Prevent that tooth trace breaks cutting device of cross cutting piece
The invention relates to a processing jig of a die cutting piece, in particular to a die cutting device for preventing a tooth line from breaking the die cutting piece.
The die-cut product is widely applied to the industrial fields of the electronic and electrical industry, the automobile manufacturing industry, the flat panel display industry and the like, and particularly applied to the products of layered thin materials in the preparation process, such as insulating materials, shockproof materials, heat-resistant materials, adhesive materials, dustproof materials, shielding materials and the like, which all need to be processed and manufactured by the die-cutting technology. The die-cutting product has a wide application range, is widely applied to high-tech products such as electronics, electric appliances, instruments and meters, communication equipment, digital products, medical instruments and the like, and plays different roles in different products.
In some electronic products, the requirements on the shapes of die cutting piece products are different, the die cutting pieces are often required to be bent, a row of tooth lines are generally arranged in front of a grinding tool knife in the conventional processing method, if the products are required to be bent in the actual use process, a row of pre-folding lines are required to be arranged at the bending position, the pre-folding lines are called the tooth lines for short, the conventional tooth lines are generally formed by pressing the tooth line die in a mould, but the tooth line die additionally arranged generally needs to be matched with the cutting die, the height and the cutting edge position need to be designed and calculated accurately, and the tooth line traces are often too shallow, so that the tooth line effect cannot be achieved, or the tooth lines are too deep, and the die cutting pieces are broken, and other undesirable products are generated.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a safe and reliable die cutting device for preventing a toothed line from breaking through a die cutting piece.
The purpose of the invention can be realized by the following technical scheme: the utility model provides a prevent cutting device of tooth line breaking cross cutting piece, includes the workstation, the feeding subassembly of workstation front portion setting, the mould subassembly that the middle part set up, the material subassembly of pressing that the rear portion set up, wherein the mould subassembly include cope match-plate pattern and lower bolster, the lower bolster on be equipped with down gib block and cutting board, the cope match-plate pattern reciprocate along the guide pillar, its characterized in that, the cutting board on be equipped with die-cutting rule and tooth line sword, the tooth line sword be with the marginal tooth disconnection of die-cutting rule to polish and get rid of the blade point and form.
The cutter point position of the tooth line cutter is of a plane structure, and the height difference between the tooth line cutter and the die-cutting rule is 1-3 mm.
The distance between the die cutting knife and the toothed line knife is 3-30 mm.
And one side of the upper template is provided with an ejector rod, and an ejector pin at the bottom of the ejector rod is over against the positioning hole at one side of the lower template.
The feeding assembly comprises a five-rod plate, a material pressing strip seat, a feeding flat pressing strip and a feeding support plate, one end of the five-rod plate is rotatably connected onto the feeding support plate, the material pressing strip seat is movably arranged on the five-rod plate, and the feeding flat pressing strip is arranged on the feeding support plate.
The pressing assembly comprises a roller seat and a roller arranged on the roller seat, and the roller seat is fixed on the roller seat plate through a pressure spring support plate.
And a material pressing pair roller is arranged behind the roller seat.
The rear part of the workbench is provided with a dragging flat plate.
Compared with the prior art, the invention has the following advantages:
1. the invention directly cuts off the cutting die to be used as a tooth line die, has high consistency, low cost and easy processing and formation, only needs to polish the blade which is used as the tooth line die after being cut off to be smooth, so that the blade can not break a die cutting piece in the die cutting process, and the polishing depth is controllable, thereby avoiding the problem of over shallow processing tooth lines.
2. The five-rod plate is arranged at the feeding hole and can rotate around the end of the feeding support plate, so that the die-cutting piece adapting to different materials and thicknesses can be fed by different tensions, and meanwhile, the material pressing strip seat can move on the five-rod plate to adjust the die-cutting piece adapting to different materials.
3. Set up the ejector pin on last mould to the cross cutting piece is after cross cutting and the tooth line of beating, fixes a position through the thimble on the ejector pin, so that get into follow-up material subassembly of pressing and carry out the roll extrusion and rectify, avoids easily bending products such as plastics, silica gel to produce unnecessary crease, avoids simultaneously to steep flexible products such as cotton and produce the fold.
