Technical Field
[0001] This utility model relates to the field of capillary copper tube cutting technology, specifically a capillary copper tube cutting machine. Background Technology
[0002] Capillary copper tubes are precision tubular industrial products made of copper and copper alloys, with an outer diameter ranging from 0.5 to 3 mm and an inner diameter ranging from 0.3 to 2.5 mm. Based on precision level, they can be divided into ordinary grade (general instruments and meters), higher grade (high-precision electronics industry), and precision grade (refrigeration devices for refrigerators / freezers). The smallest diameter produced through processes such as casting, extrusion, and rolling can reach Ф1.6 mm. This product features accurate and stable flow, strong corrosion resistance, and excellent thermal conductivity. During the production process, capillary copper tubes typically require cutting. However, it is inconvenient to cut capillary copper tubes to the required length according to demand. Furthermore, since the last remaining section after cutting often does not meet the required cutting length, common capillary copper tube cutting machines cannot easily separate and collect this section from the cut-to-length copper tubes.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0019] This utility model provides a capillary copper tube cutting machine. According to the cutting length requirement, the limiting frame is pushed by the first electric telescopic rod to adjust the distance between the proximity switch and the cutting mechanism. It is used for fixed-length cutting adjustment of capillary copper tubes. When the last remaining capillary copper tube does not reach the cutting length requirement, the guide frame is slid and adjusted in the chute by the sixth electric telescopic rod, so that the last remaining capillary copper tube falls and slides to another receiving position through the guide frame.
[0020] Figures 1-5 The diagram shown is an overall structural schematic of one embodiment of the capillary copper tube cutting machine of this utility model. Please refer to [link / reference]. Figures 1-5 A capillary copper tube cutting machine according to this embodiment includes a frame 1. A cutting frame 2 is fixedly installed on the upper end of the frame 1 near the right side. A first support plate 3 is fixedly installed on the upper end of the frame 1 near the left side. A first lead screw 4 is rotatably connected to the right side of the first support plate 3. The left end of the first lead screw 4 is connected to the output shaft of a first motor 5. A movable pusher 6 is provided through the first lead screw 4. The first motor 5 and the first lead screw 4 cause the movable pusher 6 to move and adjust on the first lead screw 4 for capillary copper tube cutting feed.
[0021] The frame 1 includes a first electric telescopic rod 101 that runs through the inside of the frame 1. The right end of the first electric telescopic rod 101 is fixedly connected to a limit frame 102. A proximity switch 103 is installed through the limit frame 102. An opening groove 104 is opened through the side wall of the limit frame 102 near the bottom. A guide frame 105 is installed through the opening groove 104. The guide frame 105 is slidably connected to the limit frame 102 through a sliding groove 106. The sliding groove 106 is opened at the bottom of the opening groove 104. A sixth electric telescopic rod 107 is fixedly connected to the front side of the guide frame 105. The sixth electric telescopic rod 107 is installed on a second support frame 108. The second support frame 108 is fixedly installed on the front side of the limit frame 102.
[0022] According to the cutting length requirement, the limit frame 102 is pushed by the first electric telescopic rod 101, thereby adjusting the distance between the proximity switch 103 and the cutting mechanism 205. A laser rangefinder can be installed at an appropriate position on the cutting frame 2 to measure and control the adjustment of the position distance of the limit frame 102. For convenient and accurate measurement, the distance between the laser rangefinder and the cutting wheel of the cutting mechanism 205 is known and fixed, or the laser emission end of the laser rangefinder and the cutting wheel of the cutting mechanism 205 are on the same straight line. The laser rangefinder is an existing technology structure used for fixed-length cutting and adjustment of capillary copper tubes. When the last remaining capillary copper tube does not meet the cutting length requirement, the guide frame 105 is slid and adjusted in the chute 106 by the sixth electric telescopic rod 107, so that the last remaining capillary copper tube falls and slides through the guide frame 105 to another receiving position for separate unloading and collection. There are two receiving positions below the frame 1. The right receiving position is for qualified products, and the left receiving position is for unqualified products with insufficient length.
[0023] The cutting frame 2 includes a second lead screw 201 rotatably connected to the inner wall of the cutting frame 2. One end of the second lead screw 201 passes through the cutting frame 2 and is connected to the output shaft of the second motor 202. A movable frame 203 is provided through the second lead screw 201. The cutting frame 2 also includes a second electric telescopic rod 204 fixedly provided at the lower end of the movable frame 203. A cutting mechanism 205 is fixedly provided at the lower end of the second electric telescopic rod 204.
[0024] After the capillary copper tube on one side is cut, under the action of the second motor 202 and the second lead screw 201, the moving frame 203 moves and adjusts on the second lead screw 201, which can cut and process the capillary copper tube clamped and fixed on the other side, which helps to make the cutting process continuous. That is, there are two moving push frames 6. The front moving push frame 6 is used for cutting and feeding the clamped capillary copper tube, and the rear moving push frame 6 clamps and fixes the capillary copper tube for processing. After the processing of the front side is completed, the processing of the rear side is carried out. At the same time, the capillary copper tube is clamped on the front moving push frame 6 for processing. Each moving push frame 6 corresponds to two sets of third electric telescopic rods 207 and clamps 208. The two sets of clamps 208 are located in the left and right directions of the cutting wheel of the cutting mechanism 205, respectively.
