45 Degree Cold Forming Elbow Machine CE For Seamless And Welded Elbows

45 degree cold forming elbow machine for seamless and welded elbows

1. Product Presentation

HYLW series elbow is suitable for producing 25-630mm, 1D, 1.5d stainless steel and carbon steel elbow. Cold push elbow machine features: easy to operate, energy saving, environmental protection and other functions. The elbow produced by the elbow machine is suitable for a pipe fitting at the bend of a pipe.Among all pipe fittings used in the pipeline system, the proportion is the largest.Usually the most different material or wall thickness of the elbow selection is different from the other forming process.Now the manufacturer commonly used seamless elbow forming process has hot push, stamping, extrusion and so on.It is divided into hot push elbow machine and cold push elbow machine. The main parameters of the shape of the cold-push elbow are curvature radius R, the section irroundness perpendicular to the curvature radius circle and the wall thickness.The process parameters that affect the shape of the push bend include the material of the blank for push, the shape of the material machine for the mandrel head, the heating temperature and its diffusion, and the advance rate.

The technical requirements
1. General requirements
1) purpose of the equipment and main products processed:
Purpose: mainly used for forming compound bending pipe and hinge bending pipe and other products.
Product features: material: 60Mn, 20#, 35#, 45#, 16Mn, 27SiMn, 12CrMoV, 20G, Q235, Q345;Wall thickness: 5mm-8mm;Pipe diameter D: 130≤D≤220mm;R value: 150≤R≤350mm;Value of Angle value: 90 degrees (50%), 45 degrees (30%), 15 degrees and 30 degrees (20%).
2) equipment structure requirements:
The equipment is required to have the function of automatic feeding. The tube material conveying device (provided by a third party, the details shall be subject to the countersign of the drawing) delivers the material to the feeding mechanism of the hot push elbow machine in an intermittent manner of 60s in the beat, one at a time. After the equipment completes one push, the next push can be carried out without waiting.In addition, in order to make bend down after it took off from the same direction from core mold, not chaotic, blanking end is proposed under the elbow school mould of mold (third party to provide detailed drawings sign shall prevail) material, after artificial adjusting Angle position by transmission system directly sent to the online school school machine, corresponding the blanking end of the cold push bend machine structure must be able to meet the requirements of the job.
3) quality requirements :(refer to performance parameters).
4) work efficiency requirements: 20 hours/day, 26 days/month, the equipment is required to be able to work continuously without downtime, the average working time per month is not less than 700 hours.
5) equipment delivery date: within 3 months after the contract comes into effect.
2. Specific requirements
Main technical parameters of equipment:
1) capacity design: 27,000 pieces/month.
2) production tempo: 60s/ piece, adjustable within 50s-120s/ piece.
3) power supply: 380V, 3P, 50Hz.
4) medium frequency power supply: power: 30 ~ 300KW (digital control, sweep soft start).
5) contactors, fuses, fuses, wiring terminals and other components shall be manufactured by schneider or Siemens, and other electrical components shall be manufactured by domestic high-quality products (such as zhengtai and delixi).
6) when the equipment is shut down, the cooling circulating water pump must be allowed to continue working, and the pump can only be stopped when the temperature of the core die part drops to normal.
7) the equipment can automatically protect and stop working in case of power fluctuation of ±20% or sudden power failure,and ensure normal operation after power supply is restored and restarted.
8) relevant parts of the equipment shall have anti-magnetic and anti-rust functions.Water tanks, pipes, etc. are stainless steel or chrome-plated.
9) the relevant dimensions of the equipment shall be determined in the technical agreement.
10) the key structure shall be processed with high-quality materials, and the material inspection report shall be provided.
11) important purchased parts shall be made of well-known brands at home and abroad, and relevant certificates and operation (maintenance) manuals shall be provided.
12) safe and reliable equipment, simple operation, stable operation, low failure rate.
13) make protective covers, guardrails and warning signs for the parts that are likely to cause injury to operators, and make the safety warning signs comprehensive and eye-catching.
