A joining method for a medical device, in particular a surgical instrument or implant, with a shaft and an attachment to be secured on the shaft, the method having the following steps: heating the attachment or cooling the shaft, such that an internal diameter of an opening of the heated attachment is greater than an external diameter of the shaft, then placing the shaft into the opening of the attachment, and then cooling the attachment, so as to shrink the attachment onto the shaft in a manner substantially free of gaps, or heating the shaft, such that the shaft and the opening are connected by an interference fit. A corresponding medical device is produced by the joining method.

An induction heating device for a shrink-clamping and/or unshrink-unclamping of tools into and/or out of a tool holder, includes an induction heating unit having at least one induction coil configured to thermally expand at least a portion of a tool holder arranged in a receiving region of the induction heating unit, and includes at least one magnetic flux conducting unit for a conduction of a magnetic flux generated by the induction coil, having at least one magnetic flux conducting element, preferably supported movably relative to the receiving region and implemented at least to a large extent of a ferrite material, and includes a sleeve element, arranged on the magnetic flux conducting element and covers the magnetic flux conducting element on at least one side of the magnetic flux conducting element that faces toward the receiving region in at least one operating state of the magnetic flux conducting unit.

A method for connecting a first component to a second component to form an assembly forms a press fit connection between the first component and the second component, for which purpose the second component is produced having an annular component section. A recess is formed, in which the first component is at least partially arranged. At least the annular component section of the second component is produced as a sintered component and has net shape or near net shape quality at least in the region of the recess.

A joining device for joining components on a shaft, e.g., for joining camshaft components on a camshaft tube, is disclosed. The joining device includes a joining device body composed of a material with a heat expansion coefficient that is lower than 10.0 μm/m° C. The heat expansion coefficient of the joining device is smaller than that of the components and/or the shaft.

A method for manufacturing a hollow camshaft is provided, and more particularly, a method for manufacturing a combined hollow camshaft by an axial-compression upsetting-deformation technique. The present method solves a problem that the current camshaft manufactured in an internal high-pressure expansion manner in the prior art has the insufficient locking force to cause the loosening of a cam. The method is as follows: a camshaft is formed by combining two independent units, namely a cam and a shaft tube. Non-circular countersinks are distributed on two sides of the cam. Thrust steps are formed on the shaft tube correspondingly. The cam is placed between the two thrust steps of the shaft tube. The locking force is applied to the cam by utilizing the thrust steps on the two sides of the cam based on thermal expansion and contraction. Simultaneously, the thrust steps lock the cam with the countersinks.

A method for producing a shrink-fitted member by arranging a pillar shaped ceramic body inside a deep-drawn stainless steel pipe and shrink-fitting them. The method includes: a preparing step of preparing the deep-drawn stainless steel pipe produced by deep-drawing and the pillar shaped ceramic body; a heating step of heating the deep-drawn stainless steel pipe to 900° C. or more; and a shrink-fitting step of inserting the pillar shaped ceramic body into the heated deep-drawn stainless steel pipe and shrink-fitting them.

A cargo container loading and unloading system for a transportation system, the cargo container loading and unloading system including a loading zone; and at least one opening connecting the loading zone to a transportation tube of the transportation system.

There is provided a base-integrated blade manufacturing method for manufacturing a base-integrated blade by fixing a cutting blade having a circular opening to a base having an annular projection. The method includes a first step of preparing the base having the projection that has an outside diameter greater than a diameter of the opening of the cutting blade, and the cutting blade, a second step of lowering a temperature of the base and thus shrinking the base to have the outside diameter of the projection smaller than the diameter of the opening of the cutting blade, a third step of inserting the projection into the opening of the cutting blade, and a fourth step of raising the temperature of the base and thus expanding the base in such a manner that the cutting blade is fixed to the base.

A method of producing a clad billet includes heating a corrosion resistant alloy (CRA) cylinder having a hollow interior to expand its inner diameter; inserting a solid carbon or low-alloy steel (CS) material into the hollow interior of the heated (CRA) cylinder so that an outer surface of the (CS) material faces the inner diameter of the (CRA) cylinder; cooling the (CRA) cylinder to contract and shrink the inner diameter of the (CRA) cylinder onto the outer surface of the (CS) material creating an interference fit at an interface with the outer surface, resulting in a composite billet assembly; and hot extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder. The clad billet can be hot-rolled to form metallurgically-bonded clad bar, or can be cold pilgered/cold drawn to form a metallurgically-bonded clad pipe.

An induction heating system can be adapted for shrink fitting a plurality of different assemblies. A plurality of tooling units associated to respective ones of the assemblies, each one having an appropriately configured induction coil and holder, can be provided. A computer can be used to control the delivery of electrical power to the induction coil in accordance with a heating recipe, and can be provided with an input device for inputting an assembly identifier allowing the computer to operate the control based on the right heating recipe.
