Description

Multi-angle self-rotating paint-wrapping die for flat electromagnetic wire

Technical Field

The utility model relates to the technical field of enameled wire cable processing, in particular to a paint-wrapping die for a multi-angle self-rotating flat electromagnetic wire.

Background

Enamelled wire is a common wire material consisting of a metallic conductor surrounded by an insulating layer (usually coated with an insulating varnish). The name of such wires is derived from the fact that their insulation layers usually use enamels as insulation material.

In the production process of a traditional flat enamelled wire (the section of a copper wire in a cable is rectangular), a general lacquered die is fixed, and a phenomenon that a more or less central line is inconsistent is caused due to the fact that a bare wire is twisted or the transmission direction is deviated in the transmission process, so that the quality of the enamelled wire is affected.

To solve this problem, the chinese patent with the grant publication number CN217280244U discloses a self-rotating flat electromagnetic wire enameling mold, which adapts to the transmission direction of bare wires through a thrust bearing with a split structure, and the principle is as follows: in the continuous transmission enamelling process of the bare wire, upward force is applied to the die body and the thrust ball bearing, the upper side seat ring of the thrust ball bearing is abutted against the first die frame, the lower side seat ring of the thrust ball bearing is abutted against the supporting piece, and the rotation of the lower side seat ring is utilized to drive the die body to rotate together, so that the outlet direction of the die body is adapted to the transmission direction of the bare wire (namely, the rotation and the offset of the bare wire), and the uniformity of enamelling of the bare wire is improved. Meanwhile, the published die frame structure can show that the die body can also longitudinally deflect along the opening directions of the first through groove and the second through groove so as to adapt to the change of the longitudinal transmission direction deflection of the bare wire.

However, some problems are solved when the paint coating die is used, in actual production, the problems of installation precision of each part of a machine, arrangement position of equipment and the like can cause that a flat copper wire not only generates rotary deviation and longitudinal deviation, but also generates transverse deviation or rotary transverse deviation, when transverse deviation or rotary transverse deviation occurs, the flat copper wire cannot drive a die body to make adaptive transverse deviation movement due to the limitation of the transverse widths of a first through groove and a second through groove, the conventional paint coating die cannot perform multi-angle adaptation adjustment, and a phenomenon of paint film eccentricity easily occurs, so that the quality of enameled wires is influenced, and therefore the paint coating die for the multi-angle self-rotating flat electromagnetic wire is provided to meet requirements.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples: referring to fig. 1-3, the multi-angle self-rotating flat electromagnetic wire paint packing mold comprises a mold 2, a mold frame 1 and a thrust bearing 4, wherein a supporting ring 3 is installed on the outer wall of the mold 2, the mold frame 1 is matched with the mold 2, the thrust bearing 4 is sleeved on the mold 2, the thrust bearing 4 comprises an upper seat ring, a lower seat ring and a ball retainer provided with balls, a C-shaped installation cavity 6 and a rectangular installation cavity 5 are arranged on the mold frame 1 up and down, the width of the rectangular installation cavity 5 is larger than the diameter of the mold 2 and smaller than the diameter of the lower seat ring of the thrust bearing 4, the maximum X-axis linear length and the maximum Y-axis linear length of the C-shaped installation cavity 6 are both larger than the diameter of the mold 2, and the maximum X-axis linear length of the C-shaped installation cavity 6 is smaller than the diameter of the upper seat ring.

When the flat copper wire is used, the upper end of the die 2 is inserted into the C-shaped mounting cavity 6, the flat copper wire passes through the die 2, when transverse offset or rotary transverse offset occurs, as the width of the rectangular mounting cavity 5 is larger than the diameter of the die 2, and the maximum X-axis linear length and the maximum Y-axis linear length of the C-shaped mounting cavity 6 are both larger than the diameter of the die 2 (which reserves a large enough space for the movement of the bare wire), the upper end of the die 2 can be driven to perform transverse offset movement or simultaneous adaptive movement of transverse 2 offset and rotary offset in the C-shaped mounting cavity 6 under the action of tensile force generated when the bare wire is transmitted, the lower end of the die 2 can perform longitudinal or rotary adaptive movement in the rectangular mounting cavity 5, and simultaneously the lower end of the die 2 can perform multi-angle adaptive movement in the rectangular mounting cavity 5, and the upper end of the die 2 of the enamelling paint can also perform multi-angle adaptive movement in the rectangular mounting cavity 6, and the lower end of the bare wire can also perform multi-angle adaptive movement in the rectangular mounting cavity 5.

It should be noted that: firstly, in the actual production process, the transverse offset distance of the bare wire is often larger than the longitudinal offset distance, so that a C-shaped mounting cavity 6 with the linear distance along the X axis larger than the linear distance along the Y axis is arranged on the die carrier; and secondly, the transverse direction increased in the above is the X-axis direction, and the longitudinal direction is the Y-axis direction.

As a preferred implementation of this embodiment, as shown in fig. 2, the mold further includes an open cavity 9, the open cavity 9 is in a size consistent with the opening of the C-shaped mounting cavity 6, the width of the open cavity 9 is smaller than the diameter of the mold 2, and the open cavity 9 can form a barrier for the mold 2, so that the mold 2 is prevented from being pulled in the horizontal direction to move out of the C-shaped mounting cavity 6.

When the upper end of the die 2 is longitudinally or transversely shifted (due to oblique pulling force on the die 2) in the C-shaped mounting cavity to cause the die 2 to be in an inclined state as a whole (the lateral and longitudinal distances of the C-shaped mounting cavity are deviated from the lateral and longitudinal distances of the rectangular mounting cavity 5), and the upper end of the upper race of the inclined thrust bearing is locally contacted with the die carrier 1 due to the pulling force during bare wire transportation, the force is locally concentrated in one part, so that the balls stressed in the ball retainer are subjected to extremely high pressure, and other balls are subjected to extremely low pressure or no pressure, and the surface of the balls may be damaged, pressed or cracked. This can reduce the intensity and the life-span of ball to probably arouse the problem that the roll is unsmooth or the ball is damaged, influence thrust bearing's life, so set up annular gasbag 7 and collar 8, when thrust bearing 4's one end pressurized, with the annular gasbag 7 position of pressurized end homonymy receive the extrusion, annular gasbag 7 position relative with the pressurized end will outwards take place to expand, thereby jack up each part one end upwards, make each part in close contact simultaneously make the up end of upper race and die carrier 1 contact completely, make each power share on each ball, avoid the ball to receive too big pressure effect, improve thrust bearing's life.

It should be noted that, firstly, due to the reasons of processing precision and convenience for subsequent installation, the sleeve holes arranged at the axes of the components of the existing thrust bearing 4 are all larger than the outer diameter of the die 2 by 0.4-0.8 mm, so that when the die 2 is in an inclined state and is partially pressed, gaps are reserved between the non-pressed ends of the components, and the pressed ends of the components are tightly contacted, so that excessive force acts on the pressed balls to reduce the service life of the thrust bearing; secondly, the annular air bag 7 can be fixed with the mounting ring 8 and the lower seat ring respectively, so that the annular air bag 7 is prevented from being contacted with other objects and generating relative friction to cause abrasion, and the influence on the service life of the annular air bag 7 is avoided.
