Description

Technical Field

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

[0002] Steel components refer to composite steel structure components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected by connectors. Steel components have the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. They are widely used in industries such as building construction and railway construction. At present, in the production process of steel plates, in order to meet the splicing requirements, they must be punched and cut. Generally, punching and cutting devices are used to cut steel plates into steel structures of certain specifications, and holes are punched at designated positions of the steel structures according to needs, and then they are applied to various aspects of construction.

[0003] According to the announcement number CN215091958U, a punching and cutting device for steel structure processing includes a working platform, the surface of the working platform is provided with a concave track, and the interior of the concave track is provided with a slider; a placement plate, which is fixedly installed above the slider, and a spring is placed inside the placement plate, and a side plate is provided on one side of the spring; a steel plate is fixedly installed on the surface of the placement plate, and the use of the concave track and the slider facilitates the transportation of the steel plate, and the steel plate is moved by the movement of the slider. The use of the concave track limits the moving position of the steel plate to avoid punching errors caused by deflection during transportation. The use of the side plate and the spring has a certain elastic activity space, which is convenient for the placement of steel plates of different specifications. At the same time, the steel plate is clamped and fixed to avoid shaking during punching and cutting due to loose positioning, which affects the punching and cutting quality.

[0004] With regard to the above-mentioned related schemes, the steel plate is clamped by the cooperation of the placement plate, side plate and spring, and the steel plate is cut and drilled by the cutting bar and punch. After completing a single processing, the operator needs to manually control the slider to push the steel plate along the concave track for subsequent operations. However, in this process, the elastic clamping relies on the spring deformation to generate the clamping force, which is prone to attenuation under the vibration impact of processing, resulting in displacement of the steel plate, seriously affecting the positioning accuracy of cutting and drilling, and the manually intervened slider pushing mechanism not only increases the labor intensity, but also reduces the collaborative efficiency of the production line due to inconsistent operation rhythm, and the equipment needs to be frequently started and stopped in the clamping-processing-pushing process, which greatly shortens the actual effective processing time. The above problems lead to a low degree of automation of the punching and cutting device, which cannot achieve continuous processing of the steel plate, affects the processing efficiency of the steel plate, and makes it difficult to ensure product quality.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention comprehensively optimizes the precision, efficiency and adaptability of steel plate processing through the synergistic effect of the limit anti-deviation mechanism, the displacement mechanism and the adjustment mechanism. The limit anti-deviation mechanism utilizes the sliding connection between the guide part A and the rotating column and the bevel gear group transmission to make the limit plate A move horizontally under the drive of the hydraulic cylinder to achieve rapid clamping of the steel plate. The clamping stability is greatly improved compared with the traditional spring clamping, and the cutting / drilling accuracy is significantly guaranteed; the displacement mechanism automatically completes the interval pushing of the steel plate in the return stroke of the hydraulic cylinder through the engagement of the helical gear disc, the linkage of the pulley group and the symmetrical drive design, which greatly improves the efficiency compared with manual operation. At the same time, the dual driving force input ensures the smooth operation of the displacement part and extends the life of the components; the adjustment mechanism realizes the adaptive adjustment of the spacing of the limit plate A through the grooved barrel-clamping wheel engagement and the threaded barrel-screw transmission to adapt to steel plates of different sizes. The three mechanisms are integrated and linked, which reduces manual intervention and improves the degree of automation while taking into account the optimization of processing continuity, and the comprehensive processing efficiency is greatly improved. Moreover, the entire process is driven by the same hydraulic system and does not require an independent power source.

[0019] 1. The punching and cutting device for steel structure processing, 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, and 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 limit plate A move horizontally, so that the steel plate can be quickly and stably limited by the limit plate A. Compared with traditional elastic clamping, it is more stable and firm, preventing displacement and offset during cutting and drilling, ensuring the quality of cutting and drilling, and no additional driving device is required for driving in this process, reducing energy consumption.

[0020] 2. The punching and cutting device for steel structure processing, 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 bevel gear set to rotate through the bevel gear set. Since the bevel gear set A is meshed and connected with the bevel gear set B, and the gear set and the support shaft are linked by the pulley set, when the bevel gear set B and the support shaft rotate together, the symmetrically arranged gear set can be driven to rotate by the symmetrically arranged pulley set, thereby driving the displacement member meshed with it to move, so as to realize automatic interval displacement of the steel plate, without manual operation, reducing labor intensity, greatly improving the degree of automation 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, so the energy consumption is low.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1 and Figure 10The present invention provides a technical solution: a punching and cutting device for steel structure processing, comprising a frame 1, a support frame 6 symmetrically arranged on the top of the frame 1, a hydraulic cylinder 7 installed through the interior of the support frame 6, the bottom end of the hydraulic cylinder 7 is connected to a transverse mechanism 8, the transverse mechanism 8 uses an electromagnetic slide rail, a cutting machine 9 is arranged at the bottom end of one of the transverse mechanisms 8, and a punching machine 10 is arranged at the bottom end of the other transverse mechanism 8;

