In the production process of sheet metal stamping, in addition to the unwinding, leveling and feeding of the sheet material roll, it is also necessary to wind up the stamped strip (also called rewinding), that is, the completed finished product. The tape or waste tape is re-wound and packaged for easy handling or subsequent use.
Heavy material rack receipt
At present, the commonly used winding method is to use the same material frame as the unwinding part for winding, so as to realize automatic production. However, this method has obvious disadvantages, that is, it is difficult to tighten the winding, and it is easy to wrinkle and bias. Shifting, the winding method is only suitable for the winding of the waste material belt, and is not suitable for the winding of the finished material belt.
Tensioning machine with material rack
In order to meet the winding of the finished material belt, has designed a tensioning device for the material frame, which is used to complete the reliable and stable receiving. The tensioning machine is arranged on the front part of the material frame (heavy material frame, light material frame, usually heavy material frame) of the metal coil stamping production line, and the tensioning effect is exerted on the plate by the pressing roller, so that the material frame is wound at the time of winding Can be tightened more and does not scratch the web. The tensioning machine adjusts the tensioning force according to the thickness of the winding material through a manual pressure regulating device, and is equipped with a brake device to eliminate inertia, and has a compact structure, simple operation, stability and reliability.
Tensioning receiver
When the tensioning machine is used with the material frame for winding purposes, the stamped material head is first drawn from the punching machine through the pressing roller of the tensioning machine, and the raw material is clamped under the gravity of the pressing roller. Introduce the material head onto the heavy material frame, and hook it on any tile of the heavy material frame to fix the material A type iron; then adjust the pressing force and brake of the pressure device according to the material thickness of the plate. The pulling force of the device is such that the strip of material is stretched; the Jinzhide heavy-duty material frame is started, and the “forward rotation” is operated on the electric box to wind the belt 5-6 times. If the tension is normal, the belt is not When released, it can be processed continuously.
