Abstract

The utility model relates to a combined die for an enamelled rectangular section conductor. The die comprises four base block components, wherein each base block component comprises a base block, a roller tube and an adjustable screw, the base block is in a bar shape, one end is connected with a connecting block, the other end is provided with an axial screw thread blind hole, a through hole is arranged on the connecting block, a spring slot is arranged on the connecting block outside the radial direction of the through hole, the adjustable screw is matched with the screw thread blind hole, the roller tube is in a tube shape, a screw is arranged outside the roller tube and is sleeved on the center of the base block, the connection mode of the four base block components is that: a roller tube of the base block a is inserted into a through hole of the connecting block of the base block b, the roller tube of the base block b is inserted into the through hole of the connecting block of the base block c, the roller tube of the base block c is inserted in the through hole of the connecting block of the base block c, the roller tube of the base block d is inserted in the through hole of the connecting block of the base block a, thereby forming a ring-shaped combined component, and the ring-shaped spring is coiled on the ring-shaped combined component. The combined die is used in producing lacquered wires with various specifications without replacing the die, thereby greatly reducing technique waste materials and guaranteeing that the surface quality of the enamelled rectangular section conductor is excellent.

Description

The enameled sheet wire assembling die

Technical field

The utility model belongs to the electromagnetic wire technical field of producing, is specifically related to the enameled sheet wire assembling die.

Background technology

Domestic traditional enameled sheet wire mode of production has two kinds at present, and a kind of is felt japanning method, and a kind of is fixed mould japanning method.The felt method is meant that encasing lenticular wire with felt is fixed on the felt folder, and the capillarity by felt is adsorbed on felt backing to lacquer, is coated onto the surface of lenticular wire.Though the japanning of felt method is simple, shortcoming is a lot: used lacquer contains relative with viscosity lower admittedly, and paint film just can be coated with evenly relatively like this, and the solvent height that this just causes in the lacquer has promptly improved cost, has polluted environment again; Felt is the meeting hardening after use a period of time, has influenced capillarity, and untimely replacing will have influence on the effect and the surface quality of products of japanning.The fixed die general laws is meant the die size for preparing per pass by the specification of lenticular wire earlier; after being contained in the per pass mould on the die frame; again in the past lenticular wire biography from mould together; lacquer is to be coated onto on the lenticular wire by the slit between mould and the lenticular wire; though the fixed die general laws requires the viscosity of lacquer and contains all admittedly to increase; surface quality also makes moderate progress; but very inconvenience of operation in the actual production; necessary shutdown operation when the production of thread-changing rule or certain road mould outlet problem; earlier line is cut off, again the new die cover is entered, then from new welding well line; could continue to produce, reduce rate of finished products and production efficiency.

Summary of the invention

For the production efficiency that improves the die methods enameled sheet wire, the quality of improving product, the utility model provides a kind of enameled sheet wire assembling die.

Concrete improvement technical scheme is as follows:

The enameled sheet wire assembling die comprises four matrix assemblies;

Each matrix assembly comprises matrix, roller and expansion screw; Described matrix is shaft-like, and an end is connecting contiguous block, and the other end is provided with the axial thread blind hole; Contiguous block is provided with the through hole of vertical and shaft, and the contiguous block of through hole radially outer is provided with spring groove; Described expansion screw and tapped blind hole are connected; Described roller is a tubulose, and its outside is a screw rod, is set in the matrix middle part;

If four matrix assemblies are respectively matrix assembly A, matrix assembly B, matrix assembly C and matrix assembly D;

In the through hole of the matrix b contiguous block that the roller place of the matrix a of matrix assembly A is plugged in, in the through hole of the matrix c contiguous block that the roller place of the matrix b of matrix assembly B is plugged in, in the through hole of the matrix d contiguous block that the roller place of the matrix c of matrix assembly C is plugged in, in the through hole of the matrix a contiguous block that the roller place of the matrix d of matrix assembly D is plugged in, form a ring-type sub-assembly; One ring spring is looped around on the ring-type sub-assembly.

Described ring spring is around the spring groove that is positioned at matrix a spring groove, matrix b spring groove, matrix c spring groove and matrix d.

Useful technique effect of the present utility model is, and is reasonable in design, simple in structure, easy to use; (when change in size is little) also mold exchange has more greatly reduced the generation of process residue when being used for the different size Production of Enamel Wires.On the other hand, the utility model can guarantee the surface quality excellence of enameled sheet wire, and online more mold exchange can not impact the quality of enamelled wire yet.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 3, enameled sheet wire comprises four matrix assemblies with assembling die;

Each matrix assembly comprises matrix, roller and expansion screw; Described matrix is shaft-like, and an end is connecting contiguous block, and the other end is provided with the axial thread blind hole; Offer the through hole of vertical and shaft on the contiguous block, offer spring groove on the contiguous block of through hole radially outer; Expansion screw and tapped blind hole are connected, see Fig. 1, expansion screw 3 is connected with the tapped blind hole of matrix 1, and expansion screw 6 is connected with the tapped blind hole of matrix 4, expansion screw 9 is connected with the tapped blind hole of matrix 7, and expansion screw 12 is connected with the tapped blind hole of matrix 10; Described roller is a tubulose, and its outside is a screw rod, is sleeved on the matrix middle part.

Referring to Fig. 1, in the through hole of matrix 4 contiguous blocks that the roller 2 of the matrix 1 of matrix assembly A is inserted into, in the through hole of matrix 7 contiguous blocks that the roller 5 of the matrix 4 of matrix assembly B is inserted into, in the through hole of matrix 10 contiguous blocks that the roller 8 of the matrix 7 of matrix assembly C is inserted into, in the through hole of matrix 1 contiguous block that the roller 11 of the matrix 10 of matrix assembly D is inserted into, form a ring-type sub-assembly.As seen from Figure 2, a ring spring 13 is looped around on the ring-type sub-assembly, and promptly ring spring 13 is around the spring groove that is positioned at matrix 1 spring groove, matrix 4 spring grooves, matrix 7 spring grooves and matrix 10.

During use, processed lenticular wire 14 is positioned at ring-type sub-assembly middle part, is used for four R angle japannings of lenticular wire 14; By adjusting the length of spring 13, regulate the tensile force between mould and the lenticular wire 14, mould can be slided on line freely, guarantee that lacquer can be coated on the lenticular wire 14 uniformly.
