Description

Technical Field

[0001] The invention relates to the technical field of roll neck protection, in particular to a roll neck protection mechanism for roll quenching. Background Art

[0002] Rollers are mainly divided into three categories: cast steel rolls, cast iron rolls and forged rolls. There are also a small number of carbide rolls on profile rolling mills. On the rolling mill, the rolls are the components that cause the rolled metal to undergo plastic deformation, and are mainly composed of the roll body and roll diameter.

[0003] The quenching treatment of traditional rolling mill rolls requires the use of lifting equipment to vertically point one end of the rolling mill roll upwards, and the use of a sling to clamp the upward roller diameter of the rolling mill roll until the upward roller diameter is tightened. The lifted rolling mill roll can then be transferred to the quenching furnace by the sling, and then the rolling mill roll needs to be turned over by the lifting equipment until it is quenched as a whole. However, there are certain defects in the above-mentioned lifting process from turning over, lifting to turning over. Since the surface of the rough rolling mill roll is affected by moisture and static electricity, a large amount of particulate matter will adhere to the surface of the roller diameter. After the roller diameter is quenched, oxidized carbon deposits will form on its surface. Therefore, after being clamped by the sling, the particulate matter or oxidized carbon deposits will affect the locking force of the sling on the rolling mill roll, and then the rolling mill roll after transportation will be prone to fall off during the suspended rotation.

[0004] In view of this, a roll neck protection mechanism for roll quenching is designed to solve the above problems. Summary of the invention

[0046] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0047] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0048] A roll neck protection mechanism for roll quenching provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0049] Combination Figure 1-Figure 9 As shown, the present invention provides a roll neck protection mechanism for roll quenching, comprising a suspension mechanism 400 and a roll neck locking mechanism 100, a roll diameter cleaning mechanism 200 arranged on the roll neck locking mechanism 100, and a roll diameter auxiliary pressure mechanism 300 arranged on the roll neck locking mechanism 100, the suspension mechanism 400 is arranged on the roll diameter auxiliary pressure mechanism 300 and the roll neck locking mechanism 100, the suspension mechanism 400 is used to provide a centering calibration force and a bearing force for the roll suspension, the roll diameter auxiliary pressure mechanism 300 is used to provide kinetic energy for the locking of the roll, the roll diameter cleaning mechanism 200 is used to clean the carbon on the roll diameter surface, and the roll neck locking mechanism 100 is used to tighten rolls of different sizes.

[0050] The roll neck locking mechanism 100 includes two reset compression springs 140 and two clamps 150, a neck protection assembly 110 for adapting to roll diameters of different sizes, and two sleeves 120 for limiting, two pressure rods 130 arranged inside the two sleeves 120, a support plate 160 arranged on the neck protection assembly 110, and a neck dirt cleaning assembly 180 arranged in the support plate 160, and the two clamps 150 are respectively installed on the two pressure rods 130, and the reset compression spring 140 is pressed between the inner wall of the sleeve 120 and the clamp 150, and is used to provide a reset thrust for the pressure rod 130;

[0051] A slideway is provided on the outside of the sleeve 120, and the plate body of the clamp 150 passes through the outside of the slideway;

[0052] The roller cleaning mechanism 200 includes two winding rollers 240, two shaping soft plates 260, two support rods 210 and two pads 220. The two ends of the shaping soft plates 260 are respectively wound and rolled in the annular grooves outside the two winding rollers 240 and the polishing belt 270 installed outside the shaping soft plates 260.

[0053] The roller diameter auxiliary pressure mechanism 300 includes a limiting column head 310 disposed directly above the neck protection assembly 110 and a lifting plate 320 movably mounted outside the limiting column head 310;

[0054] A convex ring is provided at the bottom of the limiting column head 310, and the lifting plate 320 is composed of a ring buckle, two end plates and a pressure plate, and a through hole is provided in the middle of the pressure plate;

[0055] A clamping seat 330 is disposed in each of the two end plates, the bottom end of the clamping seat 330 is a flat clamping plate, and two nuts are disposed on the threaded section of the clamping seat 330;

[0056] The suspension mechanism 400 includes a hydraulic component 420 , a beam plate 410 bearing pressure on the limiting column head 310 , and a suspension rod 440 for suspension support. An external frame 430 is installed in the middle of the beam plate 410 .

