Structure And Working Principle of Sheet Stamping Hydraulic PressUpdate:2022-01-13     Hits:199
Sheet Stamping Hydraulic Press, also known as sheet stretching machine, is divided into four column sheet stamping hydraulic press and frame sheet stamping hydraulic press from the fuselage structure. There are two types of moving thin plate stretching hydraulic presses; according to the different stretching workpieces, hydraulic pad stretching, lower top cylinder stretching, die stretching and other forms are commonly used. Sheet metal drawing hydraulic press is suitable for various stamping processes such as drawing, bending, forming, blanking, blanking and flanging of sheets. It is used for the manufacture of various containers and large-scale covering parts for automobiles, as well as the molding of non-metallic materials.

The control system of the double action sheet stamping hydraulic press has three working modes: adjustment, semi-automatic and continuous circulation. The hydraulic control system uses a cartridge valve manifold. The high-pressure pump adopts the inclined axis variable pump, and is equipped with hydraulic oil filtration, heating and cooling systems. The electrical control system adopts programmable logic controller, various fault alarm indicators and infrared light curtain controller of non-contact safety protection control device. According to user needs, it can be equipped with a lower hydraulic pad, a mobile worktable for a punching device, a punching buffer device, and a grating safety device. This machine has an independent power mechanism and electrical system, and adopts centralized control, which can realize manual and automatic operation modes. The working pressure, pressing speed and stroke range can be adjusted, and can complete ejection, without ejection, and stretching. There are three kinds of automatic cycle of process, there are two kinds of molding process of constant pressure and fixed stroke to choose from.

Features of double action sheet stamping hydraulic press:

1. The fuselage of the double-action thin plate stretching hydraulic press adopts a four-beam four-column structure. The fuselage is composed of upper beam, tension slider, edge holder slider, workbench, column, etc. The upper beam, column and workbench are connected by locking nuts and adjusting nuts to form a rigid frame;
2. The slider moves up and down, guided by the column. The surface of the column is plated with hard chrome to improve wear resistance and ensure that the column will not be strained.
3. Upper beam: It adopts steel plate welded structure, and adopts high temperature annealing treatment to eliminate welding stress. The upper beam is where the master cylinder is installed.

4. Stretching slider and blanking slider: placed in the middle of the double-action thin plate stretching hydraulic press body, it is a steel plate welded part, and high temperature annealing treatment is used to eliminate welding stress. There are T-slots on the lower plane.

5. Workbench: Steel plate welded parts are used, and high temperature annealing is used to eliminate welding stress, and an additional workbench and hydraulic pad device are installed on it.

6. Oil cylinder: The main oil is arranged in the upper beam; the cylinder body is fixed with the upper beam through the flange, and the piston rod is connected with the tensile slider through the connecting flange. The cylinder block is made of high-quality carbon steel to ensure uniform material; all piston rod surfaces are plated with hard chrome. The oil cylinder adopts imported material sealing elements to ensure reliable sealing performance, no leakage and easy maintenance.
7. Guardrail: The double-action thin plate stretching hydraulic press is equipped with safety guardrails to ensure the safety of maintenance personnel in the future.
8. Operating system: The double-acting thin plate stretching hydraulic press adopts PLC programming system to realize automatic and semi-automatic operation modes to switch freely, which is convenient for equipment maintenance; the operation speed of the equipment and the pressure of the main cylinder can be adjusted arbitrarily; it can meet the process of fixed schedule and constant pressure during production Require.
9. Hydraulic oil tank: shot blasting, high-pressure vacuuming, and three new technologies for dough clearance.
10. Electrical control system: low maintenance cost, low failure rate, and greatly improved economic benefits.
11. The hydraulic control system of the double-acting thin plate stretching hydraulic press adopts a plug-in integrated system, which has reliable action, long service life, small hydraulic impact, and reduces the connection pipeline and leakage points.
12. Computer-optimized structural design, the four-column structure is simple, economical and practical; the frame structure has good rigidity, high precision and strong anti-eccentric load capacity.
