Description

Technical Field

[0001] The invention relates to the technical field of quenching forged steel support rollers, and in particular to an induction quenching device used for producing forged steel support rollers. Background Art

[0002] The principle of induction hardening is to place the workpiece in the inductor. When an alternating current passes through the inductor, an alternating magnetic field with the same frequency as the current is generated around the inductor, penetrating the metal workpiece placed in the induction coil, and correspondingly generating an induced electromotive force in the workpiece. Electromagnetic induction generates an induced current of the same frequency, namely eddy current. Relying on this current and the resistance of the workpiece itself, the surface of the workpiece is rapidly heated to the quenching temperature, and then immediately cooled by spraying water to harden the surface of the workpiece to obtain a very fine needle-shaped martensite structure. The quenching treatment of large forged steel support rollers is carried out by induction hardening.

[0003] For example, in the prior art, there is a large dual-frequency support roller quenching machine tool with a publication number of CN208071757U. Although the quenching machine tool realizes dual-frequency heating of forged steel support rollers through two sets of quenching devices to achieve high quenching efficiency, after the quenching is completed, due to its simple structure, it is impossible to realize the autonomous replacement of the forged steel support rollers, and it is necessary to additionally equip hoisting equipment for auxiliary loading, which increases the complexity of the overall operation process. In addition, there is a lack of an efficient centering mechanism, which makes it difficult to quickly and accurately realize the automatic centering of the support roller axis and the upper and lower tops during the loading and fixing process of the forged steel support rollers, resulting in the overall quenching efficiency being significantly restricted when multiple forged steel support rollers are continuously processed; In view of the above technical defects, a solution is now proposed.

The hoisting operation is then combined to cause the trapezoidal guide block to move, which can not only perform secondary strengthening clamping on the forged steel support rollers, but also lock the position of the clamping seat synchronously, thereby achieving an anti-slip stable clamping effect during the hoisting and loading process.

A quenching assembly 3 is arranged in the water tank 17, and the quenching assembly 3 includes an annular water retaining cover 31, and a heating coil 32 is installed inside the annular water retaining cover 31. By energizing the heating coil 32 and moving the heating coil 32 to the outside of the forged steel support roller, induction heating of the forged steel support roller is achieved.

[0019] Hydraulic cylinders 14 are symmetrically fixedly installed between the lifting plate 11 and the base 1.

Then, the hydraulic cylinder 14 drives the transverse fixing seat 21 to move downward again. Under the large downward extrusion force, the trapezoidal groove 27 contacts the top of the trapezoidal guide block 28, causing relative sliding between the semicircular clamp block 2 43 and the forged steel support roller, and the free end of the upper center point 22 contacts the top of the forged steel support roller.

[0022] A vertical fixing seat 33 is fixedly connected inside the water storage tank 17, a lifting screw rod 34 is rotatably connected inside the vertical fixing seat 33, a lifting motor 35 for driving the lifting screw rod 34 to rotate is bolted on the vertical fixing seat 33, a lifting block 36 threadedly connected to the lifting screw rod 34 is slidably connected inside the vertical fixing seat 33, and the lifting block 36 is fixedly connected to the annular water shield 31, the hydraulic cylinder 14 drives the clamped forged steel support roller to move upward, and the rotating motor 16 cooperates with the rotating shaft 12 and the rotating plate 13 to transfer the clamped forged steel support roller to the top of the lower top 18 in the water storage tank 17; Then, the forged steel support roller is driven down by the hydraulic cylinder 14, so that the bottom of the forged steel support roller contacts the lower top 18, and cooperates with the upper top 22 to contact the top of the forged steel support roller, so as to complete the fixation of the forged steel support roller in the quenching area, and the lifting motor 35 drives the lifting screw 34 to rotate, and the lifting screw 34 combines with the lifting block 36 to drive the annular water retaining cover 31 to move upward, and the heating coil 32 inside the annular water retaining cover 31 rises on the outside of the forged steel support roller to induction heat the forged steel support roller, and during the rising process of the annular water retaining cover 31, the clamping motor 26 combines with the bidirectional screw 24 and the T-shaped slider 23 to drive the two groups of clamping seats 25 to move apart, so as to avoid the heating coil 32 heating the clamping seat 25 and affecting the service life.

A driven sprocket 38 is fixedly connected to the lower center 18. The driving sprocket 37 and the driven sprocket 38 are connected by a chain 39. When the lifting screw rod 34 rotates, the driving sprocket 37 is driven to rotate, and the lower center 18 is driven to rotate through the chain 39 and the driven sprocket 38, thereby driving the fixed forged steel support roller to rotate, thereby achieving a uniform heating effect.

