Embodiment 1
[0019] When the CNC punching machine is used: punch holes with a diameter of φ10 on the iron plate, the hole spacing is 20mm, the number of holes is 1000, the usual punching speed is 180 times / min, and the time required to complete the punching is 1000÷180≈5.56min. The stamping speed of the machine tool is 280 times / min, and the time for stamping is 1000÷280≈3.57min. Using this machine tool saves about 2 minutes and improves the efficiency by 55.6%;
[0020] In the usual stamping process, if the stamping method is single punching, each time the punching is completed, it is controlled by the single punching end signal, and the proximity switch 3 and the corresponding cam 3 are valid. The completion of the secondary punching is controlled by the nibbling stop signal (40HZ), the proximity switch 6 and the cam 6 are valid, and the rest are analogous to complete the punching work.

The invention belongs to the field of numerical control and relates to a control structure of a frequency conversion type numerical control punch. The control structure comprises a proximity switch bracket A, proximity switches B, a spindle C and cams D. The control structure is characterized in that six proximity switches B are installed on the proximity switch bracket A; six cams D are installed in the positions of dead point signals on the spindle C; the cam 1 corresponds to the proximity switch 1 in the position of the feeding signal; the cam 2 corresponds to the proximity switch 2 in the position of the single punching finish signal; the cam 3 corresponds to the proximity switch 3 in the position of 50HZ step punching stop signal; the cam 4 corresponds to the proximity switch 4 in the position of 30HZ step punching stop signal; the cam 5 corresponds to the proximity switch 5 in the position of 40HZ step punching stop signal; and the cam 6 corresponds to the proximity switch 6 to form a control structure. The control structure has the following advantages: the control structure can realize automatic switching at multi-stage speed, energy conservation, soft start and step punching under the condition that the step is within 35mm, overcomes the defects of low speed and efficiency, improves the working efficiency, is preferred and ideal for the manufacturers and is bound to be well received.
Description
Technical field: [0001] The invention belongs to the field of numerical control, and in particular relates to a control structure of a variable frequency numerical control punching machine. Background technique: [0002] At present, there are many types of CNC punching machines, and the working methods of conventional CNC punching machines are mainly divided into the following types: [0003] 1), single punch: complete punching at one time, including linear distribution, circular arc distribution, circular distribution, and grid hole punching; [0004] 2) Continuous blanking in the same direction: use the method of partial overlapping processing of rectangular molds, which can process long holes, trimming, etc.; [0005] 3), multi-directional continuous punching: the processing method of using small molds to process large holes; [0006] 4) Nibbling: using a small round die to continuously punch arcs with a small step; [0007] 5) Single forming: one-time shallow drawing ...
