Description

Technical Field

[0001] The invention relates to the technical field of quenching oil tanks, in particular to a push-plate type quenching oil tank. Background Art

[0002] The quenching oil tank is a kind of equipment used for quenching, which is mainly used for quenching various mechanical parts and workpieces in quenching oil of the temperature required by the process. Among them, the push-plate quenching oil tank adopts a double-station closed underwater transfer, and a small amount of nitrogen can be introduced to ensure that the parts complete the entire quenching process without contact with the air. The quenching sealed chamber does not need to open the door, which avoids the contact between the furnace gas and the air and the furnace gas fluctuation caused when the quenching sealed chamber door is opened. The existing quenching oil tank consists of a main quenching tank, an auxiliary oil tank, a quenching lifting platform, a discharging lifting platform, an oil push mechanism, a quenching oil agitator, a fault inspection door, a peephole, an oil heater, a heat exchanger, a quenching oil level controller, an automatic oil replenishing device, a temperature control device, etc. The outer wall of the oil tank above the ground is provided with an insulation layer.

[0003] The traditional push-plate quenching oil tank lowers the workpiece to the quenching station in the oil tank through the feed lifting mechanism. After quenching, the workpiece is transferred from the quenching station to the discharge lifting mechanism station, so that the quenched workpiece can be automatically fed and unloaded. However, in the quenching process, for the workpiece with a notch on the outside, when the notch is facing upward during quenching, impurities generated by quenching will remain inside the notch. After the workpiece is discharged, the impurities inside the notch need to be cleaned, which brings certain troubles to the subsequent quenching process. Summary of the invention

[0102] The principle and advantages of push plate quenching oil tank:

[0103] First, when loading the workpiece through the workpiece fixing frame 100, the workpiece is fixed inside the workpiece fixing frame 100 by means of a clamp or bolts to prevent it from loosening during subsequent movement and flipping. When the workpiece is moved from the heat treatment furnace to the station where the feed lifting mechanism 11 is located, the workpiece fixing frame 100 is lifted and lowered to the quenching station inside the oil tank sealing chamber 1 by the feed lifting mechanism 11. At this time, the quenching station is corresponding to the transition component 3, and then the workpiece fixing frame 100 is directly lowered into the support frame 36 by the feed lifting mechanism 11, and the workpiece fixing frame 100 is automatically engaged and fixed by the fixing component 5; when quenching is completed, the motor 47 at the top of the oil tank sealing chamber 1 is started to drive the chain B45 to rotate, so that the chain B45 drives the sprocket C44 to rotate through the sprocket D46, and the sprocket C44 drives the corresponding two sprockets B42 in the two groups of sprockets B42 to rotate through the connecting shaft 43, and the two Each connecting shaft 43 is rotatably connected to the top of the transition platform 2 through the bearing seat 21, so that the chain A41 drives the push plate 31 to slide along the top of the transition platform 2, and moves the quenched workpiece to the discharging lifting mechanism 12 station to prepare for discharging; it is worth noting that when the chain A41 is in transmission operation, its lower half drives the support plate 32 to move horizontally through the connecting piece 33, so that the support plate 32 drives the push plate 31 to slide on the top of the transition platform 2, and at the same time, the upper half of the chain A41 is reversely transmitted, and under the limiting action of the pressure plate 23, the chain A41 is prevented from slipping with the sprocket A35 due to relaxation, thereby improving stability, so that the chain A41 drives the sprocket A35 to rotate, and then drives the rotating plate frame 34 to rotate through the sprocket A35, so that the rotating plate frame 34 drives the workpiece fixing frame 100 inside the support frame 36 to flip, so as to automatically clean the impurities inside the slot during the transition movement of the workpiece.

[0104] Its advantage is that it can automatically drive the workpiece inside the support frame 36 to rotate during the movement of the push plate 31, so as to clean the impurities of the workpiece located in the groove, and the cleaning effect can be improved while moving and rotating; when the cleaning is completed, the support frame 36 can be rotated to the initial state, and at this time the workpiece fixing frame 100 inside the support frame 36 is just located at the work station of the discharge lifting mechanism 12, so as to facilitate the discharge after quenching.

