Description

Technical Field

[0001] The invention relates to the technical field of copper tube processing equipment, in particular to a small-diameter threaded oxygen-free copper tube and processing equipment thereof. Background Art

[0002] Threaded oxygen-free copper tube is a pure copper tube that does not contain oxygen or any deoxidizer residue. It is a kind of non-ferrous metal tube with good electrical and thermal conductivity. It is often used in conductive accessories, transistor components and other equipment of electronic products. A variety of mechanical equipment is needed in the production of such copper tubes.

[0003] When processing and using threaded oxygen-free copper tubes, cutting equipment is used to cut the copper tubes to form copper tubes of appropriate length in order to make the length of the copper tubes meet specific usage standards. Traditional cutting equipment uses the form of cutting multiple copper tubes together to improve cutting efficiency. However, when cutting, only one pressure plate is used to limit and fix the copper tube, which makes it difficult to ensure the stability of the copper tube. As a result, the copper tube is found to be offset and shaken during the cutting process, which leads to excessive dimensional errors in the finished cut products, affecting the normal use of the copper tube and reducing the use effect and production efficiency of the cutting equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that during cutting, only one pressure plate is used to limit and fix the copper tube, which makes it difficult to ensure the stability of the copper tube, resulting in the copper tube being offset and shaking in the cutting process, which in turn leads to excessive dimensional errors in the cut products, affecting the normal use of the copper tube and reducing the use effect and production efficiency of the cutting equipment. A small-diameter threaded oxygen-free copper tube and processing equipment thereof are proposed.

[0006] The effect achieved by the above components is: when the copper tube body is cut by the cutting machine, first, the two screw holes on the surface of the mounting plate are respectively threaded with bolts, and then the mounting plate is fixedly connected to the surface of the cutting machine by means of the bolts, and then the controller is operated to start the transport component, so that the running component drives several copper tube bodies to extend forward, and then after passing through the two clamping blocks and extending to a suitable length, the servo motor on the mounting block is started to rotate the screw on the output end of the servo motor, because the limiting holes on the surface of the clamping block and the sliding limiting effect of the limiting rod make the two clamping blocks close to each other stably, until the grooves on the surfaces of the two clamping blocks contact and squeeze the arc surfaces of the copper tube bodies on both sides, and the surface of the limiting rod just contacts tangentially with the arc surface of the copper tube body, and then the cutting knife is started to cut the copper tube body, at this time, when the cutting machine cuts the copper tube body, the copper tube body can be more stable and not easy to shake, which improves the cutting effect of the copper tube body, and can cut different numbers of copper tube bodies at the same time, which improves the practicality of the fixing device and the functionality and work efficiency of the cutting machine.

[0007] Preferably, two side surfaces of the clamping block are respectively fixedly connected with reinforcement rings, the reinforcement rings are sponge rings, and the inner walls of the reinforcement rings are slidably connected to the arc surface of the screw.

[0008] The effect achieved by the above components is: through the setting of the reinforcement ring, when the clamp is moved and used, the sliding friction between the reinforcement ring and the screw can clean up the metal debris produced by cutting attached to the screw, thereby ensuring the normal movement of the clamp.

[0012] The effect achieved by the above components is: when the fixing device is used to limit and fix the copper tube body, the electric telescopic rod on the mounting frame is started, and the electric telescopic rod will drive the reinforcement plate to approach the copper tube body, so that the sliding holes on the surface of the reinforcement plate are slidably connected with the surface of the mounting frame until the reinforcement plate is in contact and squeezed with the copper tube body. At this time, the copper tube body can be more stable during cutting and is not prone to shaking, which further improves the use effect of the fixing device and the cutting effect of the cutting machine, and improves the utilization rate of the finished product of the copper tube body.

[0013] Preferably, a plurality of evenly distributed fixing grooves are provided on a side of the surface of the reinforcement plate close to the mounting plate, and the sizes of the inner walls of the plurality of fixing grooves are adapted to the copper tube body.

[0015] Preferably, inner walls of several of the fixing grooves are respectively fixedly connected with reinforcement pads, and the reinforcement pads are rubber pads.

[0016] The effect achieved by the above components is: through the provision of the reinforcement pad, the friction force when the fixing groove and the copper tube body are in contact and extruded is further improved, thereby making the position of the copper tube body more secure and improving the use effect of the reinforcement device.

[0017] Preferably, a stabilizing rod is fixedly connected to one side surface of the mounting frame, the cross section of the stabilizing rod is "L"-shaped, and the surface of the stabilizing rod is rotatably connected to the arc surface of the screw rod.

[0018] The effect achieved by the above components is that through the setting of the stabilizing rod, when the fixing device and the reinforcing plate limit and fix the copper tube body, the screw rod rotates more stably under the action of the stabilizing rod and is not prone to shaking.

[0019] Preferably, a protective device is provided on one side surface of the stabilizer bar, and the protective device includes a mounting plate, the mounting plate is fixedly connected to one side surface of the stabilizer bar, the surface of the mounting plate is fixedly connected to a rotating shaft, the surface of the rotating shaft is rotatably connected to the protective plate, and the protective plate overlaps the surface of the mounting plate.

[0020] The effect achieved by the above-mentioned components is: when cutting the copper tube body, rotate the protective plate so that the protective plate rotates on the rotating shaft fixedly connected to the surface of the assembly plate until the protective plate is in contact and squeezed with the assembly plate. At this time, the protective plate is in a horizontal state. Then, when the cutting knife cuts the copper tube body, the generated metal debris can be blocked by the protective plate, which is not easy to splash and splash into the eyes of the staff, thereby ensuring the safety of the staff, further improving the functionality of the fixing device, and further improving the working efficiency of the cutting machine.

[0022] The effects achieved by the above components are: through the setting of the handle, the protection plate is more convenient and quick to rotate, so that the protection plate is more convenient to flip over, and the convenience of using the protection device is improved.

[0023] Preferably, a positioning groove is formed on a surface of the protective plate on one side away from the handle, and a positioning block is fixed on the surface of the assembly plate, and the positioning block is snap-fitted with an inner wall of the positioning groove.

[0025] In summary, the beneficial effects of the present invention are: When the cutting machine cuts the copper tube body, the copper tube body can be more stable and less prone to shaking, which improves the cutting effect of the copper tube body. At the same time, different numbers of copper tube bodies can be cut at the same time, which improves the practicality of the fixing device and the functionality and work efficiency of the cutting machine.

[0026] When the copper tube body is cut, it can be more stable and less likely to shake, which further improves the use effect of the fixing device and the cutting effect of the cutting machine, and improves the utilization rate of the finished product of the copper tube body cutting.

[0027] When the cutting knife cuts the copper tube body, the generated metal debris can be blocked by the protective plate, which is not easy to splash and splash into the eyes of the staff, thereby ensuring the safety of the staff, further improving the functionality of the fixing device, and further improving the working efficiency of the cutting machine.
