Description

Technical Field

[0001] This utility model belongs to the field of copper tube cutting technology, specifically, it relates to a copper tube intermittent feeding and cutting device. Background Technology

[0002] In modern manufacturing, copper pipes, as an important industrial raw material, are widely used in air conditioning and refrigeration, power transmission, chemical equipment, and building water supply and drainage. With the rapid development of industrial technology and the continuous improvement of product quality requirements, higher demands are placed on the precision and efficiency of copper pipe cutting. Traditional copper pipe cutting methods mainly include manual sawing, mechanical sawing, and ordinary cutting machine cutting. While manual sawing is inexpensive, it is labor-intensive, has poor cutting precision, and low efficiency, making it difficult to meet the needs of mass production. Mechanical sawing improves cutting efficiency to some extent, but still has significant shortcomings in feed control, positioning accuracy, and cutting quality. Existing ordinary cutting machines, although capable of automated cutting, have obvious defects in intermittent feed control, making it difficult to accurately control the feed amount, easily leading to material waste and inaccurate cutting dimensions. Current positioning mechanisms often use simple clamping structures with limited positioning accuracy, making workpiece slippage during cutting easy and affecting cutting quality. The cooling method for cutting tools often relies on external spray cooling, which is ineffective, resulting in severe tool wear and low cutting efficiency. The existing equipment suffers from an unreasonable transmission system design, low power transmission efficiency, and poor operational stability. These technical problems severely restrict the development of copper tube cutting and processing, necessitating an urgent need for a copper tube cutting device capable of precise intermittent feeding, accurate positioning, and efficient cutting.

The movable jaw is connected to the piston rod of the clamping cylinder through a guide rod. The clamping cylinder is fixed to the side of the support base.

[0005] The technical effects of the intermittent feeding and cutting device for copper tubes provided by this utility model are as follows: Through the coordinated cooperation of the feeding mechanism, cutting mechanism, positioning mechanism, transmission mechanism and support base, the automated intermittent feeding and precise cutting of copper tubes are realized. The L-shaped feeding guide rail and the propulsion cylinder form a stable feeding channel. The disc-shaped cutting blade is driven by the drive motor to achieve efficient cutting. The positioning fixture ensures the precise positioning of the copper tube cutting position through the cooperation of fixed jaws and movable jaws. The overall structure is compact and reasonable, and the functions of each component are clear, which effectively improves the automation level and processing accuracy of copper tube cutting.

[0006] Based on the above technical solution, the intermittent feeding and cutting device for copper tubes of this utility model can be further improved as follows: The feed guide rail has multiple equidistantly distributed positioning grooves on its guide surface. The positioning grooves are V-shaped grooves with a depth of 3mm to 8mm, a width of 1.2 to 1.5 times the outer diameter of the copper tube, a spacing of 2 to 3 times the outer diameter of the copper tube, and a circular arc bottom.

[0007] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by opening multiple equidistantly distributed V-shaped positioning grooves on the guide surface of the feeding guide rail, the copper tube can be accurately positioned and slide stably during the feeding process. The V-shaped groove structure matches the circular cross-sectional shape of the copper tube, providing good positioning and guiding function. The reasonable design of the depth, width and spacing of the positioning grooves ensures the adaptability of copper tubes of different specifications. The arc-shaped structure at the bottom of the groove reduces the contact stress between the copper tube and the guide rail, effectively preventing deformation and damage of the copper tube during the feeding process.

The cutting edge of the cutting blade is provided with multiple radially distributed cooling grooves, and the depth of the cooling grooves is 0.5mm to 1.5mm.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a coolant channel inside the cutting tool holder drive shaft, continuous cooling of the cutting blade is achieved, which effectively reduces the temperature during the cutting process and reduces the problems of tool wear and copper tube cut surface quality degradation caused by high temperature. The hollow shaft structure of the coolant channel is ingeniously designed, with coolant entering from the top of the drive shaft, flowing out from the bottom, and achieving uniform cooling through the cutting blade center hole and radial cooling groove, which significantly improves cutting efficiency and cutting quality.

