Abstract
Description

[0002] There are many types of materials needed in the preparation of silverware, including silver wires and silver tubes of different sizes. Most of the wire drawing machines currently used use a bayonet to fix the wire drawing die. The position of the wire drawing die is fixed, and the die holes on both sides consume slightly more material during the wire drawing process than the die hole in the middle. In addition, the uneven force on the die holes on both sides can easily cause inconsistent wear of the die holes after long-term use, which greatly affects the accuracy and reduces the service life. In addition, when drawing straight wires, since there is no support in the middle and the texture of the silver wire is relatively soft, especially at the end of wire drawing, the middle silver wire sometimes droops, affecting the accuracy of the long straight wire in subsequent feeding operations.

DETAILED DESCRIPTION
[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example
[0023] like Figure 1-4As shown, a wire drawing machine for preparing silverware comprises a base 1 provided with a driving mechanism, the movable end of the driving mechanism is transmission-connected with a wire drawing device, the wire drawing device comprises a wire bearing structure and a wire clamping structure arranged in sequence, the wire bearing structure is arranged between the driving mechanism and the wire clamping structure, the wire bearing structure and the wire clamping structure are both slidably arranged on the base 1, the driving mechanism can make the wire bearing structure and the wire clamping structure slide on the base 1 at different feeding speeds respectively, the different feeding speeds can be controlled by different rotation speeds of the first screw rod 7 and the second screw rod 12 with the same number of teeth, and can also be controlled by the same rotation speed of the first screw rod 7 and the second screw rod 12 with different numbers of teeth. The specific feeding speed can refer to the public screw rod speed calculation formula, a head plate 8 is mounted above the driving mechanism of the wire bearing structure, and a fixing mechanism for clamping a wire drawing die 11 is arranged on the head plate 8, the wire drawing die 11, the wire bearing wheel 2 and the wire clamp 4 are in a horizontal plane, that is, the silver wire is fed from the wire drawing die 1 After passing through the die hole 1, it is clamped by the wire clamp 4, and the middle section of the silver wire is supported by the wire wheel 2. Card groups are symmetrically arranged on both sides of the fixing mechanism, and the card group includes at least two positioning rods 81. The bottom ends of the positioning rods 81 are connected to the head plate 8, and the wire drawing die 11 is clamped in the middle of the four positioning rods 81. When the die hole is needed, the wire drawing die 11 is moved to the middle position of the two positioning rods 81 of the same card group, that is, the position corresponding to the wire clamp 4. For ease of use, punctuation marks are arranged on the head plate 8 at positions corresponding to the wire clamp 4, and the punctuation marks are used for die hole positioning calibration. The silver wire passes through the die hole and is clamped by the wire clamp 4 to become a straight wire. In order to better prevent the wire drawing die 11 from shaking, a fixing mechanism is arranged, and the fixing mechanism includes a frame plate 105. Positioning bayonet holes 102 are opened on both sides of the frame plate 105 corresponding to the positioning rods 81, and elastic clamping structures that can clamp the wire drawing die 11 are symmetrically arranged at both ends of the frame plate 105. A card group is only provided with two positioning rods 81. When the die hole to be used is on the side of the wire drawing die 11, that is, when the die hole is moved to the middle of the head plate 8, the wire drawing die 11 moves to one side, which is easy to shake during use. Therefore, further, a card group can be provided with multiple equally distributed positioning rods 81, which are extended outward with the two positioning rods 81 as the center point, so that the wire drawing die 11 can be better clamped and fixed during use. Multiple positioning bayonet holes 102 are equidistantly provided on both sides of the frame plate 105 (that is, when four positioning rods 81 are provided, eight, ten or twelve positioning bayonet holes 102 can be provided, so that the position of the wire drawing die 11 can be better adjusted, so that the die hole to be used by the wire drawing die 11 can correspond to the wire clamp 4), so that no matter how the wire drawing die 11 moves, the positioning bayonet hole 102 can be clamped on the positioning rod 81.The fixing mechanism is used to better fix the wire drawing die 11 during wire drawing to prevent the wire drawing die 11 from shaking, and the positioning slots 102 of the frame plate 105 are engaged with the positioning rod 81 and will not move. The wire drawing die 11 is mostly the same size and has the same length as the frame plate 105. A plurality of equidistantly distributed positioning slots 102 and the inner side surface of the clamp plate 10 are in contact with the frame plate 105, that is, the wire drawing die 11, which can also avoid the situation where the fixing mechanism drives the wire drawing die 11 to move.
[0024] In this embodiment, the wire clamping structure includes a wire clamping slide 3 slidably set on the base 1, and a wire clamp 4 is set on the wire clamping slide 3. The wire supporting structure includes a wire supporting slide 5 slidably set on the base 1, and the wire supporting slide 5 includes a slide plate 55. A wire supporting wheel 2 is set on the slide plate 55 corresponding to the wire clamp 4. The wire supporting wheel 2 is set in the form of an I-shaped wheel, and the silver wire is carried in the groove of the I-shaped wheel to complete the supporting function.
