Description

Technical Field

[0001] This invention relates to the field of metal manufacturing equipment technology, specifically a feeding device for a silver-copper alloy contact repressing machine. Background Technology

[0002] Silver-copper alloy contacts are key components in electrical switches, and their manufacturing process often requires a re-pressing process to shape the blanks. The feeding device, as an important part of the re-pressing machine, is responsible for accurately and orderly feeding the contact blanks into the mold; its performance directly affects production efficiency, product consistency, and operational safety. Traditional feeding methods rely heavily on manual labor or simple mechanical assistance, making them unsuitable for the demands of efficient, automated, and continuous production.

[0003] For example, application number "CN201810121143.6" discloses a static contact spring feeding mechanism. The spring passes through a transition block via a feeding track and enters the anti-formation groove set on the anti-formation seat. At this time, the spring is exactly located at the lower end of the stop part set on the stop block. The stop part effectively restricts the position of the spring and prevents it from tilting up. Subsequently, the feeding cylinder pushes the anti-formation seat to move, thereby driving the push head fixed to the anti-formation seat to move forward. The first wedge part set on the push head and the second wedge part set on the stop block interact, causing the spring to compress, thereby driving the stop part to move backward until the trigger block triggers the proximity switch, and the feeding cylinder stops. The external handling equipment can then handle the spring placed in the anti-formation groove. This device has a simple structure and can automatically feed the spring at a fixed point with precision, effectively improving production efficiency. However, the feeding devices in the prior art often have problems such as insufficient automation, poor control of feeding accuracy, and low equipment versatility, which leads to frequent manual intervention in the production process, affecting the overall efficiency and safety. Meanwhile, during the feeding process, excessive feeding or material accumulation can easily cause mold blockage and increase product defect rates. Furthermore, most feeding devices have fixed structures, making them difficult to adapt flexibly to different production lines, thus hindering their widespread application in actual production. Therefore, there is an urgent need for a feeding device that can achieve precise, continuous, and automated feeding, with good adaptability and stability, to meet the demands of modern high-efficiency production. Summary of the Invention

[0004] This invention provides a feeding device for a silver-copper alloy contact repressing machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a silver-copper alloy contact repressing machine, comprising a worktable and further comprising: a feeding mechanism movably mounted on the upper surface of the worktable; and a precision control mechanism fixedly mounted inside the feeding mechanism; wherein the feeding mechanism comprises a sliding plate slidably connected to the upper surface of the worktable, a connecting frame fixedly connected to the end of the sliding plate, a base fixedly connected to the arc-shaped inner surface of the connecting frame, the lower surface of the base fitting against the upper surface of the worktable, and a gathering tube fixedly connected to the upper edge surface of the base.

[0006] According to one embodiment of the present invention, the upper surface of the base is symmetrically provided with a material leakage groove, the end of the connecting frame away from the arc surface is fixedly connected to a mounting frame, the inner surface of the mounting frame is fixedly connected to a sliding rod, and a rack is elastically slidably connected to the sliding rod by a spring.

[0007] According to one embodiment of the present invention, a connecting block is fixedly connected to the side surface of the rack, and an electric telescopic rod is fixedly connected to the outer surface of the connecting block. The end of the electric telescopic rod away from the connecting block is fixedly connected to the workbench.

[0008] According to one embodiment of the present invention, a partition plate is fixedly connected inside the material leakage trough, wherein two partition plates are fixedly spaced in a single material leakage trough, and the single material leakage trough is divided into three cavities by the partition plates, wherein the cavities in the three material leakage troughs are cubic in shape.

[0009] According to one embodiment of the present invention, the outer surface of the collecting tube is rotatably connected to a transfer tube, and the bottom outer surface of the transfer tube is provided with a toothed groove, wherein the bottom of the transfer tube is configured as a semi-circular tube, and the toothed groove meshes with a toothed rack.

[0010] According to one embodiment of the present invention, an adapter frame is fixedly connected to the top inner surface of the adapter pipe, a rotating rod is fixedly connected through the middle upper surface of the adapter frame, and the bottom of the rotating rod is rotatably connected through the upper surface of the base.

