Abstract

The invention relates to a metal pressing hydraulic machine, which is characterized in that two columns are connected between the upper beam and the lower beam, a main cylinder and a guide rod are installed on the upper beam, and a backing plate is installed at the lower end of the main cylinder and the guide rod , a pressure column is vertically installed at the lower end of the backing plate, a lead cylinder matching the pressure column is installed on the lower beam, a roller for guiding the lead bar is installed at the upper end of the lead cylinder, and a lead bar plate is arranged behind the lower beam Roller and feeding mechanism. It solves the time-consuming and labor-intensive problem of manually coiling lead bars, realizes the automation of lead bar coiling, greatly reduces the labor intensity of workers, and improves work efficiency; The lead cylinder is equipped with electric heating elements and heat shields around the periphery, which reduces the heat dissipation surface and improves the thermal efficiency; in addition, the invention has the advantages of simple structure and easy manufacture.

Description

technical field [0001] The invention relates to a hydraulic press, in particular to a metal pressing hydraulic press. Background technique [0002] A known structure of a metal pressing hydraulic press is as follows: four columns are connected between the upper beam and the lower beam, a master cylinder is installed on the upper beam, a slider is installed at the lower end of the master cylinder, a pressure column is installed at the lower end of the slider, and a column is installed on the lower beam. There is a heating plate, and a mold (lead pressing cylinder) matching the pressing column is installed on the heating plate. The operation method is as follows: put the heated lead liquid into the mold on the heating plate, then the slide block goes down, pressurizes, and extrudes the lead strip, which is manually coiled. The lead bar produced by the hydraulic mechanism of this structure is completely manually operated, which is time-consuming, laborious, inefficient, and po...
