Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, and specifically relates to a punching and cutting device for steel structure processing. Background Art

[0002] Steel members refer to steel structure composite members that can bear and transfer loads, which are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding. Steel members have comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution, and are widely used in industries such as building construction and railway construction. At present, during the production process of steel plates, in order to meet the splicing requirements, it is inevitable to perform punching and cutting processing on them. Generally, a punching and cutting device is used to cut the steel plates into steel structures of certain specifications, punch holes at designated positions on the steel structures according to requirements, and then apply them to various aspects of construction.

[0003] A punching and cutting device for steel structure processing according to the patent No. CN215091958U includes a working platform. The surface of the working platform is provided with an inner concave track, and a slider is arranged inside the inner concave track; a placement plate is fixedly installed above the slider. A spring is arranged inside the placement plate, and a side plate is arranged on one side of the spring; a steel plate is fixedly installed on the surface of the placement plate. The use of the inner concave track and the slider facilitates the transportation of the steel plate. The steel plate moves through the movement of the slider. The use of the inner concave track limits the movement position of the steel plate to avoid punching errors caused by skew during transportation. Through the use of the side plate and the spring, there is a certain elastic movement space, which is convenient for placing steel plates of different specifications, and at the same time clamps and fixes the steel plate to avoid shaking during punching and cutting due to insecure positioning, which affects the punching and cutting quality.

[0004] For the above related solutions, the above-mentioned clamping of the steel plate is realized through the cooperation of the placement plate, the side plate and the spring, and the cutting and drilling operations of the steel plate are realized through the cutter bar and the punching machine. After completing a single processing, the operator needs to manually control the slider to push the steel plate along the inner concave track for subsequent re-operation. However, in this process, the elastic clamping depends on the deformation of the spring to generate the clamping force, and it is easy to have a decrease in the clamping force under the vibration and impact during processing, resulting in the displacement and deviation of the steel plate, seriously affecting the positioning accuracy of cutting and drilling. Moreover, the manual intervention slider pushing mechanism not only increases the labor intensity, but also reduces the production line coordination efficiency due to inconsistent operation rhythms. And in the clamping - processing - pushing process, the equipment needs to be frequently started and stopped, resulting in a significant reduction in the actual effective processing time. The above problems lead to a low degree of automation of the punching and cutting device, unable to realize the continuous processing of steel plates, affecting the processing efficiency of steel plates, and at the same time it is difficult to ensure product quality. Summary of the Invention

[0008] At the top end inside the frame, a displacement mechanism for horizontally moving the steel plate is arranged. The displacement mechanism includes a gear set connected to the frame through a bearing and a support shaft connected to the frame and the support frame through a bearing. Between the gear set and the support shaft, a pulley group forming a transmission structure is connected. On the outer sides of the two gear sets, a displacement member is meshed and connected. At one end of the support shaft away from the displacement member, a helical gear disk A is slidably connected. On one side of the helical gear disk A, a helical gear disk B sleeved on the outer surface of the rotating shaft is meshed and connected.

[0010] Preferably, a bevel gear set is connected between the rotating shaft and the rotating column, and the bevel gear set includes a driving gear connected to the rotating column and a driven gear connected to the rotating shaft.

[0011] Preferably, a guide groove B is opened on the outer surface of the rotating shaft. On the inner surface of the movable plate, a guide member B forming a sliding structure with the guide groove B is arranged. The guide groove B includes an arc groove and annular grooves located at both ends of the arc groove.

[0012] Preferably, a vertical plate sleeved on the outer side of the rotating shaft is arranged at the top end of the support frame. At one end of the two vertical plates close to the movable plate, a reset spring is arranged.

[0013] Preferably, a disk is arranged at one end of the support shaft close to the pulley group. Between the disk and the helical gear disk A, a telescopic spring is connected.

[0014] Preferably, an adjustment mechanism is provided between the limiting plate A and the movable plate. The adjustment mechanism includes a threaded cylinder connected to the movable plate through a bearing and a lead screw welded to the limiting plate A, and the lead screw is in threaded connection with the threaded cylinder.

