Working principle of hydraulic punch

The working principle of hydraulic press: circular motion is converted into linear motion, and the flywheel is driven by the main motor, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to realize the linear motion of the slider. The motion from the main motor to the connecting rod is circular.

Hydraulic punch is the first fully automatic intelligent servo electro-hydraulic compound press in stamping equipment industry. Compared with the traditional punch and injection molding machine, it has made great breakthroughs in mechanical structure, control system and function. The hydraulic punching machine adopts the self-developed double-dead-cycle servo system control mode, which is highly humanized, fully automatic, intelligent and powerful.

Hydraulic press is a kind of press that uses hydraulic cylinder to generate pressure. The hydraulic press was invented by Yue Se Bula Ma Faming of England in 1795 and applied for a patent. After studying the literature about fluid movement at that time, Brama applied his concept to the punching machine.

Classification of hydraulic press:

1, hot forging hydraulic press

Large forging hydraulic press is a kind of forging equipment that can complete various free forging processes, and it is one of the most widely used equipment in forging industry. At present, there are 800T, 1600T, 2000T, 2500T, 3 150T, 4000T, 5000T and other series forging hydraulic presses.

2. Four-column hydraulic press

The invention is suitable for the pressing process of plastic materials. Such as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet stretching, transverse pressing, bending pressing, turnover correction, etc. Four-column hydraulic press can be divided into four-column double-beam hydraulic press, four-column three-beam hydraulic press and four-column four-beam hydraulic press.

3. Single-arm hydraulic press (single-column hydraulic press)

The working range can be expanded, and the stroke of the hydraulic cylinder can be extended by using three spaces (optional), and the maximum expansion and contraction can reach 260 mm-800 mm, and the working pressure can be preset; Cooling device of hydraulic system.

4. Gantry hydraulic press

Machine parts can be assembled, disassembled, straightened, calendered, stretched, bent, stamped, etc., so as to realize multi-purpose of one machine. The workbench of the machine can move up and down, which enlarges the opening and closing height of the machine and is more convenient to use.

5, double column hydraulic press

This series of products are suitable for press-fitting and bending of various parts, stamping indentation, flanging, punching and shallow stretching of small parts; Metal powder products molding and other processing technologies. Adopt electric control, set up inching and semi-automatic circulation to ensure calendering, good slider guidance, convenient operation, easy maintenance, economy and durability. According to the user's needs, the functions of thermal instrument, ejecting cylinder, stroke digital display and counting can be added.
