Closed punch overload protection device

Abstract

The invention discloses a closed punch overload protection device, which comprises a first fixed seat and an overload detection mechanism, wherein the first fixed seat and the overload detection mechanism are fixed on a rack; one end of the overload detection mechanism is arranged on the first fixed seat in a pivot mode, and the other end is fixed on the rack of a closed punch; the overload detection mechanism comprises a connection shaft and an inverted T-type connection rod; one end of the connection shaft is fixed on a second fixed seat, and the other end is fixed with a connection rod seat; the middle position of the T-type connection rod is arranged on the first fixed seat in a pivot mode through a pivot; one end of the cross bar of the T-type connection rod is hinged with the connection rod seat; the tail end of the vertical bar of the T-type connection rod is provided with a close salient point; the first fixed seat is provided with a close switch matched with the close salient point; and the first fixed seat is also provided with a deformation detecting and displaying instrument which is connected with the overload detection mechanism. The invention has high sensitivity, is practical and convenient, and has low maintenance cost and the like.

Description

technical field [0001] The invention relates to the field of stamping equipment, in particular to an overload protection device for a closed punch press. Background technique [0002] The traditional electromechanical punch press uses the motor to drive the flywheel to rotate, and the punch is driven to move up and down in the vertical direction through the flywheel rotation and inertial guidance to complete the stamping work. The pressure overload of the punch punch is a frequent occurrence, due to overload. The dangers and negative effects caused are also obvious, ranging from scrapping stamping materials to causing machine damage. Therefore, how to effectively realize the overload protection of the punching machine has become a difficult problem in front of the majority of manufacturers. A closed type punching machine overload protection device provided by the present invention is to protect the punching machine when it is overloaded during use. a device. Contents of t...
