Background technique
Large size special-shaped aluminum honeycomb product traditional manufacturing technique method is to use platform or molding die bag press mold pressure, for
The smooth and length and width dimensions product in 3m and 2m respectively is generally heated with hot press and is press-formed.And the large scale portion of abnormity
Part, general press can not be suppressed, and can only fit on forming worktable or molding die after product sizing, utilize bag press mold pressure
Forming certain pressure makes product curing molding.Because used bonding agent is generally dual-component polyurethane structure glue, theory is solid
Change temperature at 10-60 DEG C, and the workshop temperature of bag press mold pressure is room temperature, product curing time need to adjust according to the variation of temperature
Curing time, during annual May~September, technique curing time is generally for 24 hours.Existing vacuum bag pressing molding device does not have generally
Standby heating function, for room temperature at 2 DEG C -10 DEG C, general curing time requires 48h or more, but when room temperature is lower than 2 DEG C or less in winter
When because adhesive curing it is relatively difficult, cannot the pressure production of batch bag, serious limit product is delivered process by this period, while under low temperature
Molding product adhesive curing is incomplete, causes unstable product quality.Because winter temperature is lower, conventional bag presses combination process molding
When aluminum honeycomb product, curing time greatly prolongs product at room temperature, causes production efficiency low, seriously affects delivery process.Together
When, vaccum-pumping equipment long-play, power consumption is big；Product solidification not exclusively, causes properties of product unstable under low temperature.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, a kind of vacuum bag that heating efficiency is strong is provided and is pressed into
Type device, to reduce the pumpdown time, improving production efficiency and quality.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows: a kind of vacuum bag pressing molding device, including
Workbench and bag press mold, the bag press mold can be tightly connected with workbench, be formed between workbench and bag press mold for treating
The seal chamber of shaping workpiece progress forming processes；Carbon crystal heating film and heat transfer are successively equipped on the workbench from the bottom to top
Plate.
It is designed using such structure, is equipped with carbon crystal heating film and heat transfer plate on workbench, when molding, workpiece to be formed
It is placed on heat transfer plate, the heat that carbon crystal heating film generates can be passed to well workpiece to be formed by heat transfer plate, effectively reduce pumping
Vacuum bag presses time, improving production efficiency.
Further, the heat transfer plate includes metal heat transfer plate.
Further, the heat transfer plate includes aluminium sheet.
Further, the heat transfer plate with a thickness of 0.1-5mm, preferably 0.3-2mm.
Further, temperature controller when further including, temperature controller is electrically connected with carbon crystal heating film when described.
Further, the carbon crystal heating film is embedded in bench top.
The vacuum bag pressing molding device of the utility model is particularly suitable for the preparation of large scale or special-shaped aluminum honeycomb product.
In the utility model, carbon crystal heating film is set on workbench or molding die and assists heating, in use, can pass through
When temperature controller automatically control bonding agent solidification temperature and time.Microcrystal in carbon crystal heating film is under electric field action, largely
Carbon crystal micel generates " Brownian movement ", and phase mutual friction and collision between carbon molecules generate a large amount of thermal energy, to realize electric energy to heat
The conversion of energy.The temperature difference is formed between carbon crystal heating film and product or air, the heat generated according to Heat transfer law, carbon crystal heating film
Amount passes to the low product of temperature or ambient air, to improve formed product temperature.It inputs in the electric energy of carbon crystal heating film, surpasses
The electric energy for crossing 69% has been converted to thermal energy and the electric energy more than 30% has been converted to far infrared radiation energy, in this dual heating
Under principle, make product around: the speed 1. to heat up is faster；2. the heat absorbed is more sufficient, formed product temperature is quickly improved.
In addition, carbon crystal heating film has various width and thermal power specification, length can be cut randomly according to power, while its flexibility is good,
Thickness is thin, is easily tightly attached to various special-shaped product surfaces, can change with workbench or mold surface shape and change, convenient-laying and
It uses.Automatic Temperature Control when utilization, first according to product size and moulding process requirement, heating power needed for calculating, selection
Appropriate size power carbon crystal carbon fiber heating film, is configured forming temperature in advance, recycle automatically control heating temperature and
Time further increases heating efficiency.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) compared to traditional vacuum bag pressing molding device without heating, the present apparatus solves bag under low temperature and presses composite caking agent
Slow curing and the incomplete disadvantage of solidification, can effectively reduce the Vacuumizing bag pressure time, promote production efficiency and quality；
(2) carbon crystal heating film heating efficiency is high, while product flexible bag moulding region forms closed environment, and temperature is scattered and disappeared less,
Electricity is high to thermal energy conversion and utilization rate；
(3) device of the utility model is easy to operate, greatly improves production efficiency under low temperature in winter, greatly reduces product
Curing time on forming worktable or mold reduces vacuum compressor long-time pressure maintaining runing time, reduces energy consumption.