A water suction pump 312 is installed on the bottom bolts in the water storage tank 17, and a water injection hose 313 is fixedly connected between the water outlet of the water suction pump 312 and the water outlet cavity 310. While the forged steel support roller is induction heated by the heating coil 32 inside the annular water shield 31, the water suction pump 312 draws cooling water in the water storage tank 17 and injects it into the water outlet cavity 310 through the water injection hose 313, and then sprays it onto the heated forged steel support roller through the plurality of water outlet holes 311, and performs immediate water spray quenching treatment to improve the quenching quality.

[0025] Example 2: Please refer to Figure 2-Figure 6 As shown, the problem that it is difficult to ensure the stable clamping of the forged steel support roller by only driving the two sets of clamping seats to move relative to each other through the bidirectional screw can be solved by the following solution; In this embodiment, a trapezoidal groove 27 is provided on one side of the clamping seat 25 near the upper top 22, a trapezoidal guide block 28 is slidably connected in the trapezoidal groove 27, and the two sides of the trapezoidal guide block 28 are symmetrically fixedly connected with the limiting pins 29, and the inner side wall of the trapezoidal groove 27 is provided with a limiting groove 210 slidably connected to the corresponding limiting pin 29, and the limiting pin 29 and the limiting groove 210 are provided, and the inclined surface of the trapezoidal guide block 28 and the trapezoidal groove 27 are slidably fitted together, so that the trapezoidal guide block 28 and the trapezoidal groove 27 can be effectively prevented from being separated; A reset spring 211 is fixedly connected between the bottom of the trapezoidal guide block 28 and the trapezoidal groove 27. The reset spring 211 is set so that after the adaptive clamp 4 is separated from the forged steel support roller, the trapezoidal guide block 28 is pushed up and reset, and then the forged steel support roller is clamped again to ensure effective anti-slip clamping. An adaptive clamp 4 is installed on one side of the trapezoidal guide block 28. After the forged steel support roller is pre-clamped by the two groups of clamping seats 25 carrying the adaptive clamp 4, when the hydraulic cylinder 14 drives the two groups of clamping seats 25 to move upward, the semicircular clamping block 243 and the forged steel support roller are in contact with each other, and the self-gravity of the forged steel support roller first drives the trapezoidal guide block 28 to slide downward in the corresponding trapezoidal groove 27 and compress the reset spring 211. With the help of the trapezoidal groove 27 guiding the trapezoidal guide block 28, the trapezoidal guide block 28 is prompted to carry the adaptive clamp 4 to move toward the forged steel support roller, and as the trapezoidal guide block 28 continues to descend, the clamping force of the semicircular clamping block 2 43 on the forged steel support roller is gradually increased, and a secondary strengthened clamping is performed to drive the forged steel support roller to rise synchronously, so that the forged steel support roller can achieve anti-slip stable clamping during the lifting and loading process.

[0026] A movable block 44 is fixedly connected to one side of the mounting block 41, and a movable groove 212 is provided on the trapezoidal guide block 28 to be slidably connected to the movable block 44. An auxiliary spring 45 is fixedly connected between the movable block 44 and the movable groove 212. Through the cooperation of the movable groove 212, the movable block 44 and the auxiliary spring 45, after the two groups of clamping seats 25 move relative to each other, there is a certain contact friction between the semicircular clamping block 243 and the forged steel support roller, and no large interference force is caused to the secondary descending movement of the transverse fixed seat 21, so that when the clamping seat 25 moves upward, there is no relative sliding problem between the semicircular clamping block 243 and the forged steel support roller.

[0027] A mounting groove 213 connected to the trapezoidal groove 27 is provided on one side of the clamping seat 25, a push plate 214 is rotatably connected inside the mounting groove 213, an L-shaped slideway 215 is symmetrically fixedly connected to one side of the clamping seat 25 away from the trapezoidal groove 27, a clamping plate 216 is slidably connected between the L-shaped slideways 215, and a push rod 217 slidably connected to the push plate 214 is fixedly connected to the clamping plate 216, and a plurality of auxiliary clamping grooves 218 adapted to the clamping plate 216 are equidistantly provided at the bottom of the transverse fixing seat 21 along its length direction; When the trapezoidal guide block 28 slides downward, it abuts against one side of the push plate 214 and forces the push plate 214 to deflect, so that the other side of the push plate 214, in combination with the push rod 217, drives the clamping plate 216 to move upward, inserts the top of the clamping plate 216 into the corresponding auxiliary clamping groove 218, and further locks the position of the clamping seat 25, avoiding the problem that only the two-way screw rod 24 drives the two groups of clamping seats 25 to move relative to each other, which makes it difficult to ensure the stable clamping of the forged steel support roller and reduces the service life of the two-way screw rod 24; After the lower center 18 contacts the forged steel support roller, as the lateral fixed seat 21 continues to descend, and through the contact between the semicircular clamping block 2 43 and the forged steel support roller, the trapezoidal guide block 28 is pushed to slide upward in the corresponding trapezoidal groove 27, thereby driving the clamping plate 216 to slide downward, and after the position lock of the clamping seat 25 is released, the clamping motor 26 is cooperated to drive the two groups of clamping seats 25 to move away from each other.

