Description

Technical Field

[0001] The invention relates to the technical field of thermal pipe shearing, in particular to a thermal pipe shearing device and a shearing method thereof. Background Art

[0002] Thermal pipes are a type of pressure pipes, which are generally used in heating, ventilation, air conditioning and industrial gas fields. They transport heat energy through the internal medium, thereby transporting heat from one point to another for release, thereby realizing the transfer of heat energy. The thermal medium generally used is hot water or hot steam. Steam pipes are divided into saturated steam pipes and superheated steam pipes, and hot water pipes are divided into low-temperature water pipes and high-temperature water pipes.

[0003] In the existing pipe cutting device, the cutting length needs to be controlled manually, which means that the pipe needs to be positioned before each cutting. The pipe cannot be positioned quickly, and the slow positioning speed will extend the preparation time before each cutting, causing the overall production rhythm to slow down. In large-scale production, this will significantly reduce the number of pipes cut per unit time and affect the production progress. Summary of the invention

[0011] In one embodiment of the present invention, a shearing preprocessing mechanism is installed on the side of the mounting plate, and the shearing preprocessing mechanism includes a power box, and the power box is fixedly installed on the side of the mounting plate.

A downward pressure head is fixedly installed on the end of the connecting rod, and the downward pressure head is arranged directly above the top shearing knife.

[0014] A thermal pipe shearing method is applicable to a thermal pipe shearing device, and the steps are as follows: S1: The motor drives the two power shafts to rotate in opposite directions through the power assembly. When the correction wheel rotates, the rotating correction wheel drives the rotating rod to rotate eccentrically, thereby causing the sliding plate to slide up and down inside the fourth sliding groove.

The rotation of the third gear can drive the rotating block to rotate, and the rotation of the rotating block can drive the cushion block to rotate, so that the cushion block can rotate to the top of the top shearing knife; S5: When the pipe is sheared, the cushion block is pressed downward, so that the third gear and the rotating block move downward at the same time. When the rotating block moves downward, the slide cylinder moves downward on the surface of the third slide rod, thereby compressing the third spring; S6: After the pipe cutting is completed, the push plate returns to its original position under the action of the fixed plate, and the double-toothed plate drives the third gear to rotate in the opposite direction, so that the rotating block and the cushion block can return to their original position under the action of the return spring.

[0015] The invention provides a thermal pipe shearing device, which has the following beneficial effects: 1. The present invention can quickly position the pipe by setting the positioning shearing mechanism, significantly shorten the preparation time before each shearing, and accurately determine the position of the pipe to ensure that the pipe can be sheared at a precise position each time, thereby ensuring that the dimensional parameters of the pipe such as the shearing length and the incision position meet the design requirements and improve the dimensional accuracy of the product.

[0016] 2. The present invention sets a shearing mechanism so that the shearing length of the pipe remains fixed during the entire processing process, without frequent manual intervention or frequent adjustments due to length deviations. This makes the production process smoother and reduces equipment downtime, which not only increases production speed but also reduces labor costs, thereby improving overall production efficiency.

