Cutting and cold roll forming device for a plurality of angle bead nets

Abstract

The invention belongs to the field of cutting and cold roll forming, and particularly relates to a cutting and cold roll forming device for a plurality of angle bead nets. The cutting and cold roll forming device for the angle bead nets is characterized by comprising a locating roll, a cutting roll and a plurality of forming rolls, the locating roll, the cutting roll and the forming rolls are connected in sequence, each forming roll comprises an upper forming roll and a lower forming roll, a plurality of protruding portions which extend outwards and are provided with upper sharp corners are axially arranged on each upper forming roll, a plurality of sunken portions which sink inwards and are provided with lower sharp corners are axially arranged on each lower forming roll, the angle of each upper sharp corner is larger than that of the corresponding lower sharp corner, each sunken portion and the corresponding protruding portion are in clamping connection, and each upper forming roll and the corresponding lower forming roll are in surface contact when clamping is carried out. According to the cutting and cold roll forming device for the angle bead nets, the angle bead nets can be produced at the same time, cost is low, and working efficiency is high.

Description

[0001] technical field [0002] The invention belongs to the field of slitting and cold-bending forming, and in particular relates to a slitting and cold-bending forming device for a plurality of corner protection nets. [0003] Background technique [0004] The corner protection net has changed the traditional method of trimming the inner and outer corners of the wall by hand or borrowing simple tools, shortening the construction time and effectively reducing the construction cost; the anti-collision ability is strong, which can prevent the construction personnel from touching the corners during construction. Create a gap; it also solves the problems of indoor yin and yang angles that are not straight, and is widely promoted in today's architectural circles. However, most of the corner guards currently on the market are formed by stamping, which has slow forming speed and low efficiency. At the same time, the production cost of stamping is high and the structural strength ...

AI Technical Summary

Problems solved by technology

However, most of the corner guards on the market are formed by stamping, which is slow in forming speed and low in efficiency. At the same time, the production cost of stamping is high and the structural strength is low.

During the stamping process, two kinds of public hazards, noise and vibration, seriously endanger the operator, and operator safety accidents occur from time to time; the maximum stamping speed does not exceed 500 times / min, and the production efficiency is restricted; the product will appear shaped Insufficient, poor rigidity, roll line, uneven ridgeline protrusions, napping, tensile strain marks, height deviation of flanging and bending angles, wrinkling, necking cracks, scratches, improper shaping, etc.
