Method for achieving process of on-line punching cold-roll-forming cutting production line

Abstract

The invention discloses a method for achieving a process of an on-line punching cold-roll-forming cutting production line. The method comprises the following steps of providing a material strip into a punching hydraulic station through an uncoiling machine, accomplishing primary machining on shape holes in heads and tails of two products by using a punching die, and subsequently accomplishing primary shaping and material guiding of the products under rotation traction forces of a main motor of a shaping machine set and a shaping die. The material strip is automatically fed into a boss punching station; demanded positions of the products are accomplished on the boss by using a boss punching die; and the material strip further automatically enters a punching hydraulic station; and all procedures of the products are accomplished by using a cutting die. In the primary punching hydraulic station, a secondary punching hydraulic station and the punching hydraulic station, source powers of all dies are supplied by a servo oil pump motor at the hydraulic stations. According to the method, servo motor are adopted for driving oil pumps at the all hydraulic stations, and within the intervals that a shaping machine conveys the materials, the servo motors of the oil pumps at the hydraulic stations can stop working and are intelligently started when power sources are demanded, so that the energy waste is prevented.

Description

Technical field: [0001] The invention relates to the technical field of steel strip cold-bending forming processing, in particular to a method for realizing an online punching cold-bending forming cutting production line process. Background technique: [0002] For the production process of a frame with folded edges or a profile with concave and convex surfaces, nine complex processes such as cutting, punching, multiple stamping, convex platform stamping, hypotenuse punching, and buckle arc stamping are required in the prior art. The process is completed separately, and there are many types of length specifications for frame products, which require larger and longer stamping equipment, resulting in a lot of equipment waste and increased labor costs, and complicate the process and operation. The same product needs to be transferred to different stations many times, resulting in low production efficiency, large production space, serious equipment energy consumption and large en...
