Abstract
Description
Technical Field
[0001] This invention relates to the field of rolling, specifically to a rolling equipment for small-diameter copper strip springs. Background Technology
[0002] In the fields of electronics, precision machinery, and automotive parts, small-diameter copper strip springs are widely used in key components such as connectors, sensors, and elastic contacts due to their excellent conductivity, ductility, and elasticity. As downstream industries continuously increase their requirements for product precision and reliability, higher standards are being set for the rolling quality of small-diameter copper strip springs. Not only are dimensional tolerances required to be controlled within the micrometer level, but surface finish must also be guaranteed to prevent performance degradation due to impurities adhering during the rolling process. Traditional copper strip rolling equipment suffers from two main problems when processing small-diameter springs: First, the pressure rollers are not cleaned promptly. During rolling, oxide layers, metal debris, and rolling oil residues on the copper strip surface easily adhere to the pressure rollers. With each rolling pass, these impurities accumulate on the pressure roller surface, leaving indentations or scratches on the surface of subsequently rolled copper strips, severely affecting product yield. Second, waste collection efficiency is low. Copper shavings and waste generated during rolling are mostly scattered, resulting in low utilization of the collection box space and requiring frequent shutdowns for cleaning. This not only affects production continuity but also increases labor costs. Summary of the Invention
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this invention provides a rolling equipment for small-sized copper strip springs. The equipment can efficiently clean the pressure rollers and collect and compact waste materials while rolling copper strip springs, ensuring rolling quality and a clean working environment, thus solving the problems mentioned in the background technology.
[0005] (II) Technical Solution
[0006] To achieve the goal of efficiently cleaning the pressure rollers and collecting and compacting waste materials while rolling copper strip springs, thus ensuring rolling quality and a clean working environment, the present invention provides the following technical solution: A rolling device for small-specification copper strip springs, comprising a base, a support mounted on the base, a pressure roller rotatably mounted on the support, a protective plate mounted on the support, a cleaning structure mounted on the protective plate, the cleaning structure including a scraper mounted on the protective plate, the scraper abutting against the pressure roller, a connecting rod rotatably mounted on the protective plate, a lead screw lever mounted on the connecting rod, and a lead screw nut mounted on the lead screw lever. A cleaning plate is provided on the lead screw nut, with one end of the cleaning plate abutting against the pressure roller and the other end abutting against the scraper. A collection box is provided on the protective plate, abutting against the pressure roller, and a compaction structure is provided on the collection box. During the rolling process, the bracket on the base provides stable support for the pressure roller. The rotation of the pressure roller performs rolling operations on the copper strip spring. At this time, the cleaning structure on the protective plate begins to function. The scraper abuts against the pressure roller, which can initially scrape off impurities or copper shavings attached to the surface of the pressure roller. At the same time, the rotation of the pressure roller drives the second pulley to rotate, and the power is transmitted through the belt, causing the first pulley to drive the connecting rod to rotate, thereby causing the lead screw lever to rotate. The lead screw nut on the lead screw lever is displaced when the lead screw lever rotates. Since the cleaning plate is connected to the lead screw nut and is slidably mounted on the limit rod, the limit rod restricts the rotational freedom of the cleaning plate, allowing it to only move linearly along the limit rod. One end of the cleaning plate abuts against the pressure roller, and the other end abuts against the scraper. During the movement, it can further clean the surface of the pressure roller and push the impurities scraped off by the scraper towards the contact area between the scraper and the cleaning plate, facilitating subsequent collection. The impurities or copper shavings cleaned by the cleaning structure fall into the collection box that abuts against the pressure roller. The compaction structure on the collection box is activated simultaneously. The rotation of the pressure roller drives the cam to rotate. The cam abuts against the moving plate. When the cam's convexity... When the cam partially contacts the moving plate, it pushes the moving plate to slide along the guide rod towards the collection box. The moving plate, through the connecting plate, drives the compaction plate to move into the collection box, squeezing and compacting the waste material inside. When the cam's protrusion leaves the moving plate, the spring on the guide rod generates a restoring force due to the previous compression, pulling the moving plate to slide in the opposite direction, causing the compaction plate to return to its initial position. This process is repeated, and the compaction plate continuously compacts the waste material inside the collection box, reducing the space occupied by the waste material and improving the collection box's capacity. Through the coordinated actions of each structure, the equipment efficiently completes the cleaning of the pressure rollers and the collection and compaction of waste material while simultaneously rolling the copper strip spring sheet, ensuring rolling quality and a clean working environment.
[0007] Furthermore, a limit rod is provided on the protective plate, and the cleaning plate is slidably mounted on the limit rod.
[0008] Furthermore, a first pulley is provided on the connecting rod, and a second pulley is provided on the pressure roller. The first pulley is connected to the second pulley via a belt.
[0009] Furthermore, both the scraper and the cleaning plate are made of rubber.
