Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, and in particular to a metal slitting machine cutting device. Background Technology
[0002] Traditional slitting machines require cutting devices to separate products of different sizes according to processing needs, necessitating adaptive adjustments to the spacing between the cutters. However, most current cutting devices employ a fixed connection between the cutter and the drive handle, making it impossible to flexibly adjust the cutter spacing according to the target slitting size and thus failing to meet multi-specification processing requirements. Some devices achieve spacing adjustment by adding a cutter holder, using it as an intermediate carrier to assemble the cutter, and then completing the installation through the cooperation of the cutter holder and the drive handle. However, this adjustment process is extremely cumbersome: the cutter must first be removed from the cutter holder, then the cutter holder must be separated from the drive handle, and after the spacing is adjusted, the cutter holder must be reinstalled on the drive handle, and the cutter reassembled onto the cutter holder. These complex disassembly and assembly steps not only increase operational difficulty but also significantly extend adjustment time, severely reducing overall processing efficiency. Utility Model Content
[0003] To address the aforementioned shortcomings, the purpose of this invention is to propose a metal slitting machine cutting device that allows for simple adjustment of the tool spacing and eliminates the need for secondary tool assembly.
[0004] To achieve this objective, the present invention adopts the following technical solution: A metal slitting machine cutting device includes a drive handle and several annular cutter holders. The annular cutter holders are sequentially sleeved on the outer wall of the drive handle. Each annular cutter holder is equipped with an annular cutter and a rubber wheel. Each annular cutter holder includes a mounting portion, a connecting portion, and a positioning element. The mounting portion is coaxially sleeved on the outer wall of the drive handle. The connecting portion is connected to one side of the mounting portion. A positioning hole is pre-set on the periphery of the mounting portion. The positioning element is threaded into the positioning hole, and its end extends into the positioning hole until it tightly abuts against the outer wall of the drive handle. The annular cutter is interference-fitted with the connecting portion, and the rubber wheel is interference-fitted with the connecting portion, with one side of the rubber wheel tightly against the annular cutter.
[0005] Preferably, in the above-mentioned metal slitting machine cutting device, the annular cutter holder further includes a mounting component, the side wall of the mounting component is provided with a first mounting hole; the rubber wheel is provided with a second mounting hole corresponding to the position of the first mounting hole; the mounting component passes through the second mounting hole and the annular cutter in sequence, and then connects to the first mounting hole of the mounting component.
[0006] Preferably, in the above-mentioned metal slitting machine cutting device, at least three positioning holes are provided, and the three positioning holes are symmetrically distributed along the circumferential direction of the mounting part, and each positioning hole is provided with a corresponding positioning element.
[0007] Preferably, in the above-mentioned metal slitting machine cutting device, the diameter of the mounting part is larger than the diameter of the connecting part, so that a ladder structure is formed between the mounting part and the connecting part.
[0008] Preferably, in the above-mentioned metal slitting machine cutting device, the connecting part and one side of the mounting part are integrally formed.
[0009] The beneficial effects of this utility model are: (1) The ring tool holder consists of a mounting part, a connecting part and a positioning part. Its assembly structure design combines stability and reliability: the mounting part is coaxially sleeved on the outer wall of the transmission tool holder, the connecting part is fixedly connected to one side of the mounting part, and the ring tool is tightly assembled to the connecting part by interference fit; in addition, the mounting part has a positioning hole pre-machined around its periphery, the positioning part is connected to the positioning hole by thread fit, and the end of the positioning part extends into the interior of the positioning hole until it is tightly abutted against the outer wall of the transmission tool holder. This design can achieve radial and firm locking between the ring tool holder and the transmission tool holder, ensuring the overall structural stability after assembly, effectively avoiding the phenomenon of loosening or falling off of parts during the cutting operation, and ensuring the machining accuracy.
