Punch automatic feeding equipment

　　In the automatic feeding production line of the punch press, a variety of equipment is required. In addition to the important function of the feeder (servo feeder, three-in-one feeder, NC feeder), the uncoiler at the forefront of the raw material is also indispensable. Also called material rack. The main function is for automatic uncoiling and rewinding of stamping coils. Today, I will introduce the types of uncoiling materials. The main ones are as follows. Of course, it can also be customized according to customer requirements.

　　1. Hydraulic heavy-duty decoiler: Vertical hydraulic expansion and contraction decoiler is used. It is generally used for the uncoiling of large and medium-sized and heavy materials. If the coil weight is more than 2T, the mechanical equipment recommends that customers choose hydraulic heavy-duty decoiler.

　　The hydraulic heavy-duty decoiler is an improved model of the standard heavy-duty decoiler. It not only changes the form of expansion and contraction from manual expansion and contraction to hydraulic expansion and contraction, but also installs butterfly brakes and pressure arms to avoid loose materials. , While greatly reducing the work intensity, at the same time, improving the stability of the machinery and equipment.

　　2. Heavy-duty decoiler: the vertical manual expansion and contraction decoiler is used, which is mainly used for various medium and thin plate and thick plate coil stamping processing places.

　　Heavy-duty decoiler is also a kind of decoiler that is widely used in stamping automation processing at this stage. It is also called standard heavy-duty decoiler. It is economical in price, has a wide range of applications, and has a high level of customization.

　　3. Light-duty decoiler: It uses vertical fixed rod (CR-100) and vertical manual expansion and contraction (CR-200). There are two models, which are generally used for the uncoiler and stamping of light and thin sheet materials. There are only two types of scrap rewinding, CR-100 and CR-200. The load capacity, material width, and material thickness have very strict limits. If this limit is exceeded, a heavy-duty decoiler must be selected.

　　4. Planar electronic feeder (alias disc carrier): The application is a horizontal disc uncoiling form, which is generally used in high-speed, thin plate stamping processing places, and will not be limited by the inner diameter of the coil. Trackers and swing rods provide control Signal frequency conversion automatic speed control unwinding, fast and stable unwinding speed, convenient feeding (multiple rolls can be stacked at the same time), fast unwinding speed (up to 30m/min), convenient operation, and good stability. Commonly used in high-speed punching applications.

　　5. Double-head decoiler: the symmetrical vertical double decoiler is used for expansion and contraction. The double-head decoiler has two models, whether it is powered or powered. The most common model is non-powered. At this stage, it is generally combined with an S-type leveler and a gear feeder to form a stator and rotor punching production line for silicon steel sheets and EI sheets. And other efficient processing places.
