The crimping machine is composed of a frame, an automatic lifting mechanism and an automatic hemming mechanism, and is characterized by a threaded clutch welded on the frame. The main shaft is divided into five sections, three straight sections, and two threaded sections. There are three rotating rods distributed at 120 degrees. The rotating rod has a roller at one end and a roller at one end. The edge mechanism works, and the entire hemming process is completed automatically. The utility model has the advantages of simple operation, flexible use, low cost and high efficiency. Working principle: Through the high-speed rotation of the workpiece, the upper and lower sides of the workpiece are squeezed and deformed to form the effect of curling
The shearing line, as the finishing equipment in the strip production workshop of the cold rolling mill, performs trimming treatment on the strip. The purpose is to ensure the width of the strip, and the second is to cut off the edge defects of the strip. Usually, the width of the cut waste is 5 to 25 mm, and the cut waste needs to be collected and processed. Depending on the thickness and material of the strip, the equipment used for collection and processing is also different. For strips with a thickness of less than 3 mm, the strips have good toughness, and a crimping machine is usually used to roll the scrap into a relatively solid scrap roll. For strips with a thickness greater than 3 mm or relatively brittle, the scrap edges are usually treated by shredding.
The working process of the edge crimping machine: The waste edge cut by the disc shears enters the waste edge pit, and then the waste edge is manually inserted into the slit at the end of the reel, and then the pressure roller is pressed down by the oil cylinder, the motor is started, and the reel rotates. The waste edge is wound on the reel. With the continuous increase of the waste edge coil diameter, the pressing roller is continuously raised. When the limit is reached, the proximity switch that detects the coil diameter sends a signal to control the curling machine to automatically stop and send out the unwinding signal. . Operate the roller cylinder and the reel moving cylinder in turn, lift the roller of the crimping machine, pull out the reel, and push the ejector plate by operating the pusher cylinder to push the waste into the waste basket below the outlet of the crimper.
The general structure of the crimping machine is similar, including the reel moving device, the transmission device, the pressing roller device, the pushing device and the wire arranging device. Whether or not to install a cable arrangement is determined according to the positional relationship between the axis of the reel and the centerline of the unit. When it is parallel, it is generally not required; when it is vertical, it must be arranged.
