    Wanxin company to explain to you the slitting machine transmission maintenance skills:

    For friends who purchase and use small vibration slitter for the first time, although the slitter is one of the more stable machines in the current industry, according to incomplete statistics, the failure probability of the slitter is far lower than the average of the failure probability of other machines in the industry, but then again, although the failure probability is relatively low, it does not say that there will be no failure. Driving may be easier to learn and master. However, while learning and mastering skills, many users lack experience in the maintenance of the roller, or even ignore it. The harm of doing so must be clear to everyone, in the early stage of buying the machine is not to see what is different. Manufacturers generally have a one-year warranty, which is also a targeted time. The slitting machine has not received regular maintenance for more than 1 year, and the probability of failure is relatively large during the following period. However, the warranty period has passed, such as the occurrence of large damage and failure, its maintenance costs are to be borne by the user himself. It can be said that the life of a machine that is regularly maintained is twice as long as that of one that is not used with care.

    Due to the vibration effect of the vibratory roller, it brings some public hazards to the surrounding environment and human body, which limits the secondary use of the vibratory slitting machine. It is not appropriate to use vibratory rollers for compaction in densely populated areas, dangerous housing areas, near buildings equipped with precision instruments and the bridge deck of highway Bridges. In addition, for the impact of vibration on human health, the vibration slitting machine with poor vibration reduction effect is not welcome.

    Another important trend in the development of intelligence is that random computers will be widely used in compaction machinery.1: used to carry out work. Process monitoring, machine technical status diagnosis, alarm and fault analysis. Artificial intelligence agents will greatly improve the maintenance of machines and accelerate their modernization.

    Briefly understand the open line automatic control device system which several forms of expression

    First of all, we must understand the basic knowledge of the opening line, the opening line is the abbreviation of the unwinding, leveling, cutting, palletizing production line, its main task is to straighten and flatten the steel plate into a roll and then cut into different lengths according to the needs of the product, the code is stacked after loading and shipping.

    At present, most of the Kaiping line adopts automatic control, and the control devices used are as follows:

    [1] Programmable controller PLC, PLC anti-interference ability is strong, stable and reliable work, there are many open lines using PLC control.

    [2] Industrial control machine, it is commonly seen in large open line flying shear control.

    [3] The open line of the counter is usually simple shear positioning, which is difficult to achieve some special requirements put forward by users. Analysis of Kaiping line production process control process, the ordinary 8-bit single-chip microcomputer can be competent, mainly to solve the two problems of anti-interference and positioning accuracy.

    [4] Single-chip microcomputer, which is especially suitable for industrial control microcontrollers, is widely used in many fields such as automobiles, machine tools, and home appliances. Practice has proved that as long as the SCM application system solves the anti-interference problem, compared with industrial control machines and PLC, it has many advantages such as low cost, flexible output form, and common faults can be handled by users themselves.

    [5] On the open line, the length of the workpiece is measured by accumulating the number of pulses output by the pulse encoder. Due to mechanical inertia and other factors, the encoder will be reversed for a short time during the starting and braking process, so the counting circuit should be reversible. If the plate running speed is very high, hardware counting can be used, and in general, software counting can be used.

    How to maintain the uncoiling levelling and shearing production line
    Number of views:43    2023-08-21

    The production line is used to uncoil, strip and reel the coil material of different specifications into the coil material of the required fixed width size to be used in various stamping production lines. The production line has reasonable layout, convenient operation, high degree of automation, high production efficiency, high working accuracy and moderate price. It can process all kinds of cold rolled, hot rolled coil, silicon steel plate, stainless steel plate, color plate, aluminum plate and all kinds of metal plate after electroplating or painting. Widely used in automotive, agricultural vehicles, containers, home appliances, packaging, building materials and other metal plate processing industry. The production line is mainly used for loading trolley, uncoiling machine, slitting machine, trimming machine, shearing machine, stacking device and so on. At the same time, it is equipped with swinging intermediate bridge, traction device, deviation correction device, CNC feeding and measuring device. This production line is an automatic coiling processing equipment integrating machine, electricity, liquid and gas.

    The uncoiling levelling and cutting production line should detect the interface signal. That is, the principle of this detection method is to check through programmable inspection, such as some control system prompts the signal light and the exchange of lights between each other, and do a simple analysis to check the fault place. The main characteristics of the hydraulic plate rolling machine motor are high speed, small transition inertia, easy to start and brake, high conditioning sensitivity, generally high-speed hydraulic motor output torque is not large, so it is also known as high-speed small torque hydraulic plate rolling machine motor, the basic type of low-speed hydraulic plate rolling machine motor is radial piston type. The coil is rolled according to the parameters of the uncoiler rules. The thickness of the coil is 20mm, the length is 2500mm, and the yield limit of the coil data is less than 250Mpa. When the main drive stops, the lifting of the upper roller, the tipping return of the overturned bearing and the cocking of the upper roller can be carried out.

    By measuring the actual thickness and width of the strip through uncoiling, and comparing with the accuracy curve of the thickness meter and width meter, it can be checked whether the thickness meter and thickness and width meter involved in automatic control are normal, and whether the strip thickness and width control are within the standard. With the development of steel distribution industry and sheet metal industry, users have higher requirements for the flatness of the length cut strip in the cross-cutting uncoiling and flattening production line, this trend is particularly obvious in the sheet uncoiling and flattening production line. When determining the main parameters of the straightener roll diameter and roll distance, it is necessary to meet the requirements of the strength of the straightening roll for the large thickness of the strip, and the requirements of the straightening effect for the small thickness of the strip, as well as the strength of the universal coupling connected to the straightening roll and the strength of the journal.
