Description

Technical Field

[0001] The invention relates to the field of plate and strip grinding, and in particular to a wire drawing mechanism and application thereof. Background Art

[0002] The plates and strips are usually made by hot rolling process. Before actual use, rust, oxide scale, etc. will appear on the surface of the plates and strips, and the surface of the plates and strips needs to be brushed by brush rollers. To facilitate disassembly and maintenance, an existing brush roller structure is configured to sleeve multiple grinding brush discs on the roller shaft. The grinding brush disc includes a brush disc, and the inner side of the brush disc is provided with multiple wire holes evenly distributed along the circumferential direction. Wires made of resin material need to be passed through the wire holes. The wires are folded in half along the radial direction away from the brush disc to form two strands located at both ends of the brush disc. The two strands need to be fixed together by wire winding or welding to form a wire bundle for grinding the surface of the plates and strips.

[0003] For example, in the patent of the wire threading mechanism designed by the applicant previously with the announcement number CN112353088, the brush disc without wire threading is installed concentrically on the turntable, and the two are connected to rotate synchronously; the turntable is driven to rotate by a stepper motor, and each wire hole is aligned with the travel path of the material wire; when threading the wire, the wire threading mechanism threads the material wire on the brush disc, and then the wire bending mechanism bends the material wire threaded on the brush disc into a U shape, the wire bending mechanism includes two working arms, and the working arms are provided with clamping blocks for dividing the material wire, after the working arms are lifted from bottom to top, the two clamping blocks bend the cut material wire into a U-shaped wire; then a constraint ring is put on the bent material wire by the ring mechanism; then the stepper motor rotates to align the next wire hole with the material wire, alternating back and forth until all the wire holes on the brush disc are planted.

[0004] like Fig. 9 As shown, the wire holes are divided into wire-threaded holes where the material wire has been inserted and wire-waiting holes where the material wire has not been inserted. At the wire bundle of the wire-threaded holes, although the ring binds the two strands together (the ring is not shown), the unbound wire part is easy to fork circumferentially to the side of the wire-waiting hole adjacent to the wire-threaded hole because of its own elasticity. When the wire-waiting hole is folded, the forked wire will overlap with the wire in the wire-waiting hole, and it is easy to be rolled into the next group of wire strands by the clamp, affecting the wire planting efficiency and quality. Summary of the invention

[0005] The present invention provides a wire drawing mechanism and its application, wherein a driving member drives a rotating shaft to rotate along its own axis, so that a movable lever linked by the rotating shaft can be moved to between adjacent holes for threaded wire and holes for waiting wire on a brush plate, and forked wires are drawn to one side of the holes for threaded wire, thereby preventing the clamping blocks on the wire bending mechanism from rolling the forked wires into the next group of strands, thereby ensuring that the wire seeding process proceeds normally and improving the quality and efficiency of wire seeding.

[0006] The technical solution of the present invention is achieved in this way: A wire drawing mechanism, comprising: The wire drawing assembly includes a base, the base is connected to a rotating shaft that can rotate along its own axis, the rotating shaft is connected to a movable lever parallel to the rotating shaft through a linkage rod, and the movable lever is used to draw together the wire bundle in the wire-threaded hole adjacent to the wire hole to be fed on the brush disc; A driving member, the driving member is directly or indirectly connected to the rotating shaft to drive the rotating shaft to rotate; The wire drawing mechanism has a working state and a reset state. When the wire drawing mechanism is in the working state, the driving member drives the rotating shaft to rotate so that the movable lever moves from the initial position to between the adjacent wire-threaded holes and the wire-waiting holes on the brush disk, so as to draw the wire bundles in the wire-threaded holes to one side of the wire-threaded holes; when the wire drawing mechanism is in the reset state, the driving member drives the rotating shaft to rotate in the opposite direction so that the movable lever moves in the opposite direction to the initial position.

[0008] Preferably, the transmission rod is a screw, and the tooth groove is a spiral groove arranged on the screw; compared with opening a standard tooth groove on the transmission rod, directly using a screw with a spiral groove is lower in cost, and at the same time, the meshing effect of the tooth groove and the tooth portion can be ensured.

