Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring processing, in particular to a quenching device for producing fatigue-resistant springs. Background Art
[0002] Quenching means that after a metal workpiece is heated to a certain temperature, it is immersed in a coolant medium. After cooling treatment, the performance of the workpiece is better and more stable. In the production process of springs, the springs need to be heat treated. In the production process of springs, in order to maintain the elasticity of the springs, the springs need to be quenched.
[0003] In the production process of springs, the springs need to be heat treated. Quenching medium is usually used for heat treatment. After the springs are cooled in the quenching medium, the temperature of the quenching medium in the quenching pool will increase with heat transfer. In this case, for other springs to be quenched, the quenching medium will not have a good quenching effect on the springs to be quenched. It is necessary to ensure that the temperature of the quenching medium reaches a fixed required value. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a quenching device for producing fatigue-resistant springs.

[0007] The beneficial effect of adopting the above further scheme is that the quenching box is injected with suitable quenching liquid, the cooling tube is filled with quenching liquid, and the coolant is injected into the cooling box through the liquid inlet pipe. The one-way valve can prevent the quenching liquid from flowing back. After the spring is quenched for a period of time, the temperature of the quenching liquid in the quenching box rises to a range that is not suitable for quenching. At this time, the pump is started to pump the quenching liquid in the quenching box into the cooling tube, and the quenching liquid in the cooling tube will flow into the quenching box, thereby reducing the temperature of the quenching liquid in the quenching box. At the same time, the high-temperature quenching liquid poured into the cooling tube can exchange heat with the coolant, thereby preparing for subsequent quenching work and improving the quenching effect on the spring.
[0008] Furthermore, the cooling pipe includes a plurality of vertically arranged pipes, and a plurality of the pipes are bent, one end of the bottom pipe is connected to the second inlet, one end of the top pipe is connected to the second outlet, and both ends of the middle pipe are connected to one end of the adjacent pipe.
[0009] The beneficial effect of adopting the above further scheme is that the cooling tube of this shape can increase the amount of quenching liquid stored therein, so that more low-temperature quenching liquid can be poured into the quenching box and more high-temperature quenching liquid can be stored, thereby minimizing the temperature of the quenching liquid in the quenching box.

[0011] The beneficial effect of adopting the above further scheme is that after the quenching liquid overflows the position of the infrared transmitter, the infrared light emitted by the infrared transmitter cannot be received by the infrared receiver due to refraction, based on which the user can know the amount of quenching liquid injected into the quenching box.
[0012] Furthermore, a bracket is installed on the top of the quenching box, a pair of connecting plates are installed on the top of the bracket, a rotating shaft is rotatably connected between the pair of connecting plates, a pair of steel wire ropes are wound around the outside of the rotating shaft, a quenching plate is slidably provided inside the quenching box, a pair of connecting strips are installed inside the quenching plate, and the pair of steel wire ropes are correspondingly connected to the pair of connecting strips.
[0013] Furthermore, a motor is installed on the top of the bracket, and the output end of the motor is transmission-connected to the rotating shaft.
[0014] The beneficial effect of adopting the above further scheme is that the springs to be quenched can be placed in the quenching plate, and the motor drives the rotating shaft to rotate, so that the wire rope is wound around it or dropped from it, thereby raising or lowering the quenching plate, which is convenient for users to quench a large number of springs.
[0015] Furthermore, the inner bottom of the quenching plate is provided with a plurality of slots, the tops of the slots are all provided with limiting cylinders, the bottom of the limiting cylinders is provided with through holes, and the outer side of the limiting cylinders is provided with a plurality of holes connected to the through holes.
[0016] Furthermore, the inner bottom of the quenching plate is provided with a plurality of liquid inlet holes.
[0017] The beneficial effect of adopting the above further scheme is that the spring to be quenched can be covered in the limiting cylinder. When the quenching plate is immersed in the quenching liquid, the quenching liquid will flow out through the liquid inlet and holes, thereby quenching the outer wall and inner wall of the spring to improve the quenching effect on the spring.
[0018] The beneficial effect of the utility model is as follows: the utility model obtains a quenching device for producing fatigue-resistant springs through the above-mentioned design, injects suitable quenching liquid into the quenching box, fills the cooling pipe with quenching liquid, and injects coolant into the cooling box through the liquid inlet pipe at the same time, and the one-way valve can prevent the quenching liquid from flowing back. After the spring is quenched for a period of time, the temperature of the quenching liquid in the quenching box rises to a range that is not suitable for quenching. At this time, the pump is started to pump the quenching liquid in the quenching box into the cooling pipe, and the quenching liquid in the cooling pipe will flow into the quenching box, so as to reduce the temperature of the quenching liquid in the quenching box, and at the same time, the high-temperature quenching liquid poured into the cooling pipe can exchange heat with the coolant, so as to prepare for the subsequent quenching work and improve the quenching effect on the spring.
