Description

Technical Field

[0001] This invention relates to the field of steel processing technology, specifically to a processing device for cutting steel. Background Technology

[0002] Steel refers to a metallic material with iron as the main component and a certain proportion of carbon and other elements added. It has high strength, good plasticity and toughness, and is widely used in construction, machinery, transportation and other fields. The steel pipe production process includes ironmaking, steelmaking, rolling and other steps, and finally forms products of various specifications, such as steel plates, steel bars and profiles. Steel pipes are a common type of steel. When using them, cutting equipment is needed to cut them. However, steel pipes are usually cylindrical. When the steel pipe is placed on the workbench, it is easily disturbed and shifted. The steel pipe needs to be redeployed before subsequent processing can be carried out, which wastes time and reduces the processing efficiency of steel pipe cutting. To address this, we propose a processing device for steel cutting. Summary of the Invention

[0011] Furthermore, the dust collection mechanism includes a rectangular box, which is located in the front area on the right side of the top outer wall of the base. A booster pump is fixed to the top of the rectangular box, and a flexible conduit is fixed at the center of the top of the booster pump.

[0013] The present invention has the following beneficial effects: 1. This invention, by setting a positioning mechanism, specifically by activating a push rod, pulls a square plate at its output end, causing the square plate to move away from the slide rod. At this time, the square plate pulls two sliders through connecting rod A, bringing the two sliders closer together. Then, motor A is activated, causing its output end to drive the lead screw to rotate, which in turn moves the front and back threaded blocks, bringing the two blocks closer together. Through connecting rod B, the pressure plate is pushed downward. In this way, the two sliders move closer together, causing the two clamping plates to move closer together. With the cooperation of the pressure plate, the steel pipe is clamped from the front, back, and top, positioning the steel pipe at the center of the top of the cover. This reduces the probability of the steel pipe rolling during cutting, reduces the time wasted on redeploying the steel pipe, and thus improves the processing efficiency of steel pipe cutting.

[0014] 2. This invention, by setting an adjustment mechanism, specifically, starts motor B to drive a gear to rotate, which in turn drives the rack on the left side to move, causing the rack on the left to move the square box C mounted on the top left and right. Then, motor C is started to drive a turntable to rotate, which in turn drives a rotating rod to rotate, causing the top front of the rotating rod and the rectangular block to slide along the inner wall of the cross groove, thus moving the square box C back and forth. In this way, the position of the square box C can be finely adjusted in all directions, moving the square box C and its top-mounted positioning mechanism to a position that is convenient for the cutting equipment to process, reducing the probability of the steel pipe obstructing the cutting process and thus ensuring that the steel pipe cutting work can proceed smoothly.

[0015] 3. This invention incorporates a dust collection mechanism, specifically by activating a booster pump installed at the bottom of a flexible conduit to create negative pressure within the conduit. This allows debris from circular saw cutting to be fed into a rectangular box through the flexible conduit. Once the rectangular box is full, the lever of the sliding plate is pushed downwards. As the sliding plate moves downwards, the insert rod is pulled out of the insert plate. The displacement of the sliding plate pulls the spring fitted on the outside of the insert rod, allowing the spring to accumulate potential energy and release the locking relationship between the rectangular box and the storage box. However, when the sliding plate is released, the insert rod is re-inserted into the insert plate by the spring's rebound, locking the rectangular box back into the storage box. This locking relationship facilitates workers to quickly remove the storage box for cleaning.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 As shown, the present invention is a processing device for steel cutting, including a base 11, a positioning mechanism 12, the positioning mechanism 12 being disposed on the top of the base 11, an adjustment mechanism 13 being disposed on the outside of the positioning mechanism 12, and a dust collection mechanism 14 being disposed on the top right side of the adjustment mechanism 13. The positioning mechanism 12 includes a base plate 121, a top cover 122 being fixed to the top of the base plate 121, pads 123 being fixed to the left and right sides of the top outer wall of the base plate 121, and drive units being fixed to the left and right sides of the inner wall of the top cover 122. The tops of the two pads 123 are arc-shaped surfaces, and the bottoms of the two pads 123 are welded to the left and right sides of the top outer wall of the top cover 122, respectively.