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

[0036] During specific implementation, in order to facilitate the limiting of the steel plate, the hydraulic cylinder 7 drives the transverse movement mechanism 8 and the guide member A304 to move vertically downward. During this process, since the guide member A304 is slidably connected to the rotating column 302 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 is slidably connected to the rotating shaft 306 through the guide member B312 and the guide groove B311, the movable plate 309 and the limiting plate A310 move horizontally, so that the steel plate can be quickly and stably limited by the limiting plate A310. Compared with traditional elastic clamping, it is more stable and firm, preventing displacement and offset during cutting and drilling, ensuring the quality of cutting and drilling, and no additional driving device is required to drive the process, reducing energy consumption.

[0037] During specific implementation, since the guide groove A303 includes a spiral groove and a straight groove located at the bottom end of the spiral groove, during the initial vertical downward movement of the guide member A304, the rotating column 302 is rotated by the action of the spiral groove, and when the guide member A304 separates from the spiral groove and moves into the straight groove, the rotating column 302 stops rotating; since the guide groove B311 is composed of an arc groove and annular grooves located at both ends, when the movable plate 309 moves to the specified position and the rotating shaft 306 continues to rotate, the guide member B312 can slide in the annular groove, so that the movable plate 309 will not hinder the continued movement of the rotating shaft 306, and since the two vertical plates 307 are both provided with a return spring 308 at one end close to the movable plate 309, when the rotating shaft 306 changes its rotation direction, the guide member B312 on the inner side of the movable plate 309 can be quickly moved into the guide groove B311 under the action of the return spring 308, so that the movable plate 309 can move quickly.

[0038] See Figure 1-Figure 5 and Figure 10 It can be seen that a displacement mechanism 2 for laterally moving the steel plate is provided at the top of the inner side of the frame 1, and the displacement mechanism 2 includes a gear set 201 connected to the frame 1 through a bearing and a support shaft 204 connected to the frame 1 and the support frame 5 through a bearing, a pulley set 203 constituting a transmission structure is connected between the gear set 201 and the support shaft 204, and a displacement member 202 is meshedly connected on the outer sides of the two gear sets 201, and the displacement member 202 includes a roller and a toothed belt symmetrically arranged at the front and rear ends of the roller, and the end of the support shaft 204 away from the displacement member 202 is slidably connected to a bevel gear disk A205, and one side of the bevel gear disk A205 is meshedly connected to a bevel gear disk B208 sleeved on the outer surface of the rotating shaft 306, and a disc 207 is provided on the end of the support shaft 204 close to the pulley set 203, and a telescopic spring 206 is connected between the disc 207 and the bevel gear disk A205;

[0039] In the specific implementation, in order to facilitate the movement of the position of the steel plate, the hydraulic cylinder 7 drives the transverse movement mechanism 8 and the guide member A304 to move vertically upward. In this process, the rotating column 302 rotates and drives the rotating shaft 306 and the bevel gear set 305 to rotate. Since the bevel gear set A205 is meshed with the bevel gear set B208, and the gear set 201 and the support shaft 204 are linked by the pulley set 203, when the bevel gear set B208 and the support shaft 204 rotate together, the symmetrically arranged pulley set 203 can be used to drive the symmetrically arranged pulley set 203 to rotate. The gear set 201 is rotated, thereby driving the displacement member 202 meshing therewith to move, so as to realize automatic interval displacement of the steel plate. No manual operation is required, which reduces labor intensity, greatly improves the degree of automation and processing efficiency, and can ensure the continuous processing and processing quality of the steel plate. In addition, no additional driving device is required in this process, and energy consumption is low. In addition, by applying a dual driving force to the gear set 201, the stable operation of the displacement member 202 can be ensured, and the service life of the displacement member 202 and the gear set 201 can be extended.

[0040] During specific implementation, since the disc 207 and the bevel gear disc A205 are elastically connected through the telescopic spring 206, when the rotating shaft 306 rotates and drives the limiting plate A310 to limit the steel plate, the bevel gear disc A205 moves horizontally, that is, the bevel gear disc A205 is always in a reciprocating state of contact and separation with the bevel gear disc B208, and the support shaft 204 is in a non-rotating state.

