Abstract

The invention discloses an automatic spring coiling machine. The machine comprises a frame, a wire feeding mechanism, a spring coiling mechanism and a wire turning mechanism, wherein the wire feeding mechanism comprises a wire guiding wheel, a wire feeding box which is arranged behind the wire guiding wheel, and a plurality of wire feeding wheels which are arranged on the wire feeding box; the wire feeding box is fixedly provided with a horizontal spindle; the spring coiling mechanism comprises a round panel which is arranged behind the wire feeding box, and eight tool rests which are uniformly arranged on the panel; each tool rest is provided with a tool; the wire turning mechanism comprises a wire turning driving motor which is arranged below the wire feeding box and is connected with the spindle; the eight tools have different specifications; each tool rest is provided with a spring coiling driving motor; the spring coiling driving motors and the wire turning driving motor are electrically connected with a microcomputer; and the wire turning driving motor is connected with the spindle through a gear group. A cam is eliminated, the wire turning driving motor is connected with the spindle through the gear group, and the spring coiling driving motors and the wire turning driving motor are independently controlled by the microcomputer, so that the structure of the whole machine is simple, and production efficiency is improved.

Description

A kind of automatic spring wind-

Technical field

The present invention relates to the metal wire rod process equipment, particularly a kind of multiaxis universal type spring coiling machine.

Background technology

In metal wire rod processing, often need the silk thread of different-diameter to be carried out the repeatedly bending of different angles, different directions and different radius bend with spring coiling machine.

Spring coiling machine of the prior art, comprise frame and be successively set on wire agency on the frame, wind spring mechanism and change line mechanism, wherein wind spring mechanism comprises circular panel and evenly is located at eight knife rests on the panel, cutter all is installed on each knife rest, behind each knife rest all by a cam, by eight cams of a driven by motor, need in the use respectively each cam to be adjusted, cause the complete machine structure complexity, in addition, change and pass through band transmission synchronously between line mechanism and the line sending case, synchronous band has been used of a specified duration and has been had relaxation, influence transmission accuracy.

Summary of the invention

For overcoming the deficiencies in the prior art, the invention provides the automatic spring wind-that a kind of simple in structure, precision improves.

The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic spring wind-, comprise frame and be successively set on wire agency on the frame, wind spring mechanism and commentaries on classics line mechanism, wire agency comprises guide roller, be located at the line sending case at guide roller rear and be installed in a plurality of Wire Wheels on the line sending case, be fixed with on the line sending case level to main shaft, wind spring mechanism comprises the round panel of being located at line sending case rear and evenly is located at eight knife rests on the panel, cutter all is installed on each knife rest, change line mechanism and comprise the commentaries on classics line drive motors of being located at line sending case below and being connected with main shaft, described eight tool specifications have nothing in common with each other, be equipped with the wind spring drive motors on each knife rest, wind spring drive motors and commentaries on classics line drive motors have been electrically connected micro computer, change between line drive motors and the main shaft to connect by gear train.

Wherein, described gear train is made up of intermeshing first gear, second gear, the 3rd gear and the 4th gear.

In addition, described commentaries on classics line drive motors and wind spring drive motors are servomotor.

The invention has the beneficial effects as follows: eight knife rests are driven respectively by eight wind spring drive motors, omitted cam, change between line drive motors and the main shaft and connect by gear train, can keep precision for a long time, wind spring drive motors and commentaries on classics line drive motors are controlled separately by micro computer, complete machine structure becomes simply, and production efficiency is improved.

Description of drawings

Fig. 1 is the structural representation of master's apparent direction of the present invention;

Fig. 2 is the structural representation of the right apparent direction of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

With reference to Fig. 1, shown in Figure 2, a kind of automatic spring wind-, comprise frame 1 and be successively set on wire agency on the frame 1, wind spring mechanism and commentaries on classics line mechanism, wire agency comprises guide roller 21, be located at the line sending case 22 at guide roller 21 rears and be installed in a plurality of Wire Wheels 23 on the line sending case 22, Wire Wheel 23 is by driven by servomotor, be fixed with on the line sending case 22 level to main shaft 24, wind spring mechanism comprises the round panel 31 of being located at line sending case 22 rears and evenly is located at eight knife rests 33 on the panel 31, on each knife rest 33 cutter 34 is installed all, change line mechanism and comprise the commentaries on classics line drive motors 4 of being located at line sending case 22 belows and being connected with main shaft 24, described eight cutter 34 specifications have nothing in common with each other, be equipped with wind spring drive motors 32 on each knife rest 33, wind spring drive motors 32 and commentaries on classics line drive motors 4 have been electrically connected micro computer, described commentaries on classics line drive motors 4 and wind spring drive motors 32 are servomotor, change between line drive motors 4 and the main shaft 24 and connect by gear train 5, wherein, described gear train 5 is by intermeshing first gear 51, second gear 52, the 3rd gear 53 and the 4th gear 54 are formed.

When the present invention works, tinsel enters line sending case 22 via guide roller 21, push ahead to panel 31 the place aheads by Wire Wheel 23 then, finish the shaping and the cutting-out of spring by eight different cutters 34 on the knife rest 33, realize the upset of silk thread by the scrolling that changes line drive motors 4 drive line sending casees 22, because eight knife rests 33 are driven respectively by eight wind spring drive motors 32, omitted cam, change between line drive motors 4 and the main shaft 24 and connect by gear train 5, can keep precision for a long time, wind spring drive motors 32 and change line drive motors 4 and control separately by micro computer, it is simple that complete machine structure becomes, production efficiency is improved, and this machine can roll the spring and the steel wire goods of different shape complexity.

The foregoing description is illustrative principle of the present invention and effect thereof only; and the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
