Trinity Body Company Creates "Mold Expert" Escort Host Products

Sanyue Group President Tang Xiuguo once said: "Concrete machinery, mining machinery, lifting machinery and other products go hand in hand, relying on the Sany has a unique full-industrial chain model." As part of the industry chain, Sany body company not only Production of cabs and other important components for each of the Group's flagship products, and the establishment of a complete set of supporting service systems from mold design, sheet metal stamping, electrophoretic coating to bins, and finished production of cover parts for the production of host products. convoy. Starting from this issue, this newspaper will launch a series of reports to tell you about the body company that is called the “behind the scenes” of corporate development.

After many years of exploration and practice, the body company has established a complete set of complete service systems ranging from mold design, sheet metal stamping, electrophoretic coating to bins, and finished production of cover parts in the group. Its advantages have effectively protected the competitive advantages of the Group's major host products.

Comprehensive mold professional team provides protection for host products
In mid-June 2012, the body company received a call from Sany Heavy Machinery: “There are two sets of molds that have quality problems in the stamping production process, which has greatly affected the production schedule and the situation is more urgent. The body company is requested to provide technical support. After laying down the phone, the body company immediately assigned technical personnel to the scene, and these technicians solved problems quickly with a solid professional foundation and ensured production.

"There are many examples of this, there are those who need to help repair molds, and there are technical advices, but more are proposed for each host company to design, make molds, and even provide cover products." Body Company Process Equipment Research Institute Forming Institute responsible person Said.

In fact, the bodybuilder image of this mold expert has long been deeply rooted in the group. Behind the aura is a professional and experienced mold R&D team. They rely on the industry-leading mold CAE/CAD/CAM technology platform and a series of The advanced mold manufacturing and defect processing equipment strongly protect the production of the host companies within the group.

At present, this outstanding team has developed over 500 sets of large, medium and small-sized molds for various business units of the Group. Thin-plate series products such as cabinets and coverings cover most of the Group's main products.

Thick plate forming strength takes the lead in the industry

The use of die stamping as an advanced manufacturing method has the characteristics of high accuracy, high consistency, high efficiency, and low consumption. These features are unmatched by other manufacturing methods. Therefore, the mold is also called "benefit amplifier."

In order to maximize the benefits of this "amplifier". The body company has strengthened R&D, and has made significant progress in the field of thick board molding where the recognized difficulty coefficient is large and development is weak.

Taking the rear leg bending plate of a pump truck as an example, the multi-knife bending process was used in the past, and the molding process needs to be repeatedly calibrated, which not only consumes a large amount of labor, but also has obvious bending indentations on the appearance of parts, and the consistency of parts is also difficult to guarantee. The body company has developed a pump leg molding mold through deep research on thick plate forming and rebound control technology, which fundamentally solves this problem, and the level of refinement and processing efficiency of the product has also been greater. Promote.

In fact, in order to meet the diverse plate-forming needs of the Group's internal customers, the body company has made a targeted increase in the development of new molds. “The stirring equipment company's mixing tank was originally formed with coils, with an error of more than 20mm. For this reason, the body company specifically designed two sets of powder cone molds. After commissioning, the error can be controlled within 3MM.” Ding Jianhua, Director, Forming Institute Said.

The molds reduce the cost and sharpen the weapon in the group.

At present, the construction machinery industry has experienced a sharp slowdown, and “opening up sources and reducing expenditure and improving internal strength” has increasingly become the key word for major companies. For steel, the main part of the cost of construction machinery products, a series of residual stamping and blanking molds developed by body companies have come in handy. This series of molds has greatly improved the utilization of steel and saved the company cost.

Taking the excavation cab as an example, there is nearly 20KG of spare steel material on the right side of a cab, and if it is treated as scrap, the income will be less than 30 yuan, and the remaining material will be processed into the digging cab by using the die. The two parts above the mixer toolbox have been magnified several times in economic value. This excavator cab, if calculated in accordance with the annual output of 8,000 units, can accumulate cost savings of more than 1,000 million a year. The body company's improvement activities also won the Group's second-quarter QCD improvement second prize in 2011.

Since 2011, the mold development team of the body company has developed more than 110 sets of stamping dies for small parts such as light cutting, punching, shearing, and bending for mass production, significantly reducing the manufacturing cost of small parts, and also reducing the manufacturing costs. The load rate of the heavy equipment such as light cutting machines.

For the future, this mold star team is full of confidence. “We will continue to consolidate our leading edge in molds, continue to expand our service scope, and are determined to be the strong backing for achieving the Group’s 100 billion yuan target,” said a person in charge of the body company.