[0011] According to one embodiment of the present invention, the base has a first mounting groove inside, and a limiting rod is symmetrically and fixedly connected to the bottom surface of the first mounting groove. A first baffle is slidably connected to the limiting rod. The first baffle is T-shaped, and two first baffles are symmetrically arranged in the first mounting groove. A first rotating ring is rotatably connected to the inner surface of the first baffle. The first rotating ring is fixedly sleeved on the outer surface of the rotating rod. The first baffle is initially positioned opposite the material leakage groove.

[0012] According to one embodiment of the present invention, the precision control mechanism includes a second mounting slot, which is opened inside the base and is located below the first mounting slot. A limit rod is symmetrically fixedly connected inside the second mounting slot. A second baffle is slidably connected to the limit rod inside the second mounting slot. The second baffle is L-shaped, and two baffles are arranged in opposite directions inside the second mounting slot. A second rotating ring is rotatably connected to the inner surface of the second baffle. The second rotating ring is fixedly sleeved on the bottom outer surface of the rotating rod. Initially, the second baffle is misaligned with the material leakage trough.

[0013] According to one embodiment of the present invention, a mounting rod is fixedly connected through the bottom outer surface of the rotating rod, and scrapers are fixedly sleeved at both ends of the mounting rod. The scrapers are arranged in an inclined shape, and the bottom surface of the scrapers is attached to the upper surface of the base.

[0014] First, move the entire device to the production line of the repress machine. Insert the spherical contact blank from the top of the collecting tube; the contact blank is temporarily stored in the collecting tube. Then, start the electric telescopic rod. The electric telescopic rod begins to push the connecting block forward, simultaneously driving the rack to move. Due to the large elastic force of the rack on the slide rod, initially the rack, along with the connecting frame and sliding plate, moves forward as a whole. Then, controlled by the start of the electric telescopic rod, the base and collecting tube, fixedly connected to the connecting frame, begin to move closer to the mold on the production line. Finally, the base moves directly above the mold, and the bottom surface of the base is in contact with the upper surface of the lower mold. At this point, the sliding plate moves to its maximum value and cannot move further. As the electric telescopic rod continues to work, it begins to drive the rack to slide along the slide rod. The elastic force of the rack is compressed. When the rack rotates, it drives the adapter pipe to rotate through meshing. The rotation of the adapter pipe then drives the adapter frame and rotating rod to move forward. The rotating rod rotates, which in turn drives the first rotating ring to rotate. Under the action of rotation, the two symmetrically arranged first baffles begin to move in opposite directions. Eventually, the first baffles are misaligned with the material discharge trough. At this time, the spherical contact blanks in the collecting tube enter the material discharge trough and are separated by partition plates. The cavity between the two partition plates can only accommodate one contact blank at a time, so that the contact blanks can enter the mold cavity of the lower mold through the material discharge trough for filling. At this time, the reverse braking electric telescopic rod, that is, under the action of elasticity, the rack begins to reset first, thereby driving the first baffle to reset and close the material discharge trough again. After the material discharge trough is closed again, the rack reset is completed. As the electric telescopic rod continues to work, it begins to drive the base to move away from the mold and reset. After the equipment moves out of the mold, it begins to re-press and shape the contact blanks in the mold, finally forming a cylindrical molded contact.

[0015] This invention provides a feeding device for a silver-copper alloy contact repressing machine. It has the following beneficial effects: (i) The feeding device of this silver-copper alloy contact repressing machine can automatically complete the feeding operation of the contact blank through the set feeding mechanism, avoiding the problem of low production efficiency caused by the frequent use of manual filling in traditional equipment, and also greatly improving production safety. In addition, this equipment is an independent structure and can be matched with different production lines, which greatly improves the applicability of this equipment.

[0016] (II) The feeding device of this silver-copper alloy contact repressing machine initially closes the material chute during the feeding process, and the second baffle at the bottom is staggered with the material chute, meaning the bottom of the material chute is initially open. When the base reaches the designated position, the first baffle opens the material chute first, and the second baffle simultaneously closes the bottom of the material chute. At this time, the contact blank is temporarily stored in the material chute and blocked by the second baffle. When the electric telescopic rod reverses its operation, the first baffle closes the material chute again, and the second baffle gradually opens the material chute. Finally, when the first baffle closes the material chute, the contact blank falls through the bottom of the material chute into the mold. This ensures that the material chute can only be opened on one side at a time, and the contact blank is only put into the mold after preparation. This greatly improves the automated continuous production efficiency of the equipment, avoids the problem of excessive contact blanks being put into the mold at one time when the material chute is open, and also greatly improves the protection of the equipment.

