Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1 to 6 shown, a cutting device for processing automobile chassis accessories according to the present invention includes a workbench 1, a support assembly, a cutting assembly and a conveying assembly; The conveying assembly is used to convey the pipe fitting 5 to the support assembly after the pipe fitting 5 is cut; the conveying assembly includes a positioning cylinder 2, and the pipe fitting 5 passes through the inside of the positioning cylinder 2; a plurality of groups of guide wheels 3 are evenly distributed on the side wall of the positioning cylinder 2; a conveying wheel 4 is rotatably connected to the bottom of the positioning cylinder 2; the guide wheels 3 and the conveying wheel 4 are both in contact with the pipe fitting 5; The conveying wheel 4 is controlled to rotate by a driving mechanism; the driving mechanism includes a motor 6, a first sheave 7, a transmission belt 8 and a second sheave 9; the transmission belt 8 is sleeved on the surfaces of the first sheave 7 and the second sheave 9; the motor 6 is coaxially connected to the first sheave 7, and the second sheave 9 is coaxially connected to the conveying wheel 4.

[0025] In the prior art, when segmenting and cutting a long pipe fitting 5, it is usually necessary to cut it section by section in sequence. After each section of the pipe fitting 5 is cut, it is necessary to manually take away the cut part and push the uncut part back into the cutting device again. The process is rather cumbersome, overly dependent on manual labor, with low automation and a certain degree of danger.

[0026] When the present invention is in use, the long pipe fitting 5 is pre-inserted into the conveying assembly and the supporting assembly, and then the pipe fitting 5 is cut by the cutting assembly. After each finished short pipe fitting 5 is cut, the conveying wheel 4 is controlled to rotate by the driving mechanism, and the pipe fitting 5 is driven to move inside the positioning cylinder 2 by the frictional force between the conveying wheel 4 and the pipe fitting 5 until the uncut part of the pipe fitting 5 enters the supporting assembly and reaches the specified length, and then the cutting assembly continues to cut. By repeating the above operations in sequence, the cutting work of the pipe fitting 5 can be completed section by section, realizing automatic forward feeding, reducing the labor intensity of relevant personnel. In addition, each time the pipe fitting 5 is conveyed forward, the finished short pipe fitting 5 that has been cut inside the supporting assembly will be pushed outwards, so that it is automatically separated from the cutting equipment, realizing efficient unloading and further improving the working efficiency of the cutting equipment.

[0027] The supporting assembly includes a supporting seat 10; a groove 11 and a positioning hole 12 are formed inside the supporting seat 10, and the pipe fitting 5 passes through the positioning hole 12; a "hui"-shaped receiving groove 13 is formed around the groove 11 at the top of the supporting seat 10; The cutting assembly includes a lifting seat 14; a cylinder 15 is fixedly connected between the lifting seat 14 and the workbench 1; an isolation cover 16 is fixedly connected to the lower side of the lifting seat 14; a rotary blade 17 is arranged inside the isolation cover 16.

[0028] Each time the conveying assembly pushes the material, after the pipe fitting 5 is inserted into the supporting seat 10 along the positioning hole 12 and reaches the specified length, the lifting seat 14 is controlled to move downward by the cylinder 15, and the pipe fitting 5 is cut by the rotary blade 17. At the same time, the isolation cover 16 is buckled downward on the top of the supporting seat 10 and enters the receiving groove 13, so that a closed space isolated from the outside is formed between the isolation cover 16 and the groove 11, thereby isolating the high-temperature flue gas and metal chips generated during the cutting process inside the closed space and preventing them from leaking outwards, so as to prevent pollution to the surrounding working environment.

[0029] As a preferred embodiment of the present invention, the rotary blade 17 includes a grinding layer 171 and a cutting layer 172; the cutting layer 172 is located at the outer edge of the grinding layer 171; the grinding layer 171 has a rough surface, and its material can be ceramic, resin or others. During the downward movement of the rotary blade 17, the cutting layer 172 first contacts the pipe fitting 5 and gradually cuts it off, and then the grinding layer 171 contacts the cross section of the pipe fitting 5 and grinds it, reducing the burrs and debris generated by cutting and improving the flatness of the cross section of the pipe fitting 5, which is beneficial to the subsequent welding operation.

[0030] As a preferred embodiment of the present invention, a pressing plate 18 is slidably connected inside the storage groove 13; a gas storage block 19 is arranged between the pressing plate 18 and the bottom of the storage groove 13; an annular groove 20 is formed in the inner wall of the positioning hole 12; an air vent ring 21 is fixedly connected inside the annular groove 20; both the gas storage block 19 and the air vent ring 21 are elastic and communicate with each other. The diameter of the positioning hole 12 should be slightly larger than the diameter of the pipe fitting 5 to facilitate the insertion of the pipe fitting 5 into the positioning hole 12 and its movement inside the positioning hole 12. When the bottom of the isolation cover 16 is buckled into the storage groove 13, it can drive the pressing plate 18 to move downward, squeezing the gas storage block 19 by the pressing plate 18, and squeezing the gas inside the gas storage block 19 into the air vent ring 21, causing the air vent ring 21 to inflate and fit tightly with the pipe fitting 5. On the one hand, it can press and fix the pipe fitting 5, improving the stability during the cutting of the pipe fitting 5. On the other hand, using the inflated air vent ring 21 to fill the gap between the pipe fitting 5 and the positioning hole 12 can improve the sealing performance here and prevent the contaminated flue gas generated during the cutting process from flowing out through this gap.

