Description
Technical Field
[0001] This utility model belongs to the field of steel plate punching and shearing technology, specifically a steel plate punching and shearing device. Background Technology
[0002] A punching and shearing machine is a machine tool that integrates multiple functions such as metal shearing, punching, plate shearing, and bending. It has the advantages of easy operation, low energy consumption, and low maintenance costs, making it the preferred equipment for metal processing in modern manufacturing industries (such as metallurgy, bridges, communications, power, and military industries).
[0003] Existing steel plate punching and shearing machines are high-pressure punching and shearing machines. The steel plate to be cut is placed under the punching head through a positioning mechanism, and the hydraulic mechanism is activated to move the punching head downward to complete the punching and shearing of the steel plate at a predetermined position. During punching and shearing, it is very easy for debris to splatter. In existing punching and shearing devices with protective baffles, the protective baffle is often connected to the bottom of the punching head. Through elastic connections, its lower end is always in contact with the surface of the steel plate during punching and shearing. This increases the resistance of the punching head when it moves downward to punch and shear the steel plate, thus increasing the energy consumption of the punching head. Therefore, it is necessary to develop a new type of steel plate punching and shearing device to overcome the shortcomings of the existing technology. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a steel plate punching and shearing device, which has the advantages of good protection and low energy consumption.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel plate punching and shearing device, comprising a main unit, a hydraulic mechanism integrally arranged above the main unit, a positioning platform located directly below the hydraulic mechanism on the top of the main unit, a lifting seat located directly above the positioning platform connected to the bottom of the hydraulic mechanism, an installation head fixedly connected to the bottom of the movable end of the lifting seat, a punching and shearing head installed at the bottom of the installation head, a plurality of evenly distributed protective components connected to the outer surface of the installation head, a protective cover plate fixedly connected to the outer surface of the installation head, and the protective cover plate and the plurality of protective components covering the punching and shearing head around and on top;
[0006] The lower extension lines of several of the protective components are located outside the positioning table. When the bottom of the punching and shearing head contacts the top of the positioning table, the horizontal plane where the bottom of the protective component is located is between the horizontal planes where the top and bottom of the positioning table are located.
[0007] Preferably, the protective component includes an adapter frame fixedly connected to the lower side of the mounting head, and a safety component hinged to the other end of the adapter frame. A first guard plate is fixedly connected to the bottom of the safety component. The lower end of the first guard plate moves down synchronously with the punching and shearing head and eventually lies between the top and bottom horizontal planes of the positioning table.
[0008] Preferably, a second guard plate is provided on the outer surface of the first guard plate near the punching and shearing head, and a plurality of evenly distributed buffer springs are fixedly connected between the second guard plate and the first guard plate.
[0009] Preferably, the safety component includes a connecting sleeve fixedly connected to the top of the first guard plate, and the connecting sleeve is movably connected to the bottom of the adapter frame at the end away from the mounting head.
[0010] Preferably, a coaxial positioning shaft is inserted inside the connecting sleeve, the inner diameter of the connecting sleeve is larger than the outer diameter of the positioning shaft, and a positioning locking element is provided between the connecting sleeve and the positioning shaft.
[0011] Preferably, the positioning locking component includes two first positioning rings and a second positioning ring, which are sleeved between the connecting sleeve and the positioning shaft. The cross-section of the first positioning ring and the second positioning ring is "L" shaped. The second positioning ring and the first positioning ring are engaged with each other, and a gap is left between the first positioning ring and the second positioning ring.
[0012] The first positioning ring is fixedly sleeved on the outer surface of the positioning shaft, and a gap is left between it and the inner wall of the connecting sleeve. The second positioning ring is fixedly sleeved on the inner wall of the connecting sleeve, and a gap is left between it and the outer surface of the positioning shaft.

[0014] Preferably, the release groove is a cylindrical structure and the slot is a spherical structure. The inner diameter of the release groove and the slot is the same and is adapted to the outer diameter of the locking ball. When the top of the locking ball is attached to the inside of the slot, its lower end is still located inside the release groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. Due to the setting of the protective components, the present invention can completely block the splashes from all sides with the cooperation of several protective components around the punching and shearing head. The protective cover can prevent upward splashes, and the splashes can be buffered by any protective component after they hit the sideways, so as to offset the speed and force of the splashes, effectively achieving the effect of preventing splashes. At the same time, it will not cause the protective components to be subjected to excessive impact, thus reducing the protection life.

With the cooperation of the release groove, the locking ball locks the second positioning ring and the first positioning ring, thereby stopping the first guard plate from swinging outward. This allows the strong impact to be compressed by the second guard plate to buffer the spring, effectively reducing excessive splashing. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 7As shown, this utility model provides a steel plate punching and shearing device, including a main unit 1, a hydraulic mechanism 2 integrally arranged on the top of the main unit 1, a positioning platform 3 located directly below the hydraulic mechanism 2 on the top of the main unit 1, a lifting seat 4 located directly above the positioning platform 3 connected to the bottom of the hydraulic mechanism 2, an installation head 5 fixedly connected to the bottom of the movable end of the lifting seat 4, a punching and shearing head 8 installed at the bottom of the installation head 5, a plurality of evenly distributed protective components 6 connected to the outer surface of the installation head 5, a protective cover plate 7 fixedly connected to the outer surface of the installation head 5, and the protective cover plate 7 and the plurality of protective components 6 covering the punching and shearing head 8 around and on top.
