Description

Technical Field

[0001] The invention belongs to the technical field of centrifugal classification of dirt in cold heading machine discharge, and in particular relates to a discharge mechanism of a cold heading machine for small metal parts. Background Art

[0002] When the cold heading machine is discharging, the plate-shaped metal parts slide naturally through the inclined guide plate. During the sliding process, the plate-shaped metal parts are easily discharged quickly, resulting in the lubricating oil on the surface not being cleaned in time. Generally, the oil is cleaned by natural flow. When the falling speed is fast, the oil flow time is short, and it is not easy to clean thoroughly. In addition, the oil contains certain metal debris. Therefore, when the metal debris blocks the filter, it will cause the oil to float up and fill the plate-shaped metal parts with oil again, resulting in the need for manual cleaning in the later stage, which is a more complicated operation.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention. Example

[0040] like Figures 1 to 9As shown, a discharge mechanism of a cold heading machine for small metal parts includes a cold heading machine body 500 and a conveying unit 100, a driving unit 200, a centrifugal impurity removal unit 300 and a cleaning unit 400 installed at a discharge port.

[0041] The transport unit 100 includes a transport frame 101. Several pairs of positioning rods 1011 are installed on one side of the transport frame 101. Several pairs of turntables 102 are movably installed on the other side of the transport frame 101. Two feed rods 1021 are horizontally installed on each pair of turntables 102. The two feed rods 1021 are respectively placed on both sides of the corresponding positioning rod 1011. Plate-shaped metal parts 600 are installed on the feed rods 1021 and the positioning rods 1011. A collection box 1012 is connected to the bottom of the transport frame 101, and a filter screen 1032 is installed on the collection box 1012.

[0042] The driving unit 200 includes a driving motor 201 and a transmission shaft 203. The output shaft of the driving motor 201 is equipped with a rotating shaft 2011. The end of the rotating shaft 2011 is equipped with a driving bevel gear 2012. The rotating shaft 2011 is also equipped with a driving pulley 202. A plurality of worms 2031 are provided on the transmission shaft 203, and each worm 2031 is meshed with a worm wheel 2032. The rotation center of each worm wheel 2032 is fixedly connected to the rotation center of the corresponding turntable 102. A driven pulley 2022 is also installed on the transmission shaft 203. The driving pulley 202 and the driven pulley 2022 are connected by a belt 2021. After the parts slide into the conveying unit, the driving motor and the belt drive the worm and the worm wheel to rotate synchronously, and then drive the turntable and the feed rod to rotate synchronously. The feed rods on different turntables rotate synchronously, which can lift the plate metal parts and move them to the right until they move to the next workstation, and continue to drive the lifted plate metal parts to continue to move through the turntable. In the above operation, the feeding unit is in a horizontal state as a whole, which prevents the plate metal parts from sliding automatically, and they are transported step by step through the feed rod, which increases the sedimentation time of the oil on the parts, improves the cleaning effect, and impurities in the oil can also be blocked by the filter.

[0043] The centrifugal impurity removal unit 300 includes a splash-proof barrel 302, a centrifugal barrel 303 is rotatably arranged inside the splash-proof barrel 302, a leakage hole 3031 is opened on the centrifugal barrel 303, and a driven bevel gear 3033 is installed on the side wall of the centrifugal barrel 303, and the driven bevel gear 3033 and the driving bevel gear 2012 are engaged with each other; when the plate-like metal parts move into the centrifugal barrel, the rotating shaft at this time drives the centrifugal barrel to rotate through the engagement of the two bevel gears, and the oil attached to the plate-like metal parts is thrown off by centrifugal force, thereby further improving the cleanliness of the plate-like metal parts and reducing the occurrence of increased costs caused by manual processing in the later stage.

[0044] The cleaning unit 400 includes a pressure plate 401, which is placed at the bottom of the feed rod 1021. A vertical plate 4011 is welded to the bottom of the pressure plate 401. The vertical plate 4011 is provided with a guide slot 4012. The guide slot 4012 is inclined, and a scraper 4021 is slidably mounted on the guide slot 4012. The bottom of the scraper 4021 is in contact with the filter 1032. As the turntable rotates, the feed rod squeezes the pressure plate downward, driving the vertical plate to slide downward synchronously. The guide slots on the surface of the vertical plate slide downward, squeezing the scraper. The scraper is squeezed by the inclined guide slot, and ultimately drives the scraper to move along the surface of the filter, cleaning the debris filtered on the surface and reducing the possibility of clogging.

