Description

Technical Field

[0001] The invention relates to the technical field of fastener heat treatment processing equipment, in particular to fastener heat treatment equipment. Background Art

[0002] Fasteners are mechanical elements used to connect, fix or support other parts. They are widely used in various machines and equipment to ensure the stability and safety of the structure. As a common fastener, U-clamps have unique structural characteristics and usage scenarios. U-clamps are usually made of metal and are "U" shaped with two parallel legs and a bottom connecting the two legs. This design enables the U-clamp to easily clamp and fix objects of various shapes and sizes. The legs of the U-clamp can be fixed by bolts, nuts or other fasteners to achieve a firm connection to the clamped object.

[0003] When the U-shaped clamp is produced and processed, it needs to be heat treated. Quenching is a very important heat treatment process in the processing of U-shaped clamps. Through quenching and subsequent tempering, the physical and chemical properties of the metal can be greatly improved to meet various practical application needs. During quenching, due to the circular hole on the U-shaped clamp, the surface tension of water makes it difficult for water to enter the circular hole during quenching, resulting in low cooling efficiency in the circular hole. Improvements need to be made to this problem.

[0004] Therefore, it is necessary to design a fastener heat treatment equipment that is highly practical and ensures quenching efficiency. Summary of the invention

[0005] The object of the present invention is to provide a fastener heat treatment device to solve the problems raised in the above background technology.

The output shaft of the driving motor is fixedly connected to a rotating shaft. The top of the rotating shaft is fixedly connected to a working basket. The middle of the working basket is fixedly connected to a partition.

[0009] According to the above technical solution, the water-turning mechanism includes a fixed plate, an electric telescopic rod, a lifting plate, a fixed frame, an elastic water-turning plate and a positioning frame.

[0010] According to the above technical scheme, the auxiliary mechanism includes a lifting rod, a working box, a spring, an inclined plate, an adjusting frame, a moving rod, an arc-shaped push plate, a water storage bag, a water spray pipe and a water suction pipe. The lifting rod is fixedly connected to the middle of the top of the electric telescopic rod, the working box is fixedly connected to the middle of the top of the partition, the spring is fixedly connected to the left side of the working box, the inclined plate is fixedly connected to the right end of the spring, the adjusting frame is fixedly connected to the left side of the inclined plate, the moving rod is rotatably connected to the adjusting frame, the arc-shaped push plate is fixedly connected to the moving rod, the water storage bag is fixedly connected to the bottom of the working basket, the water spray pipe is fixedly connected to the bottom of the right side of the water storage bag, and the water suction pipe is fixedly connected to the inner circle of the top of the water storage bag and is located on the outside of the electric telescopic rod.

[0011] According to the above technical solution, the output shaft of the driving motor passes through the bottom of the body and extends into the body to be fixedly connected to the rotating shaft. A water outlet is provided at the bottom right side of the body, and the water in the body can be discharged through the water outlet.

[0012] According to the above technical solution, the positioning frame is fixedly connected to the inner wall of the working basket on the side away from the elastic water-flipping plate, and the top end of the electric telescopic rod passes through the bottom of the working basket and extends into the working basket to be fixedly connected to the lifting plate, so that the electric telescopic rod can control the lifting plate to rise and fall during work.

[0013] According to the above technical solution, a circular groove is opened in the middle of the bottom of the partition to accommodate the lifting of the jacking rod. The top end of the jacking rod passes through the bottom of the partition and the bottom of the working box and extends into the working box, so that the jacking rod can be lifted and lowered in the working box.

[0014] According to the above technical solution, a one-way valve 1 is arranged at the top of the water suction pipe, and the input end of the one-way valve 1 is the top. A one-way valve 2 is arranged in the interface between the water spray pipe and the water storage bag, and the input end of the one-way valve 2 is the left side. The end of the water spray pipe away from the water storage bag sequentially passes through the bottom right side of the working basket and the top right side of the working basket and extends into the working basket, and the inclined direction is aligned with the arc-shaped push plate, so that the water in the water storage bag can be sprayed out through the water spray pipe.

