Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, and in particular to a copper tube cutting machine. Background Art

[0002] The copper tube cutting machine mainly clamps and positions the copper tube with a fixture, and then rotates it so that the copper tube contacts the cutting knife. The cutting knife then removes excess metal from the copper tube so that the copper tube can be cut into a desired shape. The existing copper tube cutting machine mainly chamfers the tube mouth of the copper tube, and can remove burrs on the edge of the tube mouth after the copper tube is cut. It is more accurate and beautiful than manual deburring.

[0003] When cutting a copper tube, if the copper tube is not clamped stably, the copper tube will be skewed, causing instability in the cutting of the copper tube. There will be problems such as inability to stably cut the copper tube, and excessive cutting of the copper tube, causing damage to the copper tube. In addition, because the cutting knife cuts the copper tube evenly when feeding, if the copper tube is skewed, when the copper tube rotates, it will cause varying impact forces on the cutting knife, affecting the service life of the cutting knife.

When the multiple arc-shaped protective plates 714 are close to each other, they will be combined into a circle, and the multiple protective plates 714 combined into a circle are kept in a concentric state with the stabilizing ring 73, such as Fig. 9 As shown, a side of the protective plate 714 away from the movable rod 711 is set as a chamfered slope, so that the protective plate 714 can be gradually opened when it hits the copper tube.

[0022] like Figures 1 to 5As shown, a support assembly for supporting the copper tube during cutting and clamping is arranged between the left side of the fixed frame 2 and the machine tool 1, and the support assembly includes two electric slide rails 51 fixedly connected to the upper surface of the machine tool 1 and located on the left side of the fixed frame 2, and a movable plate 52 is arranged on the two electric slide rails 51 for sliding and being driven together, and a push rod 53 is fixedly connected to a surface of a side of the movable plate 52 close to the fixed frame 2, and the push rod 53 is composed of a cylindrical rod and a thick disc, wherein the thick disc of the push rod 53 is located at the end of the cylindrical rod away from the movable plate 52, and a resistance plate 54 is sleeved on the outer side of the cylindrical rod of the push rod 53, and a connecting tube 55 is fixedly connected to the outer surface of the resistance plate 54 away from the movable plate 52, and the connecting tube 55 is sleeved on the outer side of the cylindrical rod of the push rod 53, and a rotating block 56 is sleeved on the end of the cylindrical rod of the push rod 53 away from the movable plate 52, and the end of the rotating block 56 away from the movable plate 52 abuts against the thick disc of the push rod 53, and the inner side surface of the rotating block 56 is opened. A limiting groove is provided, and a first spring 57 is fixedly connected between the end of the connecting tube 55 away from the abutment plate 54 and the limiting groove of the rotating block 56, a rolling groove is provided between the rotating block 56 and the cylindrical rod of the pushing rod 53, and a ball 58 is rollingly provided between the rotating block 56 and the rolling groove of the pushing rod 53, and the ball 58 is used to stabilize the rotating block 56 and stably rotate outside the cylindrical rod of the pushing rod 53. The outer surfaces of the connecting tube 55 and the rotating block 56 are both rotatably connected with a connecting rod 59, and the end of the connecting rod 59 away from the connecting tube 55 is rotatably connected to the supporting plate 510, and the end of the supporting plate 510 away from the connecting rod 59 is fixedly connected to the lifting rod 592, and the outer surface of the rotating block 56 is fixedly connected to the lifting tube 591, and the outer surface of the rotating block 56 is provided with a lifting groove corresponding to the position of the lifting tube 591, and the end of the lifting rod 592 away from the supporting plate 510 slides in the lifting tube 591 and the lifting groove, and the outer side surface of the support plate 510 is provided with a rough texture for contacting with the copper tube.

[0023] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The abutment plate 54 is not squeezed by the clamp 3 , and the abutment plate 54 does not stretch the first spring 57 through the connecting tube 55 . The connecting tube 55 does not unfold the support plate 510 through the connecting rod 59 , and the protective plate 714 is at the innermost side.

