Description

Technical Field

[0001] The present invention relates to the technical field of winding, and more particularly to a winding die for a random winding. Background Art

[0002] At present, there are basically two methods for winding loose windings: (1) using a dedicated integral winding die for winding. The winding die is a whole-plate design and can only be used for winding products of the same size. (2) using a split winding die for winding. The two ends of the winding die are separate modules. When used in conjunction with a dedicated winding bracket, the length of the straight side of the winding can be adjusted. Both of these winding methods require the winding die to be newly manufactured or modified according to product requirements in order to meet the winding requirements of loose windings. The main disadvantages are that the number of dies is large, the cost is high, and the versatility of the dies is relatively poor. For a multi-variety small-batch production model, the use range and frequency of a single winding die are small, and frequent mold searches and mold changes result in a waste of time and cost.

[0003] In summary, how to effectively solve the problem of inconvenient winding in the prior art is a problem that those skilled in the art urgently need to solve. Summary of the Invention

[0023] The embodiment of the present invention discloses a random winding die, which effectively solves the problem of inconvenient winding in the prior art.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 3 , Figure 1 A schematic structural diagram of a random winding die provided in an embodiment of the present invention; Figure 2 A schematic structural diagram of a winding module provided in an embodiment of the present invention; Figure 3 A schematic side structural diagram of a winding module provided in an embodiment of the present invention.

[0026] In a specific embodiment, this embodiment provides a random winding die for use on a winding machine for winding. Specifically, the random winding die includes an end winding die, a first straight edge winding die, and a second straight edge winding die. To facilitate the description of its structure, two directions are set, namely a first direction and a second direction, wherein the first direction and the second direction are arranged perpendicular to each other. In actual application, the first direction is the extension direction of the straight edge of the winding coil, which is also referred to as the length direction hereinafter; and the second direction is the width direction of the winding coil, which is referred to as the span direction hereinafter.

[0027] The first straight-line winding module and the second straight-line winding module are arranged side by side along the first direction and the distance between them is adjustable in the first direction, so that the spacing between the first straight-line winding module and the second straight-line winding module in the first direction can be changed, thereby changing the length of the straight side of the winding coil. It should be noted that the adjustable distance means that the distance between the two can be changed, and after the change, the adjustment can be stopped, such as by locking, fixing, etc. to prevent further change, so that it can be stably maintained at the current changed position, and the distance is adjustable in the first direction or the distance is adjustable in the second direction, that is, the distance is adjustable in one direction, which means that the change in the distance between the two is a change in that direction.

[0028] Among them, the end winding module includes two end winding modules 1 arranged in opposite directions along the first direction, and the distances of the two end winding modules 1 of the end winding module in the first direction are adjustable relative to the first straight-line winding module. Because they are adjustable relative to the first straight-line winding module 2, the distance between the two end winding modules 1 in the first direction is also adjustable, and the length of the winding coil can be changed by adjusting the distance between the two end winding modules 1 in the first direction. The distances of the winding modules in the first direction relative to the first straight-line winding module are adjustable, and the distance between the end in the length direction of the winding coil and the end in the straight-line direction of the winding coil can be changed. It should be noted that being arranged in opposite directions means that the bearing surfaces are arranged far away from each other. For example, when winding, the two ends in the length direction of the winding coil are respectively against the sides of the two end winding modules 1 that are far away from each other.

[0029] The first straight-line winding module and the second straight-line winding module correspond to the two ends of the straight-line side of the winding coil, respectively. The first straight-line winding module includes two first straight-line winding modules 2, and the two first straight-line winding modules 2 are arranged opposite to each other along the second direction and the distance between them in the second direction is adjustable. The second straight-line winding module includes two second straight-line winding modules 3, and the two second straight-line winding modules 3 are arranged opposite to each other along the second direction and the distance between them is adjustable in the second direction. The first straight-line winding module 2 and the second straight-line winding module 3 located on the same side correspond to the two ends of the same straight-line side of the winding coil, respectively.

