Description

Technical Field

[0001] This utility model relates to the field of metal forming and processing technology, specifically to a feeding device for a multi-station cold heading machine. Background Technology

[0002] Multi-station cold heading machines are high-efficiency and precision metal plastic forming equipment, widely used in the production of fasteners (such as bolts, nuts, screws), bearing rollers, and irregularly shaped parts. The feeding device, as an important component of the cold heading machine, directly affects production stability, forming accuracy, and mold life.

[0003] The existing feeding device consists of a wire feeding frame and a conveyor frame. The wire feeding frame is used to fix and carry the wire coils. Multiple straightening rollers are staggered on the top of the conveyor frame. The straightening rollers are used to eliminate wire bending, pull out the wire coils, and guide the wire through the inner walls of the staggered straightening rollers. When the wire is processed by the cold heading machine, the wire coils rotate on the outer wall of the wire feeding frame and are conveyed to the die position of the cold heading machine for processing under the correction of the multiple straightening rollers. When the wire coils are processed, oxidation and rust will inevitably appear. When the wire coils are processed by the die, the oxidation and rust will wear down the die and affect the uneven flow resistance of the wire, resulting in errors in the finished product. The conventional treatment method is manual grinding or offline pickling, which is too time-consuming and labor-intensive. Therefore, a feeding device for a multi-station cold heading machine is designed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a feeding device for a multi-station cold heading machine, which solves the technical problem of mold wear caused by impurities on the surface of the die in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a multi-station cold heading machine, comprising a conveyor table, a turntable rotatably connected to the top of the conveyor table, a guide rail provided on the upper surface of the conveyor table near the turntable, a sliding plate slidably connected to the inner wall of the guide rail, a rack fixedly connected to the outer wall of the sliding plate, a wire brush fixedly connected to the end of the sliding plate near the turntable, a gear meshing with the outer wall of the rack, a rotating shaft fixedly connected to the inner wall of the gear, the bottom end of the rotating shaft rotatably connected to the top of the conveyor table, a groove provided on the inner wall of the sliding plate, a sliding block slidably connected to the inner wall of the groove, an auxiliary wheel rotatably connected to the inner wall of the sliding block, a conveyor frame fixedly connected to the upper surface of the conveyor table away from the turntable, a clamping platform fixedly connected to the top of the conveyor frame, and a clamping mechanism provided on the inner wall of the clamping platform.

[0006] As a preferred embodiment of this utility model, a connecting shaft is fixedly connected at the connection between the conveyor table and the turntable, and several positioning pins are fixedly connected around the top of the turntable.

[0007] As a preferred embodiment of this utility model, a handwheel is fixedly connected to the top end of the rotating shaft, a fixing frame is sleeved on the outer wall of the rotating shaft, and the bottom end of the fixing frame is fixedly connected to the top end of the conveyor table.

[0008] In a preferred embodiment of this utility model, a spring is fixedly connected to the inner wall of the groove, one end of the spring is fixedly connected to the end of the sliding block away from the auxiliary wheel, and the inner wall of the groove is slidably connected to the outer wall of the turntable.

[0009] As a preferred embodiment of this utility model, a support frame is fixedly connected to the upper surface of the conveyor table and to one end near the conveyor frame. A guide window is fixedly connected to the top of the support frame, and two sets of guide rods are symmetrically rotatably connected to the inner wall of the guide window.

[0010] As a preferred embodiment of this utility model, two straightening wheels are symmetrically rotatably connected to the top of the conveyor frame and the end near the guide rod. The top of the two straightening wheels is fixedly connected to a second gear, and the outer walls of the two second gears mesh with each other.

[0011] As a preferred technical solution of this utility model, the clamping mechanism includes a main slide plate that is slidably connected to the top of the clamping platform, and two gears are symmetrically rotatably connected to the top of the clamping platform at one end near the main slide plate.

[0012] As a preferred technical solution of this utility model, two auxiliary slide plates are symmetrically slidably connected to the top of the clamping platform and the end near the gear three. Several racks two are symmetrically fixedly connected to the outer walls of the auxiliary slide plates and the main slide plate.

