Summary of performance characteristics:

This machine is suitable for the metal shaft parts extrusion molding (forward extrusion , reverse extrusion,and Precise finishing etc.); Also suitable for pressing of materials of plasticity, such as stamping (must set up the buffering device) curved flanging sheet drawing, etc

This machine is independent of the hydraulic system and electrical system, and USES the button common control, which can realize adjustment and semi-automatic two operating modes. The machine working pressure and working stroke can be adjusted according to the technical requirement in the parameter range, has confirmed when rolling, automatic return

Machine conditions of use:

Working environment temperature: 0- 40 °C

Relative humidity: no more than 85% Cooling water temperature: ≤35°C

Power supply voltage: 380±5% 50Hz

Altitude: not more than 1000 m

Hydraulic system using medium: 46 # anti-wear hydraulic oil

The main structure and function is introduced:

1,This hydraulic press by the host, hydraulic system, electrical control system and auxiliary parts

2,The host part of the fuselage, main cylinder ,cylinder of pack out and Cheng limiter, etc.

3,On the fuselage by beams, the slider, workbench, pillar, lock nut, etc.

- -- the upper beam, the slider, the workbench

On beams, the slider, work by Q235 A steel plate welding and become, and the deformation analysis to ensure its rigidity, welding using advanced co2 gas shielded arc welding, to deal with the stress after welding, the slider in the middle of their body, it is connected with main cylinder plane; Slider there plane processing T slot (T slot and center distance size should be confirmed by the customer), you can use the t-slot bolted to the fixed mould; Sliding block with a guide sleeve, with four pillars installation, guarantee the slider orientation precision, good rigidity, good accuracy stable, slider has the very good rigidity, can satisfy the requirement of cheng is suppressed.

- --pillar

Pillar of 45 # steel material refined processed, after cutting, grinding, hardening, chrome plating and other working procedures, enhance the pillar surface hardness and wear resistance, to ensure that the column surface strain. Between slide block and columns with column guide bush, rely on the pillar as the guidance to do up and down.

4,The main oil cylinder of machine is piston cylinder, nominal pressure is realized by the main cylinder, and oil cylinder connected with the slider. Oil cylinder is installed on the frame, through the oil cylinder lock lock, the piston rod surface of wear-resisting, oil cylinder are chooses import packing seal, long service life, reliable sealing performance.

5,The machine ejection cylinder as the piston cylinder, ejection cylinder installed in the workbench. Mother and workbench fixed, by big lock (DingGang design should consider convenient dust and dust) on the surface of the piston rod wear processing, cylinder selects the import of seal sealing, long service life, reliable sealing performance

6,Cheng limiter:slider and ejection piston stroke position adopt proximity switch control, easy to adjust

7,hydraulic system:The oil hydraulic system is to produce and distribute work unit, and make the host various action for steel weldments, tank adopts closed structure equipped with a filter in the cabinet, box wall open hole is for cleaning tank; Equipped with level gauge, fuel tank is equipped with the integrated body above pump power plant such as the machine using the main hydraulic components in the hydraulic system

8,Hydraulic system is made of Y series motor after coupling drive YCY14-1 B series axial piston pump for the hydraulic system pressure oil

Domestic YCY series constant power is used in the main oil pump axial plunger pump, the pump is the biggest characteristic as the system pressure, flow rate is proportional to the reduced, keep constant power, effectively save energy

9,The hydraulic integrated control valves:Integrated hydraulic control valve with domestic two-way cartridge valve centralized control, with regulating the reversing pressure unloading support fast speed conversion overpressure protection function on the main cylinder inferior vena control block with secondary antiskid blocks falling device and relief valve, when the slider stops at any position, the device automatically shut down, to ensure the reliability and security of the sliding block; When its inferior vena closed due to valve piece of card to death, the bypass valve plays a role of oil discharge in a timely manner, to avoid safety accident

Safety pressure: hydraulic system is equipped with safety valve, overflow automatically when oil pressure more than the set value, and send out alarm signal

10,prefill valve:Charging valve installed on the top of the main oil cylinder, when slider depend on the weight of rapid downward, oil pump to do not timely supply of the main oil cylinder cavity, the cavity on the main cylinder form a negative pressure suction liquid valve open the main valve, make the oil flowed inside the liquid cylinder main cavity, so as to achieve the slider fast downward speed requirements, when the slider on the way back, control the oil first open small drain valve core, make on the master cylinder cavity after pressure relief, and then open the liquid valve the main valve, make the master cylinder cavity on the oil back into liquid box, again through the return pipe into the tank

11,Electrical system:The entire electrical system is divided into dynamic part and control part

12,Driving parts :Using three phase four wire system ac 380 v power supply, By the automatic air switch circuit breaker thermal relay contactor and drive the oil pump use of three-phase squirrel cage induction motor, the Y - starting, safe and reliable

13,Controlling parts :Control part: is composed of main console and a mobile work station, the main console is placed on the host on the right side, floor, mobile work station can be placed around before and after the machine is easy to operate the location of the electric cabinet is made of cold rolled steel plate production, electrostatic spraying, the internal relay with PLC programmable controller and other control components on the front panel control button and function switch motor start-stop button parts monitoring indicator and counter move work station is mainly used for semi-automatic operation, with both hands button operation on its return and emergency stop button, etc

In the electric control cabinet is equipped with lighting and ventilation equipment, electrical control cabinet with good sealing, can effectively prevent dust intrusion

Control unit: adopting PLC programmable controller control

Operation mode: both inching semi-automatic operation mode

Working style: constant pressure repression and the limit of pressing one of two ways

14,Optional configuration

Remove the ejection cylinder:

Users in the machining process without ejection process can select this option to remove ejection cylinder

Traverser:

Moving workbench is forward type, installed on the workbench plane, the cycloidal reducer sprocket drive make it on the slide guide out forward, convenient for mold and the workpiece

Above is optional configuration, id you need, please mark it with “√”
