Technical field
The present invention relates to a kind of electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine.
Background technology
Existing in the market glass fiber reinforced plastic section bar pultrusion equipment heater all adopts traditional electrothermal tube heating, as Fig. 1 and shown in Figure 2, heating divides three districts, before (A), in (B), the back (C) three sections, according to arts demand, every section temperature is regulated voluntarily, and the section bar raw material enters mould 6 from feeding mouth 7, through after the preheating, heating, typing from discharging opening 8 output products.
As can be seen, there are many drawbacks in this kind mode of heating:
1, this traditional heating mode heat loss is big, and the heat that really acts on mould 6 produces 50% of heat less than heating tube 3, and remaining heat (greater than 50%) is distributed in the air by the last lower clamp 9 of heating tube 3, and energy waste is very big;
2, under heating tube 3 hot soak conditions, easy aged deterioration, service life is short, the maintenance cost height;
3, Lang Fei heat makes environment temperature raise, and has worsened working environment, and the anchor clamps of high temperature also very easily cause burn, scald, and human body is damaged;
4, the heating tube temperature rise is slow, and efficient is very low, and it is not high to regulate sensitivity, is unfavorable for the control of product technology.
Summary of the invention
The object of the invention is to address the above problem, and a kind of electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine is provided, and is specifically realized by following technical scheme:
A kind of electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, comprise mould, die clamp, solenoid and controller, described die clamp comprises two plate clamp bodies, described mould clamping is in the middle of described two plate clamp bodies, described solenoid is sleeved on mould and the die clamp and with controller and is connected, and described mould both sides offer charging aperture and discharging opening respectively.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, it further designs and is, described solenoid has three groups, is socketed on the part that mould (1) and die clamp (2) are gone up corresponding preheating section, bringing-up section and typing section respectively, and is connected with described controller (4) separately.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, its further design be that described charging aperture and discharging opening are arranged on the described line of centres of respectively organizing solenoid.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, its further design be that described controller comprises module is set current strength adjustment module, heat time heating time.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, its further design be that described solenoid skin is enclosed with thermal insulation and not every the material of magnetic.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, its further design be described thermal insulation and be not ceramic fiber paper every the material of magnetic.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, it further designs and is that described die clamp is made by nonmetal exotic material.
Described electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, it further designs and is that described high temperature resistant nonmetallic materials are polyether-ether-ketone.
Beneficial effect of the present invention is:
The present invention adopts the electromagnetism heating only mould to be heated, thermal efficiency height, and energy-saving effect is remarkable; The used solenoid of the present invention itself is done insulation, can not wear out, and maintenance cost reduces greatly; The present invention adopts the electromagnetism heating, has only mould itself to be heated, so can not impact equipment itself and surrounding environment, can effectively reduce room temperature, has improved working environment; Mode of heating firing rate of the present invention is fast, the temperature that can control mould by the quantity or the supply voltage of control coil very easily, and control is simple, flexible, precision is high.

The specific embodiment
Below in conjunction with the specific embodiment the present invention is further specified:
Contrast Fig. 3 and Fig. 4, electromagnetic heating type glass fiber reinforced plastic section bar pultrusion machine, comprise mould 1, die clamp 2, solenoid 3 and controller 4, die clamp 2 comprises two plate clamp body 2a, mould 1 clamping is in the middle of two plate clamp body 2a, mould 1 inside is provided with to squeeze draws processing space (not drawing among the figure), three groups of solenoids 3 evenly are sleeved on mould 1 and the die clamp 2 corresponding three sections temperature controls and are connected with controller 4 respectively, the solenoid skin is enclosed with thermal insulation and not every the ceramic fiber paper (not drawing among the figure) of magnetic, it is polyether-ether-ketone that die clamp 2 adopts nonmetallic materials.Mould 1 both sides offer charging aperture 1a and discharging opening 1b respectively, and charging aperture 1a and discharging opening 1b are arranged on the line of centres of respectively organizing solenoid.Controller 4 comprises and module 4b is set current strength adjustment module 4a, heat time heating time and is connected with power supply (not drawing among the figure).
During operation, machined material is sent into mould 1 from the charging aperture of shaping mould tool 1, meanwhile, set the current strength and the conduction time of passing through solenoid 3 by controller 4, the electric current of controller 4 output high-frequency and high-voltages is to solenoid 3, and solenoid 3 produced magnetic fields when electric current passed through, and produces countless little eddy current when the magnetic line of force is by mould 1 in the magnetic field in mould, mould 1 is generated heat voluntarily, thus the section bar raw material in the hot briquetting mould 1.Thereby the heating intensity and the heat time heating time of mould 1 and inner machined material have been set.Can be according to different the processing stage, as preheating, heating, typing, to heating intensity and the heat time heating time that three solenoids 3 are set separately, satisfy the processing needs after, machined material becomes product and exports from discharging opening 1a.
Die clamp adopts nonmetal exotic material in this scheme, so solenoid only acts on metal die, electromagnetic energy only is converted into the heat energy of mould, and energy resource consumption reduces greatly;
Between metal die and nonmetal mould anchor clamps, install the heat-insulation and heat-preservation material additional, make solenoid be in the normal temperature state at work all the time on the one hand, effectively protected coil, prolonged service life, reduce maintenance cost, made energy utilization rate further improve on the other hand;
Because the use of heat-insulation and heat-preservation material, heat can not pass to die clamp, can not be lost in the air yet, so can not impact environment temperature, anchor clamps also are in the normal temperature state simultaneously, when improving working environment, also can not damage human body;
Aspect temperature control, as required, adjustment control is input to the frequency and the voltage of coil, and speed is fast, and is highly sensitive, makes temperature can better meet the requirement of technology, and efficient has also improved the quality of product when improving.
