Abstract
The utility model relates to a turning balance mechanism of a plate bending machine, which is characterized by mainly comprising a sprocket lever fixedly mounted on a plate bending machine support. A chain is connected to a sprocket of the sprocket lever, the lower end of the chain is connected with a pull bar, and a spring combination is mounted between the pull bar and the plate bending machine support. When the support rotates, the sprocket drives the chain to drive the pull bar in motion, the pull bar compresses springs, spring force applied to the pull bar from the spring combination is applied to a turning mechanism so as to balance inertia moment and gravitational moment, thereby the support is balanced and stable and free of impact during turning, and equipment damage is avoided. Therefore, unbalanced inertia moment and gravitational moment of the turning mechanism can be reduced or eliminated by the aid of the turning balance mechanism with the strucutre, and the turning balance mechanism has the characteristic of self-adapting balance, and has the advantages of simple, novel and smart structural design, low production cost, stability and reliability in operation, quickness and convenience in production and application, and the like.
Description
Technical field
The utility model belongs to the mechanical balance technical field, particularly relates to a kind of veneer reeling machine upset balanced controls.
Background technology
After veneer reeling machine has been rolled up steel plate,, the bearing of middle top roll one end need be tumbled for workpiece is taken out from veneer reeling machine quickly and easily.Switching mechanism is when overturning, the unbalance inertia force square and the gravitational moment that are produced, switching process is quickened, in switching mechanism, cause additional dynamic pressure, frictional force in the meeting increase kinematic pair and the internal stress in the member, impact to mechanism simultaneously, reduce mechanical efficiency and service life.The purpose of veneer reeling machine upset balanced controls is exactly to manage the unbalance inertia force square of switching mechanism and gravitational moment balance in addition, to eliminate or to reduce its harmful effect.
In common mechanical, because the structure of each member and the difference of forms of motion, the moment of inertia that it produced is also different with balance method, roughly adopts to increase or reduce method for quality on member to give balance.Because the particularity of veneer reeling machine switching mechanism, said method are difficult to be suitable for, so the utility model, has designed the upset balanced controls that a cover has the adaptive equalization characteristics according to the particularity of switching mechanism structure.
Summary of the invention
The utility model provides a kind of unbalance inertia force square and gravitational moment of eliminating or reducing switching mechanism to add for solving the technical problem that exists in the known technology, has the veneer reeling machine upset balanced controls of adaptive equalization characteristics.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of veneer reeling machine upset balanced controls, it is characterized in that: these upset balanced controls mainly comprise the chain turbine/lever that is fixedly mounted on the veneer reeling machine bearing, be connected with chain on the sprocket wheel of chain turbine/lever, the lower end cylinder lever connecting rod of chain is equipped with cluster spring between pull bar and the veneer reeling machine frame.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, the chain turbine/lever promptly is installed on the veneer reeling machine bearing, be connected with chain on the sprocket wheel of chain turbine/lever, the lower end cylinder lever connecting rod of chain is equipped with cluster spring between pull bar and the veneer reeling machine frame.When bearing rotated, sprocket wheel drove chain, made the pull bar motion, pull bar compression spring, give the spring force of pull bar by cluster spring, act on switching mechanism, come balance inertial force square and gravitational moment, thereby when making the bearing upset, balance and stability does not have and impacts, and avoids device damage.Therefore the unbalance inertia force square and the gravitational moment of switching mechanism can be eliminated or reduce to said structure, have the adaptive equalization characteristics, the utility model also has simple, the novelty, ingenious of structural design in addition, and production cost is low, plurality of advantages such as working stability is reliable, and production application is efficient and convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, bearing; 2, chain turbine/lever; 2-1, sprocket wheel; 3, chain; 4, pull bar; 5, frame; 6, cluster spring.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of veneer reeling machine upset balanced controls, these upset balanced controls mainly comprise the chain turbine/lever 2 that is fixedly mounted on the veneer reeling machine bearing 1, be connected with chain 3 on the sprocket wheel 2-1 of chain turbine/lever 2, the lower end cylinder lever connecting rod 4 of chain 3 is equipped with cluster spring 6 between pull bar 4 and the veneer reeling machine frame 5.
Its operation principle is: when bearing rotated, sprocket wheel drove chain, made the pull bar motion, pull bar compression spring, give the spring force of pull bar by cluster spring, act on switching mechanism, come balance inertial force square and gravitational moment, thereby when making the bearing upset, balance and stability does not have and impacts, and avoids device damage.Be reversed part comprise bearing and with half gear of its thread connection, flip angle is 0 to 75 degree, is reversed part in switching process, the gravitational moment that the moment of inertia that needs the moment of balance mainly to comprise to be reversed part to rotate to produce and its deadweight produce.Because the element structure out-of-shape, the gravity acting force arm changes at rotation process, so cause the size variation of unbalanced moments, also is difficult for by directly calculating.In the utility model, when being reversed the part original state, unbalanced moments minimum, the decrement minimum of spring; After flip angle reaches maximum 75 degree, unbalanced moments maximum, the decrement maximum of spring.Cluster spring is compressed the spring force of generation, correspondingly changes along with the variation of unbalanced moments size, has realized the adaptive equalization to unbalanced moments.
