Description

Technical Field

[0001] This utility model relates to the field of steel pipe production and processing technology, and in particular to a dust-removing strip steel slitting machine. Background Technology

[0002] In the modern steel processing industry, especially for the production and processing of various pipes such as high-frequency straight seam welded pipes, polygonal steel pipes, diamond-shaped pipes, and zinc-aluminum-magnesium steel pipes, strip steel slitting machines play a crucial role. They can longitudinally cut wide strip steel to predetermined width specifications, providing raw materials with precise dimensions for subsequent pipe forming.

[0003] With the continuous expansion of production scale and increasingly stringent environmental protection requirements, traditional strip steel slitting machines have exposed numerous problems. On the one hand, the high-speed shearing process of strip steel generates a large amount of metal dust. This dust not only permeates the production workshop, polluting the working environment and endangering the health of operators, such as causing respiratory diseases with long-term inhalation, but also affects the quality of subsequent pipe processing if the dust adheres to the strip steel surface. For example, in the welding process, dust mixed in can lead to weak welds, defects such as incomplete welds and missing welds, reducing the overall product qualification rate. Moreover, scattered and accumulated dust accelerates the wear and tear of equipment components, shortens equipment lifespan, increases equipment maintenance costs and downtime, and greatly hinders the company's efficient and continuous production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a dust removal strip steel slitting machine.

[0005] This utility model is achieved through the following technical solution:

[0006] A dust-removing strip steel slitting machine includes a machine body, a support frame installed at the top of the machine body, lifting components symmetrically installed on the support frame, two lifting components connected to a material roller, a top frame supported at the top of the support frame, a blower installed on the top frame, a drive mechanism installed inside the support frame, the drive mechanism being located at the bottom of the material roller, the drive mechanism being connected to a blade changing mechanism, a chip removal pipe provided at the bottom of the machine body, and an exhaust fan installed on the chip removal pipe.

[0007] As can be seen, in the above technical solution, the tool changing mechanism can adjust the tool on the drive mechanism, so that the required tool can be changed according to the processing needs. Then, the lifting component can adjust the material roller to make the material roller cooperate with the tool. Then, the drive motor connected to the material roller runs, and in conjunction with the drive mechanism, the strip steel can be longitudinally sheared. During the processing, the blower at the top runs and blows air downwards, thereby blowing the dust generated during the processing downwards. At the same time, in conjunction with the operation of the exhaust fan, a negative pressure is formed in the chip removal pipe, which causes the dust to accumulate quickly and enter the chip removal pipe, and then be discharged from the bottom of the chip removal pipe, achieving an automatic dust removal effect.

[0008] Optionally, in one possible implementation, two lifting components are provided, each including a top box and a hydraulic lifting rod. The hydraulic lifting rods are symmetrically mounted on the bottom of the top box, and a drive motor connected to the end of the material roller is installed inside one of the top boxes. It can be seen that in the above technical solution, the synchronous extension and retraction of the hydraulic lifting rods connected to the bottom of each top box allows for the coordinated adjustment of the distance between the material roller and the cutter. Furthermore, during operation, the drive motor can drive the material roller to rotate, thus discharging the material.

[0009] Optionally, in one possible implementation, one end of the drive mechanism is fitted with an outer plate connected to a bracket, and the other end of the drive mechanism is connected to an end plate. A bushing mounted on the bracket is connected to the outer side of the end plate. The drive mechanism includes a first motor, a drive rod, a drive gear, a follower gear, and a tool holder. The first motor is mounted on the outer plate, and its output end is connected to a drive rod rotatably connected to the outer plate. A drive gear is mounted at the end of the drive rod, and the drive gear meshes with multiple follower gears. Each follower gear is connected to a tool holder, and each tool holder is rotatably connected to the end plate. Multiple cutting tools are mounted on each tool holder. It can be seen that in the above technical solution, the operation of the first motor causes each follower gear to drive the corresponding tool holder to rotate, thereby enabling the cutting tools on each tool holder to work.

[0010] Optionally, in one possible implementation, the tool changing mechanism includes a second motor, a rotating rod, a first gear, and a gear sleeve. The second motor is mounted on a bracket, and its output end is connected to the rotating rod. The first gear is mounted on the end of the rotating rod and is rotatably connected to the gear sleeve. The gear sleeve is rotatably mounted on the bracket, and it has multiple shaft holes, each containing a tool holder rotatably connected to it. It can be seen that in the above technical solution, the operation of the second motor allows for adjustment of the material roller's engagement with the corresponding tool holder, thereby enabling the selection of a tool for processing according to requirements.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes the combined action of a blower on the top frame blowing downwards and a chip removal pipe and exhaust fan at the bottom of the machine to effectively remove metal debris and dust generated during the strip steel slitting process. This prevents dust from polluting the workshop environment and harming the health of operators, while also preventing dust from adhering to the strip steel and affecting the quality of subsequent pipe processing, reducing welding defects, improving product qualification rate, and ensuring smooth production.

