The device includes a support frame horizontally movable above an operating table, driven by a first hydraulic cylinder; a slider horizontally slidable within the support frame, driven by a translation component, with the slider's sliding direction perpendicular to the support's moving direction; a second hydraulic cylinder positioned below the slider, its cylinder body connected to the lower surface of the slider; a first motor positioned below the second hydraulic cylinder, its upper end connected to the piston rod of the second hydraulic cylinder; a rotating box with its upper end connected to the power output end of the first motor, and a rotating component housed within the rotating box; and a second motor positioned outside the rotating box and connected to the rotating component, its power output end equipped with a cutting blade. The rotating component, through the second motor, drives the cutting blade to adjust its angle. This device has advantages such as multi-angle cutting and strong adaptability. In existing technologies, protective mechanisms should be installed during cutting to ensure worker safety and prevent injury from flying chips or chipped blades caused by improper operation. Utility Model Content

[0004] The purpose of this invention is to provide a cutting machine for producing tension clamps in order to solve the above-mentioned problems.

[0006] A cutting machine for producing tension clamps includes a main body with a positioning mechanism and a cutting mechanism. The main body also includes a protective mechanism. The main body includes an upper support, with two symmetrically arranged flip doors rotatably connected to its front end via a rotating shaft. The cutting mechanism includes an L-shaped support with a fixed baffle fixedly connected to it. A cutting blade is disposed within the fixed baffle. The protective mechanism includes a driving bevel gear fixedly connected to the top of the rotating shaft of each flip door. Two symmetrically arranged transmission prisms are rotatably connected to the inner side of the upper support. A driven bevel gear is fixedly connected to one end of each transmission prism, meshing with the driving bevel gear. A driving link is slidably connected to the transmission prism, and two symmetrically arranged lifting links are hinged to the other end of each driving link. A sliding ring is slidably connected to the lifting link, and a sliding baffle is rotatably connected to the bottom of the sliding ring. The sliding baffle is slidably connected to the fixed baffle and can cover the cutting blade.

[0007] Preferably, a connecting boss is fixedly connected to the bottom of the upper support, and a lower support is fixedly connected to the bottom of the connecting boss. A cavity is provided inside the connecting boss, and a hydraulic lifting rod is fixedly connected inside the lower support. A cutting platform is fixedly connected to the output end of the hydraulic lifting rod, and the cutting platform is slidably connected to the lower support.

[0008] Preferably, the bottom of the rotating shaft of the flip door is fixedly connected to a drive pulley, and two symmetrically arranged driven pulleys are rotatably connected inside the connecting boss. The driven pulleys and the drive pulley are connected by a synchronous belt. A limit plate is fixedly connected to the top of the driven pulleys, and the other end of the limit plate can extend out of the connecting boss.

[0009] Preferably, the positioning mechanism includes a longitudinal motor fixedly connected to the rear side of the upper bracket, a longitudinal screw rotatably connected to the top center of the upper bracket, the output end of the longitudinal motor being fixedly connected to the longitudinal screw, a sliding frame threaded onto the longitudinal screw, a transverse screw rotatably connected onto the sliding frame, a transverse motor fixedly connected to one end of the sliding frame, the output end of the transverse motor being fixedly connected to the transverse screw, a cutting bracket threaded onto the transverse screw, the cutting bracket being slidably connected to the sliding frame, the bottom of the cutting bracket being rotatably connected to the L-shaped bracket, and both ends of the sliding frame being rotatably connected to the drive linkage.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-10 As shown, a cutting machine for producing tension clamps includes a main body with a positioning mechanism and a cutting mechanism mounted on it. A protective mechanism is also provided on the main body. The main body includes an upper support 104, with two symmetrically arranged flip doors 103 hinged to its front end via a pivot. Each flip door 103 has an observation window covered with transparent material. The cutting mechanism includes an L-shaped support 402 with a fixed baffle 406 fixedly connected to it. A cutting blade 405 is disposed within the fixed baffle 406. The protective mechanism includes a driving bevel gear 304 keyed to the top of the pivot of each flip door 103. Two symmetrically arranged transmission prisms 306 are rotatably connected to the inner side of the upper support 104. One end of each transmission prism 306 is keyed to a driven bevel gear 305, which meshes with the driving bevel gear 304. A drive linkage 307 is slidably connected to each transmission prism 306. Two symmetrically arranged lifting links 308 are hinged to the other end of the moving link 307. A sliding ring 309 is slidably connected to the lifting link 308. A sliding baffle 310 is rotatably connected to the bottom of the sliding ring 309. The sliding baffle 310 is slidably connected to the fixed baffle 406. The sliding baffle 310 can cover the cutting blade 405. When the operator flips and opens the flip door 103, the flip door 103 drives the driving bevel gear 304 to rotate. The driving bevel gear 304 drives the driven bevel gear 305 to rotate. The driven bevel gear 305 drives the transmission prism 306 to rotate. The transmission prism 306 drives the driving link 307 to rotate. The driving link 307 drives the lifting link 308 to descend. The descending of the lifting link 308 drives the sliding ring 309 to descend. The sliding ring 309 drives the sliding baffle 310 to descend. The descending sliding baffle 310 covers the cutting blade 405. In this way, the operator will not cut their hand due to accidental contact when changing cutting materials.

