Description

Winding mechanism for automatically rotating the end of spring wire

Technical content:

The present invention relates to the technical field of a compression spring manufacturing machine, and more particularly to a winding mechanism capable of automatically rotating a spring wire end.

Background technique:

The compression spring manufacturing machine (pressure spring machine) is a processing machine that can wind the spring wire. If the spring wire used has a wire diameter of no more than 5mm, it can be produced without a special winding mechanism. However, for a spring product with a wire diameter of more than 5mm, a large wire diameter of 5mm-20mm is often required. The worker uses a winding device to manually wind the fan into an arc shape or repeatedly operate the hydraulic cylinder or the motor to push the slider to drive the curve gauge and the curve gauge, and press the linear wire into an arc shape, and then place the wire. In the groove of the two curve gauges, the compression spring can be debugged or produced, which is time-consuming and laborious, greatly affects the production efficiency and reduces its own competitiveness. Therefore, the winding function of the large-diameter spring is bound to become a large-diameter compression spring manufacturing machine. Essential features. There are two main types of winding mechanisms currently on the market:

The mechanism is manually manual winding type, as shown in Figures 1 to 3, including the wire 5, the wire feeding wheel 6 and the front wire plate 8, the wire feeding wheel 6 sends the wire 5 through the front wire plate 8, and then the operator will The wire 5 is inserted into the hole at the end of the winding handle 13, and the wire handle 13 is manually rotated to wind the wire 5 into an arc shape, and then the wire 5 is placed in the groove of the two curve gauges 9, the curve The gauge 9 is placed on the curve gauge 12 and is adjusted by the slider 10. This method is difficult to operate, low in production efficiency, and difficult to promote.

The mechanism 2 is a mechanical winding type, as shown in FIGS. 4 to 6, including a wire 5, a wire feed pulley 6, a front wire guide 8, and a wire feed mechanism 6 sends the wire 5 through the front wire guide 8, the power mechanism 11 (hydraulic Cylinder or The motor acts to push the slider 10, and the curve gauge 9 on the curve gauge 12 acts on the wire 5 to press the wire 5 into an arc shape, and then place the wire 5 in the wire groove of the two curve gauges 9. The structure of this method is complicated, the operation is troublesome, and the cost is high and inefficient.

Summary of the invention:

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the deficiencies of the prior art and to provide a winding mechanism that enables the spring wire end to automatically rotate.

The invention is realized by the following technical solutions, comprising a plurality of pairs of wire feeding wheels arranged side by side on the machine body, wherein the symmetrically set wire feeding wheels rotate in the forward and reverse directions respectively to push the wire to move through the front wire plate to the sending port. A winding mechanism is further disposed on the body in front of the outlet of the wire material, and the winding mechanism includes a winding shaft that can be rotated by power, the winding wire is fixed on the winding shaft, and the pin is eccentrically mounted on the winding seat. The outer diameter of the pin shaft and the bobbin is slightly larger than the diameter of the wire, and the wire end of the wire extends between the bobbin and the pin.

The invention can make the compression spring machine become simple, easy, high-efficiency, low cost and suitable for promotion when debugging or producing springs and replacing large-diameter wires.

detailed description:

As shown in FIGS. 7 to 11, the present invention includes a plurality of pairs of wire feed wheels 6 which are arranged side by side on the machine body, and the symmetrically set wire feed wheels 6 are respectively rotated in the forward and reverse directions to push the wire 5 to move toward the discharge port through the front wire guide plate 8. . A winding mechanism is further disposed on the body in front of the outlet of the wire 5, and the winding mechanism includes a winding shaft 3 that can be rotated by power. The winding seat 4 is fixed on the winding shaft 3, and the pin 7 is eccentrically mounted on On the winding base 4, the outer diameter of the pin shaft 7 and the bobbin 3 is slightly larger than the diameter of the wire 5, and the wire end of the wire 5 extends between the bobbin 3 and the pin 7.

In operation, since the outer diameter of the pin shaft 7 and the bobbin 3 is slightly larger than the diameter of the wire 5, the wire feedr 6 feeds the wire 5 through the front wire guide 8, and the wire 5 enters the bobbin 3 and the pin shaft 7, Between the length of the wire 5 entering is sufficient for the arc deformation. The power system consisting of the motor 1 and the speed reducer 2 drives the bobbin 3 to rotate, and the bobbin 4 rotates following the bobbin 3, that is, the eccentrically mounted pin 7 rotates around the center of the bobbin 3, and the pin 7 and the winding The bobbin 3 locks the wire 5 in common, and the ends of the wire 5 are rotated together around the center of the bobbin 3 to cause arc deformation. When the bobbin 3 is rotated to the set position, the wire feed pulley 6 is fed, so that the wire 5 continues to move forward, and the wire 5 is no longer locked by the bobbin 3 and the pin 7, after the wire 5 is detached from the winding seat 4, The wire feeding wheel 6 is retracted, and the wire 5 is placed in the wire groove of the two curve gauges 9, and the curve gauge 9 is placed on the curve gauge seat 12, and is adjusted by the slider 10 to complete the winding step of the end.
