Description

Technical Field

[0001] The present invention belongs to the technical field of automotive bolt quenching, and specifically relates to a quenching device for the production of automotive bolts. Background Technique

[0002] As a core component of mechanical connection, the strength and durability of bolts directly affect the safety and reliability of the automotive structure. High-strength bolts need to achieve the balance of surface hardness and core toughness through the quenching process, and the cooling uniformity and efficiency during the quenching process are the key factors determining the product quality. Therefore, a quenching device is required to quench automotive bolts.

[0003] When the existing quenching equipment quenches automotive bolts, long-term quenching will cause the temperature of the coolant to rise, reducing the cooling efficiency. Moreover, the existing coolant is in a static state during quenching, which will cause the accumulated heat to be effectively dissipated, resulting in the accumulation of heat and affecting the quenching effect. In addition, when loading automotive bolts of different heights, the height-limiting component cannot be set in time according to the requirements of the bolts, and there is a probability that the bolts will deviate during transportation.

[0004] It is necessary to improve the efficiency of the device for quenching automotive bolts, avoid the deviation of the bolt transportation position by setting a height-limiting component, and ensure the automation of the device by automatically grasping the processed materials, thereby improving the quenching effect of the device for automotive bolts used by users.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] Through the cooperation of structures such as the mounting seat, the first limiting rod, and the mounting disc, when the device needs to replace the height limiting block of different heights to limit the height of the bolt, by pressing the height limiting block, the limiting block moves downward and approaches the limiting disc, and contracts inward when passing through the limiting disc, and the limiting block is reset by the first return spring to push up the limiting disc, so that the limiting disc contacts the mounting disc. At this time, pulling the height limiting block can remove and replace the height limiting block. Further, by pressing the height limiting block, the mounting disc enters the inside of the limiting groove, and the mounting disc contacts the limiting block, and the limiting block contracts inward. After the limiting block passes through the mounting disc, the first return spring resets the limiting block, and then the height limiting block is integrally limited by the limiting block located at the bottom of the mounting disc, so as to quickly replace the height limiting block, thereby achieving the purpose of facilitating the device to quickly adapt to the quenching feeding of automotive bolts of different specifications.

[0020] Through the cooperation of structures such as the second delivery pipe, the transmission disc, and the transmission paddle, when the high-frequency heating ring quenches the automotive bolts being conveyed inside the conveying table, the conveying pump is started to convey and spray the quenching liquid inside the quenching cylinder, and it is sprayed on the surface of the automotive bolts through the spray heads. By adjusting the opening and closing of the solenoid valves at both ends of the second delivery pipe and the first delivery pipe, the flow direction of the water can be controlled, so that it can be completed that only two spray heads are used for spraying when starting the conveying pump, or controlling a single spray head for spraying, and the flow direction drives the transmission paddle to rotate forward or backward, and then drives the vibrating head to continuously contact the outer wall of the quenching cylinder to drive the quenching cylinder to vibrate, thereby preventing uneven contact between the automotive bolts and the quenching liquid during quenching, and further improving the quenching effect, so as to achieve the purpose of facilitating the device to improve the quenching effect on automotive bolts and quickly cooling them.

[0021] The present invention arranges the coordination of structures such as a connecting rope, a connecting block, and a first gear, so that after the material collection barrel collects a specified amount of automobile bolts, the device can start the first motor to drive the first gear to rotate and then drive the second gear to rotate, so that the first clamping arm and the second clamping arm shrink and approach to lift the entire material collection barrel for unloading, thereby achieving the purpose of facilitating the device to quickly unload the quenched automobile bolts.

[0022] The present invention arranges the cooperation of the second motor, the first connecting rod, the stirring rod and other structures, so that when the automobile bolt enters the material taking barrel and contacts the quenching liquid, the second motor is started to drive the first connecting rod and the stirring rod to rotate, thereby stirring the coolant inside the quenching barrel, avoiding the problem of heat accumulation leading to reduced quenching efficiency. The angle of the spray head is opposite to the material taking barrel, so that the quenching liquid can be recovered after quenching the automobile bolt, thereby achieving the purpose of improving the quenching efficiency of the device.
