Description

Technical Field

[0001] The invention belongs to the technical field of hot-rolled narrow strip production and is also applicable to other similar mechanical occasions. It specifically relates to an automatic clamping device for clamping a hot-rolled narrow strip into a clamping roller. Background Art

[0002] In the existing production of hot-rolled narrow steel strips, after the steel strips pass through the outlet of the finishing mill and then through the twisting guide plate, the horizontal steel strips are twisted and erected, and after passing through the guide groove of the serpentine oscillator, they are transported and cooled on the flat conveyor, which is equivalent to the steel strips being temporarily "collected". After passing through the flat conveyor, the steel strips need to be sent to the pinch rollers for subsequent coiling by the coiler, but after coming out of the guide groove of the serpentine oscillator, the steel strips are freely placed on the flat conveyor. The steel strips are mostly S-shaped, and the head of the steel strips is relatively free and straight, with an uncertain position. The position and posture of each roll of the strip head on the flat conveyor are different, but the bending radius of the subsequent steel strips gradually decreases, and they are basically placed in an S shape.

[0003] In many domestic production lines, the head of the steel strip cannot be automatically inserted into the pinch roller at the back. Instead, workers have to stand on a flatbed conveyor and use a long-handled clamp to first adjust the position of the steel strip head. Then, they use the clamp to clamp the steel strip and feed it into the pinch roller. Such manual operation greatly reduces production efficiency. More importantly, since the temperature of the steel strip is 500-600℃, workers are very likely to get burned when operating at close range, and the operating environment is extremely dangerous. Summary of the invention

[0004] In view of the above-mentioned shortcomings and deficiencies, the purpose of the present invention is to provide a simple and safe automatic clamping and feeding device for hot-rolled narrow strips, which does not require workers to operate at close range, can effectively improve production efficiency, and can avoid the occurrence of on-site safety accidents.

[0005] In order to achieve the above object, the technical solution of the present invention is:

[0006] A hot-rolled narrow strip automatic clamping device comprises a clamping guide plate, a clamping mechanism and a clamping mechanism; there are two clamping guide plates, which are vertically arranged between a flat conveyor and a clamping roller, and the end of the clamping guide plate close to the clamping roller is set as a pivot end, and the end of the clamping guide plate away from the clamping roller is set as an opening and closing end; there are two groups of clamping mechanisms, which are respectively arranged on the outer sides of the two clamping guide plates and connected to the two clamping guide plates, and the clamping mechanism can drive the two clamping guide plates to rotate so that the opening and closing ends are brought together or opened; there are two groups of clamping mechanisms, which are respectively arranged on the two clamping guide plates, and the slider of the clamping mechanism is connected to the clamping head, and the two clamping heads are relatively arranged on the inner sides of the two clamping guide plates, and the two clamping heads can clamp the steel strip head and be driven by the clamping mechanism to send the steel strip head to the roller gap of the pinch roller.

[0007] The device also includes a transition guide plate, which is arranged between the flat conveyor and the pinch roller.

[0008] The device also includes side guide plates arranged on both sides of the flatbed conveyor, and the extended sections of the side guide plates are arranged in an eight-shaped shape from the flatbed conveyor to the pinch rollers, and the eight-shaped side guide plates are installed on the transition guide plates; a rotating shaft is provided at one end of the eight-shaped side guide plate close to the pinch rollers, the rotating shaft is fixed on the transition guide plate, and a rotating sleeve is installed on the rotating shaft and can rotate around the axis of the rotating shaft; the pinch guide plate is located on the inner side of the eight-shaped side guide plate, and the pivot end of the pinch guide plate is fixedly connected to the rotating sleeve and can rotate around the axis of the rotating shaft with the rotating sleeve.

