Description

Technical Field

[0001] The invention relates to the technical field of leaf spring heat treatment, in particular to a quenching device for producing vehicle leaf springs. Background Art

[0002] The existing quenching pool is designed to have a large volume. The quenching pool must be filled so that the leaf spring can be completely immersed. This not only causes a certain amount of waste, but also is not conducive to the flexible fine-tuning of the quenching liquid composition. The leaf spring requires manual loading and unloading. A quenching equipment for leaf springs with application number CN202011326097.7 includes a gantry bracket, a flip-type quenching container, a quenching container rotating device and a leaf spring feeding cart, which can be used for automatic quenching operations of leaf springs, reduces labor intensity and occupies a small area, which is convenient for the production of small batches or test pieces.

[0003] Although the device has the above advantages, it still has the following defects in actual use:

[0004] 1) When clamping the leaf spring, the positions of the left and right vertical rods are relatively stable, but there is a length difference between the springs of the same group of leaf springs, resulting in poor clamping effect for the springs of the same group;

[0005] 2) After quenching, the device resets the leaf spring by opening the quenching container downward. However, the quenching liquid remaining in the quenching container is easy to drip and cause pollution, or the leaf spring is unloaded after the quenching liquid is completely drained, which is easy to reduce the heat treatment efficiency;

[0006] 3) The feed cart and quenching container of the device are connected by an anti-detachment hook, but the connection of the hook requires manual operation, and the temperature around the leaf spring after heat treatment is high, which can easily scald the operator and pose a safety risk.

[0048] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 1 , Attachment Figure 5 ;

[0049] The ball 47 is provided with a positioning unit 48 on the outside. The positioning unit 48 is provided on both sides of the top of the vertical plate 41 so that the ball 47 can be positioned when it moves in both directions.

[0050] The outer surface of the pressure ring 483 is fixedly connected to a fixing ring 485, which plays a supporting and limiting role. The outer surface of the fixing ring 485 is fixedly connected to the inside of the groove 481. The outer surface of the magnetic plate 482 is fixedly connected to a connecting rod 486.

[0051] By setting up the positioning unit 48 and utilizing the magnetic repulsion between the ball 47 and the magnetic plate 482, the magnetic plate 482 is caused to descend and abut against the pressure ring 483. Thus, the position of the ball 47 can be monitored through the pressure exerted on the pressure ring 483, so as to facilitate the connection between the ball 47 and the slot 49, thereby avoiding manual operation for connection and preventing the operator from being burned.

[0052] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0053] When working; first, according to the size and number of the synchronous leaf spring reeds, the knob rod 15 is used to drive the rotating column 12 to rotate, so that the spiral groove 13 follows the rotation and is connected with the corresponding internal part of the sleeve 6 from bottom to top. When the spiral groove 13 is connected with the sleeve 6, the external air pumping device is connected to the air core tube 14, so that the external air is pumped into the interior of the sleeve 6, so that the air pressure pushes the push plate 7 to slide, thereby driving the clamping plate 11 to move through the action of the slide bar 8 and the connecting plate 10, so that the distance between the clamping plates 11 on both sides is adapted to the size of the leaf spring reed, and then the two ends of the reed are respectively placed between each group of upper and lower clamping plates 11 for clamping, and then the same group of reeds are clamped from long to short, and each group of clamping plates 11 on the fixed sleeve 5 is clamped from bottom to top. After the clamping is completed, the reed can be sent to the heating furnace through the bottom plate 2 for heating and bending to shape, and then it can be taken out;

[0054] The bottom plate 2 after being taken out carries the spring sheet and is between the gantries 445 on both sides. Then the linear motor 447 slides along the slide rail 446, so that the winding motor 441, the rotating rod 442 and the drum 443 drive the ball 47 to translate through the cable 43, so that the cable 43 enters the inside of the connecting groove 45, and the ball 47 enters the inside of the translation groove 46. When the ball 47 is aligned with the card slot 49 up and down, the winding motor 441 winds the cable 43 through the drum 443, so that the ball 47 rises and forms a card connection with the card slot 49. By winding the cable 43 again, the bottom plate 2 and the spring sheet are lifted and lifted, and then the linear motor 447 moves the two to the top of the quenching box 1.

[0055] When the ball 47 moves and aligns with the magnetic plate 482 up and down, the magnetic plate 482 is pressed down into the groove 481 by the action of magnetic repulsion, and the connecting rod 486 drives the card plate 487 to move synchronously. When the magnetic plate 482 applies pressure to the pressure ring 483, the resistance of the pressure ring 483 itself changes, thereby changing the current value of the circuit. Through the change in the current value, the PLC control circuit monitors the change in the circuit of the pressure ring 483 to form a positioning signal, and sends it through a signal transmitting device, and receives the positioning signal through a signal receiving device of an external control circuit, so as to obtain the relative horizontal position and relative height of the ball 47, which can facilitate the control of the movement of the ball 47, so that the length of the ball 47 to continue to move is the same as the distance between the card slot 49 and the groove 481, so that the ball 47 moves to the inside of the translation slot 46 and is located directly below the card slot 49, so as to facilitate the precise docking of the ball 47 with the card slot 49;

[0056] When the bottom plate 2 drives the spring to move to the top of the quenching box 1, the motor 36 is adjusted to drive the screw 35 to rotate according to the size and speed of the spring, so as to drive the two side baffles 31 to slide and adjust the spacing through the slider 34 to provide a suitable quenching space. Then the external feeding equipment adds the quenching liquid into the interior of the quenching box 1 through the material pipe, and makes the quenching liquid between the two side baffles 31, and then the drum 443 releases the cable 43, so that the bottom plate 2 descends into the interior of the quenching box 1, and the bottom plate 2 is supported by a group of clips 32 below. After quenching is completed, the bottom plate 2 is lifted and lifted, and the quenching liquid on the bottom plate 2 is completely dripped into the interior of the quenching box 1 through a certain shaking action to the left and right. Then, the bottom plate 2 and the leaf spring are moved to the ground on the side of the quenching box 1 by transportation, and then the spring can be disassembled.

[0057] Although 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 appended claims and their equivalents.
