(2) Heating the die, and enabling the external baking tray to enter a hot pressing die to bake the plate;
(3) The outer baking tray is withdrawn from the hot die;
(4) Closing the die and carrying out hot pressing;
(5) Cooling the die, starting the oil cylinder to extend the punch head out to punch the plate;
(6) Retracting the punch;
(7) Opening the die and taking out the product;
preferably, the infrared baking tray in the step (2) is hand-holdable.
The invention also includes a carbon fiber plate hot pressing and punching device, comprising: the die comprises a fixing plate, a die core, a punch fixing plate, a driving piece and a punch.
The fixed plate, the fixed plate is equipped with fixed plate and lower fixed plate, and is equipped with following all mechanisms between two fixed plates.
The template comprises a male template and a female template, and a mold core is arranged in the template.
The die core is arranged in the die plate and comprises a male die core and a female die core, and a groove for product molding is formed in the die core.
And the punch fixing plate is connected with the driving piece and the punch, and the punch fixing plate is driven by the driving piece to enable the punch connected with the punch fixing plate to punch the product downwards.
The driving piece is locked and arranged on the side of the die plate and is connected with the punch fixing plate through a connecting piece, and the driving piece is used for driving the punch fixing plate to push the punch fixing plate to the direction in the die.
Preferably, the driving member is an oil cylinder.
The punch is arranged on the punch fixing plate, extends into the template and the die core and is used for punching the product.
The hot pressing and punching method and the device thereof provided by the invention not only save the cost of building a station of CNC, but also save the labor cost and man-hour by combining the hot pressing and punching as one process, and the finished product manufactured by the method and the device thereof not only improves the position accuracy of holes, but also reduces the incidence rate of burr conditions compared with the original method.
