How to choose the automatic stamping production line

The automatic stamping production line mainly includes: progressive die stamping, multi-station stamping and tandem stamping. Due to their respective characteristics, they are used to produce different automotive sheet metal parts. With their unique advantages, they play a huge role in automotive automation and efficient production systems.

Selection factors for stamping automated production lines

(1)Product material: including material type, form, hardness, etc., to measure the choice of coil or sheet forming.

(2)Material thickness: Synergistic materials are considered together to select the tonnage of the press machine and the matching form of the feeding mechanism.

(3)Monthly supply and demand: assess production capacity, determine production tempo, and weigh the selection of automatic line types.

(4)The volume and shape of the stamping product: Through the modeling complexity and product quality requirements, the mold design method and the corresponding stamping automation production method are comprehensively considered.

Progressive die stamping production line

The progressive die stamping automatic production line is a production line using progressive die to make, which is generally composed of feeder, punching machine, progressive die, and automatic discharge line. The whole automatic process is with uncoiling, flattening, oiling, stamping and off-line collecting finished products.

Features: The automatic production line of progressive die stamping has a high production rhythm, which can generally reach more than 30 times per minute.

a. High production efficiency. The progressive die is a multi-tasking die that can include various processes such as punching, bending, and deep drawing in a pair of molds, and has high productivity.

b. Easy to automate, reduce labor costs and increase production efficiency

c. Can be produced by high speed punching

d. Operational safety.

e. Save production area.

f. Material utilization is not high.

Multi-station stamping automation production line

(1)Overview: A large-tonnage press table is equipped with multiple (usually 4~5 pairs of molds) independent working position mold production lines, using the unwinding feeder to feed, using the automatic feeding rod for process parts transfer, using automatic transmission Belt collection offline products

Features.

a. The rail material can be a coil material or a sheet, which has great flexibility and is beneficial to improving material utilization.

b. Use automatic rod feeding to achieve high production efficiency.

c. The sensor can be added to detect the position and state of the material and the parts in production, the safety is high.

d. There is a high requirement for the feeding height and the punching direction of each station. In order to ensure the stability of the feeding, it is generally necessary to ensure the consistency of the process steps in each process.

Tandem stamping automated production line

(1)Overview: It is arranged in series by a plurality of presses and connected in series to form an automated production line. A pair of molds (is a process of the production process) is placed on each press table, and the loading, transferring, and packing of the work pieces are completed by an automatic robot arm or robot.

Features.

a. Wide application range, can be applied to the production of various stamping parts, and has great flexibility.

b. Low production efficiency

c. Facilitate die maintenance and debugging. Because each die belongs to each press, clamping and working parameters are independent, the maintenance and debugging of each die process can be carried out independently without affecting each other.

d. Occupy a large area of production plant

Selection and application of stamping automation production line

Progressive Die Stamping Automated Production Line: For the process characteristics of the various processes distributed on a single strip and the higher process punches that can be achieved, it can be applied to the production of small parts on the body and can meet a high supply.

Multi-station stamping automation production line: It can be applied to the rapid production of medium-sized parts, the beam parts that are not easy to be deformed, the symmetrical parts with complex left and right common-mode shapes, and the products that can be clamped by the clips on the automatic rod can be applied. The production of this automatic line.

Tandem stamping automation production line: Because each process is independently distributed in each press, the line has the highest flexibility and is suitable for large-scale coverings with complicated production process, which is conducive to the debugging and independent production of individual processes, and is convenient for quality control of products.

With its own characteristics, the stamping automation production line has been applied to major automobile factories, providing a strong guarantee for the development of the automotive industry and the rapid growth of automobile production. The analysis and understanding of the stamping automation production line facilitates the selection of stamping parts production methods, making full use of the advantages of their respective automatic lines to serve the automotive field.
