Technical Field
[0001] This utility model relates to the field of vertical ring rolling mill technology, and in particular to a slag removal mechanism for a vertical ring rolling mill. Background Technology
[0002] A vertical ring rolling mill is a device used for cold forming of ring-shaped workpieces. It is widely used in the manufacturing of bearings, gears, and automotive parts. The device applies pressure to the workpiece through rolling rollers to achieve a predetermined size and surface shape, thus realizing efficient and accurate forming. During the ring rolling process, a certain amount of metal shavings and oxide residues will be generated on the surface of the workpiece. If these residues are not removed in time, they will affect subsequent processes and the quality of the finished product. Therefore, equipping the workpiece with an effective slag removal mechanism is an important part of ensuring the smooth progress of the ring rolling process.
[0003] Existing slag removal mechanisms for ring rolling mills mostly employ a single contact scraping structure, relying on direct contact between the scraper and the workpiece surface to remove residue. This lack of airflow-assisted slag removal design results in incomplete cleaning of highly adhesive or difficult-to-scrape oxide scale and metal shavings, affecting the surface quality of the rolled ring workpiece. Furthermore, existing slag removal mechanisms generally lack a quick-release collection device, making the cleaning and maintenance of the residue collection frame cumbersome. It requires manual disassembly and resetting, increasing operational difficulty and downtime, and reducing work efficiency.
[0004] Therefore, in response to the problems existing in the slag removal mechanism of the current ring rolling mill, this utility model improves the cleaning efficiency of oxide scale and metal shavings that are highly adhesive or difficult to scrape off by setting up a scraper plate and a nozzle that fits into the surface of the workpiece to be rolled. The scraper plate continuously scrapes off the residue, and the high-pressure gas sprayed from the nozzle helps to blow off the residue on the surface of the workpiece. The automatic pop-out and limiting structure of the collection frame composed of a storage spring, push plate, hook and buckle is adopted to realize the quick assembly and disassembly of residue collection and cleaning, thereby improving the cleanliness and work efficiency of the ring rolling process. Utility Model Content
[0005] To overcome the problems of existing ring rolling mill slag removal mechanisms that mainly rely on scraper blades to contact the workpiece to remove residues, lack airflow assistance, make it difficult to thoroughly clean stubborn oxide scale and metal shavings, affecting the surface quality of the workpiece, and at the same time, the collection frame lacks a quick pop-out function, making cleaning and maintenance cumbersome, increasing the difficulty of operation and downtime, and reducing work efficiency.
[0006] The technical solution of this utility model is as follows: a slag removal mechanism for a vertical ring rolling mill, comprising a base, an outer frame, and a connecting ring; the bottom of the base is fixedly connected to a support foot, which is symmetrically installed at the four corners of the bottom of the base; the top of the base is fixedly connected to a support, which is located near the back of the base; the outer frame is fixedly connected to the top of the base; a dust baffle is fixedly connected to the side of the outer frame away from the base; the outer frame and the dust baffle are fixedly connected to the front of the support, which is located near the bottom of the support; and the connecting ring is fixedly connected to the front of the support.
[0007] Preferably, the support legs are made of polyethylene, the outer frame and the dust baffle are an integrated structure, and the connecting rings are symmetrically installed near the two sides of the support.
[0008] Preferably, the support has a connecting seat and a fixing ring fixedly connected to its front side, an air supply pipe fixedly connected to the inner side wall of the connecting seat, the fixing ring being located near the connecting seat, and a nozzle fixedly connected to the inner side wall of the fixing ring, the nozzle being fixedly connected to the end of the air supply pipe near the fixing ring.
[0009] Preferably, a placement rod is fixedly connected to the front of the support, the placement rod is located near the center of the support, the connecting ring is located near the placement rod, and a ring rolling wheel and an auxiliary wheel are provided on the front of the support. The ring rolling wheel is located near the nozzle, and the auxiliary wheels are symmetrically installed near the placement rod.
[0010] Preferably, a collection frame is slidably connected inside the outer frame, and a push plate is fixedly connected to the bottom of the collection frame. The push plates are symmetrically installed near both sides of the collection frame and slidably connected inside the outer frame. A storage spring is movably connected to the side of the push plate near the support, and the end of the storage spring away from the push plate is fixedly connected to the front of the support.
[0011] Preferably, the outer frame is rotatably connected to a hook, which is engaged with the bottom of the collection box. The end of the hook away from the collection box is fixedly connected to a buckle, which is engaged with the front of the outer frame. The buckle is made of spring steel. A return spring is fixedly connected to the bottom of the hook, which is located near the collection box. The end of the return spring away from the hook is fixedly connected to the inside of the outer frame.
