Rolling device

Abstract

The invention discloses a roll punching device. The device comprises a rack and a first roller unit and a second roller unit which are arranged on the rack in a rotatable mode. The rotation axis of the first roller unit is parallel to the rotation axis of the second roller unit. The first roller unit comprises a first rigid wheel and at least one punching pin arranged on the first rigid wheel. The second roller unit comprises a second rigid wheel and a flexible layer surrounding the outer rotation surface of the second rigid wheel. A plate to be machined is arranged between the first roller unit and the second roller unit and can be subjected to roll punching through the matching of the punching needles and the flexible layer. The device has the advantages that female dies are omitted, the cost is reduced, exchanging of the female die is not needed, and accordingly, the labor cost is reduced; during roll punching, synchronous rotation of the punching pins and the female dies is not required, so that a matched synchronous mechanism is omitted, damage to the punching needles is prevented, and assembly costs are saved; during roll punching, unloading is convenient, roll punched waste can fall into an unloading tank as long as the unloading tank is arranged below the waste; the accuracy is high.

Description

technical field [0001] The invention relates to a rolling flushing device. Background technique [0002] The metal rolling device in the prior art includes a frame, a first roller unit that can rotate on the frame and a second roller unit that can rotate on the frame, the rotation axis of the first roller unit and The axes of rotation of the second roller unit are parallel. The first roller unit includes a first rigid wheel and at least one punch pin located on the first rigid wheel, the second roller unit includes a second rigid wheel and at least one die located on the second rigid wheel, the punch Needle and die fit. During processing, the board to be processed is placed between the first roller unit and the second roller unit, and the board to be processed is punched by the cooperation of the punching needle and the die. It has the following disadvantages: 1. For each type of hole to be processed, a punch needle and a die are required. On the one hand, the cost is hig...

Problems solved by technology

It has the following disadvantages: 1. For each type of hole to be processed, a punching needle and a die are required. On the one hand, the cost is high; When punching, it is necessary to ensure that the punch needle and the die rotate synchronously. On the one hand, a transmission mechanism is required, such as a gear mechanism to connect the first roller unit and the second roller unit to ensure that the two rotate synchronously, which increases the cost. On the other hand, even if the matching The transmission mechanism may also have a slight difference in angular rotation, which will damage the punching needle or die; 3. When rolling punching, it is inconvenient to unload the material, and it needs to be equipped with unloading equipment or manual unloading; 4. Low precision