[0045] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in a specific embodiment, a feed guide groove 1013 is installed on one side of the conveying frame 101, and the feed guide groove 1013 and the outlet of the cold heading machine body 500 correspond to each other, and a conveying guide groove 1014 is installed on the other side of the conveying frame 101, and the conveying guide groove 1014 and the feed guide groove 1013 are in an inclined state, and the outlet position of the conveying guide groove 1014 corresponds to above the centrifugal barrel 303. The products produced by the cold heading machine body 500 can enter the interior of the conveying frame 101 through the feed guide groove 1013, and the conveying guide groove 1014 can further convey the products to the interior of the centrifugal barrel 303.

[0046] like Figure 3 and Figure 4 As shown, further, a protective cover 2033 is movably provided on the transmission shaft 203, and the protective cover 2033 covers each pair of worms 2031 and worm wheels 2032, and the protective cover 2033 is fixedly connected to the side wall of the conveyor frame 101. When the driving motor 201 is started, the driving motor 201 drives the rotating shaft 2011 to rotate synchronously, and the rotating shaft 2011 is provided with a driving pulley 202. At this time, the driving pulley 202 rotates synchronously, and the driving pulley 202 drives the driven pulley 2022 to rotate through the belt 2021, which in turn can drive the connected transmission shaft 203 to rotate, and the transmission shaft 203 can drive the worm 2031 to start rotating, and the worm 2031 can drive the worm wheel 2032 to move synchronously, and then drive the coaxially connected turntable 102 to start moving. Example

[0047] The difference between the above embodiment and this embodiment is that: Figure 3 and Figure 5As shown, the outer frame of the filter 1032 is installed with a card plate 103, and the card plate 103 is placed on the outside of the collection box 1012. A handle 1031 is installed on the card plate 103, and a plurality of pairs of anti-slip grooves are provided on the handle 1031. The position of the filter 1032 can be limited by the card plate 103, and then the card plate 103 and the filter 1032 can be removed from the inside of the collection box through the handle 1031, so as to facilitate the disassembly operation at a later time.

[0048] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in a specific embodiment, a support frame 301 is provided at the bottom of the splash-proof bucket 302, and a support groove 3011 is opened on the support frame 301. The support groove 3011 and the bottom of the splash-proof bucket 302 are movably connected. A support leg 3012 is installed at the bottom of the support frame 301, and a return pipe 3022 is installed at the bottom of the splash-proof bucket 302. The return pipe 3022 is in an inclined state, and the outlet of the return pipe 3022 and the collection box 1012 are connected to each other. The support frame 301 supports the splash-proof bucket 302, and the thrown oil is moved back to the inside of the collection box 1012 through the return pipe 3022, so as to facilitate re-collection later.

[0049] like Figure 7 As shown, further, a rectangular plug 3032 is installed at the bottom of the centrifugal bucket 303, and a mounting seat 3021 is movably provided at the bottom of the splash-proof bucket 302. A rectangular groove is provided at the bottom of the mounting seat 3021, and the rectangular plug 3032 is movably inserted into the rectangular groove. The rectangular plug 3032 and the rectangular groove are inserted into each other to limit the rotation of the centrifugal bucket 303. Example

[0050] The difference between the above embodiment and this embodiment is that: Figure 7 and Figure 9 As shown, a threaded sleeve 304 is installed on the top of the splash-proof bucket 302, and a synchronous bracket 3041 is movably provided on the threaded sleeve 304, and an arched bracket 3042 is installed at the bottom of the synchronous bracket 3041. A pressure wheel 3043 is movably provided on the arched bracket 3042, and the bottom of the pressure wheel 3043 contacts the upper surface of the centrifugal bucket 303. A locking bolt 3044 is movably provided on the synchronous bracket 3041, and the end of the locking bolt 3044 is screwed into the threaded sleeve 304. During the rotation of the centrifugal bucket, the centrifugal bucket 303 can be pressed by the pressure wheel 3043 to ensure that the driven bevel gear and the driving bevel gear on the centrifugal bucket 303 are engaged, so that the centrifugal bucket can rotate. Later, the synchronous bracket 3041 and the threaded sleeve 304 can be disassembled by the locking bolt 3044, which facilitates the later replacement of the centrifugal bucket 303.

[0051] like Figure 5 and Figure 6 As shown, in a specific embodiment, a synchronous plate 402 is installed on the scraper 4021, and guide sliders 4022 are installed on both sides of the synchronous plate 402. The guide sliders 4022 are slidably set on the guide slots 4012, and the horizontal length of the guide slots 4012 corresponds to the length of the conveyor frame 101. A rubber sleeve is provided at the bottom of the scraper 4021, and a limit rod 4023 is provided inside the synchronous plate 402, which is movable and inserted. The two ends of the limit rod 4023 are respectively installed on the inner wall of the collection box 1012. When the turntable 102 rotates clockwise, the feed rod 1021 on the right side rotates downward, pressing the bottom pressure plate 401 to move downward, and the pressure plate 401 pushes the bottom vertical plate 4011 to slide downward, pushing the top rod 4031 to slide inside the sleeve 403, squeezing the internal reset spring, and facilitating the reset later through the reset spring.

