[CN 201820014407.3] Calibration device for cold heading machine
[CN 201820014407.3] Title of a calibration device for cold heading machine: Application number of a calibration device for cold heading machine: CN 201820014407.3 Applicant: Jiaxing Dongyou Hardware Products Co., Ltd. Application Date: 2018-1-4 Patent Type: Utility Model The utility model relates to the field of screw processing equipment and mainly discloses a calibration device for cold heading machine, including a frame on which a vertical straightening mechanism and a horizontal straightening mechanism are sequentially arranged along the steel wire transmission direction, the horizontal straightening mechanism includes several rotating columns arranged on the frame and rotating wheels rotatably connected to the rotating columns. The vertical straightening mechanism includes a driving component, a transmission component and a pressing roller. The frame is provided with a supporting block. The transmission component includes a rotating shaft and a supporting plate arranged on the supporting block. The rotating shaft is rotatably connected with the supporting plate. The rotating shaft is provided with a ring groove, and the sliding block is slidably connected with a sliding rod, the sliding rod is slidably connected to the supporting plate, and a pressing roller is arranged on the sliding rod, and the driving assembly is arranged on the supporting plate for driving the rotating shaft to rotate. The utility model adopts a new mechanical mechanism, and straightens the steel wire through the pressure roller with the runner, so that the friction between the steel wire and the cold heading machine is reduced, the steel wire transmission is accelerated, and the bolt production efficiency is improved.
