Description

Technical Field

[0001] This application relates to the field of steel straightening technology, and in particular to a high-speed wire rod feeding and straightening device. Background Technology

[0002] The high-speed wire rod exit roller conveyor is a transport roller conveyor that carries steel billets heated in the heating furnace to the rolling mill for rolling. Currently, there is an electromagnetic induction heating device on this transport roller conveyor near the rolling mill. This device performs secondary heating of the steel billets to ensure the stability of the steel billet temperature after exiting the furnace. However, the steel billet passage opening of this electromagnetic induction device is small. When the steel billet exiting the furnace bends or deforms, it will either collide with the electromagnetic induction device and damage the equipment, or it will be unable to enter the electromagnetic induction device, increasing the need to remove the steel billet and seriously affecting the rolling production.

[0011] The first telescopic component is connected between the free ends of the two vertical roller frames. The clamping and straightening of the clamping roller is achieved by the extension and retraction of the first telescopic component.

[0012] Furthermore, the horizontal straightening device includes:

[0013] There are two horizontal roller frames arranged in parallel, with a wire straightening space between the two horizontal roller frames;

[0014] The straightening roller is rotatably mounted on one side of the horizontal roller frame near another horizontal roller frame;

[0015] The second telescopic component is used to drive the two horizontal roller frames closer to / away from each other.

[0016] Furthermore, the vertical clamping device also includes:

[0017] The first proximity sensor is used to detect the head end of the billet;

[0018] The first controller is configured to control the first telescopic member to drive the second vertical roller frame to flip toward the direction of the first vertical roller frame when the first proximity sensor detects the billet head end.

[0019] The horizontal straightening device also includes:

[0020] A second proximity sensor is used to detect the head end of the billet; and

[0021] The second controller is configured to control the second telescopic member to drive the two horizontal roller frames closer together when the second proximity sensor detects the head end of the billet.

[0022] Furthermore, the first proximity sensor is disposed on the side of the clamping bracket facing the conveying direction of the conveying roller, and the detection surface of the first proximity sensor is tangent to the outer circumference of the clamping roller.

[0023] The second proximity sensor is located on the side of the horizontal roller frame facing the conveyor roller conveyor in the direction of transport, and the second proximity sensor is close to the side of the straightening roller of the vertical clamping device closest to the front end.

[0024] Furthermore, the clamping bracket is provided with a front guide plate and a rear guide plate at its front and rear ends along the conveying direction of the conveying rollers, respectively, for guiding the head end of the billet. Both the front guide plate and the rear guide plate are flared and their flared ends to constricted ends are arranged along the conveying direction of the conveying rollers.

[0025] Furthermore, a lower guide plate is fixedly connected to the lower end face of the front guide plate. The lower guide plate is inclined, with the higher end of the lower guide plate close to the clamping bracket and not higher than the top surface of the clamping roller on the first vertical roller frame.

[0026] Furthermore, it also includes:

[0027] Cooling pipes are connected to an external cooling water source;

[0028] The spray pipes are connected to the cooling pipes and there are multiple spray pipes. Spray holes are opened on the side wall of the spray pipes near the adjacent pinch rolls or straightening rolls.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. When the billet exiting the furnace exhibits a tilting phenomenon, the two vertically distributed pinch rolls are initially in an open state, providing sufficient space for the tilted billet to enter between them. When the first proximity sensor detects that the billet head is about to enter between the two pinch rolls, the first controller activates the first telescopic component to drive the second vertical roller frame to rotate on the pinch support towards the first vertical roller frame. This reduces the distance between the two pinch rolls and vertically straightens the tilted billet head. Furthermore, since the upper pinch roll approaches the lower pinch roll through the rotation of the second vertical roller frame on the pinch support, effective straightening of the wire rod bend can be ensured in a relatively labor-saving manner.

[0038] 2. When the second proximity sensor detects that the billet head is about to enter between the two sets of straightening rollers, the second controller controls the two second telescopic components to work simultaneously, driving the two horizontal roller frames closer to each other, and using the multiple straightening rollers between the two horizontal roller frames to straighten the billet head in the horizontal direction. Thus, the straightening device of this application can automatically straighten the billet head in both the vertical and horizontal directions, facilitating the conveying of the billet into the electromagnetic induction device, and requiring no personnel to be on duty.

[0039] 3. By installing spray pipes on both the sides of the pinch roll and the straightening roll, and supplying cooling water to the spray pipes through cooling pipes, cooling water can be sprayed onto the pinch roll and the straightening roll through the spray holes on the spray pipes, thereby reducing the working temperature of the pinch roll and the straightening roll and ensuring production safety.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] Reference Figure 1 This application discloses a high-speed wire rod feeding and straightening device, which includes a horizontal straightening device 22 and two vertical feeding devices 11. The horizontal straightening device 22 is located between the two vertical feeding devices 11, and the three are arranged sequentially along the conveying direction of the conveying roller. That is, the head end of the billet exiting the furnace first enters a vertical feeding device 11, then enters the horizontal straightening device 22, and then enters another vertical feeding device 11 to achieve vertical-horizontal-vertical straightening.

