Abstract
The utility model provides a cross girder heat equilibrium automatical control device of a plate vulcanizer, which comprises a controller, a heat medium input device, a heat circulation channel, etc. The utility model is characterized in that the upper part of the cross girder away from the heat plate is provided with the heat medium channel; when the vulcanizer works, the heat medium of the microprocessor control can enter the heat circulation channel by the heating resistor in the temperature detection hole inputting temperature difference electric signals to the microprocessor; the temperature of the two sides of the cross girder can be self adjusted; so the utility model can maintain the heat equilibrium of the cross girder and can accomplish the automatical control of preventing the cross girder generating heat deformation.
Description
The utility model relates to a kind of vulcanizing press crossbeam heat balance device.
Existing vulcanizing press is in sulfidation, hot plate temperature is generally more than 150 ℃, because the heat insulation medium between hot plate and the crossbeam can not be heat insulation fully, cause the close surface temperature of crossbeam and hot plate to reach about 100 ℃, and crossbeam and hot plate away from surface temperature have only about 50 ℃, cause crossbeam to produce thermal deformation, and influence the quality of whole vulcanizer vulcanizate.
Task of the present utility model provides a kind of crossbeam heat balance device, and it can adjust the two-part temperature of crossbeam, keeps crossbeam thermal balance, prevents that thermal deformation from appearring in crossbeam, thereby guarantees the quality of vulcanizer vulcanizate.
Task of the present utility model is finished by following approach: away from the top of hot plate (2) hot media channel (8) is set at crossbeam (1), and be provided with controller (4), thermal medium input unit (5), thermal medium output device (6) and temperature survey part (3), when crossbeam (1) is lower than temperature of lower near hot plate (2) and reaches certain numerical value away from the upper temp of hot plate (2), in hot media channel (8), feed thermal medium and improve the temperature of crossbeam (1) away from the top of hot plate (2), the whole temperature of crossbeam (1) is reached unanimity, prevent that crossbeam (1) from producing thermal deformation away from the top of hot plate (2) and the bottom of close hot plate (2) owing to the temperature difference is too big, takes place until the problem that influences the vulcanizate quality.
Owing to adopted technique scheme, the utility model has been finished satisfactorily and can have been adjusted the two-part temperature of crossbeam, keep crossbeam thermal balance, prevent that thermal deformation from appearring in crossbeam, thereby guarantee the task of vulcanizer vulcanizate quality, and it simple in structurely, compact, rationally distributed provides reliable assurance for raising vulcanizer performance.
Description of drawings:
Accompanying drawing 1 is a concrete structure schematic diagram of the present utility model
Accompanying drawing 2 is sectional side views of crossbeam (1)
Accompanying drawing 3 is that accompanying drawing 2 is A-A profiles
Embodiment:
Accompanying drawing has been described an embodiment of the present utility model, but is not limited to this enforcement.
Embodiment one:
Referring to accompanying drawing, the utility model comprises controller (4), thermal medium input unit (5), temperature survey part (3), thermal medium output device (6), be provided with hot media channel (8) (present embodiment adopts the circuitous hole of " recessed " shape in the same plane) at crossbeam (1) away from the top of hot plate (2), and in respectively being provided with crossbeam (1) local temperature measured hole (9) (present embodiment is each 9 measured hole of top and the bottom) measured hole (9), the top and the bottom of crossbeam (1) lay temperature survey part (3) (present embodiment temperature survey part is a thermistor), controller (4) is put for thermal medium and is closed control assembly (present embodiment is for realizing the microcomputer of team control), and the present embodiment thermal medium adopts superheated steam.2 to make process as follows for it: when vulcanizer is in running order, rising along with hot plate (2) temperature, crossbeam (1) rises near the temperature of lower of hot plate (2) thereupon, and be higher than the temperature of crossbeam (1) away from hot plate (2) top, make crossbeam (1) up and down two parts the temperature difference appears, at this moment, the thermal resistance (3) that is in the two-part up and down temperature exploration hole of crossbeam (1) (9) is transported to the thermoelectric signal in the microprocessor (4), when the temperature difference meets or exceeds certain value, microprocessor (4) then sends an enabling signal to superheated steam input unit (5), heat steam is entered in the thermal cycle passage (8), crossbeam (1) is risen away from the upper temp of hot plate (2), make the temperature difference T of two faces reduce to the permission rated value, after the temperature difference is reduced to the permission rated value, microprocessor (4) sends a shutdown signal to thermal medium input unit (5) again, and the thermal medium input is stopped, and keeps the temperature difference allowing rated value.If the temperature difference becomes greatly again, then repeat above-mentioned work again, thereby realize the thermal balance of crossbeam (1), finish the thermally equilibrated automatic control of crossbeam (1), prevent that effectively thermal deformation from appearring in crossbeam (1).
Embodiment two:
Other is identical with embodiment one, and its difference is that controller (4) adopts balanced bridge.
Embodiment three:
Other is identical with embodiment one, and its difference is that thermal medium adopts deep fat.
Embodiment four:
Other is identical with embodiment one, and its difference is that thermal medium adopts hot water.
