The NC turret punch machine decompressor with spring mechanism of the present utility model, operation principle is as follows.
1., during inoperative stroke 1, spring mechanism moves
As shown in Figure 10, when stamping machine is positioned at inoperative stroke 1, drift is positioned at top dead-centre, and the height in distance plate face is
H0, arc chute two and pin are in position shown in Figure 11.Motor is driven to drive nut, bevel gear one with ω by Timing Belt one0Rotation
Turning, screw rod is downwards with V1Speed moves downward, and drift is with V0Speed moves downward.Bevel gear one engages with bevel gear two, bevel gear
Two with ω1Speed rotates, and bevel gear two drives the synchronous pulley hinged with the mandrel of fork (to be provided above with by Timing Belt two
Arc chute two) with ω2Speed rotates.Arc chute two and pin-shaped grooving wheel set, bevel gear two rotarily drive fork with ω2
Rotate.Sharp shape angle theta between spring and fork is gradually reduced.
Along with drift moves downward, as shown in figure 12, the height in distance plate face is h1, and the height in drift distance plate face is gradually
Reduce.
During drift moves downward, arc chute two and pin are in position shown in Figure 13；Rotating shaft through B point, is slided to C by A point
Point, fork rotates, and fork and spring have individual critical point, spring and fork conllinear during critical point, after critical point is spent, rotating shaft meeting
Sliding to C point at a high speed, the now motion of slide block is driven by spring force completely, and before critical point, the motion of slide block is mainly passed by screw thread pair
Dynamic being driven, spring mechanism effect is little.
Sharp shape angle theta between spring and fork is gradually reduced, when the height in drift distance plate face is reduced to 0, on spring
The rotating shaft arcuately chute one of end is with speed V5Accelerating to slide (namely by A B C point), fork is with ω3Accelerate to rotate, sliding
Block is with speed V4Quickly to left movement, drift is with speed V6Accelerated motion.V now6Mainly driven realization by spring force, than
Drive motor-driven speed V0Substantially exceed very big, for the rapid movement of inoperative stroke 1, until drift with web contact is
Only.
2. impulse stroke, drives motor effect
As shown in figure 14, drift is under the effect of spring mechanism, and sharp downward movement also touches sheet material.Now slide block with
Pressure angle α between upper level guide rail is less, it is possible to form self-locking.I.e. under the effect of stamping press, slide block will not to left movement,
No matter the size of blanking pressure.Impulse stroke starts, and now the spring mechanism on right side forms self-locking, and the screw drive of the side that keeps left realizes
Punching press.
As shown in figure 15, after sheet material thrusts, blanking pressure momentary loss, drive motor stalls, left side screw rod stops fortune
Dynamic.Right side spring mechanism continues motion under spring force, until arc chute two contacts in position shown in Figure 16 with pin,
Play position-limiting action, reach bottom dead centre.
Inoperative stroke 2, drift is contrary with above-mentioned motor process to the motion of top dead-centre from bottom dead centre, and principle is identical, this
Place does not elaborates.
Preferred implementation of the present utility model described in detail above, but, this utility model is not limited to above-mentioned reality
Execute the detail in mode, in technology concept of the present utility model, the technical solution of the utility model can be entered
The multiple equivalents of row, these equivalents belong to protection domain of the present utility model.
