Description

Technical Field

[0001] The utility model relates to the technical field of hammer production and processing, in particular to a quenching device for hammer production. Background Art

[0002] A hammer is a tool used to strike an object to move or deform it. It is most commonly used to hammer nails, correct or knock objects open. Hammers come in a variety of forms, the most common of which is a handle and a top. Common hammers include wooden handle ball peen hammer, British fiber handle ball peen hammer, American fiber handle ball peen hammer, bleached handle American ball peen hammer, claw hammer, steel pipe handle claw hammer, American fiber handle claw hammer, British conical claw hammer and fitter's hammer.

[0003] Hammers need to be quenched during production. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of the steel. Most of the existing quenching is to directly place the hammer inside the quenching pool. A large amount of iron filings will be generated when quenching inside the quenching box. The next time other hammers are quenched, the iron filings will adhere to the outer surface of the hammer, affecting the efficiency of hammer production. In addition, the existing quenching device has low quenching efficiency and long time.

[0004] For example, a quenching device for hammer production disclosed in Chinese patent CN213388786U can control the cylinder to drive the pneumatic telescopic rod to extend, so that the storage frame enters the interior of the quenching pool, and then respectively control the first reduction motor and the second reduction motor, the first reduction motor drives the storage frame to rotate slowly inside the quenching pool, the second reduction motor drives the rotary head to rotate, the rotary head drives the cam to rotate, so that the cam slowly reciprocates and hits the buffer pad, and the quenching pool is vibrated through the action of the spring and the telescopic column, and the quenching liquid inside the quenching pool is shaken, and the flow of the quenching liquid is accelerated, thereby improving the quenching efficiency, and the four sides of the storage frame are provided with filter screens, and a frame door is hingedly installed on one of the filter screens, a handle is provided on the surface of the frame door, and a locking member is provided on one side of the frame door, so that the iron filings generated during quenching can be effectively prevented from entering the interior of the quenching liquid to prevent it from affecting the next quenching.

[0005] However, when the device is used, the hammer is directly placed in the storage frame. Since the hammer contacts the bottom of the storage frame, the lower surface of the hammer contacts the quenching liquid unevenly, which affects the quenching quality of the hammer.

[0006] For this reason we urgently need to provide a kind of hammer production quenching device. Utility Model Content
