Description

A kind of automatic spring wind-

Technical field

The utility model 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 carry out the repeatedly bending of different angles, different directions and different radius bend to the silk thread of different-diameter with spring coiling machine.

Spring coiling machine of the prior art comprises frame and is successively set on wire agency, wind spring mechanism and the commentaries on classics line mechanism on the frame that 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 complete machine structure complicated, in addition, change between line mechanism and the line sending case through band transmission synchronously; Synchronous band has been used of a specified duration and has been had relaxation, influence transmission accuracy.

The utility model content

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

The utility model solves the technical scheme that its technical problem adopted: a kind of automatic spring wind-; Comprise frame and be successively set on wire agency, wind spring mechanism and the commentaries on classics line mechanism on the frame; Wire agency comprises guide roller, is located at the line sending case at guide roller rear and is 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, and are equipped with the wind spring drive motors on each knife rest; The wind spring drive motors has been electrically connected micro computer with commentaries on classics line drive motors, changes between line drive motors and the main shaft to connect through 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 beneficial effect of the utility model is: eight knife rests are driven respectively by eight wind spring drive motors; Omitted cam; Change and pass through the gear train connection between line drive motors and the main shaft, can keep precision for a long time, the wind spring drive motors is controlled separately by micro computer with commentaries on classics line drive motors; Complete machine structure becomes simply, and production efficiency is improved.

Description of drawings

Fig. 1 is the structural representation of the utility model master apparent direction;

Fig. 2 is the structural representation of the right apparent direction of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

With reference to Fig. 1, shown in Figure 2; A kind of automatic spring wind-comprises frame 1 and is successively set on wire agency, wind spring mechanism and the commentaries on classics line mechanism on the frame 1 that wire agency comprises guide roller 21, is located at the line sending case 22 at guide roller 21 rears and is 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, and are equipped with wind spring drive motors 32 on each knife rest 33, and wind spring drive motors 32 has been electrically connected micro computer with commentaries on classics line drive motors 4; Described commentaries on classics line drive motors 4 is servomotor with wind spring drive motors 32; Change between line drive motors 4 and the main shaft 24 and connect through gear train 5, wherein, described gear train 5 is made up of intermeshing first gear 51, second gear 52, the 3rd gear 53 and the 4th gear 54.

During the utility model work, tinsel gets into line sending case 22 via guide roller 21, pushes ahead to panel 31 the place aheads through Wire Wheel 23 then; Shaping and cutting-out by eight different cutters 34 completion springs on the knife rest 33; Realize the upset of silk thread through changeing scrolling that line drive motors 4 drives line sending casees 22,, omitted cam because eight knife rests 33 are driven respectively by eight wind spring drive motors 32; Change between line drive motors 4 and the main shaft 24 and connect through gear train 5; Can keep precision for a long time, wind spring drive motors 32 with 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 different shape complicated spring and steel wire goods.

The foregoing description is the principle and the effect thereof of illustrative the utility model 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 utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
