Abstract
The utility model discloses a mould for punching holes in plastic otter boards in the production processes of plastic geotechnical grilles. Based on the mould of single row and square punched holes, the utility model is improved into a mould of plural rows and circular punched holes. So the utility model punches holes efficiently; the rips are reduced when the plastic otter boards are drawn and molded into the plastic geotechnical grille, thereby improving the evenness of the plastic geotechnical grille and assuring the using property of the plastic geotechnical grille.
Description
The utility model is a kind of plastics web plate punching die that is used for plastics GSZ production process.
The plastics GSZ is the high strength that foundation stabilization is used in the construction projects such as highway, railway, airport, municipal administration, water conservancy, electric power, mine, harbour, the high performance structures material of low elongation, its production process is earlier plastics web plate (also being plastic parison) to be made in the plastic plate punching, again the plastic wire plate stretching is shaped to the plastics GSZ.When the plastics web plate is made in the plastic plate punching, all be to adopt the punch press punching, at present, the punching die that uses is single, hole side's mould, the die that promptly has only row's punch and quantity to equate, punch and die to design towards square hole or oblong aperture, that is to say that all the punching die that uses is single, square hole punch die now.Its shortcoming is: 1, owing to the square hole or the oblong aperture of dashing, the plastics web plate is when drawing and forming, and the turning in hole often occurs seriously having been influenced the use of plastics GSZs by the phenomenon of drawing crack; 2, owing to be single punching, during punching, longitudinal register between row and row is poor, and the punching breadth is wide more, and longitudinal error is big more, behind the drawn, has also influenced the serviceability of plastics GSZs; 3, owing to be single, once can only dash a round, efficient is low.
For overcoming above-mentioned shortcoming, the purpose of this utility model provides a kind of high punching efficiency, is difficult for producing the crack when the plastic wire plate stretching is finalized the design, and guarantees the plastics web plate punching die of plastics GSZ serviceability.
The purpose of this utility model is achieved through the following technical solutions, on the basis of former single, square hole punch die, improves, and the one, changing towards square hole is the hole, garden, the 2nd, single punching changed into be no less than two row's punchings.
Introduce the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model schematic diagram.
As previously mentioned, the utility model be on the basis of former single, square hole punch die, carry out improved, it is by seat board 1, concave template 2, die 3, upper base plate 4, convex template 5, punch 6, stripper 7, spring 8 etc. are formed down, following seat board 1 is installed on the workbench of punch press, concave template 2 is installed in down on the seat board 1, and die 3 is contained on the concave template 2; Upper base plate 4 is installed on the slide block of punch press, convex template 5 is installed in the downside of upper base plate 4, punch 6 is contained in the downside of convex template 5, stripper 7 is at the downside of convex template 5, and connect with convex template 5, between convex template 5 and stripper 7, spring 8 is housed, is being provided with material-dropping hole 9 on seat board 1, the concave template 2 down.Different is with single, square hole punch die: punch 6 of the present utility model has the garden cylindricality mould of tapering for the bottom, and die 3 is a garden hole shape mould; On convex template 5, be equipped be no less than two rows, every row is no less than 40 punch 6, on the concave template 2 with on punch 6 relevant positions mould 3 identical with punch 6 quantity is being housed.
Like this, slider of punch is every once descending, and promptly punch press whenever dashes once, just can go out the hole, garden that is no less than two rows, makes the plastics web plate of garden hole shape; Simultaneously, increased punching row number, also just strengthened the mould longitudinal size, better effects has been played in the punching location, the plastics web plate that makes the garden hole shape is when drawing and setting, just be difficult for producing the drawing crack phenomenon, and improved the uniformity of plastics earth work grille net network, guaranteed the serviceability of plastics GSZs.Therefore, the utlity model has high punching efficiency, the plastics web plate made from the utility model is not prone to by the phenomenon of drawing crack when drawing and setting, and has improved the uniformity of plastics earth work grille net network, has guaranteed the characteristics such as serviceability of plastics GSZs.
