Description

Technical Field

[0001] This utility model relates to the field of disc cutter technology, specifically to a longitudinal shearing disc cutter. Background Technology

[0002] Longitudinal shearing discs are key equipment in the field of sheet metal processing, and are widely used in industries such as steel, non-ferrous metals, and automobile manufacturing. They are mainly used to cut wide metal coils or sheets into narrower specifications along the longitudinal direction, and their performance directly affects the shearing efficiency, cut quality, and production economy.

[0003] The existing slitting disc cutter has the following shortcomings:

[0004] 1. Traditional slitting disc blades mostly adopt an integral structure design, with the blade body being a complete circular piece. The blade and the blade body cannot be separated. During long-term high-speed shearing operations, the blade is prone to local wear, dulling, or chipping due to continuous friction and impact with metal materials. Due to the limitations of the integral structure, even if only the blade is partially damaged, the entire disc blade body must be replaced. The unworn parts cannot be used, resulting in serious waste of resources.

[0005] 2. Traditional slitting disc cutters often use straight cutting edges or simple toothed designs, which result in insufficient gripping force on the material during the cutting process. When processing thin, soft, or smooth metal materials, material slippage and displacement are likely to occur, leading to deviations in the cutting position and uneven cuts, thus affecting product quality. Utility Model Content

[0006] The purpose of this invention is to provide a longitudinal shearing disc cutter.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A slitting disc cutter is provided, including a cutter head body, a disc cutter body, a limiting plate, and a fixing mechanism. The disc cutter body is formed by splicing at least two fan-shaped cutter body units to form a circular structure. The fixing mechanism is located inside the disc cutter body and is used to detachably connect adjacent fan-shaped cutter body units. Each fan-shaped cutter body unit can be individually disassembled and replaced through the fixing mechanism. The fixing mechanism includes a locking seat, a locking block, and a locking groove. A locking seat is fixed on one side of each fan-shaped cutter body unit inside the disc cutter body. A locking block is symmetrically arranged on one side of the locking seat. A locking groove is opened on the side of each fan-shaped cutter body unit away from the locking seat. In two adjacent fan-shaped cutter body units, the locking block of one fan-shaped cutter body unit is adapted to the locking groove of the other fan-shaped cutter body unit. An arc-shaped cutting edge is provided on the edge of each fan-shaped cutter body unit inside the disc cutter body, and cutting teeth are opened on both sides of the cutting edge of the arc-shaped cutting edge.

[0009] Preferably, a fixed blade post is fixed on one side of the cutter head body, the outer diameter of the fixed blade post is adapted to the inner diameter of the disc cutter body, a locking nut is provided on one side of the cutter head body, and a locking bolt is provided on one side of the limiting plate.

[0010] Preferably, the inside of the traffic restriction plate has several sets of locking screw holes arranged in a ring array, the inside of the disc cutter body has several sets of locking screw holes arranged in a ring array, and the inside of the cutter body has several sets of locking screw holes arranged in a ring array. The locking bolts pass through the locking screw holes one, two and three respectively and are threadedly connected to the locking nuts.

[0011] Preferably, the cutting edge of the arc-shaped blade is made of high-speed steel, and the teeth of each pair of adjacent fan-shaped blade units combine to form a V-shaped serrated structure.

[0012] Preferably, the fixing mechanism further includes a push-pull ring, a pull rod, a spring, a lever, and a hinge rod. The push-pull ring is slidably connected in a through groove inside the locking seat. The pull rod is fixed to one side of the push-pull ring. The spring is wrapped around the surface of the push-pull ring, and both ends of the spring are fixed between the push-pull ring and the disc cutter body, respectively. A push-pull groove is provided in the middle of the push-pull ring. The lever is movably connected to the inside of the push-pull ring through the push-pull groove. The hinge rod is fixed in the middle of the lever and is hinged inside the locking seat.

[0013] Preferably, the disc cutter body has a relief groove inside that matches the pull rod, and a hand-held ball head is fixed at the end of the pull rod.

[0014] Preferably, the lever has a V-shaped structure, and a lever seat is provided at the end of the lever away from the push-pull ring. The lever seat is slidably connected inside the locking seat. The lever seat has a lever groove inside, which is adapted to the lever. The lever seat is fixedly connected to the locking block.

[0015] Preferably, the locking block has a semi-circular structure, and a spring is fixed between the two sets of locking blocks. The upper and lower sides of the locking groove are provided with a folding slope that is adapted to the locking block.