[0017] 3. The present invention can correct the pipe before shearing by setting a shearing pretreatment mechanism. If the pipe is bent, deformed, etc., the incision will be uneven due to uneven force during shearing. After correction, the pipe is in a more ideal straight line state. During the shearing process, the blade contacts the pipe evenly, and a smoother incision can be obtained, which is beneficial to subsequent processing and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0022] Reference Figure 1-Figure 10The technical scheme provides a thermal pipe shearing device, which specifically includes a material transport platform 1, a positioning shearing mechanism 2 is installed on the top of the material transport platform 1, and the positioning shearing mechanism 2 includes a first sliding groove 201, a support plate 202, a slide rail 204 and a second sliding groove 206. The first sliding groove 201 is opened on the top of the material transport platform 1, and the first sliding groove 201 is provided with two, the support plate 202 is fixedly installed on the top of the material transport platform 1, a cross plate 203 is fixedly installed on the top of the support plate 202, the slide rail 204 is opened on the side of the cross plate 203, and a fixed plate 205 is slidably installed inside the slide rail 204, the second sliding groove 206 is opened on the top of the cross plate 203, and a push plate 207 is slidably installed inside the second sliding groove 206, and the push plate 207 and the fixed plate 205 is fixedly connected, a first mounting seat 208 is slidably installed on the top of the material transport platform 1, a first rotating shaft 209 is rotatably installed inside the first mounting seat 208, a first gear 210 is fixedly installed on the surface of the first rotating shaft 209, two first gears 210 are provided, baffles 211 are slidably installed inside the two first sliding grooves 201, a first tooth plate 212 is fixedly installed on the side of the baffle 211, and the first tooth plate 212 is meshed with the first gear 210. When the staff needs to cut the pipe, the pipe is placed on the entire device, and the pipe pushes the baffle 211 while moving, so that the baffle 211 slides inside the first sliding groove 201, and the sliding of the baffle 211 can drive the first tooth plate 212 to move. The first gear 210 can be driven to rotate, and the rotating first gear 210 can drive the first rotating shaft 209 to rotate. The arrangement of the two baffles 211 enables the entire device to cut two pipes at the same time, thereby increasing the processing efficiency. In addition, the staff can change the cutting length of the pipe by adjusting the position of the first mounting seat 208 on the material transporting platform 1. A third sliding groove 213 is provided at the bottom of the cross plate 203, and a second tooth plate 214 is slidably installed inside the third sliding groove 213. The second tooth plate 214 is fixedly connected to the fixed plate 205. A second gear 215 is fixedly installed on the surface of the first rotating shaft 209, and the second gear 215 meshes with the second tooth plate 214. The top of the cross plate 203 is fixed A second mounting seat 216 is fixedly installed, and a first slide bar 217 is fixedly installed on the side of the second mounting seat 216. The fixing plate 205 is slidably connected with the first slide bar 217. The surface of the first slide bar 217 is sleeved with a first spring 218. The first spring 218 is arranged between the fixing plate 205 and the second mounting seat 216. When the first rotating shaft 209 rotates, the second gear 215 can be driven to rotate. The rotation of the second gear 215 can make the second tooth plate 214 slide inside the third sliding groove 213. The movement of the second tooth plate 214 can drive the fixing plate 205 to move, so that the fixing plate 205 slides on the surface of the first slide bar 217. When the fixing plate 205 moves, the first spring 218 is stretched.The first spring 218 generates elastic potential energy. When the pipe is cut, the baffle 211 is no longer squeezed. Then, under the action of the elastic potential energy of the first spring 218, the fixing plate 205 is restored to its original position to cope with the next processing. By setting the positioning shearing mechanism 2, the pipe can be quickly positioned, which significantly shortens the preparation time before each cutting. The position of the pipe can also be accurately determined to ensure that the pipe can be cut at a precise position each time, thereby ensuring that the dimensional parameters of the pipe such as the cutting length and the incision position meet the design requirements and improve the dimensional accuracy of the product.