[0024] The working status is: The copper tube is placed in a horizontal and concentric position of the clamp 3, and the copper tube is within the clamping range of the clamp 31. The staff then contacts the outer ring surface of the copper tube through the clamp 31 to achieve clamping and positioning of the copper tube by the clamp 31. The clamp 31 is an existing structure and is not described in detail here. The motor 21 is started, and the output shaft of the motor 21 drives the gear 22 to rotate. The gear 22 drives the clamp 3 to rotate inside the fixed frame 2 through the gear ring 32, so that the clamp 3 drives the copper tube to rotate through the clamp 31. At this time, the electric telescopic rod 6 is pushed to make the cutting tool 61 gradually approach the copper tube. After the copper tube rotates and contacts with the cutting tool 61, the contact position between the copper tube and the cutting tool 61 will be removed by the cutting tool 61 to achieve the turning chamfering of the copper tube.

[0025] The support assembly supports the copper tube: Due to the characteristics of the copper tube material, the material characteristics are relatively soft, and the copper tube is hollow inside, so when the clamping jaws 31 clamp the copper tube, the copper tube is easily deformed, resulting in the clamping jaws 31 being unable to effectively clamp and position the copper tube.

[0026] When the clamping jaws 31 clamp the outer ring surface of the copper tube, the electric slide rail 51 can be started, and the electric slide rail 51 can drive the movable plate 52 to move inside the machine tool 1 to the side close to the clamp 3. When the movable plate 52 moves, it will drive the push rod 53 to move synchronously. The push rod 53 makes the rotating block 56 sleeved on its cylindrical rod move synchronously. The rotating block 56 makes the connecting rod 59 drive the support plate 510 to move inside the copper tube. When the support plate 510 quickly moves inside the copper tube to the clamping position of the clamping jaws 31, this When the push rod 53 continues to move, the movement of the push rod 53 will drive the rotating block 56 to continue to move due to the fitting action of the ball 58 rolling in the rolling groove between the push rod 53 and the rotating block 56. The rotating block 56 will stretch the first spring 57 between the connecting tube 55 and the rotating block 56 through its limiting groove. The movable block 56 pulls the support plate 510 through the lifting tube 591 and the lifting rod 592, and the support plate 510 pulls the connecting rod 59, so that the connecting rod 59 rotates to the side away from the contact plate 54 with the rotation connection point with the connecting tube 55 as the axis. At this time, the connecting rod 59 gradually rotates from the inclined state to the direction perpendicular to the connecting tube 55, and then the connecting rod 59 pushes the support plate 510 to expand outward during the rotation process. At this time, the support plate 510 moves away from the ball 58 in the lifting tube 591 and the lifting groove through the lifting rod 592. When one side slides, the support plate 510 is stably stretched outward, so that the support plate 510 can support the position where the copper tube is clamped by the clamp 31 from the inside, so as to prevent the copper tube from being deformed when the clamp 31 clamps the copper tube, thereby avoiding the problem that the deformed copper tube cannot be effectively clamped by the clamp 31, improving the stability of the clamp 31 clamping the copper tube, avoiding deformation and crookedness when the clamp 31 clamps the copper tube, which is beneficial to the cutting tool 61 to effectively chamfer the copper tube, and reducing the defective rate during the chamfering cutting of the copper tube.

[0027] Stabilization of copper pipes by stabilizing components: When cutting the copper tube, if the copper tube is not clamped stably, the copper tube will be skewed, causing instability in the cutting of the copper tube. There will be problems such as the inability to stably cut the copper tube, and there will also be problems such as excessive cutting of the copper tube, causing damage to the copper tube. In addition, because the cutting knife 61 cuts the copper tube evenly when feeding, if the copper tube is skewed, when the copper tube rotates, it will cause varying impact forces on the cutting knife 61, affecting the service life of the cutting knife 61.