[0030] When winding, one winding method is as follows: the winding passes through the end winding module 1 at one end, the first straight line winding module 2 on one side, the second straight line winding module 3 on one side, the end winding module 1 at the other end, the second straight line winding module 3 on the other side, and the first straight line winding module 2 on the other side, and so on in sequence to form a winding coil.

[0031] In the random winding winding mold, when in use, the spacing between the two end winding modules 1 on the end winding module is adjusted according to the required winding coil length, and the spacing between the end winding modules 1 at the opposite ends of the first straight side winding module and the second straight side winding module is adjusted according to the bending degree of the end and the straight side length requirement. Then, according to the span requirement, the spacing between the two first straight side winding modules 2 and the spacing between the two second straight side winding modules 3 are adjusted, thereby achieving the spacing adjustment between the six winding modules in the first direction and the second direction, so as to fully meet the needs of winding coils of various sizes. In the random winding winding mold, the end winding module, the first straight side winding module and the second straight side winding module are provided, which can achieve the adjustment of the straight side length, the overall length, the end length and the span, and can be applied to a large number of winding operations of different sizes. In summary, the random winding winding mold can effectively solve the problem of inconvenient winding in the prior art.

[0032] As mentioned above, the modules and the modules are adjustable. Specifically, how to achieve the adjustment between the two structures can be achieved by clamping or removable bolts with multiple mounting positions at a certain point of the connecting hub between the two. In order to better achieve the adjustability and facilitate the adjustment, it is preferred that at least one distance adjustment is achieved through a long strip slide hole 7 and a matching locking screw 8. For example, two components are respectively connected to two components with adjustable distances. One of the two components is provided with a locking screw 8 and the other is provided with a long strip slide hole 7. When the locking screw 8 is tightened, the cap or nut abuts against one side of the long strip slide hole 7 to push the two components closer. In order to facilitate the control of the distance between the adjustments, it is preferred that a scale is provided on the corresponding edge of the long strip slide hole 7 so that the adjustment distance can be determined as quickly as possible through the scale.

[0033] Specifically, in order to set up a long strip sliding hole 7 to facilitate adjustable connection, it is preferred here that the end winding module includes a length winding arm 4 extending along the first direction, the first straight side winding module includes a first span winding arm 5 extending along the second direction, and the second straight side winding module includes a second span winding arm 6 extending along the second direction. The length winding arm 4, the first span winding arm 5 and the second span winding arm 6 are all provided with a long strip sliding hole 7.

[0034] Correspondingly, the locking screw 8 fixed at the end of the end winding module 1 can be inserted into the long strip sliding hole 7 of the length winding arm 4 and locked by a nut. If the end winding module 1 is provided with a screw, it can be a screw fixed to the winding module or a long bolt passing through the winding module, which serves as the locking screw 8. The locking screw 8 passes through the long strip sliding hole of the length winding arm 4, and then the nut is screwed on until the nut and the end winding module 1 clamp the length winding arm 4. Correspondingly, the locking screw 8 fixed at the end of the first straight edge winding module 2 can be inserted into the long strip sliding hole 7 of the first span winding arm 5 and locked by a nut. Correspondingly, the locking screw 8 fixed at the end of the second straight edge winding module 3 can be inserted into the long strip sliding hole 7 of the second span winding arm 6 and locked by a nut.

[0035] Correspondingly, it is preferred that the first span winding arm 5 and the length winding arm 4 are connected by the locking screw 8 passing through the elongated sliding hole 7 of the length winding arm 4, or by the locking screw 8 passing through the elongated sliding hole 7 of the first span winding arm 5; the second span winding arm 6 and the length winding arm 4 are connected by the locking screw 8 passing through the elongated sliding hole 7 of the length winding arm 4, or by the locking screw 8 passing through the elongated sliding hole 7 of the second span winding arm 6. In a preferred embodiment, a locking screw 8 can be fixed on the length winding arm 4, or a locking screw 8 can be passed through the circular through-hole on the length winding arm 4, the locking screw 8 passes through the elongated sliding hole 7 of the first span winding arm 5, and is locked by a nut, so as to achieve adjustment between the first span winding arm 5 and the length winding arm 4 in the second direction. Of course, the first span winding arm and the length winding arm 4 can also be fixedly connected so that no adjustment is required between the two. For example, a locking screw 8 can be fixed on the second span winding arm 6, passing through the length winding arm 4 and locked by a nut.