[0016] The beneficial effects of this utility model are:

[0017] 1. The longitudinal shearing disc cutter of this utility model is composed of multiple fan-shaped cutter units. When the blade of a certain fan-shaped cutter unit is locally worn or dulled, it is not necessary to replace the entire disc cutter body. The worn unit can be disassembled and replaced individually by simply unlocking the fixing mechanism. Compared with the traditional integral disc cutter, it can accurately replace the worn parts, avoid the scrapping of the entire cutter due to local damage, maximize the use value of the unworn units, extend the overall service life of the cutter, realize the efficient use of resources, greatly reduce the waste of cutter materials, and significantly reduce the equipment maintenance and use costs.

[0018] 2. The longitudinal shearing disc blade of this utility model has an arc-shaped cutting edge made of high-speed steel on the edge of the fan-shaped blade unit of the disc blade body, which ensures long-lasting sharpness, effectively resists wear caused by material friction, maintains the sharpness of the cutting edge, reduces the frequency of frequent replacement of the blade unit due to blade dulling, and at the same time ensures that the cutting edge can always stably transmit shearing force during the shearing process, avoiding the decline in shearing quality caused by blade wear.

[0019] 3. The longitudinal shearing disc blade of this utility model has a V-shaped structure after the combination of the blade teeth on both sides. This structure can enhance the material gripping force, prevent shear slippage, and create lateral pressure between the blade teeth and the material contact surface. This effectively prevents the material from slipping or shifting during high-speed shearing, ensuring the accuracy of the shearing position. It can also concentrate the dispersed shearing force at the tip of the blade, so that the material is subjected to a strong shearing impact force at the moment of contact, accelerating the material fracture process. Compared with ordinary straight blade teeth, V-shaped blade teeth can achieve material shearing with less energy consumption, improving the efficiency of longitudinal shearing operations.

[0020] 4. The longitudinal shearing disc cutter of this utility model effectively eliminates the gap between components through the multi-layer through-type fixing method of locking bolts, ensuring that the disc cutter body can stably follow the cutter disc body to rotate synchronously, avoiding vibration or displacement caused by relative sliding during the shearing process, and ensuring shearing accuracy. The fixed blade column plays a precise positioning role, ensuring that the disc cutter body and the cutter disc body are aligned on the axis. The improved assembly coaxiality reduces the centrifugal force deviation during rotation. Attached Figure Description

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0032] Reference Figures 1 to 7 The slitting disc cutter shown includes a cutter head body 1, a disc cutter body 2, a limiting plate 3, and a fixing mechanism 4. The disc cutter body 2 is formed by splicing at least two fan-shaped cutter body units to form a circular structure. The fixing mechanism 4 is located inside the disc cutter body 2 and is used to detachably connect adjacent fan-shaped cutter body units. Each fan-shaped cutter body unit can be individually disassembled and replaced through the fixing mechanism 4. The fixing mechanism 4 includes a locking seat 401, a locking block 410, and a locking groove 412. Each fan-shaped cutter body unit inside the disc cutter body 2 has a locking mechanism fixed on one side. The locking seat 401 has symmetrically arranged locking blocks 410 on one side. Each fan-shaped cutter unit in the disc cutter body 2 has a locking groove 412 on the side away from the locking seat 401. In two adjacent fan-shaped cutter units, the locking block 410 of one fan-shaped cutter unit is matched with the locking groove 412 of the other fan-shaped cutter unit. Each fan-shaped cutter unit in the disc cutter body 2 has an arc-shaped cutting edge 201 on its edge, and the cutting edge of the arc-shaped cutting edge 201 has cutting teeth 202 on both sides.

[0033] A fixed blade post 101 is fixed to one side of the cutter head body 1. The outer diameter of the fixed blade post 101 is adapted to the inner diameter of the disc cutter body 2. A locking nut 105 is provided on one side of the cutter head body 1, and a locking bolt 102 is provided on one side of the limiting plate 3. The limiting plate 3 has several sets of locking screw holes 103 arranged in a ring array inside. The disc cutter body 2 has several sets of locking screw holes 106 arranged in a ring array inside. The cutter head body 1 has several sets of locking screw holes 104 arranged in a ring array inside. The locking bolt 102 passes through the locking screw holes 103, 104, and 106 respectively and is threaded to the locking nut 105. The disc cutter body 2 is assembled from the fixed blade post 101 on one side of the cutter head body 1, and then the locking bolt 102 passes through the locking screw holes 103, 104, and 106 respectively. The locking screw hole 103 of the limiting plate 3, the locking screw hole 106 of the disc cutter body 2, and the locking screw hole 104 of the cutter body 1 are finally fastened to the locking nut 105 on the other side of the cutter body 1 to achieve axial compression and form an integral rigid structure, thereby fixing the disc cutter body 2 and allowing the disc cutter body 2 to rotate together with the cutter body 1. The multiple fan-shaped cutter body units of the disc cutter body 2, the symmetrical locking block 410 on the locking seat 401 of one fan-shaped cutter body unit, are embedded in the locking groove 412 of another fan-shaped cutter body unit. The locking block 410 has a semi-circular structure. The spring 411 between the two sets of locking blocks 410 provides preload force, so that the locking block 410 fits tightly against the converging inclined surface 413 of the inner wall of the locking groove 412 to achieve circumferential fixation.

