1. Stamping definition

   Stamping is a forming processing method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size. Also known as: Sheet metal stamping processing, defined as "Sheet metal stamping"

2. Basic process classification

   The stamping process can be divided into two categories: material separation and forming according to its deformation properties.

   Separation process: refers to the stamping process in which the blank is broken and separated after the stress in the deformation part reaches the tensile strength under the action of stamping force, thereby obtaining a workpiece of the required shape and size.

   Forming process: refers to the stamping process in which the stress of the deformed part of the blank reaches the yield point but does not reach the tensile strength under the action of stamping force, causing plastic deformation to the blank without fracture separation, thereby obtaining a workpiece of the required shape and size. .

3. Introduction to stamping molds

   Mold refers to a tool that turns a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, die casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

   There are many types of molds, according to the processing objects and processing techniques, which can be divided into: Processing metals molds; Processing non-metal and powder metallurgy molds

   According to the different materials formed, they are divided into: hardware molds, plastic molds, and special molds.

   Hardware molds are divided into: stamping dies (such as blanking dies, bending dies, drawing dies, hole flanging dies, shrinkage cavity dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.), extrusion press dies, extrusion dies, die-casting dies, forging dies, etc.

4. Fudar Alloy’s plate and strip punching capabilities

   ① All are produced using high-precision punching machines, which can meet the punching and molding requirements of raw materials of different specifications and materials;

   ② In-mold riveting with automatic leakage detection device to ensure the stability of product riveting quality;

   ③ In-mold tapping threads saves target processes and improves production efficiency;

   ④ The use of high-speed punching machines improves work efficiency and meets customer order needs;

   ⑤ The punch machine is treated with a sound insulation cover, which reduces the noise in the workshop and creates a comfortable working environment for employees.

5. Analysis of stamping development trends

   ① Traditional stamping equipment adopts a unit-price connecting production method. The lack of flexibility is an obvious flaw of this production method. In addition, the working curve of the press cannot be changed. These conflicts with the development trend of large batches of vehicle models and rapid changes in varieties will become increasingly prominent.

   ② Large-scale multi-station presses integrate machinery, electronics, control and detection technologies to achieve fully automatic, intelligent, safe operation, high productivity, high quality parts and low overall cost, meeting the needs of mass production in the automotive industry. need.

   ③The servo drive press using servo drive technology combines the flexibility of the hydraulic press with the high efficiency of the mechanical press. At the same time, it realizes stepless adjustment of the stamping movement and punching force during the stamping process, making the working curve of the press matches various application machines.
