Description

Technical Field

[0001] The present invention relates to the field of bar processing, and particularly to a straightening device for processing metal bars. Background Art

[0002] A straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine extrudes bars and the like through straightening rollers to change their straightness. Generally, there are two rows of straightening rollers with different numbers, and there are also two-roller straightening machines. The main types include pressure straightening machines, balance roll straightening machines, shoe roll straightening machines, rotary reverse bending straightening machines, etc.

[0003] When the existing device processes metal bars, it mostly extrudes the bars and the like through straightening rollers to change their straightness. The straightening rollers extrude the bars. When the bars are bent greatly, a large extrusion force may be applied to the outer surface of the bars during straightening, causing deformation of the outer surface of the bars. It is not easy to detect in time during the straightening work and subsequent inspection of the bar surface is required, which not only affects the working efficiency of the device but also increases the time for later manual inspection. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: A straightening device for processing metal bars according to the present invention includes a main body housing. A leg is fixedly connected to the bottom of the outer surface of the main body housing. A baffle is slidably connected to the middle of the inner cavity of the main body housing. The bottom of the outer surface of the baffle is slidably connected to the bottom of the inner cavity of the main body housing. A grinding component is fixedly connected to one side of the inner cavity of the main body housing. A guiding component is fixedly connected to one side of the inner cavity of the main body housing near the baffle. A cleaning component is fixedly connected to the outer surface of the main body housing away from the grinding component. A detecting component is fixedly connected to one end of the outer surface of the baffle away from the main body housing. A sliding rod is rotatably connected to the inner cavity of the main body housing. The sliding rod penetrates the inner wall of the baffle, and the outer surface of the sliding rod is slidably connected to the inner wall of the baffle. A threaded rod is threadedly connected to the middle of the inner cavity of the main body housing. The threaded rod penetrates the inner wall of the baffle, and the outer surface of the threaded rod is threadedly connected to the inner wall of the baffle. A straightening roller is fixedly connected to the top of the outer surface of the baffle. During operation, by rotating the threaded rod, the threaded rod rotates in the inner cavity of the main body housing, so that the threaded rod drives the two baffles to move relatively, thereby adjusting the size of the straightening spacing according to the size of different bars, so that the straightening roller straightens the bars.

[0005] Preferably, the detection component includes a detection shaft. A detection block is fixedly connected to one end of the outer surface of the detection shaft away from the baffle. A detection spring is sleeved on the outer surface of the detection shaft. A fixing rod is fixedly connected to the middle of the end of the outer surface of the detection block close to the detection shaft. An induction plug is fixedly connected to the end of the fixing rod away from the detection block. An induction socket is fixedly connected to the middle of the end of the baffle close to the detection shaft. During the straightening process of the bar, through the stretching action of the detection spring, the detection block abuts against the bar during processing, so as to detect the outer surface of the bar. When the outer surface of the bar is damaged and a drop outside the error range occurs, the induction plug abuts against the induction socket, so that the detection component issues an alarm, thus reminding the operator. By setting the detection component in the present invention, when the bar is straightened, the straightening roller squeezes the bar. When the bar is bent greatly, a large extrusion force may be applied to the outer surface of the bar during straightening, causing the outer surface of the bar to deform. It is not easy to detect in time during the straightening work and subsequent inspection of the bar surface is required. By adding the detection component, the surface of the bar can be detected in time after the bar straightening operation, avoiding the time of subsequent manual detection and improving the working efficiency of the device.

[0006] Preferably, the grinding component includes a grinding plate. A grinding block is fixedly connected to the top of the outer surface of the grinding plate. A connecting rod is fixedly connected to the top of the outer surface of the grinding plate. The end of the connecting rod away from the grinding plate is slidably connected to a clamping plate. A grinding spring is sleeved on the outer surface of the connecting rod. The end of the grinding spring close to the grinding plate is fixedly connected to the top of the outer surface of the grinding plate. The end of the grinding spring away from the grinding plate is fixedly connected to the bottom of the outer surface of the clamping plate. A filter screen plate is fixedly connected to the middle of the inner cavity of the main body housing. A motor is fixedly connected to the bottom of the outer surface of the main body housing. A fan blade is fixedly connected to the outer surface of the output end of the motor. A pulley is rotatably connected to the side of the bottom of the outer surface of the main body housing away from the motor. A grinding belt is rollingly connected to the middle of the outer surface of the pulley. The end of the outer surface of the grinding belt away from the pulley is rollingly connected to the middle of the outer surface of the output end of the motor; during operation, the bar to be processed is placed into the grinding component. By pulling the clamping plate, the bar to be processed is fixed. While the bar moves, the burrs on the bar are removed and ground by the grinding block on the grinding plate. At the same time, by turning on the motor, the fan blade is driven to rotate in the inner cavity of the main body housing. At the same time, the rotation of the output end of the motor drives the grinding belt to rotate. Through the transmission of the grinding belt, the pulley drives the fan blade to rotate, so that the waste chips generated during grinding are adsorbed on the filter screen plate by the rotation of the fan blade. By setting the grinding component in the present invention, when straightening the bar, there are a large number of burrs on the surface of the bar. If the surface of the bar is not ground during the straightening work, the residual burrs on the surface of the bar will cause accidental injury to the surface of the bar when the straightening roller is in pressing contact with the bar during the straightening work, affecting the flatness of the surface of the bar. By adding the grinding component, the surface of the bar is ground before the bar is straightened, avoiding accidental injury caused by subsequent work.

