Abstract
A device and a method for controlled setting of a coil spring, enabling a coil spring to be blocked in controlled manner with a selected compression length, in particular when compression with touching turns is unfavorable. According to the invention, the device comprises a first support configured to hold the first end of the spring and a second support configured to hold the second end of the spring, the first and second supports being configured to move relative to each other; the device further comprising at least one insertable rest configured to be inserted between certain turns of the spring during compression of the spring.
Claims12
A controlled setting device for fabricating a coil spring, the device being configured to compress said spring and to control its shape during compression, the device comprising a first support configured to hold a first end of the spring and a second support configured to hold a second end of the spring, the first and second supports being configured to move relative to each other, wherein the device further includes at least one insertable rest configured to be inserted between certain turns of the spring during compression of the spring, and wherein the insertable rest is mounted on a carriage configured to enable said insertable rest to follow the movement of the turns of the spring during compression of the spring.
A controlled setting method for setting a coil spring with a controlled setting device configured to compress the spring and to control its shape during compression, the method comprising the following steps:
- installing the spring between first and second supports of the device, wherein the first support is configured to hold a first end of the spring and the second support is configured to hold the second end of the spring, and the first support and the second support are movable relative to each other, wherein the device further includes at least one insertable rest configured to be inserted between certain turns of the spring during compression of the spring, and wherein the insertable rest is mounted on a carriage configured to enable said insertable rest to follow the movement of the turns of the spring during compression of the spring;
- compressing the spring by moving the first and second supports relative to each other;
- decompressing the spring;
- and
- removing the spring as treated in this way;
- wherein the method further comprises installing at least one insertable rest in certain positions corresponding to certain gaps that extend between the turns of the spring;
- and
- wherein the spring is compressed until all of the turns and said at least one insertable rest are in touching contact with one another.
