Description

Technical Field

[0001] The invention relates to the technical field of roller diameter reduction, in particular to temperature-controlled diameter reduction processing equipment suitable for secondary processing of various types of failed forged steel cold rolling rollers. Background Art

[0002] The failure of forged steel cold rolling rolls mainly manifests itself in the following ways: surface wear, fatigue cracks, spalling, thermal cracks and scratches. Thermal cracks are caused by the high temperature and rapid cooling during the rolling process, which results in thermal stress on the roll surface. Scratches are caused by foreign matter on the surface of the rolled material, equipment failure or improper operation, which results in unexpected conditions on the roll surface. Rollers are generally made of high-strength alloy steel and have a certain degree of thermal stability. However, when the heat generated by cutting causes its temperature to rise significantly, the thermal motion of atoms inside the roll material intensifies and the bonding force between atoms weakens, thereby reducing the yield strength and rigidity of the material.

[0003] In the process of turning and reducing the diameter of traditional rollers, due to the long length of the rollers and the need to rotate quickly, the rollers are easily affected by their own length during high-speed rotation, resulting in serious deviation of the center of gravity of the rollers, causing strong vibration, greatly reducing the processing accuracy, and even causing the rollers to deform and fall off. In addition, a large cutting resistance is generated in the contact area between the turning cutter and the roller, resulting in reduced cutting efficiency of the turning cutter, and even the phenomenon of "cutting off", that is, the turning cutter cannot cut according to the predetermined cutting depth; In view of the above technical defects, a solution is now proposed.

[0009] Furthermore, the side wall of the sleeve is connected to a conduit, the other end of which is connected to an external lubricating oil delivery mechanism, the side wall of the bracket is rotatably connected to a scraper, and a torsion spring is provided at the rotational connection between the scraper and the side wall of the bracket.

[0010] Furthermore, a turning mechanism is provided on one side of the base plate, and a control panel is fixedly connected to the top of the base plate.

[0011] Furthermore, two electric sliding frames are arranged on the top of the base plate, and the electric sliding frames are slidably connected to the top of the base plate.

[0013] 2. When the present invention is in use, by setting the guide frame to an inclined state, the inclined guide rod cooperates with the ball bearings to better adapt to the dynamic changes of the roller during operation. When the roller is subjected to uneven pressure or produces a slight bend, the inclined guide rod uses structures such as compression springs, limit rods and balls to provide more flexible support and adjustment, reduce the deformation and vibration of the roller, and help improve the force distribution on the surface of the roller. The inclined guide rod uses the ball bearings to apply forces of different directions and sizes at different positions, so that the stress distribution on the surface of the roller is more uniform. This arrangement can enhance the guiding and positioning effect on the roller, and solves the problem that the traditional clamping method is horizontally pressed and cannot respond to the instantaneous changes of the roller in time.

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.

[0017] Embodiment 1: Figure 1-Figure 6 As shown, the temperature-controlled shrinking treatment equipment suitable for the secondary processing of various types of failed forged steel cold rolling rollers includes a bottom plate 1, a symmetrical guide rail 4 on the top of the bottom plate 1, a sliding seat 5 is slidably connected inside the guide rail 4, a slide groove 6 is provided on the top of the sliding seat 5, an I-shaped slider 7 is slidably connected inside the slide groove 6, the I-shaped slider 7 and the top of the sliding seat 5 are both slidably connected with a slide rail 8, a slide plate 9 is slidably connected inside the slide rail 8, a bracket 10 is symmetrically fixedly connected to the top of the slide plate 9, a support rod 11 is fixedly connected to the inner side wall of the bracket 10, and a tightening component 12 is provided on the outer side of the support rod 11.

[0018] A turning mechanism 16 is provided on one side of the base plate 1. It should be noted that the turning mechanism 16 is an existing CNC device, which is mainly used for turning and reducing the diameter of the roller. The turning tool of the current turning mechanism 16 is in contact with the bottom of the roller and performs axial turning along the bottom of the roller. At the same time, the turning tool is located between two correspondingly arranged clamping components 12, and a control panel 17 is fixedly connected to the top of the base plate 1.

[0019] Two electric sliding frames 18 are arranged on the top of the bottom plate 1, and the electric sliding frames 18 are slidably connected to the top of the bottom plate 1. The side walls of the electric sliding frames 18 are provided with multi-claw clamps 19, which are used to clamp the ends of the rollers and drive them to rotate at high speed. Due to the large mass of the rollers, in order to realize convenient automatic feeding of the rollers, the side walls of the electric sliding frames 18 are fixedly connected to the limit frame 20, and the limit frame 20 is movably connected with the threaded rod three through the bearing, and the limit frame 20 is slidably connected with the lifting plate 2, and the top of the lifting plate 2 is fixedly connected with the supporting plate 3, and the guide rails 4, the slide rails 8 and the outer sides of the limit frame 20 are respectively provided with motors for driving the threaded rod 13, the threaded rod 2 15 and the threaded rod 3 to rotate; In order to realize automatic loading and unloading of the rollers, the specific operations are as follows: the corresponding motor drives the threaded rod three to rotate, the lifting plate 2 moves synchronously along the limit frame 20 under the action of the threaded rod three, and the supporting plate 3 is used to automatically load and unload the rollers.

