Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-10The present invention provides a technical solution: a copper tube cutting device, comprising a workbench 100 and a limiting conveying mechanism 200 and a cutting mechanism 300 which are arranged on the workbench 100 in a left and right distribution, the limiting conveying mechanism 200 comprising a clamping mechanism 210 and a belt conveyor 220 mounted on the middle of the top surface of the clamping mechanism 210, the clamping mechanism 210 comprising a box body 2110, a cover shell 2120 and an opposing moving component 2130, and a servo motor 2140 fixedly mounted on the bottom of the box body 2110 for driving the opposing moving component 2130 and a clamping component 2150 mounted on the top of the cover shell 2120 and connected to the opposing moving component 2130, the cover shell 2120 is encapsulated on the top of the box body 2110 and encloses a receiving cavity for installing the opposing moving component 2130, the opposing moving component 2130 comprises a gear 2131 and two racks 2132 which are arranged opposite to each other and meshed with the gear 2131, the servo motor 2140 is fixedly mounted on the bottom of the box body 2110 and is driven by the opposing moving component 2130, and ... top of the cover shell 2120 and is connected to the opposing moving component 2130, the cover shell The output end of the motor 2140 passes through the box body 2110 and is fixedly connected to the gear 2131. The two inner side walls of the box body 2110 are provided with sliding grooves 2111 for sliding assembly of the rack 2132. The ends of the two racks 2132 away from the gear 2131 are provided with a support structure extending vertically inward and two connecting rods 2133 are vertically fixedly installed thereon. The cover shell 2120 is provided with four strip holes 2121 for the connecting rods 2133 to adapt and pass through. The clamping assembly 2150 includes two symmetrically distributed movable plates 2151, and the inner sides of the two movable plates 2151 are respectively fixedly connected with a plurality of first rubber bushings 2152 and a plurality of second rubber bushings 2153. The plurality of first rubber bushings 2152 and the plurality of second rubber bushings 2153 are arranged in sequence in an interlaced manner. The bottoms of the inner sides of the plurality of first rubber bushings 2152 and the plurality of second rubber bushings 2153 are all set as inclined surface structures.

[0054] Based on the above-mentioned structure, the copper tube cutting method and device are composed of a workbench 100, a limiting conveying mechanism 200 and a cutting mechanism 300, wherein the limiting conveying mechanism 200 is assembled on the middle of the workbench 100 surface, and is used for limiting the conveying of the copper tube to be cut and positioning during cutting, which is a pre-process for cutting. The cutting mechanism 300 is assembled on the right side of the workbench 100 surface, and is used for cutting the copper tube. Specifically, during the working process, the operator first uses a copper tube with the same specifications as the copper tube to be processed as a test tube. The sample is placed in the clamping assembly 2150 to adjust the clamping assembly 2150 to a state where the copper tube can be limited and transported. Under the rotation of the servo motor 2140, the gear 2131 drives the two racks 2132 to move toward each other along the two slide grooves 2111, and the two movable plates 2151 approach each other. A plurality of first rubber linings 2152 cooperate with a plurality of second rubber linings 2153 to interlace with each other and limit the copper tube sample, and the copper tube sample can move. At this time, the servo motor 2140 is turned off and the copper tube sample is moved. The sample is taken out. During the formal processing, the copper tube to be processed can be conveyed along with the belt conveyor 220 under the limit of the clamping assembly 2150. When the copper tube to be processed extends outward to the specified cutting length, the belt conveyor 220 stops running. At the same time, the clamping assembly 2150 is driven by the servo motor 2140 to tightly clamp the copper tube to achieve the positioning of the copper tube. Finally, the cutting mechanism 300 cuts the copper tube. After the cutting is completed, the clamping assembly 2150 is reset to the limit state. The subsequent copper tube to be processed Continue feeding to achieve continuous cutting. The copper tube cutting method and equipment, by setting a limited conveying mechanism 200 and adopting a belt conveyor 220, can realize horizontal feeding of copper tube raw materials. Under the limitation of the clamping component 2150, it can adapt to the transportation of copper tube raw materials of various lengths without affecting stability. At the same time, with the help of the opposite moving component 2130, the positioning and limiting of the copper tube raw materials can be quickly switched. In conjunction with the cutting mechanism 300, the continuous cutting operation of the copper tube raw materials can be completed, thereby improving the cutting efficiency.

