Abstract

The invention discloses a mechanical safety device for pneumatic hydraulic cylinder driving and stamping equipment. The mechanical safety device comprises a swinging mechanism and a pushing mechanism used for driving the swinging mechanism to swing to and fro; the swinging mechanism comprises an adjustable support plate which is arranged on equipment body, a curved swinging rod of which one end is rotatably connected with the adjustable support plate through a linkage shaft, and a U-shaped block which is arranged at the other end of the curved swinging rod; the adjustable support plate is provided with an adjustable tension spring seat; the adjustable tension spring seat is connected with the curved swinging rod through a tension spring; the pushing mechanism comprises an adjustable roller frame which is arranged on a rotation prevention clamp plate, and a roller which is rotatably arranged at the lower end of the adjustable roller frame; and the roller synchronously drives the curvedswinging rod to swing to and fro by taking the linkage shaft as a revolving shaft while a lengthening bar of a working piston is pressed downward or lifted upward.

Description

technical field

[0001] The technology relates to a safety device configured for stamping equipment driven by a gas-hydraulic cylinder, in particular to a mechanical safety device for the configuration of stamping equipment used to directly transmit pressure through the working piston rod of the pressure cylinder and act on small workpieces. Background technique

[0002] At present, in the category of stamping equipment, it is especially related to a safety protection for the pressure-transmitting stamping equipment through the working piston rod of the pressure cylinder. Because the body of the pressure cylinder working piston rod transmits pressure, the body of the stamping equipment has a simple shape and structure, which is different from the mechanical transmission stamping equipment. In comparison, under the same working pressure conditions, the working range is large and the external volume is small. In particular, small stamping equipment is still the main production ...
