Problems solved by technology

However, there are still the following deficiencies: 1. In the above technical solution, because the entire stroke of the punch is driven by a motor, the entire stroke of the punch includes a working stroke (that is, a stamping stroke, the following is similar) and a non-working stroke ( That is, non-stamping stroke, the following is similar), in which the working stroke is very short, while the non-working stroke is very long, and the working stroke accounts for about 1 / 6~1 / 10 of the entire stroke, so the punching speed is low and the processing efficiency is affected
[0003] 2. The linearity of punching force output is poor
[0004] 3. The adaptability to different plate thickness is poor. In order to adapt to different plate thickness changes, the stroke and motor power of the mechanism are usually increased.
[0005] increased energy consumption

Embodiment 1

[0057] Such as figure 1 As shown, the swing frame is L-shaped, the tip corner of the swing frame is upward, and the tip corner is hinged with the top of the punch; one of the free ends of the swing frame is hinged with the main link in the threaded auxiliary drive; the swing frame The other free end is hinged with the auxiliary link in the spring mechanism.

Embodiment 2

[0059] The swinging frame is a V-shaped frame or a triangular frame, and the V-shaped frame or the triangular frame has three hinge points, and the three hinge points are respectively hinged with the main connecting rod, the punch and the auxiliary connecting rod.

Embodiment 3

[0061] The swing frame is a linear rod, and the linear rod is provided with two hinge points, one hinge point is hinged with the punch; the other hinge point is hinged with the main connecting rod and the auxiliary connecting rod respectively.

[0062] Such as Figure 6 As shown, the thread auxiliary transmission includes a nut 32 , a screw rod 31 , a main connecting rod 35 , a synchronous belt 1 34 and a drive motor 33 .

[0063] The height position of the nut is fixed, the screw rod cooperates with the nut, and the screw rod can be lifted and locked in height under the action of the driving motor. Preferably, a set of timing belts is set on the outer periphery of the nut.

[0064] Such as image 3 As shown, the drive motor drives the nut to rotate through the synchronous belt, the nut rotates to drive the screw to move up and down, the screw moves up and down to drive the main connecting rod to move, and the swing frame (equivalent to a lever) realizes the up and down driv...

Abstract

The invention discloses a high speed punching mechanism for an all-electric servo press. The high speed punching mechanism comprises a puncher pin, a thread pair transmission device, a swing support, a spring mechanism and a spring driving device. The thread pair transmission device comprises a nut, a screw and a driving motor; and the height position of the nut is fixed, and the screw can be lifted. The spring mechanism comprises a spring height permitted locking device, a swing rod and a spring; a first arc-shaped sliding groove is formed in one end of the swing rod; one end of the spring is provided with a rotating shaft, and a groove wheel pair can be formed by the first arc-shaped sliding groove and the rotating shaft; and the top height position of the spring mechanism can be fixed and locked through the spring height permitted locking device. By means of the spring driving device, the swing rod can swing, and the groove wheel pair can be further formed by the rotating shaft and the first arc-shaped sliding groove. By means of the above structure, the driving motor is adopted for driving in the working stroke, a spring mechanism is adopted in the non-working stroke, the machining efficiency can be obviously improved, and energy consumption is reduced. The high speed punching mechanism can be suitable for changes of different plate thicknesses and different punching forces, the linearity of the output force is good, and the high speed punching mechanism can be suitable for high-speed and heavy-load application occasions.

Description

technical field [0001] The invention relates to a stamping device of a press, in particular to a high-speed stamping mechanism for an all-electric servo press. Background technique [0002] Servo press is an important equipment in the field of sheet metal processing. The existing technology adopts the planar linkage mechanism driven by a single motor or a double motor. This technical solution has a simple structure, good reliability, and is easy to control. It is widely used at present. However, there are still the following deficiencies: 1. In the above technical solution, because the entire stroke of the punch is driven by a motor, the entire stroke of the punch includes a working stroke (that is, a stamping stroke, the following is similar) and a non-working stroke ( That is, non-stamping stroke, the following is similar), in which the working stroke is very short, while the non-working stroke is very long, and the working stroke accounts for about 1 / 6~1 / 10 of the entire ...