[0022] The push rod 1263 is activated, causing its output end to pull the square plate 1262, which moves away from the slide rod 124. At this time, the square plate 1262 pulls the two sliders 1251 through the connecting rod A1261, bringing the two sliders 1251 closer together. Then, the motor A129 is activated, causing its output end to drive the lead screw 1272 to rotate. The lead screw 1272 drives the front and back threaded blocks 1273 to move, bringing the two blocks 1273 closer together. Through the connecting rod B1282, the pressure plate 1281 is pushed downward. In this way, the two sliders 1251 move closer together, causing the two clamping plates 1252 to move closer together. With the cooperation of the pressure plate 1281, the steel pipe is clamped from the front, back and top, positioning the steel pipe at the center of the top of the cover. This reduces the probability of the steel pipe rolling during cutting, reduces the time wasted on redeploying the steel pipe, and thus improves the processing efficiency of steel pipe cutting.

[0023] The two drive groups have the same structure. Taking the drive group on the right as an example, the drive group includes a slide rod 124. The slide rod 124 is fixed on the left side of the top outer wall of the base plate 121. The front and rear sides of the outer wall of the slide rod 124 are respectively fitted with sliders 1251. The two sliders 1251 are slidably connected to the front and rear sides of the outer wall of the sliders 1251 respectively. A square plate 1262 is provided on the right side of the two sliders 1251 that are close to each other. The square plate 1262 is set on the top outer wall of the base plate 121. A push rod 1263 is provided at the center of the left side of the square plate 1262. The bottom of the push rod 1263 is fixed on the top outer wall of the base plate 121. The center of the right output end of the push rod 1263 is fixed at the center of the left outer wall of the square plate 1262.

[0024] The front and rear sides of the top outer wall of the square plate 1262 are rotatably connected to connecting rods A1261. The two connecting rods A1261 are horizontally mirrored with the square plate 1262 as the center. The two connecting rods A1261 are arranged in a V-shape. The left sides of the two connecting rods A1261 are close to each other, and the right sides are far apart from each other. The far sides of the two connecting rods A1261 are rotatably connected to the top of the two sliders 1251. The top of the top cover 122 has a straight groove. The top center of the two sliders 1251 is fixed with clamping plates 1252. The tops of the two clamping plates 1252 pass through the straight groove of the top cover 122 and extend upward. The two clamping plates 1252 are slidably connected to the inner wall of the straight groove of the top cover 122.

[0025] Flexible baffles 1264 are fixed to the side of the two clamping plates 1252 that are close to each other and the side of the two clamping plates 1252 that are close to the inner wall of the top cover 122, respectively. The side of the two clamping plates 1252 that are close to each other are flexibly connected by the flexible baffles 1264. C plates 1271 are respectively provided on the left and right sides of the top of the top cover 122. Side plates are fixed to the left and right sides of the two C plates 1271. Lead screws 1272 are respectively provided directly below the top outer wall of the two C plates 1271. The back of the two lead screws 1272 passes through the C plates 1271 and extends outward. Motors A129 are respectively fixed to the back of the two C plates 1271. The output ends of the front of the two motors A129 are respectively fixed at the center of the back of the two lead screws 1272.

[0026] Two lead screws 1272 are threaded to the front and rear sides of their outer walls, respectively, and pressure plates 1281 are respectively provided at the bottom of the two lead screws 1272. Four connecting rods B1282 are rotatably connected to the top of the two pressure plates 1281. The four connecting rods B1282 are divided into two groups of connecting rods, front and rear. Taking the connecting rod group located on the front as an example, the sides of the two connecting rods B1282 that are close to each other on the front are rotatably connected to the left and right sides of the block 1273 located on the front, respectively. The two pressure plates 1281 are slidably connected to the two C plates 1271, respectively.

