Description

Technical Field

[0001] This invention relates to the field of valve milling chip processing technology, and more particularly to an automatic valve milling machine. Background Technology

[0002] Milling machines are commonly used equipment in machining. When milling different parts of valves and other components, a large amount of metal material is removed and chips are generated. Since different parts of a valve are often made of different materials, various types of chips, such as cast iron chips, steel chips, and copper chips, are usually generated simultaneously during the machining process. These chips are mixed together and come into contact with the coolant used in the milling process.

[0003] Cast iron, steel, copper, and other metals are all valuable recyclable resources. If they can be recycled according to their material, their reuse value is high. However, in the current technology, the processing of milling chips mostly mixes various chips such as cast iron chips, steel chips, and copper chips together. Existing devices mostly use simple collection methods, which makes it difficult to achieve automatic classification according to material. This results in low sorting efficiency and low purity of recycled chips, which reduces the recycling value of metal resources. Summary of the Invention

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] For detailed implementation methods, please refer to... Figures 1-9 ,include, The milling machine body 100 includes a collection trough 101 within the milling machine body 100, two collection hoppers 102 fixed within the milling machine body 100, a collection tray 104 sliding within the collection hoppers 102, a guide assembly 200 fixed within the collection trough 101, a guide assembly 300 rotating within the guide assembly 200, a screening assembly 400 located within the collection hoppers 102, a reciprocating assembly 500 fixed to the bottom of the screening assembly 400, a cleaning assembly 600 fixed outside the guide assembly 200, and a conversion assembly 700 sleeved between the reciprocating assembly 500 and the guide assembly 300. The milling machine body 100... When different parts of the valve are machined, three types of mixed chips are generated: cast iron chips, steel chips, and copper chips. The steel chips are originally weakly magnetic or nearly non-magnetic, but after milling, they undergo a martensitic phase transformation (work hardening), thus acquiring weak magnetism and still being attracted by the magnetic roller. These three types of mixed chips fall onto the guide assembly 300 under the guidance of the guide assembly 200, relying on their own gravity. Since the guide assembly 300 itself has magnetic force, the magnetic cast iron chips and steel chips are attracted to its outer surface, while the non-magnetic copper chips cannot be attracted. The magnetic attraction achieves the initial separation of magnetic and non-magnetic metals, completing the initial classification of chips.

[0025] When the guide component 300 rotates to a certain extent, the copper chips that are not adsorbed fall into the first collection hopper 102 that passes through first. At the same time, the coolant used for milling is also discharged here. The first collection hopper 102 is equipped with a screening component 400, which can realize solid-liquid separation at the same time as the chips fall, separating the copper chips and coolant at one time. This design allows the chip falling and solid-liquid separation to be completed simultaneously, avoiding secondary processing caused by the mixing of chips and coolant, and significantly improving the separation efficiency.

[0026] As the guide component 300 continues to rotate, when the outer surface adsorbed with steel and cast iron chips moves to the position of the second collection hopper 102, the cleaning component 600 cleans the steel and cast iron chips adsorbed on its surface and removes them from the magnetic tube 301, allowing them to fall into the collection hopper 102 under the action of the guide component 200. In addition, during the rotation of the guide component 300, the reciprocating component 500 is synchronously driven by the conversion component 700, which in turn drives the screening component 400 to reciprocate, keeping the screening component 400 in a continuous shaking state, making it easier for the chips to fall off and be graded.

[0027] Since steel chips are long and thin while cast iron chips are irregularly shaped, the screening component 400 is equipped with screening holes that are adapted to these two different shapes. This allows steel chips and cast iron chips to fall precisely into their respective collection hoppers 102 through their appropriate holes. This device cleverly utilizes the difference in chip shape to achieve precise screening, resulting in more accurate classification and less mixing. Ultimately, it achieves automatic classification and recycling of three types of chips: cast iron chips, steel chips, and copper chips, significantly improving the purity and resource recycling value of the chips. Finally, the filtered coolant is transported back to the milling machine body 100 for reuse via the conversion component 700, reducing coolant consumption and waste discharge.

