Individual hydraulic distributor on the drive unit

Small and medium-sized bent parts thanks to Xpert 40 and Xpert 80 from Bystronic

Particularly in the production of high-precision bent parts, reliable machines that can be individually adapted to the manufacturing needs are required. "Often the argument of lack of space and fluctuating capacities also plays an important role in the selection of a suitable bending machine" says Raymond Arndt Design Engineer at Bystronic. In addition to laser cutting systems and pressbrakes, the provider of sheet metal processing solutions also offers corresponding automation and software solutions and stands for powerful innovations, on-site expertise, and outstanding service. The performance of the machines is ensured, among other things, by reliable hydraulic components that are individually adapted to the machines. During the development phase of the Xpert 40 + Xpert 80 press brakes, individual adjustments had to be made to the intended drive unit. This was because the intended connection had fewer connectors than were required, which is why individual screw connections were made in the first step with the aid of a T-piece. On the one hand, these bolting chains proved unsuitable due to the limited space available, and on the other hand, this also increased the risk of leakage. "Since our customers rely on the performance of our machines, we therefore approached Dietzel Hydraulik, a competent partner, in order to benefit from their expertise and many years of experience in the field of customized hydraulic solutions," Raymond Arndt continues. Both companies have already maintained a business relationship for many years, and Bystronic not only obtains individual hydraulic distributors from Dietzel, but also fittings and hose lines for applications in the suction area.

 

Optimizations of the drive unit through individual hydraulic distributors

On the drive unit of the Xpert 40 and Xpert 80, only one connection for a measuring point was provided on site. In addition to this, a further connection for a pressure sensor had to be integrated. The screw connection chain originally planned for this by means of a T-piece resulted in further connection problems and made installation more difficult. The increased volume of parts due to the bolting of several parts also led to space problems in the relatively small Xpert 40 pressbrake. The increased effort required for assembly and the risk of leakage were to be further reasons for optimization. Thus, in a joint exchange with engineers from Dietzel Hydraulik and engineers from Bystronic, an individual distributor was developed that was perfectly integrated into the machine room. The distributor, which is much more compact than the bolting chain, now combines two connections - one each for measuring points and the pressure sensor. The general component requirement for the Xpert 40 and Xpert 80 has thus been reduced enormously. For Bystronic this has a positive effect on the assembly time, simplifies it enormously, and reduces the susceptibility to errors. "Since we now receive the distributor in a compact design directly from Dietzel, we have to keep fewer components in stock, another positive aspect that this creates. The biggest and most important effect for us and our customers, however, is the reduced risk of leakage, as there are far fewer leakage points with the distributor developed by Dietzel Hydraulik," says Raymond Arndt. The developed distributor was then initially manufactured as a prototype at Dietzel Hydraulik before it went into customized series production. After completion of all manufacturing steps, Dietzel tests all parts again for tightness before they are delivered to customers such as Bystronic.

Dietzel Hydraulik specializes in developing individual hydraulic solutions for its customers. In doing so, the company's in-house manufacturing competencies enable maximum flexibility and reliability. Dietzel covers a broad portfolio, from machining and further processing such as welding, soldering, and bending to its own hose assembly stations. Quality is always the focus of the various production steps and is ensured by numerous quality controls.