[0009] Preferably, a accommodating cavity is provided on the base, and the rotating shaft has a matching portion which is penetrated in the accommodating cavity, the matching portion is fixedly connected with the swinging tooth part, and a guide hole which is connected to the outside is provided on the side wall of the accommodating cavity, and the transmission rod is slidably connected in the guide hole; the accommodating cavity can accommodate the transmission assembly in the base, reduce the space it occupies in the wire drawing mechanism, optimize the structural layout of the wire drawing mechanism, and facilitate the installation of the wire drawing mechanism to the wire threading mechanism for wire drawing.

[0010] Preferably, the driving member is a cylinder, and the piston rod of the cylinder is indirectly connected to the transmission rod via a connecting plate.

[0011] Preferably, the connecting plate is provided with a connecting sleeve inserted into the guide hole, and the end of the transmission rod is provided with a screw hole corresponding to the position of the connecting sleeve. The screw passes through the connecting sleeve and is screwed into the screw hole to connect the transmission rod to the connecting plate; a threaded rod is connected to the piston rod of the cylinder, and an internal threaded sleeve corresponding to the threaded rod is connected to the connecting plate. After the threaded rod and the internal threaded sleeve are matched, they are locked by a nut to connect the piston rod to the connecting plate.

[0012] Preferably, a waist-shaped groove is provided on the connecting plate, and a contraction section matching the width of the waist-shaped groove is provided in the middle of the internal threaded sleeve, and the contraction section is located in the waist-shaped groove.

[0013] Preferably, the extension direction of the waist-shaped slot is perpendicular to the extension and retraction direction of the piston rod; the waist-shaped slot extends and forms a mounting notch at the corresponding end of the connecting plate to allow the contraction section to be stuck in or out; so as to facilitate the installation and disassembly of the internal threaded sleeve.

[0014] Preferably, the driving member is a motor directly connected to the rotating shaft; the output shaft of the motor can be connected to the end of the rotating shaft through a key connection or a coupling to drive the rotating shaft to rotate.

[0015] Based on the application of the wire drawing mechanism, the following steps are included: S1: The wire pulling mechanism is set at the corresponding position of the wire threading mechanism, and the axis direction of the movable pull rod is consistent with the axis direction of the brush plate; S2: After the first wire hole to be fed on the brush plate is seeded with wire by the wire threading mechanism and converted into a threaded hole, the brush plate is rotated to make the next wire hole to be fed with wire in cooperation with the wire threading mechanism for seeding; S3: Switch the wire drawing mechanism to the working state, so that the movable drawing rod moves from the initial position to between the adjacent wire-threaded hole and the wire-to-be-threaded hole on the brush plate, so as to draw the wire bundle in the wire-threaded hole to one side of the wire-threaded hole; S4: When the wire seeding is completed in the corresponding wire hole to be fed and converted into a wire-threaded hole, the wire pulling mechanism is switched to a reset state, so that the movable pull rod moves in the reverse direction to the initial position; S5: Repeat steps S2-S4 to successfully complete the seeding in each thread hole on the brush plate.

[0016] Preferably, the wire drawing assembly also includes a fixed lever arranged next to the movable lever. In step S5, when the last wire hole to be fed on the brush disc is being seeded, the two wire-threaded holes adjacent to the last wire hole have wire bundles, and the movable lever moves from the initial position to between the last wire hole to be fed and one of the adjacent wire-threaded holes, and draws one of the wire bundles to the wire-threaded hole on the corresponding side; at this time, the fixed lever is between the last wire hole to be fed and the other adjacent wire-threaded hole, and draws the other wire bundle to the wire-threaded hole on the other side; when the last wire hole to be fed is being seeded, the wire bundles on both sides will not be drawn in.