[0010] Furthermore, the compaction structure includes a movable plate slidably disposed on the collection box, a connecting plate disposed on the movable plate, one end of the connecting plate extending into the interior of the collection box and connected to a compaction plate, and a cam rotatably disposed on the pressure roller, the cam abutting against the movable plate.
[0011] Furthermore, the collection box is provided with a guide rod, and the movable plate is slidably mounted on the guide rod.
[0012] Furthermore, a spring is provided on the guide rod, with one end of the spring connected to the movable plate and the other end connected to the collection box.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a rolling device for small-sized copper strip springs, which has the following beneficial effects: During the rolling process, the support on the base provides stable support for the pressure roller. The pressure roller rotates to perform rolling operations on the copper strip springs. At this time, the cleaning structure on the protective plate begins to function. The scraper contacts the pressure roller and can initially scrape off impurities or copper shavings attached to the surface of the pressure roller. At the same time, the rotation of the pressure roller drives the second pulley to rotate, and the power is transmitted through the belt, causing the first pulley to drive the connecting rod to rotate, which in turn causes the lead lever to rotate. The lead screw nut on the lead lever is displaced when the lead lever rotates. Since the cleaning plate is connected to the lead screw nut and is slidably set on the limit rod, the limit rod restricts the rotational freedom of the cleaning plate, so that it can only move in a straight line along the limit rod. One end of the cleaning plate contacts the pressure roller, and the other end contacts the scraper. During the movement, it can further clean the surface of the pressure roller and push the impurities scraped off by the scraper towards the scraper and the cleaning plate. The contact area of the plate facilitates subsequent collection. Impurities or copper shavings cleaned by the cleaning structure fall into the collection box that abuts against the pressure roller. The compaction structure on the collection box starts simultaneously. The rotation of the pressure roller drives the cam to rotate. The cam abuts against the moving plate. When the protruding part of the cam contacts the moving plate, it pushes the moving plate to slide along the guide rod towards the collection box. The moving plate drives the compaction plate to move into the collection box through the connecting plate, squeezing and compacting the waste in the box. When the protruding part of the cam leaves the moving plate, the spring on the guide rod generates a restoring force due to the previous compression, pulling the moving plate to slide in the opposite direction, so that the compaction plate returns to the initial position. This process is repeated, and the compaction plate continuously compacts the waste in the collection box, reducing the space occupied by waste and improving the capacity efficiency of the collection box. Through the coordinated action of each structure, the equipment can efficiently complete the cleaning of the pressure roller and the collection and compaction of waste while realizing the rolling of copper strip spring sheets, ensuring the rolling quality and the cleanliness of the working environment.

[0023] 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.
[0024] Example 1
[0025] A preferred embodiment of the rolling equipment for small-diameter copper strip springs provided by the present invention is as follows: Figures 1 to 7 The diagram shows a rolling mill for small-diameter copper strip springs, comprising a base 1, a support 2 mounted on the base 1, a pressure roller 3 rotatably mounted on the support 2, a protective plate 4 mounted on the support 2, and a cleaning structure 5 mounted on the protective plate 4. The cleaning structure 5 includes a scraper 501 mounted on the protective plate 4, the scraper 501 abutting against the pressure roller 3. A connecting rod 508 rotatably mounted on the protective plate 4, a lead lever 502 mounted on the connecting rod 508, a lead screw nut mounted on the lead lever 502, and a cleaning plate 504 mounted on the lead screw nut. One end of the cleaning plate 504 abuts against the pressure roller 3, and the other end abuts against the scraper 501. A collection box 6 is mounted on the protective plate 4, the collection box 6 abutting against the pressure roller 3, and a compaction structure 7 is mounted on the collection box 6.
[0026] Working principle: During the rolling process, the support 2 on the base 1 provides stable support for the pressure roller 3. The pressure roller 3 rotates to roll the copper strip spring. At this time, the cleaning structure 5 on the protective plate 4 begins to function. The scraper 501 contacts the pressure roller 3, which can initially scrape off the impurities or copper shavings attached to the surface of the pressure roller 3. At the same time, the rotation of the pressure roller 3 drives the second pulley 507 to rotate, and the power is transmitted through the belt 506, causing the first pulley 505 to drive the connecting rod 508 to rotate, which in turn causes the wire lever 502 to rotate. The wire on the wire lever 502... When the lead screw nut rotates, it generates displacement. Since the cleaning plate 504 is connected to the lead screw nut and slidably mounted on the limiting rod 503, the limiting rod 503 restricts the rotational freedom of the cleaning plate 504, allowing it to move only in a straight line along the limiting rod 503. One end of the cleaning plate 504 abuts against the pressure roller 3, and the other end abuts against the scraper 501. During the movement, it can further clean the surface of the pressure roller 3 and push the impurities scraped off by the scraper 501 towards the contact area between the scraper 501 and the cleaning plate 504, facilitating subsequent collection. Impurities or copper shavings removed by the cleaning structure 5 fall into the collection box 6, which is in contact with the pressure roller 3. The compaction structure 7 on the collection box 6 is activated simultaneously. The rotation of the pressure roller 3 drives the cam 701 to rotate. The cam 701 contacts the moving plate 703. When the protruding part of the cam 701 contacts the moving plate 703, it pushes the moving plate 703 to slide along the guide rod 702 towards the collection box 6. The moving plate 703, through the connecting plate 705, drives the compaction plate 706 to move into the collection box 6, squeezing and compacting the waste material inside. When the cam 701... When the protrusion of 01 leaves the moving plate 703, the spring 704 on the guide rod 702 generates a restoring force due to the previous compression, pulling the moving plate 703 to slide in the opposite direction, so that the compaction plate 706 returns to the initial position. This process is repeated, and the compaction plate 706 continuously compacts the waste in the collection box 6, reducing the space occupied by the waste and improving the capacity efficiency of the collection box. Through the continuous action of each structure, the equipment can efficiently complete the cleaning of the pressure roller and the collection and compaction of waste while realizing the rolling of copper strip spring sheets, ensuring the rolling quality and the cleanliness of the working environment.
