Description

Technical Field

[0001] The invention belongs to the technical field of cutting dust removal equipment, and in particular relates to an auxiliary device for toothless saw cutting. Background Art

[0002] A toothless saw is an electric tool commonly used in cutting processes. It is used to cut iron wires and pipes. It can also easily cut various mixed materials including steel, copper, aluminum profiles, wood, etc. It can also be used to cut wood, plastic, iron sheets and other objects during emergency rescue.

[0003] Toothless saws are widely used for small-scale cutting of metal materials. They are relatively inexpensive and easy to use. However, when cutting steel, they generate a large amount of sparks and dust. Existing toothless saws generally lack protective measures, resulting in sparks and harmful dust during use. Typically, a cover is used to shield the saws, but this often prevents sawdust from being recovered, is difficult to remove, and requires the cover to be flush with the toothless saw, making it ineffective at blocking sparks. Furthermore, the saws cannot be moved quickly, making them inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary device for toothless saw cutting to solve the problems in the prior art of toothless saws generating sparks when cutting metal materials, posing safety hazards, and the inability to collect the generated debris.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An auxiliary device for cutting with a toothless saw, comprising a side box for collecting sparks and dust generated by cutting, a collection box and guide plates symmetrically arranged on both sides of the collection box, an arc-shaped baffle arranged in the side box facing the toothless saw body, an air compressor installed at the lower end of the arc-shaped baffle, and an air outlet of the air compressor controlling the guide plate to vibrate and guide the material through a transmission mechanism;

[0007] The transmission mechanism includes a fixing seat for installing the air compressor, a cylinder body connected to the air outlet end of the air compressor, an air cavity and an impact cavity are formed in the cylinder body, an upper magnet is attached to the bottom of the air cavity, an impact hammer is movably provided in the impact cavity, a transmission plate for impact transmission with the impact hammer is provided under the impact cavity, a spring for resetting is installed at one end of the impact hammer, and a lower magnet matching the upper magnet is provided at the other end; a flow channel is provided between the lower magnet and the impact hammer, and an air passage is provided in the middle of the impact hammer, and the flow channel, the air cavity and the air passage are connected; the transmission plate is connected to the guide plate to control the up and down vibration of the end of the guide plate.

[0008] As a further optimization scheme of the present invention, the air inlet end of the air compressor is connected to the air pipe arranged at the upper end of the arc-shaped baffle, and the air pipe is provided with an air hole facing the inner side of the arc-shaped baffle.

[0009] As a further optimized solution of the present invention, a limiting frame is provided at the lower end of the cylinder body, a sliding rod is slidably connected in the limiting frame, and the lower end of the sliding rod is fixedly connected to the transmission plate.

[0010] As a further optimized solution of the present invention, the auxiliary device also includes a chassis, which is rotatably connected to the side box and can be stored in the side box, and the chassis is used for movably mounting the toothless saw body.

[0011] As a further optimization scheme of the present invention, the arc-shaped baffle is arranged outside the arc-shaped path of rotation of the base frame, and the space below the arc-shaped baffle and above the guide plate is used to store the merged base frame.

[0012] As a further optimization solution of the present invention, a slide rail is provided on the upper end surface of the chassis, and a mounting frame for mounting the toothless saw body is slidably mounted on the slide rail.

[0013] As a further optimization scheme of the present invention, a slide is provided on the side of the side box, a slider is provided in the slide, a vertical plate is inserted and fixed in the slider, the upper end of the vertical plate extends to the outside of the slide and is connected to the end inclined surface of the transmission plate, and the lower end of the vertical plate is rigidly connected to the end of the guide plate.

[0016] The present invention arranges the base frame to be stored in the side box by rotation, so that the auxiliary device is easy to store. At the same time, an arc-shaped baffle is provided in the side box. By using an air compressor as a power source, its air inlet end draws air to the inside of the arc-shaped baffle through the air pipe and air holes, so that sparks and dust generated by cutting are more convenient to collect under the arc-shaped baffle. At the same time, the air outlet end of the air compressor is connected to the transmission mechanism, so that the impact hammer reciprocates and strikes the transmission plate.

DETAILED DESCRIPTION

[0025] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] Combine Figure 1-7 As shown, a toothless saw cutting auxiliary device includes a side box 1 for collecting sparks and dust generated by cutting. A collection box 11 and material guide plates 10 symmetrically arranged on both sides of the collection box 11 are provided in the side box 1. An arc-shaped baffle 9 is provided in the side box 1 facing the toothless saw body 4. An air compressor 132 is installed at the lower end of the arc-shaped baffle 9. The air outlet of the air compressor 132 controls the material guide plate 10 to vibrate and guide the material through a transmission mechanism 13.

[0028] The transmission mechanism 13 includes a fixing base 131 for mounting an air compressor 132, a cylinder body 133 connected to the air outlet end of the air compressor 132, an air cavity 137 and an impact cavity 134 are formed in the cylinder body 133, an upper magnet 136 is attached below the air cavity 137, an impact hammer 135 is movably provided in the impact cavity 134, a transmission plate 18 for impact transmission with the impact hammer 135 is provided below the impact cavity 134, a spring 139 for resetting is installed at one end of the impact hammer 135, and a lower magnet 138 cooperating with the upper magnet 136 is provided at the other end; a flow channel 17 is provided between the lower magnet 138 and the impact hammer 135, and an air passage is provided in the middle of the impact hammer 135, and the flow channel 17, the air cavity 137 and the air passage are connected; the transmission plate 18 is connected to the guide plate 10 in a transmission manner to control the up and down vibration of the end of the guide plate 10.

