Headpiece of creasing press for brattice of brattice case

Abstract

The invention discloses a headpiece of a creasing press for a brattice of a brattice case. The headpiece is characterized by comprising a frame body and a heating device and a push type broach device which are arranged on the frame body, wherein the heating device and the push type broach device are sequentially arranged on the frame body in the feed-in direction of a to-be-machined brattice plate on a working table of a creasing press, the position of the heating device is used as a heating station, and the position of the push type broach device is used as a mould pressing station; the heating device comprises a heating body arranged towards the working table of the creasing press from top to bottom, and the heating body is of a long strip shape along the width direction of the working table; the push type broach device comprises a hydraulic cylinder and a push type broach die; and the push type broach die is arranged towards the to-be-machined brattice plate on the working table of the creasing press from top to bottom, the push type broach die is of a long strip shape in the width direction of the working table of the creasing press, and the hydraulic cylinder drives the push type broach die to act. The headpiece is developed according to the characteristic of a thick plastic hollow plate of the brattice of the brattice case, two steps, i.e. sequential heating and indentation pressing are performed, sticking is unlikely to occur, and a prepared indentation has good quality.

Description

technical field [0001] The invention relates to manufacturing equipment for plastic turnover boxes, and in particular to a machine head of a special crease processing machine for coaming boards of coaming boxes. The machine head is the main processing head part of the crease processing machine. Background technique [0002] In the process of wholesale and retail of goods, a kind of coaming box is often used. The so-called coaming box, see the specific structure Figure 9 As shown, it is composed of a tray 1, an upper cover 2 and a surrounding board 3. The surrounding board 3 forms four side walls between the tray 1 and the upper cover 2; As a result, the coaming plate 3 is specifically composed of two parallel and opposite fixed plate parts and two parallel and opposite folded plate parts, and a first crease 4 is set at the corner of the fixed plate part and the folded plate part; A second crease 5 arranged along the longitudinal direction is also provided on the middle par...

AI Technical Summary

Problems solved by technology

[0003] In the field of plastic turnover boxes, the creases of hollow boards are usually made by scoring lines, that is, a line is carved at the creases. This kind of manufacturing equipment and technology is widely used in thin-walled light hollow boards. There are many, but the engraved lines will greatly reduce the strength of the box body, and a major feature of the above-mentioned coaming box is the high load-bearing requirement, and the coaming panels are all made of thick three-layer composite hollow boards (see Figure 10 ), it can be said that it is completely inapplicable to make creases with engraved lines

In addition, people will also think of pressing the creases by hot pressing, but the current hot-pressing crease equipment is developed for real plastic boards, and is used to process thick three-layer composite hollow boards such as coaming boxes , it is easy to damage the surface of the plate, and the production quality is poor
