Description

[0001] A MECHANISM FOR ISOLATING THE SYSTEM LOAD FROM MOVING ELEMENTS IN LINEAR MOTION SYSTEMS

[0002] Technical Field

[0003] The invention relates to a mechanism that isolates the system load from the carrier elements during pressing and transfers it to the stationary main structure in linear motion variable mold pressing systems.

[0004] The mechanism of the present invention makes the pressing capacity of the system independent of the loading limits of the moving carrier elements used in these systems, enabling the development of pressing applications irrespective of the transportation limits of the moving carrier elements.

[0005] State of the Art

[0006] Press machines are widely used in forging, riveting, molding, cutting, punching, deep drawing, metal forming, as well as lifting and compressing large parts. Presses can be hydraulic or mechanical. In the known state of the art, the pressing capacity of the moving pressing systems is limited to the carrying capacity of the moving carrier elements in the system. The carrying capacity of the carrier elements is directly proportional to the dimensions and cost of the element, and the need for very large working areas in many applications causes physical and cost problems due to high costs.

[0007] For these reasons, there is a need for a mechanism to eliminate these disadvantages.

[0008] Brief Description of the Invention

[0009] One purpose of the invention is to enable pressing at values that are not normally possible, especially on moving systems in press systems, punch machines and crushing and forming machines.

[0010] Another purpose of the invention is to make the press capacity independent of the loading limits of the movable carrier elements used in press systems. Thus, the goal is to reduce the cost of manufacturing with lighter elements and physically smaller designs.

[0011] Another purpose of the invention is to provide an advantage in terms of reducing maintenance and repair costs, thereby lowering operating costs overall, by reducing the energy consumption and prolonging the life of the linear motion elements of the press machine thanks to the smaller size of the equipment.

[0024] Detailed Description of the Invention

[0025] Exemplary embodiments are described in more detail by referring to the accompanying description below. However, embodiments may be provided in different forms and should not be construed as being limited to the embodiments set forth herein. Instead, these exemplary embodiments are provided to complete the disclosure and to fully convey its scope to those skilled in the art.

[0026] The terminology used in this description is intended only to describe a specific exemplary embodiment and is not intended to be restrictive. As used herein, the forms “a / an”, “at least” and “preferably” are intended to include plural forms as well, unless the context expressly states otherwise.

[0027] The invention comprises at least one support plate (3) positioned on a main body (1), connected to at least one carrier plate (7) whose weight is balanced by springs (4) on at least one bearing carrier system (5). At least one mold (6) is located on the carrier plate (7).

[0028] Another application of the invention is the positioning of the support plates (3) that ensures that the position of the piston (2) remains stable by the springs (4) that press in the direction of the piston (2) positioned on the mold (6) to be seated on the bearing carrier system (5) with moving elements, and by the reverse force on the body of the piston (2) during pressing. The mentioned application is as shown in the representative view in Fig. 2.

[0029] In the invention, at least one spring (4) allows the carrier plate (7) to be stretched only perpendicular to the movement using the bearing carrier system (5) that provides the motion. During the linear motion, the springs (4) remove the support plate (3) from the main body (1) and eliminate the friction obstacle for positioning. The invention also comprises at least one punch (8) element that punches a hole in the sheet metal workpiece to be punched according to the desired shape.

[0030] When the positioning takes place, the springs (4) adjusted by the pressure of the piston (2) stretch and place the carrier plate (7) on the main body (1), ensuring that the bearing carrier system (5) remains isolated from the load and transfers the system load to the main body (1). After the pressing process is finished, the mechanism comes back into balance with the springs (4) and is ready for linear motion. In the meantime, the piston (2) rests strongly on the support plates (3) in the direction of moving away from the bearing carrier system (5) with moving elements during pressing, and remains stationary for the duration of the press pressure. The springs (4) herein are the elements that cut off the contact of the press with the bearing carrier system (5) with moving elements, and allow it to contact the support plate (3). In this way, the bearing carrier system (5) is exposed to as much pressure as the springs (4) and maintained. As soon as the pressing process is finished, when the force pushing the press up ends, the springs (4) separate the carrier plate (7) from the main body (1) and place it on the bearing carrier system (5). In this way, the piston (2) is ready to move to the next position.

[0031] Industrial Applicability of the Invention

[0032] The invention relates to a mechanism that isolates the system load from the carrier elements during pressing and transfers it to the stationary main structure, especially in press systems, punch machines and crushing and forming machines, making it applicable to the industry.

[0033] The invention is not limited to the above description, and a person skilled in the art can easily present different applications of the invention. These should be considered within the scope of the protection requested by the claims of the invention.
