Description

Technical Field

[0001] This utility model relates to the field of threading machine technology, specifically a threading machine with an auxiliary feeding mechanism. Background Technology

[0002] A threading machine is a tool used to process external threads on pipes. It can easily and quickly complete the threading of pipes during installation. A threading machine typically consists of a machine body, a motor, a gearbox, a pipe chuck, a die head, a cutter holder, a feed device, and a cooling system. These components work together to enable the threading machine to efficiently complete the threading task.

[0003] During operation, the pipe to be threaded is placed into the chuck and clamped. The chuck rotates as the switch is activated. After adjusting the die cutter position and setting the thread length, the feed handwheel is turned, and the die cutter automatically begins cutting. Simultaneously, the cooling system sprays oil to cool the die cutter. This automated operation significantly reduces the labor intensity of workers and improves work efficiency.

[0004] However, common threading machines require a feed device to move the pipe and die head relative to each other when machining external threads on pipes. The feed device increases the cost of the threading machine, while manual feed is not stable enough. Therefore, this application proposes a threading machine with an auxiliary feeding mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a threading machine with an auxiliary feeding mechanism, which has advantages such as automatic feed through the thread. This solves the problem that common threading machines require a feed device to move the pipe and die head relative to each other when machining external threads on pipes. The feed device increases the cost of the threading machine, while manual feed has the problem of instability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a threading machine with an auxiliary feeding mechanism, comprising a mounting box, a fixed plate fixedly mounted on the top of the mounting box, a clamp rotatably mounted on one side of the fixed plate, a movable plate slidably mounted on the top of the mounting box, a sliding connecting cylinder passing through one side of the movable plate, an mounting groove fixedly mounted on one end of the sliding connecting cylinder near the clamp, and a die embedded inside the mounting groove;

[0007] The movable plate has an installation through hole on one side that is compatible with the sliding connecting cylinder. Four locking strips are fixedly installed on the surface of the sliding connecting cylinder. The wall of the installation through hole has a limiting groove that is compatible with the locking strip.

[0008] Furthermore, the surface of the mounting groove is provided with four threaded holes, and locking screws are installed inside the threads of the threaded holes, with one end of the locking screws contacting the surface of the die.

[0009] Furthermore, a limiting sleeve is fixedly installed on the side of the movable plate away from the mounting groove, and a spring is fixedly installed on the inner wall of the limiting sleeve, with one end of the spring fixedly connected to one end of the sliding connecting cylinder.

[0010] Furthermore, a rotating motor is fixedly installed on the side of the fixing plate away from the clamp, and the output end of the rotating motor is fixedly connected to one side of the clamp.

[0011] Furthermore, an adjusting screw is rotatably mounted on the inner side wall of the mounting box, and a slider threadedly connected to the adjusting screw is slidably mounted inside the mounting box.

[0012] Furthermore, the top of the mounting box is provided with a connecting hole, and a connecting block is slidably installed inside the connecting hole. The bottom of the connecting block is fixedly connected to the top of the slider, and the top of the connecting block is fixedly connected to the bottom of the movable plate.

[0013] Furthermore, a turntable is rotatably mounted on one side of the mounting box, and the rotation shaft of the turntable is fixedly connected to one end of the adjusting screw.

[0014] Compared with the prior art, this utility model provides a threading machine with an auxiliary feeding mechanism, which has the following advantages:

[0015] This threading machine with an auxiliary feeding mechanism works by fixing an mounting groove to one end of a sliding connecting cylinder, embedding the die in the mounting groove, and moving the sliding connecting cylinder via a movable plate, causing the die to contact the pipe mounted on the clamp. When the movable plate stops moving, the clamp rotates, causing the pipe to rotate. Under the action of the thread, there is a forward force on the die. The sliding connecting cylinder slides on one side of the movable plate, causing the die to advance automatically and thread the pipe surface. This solves the problem of common threading machines requiring a feed device to move the pipe and die head relative to each other when processing external pipe threads. The feed device increases the cost of the threading machine, while manual feed has the problem of instability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 A threading machine with an auxiliary feeding mechanism includes a mounting box 1. A fixed plate 2 is fixedly installed on the top of the mounting box 1. A clamp 3 is rotatably installed on one side of the fixed plate 2. A movable plate 4 is slidably installed on the top of the mounting box 1. A sliding connecting cylinder 5 is passed through one side of the movable plate 4. An installation groove 6 is fixedly installed at one end of the sliding connecting cylinder 5 near the clamp 3. A die 7 is embedded inside the installation groove 6.

