Description
Technical Field
[0001] This utility model belongs to the field of wire conveying technology, specifically relating to an aluminum wire clamping and feeding fixture. Background Technology
[0002] Wire drawing machines are essential equipment in the alloy wire manufacturing industry. Inside the wire drawing machine, alloy wires are drawn from coarse wires into fine wires that meet the standards through the wire drawing die. Wire drawing machines are divided into water tank wire drawing machines, continuous tank wire drawing machines, etc.
[0003] In the existing wire drawing machine, one end of the aluminum wire is inserted into the subsequent processing device during the wire feeding process. For the spool wrapped with aluminum wire, a separate motor is used to control the rotation of the spool to feed the wire. However, during the rotation of the spool to feed the wire, the spool may slip between itself and the sleeved shaft, causing the spool to slide along the axis of the shaft and affecting the subsequent direction of the aluminum wire, that is, it may detach from the wire feeding device and fall off.
[0004] Therefore, an aluminum wire clamping and feeding fixture is designed to solve the technical problem in the prior art where the aluminum wire detaches due to slippage of the spool along the axis of rotation.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0062] Research has revealed that during the wire feeding process of existing wire drawing machines, one end of the aluminum wire is inserted into the subsequent processing device. For the spool wrapped with aluminum wire, a separate motor is used to control the rotation of the spool for wire feeding. However, during the rotation of the spool for wire feeding, slippage occurs between the spool and the sleeved shaft, causing the spool to slide along the axis of the shaft, affecting the subsequent direction of the aluminum wire, i.e., it detaches from the wire feeding device and falls off.
[0063] Based on the above research, this disclosure provides an aluminum wire clamping and feeding fixture. By setting a limiting mechanism, when the spool is sleeved on the hollow rotating shaft, the limiting mechanism abuts against the rotating shaft, restricting the sliding of the rotating shaft along the axis of the hollow rotating shaft during normal rotation and wire feeding, which would cause the aluminum wire to detach. After the wire feeding is completed, the spool can be automatically disengaged by manually pulling the limiting mechanism in the opposite direction of the installation direction, and the spool can be disassembled and replaced.
[0064] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0065] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0066] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0067] In some embodiments, such as Figure 1As shown, before starting the wire feeding operation, the operator manually inserts the spool 10 into the hollow rotating shaft 20. The spool 10 slides on the surface of the hollow rotating shaft 20 until it comes into contact with the surface of the wire feeding plate 1. Then, the rotator 200 is started, and its output end drives the hollow rotating shaft 20 and the spool 10 to rotate to perform the wire feeding operation.
[0068] When the spool 10 is inserted into the hollow shaft 20, the central part of the spool 10 will first press against the inclined surface of the contact member 26. At this time, the telescopic rod 25 is compressed, and the contact member 26 retracts into the sliding position 23. During the sliding installation of the spool 10, the contact member 26 will slide within the sliding position 23 until it abuts against the limiting block 22. At this time, the contact member 26 will stop. Until the spool 10 is slidably installed in place, that is, when it is no longer in contact with the upper surface of the contact member 26, the contact member 26 is pulled back to its original position by the first return spring 28, and the second return spring 27 pushes the telescopic rod 25 to extend, pushing the contact member 26 out again. At this time, the spool is located between the abutment 26 and the wire feeding plate 1. The abutment 26 restricts the spool 10 from sliding freely on the hollow rotating shaft 20, which affects the wire feeding operation. After the wire feeding operation is completed, the operator only needs to manually pull the spool 10 to move it along the installation direction. The outer wall of the spool 10 pushes the abutment 26 to slide in the sliding position 23 until the inclined end of the abutment 26 and the inclined surface 230 are engaged. At this time, as the spool 10 continues to move, the second return spring 27 is compressed again, the telescopic rod 25 retracts, and the abutment 26 retracts into the sliding position 23 until the spool 10 is disengaged from the hollow rotating shaft 20 and resets.
[0069] In some embodiments, such as Figure 2 As shown, after the spool 10 is installed in place, one end of the aluminum wire 11 wound on it is pulled out, passes around the pressure wheel 32, and the aluminum wire 11 is passed through the gap between the two feeding wheels 35. When the wire feeding operation begins, the motor 33 is started, and its output end drives the rotating rod 34 to rotate, which in turn drives the feeding wheel 35 fixed to the rotating rod 34 and the corresponding gear 36 to rotate. Through the meshing relationship between the two gears 36, the other feeding wheel 35 is driven to reverse, thereby realizing the transmission of the aluminum wire 11.
[0070] During the transmission of aluminum wire 11, the driver 30 can be started, and its output end drives the pressure shaft 31 to move down, which in turn drives the pressure wheel 32 to move down, bending and tightening the aluminum wire 11.
[0071] In some embodiments, such as Figure 3As shown, the aluminum wire 11 is transmitted between the two sensors, passes through the wire clamp 13, and remains straight when it enters the next processing step. During normal wire feeding, the processing step continuously extracts the aluminum wire 11. As the aluminum wire 11 is transmitted, when it contacts the lower sensor 122, the control module controls the motor 33 to stop working, that is, the two wire feeding wheels 35 stop feeding and wait for a period of time before restarting the wire feeding (this stop time is coordinated with the time of the subsequent processing step). When the aluminum wire 11 contacts the upper sensor 121 during the second feeding, the control module controls the driver 30 to start, driving the pressure wheel 32 to move down and straighten the aluminum wire 11, so that the aluminum wire 11 between the wire feeding wheel 35, the pressure wheel 32, and the spool 11 remains straight during normal operation.
[0072] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0073] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0074] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature and another element or feature illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0075] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0076] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