[0017] Preferably, the wire drawing mechanism is driven by a positioning cylinder, and the extension and retraction direction of the piston rod of the positioning cylinder is the same as the axial direction of the brush disc; in step S3, the piston rod of the positioning cylinder extends and makes the wire drawing mechanism approach the brush disc along the axial direction of the brush disc, and after step S4, the piston rod of the positioning cylinder retracts and makes the wire drawing mechanism move away from the brush disc along the axial direction of the brush disc; when the positioning cylinder drives the wire drawing mechanism to approach the brush disc, it is convenient to draw together the corresponding wire bundles on the brush disc, and when the positioning cylinder drives the wire drawing mechanism away from the brush disc, it is possible to avoid interference with the ring mechanism and the wire bending mechanism.

[0018] The beneficial effects of the present invention using the above technical solution are: Since the material wire is elastic, it is difficult to avoid the bifurcation of the material wire in the threaded hole. The wire drawing mechanism of the present invention drives the rotating shaft to rotate, so that the rotating shaft is linked to the movable lever through the linkage rod and moves from the circumferential direction of the brush plate to between the adjacent threaded hole and the hole to be threaded on the brush plate, so that the movable lever can bring the bifurcated material wire together. When threading and bending the wire in the hole to be threaded, there is no need to worry that the clamping block on the wire bending mechanism will draw in the bifurcated material wire in the threaded hole. After the threading and bending in the hole to be threaded are completed, the movable lever can be reset in the reverse direction to prepare for the next wire drawing work. The design of the entire wire drawing mechanism is simple and ingenious, which improves the quality and efficiency of wire seeding.

[0019] A receiving cavity for accommodating the transmission assembly is provided on the base, so that the transmission assembly can be hidden therein, thereby reducing the volume space occupied by the transmission assembly in the entire wire drawing mechanism and miniaturizing the structure of the entire wire drawing mechanism, so that it can be more conveniently installed on the wire threading mechanism to complete the corresponding wire drawing work.

[0020] The wire drawing mechanism is installed and applied to the wire threading mechanism, so that when the wire threading mechanism is seeding wire in each wire hole on the brush disc, the wire bundles in the threaded holes are pulled together, ensuring that each wire hole will not be disturbed by adjacent wire bundles when seeding wire, ensuring that wire seeding is completed smoothly in each wire hole on the brush disc.

[0021] Taking into account that when the last wire hole is being seeded, wire bundles have already been formed on both sides of the last wire hole, and therefore the movable lever of the wire pulling mechanism can only pull together the wire bundles on one side, the present invention provides a fixed lever beside the movable lever. When the last wire hole is being seeded, the fixed lever can naturally pull together the wire bundles on the other side, thereby avoiding the last wire hole being affected by the wire bundles on the other side when being seeded, thereby further improving the quality of the seeded wire.

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] The present invention has multiple embodiments, and the specific implementation methods are as follows: Example 1: Figure 1-7 As shown, this embodiment provides a wire drawing mechanism, which can draw together multiple forked wires in the wire-threaded holes adjacent to the wire holes to be fed on the brush plate to prevent the forked wires from being drawn into the next group of strands. The wire drawing mechanism includes: The wire drawing assembly includes a base 5, a rotating shaft 1 that can rotate along its own axis is connected to the base 5, and a movable lever 2 parallel to the rotating shaft 1 is connected to the rotating shaft 1 through a linkage rod 3. The movable lever 2 is used to draw the wire bundle in the threaded wire hole adjacent to the wire hole to be fed on the brush disc; when the wire drawing mechanism is set on the wire threading mechanism for wire drawing, the axis direction of the movable lever 2 is the same as the axis direction of the brush disc; A driving member, the driving member is directly or indirectly connected to the rotating shaft 1 to drive the rotating shaft 1 to rotate; The wire drawing mechanism has a working state and a reset state. When the wire drawing mechanism is in the working state, the driving member drives the rotating shaft 1 to rotate, so that the movable lever 2 moves from the initial position to between the adjacent wire-threaded holes and the wire-to-be-threaded holes on the brush disc, so as to draw the wire bundles in the wire-threaded holes to one side of the wire-threaded holes; specifically, when drawing the wire, the movable lever 2 moves from the initial position along the circumferential direction of the rotating shaft 1, and gradually approaches and acts on the wire bundles in the wire-threaded holes from the circumferential direction of the brush disc; when the wire drawing mechanism is in the reset state, the driving member drives the rotating shaft 1 to rotate in the opposite direction, so that the movable lever 2 moves in the opposite direction to the initial position; in preparation for the next wire drawing work, until all the wire holes of the brush disc are fully planted.

