[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 materials, the plate-shaped metal parts are naturally slid down through the inclined guide plate.

The following embodiments are used to illustrate the present invention. Example

[0019] like Figures 1 to 9 As 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. The transport unit 100 includes a transport frame 101, one side of which is equipped with a plurality of pairs of positioning rods 1011, and the other side of the transport frame 101 is movably equipped with a plurality of pairs of turntables 102, each pair of turntables 102 is horizontally equipped with two feed rods 1021, and the two feed rods 1021 are respectively placed on both sides of the corresponding positioning rods 1011, and the feed rods 1021 and the positioning rods 1011 are both equipped with plate-shaped metal parts 600, and the bottom of the transport frame 101 is connected to a collection box 1012, and the collection box 1012 is equipped with a filter screen 1032; The driving unit 200 includes a driving motor 201 and a transmission shaft 203. The output shaft of the driving motor 201 is installed with a rotating shaft 2011. The end of the rotating shaft 2011 is installed with a driving bevel gear 2012. The rotating shaft 2011 is also installed with a driving pulley 202. A plurality of worms 2031 are arranged 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-shaped metal parts and move them to the right until they move to the next workstation, and continue to drive the lifted plate-shaped 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-shaped metal parts from sliding off 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.

[0020] 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 meshed 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 meshing of the two bevel gears, and the oil attached to the plate-like metal parts is thrown off through the centrifugal force, thereby further improving the cleanliness of the plate-like metal parts and reducing the cost increase caused by manual processing in the later stage.

[0021] The cleaning unit 400 includes a pressing plate 401, which is placed at the bottom of the feed rod 1021. A vertical plate 4011 is welded to the bottom of the pressing plate 401.

The bottom of the scraper 4021 fits the filter screen 1032. During the rotation of the turntable, the feed rod squeezes the pressing plate to move downward, driving the vertical plate to slide downward synchronously. The guide slot on the surface of the vertical plate slides downward to squeeze the scraper. The scraper is squeezed by the inclined guide slot, and finally the scraper can be driven to move along the surface of the filter screen, so that the debris filtered on the surface can be cleaned, reducing the occurrence of blockage.

[0023] 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 wraps 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. The driving motor 201 is started, and the rotating shaft 2011 is driven to rotate synchronously by the driving motor 201, 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, and then 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

[0024] The difference between the above embodiment and this embodiment is that: Figure 3 and Figure 5 As 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 moved out of the collection box through the handle 1031, so as to facilitate the disassembly operation at a later time.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, in a specific embodiment, a support frame 301 is provided at the bottom of the splash-proof bucket 302, 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 plugged, a support leg 3012 is installed at the bottom of the support frame 301, a return pipe 3022 is installed at the bottom of the splash-proof bucket 302, the return pipe 3022 is in an inclined state, 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 at a later time.

[0026] like Figure 7 As shown, further, a rectangular plug rod 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 opened at the bottom of the mounting seat 3021, and the rectangular plug rod 3032 is movably inserted inside the rectangular groove. The rectangular plug rod 3032 and the rectangular groove are inserted into each other to limit the rotation of the centrifugal bucket 303. Example

[0027] The difference between the above embodiment and this embodiment is that: Figure 7 and Fig. 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 meshed, 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, so as to facilitate the replacement of the centrifugal bucket 303 later.

[0028] like Figure 5 and Figure 6As 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 slide 4012, and the horizontal length of the guide slide 4012 corresponds to the length of the conveying frame 101. A rubber sleeve is set at the bottom of the scraper 4021, and a limit rod 4023 is inserted and inserted inside the synchronous plate 402. 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.

[0029] 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, so that the impurities filtered on the filter 1032 can be cleaned, 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.

[0030] The implementation principle of the discharge mechanism of a cold heading machine for small metal parts in this embodiment is as follows: 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 frame 101 .

[0031] Then the operator needs to start the drive motor 201, and the drive motor 201 drives the rotating shaft 2011 to rotate synchronously. The rotating shaft 2011 is provided with a drive pulley 202. 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 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.

[0032] When the rotating disk 102 rotates clockwise, Figure 5 As shown, after the two left turntables 102 rotate, the left feed rod 1021 on the left turntable 102 starts to rotate upward synchronously, so that the plate-shaped metal part 600 can be lifted upward as a whole and separated from the positioning rod 1011, and the left feed rod 1021 moves to the right as a whole, thereby driving the plate-shaped metal part 600 to start moving to the right, until the left feed rod 1021 moves to the right, at which time the plate-shaped 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-shaped metal part 600 to move continuously. By repeating the above operations in sequence, the plate-shaped 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-shaped 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-shaped 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.

[0033] 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, and the centrifugal bucket 303 on the side wall starts to rotate through the driven bevel gear 3033. As the centrifugal bucket 303 rotates at a 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, so as to be convenient for re-collection later.

[0034] 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 later reset through the reset spring, and when the vertical plate 4011 moves downward, the guide slot 4012 on the vertical plate 4011 moves downward synchronously, and the guide slot 4012 on the vertical plate 4011 moves downward synchronously, and the guide slot 4012 on the vertical plate 4011 moves downward. 12 is slidably provided with a scraper 4021. 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 screen 1032, so as to clean the impurities filtered on the filter screen 1032, and the scraper 4021 always moves along the limit rod 4023, so as to ensure that the scraper 4021 and the filter screen 1032 are closely fitted, thereby improving the cleaning efficiency.
