Demolition machines display models with cutters, coal mining equipment modelers

Background of the project

In this case, the model of an anchor cutter, customised for a mine equipment manufacturer, is required to have more than 90 per cent structural reduction and complete the industrial character of the mine. Focus on key details such as box structure, axial link and blast protection design, while ensuring the accurate presentation of enterprise brands.

Production processes and processes

Data acquisition and modelling

• Based on the customer's overall speed-retarder, three-dimensional laser scans were used to access critical dimensions such as the French positioning surface

• Specially marked sub-wells such as cable interfaces, garters, etc.

• Design an asymmetrical profile with internal structure of input axes and boxes

2. Metal component construction

• Box cast：

  • Use of disapprove model precision casting

  • Keep the face intact on the non-present side

  
  

• Axis processing：

  • 42CrMo Alloy Steel Control Car Slashed

  • Key slot bit cutting process

  
  

3. Functional components restored

• Bomb protection interface：

  • It's plasticized in rubber protection.

  • Internal copper cores can be drawn for demonstration

  
  

• Hanging system：

  • Cast stainless steel rings.

  • The screw connects to the pine-proof mark.

  
  

Selection of materials

1. Subject Materials：

   • Box: HT250 ash cast iron

   • End cap: 6061 Aluminium

   • Tightware: 12.9-class alloy steel

2. Protective materials：

   • Cable protection: flame retardation rubber

   • Seal: Fluorine rubber O ring

IV. Surface treatment process

1. Metal treatment

• Box handling：

  • Spray cleans the cast surface.

  • Underground paint uses epoxy-rich zinc paint.

  
  

• Axis processing：

  • Ultra-precision necks (Ra0.2)

  • Non-workface blackout

  
  

2. Painting process

• Main Colour Spray：

  • Underground paint: 80 m epoxy

  • Flour paint: PUR Project Red (RAL 3020) Three-bread

  
  

• Marking：

  • The company Logo uses UV tablet printing

  • Warning marking wire printing

  
  

3. Industrial qualitative performance

• Add seal tape marks to the surface.

• The bolts make light tool scratches.

V. Presentation of system design

1. Lighting systems：

   • 45° Slash LED spotlight

   • Surgical profile inside the section

2. Interactive function：

   • Rotable input axis demonstration

   • Disable cable connections

3. Protective measures：

   • Steeled glass arc shield

   • The static display.