[0055] Furthermore, the cutting mechanism 300 includes a top plate 310, two bases 320, and a saw blade 330. The top plate 310 is mounted above the two bases 320 and the two bases 320 are fixedly connected to the top plate 310 through two columns 340. The four columns 340 are externally slidably sleeved with a support plate 350 parallel to the top plate 310. The saw blade 330 is assembled on the support plate 350. A lifting cylinder 360 is fixedly mounted on the top of the top plate 310. A connecting frame 370 covered on the outside of the saw blade 330 is fixedly mounted on the top of the support plate 350. The output end of the lifting cylinder 360 passes through the top plate 310 and is fixedly connected to the connecting frame 370. The saw blade 330 cooperates with the lifting mechanism constructed by the top plate 310, the support plate 350, the connecting frame 370, the lifting cylinder 360, the two bases 320 and the four columns 340 to realize the lifting action, thereby realizing the cutting of the copper tube.

[0056] Furthermore, it also includes a feeding mechanism 400 assembled on the top of the workbench 100 and mounted on the left side of the limiting conveying mechanism 200. The feeding mechanism 400 includes a material table 410 and a feeding trough 420 arranged on one side of the material table 410 and distributed in an inclined direction. A pushing cylinder 430 is installed on the side of the material table 410 away from the limiting conveying mechanism 200, and a guide mechanism 440 is assumed to be provided on the side of the material table 410 away from the pushing cylinder 430. Among them, the feeding mechanism 400 is used for auxiliary feeding of copper tube raw materials, saving alignment operation. The copper tube to be cut is put into the feeding trough 420 and falls on the material table 410. With the help of the pushing cylinder 430, the copper tube can be pushed forward. With the help of the guiding mechanism 440, the alignment transition of the copper tube from the material table 410 to the limiting conveying mechanism 200 can be realized.

[0057] Furthermore, the material table 410 includes a plurality of first supports 4110, and the bottom of each of the first supports 4110 away from the feed trough 420 is provided with a slope structure 4120. The feed trough 420 includes a plurality of guide plates 4210, and each of the guide plates 4210 is welded to one side of each of the first supports 4110, and baffles 4220 are welded to the outer sides of the two outermost guide plates 4210. Among them, since there are various specifications of the length of copper tube raw materials, a material table 410 constructed by multiple first supports 4110 is used, in conjunction with multiple guide plates 4210, to effectively adjust the construction length of the feeding mechanism 400 to adapt to the feeding of copper tube raw materials of different length specifications. Specifically, the first supports 4110 and the guide plates 4210 can be prefabricated into an integrated structure. It should be noted that the two first supports 4110 located on the outermost side need to be additionally welded with baffles 4220 when welding with the guide plates 4210. Correspondingly, this prefabricated component with a unit module structure can adjust the overall construction length by adjusting the layout spacing, and the workbench 100 table top can be provided with T-slots or strip through holes to facilitate the adjustment and installation of prefabricated components bolted to the workbench 100.

[0058] Furthermore, the guide mechanism 440 includes a second support 4410 and two guide seats 4420 symmetrically arranged on the top of the second support 4410. Both sides of the top of the second support 4410 are provided with flanges 4430 extending vertically upward. The two flanges 4430 are threaded with screws 4440, and the inner ends of the two screws 4440 are rotatably connected to the two guide seats 4420. Among them, the guide mechanism 440 is mainly used for the copper tube raw material falling into the material table 410 to transition to the limiting conveying mechanism 200 in the middle, so as to ensure that the copper tube raw material is stably input into the clamping assembly 2150. The expansion structure is formed between the two guide seats 4420, which is helpful for the transition guidance of the copper tube. As a preferred embodiment, by providing the screw 4440, the operator can adjust the spacing between the two guide seats 4420 in real time, which is flexible to use. At the same time, it can adapt to the guiding operation of copper tubes with different radial specifications.

