft.

[0011] As a preferred technical solution of this utility model, the inner wall of the drawing die base is provided with a drainage groove, and a collection box is fixedly connected to the front and side of the drawing die base. The function of the collection box is to collect the wastewater left over from the washing process.

[0012] As a preferred technical solution of this utility model, the side of the connecting shaft is located on the displacement trajectory of the push bar, the side of the piston plate is located to the right of the water outlet, and the top of the collection box is located below the diversion groove. The purpose of the side of the connecting shaft being located on the displacement trajectory of the push bar is to push the connecting shaft to move when the push bar moves.

[0013] As a preferred technical solution of this utility model, a wiping device is provided on the top of the base plate. The wiping device includes a first sprocket, the side of which is fixedly connected to the side of the threaded rotating rod. A chain is provided on the circumferential surface of the first sprocket, and a second sprocket is provided on the inner wall of the chain. A support shaft is fixedly connected to the side of the second sprocket, and the side of the support shaft is rotatably connected to the inner wall of the drawing die base.

The function of the circumferential surface of the first sprocket meshing with the inner wall of the chain is to drive the chain to rotate when the first sprocket rotates, and the function of the circumferential surface of the drive gear meshing with the circumferential surface of the gear ring is to drive the gear ring to rotate when the drive gear rotates.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The cleaning device allows the push bar to move to the left, which in turn pushes the connecting shaft into the water tank. When the connecting shaft moves, it drives the piston plate to move. As the piston plate moves, it squeezes the cleaning agent in the water tank out of the outlet and into the cleaning ring through the water pipe. This allows the cleaning agent to flow out of the cleaning ring to clean the drawn copper tube, preventing the surface of the copper tube from being contaminated with oil after the drawing die pulls it out, which would cause the clamp to slip frequently and affect production efficiency.

[0018] 2. The wiping device allows the chain to rotate when the first sprocket rotates, which in turn drives the second sprocket to rotate, which in turn drives the support shaft to rotate, which in turn drives the drive gear to rotate, which in turn drives the gear ring to rotate, which in turn drives the sponge to rotate, allowing the sponge to better absorb the water stains remaining on the surface of the copper pipe.
