Description

Technical Field

[0001] This utility model belongs to the technical field of shearing equipment, specifically a shearing equipment for steel structure production. Background Technology

[0002] Shearing equipment is a type of mechanical equipment used for cutting and processing sheet metal. Its working principle is to apply shearing force to the sheet metal by utilizing the relative movement between the upper and lower blades, so that the sheet metal breaks and separates according to the required size and shape.

[0003] In the modern steel structure manufacturing industry, because steel structure plates are generally thick and heavy, after being sheared by shearing equipment, the sheared plates usually lack stable and reliable support and guiding devices for support and unloading. The steel structure plates will fall freely from the workbench into the material collection box. The plates in the collection box cannot be neatly arranged, which greatly reduces the utilization rate of the collection box space and increases the subsequent manual sorting time, affecting work efficiency. On the other hand, during the free fall process, the plates will collide strongly with scattered plates, and the surface of the plates is very prone to significant damage, seriously affecting the quality of the sheared plates. Utility Model Content

[0004] To address the problem that traditional shearing equipment lacks a stable and reliable support and guiding device to support and guide the sheet metal during cutting, which greatly reduces the utilization rate of the material holding box, lowers work efficiency, and causes significant damage to the sheet metal, this utility model provides a shearing equipment for steel structure production.

[0005] This utility model is achieved through the following technical solution:

[0006] A shearing machine for steel structure production includes a frame, an upper blade holder that can be raised and lowered and mounted on the frame, and a lower blade holder that is mounted on the frame via a lower blade holder. A support frame is connected to the bottom of the frame on the unloading side. A support seat is vertically slidably connected to the upper part of the support frame, and a support spring is provided on the support frame to elastically support the support seat upward. A support column is rotatably connected to the support seat via a left-right rotating shaft. The support column has a guide groove that runs through the left and right sides. The guide groove includes a vertical section at the bottom and an inclined section at the top that bends in the feeding direction. A sliding shaft that slides and guides the guide groove is fixedly connected to the support frame via a sliding shaft support frame. A support plate that can support the sheared sheet is connected to the top of the support column. An inclined guide groove that can receive the sheet on the support plate is connected to the support frame.

[0007] A further improvement of this utility model is that the inclined section is an arc shape that bulges backward.

[0008] A further improvement of this utility model is that an electromagnet capable of attracting the material is provided between the support column and the material support plate.

[0009] A further improvement of this utility model is that a tension spring mounting bracket is connected to the support base, and a tension spring capable of pulling the support column forward is connected to the tension spring mounting bracket.

[0010] A further improvement of this utility model is that a limiting groove for positioning and installing the support spring is provided in the middle of the lower end of the support base.

[0011] A further improvement of this utility model is that the bottom of the support base is fixedly connected with several guide rods that are vertically slidably inserted into the support frame, and the lower end of the guide rods is screwed with a nut.

[0012] A further improvement of this utility model is that four guide rods are provided, and they are arranged in a ring array relative to the supporting springs.

[0013] A further improvement of this utility model is that two guide pillars are installed on the frame and slide vertically with the upper tool post, and a limiting cylinder that can limit the descent of the upper tool post is fitted on the guide pillars.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0015] In operation, the feeding mechanism feeds material backward, the support seat is supported upward by the support spring, the sliding shaft is located at the bottom of the vertical section of the guide groove, and the material support plate is located below the plate to be cut. The hydraulic cylinder extends, driving the lower blade holder and upper blade downward. The shearing force of the upper and lower blades cuts the steel plate. During the shearing process, the cut steel plate falls onto the material support plate. Under the weight of the steel plate, the support seat compresses downward against the support spring, and simultaneously the guide groove and sliding shaft slide downward in a guiding engagement. When the sliding shaft is located within the inclined section of the guide groove, the support column rotates along the guide. The shaft rotates backward until it reaches the top of the inclined section of the guide groove. At this point, the steel plate on the support plate slides obliquely onto the guide groove. The support base, support column, and support plate are reset under the elastic support of the support spring and the sliding guidance of the shaft and guide groove. The steel plate slides obliquely backward along the guide groove and falls smoothly into the appropriately shaped collection box, ensuring the neatness, reliability, and safety of the material falling. This effectively ensures the space utilization of the collection box, improves work efficiency, and greatly reduces collision damage between plates, thus improving shearing quality. The overall structure is simple, easy to use, and highly practical. Attached Figure Description