[0041] See Figure 1-Figure 3 and Figures 6-10 It can be seen that an adjustment mechanism 4 is provided between the limit plate A310 and the movable plate 309, and the adjustment mechanism 4 includes a threaded cylinder 401 connected to the movable plate 309 through a bearing and a screw rod 402 welded to the limit plate A310, and the screw rod 402 is threadedly connected to the threaded cylinder 401, and the end of the rotating shaft 306 away from the vertical plate 307 is slidably connected to the grooved cylinder 406, and an electric push rod 407 is installed between the grooved cylinder 406 and the protrusion on the surface of the rotating shaft 306, and the end of the rotating shaft 306 close to the vertical plate 307 is slidably connected to the card wheel 404 forming a snap-fit ​​structure with the grooved cylinder 406, and the outer surface of the threaded cylinder 401 is slidably connected to the linkage wheel 403, and a transmission belt 405 is wound around the surface of the linkage wheel 403 and the card wheel 404;

[0042] In the specific implementation, in order to facilitate the limit plate A310 to stably limit the small and large-sized steel plates, the electric push rod 407 is operated and extended. Since the groove drum 406 is slidably connected to the rotating shaft 306, the groove drum 406 moves horizontally and engages with the card wheel 404, so that the groove drum 406, the card wheel 404 and the rotating shaft 306 form an integrated structure. Since the linkage wheel 403 and the card wheel 404 are linked by the transmission belt 405, and the linkage wheel 403 is slidably connected to the threaded cylinder 401, the threaded cylinder 401 is screwed. When the threaded cylinder 401 drives the limit plate A310 to move horizontally toward or away from the steel plate, the threaded cylinder 401 rotates synchronously with the rotating shaft 306. Since the threaded cylinder 401 is threadedly connected to the screw rod 402, the screw rod 402 pushes the limit plate A310 to move horizontally relative to the movable plate 309, so that the limit plate A310 can stably limit small and large-sized steel plates, the adaptability is greatly improved, the adjustment process is simple and quick, and no additional driving device is required, and the energy consumption is low.

[0043] See Figure 2 、 Figure 6 、 Figure 7 and Figure 9 It can be seen that a guide telescopic rod 409 is connected between the limit plate A310 and the movable plate 309, and the guide telescopic rod 409 is symmetrically arranged on both sides of the threaded cylinder 401. The support frame 6 is provided with a limit plate B408 on the side of the threaded cylinder 401, which is sleeved on the outside of the threaded cylinder 401 and the guide telescopic rod 409, and a ball is rollingly connected to the end of the limit plate B408 close to the linkage wheel 403;

[0044] In specific implementation, the cooperation between the limit plate B408 and the ball can achieve the limitation of the linkage wheel 403, so that it can only perform rotational movement, thereby preventing it from moving laterally with the threaded barrel 401. The guide telescopic rod 409 can limit the limit plate A310, so that the limit plate A310 can only move in the horizontal direction, thereby preventing it from rotating with the threaded barrel 401, thereby improving stability.

[0045] Working principle: When using the punching and cutting device for steel structure processing, the steel plate is placed on the top of the displacement member 202, and one end of the displacement member passes through the support frame 6. At this time, the hydraulic cylinder 7 is started, so that the hydraulic cylinder 7 drives the transverse mechanism 8, the cutting machine 9, the punching machine 10 and the guide member A304 to move vertically downward to the specified position. In this process, the sliding action of the guide member A304 and the rotating column 302 causes the rotating column 302 to rotate and drives the rotating shaft 306 to rotate through the bevel gear set 305. The sliding action of the movable plate 309 and the rotating shaft 306 causes the movable plate 309 and the limit plate A310 to move horizontally until the limit plate A310 contacts the steel plate and achieves stable limit. Then, according to actual processing requirements, the hydraulic cylinder 7 continues to control the cutting machine 9 or the punching machine 10 to continue to move downward so that Perform 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 up and reset synchronously. During this process, the rotating column 302 rotates in the opposite direction and drives the rotating shaft 306 and the bevel gear set B208 to rotate through the bevel gear set 305, so that the limit of the limit plate A310 on the steel plate can be quickly released. At the same time, through the meshing action of the bevel gear set A205 and the bevel gear set B208 and the linkage action of the gear set 201 and the support shaft 204, when the bevel gear set B208 and the support shaft 204 rotate together, the symmetrically arranged pulley set 203 can drive the symmetrically arranged gear set 201 to rotate, thereby driving the displacement member 202 meshed therewith to move, so as to realize automatic interval displacement of the steel plate. In this reciprocating manner, the cutting and drilling operations of the steel plate can be completed.
