Metal stamping die jump crumbs means phenomenon that sheet should in the edge jump to die surface after finish blanking shear in high-speed production die.As one of the usual metal stamping bad phenomenon, The cause of jump crumbs phenomenon produce is various,some cause by bad die design, some cause by bad material, some cause by
Metal stamping die material including steel, carbide, steel bonded carbide, zinc alloy, low melting point alloy, aluminum bronze, high polymer material etc. Most stamping die material use steel-oriented at present, common die working part material mainly included: 1. Carbon tool steelUse for metal stamping die, carbon steel of cutting tool and measuring tool, compared with
Progressive die is the name of the die structure,basically can be interpreted as stamping parts can’t finish production from any one stamping die in one-time stamping by punching, bent or amplify mold,etc.It must use many sets die or many process to finish stamping.Design these parts of multi project or multi die in the same die,use math
There are many kinds of tiny precision metal stampings products in the market for medic, wear device, electronics, automotive, aerospace, home applicants, telecommunication industries and more. With the promoting custom ized stamping components, many precision metal stamping makers can meet individual program requirements and solve problems caused by badly designed existing metal stampings as well.
There are many products on the market stamped by progressive die, from the tiny electronic, electrical products to medium and large parts in car and aircraft. And the shapes of the stamping products are variety. All kinds of die processing engineering are differences..The progressive die design general can be divided into five major projects: Understand
In recent years, as the high technology, high performance processing and miniaturization trend of electronic products development, the connector terminal performance is higher and higher. The progressive die process is facing more and more high technical requirements and challenges. Higher level of mold design. Due to the different shapes of terminals, how to make reasonable
The high-efficiency and energy-saving of the precision punching machine will consume energy when the punching machine is activated. 1. Traditional precision punching machine When the work is standing by, the motor will be still rotating unceasingly to keep pressing energy. 2. Precision press machine Energy don’t need to be stored in advance, when the work
A. From system point of view, as the aspects of stamping, die manufacturing, the structure and produce design project of in-die riveting should attach great importance to the role of practical experience and a practical solution to establish feasible die design. B. In-die riveting structure is complex, difficult to design, and cost highly, design cycle
The proper use and maintenance of progressive die is an important measure to prolong die life. The use of progressive die should pay attention to the following aspects: Ensure the balance and lifting of the upper die when the metal die is installed, prevent the overtilt of the upper mould leading to the rupture of