[0057] After the traditional roller is clamped by the hoist and transported to the top of the quenching furnace, the roller fixed by the hoist can be extended into the interior of the quenching furnace. When the lower half of the roller is immersed in the quenching furnace, oxidized carbon deposits will be generated on the surface of the lower half of the roller. When the oxidized carbon deposits solidify after cooling, the flipped roller is flipped by the lifting equipment, and the roller diameter with oxidized carbon deposits will face upward. At this time, due to the interference of oxidized carbon deposits and impurities, the locking of the roller diameter by the hoist will become loose. When the roller is lifted and the entire device cooperates with the roller to rotate, under the influence of centrifugal force and gravity, the roller can easily fall off from the inside of the hoist, thereby posing a safety hazard to the surrounding workers.

[0058] The device sets the clamp of the traditional clamping method as a centrally spliced ​​structure. When the suspension rod 440 is fixed, the limiting column head 310 installed at the bottom of the suspension rod 440 can cooperate with the pressure-resistant sleeve 111 to provide clamping force for the upward roller diameter of the roller. At this time, the center of gravity of the suspended roller can be consistent with the suspension rod 440. At this time, the roller is delivered to the quenching furnace for heat treatment after suspension, and the rotation of the roller can be maintained constant, which reduces the centrifugal phenomenon of the roller due to the non-unique center of gravity. As the hydraulic component 420 runs, its internal hydraulic sub-rod will push the lifting plate 320 to climb at a uniform speed. Finally, the two clamp seats 330 installed in the lifting plate 320 can simultaneously stretch the two traction frames 340. At this time, the two cantilevers 350 will simultaneously pull the two clamps 150 to stretch at equal intervals. At this time, the two pressure rods 130 constrained by the two shaft sleeves 120 can be pushed toward the cylindrical cavity inside the pressure-resistant sleeve 111.

[0059] When the roller diameter is continuously delivered to the inside of the pressure-resistant sleeve 111 and the limiting column head 310, the two pressure rods 130 extending at the same speed can compress and lock the roller diameter. When the neck dirt cleaning assembly 180 arranged at the bottom of the pressure-resistant sleeve 111 is in high-frequency vibration cutoff, the grinding belt 270 pressed against the roller diameter along the inside of the base 181 can clean the oxidized carbon deposits and impurity particles, thereby improving the locking force of the two pressure rods 130 on the cleaned roller diameter. Embodiment 2:

[0060] Combination Figure 3-Figure 6 As shown, based on the embodiment 1, the neck protection assembly 110 includes a pressure-resistant sleeve 111, a cylindrical cavity is opened inside the pressure-resistant sleeve 111, and a pad 112 is arranged in the annular groove at the bottom end of the pressure-resistant sleeve 111;

[0061] The inner cavities of the two shaft sleeves 120 are connected to the cylindrical cavity inside the pressure-resistant sleeve 111;

[0062] The pressure rod 130 is in a T-shaped structure as a whole, and the end of the pressure rod 130 that penetrates into the cylindrical cavity in the pressure-resistant sleeve 111 is provided with a concave surface adapted to bear pressure on the outer wall of the roller diameter;

[0063] The interior of the limiting column head 310 is provided with a socket adapted to fit into the cylindrical cavity in the pressure-resistant sleeve 111 , and the socket is used to provide a calibrated constraint for the rotation of the roller.

[0064] By setting a protective pad 112 at the bottom of the pressure-resistant sleeve 111, when the high-frequency vibrator 190 is running, the base 181 that obtains high-frequency traction can improve the rapid cleaning of carbon deposits and impurity particles on the roller diameter without damaging the bottom port of the pressure-resistant sleeve 111. At the same time, the four guide rods 182 installed on the base 181 cooperate with the four springs 183 to be located directly below the support plate 160 for constant pressure vibration. As the two winding rollers 240 rotate in opposite directions, the wound shaping soft plate 260 can tighten the grinding belt 270 on the outside of the roller diameter. At this time, the grinding belt 270 accompanied by the vibration of the base 181 can efficiently clean the roller diameter that continues to extend into the interior of the pressure-resistant sleeve 111. Embodiment three:

