Description

Technical Field

[0001] This utility model relates to the field of disc shear technology, specifically a disc shear with an adjustable function. Background Technology

[0002] In many industrial fields such as metal processing, steel manufacturing, and machinery manufacturing, the disc shear plays an indispensable role as a key shearing equipment. It continuously and longitudinally shears metal sheets through rotating disc blades, cutting sheets and strips into narrow strips or with clean edges. It is widely used in the longitudinal shearing of raw materials for cold-rolled strip steel and in the slitting and rewinding production line of cold-rolled strip steel.

[0003] For example, CN208728779U discloses a disc shearing machine, which includes a frame, an upper cutter shaft and a lower cutter shaft, a number of upper blades and a number of lower blades. A worktable is provided on one side of the frame. Push plates are symmetrically arranged on the worktable to abut against the two sides of a metal plate to make it flat. A drive assembly is provided between the two sets of push plates to drive them to move synchronously in opposite directions or in opposite directions. The drive assembly includes a motor, gears, two sets of racks symmetrically arranged along the gears, and a connecting block. By starting the motor, the rotation of the gears sequentially drives two sets of racks, connecting blocks, and push plates to move in opposite directions, causing the push plates on both sides to contact the sides of the metal plate and drive the sides of the metal plate to become flat. When the metal plate is then passed through the shearing machine, the push plates on both sides play a good limiting role in the metal plate, preventing the metal plate from shifting. Compared with the traditional method, this method reduces the number of operation steps, facilitates the operation of the staff, and improves production efficiency. However, the existing device cannot cut a single material into materials of different widths. It is necessary to cut the same material again to achieve the preset effect. This not only takes a long time and is costly, but also makes it difficult to keep the heavier materials horizontal when cutting them, so there is still a risk of shifting during transportation. Therefore, it is urgent to design a disc shear with adjustment function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a disc shear with an adjustable function to solve the problem mentioned in the background art that the existing device cannot cut a single material into materials of different widths, and requires cutting again after the same material to achieve the preset effect. This not only takes a long time and is costly, but also the device cannot keep heavy materials horizontal when cutting them, so there is still a risk of deviation during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disc shear with an adjustable function, comprising an operating table and a driving mechanism. The driving mechanism is installed at the top of the operating table. The driving mechanism includes a main driving roller and a secondary driving roller. The left ends of the main driving roller and the secondary driving roller are installed at the center of a left limiting plate. The right ends of the main driving roller and the secondary driving roller are inserted into the left end of a right limiting member. The right limiting member is threaded onto the right end of the operating table. Multiple sets of disc shear bodies are installed at the center of the main driving roller and the secondary driving roller. The multiple sets of disc shear bodies are connected by adjusting rods. A limiting mechanism is installed at the front end of the operating table.

[0006] Preferably, a convex groove is provided at the right end of the operating table, and side grooves are provided on both the front and back of the inner wall of the convex groove, with through holes provided inside the side grooves.

[0007] Preferably, the main drive roller and the auxiliary drive roller have the same structure, and the main drive roller drives the bottom auxiliary drive roller to rotate inward synchronously.

[0008] Preferably, the main drive roller includes a drive rod and a servo motor. The right end of the drive rod is fixed with protruding plates at both the top and bottom. The left end of the drive rod passes through a fixed bearing, which is installed at the center of the left limit plate. A gear is fixed to the left end of the drive rod. The servo motor drives the right end of the drive rod to rotate.

[0009] Preferably, the limiting component includes a right limiting plate and two sets of side blocks. Side blocks are fixed on both the front and rear sides of the bottom end of the right limiting plate. Pins are inserted into the center of the two sets of side blocks. Two sets of limiting bearings are installed on the left wall of the right limiting plate. The right ends of the main drive roller and the auxiliary drive roller are inserted into the left side of the two sets of limiting bearings.

[0010] Preferably, the disc shear body has square grooves at both the top and bottom of its center to facilitate installation at the center of the main drive roller and the auxiliary drive roller. Limiting sleeves are fixed on both sides of the disc shear body, and the two sets of opposing limiting sleeves are connected by an adjusting rod.

[0011] Preferably, the limiting mechanism includes a U-shaped frame and a hydraulic cylinder. The hydraulic cylinder is installed inside the U-shaped frame. Slide grooves are opened on both inner walls of the U-shaped frame. A lifting plate is provided at the center of the two sets of slide grooves. The bottom end of the lifting plate is fixed to the top side of the hydraulic cylinder, and a semi-circular block is fixed to the top end of the lifting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This adjustable disc shear features a convex groove on the left side of the operating table for easy and quick installation of limiting components, facilitating the installation of the disc shear body and improving efficiency. Protruding plates fixed to the upper and lower parts of the drive rod allow for easy locking of the disc shear body. A servo motor and gear on the right side of the drive rod enable the main drive roller to drive the auxiliary drive roller on the bottom side for better cutting. Four sets of limiting sleeves fixed to the two walls of the disc shear body can be connected using an adjusting rod. This design allows the two sets of disc shear bodies to be adjusted to different distances, making it easier to cut materials of different widths, improving efficiency and saving time.

