DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1 to 4The present invention discloses a high-speed steel feeding system brake pinch roller, comprising:

[0036] Box;

[0037] Two roller power boxes are symmetrically arranged in the box body, one end of the roller power box is rotatably arranged in the box body, the output end of the roller power box is drivingly connected to the roller 4, the two roller power boxes are drivingly connected, and the input end of any roller power box is drivingly connected to the driving part;

[0038] A rotating rod 9 is rotatably arranged in the middle part of the box body, and one end of a connecting plate 10 is hinged on both sides of the rotating axis of the rotating rod 9, and the other end of the connecting plate 10 is hinged to the end of the corresponding roller power box. One end of the rotating rod 9 away from the connecting plate 10 is transmission-connected with a rotating part for driving the rotating rod 9 to rotate. When the rotating rod 9 rotates, it drives the two roller power boxes to move closer to or away from each other.

[0039] When in use, one end of the rotating rod 9 is driven to move through the rotating part, so that the rotating rod 9 rotates. When the rotating rod 9 rotates, the two connecting plates 10 are driven to move, and then the corresponding roller power boxes are pulled to rotate. Since the connecting plates 10 are symmetrically arranged on both sides of the rotating axis of the rotating rod 9, the two roller power boxes are moved closer or farther away from each other, and then the two rollers 4 are driven closer or farther away. The gap between the two rollers 4 can be quickly adjusted, and then the clamping force can be quickly adjusted. Since the two roller power boxes act at the same time, the axis of the gap between the two rollers 4 does not change, thereby improving the efficiency of adjusting the gap between the two rollers 4.

[0040] As an optional embodiment, the roller power box includes a roller ring box body seat 3, a gear transmission shaft 2 is rotatably arranged in the middle of the roller ring box body seat 3, and both ends of the gear transmission shaft 2 are rotatably arranged on the inner wall of the box body;

[0041] The gear transmission shaft 2 is meshed with a gear shaft 1, which is rotatably arranged in a roller ring housing seat 3, and one end of the gear shaft 1 passes through the inner wall of the housing and is connected to the roller 4;

[0042] The end of the roller ring housing seat 3 is hinged to the end of the connecting plate 10 away from the rotating rod 9;

[0043] The gear transmission shafts 2 of the two roller power boxes are meshed;

[0044] One end of the gear transmission shaft 2 of any roller power box is in transmission connection with the input end of the driving part.

[0045] As an optional implementation, a limiting portion is provided on the top of the box body, and the limiting portion cooperates with the top limiting portion of the roller ring box body seat 3 located above the box body.

[0046] As an optional implementation, the limiting portion includes two limiters 23 , and the two limiters 23 are respectively matched with the top ends of the corresponding roller ring box seat 3 .

[0047] In the conveying state, the stoppers 23 are adjusted so that the two stoppers 23 abut against the two ends of the top of the roller ring housing seat 3, thereby preventing the roller ring housing seat 3 from rotating.

[0048] During equipment debugging, the gap between the two rollers 4 is adjusted by adjusting the lengths of the two stoppers 23 respectively, thereby adjusting the angle range of the forward and reverse rotation of the roller ring housing seat 3.

[0049] By such an arrangement, not only the response time of the roller 4 action is improved, but also the clamping force of the roller 4 is increased.

[0050] As an optional embodiment, the rotating part includes a pneumatic device 25, the fixed end of the pneumatic device 25 is fixedly connected to the top of the box, the movable end of the pneumatic device 25 is hinged to one end of the connecting rod 12, and the other end of the connecting rod 12 is hinged to one end of the rotating rod 9.

[0051] The pneumatic device 25 is selected as a cylinder, and the air pressure of the pneumatic device 25 is controlled by a pneumatic solenoid valve and a PLC controller. The clamping force of the brake pinch roller is converted into a standard electrical signal by controlling the pneumatic solenoid valve and input into the PLC. The change of the gap between the two rollers 4 is controlled according to the program set in the PLC to meet the functions of clamping head, clamping tail, full-process clamping and rapid braking of the rolled piece in high-speed bar production, and then transmitted to the computer in the main control room. The computer can instantly display the real-time changing clamping force of the brake pinch roller through the corresponding program and supporting equipment, and when the clamping force of the brake pinch roller does not reach the process set value, it can alarm and trip in time, so that the equipment can reach the best operating state, which is particularly suitable for the needs of actual production processes.

