Description

Technical Field

[0001] The utility model relates to a large-scale C-shaped keel shearing structure, belonging to the technical field of shearing structures. Background Art

[0002] C-shaped keels are a commonly used construction and decoration material, primarily used in support systems for lightweight steel structures, suspended ceilings, and partition walls. Shaped like the letter "C," they are typically made from cold-rolled steel sheets with a rust-proof surface treatment. They offer excellent corrosion resistance and bending resistance.

[0003] In the prior art, after being processed and formed, the C-shaped keel will be transported horizontally under the action of the keel conveyor track. During this transportation process, it needs to be cut by a shearing structure to make it into a fixed length for subsequent transportation, storage and use. At present, when common shearing structures shear C-shaped keels, they are mostly cut directly in one go. For example, the utility model patent with Chinese patent authorization announcement number CN209830428U discloses a shearing structure for C-shaped or U-shaped keels. When shearing the C-shaped keel, it only uses a shear blade to cut the C-shaped keel once. For small-format C-shaped keels, the one-time shearing method can quickly complete the cutting of the C-shaped keel, but for large-format C-shaped keels, since large-format C-shaped keels are generally thicker, the increase in thickness will cause uneven deformation of the material during shearing. The one-time shearing method can easily cause the edge position of the large-format C-shaped keel to have a bursting phenomenon, which will affect the quality of the product and has the disadvantages of reducing the yield rate and increasing the manufacturing cost of the enterprise. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a large-scale C-shaped keel shearing structure.

[0005] The technical solution of the utility model is as follows:

[0006] The scissors are mounted on a plurality of support members, each of which is connected to a pair of support members, and the support members are connected to the support members to form a plurality of support members.

[0007] Among them, the scissors mounting plate is also provided with a slide rail, the layout direction of the slide rail is parallel to the keel conveying direction, the first mounting plate and the second mounting plate are both slidably connected to the slide rail, the first mounting plate and the second mounting plate are fixedly connected together, and the scissors mounting plate is also provided with a third oil cylinder, the layout direction of the third oil cylinder piston part is parallel to the layout direction of the slide rail, and a connecting block is provided on the third oil cylinder piston part, and the connecting block is fixedly connected to the second mounting plate.

[0008] Among them, the scissors mounting plate is also provided with symmetrically arranged limit blocks, which are arranged on the inlet side of the first scissors and the outlet side of the second scissors. A limit bolt is movably passed through each limit block, and a locking nut is locked on each limit bolt.

[0009] The first mounting plate is further provided with a supporting column, which is movably arranged to penetrate the fixed plate, and a limiting top plate is further provided on the top of the supporting column.

[0010] Among them, the second mounting plate is also provided with a slide, and the mounting blocks on both sides are slidably connected in the slide, and the layout direction of the slide is perpendicular to the keel conveying direction. The second mounting plate is also provided with a symmetrically arranged fourth oil cylinder, and the piston parts of the fourth oil cylinders on both sides are oppositely arranged, and the piston parts of the fourth oil cylinders on both sides are connected to the side walls of the corresponding side mounting blocks.

[0011] Among them, guide blocks are also provided on the mounting blocks on both sides, and a guide rod is provided on the side wall of one of the guide blocks. The guide rod is movably arranged to pass through the other guide block, and the layout direction of the guide rod is parallel to the layout direction of the slide.

[0012] The utility model has the following beneficial effects:

[0013] The utility model arranges the first scissors and the second scissors in sequence along the keel conveying direction on the scissor mounting plate. When shearing the large-format C-shaped keel, the two side edges of the large-format C-shaped keel can pass through the L-shaped grooves on both sides, and the middle part of the large-format C-shaped keel passes between the two side mounting blocks. The second scissors can perform the initial shearing on the passed keel, and the shearing position is the two side edges of the keel. After that, the position where the keel needs to be sheared enters the conveying port, and the first scissors can shear the passed keel again, and the shearing position is the entire keel. Since the side edges of the keel have been cut, the force on the keel is more uniform when the first scissors cuts the keel, so that the deformation of the keel during the shearing process can be very small, so that the edge bursting phenomenon of the keel can be well avoided. Compared with the existing technology, the utility model has the advantages of improving the yield rate and reducing the manufacturing cost of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: Please refer to Figure 1 and Figure 2 This embodiment provides a large-format C-shaped keel shearing structure, comprising a mounting base 1 mounted on an external keel conveying track, a scissor mounting plate 2 fixedly mounted on the top surface of the mounting base 1, and a first scissor 3 and a second scissor 4 mounted on the top surface of the scissor mounting plate 2. In this embodiment, the keel is conveyed from the front side wall of the scissor mounting plate 2 to the rear side wall of the scissor mounting plate 2. The first scissor 3 is positioned behind the second scissor 4, so that the large-format C-shaped keel passes through the second scissor 4 before passing through the first scissor 3 during the conveying process.

