Profile punching method, symmetrical input type profile punching machine and punching method of punching machine

Abstract

The invention provides a profile punching method, a symmetric input type profile punching machine and a punching method of the punching machine. The profile punching method comprises the steps that symmetric punching is performed at the head and tail ends of a profile to accumulate the hole position errors in the middle position of the profile, and the alignment of hole positions on both sides andthe placement of the overall profile are not affected. Moreover, the punching of the profile is to align the position of the hole positions at both ends, so that the following assembly can be facilitated. Louvers are taken as an example, the louvers of windows are aligned at the hole positions at both ends, so that the threading process is convenient, and almost no threading requirement in the middle part is required, and therefore, a symmetrical punching method is used for accumulating the errors in the middle without affecting the threading processing of the louvers.

Description

technical field [0001] The invention relates to the field of profile processing, in particular to a profile punching method, a symmetrical input type profile punching machine and a punching method of the punching machine. Background technique [0002] Traction, cutting and punching machine is an important traction, cutting and punching equipment, which is widely used in various products of traction, cutting and punching. At present, in the field of venetian blinds manufacturing, the use of traction cutting punching machines has various deficiencies in the calculation of length and punching position. First, the calculation of length and punching position adopts the cumulative calculation input method, resulting in cumulative length tolerances. Two inch and metric size input methods, the operation is cumbersome, the third is the calculation of the length is calculated by a fixed ratio (that is, the calculation is based on the diameter of the measuring wheel / metering wheel or t...

At present, in the field of venetian blinds manufacturing, the use of traction cutting punching machines has various deficiencies in the calculation of length and punching position. First, the calculation of length and punching position adopts the cumulative calculation input method, resulting in cumulative length tolerances. Two inch and metric size input methods, the operation is cumbersome, the third is the calculation of the length is calculated by a fixed ratio (that is, the calculation is based on the diameter of the measuring wheel / metering wheel or the fixed number of the circumference), and the correction is based on the addition and subtraction of the length to correct the size. These calculation input methods It makes the use cumbersome and complicated, and there are many scraps of adjustment materials, large errors, and high maintenance costs (the wear of the metering wheel affects the accuracy and requires frequent replacement). This not only wastes a lot of materials, but also increases the cost of manpower and material resources and reduces production efficiency.
