After longitudinal punching in a circular tube, back to the origin, according to the requirements of the preset program rotation rotating the Angle, again according to the longitudinal hole punching as preset program, back to the origin, so on N times longitudinal punching until completion.The longitudinal punching process and rotation Angle is set separately.Domestic patents to fill gaps in the model technology, especially for the customer of the thick wall stainless steel pipe holes and breakthrough in theory than, for domestic initiative.

Future:                                                                                                                              

a. The TFT HMI (human-machine interface) display, Touch Screen settings, NC control system, precise servo motor positioning, module storage memory function.

b. Structure:Steel plate welded structure

c. Mould replacement: change the die easily without adjusting the dies to reduce the mould damage rate and pipe fittings rejection rate due to the dies setting error. Skilled workers can change the mould within 10 minutes.

d. Punching Category: 1.single hole punching; 2.double hole punching; 3.Isometric hole punching; 4. none- Isometric hole punching; rotary punching.

e. Hydraulic and Servo System:

1. Step-less operation adjustment, hydraulic loops designed with zero load, combined with extremely low frequency oil pump motor, effectively reduced noise, increased motor efficiency and service duration.

2. When the oil cylinder is moving downward, the machine is designed with hydraulic difference driving loops rated at high or low RPM .it is also featured with high speed downward moving, low speed processing and hi-speed position resume .it is available to increase the formation stability of work pieces during puncturing .in addition to increasing the activation speed, it can effectively reduce HP load to save electrical energy.

3. The electrical control system is designed with the human machine interface, range adjustment use digital scale, setting low speed position, floor level position, and operation precise and easy.

4. Cylinder stroke 130mm (can be set), throat depth 300mm,available for forward and backward 150mm moving accessibility. Designed with the Italy-made digital scale with high precision.

Equipment Production Process:                                                                                   

Feed   -    clamp   -    fix position  -     start automatic  -     punch   -  unload

Application:                                                                                                                      

Square tube, rectangle pipe, round pipe, H-bem, I-beam, C-channel, Angle Steel and any other pipe punching, Punch material;all kinds of iron, aluminum, copper ,stainless steel and so on.

Technical Data:                                                                                                                

After feeding, the machine automatic feed material and stamping  according to the preset programs,automatic stop after the preset hole number rushed .Pitch error ±0.1 mm,one person can operate several machines, greatly saves the artificial.The machine can match any mold to achieve different hole shape, both whole hole or half hole.Can meet the square tube, round tube, C steel, U steel, Angle steel, strip plate punching hole, punching letters, embossing process requirement, etc