[0009] The clamping mechanism adopts a rod cylinder, the cylinder body of the rod cylinder is pivoted on a mounting seat in a rotatable manner, the mounting seat is fixed on a base on the outer side of the side guide plate, a long hole is provided on the side guide plate for the piston rod to pass through, the piston rod head of the rod cylinder passes through the long hole and is movably pivoted on the outer side of the opening and closing end of the clamping guide plate, when the piston rods of the rod cylinders of the two clamping mechanisms are extended, the opening and closing ends of the two clamping guide plates are pushed together, and when the piston rods of the rod cylinders of the two clamping mechanisms are retracted, the opening and closing ends of the two clamping guide plates are pulled open.

[0010] The clamping mechanism adopts a rodless cylinder, which is installed on the outside of the clamping guide plate. A sliding groove is opened in the middle of the clamping guide plate. The clamping head arranged on the inner side of the clamping guide plate passes through the sliding groove and extends to the outside of the clamping guide plate and is connected to the slider of the rodless cylinder. The rodless cylinder drives the clamping head to slide back and forth along the sliding groove with the help of the slider.

[0011] A first detection element for detecting the steel belt is installed on both sides of the end of the flatbed conveyor or on the side guide plates on both sides of the end of the flatbed conveyor. The first detection element sends the signal of detecting the steel belt to the control center of the device, and the control center controls the clamping mechanism to drive the clamping guide plate to perform clamping and guiding actions.

[0012] A second detection element for detecting the steel strip is installed on the opening and closing end of the clamping guide plate. The second detection element sends the signal of detecting the steel strip to the control center of the device. The control center controls the clamping mechanism to drive the clamping guide plate to perform a rapid clamping action and controls the clamping mechanism to drive the clamping head to clamp and move forward.

[0013] A pressure detection element is installed on the clamping mechanism (specifically, a pressure detection element for detecting the pressure of the rodless cylinder circuit can be installed on the rodless cylinder). The pressure detection element sends a signal of a sudden increase in pressure to the control center of the device, and the control center controls the clamping mechanism to drive the clamping guide plate to open.

[0014] When the two pinch guide plates are rotated to be close to each other and clamped, the gap between the two pinch guide plates and the center line of the flatbed conveyor and the center of the roller gap between the pinch rollers are in the same plane.

[0015] A guide plate is provided on the inner side of the clamping guide plate before the steel strip enters the clamping head to prevent the head of the steel strip from being held up by the front end of the clamping head and being unable to enter between the two clamping heads for clamping.

[0016] The contact surface of the clamping head for clamping the steel strip is provided with a buffer pad, which is convenient for clamping the steel strip and mitigating the impact.

[0017] After adopting the above scheme, the present invention has a simple structure and is easy to maintain and operate. The basic principle is: after the steel belt runs onto the flatbed conveyor through the guide groove of the serpentine oscillator, it moves forward with the flatbed conveyor, and the clamping mechanism is used to drive the two clamping guide plates to rotate so that the opening and closing ends gradually come together. Until they are completely close together, the two clamping heads contact the two side surfaces of the steel belt head and clamp the steel belt head, and then the clamping mechanism is used to drive the slider so that the clamping head also moves forward with the slider, and the steel belt tightly clamped by the two clamping heads is also dragged forward, and moves forward all the way to the roller gap of the clamping roller. After the steel belt is bitten into the roller gap of the clamping roller by the clamping roller, it continues to be pulled forward, and then the clamping mechanism is used to drive the two clamping guide plates to rotate to open the opening and closing ends, and the distance between the clamping heads on both sides of the steel belt gradually increases. The steel belt is only transported by the clamping roller to the subsequent equipment operation, and the work of clamping the steel belt into the clamping roller is completed once. The present invention makes the operation of passing the steel belt into the pinch roller more time-saving and labor-saving, and the entire equipment is safe and reliable. At the same time, it avoids the operator from frequently operating in the dangerous area, and effectively reduces the occurrence of safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figures 1 to 4 As shown, the present invention discloses an automatic clamping device for hot-rolled narrow strips, including a clamping guide plate 10, a clamping mechanism and a clamping mechanism. There are two clamping guide plates 10, and the two clamping guide plates 10 are vertically arranged between the flat conveyor 2 and the clamping roller 4. The clamping roller 4 is arranged at the end of the flat conveyor 2. The end of the clamping guide plate 10 close to the clamping roller 4 is set as a pivot end, and the end of the clamping guide plate 10 away from the clamping roller 4 is set as an opening and closing end. The clamping mechanism can adopt the rod cylinder 8 shown in the figure but is not limited to the structure shown in the figure. There are two groups of clamping mechanisms, which are respectively arranged on the outside of the two clamping guide plates 10 and connected to the two clamping guide plates 10. The clamping mechanism can drive the two clamping guide plates 10 to rotate around the pivot end, so that the opening and closing ends of the clamping guide plates 10 are close to each other until the clamping function is realized or the clamping function is released by opening. The clamping mechanism can adopt the rodless cylinder 16 shown in the figure but is not limited to the structure shown in the figure. There are two groups of clamping mechanisms, which are respectively arranged on the two clamping guide plates 10. The slider 17 of the clamping mechanism is connected to the clamping head 12. The two clamping heads 12 are relatively arranged on the inner sides of the two clamping guide plates 10. The two clamping heads 12 can clamp the head of the steel strip 3, and the head of the steel strip 3 is driven by the clamping mechanism to be sent to the roller gap of the clamping roller 4.