[0023] Reference Figure 1-Figure 10The present embodiment further proposes that a shearing mechanism 3 is installed on the side of the material transporting platform 1, and the shearing mechanism 3 includes a mounting plate 301, and the mounting plate 301 is fixedly mounted on the side of the material transporting platform 1. A second sliding bar 302 is fixedly mounted on the top of the mounting plate 301. The second sliding bar 302 is provided with two groups, and each group of second sliding bars 302 is provided with two. Top shearing knives 303 are slidably installed on the surfaces of the two groups of second sliding bars 302. A bottom shearing knife 304 is fixedly installed on the bottom of the mounting plate 301. There are two bottom shearing knives 304. The downward pressure of the top shearing knife 303 can shear the pipe. The surfaces of the two groups of second sliding bars 302 are sleeved with second springs 305. The second springs 305 are arranged between the mounting plate 301 and the top shearing knife The top of the mounting plate 301 is fixedly installed with a fixed block 306, two fixed blocks 306 are provided, and the tops of the two fixed blocks 306 are fixedly installed with a third slide bar 307, and the surface of the third slide bar 307 is slidably installed with a slide cylinder 308, and the surface of the third slide bar 307 is sleeved with a third spring 309, and the third spring 309 is provided between the slide cylinder 308 and the fixed block 306, and the top of the slide cylinder 308 is rotatably installed with a rotating block 310, and the top of the rotating block 310 is fixedly installed with a third gear 311, and the side of the push plate 207 is fixedly installed with a double tooth plate 312, and the double tooth plate 312 is meshed with the third gear 311, and the surface of the rotating block 310 is fixedly installed with a cushion block 313, and the top of the mounting plate 301 is fixedly installed with a The triangular rod 314 is provided with a return spring 315 between the triangular rod 314 and the cushion block 313. When the push plate 207 moves under the action of the fixed plate 205, the double-toothed plate 312 can be driven to move, and then the third gear 311 can be driven to rotate. The rotation of the third gear 311 can drive the rotating block 310 to rotate. The rotation of the rotating block 310 can drive the cushion block 313 to rotate, so that the cushion block 313 can be rotated to the top of the top shearing knife 303. At the same time, the rotation of the cushion block 313 also stretches the return spring 315. When the pipe is sheared, the cushion block 313 is pressurized downward, so that the third gear 311 and the rotating block 310 move downward at the same time. When the third gear 311 is moved, the slide cylinder 308 can be moved downward on the surface of the third slide rod 307, thereby compressing the third spring 309. After the pipe cutting is completed, the push plate 207 returns to its original position under the action of the fixed plate 205, and the double-toothed plate 312 drives the third gear 311 to rotate in the opposite direction, so that the rotating block 310 and the cushion block 313 can return to their original positions under the action of the return spring 315. When the length of the pipe to be cut is short, the double-toothed plate 312 and the third gear 311 are always kept in meshing state, so the cushion block 313 can be returned to its original position only by the double-toothed plate 312. When the length of the pipe to be cut is long, when the double-toothed plate 312 returns, the double-toothed plate 312 will finally separate from the third gear 311.Therefore, the cushion block 313 can be returned by the return spring 315. By setting the shearing mechanism 3, the shearing length of the pipe is kept fixed during the entire processing process, without frequent manual intervention or frequent adjustments due to length deviations. This makes the production process smoother and reduces the downtime of the equipment, which not only improves the production speed, but also reduces the labor cost, thereby improving the overall production efficiency.