[0031] The upper support 104 has a connecting boss 102 fixedly connected to its bottom. The lower support 101 is fixedly connected to the bottom of the connecting boss 102. A cavity is provided inside the connecting boss 102. A hydraulic lifting rod 106 is fixedly connected inside the lower support 101. A cutting platform 105 is fixedly connected to the output end of the hydraulic lifting rod 106. The cutting platform 105 holds the raw material to be cut. A clamping mechanism can be installed on the cutting platform 105 according to the material to be cut. The cutting platform 105 is slidably connected to the lower support 101. The positioning mechanism drives the cutting mechanism to move. The hydraulic lifting rod 106 drives the cutting platform 105 to rise and fall. The cutting platform 105 brings the raw material closer to the cutting blade 405, thus enabling the cutting of the raw material.

[0032] A drive pulley 301 is fixedly connected to the bottom of the rotating shaft of the flip door 103. Two symmetrically arranged driven pulleys 302 are rotatably connected inside the connecting boss 102. The driven pulleys 302 and the drive pulley 301 are connected by a synchronous belt. A limit plate 303 is fixedly connected to the top of the driven pulleys 302. The other end of the limit plate 303 can extend out of the connecting boss 102. When the flip door 103 flips open, it drives the drive pulley 301 to rotate. The drive pulley 301 drives the driven pulleys 302 to rotate. The driven pulleys 302 drive one end of the limit plate 303 to rotate out of the connecting boss 102. Therefore, when the cutting platform 105 is raised to carry out cutting work, the limit plate 303 cannot rotate out of the connecting boss 102, so the flip door 103 cannot be opened. This realizes the automatic locking of the flip door 103 during cutting, eliminating the possibility of workers opening the flip door 103 during cutting work, and better protecting workers.

[0033] The positioning mechanism includes a longitudinal motor 201 fixedly connected to the rear side of the upper bracket 104. A longitudinal screw 202 is rotatably connected to the top center of the upper bracket 104. The output end of the longitudinal motor 201 is fixedly connected to the longitudinal screw 202. A sliding frame 203 is threadedly connected to the longitudinal screw 202. A transverse screw 205 is rotatably connected to the sliding frame 203. A transverse motor 204 is fixedly connected to one end of the sliding frame 203. The output end of the transverse motor 204 is fixedly connected to the transverse screw 205. A cutting bracket 206 is threadedly connected to the transverse screw 205. The cutting bracket 206 is slidably connected to the sliding frame 203. The bottom of the cutting bracket 206 is rotatably connected to the L-shaped bracket 402. Both ends of the sliding frame 203 are rotatably connected to the drive connecting rod 307. The longitudinal motor 201 drives the longitudinal screw 202 to rotate. The rotation of the longitudinal screw 202 drives the sliding frame 203 to move longitudinally through the threaded connection. The transverse motor 204 drives the transverse screw 205 to rotate. The rotation of the transverse screw 205 drives the cutting bracket 206 to move laterally through the threaded connection. In this way, the cutting mechanism on the cutting bracket 206 can move freely in the transverse and longitudinal directions.

[0034] The cutting mechanism also includes a steering motor 401 fixedly connected to the cutting bracket 206. The output end of the steering motor 401 is fixedly connected to the L-shaped bracket 402. A cutting motor 403 is fixedly connected to one side of the L-shaped bracket 402. A mounting shaft 404 is rotatably connected to the L-shaped bracket 402. The mounting shaft 404 is fixedly connected to the output end of the cutting motor 403 and to the cutting blade 405. The steering motor 401 drives the L-shaped bracket 402 to rotate, and the L-shaped bracket 402 drives the cutting blade 405 to rotate, thus adjusting the cutting direction of the cutting blade 405. The cutting motor 403 drives the mounting shaft 404 to rotate, and the mounting shaft 404 drives the cutting blade 405 to rotate, which cuts the raw material.

[0035] Working principle: The longitudinal motor 201 drives the longitudinal screw 202 to rotate, and the rotation of the longitudinal screw 202 drives the sliding frame 203 to move longitudinally through a threaded connection. The transverse motor 204 drives the transverse screw 205 to rotate, and the rotation of the transverse screw 205 drives the cutting bracket 206 to move laterally through a threaded connection. In this way, the cutting mechanism on the cutting bracket 206 can move freely in the transverse and longitudinal directions. The steering motor 401 drives the L-shaped bracket 402 to rotate, and the L-shaped bracket 402 drives the cutting blade 405 to rotate, thus adjusting the cutting direction of the cutting blade 405. The cutting motor 403 drives the mounting shaft 404 to rotate, and the mounting shaft 404 drives the cutting blade 405 to rotate, which cuts the raw material. The hydraulic lifting rod 106 drives the cutting platform 105 to rise and fall, and the cutting platform 105 brings the raw material closer to the cutting blade 405, thus enabling the cutting of the raw material. The operator flips and opens the flip door 103, and the flip door 103 drives the active bevel gear 304 to rotate, and the active bevel gear... Gear 304 drives driven bevel gear 305 to rotate, driven bevel gear 305 drives transmission prism 306 to rotate, transmission prism 306 drives drive linkage 307 to rotate, drive linkage 307 drives lifting linkage 308 to descend, lifting linkage 308 descends and drives sliding ring 309 to descend, sliding ring 309 drives sliding baffle 310 to descend, sliding baffle 310 descends and covers cutting blade 405, so that workers will not cut their hands due to accidental contact when changing cutting materials, and the flip door 103 flips open. The drive pulley 301 rotates, which in turn drives the driven pulley 302 to rotate. The driven pulley 302 causes one end of the limiting plate 303 to rotate out of the connecting boss 102. Therefore, when the cutting platform 105 is raised to perform cutting work, the limiting plate 303 cannot rotate out of the connecting boss 102, so the flip door 103 cannot be opened. This achieves automatic locking of the flip door 103 during cutting, eliminating the possibility of workers opening the flip door 103 during cutting work and better protecting workers.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
