Auxiliary clamping device of manual press

Abstract

The invention provides an auxiliary clamping device of a manual press. An M-shaped open groove is formed in the front end of a clamping body, supports at the two ends of the M-shaped open groove are first U-shaped supports with forward openings, a support in the middle of the M-shaped open groove is a second U-shaped support with a forward opening, and clamping supporting feet are arranged in thefirst U-shaped supports; a first major arc plate is arranged at the tail end of any clamping supporting foot, and first anti-skid lines are arranged on the arc lines of the first major arc plates; a middle rack is arranged in the middle of the second U-shaped support, and second anti-skid lines arranged at equal intervals are arranged on the front end surface of a pressing end of the middle rack;and the pressing end of the middle rack and the two symmetrically-arranged clamping supporting feet are located at the trisection point of a same circle. The device is reasonable in structure, and theposition of a workpiece is not changed after stress; The clamping force can ensure that the workpiece does not displace or vibrate in the machining process; and the clamping action is fast, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an auxiliary clamping device of a manual press. Background technique [0002] The press is a machine that can make the slider reciprocate and apply a certain pressure to the mold in the required direction. It is a versatile press with exquisite structure. With the characteristics of wide application and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. [0003] The manual press is a simple press that does not require a motor to convert electrical energy into mechanical energy. It uses the principle that the magnitude of the two forces (force point, fulcrum and resistance point) acting on the lever is inversely proportional to their force arms. , and the...
