Abstract
A push rod type double-grate low-temperature tempering furnace comprises a feeding device, a furnace body and a discharging device, wherein an upper heating chamber and a lower heating chamber are arranged in the furnace body, a double-grate guide rail is arranged in the lower heating chamber, a charging tray is arranged on the guide rail plane, and a large-impeller centrifugal fan and a group of electric heating bodies are arranged at one end of the upper heating chamber. A front furnace door and a rear furnace door are respectively arranged on the front end lateral surface and the rear end lateral surface of the furnace body. The feeding device is composed of a tempering furnace push rod arranged right ahead the furnace body and a feeding flexible push rod arranged outside the front furnace door. The discharging device is composed of a discharging pull rod arranged outside the rear furnace door and a discharging flexible push rod arranged on the other side of the rear furnace door. The layout of double-grate material positions is adopted in the furnace so that the integral length of the tempering furnace can be reduced by a half, floor space of the tempering furnace is greatly reduced, energy consumption is reduced, and loss of heat in the furnace caused by furnace door opening can be greatly reduced due to the doors arranged on the lateral surface of the tempering furnace.
Description
Technical field
The utility model relates to a kind of thermal treatment low-temperaturetempering stove, specifically, relates to the double low-temperaturetempering stove of a kind of push-down.
Background technology
Low-temperaturetempering is claimed " stress relief tempering " again.Tempering range is 150-250 degree centigrade, is organized as tempered martensite after the tempering.Steel has high firmness and high-wearing feature, but internal stress and fragility reduce.Low-temperaturetempering is mainly used in the tool mould and the rolling bearing of high carbon steel and high-carbon alloy steel manufacturing, and through carburizing and hard-faced part, the hardness after the tempering is generally 58-64HRC.
Along with the weight-carrying capacity of truck is increasing, the modulus of truck transmitting gear is also increasing, and the tempering time after the automobile gear carburizing requires more and more longer.In the prior art, by the requirement lengthening tempering stove of tempering time, and because the restriction of the thrust of tempering stove feed mechanism, impossible unrestricted lengthening tempering stove is so in some Special Circumstances, use two low-temperaturetempering stoves.No matter be the lengthening tempering stove, also be to use two tempering stoves, have all that occupation area of equipment is big, the workshop utilization ratio is low, the equipment cost cost significantly improves, equipment energy consumption improves or the like problem.
The utility model content
To above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and reduces the tempering stove floor space significantly, reduces the double low-temperaturetempering stove of push-down of energy expenditure.
The technical scheme that the utility model is taked is:
The double low-temperaturetempering stove of a kind of push-down; Comprise: feeding unit, body of heater, drawing mechanism; Be provided with heating chamber and following heating chamber in the said body of heater; Be provided with double guide rail in the heating chamber under said, charging tray places on the said guide level, and a said end of going up heating chamber is equipped with big impeller centrifugal fan and one group of electric heating element.
Fire door and back fire door before said body of heater front end side and side, rear end are respectively arranged with.
Said feeding unit is made up of tempering stove push rod that is arranged on the body of heater right on and the soft push rod of charging that is arranged on the forehearth outer side of door; Said drawing mechanism is made up of the soft push rod of discharging that discharging pull bar that is arranged on the fire door outside, back and body of heater are provided with the opposite side of back fire door.
The beneficial effect of the relative prior art of the utility model:
The double low-temperaturetempering stove of the utility model push-down; Owing in stove, adopt the layout of double material level; Make the entire length of tempering stove shorten half, reduce the tempering stove floor space significantly, reduce energy expenditure; Opening the door in the side of tempering stove, can reduce significantly because the loss of furnace heat when door opened.

Embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment:
Accompanying drawing 1-3 can know; The double low-temperaturetempering stove of a kind of push-down; Comprise: feeding unit, body of heater 1, drawing mechanism, be provided with heating chamber 2 and following heating chamber 3 in the said body of heater 1, be provided with double guide rail 16 in the said following heating chamber 3; Charging tray 7 places on said guide rail 16 planes, and a said end of going up heating chamber 2 is equipped with big impeller centrifugal fan 5 and one group of electric heating element 4; Fire door 10 and back fire door 11 before said body of heater 1 front end side and side, rear end are respectively arranged with; Said feeding unit is made up of tempering stove push rod that is arranged on body of heater 1 right on 9 and the soft push rod 13 of charging that is arranged on the forehearth outer side of door; Said drawing mechanism is made up of the soft push rod 8 of discharging that discharging pull bar 12 that is arranged on fire door 11 outsides, back and body of heater 1 are provided with the opposite side of back fire door 11.
The double low-temperaturetempering stove of the utility model push-down tempering stove is divided into heating chamber and following heating chamber two Room, in the following heating chamber double guide rail is housed, and charging tray places on the guide level.One end of last heating chamber is equipped with a big impeller centrifugal fan and one group of electric heating element; Blower fan will descend the gas of heating chamber to drink up during work; Blow out by the blower fan outlet again air is blowed to well heater; Air is heated through electric heating element, and heated air returns following heating chamber again through flow deflector is heated the workpiece in the heating chamber, so that the air in the stove forms circulation loop.
The double low-temperaturetempering stove of the utility model push-down; Owing in stove, adopt the layout of double material level; Make the entire length of tempering stove shorten half, reduce the tempering stove floor space significantly, reduce energy expenditure; Opening the door in the side of tempering stove, can reduce significantly because the loss of furnace heat when door opened.