[0024] Reference Figure 1-Figure 10The present embodiment further proposes that a shearing pretreatment mechanism 4 is installed on the side of the mounting plate 301, and the shearing pretreatment mechanism 4 includes a power box 401, the power box 401 is fixedly installed on the side of the mounting plate 301, a bottom plate 402 is fixedly installed on the side of the power box 401, the bottom plate 402 is fixedly connected to the bottom of the bottom shearing knife 304, a bracket 403 is fixedly installed on the side of the bottom plate 402, a correction seat 404 is fixedly installed on the top of the bracket 403, the pipe is placed on the top of the correction seat 404, a motor 405 is fixedly installed inside the power box 401, a power shaft 406 is rotatably installed inside the power box 401, two power shafts 406 are provided, the motor 405 is connected to the power shaft 406 through a power assembly, and the power assembly The components include a gear set and a pulley set, which transmit the power. This is the prior art and there is no need to elaborate here. The motor 405 causes the two power shafts 406 to rotate in opposite directions through the power assembly. The power shafts 406 penetrate the outside of the power box 401. Correction wheels 407 are fixedly installed at both ends of the two power shafts 406. The setting of the correction wheel 407 can not only correct the pipe, but also provide forward thrust for the pipe. A rotating rod 408 is rotatably installed on the surface of the top correction wheel 407. The rotating rod 408 is set at the eccentric position of the correction wheel 407. A side plate 409 is fixedly installed on the top of the power box 401. Two side plates 409 are set. The inside of the two side plates 409 is provided with a fourth sliding groove 410. The fourth sliding groove A sliding plate 411 is slidably installed inside the groove 410, and the sliding plate 411 is rotatably connected to the rotating rod 408. A connecting rod 412 is fixedly installed on the surface of the sliding plate 411, and a lower pressure head 413 is fixedly installed on the end of the connecting rod 412. The lower pressure head 413 is arranged directly above the top shearing knife 303. When the correction wheel 407 rotates, the rotating correction wheel 407 can drive the rotating rod 408 to rotate eccentrically, thereby making the sliding plate 411 slide up and down inside the fourth sliding groove 410. The up and down sliding of the sliding plate 411 can drive the connecting rod 412 to slide up and down, thereby driving the lower pressure head 413 to reciprocate up and down motion. In a static state, the up and down motion of the lower pressure head 413 will not affect the The top shearing knife 303 is extruded, and the lower pressure head 413 does not contact the top shearing knife 303. However, when the cushion block 313 rotates to the top of the top shearing knife 303, the cushion block 313 is inserted between the lower pressure head 413 and the top shearing knife 303, and the lower pressure head 413 moves to the closest distance to the top shearing knife 303. At this time, this distance is smaller than the height of the cushion block 313. Therefore, when the cushion block 313 rotates to the top of the top shearing knife 303, the downward pressure of the lower pressure head 413 is transmitted to the top of the top shearing knife 303 through the cushion block 313, so that the top shearing knife 303 can move downward, so that the pipe can be sheared. By setting the shear pretreatment mechanism 4, the pipe before shearing can be corrected.If the pipe is bent or deformed, the cut will be uneven due to uneven force during shearing. After correction, the pipe is in a more ideal straight line state. During the shearing process, the blade contacts the pipe evenly, and a smoother cut can be obtained, which is conducive to subsequent processing and assembly.

[0025] Reference Figure 1-Figure 10 This embodiment also proposes a thermal pipe shearing method, which is applicable to a thermal pipe shearing device, and the steps are as follows: S1: The motor 405 causes the two power shafts 406 to rotate in opposite directions through the power assembly. When the correction wheel 407 rotates, the rotating correction wheel 407 drives the rotating rod 408 to rotate eccentrically, thereby causing the sliding plate 411 to slide up and down inside the fourth sliding groove 410. The up and down sliding of the sliding plate 411 drives the connecting rod 412 to slide up and down, thereby driving the lower pressure head 413 to reciprocate up and down motion; S2: When the staff needs to cut the pipe, the pipe is placed on the entire device. The pipe pushes the baffle 211 while moving, and the sliding of the baffle 211 drives the first tooth plate 212 to move, thereby driving the first gear 210 to rotate, and the rotating first gear 210 drives the first rotating shaft 209 to rotate; S3: When the first rotating shaft 209 rotates, the second gear 215 rotates, causing the second tooth plate 214 to slide inside the third sliding groove 213. The movement of the second tooth plate 214 drives the fixed plate 205 to move, causing the fixed plate 205 to slide on the surface of the first sliding rod 217, and at the same time, the first spring 218 is stretched, causing the first spring 218 to generate elastic potential energy; S4: When the push plate 207 moves under the action of the fixed plate 205, the double-toothed plate 312 is driven to move, and then the third gear 311 is driven to rotate. The rotation of the third gear 311 can drive the rotating block 310 to rotate, and the rotation of the rotating block 310 can drive the cushion block 313 to rotate, so that the cushion block 313 can rotate to the top of the top shearing knife 303; S5: When the pipe is sheared, the cushion block 313 is pressed downward, so that the third gear 311 and the rotating block 310 move downward at the same time. When the rotating block 310 moves downward, the slide cylinder 308 moves downward on the surface of the third slide bar 307, thereby compressing the third spring 309; S6: After the pipe cutting is completed, the push plate 207 returns to its original position under the action of the fixed plate 205, and the double-toothed plate 312 drives the third gear 311 to rotate in the opposite direction, so that the rotating block 310 and the cushion block 313 can return to their original positions under the action of the return spring 315.

