Description

Technical Field

[0001] This utility model relates to the field of scrap steel extrusion and cutting technology, and in particular to a scrap steel extrusion and cutting device. Background Technology

[0002] The scrap steel extrusion and cutting device is a piece of equipment that integrates mechanical, hydraulic and electrical control technologies. It is mainly used to recycle scrap steel, such as steel from scrapped cars and construction waste, and scrap machinery and equipment. It applies huge extrusion pressure to make the scrap steel plastically deform under pressure, and then uses a cutting mechanism to cut it into scrap steel blocks of specified length or shape.

[0003] In existing technology, excessive internal pressure during extrusion of extrusion components can cause waste material to burst out. If protective measures are inadequate, this can lead to injuries such as pinching or scratching of operators. Therefore, existing technology uses steel plates or wire mesh to completely enclose the danger zone and installs an infrared light curtain in the danger zone. When a person blocks the light curtain, it triggers a shutdown. However, such improvements may have the risk of false alarms due to dust obstruction of fiber optic sensors or failure due to penetration by transparent objects. Moreover, the fully enclosed protective cover makes it inconvenient to transport the scrap steel to be extruded and will also affect equipment observation and subsequent maintenance, reducing work efficiency.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 3 , Figure 5 and Figure 6This utility model provides an embodiment of a scrap steel extrusion and cutting device, including a fixed frame 1. A sealing mechanism 2 is installed on the middle right side of the fixed frame 1. The sealing mechanism 2 is used for sealing before the extrusion operation. A dust collection mechanism 3 is installed on the lower right side of the fixed frame 1. The dust collection mechanism 3 is used for dust collection after the extrusion operation to reduce pollution. The sealing mechanism 2 includes a slider 201. Multiple sliders 201 are respectively installed on the front and rear sides of the middle right side of the fixed frame 1. Baffles 204 are fixedly connected to the front and rear ends of sliders 201. Slide rods 203 are fixedly connected to the front and rear sides of sliders 201. A sliding groove rod 202 is slidably connected to the outer side of slide rods 203. Slider 206 is fixedly connected to the front and rear sides of the bottom left side of baffles 204. Slide rod 207 is slidably connected to the left side of slider 206. A limit block 205 is fixedly connected to the top of the slide bar 207. A drive assembly 208 is installed on the upper right side of the fixed frame 1. The drive assembly 208 includes a motor 2081. The motor 2081 is installed on the upper right rear side of the fixed frame 1. A pulley 2082 is fixedly connected to the output end of the motor 2081. A fixing block 2083 is fixedly connected to the upper left side of the pulley 2082. A long rod 2084 is slidably connected to the inner end of the pulley 2082. A fixing plate 2085 is fixedly connected to the left side of the motor 2081. Fixing plates 2086 are fixedly connected to the front and rear ends of the long rod 2084. A base 3 9 is provided on the lower left side of the fixed frame 1. An electric push rod 10 is fixedly connected to the top of the base 3 9. A top plate 21 is fixedly connected to the right end of the electric push rod 10.