[0027] In a preferred embodiment of the present invention, a limiting rod 503 is provided on the protective plate 4, and the cleaning plate 504 is slidably disposed on the limiting rod 503. This is so that the limiting rod 503 restricts the rotation of the cleaning plate 504, allowing it to slide linearly along the axial direction of the limiting rod 503, thereby preventing the cleaning plate 504 from shifting or wobbling as the wire lever rotates, ensuring that the cleaning plate 504 always maintains contact with the pressure roller 3 along a stable trajectory, and guaranteeing the uniformity of the cleaning effect.
[0028] In a preferred embodiment of the present invention, a first pulley 505 is provided on the connecting rod 508, and a second pulley 507 is provided on the pressure roller 3. The first pulley 505 is connected to the second pulley 507 via a belt 506. This is so that the belt 506 drives the rotation of the connecting rod 508 to keep the rotation of the pressure roller 3 linked. When the pressure roller 3 is working, the movement of the cleaning plate 504 is also started. When the pressure roller 3 stops, the cleaning plate 504 also stops moving accordingly. This ensures that the working rhythm of the cleaning structure 5 is completely matched with the rolling process, avoids the cleaning action being delayed or advanced, and can promptly clean the impurities generated on the surface of the pressure roller 3 during rolling, ensuring stable rolling quality.
[0029] In a preferred embodiment of the present invention, both the scraper 501 and the cleaning plate 504 are made of rubber. This is because rubber is soft and elastic, and when it comes into contact with the metal pressure roller 3, it can conform to the surface of the pressure roller through its own deformation. This will not scratch the rolling working surface of the pressure roller 3, nor will it cause scratches or deformation of the pressure roller 3 due to hard collision, thus effectively protecting the precision of the pressure roller 3.
[0030] In a preferred embodiment of the present invention, the compaction structure 7 includes a movable plate 703 slidably disposed on the collection box 6, a connecting plate 705 disposed on the movable plate 703, one end of the connecting plate 705 extending into the interior of the collection box 6 and connected to a compaction plate 706, and a cam 701 rotatably disposed on the pressure roller 3, the cam 701 abutting against the movable plate 703. When the pressure roller 3 is working, the cam 701 rotates synchronously and abuts against the movable plate 703, and the compaction plate 706 is immediately driven to move within the collection box 6 through the connecting plate 705, realizing real-time linkage between rolling operation and waste compaction, avoiding action delay between the two. At the same time, this design does not require a separate motor or other drive device for the compaction function, which not only simplifies the power system of the equipment, but also reduces energy consumption, making the equipment more efficient and energy-saving.
[0031] In a preferred embodiment of the present invention, a guide rod 702 is provided on the collection box 6, and the movable plate 703 is slidably disposed on the guide rod 702. This is because the guide rod 702 provides a clear path for the sliding of the movable plate 703, restricting the displacement of the movable plate 703 in directions other than the horizontal direction, ensuring that the movable plate 703 can only make reciprocating linear motion along the axial direction of the guide rod 702, avoiding the movable plate 703 from deviating, tilting or jamming under the push of the cam 701, and ensuring that the movement trajectory of the compaction plate 706 in the collection box 6 is stable, thereby uniformly compacting the waste.
[0032] In a preferred embodiment of the present invention, a spring 704 is provided on the guide rod 702. One end of the spring 704 is connected to the moving plate 703, and the other end is connected to the collection box 6. This is because when the cam 701 pushes the moving plate 703, the spring 704 is compressed and stores elastic potential energy. The deformation buffers the instantaneous impact force of the cam 701 on the moving plate 703, reduces the hard collision between the moving plate 703, the connecting plate 705, the compaction plate 706 and the collection box 6, reduces the wear rate of the components, and extends the overall service life of the compaction structure 7.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