[0055] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The vertical clamping device 1 includes:

[0056] The clamping bracket 111 is fixedly installed.

[0057] The first vertical roller frame 112 is fixedly mounted on the clamping bracket 111, and one end of the first vertical roller frame 112 is reserved for a free connection end;

[0058] The second vertical roller frame 113 is hinged at one end to the clamping bracket 111 and the other end is a free connection end. The second vertical roller frame 113 and the first vertical roller frame 112 are spaced apart in the vertical direction.

[0059] The pinch rollers 12 are respectively installed between two vertical roller frames, and the space between the two pinch rollers 12 on the two vertical roller frames is the wire clamping and straightening space.

[0060] The first telescopic member 13 is connected between the free ends of the two vertical roller frames. The clamping and straightening of the clamping roller 12 is achieved by the extension and retraction of the first telescopic member 13. Specifically, the first telescopic member 13 consists of two linear drive members distributed at both ends along the axial direction of the clamping roller 12. One end of the linear drive member is hinged to the second vertical roller frame 113 and the other end is hinged to the first vertical roller frame 112. The linear drive member can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0061] The first proximity sensor 14, used to detect the head end of the steel billet, is specifically disposed on the side of the clamping bracket 111 facing the conveying direction of the transport roller, and the detection surface of the first proximity sensor 14 is tangent to the outer circumference of the clamping roller 12; and

[0062] The first controller is configured to control the first telescopic member 13 to drive the second vertical roller frame 113 to flip toward the direction of the first vertical roller frame 112 when the first proximity sensor 14 detects the head end of the billet.

[0063] Specifically, refer to Figure 1 The horizontal straightening device 2 includes:

[0064] There are two horizontal roller frames 21 arranged in parallel, and the space between the two horizontal roller frames 21 is the wire straightening space;

[0065] A straightening roller 22 is rotatably mounted on one side of a horizontal roller frame 21 near another horizontal roller frame 21, and at least two straightening rollers 22 are provided on one horizontal roller frame 21.

[0066] The second telescopic member 23 is used to drive the two horizontal roller frames 21 closer to / away from each other, and there are two second telescopic members 23, one second telescopic member 23 corresponding to one horizontal roller frame 21; four parallel guide rails 61 are installed on the ground, and guide rods 62 are slidably arranged on the guide rails 61. The horizontal roller frame 21 is fixedly connected to the two guide rods 62 on the same side. The second telescopic member 23 is fixedly connected to the ground and its output end is fixedly connected to the adjacent horizontal roller frame 21.

[0067] The second proximity sensor 24, used to detect the head end of the billet, is positioned on the side of the horizontal roller frame 21 facing the conveying direction of the transport roller table, and is close to the side of the straightening roller 22 of the vertical clamping device 1 closest to the front end; and

[0068] The second controller is configured to control the second telescopic member 23 to drive the two horizontal roller frames 21 closer together when the second proximity sensor 24 detects the head end of the billet.

[0069] The first proximity sensor 14 and the second proximity sensor 24 can both be infrared sensors, specifically including an infrared emitting end and an infrared receiving end. When the billet head passes between the infrared emitting end and the infrared receiving end, it can block the infrared rays emitted by the infrared emitting end, so that the first proximity sensor 14 and the second proximity sensor 24 emit electrical signals, which can realize non-contact proximity sensing of the billet head.

[0070] Furthermore, referring to Figure 1 and Figure 2 The straightening device of this application further includes:

[0071] A drive motor 51 is installed on one side of the clamping bracket 111;

[0072] The reduction gearbox 53 has its input end connected to the output end of the drive motor 51 via a coupling 52. It has two output ends, both of which rotate at the same speed but in opposite directions.

[0073] The universal joint 54 is connected at one end to the output end of the reduction gearbox 53 and at the other end to the end of a pinch roller 12.

[0074] The guardrails 55 are set on both sides of the length of the universal joint 54. This setting is for safety production considerations. The guardrails 55 are set at the universal joint 54 to prevent people from accidentally entering and causing accidents.

