Automatic production of CAD-based reinforcement meshes

The economy demands concepts that focus on maximum efficiency and maximum reliability. mbk, manufacturer of wire cage welding machines for the construction, concrete and precast industry, is continuously working on making modern manufacturing processes possible with innovative machine concepts. mbk is headquartered in Kisslegg, Germany and has long been known in the industry as a global player and partner for system solutions. Over 1,000 welding machines and 1,200 machines sold in total inspire customers in over 60 countries around the world.

The automatic production of CAD-based reinforcement meshes for the manufacture of precast concrete elements with cut-outs for window and door openings is gaining increasingly in importance. To meet these needs, mbk developed the flexible MSM-M mesh welding plant, which welds reinforcing steel meshes off the coil according to individual specifications. Depending on the requirements, the producible mesh width lies within a range of 400 to 4,000 mm, while the mesh lengths range from 1,000 to 14,000 mm. Larger dimensions are possible on request.

The DRA-M multiple rotor straightening and cutting machine automatically supplies the longitudinal and transverse wires for the flexible mesh production off the coil. The wire diameter ranges from 6 mm to 16 mm, optionally from 5 mm to 20 mm. The pitch for the longitudinal wire is 25 mm; the spacing of the longitudinal wires depends on their diameter. The minimum spacing of the transverse wire is fixed at 50 mm; infinite adjustability is also possible as an option.

The average production output is around 160 m2/h metres/hour; however, this depends on the mesh occupancy and the cut-outs. Here too, a higher output is possible on request.

The compact plant requires very little space and the modularity of the system allows for individual, customer-specific solutions. Subsequent system extensions are also easily possible.

The stable construction and the low maintenance requirement guarantee convincing everyday suitability. The connection to the Unitechnik CAD-CAM interface enables the uncomplicated and free exchange of information inside the precast plant. LAN and WLAN connections satisfy the prerequisites for fast and simple troubleshooting as well as the use of updates for production planning.

A large range of accessories for automation is offered for the MSM-M mesh welding plant, making useful extensions possible:

Solutions

  • for mesh handling
  • for mesh deposition for “stand-alone” plants or in downstream circulation plants
  • for further processing in downstream bending stations for the bending up and cropping of the bars to produce various bent shapes for precast slabs with in-situ topping, solid sandwich walls and double walls.

Mesh buffers for the buffering and supplementing of the finished welded meshes can be adapted to suit the specific customer.

mbk Maschinenbau GmbH develops, designs and manufactures in accordance with a thorough analysis and the customer’s needs as well as in-depth consultation with a highly competent development and technology team on an area of around 10,000 m2 at the Kisslegg site. With all developments the focus is placed on finding the solution to individual customer requirements and on the aspect of economic efficiency.

Since 1961, mbk Maschinenbau GmbH has been able to convince its worldwide customers with technical innovations, future-oriented systems and sustainability. Furthermore, mbk offers a professional and mature after-sales service. Thus, mbk guarantees its customers that everything will run smoothly even after commissioning.
