Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a tool steel bar rolling anti-deviation positioning device. Background Technology

[0002] High-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance. It is also known as high-speed tool steel or high-speed steel, and is commonly called white steel. High-speed tool steel is usually produced by hot rolling process.

[0003] A bar rolling guide die, disclosed in CN210586361U, includes a die frame with a cylindrical guide device inserted through it. Adjustable guide plates are correspondingly arranged on both sides of the cylindrical guide device and the inner wall of the die frame. A guide roller is vertically clamped at one end of each adjustable guide plate. A rotating support rod is horizontally arranged on the side wall of the die frame, and the adjustable guide plate is suspended from the rotating support rod via its side wall. Pressure bearings are sleeved at both ends of the guide roller. The cylindrical guide device and the guide roller at one end of the adjustable guide plate accurately ensure the direction of bar billet transport, solving the problem of bar billets easily impacting the die. Adjustable bolts allow adjustment of the opening size of the guide roller according to the diameter of the bar billet, accommodating bar billets of different diameters.

[0004] However, the patent still has the following problems in actual use: after the device guides the steel bar through rolling, if the steel bar does not meet the size requirements (such as diameter or length deviation) after the initial rolling, it needs to be corrected by repeated rolling. The device is only convenient for guiding the initial rolling, but not for guiding the subsequent repeated rolling process, which reduces the rolling effect of the steel bar.

[0005] Therefore, a tool steel bar rolling anti-deviation positioning device is proposed to solve the above-mentioned problems. Utility Model Content

This device is only convenient for initial rolling guidance, but not for subsequent repeated rolling processes, which reduces the rolling effect of the steel bar.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tool steel bar rolling anti-deviation positioning device, comprising two conveying units and two symmetrically arranged fixed frames, wherein the conveying unit includes a side frame, a first servo motor, a driving roller and a driven roller, and two side frames are arranged in parallel;

[0008] A first servo motor is fixedly installed on the outside of one side frame, and an active roller and multiple driven rollers are rotatably installed on the inner sides of the two side frames in sequence.

[0009] Also includes:

[0010] The output end of the first servo motor is fixedly connected to the active roller. The active roller and multiple driven rollers are synchronously driven by a single belt. The same crossbar is fixedly installed on one side of the top of the two side frames. Guide plates are symmetrically fixedly connected to the side of the crossbar away from the fixed frame. A feed port is opened in the middle of the inside of the crossbar.

[0011] The top of the fixed frame is fixedly connected to a support rod, the top of the support rod is fixedly connected to a top plate, an upper electric push rod is fixedly installed inside the top plate, and a U-shaped plate is fixedly connected to the bottom of the telescopic end of the upper electric push rod.

[0012] A movable seat is slidably mounted on the top of the side frame. An inner groove is opened on one side of the movable seat. A second servo motor is fixedly installed inside the inner groove. A lead screw is fixedly connected to the output end of the second servo motor. An adjustment plate is fixedly connected to the outside of the lead screw. A lifting plate is fixedly connected to one side of the adjustment plate.

[0013] Preferably, there are at least three driven rollers, the guide plate is located on top of the driving roller, the guide plate is inclined, and the inner bottom surface of the feed inlet is at the same level as the top surface of the driving roller.

[0014] Preferably, there are at least two support rods, the U-shaped plate is located below the top plate, a lower servo motor is fixedly installed on the outside of one side of the fixed frame, a lower roller is rotatably connected between the two fixed frames, and the output end of the lower servo motor is fixedly connected to the lower roller.

[0015] Preferably, an upper servo motor is fixedly installed on the outer side of the U-shaped plate, and an upper roller is rotatably connected inside the U-shaped plate. The output end of the upper servo motor is fixedly connected to the upper roller.

[0016] Preferably, a lower electric push rod is fixedly installed on the side of the side frame away from the driven roller. A connecting plate is fixedly connected to the telescopic end of the lower electric push rod. A top rod is fixedly connected to the upper outer side of the connecting plate.

[0017] Preferably, the inner groove is located on one side of the two movable seats that are close to each other, and there are at least two inner grooves. A base plate is fixedly connected to the lower part of the inner groove.