[0020] In this embodiment, the first pair of scissors 3 includes a first mounting plate 301 symmetrically arranged on both sides. A first oil cylinder 302 is fixedly arranged on the top surface of each of the first mounting plates 301. The piston portion of each of the first oil cylinders 302 is vertically upward. A fixing plate 303 is arranged above the first oil cylinders 302 on both sides. The bottom surface of the fixing plate 303 is fixedly connected to the piston portion of the first oil cylinders 302 on both sides. A first shearing blade 304 is also fixedly mounted on the bottom surface of the fixing plate 303. A conveying block 305 is arranged below the first shearing blade 304. The conveying block 305 is provided with a conveying port 306 for passing a C-shaped keel. The first shearing blade 304 can be movably inserted into the conveying port 306 from the top of the conveying block 305 to perform corresponding shearing work on the C-shaped keel passing through the conveying port 306.

[0021] In this embodiment, the second pair of scissors 4 includes a second mounting plate 401, the top surface of which is provided with symmetrically arranged mounting blocks 402. L-shaped slots 403 are formed on each side of the mounting blocks 402. The L-shaped slots 403 are used to allow the side edges of the C-shaped keel to pass through. The L-shaped slots 403 are arranged opposite each other, and the ends of the transverse structures of the L-shaped slots 403 on each side are arranged to penetrate the corresponding side mounting blocks 402, so that the middle portion of the C-shaped keel can pass between the two side mounting blocks 402. A second oil cylinder 404 is provided on each side of the mounting blocks 402. The piston portion of each second oil cylinder 404 is movably extended into the L-shaped slot 403 on the corresponding side. The piston portion of each second oil cylinder 404 is provided with a second shearing blade 405 located in the corresponding L-shaped slot 403. Driven by the second oil cylinder 404, the second shearing blade 405 on each side can shear the side edges of the C-shaped keel passing through the corresponding L-shaped slot 403.

[0022] Through the above-mentioned setting, when the large-format C-shaped keel is sheared, the large-format C-shaped keel is transported to the installation base plate 1 through the external keel conveying track. After that, the large-format C-shaped keel continues to be transported under the action of the keel conveying track. The two side edges of the large-format C-shaped keel can pass through the L-shaped grooves 403 on both sides, and the middle part of the large-format C-shaped keel can pass between the mounting blocks 402 on both sides. At this point, the keel conveyor track stops conveying and then starts working by activating the second oil cylinders 404 on both sides. The second oil cylinders 404 on both sides push the second shear blades 405 on both sides to perform the initial shearing on the passing keel, and the shearing position is the side edges of the keel. After that, the keel conveyor track continues to work, and the position where the large-format C-shaped keel to be sheared enters the conveying port 306. At this point, the keel conveyor track stops conveying and then starts working by activating the first oil cylinders 302 on both sides. The first oil cylinders 302 on both sides drive the fixed plate 303 to move so that the first shear blades 304 can shear the passing keel again, and the shearing position is the entire keel. This step completely cuts the large-format C-shaped keel. Because the side edges of the large-format C-shaped keel have been cut by the second shears 4, the force applied to the large-format C-shaped keel by the first shears 3 is more uniform when cutting the large-format C-shaped keel, so that the deformation of the large-format C-shaped keel during the shearing process is very small, which can effectively prevent the large-format C-shaped keel from cracking.

[0023] In order to improve the stability of the first scissors 3 during operation, in this embodiment, four supporting columns 11 distributed in a rectangular shape are further provided on the first mounting plate 301. The four supporting columns 11 are movably arranged to penetrate the fixed plate 303. The fixed plate 303 can slide up and down on the four supporting columns 11. The four supporting columns 11 can provide stability for the movement of the fixed plate 303, thereby improving the stability of the first scissors 3 during operation. A limiting top plate 12 is also provided on the top of the four supporting columns 11. The setting of the limiting top plate 12 can prevent the fixed plate 303 from falling off the four supporting columns 11.

[0024] To accommodate the shearing of large-format C-shaped keels of varying widths, the second mounting plate 401 is further provided with a slideway 13. The mounting blocks 402 on either side are slidably connected within the slideway 13, with the slideway 13 positioned perpendicular to the keel conveying direction. The second mounting plate 401 is also provided with symmetrically arranged fourth cylinders 14, with their pistons positioned opposite each other and connected to the sidewalls of the corresponding mounting block 402. Furthermore, each mounting block 402 is further provided with a guide block 15. A guide rod 16 is provided on the sidewall of one guide block 15, which movably passes through the other guide block 15 and is positioned parallel to the direction of the slideway 13. Through the above-mentioned setting, by starting the fourth oil cylinder 14 on both sides to start movement, the mounting blocks 402 on both sides can be driven to slide in the slide 13. During this process, the guide block 15 will slide along the guide rod 16 to ensure the stability of the mounting blocks 402 on both sides during operation. When the mounting blocks 402 on both sides slide in the slide 13, the distance between the L-shaped grooves 403 on both sides can be adjusted to adapt to the shearing of large-scale C-shaped keels of different widths.