[0013] As a preferred technical solution of this utility model, the outer wall of the rack two meshes with the outer wall of the gear three, and the top of the auxiliary slide plate and the main slide plate are rotatably connected with several clamping wheels.

[0014] In a preferred embodiment of this utility model, a lead screw is threadedly connected to the inner wall of the clamping platform, and the outer wall of the lead screw is threadedly connected to the inner wall of the main slide plate. The beneficial effects of this embodiment are as follows:

[0015] 1. In this utility model, a sliding plate and a wire brush are provided on one side of the turntable. When the wire rod is fed to the cold heading machine for processing and traction, the wire rod is pulled to the turntable and rotates. The operator can rotate the rotating shaft to drive the gear to rotate. The gear drives the rack and the sliding plate to slide on the inner wall of the guide rail through meshing. The sliding plate and the wire brush rub against the surface of the wire rod through sliding contact. The rotation of the wire rod realizes automatic grinding and cleaning, removing oxide scale, rust or dirt from the surface of the wire rod, thereby reducing the wear between it and the mold and improving production efficiency. At the same time, a sliding block and an auxiliary wheel are provided between the turntable and the sliding plate. The auxiliary wheel reduces the friction between the turntable and the sliding plate and stabilizes the mutual movement between the turntable and the sliding plate.

[0016] 2. This utility model features a clamping mechanism at the top of the clamping table. Before conveying the wire, the operator can adjust the clamping of wires of different sizes by rotating the lead screw. When the lead screw rotates, it drives the main slide plate to slide at the top of the clamping table through a threaded connection. The main slide plate drives the racks on both sides to slide. The racks rotate the gears through meshing. The gears push the auxiliary slide plates and racks on both sides through meshing. Through the mutual transmission of the gears, the main slide plate and auxiliary slide plates drive the clamping wheels to slide synchronously in opposite directions. The synchronous sliding of the clamping wheels clamps and fixes the conveying section of the wire. The synchronous clamping of the clamping wheels enables the device to stably convey wires of different sizes and stably guide the wires to the mold for processing. Attached Figure Description

[0030] like Figures 1-5 The diagram illustrates a feeding device for a multi-station cold heading machine according to an embodiment of the present invention. It includes a conveyor table 1, with a turntable 102 rotatably connected to the top of the conveyor table 1. A guide rail 201 is provided on the upper surface of the conveyor table 1, near the end of the turntable 102. A sliding plate 2 is slidably connected to the inner wall of the guide rail 201. A rack 203 is fixedly connected to the outer wall of the sliding plate 2. A wire brush 202 is fixedly connected to the end of the sliding plate 2 near the turntable 102. Gears mesh on the outer wall of the rack 203. Gear 204 has a rotating shaft 205 fixedly connected to its inner wall. The bottom end of the rotating shaft 205 is rotatably connected to the top end of the conveyor table 1. The inner wall of the sliding plate 2 is provided with a groove 3. The inner wall of the groove 3 is slidably connected with a sliding block 301. The inner wall of the sliding block 301 is rotatably connected with an auxiliary wheel 302. The upper surface of the conveyor table 1 and the end located away from the turntable 102 is fixedly connected with a conveyor frame 5. The top end of the conveyor frame 5 is fixedly connected with a clamping platform 6. The inner wall of the clamping platform 6 is provided with a clamping mechanism 7.

[0031] For example, such as Figure 2 As shown, a connecting shaft 101 is fixedly connected at the connection between the conveyor table 1 and the turntable 102, and several positioning pins 103 are fixedly connected around the top of the turntable 102.

[0032] It should be noted that a connecting frame is provided in the middle of the turntable 102. The connecting frame is connected to the connecting shaft 101 to realize the rotation of the turntable 102 on the top of the conveyor table 1. When the disc element is placed on the turntable 102, the positioning pin 103 is used to support and position the disc element. When the disc element rotates, the disc element achieves the rotation of the turntable 102 through the friction between the disc element, the positioning pin 103 and the turntable 102.