[0007] Preferably, the guiding component includes a guiding shaft, the outer surface of the guiding shaft is fixedly connected to the bottom of the inner cavity of the main body housing, the top of the outer surface of the guiding shaft is slidably connected with a guiding plate, a roller shaft is rotatably connected to the inner cavity of the guiding plate, a chute is provided on the outer surface of the guiding shaft, the inner cavity of the chute is rotatably connected with a large connecting rod through a socket, one end of the large connecting rod away from the chute is rotatably connected with a slider, one end of the outer surface of the slider close to the guiding plate is slidably connected with the outer surface of the guiding plate, a resisting block is fixedly connected to the end of the outer surface of the slider away from the guiding plate, a guiding spring is fixedly connected to the bottom of the inner cavity of the chute, and one end of the guiding spring away from the bottom of the inner cavity of the chute is fixedly connected to the end of the large connecting rod away from the slider; when the bar passes through the guiding component, the weight of the bar itself causes the guiding plate to slide on the guiding shaft, so that the large connecting rod slides in the inner cavity of the chute through the socket, and then drives the slider to slide on the outer surface of the guiding plate through the pulling of the large connecting rod, driving the resisting block to limit the bar on the guiding component. Through the continuous movement of the bar, the bar continuously slides through the roller shaft in the inner cavity of the guiding plate. By setting the guiding component in the present invention, before the bar stock is corrected, the device is adjusted in size according to bars of different sizes, so that the device can perform correction processing operations on different bars. After the adjustment is completed, the pipe material removes burrs through the grinding component and then is corrected through the guiding component, preventing the bar from shifting during the correction work, so that the bar breaks during the correction work, affecting the subsequent correction work.

[0008] Preferably, the cleaning component includes a cleaning plate. A cleaning frame is slidably connected to the top of the outer surface of the cleaning plate. A plurality of cleaning rollers are evenly arranged in the inner cavity of the cleaning frame. The middle of the outer surface of the cleaning frame is rotatably connected to a small connecting rod through a socket. One end of the small connecting rod away from the cleaning frame is rotatably connected to a guiding block through a socket. A plurality of friction blocks are evenly arranged on the top of the outer surface of the guiding block. The middle of the outer surface of the guiding block is slidably connected to a connecting shaft. One end of the connecting shaft away from the guiding block is fixedly connected to the inner wall of the main body housing. A cleaning spring is sleeved on the outer surface of the connecting shaft. One end of the cleaning spring close to the guiding block is fixedly connected to the outer surface of the guiding block. One end of the cleaning spring away from the guiding block is fixedly connected to the inner wall of the main body housing; after the bar stock completes the straightening work and reaches the cleaning component through the guiding component, due to the continuous movement of the bar stock, it abuts against the guiding block. Through the frictional force generated between the bar stock and the friction blocks, the guiding block is driven to move upward along the connecting shaft. While the guiding block moves, it pulls the small connecting rod to move, so that the small connecting rod drives the cleaning frame to move on the cleaning plate, thereby enabling the cleaning rollers in the inner cavity of the cleaning frame to clean the surface of the processed bar stock. By setting the cleaning component in the present invention, after the bar stock finishes the straightening work, when the bar stock is being straightened, waste chips extruded and shed will remain on the surface. When the worker stores the bar stock, the shed chips will prick the worker's palm, and at the same time, it is not convenient for the subsequent collection work of the bar stock. By adding the cleaning component, the surface of the bar stock can be cleaned while the bar stock is moving and being conveyed, avoiding the cumbersome subsequent manual cleaning and improving the working efficiency of the device.