[0032] The present invention utilizes a clamping mechanism to drive the opening and closing ends of the two pinching guide plates 10 to gradually approach, and guides the head of the steel strip 3 to gradually align with the roller gap of the pinching roller 4, until the opening and closing ends of the two pinching guide plates 10 are completely approached and clamped, and the two clamping heads 12 clamp the head of the steel strip 3, and then utilize the clamping mechanism to drive the two clamping heads 12 to tightly clamp the steel strip 3 and move forward until it is sent into the roller gap of the pinching roller 4, at which time the clamping mechanism is utilized to drive the opening and closing ends of the two pinching guide plates 10 to open, and the clamping heads 12 release the clamping of the steel strip 3, and the steel strip 3 is driven by the pinching roller 4 to continue to be pulled forward, and is transported to the subsequent equipment for operation. The entire operation of pinching the steel strip 3 into the pinching roller 4 is more time-saving and labor-saving, avoiding the operator from frequently operating in the dangerous area, and effectively reducing the occurrence of safety accidents.

[0033] The optimized design of the present invention is that the automatic clamping device also includes a transition guide plate 5, which is provided between the flatbed conveyor 2 and the clamping roller 4, and the transition guide plate 5 plays a role in supporting and guiding the steel belt 3 to move forward. Further, the automatic clamping device also includes side guide plates 1 arranged on both sides of the flatbed conveyor 2, and the extension section of the side guide plate 1 is arranged in an eight-shaped shape from the flatbed conveyor 2 to the clamping roller 4. The eight-shaped side guide plate 1 is installed on the transition guide plate 5, and the side guide plate 1 and the transition guide plate 5 are used to form a closed clamping space to improve the operation safety. As for the structure of the pivot end of the pinch guide plate 10, it can be as shown in the figure but is not limited to the structure shown in the figure. The end of the figure-eight side guide plate 1 close to the pinch roller 4 is provided with a rotating shaft 6, and the rotating shaft 6 is fixed on the transition guide plate 5. The rotating sleeve 7 is installed on the rotating shaft 6, and the rotating sleeve 7 can rotate around the axis of the rotating shaft 6; the pinch guide plate 10 is located on the inner side of the figure-eight side guide plate 1, and the pivot end of the pinch guide plate 10 is fixedly connected to the rotating sleeve 7, so that the pivot end of the pinch guide plate 10 can rotate around the axis of the rotating shaft 6 together with the rotating sleeve 7.

