Problems solved by technology
[0004] The purpose of the present invention is to provide a vacuum furnace to solve the problem that the traditional vacuum furnace is generally straight and smooth. When calcined at high temperature, the furnace will break because of its insufficient hardness, which not only brings trouble to the production process , but also caused great danger to users

Embodiment Construction
[0013] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0014] Such as figure 1 As shown, this embodiment provides a vacuum furnace, including a furnace body 1, a pressure sealing head 3 arranged at the bottom of the furnace body 1, a flange part 4 surrounding the outside of the furnace body 1, and a A plurality of reinforcing ribs 2 between the furnace body 1 and the flange part 4, the furnace body 1 is welded after being rounded and corrugated, and the reinforcing ribs 2 are grooved and marked with "C" "The font surrounds the front and back of the furnace body 1. The number of reinforcing ribs 2 is 4~6, and each of the reinforcing ribs 2 is in the shape of an arc groove and arranged horizontally around the outer periph...

A vacuum internal furnace comprises an internal furnace body, a press seal head, a flange material and reinforcing ribs, wherein the press seal head is arranged at the bottom of the internal furnace body, the flange material is arranged on the lower portion of the internal furnace body, and the reinforcing ribs are arranged between the internal furnace body and the flange material. The internal furnace body is formed by welding stainless steel plates in a rolling pressure wave mode, then the strength of the internal furnace body can be improved while the thickness of the wall of the internal furnace body does not need to be increased, and the internal furnace body can slightly deform when being heated due to the effect of expansion and contraction. Due to the fact that the internal furnace body is made into a wave shape and the reinforcing ribs are in the shapes of grooves and surround the internal furnace body in a C-shaped mode, the internal furnace body can not remarkably deform, and heated objects inside the vacuum internal furnace can not be greatly affected.
Description
technical field [0001] The invention relates to the field of manufacturing equipment in the mechanical processing industry, in particular to a heating element of a vacuum furnace. Background technique [0002] Industrial furnace occupies an extremely important position in the heat treatment process of machinery manufacturing industry. It is an essential key equipment to ensure product quality, improve machine working efficiency and prolong machine service life. With the rapid development of machinery manufacturing and equipment manufacturing, the demand for industrial furnaces is increasing year by year, so the improvement of industrial furnaces has become a very important and particularly prominent issue. The furnace of the traditional vacuum furnace is generally straight and smooth. When it is calcined at high temperature, the furnace will break because of its insufficient hardness. This not only brings trouble to the production process, but also causes great harm to the u...