[0009] The beneficial effects of the present invention are as follows: 1. By setting the grinding component in the present invention, when straightening the bar stock, there are a large number of burrs on the surface of the bar stock. If the surface of the bar stock is not ground during the straightening work, when the straightening work is carried out, the remaining burrs on the surface of the bar stock will cause accidental damage to the surface of the bar stock when the straightening roller is in extrusion contact with the bar stock, affecting the flatness of the surface of the bar stock. By adding the grinding component, the surface of the bar stock is ground before the straightening work is carried out, avoiding accidental damage caused by subsequent work.

[0010] 2. By setting the detection component in the present invention, when the bar stock is being straightened, the straightening roller exerts extrusion on the bar stock. When the bar stock is bent greatly, a large extrusion force may be exerted on the outer surface of the bar stock during straightening, causing the outer surface of the bar stock to deform. It is not easy to detect in time during the straightening work, and subsequent inspection of the surface of the bar stock is required. By adding the detection component, the surface of the bar stock can be detected in time after the bar stock is straightened, avoiding the time of subsequent manual detection and improving the working efficiency of the device.

[0011] 3. By providing a guiding component, before the bar stock is straightened, the device is adjusted in size according to bar stocks of different sizes, enabling the device to perform straightening processing operations on different bars. After the adjustment is completed, the pipe is deburred by the grinding component and then straightened through the guiding component, preventing the bar from shifting during the straightening process and thus avoiding breakage of the bar during the straightening process, which may affect the subsequent straightening work.

[0012] 4. By providing a cleaning component, after the bar stock is straightened, during the straightening process of the bar stock, waste chips squeezed and shed will remain on the surface. When workers store the bar stock, the shed chips may prick the workers' palms, and at the same time, it is not convenient for the subsequent collection work of the bar stock. By adding a cleaning component, the surface of the bar stock can be cleaned while the bar stock is moving and being conveyed, avoiding the cumbersome subsequent manual cleaning and improving the working efficiency of the device.

A grinding component 4 is fixedly connected to one side of the inner cavity of the main body housing 1. A guiding component 5 is fixedly connected to one side of the inner cavity of the main body housing 1 close to the baffle 3. A cleaning component 6 is fixedly connected to the outer surface of the main body housing 1 away from the grinding component 4. A detection component 7 is fixedly connected to one end of the outer surface of the baffle 3 away from the main body housing 1. A sliding rod 12 is rotatably connected to the inner cavity of the main body housing 1. The sliding rod 12 penetrates through the inner wall of the baffle 3, and the outer surface of the sliding rod 12 is slidably connected to the inner wall of the baffle 3. A threaded rod 11 is threadedly connected to the middle of the inner cavity of the main body housing 1. The threaded rod 11 penetrates through the inner wall of the baffle 3, and the outer surface of the threaded rod 11 is threadedly connected to the inner wall of the baffle 3. A straightening roller 8 is fixedly connected to the top of the outer surface of the baffle 3. During operation, by rotating the threaded rod 11, the threaded rod 11 rotates in the inner cavity of the main body housing 1, so that the threaded rod 11 drives the two baffles 3 to move relatively, thereby adjusting the size of the straightening spacing according to the size of different bars, so that the straightening roller 8 straightens the bar.

[0018] The detection component 7 includes a detection shaft 71. A detection block 72 is fixedly connected to one end of the outer surface of the detection shaft 71 away from the baffle 3. A detection spring 73 is sleeved on the outer surface of the detection shaft 71. A fixing rod 74 is fixedly connected to the middle of one end of the outer surface of the detection block 72 close to the detection shaft 71. An induction plug 75 is fixedly connected to one end of the fixing rod 74 away from the detection block 72. An induction socket 76 is fixedly connected to the middle of one end of the baffle 3 close to the detection shaft 71. During the bar straightening process, due to the stretching action of the detection spring 73, the detection block 72 abuts against the bar during processing, so as to detect the outer surface of the bar. When the outer surface of the bar is damaged and there is a drop outside the error range, the induction plug 75 abuts against the induction socket 76, so that the detection component 7 issues an alarm to remind the operator.