[0015] Preferably, a grooved cylinder is slidably connected to one end of the rotating shaft away from the vertical plate, and an electric push rod is installed between the grooved cylinder and the convex block on the surface of the rotating shaft.

[0016] Preferably, a clamping wheel that forms a clamping structure with the grooved cylinder is slidably connected to one end of the rotating shaft close to the vertical plate. A linkage wheel is slidably connected to the outer surface of the threaded cylinder, and a transmission belt is wound around the surfaces of the linkage wheel and the clamping wheel.

[0017] Preferably, a guiding telescopic rod is connected between the limiting plate A and the movable plate, and the guiding telescopic rods are symmetrically arranged on both sides of the threaded cylinder. A limiting plate B sleeved on the threaded cylinder and the guiding telescopic rod is provided on one side of the support frame close to the threaded cylinder, and a ball is rotatably connected to one end of the limiting plate B close to the linkage wheel.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the coordinated action of the limit and anti-deviation mechanism, the displacement mechanism and the adjustment mechanism, the precision, efficiency and adaptability of steel plate processing are comprehensively optimized. The limit and anti-deviation mechanism utilizes the sliding connection between the guiding member A and the rotating column and the transmission of the bevel gear set, and under the drive of the hydraulic cylinder, the limiting plate A moves horizontally to realize the rapid clamping of the steel plate. The clamping stability is greatly improved compared with the traditional spring clamping, and the cutting / drilling precision is significantly guaranteed; the displacement mechanism automatically completes the interval pushing of the steel plates during the return stroke of the hydraulic cylinder through the meshing of the helical gear disc, the linkage of the pulley group and the symmetric drive design, and the efficiency is greatly improved compared with manual operation. At the same time, the double driving force input ensures the stable operation of the displacement member and prolongs the service life of the components; the adjustment mechanism realizes the adaptive adjustment of the distance between the limiting plates A through the clamping of the grooved cylinder and the clamping wheel and the transmission of the threaded cylinder and the lead screw, so as to adapt to steel plates of different sizes. The three mechanisms are integrated and linked, while reducing manual intervention and improving the degree of automation, taking into account the optimization of processing continuity, greatly improving the comprehensive processing efficiency, and the whole process is driven by the same hydraulic system without the need for an independent power source.

[0019] 1. In the process of the hydraulic cylinder driving the transverse movement mechanism and the guide member A to move vertically downward, since the guide member A is slidably connected to the rotating column through the guide groove A, the rotating column rotates and drives the rotating shaft to rotate through the bevel gear set. Since the movable plate is slidably connected to the rotating shaft through the guide member B and the guide groove B, the movable plate and the limiting plate A move horizontally, so as to realize the quick and stable limiting of the steel plate through the limiting plate A, which is more stable and firm than the traditional elastic clamping, prevent displacement deviation during the cutting and drilling processes, ensure the quality of cutting and drilling, and no additional driving device is required for driving in this process, reducing energy consumption.

[0020] 2. In the process of the hydraulic cylinder driving the transverse movement mechanism and the guide member A to move vertically upward, the rotating column rotates and drives the rotating shaft and the helical gear B to rotate through the bevel gear set. Since the helical gear A is meshed with the helical gear B, and the gear set and the support shaft are linked through the pulley set, when the helical gear B and the support shaft rotate together, the symmetrically arranged gear set can be driven to rotate through the symmetrically arranged pulley set, so as to drive the displacement member engaged therewith to move, so as to realize the automatic interval displacement of the steel plate, without manual operation, reducing labor intensity, greatly improving the automation degree and processing efficiency, and ensuring the continuous processing and processing quality of the steel plate. And no additional driving device is required for driving in this process, with low energy consumption. In addition, by applying double driving forces to the gear set, the stable operation of the displacement member can be ensured, and it is beneficial to extend the service life of the displacement member and the gear set.

