Abstract
The invention relates to a hot press. The hot press has the advantages of simple structure, good use effect, low potential safety hazard, and effective ensuring of the material use intensity. The hot press includes a top seat, a bottom seat, an upper die, a lower die and an upper die driving device, a heat source is arranged in the upper die, the top seat is arranged above the bottom seat, the top seat is connected with the bottom seat through a plurality of guide posts, and the upper die driving device comprises an upper die seat, at least one hydraulic cylinder and at least one hydraulic rod. When the hot press is used, the heat source in the upper die is started, and after the heat source reaches a preset temperature, the at least one hydraulic cylinder cooperates with the at least one hydraulic rod to make the upper die move downward to carry out hot pressing on a material. A gas outlet is opened during hot pressing to release a cooling gas source, so the problems of too low compactness and low strength caused by the over extension of the material in the width direction can be effectively prevented; and the cooling gas flow is ejected at two sides of the forward motion direction of the material from top to bottom, so effective caution and protection effects are realized when the misoperation of an operation personnel occurs.
Description
Technical field
The present invention relates to automobile decorative panel processing equipment field, particularly relate to the improvement of hot press.
Background technology
At present, for the living environment gone from bad to worse, the environmental requirement of people to all trades and professions is also more and more higher.To this, someone is proposed and free of contamination fiber crops, terylene, fiber is pressed together by hot press in automobile decorative panel, makes it have the feature that cost is low, pollution-free, result of use is good.This wherein, for reducing costs, hot press adopts opened type to design usually, but the design of its opened type also brings following problem: one, material is when carrying out hot pressing, is affected by thermal expansion and contraction, material is very easily many at width extend through, and cause density in the middle part of material too low, intensity is defective; Two, wherein the upper and lower mould of high temperature brings great potential safety hazard also to the operating personnel in workshop.
Summary of the invention
The present invention is directed to above problem, provide that a kind of structure is simple, result of use good and potential safety hazard is low, effectively can ensure the hot press of material working strength.
Technical scheme of the present invention is: comprise footstock, base, upper die and lower die and patrix drive unit; Thermal source is provided with in described patrix;
Described footstock to be located at above described base and to be fixedly connected with by some guide pillars between footstock and base; Described counterdie is fixedly connected on the end face of described base, and described patrix to be connected on the bottom surface of described footstock by described patrix drive unit and to be located at above described counterdie;
Described patrix drive unit comprises upper bolster, at least one hydraulic cylinder and at least one hydraulic stem, the end face that described upper bolster is fixedly connected on described patrix is socketed some described guide pillars, described hydraulic cylinder is fixedly connected on the bottom surface of described footstock, and described hydraulic stem is fixedly connected on the end face of described upper bolster.
Be provided with cooling source of the gas and the bottom surface of footstock is provided with some gas outlets in described footstock, some described gas outlets are evenly distributed on the both sides of material direction of advance.
Nozzle is connected with bottom described gas outlet.
Be provided with negative pressure source in described base and the sidewall of base offers some air inlets.
The present invention first opens the thermal source in patrix in use, after reaching design temperature (being generally 180 DEG C-190 DEG C), recycles some hydraulic cylinders and hydraulic stem and coordinates and patrix is moved downward and carries out hot pressing to material.And synchronously can open gas outlet when hot pressing, release place cooling source of the gas is (as CO
2, N
2deng), on the one hand, effectively can prevent that material from upper extending that the long density caused is too low at width (material direction of advance is length direction), problem at the bottom of intensity; On the other hand, cooling blast sprays from top to bottom in the both sides of material direction of advance, can play effective warning, protective effect when operating personnel's maloperation.This case utilizes this simply to improve the effect achieving and avoid potential safety hazard and ensure material strength these two aspects, has extremely strong practicality and splendid result of use.

Fig. 1 is structural representation of the present invention,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the top view of Fig. 1,
Fig. 4 is the upward view of base in the present invention,
Fig. 5 is that the A-A of Fig. 4 is to sectional view;
In figure, 1 is footstock, and 10 is gas outlets, and 2 is patrix drive units, and 21 is hydraulic stems, and 22 is hydraulic stems, and 23 is upper bolsters, and 3 is patrixes, and 4 is counterdies, and 5 is bases, and 6 is guide pillars.
Detailed description of the invention
The present invention as Figure 1-5, comprises footstock 1, base 5, patrix 3, counterdie 4 and patrix drive unit 2; Thermal source is provided with in described patrix;
Described footstock 1 to be located at above described base 5 and to be fixedly connected with by some guide pillars 6 between footstock 1 and base 5; Described counterdie 4 is fixedly connected on the end face of described base 5, and described patrix 4 to be connected on the bottom surface of described footstock 1 by described patrix drive unit 2 and to be located at above described counterdie 4;
Described patrix drive unit 2 comprises upper bolster 23, at least one hydraulic cylinder 21 and at least one hydraulic stem 22, the end face that described upper bolster 23 is fixedly connected on described patrix 3 is socketed some described guide pillars 6, described hydraulic cylinder 21 is fixedly connected on the bottom surface of described footstock 1, and described hydraulic stem 22 is fixedly connected on the end face of described upper bolster 23.Like this, first can open the thermal source in patrix in use, after reaching design temperature (being generally 180 DEG C-190 DEG C), recycle some hydraulic cylinders and hydraulic stem and coordinate and patrix is moved downward and hot pressing is carried out to material.
Be provided with cooling source of the gas and the bottom surface of footstock 1 is provided with some gas outlets 10 in described footstock 1, some described gas outlets 10 are evenly distributed on the both sides of material direction of advance.Like this, synchronously can open gas outlet when hot pressing, release place cooling source of the gas is (as CO
2, N
2deng), on the one hand, effectively can prevent that material from upper extending that the long density caused is too low at width (material direction of advance is length direction), problem at the bottom of intensity; On the other hand, cooling blast sprays from top to bottom in the both sides of material direction of advance, can play effective warning, protective effect when operating personnel's maloperation.
Nozzle is connected with bottom described gas outlet 10.Its principle improving material strength is: material remains on about 180 DEG C usually when carrying out hot pressing, rapid expansion in the direction of the width incited somebody to action by material under high temperature, after opening nozzle, the cooling blast of low temperature (less than 0 DEG C) sprays on the both sides of material direction of advance, i.e. width, the material making to be in widthwise edges is met and is coldly gathered contraction, and to middle part extruding, thus simply, effectively raise the density of material, and then the intensity of material is obtained significantly promote.
In described base, 6 are provided with negative pressure source and the sidewall of base offer some air inlets.Can reclaim the refrigerating gas of ejection, and after this send into again in cooling source of the gas by filtering.
