Embodiment Construction

[0024] On-line continuous punching method in cold roll forming

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as image 3 The schematic diagram of feeding is shown, and the feeding direction is from right to left, as shown by the arrows, 3 is a plate, and from right to left are punching die 1 and punching die 2. The distance between the centerline of the punching die 1 and the centerline of the punching die 2 is H.

[0027] Online continuous punching method: first, you need to input the information of the product to be produced: including the notch position on the plate (there is a product between the two notch positions), the number and position of holes for each product, and the distance between the punching die and the notch die H.

[0028] When the punching die equipment is running, after each action of the punching die and the punching notch die, determine the die that will move afte...

Abstract

The invention relates to online continuous punching method and equipment in cold roll forming. The method includes the steps that information of products to be produced is input; in production, after a punching die and a gap punching die act each time, the die which acts after next feeding is finished is determined; the feeding length a of a next hole and the feeding length b of a next gap are calculated according to the length of fed materials and the information of the products to be produced, the two distance values are compared, if the a is smaller, the punching die is the die which acts after next feeding is finished, and if the b is smaller, the gap punching die is the die which acts after next feeding is finished. By means of the mode, the products of various specifications can be produced automatically and continuously.

Description

technical field [0001] The invention relates to the field of cold-bending forming, in particular to a method for continuous punching in cold-bending forming. Background technique [0002] Cold bending (also known as roll bending) forming production line is a material-saving, energy-saving and efficient new technology and new process for sheet metal forming. Its raw materials are coils of steel, copper, aluminum and other materials with fixed width and thickness. Due to the shape limitation of cold roll forming and the requirements of production efficiency, the equipment configuration is usually to feed and punch holes first, then buffer and store materials, and finally form and cut. During this process, the continuity of materials is the main way to improve production efficiency. [0003] For the feeding and punching part, it is necessary to pre-punch the continuous plate into holes of different shapes or pre-treat the plate. figure 1 It is a continuous diagram of products ...