[0025] The cutting frame 2 also includes a fixed frame 206 fixedly installed on the inner wall of the cutting frame 2 near the bottom. A third electric telescopic rod 207 is installed through the inside of the fixed frame 206. A clamp 208 is fixedly connected to the inner end of the third electric telescopic rod 207. A support roller 209 is rotatably connected between the inner walls of the fixed frame 206. The support roller 209 is installed on the left and right sides of the clamp 208.
[0026] Under the action of the third electric telescopic rod 207 and the clamp 208, the capillary copper tube is clamped and fixed on both sides of the cutting point of the capillary copper tube, that is, on both sides of the cutting wheel of the cutting mechanism 205, to enhance the stability during cutting and prevent the shaking during the cutting process from affecting the cutting effect. The support roller 209 is used to support the capillary copper tube during feeding.
[0027] The movable push frame 6 includes a first bracket 601 fixedly installed on the upper end of the movable push frame 6. A fourth electric telescopic rod 602 is fixedly installed on the inner top end of the first bracket 601. A pressure frame 603 is fixedly connected to the telescopic end of the fourth electric telescopic rod 602. The movable push frame 6 also includes a bracket 604 fixedly installed on the upper end of the movable push frame 6. The bracket 604 is located directly below the pressure frame 603.
[0028] The fourth electric telescopic rod 602 pushes the pressure frame 603 and the bracket 604 to clamp and fix one end of the capillary copper tube, which is used for the feeding of the capillary copper tube. The pressure frame 603, the bracket 604 and the inner wall of the clamp 208 are all provided with rubber or silicone pads to enhance the protection of the capillary copper tube clamping point.
[0029] The movable push frame 6 also includes a second bracket 605 fixedly installed on the left side of the movable push frame 6. A fifth electric telescopic rod 606 is fixedly installed through the left side of the second bracket 605. A connecting plate frame 607 is fixedly connected to the right telescopic end of the fifth electric telescopic rod 606. A top rod 608 is fixedly connected to the right side of the connecting plate frame 607 near the bottom.
[0030] The fifth electric telescopic rod 606 pushes the connecting plate frame 607. Under the action of the top rod 608, it pushes the end of the last remaining capillary copper tube located on the bracket 604, pushing it away from the bracket 604. It then moves to the right at the support roller 209 and falls onto the guide frame 105. The fixed frame 206 is provided with a knife groove and a receiving groove. The support roller 209 and the clamp 208 are both located in the receiving groove. The receiving groove and the knife groove are set vertically. The bottom of the receiving groove is set as an inclined surface, tilting to the right. When the last remaining capillary copper tube is short, it may not be able to move over the support roller 209 and fall onto the guide frame 105. In this case, the copper tube falls into the receiving groove and slides to the right onto the guide frame 105. If there are some reasons, the copper tube may remain in the receiving groove, which requires the staff to check and clean it regularly.
[0031] Combination Figures 1-5 The capillary copper tube cutting machine of this embodiment is used as follows: The fourth electric telescopic rod 602 pushes the pressure frame 603 to cooperate with the bracket 604 to clamp and fix one end of the capillary copper tube, which is used for the capillary copper tube feeding. According to the cutting length requirement, the limit frame 102 is pushed under the action of the first electric telescopic rod 101, thereby adjusting the distance between the proximity switch 103 and the cutting mechanism 205. The first motor 5 and the first lead screw 4 cause the moving push frame 6 to move and adjust on the first lead screw 4 for capillary copper tube cutting feed. When the capillary copper tube feed moves to the detection range of the proximity switch 103, the capillary copper tube feed reaches the cutting length requirement. The cutting mechanism 205 is pushed by the second electric telescopic rod 204 to cut. Under the action of the third electric telescopic rod 207 and the clamp 208, the capillary copper tube is clamped and fixed on both sides of the cutting point of the capillary copper tube, that is, on both sides of the cutting wheel of the cutting mechanism 205. To enhance stability during cutting and prevent vibration from affecting the cutting effect, the support roller 209 is used to support the capillary copper tube during feeding. When the proximity switch 103 does not detect the capillary copper tube within its detection range, the length of the remaining capillary copper tube will not meet the cutting requirements. The sixth electric telescopic rod 107 drives the guide frame 105 to slide and adjust within the slide groove 106, so that the remaining capillary copper tube falls through the guide frame 105 to another receiving position for separate feeding and collection. After the capillary copper tube on one side is cut, the moving frame 203 moves and adjusts on the second lead screw 201 under the action of the second motor 202 and the second lead screw 201, which can cut and process the capillary copper tube clamped and fixed on the other side, which helps to make the cutting process continuous. The cutting device is controlled by a central processing unit, which is an existing technology structure and the model of the central processing unit is S7-1500. Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
