Abstract

The utility model provides a spoke mechanism of bending, include the bottom plate and fix fixed plate on the bottom plate still includes die block and depression bar, the die block is fixed on the bottom plate, install cam and a pair of rocking arm on the side of fixed plate, the rocking arm passes through rotatable the installing on the fixed plate of second pivot, install the gyro wheel through the third pivot between the rocking arm, the cam acts on the gyro wheel with the rocking arm can make it wind second pivot swing, the fixed plate is put on the shelf and is equipped with the sleeve of rectangle, have one can follow its rectangle die shank that reciprocates in the sleeve, the die shank is located the gyro wheel below, the gyro wheel acts on the die shank makes its emergence reciprocate. The utility model has the advantages of with positive effect be: the utility model discloses a cam mechanism's rotation drives the gyro wheel swing, and the gyro wheel pushes down the die shank makes the die shank move down, just can bend to the spoke stock, and easy operation, machining efficiency is high.

Description

A kind of spoke bending mechanism
Technical field
The utility model relates to spoke technical field of processing equipment, particularly relates to a kind of spoke bending mechanism.
Background technology
In existing spoke manufacturing procedure, spoke stock one end enters bending process after hatting, and dogleg section is made up of stock fixed mechanism and Bending punch mechanism.Existing method is too complicated at bending equipment, and the size of bending is difficult to ensure unanimously, to bring a lot of inconvenience.
Utility model content
Problem to be solved in the utility model is to provide a kind of spoke bending mechanism, simple to operate, substantially increases working (machining) efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of spoke bending mechanism, comprise base plate and be fixed on the fixed head on described base plate, also comprise bed die and depression bar, described bed die is fixed on described base plate, one side of described fixed head is provided with cam and a pair rocking arm
Described rocking arm is arranged on fixed head by the second rotating shaft is rotating, is provided with roller between described rocking arm by the 3rd rotating shaft, and described cam acts on described roller and described rocking arm can make it around described second shaft swing;
The added sleeve being provided with rectangle of described fixed head, has the rectangle die shank that can move up and down along it in described sleeve, described die shank is positioned at below described roller, and described roller acts on described die shank makes it move up and down.
Further, described cam is installed on described fixed head by the first rotating shaft, and described cam is divided into peach tip and base portion, and described base portion is arranged with described first rotating shaft is concentric, and when described cam rotates, its peach tip acts on described roller makes it swing.
Further, the below of described die shank is provided with spring, and one end of described spring is fixed on described base plate, the other end and described die shank inconsistent.
Further, described cam is driven by motor or handwheel.
The advantage that the utility model has and good effect are:
(1) the utility model drives roller and rocking arm to swing by the rotation of cam mechanism, and roller presses down die shank and makes die shank generation upper and lower displacement, and when die shank moves down, just can carry out bending to spoke stock, simple to operate, working (machining) efficiency is high.
(2) below of die shank is provided with spring, and one end of spring is fixed on described base plate, the other end and described die shank inconsistent, by spring can play buffering and reset effect.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the top view of the part-structure that cam of the present utility model matches with roller.
In figure:
1, base plate; 2, fixed head; 3, cam; 4, the first rotating shaft; 5, the second rotating shaft; 6, rocking arm; 61, the 3rd rotating shaft; 7, roller; 8, die shank; 9, sleeve; 10, spring; 11, depression bar; 12, spoke stock; 13, bed die;
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Fig. 1 ~ 2: a kind of spoke bending mechanism, the fixed head 2 comprising base plate 1 and be fixed on described base plate 1, also comprise bed die 13 and depression bar 11, described bed die 13 is fixed on described base plate 1, one side of described fixed head 2 is provided with cam 3 and a pair rocking arm 6, described cam 3 is driven by motor or handwheel.
Described rocking arm 6 is arranged on fixed head 2 by the second rotating shaft 5 is rotating, is provided with roller 7 between described rocking arm 6 by the 3rd rotating shaft 61, and described cam 3 acts on described roller 7 and described rocking arm 6 can make it swing around described second rotating shaft 5;
The added sleeve 9 being provided with rectangle of described fixed head 2, the rectangle die shank 8 having can move up and down along it in described sleeve 9, described die shank 8 is positioned at below described roller 7, and described roller 7 acts on described die shank 8 makes it move up and down.In addition, the below of described die shank 8 is provided with spring 10, and one end of described spring 10 is fixed on described base plate 1, the other end and described die shank 8 inconsistent.
Described cam 3 is installed on described fixed head 2 by the first rotating shaft 4, and described cam 3 is divided into peach tip and base portion, and described base portion is arranged with described first rotating shaft 4 is concentric, and when described cam 3 rotates, its peach tip acts on described roller 7 makes it swing.
The course of work: spoke stock 12 is fixed on bed die 13 by depression bar 11, opens motor, cam 3 is rotated, thus drive roller 7 to swing, under the effect of roller 7, die shank 8 moves down, complete spoke bending, by the effect of spring 10, die shank 10 is resetted, repeated work.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
