Description
Technical field
The present invention relates to a kind of forcing press, particularly the feed mechanism on the NC turret punch machine.
Background technology
The feed spool of NC turret punch machine comprises seesaw Y-axis on the direction of X-axis on the planker side-to-side movement direction and crossbeam; Its structure mainly comprises X-axis transmission mechanism, Y-axis transmission mechanism and crossbeam three parts.Current, two feed spools of NC turret punch machine generally all adopt the direct-connected drives structure of single servo motor list ball-screw; Wherein, X-axis: ball-screw is installed on the crossbeam, and line slideway also is housed on the crossbeam, and planker is installed on the line slideway slide block, and with the line slideway guiding, planker is rigidly connected by a connection piece and ball-screw nut; The positive and negative rotation of servomotor drags the planker linear reciprocating motion; Y-axis: ball-screw is installed on the fuselage, also parallel two line slideways that are equipped with on the fuselage, and crossbeam is installed on the slide block of two line slideways, with a connection piece crossbeam is connected with ball-screw nut; The positive and negative rotation of servomotor drags the crossbeam linear reciprocating motion.
There is following defective in above driving mechanism:
1.. the ball-screw screw mandrel is slender axles, poor rigidity, there is vibration during running, when running up, vibrates more violent, had a strong impact on transmission accuracy, particularly the X-axis stroke is long, and required ball-screw screw mandrel is also long, and rigidity is lower, the rotating speed that can provide is lower, has seriously restricted the raising of feeding speed.
2. .Y axle ball-screw nut directly links to each other with crossbeam, and the Y-axis driving force has strengthened the vibration of crossbeam, causes screw mandrel and crossbeam to produce resonance, makes on the feeding speed not come.
3.. the X-axis load, still the Y-axis load all acts on the crossbeam, so that the rigidity of crossbeam is wanted is high, could guarantee operating accuracy.For improving the rigidity of crossbeam, can increase the weight of crossbeam unavoidably.Generally speaking, do not vibrate for guaranteeing that crossbeam is in operation, being used for the steel plate of welding beam needs more than 8mm.The feeding operating mode of NC turret punch machine is to operate in all the time under the acceleration and deceleration state, and the increase of crossbeam weight has greatly reduced feeding efficient.
Along with the development in market, the client is more and more higher to the requirement of NC turret punch machine working (machining) efficiency.For satisfying this demand, the feed mechanism of NC turret punch machine need possess dynamically high at a high speed, and original feed mechanism has not satisfied the new demand of market to NC turret punch machine.
Summary of the invention
The purpose of this invention is to provide a kind of high speed feed mechanism, can improve the feeding speed of plate, improve the punch press operating efficiency.
