Push shovel heating forming device

Abstract

The invention discloses a push shovel heating forming device, and belongs to the technical field of forming equipment. The push shovel heating forming device is a heating forming integrated production line and comprises a feeding device, wherein the feeding device is connected with a diathermic induction type heating device; the diathermic induction type heating device is connected with a conveying device; and the conveying device is connected with a press machine forming mold, is controlled through a control cabinet and provides medium-frequency electric energy through a transformer. The push shovel heating forming device has the advantages that the diathermic induction heating efficiency is high, workpieces move in an induction coil of a heating furnace in a reciprocating manner and are heated uniformly, a machining process is controlled through temperature, displacement and a motor, the device is reliable, the heating temperature is easy to control, thermal stress and pressure stress are uniform and consistent, the shape preserving precision of the workpieces is high after the workpieces are cooled down, the heating efficiency mode of the heating mold is higher than that of the original box type electric resistance wire heating mode by 30%, the efficacy of the heating mode is higher than that of the original box type electric resistance wire heating mode by 25%, workpiece conveyance is controlled automatically through carrier rollers and a propelling chain, and the push shovel heating forming device is flexible and convenient to operate and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of molding equipment, in particular to a pushing blade heating molding device. Background technique [0002] In the existing bulldozer molding technology for graders, a box-type resistance heating furnace is often used to heat the metal plate of the bulldozer in a closed state, and the material blank is sent into the electric furnace through the feeding device for direct heating, and the electric furnace is energized by the resistance wire to heat up through radiation and Convection is used to heat the metal plate. Due to the large size of the parts, the electric heating furnace is affected by the temperature field in the furnace, and the heating uniformity of the parts is affected. At the same time, the heat is lost in the furnace, which consumes a lot of energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a push shovel heating forming devic...