[0025] The above-mentioned shearing method requires controlling the external keel conveyor track to perform multiple stopping and conveying actions. In addition, since it is also necessary to ensure the overlap of the positions of the first scissors 3 and the second scissors 4 during shearing, a complex control program is required, resulting in high production costs and complicated operation. To address this problem, a second embodiment is proposed based on the first embodiment.

[0026] Example 2: Please refer to Figure 1 and Figure 2This embodiment provides a large-scale C-shaped keel shearing structure, including all the structures of the first embodiment. Furthermore, the scissor mounting plate 2 is further provided with symmetrically arranged slide rails 5. The layout direction of the slide rails 5 on both sides is parallel to the keel conveying direction. The first mounting plate 301 and the second mounting plate 401 are both slidably connected to the slide rails 5. At the same time, the first mounting plate 301 and the second mounting plate 401 are fixedly connected together. The scissor mounting plate 2 is also provided with symmetrically arranged third oil cylinders 6. The layout direction of the piston portions of the third oil cylinders 6 on both sides is parallel to the layout direction of the slide rails 5. The piston portions of the third oil cylinders 6 on both sides are fixedly provided with connecting blocks 7. The connecting blocks 7 on both sides are fixedly connected to the second mounting plate 401. The scissors mounting plate 2 is further provided with limit blocks 8 that are symmetrically arranged front to back. The limit blocks 8 are provided on both the inlet side of the first scissors 3 and the outlet side of the second scissors 4. A limit bolt 9 is movably inserted into each limit block 8, and a locking nut 10 is locked into each limit bolt 9. The limit bolt 9 is fixed to the limit block 8 by the setting of the locking nut 10. The setting of the limit bolts 9 satisfies the requirements according to their positions, that is, the limit bolts 9 distributed on the front side of the scissors mounting plate 2 can abut against the front side wall of the second mounting plate 401, and the limit bolts 9 distributed on the rear side of the scissors mounting plate 2 can abut against the rear side wall of the first mounting plate 301.

[0027] With the aforementioned arrangement, when shearing a large-format C-shaped keel, the position of the limiting bolt 9 is first adjusted. This allows the second shears 4 to be positioned where the large-format C-shaped keel is to be sheared when the first mounting plate 301 abuts the limiting bolt 9 at the corresponding position. Similarly, when the second mounting plate 401 abuts the limiting bolt 9 at the corresponding position, the first shears 3 to be positioned where the large-format C-shaped keel is to be sheared. Subsequently, the third oil cylinders 6 on both sides are activated to move the second mounting plate 401 and the first mounting plate 301 via the connecting block 7, thereby adjusting the positions of the first and second shears 3 and 4. Once the first mounting plate 301 abuts the limiting bolt 9 at the corresponding position, the third oil cylinders 6 on both sides are closed. Afterwards, the large-format C-shaped keel is transported to the mounting base plate 1 via the external keel conveyor track and continues to be transported under the action of the keel conveyor track until the two sides of the large-format C-shaped keel pass through the L-shaped grooves 403 on both sides and the middle part of the large-format C-shaped keel passes between the two mounting blocks 402 on both sides. After that, when the large-format C-shaped keel enters the second shears 4 at the position where it needs to be cut, the keel conveyor track stops and the second oil cylinders 404 on both sides are activated to start working. The second oil cylinders 404 on both sides push the second shear blades 405 on both sides to perform the initial shearing of the passing keel, and the shearing position is the two sides of the keel. After this, the third oil cylinders 6 on both sides are controlled to start working, so that the second mounting plate 401 contacts the corresponding position of the limit screw. At this time, the position where the large-format C-shaped keel needs to be cut is moved to the conveying port 306. By controlling the first oil cylinders 302 on both sides to start working, the entire keel can be sheared and cut. After cutting, there is no need to continue conveying the keel conveyor track. The cut large-format C-shaped keel is ejected and the next cutting work can be carried out.

[0028] The above method does not require multiple starts and stops of the external keel conveying track. At the same time, a hard limit method is adopted, that is, the limit bolt 9 abuts against the first mounting plate 301 and the second mounting plate 401 to determine the shear position on both sides. There is no need to add a complex control program, which has the advantages of reducing production costs and simple operation.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
