The invention relates to an automated punching station for the production of punched components for prosthetic surgery instruments, in particular for instruments able to mill/cut or otherwise carry out tissue removal processes in preparation for, or in the context of, prosthetic surgery operations. The invention also concerns a method to produce said punched components, and a punched component thus obtained.

A method for producing a spindle nut (10) for a ball screw (12) is provided, having the following steps: providing a substantially cylindrical workpiece (50) with first and second end faces (46, 44) and a lateral surface (14), shaping the workpiece (50) by pressing in an axially symmetrical central opening (16) and by simultaneously pressing in at least one first (18) and one second (20) channel which are arranged axially in parallel in the lateral surface (14) of the workpiece (50), the central opening (16) and the channels (18, 20) being open toward the first end face (46), introducing an internal thread (34) into the central opening (16), and introducing at least two radially running through-openings (22, 24) at least into the first channel in the form of a transfer channel for receiving diverting inserts (26, 28). A spindle nut (10) produced by the method and to a ball screw (12) having such a spindle nut (10) are also provided.

A machining apparatus includes a movement direction converting mechanism that converts lowering movement of a first punch into raising movement of a second punch and converts lowering movement of the second punch into raising movement of the first punch. The first punch and the second punch are raised and lowered in an alternating manner by this movement direction converting mechanism. Accordingly, machining by the first punch and machining by the second punch are performed individually.

An outlet cutter for cutting an outlet opening in an eavestrough has a frame including a trough opening therein arranged to receive the eavestrough therethrough. A female die including a die opening is supported on the frame directly below the trough opening so as to be arranged to be located directly below an eavestrough received through the trough opening. A male die is supported on the frame so as to be movable relative to a female die between a disengaged position spaced above the female die and a punching position fully received within the die opening in the female die using a screw. The frame is self-supported on the eavestrough for sliding. The male die has four corner portions, each formed by two side cutting edges which are sloped downwardly and outwardly towards a respective apex, with two opposed apexes protruding beyond a remainder of the die.

The invention relates to the field of jewelry processing, in particular to a hole positioning device for jewelry processing, which includes a main body and an operating cavity provided in the main body. A support plate is slidably disposed in the operating cavity and is located in the operating cavity. A sliding plate below the support plate, a cylinder is fixedly arranged in the sliding plate, and a through hole is formed in the cylinder, and a drilling positioning device for jewelry processing provided by the present invention can realize the ordering of jewelry. Perforating, a circulating water cooling device is installed in the equipment, which can cool the jewelry during cutting, so as to prevent the drill bit from overheating to affect the cutting effect. At the same time, the fixing device set in the equipment can easily fix the jewelry, and it automatically locates when drilling. The efficiency is high, the equipment can collect the jewelry debris in the cooling liquid, avoid the loss of property, and facilitate the production and promotion.
