Description

Technical Field

[0001] This utility model relates to a shearing machine capable of longitudinal and transverse shearing, and in particular to its detachable upper shearing mechanism, belonging to the field of shearing machinery and equipment. Background Technology

[0002] When scrap steel plates are recycled for remelting, the scrap steel needs to be cut into small pieces before it can be used. Generally, a gantry shear with a straight cutting blade is used to cut the steel. When the object to be cut is a large / wide steel plate, a concave-convex shear (a stepped combination shear with Chinese patent publication number CN103692013A and a continuous cutting edge longitudinal and transverse composite shear with CN103878433A) or a longitudinal and transverse shear (a longitudinal and transverse gantry shear with Chinese patent publication number CN216177119U) can be used.

[0003] However, in actual scrap steel processing, both gantry shears with "I"-shaped shear blades and longitudinal shears with longitudinal blades are needed. Due to site constraints, shears that can be easily disassembled to change the shear blade structure are required. For example, the detachable multi-blade shear and its gantry shear with Chinese patent publication number CN214602228U can be manufactured into independent longitudinal shear blade seats (lower longitudinal shear seat and upper longitudinal shear blade seat). When needed, they can be installed to become longitudinal shears, and when not needed, they can be removed to restore the "I"-shaped gantry shear. Thus, two shearing functions can be achieved with one machine, which broadens the application scenarios of the equipment.

[0004] However, in practice, such detachable equipment, when used in shearing, requires extremely high reliability of the detachable structure connection. Otherwise, if the fastening screws loosen during shearing, it will cause the longitudinal shearing blade seat to loosen and fail, affecting the shearing effect.

[0005] Therefore, it is necessary to further improve the structure of the existing detachable longitudinal and transverse shearing machine in order to improve the safety and reliability of the equipment during use. Utility Model Content

[0047] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0048] Figure 1A partial structural diagram of a longitudinal and transverse shearing machine using the detachable longitudinal and transverse shearing mechanism of this utility model is shown. The basic structure is similar to the detachable multi-blade shear and its gantry shear with Chinese Patent Publication No. CN214602228U. It includes a shearing frame 1, with a fixed lower blade seat 12 at the bottom. Several lower transverse shear blades 13 are installed on the upper part of the lower blade seat 12 to form lower transverse shearing blades. On the discharge side (front) of the lower blade seat 12, a lower longitudinal shear seat 14 is detachably installed. Two vertical lower longitudinal shear tables 15 are provided on the left and right sides of the lower longitudinal shear seat 14, and lower longitudinal shear blades 16 are installed on the top of each table.

[0049] The upper part of the shearing frame 1 is equipped with an upper blade holder 2 that can move vertically up and down, and the rear part of the upper blade holder 2 is equipped with an upper horizontal shear blade 23 (see Figure 3 , Figure 8 The upper horizontal shearing blade 13, together with the lower horizontal shearing blade 13, forms a horizontal shearing line; an upper vertical shearing base 3 is detachably installed at the lower part of the upper blade holder 2, and upper vertical shear blades 35 are installed on the left and right sides of the upper vertical shearing base 3 (see...). Figure 1 , Figure 9 , Figure 11 The blade, in conjunction with the lower longitudinal shear blade 16, forms two longitudinal shearing lines, which in turn, in conjunction with the transverse shearing blade, form crisscrossing shearing lines. This allows the steel plate to be sheared to be cut into suitable small pieces by feeding it in a single direction.

[0050] The improvement of this utility model lies in the improvement of the detachable mounting structure of the upper longitudinal scissor seat 3 on the upper blade seat 2.

[0051] like Figure 2 , Figure 3 The diagram shows the structure of the upper blade holder 2 after removing the upper longitudinal shear holder 3. The lower part of the upper blade holder 2 is inclined at a certain angle (about 12°) in the horizontal direction. The rear side (material receiving side) of the upper blade holder 2 is provided with a mounting groove for the upper transverse shear blade 23. A blade pad 22 is placed in the mounting groove. Several upper transverse shear blades 23 are then installed and fixed side by side by bolts. Several mounting holes 21 are opened longitudinally in the front-back direction at the lower part of the upper blade holder 2 for fasteners such as fixing bolts of the upper transverse shear blades 23 to pass through.

