Description

The fabricating tools of cloud type torsionspring

Technical field

The fabricating tools that the present invention relates to a kind of cloud type torsionspring, belongs to field of machining.

Background technology

As shown in Figure 1, cloud type torsionspring complex contour dimensional requirement is higher, generally makes to be now wound around by hand processing, and spring spiral size and profile can not be guaranteed; Use spring Coil-up machined, but the equipment tool setting time is long, initial investment expense is large, and needs frequent tool setting guarantee part product requirement, and tool wear is serious, causes cost of goods manufactured to strengthen.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of fabricating tools of cloud type torsionspring, and this frock volume is little, simple in structure, be applicable to one man operation, not only safe and reliable, production efficiency is high simultaneously, and the product shape processing is attractive in appearance, each size conforms designing requirement.

For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of fabricating tools of cloud type torsionspring, two parallel pieces that fix to clamp are set at the vertical plane middle part of L-type tool body, two centres that fix to clamp piece, slip clamp is set, the screw portion of swivel bolt is connected with slip clamp through tool body; Below the vertical plane of tool body, be provided with cushion block, the outer surface center of cushion block is connected with the one end of winning in succession, and the other end of winning in succession inserts and is wound around axle, is wound around the outer distolateral connection pivoted arm of axle, the other end connecting handle of pivoted arm is provided with spring I on the winding axle at pivoted arm and between winning in succession simultaneously; On the both sides that fix to clamp piece, be respectively equipped with die head, die head is provided with helicla flute, at the inner termination place that is wound around axle, is provided with limiting plate, the side surface of limiting plate and the laminating of the excircle of die head.

Described die head is threaded with the vertical plane of tool body, behind the back side of the tail end extending tool main body of die head, be connected with two connecting rods respectively, the top of one of them connecting rod is provided with depression bar, two connecting rods are connected with one end of spring II after connecting by connecting plate, and the other end of spring II is connected with the back side of tool body.

The fabricating tools of this cloud type torsionspring has adopted the structure that fixes to clamp piece and slip clamp to be fixed spring steel wire, utilizes winding axle upper limit plate to carry out the winding of cloud type to steel wire, therefore make the winding of spring convenient simultaneously.

Utilize spring and the bar linkage structure of instrument backboard, when connecting rod is pulled, die head reversion, exits the cloud type torsionspring processing, and waits for processing next time.

The specific embodiment

As shown in Figures 2 to 4, a kind of fabricating tools of cloud type torsionspring, two parallel pieces 4 that fix to clamp are set at the vertical plane middle part of L-type tool body 9, two centres that fix to clamp piece 4, slip clamp 15 is set, the screw portion of swivel bolt 11 is connected with slip clamp 15 through tool body 9; Below the vertical plane of tool body 9, be provided with cushion block 6, the outer surface center of cushion block 6 is connected with 10 the one end of winning in succession, 10 the other end of winning in succession inserts and is wound around axle 17, be wound around the outer distolateral connection pivoted arm 2 of axle 17, the other end connecting handle 1 of pivoted arm 2 is simultaneously provided with spring I 18 on pivoted arm 2 and the winding axle 17 of winning in succession between 10; On the both sides that fix to clamp piece 4, be respectively equipped with die head 3, die head 3 is provided with helicla flute, at the inner termination place that is wound around axle 17, is provided with limiting plate, the excircle laminating of the side surface of limiting plate and die head 3.

Described die head 3 is threaded with the vertical plane of tool body 9, behind the back side of the tail end extending tool main body 9 of die head 3, be connected with two connecting rods 7 respectively, the top of one of them connecting rod 7 is provided with depression bar 8, two connecting rods 7 are connected with one end of spring II 14 after connecting by connecting plate 13, and the other end of spring II 14 is connected with the back side of tool body 9.

Its concrete operating procedure is as follows:

1) operator is placed on tool body 9 on bench vice and clamps, and spiral bolt 11 is loosening downwards, is slip clamp 15 and fixes to clamp between piece 4 and reserve gap, and make the end limiting plate that is wound around axle 17 in leaving the initial position of die head 3; Spring steel wire is placed on to slip clamp 15 and fixes to clamp in the gap between piece 4, and tighten swivel bolt 11 promotion slip clamps 15 by steel wire clamping, now, steel wire is just in time fitted with two die heads, 3 positions;

2) during processed springs, first process the spring at die head place, the left side, utilize handle 1 to drive pivoted arm 2 rotations, make to be wound around limiting plate and spring steel wire laminating on axle 17, turning handle 1 makes spring steel wire be wound around along the helicla flute rising of die head 3, during winding, to guarantee that spring steel wire all the time in helicla flute, must not come off;

3), after the spring manufacture at the die head place in left side completes, release handle 1, is wound around axle and returns to initial position under the effect of spring I 18, makes limiting plate leave spring steel wire; Then move and win 10 in succession, the die head top that the limiting plate being wound around on axle 17 is moved to right, the operation of repeating step 2, completes the spring processing at die head place, right side;

4) unclamp swivel bolt 11 after machining, trip spring steel wire, then according to the contrary direction of die head spiral, pull depression bar 8, the acting in conjunction die head by two connecting rods rotates to the direction contrary with winding direction, and the cloud type torsionspring processing exits die head; Unclamp depression bar, under the effect of spring II 14, get back to initial position, wait for the processing of next part part.
