Embodiment 1

[0063] A quenching system for auto parts, wherein, such as figure 1 As shown, it includes: a base 1, a telescopic mechanism 2, a drop hopper 3, a flame heating mechanism 4, a thermal insulation transmission mechanism 5, and a quenching box 6.

[0064] The telescopic mechanism 2 is installed on the left side of the base 1 , and the right side of the telescopic mechanism 2 has a telescopic end 21 .

[0065] The blanking hopper 3 is installed on the base 1, and the blanking hopper 3 is located on the right side of the telescopic mechanism 2. The bottom of the blanking hopper 3 has a through opening (not shown), and the through opening runs through the left and right sides of the bottom of the blanking hopper 3. The through opening and the telescopic end 21 Correspondingly, the shape and size of the through opening and the connecting rod H1 are adapted to each other.

[0066] Such as figure 1 , 3 , 4, and 6, the fire-spraying heating mechanism 4 is installed on the base 1, an...

Abstract

The invention discloses a quenching system and method of an automobile accessory and relates to the technical field of quenching. The quenching system of the automobile accessory comprises a base, anextending and retracting mechanism, a material falling hopper, a flame spraying heating mechanism, a heat preservation conveying mechanism and a quenching box. The flame spraying heating mechanism isprovided with a material opening, a heating space, an annular gear, a power device, a bevel gear, a flame spraying column, a connection block, a spring, an electromagnetic sheet and a threaded cylinder. According to the quenching system, the annular gear drives the bevel gear to rotate, the flame spraying column is driven to rotate in and rotate out in the threaded cylinder so that the distance between the flame spraying column and the connection rod is controlled; when the distance between the flame spraying column and the connection rod is controlled, the manners that the electromagnetic sheet attracts the connection block and the spring resets the connection block can be adopted to enable the flame spraying column to be disengaged from and connected with the bevel gear at any time, andthen the adjustment of rotating in and rotating out a part or the whole of the flame spraying column according to the shape of the connection rod can be freely achieved; and in this way, the connection rod can obtain a uniform appropriate quenching layer in the heating process, and the physical performance of the connection rod finished product is improved.

Description

technical field [0001] The invention relates to the field of quenching technology, in particular to a quenching system for auto parts. Background technique [0002] The quenching of steel is to heat the steel to the critical temperature Ac 3 (hypoeutectoid steel) or Ac 1 (Hypereutectoid steel) above the temperature, keep it warm for a period of time to make it fully or partially austenitized, and then quickly cool it below Ms (or isothermal near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite). Tensitic) transformation heat treatment process. [0003] Based on the phase transformation critical point of steel, it is necessary to heat above the phase transformation temperature during heating and quenching to form fine and uniform austenite grains, and obtain fine martensite structure after quenching. However, if the heating temperature is too high and the proeutectoid cementite dissolves too much, or even completely dissolves, ...