[0019] The grinding component 4 includes a grinding plate 41. At the top of the outer surface of the grinding plate 41, a grinding block 42 is fixedly connected. At the top of the outer surface of the grinding plate 41, a connecting rod 43 is fixedly connected. One end of the connecting rod 43 away from the grinding plate 41 is slidably connected to a clamping plate 44. A grinding spring 45 is sleeved on the outer surface of the connecting rod 43. One end of the grinding spring 45 close to the grinding plate 41 is fixedly connected to the top of the outer surface of the grinding plate 41. One end of the grinding spring 45 away from the grinding plate 41 is fixedly connected to the bottom of the outer surface of the clamping plate 44.

One end of the outer surface of the grinding belt 49 away from the pulley 410 is rollingly connected to the middle of the outer surface of the output end of the motor 47; During operation, the bar to be processed is placed into the grinding component 4. By pulling the clamping plate 44, the bar to be processed is fixed. While the bar moves, the burrs of the bar are removed and ground by the grinding block 42 on the grinding plate 41. At the same time, by turning on the motor 47, the fan blade 48 is driven to rotate in the inner cavity of the main body housing 1. At the same time, the rotation of the output end of the motor 47 drives the grinding belt 49 to rotate. Through the transmission of the grinding belt 49, the pulley 410 drives the fan blade 48 to rotate, so that the waste chips generated during grinding are adsorbed on the filter screen plate 46 through the rotation of the fan blade 48.

[0020] The guiding component 5 includes a guiding shaft 51. The outer surface of the guiding shaft 51 is fixedly connected to the bottom of the inner cavity of the main body housing 1. At the top of the outer surface of the guiding shaft 51, a guiding plate 52 is slidably connected. In the inner cavity of the guiding plate 52, a roller shaft 53 is rotatably connected. On the outer surface of the guiding shaft 51, a sliding groove 54 is formed. In the inner cavity of the sliding groove 54, a large connecting rod 55 is rotatably connected through a socket. One end of the large connecting rod 55 away from the sliding groove 54 is rotatably connected to a slider 56. One end of the outer surface of the slider 56 close to the guiding plate 52 is slidably connected to the outer surface of the guiding plate 52. One end of the outer surface of the slider 56 away from the guiding plate 52 is fixedly connected to a blocking block 57. At the bottom of the inner cavity of the sliding groove 54, a guiding spring 58 is fixedly connected. One end of the guiding spring 58 away from the bottom of the inner cavity of the sliding groove 54 is fixedly connected to one end of the large connecting rod 55 away from the slider 56; When the bar passes through the guiding component 5, due to the weight of the bar itself, the guiding plate 52 slides on the guiding shaft 51, so that the large connecting rod 55 slides in the inner cavity of the sliding groove 54 through the socket. Thus, by the pulling of the large connecting rod 55, the slider 56 slides on the outer surface of the guiding plate 52, driving the blocking block 57 to limit the bar on the guiding component 5. Through the continuous movement of the bar, the bar continuously slides through the roller shaft 53 in the inner cavity of the guiding plate 52.

[0021] The cleaning component 6 includes a cleaning plate 61. At the top of the outer surface of the cleaning plate 61, a cleaning frame 62 is slidably connected. Inside the cavity of the cleaning frame 62, cleaning rollers 63 are evenly arranged. In the middle of the outer surface of the cleaning frame 62, a small connecting rod 64 is rotatably connected through a socket. At one end of the small connecting rod 64 away from the cleaning frame 62, a guiding block 65 is rotatably connected through a socket. At the top of the outer surface of the guiding block 65, friction blocks 66 are evenly arranged. In the middle of the outer surface of the guiding block 65, a connecting shaft 67 is slidably connected. One end of the connecting shaft 67 away from the guiding block 65 is fixedly connected to the inner wall of the main body housing 1. A cleaning spring 68 is sleeved on the outer surface of the connecting shaft 67. One end of the cleaning spring 68 close to the guiding block 65 is fixedly connected to the outer surface of the guiding block 65, and the other end of the cleaning spring 68 away from the guiding block 65 is fixedly connected to the inner wall of the main body housing 1. After the bar stock completes the straightening work, when the bar stock reaches the cleaning component 6 through the guiding component 5, due to the continuous movement of the bar stock, it abuts against the guiding block 65. Through the frictional force generated between the bar stock and the friction blocks 66, the guiding block 65 is driven to move upward on the connecting shaft 67. While the guiding block 65 is moving, it pulls the small connecting rod 64 to move, so that the small connecting rod 64 drives the cleaning frame 62 to move on the cleaning plate, thereby enabling the cleaning rollers 53 in the cavity of the cleaning frame 62 to perform surface cleaning treatment on the processed bar stock.