[0018] Preferably, the bottom end of the lead screw is rotatably connected to the base plate, the adjusting plate is in contact with the inner wall of the inner groove, and the lifting plate is located between the two driven rollers.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a lower electric push rod, a top rod, a moving seat, a base plate, a second servo motor, a lead screw, an adjusting plate, and a lifting plate, after the steel bar undergoes initial rolling, the operator starts the lower electric push rod, which drives the connecting plate and the top rod to move. At the same time, the second servo motor drives the lead screw to rotate, so that the moving seat on one side pushes and guides the steel bar, and the lifting plate on that side flips the steel bar. The moving seat on the other side pushes the flipped steel bar to the rolling position, thereby facilitating the guidance and anti-deviation of the steel bar during multiple rolling processes and realizing the adjustment of different surfaces of the steel bar for rolling processing, thus improving the rolling processing quality of the steel bar. The specific details are as follows:

[0020] By setting up a lower electric push rod, a top rod, a movable seat, a base plate, a second servo motor, a lead screw, an adjusting plate, and a lifting plate, after the steel bar undergoes initial rolling, the operator activates the lower electric push rod. The lower electric push rod drives the connecting plate and the top rod to move, and the top rod drives the movable seat to move. The movable seat pushes the steel bar, facilitating the adjustment of the steel bar's longitudinal position. Simultaneously, the second servo motor drives the lead screw to rotate, causing the adjusting plate to rise. The adjusting plate then drives the lifting plate to rise, and the lifting plate flips the steel bar. The movable seat on one side pushes and guides the steel bar, and the lifting plate on that side flips the steel bar. The movable seat on the other side pushes the flipped steel bar to the rolling position, thus facilitating the guidance and anti-deviation of the steel bar during multiple rolling processes. It also enables the adjustment of different surfaces of the steel bar for rolling processing, improving the rolling quality of the steel bar and ensuring that the dimensions of the rolled steel bar meet the requirements.

[0021] By setting up horizontal bars, guide plates, feed inlets, upper electric push rods, lower servo motors, lower rolls, U-shaped plates, upper servo motors, and upper rolls, when the steel bar is input to the position of the drive roll, it is first guided by the guide plate, causing the steel bar to move closer to the feed inlet. Then, the feed inlet limits the steel bar, maintaining stable and anti-deviation conveying of the steel bar on the drive and driven rolls. Next, the steel bar is conveyed to the processing position of the lower and upper rolls. The operator simultaneously starts the lower and upper servo motors. The lower servo motor drives the lower roll to rotate, and the upper servo motor drives the upper roll to rotate, thereby performing rolling processing on the steel bar. Furthermore, by starting the upper electric push rod, the contraction and extension of the upper electric push rod will drive the U-shaped plate to rise and fall, thus facilitating flexible adjustment of the height of the upper roll.

[0029] 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.

[0030] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a tool steel bar rolling anti-deviation positioning device, comprising two conveying units and two symmetrically arranged fixed frames 8. The conveying unit includes a side frame 1, a first servo motor 2, a driving roller 3 and a driven roller 4, and two side frames 1 are arranged in parallel.

[0031] A first servo motor 2 is fixedly installed on the outside of one side frame 1, and an active roller 3 and multiple driven rollers 4 are rotatably installed on the inside of the two side frames 1.

[0032] The output end of the first servo motor 2 is fixedly connected to the active roller 3. The active roller 3 and multiple driven rollers 4 are synchronously driven by a single belt. The same horizontal bar 5 is fixedly installed on one side of the top of the two side frames 1. The guide plate 6 is symmetrically fixedly connected on the side of the horizontal bar 5 away from the fixed frame 8. The feed port 7 is opened in the middle of the interior of the horizontal bar 5.

[0033] When the steel bar is fed to the position of the drive roller 3, it is first guided by the guide plate 6, so that the steel bar moves closer to the feed port 7. Then the feed port 7 limits the steel bar to maintain stable and anti-deviation conveying of the steel bar on the drive roller 3 and the driven roller 4.

[0034] There are at least three driven rollers 4, and the guide plate 6 is located on top of the driving roller 3. The guide plate 6 is inclined, and the inner bottom surface of the feed inlet 7 is at the same level as the top surface of the driving roller 3.

[0035] Among them, the top of the fixed frame 8 is fixedly connected to the support rod 9, the top of the support rod 9 is fixedly connected to the top plate 10, the top plate 10 is fixedly installed inside the top plate 10, and the bottom of the telescopic end of the top electric push rod 11 is fixedly connected to the U-shaped plate 14.

[0036] There are at least two support rods 9, the U-shaped plate 14 is located below the top plate 10, a lower servo motor 12 is fixedly installed on the outside of one side of the fixed frame 8, and a lower roller 13 is rotatably connected between the two fixed frames 8. The output end of the lower servo motor 12 is fixedly connected to the lower roller 13.

