Because the quality of workpiece crudy is mainly determined by the technological parameter in the heating soldering district, thereby when operation, at first determine technological parameter in the heating soldering district according to the processing request of different workpieces, determine the parameter that other are regional by the technological parameter in the heating soldering district again, and adjust the time that workpiece rests on respective regions by the control driving chain.In actual the use, the relative higher preheating purifying area connection of the feed end in heating soldering district with temperature, and the relatively low cooling zone of the discharge end in heating soldering district and temperature is connected, thereby be easy to generate bigger temperature difference at the two ends in heating soldering district; And the improper temperature contrast that also can cause the workpiece positive and negative of mode of heating.The soldering processing requirements is finished under the uniform atmosphere of temperature, and this has just proposed higher requirement to the heater in the heating soldering district.The simple heater of tradition continous way gas protecting soldering furnace can not meet the demands.
Three, summary of the invention
The heater that the purpose of this invention is to provide heating soldering district in a kind of intermittent type gas protecting soldering furnace; this heater can accurately heat the heating soldering district; make whole heating soldering district temperature even, satisfy the technological requirement of intermittent type gas protecting soldering furnace.
The objective of the invention is to be achieved through the following technical solutions:
The heater in heating soldering district in a kind of intermittent type gas protecting soldering furnace, it is characterized in that: it comprises tubular electric heating and heating cabinet, and described tubular electric heating is arranged on the top in heating soldering district and is positioned at the air outlet below of thermal circulation fan, location of workpiece top; The bottom that heating cabinet is arranged on the heating soldering district is positioned at the outside of location of workpiece below burner hearth bottom; The tubular electric heating that can adjust heating-up temperature is connected with temperature control instrument with heating cabinet.
Among the present invention, for improving the thermal efficiency, the outside of burner hearth bottom is provided with the electrical heating case below driving-belt and workpiece, can utilize tubular electric heating and the electrical heating case thermal effect that adds to the direct radiation generation of workpiece so better,
Among the present invention, be to improve the efficiency of heating surface, tubular electric heating and heating cabinet be one group several.The packaged type heating cabinet of described one group of heating cabinet for ease of changing.The quantity of heating cabinet and heating power can be determined according to technological requirement.
For ease of tubular electric heating is carried out the temperature adjustment.Tubular electric heating below be provided with temperature sensor, temperature controller carries out temperature control according to the data of temperature sensor to tubular electric heating.Temperature adjustment to tubular electric heating can be many, also can be predefined some specific tubular electric heatings.
Owing to need enough protective gas atmosphere in the heating soldering district, leak for preventing protective gas, in the two-port of every group of tubular electric heating seal washer and the locking nut that prevents that protective gas from leaking is housed all.
For guaranteeing to have even temperature field and protective gas atmosphere in the heating soldering district, be provided with thermal circulation fan in a group in the heating soldering district, the thermal circulation fan place is provided with temperature sensor in each.During operation, can control tubular electric heating, realize the purpose of homogeneous temperature field according to the data that temperature sensor records.Usually whole heating soldering can be distinguished into two temperature-controlled areas, be soldering one district and soldering two districts, in each district, an interior thermal circulation fan and one or two temperature sensor are set respectively, and can adjust tubular electric heating, the electrical heating case of each temperature-controlled area separately, be used for the uniform requirement of satisfied temperature.
The present invention controls the temperature in the heating soldering district by the thermometer, temperature sensor and the tubular electric heating that are provided with; can accurately heat the heating soldering district; make whole heating soldering district temperature even, satisfy the technological requirement of intermittent type gas protecting soldering furnace.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic cross-section in heating soldering district among the present invention.
Five, the specific embodiment
The heater in heating soldering district in a kind of intermittent type gas protecting soldering furnace, comprise one group of tubular electric heating 1 and one group of heating cabinet 2, tubular electric heating 1 is arranged on the top in heating soldering district and is positioned at the air outlet below of thermal circulation fan 3, top, workpiece 5 positions; The bottom that heating cabinet 2 is arranged on the heating soldering district is positioned at the outside of below, workpiece 5 positions burner hearth bottom.The tubular electric heating 1 that can adjust heating-up temperature is connected with temperature control instrument with electrical heating case 2.
Protective gas among the present invention can be an inert gas, also can be nitrogen, and present embodiment adopts nitrogen.
For ease of changing and adjust heating process, tubular electric heating 1 and heating cabinet 2 be one group several.Heating cabinet 2 is the packaged type heating cabinet.The quantity of heating cabinet 2 and heating power can be determined according to technological requirement.
For ease of tubular electric heating 1 is carried out the temperature adjustment.Tubular electric heating 1 below be provided with temperature sensor 4, temperature controller carries out temperature control according to the data of temperature sensor 4 to tubular electric heating 1.The tubular electric heating 1 that can carry out the temperature adjustment is predefined some specific tubular electric heatings.
For preventing that protective gas from leaking, seal washer and the locking nut that prevents that protective gas from leaking all is housed in the two-port of every group of tubular electric heating 1.
