Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing other special products, in particular to a traction device for a pipe threading machine. Background Art

[0002] PTC (Positive Temperature Coefficient) fin tubes (hereinafter referred to as PTC strips) need to be penetrated with insulating paper, which is generally operated by a tube threading machine. After the insulating paper is cut into a specified length, the traction device on the tube threading machine drives the steel strips and insulating paper to be pulled out of the PTC fin tube, thereby completing the traction work. The Chinese utility model patent, authorization announcement number "CN218080101U" discloses a tube threading machine traction device. The utility model is provided with a stabilizing component to facilitate the steel strip to be pushed and moved in the guide block. When passing through the limit plate, the steel strip squeezes the limit plate and slides in the placement groove. Through the reaction force of the spring, the limit plate can be pressed against the four sides of the steel strip, which can stabilize the steel strip when it moves.

[0003] During use of the above technical solution, since the four springs press against the four sides of the steel bar through the corresponding limit plates, the four limit plates will approach each other under the support of the corresponding springs, which will hinder the steel bar from passing through the guide block. Therefore, the operator is required to use tools to open the four limit plates to allow the steel bar to pass through the inside of the guide block, which greatly reduces the efficiency of the steel bar passing through the guide block. Therefore, we propose a pipe threading machine traction device. Utility Model Content

[0025] The guide assembly includes a guide plate 5, which is fixedly connected to the top of the pipe threading traction platform 1.

The multiple clamping plates 17 are all L-shaped, and guide rollers 18 are rotatably connected inside the two corresponding clamping plates 17.

[0028] Furthermore, when using the device, the drive motor 11 is started by connecting an external power supply, and the drive motor 11 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 causes the pressing plate 8 to move downward under the guidance of the limit rod 7, thereby facilitating the fixation of the PTC fin tube placed on the mounting groove 9 of the positioning plate 12. The external power supply is connected to start the two electric push rods 6, and the two electric push rods 6 drive the corresponding moving plates 13 away from the guide cylinder 15.

[0029] Through the cooperation of two electric push rods 6, two movable plates 13, multiple connecting plates 16 and multiple clamping plates 17, when the steel bar needs to pass through the inside of the guide tube 15, the two clamping plates 17 can slide in the adjustment groove 4 and move away from each other, so that the steel bar can directly pass through the guide tube 15.

[0030] By means of the guide rollers 18 arranged on the clamping plates 17, after the two clamping plates 17 contact and clamp the steel bar, the guide rollers 18 can ensure that the steel bar can slide smoothly in the guide tube 15 when pushed by the pushing plate 3, thereby avoiding large friction between the two clamping plates 17 and the surface of the steel bar, thereby reducing the friction between the two clamping plates 17 and the steel bar.

[0031] Working principle: by connecting an external power supply to start the driving motor 11, the driving motor 11 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 causes the pressing plate 8 to move downward under the guidance of the limit rod 7, so as to facilitate the fixation of the PTC fin tube placed on the mounting groove 9 of the positioning plate 12, and connecting the external power supply to start the two electric push rods 6, the two electric push rods 6 drive the corresponding moving plates 13 away from the guide cylinder 15, and the two moving plates 13 move in the opposite direction to drive the corresponding multiple connecting plates 16 to move, and the movement of the multiple connecting plates 16 will drive the corresponding clamping plates 17 to slide in the corresponding adjustment grooves 4, so as to facilitate the steel bars to be fixed one by one. It should pass through multiple guide cylinders 15, and then the two electric push rods 6 drive the corresponding moving plates 13 to bring the multiple clamping plates 17 thereon into contact with the surface of the steel bar. The electric telescopic rod 2 is started by connecting an external power supply. The electric telescopic rod 2 extends to drive the push plate 3 to slide on the top of the tube-threading traction platform 1, so that the push plate 3 pushes the steel bar to pass through the corresponding PTC fin tube.
