Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, the metal core mold preheating machine 1000 in this embodiment is a two-station core mold preheating machine, including a main body 1100, the main body 1100 includes a rail frame 1110 and a positioning frame 1120, and the positioning frame 1120 is symmetrical to the rail frame 1110 axis, symmetrically arranged on both sides of the track frame 1110, ( figure 1 One side spacer 1120 is not shown).

[0033]The positioning frame 1120 is L-shaped, including a side frame 1121 and a main frame 1122 perpendicular to the side frame 1121. The side frame 1121 is positioned at one side of the main frame 1122. The height of the main frame 1122 is higher than that of the side frame 1121. The side frame 1121 is fixed by The sheet 1123 is fixed on the ground, and the main frame 1122 is fixed on the ground through the fixing piece 1124 . The track frame 1110 is in a font shape and is located on the other side of the main frame 1122. The length ...

Embodiment 2

[0053] Such as Figure 5 As shown, the structure of the metal mandrel preheater in this embodiment is basically the same as that of the metal mandrel preheater 1000 in Embodiment 1, the difference is that the metal mandrel preheater in this embodiment uses three claws The chuck 2300 and the rotating shaft 2340 replace the rotating mechanism 1300 in the first embodiment to realize the positioning and rotation of the mandrel 2900 .

[0054] The three-jaw chuck 2300 includes a chuck body 2310 , a positioning claw 2320 , an adjusting nut 2330 and a rotating shaft 2340 . The chuck main body 2310 is a cylinder, and there are three positioning claws 2320, which are rectangular parallelepiped. The positioning claws 2320 are connected to the chuck main body 2310, and are evenly distributed around the axial direction of the chuck main body 2310. The positioning claws 2320 protrude from the chuck main body 2310. One part is used to position the mandrel 2900. There are three adjusting n...

Abstract

The invention discloses a metal mandrel preheater. The preheater comprises a main body, a movable support as well as a heating mechanism and rotating mechanisms which are located on the main body, wherein the movable support is detachably limited in the main body and can bear a mandrel to move on the ground; each rotating mechanism comprises a rotating part, the movable support comprises a first end part and a second end part, the first end part comprises a driven part, two ends of the mandrel can be located at the rotating part and the driven part respectively, the rotating part can drive the mandrel to do the rotation movement in the axial direction of the mandrel, and the heating mechanism can do reciprocating motion between two ends of the mandrel in the axial direction of the mandrel to heat the mandrel. The metal mandrel preheater is high in heating speed, high in efficiency, low in energy consumption, uniform in heating and capable of adapting to rhythmic type continuous production.

Description

technical field [0001] The invention relates to the field of power transmission insulation equipment, in particular to a metal mandrel preheating machine. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] At present, composite insulators are widely used in the power industry. The winding of glass steel pipes in the production process of composite insulators is a crucial link, which has a decisive impact on the mechanical and electrical properties of composite insulators. Before winding the FRP pipe, the metal mandrel for winding must be preheated. The preheating method of the metal mandrel for FRP pipe winding is generally heated by an oven, with an electric heating tube as the heat source, and the heating is realized through hot air circulation. However, the hot air circulation method has disadvantages such as low heat transfer effici...