[0021] 3. When the electric push rod works and extends, since the trough cylinder is slidably connected to the rotating shaft, the trough cylinder moves horizontally and is engaged with the clamping wheel, so that the trough cylinder, the clamping wheel and the rotating shaft form an integral structure. Since the linkage wheel is linked with the clamping wheel through the transmission belt, and the linkage wheel is slidably connected to the threaded cylinder, when the threaded cylinder drives the limiting plate A to move horizontally closer to and away from the steel plate, the threaded cylinder rotates synchronously with the rotating shaft. Since the threaded cylinder is threadedly connected to the lead screw, the lead screw pushes the limiting plate A to move horizontally relative to the movable plate, so that the limiting plate A can stably limit steel plates of small and large sizes, with greatly improved adaptability, and the adjustment process is simple and fast, and no additional driving device is required, with low energy consumption.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 and Figure 10, the present invention provides a technical solution: a punching and cutting device for steel structure processing, including a frame 1. At the top of the frame 1, support frames 6 are symmetrically arranged. Inside the support frames 6, hydraulic cylinders 7 are installed through. The bottom end of the hydraulic cylinder 7 is connected to a transverse movement mechanism 8. The transverse movement mechanism 8 is an electromagnetic slide rail. At the bottom end of one of the transverse movement mechanisms 8, a cutting machine 9 is arranged, and at the bottom end of the other transverse movement mechanism 8, a punching machine 10 is arranged;

[0035] Referring to Figures 1 - 8 and Figure 10 It can be known that at the front and rear ends of the frame 1, support frames 5 are symmetrically arranged. Inside the frame 1 and the support frames 5, a limit and anti-deviation mechanism 3 for horizontally clamping the steel plate is arranged through. The limit and anti-deviation mechanism 3 includes a top plate 301 welded to the support frame 6, a guide member A304 welded to the transverse movement mechanism 8, and a rotating shaft 306 connected to the support frame 5 through a bearing. At the bottom end of the top plate 301, a rotating column 302 is connected through a bearing. On the outer surface of the rotating column 302, a guide groove A303 that forms a sliding structure with the guide member A304 is opened. The guide groove A303 includes a spiral groove and a straight groove located at the bottom end of the spiral groove. Between the rotating shaft 306 and the rotating column 302, a bevel gear set 305 is connected. The bevel gear set 305 includes a driving gear connected to the rotating column 302 and a driven gear connected to the rotating shaft 306. On the outer side of the rotating shaft 306, symmetrically arranged movable plates 309 are slidably connected. At one end where the two movable plates 309 are close to each other, a limit plate A310 is arranged. On the outer surface of the rotating shaft 306, a guide groove B311 is opened. On the inner surface of the movable plate 309, a guide member B312 that forms a sliding structure with the guide groove B311 is arranged. The guide groove B311 includes an arc groove and annular grooves located at both ends of the arc groove. At the top of the support frame 5, a vertical plate 307 sleeved on the outer side of the rotating shaft 306 is arranged. At one end of the two vertical plates 307 close to the movable plate 309, a return spring 308 is arranged;

[0036] During specific implementation, to facilitate the limitation of the steel plate, at this time, the hydraulic cylinder 7 is made to drive the transverse movement mechanism 8 and the guide member A304 to move vertically downward. During this process, since the guide member A304 and the rotating column 302 are slidably connected through the guide groove A303, the rotating column 302 rotates and drives the rotating shaft 306 to rotate through the bevel gear set 305. Since the movable plate 309 and the rotating shaft 306 are slidably connected through the guide member B312 and the guide groove B311, the movable plate 309 and the limit plate A310 move in the horizontal direction, so as to quickly and stably limit the steel plate through the limit plate A310. Compared with traditional elastic clamping, it is more stable and firm, preventing displacement deviation during the cutting and drilling processes, ensuring the quality of cutting and drilling, and no additional driving device is required for driving during this process, reducing energy consumption;

