Description

Technical Field

[0001] The invention relates to the technical field of sprocket processing, in particular to a quenching device for sprocket processing. Background Art

[0002] A sprocket is a wheel with cog-type sprocket teeth, which can mesh with the block by using the pitch of the link chain or the pitch of the cable. Sprockets are widely used in the fields of chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries. Sprockets need to be high-frequency quenched during processing. The purpose of sprocket quenching is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools.

[0017] 1. During the use of the present invention, the protruding part of the sprocket body transported on the conveyor belt is picked up under the clamping drive of the clamping cylinder on the output end clamping claw. Thereafter, under the transmission of the pen-shaped cylinder to the output end driving rack, the upper teeth on the upper plane of the middle part of the driving gear are engaged with the circumferential gear teeth of the driven gear, driving the shaft rod inside the bearing seat to rotate, thereby driving the clamping cylinder to flip, and placing the sprocket body on the rotating end head at the end of the support plate.

[0018] 2.

The quenching work is completed in conjunction with the subsequent water immersion cooling, so that the sprocket body meets the corresponding hardness requirements.

[0019] 3. During the use of the present invention, after the sprocket body is placed on the end head, the user operates the receiving assembly in the open state through the handle to complete the closing.

The transmission gear 1103 is rotatably installed at the bottom of the end of the support plate 1102, and the circumferential gear teeth of the transmission gear 1103 are meshed with the side teeth 10. The top of the transmission gear 1103 is coaxially connected with the end 1104, and the transmission gear 1103 is rotated to the sprocket body through the end 1104. The receiving assembly 11 also includes a slide groove 1105, a lock groove 1106, a rocker arm 1107 and a handle 1108. A slide groove 1105 is provided on the left side of the top of the body 1101, and a "U"-shaped structure lock groove 1106 with an opening on the right side is provided on the right side of the top of the body 1101. A rocker arm 1107 is provided inside the body 1101, and a handle 1108 is fixedly installed on the middle end of the top of the rocker arm 1107. The receiving assembly 11 also includes an ear shaft 1109, a locking pin 1110 and an insertion pin 1111. The root of the rocker arm 1107 is fixedly installed with an ear shaft 1109, and the ear shaft 1109 is clearance-matched with the slide groove 1105. A locking pin 1110 is fixedly installed in the middle of the rocker arm 1107, and the locking pin 1110 is slidingly matched with the lock groove 1106. An insertion pin 1111 is provided at the end of the rocker arm 1107, and the insertion pin 1111 is plug-matched with the middle hole of the protruding part of the sprocket body.

[0033] The specific operation is as follows.

First, the rocker arm 1107 is rotated and closed in the slide groove 1105 on the left side of the body 1101 through the root ear shaft 1109, and the rocker arm 1107 is pushed to slide in the slide groove 1105, and the locking pin 1110 in the middle of the rocker arm 1107 is inserted into the open locking groove 1106 on the right side of the body 1101 to complete self-locking. At this time, the insertion pin 1111 at the end of the rocker arm 1107 is inserted into the middle hole of the protruding part of the sprocket body, so that the sprocket body remains stable when driven by the end head 1104 to rotate at high speed, which solves the shortcomings of the prior art that the sprocket body needs to be manually supported and then the quenching equipment drives the sprocket to rotate for quenching, maintains the stability of the sprocket body during high-speed rotation, and prevents the sprocket body from being separated due to centrifugal force and causing production accidents, and has stronger applicability.

[0034] In summary, when the sprocket processing quenching device is used, the protruding part of the sprocket body transported on the conveyor belt is picked up under the clamping drive of the clamping cylinder 705 on the output end clamping claw 706. Thereafter, under the transmission of the pen-shaped cylinder 707 on the output end driving rack 8, the upper teeth 9 on the upper plane of the middle part of the driving gear are engaged with the circumferential gear teeth of the driven gear 704, thereby driving the shaft rod 703 located inside the bearing seat 702 to rotate, thereby driving the clamping cylinder 705 to flip over, and placing the sprocket body on the rotating end head 1104 at the end of the support plate 1102. Through the arrangement of the sprocket feeding assembly 7, the sprocket body can be automatically picked up from the conveyor belt and flipped for feeding, thereby avoiding the repeated labor of manually picking up the sprocket body and placing it on the quenching equipment, and lifting the sprocket body. The continuous quenching feeding efficiency is improved, and compared with the rotary cylinder widely used in the prior art, it is more stable, reliable and more flexible in application. After the sprocket body is placed on the end head 1104, the user operates the receiving assembly 11 in the open state through the handle 1108 to complete the closing. First, the rocker arm 1107 rotates and closes in the slide groove 1105 on the left side of the body 1101 through the root ear shaft 1109, and pushes the rocker arm 1107 to slide in the slide groove 1105, and inserts the locking pin 1110 in the middle of the rocker arm 1107 into the open locking groove 1106 on the right side of the body 1101 to complete self-locking. At this time, the insertion pin 1111 at the end of the rocker arm 1107 is inserted into the middle hole of the protruding part of the sprocket body, so that the sprocket body is driven by the end head 1104. The sprocket wheel keeps stable when rotating at high speed, which solves the deficiency of the prior art that the sprocket wheel body needs to be manually supported and then driven by the quenching equipment to rotate the sprocket wheel for quenching. The stability of the sprocket wheel body when rotating at high speed is maintained, and the production accident caused by the separation of the sprocket wheel body due to centrifugal force is prevented. The applicability is stronger. The upper teeth 9 are arranged on the upper plane of the middle part of the driving rack 8, and the side teeth 10 are arranged on the left side of the end of the driving rack 8. Therefore, the present application only needs to use one pen-shaped cylinder 707 as the power source. On the one hand, the meshing of the upper teeth 9 with the driven gear 704 can drive the sprocket wheel feeding assembly 7 to realize the automatic flipping and feeding of the sprocket wheel body. On the other hand, the meshing of the side teeth 10 with the transmission gear 1103 can also realize the sprocket wheel body through the end head 1104. Rotational transmission, the outer part of the sprocket body is surrounded by an electric heating inductor 5 with a hollow ring structure, so that when the AC generator 3 passes high-frequency AC to the terminal electric heating inductor 5 through the hollow copper tube 4, an induced current of the same frequency is formed on the surface of the sprocket body, and uniform and rapid heating is achieved through the rotation of the sprocket body. After the quenching of the sprocket body is completed, the support plate 1102 no longer supports the sprocket body under the control of the electromagnetic valve, and the sprocket body falls into the water tank 1 under the action of gravity and completes the quenching work through immersion cooling, so that the sprocket body reaches the corresponding hardness requirement. The sprocket needs to be high-frequency quenched during processing. The purpose of quenching the sprocket is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures.To greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel, so as to meet the different use requirements of various mechanical parts and tools.
