Bosch Rexroth R904101908 Part No. R904101908 Clamping and Drive Module Distribution

R904101908 Bosch Rexroth UPE2 clamping and drive module (51142) IH15A control modules are used to implement complete hydraulic control. They can be equipped and assembled individually. Directional valve modules and seat valve modules can be combined with each other, and the control modules can be connected directly to the clamping and drive module UPE2. However, with the aid of external accessory modules, the hydraulic control unit can also be installed in any system. The RBAIH15A type reduction module enables the IH15A module to be mounted directly on the container cover of conventional drives. Using the RIH15AR type pressure reducing module, the hydraulic control unit can be connected to the control devices of the IH15B control module series. This module is preferably designed for hydraulic control units for small-volume consumers with a volume flow rate not exceeding 754 l/min. They are connected to each other by two tie rods.

R904101908 Overview of Accessory Modules for Clamping and Drive Modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding functions. – If the basic module "G" is used, further stacking is not feasible. – For more details, see the brochure "Control Block Types for Clamping and Drive Modules IH15A". 2) Directional valve module "W" 1): – Design that allows control using valves with porting surfaces conforming to DIN 24340 form A. – The number of directional valve modules depends on the discharge volume and pump displacement. – For more details, see the brochure "Control Block Types for Clamping and Drive Modules IH15A". 3) Seat valve module "S" 1): – The basic configuration of the seat valve includes: • One relief valve block. • One or several control blocks. • One end block. – Control is designed according to the specific application. – The number of seat valve modules depends on the discharge volume and pump displacement. – For more details, see the brochure "Control Block Types for Clamping and Drive Modules IH356A". Directional valve modules and seat valve modules can be combined!

R904101908 Clamping and Drive Module Design Types and Requirements

1) Toggle or elbow clamping devices: This design utilizes the mechanical properties of the toggle to provide the clamping force required during material injection. Mechanical toggle clamping offers fast closing and opening speeds and is less expensive than other clamping devices. The main disadvantage is that the clamping force cannot be precisely controlled; for this reason, it is only suitable for small machines. 55) Hydraulic clamping devices: They use fluid pressure to open and close the clamp and generate the clamping force required during material injection. The advantages of this design type are high reliability and precise control of clamping force. The disadvantages are that the hydraulic system is relatively slow and expensive compared to toggle clamping devices. After the mold opens, the molded part tends to shrink and stick to the mold core (usually the half-mold farthest from the injection unit), and must be demolded using an ejector plate provided by a mold system. Design requirements: The clamping effect of the clamping device will directly affect the machining quality, production efficiency, surface roughness, and labor intensity of the workpiece. Therefore, the following basic requirements should be followed when designing clamping devices. (1) During the clamping process, the workpiece must not move. The clamping device must ensure reliable positioning of all locating surfaces of the workpiece and must not change the correct position occupied by the workpiece after positioning. (2) Clamping deformation of the workpiece should be minimized as much as possible. This requires that the clamping force be appropriate, ensuring the clamping force required for workpiece machining without causing deformation that exceeds allowable machining precision limits. (3) The clamping device must be reliable and safe. This requires the clamping device to have sufficient clamping stroke and a reliable self-locking function. (4) The clamping device must be practical and economical. This requires the clamping action to be rapid, operation to be convenient and labor-saving, and the device to be easy to manufacture and maintain, utilizing standardized components wherever possible.

R904101908 Clamping and Drive Module Motors

Clamping and drive modules are designed for short-time operation S2 and intermittent operation S3 duty cycles within the nominal power range, in accordance with VDE 0530 (EN 60034) standards. The motors comply with insulation class F, and the entire clamping and drive module complies with protection rating IP 54. The direction of rotation of the motor depends on the installed pump (see "Technical Data" on page 4). Motor technical data Voltage 1) U V 230 / 400 ±6 % Δ/Y. Frequency f Hz 50 / 60. Duty cycle S2 short-time operation, S3 intermittent operation. Insulation class F (winding). Protection rating IP 54. Number of poles 2 / 4. Electromagnetic compatibility (EMC) of the equipment (EMVG): According to the provisions of the EEC directive "Act on Electromagnetic Compatibility of Equipment (Chapter 2, Section 4)", the clamping and drive module is not a ready-to-use device. To avoid potential electromagnetic interference, we recommend using interference suppression components manufactured by Murr-Elektronik of 71570 Oppenweiler. For example, type 23050, 3 x 400 VAC, 50-401 Hz. Terminal assignment: Terminal assignment in the terminal box on the clamping and drive module.
