Description

Technical Field

[0001] This utility model relates to the field of silencer tube production technology, and in particular to a cutting device for sheet metal before silencer tube forming. Background Technology

[0002] A silencer is a noise reduction device used in airflow ducts that simultaneously transmit noise. It utilizes pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area or other discontinuous acoustic impedance to attenuate or reflect noise back into the duct. The former is called a resistive silencer, and the latter a reactive silencer. There are also composite impedance silencers. Before forming, silencers usually need to have through holes evenly opened on the sheet metal, then cut it, and then pre-bend the sheet metal for welding. When cutting the sheet metal, it is usually placed flat on the processing table, the cutting length is measured, and the cutting is carried out directly. This can easily lead to problems such as irregular placement of the sheet metal and cutting deviation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a cutting device for sheet metal before the formation of a silencer pipe, thereby solving the problems mentioned in the background art.

[0004] A cutting device for sheet metal before forming a silencer pipe includes a worktable and a cutting mechanism, a limiting component, and a positioning component mounted on the worktable. The positioning component includes a fixed platform, a pushing part, a connecting plate, a fixed column, an adjusting screw one, an adjusting screw two, a fixed rod two, a mounting plate, rollers, pressure rods, and roller seats. Two fixed platforms are mounted opposite each other on the worktable. Multiple roller seats are fixedly connected to the pushing part through the fixed platforms via fixed shafts. The mounting plate is located below the fixed platforms and is rotatably connected to the two ends of the adjusting screws threaded to one side of the fixed platforms. Multiple rollers are arranged and mounted on the mounting plate. There are two pressure rods, which respectively pass through the ear holes on the upper side of the two pushing parts and slide up and down along the fixed column fixed on the fixed platform. The two ends of the two pressure rods that are close to each other are fixedly connected through the connecting plate. The adjusting screw one is rotatably mounted on the fixed platform and is drivenly connected to a corresponding connecting plate.

[0005] By adopting the above technical solution, it is convenient to limit the material, so that the cutting position can be quickly and accurately placed directly below the laser cutting machine, so that the cutting mechanism can cut it.

[0006] The limiting component includes an electric push rod, a fixed rod, and a baffle. The electric push rod is installed on the workbench, and its output end is fixedly connected to the baffle. Fixed rods are also provided on both sides of the push rod for stable movement of the baffle.

[0007] By adopting the above technical solution, the plate to be cut can be moved to the bottom of the cutting mechanism for cutting.

[0008] An opening is provided on one side of the worktable. The width of the opening is less than the distance between the two fixed tables. A cutting groove is also provided directly below the laser cutting machine output end of the cutting mechanism.

[0009] By adopting the above technical solution, the normal cutting of the board material will not be affected.

[0010] Two fixed platforms have an opening two on one side adjacent to each other. The pushing part is located above the fixed platform and is arranged along the side of the fixed platform where the opening two is located. A support arm is also provided on the pushing part.

[0011] By adopting the above technical solution, it is easier to adjust the position of the control roller of the push unit.

[0012] At least two rollers are provided below the pushing part, respectively distributed on the upper sides of the second opening, and two pressure rods are respectively provided on the upper sides of the second opening.

[0013] By adopting the above technical solution, pressure is applied from above to limit the material, so that the cutting mechanism can cut the material.

[0014] The beneficial effects of the cutting device for the sheet metal before the formation of the silencer pipe in this utility model are: Depending on the required cutting length, first control the electric push rod to move the baffle to the appropriate position. Then, place the pre-drilled sheet material (for the silencer pipe to be made) flat on the worktable surface, ensuring one side of the sheet material is against the baffle. Next, based on the width of the sheet material, rotate the adjusting screw two to push the mounting plate, causing the roller to limit the side of the sheet material. Then, rotate the adjusting screw one to move the connecting plate downwards. The connecting plate simultaneously moves the pressure rod downwards, which in turn moves the pushing part downwards. Since the bottom of the pushing part is fixedly connected to the roller seat via a fixed shaft, the roller seat can then move downwards, applying pressure to the sheet material. Move the sheet material to be cut to directly below the laser cutting output end of the cutting mechanism, and control the cutting mechanism to cut the sheet material. This method facilitates limiting the sheet material, ensuring the cutting position is quickly and accurately placed directly below the laser cutting machine for easy cutting by the cutting mechanism.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] This utility model provides a cutting device, such as a cutting device for a sheet metal before the formation of a silencer pipe.

