Description

Metal wire high-speed continuous production line

technical field

The invention relates to a metal wire production line, in particular to a high-speed continuous metal wire production line.

Background technique

At present, in the processing of metal wire in many welding rod manufacturing enterprises, there are generally problems of low production efficiency, low product quality pass rate, low operating safety factor, poor working environment and high labor intensity, and continuous production cannot be realized. These six This aspect has become a technical bottleneck and obstacle that seriously restricts the further development of enterprises. Its specific content is:

1. Low production efficiency. Insufficient straightening ability and unreasonable shearing process are the two main reasons for low production efficiency that cannot match the production capacity of the wire drawing machine. Taking the production capacity of the wire drawing machine as 4 times of the straightening and shearing capacity as an example, 1) The original straightening equipment has a low speed, which makes the frequency of high-frequency straightening insufficient; the number of hole dies (straightening blocks) is 4 sets, which is relatively small And the length of the hole mold is too short, so that the number of low-frequency straightening and the effective straightening length are insufficient. 2) The shearing speed should be at least 750 wires/minute, while the original shearing speed is only 220 wires/minute (take a metal wire with a diameter of 3.2mm and a length of 350mm as an example). The direct cause of the low shearing speed is the combination of cam type punching and signal feedback scaling, which makes it difficult to increase the shearing speed.

2. The pass rate of product quality is low. 1) The frequency of high-frequency and low-frequency straightening of the hub is insufficient, resulting in poor quality of wire bending or twisting. 2) The combined method of cam punching combined with signal feedback and fixed length is used for cutting. Flying stabs, double knives and short heads are the most likely quality problems to occur.

3. The operation safety factor is low. During the conveying process of straightening and shearing raw materials, frequent manual operations pose potential safety hazards. Since the production capacity of the wire drawing machine is much higher than the straightening and shearing speed, the drawn metal wire must be manually unloaded and transported to the straightening and shearing equipment for operation, and it is very easy to cause the wire to hit the operator during unloading body, resulting in work-related accidents.

4. Poor working environment. The secondary pollution of dust and noise damage the physical and mental health of workers. 1) The noise of a single machine based on the traditional process principle of cam-type punching has reached 80 decibels. When multiple machines of this type are operating at the same time, the noise in the workshop is huge, which can easily cause damage to the auditory system of workers. .

5. High labor intensity. Straightening and shearing raw material transportation and metal wire sorting and handling are all manual operations, which is the direct cause of high labor intensity. 1) The low-efficiency operation of the straightening and shearing equipment is extremely inconsistent with the high production capacity of the wire drawing machine, requiring workers to frequently and repeatedly unload and load materials between the two. 2) The cut metal wire also needs to be manually grabbed, checked and then stacked in the storage hopper.

6. Continuous production is not possible. From wire drawing to straightening, cutting and collecting, there is no continuous production between the processes, and it has been cut off many times by humans, so the degree of automation is low.
