Full Automatic Seamless Gas Cylinder Hot Spinning Machine

1. Cylinder material: 34CrMo4 (35CrMo), 37Mn, 30CrMo, 45#, 20#

2. Specifications for cylinder

2.1. Diameter range: φ76~180mm

2.2. Length range:330~1100mm (The max length of the tube is 1250mm)

2.3. Thickness range:<10mm

2.4. Weight:<80kg

3. Production speed: < 80s

4. Spindle speed: 260~520 r/ min

5. The way host spindle chuck clamping: Did not appear the axial sliding after clamping , clamping force can be adjusted according to the need. Clamping force ≤180KN.

6. Hydraulic station: molding-bottom device. scraping- bottom device ,sliding-table and chuck device adopt independent hydraulic system. Tank cooling use heat transfer.

7. Electric control parts adopt famous brand products The frequency converter and PLC are adopted in the corresponding products of Delta Electronics.

8. Mould(die) material: 3Cr2W8V.

9. The swing mould to form bottom have water cooling device.

10. The sliding table with scraper (mould) have thickening function .the scraper can run more than once at horizontal and vertical on the basis of setting parameters in the touch screen at any time

11. Location mode of workpiece adopts the back of the positioning for product conformance The positioning length can be manually adjusted according to the requirements .

12. By replacement of the tooling, mould and adjusting the process parameters, can be quickly implemented different specification products.

13. That machine is for bottom forming and bottom pushing. If you want to save cost, you can also use the machine to form the mouth when you change the moulds. But it is inconvenient to change moulds.

Bottom pressing machine

1. The max pressure for bottom pressing: 150Ton

2. The max traveling distance for bottom pressing: 150mm

3. Main structures: the bottom pressing machine consists of the main frame, inner mould driving

and reversing device, auxiliary tightening device, rotating V-frame etc...

4. Main features: machine main body adopts 4-column structure; the moulds are made from

3Cr2W8V; different sizes of cylinder requires different thickness V-frame, sleeves, and inner and outer mould.

5. The max length of the tube can be 1250mm.

The main structure can be seen as above. The machine is used to press the bottom after the bottom is formed. Working process: workpiece will enter the V-frame from last process, mandrel pushing cylinder will push the workpiece to the front by pushing the mandrel, the slide actuating cylinder push the gate to the opening of the mandrel, after that, the oil cylinder push slide block to drive the out-die work,and return after forming the bottom. slide actuating cylinder make the gate open,mandrel-push&pull-cylinder drive the mandrel to reset,then the flip cylinder rise up ,the flip V-rack flips through the flip hinge frame,the last,the workpiece is sent to the feeding rack.