[0052] like Figure 5 and Figure 6 As shown, further, a top rod 4031 is installed on the inner walls of both sides of the vertical plate 4011, and a sleeve 403 is movably inserted on the top rod 4031. The sleeve 403 is fixed on the collection box 1012, and a return spring is clamped at the bottom of the inner cavity of the sleeve 403, and the other side of the return spring and the bottom of the top rod 4031 are clamped with each other. When the vertical plate 4011 moves downward, the guide slot 4012 on the vertical plate 4011 moves downward synchronously, and a scraper 4021 is slidably provided on the guide slot 4012. At this time, the height of the scraper 4021 remains unchanged, so the guide slider 4022 on the scraper 4021 moves to the right along the guide slot 4012, and the scraper 4021 drives the synchronous plate 402 to move along the filter 1032, which can clean the impurities filtered on the filter 1032, and the scraper 4021 always moves along the limit rod 4023, which can ensure that the scraper 4021 and the filter 1032 are closely fitted, thereby improving the cleaning efficiency.

[0053] The implementation principle of the discharge mechanism of a cold heading machine for small metal parts in this embodiment is as follows:

[0054] The plate-shaped metal parts 600 produced by the cold heading machine body 500 fall onto the conveying unit 100 and then onto the conveying rack 101 .

[0055] Then the operator needs to start the drive motor 201, and the drive motor 201 drives the rotating shaft 2011 to rotate synchronously, and a drive pulley 202 is provided on the rotating shaft 2011. At this time, the drive pulley 202 rotates synchronously, and the drive pulley 202 drives the driven pulley 2022 to rotate through the belt 2021, and then drives the connected transmission shaft 203 to rotate, and the transmission shaft 203 can drive the worm 2031 to start rotating, and the worm 2031 can drive the worm wheel 2032 to move synchronously, and then drive the coaxially connected turntable 102 to start moving.

[0056] When the turntable 102 rotates clockwise, Figure 5 As shown, after the two turntables 102 on the left rotate, the left feed rod 1021 on the left turntable 102 starts to rotate upward synchronously, thereby lifting the plate metal part 600 upward as a whole and separating it from the positioning rod 1011, and the left feed rod 1021 moves to the right as a whole, thereby driving the plate metal part 600 to start moving to the right, until the left feed rod 1021 moves to the right, at this time the plate metal part 600 has moved to the right to the distance of one turntable 102, and continues to move through the second and third turntables. Rotation will drive the plate metal part 600 to move continuously. Repeat the above operations in sequence, and eventually the plate metal part 600 can be moved to the far right, and finally slide into the centrifugal barrel 303 through the inclined conveying guide groove 1014. Through the above operations, the plate metal part 600 can be driven to move step by step, avoiding the situation where the inclined guide plate causes it to slide too fast. In addition, through the above operations, the plate metal part 600 can be retained on the conveying rack 101 for a long time, so that the oil on the surface can slide off more thoroughly.

[0057] During the startup of the driving motor 201, the rotating shaft 2011 on the surface can drive the driving bevel gear 2012 to rotate, and the side wall of the driving bevel gear 2012 is meshed with a driven bevel gear 3033, which drives the centrifugal bucket 303 on the side wall to start rotating. As the centrifugal bucket 303 rotates at high speed, the internal plate-shaped metal parts 600 can be driven to rotate synchronously, and the oil stains remaining on the surface are thrown out by centrifugal force, and the thrown oil is moved back to the inside of the collection box 1012 through the reflux pipe 3022, which is convenient for later collection.

[0058] When the turntable 102 rotates clockwise, the feed rod 1021 on the right side rotates downward, pressing the bottom pressure plate 401 to move downward, and the pressure plate 401 pushes the bottom vertical plate 4011 to slide downward, pushing the top rod 4031 to slide inside the sleeve 403, squeezing the internal reset spring, and facilitating the reset later through the reset spring. When the vertical plate 4011 moves downward, the guide slot 4012 on the vertical plate 4011 moves downward synchronously, and the guide slot 4012 moves downward synchronously. 12 is provided with a scraper 4021 slidingly. At this time, the height of the scraper 4021 remains unchanged, so the guide slider 4022 on the scraper 4021 moves to the right along the guide slot 4012, and the scraper 4021 drives the synchronous plate 402 to move along the filter 1032, so as to clean the impurities filtered on the filter 1032, and the scraper 4021 always moves along the limit rod 4023, which can ensure that the scraper 4021 and the filter 1032 are closely fitted, thereby improving the cleaning efficiency.