[0027] The adjustment mechanism 13 includes a square box A131, which is located on the top of the base 11. A square box B132 is fixed to the bottom of the square box A131. A gear 1331 is rotatably connected to the top center of the square box B132. A rack 1332 is meshed with the left side of the gear 1331. The bottom of the gear 1331 extends downward and passes through the square box B132. A motor B1333 is fixed to the center of the bottom outer wall of the square box B132. The output end of the top of the motor B1333 is fixed to the bottom of the gear 1331. A protrusion is fixed to the top of the rack 1332. The protrusion of the rack 1332 extends upward and passes through the square box A131. A square box C1341 is located on the top of the square box A131. The bottom of the square box C1341 is fixed to the protrusion on the top of the rack 1332 located on the left side. A truss is fixed to the top of the square box A131. A circular saw is fixed on the truss.

[0028] Start motor B1333 to drive gear 1331 to rotate. Gear 1331 then drives rack 1332 on the left side to move, causing rack 1332 to move the top-mounted square box C1341 left and right. Then start motor C1343 to drive turntable 1352 to rotate, which in turn drives rotating rod 136 to rotate. The top front of rotating rod 136 and rectangular block 137 slide along the inner wall of cross groove 1351, causing square box C1341 to move back and forth. This allows for fine-tuning of the position of square box C1341, moving it and its top-mounted positioning mechanism 12 to a position that is convenient for the cutting equipment. This reduces the probability of steel pipe obstruction and interference with the cutting process, ensuring the smooth operation of steel pipe cutting.

[0029] A cross groove 1351 is provided at the top center of the square box C1341. A cross plate 1342 is provided at the center of the interior of the square box C1341. A motor C1343 is fixed at the bottom center of the cross plate 1342. A turntable 1352 is rotatably connected to the top center of the cross plate 1342. The bottom of the turntable 1352 is fixed to the top output end of the motor C1343. A square and round plate is fixed to the back of the turntable 1352. A rotating rod 136 is rotatably connected to the center of the square and round plate of the turntable 1352. The rotating rod 136 overlaps with the square and round plate of the turntable 1352. A rectangular block 137 is rotatably connected to the top of the outer wall of the back of the rotating rod 136. A cylinder is rotatably connected to the top of the outer wall of the front of the rotating rod 136. The cylinder of the rotating rod 136 is fixed to the bottom of the base plate 121. The cylinder of the rotating rod 136 and the rectangular block 137 are slidably connected to the inner wall of the cross groove 1351, respectively.

[0030] The dust collection mechanism 14 includes a rectangular box 141, which is located in the front area on the right side of the top outer wall of the base 11. A booster pump is fixed on the top of the rectangular box 141, and a flexible conduit 143 is fixed at the center of the top of the booster pump. The flexible conduit 143 extends from the right side of the front to the left side of the back and extends to the top of the truss. The flexible conduit 143 communicates with the interior of the rectangular box 141. A storage box 142 is inserted into the front of the rectangular box 141, and the interior of the storage box 142 communicates with the interior of the rectangular box 141. Insert plates 144 are fixed on the left and right sides of the storage box 142, respectively. The rectangular box 141 is fixed on the top of the square box A131.

[0031] The booster pump installed at the bottom of the flexible conduit 143 is activated to create negative pressure inside the flexible conduit 143. The debris generated by the circular saw cutting is fed into the rectangular box 141 through the flexible conduit 143. When the rectangular box 141 is full, the lever of the slide plate 146 is pushed down. The slide plate 146 moves downward and pulls the insertion rod 147 out of the insertion plate 144. The displacement of the slide plate 146 pulls the spring sleeved on the outside of the insertion rod 147. This allows the spring to accumulate potential energy and release the locking relationship between the rectangular box 141 and the storage box 142. However, when the slide plate 146 is released, the insertion rod 147 will be reinserted into the insertion plate 144 by the spring rebound, so that the rectangular box 141 is locked together with the storage box 142 again. This locking relationship makes it easy for the staff to quickly remove the storage box 142 for cleaning.