[0052] As an optional embodiment, the box body includes an upper box body 20, a middle box body 21 and a lower box body 22 which are fixed in sequence;

[0053] The gear transmission shaft 2 located at the top is rotatably arranged between the upper housing 20 and the middle housing 21;

[0054] The gear transmission shaft 2 located at the bottom is rotatably arranged between the middle box body 21 and the lower box body 22;

[0055] Slots for the gear shaft 1 to move are provided between the upper box body 20 and the middle box body 21 , and between the middle box body 21 and the lower box body 22 .

[0056] From the perspective of structural design, the upper, middle and lower boxes are designed to facilitate assembly and subsequent maintenance.

[0057] As an optional implementation, the roller ring box seat 3 includes a roller ring box 14 , and roller ring box covers 15 are respectively fixedly connected to both sides of the roller ring box 14 , and the roller ring box covers 15 are rotatably disposed on the gear transmission shaft 2 .

[0058] As an optional implementation, a sealing ring 19 is provided in the groove, and the sealing ring 19 is used to prevent debris from entering the box body. The sealing ring 19 is fixed to the outside of the box body through a panel 26.

[0059] Furthermore, considering the sealing performance, double-lip sealing rings 19 and purge are added between the gear shaft 1 and the box body to prevent the rolled piece from entering the water tank and then entering the box body; considering the practical application, water cooling is added to the roll 4 to reduce the wear of the roll ring and extend the service life; the left and right lines are the same equipment, which reduces the spare parts inventory of the steel plant.

[0060] Compared with the traditional technology, the present invention has the following technical effects:

[0061] At present, the maximum rolling speed of brake pinch rollers at home and abroad is 45m / s, while the design speed of the brake pinch rollers developed by us is 65m / s, which guarantees a working speed of 60m / s, far exceeding the performance indicators of the same type of pinch rollers. The production specifications are wide ranging from φ10-φ32mm, which can meet the production needs of many steel mills; the larger speed increase ratio reduces the cost of users to purchase power devices; the brake pinch rollers can clamp the rolled pieces, provide stable support and clamping force, and prevent the rolled pieces from deflecting, twisting or jumping during transportation. The stable clamping force can ensure that the bars always run along the established track, reducing the accident rate in the production process; providing a certain traction force for the bars can improve the efficiency of steel loading, reduce the resistance during steel loading, and reduce energy consumption.

[0062] This structural design fundamentally solves the problem of automatic centering of the pinch rollers. The pneumatic device 25 controls the connecting rod mechanism to enable the upper and lower roller ring box seats to clamp and release synchronously, thereby achieving precise control of the speed of the bar. The innovative design of the pneumatic device 25 driving the rotation mechanism to move not only improves the response time of the pinch roller action, but also increases the clamping force of the pinch roller. The clamping force can be changed by controlling the pneumatic components through the PLC, thereby achieving a rapid braking effect. Considering the structural design, the upper, middle and lower boxes are designed to be more convenient for assembly and later maintenance. Considering the sealing performance, double lip seals and purges are added to the roller shaft and the box to prevent water from entering the box after the rolled piece enters the water tank. Considering practical application, water cooling is added to the pinch roller rings to reduce roller ring wear and extend service life. The left and right lines are the same equipment, which reduces the spare parts reserve of the steel plant.

[0063] Controlling low temperature rolling can achieve fine grain structure, save alloy and reduce production cost; rolling with modular rolling mill can improve the dimensional accuracy of finished products and the yield rate; the cooling bed on the drum can reduce the flying steel accident and ensure that the product rod is not bent; improving the wear-resistant material of the roller ring, reducing the time of roller replacement and size adjustment, and improving the operation rate; low furnace temperature can save energy consumption. Compared with the original high bar pinch roller, it has a simple structure, is easy to use and maintain, and can be effectively and quickly mass-produced.

[0064] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0065] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