[0075] Therefore, when the billet exiting the furnace exhibits a tilting phenomenon, the two vertically distributed pinch rolls 12 are initially in an open state, providing sufficient space for the tilted billet to enter between them. When the first proximity sensor 14 detects that the billet head is about to enter between the two pinch rolls 12, the first controller controls the first telescopic component 13 to operate, causing the second vertical roller frame 113 to flip on the pinch support 111 towards the first vertical roller frame 112. This reduces the distance between the two pinch rolls 12 and vertically straightens the tilted billet between them. Moreover, since the upper pinch roll 12 approaches the lower pinch roll 12 through the flipping of the second vertical roller frame 113 on the pinch support 111, effective straightening of the wire rod bend can be ensured in a relatively labor-saving manner.

[0076] Simultaneously, the two sets of straightening rollers 22 on the two horizontal roller frames 21 are initially in the open state. When the second proximity sensor 24 detects that the billet head is about to enter between the two sets of straightening rollers 22, the second controller controls the two second telescopic members 23 to work simultaneously, driving the two horizontal roller frames 21 closer to each other, and using the multiple straightening rollers 22 between the two horizontal roller frames 21 to straighten the billet head in the horizontal direction. Thus, the straightening device of this application can automatically straighten the vertical and horizontal directions of the billet head, facilitating the conveying of the billet into the electromagnetic induction device, and eliminating the need for personnel to be on duty.

[0077] The transmission motor 51, the reduction gearbox 53 and the universal joint 54 enable the two clamping rollers 12 in the clamping device 1 in the same vertical direction to rotate in opposite directions at the same speed, so as to continuously and stably transport the steel billet; even if the vertical height of the upper clamping roller 12 changes, it can still maintain stable rotation.

[0078] In addition, to ensure that the bend at the head of the billet can smoothly enter the vertical clamping device 1, refer to Figure 1A front guide plate 31 and a rear guide plate 32 are respectively provided at the front and rear ends of the clamping bracket 111 along the conveying direction of the conveying rollers to guide the head end of the billet. Both the front guide plate 31 and the rear guide plate 32 are trumpet-shaped, and their flared ends to constricted ends are arranged along the conveying direction of the conveying rollers. In addition, a lower guide plate 33 is fixedly connected to the lower end face of the front guide plate 31. The lower guide plate 33 is inclined, and the higher end of the lower guide plate 33 is close to the clamping bracket 111 but not higher than the top surface of the lowermost clamping roller 12. In this way, it can be smoothly ensured that the bend at the head end of the billet can smoothly enter between the upper and lower distributed clamping rollers 12 for vertical straightening.

[0079] Meanwhile, considering the high operating temperature of the straightening device in this application, refer to Figure 1 , Figure 4 and Figure 5 The straightening device of this application further includes:

[0080] Cooling pipe 41 is connected to an external cooling water source;

[0081] The spray pipe 42 is connected to the cooling pipe 41 and is provided in multiple ways. Spray holes 421 are opened on the side wall of the spray pipe 42 near the adjacent pinch roll 12 or straightening roll 22. Multiple spray holes 421 can be opened as needed. Specifically, the spray pipe 42 corresponding to the pinch roll 12 is set on the horizontal side of the pinch roll 12, and the spray pipe 42 corresponding to the straightening roll 22 is set on the side of the straightening roll 22 away from the other set of straightening rolls 22, so that the spraying operation of the spray pipe 42 will not interfere with the normal transmission of the steel billet.

[0082] A water tank is located below the clamping support 111 and the horizontal roller frame 21, and is used to collect cooling water after spraying to ensure the cleanliness and tidiness of the production site.

[0083] The implementation principle of a high-speed wire rod feeding and straightening device according to an embodiment of this application is as follows:

[0084] When the billet exiting the furnace exhibits a tilting motion, the two vertically distributed pinch rolls 12 are initially open, providing sufficient space for the tilted billet to enter between them. When the first proximity sensor 14 detects that the billet head is about to enter between the two pinch rolls 12, the first controller controls the first telescopic component 13 to operate, causing the second vertical roller frame 113 to flip on the pinch support 111 towards the first vertical roller frame 112. This reduces the distance between the two pinch rolls 12 and vertically straightens the tilted billet. Furthermore, since the upper pinch roll 12 approaches the lower pinch roll 12 via the flipping of the second vertical roller frame 113 on the pinch support 111, effective straightening of the wire rod bend can be ensured in a relatively labor-saving manner.

[0085] Simultaneously, the two sets of straightening rollers 22 on the two horizontal roller frames 21 are initially in the open state. When the second proximity sensor 24 detects that the billet head is about to enter between the two sets of straightening rollers 22, the second controller controls the two second telescopic members 23 to work simultaneously, driving the two horizontal roller frames 21 closer to each other, and using the multiple straightening rollers 22 between the two horizontal roller frames 21 to straighten the billet head in the horizontal direction. Thus, the straightening device of this application can automatically straighten the vertical and horizontal directions of the billet head, facilitating the conveying of the billet into the electromagnetic induction device, and eliminating the need for personnel to be on duty.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