[0033] For example, such as Figure 3 As shown, a handwheel 206 is fixedly connected to the top of the rotating shaft 205, and a fixing frame 207 is sleeved on the outer wall of the rotating shaft 205. The bottom end of the fixing frame 207 is fixedly connected to the top of the conveyor table 1.

[0034] It should be noted that the bottom end of the rotating shaft 205 is rotatably connected to the top end of the conveyor table 1. A fixed frame 207 is fixed at the connection between the rotating shaft 205 and the conveyor table 1. The inner wall of the fixed frame 207 is provided with a bearing. The rotating shaft 205 is supported by the fixed frame 207. When the operator rotates the handwheel 206, the handwheel 206 drives the rotating shaft 205 and the gear 204 to rotate.

[0035] For example, such as Figure 2 As shown, a spring 303 is fixedly connected to the inner wall of the groove 3. One end of the spring 303 is fixedly connected to the end of the sliding block 301 away from the auxiliary wheel 302. The inner wall of the groove 3 is slidably connected to the outer wall of the turntable 102.

[0036] It should be noted that the operator slides between the inner wall of the groove 3 and the outer edge of the turntable 102. When the operator rotates the handwheel 206 to push the sliding plate 2 to slide radially at the top of the turntable 102, the inner wall of the groove 3 will slide radially along the outer edge of the turntable 102. When the inner wall of the groove 3 pushes the sliding block 301 to contact the outer wall of the turntable 102, the sliding block 301 will use the auxiliary wheel 302 to reduce the friction with the turntable 102. At the same time, the sliding block 301 will squeeze the spring 303. At this time, the turntable 102 will contact the auxiliary wheel 302 when rotating. With the cooperation of the spring 303 and the auxiliary wheel 302, the mutual movement between the turntable 102 and the sliding plate 2 is stabilized.

[0037] For example, such as Figure 4 As shown, a support frame 4 is fixedly connected to the upper surface of the conveyor table 1 and to one end near the conveyor frame 5. A guide window 401 is fixedly connected to the top of the support frame 4. Two sets of guide rods 402 are symmetrically rotatably connected to the inner wall of the guide window 401.

[0038] Two straightening wheels 501 are symmetrically rotatably connected to the top of the conveyor frame 5, near the end close to the guide rod 402. Gears 502 are fixedly connected to the top of the two straightening wheels 501, and the outer walls of the two gears 502 mesh with each other.

[0039] It should be noted that during the conveying process, the wire needs to pass through multiple guide rods 402 on the inner wall of the guide window 401. Guided by the multiple guide rods 402, the wire will be horizontally guided between two straightening rollers 501. During the conveying process, the wire will drive the straightening rollers 501 to rotate due to friction. When one of the straightening rollers 501 rotates, it will drive the top gear 502 to rotate. The gear 502 will drive the other gear 502 to rotate through meshing. The gear 502 will drive the other straightening roller 501 to rotate, realizing the synchronous rotation of the two straightening rollers 501. The synchronously rotating straightening rollers 501 can stabilize the conveying path of the wire and have a pushing effect on the outer wall of the wire.

[0040] For example, such as Figure 5 As shown, the clamping mechanism 7 includes a main slide plate 702 that is slidably connected to the top of the clamping platform 6, and two gears 701 that are symmetrically rotatably connected to the top of the clamping platform 6 near the main slide plate 702.

[0041] Two auxiliary slide plates 703 are symmetrically slidably connected to the top of the clamping platform 6 and the end near the gear 3 701. Several racks 2 704 are symmetrically fixed to the outer walls of the auxiliary slide plates 703 and the main slide plate 702.