[0017] (III) The feeding device of this silver-copper alloy contact repressing machine will drive the mounting rod to rotate synchronously when the rotating rod rotates, that is, drive the hanging plate to rotate. This will ensure that the upper part of the material discharge trough is stirred by the scraper before each contact blank enters the material discharge trough, thereby ensuring that each cavity in the material discharge trough can be quickly filled with the contact blank. This avoids the problem of the contact blank not being able to enter the material discharge trough smoothly due to the stacking of the contact blank in the collection tube, and greatly improves the working stability of this equipment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a feeding device for a silver-copper alloy contact repressing machine, comprising a worktable 1, and further comprising: Feeding mechanism 2 is movably installed on the upper surface of workbench 1; Precision control mechanism 3 is fixedly installed inside the feeding mechanism 2; The feeding mechanism 2 includes a sliding plate 21, which is slidably connected to the upper surface of the workbench 1.

The lower surface of the base 23 is attached to the upper surface of the workbench 1. A gathering tube 24 is fixedly connected to the upper edge of the base 23.

[0022] The upper surface of the base 23 is symmetrically provided with a material discharge groove 25. The end of the connecting frame 22 away from the arc surface is fixedly connected to the mounting frame 26. The inner surface of the mounting frame 26 is fixedly connected to the slide rod 27. The slide rod 27 is elastically slidably connected to the rack 28 by a spring.

[0023] A connecting block 29 is fixedly connected to the side surface of the rack 28, and an electric telescopic rod 210 is fixedly connected to the outer surface of the connecting block 29. The end of the electric telescopic rod 210 away from the connecting block 29 is fixedly connected to the workbench 1.

[0024] A partition plate 211 is fixedly connected inside the material leakage trough 25. There are two partition plates 211 with a fixed spacing in a single material leakage trough 25. The single material leakage trough 25 is divided into three cavities by the partition plates 211, and the cavities in the three material leakage troughs 25 are cubic in shape.

[0025] The outer surface of the collecting tube 24 is rotatably connected to the adapter tube 212. The bottom outer surface of the adapter tube 212 is provided with a toothed groove 213. The bottom of the adapter tube 212 is set as a semi-circular tube. The toothed groove 213 meshes with the rack 28.

[0026] The top inner surface of the adapter pipe 212 is fixedly connected to the adapter frame 214, the middle upper surface of the adapter frame 214 is fixedly connected to the rotating rod 215, and the bottom of the rotating rod 215 is rotatably connected to the upper surface of the base 23.

[0027] The base 23 has a first mounting slot 216 inside. The bottom surface of the first mounting slot 216 is symmetrically and fixedly connected to a limit rod 217. A first baffle 218 is slidably connected to the limit rod 217. The first baffle 218 is T-shaped. There are two first baffles 218 symmetrically arranged in the first mounting slot 216. A first rotating ring 219 is rotatably connected to the inner surface of the first baffle 218. The first rotating ring 219 is fixedly sleeved on the outer surface of the rotating rod 215. The first baffle 218 is initially set opposite to the material discharge trough 25.

[0028] Second embodiment: as follows Figures 1 to 8 As shown, the precision control mechanism 3 includes a second mounting slot 31, which is located inside the base 23 and below the first mounting slot 216. A limit rod 217 is symmetrically fixedly connected inside the second mounting slot 31. A second baffle 32 is slidably connected to the limit rod 217 inside the second mounting slot 31. The second baffle 32 is L-shaped and there are two baffles 32 arranged in opposite directions inside the second mounting slot 31. A second rotating ring 33 is rotatably connected to the inner surface of the second baffle 32. The second rotating ring 33 is fixedly sleeved on the bottom outer surface of the rotating rod 215. Initially, the second baffle 32 is misaligned with the material leakage trough 25.

[0029] A mounting rod 34 is fixedly connected through the bottom outer surface of the rotating rod 215. Scrapers 35 are fixedly sleeved at both ends of the mounting rod 34. The scrapers 35 are inclined and the bottom surface of the scrapers 35 is attached to the upper surface of the base 23.