[0019] Reference Figure 1-3 The system includes a worktable 1 and a cutting mechanism 2, a limiting component 3 and a limiting component 4 mounted on the worktable 1. The limiting assembly 4 includes a fixed platform 401, a pushing part 402, a connecting plate 404, a fixing column 405, an adjusting screw 1 406, an adjusting screw 2 407, a fixing rod 2 408, a mounting plate 409, a roller 410, a pressure rod 411, and roller seats 412. The fixed platforms 401 are two oppositely mounted on the worktable 1. The roller seats 412 are multiple roller seats that are fixedly connected to the pushing part 402 through the fixed platforms 401 via fixed shafts. The mounting plate 409 is located below the fixed platforms 401 and is threadedly connected to them. The adjusting screw 407 on one side of the fixed platform 401 is rotatably connected to the end. Multiple rollers 410 are arranged and installed on the mounting plate 409. There are two pressure rods 411, which respectively pass through the ear holes on the upper side of the two push parts 402 and slide up and down along the fixed column 405 fixed on the fixed platform 401. The two ends of the two pressure rods 411 that are close to each other are fixedly connected by the connecting plate 404. The adjusting screw 406 is rotatably installed on the fixed platform 401 and is connected to the corresponding connecting plate 404. Reference Figure 1The cutting mechanism 2 includes a horizontal drive assembly, a vertical drive assembly, and a laser cutter. The horizontal drive assembly includes a motor, a lead screw, a guide rail, and a slide. The motor controls the lead screw to move the slide laterally along the guide rail. The vertical drive assembly is mounted on the horizontal drive assembly. The vertical drive assembly also includes a motor, a lead screw, a guide rail, and a slide. The motor controls the lead screw to move the slide longitudinally along the guide rail. The laser cutter is mounted on the slide of the vertical drive assembly. After the sheet material is placed, the horizontal drive assembly can be controlled to move the vertical drive assembly laterally. Then, the vertical drive assembly moves the laser cutter downward to the appropriate position, and the laser cutter is started to cut the sheet material.

[0020] Two fixed platforms 401 have an opening 4011 on one side adjacent to each other. A pushing part 402 is located above the fixed platform 401. Its structure is arranged along the side of the fixed platform 401 where the opening 401 is located. A support arm 403 is also provided on the pushing part 402. The opening 4011 will not affect the normal movement and cutting of the plate by the laser cutting machine of the cutting mechanism 2. Of course, in order to stabilize the position of the plate to be cut, at least two rollers 412 are provided below the pushing part 402, respectively distributed on the upper two sides of the opening 4011. Two pressure rods 411 are respectively provided on the upper two sides of the opening 4011. In this embodiment, three rollers 412 are provided, but at least rollers 412 must be provided on the upper two sides near the opening 4011 to restrict the two sides of the plate to be cut.

[0021] Reference Figure 1 The limiting component 3 includes an electric push rod 301, a fixing rod 302, and a baffle 303. The electric push rod 301 is installed on the workbench 1, and its output end is fixedly connected to the baffle 303. The fixing rod 302 is also provided on both sides of the push rod 301 for stable movement of the baffle 303. The position of the baffle 303 can be adjusted according to the length of the material to be cut.

[0022] In this embodiment, in order to facilitate the movement of the worktable, an opening 101 is provided on one side of the worktable 1. The width of the opening 101 is smaller than the distance between the two fixed tables 401. A cutting groove 102 is also provided directly below the laser cutting machine output end of the cutting mechanism 2. The worker can move to the opening 101 and push the worktable to move it to the cutting groove 102 to wait for cutting.

[0023] The implementation principle of the cutting device for the sheet metal before the formation of the silencer tube in this embodiment of the application is as follows: According to the required cutting length, first control the electric push rod 301 to push the baffle 303 to a suitable position. Then, place the plate with holes drilled for the silencer pipe to be made flat on the upper surface of the workbench 1, so that one side of the plate is attached to the baffle 303. Then, according to the width of the plate, rotate the adjusting screw 407 to push the mounting plate 409, so that the roller 410 limits the side of the plate. Then, rotate the adjusting screw 406 to drive the connecting plate 404 to move downward. The connecting plate 404 simultaneously drives the pressure rod 411 to move downward. In turn, the pressure rod 411 can make the pushing part 402 move downward. Since the bottom surface of the pushing part 402 is fixedly connected to the roller 412 through the fixed shaft, the roller 412 can move downward to apply pressure to the plate. Move the plate to be cut to directly below the laser cutting output end of the cutting mechanism 2, and control the cutting mechanism 2 to cut the plate.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