[0010] Furthermore, the fixed jaw of the positioning clamp has a semi-circular structure, and the inner surface of the fixed jaw is provided with anti-slip texture. The movable jaw has a semi-circular structure and is arranged opposite to the fixed jaw. The inner surface of the movable jaw is provided with anti-slip texture that matches the fixed jaw. When the fixed jaw and the movable jaw are closed, they form a complete circular clamping surface. The inner diameter of the circular clamping surface is 0.1 mm to 0.3 mm smaller than the outer diameter of the copper tube.

[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the semi-circular fixed jaw and movable jaw of the positioning fixture are designed to accurately clamp and position the copper tube. The anti-slip texture enhances the clamping force and prevents the copper tube from slipping during the cutting process. The complete circular clamping surface formed after the fixed jaw and movable jaw close together is precisely matched with the outer diameter of the copper tube, ensuring the stability and reliability of the clamping. The design of the inner diameter being 0.1mm to 0.3mm smaller than the outer diameter of the copper tube ensures a moderate clamping force, which can stably clamp the copper tube without causing excessive pressure and deformation.

[0012] Furthermore, the front surface of the pusher plate has a concave arc-shaped structure, the radius of curvature of the concave arc-shaped structure matches the outer diameter of the copper tube, and the two sides of the pusher plate are provided with guide protrusions, which cooperate with the guide surface of the feeding guide rail. The material of the pusher plate is stainless steel.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the concave arc structure design on the front surface of the pusher plate increases the contact area between the pusher plate and the copper tube, making the pushing force distribution more uniform and effectively reducing the local stress concentration of the copper tube during the pushing process. The guide protrusions on both sides of the pusher plate and the cooperation with the feeding guide rail ensure the straightness and stability of the pushing process. The use of stainless steel material improves the corrosion resistance and service life of the pusher plate.

The transmission ratio between the main gear and the first driven gear is 1:2, and the transmission ratio between the first driven gear and the second driven gear is 1:3.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: Through the design of the main drive shaft and driven gear set of the transmission mechanism, the power transmission of the drive motor and the speed distribution are realized effectively. The transmission ratio of 1:2 between the main gear and the first driven gear and the transmission ratio of 1:3 between the first driven gear and the second driven gear form a total transmission ratio of 1:6 reduction transmission, which effectively reduces the speed of the cutting blade, increases the cutting torque, and ensures the stability and cutting quality of the cutting process. The multi-stage gear transmission design makes the power transmission smoother and reduces vibration and noise.

[0016] Furthermore, the surface of the support base is provided with a plurality of circular protrusions, the diameter of which is 10mm to 20mm and the height of which is 2mm to 5mm. The circular protrusions are distributed in a rectangular array on the surface of the support base.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting multiple circular protrusions on the surface of the support base, the friction between the base and the mounting surface is increased, which effectively prevents the device from slipping and displacing during operation. The rectangular array distribution design of the circular protrusions ensures the uniform distribution of the contact area and improves the stability of the device. The reasonable design of the height and diameter of the protrusions provides sufficient support while avoiding excessive stress concentration. The circular protrusions also play a role in vibration reduction, reducing the transmission of vibration during operation.

[0018] Furthermore, the guide surface of the feed guide has a wave-shaped structure, the peak height of the wave-shaped structure is 1mm to 3mm, the wavelength of the wave-shaped structure is 5mm to 10mm, and the wave-shaped structure is continuously distributed along the length direction of the guide surface.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the wave-shaped structure design of the feed guide rail provides better guidance for the sliding of the copper tube. The continuous undulation formed by the wave-shaped structure can effectively guide the copper tube to slide along the predetermined trajectory, reducing the swaying and deviation of the copper tube during the feeding process. The reasonable design of the peak height and wavelength ensures the guiding effect while avoiding excessive wear on the surface of the copper tube. The continuously distributed wave-shaped structure provides continuous and stable guiding support, improving the feeding accuracy and stability.

[0020] Furthermore, the outer circumferential surface of the cutting blade is provided with a serrated structure, the tooth height of the serrated structure is 0.8mm to 1.5mm, the tooth pitch of the serrated structure is 2mm to 4mm, and the serrated structure is evenly distributed along the entire circumference of the cutting blade.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sawtooth structure design on the outer circumference of the cutting blade significantly improves the cutting ability and efficiency of the cutting blade. The multiple cutting points formed by the sawtooth structure can effectively disperse the cutting force, reduce the load of single-point cutting, and the reasonable design of tooth height and tooth pitch ensures the continuity and stability of cutting. The uniform distribution of the sawtooth structure along the entire circumference ensures the consistency of cutting quality, effectively reduces vibration and noise during the cutting process, and extends the service life of the cutting blade.

