Sheet Stretch Forming Press for Auto PartsUpdate：2022-05-17 Hits：218
The sheet stretch forming press is a kind of stainless steel stretching hydraulic press, which is widely used. From the tensile structure, it is divided into two types: lower top cylinder stretching and hydraulic cushion stretching. The sheet stretch forming press relies on the fast oil cylinder to generate pressure to complete shallow drawing, forming, flanging, bending, flanging, extrusion, forming, as well as calibration, press-fitting and other operations. Stretching and pressing of aluminum products and forward and reverse stretching of stainless steel products. This sheet stretch forming press is mainly used for stretching and forming of thin plates such as auto parts. It adopts hydraulic pad to stretch and form at one time.
Performance Characteristics of Sheet Stretch Forming Press
1. It has independent power mechanism and electrical system, adopts button centralized control, and has jog and semi-automatic working system.
2. The sheet stretch forming hydraulic press has low energy consumption, high efficiency and novel model.
3. Equipped with safety protection device and automatic counting function
4. The speed control of the second stage of the movable beam: no-load fast, slow working speed, mold-feeding and stretching.
5. The main cylinder and the blank holder have upper and lower limit protection, and the setting of the stroke position is simple, convenient and fast.
6. The working pressure, speed and stroke range can be adjusted arbitrarily within the specified range as required. And can complete the two process methods of upper pressure forming and fixed process forming,
7. In semi-automatic operation, both process modes have pressure-holding delay after pressing and automatic return action.
8. The sheet stretch forming press for auto parts sheet drawing forming is simple in structure, economical and practical. It adopts hydraulic pad stretching process and PLC intelligent control, which has the characteristics of easy operation, high production efficiency, less defective auto parts, and high appearance flatness.
Hydraulic pads, also known as stretch pads, are an important part of controlling sheet metal forming equipment. In addition to considering factors such as one-time investment costs, floor space, and maintenance and use costs, hydraulic pads also need to focus on their performance parameters, such as pressure range , pressure fluctuation, effective stretching stroke, number of strokes, energy curve, position control, cooling function, energy saving measures and the principle structure of the stretching pad, etc.
The sheet stretch forming press for auto parts has two types: top-mounted type and bottom-mounted type. The master cylinder can quickly descend - decelerate and suppress - hold pressure delay - pressure relief return - stop (any position) basic working cycle, and the pressure, speed and pressure holding time need to be adjustable. The ejector cylinder is mainly used to eject the workpiece, which can realize the actions of ejection, retraction and stop.
