Abstract

The invention relates to a hold-down device of a furnace door of a heating furnace, which can be arranged at outer sides at two sides of the furnace door and inner sides of a doorframe at two sides of the furnace door, pulleys are provided at the end part of a projection, the tracks are provide at the inner side of the doorframes at two sides, an oblique orbit oblique to the furnace is provided on the end portion of the track, and the pulleys are respectively connected to the track in a sliding mode. Two tracks are respectively provided at the inner side of doorframes at two sides, two tracks are vertically arranged in a parallel mode, wherein the oblique orbit connected to one track is positioned at 1/3 height of the furnace door, the oblique orbit connected to the other track is positioned at 2/3 height of the furnace door. The hold-down device has the beneficial effect that the furnace door deadweight of a motor is used, when the furnace door descends to close, the pulleys automatically sliding into the oblique orbit from the track to cling to a furnace body, so that the good sealing effect can be reached.

Description

The hold-down gear of Compaction of Heating Furnace Door

Technical field

The present invention relates to the support equipment of mechanical processing industry, specifically, is the hold-down gear of Compaction of Heating Furnace Door.

Background technology

Workpiece for after forging and welding processing, carry out stress relief annealing processing, then carries out mechanical workout, and the quality of heat treatment of workpieces plays to the use properties of machining accuracy and workpiece the important effect of closing that causes.

Process furnace is the equipment that steel ingot is heat-treated, and wherein the quality of fire door plays crucial effect to the sealing of process furnace, heating quality.

Summary of the invention

Heating quality in order to ensure process furnace is high, the good sealing effect of fire door, the present invention has developed the hold-down gear of Compaction of Heating Furnace Door, be arranged at the outside of fire door both sides and the inner side of fire door both sides doorframe, outside in described fire door both sides is equipped with projection, and the end of projection is provided with pulley, in the inner side of doorframe described in both sides, is equipped with track, the end of described track is provided with the oblique orbit in oblique stove, and described pulley is dynamically connected with described track sliding respectively.

The inner side of both sides doorframe is respectively equipped with two tracks, and two parallel tracks vertically arrange, and the oblique orbit that one of them track connects is at high approximately 1/3rd places of fire door, two places that the oblique orbit that another track connects divides at fire door Gao Yuesan.

The invention has the beneficial effects as follows: utilize deadweight and the motor of fire door, when fire door decline is closed, pulley slips into oblique orbit from track automatically, thereby is close to body of heater, reaches good sealing effectiveness.

Accompanying drawing explanation

Fig. 1 is structure iron of the present invention.

Embodiment

As shown in Figure 1, the hold-down gear of Compaction of Heating Furnace Door of the present invention, be arranged at the outside of fire door 1 both sides and the inner side of fire door 1 both sides doorframe 2, outside in described fire door 1 both sides is equipped with projection, the end of projection is provided with pulley 3, in the inner side of doorframe described in both sides 2, be equipped with track 4, the end of described track 4 is provided with the oblique orbit 5 in oblique stove, and described pulley 3 is slidably connected with described track 4 respectively.

The inner side of both sides doorframe 2 is respectively equipped with 4, the two track 4 parallel vertical settings of two tracks, and the oblique orbit that one of them track connects is at high approximately 1/3rd places of fire door 1, two places that the oblique orbit that another track connects divides at fire door 1 Gao Yuesan.

The present invention is by the deadweight of fire door, and 1 decline of electric machine control fire door, and pulley 3 slides in track 4, naturally slips in oblique orbit 5, makes fire door 1 be close to body of heater, reaches good sealing effectiveness.
