摘要:
An optical recording medium-manufacturing apparatus which is capable of reducing wear of a cut-forming blade section used for forming a cut in a resin layer, without increasing the component costs of the apparatus. An ultrasonic horn includes a hollow-cylindrical cut-forming blade section for being pushed into a resin layer formed on one side of a disk-shaped substrate, thereby forming a circular cut in the resin layer. A control section controls motion of the ultrasonic horn caused by a moving mechanism. The control section causes the ultrasonic horn to be pushed in to the resin layer while causing ultrasonic vibration thereof to thereby form the cut, and while maintaining a state of ultrasonic vibration of the abutment section and a pushed-in state of the cut-forming blade section, causes the punching blade section to be pushed into the disk-shaped substrate, to form the central hole.

A punch includes a base, a plurality of punch pins, a lever and a plank. The base includes a lower member defining a plurality of holes and an upper member defining a plurality of holes corresponding to the holes defined in the lower member. Each of the punch pins is for insertion through one of the holes defined in the upper member and one of the holes defined in the lower member. The lever is pivotally mounted on the base. The plank defines a plurality of holes. The plank is movably attached to the lever between several positions in each of which it pushes a different set of the punch pins when the lever is operated.

Disclosed is a retainer device A for selectively changing the amount of projection of a punch 1 so that the punch projection amount is increased when the punch 1 is used for pressworking and, conversely the punch projection amount is decreased when the punch 1 is not used for pressworking In the retainer device A, guide pins 23 mounted on a cam 21 are moved in guide grooves 11 of a cam receiver 9 fastened to a punch holding body 2 so that the punch holding body 2 is forcibly moved up and down thereby causing the position of the punch 1 to switch between a use position and a non-use position.

A plunger assembly is provided for gripping blanking material or blanking scrap during a blanking operation. The plunger assembly includes a base member; a pivoting gripper or plunger member, and a pair of connecting legs connecting the pivoting gripper member to the base member. The assembly is adapted to pivot with respect to at least one of the base member and the pivoting gripper member through a predetermined pivot angle range for changing a distance between the base member and the pivoting gripper member. By pivoting, a folding and unfolding of the plunger assembly can be effected during a blanking operation.

A powder material application apparatus capable of applying powder material uniformly onto lower surfaces of plural upper punches, upper surfaces of plural lower punches and inner circumferences of plural dies of a tabletting machine. Powder material is applied on a material contacting surface of the lower punch by spraying powder material mixed with air from a powder material spray port for lower punch of a powder material application part for lower punch. Powder material is applied on a material contacting surface of the upper punch wherein powder material is not applied enough according to gravity by spraying powder material mixed with air from a powder material spray port for upper punch while the upper punch moves from an initial end to a terminal end of the powder material spray port for upper punch. The powder material spray port for upper punch is provided along the rotary orbit of the upper punches and is elongated more than the powder material spray port for lower punch.

A stiffening assembly is provided for stiffening an outer frame for a lower blanking tool of a carton die cutting machine to discourage the flexing thereof. The stiffening assembly includes an elongated rod and a clamping piece defining a vertically extending inner face, an opposite vertically extending outer face, and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face. A jaw element is operatively connected to the clamp piece so as to define a clamp cavity therebetween. The jaw element is movable between a clamping position for retaining a portion of the elongated rod in the clamp cavity and a release position.

A craft punch aid includes a base portion and a lever portion pivotally attached to the base portion. A rotatable pressure head assembly is attached to the lever portion, the pressure head assembly includes a pressure stub for accommodating punches of differing heights. The base portion may include a pivot device for producing designs of differing radii on a work-piece, and the craft punch aid may include a straight guide for attachment to the base portion for enabling straight-line punching of a work-piece.

The feeding apparatus is driven intermittently by a electric servomotor with a drive shaft. The upper feeding roller is held clamped in a bipartite upper shaft assembly between a shaft portion located adjacent the electric servomotor and a shaft portion located remote from the electric servomotor. The lower feeding roller is held clamped in a bipartite lower shaft assembly between a shaft portion located adjacent the electric servomotor and a shaft portion remote from the electric servomotor. The upper shaft assembly is supported in a rocker. The transmission of the driving force from the electric servomotor to the upper shaft assembly proceeds via a Oldham-type coupling. The transmission of the driving force from the upper shaft assembly to the lower shaft assembly proceeds via spur gear wheels. The connection between the drive shaft of the electric servomotor and the upper shaft assembly is accomplished by a multi-part clamping sleeve device. The one spur gear wheel and a part of the Oldham-type coupling are made integral with a part of the multi-part clamping sleeve device.

The present invention relates to a punch (30) and punch assembly (2) for use in a tool (1) for joining ductile materials, such as metal sheets (7,8), in a lance joint or a clinch joint. The punch (30) has a punch body (31) formed around a punch axis (5). Two punch tips (34,34null) extend in opposite directions from the punch body (31) along the punch axis (5). The punch body has one or more load engagement features (41,41null) by which a punch force for joining the ductile materials (7,8) is imparted to the punch body (31). When one punch tip (34) becomes worn, the punch (30) can be removed from a punch holder (25), inverted and rejoined to the punch holder (25) so that the other of the punch tips (34null) can be used to join ductile material (7,8)

The invention relates to a paper punch comprising a cover having a push button movably projected from the top, and a cutter coupled to the push button and having a longitudinal hole therethrough; a substantially parallelepiped base being coupled to the cover and having a second opening on the top for permitting the cutter to pass through and a receiving space in communication with the second opening; and a central needle in the receiving space passed through the second opening and being operable to punch a sheet of paper placed on the base and to secure the sheet of paper to the base so that the cutter is moved as the push button is pressed down, and in response, the needle moves into the longitudinal hole to activate the cutter for cutting the sheet of paper.