[0037] In specific implementation, since the guiding groove A303 includes a spiral groove and a straight groove at the bottom end of the spiral groove, during the initial vertical downward movement of the guiding member A304, the rotating column 302 rotates under the action of the spiral groove. When the guiding member A304 separates from the spiral groove and moves into the straight groove, the rotating column 302 stops rotating. Since the guiding groove B311 is composed of an arc groove and annular grooves at both ends thereof, when the movable plate 309 moves to a specified position and the rotating shaft 306 continues to rotate, the guiding member B312 can slide in the annular groove, so that the movable plate 309 does not hinder the continuous movement of the rotating shaft 306. Since reset springs 308 are provided at one ends of the two vertical plates 307 close to the movable plate 309, when the rotating direction of the rotating shaft 306 changes, the guiding member B312 inside the movable plate 309 can quickly move into the guiding groove B311 under the action of the reset springs 308, so as to enable the movable plate 309 to move quickly.

[0038] Refer to Figures 1 - 5 and Figure 10 As can be seen, at the top end inside the frame 1, a displacement mechanism 2 for horizontally moving the steel plate is provided. The displacement mechanism 2 includes a gear set 201 connected to the frame 1 through bearings and a support shaft 204 connected to the frame 1 and the support frame 5 through bearings. A pulley set 203 forming a transmission structure is connected between the gear set 201 and the support shaft 204. A displacement member 202 is meshed and connected to the outside of the two gear sets 201. The displacement member 202 includes a roller shaft and toothed belts symmetrically arranged at the front and rear ends of the roller shaft. A helical disk A205 is slidably connected to one end of the support shaft 204 away from the displacement member 202. One side of the helical disk A205 is meshed and connected to a helical disk B208 sleeved on the outer surface of the rotating shaft 306. A disk 207 is provided at one end of the support shaft 204 close to the pulley set 203. A telescopic spring 206 is connected between the disk 207 and the helical disk A205;

[0039] During specific implementation, to facilitate the movement of the steel plate, the hydraulic cylinder 7 is actuated to vertically lift the transverse movement mechanism 8 and the guide member A304. During this process, the rotating column 302 rotates and drives the rotating shaft 306 and the helical gear disk B208 to rotate through the bevel gear set 305. Since the helical gear disk A205 is meshed and connected with the helical gear disk B208, and the gear set 201 and the support shaft 204 are linked through the pulley set 203, when the helical gear disk B208 and the support shaft 204 rotate together, the symmetrically arranged gear set 201 can be driven to rotate through the symmetrically arranged pulley set 203, thereby driving the displacement member 202 engaged therewith to move, so as to realize the automatic interval displacement of the steel plate, without manual operation, reducing the labor intensity, greatly improving the automation degree and processing efficiency, and ensuring the continuous processing and processing quality of the steel plate. Moreover, no additional driving device is required for driving during this process, with low energy consumption. In addition, by applying a double driving force to the gear set 201, the stable operation of the displacement member 202 can be ensured, and it is beneficial to extend the service life of the displacement member 202 and the gear set 201;

[0040] During specific implementation, since the disk 207 is elastically connected with the helical gear disk A205 through the telescopic spring 206, during the process that the rotating shaft 306 rotates and drives the limiting plate A310 to limit the steel plate, the helical gear disk A205 makes a horizontal movement, that is, the helical gear disk A205 is always in a reciprocating state of contact and separation with the helical gear disk B208. At this time, the support shaft 204 is in a non-rotating state.

[0041] Refer to Figures 1 - 3 and Figures 6 - 10 As can be seen, an adjustment mechanism 4 is provided between the limiting plate A310 and the movable plate 309. The adjustment mechanism 4 includes a threaded cylinder 401 connected to the movable plate 309 through a bearing and a lead screw 402 welded to the limiting plate A310, and the lead screw 402 is in threaded connection with the threaded cylinder 401. One end of the rotating shaft 306 away from the vertical plate 307 is slidably connected with a groove cylinder 406, and an electric push rod 407 is installed between the groove cylinder 406 and the convex block on the surface of the rotating shaft 306. One end of the rotating shaft 306 close to the vertical plate 307 is slidably connected with a clamping wheel 404 that forms a clamping structure with the groove cylinder 406. A linkage wheel 403 is slidably connected to the outer surface of the threaded cylinder 401, and a transmission belt 405 is wound around the surfaces of the linkage wheel 403 and the clamping wheel 404;