[0032] Locking boxes 145 are respectively provided on the back of the two insert plates 144. The sides of the two locking boxes 145 that are close to each other are fixed to the left and right sides of the outer wall of the insert plate 144, respectively. The front of the two locking boxes 145 are inserted into the back of the two insert plates 144, respectively. The sides of the two locking boxes 145 that are far apart from each other are respectively provided with transverse grooves. Slide plates 146 are slidably connected to the center of the interior of the two locking boxes 145. The sides of the two slide plates 146 that are far apart from each other pass through the transverse grooves of the two locking boxes 145 and extend outward. Insert rods 147 are respectively fixed at the top center of the two slide plates 146. The two insert rods 147 pass through the back of the two insert plates 144, respectively. Springs are sleeved on the outside of the two insert rods 147. The slide plates 146 are flexibly constrained to the inner wall of the locking boxes 145 by the springs.

[0033] In use, place the steel pipe on top of the top cover 122, ensuring its outer wall is in contact with the pad 123. Then, activate the two push rods 1263, causing their output ends to pull the square plate 1262. The square plate 1262 will move away from the slide rod 124, and then, through the two connecting rods A1261 rotatably connected at the top, the square plate 1262 will pull the two sliders 1251, causing them to slide. The two sliders 1251 will slide along the slide rod 124 towards each other, and then the sliders 1251 will drive the top fixed clamping plate 1252 to move, bringing the two clamping plates 1252 closer together and clamping the steel pipe. Then, activate... Motor A129 drives the lead screw 1272 to rotate, causing the lead screw 1272 to move the two threaded blocks 1273 on the front and back sides, bringing them closer together. This, in turn, pushes the pressure plate 1281 downwards via connecting rod B1282. The pressure plate 1281 slides downwards along the inner wall of plate C 1271 and presses the steel pipe downwards through its bottom arc surface, positioning the steel pipe on top of the top cover 122. This reduces the probability of displacement during cutting. Motor B1333 then drives gear 1331 to rotate, which in turn drives the rack 1332 on the left side to slide, thus moving the top-mounted... The square box C1341 moves back and forth, then the motor C1343 is started to drive the turntable 1352 to rotate. The rotation of the turntable 1352 then drives the rotating rod 136 at the center of the top of its square and round plates to rotate, causing the top front of the rotating rod 136 and the rectangular block 137 to slide along the inner wall of the cross groove 1351, causing the square box C1341 to move left and right. Then the truss is started to move the circular saw installed at the bottom, so that the circular saw cuts the steel pipe placed at the center of the top of the top cover 122. Then the booster pump installed at the bottom of the flexible conduit 143 is started to create negative pressure in the flexible conduit 143, so that the debris generated by the circular saw cutting is sucked into the flexible conduit 143. Then, the flexible conduit 143 will transport these debris into the rectangular box 141 and finally into the storage box 142. When the rectangular box 141 is full, the lever of the slide plate 146 is pushed down. The slide plate 146 moves down and pulls the insertion rod 147 out of the insertion plate 144. The displacement of the slide plate 146 pulls the spring sleeved on the outside of the insertion rod 147. This allows the spring to accumulate potential energy and release the locking relationship between the rectangular box 141 and the storage box 142. However, when the slide plate 146 is released, the insertion rod 147 will be reinserted into the insertion plate 144 by the spring rebound, so that the rectangular box 141 is locked together with the storage box 142 again. It should be noted that the control of push rod 1263, motor A129, motor B1333 and motor C1343 in this application can all be achieved by using the program set in the control panel and inputting relevant parameters as needed for automated control. The setting of this control method can be realized by existing technologies, such as PLC.