[0028] Furthermore, the guide assembly 200 includes a pair of guide plates 201 fixed to the top of the collection tank 101, a collection cylinder 202 fixed inside the collection tank 101, an opening 203 at the top of the collection cylinder 202, and a pair of guide plates 205 fixed to the outer surface of the collection cylinder 202. The guide plates 201 are inclined, the size of the opening formed between the pair of guide plates 201 corresponds to the opening 203 on the collection cylinder 202, and release ports 204 are provided on both sides below the outer surface of the collection cylinder 202. The guide assembly 300 includes a magnetic tube 301 rotating inside the collection cylinder 202, and multiple pairs of partitions 302 fixed to the outer surface of the magnetic tube 301. The size of the opening formed between adjacent sets of partitions 302 matches the diameter of the opening 203. When the milling machine body 100 processes different parts of the valve, it generates three mixed chips: cast iron chips, steel chips, and copper chips. These three mixed chips, relying on their own gravity, are guided by the pair of guide plates 201. Guided by the 5, the chips fall between adjacent partitions 302 on the outer surface of the magnetic tube 301. Due to the strong magnetic force of the magnetic tube 301, magnetic cast iron and steel chips are attracted to its outer surface, while non-magnetic copper chips cannot be attracted. The magnetic attraction achieves the initial separation of magnetic and non-magnetic metals, and the initial classification of chips can be completed without manual sorting. When the chips between adjacent partitions 302 on the outer surface of the magnetic tube 301 reach the first release port 204, the non-magnetic copper chips and coolant between adjacent partitions 302 on the outer surface of the magnetic tube 301 will enter the collection hopper 102 from this release port 204 along the guide plate 205. When the cast iron and steel chips attracted between adjacent partitions 302 on the outer surface of the magnetic tube 301 reach the release port 204 on the other side, the cleaning component 600 will clean the cast iron and steel chips attracted to the outer surface of the magnetic tube 301, thereby achieving the initial classification of chips and avoiding secondary processing caused by the mixing of chips and coolant.

[0029] Furthermore, the screening assembly 400 includes a folded screen plate 401 fixed in one collection hopper 102, an inclined screen plate 402 disposed in another collection hopper 102, and an isolation perforated plate 403 fixed in the middle of the inclined screen plate 402. The inclined screen plate 402, centered on the isolation perforated plate 403 and near the guide plate 205, has slotted holes 404 and circular holes 405 that match the holes on the isolation perforated plate 403. The top of the folded screen plate 401 is perforated, while the vertical portion is sealed. The inclined horizontal plate portion of the folded screen plate 401 serves as a filter plate, thus enabling the coolant to be filtered. The copper shavings are separated into solid and liquid components. The vertical part of the folded sieve plate 401 is sealed. When the copper shavings and coolant are discharged from the magnetic tube 301 and the collection cylinder 202, the coolant will permeate at the filter plate, while the copper shavings will roll down the inclined section into the collection hopper 102. In addition, steel shavings are long and thin, while cast iron shavings are irregularly shaped. The inclined sieve plate 402 is equipped with matching screening holes for these two different shapes, so that steel shavings and cast iron shavings can fall accurately into the corresponding collection hopper 102 at their respective suitable holes. By utilizing the difference in the shape of the chips, precise screening is achieved, resulting in more accurate classification and less mixing.

[0030] Furthermore, such as Figures 1-6 A sliding groove 103 is provided on the inner wall of the collection hopper 102 at the position of the inclined sieve plate 402; The reciprocating assembly 500 includes a baffle 501 fixed inside the collecting hopper 102, a connecting plate 502 sliding above the baffle 501, a ball 503 movable in the sliding groove 103, the ball 503 being fixedly connected to the inclined screen plate 402, a spring 504 disposed between the ball 503 and the sliding groove 103, an eccentric wheel 505 abutting against the bottom of the inclined screen plate 402, the eccentric wheel 505 being rotatably connected to the collecting hopper 102, the top of the connecting plate 502 being fixedly connected to the bottom of the inclined screen plate 402, and the ball (503) being fixedly connected to the inclined screen plate (402). Next, the cleaning component 600 includes a folded scraper 601 that contacts the outer surface of the magnetic tube 301, multiple notches 602 formed on the outside of the folded scraper 601, a support plate 603 rotatably connected to each of the multiple notches 602, and a spring 604 disposed between the support plate 603 and the folded scraper 601. The support plate 603 is fixedly connected to the collection cylinder 202. As the magnetic tube 301 rotates, when the outer surface adsorbed with steel chips and cast iron chips moves to the position of the second collection hopper 102, the end of the folded scraper 601 will scrape the steel chips and cast iron chips adsorbed on the outer surface of the magnetic tube 301. As the magnetic tube 301 continues to rotate, the partition plate 302 on its outer surface will abut against the folded scraper 601. The folded scraper 601 will rotate around the point where it connects to the support plate 603, and will be pushed upwards by the abutment. Simultaneously, the bottom end of the folded scraper 601 is hook-shaped, so the end of the folded scraper 601 will move from the outer surface of the magnetic tube 301 to the surface of the partition plate 302 for cleaning, scraping off steel and cast iron shavings, which will then fall onto the inclined screen plate 402 along the trajectory of the guide plate 205. Furthermore, during the rotation of the magnetic tube 301, the conversion assembly 70... The eccentric wheel 505 is driven to rotate synchronously, and then the eccentric wheel 505 abuts against the bottom of the inclined screen plate 402, so that the ball 503 of the inclined screen plate 402 moves back and forth in the sliding groove 103, so that the inclined screen plate 402 can be continuously vibrating. At this time, the cast iron chips and steel chips will fall into the collection hopper 102 through the designed holes under vibration. The screen plate is an elastic screen plate instead of a metal screen. For example, the hole wall of the rubber screen plate will elastically expand and contract when vibrating, which will prevent the chips from clogging the holes. This is very common in the industry, thus completing the classification between steel chips and cast iron chips.

