Abstract

The utility model relates to a die-cut mould of high accuracy fixed length. The dragging servo error of the existing punching machine is large (about +/-0.5 MM), and the production requirement cannot be met. The utility model discloses a die-cut mould of high accuracy fixed length installs on material takes transmission path, the material area transmit by the servo motor drive, die-cut mould includes die carrier and lower die carrier, the lower extreme of going up the die carrier sets up cutting needle and pilot pin along material area direction of delivery interval, the lower part center of going up the die carrier sets up the cutting die, under set up down the edge of a knife and lower location mouth respectively in the position of cutting needle and pilot pin on the die carrier. The utility model discloses the distance of the last cutting hole needle of mould and pilot pin is fixed and the error is very little (± 0.02MM), so the material area of cutting out is also the fixed length. The utility model discloses simple structure, convenient to use can improve off-the-shelf quality as supplementary the use.

Description

High-precision fixed-length punching die

Technical Field

The utility model relates to a die-cut mould of high accuracy fixed length.

Background

With the increasing automatic production, the requirements of customers on the cut products are also increased. The production of sheet materials has not been able to meet the demands of automated production by customers. Therefore, it is necessary to design some coil products, and the requirement of the automation equipment on the product spacing is high (generally within +/-0.1 MM). The dragging servo error of the existing punching machine is large (about +/-0.5 MM), and the production requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model discloses shortcoming to prior art exists provides a die-cut mould of high accuracy fixed length, can ensure to produce the product of fixed length, and the error is less, simple structure.

Therefore, the utility model adopts the following technical proposal: the utility model provides a die-cut mould of high accuracy fixed length, its characterized in that installs on material area transmission path, the material area transmit by the servo motor drive, die-cut mould includes die carrier and lower die carrier, the lower extreme of going up the die carrier sets up cut hole needle and pilot pin along material area direction of delivery interval, the lower part center of going up the die carrier sets up the cutting die, under set up down edge of a knife and lower locating hole respectively in the position of just cutting hole needle and pilot pin on the die carrier.

And a blanking port is arranged at the lower part of the lower die frame and communicated with the hole cutting needle and the positioning needle.

The protruding length of the positioning needle is longer than that of the hole cutting needle.

The upper die frame is also provided with guide posts at two ends respectively.

And the two sides of the material belt are provided with material baffle plates.

The utility model discloses the distance of the last cutting hole needle of mould and pilot pin is fixed and the error is very little (± 0.02MM), so the material area of cutting out is also the fixed length. The fixed-length product can be produced by repeating the steps. Simple structure, convenient to use can improve the finished product quality.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A high accuracy fixed length punching die as shown in figure 1 is installed on a material belt transmission path, a material belt 7 is driven by a servo motor to transmit, the punching die comprises an upper die carrier 1 and a lower die carrier, a hole cutting needle 5 and a positioning needle 3 are arranged at the lower end of the upper die carrier at intervals along the material belt conveying direction, a cutting die 4 is arranged at the center of the lower part of the upper die carrier, and a lower knife edge 8 and a lower positioning opening 10 are respectively arranged at the positions of the hole cutting needle and the positioning needle which are just cut on the lower die carrier.

And a blanking port 9 is arranged at the lower part of the lower die frame and is communicated with the hole cutting needle and the positioning needle. The protruding length of the positioning needle is longer than that of the hole cutting needle. The upper die frame is also provided with guide posts 6 at two ends respectively. And the two sides of the material belt are provided with material baffle plates 2.

The working principle of the utility model is as follows: firstly, the material belt is punched to form a hole, then the hole is supported below the positioning needle by dragging the material through the servo motor, and when the material belt is punched for the second time, the material belt is fixed through positioning, and then a new hole is cut. Because the distance between the hole cutting needle and the positioning needle on the die is fixed and the error is very small (+/-0.02 MM), the cut material belt is also fixed in length, and the fixed-length product can be produced by repeating the steps.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
