Pipe forming hydraulic press is also called internal high pressure forming. The three-beam four-column hydraulic press takes the tube blank as the blank, adds ultra-high pressure liquid in the tube blank, and applies axial thrust to both ends of the tube blank to supplement the material. Under the joint action of the two external forces, the tube blank material produces plastic deformation and finally fits the inner wall of the mold cavity.

 Pipe forming hydraulic press andIt is called internal high pressure forming. The three-beam four-column hydraulic press takes the tube blank as the blank, adds ultra-high pressure liquid in the tube blank, and applies axial thrust to both ends of the tube blank to supplement the material. Under the joint action of the two external forces, the tube blank material produces plastic deformation and finally fits the inner wall of the mold cavity. hollow variable cross-section structurepipe fitting forming hydraulic pressThe traditional manufacturing process is to first press and form two halves, and then weld them into a whole, while hydroforming can form hollow structural parts with changes in the cross section of the component at one time. Let's summarize the characteristics of hydroforming.

 

 pipe fitting forming hydraulic pressReduce enterprise quality management, save building materials, process a typical part,pipe fitting forming hydraulic pressThe molding of hydraulic system is 20% ~ 40% less than that of stamping parts, and the weight of hollow stepped shaft parts can be reduced by 40% ~ 50%. It also reduces the number of some parts and moulds, reduces the cost of hydraulic press moulds, and reduces the welding amount of students' subsequent development of mechanical products processing and assembly. Secondly, the strength and rigidity of the four-column hydraulic press are improved, the fatigue strength calculation of the radiator bracket using electronic hydraulic molding has been greatly improved; after that, we are for the cost of common concern. Practical research has proved that the production and operation cost of hydraulic molding is reduced by 10% to 20% compared with stamping parts, and the cost of mold companies is reduced by about 20% to 30%.

 

Each usepipe fitting forming hydraulic pressBefore, check the amount of oil, replenish it in time when it is insufficient, and keep it well lubricated. After power on, move the operating handle to the vertical position and close the oil return port. After starting, the oil of the oil pump enters the oil cylinder and drives the plunger to rise. After closing, the oil pump continues to supply oil. When the oil pressure rises to the rated value, press the stop button. Keep the press in a pressure holding state, the working pressure shall not exceed the rated pressure, and cut off the main power supply when it is stopped,pipe fitting forming hydraulic pressTighten the column nut while working. During the empty test, a 60mm thick backing plate shall be placed on the plate.

 

  pipe fitting forming hydraulic pressPerformance characteristics:

 

1. The equipment adopts prestressed composite frame structure, which is stable and reliable, and has a long service life; the four-column structure is easy to operate, economical and practical.

 

2. Forming technology has two management work and life styles of fixed size pressing and fixed forming force pressing, which can be selected arbitrarily.

 

3. It can be equipped with servo energy-saving system, mobile workbench, mold automatic spraying lubrication system, automatic feeding system and other auxiliary systems.

 

4. It can realize automatic adjustment of pressure, and can realize various movements such as pressure, stable pressure, and reflux.

 

5. Through the selection of the operation panel, not only two molding processes of fixed stroke and constant pressure can be realized.

 

6. It has its own independent power research organization and electrical information system, adopts PLC programmable design controller, and can realize four basic operation and management modes of inching, manual, semi-automatic and full-automatic. It can automatically carry out functional development. Some enterprises with mold cavity oil injection, increase and pressure relief adopt China's advanced hydraulic control engineering technology, and do not need to use manual handles to relieve pressure, thus reducing the complexity of artificial intelligence operation and the rejection rate, increased safety and reliability.

 

7. The machine layout is reasonable, the operation and maintenance are convenient, the work is reliable, the production efficiency is high, and the product quality is good.
