摘要： A thermoforming machine utilizes two clamping frames to advance cut sheets through heating and forming stations, with the clamping frames returned via an overhead path above the oven in the heating station. Pneumatic cylinders arranged about the inner perimeter of the frames are operated to grip the sheet and release the sheets, which are pressurized and released via fluid connections established when the frames are lifted from a transfer bar structure at the loading and forming stations. The clamping frames have pivoted end sections which are engaged by extendible gear posts at the forming station to bend the clamped sheet into greater conformity with the tooling shape prior to forming.
摘要翻译：热成型机使用两个夹紧框架来通过加热和成型站推进切割片材，夹紧框架通过加热站中烤箱上方的架空路径返回。围绕框架的内周布置的气缸被操作以夹紧片材并释放片材，片材通过当框架在装载和成形站处从转移杆结构提升时建立的流体连接被加压和释放。夹紧框架具有枢转的端部部分，其在成形工位处由可延伸的齿轮柱接合，以在成形之前使夹紧的片材与工具形状更加一致。

摘要： A thermoforming press in which the shut height of upper and lower platens is adjustable by a keyed connection between a press frame top assembly and each of four posts of the frame established by pieces which are movable and which also act as cams to raise or lower the frame top assembly, moving the upper platen therewith to vary the shut height. The movable pieces are moved in unison by a drive motor to insure uniform movement of the frame top assembly. The platens are driven by rotary crank plates, which are in turn driven by rotary output shafts of right angle drives. Pairs of rollers engage the perimeter of each crank plate on one side to resist bending loads on each shaft.

摘要： A servo motor in die tapping unit provides built in shock protection for the motor by fixing a shock plate to the servo motor and floatingly mounting the shock plate to a base structure attachable to a stripper plate in a press. Sets of opposing springs allow movement of the shock plate relative the base plate to relieve shock loads when the press is operated, the shock plate guided on dowel pins fixed to the base structure. The shock plate, and tapping unit and base structure form a self contained assembly for mounting together in the press.

摘要： A punch press ram drive is described in which a reversible electrical servo motor is coupled to a crankshaft having an eccentric journal driving a pitman arm connected to the ram. The electrical servo motor is operated by program controls so as to either cause rotation or oscillation of the crankshaft to drive the ram through various programmed stroking modes, in which punch position, velocity, acceleration, varying over the course of a stroke may be programmed.

摘要： A system is disclosed for registering a sheet in punch press or other apparatus having a control system carrying out a programmed position of the sheet during punching operations, in which a movable locator plate is urged into an advanced position along an axis of movement so as to be displaced when the sheet is moved a fixed distance along one axis. A distance transducer generates a continuously varying electrical signal corresponding to the displacement of the locator plate from its advanced position, which signal is transmitted to the control system to modify the part program in accordance with the actual location of the sheet.

摘要： An article of manufacture comprises a flanged demountable pin or bushing element having a generally cylindrical shape and a main section having a main diameter and a circumferential groove. Assembled within the groove is a plurality of partially annular pieces forming a complete inner collar with an inner diameter section and an outer diameter section. The inner diameter of the inner diameter section of the inner collar is matched to the groove diameter; and in some embodiments the outer diameter of the outer diameter section of the inner collar is greater than the main diameter of the main section such that the inner collar protrudes from the groove. An outer ring has an inner diameter section and an outer diameter section and is engaged with the inner collar to form a flange on the element. Also disclosed is a method of manufacturing to order demountable pin or bushing elements.