[0026] Furthermore, the driving member can be directly connected to the rotating shaft 1 to drive the movable lever 2 to move, or the driving member can be indirectly connected to the rotating shaft 1 through a transmission assembly; in this embodiment, the transmission assembly includes a transmission rod 8 slidably connected to the base 5, and a plurality of tooth grooves 81 are provided on the transmission rod 8. A swinging tooth member 11 is fixedly connected to the shaft body of the rotating shaft 1, and the swinging tooth member 11 has a plurality of tooth portions 111 matching the tooth grooves 81. The driving member is a cylinder 4, and the piston rod of the cylinder 4 is indirectly connected to the transmission rod 8 through a connecting plate 6. The piston rod of the cylinder 4 can be extended and retracted to drive the transmission rod 8 to slide on the base 5, so that the tooth grooves 81 cooperate with the tooth portions 111 to drive the rotating shaft 1 to rotate.

[0027] Furthermore, compared with providing a standard tooth-shaped groove on the rod body of the transmission rod 8, the transmission rod 8 in this embodiment has lower cost and is easier to process, that is, the transmission rod 8 is a screw rod, and the tooth groove 81 is a spiral groove arranged on the screw rod; compared with providing a standard tooth-shaped groove on the transmission rod 8, directly using a screw rod with a spiral groove has lower cost, and at the same time can also ensure the meshing effect of the tooth groove 81 and the tooth portion 111.

[0028] Furthermore, the volume of the wire drawing mechanism needs to be miniaturized, and the miniaturized wire drawing mechanism is easier to be installed in the corresponding position of the wire threading mechanism. Therefore, in this embodiment, a accommodating chamber 51 is provided on the base 5, and the rotating shaft 1 has a matching portion penetrated in the accommodating chamber 51, and the matching portion is fixedly connected to the swinging tooth 11, and the side wall of the accommodating chamber 51 is provided with a guide hole 52 connected to the outside, and the transmission rod 8 is slidably connected in the guide hole 52; the accommodating chamber 51 can accommodate the transmission assembly in the base 5, reduce the space it occupies in the wire drawing mechanism, optimize the structural layout of the wire drawing mechanism, and facilitate the installation of the wire drawing mechanism to the wire threading mechanism for wire drawing.

[0029] Furthermore, the connection relationship among the connecting plate 6, the transmission rod 8 and the cylinder 4 is as follows: the connecting plate 6 is provided with a connecting sleeve 61 inserted into the guide hole 52, the end of the transmission rod 8 is provided with a screw hole corresponding to the position of the connecting sleeve 61, the screw passes through the connecting sleeve 61 and is screwed into the screw hole, so that the transmission rod 8 is connected to the connecting plate 6; the piston rod of the cylinder 4 is connected with a threaded rod 41, and the connecting plate 6 is connected with an internal threaded sleeve 7 corresponding to the threaded rod 41, and the threaded rod 41 is matched with the internal threaded sleeve 7 and is locked by a nut, so that the piston rod is connected to the connecting plate 6.

[0030] Furthermore, in order to facilitate the rapid alignment of the threaded rod 41 with the internal threaded hole of the internal threaded sleeve 7 during installation, a waist-shaped groove is provided on the connecting plate 6, and the extension direction of the waist-shaped groove is perpendicular to the extension and contraction direction of the piston rod; the middle part of the internal threaded sleeve 7 has a contraction section 71 matching the width of the waist-shaped groove, and the contraction section 71 is in the waist-shaped groove. During installation, the waist-shaped groove facilitates the sliding of the contraction section 71 to align the internal threaded hole of the internal threaded sleeve 7 with the threaded rod 41; and in order to facilitate the contraction section 71 to be inserted into or removed from the waist-shaped groove, the waist-shaped groove extends and forms an installation notch 62 at the corresponding end of the connecting plate 6 to allow the contraction section 71 to be inserted into or removed from the waist-shaped groove; so as to facilitate the installation and disassembly of the internal threaded sleeve 7.

