LPG Gas Cylinder Production Deep Drawing Machine
This machine is a six-column double-action hydraulic presser, which is suitable for the stretching and drawing of metal sheet.
With an independent power system and electrical system, this machine is under centralized control with buttons. It is controlled by PLC, so inching and semi-automatic operations can be realized.
Both the working pressure and stroke distance of this machine can be adjusted as per the technological needs.
1.Overview of machine structure and performance
1.1 Machine body:
The body is composed of upper beam, stretching slider, blankholder slider, operating platform and upright etc. The upper beam and operating platform form a closed frame through the upright and nut. The body's rigidity and precision retainability are good. The stretching slider and blankholder slider move upward and downward along the upright; the guide sleeve of upright is the composite copper sleeve to enhance the surface allowable pressure and reduce friction; the upright is made of 45# steel with quenching treatment on its surface.
The upper beam, stretching slider, blankholder slider and operating platform are of the steel plate-welded structure. After welding and high temperature annealing treatment, machining is finished. After polishing, there is neither welding slag nor scar in the weld joint so as to ensure the overall body is flat and beautiful in appearance, highly in accuracy and good in rigidity.
1.2 Oil cylinder:
The stretching oil cylinder uses a piston cylinder, which is installed inside the upper beam; besides, the cylinder body is fixed to the upper beam through flanges; the piston rod is connected to the stretching slider by the connecting flange.
The blankholder oil cylinder uses 6 piston cylinders, which are installed around the stretching oil cylinder. The cylinder body is fixed to the upper beam with flange; the piston rod is connected to the blankholder slider with the connecting flange.
The cylinder body is made of high-quality forged steel with uniform material quality; quenching treatment is conducted on the surfaces of all piston rods; oil cylinders will do high-voltage insulation test(1.1 times).
The oil cylinder is sealed with the imported sealing element so as to ensure the reliable sealing performance, no leakage and easy maintenance.
1.3 T-shaped slot
There are T-shaped slots on the operating platform, stretching slider and blankholder slider; the size of T-shaped slot is the standard size for the convenience of users' mould installation.
2.Electrical control system:
Electrical control: the electrical system consists of power part and control part.
2.1 Power part: It controls the main power as well as the start, stop and protection switch of all motors. The tri-star depressurized successively start up is used for the high-power motor. It has small impacts on power grid and strong antijamming capability.
2.2 Control part: the main control console and the moving button station. The main control console can complete the control and operation of all actions of the machine; with high leakproofness, the electrical box can effectively prevent dust invasion.
The main control console is equipped with the operating buttons and function switches of all actions of host machine, the start, stop, alarm, supervision and monitor display so that we can control the working condition of the hydraulic presser at any time.
The moving button station, which is used for the semi-automatic operating, is provided with the two-hand pressing button and emergency stop button etc.
The hydraulic power system, which consists of power control system, all kinds of valves and hydraulic control box etc., provides power to the host machine and realize the control over host machine. The hydraulic system is installed on the right side of the machine body
4.Operating mode of press
4.1 The press is provided with the inching and semi-automatic (two-hand single cycle) operations; the operations can be switched with the change-over switch and controlled concentratedly with buttons.
(1)Inching: A corresponding action will be started by pressing a certain working button and will be stopped by releasing the button; inching is mainly used for machine adjustment. This action cannot be fast.
(2)Semi-automatic (two-hand single cycle) operation: press the two-hand downward button, the press will continuously complete a specified single cycle process.
4.2 The holding time can be set by the time relay.
5.Safety protection measures for device
5.1 Static and emergency stop buttons: In case of any unusual conditions, press the "static" button and the work of press will be stopped completely; press the "emergency stop" button, and both the press and the motor will stop running.
5.2 Overload protection: It is required to provide the hydraulic relief valve in the hydraulic system so that the press won't get damaged due to overload operation.
5.3 There are travel switches in the upstroke and downstroke extreme positions of slider.
5.4 There is a hydraulic supporting insurance loop in the lower chamber of main cylinder.
5.5 Buttons shall be operated with both hands.
5.6 There is a group of photo-electric safety devices in the front side of press, with the protection height of 600mm.
6. Equipment working condition:
6.1 voltage: three phase 380 v (±10%), 50 Hz
6.2 Working temperature: -5~40°C, humidity: maximum 80%
