摘要： The invention relates to a method for producing threads, especially internal screw threads (34), by means of a rotationally driven thread former (10) which drive the pitches of the screw thread outwardly in a non-cutting manner by pressure forming in and on the surface of the workpiece. The aim of the invention is to produce threads with various nominal diameters in a particularly economical manner and with improved structural quality. In order to achieve this, a shank tool (10) is fitted with profile projections which are arranged at a constant distance in relation to each other according to the type of thread milling cutter. Said profile projections (20) are formed in a continuous manner and have a variable radial extension on the periphery of the head of the thread (18), and are initially inserted into the tool at a point on the periphery (SU) of the workpiece bore in the workpiece. Said workpiece is arranged, preferably, at the full thread depth (TG), and a relative circular movement of 360° in relation to the axis (30) of the workpiece bore (16) is carried out maintaining the eccentricity (EX) of the rotational axis adjusted by the axis (30) of the workpiece bore (16), while the head of the thread also carries out a constant axial relative forward displacement movement (BV) corresponding to the thread pitch (P) which is to be produced.

摘要： Procedure for making a screw thread on a corrugated bar, in which procedure the thread is made on one end of the corrugated bar (7), in which procedure the end of the corrugated bar (7) is expanded by battering so that the cross-sectional area of the thread to be formed will be at least equal to the cross-sectional area of the rest of the corrugated bar (7), and in which procedure the thread is formed on the expanded end of the corrugated bar. The corrugation ribs (1) and flank fillets (2) are removed from the end of the corrugated bar (7). In addition, the end of the corrugated bar is expanded by hot battering.

摘要： An apparatus for automatically removing concrete from a screw-threaded bolt (17) of a screw-jack type support device ( A ) includes a rotatable tube (15) for receiving the screw-threaded bolt (17), a socket (16) formed on one end of the tube (15) for receiving the nut (19) of the jack device ( A ), and an arm (6) disposed in axial alignment with the tube (15) and movable toward and away from the tube (15) by a carriage (5) movable along a rail (3) by a piston and cylinder device (7). In use, the screw bolt (17) is inserted in the tube (15), and the nut (19) is fitted in the socket (16), and a base plate (18) of the jack device ( A ) is abutted agains the arm (6) so that when the tube (15) is rotated by a motor (23), the nut (19) is forcedly rotated and this forced rotation causes the concrete on the screw bolt (17) to be cracked and removed due to friction with the nut (19) as the screw-threaded bolt (17) is moved toward and away from the tube (15).

摘要： Provided is a thread forming tap that can suppress internal thread processing defects. A partial thread (33) is provided, in the axis (O) direction view, with a protrusion (33a) formed so as to protrude in the radial direction and a clearance section (33b) formed so as to have a smaller diameter than the protrusion (33a), and as a result of the foregoing, if a thread forming tap (1) rotates in a state where the inner circumferential surface of a pilot hole and the partial thread (33) come into contact, the protrusion (33a) of the partial thread (33) can be caused to engage with the inner circumferential surface of the pilot hole (an effect similar to thread being formed in the inner circumferential surface of the pilot hole by the screw thread of an engagement section (31) can be protruded). Due to this configuration, rubbing in a state where the partial thread (33) is pressed against the inner circumferential surface of the pilot hole can be suppressed, and as a result, chipping of the partial thread (33) can be prevented. Accordingly, it is possible to prevent fragments of the partial thread (33) from catching in the area between the inner circumferential surface of the pilot hole and the screw thread of the thread forming tap (1), enabling suppression of internal thread processing defects.
