Abstract
The invention discloses a transmission mechanism of a cutter rest transverse slide block of a steel plate net punching and shearing machine, which is characterized by comprising a cam mechanism, a lever mechanism with one end connected to the cam mechanism and a push-and-pull rod with one end rotatably connected to the lever mechanism. A conjugate cam mechanism, a stepless adjustable lever and a rod end bearing are connected, thus a gap in transmission is eliminated; and by using the characteristics of the cam, velocity and acceleration of starting and stopping the motion of a driven member are zero, rigid shock of members is avoided, noise is lowered, positioning accuracy is improved, abrasion in moving is reduced, and stable work is achieved. The transverse slide block can be pushed to reciprocate by only less power.
Description
Technical field
The present invention relates to a kind of transmission mechanism of expanded metal lath punching and shearing machine, specifically relate to a kind of transmission mechanism of expanded metal lath punching and shearing machine knife rest cross slider.
?
Background technology
Existing expanded metal lath punching and shearing machine is produced expanded metal lath with upper slitter alternation position form, have a promotion to have the transmission mechanism of the sode slip piece of upper slitter.This transmission mechanism generally adopts eccentric wheel or cam to add the back-moving spring form.This mode required thrust will overcome the reset force of back-moving spring, and power requires bigger, and causes motion unbalance, and is particularly evident when alternating quantity is big, the serious wear of mechanism, and noise increases, and positioning accuracy is low.
?
Summary of the invention
The present invention seeks to provides a kind of wearing and tearing little at the defective that prior art exists, and noise is low, the precision height, and power requires low transmission mechanism.
The present invention adopts following technical scheme for achieving the above object:
A kind of transmission mechanism of expanded metal lath punching and shearing machine knife rest cross slider, it is characterized in that: described transmission mechanism comprises cam mechanism, an end is connected the pull bar that leverage on the described cam mechanism and an end are rotatably connected on the other end of described leverage.
It is further characterized in that: described cam mechanism comprises frame, and the conjugate cam that rotates in described frame and two are fixed in the described frame and the tangent roller of described conjugate cam periphery.
Described leverage is L shaped, and two ends can be axis swing with fixing turning cylinder.
Connect by rod end bearing between one end of described pull bar and the leverage, the other end is connected with cross slider.
Be provided with the adjustment screw between one end of described pull bar and the leverage
The present invention utilizes conjugate cam mechanism, electrodeless adjustable lever, rod end bearing connects, and has eliminated the gap between transmission, utilizes the characteristic of cam simultaneously, speed and acceleration that driven member motion initial sum is stopped are zero, avoid the rigid shock of member, reduced noise, improved positioning accuracy, wearing and tearing when reducing motion, stable working.Make that only needing less power just can promote cross slider moves back and forth.

The specific embodiment
The transmission mechanism of expanded metal lath punching and shearing machine knife rest cross slider comprises that cam mechanism 1, one end is connected the pull bar 3 of the other end that leverage 2 on the cam mechanism 1 and an end be rotatably connected on leverage 2 as shown in Figure 1.Cam mechanism 1 comprises frame 5, and the conjugate cam 4 that rotates in frame 5 and two are fixed on frame 5 in and the tangent roller of institute's conjugate cam 4 peripheries.Leverage 2 is L shaped, and two ends can be axis swing with fixing turning cylinder 7.Connect by rod end bearing between one end of pull bar 3 and the leverage 2, the other end is connected with cross slider 9.
Conjugate cam 4 passes through two tangent with its periphery all the time roller 6 drive frames 5 motions when rotating, it is axis swing with turning cylinder 7 that frame 5 drives leverages, promotes pull bar 3 and makes traverse motion with the cross slider 9 that is connected pull bar 3 other ends.
Can adjust cross slider 9 reciprocating alternating quantities by regulating adjustment screw 8.
