A variety of basic machine models are available to suit specific applications.
Six basic models, each of modular design, provide the flexibility necessary to cover a wide spectrum of requirements with regard to output, floor space, and material handling arrangements. Manipulator shot blast systems can be combined with air blast stations and are suitable for integration into automatic fettling lines.
These shot blast systems are either fitted with rotating support shafts or with flexible manipulator grippers to pick up the workpieces and transport them through the shot blast machine. The gripper
tools automatically adapt to the shape of a particular workpiece and are able to accommodate one or more parts.
A loading device or an industrial robot places the uncleaned workpieces on support shafts or in the manipulator where they are firmly held. Fully automatic shot blast systems can be equipped with sensors for part identification and workpiece-specific control of the blast parameters (blast time, shot quantity, throwing speed, workpiece movement during blasting, number of activated blast wheels, shot removal time, etc.). The selective placement of the workpieces ensures optimal and continuous exposure to the blast stream, whilst delivering the best shot energy efficiency and minimal wear of machine parts.
Fully automated production systems call for intelligent materials handling solutions to deliver:
Robots and mechanical devices are available to accomplish these tasks. However, the choice of the appropriate equipment must primarily be based on cost/benefit considerations, infrastructure and customer individual preferences.
These devices offer practical and costsaving solutions for machines in factories with restricted floor space. Continuous throughput machines for workpieces weighing more than 250 kg each, or machines loaded on the front side and unloaded from the rear side, are typical applications for such devices. Their ability to handle different workpieces of diverse shapes is an added advantage.
Industrial robots are generally used in combination with machines operating with short cycle times to process workpieces. The robots can be programmed to carry the workpieces reliably along complex pre-defined paths and to move them into the required positions. High precision and motion repeatability, and flexibility when changing from one task to the next, are important advantages of industrial robots. They can also be used for shot evacuation outside the machine. For systems comprising autonomous cells for blast cleaning, deburring, trimming, and grinding of workpieces, robots can serve to link these individual process stages, helping to reduce unproductive downtime and operating cost.
Depending on the particular application, they can be fitted with a manipulator gripper or with rotational support shafts to receive rotating parts, such as crankshafts, etc. In accordance with the workflow, the machines can be loaded and unloaded at the front or, alternatively be loaded at the front and unloaded from the rear with the help of a robot or a loading device. In most cases the machines can process the workpieces in pairs to increase production output. Programmable motion sequences of the manipulators (rotating, swinging, stopping) ascertain precisely targeted shot impingement on even the most critical workpiece surfaces. The high-tech control system ensures that parts are processed according to preset parameters, such as blast time, shot quantity, throwing speed, number of activated blast wheels, shot removal time, etc.
The compact design of the machines offers ample flexibility with regard to layout and production flow to the user. Moreover, the machines can easily be integrated in existing installations.
These systems can run between 20 and 80 operating cycles to process up to 160 parts per hour. The size and load capacity of the grippers or shafts is chosen according to workpiece type.
In DV shot blast systems, loading / unloading and shot blasting are performed simultaneously. The complete shot blasting of complex workpiece interiors occurs in one operating cycle inside the machine.
A robot or loading device loads and unloads the workpieces at the front of the machine. The system offers the possibility of processing parts in pairs. Programmable manipulator gripper motions (rotating, swinging, stopping) allow for targeted treatment of critical surfaces.
The space-saving design of the system facilitates its integration into existing plants. It’s design concept allows users to coordinate the shot blasting machine with existing peripheral equipment andAmong the typical treatment applications of these high capacity systems are components for the automotive industry, including desanding, descaling and shot peening of rotational parts.
DS 4 machines with 4 compartments are designed for the surface treatment of light metal parts and rotational parts. DS 5, -6, and -8 systems are equipped with 5, 6, and 8 compartments, and are used for the treatment of iron components. Loading and unloading are carried out during the operation of the shot blast machines, by robots or mechanical loading and unloading devices. This enables users to minimise downtime and increase production output. It is also possible to treat the workpieces in pairs. These machines have between 4 and 12 blast wheels and 4, 5, 6 or 8 manipulator grippers. Size and load capacity of the grippers will be selected based on individual requirements.
The blast wheel is the heart of the blasting machine, as the choice of blast wheel determines the power output and the economics.
This machine is fitted with U70x500 Universal (indirect drive) shot blast wheels as standard. The Wheels are highly flexible, compact and have rotation in both directions. They provide perfect blast cleaning results and highly convenient servicing features.
The U Blast Wheels are high capacity blast wheels with maximum energy efficiency. Their rugged design means that maintenance is easy, and the special and highly wear resistant cast alloy liners ensure minimum wear and maximum service life of the blast wheel.
