[0052] The present invention will now be further described in conjunction with specific embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0053] like Figures 1 to 4 As shown, a soft metal ring feeding device comprises

[0054] A track 2, wherein a material pushing trough 21 is provided on the track 2, a material preparation station and a material unloading station are provided in the material pushing trough 21, and a material unloading hole 23 is provided in the material unloading station;

[0055] The push plate 24 reciprocates in the push groove and is suitable for pushing the metal ring of the material preparation station toward the material unloading station;

[0056] At least two magnets 6 are fixedly arranged on the front side of the inner wall of the material pushing groove of the material unloading station, and each magnet 6 is suitable for actively sucking the metal ring that has not been completely sent into the material unloading station into the material unloading station, and restricting the metal ring in the material unloading station to prevent the metal ring from falling from the material unloading hole 23 due to gravity;

[0057] The blanking press head 53 is driven by the blanking driving mechanism to move up and down at the blanking station, and is suitable for pressing the metal ring at the blanking station out of the blanking hole 23 into the mold cavity 11 of the lower turntable 1.

[0058] In this embodiment, the track 2 is a non-magnetic steel track 2, which is used to prevent the track 2 from being magnetized by the magnet 6, thereby affecting the stable adsorption of the metal ring at the unloading station and preventing the metal ring from flipping at the unloading station.

[0059] In this embodiment, the diameter of the discharge hole 23 is 5-10s larger than the diameter of the discharge pressure head 53.

[0060] In this embodiment, the push plate 24 is driven by a push cylinder, and the push cylinder is arranged on the track 2 .

[0061] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, a feeding trough 22 is also provided on the track 2, and the front end of the feeding trough 22 is connected to the material preparation station, so that the metal rings in the feeding trough 22 can be successively output to the material preparation station;

[0062] The feeding air nozzle 31 is located at the feeding side of the feeding trough 22 and is suitable for blowing air toward the discharging direction of the feeding trough 22 to move each metal ring in the feeding trough 22 toward the front end and send the frontmost metal ring to the material preparation station of the pushing trough 21.

[0063] In this embodiment, the feeding trough 22 is used to store metal rings to be fed. The feeding air nozzle 31 ejects air and blows the multiple metal rings in the feeding trough 22 to slide forward in the feeding trough 22, thereby blowing each metal ring to the material preparation station one by one.

[0064] In this embodiment, the blowing angle of the feeding air nozzle 31 is inclined downward toward the feeding trough 22, and the specific inclination angle is adjusted by the technical personnel according to the actual situation.

[0065] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, it also includes

[0066] The material distribution air nozzle 32 is located at the discharge side of the upper material chute 22;

[0067] When the frontmost metal ring in the feeding chute 22 is delivered to the material preparation station, the material separation air nozzle 32 is suitable for blowing air toward the frontmost metal ring in the feeding chute 22, driving each metal ring in the feeding chute 22 to move toward the rear end, so that the frontmost metal ring in the feeding chute 22 is separated from the metal rings in the material preparation station.

[0068] In this embodiment, the air outlet angle of the material distribution air nozzle 32 is also inclined downward and toward the upper material trough 22, so as to blow the metal ring in the upper material trough 22 backward.

[0069] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, it also includes

[0070] The limiting air nozzle 33 is suitable for blowing air toward the metal ring at the material preparation station so that the metal ring abuts against the push plate 24 or the inner wall of the track 2 to limit the metal ring at the material preparation station.

[0071] In the embodiment, the limiting air nozzle 33 is disposed in the track 2 , and an air nozzle mounting hole is opened in the track 2 . The limiting air nozzle 33 blows air toward the metal ring of the material preparation station, thereby limiting the metal ring at the front end of the push plate 24 .

[0072] In this embodiment, the blowing angle of the limiting air nozzle 33 is inclined upward. The advantage of this blowing angle is that it can enable the metal ring to obtain an upward lifting force, thereby reducing the friction between the metal ring and the bottom surface of the pushing trough 21, thereby reducing the probability of deformation of the metal ring during the pushing and starting process.

[0073] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, it also includes

[0074] The first sensor 41 is arranged at one side of the material preparation station and is suitable for detecting whether there is a metal ring on the material preparation station;

[0075] The second sensor 42 is disposed at one side of the feeding chute 22 and is suitable for detecting whether there is a metal ring in the feeding chute 22 .

[0076] In this embodiment, the first sensor 41 and the second sensor 42 are both fixedly arranged on the track 2. Both sensors are connected to the controller, and the sensed information is fed back to the controller, which outputs instructions according to the information collected by the two sensors.

[0077] Working principle: When the first sensor 41 detects that there is no metal ring at the material preparation station, the feeding air nozzle 31 can be controlled to start blowing and convey the metal ring to the material preparation station. When the first sensor 41 detects that there is a metal ring, the push plate 24 can start pushing the metal ring.

[0078] When the second sensor 42 detects that there is a metal ring in the upper feeding trough 22 , the vibration plate can be in a standby state. When the second sensor 42 cannot detect the metal ring, the vibration plate starts to transport the metal ring into the upper feeding trough 22 .

[0079] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, the blanking station is provided with two magnets 6 , which are respectively arranged on both sides of the blanking station, and the metal ring entering the blanking station is adsorbed by the two magnets 6 .

[0080] In this embodiment, two magnets 6 are arranged in the track 2 body above the front semicircle area of ​​the unloading hole 23, and the two magnets 6 are distributed left and right in the front semicircle area. The metal ring entering the unloading station can be attracted in a relatively balanced manner through the two magnets 6; assuming that both magnets 6 are arranged above the front end area of ​​the unloading hole 23, in this case, if the part is heavy, the magnet 6 is too close to the front end, and the part will fall into the track 2 ring, or the part will flip. To avoid this situation, the two magnets 6 need to be appropriately dispersed to the left and right sides to balance the attraction force on the metal ring.