[0042] It should be noted that the top of the clamping platform 6 is vertically provided with three sliding grooves. The inner wall of the sliding grooves is slidably connected to the bottom of the main slide plate 702 and the auxiliary slide plate 703. Two gears 701 are rotatably connected at the connection of the three sliding grooves. Two racks 704 are symmetrically fixed to the outer wall of the main slide plate 702. One side of the auxiliary slide plate 703 is fixedly connected to a single rack 704. The outer walls of the multiple racks 704 mesh with the gears 701.

[0043] For example, such as Figure 5 As shown, the outer wall of rack 2 704 meshes with the outer wall of gear 3 701, and several clamping wheels 705 are rotatably connected to the top of both the auxiliary slide plate 703 and the main slide plate 702.

[0044] The inner wall of the clamping table 6 is threaded with a lead screw 706, and the outer wall of the lead screw 706 is threaded with the inner wall of the main slide plate 702.

[0045] It should be noted that when the operator rotates the lead screw 706, the lead screw 706 pushes the main slide plate 702 to slide on the top of the clamping table 6 through the threaded engagement. The main slide plate 702 drives the rack 2 704 and the clamping wheel 705 to slide. When the rack 2 704 of the main slide plate 702 slides, it will drive the gear 3 701 on both sides to rotate. The rotation of the gear 3 701 on both sides will push the rack 2 704 of the auxiliary slide plate 703 to slide through meshing. At this time, the auxiliary slide plate 703 and the main slide plate 702 achieve synchronous movement in opposite directions under mutual linkage. During the sliding process, the clamping wheel 705 of the auxiliary slide plate 703 and the main slide plate 702 will move closer to the outer wall of the wire and clamp it.

[0046] Working principle and usage process of this utility model:

[0047] The specific operating procedure is as follows: The operator needs to place the workpiece on the top of the turntable 102 and position it using the positioning pin 103. Then, the operator leads out the wire from the workpiece and passes the wire through the inner wall of the guide window 401 at the top of the conveyor frame 5. The outer wall of the wire is then passed between multiple guide rods 402. After passing through, one end of the wire is passed between two straightening wheels 501. Finally, the wire is passed through the top of the auxiliary slide plate 703 and the main slide plate 702. After passing through, the operator needs to rotate the lead screw 706, which engages through a threaded connection. The main slide plate 702 is pushed to slide on the top of the clamping platform 6. The main slide plate 702 drives the rack 2 704 and the clamping wheel 705 to slide. When the rack 2 704 of the main slide plate 702 slides, it drives the gear 3 701 on both sides to rotate. The rotation of the gear 3 701 on both sides drives the rack 2 704 of the auxiliary slide plate 703 to slide through meshing. At this time, the auxiliary slide plate 703 and the main slide plate 702 achieve synchronous movement in opposite directions under mutual linkage. During the sliding process, the clamping wheel 705 of the auxiliary slide plate 703 and the main slide plate 702 will move closer to the outer wall of the wire and clamp it.

[0048] After clamping, one end of the wire will be pulled by the cold heading machine. At this time, the operator needs to turn the handwheel 206. The handwheel 206 drives the rotating shaft 205 and gear 204 to rotate. Gear 204 drives rack 203 to move through meshing. Rack 203 drives sliding plate 2 to slide on the inner wall of guide rail 201. Sliding plate 2 drives wire brush 202 to slide and contact the outer wall surface of the coil. At the same time, the wire is pulled and pulls the coil. The coil rotates with the turntable 102 on the outer wall of connecting shaft 101 through friction. When the coil rotates, it will rub against the wire brush 202. The wire brush 202 cleans the surface through the rotation of the disc.

[0049] When the operator rotates the handwheel 206 to push the sliding plate 2, the sliding block 301 on the inner wall of the groove 3 of the sliding plate 2 will drive the auxiliary wheel 302 to resist against the outer wall of the turntable 102. At this time, the spring 303 on one side of the sliding block 301 will squeeze during the resistance process. The auxiliary wheel 302 can reduce the friction with the outer wall of the turntable 102. Through the cooperation of the spring 303 and the auxiliary wheel 302, the mutual movement between the sliding plate 2 and the turntable 102 is stabilized.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
