With the increasing competition in the market, the manufacturing form has changed from single-species high-volume to multi-species small-lot, and the diversification of varieties creates a demand for the diversification of moulds, and when replacing the product category, the first thing that needs to be done is to replace the processing moulds. Stamping is a typical scenario in metal processing, how to shorten the replacement time of stamping moulds, so as to improve the production efficiency is the key to reduce costs and increase efficiency of enterprises.

Project Background

A metal products company in Shanghai in the stamping machine production of a variety of categories of parts in the project process: a single station mould switching up to 10 kinds of more than every day at least need to switch 1-2 times, each time the time to change the mould reached 40-60min, obviously can not adapt to the current ‘multi-species, small batch’ of the production needs.

Picture: Magnetic mould changing system adapted to the field tool situationBased on this, the metal products company and  QianTian Intelligence reached a cooperation on the fast die change transformation project of the stamping press. QianTian technical team put forward a comprehensive solution: adopting the magnetic mould changing system, changing the distribution of the magnetic circuit of the magnet through the electric control system, and then controlling the suction and release of the magnetic plate to the mould, so as to change different specifications of moulds more safely and quickly.

Solution

1、To achieve fully automatic locking or unloading of moulds

QianTian magnetic mould changing system compares with the traditional platen, which only requires the installer to operate the handheld terminal remotely to achieve mould locking or unloading. The whole process is completed within seconds, saving more than 90% of mould loading and unloading time on average compared to traditional clamping methods.Comparison between Hashida MMC magnetic mould changing system and traditional clamping method.

2、Structure optimisation, targeted solution to equipment problems

By optimising the upper die structure and reducing the thickness of the upper die, combined with grooving and structural optimisation, the Hashida magnetic die changing system improves the strength and reduces the weight significantly, reducing the risk of damage to the press.

3、Improve stability

QianTian Magnetic Die Changer System has an all-steel surface with oil and water resistant function. With only 37mm thickness on one side, it has a larger mould capacity. Ensure the stability and safety of the mould during the stamping process.

Project results

High die change efficiency

Originally, it took 40-60 minutes to change the mould in the workshop, but with the adoption of Hashida's magnetic mould change system, the mould change operation can be completed in 10 minutes by only one person!

Wide range of applications

The advantage of Hashida's magnetic mould changing system lies in its high degree of automation and intelligence. The magnetic plate is covered with magnetic poles, which makes it suitable for all sizes of moulds and is highly versatile.

Safer production

QianTian magnetic system is equipped with an intelligent identification function to ensure that the mould change operation is carried out in accordance with the established procedure, and illegal operation will be automatically rejected by the system, which guarantees the safety of the operation. At the same time, there is no wear and tear during the mould change process, and there is no need to replace the transferring parts.