[0081] In this embodiment, the installation structure of the magnet 6 at the blanking station is:

[0082] The rail 2 is provided with a mounting hole, and the magnet 6 is fixedly disposed in the mounting hole.

[0083] The installation position of the magnet 6 in the installation hole can be rotated according to actual conditions, and can be left at a certain distance from the hole opening, or can be flush with the hole opening, but the magnet 6 cannot extend beyond the hole opening to the unloading station of the material pushing trough 21.

[0084] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, the material feeding drive mechanism includes

[0085] The support 5 is fixedly arranged; the support 5 is fixedly connected to the track 2;

[0086] The lifting cylinder 51 is fixedly arranged on the bracket and is suitable for driving the lifting seat 52 to move up and down;

[0087] The lifting seat 52 has one end connected to the push rod of the lifting cylinder 51 and the other end mounted with a blanking press head 53 .

[0088] In this embodiment, a guide rail pair is provided between the lifting seat 52 and the support 5 so that the lifting seat 52 can move up and down stably.

[0089] In this embodiment, the installation structure between the blanking press head 53 and the lifting seat 52 is:

[0090] The upper end of the blanking press head 53 passes through the lifting seat 52 to form a sliding fit between the blanking press head 53 and the lifting seat 52. A baffle is fixedly arranged on the upper end of the blanking press head 53. The baffle is used to limit the blanking press head 53 from sliding downward out of the lifting seat 52. A spring is sleeved on the blanking press head 53, and the lower end of the spring abuts against the blanking press head 53. The upper end of the spring abuts against the lower end surface of the lifting seat 52 to form a spring movement between the blanking press head 53 and the lifting seat 52.

[0091] In this embodiment, the diameter of the blanking ram 53 is smaller than the blanking hole 23 , so that the blanking ram 53 can pass through the blanking hole 23 smoothly.

[0092] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, it also includes

[0093] A side support 54, one end of which is fixedly connected to the lifting seat 52, and the other end of which is installed with a reset pressure head 55;

[0094] The reset pressing head 55 moves up and down along with the lifting seat 52 and is suitable for pressing the metal ring into the mold cavity 11 of the rotating disk 1 .

[0095] In this embodiment, the installation structure between the reset pressure head 55 and the side support 54 is the same, and the reset pressure head 55 also performs an upward and downward elastic movement.

[0096] Specifically, as an optional implementation in this embodiment, Figures 1 to 4As shown, it also includes

[0097] The cover plate 25 is arranged at the upper end of the track 2 to cover the material pushing trough 21 and the material loading trough 22 .

[0098] In this embodiment, the cover plate 25 is fixed on the track 2 by screws. The cover plate 25 restricts the metal ring from moving upward in the feeding trough 22 and the pushing trough 21, so that the metal ring can only move horizontally in the trough.

[0099] There is a gap between the cover plate 25 and the upper material trough 22 , and the gap is used to ensure that the feeding air nozzle 31 and the dividing air nozzle 32 can blow air into the upper material trough 22 .

[0100] The working principle of the soft metal ring feeding device in this embodiment is as follows:

[0101] A vibration plate is connected to the feeding side of the upper feeding trough 22, and a plurality of metal rings are arranged on the vibration plate. The metal rings are input into the upper feeding trough 22 through the vibration plate; a turntable 1 is arranged below the unloading station of the track 2, and a plurality of mold cavities 11 are provided on the turntable 1. The purpose of the metal ring unloading device of the present invention is to accurately install the metal rings in the vibration plate into each mold cavity 11 of the turntable 1 one by one. The turntable 1 rotates according to the set requirements so that the mold cavities 11 can be moved one by one below the unloading station of the track 2.

[0102] The metal rings enter the feeding trough 22 and are arranged one by one in the trough. The feeding air nozzle 31 blows air into the feeding trough 22 to blow the metal rings forward, so that the metal rings at the front end of the feeding trough 22 are moved to the material preparation station of the pushing trough 21. The limiting air nozzle 33 blows air to the metal rings at the material preparation station to limit the metal rings at the material preparation station.

[0103] The push plate 24 moves forward to move the metal ring toward the unloading station. When the metal ring has not completely entered the unloading station, the metal ring is directly adsorbed into the unloading station through the adsorption of the two magnets 6. This avoids the situation where the push plate 24 directly pushes the metal ring to the unloading station and squeezes and deforms the metal ring in the unloading station due to the inaccurate extension stroke of the push plate 24. Now, since two magnets 6 are provided, the magnet 6 can actively adsorb the metal ring that has not entered the unloading station to prevent deformation. It can also stably adsorb the metal ring through the structure of the two magnets 6 distributed left and right in the front semicircle of the unloading station to prevent the metal ring from falling directly from the unloading hole 23.

[0104] Embodiment 2

[0105] A method for blanking a soft metal ring is provided, using the soft metal ring blanking device of embodiment 1, comprising the following steps:

[0106] Step S01, transporting the metal ring to a material preparation station;

[0107] Step S02, the push plate 24 pushes the metal ring to move toward the unloading station in front. When the metal ring has not completely entered the unloading station, the metal ring is sucked into the unloading station by the two metal rings in the unloading station. At this time, the metal ring is located above the unloading hole 23;

[0108] Step S03, the blanking press head 53 moves downward, driving the metal ring to move out of the blanking hole 23 and enter the mold cavity 11 of the lower turntable 1 to complete the blanking.

[0109] The method for cutting the soft metal ring in this embodiment can prevent the metal ring from being deformed when the push plate 24 pushes the metal ring, thereby improving the yield rate of the metal ring during the cutting process.

[0110] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