[0065] Combination Figure 2-Figure 6 As shown, based on the first embodiment, four vertical holes are opened in the plate surface of the support plate 160 close to the pressure-resistant sleeve 111;

[0066] The neck dirt cleaning assembly 180 includes a base 181 attached to the outer wall of the pressure-resistant sleeve 111, four guide rods 182 installed on the base 181, a spring 183 arranged outside the guide rods 182, and two rollers 184, and the rollers 184 are composed of end rods and sleeve rollers;

[0067] Two I-shaped guide slots are formed inside the base 181 , and two rollers 184 are disposed in the two guide slots.

[0068] By fixing the support plate 160 on the outer wall of the pressure-resistant sleeve 111, when the motor 170 installed inside the support plate 160 is started, its internal transmission shaft will drive one of the transmission shafts 230, and the winding roller 240 and the gear 250 installed outside the transmission shaft 230 can be driven at the same speed. At this time, the two winding rollers 240 under constraint can reel in the two ends of the shaping soft plate 260, and cooperate with the two rotating rollers 184 to bear the pressure on the outside of the grinding belt 270, while reducing the friction resistance of the grinding belt 270 along the outer wall of the roller diameter, thereby ensuring that roller diameters of different sizes can be quickly adapted to the brush vibration after passing through the inside of the grinding belt 270. Embodiment 4:

[0069] Combination Figure 2-Figure 6 As shown, based on Example 1, one of the pads 220 is installed in the middle of the two support rods 210, and the other pad 220 is installed at the bottom of the two support rods 210;

[0070] Two symmetrically distributed transmission shafts 230 are arranged inside the two pads 220, and a gear 250 is installed outside the transmission shaft 230. The gear 250 is arranged on the top of the winding roller 240, and two adjacent gears 250 are adapted to mesh;

[0071] A motor 170 is installed inside the support plate 160, and a cross-shaped rod is installed at the bottom end of the transmission shaft inside the motor 170; a hole suitable for the cross-shaped rod is opened at the top of the transmission shaft 230, and the transmission shaft 230 is used to drive the winding roller 240 and reel in the shaping soft board 260.

[0072] According to the requirements of the high-frequency vibration amplitude of the shaping soft plate 260 and the grinding belt 270, the two struts 210 can be movably installed inside the support plate 160, and the sub-springs are used to provide a reset force for the two stretched struts 210. At this time, one of the transmission shafts 230 can cooperate with the cross-shaped plug rods on the inner transmission shaft of the motor 170 to perform appropriate lifting and lowering. At this time, the two winding rollers 240 that can be adapted and lifted along the cross-shaped plug rods can adjust the vibration amplitude of the grinding belt 270, thereby increasing the cleaning range of dirt on the roller surface and reducing the wear caused by the small force area of ​​the roller. Embodiment five:

[0073] Combination Figure 3-Figure 9 As shown, on the basis of Example 1, a traction frame 340 is movably mounted on the clamping plate at the bottom end of the clamping seat 330, and a cantilever 350 is movably mounted at the bottom end of the traction frame 340;

[0074] A bolt is disposed in the threaded hole at the outer end of the cantilever 350, and a gasket is disposed outside the bolt;

[0075] A groove is provided at the bottom of the annular end of the beam plate 410, and the groove is adapted to bear pressure on the top of the convex ring, and the bottom of the convex ring is pressed in the groove at the top of the pressure-resistant sleeve 111;

[0076] The annular end of the beam plate 410 and the top end of the compression sleeve 111 are locked by a plurality of combined bolts;

[0077] The outer frame 430 is an L-shaped structure as a whole, and the rod body of the outer frame 430 is adapted to penetrate into the through hole in the middle of the pressure plate;

[0078] A nut is provided on the stud at the top end of the hydraulic sub-rod in the hydraulic component 420, and the nut is pressed tightly against the top of the pressure plate.

