Abstract
The invention relates to a furnace door for heating furnaces. Both sides of a door body are provided with weight racks. A weight is disposed in each weight rack. Two chains are connected to trisection positions of the upper edge of the door body. The other end of each chain is connected to the top end of one weight on one side of the door body through a motor and a roller. The motor and the weights coordinate to drive the door body to ascend or descend. A door frame is disposed at the front end of a furnace body. Rails are arranged on the inner side of a door frame. Pulleys are arranged on two sides of the door body and slide in the rails. The tail end of each rail diagonally faces to the inside of the furnace body. The inner wall of the furnace body and the inner side of the door body are both provided with insulation foam. The edges of the insulation foam exceed the edge of the inner wall of the furnace body and the edge of the door body. The furnace door for heating furnaces has the advantages that the motor and the weights drive the door body to ascend and descend, the structure is simple, the furnace door is handy, and energy consumption is decreased.
Description
Technical field
The present invention relates to the corollary equipment of mechanical processing industry, specifically, is the fire door of heating furnace.
Background technology
Workpiece for after forging and welding processing, carry out stress relief annealing processing, then carries out machining, and the quality of heat treatment of workpieces plays to the serviceability of machining accuracy and workpiece the important effect of closing that causes.
Heating furnace is the equipment that steel ingot is heat-treated, and wherein the quality of fire door plays crucial effect to the easy-to-use and heating quality of heating furnace.
Summary of the invention
In order to provide a kind of convenient and practical, the fire door of high insulating effect, the fire door of heating furnace of the present invention, the both sides of fire door are equipped with counter-balanced carriage, in described counter-balanced carriage, be equipped with counterweight, two third-class offices of fire door upper edge are connected with two chains, the other end of two chains is all connected respectively to the counterweight top of fire door both sides by motor and roller, by motor and counterweight acting in conjunction, drive the liter of fire door or fall, the front end of body of heater is provided with doorframe, the inner side of described doorframe is provided with track, the both sides of described fire door are provided with pulley, described pulley slides in described track, the end of described track is arranged to direction in oblique stove, described inboard wall of furnace body and fire door inner side are equipped with heat insulation foam, the edge of heat insulation foam exceeds the edge of described inboard wall of furnace body and the edge of described fire door.
The inner side of both sides doorframe is respectively equipped with two parallel tracks, and the end of two tracks is respectively in two high third-class offices of fire door.
The invention has the beneficial effects as follows: motor adds the landing that counterweight drives fire door, fire door is by deadweight and Electric Machine Control, the pulley of fire door both sides puts the end of fire door two siding tracks under in decline, make fire door press the end in body of heater, the outstanding fire door in edge of heat insulation foam and the edge of body of heater frame, make better tightness, prevent that heat runs off from gap, the present invention is simple in structure, convenient and practical, saves energy consumption.
Accompanying drawing explanation
