Description
Technical field
The present invention relates to technical field of heat treatment, and in particular to before a kind of plastic tubing assembly of car engine assembly
The pre-add hot stove of preheating.
Background technique
The assembly of the plastic tubing of car engine assembly generally using interference fit, needs before assembly to plastic tubing
Heating is carried out to be allowed to slightly expand.Preheating stove heating is high-efficient, and easy temperature control system is that plastic tubing preheating first choice is set
It is standby.The plastic tubing specifications and models of car engine assembly are more, traditional only one charging tray of pre-add hot stove, all workpiece
It is both placed on a charging tray, needs to reclassify the specification and type of workpiece after preheating, larger workload.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of pre-add hot stove, it is to be heated by the way that several charging trays packing are arranged
Oil pipe part saves the classification process of workpiece after heating, improves efficiency.
For this purpose, the technical solution adopted by the present invention is that：The bottom of a kind of pre-add hot stove, including furnace shell, furnace shell is equipped with grate,

Element, roof of the furnace are equipped with air outlet, and air outlet is connected to air duct；Sliding is equipped with several charging trays, the charging tray edge in burner hearth
Burner hearth length direction extends.
Heated work pieces to be added are divided in different charging trays by different size model, and electrical heating elements heating power is recycling
Under the action of blower, hot wind presses to burner hearth two sides air duct backward along the shunting of top deflector, enters burner hearth through partition bottom, adds
It is sucked back again through air outlet (i.e. fan induced draught mouth) by circulating fan after heated work pieces, then the outlet through circulating fan is again along two crosswind
Road pushes, and so constantly recycles in burner hearth, so that the workpiece in charging tray be made to obtain good temperature uniformity, fills product
Divide thermally equivalent, improves product processing quality.
Further, the charging tray be by bottom plate, left side plate, front and back end board group at drawer, bottom plate, left side plate,
Several ventilation holes are offered on end plate.The setting of drawer facilitates the pick-and-place and classification of heated work pieces to be added, the setting of ventilation hole
In order to improve the heated uniformity of heating efficiency and workpiece.
Further, steel wire is all covered positioned at the upper surface of the charging tray of burner hearth top layer.The charging tray of burner hearth top layer
Close to the suction inlet of circulating fan, plastic tubing is lighter, easily brings blower when wind-force is larger into the wind, and setting steel wire intercepts.
Further, two one group of the charging tray, every group of charging tray is correspondingly provided with a fire door.The specification of heated work pieces to be added is not
Together, heating time difference, is arranged multiple fire doors, can make to heat in other charging trays when opening fire door and picking and placing workpiece
Workpiece is unaffected, prevents from making because door opened the workpiece temperature in the charging tray of fire door to lower, influences its temperature rise uniformity.
Further, furnace lining is equipped in the furnace shell, furnace lining is filled using high-quality alumina silicate refractory fiber cotton, and inner wall uses
Steel plate encapsulation.The heat insulation effect of aluminosilicate refractory fiber cotton is good.
Further, the top of the burner hearth is equipped with dehumidification tube, and one end of dehumidification tube is connected to burner hearth, and the other end passes through wind
Road is communicated with the atmosphere.The import of the further preferred dehumidification tube is equipped with steel wire, and outlet is equipped with automatic valve.Dehumidification tube is for arranging
Damp-heat air in flake hearth-tapping improves heating efficiency.The bore exported by automatic valve regulation dehumidifying pipelines, when heating, open, and protect
It is closed when warm or half-open, adjusts temperature and humidity in burner hearth.Moisture exhausting port installs stainless (steel) wire additional, prevents workpiece inspiration moisture exhausting port.
Further, the electrical heating elements are U-shaped electric heating finned tube, by the wind for being inserted into burner hearth two sides at the top of furnace shell
In road, the electric heating finned tube outside furnace shell is equipped with protective cover, and protective cover is used for the binding post including electric heating finned tube.
The U-shaped electric heating tube of I font setting, structure is simple, and heating efficiency is high.
Further, the heating furnace is equipped with a temperature measurer, temperature measurer at least provided with more than two warm areas, each warm area
The temperature inside burner hearth for measuring each warm area.By observing the temperature of temperature measurer, controls the heating of burner hearth and kept the temperature
Journey.
Further, the heating furnace further includes PLC control system, PLC control system respectively with electrical heating elements, thermometric
Instrument, automatic valve and circulating fan connection.The automatic control for entirely heating process, temperature measurer may be implemented by PLC control system
The temperature simulation amount parameter of measurement is sent to the controller of control system at any time to, controller controls the automatic of dehumidifying pipelines outlet
The temperature and time of the open degree of valve and the size of electrical heating elements thermal power, control heating and heat preservation.Control system also controls
The start and stop and frequency of circulating fan, control the cycle-index of blower.
Beneficial effects of the present invention：Compared with prior art, pre-add hot stove of the invention can realize that different size is to be heated
The packing of workpiece saves the classification process of element after heating, high-efficient.The pre-add hot stove thermal uniformity of invention is high, heater
The quality of part is high.