[0031] As a preferred embodiment of the present invention, a storage chamber 22 is arranged at one side of the groove 11 at the bottom of the support base 10; an inclined support 23 is fixedly connected to the bottom of the groove 11; a slag guiding channel 24 is formed between the inclined support 23 and the storage chamber 22.

[0032] A processing chamber 25 is arranged at the other side of the groove 11 at the bottom of the support base 10; an air guiding channel 26 is formed between the processing chamber 25 and the groove 11; a filter screen 27 is arranged inside the air guiding channel 26; the processing chamber 25 is communicated with an external connecting pipe 28, and the external connecting pipe 28 is connected to an external negative pressure device; a hollow sleeve 29 is fixedly connected to the top of the processing chamber 25; water is added to the bottom of the processing chamber 25, and the hollow sleeve 29 is communicated with a water pump 31 through a water delivery pipe 30; a group of guide holes 32 are evenly distributed on the lower side of the hollow sleeve 29.

[0033] During cutting, the metal chips generated fall along the inclined support 23 at the bottom of the groove 11 and the slag guiding channel 24 into the storage chamber 22 for collection and storage. A clean-out opening that can be opened and closed should be arranged on one side of the support base 10 to take out the metal chips inside when the storage chamber 22 is full. And during cutting, the processing chamber 25 is sucked by an external negative pressure device, so that the generated high-temperature flue gas is sucked into the processing chamber 25 through the air guiding channel 26. The water pump 31 continuously supplies the water at the bottom of the processing chamber 25 into the hollow sleeve 29 through the water delivery pipe 30, and then the water drips downward through the plurality of guide holes 32, thereby cooling and removing impurities from the flue gas passing through the processing chamber 25, absorbing the contaminated components inside, and further reducing the pollution degree during emission.

[0034] As a preferred embodiment of the present invention, a group of first baffles 33 and second baffles 34 are evenly distributed on the lower side of the hollow sleeve 29; the first baffles 33 and the second baffles 34 are staggered; there is a gap between the bottom of the first baffles 33 and the water surface; a through groove 35 is formed at the top of the second baffles 34. By arranging the first baffles 33 and the second baffles 34 at intervals, an "S"-shaped bending channel can be formed inside the processing chamber 25, so that when the flue gas flows inside the bending channel, the movement path and movement time can be extended, so that the water droplets can fully capture the harmful components in the flue gas and improve the treatment efficiency of pollutants.

[0035] As a preferred embodiment of the present invention, a chute 36 is formed between the diagonal brace 23 and the support base 10; an electromagnet 37 is fixedly connected inside the chute 36; a diagonal block 38 is slidably connected inside the chute 36, and the diagonal block 38 is flush with the surface of the diagonal brace 23; a spring is fixedly connected between the diagonal block 38 and the electromagnet 37; a first magnetic block 39 is embedded on the surface of the diagonal block 38; when the electromagnet 37 is energized, it repels the first magnetic block 39.

[0036] A flexible sealing film 40 is fixedly connected to the connection part between the diagonal block 38 and the diagonal brace 23.

[0037] During the cutting process, the electromagnet 37 is controlled to be continuously energized and de-energized intermittently, and cooperate with the spring, so that the diagonal block 38 continuously moves towards the slag guiding channel 24, thereby pushing the metal chips collected at the bottom of the groove 11 into the storage chamber 22, improving the collection efficiency of the metal chips, preventing the metal chips at the bottom of the groove 11 from gradually accumulating and increasing to cause blockage. When the diagonal block 38 moves out of the chute 36, the flexible sealing film 40 can be stretched and deformed, and the flexible sealing film 40 is used to block the gap between the diagonal block 38 and the diagonal brace 23 to prevent the metal chips from entering the gap.

[0038] As a preferred embodiment of the present invention, a wire mesh cover 41 is fixedly connected to the inner wall of the processing chamber 25 at a position corresponding to the sliding groove 36. Half of the wire mesh cover 41 is above the water surface, and the other half is below the water surface; an elastic pad 42 is fixedly connected to the inner side of the wire mesh cover 41; a porous water-absorbing member 43 is fixedly connected between the wire mesh cover 41 and the elastic pad 42. The material of the porous water-absorbing member 43 can be sponge, rubber foam, silicone foam, etc.; a push block 44 is slidably connected inside the sliding groove 36; a spring is fixedly connected between the push block 44 and the electromagnet 37; a second magnetic block 45 is embedded on the surface of the push block 44; when the electromagnet 37 is energized, it repels the second magnetic block 45. During the process of the electromagnet 37 being energized and de-energized, it cooperates with the spring to control the push block 44 to continuously reciprocate inside the sliding groove 36. When the push block 44 moves towards the wire mesh cover 41, the elastic pad 42 can be used to squeeze the porous water-absorbing member 43, and the water inside the porous water-absorbing member 43 is extruded outwards through the wire mesh cover 41. By using the fine hole structure of the porous water-absorbing member 43, the extruded water can produce an atomization effect, enabling the water mist to fully disperse inside the curved channel near the wire mesh cover 41. Then, when the flue gas passes through this place, the contact uniformity between the flue gas and the water mist can be enhanced, and the treatment efficiency and absorption degree of harmful components in the flue gas can be improved. When the push block 44 moves towards the electromagnet 37, the porous water-absorbing member 43 expands and restores, and its bottom absorbs water through the wire mesh cover 41, and the water gradually redisperses inside the entire porous water-absorbing member 43.
