car press machine

maquinaria bastidor de la prensa  ,hydraulic press machine

This machine is suitable for steel, plastic materials, the suppression process.
This machine has an independent power sector and electrical systems, and centralized control by the button, process action using PLC control. Jog can be realized, the two semi-automatic operation.
The machines work pressure; stroke range may need to be adjusted according to the process. 

1. Performance of Machine and Structure Overview

3.1 Structure of three-bridge and four-column style is adopted by the fuselage: It is composed of upper separator, sliding block, workbench, stand column, master cylinder, hydraulic power system, and electric system, etc. assembly units. The stand column is 45#forged steel with high quality. Surface of four columns conduct chromate finish after the mid frequency hardening.

3.2 Tonnage for suppressing is realized by a piston cylinder with the cylinder block of 45#forged steel. Surface of the piston rod should be dealt with mid frequency hardening. Its hardness is up to HRC38-42 which has a long service life. Main sealing elements of oil cylinder adopt seal ring of imported material to ensure reliable seal.

3.3 Both workbench and sliding block should use T-style groove, so as to arrange moulds.

4. Hydraulic System

4.1 Hydraulic system devices should be arranged on offside of fuselage.

4.2 Hydraulic system should adopt plug-in mounting integrated system with advantages of sensitive motion, reliable work and excellent sealing property, etc.

4.3 Oil hydraulic pump is made up by fuel tank, high-pressure pump, electromotor, and cartridge valve, etc. Fuel tank is welded by steel plate and adopts sealed fuel tank. Its oil absorption and back oil region are divided. Oil tank is equipped with cleanout windows and drain plug, which is easier to clean and change oil. The oil pump inlet port with stopping oil absorption oil filter is to ensure the cleanliness of oil and guarantee the service life of oil pump and valve.

4.4 Hydraulic system with reliable seal is no leakage. It main pipelines adopt flanged joint and are equipped with quakeproof devices(anti-knock pipe clamp).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

5. Electrical Apparatus Control System

5.1 It is equipped with independent electric appliance cabinet. In the cabinet, there is loaded with air switch relay, etc. electric appliances.

5.2 For various alarm signals of press, limit switch and press action can realize motion chain.

5.3 It is equipped with centralized control panel, where arrange necessary action button and option switch.

5.4 It is equipped with a mobile active button.

6. Operating Modes of Press

6.1 Press is equipped with two kinds of operating modes of inching and semi-automatic.

6.2 Stroke of sliding block is adjusted by stroke control device.

6.3 Except for achieving press action of button on the operating station, where it has buttons of “suppressing with two hands”, “return stroke”, “scram” etc.

7. Safety Protection

7.1 Set up scram stop. Once press the scram button, the press will stop immediately.

7.2 In the position of upper and down limit should be equipped with limit switch for sliding block.

8. Work Environment of Devices

Power supply: three phase380V(±5%), 50HZ; operating ambient temperature: 0-40°C.