[0031] Furthermore, the conversion assembly 700 includes shafts 701 fixedly connected to the magnetic tube 301 and the eccentric wheel 505 respectively. A belt 702 is fitted on the outer surface of the two shafts 701. The bottom side of the collection hopper 102 with the folded screen plate 401 inside is connected to a connecting pipe 703. A pump body 704 is installed outside the connecting pipe 703. The connecting pipe 703 is connected to the milling machine body 100 through the pump body 704. The belt 702 and the shafts 701 connect the power of the magnetic tube 301 with the power of the eccentric wheel 505. The end of the shaft 701 is connected to an external drive source such as a servo motor. The filtered coolant will be input into the milling machine body 100 for circulation through the connecting pipe 703 under the action of the pump body 704.

[0032] Working Principle: When the milling machine body 100 processes different parts of the valve, it generates three types of mixed chips: cast iron chips, steel chips, and copper chips. These chips, guided by their own gravity and a pair of V-shaped guide plates 205 on the outer surface of the collecting cylinder 202, fall between adjacent partitions 302 on the outer surface of the magnetic tube 301 inside the collecting cylinder 202. Because the magnetic tube 301 has strong magnetic force, the magnetic cast iron and steel chips are attracted to its outer surface, while the non-magnetic copper chips cannot be attracted, thus achieving initial separation of magnetic and non-magnetic metals. As the magnetic tube 301 rotates, when the chips between adjacent partitions 302 reach the first release point... When the discharge port 204 is opened, the copper shavings that are not adsorbed and the coolant fall from the discharge port 204 along the guide plate 205 into the collection hopper 102. Before entering the collection hopper 102, the folded sieve plate 401, because its inclined horizontal plate part is a filter plate and its vertical part is sealed, allows the coolant to achieve solid-liquid separation by permeating down at the filter plate position. The copper shavings roll down the inclined surface into the collection hopper 102. When the cast iron shavings and steel shavings adsorbed on the outer surface of the magnetic tube 301 turn to the other side of the discharge port 204, the end of the folded scraper 601 will scrape the steel shavings and cast iron shavings adsorbed on the outer surface of the magnetic tube 301. When the magnetic tube 301 continues to rotate, the partition plate 302 on its outer surface will fold in half. The folded scraper 601 is pressed against the magnetic tube 301, causing it to rotate around the point where it connects to the support plate 603. The scraper 601 is then pressed upwards, and its hook-shaped bottom end allows it to move from the outer surface of the magnetic tube 301 to the surface of the partition plate 302 for cleaning, scraping off steel and cast iron filings. These filings then fall onto the inclined screen plate 402 along the guide plate 205. Furthermore, during the rotation of the magnetic tube 301, the eccentric wheel 505 is synchronously driven to rotate via the conversion component 700, causing the eccentric wheel 505 to press against the bottom of the inclined screen plate 402. The sphere 503 of the inclined screen plate 402 reciprocates within the sliding groove 103, allowing the inclined screen plate 402 to continuously vibrate. One type of steel chip, in the shape of a long strip, and the other type of cast iron chip, in the shape of irregular granules, fall onto the inclined screen plate 402. The inclined screen plate 402 has a central isolation perforated plate 403 as its center, with a strip hole 404 on one side and a round hole 405 on the other side. This allows the two types of chips to fall precisely into their respective collection hoppers 102 through their matching holes, achieving precise sieving based on their shape differences. The filtered coolant will be pumped into the milling machine body 100 through the connecting pipe 703 by the pump body 704 for recycling.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
