Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the drawings:

[0033] The camshaft flame quenching automatic heat treatment machine tool of the present invention includes a feeding mechanism 1, a rotating mechanism 2, a heating mechanism 3, a cooling mechanism 4, and a control mechanism sequentially arranged on the machine tool. The control mechanism controls the coordinated operation of the various mechanisms of the machine tool. The specific structure is as figure 1 , figure 2 , image 3 , Figure 4 Shown.

[0034] The feeding mechanism 1 of the present invention includes a sliding groove 1-1 and a feeding catcher 1-4. The function of the feeding mechanism 1 is to make the camshaft enter the rotating mechanism 2 in the required time and sequence. The slide chute 1-1 is arranged on the frame of the machine tool. The slide chute 1-1 has an upper arc structure or a straight structure. The slide chute 1-1 is composed of corresponding guid...

Abstract

The invention relates to a cam shaft flame hardening automatic heat treatment machine tool. The machine tool comprises a feeding mechanism, a rotating mechanism, a heating mechanism, a cooling mechanism and a control mechanism controlling all the mechanisms of the machine tool to run cooperatively, wherein the feeding mechanism, the rotating mechanism, the heating mechanism, the cooling mechanism and the control mechanism are arranged on the machine tool in sequence. The invention further discloses a cam shaft flame hardening automatic heat treatment technology. The technology specially comprises the steps of automatic feeding, flame heating and cooling. By the adoption of the cam shaft flame hardening automatic heat treatment machine tool and technology, the technical problem of conducting automatic heat treatment on a cam shaft with the flame hardening heat treatment technology is solved, automatic precise operation is achieved during cam shaft flame hardening, hardening quality and stability are guaranteed, a feeding system and a discharging system of the cam shaft flame hardening automatic machine tool are high in automation degree, and production efficiency and economic effectiveness are further improved.

Description

Technical field [0001] The invention relates to the technical field of heat treatment, in particular to a machine tool and process for flame quenching automatic heat treatment of shaft parts. Background technique [0002] The camshaft is a key component in a piston engine. The main body is a cylindrical rod with approximately the same length as the cylinder group. There are several cams on it to drive the valve and control the opening and closing of the valve. The camshaft in the engine has a high speed and needs to withstand a large torque, but also needs to withstand periodic shock loads. The contact stress between the cam and the tappet is very high, and the relative sliding speed is also very high, so the wear of the cam working surface is more serious. In view of this situation, the camshaft journal and cam working surface should have higher dimensional accuracy, smaller surface roughness and sufficient rigidity, as well as higher wear resistance and good lubrication. Ther...