[0030] During operation, the entire device is first moved to the production line of the repressing machine. The spherical contact blank is then inserted from the top of the collecting tube 24, temporarily storing the contact blank within it. Next, the electric telescopic rod 210 is activated, pushing the connecting block 29 forward, which simultaneously moves the rack 28. Due to the significant elasticity of the rack 28 on the slide rod 27, initially, the rack 28, along with the connecting frame 22 and the sliding plate 21, moves forward. Then, controlled by the activation of the electric telescopic rod 210, the base 23 and the collecting tube 24, fixedly connected to the connecting frame 22, begin to move closer to the mold on the production line. Finally, the base 23 moves directly above the mold, with its bottom surface touching the upper surface of the lower mold. At this point, the sliding plate 21 moves... When the electric telescopic rod 210 reaches its maximum displacement, it can no longer move. As the electric telescopic rod 210 continues to operate, it drives the rack 28 to slide along the slide rod 27. The elastic force of the rack 28 is compressed. When the rack 28 rotates, it drives the adapter pipe 212 to rotate through meshing. This rotation of the adapter pipe 212 then drives the adapter frame 214 and the rotating rod 215 to rotate. As the rotating rod 215 rotates, it simultaneously drives the first rotating ring 219 to rotate. Under this rotation, the two symmetrically arranged first baffles 218 begin to move in opposite directions. Finally, the first baffles 218 are misaligned with the discharge trough 25. At this point, the spherical contact blank in the collecting tube 24 enters the discharge trough 25 and is separated by the partition plate 211, cutting it into two parts. The cavity between the partitions 211 can only accommodate one contact blank at a time. Even if the contact blank enters the mold cavity of the lower mold through the material discharge channel 25 for filling, the reverse braking electric telescopic rod 210 will cause the rack 28 to reset first under the action of the elastic force, thereby driving the first baffle 218 to reset and close the material discharge channel 25 again. After the material discharge channel 25 is closed again, the rack 28 has completed its reset. As the electric telescopic rod 210 continues to work, it begins to drive the base 23 away from the mold and reset. After the equipment moves out of the mold, it begins to re-press and shape the contact blank in the mold, finally forming a cylindrical molded contact. The feeding mechanism 2 can automatically complete the feeding operation of the contact blank, avoiding the need for frequent feeding operations required by traditional equipment. This equipment overcomes the problem of low production efficiency caused by manual filling, while also significantly improving production safety. Furthermore, its independent structure allows it to be matched with different production lines, greatly enhancing its applicability. During the feeding process, the first baffle 218 initially closes the material discharge trough 25, and the second baffle 32 at the bottom is offset from the material discharge trough 25, meaning the bottom of the material discharge trough 25 is initially open. When the base 23 reaches the designated position, the first baffle 218 first opens the material discharge trough 25, and at this time, the second baffle 32 simultaneously closes the bottom of the material discharge trough 25. Thus, the contact blank is temporarily stored in the material discharge trough 25 and blocked by the second baffle 32. When the electric telescopic rod 210 reverses its operation, the first baffle 218 reopens the material discharge trough 25.Furthermore, the second baffle 32 gradually opens the material discharge trough 25. Finally, when the first baffle 218 closes the material discharge trough 25, the contact blank falls through the bottom of the trough 25 into the mold. This ensures that the material discharge trough 25 can only be opened from one end (top or bottom) at a time, allowing the contact blank to be placed into the mold only after preparation. This significantly improves the automated continuous production efficiency of the equipment and avoids the problem of excessive contact blanks being added at once when the material discharge trough 25 is open, which could lead to defective products. It also greatly enhances the protection of the equipment. When the rotating rod 215 rotates, it simultaneously drives the mounting rod 34 to rotate, which in turn drives the hanging plate to rotate. This ensures that before each contact blank enters the material discharge trough 25, the scraper 35 agitates the top of the trough 25, ensuring that each cavity in the trough 25 can be quickly filled with contact blanks. This prevents the contact blanks from piling up in the collecting tube 24, which could hinder their smooth entry into the material discharge trough 25, thus significantly improving the operational stability of the equipment.