[0028] The lower extension lines of several protective components 6 are located outside the positioning table 3. When the bottom of the punching and shearing head 8 contacts the top of the positioning table 3, the horizontal plane where the bottom of the protective component 6 is located is between the horizontal planes where the top and bottom of the positioning table 3 are located. Due to the setting of the protective components 6, with the cooperation of several protective components 6 around the punching and shearing head 8, it can completely block the splashes from all sides. The protective cover plate 7 can prevent upward splashes. At the same time, after the splashes hit any of the protective components 6 laterally, they can be buffered by the protective components to offset the splash speed and force, effectively achieving the effect of preventing splashes. At the same time, it will not cause the protective components to be subjected to excessive impact, thus reducing the protection life.
[0029] The protective component 6 includes an adapter 61 fixedly connected to the lower side of the mounting head 5. The other end of the adapter 61 is hinged to a safety component 62. The bottom of the safety component 62 is fixedly connected to a first guard plate 63. The lower end of the first guard plate 63 moves down synchronously with the punching and shearing head 8 and is eventually located between the top and bottom horizontal planes of the positioning table 3.
[0030] Among them, a second guard plate 64 is provided on the outer surface of the first guard plate 63 near the punching and shearing head 8. A number of evenly distributed buffer springs 65 are fixedly connected between the second guard plate 64 and the first guard plate 63. Due to the setting of the buffer springs 65, the elastic recovery performance of the first guard plate 63 and the second guard plate 64 can achieve a good buffering and protection effect, thereby greatly reducing the safety hazards caused by splashing to the staff.
[0031] The safety component 62 includes a connecting sleeve 621 fixedly connected to the top of the first guard plate 63, and the connecting sleeve 621 is movably connected to the bottom of the adapter 61 at the end away from the mounting head 5.
[0032] The connecting sleeve 621 has a coaxial positioning shaft 622 inside it. The inner diameter of the connecting sleeve 621 is larger than the outer diameter of the positioning shaft 622. A positioning locking element is provided between the connecting sleeve 621 and the positioning shaft 622.
[0033] The positioning locking component includes two first positioning rings 623 and a second positioning ring 624 that are sleeved between the connecting sleeve 621 and the positioning shaft 622. The cross-section of the first positioning ring 623 and the second positioning ring 624 is "L" shaped. The second positioning ring 624 and the first positioning ring 623 are interlocked, and a gap is left between the first positioning ring 623 and the second positioning ring 624.
[0034] The first positioning ring 623 is fixedly sleeved on the outer surface of the positioning shaft 622, with a gap between it and the inner wall of the connecting sleeve 621. The second positioning ring 624 is fixedly sleeved on the inner wall of the connecting sleeve 621, with a gap between it and the outer surface of the positioning shaft 622. Due to the arrangement of the first positioning ring 623 and the second positioning ring 624, the connecting sleeve 621 and the positioning shaft 622 can rotate stably relative to each other, and the axial relative movement between the two can be avoided, thereby ensuring the stable swing of the first guard plate 63 and achieving a stable protective effect.
[0035] The second positioning ring 624 and the first positioning ring 623 are provided with a locking member at the interlocking point. The locking member includes a release groove 625 opened inside the second positioning ring 624 and a locking groove 626 opened inside the first positioning ring 623 and located directly above the release groove 625. A locking ball 627 is movably installed inside the release groove 625.
[0036] The release groove 625 is cylindrical, and the locking groove 626 is spherical. The inner diameters of the release groove 625 and the locking groove 626 are the same and are compatible with the outer diameter of the locking ball 627. When the top of the locking ball 627 is attached to the inside of the locking groove 626, its lower end is still located inside the release groove 625. Due to the setting of the locking groove 626, when the second positioning ring 624 moves rapidly with the first guard plate 63, it can obtain sufficient centrifugal force and lock into the locking groove 626. With the cooperation of the release groove 625, the locking ball 627 locks the second positioning ring 624 and the first positioning ring 623, thereby stopping the first guard plate 63 from swinging outward. This allows the strong impact to compress the buffer spring 65 through the second guard plate 64, effectively reducing excessive splashing.
[0037] Working principle and usage process of this utility model:
[0038] First, replace the required punching head 8 according to the punching and shearing needs. Then, place the parts to be punched and sheared on the positioning table 3. After starting the equipment, under the control of the host machine 1, the lifting seat 4 is moved by the hydraulic mechanism 2. The installation head 5 can push the protective component 6, the protective cover plate 7 and the punching and shearing head 8 to move down slowly and synchronously. Then, the punching and shearing of the parts below is completed by the punching and shearing head 8. During this period, the protective cover plate 7 prevents the punching and shearing debris from splashing upwards, while the protective component 6 prevents the punching and shearing debris from splashing laterally.
[0039] When shearing debris is thrown laterally, it first impacts the second guard plate 64 and is blocked by the first guard plate 63, which compresses the buffer spring 65 to increase its elastic restoring force. At the same time, the lower end of the first guard plate 63 swings outward around the safety component 62 at its upper end, thereby consuming the splashing force and achieving the protection against excessive splashing range that could injure workers.
[0040] When the splashing speed and impact force are too high, the first guard plate 63 will swing outward rapidly, and through the connecting sleeve 621, it will drive the second positioning ring 624 to rotate rapidly between the positioning shaft 622 and the first positioning ring 623. Then, under the drive of the release groove 625, the locking ball 627 will rotate rapidly around the positioning shaft 622 and obtain sufficient centrifugal force, so that its outer end is locked into the locking groove 626, while the inner end remains in the release groove 625. This locks the first positioning ring 623 and the second positioning ring 624, preventing the second positioning ring 624, the connecting sleeve 621, and the first guard plate 63 from swinging outward. This strongly blocks the splashed debris and allows it to continue to pass through the second guard plate 64 to compress the buffer spring 65.
