Description

Technical Field

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

[0002] Screws are mostly used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. The screw and barrel are the core components of plastic molding equipment. They are the parts that heat, extrude and plasticize, and are the core of plastic machinery. The screw needs to be heat treated during production. The heat-treated screw is immersed in the oil in the quenching tank to obtain quenching cooling.

[0003] After searching, a screw heat treatment equipment disclosed in the Chinese patent authorization announcement number CN 203728887 U includes a fan, a tank body, a reduction motor, a baffle, a hydraulic cylinder, a support plate and a frame body. The left end of the tank body is equipped with a fan, and the right end is equipped with two hydraulic cylinders. The hydraulic cylinders are provided with support plates, which are connected to the frame body. Although the equipment can process a large number of screws at the same time, since the area of ​​the frame body for storing the screws immersed in the tank body is fixed, it is difficult for the screws in the frame body to uniformly contact the oil in the tank body, and the quenching cooling speed of the screws is relatively slow, which affects the working efficiency of the screw heat treatment. Therefore, we propose a screw heat treatment equipment. Utility Model Content

The cross-sectional shape of the liquid through holes 904 is rectangular, so that when the carrier plate 9 is immersed in the oil in the quenching tank 1, the oil can quickly penetrate the carrier plate 9 through each liquid through hole 904.

[0024] As a preferred implementation in this embodiment, Figure 2 As shown, a bearing seat 301 is fixedly installed on the inner side of the transverse guide rail 3, and the bearing seat 301 is rotatably connected to the end of the screw shaft 501, thereby achieving the purpose of ensuring the rotation stability of the screw shaft 501.
