Two-way compact punch press

Abstract

The invention relates to a two-way compact punch press and belongs to the technical field of press operation. The two-way compact punch press comprises a rack and two oppositely-arranged side extruding devices, each side extruding device comprises a power-assisted mechanism and a power applying mechanism, each power-assisted mechanism comprises a push rod, a bed, a bedplate, a semi-cylinder pushing block and linkage sets, a curved slide chute extending circumferentially along the central line of the semi-cylinder pushing block is formed in each semi-cylinder pushing block, and each linkage setcomprises an upper linkage, a lower linkage, a working rod; each power applying mechanism comprises left linkage, right linkage, a top block and a connecting shaft, one end of the left linkage and one end of the right linkage are commonly hinged to the same connecting shaft, the other end of one of the left linkage and the right linkage is hinged with the rack, and the other end of each of the left linkage and the right linkage is hinged with a die. The two-way extruder has the advantages that has the advantages of simpleness structure, a novel transmission mode is achieved, the transmissioncapacity is amplified by manytimes, and energy consumption is effectively reduced; the three-way compact extrude is compact in structure and small in size, impact vibration and impact noise are reduced.

Description

technical field [0001] The invention relates to an extruder, which belongs to the technical field of press operation. Background technique [0002] The devices currently used in the market for stamping, stretching and extrusion production, such as those used in hydraulic sheet blanking machines, are mechanical blanking machines driven by motors that drive pulleys, pulleys that drive gears to rotate, and gears that drive crank mechanisms. When it is working, not only the impact vibration and impact noise are large, but also the power consumption is high. [0003] The patent number applied by the inventor is ZL201120326594.7, and the name of the invention is a Chinese patent of a hydraulic sheet blanking machine. The lower end of the toggle lever is hinged at the corner of the toggle lever, and the lower end of the toggle lever is hinged on the flat lower support on the machine base plate. One end of the short connecting rod of the toggle booster mechanism is hinged to the cr...

Problems solved by technology

However, after many years of use by the inventor, the following problems have been found: 1. The force transmission of the existing devices for stamping, stretching and extrusion production is uneven; 2. The overall structure of the existing devices for stamping, stretching and extrusion production Restricted and unable to expand; 3. The structure of the existing devices for stamping, stretching and extrusion production is complex
