Change Machine Hydraulic Relay
 The current upender pertains to a hydraulic servomotor upender transforming machine, in particular for large parts flip perspective, from the discipline of welding automation technology and equipment.
 In the assembly and production of machinery and equipment, often need to move large parts flip positioning, large parts very bulky, if manpower to flip would be very difficult, requiring specialized upender turning machine provides a relatively large work force to complete flip.
 In modern community, stainlesss steel inside the building marketplace is more and more utilized, producing large metal framework should rely on modern day machinery and devices to complete. Hydraulic Relay upender switching machine is dedicated to the H-ray welding production series for big horizontal metal workpiece 180 ?? change of mechanical equipment.
 presently on the market frequently used chain hoist tipper, this upender converting machine functions by utilizing two stores fixed on the big workpiece, upwards grip among a chain, in order that the rotation in the workpiece to achieve turn area. This composition is fairly complex reversing machine in use, there are many problems. In the inversion process, because the use of chain pull bow I, chains in direct contact with the workpiece, the workpiece is easy to damage; Meanwhile, the workpiece turning speed is unstable, especially flip the workpiece from the horizontal position to the upright position, in an upright position flip instantaneous fast, improper operation prone to accidents.
Because the trip chain hoist is limited to large-sized workpiece 180 ?? in need after two flip, first flip down the workpiece by 90 ?? and then Flip once again,  In the H-beam welding production line using horizontal chain hoist tipper. Flip is often because the operator did not notice the chain hoist stroke position, the workpiece has not flipped to 90 ?? to the limit position when it had dropped to reverse flip the workpiece.
 similar overseas reversing machine production line complicated structure, large area, high costs, so basically tend not to use in the united states.
SUMMARY OF THE INVENTION
 The item from the present upender would be to get over the above mentioned deficiencies, thereby providing a hydraulic servomotor upender switching equipment, straightforward framework, straightforward procedure, continuous converting the workpiece, the workpiece will never create damage; improve the effectiveness from the personnel, lowered personnel effort high intensity, low priced and high effectiveness of your comprehensive reversal of your workpiece function.
