Abstract
The invention relates to a tool for realising a press quenching and tempering method for a rotational symmetric tool, in particular for a gear wheel, wherein the tool is at least in part manufactured as an additive and wherein, in an additively manufactured area of the tool, is formed at least one pipe for guiding a fluid.
Claims12
A tool for realising a press quenching and tempering method for a rotational symmetric workpiece, comprising:
- a mounting comprising an additive manufactured part;
- and
- at least one cooling channel comprising portions, the at least one cooling channel present within said additive manufactured part, wherein
- the at least one cooling channel is a clearance and/or recess defined by said additive manufactured part,
- each of the portions are a respective contact area or in proximity of the respective contact area of the additive manufactured part and a workpiece surface, the proximity allowing for thermal transfer between the portions and the respective contact areas, the at least one cooling channel is configured such that a first angle of the at least one cooling channel relative to the workpiece surface at a first portion of the portions is different from a second angle of the at least one cooling channel relative to the workpiece surface at a second portion of the portions, and
- the tool further comprising at least two pieces couplable with each other.
A tool for realising a press quenching and tempering method for a rotational symmetric tool, wherein at least a portion of the tool is an additive manufactured part wherein, at least one pipe is formed in the additive manufactured part, the at least one pipe is for guiding a fluid, the at least one pipe comprising pipe portions, wherein each of the pipe portions are a respective workpiece contacting surface of the tool or in proximity of the respective workpiece contacting surface, the proximity allowing for thermal transfer between the pipe portions and the respective workpiece contacting surfaces, the at least one pipe is configured such that a first angle of the at least one pipe relative to the respective workpiece contacting surface at a first pipe portion of the pipe portions is different from a second angle of the at least one pipe relative to the respective workpiece contacting surface at a second pipe portion of the pipe portions.
A tool for realising a press quenching and tempering method for a rotational symmetric tool, wherein at least a portion of the tool is an additive manufactured part wherein, at least one pipe is formed in the additive manufactured part, the at least one pipe is for guiding a fluid, the at least one pipe comprising pipe portions, wherein each of the pipe portions are a respective workpiece contacting surface of the tool or in proximity of the respective workpiece contacting surface, the proximity allowing for thermal transfer between the pipe portions and the respective workpiece contacting surfaces, the at least one pipe is configured such that a first angle of the at least one pipe relative to the respective workpiece contacting surface at a first pipe portion of the pipe portions is different from a second angle of the at least one pipe relative to the respective workpiece contacting surface at a second pipe portion of the pipe portions, and the tool comprises at least two pieces couplable with each other.