[0026] Specifically, the working process or working principle of the thermal pipe shearing device is as follows: when the staff needs to shear the pipe, the pipe is placed on the entire device, and the pipe pushes the baffle 211 while moving, so that the baffle 211 slides inside the first sliding groove 201, and the sliding of the baffle 211 can drive the first tooth plate 212 to move, and then drive the first gear 210 to rotate, and the rotating first gear 210 can drive the first rotating shaft 209 to rotate. The setting of the two baffles 211 enables the entire device to shear two pipes at the same time, thereby increasing the processing efficiency, and the staff can adjust the position of the first mounting seat 208 on the material transport platform 1 to The shearing length of the pipe is changed. When the first rotating shaft 209 rotates, the second gear 215 can be driven to rotate. The rotation of the second gear 215 can make the second tooth plate 214 slide inside the third sliding groove 213. The movement of the second tooth plate 214 can drive the fixed plate 205 to move, so that the fixed plate 205 slides on the surface of the first sliding rod 217. When the fixed plate 205 moves, the first spring 218 is stretched, so that the first spring 218 generates elastic potential energy. When the pipe is sheared, the baffle 211 is no longer squeezed, and under the action of the elastic potential energy of the first spring 218, the fixed plate 205 is restored to its original position to cope with the next processing.

[0027] When the push plate 207 moves under the action of the fixed plate 205, the double-toothed plate 312 can be driven to move, and then the third gear 311 can be driven to rotate, and the rotation of the third gear 311 can drive the rotating block 310 to rotate, and the rotation of the rotating block 310 can drive the cushion block 313 to rotate, so that the cushion block 313 can be rotated to the top of the top shearing knife 303, and the rotation of the cushion block 313 also stretches the return spring 315. When the pipe is sheared, the cushion block 313 is pressurized downward, so that the third gear 311 and the rotating block 310 move downward at the same time. When the rotating block 310 moves downward, the slide cylinder 308 can move downward on the surface of the third slide rod 307 The third gear 311 is pressed against the push plate 207 to move in a row, thereby compressing the third spring 309. After the pipe cutting is completed, the push plate 207 returns to its original position under the action of the fixed plate 205, and the double-toothed plate 312 drives the third gear 311 to rotate in the opposite direction, so that the rotating block 310 and the cushion block 313 can return to their original positions under the action of the return spring 315. When the length of the pipe to be sheared is short, the double-toothed plate 312 and the third gear 311 always remain in meshing state, so the cushion block 313 can be returned to its original position only by the double-toothed plate 312. When the length of the pipe to be sheared is long, when the double-toothed plate 312 returns, the double-toothed plate 312 will finally separate from the third gear 311, so the cushion block 313 can be returned to its original position by the return spring 315.

[0028] The motor 405 drives the power assembly to operate, and the motor 405 causes the two power shafts 406 to rotate in opposite directions through the power assembly. When the correction wheel 407 rotates, the rotating correction wheel 407 can drive the rotating rod 408 to rotate eccentrically, thereby causing the sliding plate 411 to slide up and down inside the fourth sliding groove 410. The up and down sliding of the sliding plate 411 can drive the connecting rod 412 to slide up and down, thereby driving the lower pressure head 413 to reciprocate up and down motion. In a static state, the up and down motion of the lower pressure head 413 will not cause the top shearing knife 303 to be impacted. During extrusion, the lower pressure head 413 will not contact the top shearing knife 303, but when the cushion block 313 rotates to the top of the top shearing knife 303, the cushion block 313 is inserted between the lower pressure head 413 and the top shearing knife 303, and the lower pressure head 413 moves to a distance from the top shearing knife 303 that is smaller than the height of the cushion block 313. Therefore, when the cushion block 313 rotates to directly above the top shearing knife 303, the downward pressure of the lower pressure head 413 is transmitted to the top of the top shearing knife 303 through the cushion block 313, so that the top shearing knife 303 can move downward, thereby shearing the pipe.