[0037] An upper servo motor 15 is fixedly installed on the outer side of the U-shaped plate 14, and an upper roller 16 is rotatably connected inside the U-shaped plate 14. The output end of the upper servo motor 15 is fixedly connected to the upper roller 16.

[0038] The steel bar is conveyed to the processing position of the lower roll 13 and the upper roll 16. The operator starts the lower servo motor 12 and the upper servo motor 15 at the same time. The lower servo motor 12 drives the lower roll 13 to rotate, and the upper servo motor 15 drives the upper roll 16 to rotate, thereby rolling the steel bar. By starting the upper electric push rod 11, the contraction and extension of the upper electric push rod 11 will drive the U-shaped plate 14 to rise and fall, thereby facilitating flexible adjustment of the height of the upper roll 16.

[0039] A movable seat 20 is slidably mounted on the top of the side frame 1. An inner groove 21 is opened on one side of the movable seat 20. A second servo motor 23 is fixedly installed inside the inner groove 21. A lead screw 24 is fixedly connected to the output end of the second servo motor 23. An adjustment plate 25 is fixedly connected to the outside of the lead screw 24. A lifting plate 26 is fixedly connected to one side of the adjustment plate 25.

[0040] After the steel bar undergoes its initial rolling, the operator activates the lower electric push rod 17. The lower electric push rod 17 moves the connecting plate 18 and the top rod 19, which in turn moves the moving seat 20. The moving seat 20 pushes the steel bar to facilitate adjustment of its longitudinal position. Simultaneously, the second servo motor 23 drives the lead screw 24 to rotate, causing the adjusting plate 25 to rise. The adjusting plate 25 then moves the lifting plate 26 to rise, which flips the steel bar. The moving seat 20 on one side guides the steel bar, and the lifting plate 26 on that side flips the steel bar. The moving seat 20 on the other side pushes the flipped steel bar to the rolling position, thus facilitating multiple rolling cycles and preventing deviation. This allows for the adjustment of different surfaces of the steel bar for rolling, improving the rolling quality and ensuring that the dimensions of the rolled steel bar meet the requirements.

[0041] A lower electric push rod 17 is fixedly installed on the side of the side frame 1 away from the driven roller 4. A connecting plate 18 is fixedly connected to the telescopic end of the lower electric push rod 17. A top rod 19 is fixedly connected to the upper outer side of the connecting plate 18. The top rod 19 is fixedly connected to the movable seat 20.

[0042] The inner groove 21 is located on the side where the two movable seats 20 are close to each other. There are at least two inner grooves 21. A base plate 22 is fixedly connected to the lower part of the inner groove 21. The bottom end of the lead screw 24 is rotatably connected to the base plate 22. The adjusting plate 25 is in contact with the inner wall of the inner groove 21. The lifting plate 26 is located between the two driven rollers 4.

[0043] Working principle:

[0044] Before using this tool steel bar rolling anti-deviation positioning device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, when the steel bar is fed to the position of the drive roller 3, it is first guided by the guide plate 6, causing the steel bar to approach the feed port 7. Then, the feed port 7 limits the steel bar, maintaining stable and anti-deviation conveying of the steel bar on the drive roller 3 and the driven roller 4. Next, the steel bar is conveyed to the processing position of the lower roller 13 and the upper roller 16. The operator simultaneously starts the lower servo motor 12 and the upper servo motor 15. The lower servo motor 12 drives the lower roller 13 to rotate, and the upper servo motor 15 drives the upper roller 16 to rotate, thereby performing rolling processing on the steel bar. After the steel bar has undergone the initial rolling, the operator starts the lower electric push rod 17. The lower electric push rod 17 drives the connecting plate 18 and the push rod 19 to move. 19 drives the movable seat 20 to move, and the movable seat 20 pushes the steel bar to facilitate adjustment of the longitudinal position of the steel bar. At the same time, the second servo motor 23 drives the lead screw 24 to rotate. The rotation of the lead screw 24 causes the adjusting plate 25 to rise. The adjusting plate 25 drives the lifting plate 26 to rise. The lifting plate 26 flips the steel bar. The movable seat 20 on one side pushes and guides the steel bar, and the lifting plate 26 on that side flips the steel bar. The movable seat 20 on the other side pushes the flipped steel bar to the rolling position, which facilitates the guidance and anti-deviation of the steel bar during multiple rolling processes. It also realizes the adjustment of different surfaces of the steel bar for rolling processing, improves the rolling processing quality of the steel bar, and ensures that the dimensions of the rolled steel bar meet the requirements.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