[0034] The clamping mechanism of the present invention can adopt a rod cylinder 8 as shown in the figure but is not limited to the structure shown in the figure. The cylinder body of the rod cylinder 8 is pivoted on the mounting seat 9 in a rotatable manner. The mounting seat 8 is fixed on a foundation on the outside of the side guide plate 1 (such as a base frame of the device or other relatively stationary objects). A long hole 19 is provided on the side guide plate 1 for the piston rod of the rod cylinder 8 to pass through. After the piston rod head of the rod cylinder 8 passes through the long hole 19, it is movably pivoted to the outside of the opening and closing end of the clamping guide plate 10. In order to facilitate the pivoting, a pivot seat 20 can be installed on the outside of the opening and closing end of the clamping guide plate 10, and the piston rod head can be movably pivoted to the pivot seat 20. When the piston rods of the rod cylinders 8 of the two clamping mechanisms are extended, the opening and closing ends of the two clamping guide plates 10 can be pushed together until they are clamped. When the piston rods of the rod cylinders 8 of the two clamping mechanisms are retracted, the opening and closing ends of the two clamping guide plates 10 can be pulled open to release the clamping.

[0035] The clamping mechanism of the present invention can adopt a rodless cylinder 16 as shown in the figure but is not limited to the structure shown in the figure. The rodless cylinder 16 is installed on the outer side of the clamping guide 10. A sliding groove 11 is opened in the middle of the clamping guide 10. The clamping head 12 arranged on the inner side of the clamping guide 10 passes through the sliding groove 11 and extends to the outer side of the clamping guide 10 and is connected with the slider 17 of the rodless cylinder 16. When the rodless cylinder 16 is actuated, the clamping head 12 is driven to slide back and forth along the sliding groove 11 with the help of the slider 17.

[0036] In order to further improve the degree of automation and enhance the safety and reliability of the equipment, the present invention installs a first detection element 15 on both sides of the end of the flatbed conveyor 2 or specifically on the side guide plates 1 on both sides of the end of the flatbed conveyor 2. The first detection element 15 is used to detect the position of the steel belt 3 entering the device. When the first detection element 15 detects the position signal of the steel belt 3, the signal is sent to the control center of the device. The control center then controls the rod cylinder 8 of the clamping mechanism to drive the clamping guide plate 10 to perform a clamping and guiding action to guide the steel belt 3 to move toward the center line of the flatbed conveyor 2. The present invention installs a second detection element 14 on the opening and closing end of the clamping guide plate 10. The second detection element 14 is used to detect the position of the steel belt 3 in the device. When the second detection element 14 detects the position signal of the steel belt 3, the signal is sent to the control center of the device. The control center then controls the clamping mechanism to drive the clamping guide plate 10 to perform a rapid clamping action, and controls the rodless cylinder 16 of the clamping mechanism to drive the clamping head 12 to perform a clamping and forward action. The present invention also installs a pressure detection element on the clamping mechanism, specifically, the pressure detection element can be installed on the rodless cylinder 16, and the pressure detection element is used to detect the circuit pressure of the rodless cylinder 16. When the pressure detection element detects a sudden increase in pressure, it sends a signal to the control center of the device, and the control center immediately controls the rod cylinder 8 of the clamping mechanism to drive the clamping guide plate 10 to open. Among them, the first detection element 15 and the second detection element 14 can be photoelectric sensors, etc., the pressure detection element can be a pressure sensor, and the control center is a common electromechanical device. The pressure detection element and the control center are not specifically drawn in the figure.

[0037] In order to ensure smooth clamping operation of the device, the present invention provides a guide plate 18 on the inner side surface of the clamping guide plate 10, before the steel strip 3 enters the clamping head 12. The guide plate 18 can guide the head of the steel strip 3 to move to the inner side surface of the clamping head 12, thereby preventing the head of the steel strip 3 from being blocked by the front end of the clamping head 12 and being unable to enter between the two clamping heads 12 for clamping.