[0022] Furthermore, the number of the circular protrusions is at least 20, and the plurality of circular protrusions are equidistantly distributed on the surface of the support base, and the surface of the circular protrusions is provided with anti-slip texture.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by increasing the number of circular protrusions to at least 20 and distributing them equidistantly on the surface of the support base, the stability and vibration resistance of the device are further enhanced. The equidistant distribution of multiple protrusions ensures the uniform distribution of the support force, effectively dispersing the weight and working load of the device. The anti-slip texture on the surface of the circular protrusions enhances the friction with the mounting surface, preventing the device from slipping during high-speed cutting. The multi-point support design improves the overall rigidity and working stability of the device. Compared with existing technologies, the beneficial effects of the intermittent feeding and cutting device for copper tubes provided by this utility model are as follows: This utility model, through an innovative intermittent feeding mechanism design, adopts an L-shaped feeding guide rail combined with a propulsion cylinder and a pusher plate structure, achieving precise quantitative feeding of copper tubes and effectively solving the problem of uneven feeding.

Specifically, the principle of this utility model is as follows: This utility model adopts a modular design concept, dividing the entire device into five main parts: a feeding mechanism, a cutting mechanism, a positioning mechanism, a transmission mechanism, and a support base. Each part has a clear function and works in coordination. The feeding mechanism provides a stable sliding channel for the copper tube through an L-shaped feeding guide rail. The V-shaped positioning groove on the guide rail matches the circular cross-sectional shape of the copper tube, achieving precise positioning and guidance. The pusher cylinder drives the pusher plate to move linearly along the guide rail. The concave arc-shaped front surface of the pusher plate matches the outer diameter of the copper tube, achieving uniform thrust distribution and ensuring the accuracy and stability of the feeding. The positioning mechanism adopts a semi-circular gripper design. The fixed gripper and the movable gripper are driven by a clamping cylinder to open and close, forming a complete circular clamping surface for precise clamping and positioning of the copper tube. The core of the cutting mechanism is a disc-shaped cutting blade, which is driven to rotate at high speed by a drive motor and a multi-stage gear transmission system to cut the copper tube. The coolant channel design inside the transmission shaft achieves internal cooling of the cutting blade, effectively reducing the cutting temperature and minimizing tool wear. The support base enhances stability through its circular protrusions, providing reliable support for the entire device. Precise positioning and timing control between the various mechanisms enable coordinated actions for intermittent feeding, precise positioning, and efficient cutting of the copper tube. Throughout the process, the feeding mechanism pushes the copper tube to the designated position, the positioning mechanism clamps and positions it, the cutting mechanism executes the cutting action, the transmission mechanism transmits power, and the support base ensures overall stability. All parts work together to form a complete cutting and processing system.

[0037] Before use, first perform a pre-start inspection of the equipment to ensure that all components are securely connected, the transmission system is well lubricated, and the cutting blade is correctly installed and sharp. After starting the equipment, the drive motor drives the transmission mechanism to start working, and the cutting blade begins to rotate at high speed. The operator places the copper tube to be cut at the starting position of the feed guide rail, and the copper tube naturally falls into the V-shaped positioning groove, achieving initial positioning. The push cylinder is activated, and the pusher plate begins to move forward, pushing the copper tube along the guide rail to the predetermined cutting position. When the copper tube reaches the cutting position, the clamping cylinder is activated, and the movable jaw moves towards the fixed jaw, firmly clamping the copper tube in the positioning fixture. After confirming that the copper tube is firmly clamped, the cutting action is started. The cutting blade rotates at high speed under the drive motor, and at the same time, the blade is cooled by the coolant channel inside the transmission shaft. The cutting blade gradually cuts into the copper tube, completing the cutting action. After cutting, the cutting blade returns to the safe position, the clamping cylinder is released, the movable jaw opens, and the cut copper tube segment is removed from the positioning fixture. The cylinder is reset, and the pusher plate returns to its starting position, ready for the next cutting cycle. Throughout the operation, operators must pay attention to safety precautions, wear protective equipment, strictly follow the operating procedures, regularly check the equipment status, add coolant as needed, and maintain the equipment in good working condition.
