DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a mobile scrap cutter and to a method for assembling and disassembling the same, so that the scrap cutter can be moved cost-effectively to and used at the respective operating site to cut scrap.
2. Description of the Prior Art
Mobile scrap cutters known in the art are typically divided into two groups: In the first group, a functional unit is permanently mounted, for example, on an automobile, e.g. a truck, and is ready for use and can be operated at any time; in the second group, a folded-up unit is placed on a flatbed transport unit and has to be reassembled at the operating site before the unit fully functional. Conventional scrap cutters in the second group are typically folded up by rotating the cutter stand with respect to the press bed or vice versa.
It is difficult to secure the components of this type of scrap cutter in place during transport and during the operation.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a mobile scrap cutter which overcomes the above problem and can be easily transported. The scrap cutter of the invention has at least two preassembled transport units which include the following components: a base frame with spring elements and support members, a cutter stand with a cutter bar carriage, a press bed with a slider cylinder and a slider, a hydraulic drive unit with accessories, such as hydraulic lines and an oil cooler, and a control box. It is another object of the invention to provide a method for assembling and disassembling the scrap cutter within a short time and to employ mass-produced components adapted for use in conventional permanently installed scrap cutters.
The object is solved in that one of the transport units forms the base frame and holds the components during transport as well as during the operation. During transport, the cutter stand is laid down by pivoting the cutter stand about a pivot point. The other transport unit is formed by the press bed which has auxiliary support members for transport. Additional embodiments of the invention include having the slider cylinder together with the slider plate laid down on the first transport unit. The hydraulic drive unit, the oil cooler, the hydraulic lines and the control box may be permanently mounted on the base frame. The cutter stand may further comprise the spring element; a swivel bearing; and a support bolt which is used during transport. The spring elements may be secured during transport by clamping means. The base frame may comprise support members, permanently mounted to the base frame, for supporting the press bed. The support members may be split to be spaced apart and arranged on the press bed. The support members may be provided with insertion guides for mounting the press bed. The spring elements may be fixed in place during transport through the support members. The cutter stand may form a separate transport unit. The press bed may be completely preassembled without a lateral pressure cylinder. Support cables may be included which are matched to the load distribution.
The mobile scrap cutter can be assembled within a short time by using the assembly method for assembling a mobile scrap cutter comprising the steps of: lifting a base frame including a superstructure from transport means; placing the base frame on a prepared ground location; raising a cutter stand by pivoting the cutter stand about a pivot point via a swivel bearing; placing the cutter stand on spring elements; pulling out a support bolt; releasing clamping means of the spring elements; lifting and removing a slider cylinder and a slider plate from the base frame; lifting a press bed from transport means; placing the press bed onto support members which are split and spaced apart; connecting the split support members to each other; releasing the clamping means of the spring elements of the press bed which were secured for transport; connecting the press bed to the cutter stand; installing the cutter and a stamping rail; liftin
