Sheave pair as shown in Figure 9.
The full electric servo forcing press high speed stamping mechanism of the present invention, operation principle are as follows.
1. during inoperative stroke 1, spring mechanism motion
As shown in Figure 10, when stamping machine is located at inoperative stroke 1, drift is located at top dead-centre, and the height apart from plate face is
H0, arc chute two is with pin in position shown in Figure 11.Motor drives nut, bevel gear one with ω by timing belt one0Rotation
Turn, 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 be hinged with the mandrel of swing rod by timing belt two（It is provided with above
Arc chute two）With ω2Speed rotates.Arc chute two and pin-shaped grooving wheel set, the rotating band driven fork of bevel gear two is with ω2
Rotation.Sharp shape angle theta between spring and swing rod is gradually reduced.
As drift moves downward, as shown in figure 12, the height apart from plate face is h1, and drift is gradual apart from the height of plate face
Reduce.
During drift moves downward, arc chute two is with pin in position shown in Figure 13；Rotating shaft, through B points, slides to C by A points
Point, swing rod rotate, and swing rod and spring have an individual critical point, and spring is conllinear with swing rod during critical point, after critical point is spent, rotating shaft meeting
C points are slided at a high speed, the now motion of sliding block is driven by spring force completely, and before critical point, the motion of sliding block is mainly driven by screw thread pair
Dynamic, spring mechanism effect is little.
Sharp shape angle theta between spring and swing rod is gradually reduced, when drift reduces apart from the height of plate face, spring upper end
Rotating shaft arcuately chute one with speed V5Accelerate to slide（--- B --- C points namely by A）, swing rod is with ω3Accelerate rotation, sliding block with
Speed V4Quickly to left movement, drift is with speed V6Accelerate.V now6Mainly drive what is realized by spring force, than driving
Motor-driven speed V0It is obvious to be higher by very greatly, it is the quick motion of inoperative stroke 1, untill drift and web contact.
2. impulse stroke, motor effect
As shown in figure 14, for drift in the presence of spring mechanism, sharp downward movement simultaneously touches sheet material.Now sliding block with
Pressure angle α between upper level guide rail is smaller, can form self-locking.I.e. in the presence of stamping press, sliding 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 for the side that keeps left is realized
Punching press.
As shown in figure 15, after sheet material is thrust, blanking pressure momentary loss, motor stops operating, and left side screw rod stops fortune
It is dynamic.Right side spring mechanism continues to move under spring force, until arc chute two contacts with pin in position shown in Figure 16,
Position-limiting action is played, reaches bottom dead centre.
Inoperative stroke 2, motion of the drift from bottom dead centre to top dead-centre with above-mentioned motion process on the contrary, principle is identical, this
Place does not elaborate.
The preferred embodiment of the present invention described in detail above, still, the present invention are not limited in above-mentioned embodiment
Detail, in the range of the technology design of the present invention, a variety of equivalents can be carried out to technical scheme, this
A little equivalents belong to protection scope of the present invention.
