How Does Hebei Three-dimensional Welding Platform Meet Industrial Needs?

How does Hebei three-dimensional welding platform meet industrial needs?

In the Hebei industrial manufacturing circle, the flatness error of a certain welding platform can be controlled and limited to no more than 5 microns per square meter. This directly determines and determines what, in other words, it is the bottom line of quality and safety of auto parts and aerospace equipment.

Everything from car parts to spacecraft is inseparable from it

In Botou, Hebei, there is an entity manufacturer with more than 20 years of experience. It holds a three-dimensional welding platform in its hands. This platform has become a key equipment connecting ordinary manufacturing and high-end manufacturing. In the parts production workshop of Baoding Great Wall Motors, technician Master Wang uses the standard hole system and positioning parts on the platform to fix engine brackets, chassis beams and other components in precise positions every day. This system reduces the welding deformation from 2 mm in the past to less than 0.3 mm, which directly improves the welding quality of the entire vehicle.

In an aerospace materials supporting company in Shijiazhuang, there is an engineer named Li Ming, and his team is using the same platform to carry out welding tests on satellite brackets. In view of the strict requirements for heat-affected zones and dimensional accuracy of aerospace components down to the micron level, the high-rigidity cast iron material used in this platform has undergone two aging treatments, so there is almost no deformation during the welding process. The surface of the platform has a grid design, which allows operators to quickly locate complex curved surface structures, thereby increasing the welding pass rate to 99.8%.

Physical manufacturers guarantee accuracy and efficiency

There is such a heavy industry equipment company in Botou, Hebei Province. It has a 10-ton cupola furnace that provides three-dimensional simulation guidance for riveting and welding assembly services , as well as large-scale equipment such as CNC gantry boring and milling machines. Starting from the molten iron smelting process to the precision machining part, it is completely completed by itself. In the casting shop, workers prepare materials according to the HT250 grade standard to ensure that the platform hardness is stable between HB190 and 220. After finishing with CNC machine tools, the working surface of the platform should be manually trimmed by a scraping and grinding technician to provide three-dimensional simulation guidance, riveting and assembly services. How does Hebei's three-dimensional welding platform meet industrial needs? This scraping and grinding technician has more than 10 years of experience, and the final flatness error does not exceed 5 microns per square meter.

The stable supply capability comes from large-scale production. The company's warehouse often has standard platforms of various specifications. Not only that, it can also customize special platforms with T-shaped slots and U-shaped holes for customers. In the machining workshop, a 6-meter-long CNC gantry milling machine for processing a set of combined platforms for wind power equipment is in operation. The entire machining cycle has been shortened by 30% compared to the industry average.

One-stop service to solve procurement pain points

For purchasing personnel in machinery manufacturing companies, the most troublesome thing is that after buying the equipment, they have to find the installation team themselves. This company provides full-process services starting from drawing design, through casting production, and ending with on-site installation and debugging. Last month, it sent eight 6-meter-long three-dimensional welding platforms to an automobile mold factory in Tianjin. The technical team not only completed the installation and leveling of the equipment, but also conducted a total of two days of on-site training for operators.

Another highlight is the non-standard customization capability. In response to the special-shaped structure welding requirements proposed by a military industrial enterprise, the company's design department communicated repeatedly with the customer and finally designed a special platform with bevels and lateral positioning holes. The entire customization process only took 45 days from order placement to delivery, which is nearly half the time faster than the industry standard cycle. The customer specifically mentioned during the acceptance inspection that the positioning holes on the platform were all positioned to include 0.05 mm.

Used by technicians in many industries

In a wind power equipment manufacturing factory in Cangzhou, the assembly team leader named Master Zhang has to assemble the tower connecting flanges on the welding platform every day. The quick locking device on the platform shortens the time for workpiece clamping from half an hour to just 5 minutes, and the repeatable positioning accuracy remains stable and unchanged. He told reporters that this platform has been in continuous use for three years, and its working surface is still as smooth as new.

In a heavy machinery maintenance workshop in Handan, there is a fitter, Master Li, who uses a marking platform to inspect and measure the excavator's boom. The surface of the platform has been precision scraped and ground, and combined with an electronic level, the deformation of the workpiece can be quickly detected. The workshop director did some calculations and found that since the application of this testing equipment, the repair rate has been reduced by 40%, and the annual material cost savings exceeds 200,000 yuan.

Meet the stringent requirements of high-precision manufacturing

In the fields of shipbuilding and aerospace, the requirements for welding platforms are the most stringent. In Tianjin, at a shipbuilding supporting company, workers are using a three-dimensional flexible welding platform to carry out assembly and welding of marine diesel engine bases. Because the structure of the base is complex and the amount of welding is large, the three-dimensional hole system on the platform makes the tooling design extremely flexible. Technicians can quickly adjust the positioning points according to different machine models, and the time for making a single set of tooling is shortened by 70%.

In the laboratory of an aerospace power research institute, there are researchers who use a precision cast iron platform to carry out dimensional inspection of key engine components. The platform is made of HT300 material, which has experienced many natural aging and has an extremely low thermal expansion coefficient when it is in a constant temperature environment. The experimenters used the datum surface on the platform and the laser tracker to control the measurement uncertainty within 0.02 mm, thus providing reliable data support for the development of new models of engines.

Covering everything from school laboratories to factory workshops

In the training center of the School of Mechanical Engineering of Hebei University of Science and Technology, students practiced robot welding programming on a three-dimensional welding platform. The modular design of the platform makes teaching intuitive. Students can quickly construct the workpiece coordinate system on the grid. The teacher in charge of the college said that equipment such as this, which is completely consistent with the actual production of the company, greatly shortens the time for graduates to adapt to the job.

In the field of electronic manufacturing, precision testing platforms are also indispensable. There is a precision instrument company in Langfang. Xiao Wang, a quality inspector in the company, must use an altimeter to test the flatness of the instrument casing on the granite platform every day. The material of natural granite will not rust and provides three-dimensional simulation guidance for riveting and assembly services . The hardness is very high. When used with a constant temperature laboratory, it can meet the testing requirements of 0.005 mm. The person in charge of the company's quality department said that it is precisely with such testing methods that products can be stably supplied to the world's top 500 companies.
