摘要： The invention provides a welding system capable of freely controlling the dispersion and concentration of arc heat over the groove face with an extreamly narrow gap and a high strength and high quality welded joint structure which is formed by this welding system and which is capable of preventing softening/hardening of the structure, the lowering of the toughness thereof and the generation of a crack. According to the welding system, the melting rate of a welding wire is controlled relative to the welding wire feeding rate by changing the characteristic of an arc current so that the range of behavior and the transfer rate of the arc pole (the arc generating main point at a groove surface) are controlled. Further, the welded joint structure consists of a high strength steel having a superfine grain structure with a carbon equivalent of as low as less than 0.38 and a crystal grain size of less than 7 μm and is welded by a consumable electrode type arc welding method so as to control the arc heat distribution on the groove face of the joint.

摘要： In a control system for controlling a motor-driven injection molding machine that comprises an injection unit driven by a servo-motor and a speed feedback control loop for controlling the servo-motor, an amplifier produces a command signal indicative of a torque command value for the servo motor in accordance with a difference between a sensed speed value obtained by a rotation speed sensor and a speed command value. A pressure sensor senses a pressure of resin within a mold to produce a sensed pressure signal indicative of a sensed pressure. A correction amplifier amplifies the sensed pressure signal to produce an amplified signal as a correction value for a torque command value. An adder adds the torque command value and the correction value to produce an addition result to a motor drive.

摘要： A control device for an injection molding machine includes a pattern generator for generating a set pattern of clamping forces. The pattern generating calculates a travel distance of a movable member in the mold clamping system according to the set clamping force and generates the set pattern having an allowable range of deviation that is defined by an upper limit and a lower limit relative to the calculated travel distance. The mold clamping system continuously decreases the clamping such that it falls within the range defined by the allowable range of deviation after the clamping force reaches the value defined by the upper limit.
