Row's blade punching device of rectangular-shaped nonmetallic materials
Technical field
The utility model relates to a kind of die-cutting apparatus, and the quick processing device of rectangle nonmetallic materials particularly is provided.
Background technology
Fields such as material extensive uses such as rectangle double faced adhesive tape, insulating trip and electronics, computer, household electrical appliances.Need bonding, electric insulation, high temperature resistantly cover, occasions such as waterproof sealing, absorbing buffering, electronic shield widely apply the rectangle on-metallic article.To the processing mode of this product, traditional way is the size that mould is designed to required product, utilizes the leapfrog of machine to be stamped to form continuously.But, because mould interface is 90 ° of right angles, thus unavoidably can be because interface explosion and cause product bad in punching course, and die life is of short duration simultaneously.Therefore, be subjected to the restriction of mould in punching course, must leave certain spacing between product and product, the spacing minimum also will be at 2mm in the prior art, because the demand of product is very big, the waste that causes so also is very surprising.
Fig. 1 is the traditional work mode, and a is unprocessed raw material, and b is a mould, c is the finished product after the moulding, that is, mould b is made the shape of product and be fixed on the motion bar of die-cutting machine the downward drawing of mould b when raw material a enters, mould rises, machine is leapfrog forward, and mould b presses down cross cutting once more, and the machine leapfrog is given between the product and left leftover bits and pieces of material 4, by prior art leftover bits and pieces of material 4 width are minimum 2mm arranged all, cause very big waste.When particularly the output of product was big especially, waste was surprising.
The utility model content
The purpose of this utility model is to provide a kind of row's blade punching device of rectangular-shaped nonmetallic materials, and of short duration to solve at present the die life of causing because of the product design problem, the fraction defective height is wasted technical problems such as big.
A kind of row's blade punching device of rectangular-shaped nonmetallic materials, comprise the mould that is arranged on the die-cutting machine motion bar, mould comprises the horizontal blade region of horizontal blade composition and the longitudinal knife section that vertical blade is formed, laterally the gap between blade and the blade is the width that needs converted products in the blade region, gap in the longitudinal knife section between blade and the blade is for needing the length of converted products, laterally the length of all blades is identical in the blade region, the length of all blades is identical in the longitudinal knife section, spacing in the horizontal blade region between first blade and last piece blade equals the length of blade in the longitudinal knife section, and the spacing in the longitudinal knife section between first blade and last piece blade equals the length of blade in the horizontal blade region.
In addition, the length of blade is raw-material width in the longitudinal knife section.
Also have, the leapfrog distance of die-cutting machine is the length of mould blade in blade region.
And horizontal blade region is arranged on the front end of longitudinal knife section in the mould, and first blade of longitudinal knife section is near horizontal blade region.The longitudinal knife section is arranged on the front end of horizontal blade region in the mould, and last piece blade of longitudinal knife section is near horizontal blade region.
This device comprises a mould, mould is located on the motion bar of die-cutting machine, on mould, be provided with horizontal and vertical cutting knife, under the work of material, move to mould following time at die-cutting machine, the mould dip mold is cut into slices across, mould rising material travels forward, mould presses down, superimposed cross cutting forms longitudinal section on the basis of slices across, so just has been cut into the fritter of rectangle, when material movement arrives the position cross cutting of vertical cutting knife, horizontal cross cutting is just carried out in the rear end of material, therefore, the every clutch cross cutting of mould is once just finished once laterally and cross cutting longitudinally, and the leapfrog distance of die-cutting machine is the length of horizontal cutting knife.
The utility model is to adopt horizontal cross cutting and long direction die cutting to finish die cutting operation, can not stay leftover bits and pieces of material in the cross cutting process, and, high efficiency, product precision height, and less wastage.

Fig. 1 is the traditional work mode;
Fig. 2 is the mould schematic diagram;
Fig. 3 is the punching press schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described.
See also Fig. 2 and Fig. 3, mould 3 is fixed on the top of die-cutting machine by motion bar, is provided with horizontal blade region 1 and longitudinal knife section 2 on mould 3.In this example, longitudinal knife section 2 is in the rear end of horizontal blade region 1, and laterally blade region 1 is provided with some horizontal cutting knifes 11,12, is provided with some vertical cutting knifes 21,22 in longitudinal knife section 2.Laterally the gap between blade and the blade is the width that needs converted products in the blade region 1, gap in the longitudinal knife section 2 between blade and the blade is for needing the length of converted products, laterally the length of all blades 11,12 is identical in the blade region 1, the length of all blades 21,22 is identical in the longitudinal knife section 2, spacing in the horizontal blade region 1 between first blade and last piece blade equals the length of blade in the longitudinal knife section 2, and the spacing in the longitudinal knife section 2 between first blade and last piece blade equals the length of blade in the horizontal blade region 1.
In addition, the length of blade 21,22 is raw-material width in the longitudinal knife section 2.
In this example, horizontal blade region 1 is arranged on the front end of longitudinal knife section 2 in the mould, and first blade 21 of longitudinal knife section 2 is unlimited near horizontal blade region 1.Certainly, this example is not got rid of yet, and longitudinal knife section 2 is arranged on the front end of horizontal blade region 1 in the mould, and last piece blade 22 of longitudinal knife section 2 is unlimited near horizontal blade region 1.
The leapfrog distance of die-cutting machine is the length of mould blade in blade region.
Embodiment
At first set the leapfrog distance of die-cutting machine, the leapfrog distance is the length of the horizontal blade of die-cutting machine, material enters mould 3 under the drive of die-cutting machine, when material during in horizontal cutting knife district 1 the downward punching press of mould form horizontal strip section, mould upwards separates, die-cutting machine leapfrog forward enters vertical cutting knife section 2, mould is punching press downwards once more, stack is die-cut to the longitudinal strip section on the basis of laterally strip section, laterally with under vertical twice cross cutting forming the rectangular tiles finished product like this, when the material in slices across district enters the longitudinal knife section, the rear end of material enters horizontal blade region, when mould once more to lower die cut, at this moment the product that is cut into of longitudinal knife section 2 be finished product and laterally the material that is cut into of blade region 1 be semi-finished product, die-cutting machine serves as distance leapfrog forward with the length of horizontal blade, and the cross cutting shaping of product is once just finished in the downward clutch of mould in the longitudinal knife section like this.
Though the utility model with embodiment openly as above; right its is not in order to limit the utility model; any person with usual knowledge in their respective areas; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the aforesaid right claimed range person of defining.