[0052] In the middle of the inclined bottom surface of the upper cutter holder 2, there is a recessed cutter holder mounting groove 25. The cutter holder mounting groove 25 is also provided with several fixing screw holes 26, so that the upper longitudinal scissor seat 3 can be inserted into the cutter holder mounting groove 25 to achieve positioning and limiting. Then, the upper longitudinal scissor seat 3 is fixed by passing a fastening bolt through the upper longitudinal scissor seat 3 and screwing it into the fixing screw holes 26.

[0053] Furthermore, a limiting boss 27 is provided in the middle of the tool holder mounting groove 25. On the left and right sides of the tool holder mounting groove 25, limiting protrusions 28 can be added to the inclined bottom surface of the upper tool holder 2. The limiting protrusions 28 are in close contact with the left and right side walls of the tool holder mounting groove 25, thereby increasing the area of ​​the positioning and limiting surfaces on the left and right sides of the tool holder mounting groove 25, and providing more reliable positioning and limiting.

[0054] On the front side of the tool holder mounting slot 25, a front base plate 29 is welded and fixed to the bottom of the upper tool holder 2, such as... Figure 6 As shown, the front base plate 29 is preferably welded and fixed to the front side of the bottom of the upper tool holder 2; the front base plate 29 is provided with a clearance hole at the mounting hole 21 so that the mounting hole 21 can pass through; a number of front fastening screw holes 291 extending upward into the tool holder 2 are arranged on the front base plate 29; furthermore, the lower part of the front base plate 29 extends downward and protrudes from the front side of the tool holder mounting groove 25, forming a positioning and limiting on the front side of the tool holder mounting groove 25.

[0055] On the rear side of the tool holder mounting groove 25, there is a rear retaining groove 24, including a rear retaining mounting groove 241 that is lower than or flush with the tool pad 22 mounting groove, and a rear retaining fixing groove 242 located above the rear retaining mounting groove 241 and further recessed into the tool holder 2.

[0056] like Figure 4 , Figure 5 The diagram shows the structure of the upper longitudinal scissor holder 3 (with the upper longitudinal scissor blade 35 installed) before installation. It has a flat tool holder mounting surface 31 that matches the tool holder mounting groove 25. The tool holder mounting surface 31 has several mounting holes 32 that match the fixing screw holes 26, making it easy for the fastening bolts to pass through the mounting holes 32 and be screwed into the fixing screw holes 26, so that the upper tool holder 2 can be fixed. Furthermore, the tool holder mounting surface 31 has a limiting groove 33 in the middle that matches the limiting boss 27. When the tool holder mounting surface 31 is attached to the tool holder mounting groove 25, the limiting groove 33 engages with the limiting boss 27, thereby limiting and positioning the upper tool holder 2 in four directions.

[0057] The front side of the blade mounting surface 31 of the upper longitudinal scissor seat 3 protrudes to form a front latching block 38, which protrudes from the lower blade seat body.

[0058] The rear side of the blade mounting surface 31 of the upper longitudinal scissor seat 3 is recessed to form a rear locking groove 34. The rear locking groove 34 includes a recessed rear locking surface 341 and a rear locking groove 342 located below the rear locking surface 341 and continuing to recess into the upper longitudinal scissor seat 3.

[0059] The upper longitudinal shear seat 3 has several blade fixing holes 36 in the middle of its rear side, and preferably, blade fixing nuts 362 are embedded in the blade fixing holes 36.

[0060] Remove the upper vertical scissor seat 3, lay the corresponding blade pad 22 in the rear groove 24 area behind the upper blade seat 2, and then install the conventional upper horizontal scissor blade 23. This will restore the upper blade seat 2 to the conventional "I" shaped gantry shear.