[0028] When the cutting knife 61 is feeding, the telescopic shaft of the electric telescopic rod 6 will drive the connecting plate 71 to move synchronously, and the connecting plate 71 will drive the stabilizing ring 73 to move synchronously through the connecting frame 72. The stabilizing ring 73 will drive the stabilizing wheel 76 to move synchronously through the hinge seat 74 so that the rotating shaft 75 drives the stabilizing wheel 76 to move synchronously. At this time, the inclined surface of the protective plate 714 on the stabilizing component will first contact the copper tube, and then the protective plate 714 will move outward after its inclined surface contacts the copper tube. Fig. 9 As shown above, the protective plate 714 drives the movable rod 711 to move synchronously and compress the second spring 712. After the stabilizing assembly continues to move, the protective plate 714 will continue to move along the outer surface of the copper tube, and then the stabilizing wheel 76 will contact the outer ring surface of the copper tube. When the copper tube rotates, the stabilizing wheel 76 in contact with the copper tube will be driven by the copper tube to rotate synchronously when the copper tube rotates. Because the stabilizing ring 73 and the clamp 3 maintain a horizontal and concentric position, the multiple stabilizing wheels 76 at this time will be in contact with and fit the outer surface of the copper tube. The rolling contact support of the copper tube by the stabilizing wheel 76 can keep the rotation of the copper tube stable, thereby reducing the inability of the cutting knife 61 to cut the copper tube evenly due to the skewness of the copper tube. Ensuring the uniform cutting of the copper tube by the cutting knife 61 can avoid the impact of the copper tube on the cutting knife 61, thereby increasing the service life of the cutting knife 61.

[0029] Stabilizing components to remove the debris from copper tube cutting: During the process of the copper tube rotating the stabilizing wheel 76, the stabilizing wheel 76 drives the rotating shaft 75 to rotate, and the rotating shaft 75 drives the fan blades 77 to rotate. During the rotation of the fan blades 77, the debris from the copper tube cutting will be blown away to prevent the debris from accumulating on the cutting blade 61, thereby reducing the impact of the copper tube debris on the copper tube cutting and improving the efficiency of the copper tube cutting. In addition, the fan blades 77 can also cool the cutting blade 61 by blowing air, thereby preventing the cutting blade 61 from overheating when cutting the copper tube, thereby increasing the service life of the cutting blade 61.

[0030] The stabilizing component protects the copper tube from falling off: When cutting the copper tube, since the cutting knife 61 is a fixed feed knife, when the cutting knife 61 contacts and rotates the copper tube, if the copper tube is clamped unstably, the copper tube will become loose on the clamp 31, causing the copper tube to fall off the clamp 31. In the process of the copper tube falling off, the copper tube will be thrown out due to the high-speed rotation of the copper tube, which will cause danger to the staff operating the cutting knife 61.

[0031] During the rotation of the stabilizing wheel 76, the stabilizing wheel 76 will drive the second gear 78 to rotate synchronously through the rotating shaft 75, and the second gear 78 will drive the second gear ring 79 to rotate synchronously. During the rotation of the second gear ring 79, the movable rod 711 will be driven to rotate synchronously through the fixed plate 710. During the rotation of the movable rod 711, the movable frame 713 will be driven to rotate synchronously. The movable frame 713 will be thrown outward during the rotation, so that the movable frame 713 drives the movable rod 711 to move outward in the hole of the fixed plate 710, that is, Fig. 9 As shown above, the movable rod 711 will compress the second spring 712 again, and then the movable frame 713 will drive the protective plate 714 to move outward synchronously, so that the protective plate 714 will not affect the rotation of the copper tube, and at the same time avoid the problem of excessive wear of the protective plate 714 after long-term contact with the rotating copper tube. In addition, it can also avoid the problem of overheating caused by the contact and friction between the protective plate 714 and the rotating copper tube.

[0032] When the copper tube falls off, the rotation of the copper tube cannot effectively drive the stabilizing wheel 76 to rotate. The stabilizing wheel 76 stops rotating and the rotating shaft 75 stops rotating. The rotating shaft 75 stops rotating, so that the gear 2 78 no longer drives the gear ring 2 79 to rotate. At this time, the movable frame 713 is no longer thrown out, and the movable rod 711 moves downward in the hole of the fixing plate 710 under the elastic restoring action of the second spring 712. Fig. 9 As shown below, the movable rod 711 drives the movable frame 713 to move downward synchronously, and the movable frame 713 drives the protective plate 714 to move up and down, so that the protective plate 714 surrounds and clamps the copper tube, preventing the copper tube from falling off from the clamp 31 and being thrown out, which would cause the high-speed rotating copper tube to cause danger to the operating staff, thereby improving the safety of the staff. In addition, it can prevent the thrown copper tube from colliding with surrounding equipment, and can prevent the copper tube from being damaged after colliding with surrounding equipment, thereby ensuring the integrity of the copper tube.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
