Abstract
The invention discloses a kind of methods, in particular disclose a kind of hot-press method.The hot-press method is heated and is squeezed to workpiece in the mold of heating, then cooling to carry out cooling sequence progress hot pressing processing to the workpiece in the mould by being carried out to the mold, it is characterized in that, the following steps are included: heating in advance, is moved in, first step hot pressing, it moves out, preparatory heating stepses, are moved in, and second workpiece is moved in second mold of heating；Hot pressing moves out.The beneficial effects of the present invention are: the first preheating step carries out in a juxtaposed fashion with the second heat-press step, and second preheating step carries out in a parallel fashion with the first heat-press step.Shorten cooling time, improves the hot-press method of production capacity.
Description
Technical field
The present invention relates to a kind of method more particularly to a kind of hot-press methods.
Background technique
Hot-forming is a kind of important forming method, but current hot-press molding method, common problem are:
It is suitable for mass production, and cooling time is long, the production and processing time is long, and production capacity is low.
Therefore, a kind of shortening cooling time is invented, the written those skilled in the art of hot-press method for improving production capacity urgently solve
Certainly the problem of.
Summary of the invention
The present invention proposes a kind of hot-press method, the hot-press method in view of the deficiencies of the prior art, invented it is a kind of enough can be with
Shorten cooling time, improves the hot-press method of production capacity.
It is as described below that the present invention solves technical solution used by above-mentioned technical problem:
A kind of hot-press method is heated and is squeezed to workpiece in the mold of heating, then cold by carrying out to the mold
But hot pressing processing is carried out to carry out cooling sequence to the workpiece in the mould, which is characterized in that including following step
It is rapid:
1) heating in advance, heats mold in advance；
2) it moves in, the first workpiece is moved in the first mold of heating；
3) first step hot pressing is heated and is squeezed to first workpiece in first mold of heating, then passed through
First mold is cooled down, thus cooling first workpiece in first mold；
4) it moves out, first workpiece is moved out from cooling first mold；
5) preparatory heating stepses heat the second mold in advance；
6) it moves in, second workpiece is moved in second mold of heating；
7) hot pressing is heated and is squeezed to the second workpiece in second mold of heating, then, by institute
It states the second mold to be cooled down, thus the cooling second workpiece in second mold；
8) it moves out, the second workpiece is moved out from cooling second mold；
9) first preheating step carries out in a juxtaposed fashion with the second heat-press step, and second preheating step and first
Heat-press step carries out in a parallel fashion.
The beneficial effects of the present invention are: the first preheating step carries out in a juxtaposed fashion with the second heat-press step, and described
Second preheating step carries out in a parallel fashion with the first heat-press step.Shorten cooling time, improves the hot pressing side of production capacity
Method.
Specific embodiment
The problem to be solved in the present invention is current hot-press method in the process and cooling time is long, and the production and processing time is long, raw
The problem of producing inferior capabilities.
It is as described below that the present invention solves technical solution used by above-mentioned technical problem:
A kind of hot-press method is heated and is squeezed to workpiece in the mold of heating, then cold by carrying out to the mold
But hot pressing processing is carried out to carry out cooling sequence to the workpiece in the mould, which is characterized in that including following step
It is rapid:
1) heating in advance, heats mold in advance；
2) it moves in, the first workpiece is moved in the first mold of heating；
3) first step hot pressing is heated and is squeezed to first workpiece in first mold of heating, then passed through
First mold is cooled down, thus cooling first workpiece in first mold；
4) it moves out, first workpiece is moved out from cooling first mold；
5) preparatory heating stepses heat the second mold in advance；
6) it moves in, second workpiece is moved in second mold of heating；
7) hot pressing is heated and is squeezed to the second workpiece in second mold of heating, then, by institute
It states the second mold to be cooled down, thus the cooling second workpiece in second mold；
8) it moves out, the second workpiece is moved out from cooling second mold；
9) first preheating step carries out in a juxtaposed fashion with the second heat-press step, and second preheating step and first
Heat-press step carries out in a parallel fashion.
The beneficial effects of the present invention are: the first preheating step carries out in a juxtaposed fashion with the second heat-press step, and described
Second preheating step carries out in a parallel fashion with the first heat-press step.Shorten cooling time, improves the hot pressing side of production capacity
Method.
It should be noted that above-mentioned specific embodiment is exemplary, and under above-mentioned introduction of the invention, art technology
Personnel can carry out various improvement and deformations on the basis of the above embodiments, and these are improved or deformation fall in it is of the invention
In protection scope.
It will be understood by those skilled in the art that specific descriptions above are intended merely to explain the purpose of the present invention, not use
In the limitation present invention.Protection scope of the present invention is defined by the claims and their equivalents.
Claims (1)
1. a kind of hot-press method is heated and squeezed to workpiece in the mold of heating, then by being carried out to the mold
It is cooling to carry out hot pressing processing to carry out cooling sequence to the workpiece in the mould, which is characterized in that including following
Step: mold is heated in heating in advance in advance；It moves in, the first workpiece is moved in the first mold of heating；First step heat
Pressure, is heated and is squeezed to first workpiece in first mold of heating, then by first mold
It is cooled down, thus cooling first workpiece in first mold；It moves out, is removed from cooling first mold
