Abstract
The utility model discloses a convenient usage transformer winding wire transposition wrench which is convenient for using, which comprises a wrench main body (1), two screws (2), and a wrench handle (3), wherein, the screw is not completely provided with screw thread, one end close to the screw cap is a smooth circular shaft, the corresponding end of the screw cap is a screw thread shaft. When wires are bended, the smooth circular shaft directly contacts the wires to ensure the wires not to be damaged, and the height between the screw cap and wrench can be adjusted conveniently through rotating the screw, which fits the different specification of the wires, and the utility model has the advantage of convenient use.
Description
The disclosed Transformer Winding wire transposition of the utility model spanner belongs to transformer and makes the tooling device field.
At present the transformer coil winding mode that adopts of transformer manufacturing has laminar and cake formula, and wherein laminar is divided into drum type brake and paper tinsel formula again, and the cake formula is divided into continous way again, is entangled with formula, internally shielded, spiral and alternating expression.In the drum type brake and disc coil of multi-thread coiling in parallel; for each root lead final lengths is equated; and make the residing stray field of each root lead position close as far as possible; reach the purpose that reduces the coil inside circulation loss; this just must make each lead along the radial transposition of winding on assigned position by design; it is curved with the transposition spanner each root lead to be bent into serpentine in different intervals, and that guarantees to replace carries out smoothly.In addition, adopt the solid conductor coiling, around an intact cake during to next cake transition, its changeover portion must be bent into serpentine and bend, and also must bend with the transposition spanner at lead.
Traditional transposition spanner is made up of wrench body, handle and two adjusting screw(rod)s.Two or more screws that having on body keeps at a certain distance away is arranged in order, two adjusting screw(rod)s are full thread, are installed in respectively in the corresponding screw.When bending serpentine to lead when curved, two screw rods are stuck in the both sides of lead, as shown in Figure 1, pull handle according to certain orientation and can finish the process of bending.Lead plays waveform when preventing to bend, and needs rotary screw, and the adjusting screw(rod) height makes spiro rod cap that lead is pressed on the wrench body.
Because in the process of bending, lead directly contacts with transposition spanner screw rod, the screw thread on the screw rod stays impression easily on lead, perhaps cause the damage of wire insulation, and the electric property of lead will descend to some extent.
Screw thread is hindered line when avoiding operating, and traditional solution has two kinds, and the one, the sleeve pipe of a smooth in appearance of cover makes the sleeve pipe of smooth in appearance contact with lead on screw rod, comes guardwire with this.But the height of sleeve pipe should be consistent with the thickness of current operation lower wire, lead can be pressed on the wrench body with the cap that guarantees screw rod, when the lead of giving another specification bends " S " when curved, more casing replacing makes the sleeve pipe height be fit to the thickness of this specification lead.
Another kind of solution is to twine strap on screw rod, and is identical with first kind of solution, when operated wire gauge changes, just needs strap is removed, and twines again again.
But more than the equal guardwires of two kinds of methods, but when the lead of giving multiple different wire gauges is operated, need frequently more casing replacing or twine strap, troublesome poeration.The purpose of this utility model is to provide a kind of Transformer Winding wire transposition spanner of neither hindering line, again need not any auxiliary equipment just can regulate with conductor thickness fast.
The transposition spanner that the utility model is described is made up of wrench body, handle, two screw rods, is being arranged in order two or more screws on wrench body, and two screw rods are installed in respectively in the corresponding screw.Screw rod is non-full thread, and there is the spiro rod cap of a circle on the top of screw rod, and the part that is right after with spiro rod cap is the smooth round bar that does not have screw thread, and the end that spiro rod cap is relative is a threaded rod; Screw is made up of two different parts of hole face structure, and the hole face of corresponding smooth round bar part is smooth, and the screw thread that partly matches with screw flight is arranged at the screw bottom.
The transposition spanner of the utility model design polished rod when bending line directly contacts with lead, guarantees not hinder lead.When wire gauge changes simultaneously, can assign to the adjusting screw(rod) cap to the height between wrench body by the threaded portion, to block the lead of different-thickness.
Fig. 1, transposition spanner bend the curved schematic diagram of serpentine;
Fig. 2, transposition spanner structure figure of the present utility model;
A screw rod of Fig. 3, the utility model transposition spanner.
With reference to the accompanying drawings the utility model is further specified below.
As shown in Figure 2, the utility model comprises wrench body (1), two screw rods (2) and pinch bar (3) composition.In the utility model, two screw rods play the role of positioning.Two or more screws are arranged on wrench body, and two screw rods are installed in the suitable screw.Owing to bending serpentine when curved, distance between two screw rods has determined the curved size of serpentine that bent, when screw number during more than two, screw rod can be installed in the size that just can regulate distance between two screw rods on the suitable position, hole, can bend the different serpentine of size and bend.
Be illustrated in figure 3 as a screw rod of the present utility model.One end of screw rod has a cap (4), and the part that is connected with spiro rod cap is the smooth round bar (5) that does not have screw thread, and an end relative with spiro rod cap is threaded rod (5).The design of screw and the design of screw rod match, and are the screw thread that matches with threaded rod (5) in the bottom of screw, and the screw oral area is the smooth circular hole of hole face.The effect of threaded rod (5) has two, and the first, threaded rod is fixed in the screw; The second, the effect of lifting screw rod can be clamped on lead on the wrench body spiro rod cap.For guaranteeing that in the process of bending always the smooth round bar part of screw rod contacts with lead, the height of smooth round bar part should be slightly larger than the maximum ga(u)ge of the required lead that bends.When bending the less lead of thickness, smooth round bar will enter the smooth part of screw hole face.
The utility model is easy to use, for example bending wire gauge when being the lead of 2.81*5.75, if with tradition transposition spanner, and adopt sleeve pipe to avoid damage wires, needing at cover on the screw rod highly is sleeve pipe about 3mm, bend wire gauge again when being the lead of 6.0*15.15, then need screw rod is backed out, remove original sleeve pipe, replacing highly is the sleeve pipe about 6mm, again screw rod is screwed on, operated time-consuming.As just having economized this part time with the new construction spanner, it is very convenient to operate.