[0036] Furthermore, in order to facilitate the fixing of the entire random winding die on the winding machine, it is preferred that two back baffles 9 are arranged in parallel along the second direction and are respectively arranged at one end of the two first straight-line winding modules 2. The back baffle 9 has an elongated sliding hole 7 extending along the first direction; the two ends of the elongated sliding hole 7 of the back baffle 9 are respectively penetrated by the locking screws 8 at the end of the first straight-line winding module 2 and the end of the second straight-line winding module 3 located on the same side in the second direction, and are both locked by nuts. The back baffle 9 is used to be fixed on the mounting flange of the winding machine. The locking screw 8 at one end of the first straight-line winding module 2 can simultaneously pass through the first span winding arm 5 and the corresponding back baffle 9, and then be locked with a nut; correspondingly, the locking screw 8 at one end of the second straight-line winding module 3 can simultaneously pass through the second span winding arm 6 and the corresponding back baffle 9, and then be locked with a nut.

[0037] To better secure the winding modules, it is preferred that both ends of the end winding module 1 be equipped with length winding arms 4; both ends of the first straight-line winding module 2 be equipped with first-span winding arms 5; and both ends of the second straight-line winding module 3 be equipped with second-span winding arms 6. The aforementioned back baffle 9 is only required at one end of the first straight-line winding module 2, eliminating the need for repeated installations. Each winding module is threaded with a long screw, with locking screws 8 at each end of the long screw, which are exposed at each end of the winding module. After passing through the corresponding winding arms, each end is locked with a nut.

[0038] Furthermore, in order to better carry out winding, a plurality of winding grooves 10 are correspondingly provided on the outer sides of the end winding module 1, the first straight-line winding module 2 and the second straight-line winding module 3. The parallel directions between the plurality of winding grooves 10 are perpendicular to both the first direction and the second direction. Furthermore, in order to better adapt to different winding requirements, such as convenient direction change, it is preferred that at least one group of adjacent winding grooves 10 have openings 11 on the wall portion with both ends extending through the winding grooves 10 on both sides of the wall portion. Specifically, each winding module may be provided with an opening groove 11, such as the end winding module 1, the first straight-line winding module 2 and the second straight-line winding module 3 are all provided with an opening groove 11. Specifically, an opening groove 11 may be provided only on the end winding module 1, so that both end winding modules 1 may be provided with an opening groove 11 to meet the transition of the wire turn change groove during the coil winding process. For a single winding module, it is preferred that the opening groove 11 extends from one end of the winding module to the other end of the winding module.

[0039] To accommodate the shape of the winding slot 10, the end winding module 1, the first straight-line winding module 2, and the second straight-line winding module 3 are preferably all semi-cylindrical. Specifically, the end winding module 1, the first straight-line winding module 2, and the second straight-line winding module 3 can all have the same structure. The winding module's R angle can be designed to meet the requirements of different loose-wound winding straight-line transition R angles. During assembly, the end winding module 1 is located symmetrically at the top and bottom ends of the mold, serving as support for the winding of the nose portion of the loose-wound winding.

[0040] When using this winding die to wind random winding coils, the various components can be coordinated and adjusted to meet the needs of winding random windings with different straight side lengths, different spans, and different end lengths. This method has excellent versatility. Furthermore, the winding die in this random winding method can meet the needs of producing random windings with different R angle requirements by configuring different models of end winding modules 1 and straight side winding modules. This method effectively solves the problems of the original random winding method, such as the large number of molds, high costs, poor mold versatility, limited range and frequency of use of a single winding die, and the time and cost waste caused by frequent mold searches and mold changes. Furthermore, this method is simple and convenient to operate and can meet the needs of winding all types of shuttle-type random windings.