[0010] (2) When the size of the segmented product needs to be adjusted according to the processing requirements, thanks to the direct assembly structure of the ring cutter and the connecting part, the operator only needs to loosen the positioning part to move the mounting part along the axis of the transmission tool holder and complete the tool spacing adjustment according to the target size. This design fundamentally eliminates the cumbersome steps of "disassembling and assembling the cutter and rubber wheel with the tool holder, disassembling and assembling the tool holder with the transmission tool holder, and reassembling the cutter back into the tool holder" in the traditional adjustment method. There is no need to reassemble the ring cutter and the connecting part, which greatly shortens the spacing adjustment time and significantly improves the overall processing efficiency.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0017] like Figures 1-4As shown, a metal slitting machine cutting device includes a transmission blade holder 11 and several annular blade holders 12. The annular blade holders 12 are sequentially sleeved on the outer wall of the transmission blade holder 11. Each annular blade holder 12 is provided with an annular cutter 13 and a rubber wheel 131. Each annular blade holder 12 includes a mounting portion 14, a connecting portion 15, and a positioning element 16. The mounting portion 14 is coaxially sleeved on the outer wall of the transmission blade holder 11. The connecting portion 15 is connected to one side of the mounting portion 14. A positioning hole 17 is pre-set on the periphery of the mounting portion 14. The positioning element 16 is threadedly connected to the positioning hole 17, and its end extends into the positioning hole 17 until it tightly abuts against the outer wall of the transmission blade holder 11. The annular cutter 13 is press-fitted with the connecting portion 15, and the rubber wheel 131 is press-fitted with the connecting portion 15, with one side of the rubber wheel 131 tightly abutting against the outer wall of the transmission blade holder 11. The ring cutter 13 and the ring cutter holder 12 are composed of a mounting part 14, a connecting part 15, and a positioning element 16. The assembly structure design combines stability and reliability: the mounting part 14 is coaxially sleeved on the outer wall of the transmission tool holder 11, the connecting part 15 is fixedly connected to one side of the mounting part 14, and the ring cutter 13 is tightly assembled to the connecting part 15 by interference fit; in addition, the mounting part 14 has a positioning hole 17 pre-machined around its periphery, and the positioning element 16 is threadedly connected to the positioning hole 17, and the end of the positioning element 16 extends into the positioning hole 17 until it tightly abuts against the outer wall of the transmission tool holder 11. This design can achieve radial and firm locking between the ring cutter holder 12 and the transmission tool holder 11, ensuring the overall structural stability after assembly, effectively avoiding the loosening or falling off of parts during the cutting operation, and ensuring machining accuracy.
[0018] It is worth noting that when the size of the segmented product needs to be adjusted according to processing requirements, thanks to the direct assembly structure of the ring cutter 13 and the connecting part 15, the operator only needs to loosen the positioning part 16 to move the mounting part 14 along the axis of the transmission tool holder 11 and complete the tool spacing adjustment according to the target size. This design fundamentally eliminates the cumbersome steps of "disassembling and assembling the cutter and rubber wheel 131 with the tool holder, disassembling and assembling the tool holder with the transmission tool holder 11, and reassembling the cutter back into the tool holder" in the traditional adjustment method. There is no need to reassemble the ring cutter 13 and the connecting part 15, which greatly shortens the spacing adjustment time and significantly improves the overall processing efficiency.
[0019] In this embodiment of the metal slitting machine cutting device, the annular cutter holder 12 further includes a mounting component 121. The side wall of the mounting part 14 has a pre-set first mounting hole 18. The rubber wheel 131 has a second mounting hole 19 corresponding to the position of the first mounting hole 18. The mounting component 121 passes through the second mounting hole 19 and the annular cutter 13 in sequence, and then connects to the pre-set first mounting hole 18 of the mounting part 14. The annular cutter 13 achieves radial centering and initial fixation through an interference fit with the connecting part 15, and also forms a secondary locking in the axial and circumferential directions through the threaded connection between the mounting component 121 and the first mounting hole 18 and the second mounting hole 19. The double fixing structure can effectively offset the radial impact force and circumferential torque during slitting and cutting, and avoid the cutter from slight displacement or loosening due to vibration. This design further reduces the risk of parts falling off during the cutting operation and ensures the consistency of slitting size accuracy. It should be specifically noted that the positioning component 16 and the mounting component 121 can be fixed bolts, both of which can be obtained through market procurement.
[0020] In some embodiments of the metal slitting machine cutting device, at least three positioning holes 17 are provided, and the three positioning holes 17 are symmetrically distributed along the circumference of the mounting part 14. Each positioning hole 17 is provided with a corresponding positioning element 16. The positioning elements 16 of the three symmetrically distributed positioning holes 17 simultaneously apply radial clamping force to the transmission cutter holder 11, forming a "triangular stable constraint structure." This ensures that the contact pressure between the mounting part 14 and the transmission cutter holder 11 is evenly distributed along the circumference, avoiding localized overload caused by single or asymmetrical positioning. Even when high-frequency vibration or instantaneous impact occurs during slitting cutting, the balanced clamping force can effectively disperse the load, preventing deformation and cracking of the mounting part 14 due to localized stress concentration, and significantly improving the structural durability of the cutter holder under long-term high-load conditions.
[0021] In some embodiments of the metal slitting machine cutting device, the diameter of the mounting part 14 is larger than the diameter of the connecting part 15, so that a ladder structure is formed between the mounting part 14 and the connecting part 15; such a design facilitates installation and also facilitates the ring cutter 13 to perform slitting work after the ring cutter 13 is installed with the connecting part 15.
[0022] In this embodiment of the metal slitting machine cutting device, the connecting part 15 and one side of the mounting part 14 are integrally formed; such a design can effectively avoid cracking and deformation problems, thereby improving the structural durability of the annular cutter holder 12 under long-term high-load conditions.
[0023] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
