Perforated Plate Design Using CAD Software

February 23rd, 2015

RB Engineering received a call from a client who needed help to create a perforated plate design that would stay absolutely flat. In the past it was usual for the client to order the perforated plate from a supplier but, these were usually made by laser or punched which would cause the metal to warp.  This would cause a problem with a build-up of materials being used in the perforated plate. We decided to make the perforated plate using CAD software.

The perforated plate would be made from 5mm 316 stainless steel.  The advantage of having this profiled and cut on the water jet is that there is no warp age of the metal as it is cut using water. The perforated plate has to be installed perfectly level so the material is always cold.

A qualified designer at RB Engineering created the drawing for the perforated plate design using CAD software.  The drawing when then past to a qualified water jet cutter for profiling and creating the plate. The material was required to be cut to a tolerance of 0.05mm.

Before the work began test cutting was done using scrap material to see if having all of the holes closer together would relieve any stress in the rolling of the stainless steel causing the plate to lift.  This didn’t happen so the material was ordered to begin the work on the perforated plate.

When the work was completed it was scheduled for completion. On completion the client collected the perforated plate and it was fitted by their own staff.  Once installed the customer tested the plate and informed us that it was working to their satisfaction and they were able to put a greater

put through of material.

RB Engineering had solved the problem of the perforated plate design for the customer who was more than happy with the work that the production team had carried out. This type of work will now  be standard on all screen deck machines.

Steel Fabrication and Maintenance Work

Steel Fabrication and Maintenance Work

RB Engineering are experienced in all types of Steel Fabrication and Maintenance Work.  Projects such as Roll Cages, Stainless Steel Storage Tanks, Mezzanine Floors, Stainless Steel buildings and staircases, are just some of the projects that the company has worked on.

When a client contacted RB Engineering for help with rusted trunking the work was carried out to a high standard and the client had more than one problem solved.

The hot air trunking from the furnace to a crushing machine had rusted due to condensation that was caused by constant hot and cold temperatures through the trunking.  It was obvious that the trunking would need to be replaced with a material that could cope with the constant change in temperature.  The materials used were 6mm thick mild steel to handle the heat and chromium content to help alleviate the condensation and prevent corrosion within the pipes.

Drawings were taken onsite and then a CAD model was made and put into our duct forming software which unfolds the drawing into a flat pattern that the water jet can follow to profile the necessary parts.   MAG welding was used on this project to produce the required product for the client.  All of the drawings for this Steel Fabrication and Maintenance work were filed for future reference.

The installation was completed on the client premises at an arranged date, and although the work had taken time to complete because of the complexity of the drawings the client was more than happy with the product.

Roll Cage Manufacture and Design

Roll Cage Manufacture and Design

As a bespoke manufacturer RB Engineering are involved in many different types of projects including roll cage manufacture.   This type of project requires specialist skills in the design, welding and the construction of the roll cage.

When an email arrived at the office with a request for a certified roll cage to be fitted to a 50 series x army dodge pickup, the job was picked up by our experienced engineer.   The work would prove to be relatively straight froward to do as this type of project is common place at RB Engineering. .

The customer requested a simple hoop design to fit behind the cab and 2 back stays were also required.  It was important that no space was restricted from the load bed of the vehicle.

The materials used for the project of roll cage manufacture consisted of 90mm of cold drawn seamless tube which was MIG welded to base plates.  All of the welded joints were done to the standard of EN51614-1-2012.  Cross members were designed to go across the vehicles chassis to allow the roll cage to be bolted on.

Once the vehicle had arrived in the workshop, the chassis cross members and attachment plates were mounted.  A CAD drawing was then produced for the tube bending layout and the programme was put into the tube bender machine.

2 back stays were then cut and the tube was then notched to the correct radius.   Using a MAGS welder the stays were then welded to the hoop and the attachment plates were welded to the bottom of the back stays.

On completing the work the roll cage was duly rubbed down and primed with etch primer then painted with 2 coats of black top coat

A full inspection was carried out on the roll cage before the vehicle was returned to the customer.

This roll cage manufacture project is just one of the many various project services that RB Engineering provide for their customers.

During our work with clients it is often the case that time is of the essence for having work completed in the shortest time possible without compromising quality. Good planning and customer communication play an important part in achieving an agreed timescale.  A prime example of this was when a client called in with a problem they had for unloading bulk materials from a hopper. The hopper was in a bad state, it was very rusty and riddled with holes and it was certainly passed its ‘sell-by date’.

The time scale was very imported as our client was expecting a bulk tanker to arrive and be filled up from the hopper and delivered to their next customer.  We had a six hours to complete the work which included stripping out the chute and fabricating a new one using Stainless Steel. It was imperative that the work was completed as soon as possible.

Before beginning the work we were supplied with a drawing. RB Engineering produced an in house CAD drawing for the top flange for water jet cutting, and then went on to complete a drawing for the whole item.

The materials we used for the work was 6mm Stainless Steel flat sheet which was rolled into shape in house with our hydraulic pyramid rollers.  The mounting flange was profiled on our water jet cutter from 10mm Stainless Steel, it was then welded together using our synergic mag welding machine.   Once the work was finished it was delivered and fitted onsite for the client.   The process from start to finish took five hours to complete.

Throughout the time the work being carried out, communication between our client and ourselves was frequent. This helped to ensure that the client had a good insight as to how the work was progressing.

With hard work and efficiency the job was completed to a high standard and well within the essential time frame and our client was able to make the delivery to their customer in time.