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1-4As shown, this utility model discloses a shearing equipment for steel structure production, including a frame 1 with a U-shaped frame structure and a feeding device. An upper blade holder 2 is vertically slidably installed inside the frame 1. A vertical hydraulic cylinder 3 is installed on the upper part of the upper beam of the frame 1, and the telescopic end (lower end) of the hydraulic cylinder 3 is connected to the upper blade holder 2. An upper blade 4 is installed at the bottom front side of the upper blade holder 2, and a lower blade 8 is installed on the frame 1 (bottom) via a lower blade holder 7 (the lower blade 8 is installed on the upper rear side of the lower blade holder 7, and the lower blade 8 and the upper blade 4 have a small shearing gap in the vertical direction). The feeding device includes a support frame 9 connected to the bottom of the feeding side (rear side) of the frame 1. A support seat 12 is vertically slidably connected to the upper part of the support frame 9, and the support frame 9 is provided with an upward elastic support for the support seat 12. Support spring 18; The upper end of support base 12 has an upward and backward opening mounting groove. Support column 13 is rotatably connected and installed in the mounting groove through a left-right rotating shaft 16. Support column 13 has a left-right through guide groove 14. Guide groove 14 includes a vertical section at the bottom and an inclined section connected to the upper part of the vertical section and bent in the feeding direction (forward). Support frame 9 is fixedly connected to sliding shaft 20 that slides and guides guide groove 14 through sliding shaft support frame 19. Support column 13 is connected to a material support plate 11 that can support the sheared plate. Support frame 9 is also connected to a guide groove 10 that can support the plate on the material support plate 11 with an inclined setting (inclined downward in the front-to-back direction). The bottom end of guide groove 10 is provided with a material holding box. The space of the material holding box is adapted to the shape of the sheared plate.

[0024] In use, the feeding mechanism at the front of the shearing equipment feeds the plate backward (supported on the upper part of the lower blade 8). The plate is positioned by the back gauge device at the rear of the shearing equipment, and the plate is pressed by the pressure cylinder at the front of the shearing equipment to prevent displacement during shearing. The support seat 12 is supported upward by the support spring 18. The sliding shaft 20 is located at the bottom of the vertical section of the guide groove 14, and the support plate 11 is located below the plate to be cut (with a small gap, such as 2-5mm). The hydraulic cylinder 3 extends, driving the lower blade holder 7 and the upper blade 4 to move downward. The shearing force of the upper blade 4 and the lower blade 8 shears the steel plate. During the shearing process, the cut steel plate falls onto the support plate 11. Under the weight of the steel plate (steel plates used in traditional steel structure production are relatively heavy), the support seat 12 compresses and moves downward against the support spring 18, while the guide groove... The sliding guide 14 moves downward in coordination with the sliding shaft 20. When the sliding shaft 20 is located in the inclined section of the guide groove 14, the support column 13 (material support plate 11) flips backward along the rotating shaft 16 until the sliding shaft 20 is at the uppermost end of the inclined section of the guide groove 14. At this time, the steel plate on the material support plate 11 slides down onto the guide groove 10 (the upper end of the guide groove 10 is connected to the material support plate 11). The support seat 12, support column 13, and material support plate 11 are reset under the elastic support of the support spring 18 and the sliding guide coordination between the sliding shaft 20 and the guide groove 14. The steel plate slides backward along the guide groove 10 and falls smoothly into the matching material box, ensuring the neatness, reliability, and safety of the material falling, effectively ensuring the space utilization of the material box, improving work efficiency, and greatly reducing the collision damage between plates, thus improving the shearing quality. The overall structure is simple, easy to use, and practical.

[0025] Furthermore, the inclination angle of the guide chute 10 can be set to 30 degrees, and its end (lower or rear end) has an arc-shaped section transitioning to the horizontal direction, effectively reducing the falling speed of the steel plate, avoiding a large impact on the material container, and ensuring that it falls smoothly and accurately into the material container. The wall of the material container can be equipped with a rubber protective layer to buffer the collision between the steel plate and the wall of the material container.

[0026] Furthermore, the guide chute 10 has upward-facing guards on both sides to effectively guide and limit the sheared steel plates, ensuring the accuracy of the steel plates sliding downwards.

[0027] Furthermore, to ensure that the steel plate can accurately fall into the appropriately sized guide trough 10, the upper end of the retaining edge is bent outwards, which plays a transitional guiding role for the steel plate.

[0028] On the other hand, a stop plate can be provided at the end of the guide chute 10 to limit the stop position of the steel plate end, and the steel plate can be accurately gripped, transferred and stored by a robot (electromagnetic suction).