[0013] Meanwhile, the tool holder position can be easily adjusted through the cooperation of the second motor, rotating rod, gear and gear sleeve, realizing the rapid replacement of the tool on the drive mechanism. Operators can quickly switch to the appropriate tool according to the requirements of different strip processing widths and materials, enhancing the versatility and flexibility of the equipment, eliminating the need for complicated manual operation and long downtime, and improving production efficiency.

[0014] In addition, the hydraulic lifting rods of the two lifting components extend and retract synchronously to precisely adjust the distance between the material roller and the cutter, adapting to the processing of strip steel of different thicknesses. Combined with the gear transmission system driven by the first motor in the drive mechanism, it stably drives the cutter bar and the cutter to ensure the slitting accuracy of the strip steel, reduce material waste, extend the service life of the equipment, and reduce equipment maintenance costs and downtime.

[0022] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components.

[0023] like Figure 1-4 As shown, this embodiment provides a dust-removing strip steel slitting machine, including a machine body 1. A bracket 2 is installed at the top of the machine body 1. Lifting components 3 are symmetrically installed on the bracket 2. The two lifting components 3 are connected to a material roller 4. A top frame 5 is supported at the top of the bracket 2. A blower 6 is installed on the top frame 5. A drive mechanism 7 is installed inside the bracket 2. The drive mechanism 7 is located at the bottom of the material roller 4. The drive mechanism 7 is connected to a blade changing mechanism 8. A chip removal pipe 9 is provided at the bottom of the machine body 1. An exhaust fan 10 is installed on the chip removal pipe 9.

[0024] In practice, the tool changing mechanism 8 operates to adjust the tools on the drive mechanism 7, allowing for tool replacement according to processing requirements. Then, the lifting assembly 3 adjusts the material roller 4 to engage with the tool. The drive motor connected to the material roller 4 operates in conjunction with the drive mechanism 7 to perform longitudinal shearing on the strip steel. During processing, the top blower 6 operates, blowing downwards to remove dust generated during processing. Simultaneously, the exhaust fan 10 creates negative pressure inside the chip removal pipe 9, causing dust to accumulate rapidly and enter the chip removal pipe 9, which is then discharged from the bottom, achieving automatic dust removal.

[0025] There are two lifting components 3. Each lifting component 3 includes a top box 301 and a hydraulic lifting rod 302. The hydraulic lifting rod 302 is symmetrically installed at the bottom of the top box 301, and a drive motor connected to the end of the material roller 4 is installed in one of the top boxes 301.

[0026] In practice, the hydraulic lifting rods 302 connected to the bottom of each top box 301 extend and retract synchronously, so that the two top boxes 301 can support the material roller 4 to rise and fall synchronously. This allows for the adjustment of the distance between the material roller 4 and the cutter. During operation, the drive motor can drive the material roller 4 to rotate and discharge the material.

[0027] One end of the drive mechanism 7 is fitted with an outer plate 11 connected to the bracket 2, and the other end of the drive mechanism 7 is connected to an end plate 12. A bushing 13 mounted on the bracket 2 is connected to the outer side of the end plate 12. The drive mechanism 7 includes a first motor 701, a drive rod 702, a drive gear 703, a follower gear 704, and a tool holder 705. The first motor 701 is mounted on the outer plate 11. The output end of the first motor 701 is connected to the drive rod 702, which is rotatably connected to the outer plate 11. The drive gear 703 is mounted on the end of the drive rod 702. The drive gear 703 meshes with multiple follower gears 704, and each follower gear 704 is connected to a tool holder 705. Each tool holder 705 is rotatably connected to the end plate 12. Multiple cutting tools are mounted on each tool holder 705.

[0028] In practice, the operation of the first motor 701 causes the drive rod 702 to drive the drive gear 703 to rotate, which in turn causes each follower gear 704 to drive the corresponding tool holder 705 to rotate, thereby enabling the tools on each tool holder 705 to work.

[0029] The tool changing mechanism 8 includes a second motor 801, a rotating rod 802, a first gear 803, and a gear sleeve 804. The second motor 801 is mounted on the bracket 2. The output end of the second motor 801 is connected to the rotating rod 802. The first gear 803 is mounted on the end of the rotating rod 802. The first gear 803 is rotatably connected to the gear sleeve 804, which is rotatably mounted on the bracket 2. The gear sleeve 804 has multiple shaft holes, and a tool holder 705 is rotatably connected to each shaft hole.

[0030] In practice, the second motor 801 is operated, causing the rotating rod 802 to rotate, which in turn causes the first gear 803 to mesh with the gear sleeve 804 to rotate. This allows each cutter bar 705 to rotate along with the end plate 12 and the bushing 13, thereby adjusting the material roller 4 to cooperate with the corresponding cutter bar 705, and thus selecting the cutting tool for processing according to the requirements.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
