Problems solved by technology

[0002] Punch presses are commonly used equipment in the field of mechanical processing for stamping and forming parts. At present, the general press industry uses crank or eccentric shaft punch presses. The guide guide is connected, and the entire die height adjustment mechanism of the crank punch press is installed inside the slider, and the slider is directly connected with the upper die. When high-temperature stamping products are required, the entire slider mechanism will heat up and contract, and the slider will produce Deformation, resulting in unstable mold height adjustment accuracy and slider repeat positioning accuracy, so that the accuracy of stamped products cannot be guaranteed, so the current crank punch is not suitable for high temperature stamping

Abstract

The invention discloses a connecting rod punch press, comprising a rack, a crankshaft, a lower slide block, and a crankshaft rotation drive device, wherein the lower slide block is in sliding fit with the rack. The connecting rod punch press is characterized in that an upper slide block is arranged inside the rack; the upper end of the rack is provided with a dynamic balance connecting mechanism of the upper slide block; a first link transmission mechanism is arranged among the crankshaft, the lower slide block and the upper slide block; the rack is provided with an upper slide block adjusting mechanism which is used for adjusting the height of the mold. The connecting rod punch press has the advantages that the upper slide block is arranged inside the rack, the rack is provided with the upper slide block adjusting mechanism which is used for adjusting the height of the mold, and the upper and lower positions of the upper slide block can be adjusted through the adjusting mechanism, thus the height of the mold of the connecting rod punch press is adjusted, meanwhile, the internal structure of the lower slide block is also reduced, the structure of the lower slide block is simplified, the condition that the lower slide block can bear good punching, and does not deform when the connecting rod punch press is used for punching at high temperature is ensured, the punching stability of the punch press and the accuracy of a punched product are ensured, and the connecting rod punch press can be applicable to high-temperature punching.
