Description
Technical field
The utility model belongs to temperature measuring servicing unit field, more particularly, relates to a kind of isolated plant of assay plate vulcanizer board surface temperature.
Background technology
Vulcanizing press is the equipment of making final rubber, and this procedure is called sulfuration, and it is so that rubber becomes available rubber from the elastomeric compound of greenware condition.Sulfuration is a chemical reaction process, and it need to possess three key elements and rubber could be prepared, and the sulfuration three elements are: temperature, pressure, time.
The vulcanizing press heating part that we use is electric heating system.Its temperature sensor is K type thermopair, and it is experienced temperature and is converted into thermoelectromotive force, exports to the temperature control table.The position of sensor is installed on the rear portion of heating plate.Heating plate has two purposes, and the one, there is electric heating tube inside, and curing temperature is provided; The 2nd, be used for transmitting the pressure that sulfuration needs.
The vulcanizer table top is long-pending to reach 400mm * 400mm, that have even larger.Heating plate has three layers mostly, and last layer is fixedly connected with board respectively with basecoat, descends for preventing the fuselage endothermic temperature, in that to be lined with sheet asbestos heat insulation with the fuselage junction.
In addition, in the prior art, the sulfuration board does not use surface temperature measuring instrument, and the temperature that only shows according to the temperature control table is come vulcanized rubber article, has the following disadvantages:
(1) temperature sensor of vulcanizer is installed in place in the middle of the heating board rear portion, and the temperature value that the temperature control table shows comes from this.Mould horizontal frontal plane size, thickness are different along with different rubber sizes; The factors such as the heat absorption of mould, vulcanizer ambient air flow, ambient room temperature, so that the heat dissipating state of sulfuration board also is among the continuous variation, the mould cavity temperature is lower than temperature control table displayed value, the inhomogeneous situation of rubber state of cure (vulcanization) can occur;
(2) the vulcanizer electrical heating elements is arranged in the heated plate, and in the middle of sensor was positioned at, the temperature that sensor is measured approximately represented zone, centre of sulfuration board, can not reflect the temperature of the whole area of board.Sulfuration board surface temperature has gradient, can cause that the rubber state of cure (vulcanization) is inhomogeneous.
The land surface pyrometer supply is arranged on the market, such as non-contact infrared land surface pyrometer, contact thermocouple land surface pyrometer.They all have the defective that is not suitable for measuring sulfuration board surface temperature.
The non-contact infrared land surface pyrometer, what it absorbed is the infrared light of testee radiation, because infrared light is sightless, in order to allow the user thermometer can be aimed at the mensuration area of testee, this instrument can send a kind of red laser indication light beam.Instructions prompting, the indication light beam must be perpendicular to measured surface, being absorbed of the infrared light maximum of guarantee testee radiation, thus the temperature value of measuring is only accurately, otherwise deviation is arranged.During sulfuration, the mould of tens to twenties cm thicks is pressurized between the sulfuration board, and its spatial altitude does not allow vertically to put into the Infrared Surface thermometer; Testee is metal in addition, and the metal surface can be because smooth finish causes the temperature of measuring on the low side.
Thermojunction type surface in contact thermometer can not guarantee contact point and sulfuration board close contact; The contact point ambient air flows, so that the temperature of measuring is hanged down more than 20 degree centigrade.
Summary of the invention
The technical matters that utility model will solve
Measure inaccurate problem for the vulcanizing press board surface temperature that exists in the prior art by its inner sensor, the utility model provides a kind of isolated plant of assay plate vulcanizer board surface temperature, and it can realize vulcanizing press board surface temperature is measured comparatively accurately.
Technical scheme
Above order of the present utility model is achieved through the following technical solutions.
A kind of isolated plant of assay plate vulcanizer board surface temperature comprises a block plate.Described steel plate side is provided with row's blind hole, the heating plate plane parallel of the axial and vulcanizer board in described hole, and the degree of depth in described hole is the 1/3-1/2 of steel plate width.Adopt the purpose of a block plate to be, can simulate mould under heated condition, sulfuration board and mould are having under the state of natural heat dissipation, measure the temperature of each point of mould inside, in order to regulate the static compensation setting of corresponding temperature control table inside, so that the temperature of mould inside is consistent with the indication of temperature control table.
Further, the number in described hole is 3.The quantity in hole is set to 3 purpose and is, the temperature of three different parts of mould during the simulated determination sulfuration.
Further, the degree of depth in described hole is 1/2 of steel plate width, and the scope of the degree of depth is 90-110mm.
Further, described bore dia is 8mm.Bore dia be 8mm be because the diameter of various sensor diameters, glass-stem thermometer substantially all in 7-8mm.The aperture is excessive, and the heat radiation of hole affects temperature measurement accuracy; The aperture is not as leaving no room, and then the dimensional tolerence of temperature probe external diameter, glass-stem thermometer external diameter can make it be difficult to put into inside, hole.
Further, the upper lower limb in described hole respectively on the steel plate distance of lower limb be 3-3.5mm.This distance is more suitable, if greater than 3.5mm, the steel plate of then simulating mould is partially thick, the indeterminacy of board surface temperature; Less than 3mm, then the pressure of board can make the distortion of thermometric frock.
Beneficial effect
Than prior art, the utility model has the advantage of:
(1) device of the present utility model is provided with in the side of steel plate and is fit to the blind hole that thermometer inserts, the thermometer of assay approval can be inserted in this blind hole, measure the surface temperature of every layer of vulcanizer board, according to the temperature results of using device of the present utility model to record, adjust the static compensation value of temperature control table inside, make it to show that the thermometer demonstration with in the temperature measuring equipment is consistent, the device of the invention has played the effect of calibration temperature control table, has greatly improved the accuracy of temperature control table sign temperature;