[0042] During specific implementation, to facilitate the stable limiting of steel plates with small and large sizes by the limiting plate A310, the electric push rod 407 is operated to extend at this time. Since the grooved drum 406 is slidably connected to the rotating shaft 306, the grooved drum 406 moves horizontally and engages with the clamping wheel 404, so that the grooved drum 406, the clamping wheel 404 and the rotating shaft 306 form an integral structure. Since the linkage wheel 403 and the clamping wheel 404 are linked by the transmission belt 405, and the linkage wheel 403 is slidably connected to the threaded barrel 401, when the threaded barrel 401 drives the limiting plate A310 to move horizontally closer to and away from the steel plate, the threaded barrel 401 rotates synchronously with the rotating shaft 306. Since the threaded barrel 401 is threadedly connected to the lead screw 402, the lead screw 402 pushes the limiting plate A310 to move horizontally relative to the movable plate 309, so that the limiting plate A310 can stably limit steel plates with small and large sizes, greatly improving the adaptability, and the adjustment process is simple and fast. Moreover, no additional driving device is required, and the energy consumption is low.

[0043] Refer to Figure 2 、 Figure 6 、 Figure 7 and Figure 9 It can be known that a guiding telescopic rod 409 is connected between the limiting plate A310 and the movable plate 309, and the guiding telescopic rods 409 are symmetrically arranged on both sides of the threaded barrel 401. A limiting plate B408 sleeved on the outer sides of the threaded barrel 401 and the guiding telescopic rod 409 is arranged on one side of the support frame 6 close to the threaded barrel 401, and a ball is rotatably connected to one end of the limiting plate B408 close to the linkage wheel 403;

[0044] During specific implementation, through the cooperation of the limiting plate B408 and the ball, the limiting of the linkage wheel 403 can be realized, so that it can only perform rotational movement, thereby preventing it from moving horizontally together with the threaded barrel 401. The guiding telescopic rod 409 can play a role in limiting the limiting plate A310, so that the limiting plate A310 only moves in the horizontal direction, thereby preventing it from rotating together with the threaded barrel 401 and improving the stability.

[0045] Working principle: When using the punching and cutting device for steel structure processing, place the steel plate on the top of the displacement member 202 and make one end of it pass through the support frame 6. At this time, start the hydraulic cylinder 7, so that the hydraulic cylinder 7 drives the transverse movement mechanism 8, the cutting machine 9, the punching machine 10 and the guide member A304 to move vertically downward to the designated position together. During this process, through the sliding action between the guide member A304 and the rotating column 302, the rotating column 302 rotates and drives the rotating shaft 306 to rotate through the bevel gear set 305. Through the sliding action between the movable plate 309 and the rotating shaft 306, the movable plate 309 and the limiting plate A310 move horizontally until the limiting plate A310 contacts the steel plate and realizes stable limiting. Then, according to the actual processing requirements, make the hydraulic cylinder 7 continue to control the cutting machine 9 or the punching machine 10 to continue to move downward for cutting or drilling operations. After a single cutting or drilling operation is completed, the hydraulic cylinder 7 controls the cutting machine 9 and the punching machine 10 to move upward and reset synchronously. During this process, the rotating column 302 rotates in the reverse direction and drives the rotating shaft 306 and the helical gear disk B208 to rotate, so that the limiting of the steel plate by the limiting plate A310 can be quickly released. At the same time, through the meshing action between the helical gear disk A205 and the helical gear disk B208 and the linkage action between the gear set 201 and the support shaft 204, when the helical gear disk B208 and the support shaft 204 rotate together, the symmetrically arranged gear set 201 can be driven to rotate through the symmetrically arranged pulley sets 203, thereby driving the displacement member 202 engaged with it to move, so as to realize the automatic interval displacement of the steel plate. In this way, the cutting and drilling operations of the steel plate can be completed by repeating this process;
