Description

A kind of horizontal type does not have not push-down continuous braze welding stove of horse
Technical field
The utility model relates to brazing equipment, and particularly a kind of horizontal type does not have not push-down continuous braze welding stove of horse.
Background technology
The continuous oven brazing in controlled atmosphere is that the parts with complicated shape disintegrate into a plurality of simple shape parts that carry out processing and manufacturing easily; The continous way soldering furnace brazing of again part and the corresponding scolder assembly of these simple shapes being put into protective atmosphere; Make it to become one and have enough bonding strengths; Sealing, the complicated shape parts that precision is high.The basic characteristics of this technology are non-oxidation, fluxless, high-quality, high efficiency, low cost, and economizing can material-saving; Be fit to the intensification production of imperial scale; Particularly at high efficiency, high-quality, low-cost aspect is that traditional any soldering, high frequency brazing etc. are incomparable
To in enormous quantities, high-quality, low cost, the bright soldering of ordinary steel, low-alloy steel, copper, cast iron materials goods, the international horizontal that adopts usually has not net belt type continuous braze welding stove of horse.
Horizontal have horse not the architectural feature of net belt type continuous braze welding stove be: heat-resisting steel furnace muffle tube is housed in the body of heater, furnace muffle tube and displacement band boiler tube, water salband boiler tube forms a straight line through channel; Soldering feeds in this through channel with protective gas; Be loaded with the heat-resisting steel guipure of welded piece,, export by the speed that sets at the uniform velocity through replacing band, furnace muffle tube (by the body of heater heat), salband completion brazing process from entering the mouth to along passage bottom; Be that anti-outside air immerses, go into, the exit establishes fire envelope and door curtain.
Above-mentioned horizontal type have horse not net belt type continuous braze welding stove can realize light, high-quality, high efficiency soldering to material products such as ordinary steel, low-alloy steel, copper, cast irons; Though than employing bridge type net belt type continuous braze welding stove remarkable economic efficiency is arranged, but still has suitable weak point.Wherein:
1, the heat resisting steel horse not cost is high, the life-span is low, and is fragile.
2, the heat resisting steel horse not has the characteristics of expanding with heat and contract with cold, the walking mechanism of must guaranteed horse in the soldering oven global design is made not freely stretching, and cause the soldering oven structure complicacy that becomes.
3, for guaranteeing the life-span of furnace muffle tube, unsuitable frequent intensification the, cooling.
4, for guaranteeing horse life-span not, heating up must be slowly, and the heating-up time is long.
5, for guaranteeing that horse not and belt life, rises to before the heat resisting steel oxidizing temperature, must in the boiler tube passage, feed protection gas, increase protection gas consumption and the loss of stove internal power thus.
6, for the protection horse not and belt life, when blowing out lower the temperature, must continue to feed to protect gas, under the heat resisting steel oxidizing temperature, just can stop, this has also significantly increased the consumption and the energy consumption of protective gas.
7, in the welding process owing to be that the guipure load-carrying unit uninterruptedly moves, soldering oven gateway fire door must be in normally open.So just caused protective gas in the stove be easy to scatter and disappear and outside air is very easily invaded, cause the destruction of furnace atmosphere purity and influence brazing quality.Be protection furnace gas purity,, must strengthen protective gas and inject the flow in the stove, the consumption that has increased energy and resource thus except that fire door flame enrichment envelope and door curtain.
8, the heat resisting steel guipure should not bear big load.
9, heat resisting steel guipure cost is high, and is fragile.
10, be to put welded piece on the guipure that is in operation during soldering, put to be difficult to reach for complex-shaped workpiece and the most effectively utilize the space, obtain most economical effect, influence production efficiency.
Summary of the invention