[0031] Based on the application of the wire drawing mechanism, the following steps are included: S1: The wire pulling mechanism is arranged at the corresponding position of the wire threading mechanism, and the wire threading mechanism can be the wire threading mechanism in the background technology or other wire threading mechanisms; and the axis direction of the movable lever is kept consistent with the axis direction of the brush plate; and the movable lever 2 can be moved along the circumferential direction of the brush plate to between the threaded wire hole and the wire hole to be fed; S2: After the first wire hole to be fed on the brush plate is seeded with wire by the wire threading mechanism and converted into a threaded hole, the brush plate is rotated to make the next wire hole to be fed with wire in cooperation with the wire threading mechanism for seeding; S3: Switch the wire drawing mechanism to the working state, so that the movable lever 2 moves from the initial position to between the adjacent wire-threaded hole and the wire-to-be-threaded hole on the brush disc, so as to draw the wire bundle in the wire-threaded hole to one side of the wire-threaded hole; S4: When the wire seeding is completed in the corresponding wire hole to be fed and converted into a wire threaded hole, the wire pulling mechanism is switched to a reset state, so that the movable pull rod 2 moves in the reverse direction to the initial position; S5: Repeat steps S2-S4 to successfully complete the seeding in each thread hole on the brush plate.

[0032] Further, if Figure 7As shown, considering that when the last wire hole to be fed on the brush disc is being seeded, wire bundles have been formed on both sides of the last wire hole to be fed, the movable lever of the wire drawing mechanism can only draw together the wire bundles on one side. Therefore, the wire drawing assembly also includes a fixed lever 2a arranged next to the movable lever 2. In step S5, when the last wire hole to be fed on the brush disc is being seeded, the two wire-threaded holes adjacent to the last wire hole to be fed have wire bundles, and the movable lever 2a moves from the initial position to between the last wire hole to be fed and one of the adjacent wire-threaded holes, and draws one of the wire bundles to the wire-threaded hole on the corresponding side; at this time, the fixed lever 2a is between the last wire hole to be fed and the other adjacent wire-threaded hole, and draws together the other wire bundle to the wire-threaded hole on the other side; when the last wire hole to be fed is being seeded, the wire bundles on both sides will not be drawn in.

[0033] Further, taking the wire threading mechanism disclosed in the background technology as an example, after the wire drawing mechanism completes the wire drawing work, the wire bending operation and the ring sleeve operation are still required on the wire threading mechanism. If the wire drawing mechanism continues to stay near the brush disc, it may interfere with the wire bending mechanism and the constraint mechanism, affecting the next step of the wire bending operation and the ring sleeve operation. Therefore, in this embodiment, the wire drawing mechanism is driven by a positioning cylinder 9, and the extension direction of the piston rod of the positioning cylinder 9 is the same as the axial direction of the brush disc; the positioning cylinder 9 is connected to a mounting seat 91, and the wire drawing mechanism is arranged on the mounting seat 91. In step S3, the piston rod of the positioning cylinder 9 extends and makes the wire drawing mechanism approach the brush disc along the axial direction of the brush disc. After step S4, the piston rod of the positioning cylinder 9 retracts and makes the wire drawing mechanism move away from the brush disc along the axial direction of the brush disc; the positioning cylinder 9 drives the wire drawing mechanism to approach the brush disc to facilitate the pulling of the corresponding wire bundles on the brush disc, and the positioning cylinder 9 drives the wire drawing mechanism away from the brush disc to avoid interfering with the ring sleeve mechanism and the wire bending mechanism.

[0034] Example 2: Figure 8 As shown, the difference between this embodiment and the above embodiment is that the driving member is a motor 4a directly connected to the rotating shaft 1; specifically, the motor 4a is installed outside the accommodating cavity 51, and the output shaft of the motor 4a passes through the base 5 and is connected to the end of the rotating shaft 1 through a key connection or a coupling to drive the rotating shaft 1 to rotate, thereby driving the movable lever 2 to move or reset to complete the wire drawing work, thereby achieving the same effect as in the above embodiment.

[0035] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
