摘要： Problems resulting from weld failures in the assembly of vehicle seats are reduced by providing a mechanical lock between a seat frame component and a recliner component. Because impact or impulse forced movement of the components is limited by the mechanical lock, reliance on welding alone is eliminated and the amount of welding done during assembly is reduced. The combined seat and recliner components can accordingly be assembled at reduced cost, and increased torsion moment in the side member resulting from the mechanical lock can further result in the mass (weight) of the system being reduced.
摘要翻译：通过在座椅框架部件和斜倚器部件之间提供机械锁定来减少车辆座椅组装中的焊接故障导致的问题。由于组件的冲击或冲击强制移动受到机械锁定的限制，消除了对焊接的依赖，并且组装期间完成的焊接量减少。组合的座椅和躺椅部件因此可以以较低的成本组装，并且由机械锁定导致的侧部件中增加的扭转力矩可进一步导致系统的质量（重量）减小。

摘要： A hydrostatic or pneumatic drive for driving a mass to be accelerated and decelerated, such as in a die casting or injection moulding machine, has a controllable valve arrangement which is operable to vary the fluid flow rate therethrough. The fluid flow rate is controlled by a reference value control generator operable to produce a ramp having superimposed thereon further control pulses. Such control pulses are a positive control pulse at the beginning of the rising slope and at the end of the falling slope of the ramp and a negative control pulse at the end of the rising slope and at the beginning of the falling slope of the ramp. Each control pulse has a volume which corresponds to a so-called compression volume factor which reflects the compressibility of the fluid used in the drive and also of the elasticity of ducts which expand by fluid pressure.

摘要： A pressing-in unit for a hot-chamber pressure diecasting machine permits an electro-mechanical drive for the casting plunger. In order to absorb the moments of inertia of the drive which occur during the switch-over of the casting plunger drive from the mold filling phase to the after-pressure phase, a spring element in the form of a plastic component or a liquid spring is inserted between the casting plunger and the pusher rod moved by the electric drive, which spring element is compressed by the additional path which the pusher rod still covers after the braking of the motor. The extent of the compression is selected such that the resulting axial force which is exercised by the plastic component or by the liquid spring is sufficient for causing the desired after-pressure in the molten metal.

摘要： A method is disclosed for controlling an injection molding machine of the type having an injection screw drivable for axial movement within an extrusion cylinder by a drive-controlled servo motor through a mechanical transmission, to provide a filling phase, a dwell phase, and a plasticization phase, the servo motor having a velocity command signal input connection, and the molding machine having sensors for screw position and injection pressure. The method includes the steps of presetting desired values for at least one of the injection pressure and the screw position; sensing the respective one of the corresponding actual injection pressure and actual screw position; and transmitting non-zero velocity command signals to the drive-controlled servo motor during at least the plasticization phase, and preferably also the filling and dwell phases, to move the injection screw within the cylinder. The velocity command signals are calculated as a function of a deviation of the respective one of the actual injection pressure and the actual screw position from the respective preset desired value, preferably using a linear functional relation during small deviation values, and a non-linear functional relation for large deviation values, to improve stability.

For this purpose it is proposed to use preferably an electrically modulated pressure control valve for the pressure regulating device in the pressure drive system. Even with extremely short acceleration periods resonance oscillations are avoided, which until now prohibited the reduction of the acceleration period.

摘要： So that the injection nozzle (1) in an electrically driven injection molding machine may be driven free of shock into engagement with the mold (10), a spring has been interposed until the present time. The invention now proposes to delete this spring. The injection nozzle (1) is clamped between the stationary mold (10) and the injection unit (4) by two tie bolts or shafts (9) by the electric motor drive. Initially, the injection nozzle (1) is driven into engagement free of shock, for instance by presetting a brake ramp. Thereafter, the nozzle engagement force is adjusted as a function of the injection force or the pressure of the injection material, as the case may be, by way of a corresponding control device. In this manner, a constant equilibrium of engagement pressure and the opening force in the pressure is established, with selectable initial engagement tension. The energy consumption of the drive motor is reduced. With a special structural arrangement the complexity of the controls is substantially less.