[0020] When setting specific Figure 1 As shown, a slide rail 8 is provided on the top of the I-shaped slide block 7 and the slide seat 5, and a clamping assembly 12 is provided on the top of the slide rail 8. The two sets of clamping assemblies 12 on the top of the slide seat 5 are not closely connected, that is, when the turning tool in the turning mechanism 16 is turning at the bottom of the roller, the current two sets of clamping assemblies 12 located on the top of the slide seat 5 are located on both sides of the turning tool. Analyzed along the feeding direction of the turning tool, the clamping assembly 12 located at the front end of the turning tool is used to clamp the roller part that has not been turned or has been turned in the previous round, and the clamping assembly 12 located at the rear end of the turning tool is used to clamp the roller part that is about to be turned or has been turned in the next round. By arranging two sets of clamping components 12 on both sides of the turning tool to provide real-time stable support for it, the stable support can reduce the vibration and deformation of the roller during turning, so that the size after turning is more precise and the surface is smoother and flatter. The clamping component 12 located on the top of the I-shaped slider 7 is used to clamp the outer side of the circumference near the end of the roller, thereby effectively solving the problem that the center of gravity of the roller may be seriously offset during high-speed rotation, resulting in strong vibration, greatly reducing the processing accuracy, and causing the roller to deform, and even the roller to fall off.

[0021] Embodiment 2: The tightening assembly 12 includes an electric push rod 121 and a plurality of connecting seats 122, the connecting seats 122 are fixedly connected to the top and bottom of the support rod 11, the side wall of the support rod 11 is provided with a mounting groove, the electric push rod 121 is installed in the mounting groove, the end of the connecting seat 122 away from the support rod 11 is fixedly connected to a guide frame 123, and the guide frame 123 is inclined, a guide rod 124 is slidably connected in the guide frame 123, one end of the guide rod 124 is fixedly connected to an arc cover plate 125, and the inner side wall of the arc cover plate 125 is fixedly installed with a temperature sensor, such as Figure 1 As shown, the number of the pressing components 12 is 6, and the temperature sensors at the designated positions are used to monitor the temperature of the ends of the rolls and both sides of the roll turning positions in real time, and the rolls are subjected to appropriate temperature control treatment according to the monitoring results; One end of the guide rod 124 away from the arc cover plate 125 is fixedly connected to a connecting block 126, the output end of the electric push rod 121 is fixedly connected to a driving block 127, the top and bottom of the driving block 127 are fixedly connected to a driving rail 128, and the connecting block 126 is slidably connected in the driving rail 128.

[0022] The clamping assembly 12 also includes multiple groups of sleeves 129 and multiple groups of limiting rods 130. The multiple groups of sleeves 129 are fixedly connected to the inner wall of the arc-shaped cover plate 125. The limiting rod 130 is slidably connected in the sleeve 129. A compression spring 1 is arranged in the sleeve 129. The two ends of the compression spring 1 are respectively fixedly connected to the limiting rod 130 and the inner wall of the sleeve 129. One end of the limiting rod 130 located outside the sleeve 129 is fixedly connected to a sleeve 131. The outer side of the sleeve 131 is threadedly connected to a cover cap 132. A rolling groove 133 is opened on one side of the cover cap 132. A ball 134 is arranged in the sleeve 131.

[0023] A threaded rod 13 is provided inside the guide rail 4, and the sliding seat 5 is threadedly connected to the threaded rod 13 through a threaded groove extending through the side wall. An electric push cylinder 14 is fixedly installed inside the sliding seat 5, and the output end of the electric push cylinder 14 is fixedly connected to the side wall of the I-type slider 7. A threaded rod 2 15 is movably connected to the inside of the slide rail 8 through a bearing, and the slide plate 9 is threadedly connected to the threaded rod 2 15 through a threaded groove provided in the side wall.

