Abstract
Gas-heating brazing equipment comprises a gas feed system, a gas heater, a brazing furnace, a flow homogenizer, a heat-preservation layer, a gas exhaust duct, a temperature sensor and a control system. The gas feed system is connected with the gas heater, the brazing furnace and the flow homogenizer in sequence, the heat-preservation layer wraps gas heater and the brazing furnace, the gas exhaust duct is arranged above the brazing furnace, the temperature sensor is installed at the position of a gas exhaust opening of the brazing furnace, and the temperature sensor is connected with the control system. Through the gas-heating brazing equipment, heating efficiency is high, a workpiece is evenly heated, and the structure is simple. Therefore, the gas-heating brazing equipment can be widely applied to small-batch or single-piece production of products needing brazing, of automobiles, industry, civil use and the like.
Description
One, technical field
The present invention relates to a kind of with the heating after high temperature inert gas to the hot brazing equipment of gas that workpiece carries out the Convective Heating soldering, be mainly used in the soldering of small lot or single-piece workpiece.
Two, background technology
Furnace gas protection soldering is the brazing mode of using always, particularly is widely used in the welding in air-conditioning, automobile radiators field.Can be divided into forms such as continuous oven, batch furnace, shaft furnace, batch-type furnace according to furnace binding; their basic principle is under the protection of inert gas in stove carries out the radiation heating soldering to workpiece; heater and furnace wall, the main mode of heating between furnace wall and workpiece is radiation heating.Wherein continuous oven, batch furnace are bulky, and the energy consumption height is mainly used in producing in enormous quantities, is not suitable for the soldering of small lot or single-piece workpiece.Though shaft furnace, batch-type furnace can be used for the soldering of small lot or single-piece workpiece, because the mode of heating of workpiece is mainly radiation heating, so the efficiency of heating surface is lower.And soldering is had relatively high expectations for the control of temperature curve, and the speed that requires temperature to rise is fast as far as possible, and the such equipment that heats in the radiation heating mode of shaft furnace, batch-type furnace need be equipped with powerful heater and just can meet the demands.And radiation heating is had relatively high expectations for the relative size of workpiece and burner hearth, and it is inhomogeneous to be heated, and influences the soldering effect.
Three, summary of the invention
The purpose of this invention is to provide a kind of hot brazing equipment of gas that workpiece is carried out the Convective Heating soldering with the high temperature inert gas after the heating, solve the low efficiency problem that shaft furnace, batch-type furnace etc. adopt radiation heating, be mainly used in the soldering of small lot or single-piece workpiece.
In order to address the above problem, the technical solution adopted in the present invention is: the hot brazing equipment of a kind of gas, comprise gas handling system, gas heater, soldering oven, flow homogenizer, heat-insulation layer, discharge duct, temperature sensor and control system, described gas handling system order is connected with gas heater, soldering oven, flow homogenizer, heat-insulation layer is wrapped in gas heater and soldering oven outside, discharge duct is above an end of soldering oven, temperature sensor is contained in the exhaust ports of soldering oven, and temperature sensor is connected with control system.
Described gas handling system is equipped with pressure-regulating device and flow regulator.
Described gas heater adopts the mode heated inert gas of electrically heated mode or flame heat, and gas heater is with the mode heated inert gas of heat convection, and inert gas is with the mode heated parts of heat convection.
Described flow homogenizer carries out uniform flow to inert gas.
Operation principle and process:
The high-pressure inert gas of normal temperature is through the adjustment of gas handling system, enter gas heater with certain pressure and flow, after the gas heater heating, enter in the soldering oven, behind the flow homogenizer uniform flow, blow to equably on the workpiece in the stove, produce heat convection with workpiece, thereby make workpiece intensification soldering; After the high temperature brazing temperature and time reached setting value, control system was closed the gas heater heating function, and inert gas enters in the stove with normal temperature workpiece is cooled off; Gas after the heat exchange is drained by discharge duct; Detect the exhaust temperature of inert gas with temperature sensor, and feed back to control system, control system to heating-up temperature, the heat time heating time of workpiece of inert gas, detect cool time and control.
The beneficial effect that the present invention reaches is:
1, gas heater is Convective Heating to the heating of inert gas and high temperature inert gas to the heating of workpiece, and the efficiency of heating surface is than radiation heating height.
2, inert gas not only plays the heating and cooling workpiece in brazing process, plays atmosphere protection simultaneously.
3, the gas through flow homogenizer carries out uniform heating and cooling to workpiece, and the soldering effect is better.
4, device structure is simple, can be widely used in automobile, industry, small lot or the single-piece production that needs the product of gas protecting soldering such as civilian.
Four, description of drawings
Fig. 1 is the structural representation of the hot brazing equipment of gas of the present invention.
Five, the specific embodiment
Below technology of the present invention constituted be described in further detail.
Contrast Fig. 1, the hot brazing equipment of gas of the present invention, comprise gas handling system 1, gas heater 2, soldering oven 3, flow homogenizer 4, heat-insulation layer 5, discharge duct 6, temperature sensor 7 and control system 8, described gas handling system 1 order is connected with gas heater 2, soldering oven 3, flow homogenizer 4, heat-insulation layer 5 is wrapped in gas heater 2 and soldering oven 3 outsides, prevents that heat runs off.Discharge duct 6 is located at the top of soldering oven 3, and temperature sensor 7 is contained in the exhaust ports of soldering oven 3, for detection of the exhaust temperature of inert gas, and feeds back to control system 8.Temperature sensor 7 is connected with control system 8.Control system 8 receives the temperature signal of temperature sensors 7, closes gas heater 2 heating power supplies after reaching the brazing temperature required value, stops the inert gas heating, and inert gas enters in the soldering oven 3 with normal temperature workpiece is cooled off.After the exhaust temperature of inert gas reached the cooling required value, control system 8 was closed gas handling system 1, stops air feed.
Described gas handling system 1 is equipped with pressure-regulating device and flow regulator.Can regulate and control pressure and the flow of inert gas.
Described gas heater 2 adopts the mode heated inert gas of electrically heated mode or flame heat, and gas heater 2 is with the mode heated inert gas of heat convection, and inert gas is with the mode heated parts of heat convection.
