Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-3, the present invention provides the following technical solutions: a novel coil spring cutting device comprises a cutter 1, a cutter driving assembly 2 and a cutting table 3 matched with the cutter 1, wherein the cutter 1, the cutter driving assembly 2 and the cutting table 3 are fixedly arranged on a back plate 4, the back plate 4 is movably connected with a frame body 5, and a driving element 6 for lifting the back plate 4 is arranged on the frame body 5; the cutter driving assembly 2 comprises a gear transmission system 7, a crank cam device 8, a cutter holder 9 connected to the moving end of the crank cam device 8 and a cutter holder slide way 10, a wedge-shaped groove 12 is formed in a cutter block 11, a wedge-shaped block 13 is arranged in the wedge-shaped groove 12, a locking element 14 is arranged at the position, located in the wedge-shaped groove 12, of the cutter block 11, and the wide part of the wedge-shaped block 13 extends out of the cutter holder 9 and is connected with the cutter 1 phase.
When the spring wire cutting machine is used, the cutter driving assembly 2 drives the cutter 1 to be close to or far away from the cutting table 3 so as to cut off the spring wire. When the diameter of spring increases, through drive element 6 drive backplate 4 relative framework 5 upward movement, because cutter 1, cutter drive assembly 2 and the equal fixed mounting of cutting platform 3 are on backplate 4, so the position of cutting off the spring silk has been promoted the adjustment that can be convenient make and be adapted to different diameter spring silks this moment. Furthermore, since the cutter 1 is not adjusted frequently in this embodiment, the cutter 1 can be fixed to the cutter block 11 through the wedge groove 12 and the wedge block 13.
