Abstract
The utility model discloses a piston salt core preheating furnace which solves the problem that the existing salt core preheating furnaces can not ensure salt core preheating quality. The piston salt core preheating furnace preheats a salt core before the salt core is moulded in piston roughcast and has the advantages of energy-saving, high efficiency, convenient use, etc. The piston salt core preheating furnace has the structure that a furnace body is inclued; the furnace body is arranged on a base through a bracket; the furnace body is provided with a furnace door; the inner wall of the furnace body is provided with fire resisting materials; a heating device is arranged in the furnace body; a chassis of the furnace body is connected with a rotating device; a multiple-layer bracket connected with a rotating disc is arranged in the furnace body; the salt core is placed on the bracket in vertical direction.
Description
Technical field
The utility model patent relates to a kind of preheating furnace, relates in particular to a kind of piston salt core preheating furnace.
Background technology
The salt core forms the piston inner cooling path by being cast into piston blank, the employing of inner cooling path can effectively reduce the head temperature of piston, to adapt to the raising of engine power density, this technology is adopted widely, produced huge economic benefit and social benefit, the key of this technology is being cast into of salt core.And the preheating that is cast into secondary piston salt core is related to the inner cooling path quality, crosses the core that desalts and is cast into the preceding preheating method employing of piston blank cabinet-type electric furnace, and its structure is the refractory material burner hearth, the outside resistance wire that twines, the refractory material thermal conductivity is relatively poor, and the electric furnace energy consumption is big, non-uniform temperature in the burner hearth; Former electric stove hearth is a rectangle, after the salt core is put into, can't realize first in first out aborning, in use, the salt core of putting at last often, the position is near the fire door position, and the use at first that preheating is the poorest can't guarantee the pre-thermal mass of salt core.
Summary of the invention
The purpose of this utility model can not guarantee problems such as the pre-thermal mass of salt core in order to solve present salt core preheating furnace exactly, provide a kind of before the salt core is cast into piston blank preheating salt core, the piston salt core preheating furnace with advantage such as energy-conservation, efficient, easy to use.
For achieving the above object, the utility model adopts following technical scheme:
A kind of piston salt core preheating furnace, it comprises body of heater, and body of heater is installed on the base by support, and body of heater is provided with fire door, and inboard wall of furnace body is provided with refractory material, is provided with heater in the body of heater, and described furnace body chassis is connected with tumbler; Be provided with the multilayer support that is connected with rotating disk in body of heater, the salt core is placed by vertical direction on support.
Described heater is direct thermal-radiating heater, and each heater has corresponding thermocouple, and heater is arranged on the lateral surface or the outer end face of body of heater, and corresponding thermocouple then is arranged on furnace body inside portion or inner top.
Described tumbler comprises rotating shaft, and rotating shaft then is connected with motor.
Described tumbler comprises rotating shaft, and rotating shaft is provided with handwheel.
Seal by maze trough between described furnace body chassis and body of heater.
The utility model salt core preheating furnace adopts the end mode of changeing, and uses handwheel to rotate, and drives the whole chassis rotation, and the salt core moves with the chassis.On direction of rotation, also can be arranged to unidirectional rotation.The rotating manner on chassis also can be realized by driven by motor.By adopting rotation mode, can reach following purpose:
(1) the salt core picks and places easily.When putting into the salt core, after a station salt core is piled, rotate to next station and continue to put.Get the salt core roughly the same.Be convenient to produce in enormous quantities.
(2) the pre-thermal mass of salt core is good, and the salt core is rotatable with the chassis, can avoid the salt core to rest on low-temperature space all the time, as the fire door district.Can improve the pre-thermal mass of salt core so greatly.
The salt core can adopt multilayer to place in vertical direction.The utility model salt core is in vertical direction, and the salt core is placed the number of plies, can be by 1,2,3 ..., multilayer is arranged, and what increased stove effectively utilizes area, adopts when being convenient to produce in enormous quantities.
The mode of heating of salt core preheating, being conducted heat by the furnace wall by the past changes direct radiation into.Heater housing is a stainless steel.Heater can also can be arranged in end face in the side.Thermocouple can be arranged in middle or lateral location thereupon.
The beneficial effects of the utility model are: simple in structure, easy to use, salt core pre-heat effect is good.