[0034] The cutting edge of the arc-shaped blade 201 is made of high-speed steel. The blade teeth 202 of each pair of adjacent fan-shaped blade units are combined to form a V-shaped serrated structure. The arc-shaped blade 201 at the edge of the fan-shaped blade unit contacts the material to be sheared. The V-shaped blade teeth 202 enhance the material's biting force, achieving efficient longitudinal shearing. The arc-shaped blade teeth 201 of adjacent fan-shaped blade units are combined to form a complete circular blade. The blade teeth 202 are spliced ​​together to form a V-shaped structure, enhancing the shearing ability.

[0035] The fixing mechanism 4 also includes a push-pull ring 402, a pull rod 403, a spring 404, a lever 406, and a hinge rod 407. The push-pull ring 402 is slidably connected in a through groove inside the locking seat 401. The pull rod 403 is fixed to one side of the push-pull ring 402. The spring 404 is wrapped around the surface of the push-pull ring 402, and its two ends are respectively fixed between the push-pull ring 402 and the disc cutter body 2. A push-pull groove 405 is provided in the middle of the push-pull ring 402. The lever 406 is movably connected to the inside of the push-pull ring 402 through the push-pull groove 405. The hinge rod 407 is fixed to the lever. The middle part of 406, and the hinge rod 407 is hinged inside the locking seat 401. When the blade of a certain fan-shaped blade unit of the disc blade body 2 is locally worn or dulled, the fan-shaped blade unit can be removed from the adjacent fan-shaped blade unit to remove the worn or dulled fan-shaped blade unit and replace it with a new fan-shaped blade unit. During disassembly, by holding the ball end of the pull rod 403, the push-pull ring 402 is pulled to slide along the through groove inside the locking seat 401, compressing the spring 404. When the push-pull ring 402 moves, it drives the actuating rod 406 to rotate around the hinge rod 407 through the push-pull groove 405.

[0036] The disc cutter body 2 has a clearance groove inside that matches the pull rod 403, and a hand-held ball head is fixed at the end of the pull rod 403. The actuating rod 406 has a V-shaped structure, and an actuating seat 408 is provided at the end of the actuating rod 406 away from the push-pull ring 402. The actuating seat 408 is slidably connected to the inside of the locking seat 401. The actuating seat 408 has an actuating groove 409 inside that matches the actuating rod 406, and the actuating seat 408 is fixedly connected to the locking block 410. The actuating rod 406 pushes the actuating seat 408 to slide inward through the actuating groove 409. The actuating seat 408 drives the locking block 410 to compress the second spring 411, causing the locking block 410 to disengage from the locking groove 411. The converging inclined surface 413 of 2 releases the lock between the adjacent fan-shaped cutter body unit and the fan-shaped cutter body unit. At this time, the fan-shaped cutter body unit is in an active state. Loosen the locking nut 105 to remove the limiting plate 3 and take out the target fan-shaped cutter body unit. The worn fan-shaped cutter body unit can be disassembled and replaced separately without replacing the entire disc cutter body 2, which reduces the cost of use and improves the service life of the cutter. Then, align the locking block 410 of the new fan-shaped cutter body unit with the locking groove 412 of the adjacent fan-shaped cutter body unit, release the pull rod 403 to reset the spring 404 and drive the locking block 410 to lock. Reinstall the limiting plate 3 and tighten the locking bolt 102 and locking nut 105 to complete the replacement.

[0037] The locking block 410 has a semi-circular structure, and a second spring 411 is fixed between the two sets of locking blocks 410. The upper and lower sides of the locking groove 412 are provided with a retractable inclined surface 413 that is adapted to the locking block 410. The semi-circular structure of the locking block 410 and the retractable inclined surface 413 cooperate to have both guiding and anti-loosening functions. The second spring 411 forms an elastic support between the two sets of locking blocks 410, which can compensate for the assembly gap and wear after long-term use, prevent the unit connection from becoming loose or shaking, and extend the service life of the locking components.
