Description

Numerical control punching and punching method using transparent adhesive tape to fix processing materials

technical field

The invention relates to the field of numerical control processing of leather and other materials, in particular to a method for punching and punching leather and other materials by using a numerical control punching and punching machine.

Background technique

The CNC punching and punching machine uses pneumatic components to drive the punch (or hole) to quickly impact on leather and other processed materials, thereby forming holes in leather and other materials. The platen of the CNC punching machine when it first leaves the factory is smooth and smooth. If used improperly, after many times of processing, there will be more hole marks on the platen, which will make the surface of the platen uneven, which will affect the effect and position of the punching hole, and even make the nozzle (or hole) tilt, causing deviation. bit. In order to solve the above problems, the applicant proposed a method of placing cardboard on the processing table to prevent damage to the surface of the table in the previous application, including the following steps: 1) Processing on the CNC punching and punching machine Place at least three layers of cardboard on the platen; 2) Draw the contour line on the top layer of cardboard with a CNC stamping and punching machine; 3) Fix the processing material according to the outline of the line drawn on the top layer of cardboard; 4) Use CNC punching and punching to punch holes The machine performs punching and punching operations. However, there are certain defects in this process method, that is, the cardboard will be damaged during the punching and punching operation and needs to be replaced; the original top layer of cardboard is opaque, and it is inconvenient to replace the middle layer of cardboard, which will reduce the processing efficiency and cause cardboard damage. waste.

Contents of the invention

In view of this, in order to solve the above problems, the present invention discloses an improved numerical control punching method, which can reduce the frequency of cardboard replacement and reduce the consumption of cardboard.

The object of the present invention is achieved in that the numerical control punching and punching method of fixing the processing material with transparent adhesive tape, and utilizing the numerical control punching and punching machine to carry out the punching and punching processing of the processing material includes the following steps:

1) Place transparent tape on the platen, and draw the outline on the transparent tape after fixing;

2) Place 2-3 layers of cardboard at the bottom of the adhesive tape, the total thickness of the cardboard is 1.5-3mm;

3) Fix the processing material according to the outline of the line drawn on the top cardboard;

4) Use the CNC stamping and punching machine to perform punching and punching operations;

5) After processing, holes will be left on the transparent adhesive tape. Adjust the position of the middle layer cardboard by observing the holes on the transparent adhesive tape, so that the holes on the transparent adhesive tape appear on the unbroken position on the middle layer cardboard;

Repeat steps 3-5) to process the processing material until the position of the middle layer cardboard cannot be adjusted, so that the holes on the transparent adhesive tape appear on the unbroken position on the cardboard, then replace the cardboard.

Further, the transparent adhesive tape is PVC transparent adhesive tape;

Further, before step 4), the following steps are also included: adjusting the depth of the processing knife in the non-processing area and the rotation angle of the head knife so that the punching depth does not exceed the bottom cardboard;

Further, in step 3), fix the processing material with viscous material;

Further, step 1) specifically includes the following steps:

11) Place transparent tape on the platen and fix it;

12) Input the trajectory of the contour line on the CNC punching machine;

13) The CNC punching machine drives its paintbrush head to walk, leaving traces of contour lines on the transparent adhesive paper;

14) Use a pen to draw the outline along the outline trace.

The beneficial effect of the invention is that the frequency of changing the cardboard can be reduced, the consumption of the cardboard can be reduced, and the processing efficiency can be improved.

Detailed ways

Preferred embodiments of the present invention will be described in detail below.

1) Place transparent adhesive tape on the platen and fix it;

Input the trajectory of the contour line on the CNC punching machine;

The CNC stamping and punching machine drives its paintbrush head to walk, leaving outline traces on the transparent adhesive paper;

Use a pen to draw the contour line along the contour trace;

2) Place 2-3 layers of cardboard at the bottom of the adhesive tape, the total thickness of the cardboard is 1.5-3mm;

3) Fix the processing material with adhesive material according to the outline of the line drawn on the top cardboard;

4) Adjust the depth of the processing knife and the rotation angle of the head knife in the non-processing area so that the punching depth does not exceed the bottom cardboard; A layer of plastic film keeps the machining hole free of debris;