[0034] Specifically, the scrap steel to be processed is placed in the fixed frame 1, and the motor 2081 is started. The output shaft of the motor 2081 drives the pulley 2082 to rotate, causing the slide rod 203 to move up and down. The slide rod 203 is connected to the slider 201, and the slider 201 is connected to the fixed block 2083. Therefore, when the slide rod 203 moves up and down, it will drive the slider 201 and the fixed block 2083 to move synchronously, thereby causing the baffle 204 connected to the fixed block 2083 to move up and down. When the pressure plate 16 presses down, the baffle 204 moves up and down. 04. To achieve a good squeezing effect, as the baffle 204 moves downward, it will drive the slider 206 to move downward along the slide rod 207. The slide rod 207 provides guidance for the movement of the baffle 204, ensuring that the baffle 204 can move smoothly along the path. The limiting block 205 is installed on the slide rod 207. When the slider 206 moves to the limit position, the limiting block 205 will block the slider 206 to prevent it from sliding off the slide rod 207, ensuring the safe operation of the equipment. One end of the long rod 2084 is connected to the fixed plate. The second end of the motor 2086 connects to the pulley 2082, providing support at the other end to ensure the pulley 2082 remains stable during rotation. After the scrap steel is extruded and shaped within the fixed frame 1, the electric push rod 10 is activated. The electric push rod 10 pushes the top plate 21 forward, pushing the extruded scrap steel onto the roller 22. The roller 22 transports the scrap steel to the designated position. The hydraulic cylinder 5 is then activated, driving the cutter 23 to move linearly, cutting the extruded scrap steel to form the desired shape. During the extrusion process, the motor 20 drives the hydraulic cylinder 2086. Pump 17 operates, drawing oil from oil tank 18 and delivering it to manual valve 11 via oil pipe 12. The operator controls the flow direction and flow rate of the oil via manual valve 11. The oil is then delivered to hydraulic cylinder 15 via hydraulic pipe 14, pushing hydraulic cylinder 15 to move pressure plate 16 downwards, squeezing the scrap steel in the fixed frame 1 to complete the squeezing work. After the squeezing work is completed, the equipment can be easily moved to the next working position via wheels 8 installed under the fixed frame 1, providing convenience for subsequent work.

[0035] Reference Figure 1 , Figure 2 and Figure 7The vacuuming mechanism 3 includes a base 301, which is located on the front right side of the fixed frame 1. A vacuum box 302 is installed on the top of the base 301. A suction pipe 303 passes through the lower right side of the vacuum box 302. A soundproof cover 304 is installed on the lower right side of the fixed frame 1. A fixing plate 305 is fixedly connected to the four corners of the outer end of the soundproof cover 304. A nut 307 is threadedly connected to the middle of the fixing plate 305. A bolt 306 is threadedly connected to the outer side of the nut 307. A base 6 is located at the right end of the fixed frame 1. Multiple rollers 22 are equidistantly rotatably connected to the front and rear ends of the left side of the base 6. A bracket 4 is fixedly connected to the top of the base 6. A hydraulic cylinder 5 is fixedly connected to the middle of the top of the bracket 4. A cutter 23 is fixedly connected to the end of the hydraulic cylinder 5. Limit grooves 13 are fixedly connected to the front and rear ends of the middle of the bracket 4.

[0036] Specifically, when the extruded scrap steel is conveyed to roller 22, dust pollutants and noise are generated during the operation of the equipment. To ensure the safety of the working environment, a soundproof cover 304 is provided, which can effectively block the diffusion of dust pollutants and reduce the noise generated by the equipment operation. The soundproof cover 304 is fixed to the base 6 by fixing plate 305, nut 307 and bolt 306. The soundproof cover 304 is kept stable by tightening nut 307. A dust removal system consisting of dust collection box 302 and suction pipe 303 is installed on the side of the soundproof cover 304. The suction pipe 303 is aimed at the inside of the soundproof cover 304 and can remove dust pollutants inside the soundproof cover 304 in real time. With the sealing structure of the soundproof cover 304, the occupational health hazards of dust and noise to operators are effectively reduced, and the pollution of the production environment is reduced.

[0037] Reference Figure 4 Fixed posts 7 are fixedly connected to the four corners of the bottom of the fixed frame 1. Wheels 8 are installed at the ends of the fixed posts 7. Base 4 19 is fixedly connected to the middle of the rear side of the fixed frame 1. Oil tank 18 is fixedly connected to the top of base 4 19. Motor 20 is fixedly connected to the top of base 4 19. Oil pump 17 is fixedly connected to one end of motor 20. Oil pipe 12 is fixedly connected to the other end of motor 20. Manual valve 11 is installed in the middle of the left side of the front end of the fixed frame 1. Oil pipe 12 passes through the right side of manual valve 11. Hydraulic pipe 14 passes through the front end of manual valve 11. Hydraulic cylinder 2 15 passes through the rear end of hydraulic pipe 14. Pressure plate 16 is fixedly connected to the end of hydraulic cylinder 2 15.