[0029] Two guide posts 5 are installed on the left and right sides of the frame 1, which slide vertically and guide the upper tool holder 2. A limiting cylinder 6 is installed on the guide post 5 to limit the downward movement of the upper tool holder 2. The guide posts 5 guide the upper tool holder 2 vertically, ensuring the stability and accuracy of the operation of the upper tool holder 2 (upper blade 4). The limiting cylinder 6 limits the downward movement of the upper tool holder 2 to its extreme position, ensuring that the upper tool holder 2 can effectively shear the steel plate within a small stroke, and avoiding interference with other components, thus ensuring good safety.

[0030] The inclined section is an arc shape that bulges backward. The inclined section is tangent to the vertical section, forming a smooth transition and ensuring the stability and smoothness of the movement of each component.

[0031] An electromagnet 21 is installed between the support column 13 and the material support plate 11 to attract the steel plate. During the shearing operation, the electromagnet 21 is energized, reliably attracting the sheared steel plate (middle part) (the material support plate 11 is made of non-magnetic material). After the support column 13 (electromagnet 21, material support plate 11) flips back into place, the electromagnet 21 is de-energized, and the steel plate tilts and slides onto the guide chute 10. This ensures the reliability and stability of the steel plate falling.

[0032] Furthermore, power-off and power-off switches for the electromagnet 21 can be provided at the upper and lower ends of the guide groove 14, which are triggered by the sliding shaft 20 to ensure the reliability of the electromagnet 21's operation.

[0033] The support base 12 is equipped with a tension spring mounting bracket 22, and a tension spring 15 is connected to the tension spring mounting bracket 22 to pull the support column 13 forward. The tension spring 15 enables the support column 13 to quickly reset (into an upright state) after being flipped (after the steel plate falls), avoiding jamming and ensuring smooth operation.

[0034] The support base 12 has a limiting groove at its lower center for positioning and installing the support spring 18. The limiting groove fits into the support spring 18, ensuring the stability of the support spring 18 in supporting the support base 12 and preventing the support spring 18 from shifting during the extension and retraction process.

[0035] The support base 12 has several guide rods 17 fixedly connected to its bottom, which are vertically slidably inserted into the support frame 9. Nuts 23 are screwed onto the lower ends of the guide rods 17. By vertically sliding the guide rods 17 into the support frame 9, precise and stable guidance for the vertical movement of the support base 12 can be achieved. Furthermore, by adjusting the nuts 23, the upward support limit position of the support base 12 can be adjusted, making it more flexible to use.

[0036] Four guide rods 17 are provided and arranged in a circular array (at the four corners) relative to the support springs 18. This ensures the stability and reliability of the lifting and lowering action of the support base 12.

[0037] In this steel structure production shearing equipment, the feeding mechanism at the front of the shearing equipment feeds the plate backward (supported on the upper part of the lower blade 8). The plate is positioned by the back gauge device at the rear of the shearing equipment, and the plate is pressed by the pressure cylinder at the front of the shearing equipment to prevent displacement during shearing. The support base 12 is supported upward by the support spring 18. The sliding shaft 20 is located at the bottom of the vertical section of the guide groove 14, and the support plate 11 is located below the plate to be cut (with a small gap, such as 2-5mm). The hydraulic cylinder 3 extends, driving the lower blade holder 7 and the upper blade 4 to move downward. The shearing force of the upper blade 4 and the lower blade 8 shears the steel plate. During the shearing process, the cut steel plate falls onto the support plate 11. Under the weight of the steel plate (steel plates used in traditional steel structure production are relatively heavy), the support base 12 compresses and moves downward against the support spring 18. Simultaneously, the guide groove 14 and the sliding shaft 20 slide and guide each other downwards. When the sliding shaft 20 is located in the inclined section of the guide groove 14, the support column 13 (material support plate 11) flips backward along the rotating shaft 16 until the sliding shaft 20 is at the uppermost end of the inclined section of the guide groove 14. At this time, the steel plate on the material support plate 11 slides obliquely onto the guide groove 10 (the upper end of the guide groove 10 is connected to the material support plate 11). The support seat 12, support column 13, and material support plate 11 are reset under the elastic support of the support spring 18 and the sliding guidance of the sliding shaft 20 and the guide groove 14. The steel plate slides obliquely backward along the guide groove 10 and falls smoothly into the matching material box, ensuring the neatness, reliability, and safety of the material falling, effectively ensuring the space utilization of the material box, improving work efficiency, and greatly reducing the collision damage between plates, thus improving the shearing quality. The overall structure is simple, easy to use, and practical.