[0079] The beam 410 and the pressure-resistant sleeve 111 are fixed with multiple combination bolts. At this time, the limit column head 310 clamped by the beam 410 and the pressure-resistant sleeve 111 can maintain a constant center of gravity with the suspension rod 440. When the hydraulic component 420 is running, its internal hydraulic sub-rod will lift the lifting plate 320 and steadily rise. At this time, the two clamp seats 330 installed in the lifting plate 320 can pull the two traction frames 340. At this time, the two inclined traction frames 340 will stretch the two cantilevers 350 to contract at the moment of compression, and the clamp 150 and the pressure rod 130 constrained by the inner cavity of the two shaft sleeves 120 can extend into the cylindrical cavity in the pressure-resistant sleeve 111. At this time, the roller diameter after cleaning can be pressed by the two pressure rods 130 without damage, thereby preventing the roller from being locked and rotating after suspension and falling off.

[0080] The working principle and use process of the present invention are as follows: when the roller is quenched, the worker needs to use a lifting device to place the roller diameter at one end of the roller vertically along the ground, and then clamp the hanger on the outside of the roller diameter. The roller diameter after vertical adjustment according to the above process needs to be pre-wiped with a towel until the rough impurity particles on the outside of the roller diameter are cleaned. At this time, the interference of the rough impurity particles on the friction resistance between the hanger and the roller diameter can be reduced. When the upward roller diameter of the roller is suspended, the lower half of the roller transported to the quenching furnace can be preheated by the quenching furnace. After the lower half of the roller is quenched, the hanger drives the roller to transfer outward from the quenching furnace. With the temperature imbalance, oxidized carbon deposits will appear on the preheated surface of the lower half of the roller.

[0081] At the same time, the rolls transferred to the outside of the quenching furnace need to be turned over by equipment until the lower half that has been quenched is turned upward. The temperature of the roll that has been turned upward and quenched is higher, so the oxidized carbon deposits on its surface become difficult to be quickly and effectively processed manually. Therefore, the sling will slip under the action of gravity on the roll with oxidized carbon deposits, and then fall.

[0082] Therefore, the device sets an adaptable and matching pressure-resistant sleeve 111 for the roller diameters at both ends of the roller in the low-temperature state and the high-temperature state. At this time, the pressure-resistant sleeve 111 and the limiting column head 310 can constrain the upward roller diameter of the roller. At the same time, after the roller diameter passes through the inner side of the grinding belt 270, after the motor 170 is running, the cross-shaped plug rod at the bottom end of its internal transmission shaft will drive one of the transmission shafts 230, and with the meshing transmission of the two gears 250, the two winding rollers 240 adapted and constrained by the two pads 220 and the two support rods 210 can control the two ends of the shaping soft plate 260. The mechanical energy is wound up at the same speed until the grinding belt 270 arranged on the outside of the shaping soft plate 260 tightens the outside of the roller diameter. At the same time, the operation of the high-frequency vibrator 190 and the base 181 supported by the auxiliary pressure of four springs 183 will drive the tightened grinding belt 270 to perform high-frequency and vertical brushing along the outer wall of the roller diameter. At this time, the oxidized carbon deposits on the outside of the roller diameter that need to be clamped can be quickly and efficiently cleaned, and as the roller continues to extend radially toward the upper roller toward the inner cavity of the pressure-resistant sleeve 111 and the limiting column head 310, the carbon deposits on the tightened surface of the roller can be continuously cleaned.

[0083] When the oxidized carbon deposits on the pressure-bearing parts of the above-mentioned roller surface are cleaned, the hydraulic component 420 can be operated. At this time, the hydraulic sub-rod in the hydraulic component 420 will push the lifting plate 320 to be stably lifted upward along the outside of the limiting column head 310. At this time, the two clamping seats 330 installed on the lifting plate 320 will cooperate with the two traction frames 340 to pull the two cantilevers 350 for stable lifting. At this time, the two cantilevers 350 will shrink relatively, and the clamping component 150 will push the pressure rod 130. At this time, the two pressure rods 130 penetrate into the two column heads in the inner cavity of the pressure-resistant sleeve 111, and the clean parts of the roller diameter surface can be pressed and fixed. At this time, the roller diameter can be tightened in a state without interference from impurities after quenching, thereby ensuring that the roller diameters at both ends of the roller can be perfectly locked by the device from before to after treatment.

[0084] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