[0038] Specifically, the bottom of the fixed frame 1 has fixed columns 7, forming a stable support structure. Each fixed column 7 has wheels 8 underneath, which facilitates the movement and positioning of the equipment. The base 19 provides support for the oil tank 18 and the motor 20. The oil tank 18 is used to store the oil required by the hydraulic system. One end of the motor 20 is connected to the oil pump 17, and the other end is connected to the oil pipe 12. When the motor 20 is working, it drives the oil pump 17 to run, and transports the oil in the oil tank 18 to the hydraulic system through the oil pipe 12. A manual valve 11 is installed in the middle of the left front side of the fixed frame 1. The manual valve 11 is used to control the flow direction and flow rate of the oil. The oil enters the manual valve 11 through the oil pipe 12, and then is transported to the hydraulic cylinder 15 through the hydraulic pipe 14. The hydraulic cylinder 15 pushes the pressure plate 16 to make linear motion, realizing the squeezing operation of the scrap steel in the fixed frame 1.

[0039] Working Principle: During scrap steel processing, the scrap steel to be processed is first placed in the fixed frame 1. Motor 2081 is started, driving pulley 2082 to rotate. Pulley 2082 transmits power to slide rod 203, causing slide rod 203 to move up and down. Slide rod 203 is connected to slider 201, which in turn is connected to fixed block 2083. Therefore, when slide rod 203 moves up and down, it drives slider 201 and fixed block 2083 to move synchronously, thereby causing baffle 20 connected to fixed block 2083 to move synchronously. 4. The device moves vertically, so that when the pressure plate 16 presses downwards, the baffle 204 works in tandem to create a good pressing effect. During its downward movement, the baffle 204 drives the slider 206 to move downwards along the slide rod 207. The slide rod 207 guides the movement of the baffle 204, ensuring it moves smoothly along the path. A limiting block 205 is mounted on the slide rod 207. When the slider 206 reaches its limit position, the limiting block 205 blocks it, preventing it from sliding off the slide rod 207 and ensuring the equipment's stability. For safe operation, one end of the long rod 2084 is connected to the fixed plate 2086, and the other end provides support for the pulley 2082, ensuring the pulley 2082 remains stable during rotation and can operate normally. After the scrap steel is extruded and shaped in the fixed frame 1, the electric push rod 10 is activated. The electric push rod 10 pushes the top plate 21 forward, pushing the extruded scrap steel onto the roller 22 and transporting the scrap steel to the designated position. At this time, the hydraulic cylinder 5 is activated, and the hydraulic cylinder 5 drives the cutter 23 to move linearly, cutting the extruded scrap steel to form the desired shape. During the extrusion process, the oil pump 17 is driven by the motor 20. The oil pump 17 draws oil from the oil tank 18 and delivers the oil to the manual valve 11 through the oil pipe 12. The oil is then delivered to the hydraulic cylinder 15 through the hydraulic pipe 14. The oil forms pressure in the hydraulic cylinder 15, which pushes the hydraulic cylinder 15 to move the pressure plate 16 downward, extruding the scrap steel in the fixed frame 1 to complete the extrusion work. After the extrusion work is completed, the equipment can be easily moved to the next working position through the wheels 8 installed under the fixed frame 1, providing convenience for subsequent work.

[0040] When the scrap steel that has completed the extrusion process is conveyed onto the roller 22, a large amount of dust and pollutants are generated. At the same time, the equipment also generates noise during operation. In order to reduce the harm of these pollutants and noise to the workers, a soundproof cover 304 is installed at the corresponding position of the equipment. This can effectively isolate the spread of dust and pollutants, and also play a certain role in isolating the noise generated by the operation of the equipment. The soundproof cover 304 is fixed to the base 6 by fixing plate 305, nut 307 and bolt 306 to ensure its stability. There is a dust collection box 302 and a suction pipe 303 on the side of the soundproof cover 304. The dust and pollutants inside the soundproof cover 304 are sucked into the dust collection box 302 for collection and treatment through the suction pipe 303, thereby reducing the harm to the workers and the pollution to the environment.