[0028] Example 3: Please refer to Figure 1-Figure 8 As shown, the present invention also provides a method for using an induction quenching device for producing forged steel support rollers, comprising the following steps: Step 1: The rotating motor 16 cooperates with the rotating shaft 12 and the rotating plate 13 to drive the clamping assembly 2 to rotate to the feeding area of ​​the forged steel support roller. The hydraulic cylinder 14 drives the transverse fixing seat 21 to move downward, so that the two groups of clamping seats 25 are located on both sides of the forged steel support roller. The clamping motor 26 drives the bidirectional screw rod 24 to rotate, and combines with the T-shaped slider 23 to force the two groups of clamping seats 25 to move relative to each other. Step 2: Multiple semicircular clamping blocks 2 43 are connected to the semicircular clamping block 1 42 through sliding connection, and semicircular clamping block 1 42 is connected to the mounting block 41 through sliding connection, so that each semicircular clamping block 2 43 is in contact with the annular outer wall of the forged steel support roller, thereby completing the pre-clamping of the forged steel support roller and forcing the upper center 22 to coincide with the axis of the forged steel support roller. The hydraulic cylinder 14 then drives the transverse fixing seat 21 to move downward again, and relative sliding occurs between the semicircular clamping block 2 43 and the forged steel support roller, so that the upper center 22 abuts against the top of the forged steel support roller. Step 3: The hydraulic cylinder 14 drives the transverse fixing seat 21 to move upward, and during the upward process, through the interference between the semicircular clamp block 2 43 and the forged steel support roller, and the self-weight of the forged steel support roller, the trapezoidal guide block 28 is driven to slide downward in the corresponding trapezoidal groove 27 and compress the reset spring 211, and with the help of the trapezoidal groove 27 to guide the trapezoidal guide block 28, the trapezoidal guide block 28 is synchronously prompted to carry the adaptive clamp 4 to move in the direction of the forged steel support roller for secondary clamping, and further increase the clamping force on the forged steel support roller, so as to drive the forged steel support roller to move upward synchronously; Step 4: While the trapezoidal guide block 28 slides downward, it abuts against one side of the push plate 214, forcing the push plate 214 to deflect. The other side of the push plate 214 combines with the push rod 217 to drive the clamping plate 216 to move upward, and the top of the clamping plate 216 is inserted into the corresponding auxiliary clamping slot 218, further locking the position of the clamping seat 25. Step 5: The hydraulic cylinder 14 drives the clamped forged steel support roller to move upward, and the rotating motor 16 cooperates with the rotating shaft 12 and the rotating plate 13 to transfer the clamped forged steel support roller to the top of the lower top 18 in the water tank 17, and then the bottom of the forged steel support roller is in contact with the lower top 18, and the trapezoidal guide block 28 is simultaneously pushed to slide upward in the corresponding trapezoidal groove 27, and the clamping plate 216 slides downward, and the position lock of the clamping seat 25 is first released, and then the clamping motor 26, the bidirectional screw rod 24 and the T-shaped slider 23 are cooperated to drive the two groups of clamping seats 25 to move away from each other, and the forged steel support roller is fixed by the cooperation of the upper top 22 and the lower top 18; Step six: The lifting motor 35 drives the lifting screw 34 to rotate. The lifting screw 34 not only drives the annular water shield 31 to rise, but also combines the active sprocket 37, the chain 39 and the driven sprocket 38 to drive the lower top 18 to rotate, and then drives the forged steel support roller to rotate. During the rising process of the annular water shield 31, the forged steel support roller is induction heated by the internal heating coil 32. At the same time, the water suction pump 312 draws cooling water from the water tank 17 and injects it into the water outlet chamber 310 through the water injection hose 313, and then sprays it onto the heated forged steel support roller through a number of water outlet holes 311 for quenching.
