Description
Technical field
This application involves a kind of wire cutting mechanism of wire of low noise type high speed spring coiling machine, belong to wire rod processing be wound into it is special
The metal machining technical field without cutting substantially of shape.
Background technique
Spring coiling machine is the mechanical equipment for producing spring, and steel wire line sending from coil holder first passes around alignment, and then steel wire carries out
Coil diameter variable diameter is finally cut off the production for completing a spring by cutter.
Current spring coiling machine most common on the market is by taking TK-208 type spring coiling machine as an example, and two axis, the 208 type spring coiling machine is with two
Servo motor completes all function and movement, solve to produce different types of tension spring, pressure spring, torsional spring, straight spring, pagoda spring,
Cydariform spring, concave spring etc., all function connects are combined with two servo motor mechanical parts, relevant dynamic to complete
Make.But the defect of the spring coiling machine is it is also obvious that be wherein directed to cut off operation, defect, which is especially apparent, to be showed themselves in that
(1) cutting use oscillates formula cutting mechanism, and accessory is more, and can only realize swing, therefore appear cut off
It is the cutting that can only realize both direction in effect；
(2) cabinet airframe structure uses the structure of two blocks of wallboards and other board material splices of left and right, and wallboard is mutually only with plate
Vertical, there are connection errors, and consistent low precision is not achieved in the degree of balance, concentricity, precision；
(3) the main axis lengths overlength such as cut-out axle, inlet wire axis, the poor rigidity of axis are easily deformed, and influence axis precision, and above-mentioned
Long axis is driven by two spindle motors, and a large amount of accessory is needed in kinetic energy transmittance process.
Based on this, the application is made.
