Technical Field

The utility model relates to a die-cut device particularly, relates to a die-cut device of hot sword of multilayer crowded ABS material altogether.

Background

ABS plastics have high strength, light weight, high surface hardness, high smoothness, easy cleaning, stable size and high creep resistance, and are suitable for electroplating. ABS plastics are widely used in industry, and are often used for manufacturing shells, boxes, parts, toys and the like. ABS plastic extrusion products are mostly plates, bars, pipes and the like, and can be subjected to hot pressing, composite processing and model manufacturing.

When current die-cut device is carrying out hot sword die-cut to multilayer crowded ABS material altogether, hot sword is not good to the unedged banding effect in product edge, and the intermediate level of multilayer material altogether has powdered thing to precipitate out, causes the product to exceed standard at the client side granularity. Meanwhile, because the distance between the cutting edge of the cutter and the bottom plate is too long, multiple layers of materials cannot be well compressed, and edge sealing of the product section is not facilitated.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a die-cut device of hot sword of multilayer crowded ABS material altogether, the effectual product section banding effect of having solved is not good, the problem that product granularity exceeds standard.

Therefore, the utility model provides a die-cut device of multilayer crowded ABS material fever sword altogether, including the die holder, cutting die and put the thing mesa, cutting die fixed mounting is on the die holder, the cutting die includes the cutter, the template, the resistance wire, interior gasket and outer gasket, cutter fixed mounting is in the template, the cutter is including cutting edge and bottom plate, the structure of bottom plate is "mouth" style of calligraphy, the circumference setting along the bottom plate of cutting edge, interior gasket fixed mounting is in the inboard of cutting edge, outer gasket fixed mounting is in the outside of cutting edge, the cross-section of outer gasket is L shape, the outside of the roof perpendicular to side cut of outer gasket is arranged, the curb plate perpendicular to template of outer gasket is arranged, the resistance wire is arranged along the outside circumference of cutting edge, the resistance wire is located between curb plate and the side cut, it is located the below of cutting die to put the thing mesa.

Further, a reinforcing plate is arranged on the inner side of the bottom plate.

Further, the structure of the reinforcing plate is cross-shaped.

Further, the height of the reinforcing plate is smaller than that of the bottom plate.

Further, the height of the inner pad is equal to the height of the outer pad.

Further, the inner gasket and the outer gasket are ceramic gaskets.

The utility model provides a pair of die-cut device of multilayer crowded ABS material hot sword altogether, multilayer crowded ABS material altogether is placed on putting thing mesa, and fixed mounting is down at the cutting die on the die holder, carries out die-cuts. When punching, the inner gasket and the outer gasket which are fixedly arranged on the inner side and the outer side of the cutter can extrude multilayer materials. The resistance wire that cutter circumference was twined heats the cutter, and the temperature of cutter can carry out thermal treatment to the deckle edge at product edge, makes the deckle edge diminish. In order to ensure the consistency of the edge sealing effect of the product, the heating resistance wires circumferentially arranged on the cutter are uniformly embedded, and the actual temperature is consistent. Because the temperature adjustment of the cutter is based on the temperature displayed on the power supply and the temperature displayed by the power supply is based on the temperature of the temperature sensing points arranged on the cutting die, the deviation can be generated on the actual temperature control, and the adjustment of the temperature parameter of the punching is inaccurate to a certain extent. And delay time is set during punching of the cutting die, so that the contact delay of the cutter and the cut surface of the product is short time, and the edge sealing heat treatment can be carried out on the end surface of the product.

The utility model provides a pair of die-cut device of multilayer crowded ABS material hot sword altogether, the effectual product section banding effect of having solved is not good, the problem that product granularity exceeds standard.
