3 must- haves to assess the quality of punches and dies

 

• 

The press brake tooling market is really large, so choosing among the products offered by the many companies can get hard. Which parameters should be considered to choose the best punches and dies? Which ones can satisfy your bending requirements most efficiently? In this article, Junjie mold parts guides you on how to find the most suitable punches and dies for your works.

What are the must-have qualities for a press brake tool?
To evaluate the quality of a press brake tool, the 3 must-haves – the essential parameters of a good tool – are:

1 – TOUGHNESS/DURABILITY.
In order to be considered tough and durable, the tools have to:

withstand crushing forces: they have to bear the heavy loads applied in sheet metal bending (punches and dies)
withstand fatigue: they have to resist the repetitive cycles of metal processing (mainly for punches)
have good surface hardness: resist the abrasive wear caused by sheet metal sliding (mainly for dies).
What do these properties depend on? Mainly on three factors:

the type of steel used to fabricate the tool (strength resistance)
heat treatments (strength resistance but especially abrasive wear protection)
the profile of the tool, both in terms of shape and of dimensions.

2 – ACCURACY.
Press brake tools must be fabricated with extremely accurate dimensional tolerances, so as to ensure the highest degree of precision during metal processing. This helps prevent bending mistakes, ensure that the tools are properly aligned during setup, and make sure they are interchangeable, in case single segments of tools need to be partially replaced.

3 – FUNCTIONALITY.
When designing and manufacturing press brake tools, three fundamental aspects must be taken care of: shape, dimensions and properties. Why? Because the tools must be as functional as possible: they have to comply and combine with the features of the press brake they will be installed on, to meet the requirements of most users.

What are the necessary characteristics of precision mold accessories?

 

• 

What are the necessary characteristics of precision mold accessories?

Die accessories refers to the general term for metal accessories used in stamping molds, plastic molds or FA automation equipment that are proprietary to the die industry. Mold accessories include: punching needle, block punch and dies, guide post, guide sleeve, thimble, cylinder, steel ball sleeve, no oil guide sleeve, no oil slide, guide post assembly, etc.

1. Wear resistance
When the billet is plastic denaturated in the mold cavity, it flows and slides along the surface of the mold cavity, causing severe friction between the surface of the mold cavity and the billet, resulting in the failure of the mold due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting wear resistance. Under normal circumstances, the higher the hardness of the mold parts, the smaller the wear amount, and the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
2. Strength and toughness
Most of the working conditions of the mold are very bad, and some often bear a large impact load, resulting in brittle fracture. In order to prevent the sudden brittle break of the mold parts during work, the mold should have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and microstructure of the material.
3. fatigue fracture performance
In the process of mold operation, the long-term action of cyclic stress often leads to fatigue fracture. Its forms include low energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the die mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
4.high temperature performance
When the working temperature of the mold is high, the hardness and strength will decrease, resulting in early wear or plastic deformation of the mold and failure. Therefore, the mold material should have a high tempering stability to ensure that the mold has a high hardness and strength at the working temperature.
5.cold and heat fatigue resistance
Some molds are in the state of repeated heating and cooling during the working process, so that the surface of the cavity is strained and the pressure changes the stress, causing the surface cracking and spalling, increasing the friction force, hindering the plastic deformation, reducing the dimensional accuracy, resulting in the failure of the mold. Hot and cold fatigue is one of the main failure forms of hot working die, and this kind of die should have high resistance to cold and heat fatigue.
6. Corrosion resistance
Some molds, such as plastic molds, when working, due to the presence of chlorine, fluorine and other elements in the plastic, after heat decomposition and precipitation of HCI, HF and other strong corrosive gases, erosion of the surface of the mold cavity, increase its surface roughness, exacerbate wear failure.