[0025] In this embodiment, the slide plate 55 is provided with a sub-slide plate 63 through a linkage structure, and a wire-bearing secondary wheel is provided on the sub-slide plate 63. The linkage structure includes a linkage slot 52 and a linkage rod 62. The linkage slot 52 is provided on the slide plate 55 along the length direction of the base 1. One end of the linkage rod 62 is fixedly connected to the sub-slide plate 63, and the other end extends to the linkage slot 52 and a linkage slider is provided. The linkage slider can be inserted into the linkage slot 52 and can slide along the linkage slot 52. When the length of the pulled silver wire is relatively long, a sub-slide plate 63 can be provided, and the sub-slide plate 63 is pulled by the slide plate 55 through the linkage structure, so that the slide plate 55 and the sub-slide plate 63 starting from the same position gradually pull apart during the movement, so as to better complete the wire-bearing function. When more than two sub-slide plates 63 are needed, a linkage slot 61 is provided on the sub-slide plate 63 accordingly, and a linkage rod 62 is provided on the second sub-slide plate 63. Furthermore, the linkage rod 62 of the linkage structure can also adopt a sleeve structure, so that there is no need to provide the linkage slide groove 52 on the slide plate 55, and the distance between the slide plate 55 and the auxiliary slide plate 63 can be adjusted. Furthermore, by modifying the number of sleeves of the linkage structure sleeve type, the wire clamping slide 3 and the wire holding slide 5 can also be driven by the linkage structure. In the initial position, the slide plate 55 of the wire holding slide 5 is at one end close to the driving mechanism, and the wire clamping slide 3 is at the side of the wire holding slide 5 away from the head plate 8, and the two do not conflict.
[0026] In this embodiment, the driving mechanism includes a servo motor 9, and the output end of the servo motor 9 is rotatably connected to two output shafts through a coupling, one of which is coaxially connected to a first screw rod 7, a first connecting seat 31 is provided on the first screw rod 7, and the first connecting seat 31 is fixedly connected to the bottom end of the wire clamping slide 3, and the other output shaft is coaxially connected to a second screw rod 12, a second connecting seat 54 is provided on the second screw rod 12, and the second connecting seat 54 is fixedly connected to the bottom end of the wire bearing slide 5. When the first screw rod 7 and the second screw rod 12 are arranged in parallel up and down, a through hole is opened in the second connecting seat 54 corresponding to the first screw rod 7. When the feed speed of the first screw rod 7 is set to be twice the feed speed of the second screw rod 12, when the wire clamping slide 3 moves to the tail of the machine, that is, the end of the base 1 away from the head of the machine, the wire bearing slide 5 can move to a position on the side of the head plate 8 at the middle end of the base 1, so when the servo motor 9 drives the wire clamping slide 3 to move toward the head plate 8, the wire clamping slide 3 and the wire bearing slide 5 are always free from conflict.
[0027] In this embodiment, the base 1 is a C-shaped base 1 with an opening facing upward. The head plate 8 is mounted on two curling edges of the opening of the base 1, and a waste discharge port is opened at the bottom of the base 1 for easy cleaning.
[0028] In this embodiment, both ends of the wire clamping structure and the wire bearing structure are symmetrically provided with slide seats 51, and the outer side of the slide seat 51 is provided with an open through slide groove 53 along the length direction of the base 1, and the open through slide groove 53 can be clamped on the curling edge of the C-shaped base 1 and can slide along the length direction of the curling edge. In order to better draw out the long straight wire and ensure that the long straight wire does not sag, the wire clamping slide table 3 and the head plate 8 are slightly higher than the wire bearing slide table 5, thereby ensuring that the silver wire coming out of the wire drawing die 11 is carried on the wire bearing wheel 2 and then clamped by the wire clamp 4, and the whole silver wire is straight.
[0029] In this embodiment, the elastic clamping structure includes a slide bar fixing plate 101, a positioning slide bar 103 is fixedly arranged on the outside of the slide bar fixing plate 101, a hollow sleeve rod 104 is sleeved on the positioning slide bar 103, a clamping plate 10 is fixedly arranged on the outside of the hollow sleeve rod 104, the inner side of the clamping plate 10 can be abutted and connected with the end surface of the corresponding end of the frame plate 105, and a spring 106 is arranged on the outer sleeve of the hollow sleeve rod 104, one end of the spring 106 is connected to the outer wall of the hollow sleeve rod 401, and the other end is connected to the slide bar fixing plate 101. In order to save layout and accuracy, the slide bar fixing plates 101 of the two elastic clamping structures are merged into one.
[0030] In this embodiment, two elastic clamping structures are provided, and the two elastic clamping structures are symmetrically arranged about the frame plate 105. It is ensured that the clamping plates 10 can only move toward and away from each other and will not rotate. In order to facilitate the fixing of the wire drawing die 11, a baffle can be fixedly arranged under the elastic clamping structure below the frame plate 105, so that the baffle can contact with the upper end surface of the wire drawing die 11 to maintain a horizontal state.
[0031] The principles and advantages of the utility model are as follows: first, the wire drawing die 11 is clamped in two card groups, and the wire drawing die 11 is adjusted to move the die hole to be used to the position corresponding to the center of the head plate 8 and the wire clamp 4, the silver wire is passed through the die hole, pulled to the wire clamp 4 and clamped, the middle section of the silver wire is mounted on the wire wheel 2, and the servo motor 9 is started. The servo motor 9 rotates through the first screw rod 7 and the second screw rod 12 to respectively drive the wire clamping slide 3 and the wire supporting slide 5 to move, thereby completing the wire drawing process. During the wire drawing process, the moving speed of the wire clamping slide 3 is twice that of the wire supporting slide 5, so the wire supporting slide 5 can better support the middle section of the silver wire without sagging. If the silver wire is too long, a secondary slide 63 can be appropriately set.
[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
