Abstract: A press working apparatus is provided with a first working unit and a second working unit 14. In the first working unit, a first stage is performed for forming a half-blanked portion 15 with a projecting shape at a region where a through hole P is to be formed in a sheet W. In the second working unit 14, a second stage S2 is performed in which the half-blanked portion 15 is blanked from the sheet W by a second punch 26 and a second die 23. Also in the second stage S2, when a blanked body is blanked from the sheet W, shaving work is performed with respect to a side wall surface Pa on a region of the sheet W where the blanked body has been blanked.

Also, the device comprises a suspension arm (40) connecting the drive gear (24) to the driven gear (30) in the state of the driven gear (30) reciprocatingly swingable around the rotating center of the drive gear (24) and a suspension spring (50) elastically connecting the wheel (14) to the vehicle body (12).

Abstract: Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

Abstract: A multiple-bolt insertion tool in accordance with the present invention simultaneously inserts bolts into at least two bolt holes arrayed in a workpiece and includes a bolt receiving member and a hold-and-release mechanism. The bolt receiving member includes bolt positioning portions which establish a positional relationship among the bolts that are to be inserted that matches the positional relationship of the bolt holes, and a tool positioning portion, which fits (mates with) the workpiece to locate the bolt positioning portions in alignment with corresponding bolt holes in the workpiece. The hold-and-release mechanism holds the bolts in the bolt positioning portions until the tool positioning portion is mated with the workpiece and can release the bolts from the bolt positioning portions.

Abstract: Machining is possible in such a manner that an optional position of a workpiece is positioned just under a tool by rotation of a turn table in a C-axis direction, movement of the turn table in a Y-axis direction, and movement of a spindle in a Z-axis direction, so that a width of a main unit in a X-axis direction can be made shorter in comparison with machining by moving the turn table in the X-axis direction. Besides, the turn table located on a front side of the main unit, an ATC located on the rear side thereof, and a separated control panel located on the rear side of the ATC, independent from the main unit can also make the width of a machining center in the X-axis direction shorter.

Abstract: A bolt tightening device includes bolt tightening mechanisms, a torque input unit, a toothed belt and torque transmission units. The torque transmission units are provided with toothed pulleys and are integrated with the bolt tightening mechanisms. A toothed pulley is fixed to the torque input unit, and drivably connected to all the toothed pulleys of the plural torque input units by the single toothed belt. Torque input to the torque input unit is transmitted to the bolt tightening mechanisms by the toothed belt, and used to simultaneously tighten, for example, seven bolts. Because, torque can be simultaneously transmitted to plural bolt tightening mechanisms using a single belt, the number of components is reduced and the size, weight and cost are reduced and ease of use is improved.

Abstract: A carburizing and hardening method enhances strength while sufficiently reducing hardening strain, without increasing the production cost, and a carburized and hardened member produced thereby. The raw material is an alloy steel which contains Fe as a main component, 0.10 to 0.50 wt. % C and 0.50 to 1.50 wt. % Si and having a hardenability J, based on an end quenching test, in a range of 35 to 50 (at 12.5 mm). After the raw material is formed into the desired shape, a carburized layer is formed by carburizing in an oxidation inhibiting atmosphere. After the carburizing, quenching is performed with cooling, uninterrupted by temperature rise, from a pearlite transformation point (A1 point) to a martensite transformation start point (Ms point), and with a severity of quenching H in a range of 0.01 to 0.08 (cm?1).