[0061] When the longitudinal shearing function is required to form a longitudinal and transverse shear, the installation process of the upper longitudinal shear holder 3 is as follows:

[0062] (1) Remove the upper horizontal scissor blade 23 and blade pad 22 in the middle of the upper blade holder 2 to expose the rear retaining groove 24;

[0063] (2) Raise the upper longitudinal shear seat 3 so that the tool holder mounting surface 31 fits against the tool holder mounting groove 25 and the limiting groove 33 catches the limiting boss 27; use screws / bolts to screw into the fixing screw hole 26 through the mounting hole 32; initially fix the upper longitudinal shear seat 3 to the bottom of the upper tool holder 2;

[0064] (3) Install the rear buckle plate 4; one side of the rear buckle plate 4 is smooth, the middle of the other side is smooth, and the upper and lower sides are raised to form buckle strips 42; install the rear buckle plate 4 to the rear side (material receiving side) of the upper cutter seat 2 and the upper longitudinal scissor seat 3, so that the buckle strip 42 of the upper part of the rear buckle plate 4 is fastened into the rear buckle fixing groove 242 of the upper cutter seat 2, and the buckle strip 42 of the lower part of the rear buckle plate 4 is fastened into the rear buckle tightening groove 342 of the upper longitudinal scissor seat 3, and the plane between the two buckle strips 42 is flush with the rear of the upper cutter seat 2 and the upper longitudinal scissor seat 3.

[0065] The rear buckle plate 4 further limits the vertical direction of the rear side of the upper longitudinal scissor seat 3.

[0066] The rear buckle plate 4 has a light hole in the middle. The fixing bolt 45 passes through the mounting hole 21 at the lower part of the upper knife holder 2 and is fixed with the nut. Under this structure, the rear buckle plate 4 is fixed by horizontally set bolts and is not easy to loosen.

[0067] The structure after the rear buckle 4 is installed, such as Figure 7 As shown;

[0068] (4) Install the special blade pad 22 to fill in the gaps on both sides of the rear buckle plate 4, and then install the upper horizontal scissor blade 23;

[0069] On the rear side of the upper longitudinal shear seat 3, using screws, combined with the blade fixing hole 36 and the blade fixing nut 362, the upper transverse protruding blade 37 is installed. The rear side of the upper transverse protruding blade 37 is flush with the rear side of the upper transverse shear blade 23, and both cooperate with the lower transverse shearing blade of the lower transverse shear blade 13 to achieve transverse shearing. By setting the upper transverse protruding blade 37, when the protruding upper longitudinal shear blade 35 cooperates with the lower longitudinal shear blade 16 to perform longitudinal shearing, the upper transverse protruding blade 37 can also cooperate with the lower transverse shear blade 13 in time to perform transverse shearing, avoiding the material block from being stretched because it cannot be cut in time.

[0070] The specific structure after installation, such as Figure 8 , Figure 9 As shown;

[0071] (5) Install the front buckle plate 5; the structure of the front buckle plate 5 is similar to that of the rear buckle plate 4. The upper and lower sides of the inner side have buckle strips. The upper buckle strips fasten to the top plane of the front base plate 29, and the lower buckle strips fasten to the bottom of the front buckle block 38 of the upper longitudinal scissor seat 3. Several light holes are opened on the front buckle plate 5. The fastening screws pass through the light holes and are screwed into the front buckle fixing screw holes 291 on the front base plate 29 to fix the front buckle plate 5 on the front base plate 29.

[0072] The front buckle plate 5 further limits the vertical direction of the front side of the upper longitudinal scissor seat 3.

[0073] The front buckle plate 5 is fixed with horizontally set screws, making it difficult to loosen.

[0074] The detachable longitudinal and transverse shearing mechanism and its longitudinal and transverse shearing machine of this utility model improve the installation reliability of the upper longitudinal shearing seat 3 by additionally using a rear fastening plate 4 and a front fastening plate 5 for vertical fastening when fixing the upper longitudinal shearing seat 3 on the upper blade seat 2. This effectively avoids the possibility of installation failure of the upper longitudinal shearing seat 3 due to loosening of the fastening bolts in the mounting hole 32 caused by vibration during longitudinal and transverse shearing.

[0075] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