[0105] When the fixing assembly 5 in the push-disk quenching oil tank of the present application fixes the workpiece fixing frame 100, the frame limit plate 101 on the outside of the workpiece fixing frame 100 will be aligned with the wedge-shaped block A51 and the wedge-shaped block B52 on the inside of the support frame 36. As the workpiece fixing frame 100 is lowered and placed on the top of the bottom frame 361, the slide groove 102 at the bottom of the frame limit plate 101 slides on the outside of the wedge-shaped block A51 and the wedge-shaped block B52 until the top of the slide groove 102 is aligned with the wedge-shaped block A51 and the wedge-shaped block B52. The inclined surfaces 52 are pressed against each other, so that the two wedge-shaped blocks A51 move away from each other. At this time, the two wedge-shaped blocks A51 push the tooth plate A54 and the tooth plate B55 away from each other through the connecting plate A53, and one of the connecting plates A53 cooperates with the right-angle plate 38 on the outside of the support frame 36 to compress the outer spring 57. At the same time, the tooth plate A54 drives the slide plate 58 to slide at the bottom of the wedge-shaped block B52, so that the slide plate 58 drives the sliding pin 52 at the bottom of the wedge-shaped block B52 through the inner limiting hole 59. 2 moves, so that the sliding pin 522 drives the sliding rod 521 on the outer side of the wedge-shaped block B52 to slide on the inner side of the sliding sleeve 39, and the sliding sleeve 39 is fixed to the outer side of the support frame 36 through the fixing plate 363, so that the wedge-shaped block A51 drives the wedge-shaped block B52 to slide synchronously. When the wedge-shaped block A51 and the wedge-shaped block B52 move to the position of the slot 103 respectively, the workpiece fixing frame 100 is located at the top of the bottom frame 361. Since there is an assembly space between the inner side of the slot 103 and the wedge-shaped block A51 and the wedge-shaped block B52, The gap can make the wedge-shaped block A51 and the wedge-shaped block B52 automatically engage with the inner side of the slot 103 under the action of the spring 57, so as to realize the engagement and fixation of the workpiece fixing frame 100; it is worth mentioning that when the support frame 36 drives the workpiece fixing frame 100 to flip, the reinforcement plate A37 fixedly connected to the outside of the angle steel 362 and the reinforcement plate B310 fixedly connected to the top of the sliding sleeve 39 can respectively reinforce the tooth plate A54 and the tooth plate B55 as well as the wedge-shaped block B52 to ensure the stability of the structure.

[0106] It is worth mentioning that the above fixing method has the following advantages:

[0107] Advantage 1: One of the wedge-shaped clamping blocks A51 can automatically extend and slide after being squeezed by the workpiece fixing frame 100, and at the same time, it can drive the other wedge-shaped clamping block A51 to extend and slide, thereby achieving the clamping and fixing of two sides of the workpiece fixing frame 100.

[0108] Advantage 2: When the two wedge-shaped blocks A51 are squeezed and moved by the workpiece fixing frame 100, the wedge-shaped blocks B52 on the other two sides will follow and move, so as to fix the other two sides of the workpiece fixing frame 100, improve the fixing effect, and ensure the stability of the workpiece fixing frame 100 during rotation.

[0109] Advantage three, when the support frame 36 rotates and moves to the work station corresponding to the discharge lifting mechanism 12, the support frame 36 drives the roller 512 to approach the reset assembly 6, so that the reset assembly 6 pushes the push rod 511 to slide on the inner side of the support frame 36 through the roller 512, and the push rod 511 drives the tooth plate A54 to slide through the connecting plate B510. At this time, the tooth plate A54 pushes the connecting plate A53 to compress the spring 57, and drives the wedge block A51 to disengage from the inside of the slot 103. At the same time, the wedge block A51 drives the wedge block B52 to disengage from the inside of the slot 103, so that the discharge lifting mechanism 12 can discharge the workpiece fixing frame 100.

[0110] In actual application, the reset component 6 pushes the roller 512 in the following way: when the push plate 31 drives the support frame 36 to translate, the support frame 36 drives the workpiece fixing frame 100 to move toward the side close to the reset component 6, and at this time, the support plate 32 drives the vertical plate 63 to move synchronously through the connecting plate C61, and at this time, the slider 62 at one end of the connecting plate C61 is slidably installed on the inner side of the slide hole 24 to ensure the stability of the movement, and when the roller 512 starts to rotate from bottom to top during the last circle of rotation, the abutting plate 66 on the outer side of the vertical rail plate B653 contacts the baffle 25, and at this time, the support plate 32 continues to move forward, thereby causing the support plate 32 to drive the vertical plate 63 to slide on the outer side of the limit rod 64, so that the outer side of the support frame 36 The distance between the roller 512 and the vertical rail plate B653 is reduced. At the same time, as the support frame 36 rotates, the distance between the arc rail plate 651 and the rotation center of the roller 512 is reduced, and then becomes smaller than the rotation radius of the roller 512, thereby achieving an extrusion effect on the roller 512, so that the roller 512 pushes the push rod 511 to release the engagement effect of the wedge block A51 and the wedge block B52; and when the support plate 32 moves in the opposite direction to the work station corresponding to the feed lifting mechanism 11, the support frame 36 drives the roller 512 to rotate in the opposite direction for reset. At this time, the vertical plate 63 and the clamping plate 66 are both away from the baffle 25. At this time, during the rotation of the roller 512, the limit assembly 65 can be pushed to automatically reset, thereby achieving the continuous use function.

[0111] It is worth mentioning that the above-mentioned promotion method has the following advantages:

[0112] Advantage 1: driven by the push plate 31, the reset assembly 6 approaches the baffle 25 to trigger the reset action of the reset assembly 6, so that the support frame 36 can automatically release the clamping fixation of the internal workpiece fixing frame 100 after rotating for several cycles, so as to facilitate the subsequent unloading work.