[0029] When the toothless saw of the present invention cuts metal materials, sparks and dust will be generated. The arc-shaped baffle 9 can prevent the sparks and dust from flying. The collected dust falls on the guide plate 10. At this time, the air compressor 132 is started. The air compressor 132 discharges the compressed air into the air cavity 137. Since the inner diameter of the flow channel 17 is small, the gas will be compressed in the air cavity 137 and the air pressure will continue to increase. As the compressed air continues to enter the air cavity 137, when the air pressure in the air cavity 137 is greater than the adsorption force between the upper magnet 136 and the lower magnet 138, the compressed air will The impact hammer 135 is pushed to quickly impact the transmission plate 18 provided at the lower end of the cylinder body 133, generating vibration. Subsequently, the gas in the air cavity 137 instantly enters the impact cavity 134, causing the air pressure in the air cavity 137 to drop suddenly. Under the action of the reset force of the spring 139 and the magnetic attraction, the impact hammer 135 quickly resets to complete an impact process. When the impact hammer 135 resets, the upper space of the impact hammer 135 is squeezed, causing the air in the upper space to enter the air cavity 137 along the air channel-flow channel 17, thereby accelerating the reset of the impact hammer 135.

[0030] In the present invention, the air inlet end of the air compressor 132 is connected to the air pipe 12 provided at the upper end of the arc baffle 9, and the air pipe 12 is provided with an air hole 14 facing the inner side of the arc baffle 9. By using the air compressor 132 as a power source, its air inlet end draws air toward the inner side of the arc baffle 9 through the air pipe 12 and the air hole 14, so that the sparks and dust generated by cutting are more easily collected under the arc baffle 9. At the same time, the air outlet end of the air compressor 132 is connected to the transmission mechanism 13, so that the impact hammer 135 reciprocates and strikes the transmission plate 18. Since the transmission plate 18 and the guide plate 10 are connected in transmission, the guide plate 10 can be driven to vibrate reciprocally up and down, thereby preventing the accumulation of sparks and dust on the guide plate 10 and accelerating their collection in the collection box 11.

[0031] It should be noted that in the present invention, an ultra-dense filter is provided in the air hole 14 so that when the air compressor 132 draws air, sparks and dust below the arc-shaped baffle 9 will not enter the air hole 14.

[0032] Combine Figure 4 As shown, a limit frame 15 is provided at the lower end of the cylinder body 133, and a sliding rod 16 is slidably connected in the limit frame 15. The lower end of the sliding rod 16 is fixedly connected to the transmission plate 18, providing a path for the transmission plate 18 to vibrate up and down.

[0033] The auxiliary device in the present invention also includes a base frame 2, which is rotatably connected to the side box 1 and can be stored in the side box 1, and the base frame 2 is used for movably mounting the toothless saw body 4. In the present invention, the lower ends of the side box 1 and the base frame 2 are respectively provided with retractable movable wheels 6 and rollers 6 to facilitate the transfer and use of the auxiliary device; and the handle 8 provided on the side of the side box 1 can open the side door of the side box 1 to facilitate the removal of waste chips collected in the collection box 11 in the side box 1.

[0034] Combine Figure 2 It can be seen that the arc baffle 9 is arranged outside the arc path of rotation of the base frame 2, and the space below the arc baffle 9 and above the guide plate 10 is used to store the merged base frame 2.

[0035] A slide rail 7 is provided on the upper end surface of the base frame 2, and a mounting frame 3 for mounting the toothless saw body 4 is slidably mounted on the slide rail 7, so that the position of the mounting frame 3 on the slide rail 7 can be easily adjusted so that sparks and dust can be collected in the side box 1 as much as possible when the toothless saw body 4 is cutting.

[0036] A slide 19 is provided on the side of the side box 1, and a slider 20 is provided in the slide 19. A vertical plate 21 is inserted and fixed in the slider 20. The upper end of the vertical plate 21 extends to the outside of the slide 19 and is connected to the end inclined surface of the transmission plate 18. The lower end of the vertical plate 21 is rigidly connected to the end of the guide plate 10. A damping spring 22 is provided between the lower side surface of the vertical plate 21 and the bottom inner side of the slide 19.

[0037] Combine Figure 1-7As shown, when the auxiliary device is in use, the air compressor 132 is used as a power source. The air inlet end thereof draws air toward the inner side of the arc-shaped baffle 9 through the air pipe 12 and the air hole 14, so that the sparks and dust generated by cutting are more easily collected under the arc-shaped baffle 9. The compressed air is discharged into the air cavity 137 through the air outlet end of the air compressor 132. Since the inner diameter of the flow channel 17 is small, the gas will be compressed in the air cavity 137 and the air pressure will continue to increase. As the compressed air continues to enter the air cavity 137, when the air pressure in the air cavity 137 is greater than the adsorption force between the upper magnet 136 and the lower magnet 138, the compressed air will push the impact hammer 135 to quickly move toward the transmission provided at the lower end of the cylinder body 133. The plate 18 collides and vibrates. Subsequently, the gas in the air cavity 137 instantly enters the impact cavity 134, causing the air pressure in the air cavity 137 to drop suddenly. Under the action of the reset force of the spring 139 and the magnetic attraction, the impact hammer 135 quickly resets to complete an impact process. When the impact hammer 135 resets, the upper space of the impact hammer 135 is squeezed, causing the air in the upper space to enter the air cavity 137 along the air channel-flow channel 17 to accelerate the reset of the impact hammer 135; and due to the inclined transmission connection between the transmission plate 16 and the vertical plate 17, the guide plate 10 can be driven to vibrate reciprocatingly up and down, preventing sparks and dust from accumulating on the guide plate 10 and accelerating their collection in the collection box 11.

[0038] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
