Nomenclature of tools for forging

Finishing PUNCHES

Finishing PUNCHES

Finishing PUNCHES
- according to PHILLIPS and POZI standards for hexagonal, square and slotted heads, special PUNCHES to customer's drawings for heading of non-standard hardware. 

    When ordering you must specify the following: 
  • Material of forged metal products (carbon or stainless steel, or others.) 
  • Appearance of the head of the fastener, standard of forged metal products (JIS, ANSI, DIN, ISO, etc.) 
  • The outer diameter and length of the punch DxL. 
  • Coating of the working part of the punch: TiN (titanium nitride), TiCN (titanium nitride carbide), TiAlN (titanium aluminum nitride) or without coating 
  • When ordering non-standard PUNCHES for metal hardware heads in accordance with the drawings of the customer, it is necessary to provide drawings. 

Note: when ordering PUNCHES there is a minimum set of the order, the amount of which depends on the type and size of the ordered punch.

Slugger Punch

    When ordering, you should report the following: 
  • Standard of metal hardware, provide drawings or samples of hardware 
  • Dimensions of the matrix holder installed in the press or in the multi-position machine 
  • The diameter of the wire (blank) 
  • Forged wire material
Cutting matrix

Cutting matrix
When ordering, specify the characteristics of the cutting matrix, material of the processed metal products, matrix sizes, coating of the working surface or detailed drawings of the matrices.

Thread-rolling dies for rolling threads on machine bolts, self-tappers and screws 

    To order thread-rolling dies you should specify:
  • Material of the metal hardware. 
  • Thread type. 
  • Type and standard of the metal hardware, type of the metal head. 
  • Manufacturer and model of thread rolling machine, the size of the fixing plates

Manufacturing of non-standard THREAD ROLLING DIES is possible but only while detailed drawings of hardware are provided.

FACTORS AFFECTING THE TOOL LIFE OF COLD HEADING TOOLS

Cold heading tools life depends on many factors:

  1. The accuracy of the equipment operation (precise feeding of metal, precise blanks cutting, minimum clearance on slides, backlashes, beats and in the transfer mode, all bolts and screws are tightened).
  2. Qualifications of the serviceman, who understands how to ensure the accuracy and clarity of the machine operation.
  3. Quality of metal preparation for cold heading (the stability of the mechanical properties, the stability of the wire diameter).
  4. Quality of applied technological lubricants.

The approximate resistance of main cold heading tools for the production of M22 bolts of 30CrNiMo8 (30HN2MA) steel depending on the length of the shaft portion of the bolt:

  • 0 Position: the plug of flying knife of ВК20КС 20000-30000 kg, the plug of bed knife of ВК20КС 20000-30000 kg,
  • 1 Position: Heading matrix with insert of ВК20КС 40000-50000 kg ejecting punch with insert of Р6М5 50000 kg, ejecting punch of Y10А 5000 kg
  • 2 Position: Heading matrix with insert of ВК20КС 30000-40000 kg ejecting punch with insert of Р6М5 20000 kg, ejecting punch of Y10А 5000 kg.
  • 3 Position: cutting punch with insert of Р6М5 (in the body of matrices unit) 40000 kg cutting matrices of Р6М5 in the body of punch unit 2,500 kg punch ejecting punch of Y10А 20000 kg.

Thread rolling: norms of tool life for further planning tools are traditionally installed after production of at least 100,000 kg.

Tool life of thread-rolling dies is about - 30,000 kg of products, thread rolling fixed dies - 30000 kg.

After determining the real toll life to every detail of cold forging tools, tool replacement is recommended, it goes without saying, it certainly guarantees eliminating the ingress of defective parts in the container with finished products.
