Embodiment Construction

[0047] A particular aspect of an embodiment of the invention is illustrated below using the example of a vertically configured spring end grinding machine 100 for the dry machining of helical compression springs (also called springs for short). Set by the double-sided flat grinding method with an untensioned spring in the feed method. The machine is constructed as a single structure with two grinding spindles and two loading discs. The machine basically comprises a grinding unit 120 , a loading unit 150 and a control unit 165 for controlling the controllable components of said loading unit 150 and grinding unit 120 .

[0048]The grinding unit 120 has a grinding disc pair with two coaxially rotatable grinding discs 130 , 140 , between which a grinding space 135 is formed during operation of the machine. The upper grinding disc 130 is fastened to the lower end of an upper grinding spindle 132 , which is mounted with a vertical axis of rotation 134 in the upper part of the suppo...

Abstract

A method of grinding spring ends of helical compression springs is carried out using a numerically controlled spring end grinding machine having a grinding unit, a loading unit and a control unit that controls the loading unit and the grinding unit. The grinding unit has a pair of grinding wheels including two rotatable grinding wheels between which is formed a grinding space. The loading unit has at least one loading plate substantially rotatable axially parallel to the grinding wheels and has a plurality of out-of-axis spring receptacles, each to receive a helical compression spring.

Description

technical field [0001] The invention relates to a method for grinding a spring end of a helical compression spring according to the preamble of claim 1 and to a spring end grinder according to the preamble of claim 13 which is especially suitable for carrying out the method. cutting machine. Background technique [0002] Helical compression springs are machine elements that are required in large quantities and in different designs in many fields of application. Compression helical springs are required in large quantities in vehicle construction, for example as load springs or valve springs. A helical compression spring can be described as a helical or coiled compression spring made of wire with a spacing between the turns. [0003] Of particular importance for the safe function of the compression helical spring during intended use are the spring ends, ie the two axial end regions of the compression helical spring. The spring ends are used to transmit the spring force to t...