[0022] The movable plate 4 has a mounting through hole 41 on one side that matches the sliding connecting cylinder 5. Four retaining strips 51 are fixedly installed on the surface of the sliding connecting cylinder 5. The wall of the mounting through hole 41 has a limiting groove 42 that matches the retaining strips 51. The retaining strips 51 are engaged in the limiting groove 42, so that the sliding connecting cylinder 5 slides inside the mounting through hole 41 and cannot rotate.

[0023] Install the pipe onto one side of the clamp 3. Move the movable plate 4 toward one end of the pipe so that the die 7 contacts the pipe. Rotate the clamp 3 and the die 7 will create threads on the surface of the pipe. As the pipe continues to rotate, the die 7 will have a forward force under the action of the threads. The sliding connecting cylinder 5 will slide, causing the die 7 to move forward automatically and complete the threading.

[0024] Meanwhile, the surface of the mounting groove 6 has four threaded holes 61, and locking screws 62 are installed inside the threads of the threaded holes 61. One end of the locking screw 62 contacts the surface of the die 7. The die 7 is inserted into the mounting groove 6 and fixed by the locking screw 62 to prevent the die 7 from rotating with the pipe. When processing pipes of different sizes, dies 7 of different specifications can be replaced.

[0025] A limiting sleeve 8 is fixedly installed on the side of the movable plate 4 away from the mounting groove 6. A spring 9 is fixedly installed on the inner wall of the limiting sleeve 8, and one end of the spring 9 is fixedly connected to one end of the sliding connecting cylinder 5. The limiting sleeve 8 and the sliding connecting cylinder 5 are connected by the spring 9 to prevent the sliding connecting cylinder 5 from advancing too far and separating from the movable plate 4.

[0026] Secondly, a rotary motor 10 is fixedly installed on the side of the fixing plate 2 away from the clamp 3, and the output end of the rotary motor 10 is fixedly connected to one side of the clamp 3. The rotary motor 10 rotates forward and backward, driving the clamp 3 to rotate forward and backward, and thus driving the pipeline to rotate forward and backward.

[0027] Meanwhile, an adjusting screw 11 is rotatably mounted on the inner wall of the mounting box 1, and a slider 12, threadedly connected to the adjusting screw 11, is slidably mounted inside the mounting box 1. Rotation of the adjusting screw 11 causes the slider 12 to slide inside the mounting box 1.

[0028] The mounting box 1 has a connecting hole 13 on its top. A connecting block 14 is slidably installed inside the connecting hole 13. The bottom of the connecting block 14 is fixedly connected to the top of the slider 12, and the top of the connecting block 14 is fixedly connected to the bottom of the movable plate 4. When the slider 12 moves, it moves the connecting block 14, which in turn moves the movable plate 4.

[0029] Finally, a turntable 15 is rotatably mounted on one side of the mounting box 1, and the rotation shaft of the turntable 15 is fixedly connected to one end of the adjusting screw 11. Rotating the turntable 15 drives the movable plate 4 to move.

[0030] In this embodiment, when in use, the pipe is installed on one side of the clamp 3, the motor 10 is rotated clockwise to drive the pipe to rotate, the turntable 15 is rotated so that the die 7 is close to the pipe, the turntable 15 is rotated to open the thread on the surface of the pipe until the die 7 moves forward automatically, the turntable 15 can be stopped to rotate, when the thread is opened, the motor 10 is rotated in reverse to retract the die 7, the turntable 15 is rotated in reverse to retract the die 7.

[0031] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
