Product Description
Utility model relates to pipe shut machine necking machine field, in particular relates to a novel process special steel threaded necessary machines. Special thread shut machine necking machine, the pipe about 15mm at the front port for rope about shrinking treatment. GY-300B2 shrink tube machine pipe shut machine necking machine is my factory shut up in the traditional seamless machine necking machine developed on the basis of a new model, the machine uses automatic variable hydraulic design, load time is short, steel shut machine necking machine shrink tube speed, etc., there are three operating mode for users to choose, I plant main products. 1, seamless steel cylinders shut machine necking machine, using one of the forged double-acting hydraulic cylinder, with a buckle pressure, high precision, speed, etc.. Steel body, live game, chrome front cover material 40, for heating, heat, cooling, high-frequency heat treatment, to prevent rupture. Seamless shut machine necking machine superior hardness of the entire cylinder to ensure durable wear and life expectancy.
2, the special deduction shut machine necking machine mold, mold base material is Cr12MoV, quenched and tempered, high-frequency processing, CNC wire cutting, etc. After processing mold hardness of HRC (59 ° -63 °), the mold has to prevent rupture and wear; does not destroy the joint surface of the zinc coating, life expectancy, etc., mold using magnetic installation simple and quick installation; replacement fast, special deduction shut machine necking machine for the patented product.
3, seal, Japan (NOK) imported high quality oil seals, high pressure, high temperature resistance, abrasion resistance, overall life than domestic high.
4, a special deduction shut machine necking variable piston pump is Shanghai, the system pressure 31.5Mpa.
5, the entire hydraulic system adopts Germany Rexroth hydraulic parts series.
6, the surface of the device chassis, high temperature paint, so that the process of using high temperature, wear resistance, corrosion resistance, water and oil, easy to clean.
Steel shut machine instructions:
1, steel machine body is shut the machine working bodies. Pressure set in the cylinder piston reciprocating motion, driven to achieve, so that the front panel of the inner cone sleeve and front sliding plate having an inner sleeve promote symmetrical cone mold base produces radial contraction, pipe shut machine implementation module hose withhold. When the contraction reached the scale is set value, withholding stops automatically change back solenoid valve, hydraulic oil into the open mold cylinder, push the piston reverse movement, steel shut machine die holder under the action of the spring drive module recovery.
2, steel pipe shut machine work will be sent to the corresponding mold conveying mouth, starting motors, pumps, control valves, driven cylinder plunger movement through the wall with a tapered gland, pipe clamp shut machine with the same taper spring pressure head wall, to achieve lamination purposes. Steel shut machine for backward, press sleeve opposite direction, the spring pressure head recovery, the pipes exit out.