[0014] This type of adjustable disc shear uses a sliding groove inside the U-shaped frame to facilitate the lifting of the lifting plate. The semi-circular block fixed at the top of the lifting plate can initially keep the material parallel to the drive mechanism for better cutting, thus improving the production efficiency of finished products. The lifting plate at the top is driven by a hydraulic cylinder to lift and lower, saving time and reducing manual operation. Attached Figure Description

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.

[0021] Please see Figures 1-4 One embodiment provided by this utility model:

[0022] A disc shear with adjustable function is disclosed in this application. The servo motor 225 and hydraulic cylinder 52 used in this application are commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art. The disc shear includes an operating table 1 and a drive mechanism 2. The drive mechanism 2 is installed at the top of the operating table 1. The drive mechanism 2 includes a main drive roller 22 and a secondary drive roller 23. The left ends of the main drive roller 22 and the secondary drive roller 23 are installed at the center of the left limit plate 21. The right ends of the main drive roller 22 and the secondary drive roller 23 are inserted into the left end of the right limit member 24. The right limit member 24 is threaded onto the right end of the operating table 1. Multiple disc shear bodies 3 are installed at the center of the main drive roller 22 and the secondary drive roller 23. The multiple disc shear bodies 3 are connected by an adjusting rod 4. A limit mechanism 5 is installed at the front end of the operating table 1.

[0023] Furthermore, a convex groove 11 is provided on the right end of the operating table 1, and side grooves 111 are provided on both the front and back of the inner wall of the convex groove 11. Through holes 112 are provided inside the side grooves 111 to facilitate the quick installation of the limiting component and improve the installation efficiency.

[0024] As a further feature of this invention, the main drive roller 22 and the auxiliary drive roller 23 have the same structure. The main drive roller 22 drives the auxiliary drive roller 23 on the bottom side to rotate inward synchronously. The main drive roller 22 includes a drive rod 221 and a servo motor 225. The right end of the drive rod 221 is fixed with protruding plates 223 at both the top and bottom. The left end of the drive rod 221 passes through a fixed bearing 222, which is installed at the center of the left limit plate 21. A gear 224 is fixed at the left end of the drive rod 221. The servo motor 225 drives the right end of the drive rod 221 to rotate, which is beneficial for the main drive roller to drive the auxiliary drive roller on the bottom side to rotate, thereby achieving better cutting.

[0025] Furthermore, the limiting component 24 includes a right limiting plate 241 and two sets of side blocks 242. The side blocks 242 are fixed on the front and rear sides of the bottom end of the right limiting plate 241. A pin 243 is inserted into the center of the two sets of side blocks 242. Two sets of limiting bearings 244 are installed on the left wall of the right limiting plate 241. The right ends of the main drive roller 22 and the auxiliary drive roller 23 are inserted on the left side of the two sets of limiting bearings 244, which facilitates installation on the right side of the operating table to facilitate the rotation of the main drive roller and the auxiliary drive roller.

[0026] As a further feature of this invention, the disc shear body 3 has square grooves 31 at both the top and bottom of its center, which facilitates installation at the center of the main drive roller 22 and the auxiliary drive roller 23. Limiting sleeves 32 are fixed on both sides of the disc shear body 3, and the two sets of opposing limiting sleeves 32 are connected by adjusting rods 4. This allows the two sets of disc shear bodies to be adjusted to different distances at will, making it easier to cut materials of different widths, improving efficiency and saving time.

[0027] Furthermore, the limiting mechanism 5 includes a U-shaped frame 51 and a hydraulic cylinder 52. The hydraulic cylinder 52 is installed inside the U-shaped frame 51. Slide grooves 511 are opened on both inner walls of the U-shaped frame 51. A lifting plate 53 is provided at the center of the two sets of slide grooves 511. The bottom end of the lifting plate 53 is fixed to the top side of the hydraulic cylinder 52, and a semi-circular block 54 is fixed to the top of the lifting plate 53. This helps to keep the material initially parallel to the drive mechanism for better cutting and improve the production efficiency of finished products.

[0028] Working principle: In use, the user first pulls out the two sets of pins 243 installed in the convex groove 11 on the right side of the operating table 1, and then pulls the right limit plate 241 horizontally to the right. The square groove 31 inside the disc shear body 3 to be installed is then engaged with the protruding plate 223 at the upper and lower ends of the drive rod 221 for installation. When two adjacent disc shear bodies 3 are spaced at a specified distance by adjusting the rod 4 through the four sets of limit sleeves 32 fixed on the two walls, the right limit plate 241 can be reinstalled. Then, the servo motor 225 is powered on to drive the drive rod 221 at the right end to rotate. The rotation of the drive rod 221 will drive the multiple disc shear bodies 3 installed in the center to rotate. At the same time, the gear 224 at the left end of the drive rod 221 contacts the gear 224 in the auxiliary drive roller 23 to rotate synchronously inward. Finally, the hydraulic cylinder 52 is powered on to lift the lifting plate 53 and raise the semi-circular block 54 to the designated position for feeding materials. The above is the complete working principle of this utility model.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
