Recently, Hunan Jiangbin Group built a gasoline engine piston production line with advanced domestic standards. The completion of this line has enabled Jiangbin Group to enter Changan Automobile's supporting system and realize strategic cooperation with BAIC Holdings, Yunnei Power, Dongan Power, and so on. Entering the middle and high-end gasoline engine piston market, a new basic platform has been built. It is understood that Jiangbin Group has long been committed to the research and development and manufacture of middle-to-high-end diesel engine pistons. The development of pistons for gasoline engines is conducted under the conditions of existing key resources. It has always been in a state of low efficiency, high cost, and unstable quality. Far from adapting to the needs of the market and users. To this end, the company is actively exploring new ways to develop medium-to-high-end gasoline engine pistons in batches, proposing development ideas for “stronger bodies (middle and high-grade diesel engine pistons) and expansion of two wings (medium and high-grade gasoline engine pistons)â€. In particular, since 2010, Jiangbin will enter the mid- to high-end gasoline engine piston market, speeding up the adjustment of products and market structure as one of the “seven adjustments†of the company. In 2011, Jiangbin Group, in conjunction with the ongoing production capacity of Phase II and Phase III technology transformation projects, formally established the first high-grade gasoline engine piston production line that reached the domestic advanced level in early September. The current production line is under intense debugging. By then, it will form a monthly production capacity of 40,000 and an annual production capacity of 400,000 to 500,000 gasoline engine pistons. The production line is mainly used for the production of the company's own design, with independent intellectual property rights of Beijing Automotive's piston engine new products. The completion of this line will be the next step into Changan Automobile's supporting system, and will realize strategic cooperation with BAIC, Yunnei, Dongan, etc., and then fully enter the medium-to-high end gasoline engine piston market and build a new basic platform. It is reported that Jiangbin Group has specialized in producing engine pistons and other components for nearly 40 years. It is the professional manufacturing company with the earliest introduction, the most complete technology, and the best digestion and absorption technology in the domestic piston industry. One with wear-resistant insert ring, the first internal cold oil gallery, the first graphite spray, the first shaped pin hole, the first drum-shaped ellipse, the first combination, the first pendulum, the first An electron beam welds the piston. The company has assets of 410 million yuan, more than 1,000 sets of modern high-precision numerical control equipment, annual output of medium and high-grade engine pistons 3.8 million, the company and Guangxi Yuchai, Shandong Weichai, Hangfa, Chongqing Cummins, Nanjing Iveco and other domestic more than 20 companies Well-known companies have established stable support and important partnerships. Non-woven special equipment accessories
Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.
Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.
The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.
Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.