[0012] Preferably, a sleeve is fixedly connected to the inner wall of the connecting ring, a limit rod is slidably connected inside the sleeve, a stabilizing spring is sleeved on the outer side of the limit rod, a scraper is fixedly connected to the end of the limit rod away from the sleeve, the scraper is slidably connected to the front of the support, one end of the stabilizing spring is fixedly connected to the end of the sleeve near the scraper, and the other end of the stabilizing spring is fixedly connected to the end of the scraper near the limit rod.
[0013] The beneficial effects of this utility model are:
[0014] During the ring rolling process of the device, the annular area of the workpiece to be rolled gradually expands and comes into contact with the scraper plate. The stabilizing spring keeps the scraper plate in contact with the workpiece surface and continuously scrapes off the surface residue. At the same time, the nozzle sprays high-pressure cleaning gas to help blow off or loosen the residue on the workpiece surface. The residue scraped off by the scraper plate falls directly into the collection frame, while the residue blown off by the nozzle is guided by the airflow to the dust baffle plate and then enters the collection frame, completing the ring rolling slag removal operation. This realizes the design of the airflow-assisted slag removal mechanism, which improves the cleaning efficiency of oxide scale and metal shavings that are highly adhesive or difficult to scrape off.
[0015] When the device needs to clean the residue in the collection box, pull out the buckle, which will cause the hook to release from the locking limit of the collection box. The stored spring will push the push plate and the collection box to move outward, pushing the collection box out of the outer frame. This will enable the collection box to pop out automatically and quickly, making it easy to remove and clean the residue, simplifying the operation process, reducing downtime, and thus improving work efficiency.
[0016] When the device needs to be returned to the collection frame, insert the collection frame and push plate into the outer frame. When the collection frame reaches its deepest point, the reset spring drives the hook to rotate to the bottom position of the collection frame. At this time, the buckle is inserted into the outer frame, and the hook is then inserted into the bottom of the collection frame to complete the limit engagement and ensure that the collection frame is reset in place.

The housing 601 is fixed to the inner wall of the connecting ring 6 and has a limiting rod 602 inside, so that the scraper 604 can achieve stable sliding adjustment on the front of the support 3.
[0032] Working principle: According to Figures 1 to 3As shown, when using this device, first, place the device in the work area. The polyethylene support legs 2 provide stable support for the base 1 and support 3. Then, put the workpiece to be rolled into a ring on the placement rod 305. Start the rolling wheel 306 with an external power source to roll the workpiece into a ring. The auxiliary wheel 307 protects and limits the workpiece during this process, thus completing the rolling preparation.
[0033] according to Figures 1 to 6 As shown, during the ring rolling process of the device, the ring area of the workpiece to be rolled gradually expands under the action of the rolling wheel 306 until it contacts the scraper plate 604. At this time, under the elastic force of the stabilizing spring 603, the scraper plate 604 is kept in contact with the surface of the workpiece and continuously scrapes off the surface residue. The limiting rod 602 slides back and forth with the scraper plate 604 in the housing 601 to ensure the stability of the stabilizing spring 603 and the scraper plate 604 and prevent shaking. At the same time, the external air source is delivered to the nozzle 304 through the air supply pipe 302 on the connecting seat 301. The nozzle 304 sprays high-pressure cleaning gas to help blow off or loosen the residue on the surface of the workpiece. The residue scraped off by the scraper plate 604 falls directly into the collection frame 401 under the action of gravity. The residue blown off by the nozzle 304 is guided by the airflow to the dust baffle 5 and then enters the collection frame 401 with gravity, completing the ring rolling slag removal operation.
[0034] according to Figures 4 to 5 As shown, when the device needs to clean the residue in the collection frame 401, first, pinch the buckle 405, apply force to overcome the elastic force of the return spring 406, pull out the buckle 405, and drive the hook 404 to release the engagement limit with the collection frame 401. At this time, the storage spring 403 releases its elastic force, pushes the push plate 402 and the collection frame 401 to move outward, push the collection frame 401 out of the outer frame 4, realize the automatic pop-out of the collection frame 401, and make it easy to remove and clean the residue.
[0035] according to Figures 4 to 5 When the device needs to be returned to the collection frame 401, first, align the collection frame 401 and the push plate 402 with the outer frame 4, and apply force to insert and push it in. The energy storage spring 403 is compressed and stores energy. When the collection frame 401 reaches the deepest point, under the elastic force of the reset spring 406, the hook 404 is rotated to the bottom position of the collection frame 401. At this time, pinch and pull the buckle 405 to insert the buckle 405 into the outer frame 4. The hook 404 is then inserted into the bottom of the collection frame 401 to complete the limiting engagement and ensure that the collection frame 401 is reset in place.
