Traditional car-type mold heated table car drives at the chassis head, and floor space is big, and is heavy, not attractive in appearance in appearance.
Traditional car-type mold heated furnace body is a burner hearth only, the waste material cost with make man-hour, cost performance reduces greatly.
Summary of the invention
The deficiency that exists to prior art, but the object of the invention provides a kind of energy-conservation, consumption reduction economical with materials cost and makes the multicell die preheating furnace in man-hour.
To achieve these goals, the present invention realizes through following technical scheme:
The present invention includes at least two separate burner hearths of shared same body of heater, with the corresponding fire door of each burner hearth be used to control the fire door push-pull mechanism of corresponding fire door push-and-pull; Fire door is provided with and is used to place the workpiece bearing frame of treating the preheating workpiece; The both sides and the top side of each burner hearth are respectively equipped with deflector; Deflector is divided into operating room and air channel with burner hearth; Be provided with heater block in the air channel; Leave air outlet between the deflector lower end of both sides and the burner hearth, have the inlet scoop on the deflector of top side, also be provided with in the air channel and the corresponding circulating fan in inlet scoop.
Above-mentioned fire door push-pull mechanism comprises the dolly that is connected with fire door, and dolly advances and retreat through the driving device controls dolly.
Above-mentioned drive unit is installed in the bottom of body of heater.
What above-mentioned drive unit adopted is electric pushrod, cylinder, oil cylinder or reductor.
Be provided with potted line between above-mentioned each fire door and the body of heater.
The present invention has significantly reduced the contact area of former trolley body in body of heater, has practiced thrift resource and cost, and the complete machine floor space is little, limpid in appearance, novel, simplicity generosity, and effectively practiced thrift material cost and made man-hour, improved the cost performance of equipment.
Description of drawings
Fig. 1 is the front view of present embodiment;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Each label among the figure: body of heater 1, treat preheating workpiece 2, fire door 3, workpiece bearing frame 4, deflector 5, air channel 6, operating room 7, heater block 8, air outlet 9, inlet scoop 10, circulating fan 11, dolly 12, drive unit 13, potted line 14.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment comprise shared same body of heater 1 two separate burner hearths, be installed in the fire door 3 on each burner hearth and be used to control the fire door push-pull mechanism of corresponding fire door 3 switches.
Wherein, body of heater 1 is made up of furnace roof, furnace bottom and sidewall.Because of two shared bodies of heater 1 of burner hearth, effectively practiced thrift material cost and made man-hour, improved the cost performance of equipment.
Be provided with workpiece bearing frame 4 in the inboard of each fire door 3, treat that preheating workpiece 2 is placed on the workpiece bearing frame 4.
The and arranged on left and right sides of each burner hearth and top side are respectively equipped with 5, three deflectors 5 of deflector burner hearth are divided into two parts, the air channel 6 of a part for forming between the and arranged on left and right sides of deflector 5 and burner hearth and the top side; A part is operating room 7 in addition; Heater block 8 is installed in the air channel 6, leaves air outlet 9 between deflector 5 lower ends of both sides and the furnace bottom, have inlet scoop 10 on the deflector 5 of top side; Also be provided with in the air channel 6 and inlet scoop 10 corresponding circulating fans 11, constitute hot air circulation.
In the present embodiment, it is the electric heating tube of stainless steel tube that heater block 8 adopts outer tube, is made into integral hoisting formula structure, is installed in the air channel 6 of and arranged on left and right sides of the present invention.
The present invention has replaced the charging method of traditional car type furnace, and sealing is unreliable causes warm phenomenon with Louing because of dolly 12 and body of heater 1 to have solved traditional chassis 12 stoves, and replaces traditional chassis 12 stove dollies 12 bodies caloric receptivity greatly.The present invention has played energy-saving and cost-reducing effect, has reduced equipment operating cost.
In the present embodiment, the fire door push-pull mechanism comprises the dolly 12 that is connected with fire door 3 outsides, and wherein, dolly 12 is controlled advancing of dollies 12 through drive unit 13 and retreated, and promptly drive unit 13 is used to push away, draws dolly 12.