[0038] In order to enable the two clamping heads 12 to clamp the head of the steel strip 3 more firmly, the present invention provides a buffer pad 13 on the contact surface of the clamping head 12 for clamping the steel strip 3, which is convenient for clamping the steel strip 3 on the one hand, and plays a role in reducing impact on the other hand, while ensuring that the entire device is protected when the clamping roller 4 pulls the steel strip 3.

[0039] The working principle of the present invention is: after the steel belt 3 runs onto the flatbed conveyor 2 through the guide groove of the serpentine oscillator, it moves forward with the flatbed conveyor 2. After the first detection element 15 arranged on the side guide plate 1 detects the head of the steel belt 3, the control center controls the rod cylinder 8 of the clamping mechanism on both sides to operate, and the clamping guide plate 10 begins to rotate around the axis of the rotating shaft 6 toward the center line of the flatbed conveyor 2. At this time, if the head of the steel belt 3 is close to the clamping guide plate 10 on one side, under the guidance of the clamping guide plate 10, as the subsequent steel belt 3 is pushed forward on the flatbed conveyor 2, the head of the steel belt 3 can slide forward along the inner side of the clamping guide plate 10, and at the same time, move toward the center line of the flatbed conveyor 2 along the clamping guide plate 10. When the second detection element 14 detects the steel strip 3 and sends a signal, it indicates that the head of the steel strip 3 has entered the two clamping guide plates 10 and can be clamped. At this time, the control center controls the rod cylinder 8 to move quickly, and the clamping heads 12 arranged in the sliding grooves 11 of the clamping guide plates 10 on both sides contact and clamp the two side surfaces of the head of the steel strip 3. The clamping guide plates 10 can no longer rotate along the rotating shaft 6. The rod cylinder 8 stops working and locks after the pressure increases. At this time, the control center controls the rodless cylinder 16 of the clamping mechanism to move, and the slider 17 moves forward along the arrangement direction of the rodless cylinder 16. The clamping head 12 connected to the slider 17 also moves forward, and the steel strip 3 tightly clamped by the two clamping heads 12 is dragged forward. The steel strip 3 is clamped by the clamping head 12 and moves along the center line of the flatbed conveyor 2 to the roller gap of the clamping roller 4. The center of the steel strip 3 and the center of the roller gap of the pinch roller 4 are in the same plane. Since the rotation speed of the pinch roller 4 is higher than the forward speed of the slider 17, the steel strip 3 will be pulled forward after being bitten into the roller gap by the pinch roller 4. The clamping head 12 that tightly clamps the steel strip 3 is subjected to a sudden increase in forward pulling force, and the force on the rodless cylinder 16 suddenly increases. Conversely, if the force on the rodless cylinder 16 suddenly increases during its forward movement, it indicates that the steel strip 3 has been fed into the roller gap of the pinch roller 4. At this time, the pressure detection element will detect a sudden increase in the circuit pressure of the rodless cylinder 16 and send it to the control center. The control center controls the piston rods of the rod cylinders 8 on both sides to retract, driving the pinch guide plate 10 to rotate outward along the rotating shaft 6. At the same time, the slider 17 moves in the opposite direction, and the distance between the clamping heads 12 on both sides of the steel strip 3 gradually increases. The steel strip 3 is transported by the pinch roller 4 to the subsequent equipment for operation, and the work of pinching the steel strip 3 into the pinch roller 4 is completed.

[0040] The present invention realizes automatic clamping and feeding of the steel strip 3 into the clamping roller 4, which does not require worker operation, is safe and reliable, and can be applied to new production lines and can also be used for intelligent upgrading and transformation of production lines, and can also be used in similar intelligent mechanical scenes. The present invention greatly improves production efficiency, is fast, and saves time and effort.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that any modification, equivalent replacement, improvement, etc. made by a person skilled in the art within the spirit and principle of the present invention after reading this specification should be included in the protection scope of the present invention.