[0059] Furthermore, it also includes a length adjustment mechanism 500 assembled on the top of the workbench 100 and mounted below the cutting mechanism 300. The length adjustment mechanism 500 includes a screw slide 520 that is separated from the workbench 100 by two vertical plates 510, and a laser ranging sensor receiving end 530, a laser ranging sensor transmitting end 540 and an infrared sensor 550 that are all mounted on the top of the screw slide 520. The laser ranging sensor receiving end 530 and the laser ranging sensor transmitting end 540 are coaxially distributed along the length direction of the screw slide 520. The laser ranging sensor receiving end 530 is fixedly connected to one side of the top of the screw slide 520 through a fixed frame 560. A movable frame 570 is fixedly connected to the slide seat of the screw slide 520. The laser ranging sensor transmitting end 540 and the infrared sensor 550 are vertically distributed and mounted on the top of the movable frame 570. Among them, the length adjustment mechanism 500 mainly relies on the optical measurement principle to measure the fixed length of the copper tube to be cut and cooperates with the cutting mechanism 300 to achieve fixed-length cutting of the copper tube. It should be noted that during the installation and debugging of the laser distance sensor receiving end 530, it is necessary to ensure that the measuring point of the laser distance sensor receiving end 530 and the cutting surface where the saw blade machine 330 are located are in the same vertical plane, and correspondingly, the infrared sensor 550 and the laser distance sensor transmitting end 540 during the installation and debugging, that is, it is necessary to ensure that the measuring point of the laser distance sensor transmitting end 540 and the infrared sensor are in the same vertical plane. The axes of the sensors 550 are on the same horizontal line. Specifically, the copper tube to be cut is transported outward along with the limit conveying mechanism 200 until the infrared sensor 550 detects the end of the copper tube. Then the belt conveyor 220 stops running. At the same time, the clamping assembly 2150 is clamped. Under the action of the lifting cylinder 360, the saw blade 330 moves down and cuts the copper tube. At this time, the length of the cut copper tube corresponds to the length measured by the laser ranging sensor. When the length adjustment mechanism 500 is used, the operator can preset the cutting length of the copper tube through the screw slide 520.

[0060] Furthermore, a mounting hole 110 is provided in the middle of the workbench 100 for the servo motor 2140 to sink and penetrate, and a blanking hole 120 is provided on the right side of the workbench 100 and below the cutting mechanism 300. A discharge hopper 130 is provided at the bottom of the blanking hole 120. The discharge hopper 130 includes a shell 1310 with an upper and lower connecting structure, and a plurality of blanking plates 1320 are welded in the shell 1310, which are distributed along the inclined direction and are intermittently and relatively staggered. After the copper tube is cut, the cut copper tube will be output through the blanking hole 120. Preferably, by providing a discharge hopper 130, with the help of a plurality of blanking plates 1320, the blanking height can be reduced, and the cut copper tube can be prevented from falling directly, thereby forming an effective buffer for the copper tube, effectively protecting the copper tube, and reducing the probability of the copper tube being damaged due to collision during the blanking process. The blanking plate 1320 can be made of rubber material.

[0061] Furthermore, the cutting method comprises the following steps:

[0062] Step 1: The copper tube to be cut enters the limiting conveying mechanism 200 from the left side of the workbench 100, and is conveyed along the belt conveyor 220 under the limiting action of the clamping mechanism 210, and is finally cut by the cutting mechanism 300.

[0063] Step 2. In step 1, the copper tube can be loaded with the aid of the loading mechanism 400 . The cutting length of the copper tube can be adjusted with the aid of the length adjusting mechanism 500 . The cut copper tube is output through the blanking hole 120 .
