Analysis on the development of winding machine equipment manufacturing industry

The continuous emergence of many high-end intelligent devices has promoted the development of the industry, from winding machines to intelligent robots, which are the products of world scientific development and have evolved in four aspects for the equipment manufacturing industry.

People's production equipment has gone through a long period from the original development trend of stone and stick to manual special tools, and then the development trend has become driving force. The contemporary special tools and machinery have already had the function of CNC machine tools, which is the prototype of fully intelligent production equipment and another milestone development trend of people's production equipment. For example, the appearance of automatic winding machine means the direction of the development trend of winding machine to intelligent system. In recent years, the function of intelligent system of automatic winding machine has been further increased, which has greatly improved the function and efficiency of winding machine. It can be said that the expansion of electronic computer control system, network technology and mobile phone software provides a material basis for the intellectualization of winding machine.

Rapid prototyping technology is a kind of production and processing method in recent twenty years, and it is a significant progress in divergent thinking of production and processing technology. Composite paper, polymer, metal powder, heat-resistant alloy, composite porcelain and forging sand are selected as raw materials for production and processing. The use of electric heating and laser to complete the modeling design of prototype parts greatly shortens the development and production cycle of the whole machine. It is not only used to manufacture mechanical parts prototypes and sand cores, but also enters the related fields of three-dimensional art body shaping and human medical bionic parts (such as bones and joints) manufacturing. This is the latest product of computer science, new material science and new energy science. In this field, many universities and private enterprises actively invest in our country, and the products developed are technically difficult and have entered the advanced ranks in the world.

Structural changes in tools and equipment are not uncommon. For example, the machine tool has a "parallel structure", which is completely different from all traditional machine tool structures. The traditional machine tool structure is a series structure, that is, the machine tool structure moves along three coordinate lines according to Cartesian coordinates, rotates around these three coordinates, and is stacked in series in turn to form the relative motion trajectory of the required tools. All structural geometric precision errors, force transmission and stiffness loss will form a series accumulation and become a fatal weak link. The CNC lathe with series structure moves the spindle bearing head to complete the production and processing posture according to the multi-bar structure and other fitness exercises in the indoor space. Compared with the series structure, the series structure has a series of key advantages, such as simplicity, higher bending stiffness and stronger dynamic characteristics. There are many elite teams in China all over the world who will do scientific research in these fields. How to overcome the accuracy error and expand the application field is a difficult problem to be overcome.

The traditional machining process system is nothing more than turning tool, milling cutter, boring tool, drill bit, broach, grinding wheel, stamping die and pressing die. And all these tools are just entities with certain hardness. Later, oxyacetylene high-temperature cutting method appeared, and electric energy discharge machining method, electrochemical machining method, laser machining method, electron beam machining method, ion implantation method, lithography method and so on appeared one after another. Until recent years, high-pressure water jet machining method (commonly known as "water knife") belonging to "cold energy" and "soft medium" appeared with a brand-new attitude, and cooperated with multi-coordinate numerical control technology in the trial production of new products in automobile industry.