[0024] The side wall of the sleeve 131 is connected with a conduit 21, and the other end of the conduit 21 is connected with an external lubricating oil delivery mechanism. The side wall of the bracket 10 is rotatably connected with a scraper 22, and a torsion spring is provided at the rotation connection between the scraper 22 and the side wall of the bracket 10. Under the action of the torsion spring, the scraper 22 effectively contacts different positions of the currently reduced diameter roller, so as to facilitate the even application of the lubricating oil. In the specific setting, the turning mechanism 16 moves horizontally along the axial direction of the roller, and performs orderly reduction turning on the roller under the intelligent control of the numerical control. In order to eliminate the strong vibration caused by the center of gravity offset of the roller during high-speed rotation, which causes a large cutting resistance to be generated in the contact area between the turning tool and the roller, resulting in a reduction in the cutting efficiency of the turning tool, and even a "cutting-off" phenomenon, that is, the turning tool cannot cut according to the predetermined cutting depth, the problem of the problem is improved by reasonably arranging the abutting assembly 12 on the outer side of the roller to improve the stable support of the roller; like Figure 1 and Figure 2As shown, the corresponding motor drives the threaded rod 15 to rotate, and the slide plate 9 slides horizontally along the slide rail 8 under the action of the threaded rod 15 until the arc cover plate 125 moves to a position close to the roller, and then the electric push rod 121 is driven, and the electric push rod 121 pushes the driving block 127 to move horizontally, and the driving block 127 cooperates with the connecting block 126 at the end of the guide rod 124 through the top and bottom driving rails 128, thereby driving the guide rod 124 to move in the corresponding "oblique downward" and "oblique upward" directions along the inclined guide frame 123, so that the arc cover plate 125 is evenly distributed on the outer side of the circumference of the roller; The arc cover plate 125 can realize the real-time and effective tightening of the positions of the current rollers with different diameters under the interaction of the electric push rod 121, the drive block 127 and the drive rail 128. The balls 134 inside the arc cover plate 125 can realize the auxiliary tightening of the positions of the current rollers with different diameters, further eliminating the vibration problems caused by the rollers during high-speed rotation and turning. By setting the guide frame 123 to an inclined state, that is, the guide frame 123 located below the level of the roller center is set to "obliquely upward", and the guide frame 123 located above the level of the roller center is set to "obliquely downward", the inclined guide rod 124 can better adapt to the dynamic changes of the roller during operation by using the ball 134. When the roller is subjected to uneven pressure or produces a slight bend, the inclined guide rod 124 can provide more flexible support and adjustment by using the ball 134, reduce the deformation and vibration of the roller, and help improve the force distribution on the roller surface. The inclined guide rod 124 can apply forces of different directions and sizes at different positions by using the ball 134, so that the stress distribution on the roller surface is more uniform, and this arrangement can enhance the guiding and positioning effect on the roller. When the roller is running, it can more effectively prevent the roller from deflecting and shaking, and ensure the stability and accuracy of the rolling process. The horizontal pressing method cannot respond to the instantaneous changes of the roller in time, and the inclined pressing method can adjust and balance the force more quickly, reducing the vibration and deviation of the roller. During the repeated precision turning process of the roller, as the diameter of the roller gradually decreases, the electric push rod 121 is used to adjust the position of the ball 134 in real time to facilitate the real-time tightening of the roller. In addition, during the horizontal turning process of the turning mechanism 16, the threaded rod 13 drives the sliding seat 5 and the tightening assembly 12 on its top to move synchronously under the action of the external motor, so that the corresponding tightening assembly 12 is always located on both sides of the turning tool, which is convenient for real-time tightening of the roller to eliminate vibration. The tightening assembly 12 located above the slide 6 is adjusted in real time to the position close to the other end of the roller under the action of the electric push cylinder 14. By setting multiple clamping points, the vibration generated by the roller when it rotates at high speed can be effectively reduced. During the turning process, the temperature of the roller itself and its surroundings will increase. In order to eliminate the problem of turning accuracy affected by the temperature increase, the temperature sensor monitors the turning position of the roller and the position near the end in real time. If the temperature of the roller position currently monitored is abnormal, the control panel 17 controls the external oil supply mechanism and delivers the lubricating oil to the sleeve 131 through the conduit 21. The ball 134 rolls in the sleeve 131 and carries the lubricating oil to coat the roller surface. The scraper 22 is used to further evenly spread the lubricating oil on the roller surface to reduce heat generation. The reduction in friction will correspondingly reduce the heat generated by friction, which helps to prevent the roller from deforming and wearing due to overheating. If the roller temperature drops next time the roller is turned but the drop in temperature does not meet expectations, continue to apply the lubricating oil. If the roller temperature does not drop next time the roller is turned or there is a trend of rising, the turning of the roller should be stopped immediately.

[0025] like Figure 4 and Figure 5 As shown, the cap 132 and the sleeve 131 are threadedly connected, thereby enabling convenient replacement of the ball 134 and treatment of dirt inside the sleeve 131.