[0015] According to the above technical solution, the left end of the moving rod passes through the left inner wall of the working box and extends to the left side of the working box and is fixedly connected to the arc-shaped push plate, so that the moving rod can drive the arc-shaped push plate to move, and the electric telescopic rod operates by rising rapidly and falling slowly.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, when the U-shaped clip needs to be quenched, the body is filled with water, and then a plurality of U-shaped clips are put into the working basket together for quenching. At this time, the U-shaped clip falls on the top of the partition, and the driving motor is turned on. When the driving motor is working, the working basket on the rotating shaft is controlled to rotate, so that the water flow can flow in the body, and the impact force of the round hole on the U-shaped clip when it contacts the water is increased;

[0017] The U-shaped clamp during quenching is generally a red casting with high temperature, which is easy to cause the U-shaped clamp to deform under high temperature. In order to prevent the U-shaped clamp from being deformed by collision when placed in the working basket, the electric telescopic rod can be opened when the working basket rotates. The electric telescopic rod controls the lifting plate to rise during operation, and then the elastic water-turning plate is rotated up and down in the positioning frame, so that the water above the elastic water-turning plate can be turned upward, so that the water flow at the bottom of the partition can impact upward, and the U-shaped clamp on the top of the partition can be turned from bottom to top, and the working basket can be rotated to make the U-shaped clamp move obliquely in the partition. When the electric telescopic rod controls the lifting plate to rise, negative pressure is generated in the water storage bag. At this time, the water flow is sucked into the water suction pipe. When the electric telescopic rod controls the lifting plate to move downward, the water storage bag is squeezed, so that the water flow in the water storage bag is sprayed out through the water spray pipe, and the U-shaped clamp near the inner wall of the partition can be pushed to the middle of the top of the working basket to prevent the U-shaped clamp from knocking on the inner wall of the working basket, so as to avoid deformation of the U-shaped clamp caused by knocking;

[0018] When the lifting plate rises, the lifting plate pushes the lifting rod to rise, and the lifting rod moves up and into the working box, so that the lifting rod can squeeze the inclined plate in the working box, so that the inclined plate fits against the outer wall of the lifting rod during squeezing, and at the same time the spring is compressed, so that the inclined plate pushes the arc-shaped push plate to move through the moving rod, so as to avoid the U-shaped clamps approaching the middle and colliding with each other under the action of the centrifugal force in the working basket when the working basket rotates, so as to ensure that the U-shaped clamps will not be deformed in the working basket due to mutual collision, so as to minimize the impact of the collision on the U-shaped clamps when quenching the U-shaped clamps.

[0040] The positioning frame 406 is fixedly connected to the inner wall of the working basket 303 on the side away from the elastic water-turning plate 405. The top of the electric telescopic rod 402 passes through the bottom of the working basket 303 and extends into the working basket 303 to be fixedly connected to the lifting plate 403, so that the electric telescopic rod 402 can control the lifting plate 403 to rise and fall during operation.

[0041] A circular groove is provided in the middle of the bottom of the partition 304 to accommodate the lifting rod 501. The top of the lifting rod 501 passes through the bottom of the partition 304 and the bottom of the working box 502 and extends into the working box 502, so that the lifting rod 501 can be lifted and lowered in the working box 502.

[0042] A one-way valve 1 is arranged at the top of the water suction pipe 510, and the input end of the one-way valve 1 is the top. A one-way valve 2 is arranged in the interface between the water spray pipe 509 and the water storage bag 508, and the input end of the one-way valve 2 is the left side.

[0045] The U-shaped clip during quenching is generally a red casting with high temperature, which is easy to deform under high temperature. In order to prevent the U-shaped clip from being deformed by collision when placed in the working basket 303, the electric telescopic rod 402 can be opened when the working basket 303 rotates. The electric telescopic rod 402 controls the lifting plate 403 to rise during operation, and then the elastic water-turning plate 405 is rotated up and down in the positioning frame 406, so that the water above the elastic water-turning plate 405 can be turned upward, so that the water flow at the bottom of the partition 304 impacts upward, and the U-shaped clip on the top of the partition 304 can be turned from bottom to top.
