DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-9 A cemented carbide powder forging processing equipment provided by an embodiment of the present invention includes a forging table 1 equipped with a punch head 101, a die base 2 is installed on the table top, and also includes a mobile feeding mechanism 3, which is movably installed on the forging table 1 and moves back after feeding the material into the die base 2, and an ejection mechanism 4, one end of which is located inside the die base 2 and the other end is transmission-connected to the mobile feeding mechanism 3. When the mobile feeding mechanism 3 moves back, the feeding is stopped, and the ejection mechanism 4 is driven to lift the blank formed in the die base 2, and then push the blank out when moving outward.

[0034] Specifically, the die base 2 has a die cavity 201 for alloy powder to enter. The mobile feeding mechanism 3 will feed the alloy powder into the die cavity 201 on the die base 2 during the movement. When the die cavity 201 is full, the mobile feeding mechanism 3 moves away to allow the punch head 101 to press the alloy material in the die cavity 201. After the pressing is completed, the punch head 101 rises and resets. When the mobile feeding mechanism 3 moves back further, it will drive the ejection mechanism 4 to move upward, thereby using the ejection mechanism 4 to lift the blank that has been pressed and formed in the die base 2, so that the position of the blank is higher than the die base 2, so that when the mobile feeding mechanism 3 moves back again, it can push the blank away from the bottom of the punch head 101.

[0035] Compared with the prior art, the embodiment of the present invention facilitates the transportation of alloy powder from other areas outside the stamping operation area into the die cavity 201 in the die base 2 by setting a mobile feeding mechanism 3. At the same time, the mobile feeding mechanism 3 stops feeding when it moves back, and drives the ejection mechanism 4 to lift the blank formed in the die base 2, and then uses the re-moved mobile feeding mechanism 3 to push out the blank, allowing the blank to leave the bottom of the punch head 101, thereby avoiding the staff from taking the blank in the operating area of ​​the punch head 101, reducing the safety hazards during operation, and allowing a series of inspection operations on the alloy blank to be performed with greater confidence.

[0036] In a further embodiment of the present invention, a feeding bin 105 is fixedly installed on the inner wall of the forging table 1, and a feeding hose 106 is installed on the top of the feeding bin 105. The mobile feeding mechanism 3 includes a feeding sleeve 302 movably inserted on the feeding bin 105, and a discharge port 303 and a scraping assembly 5 are provided on one side of the bottom of the feeding sleeve 302 above the die base 2. The feeding sleeve 302 is used to transport the material in the feeding bin 105 into the die base 2, and a feeding hose 106 is installed between the other side of the bottom of the feeding sleeve 302 and the inner wall of the feeding bin 105. A reset spring 304 is installed. Specifically, the feeding end of the feeding sleeve 302 is always inside the feeding bin. After entering the feeding bin 105, the material will fall into the feeding sleeve 302 under the guidance of the internal structure of the feeding bin 105, and then be discharged into the mold cavity 201 in the mold base 2 through the discharge port 303 under the feeding sleeve 302. The reset spring 304 provides power for the feeding sleeve 302 to move out when the punch head 101 moves up, ensuring that the feeding sleeve 302 is reset in time to speed up the efficiency of continuous operation.

[0037] In a further embodiment of the present invention, the top of the feeding sleeve 302 is symmetrically fixedly connected with an abutment frame 305, and one side of the punching head 101 is fixedly connected with a pressure rod 102, and the bottom of the pressure rod 102 abuts against the two abutment frames 305 at the same time. When the punching head 101 moves downward, the abutment frame 305 is squeezed by the pressure rod 102 to force the feeding sleeve 302 to move toward the feeding bin 105. Specifically, the abutment frame 305 is provided with an inclined section and a vertical section, and the inclined section is located above the vertical section. In the initial stage of the descent of the punching head 101, the pressure rod 102 first abuts against the inclined section of the abutment frame 305, and is pushed by the vertically descending pressure rod 102. The abutment frame 305 then drives the feeding sleeve 302 to move horizontally toward the feeding bin 105, so that the scraping assembly 5 can clean up the excess alloy powder in the die base 2 again, and the feeding sleeve 302 can be moved away from the top of the die base 2 to prepare for the subsequent stamping of the punch head 101. During the punching stroke of the punch head 101, the side of the pressure rod 102 always abuts against the vertical section of the abutment frame 305 to prevent the feeding sleeve 302 from moving out under the action of the reset spring 304 during the punching stroke. At the same time, after the side of the pressure rod 102 abuts against the vertical section of the abutment frame 305, it can also prevent the punch head 101 from deflecting.

[0038] In a further embodiment of the present invention, a feed auger 306 is rotatably connected in the feed sleeve 302, and a driving member 6 that is transmission-connected to the feed auger 306 is installed on the forging table 1. When the feed sleeve 302 moves toward the feed bin 105 to allow the discharge port 303 to leave the die base 2, the driving member 6 and the feed auger 306 are disconnected, that is, after the feed sleeve 302 moves away from the die base 2, the feed auger 306 is stopped by disconnecting the driving member 6 and the feed auger 306 to prevent the alloy powder from being discharged outside the die cavity 201 of the die base 2. Specifically, the driving member 6 includes a driving motor 601 fixed to the outer wall of the forging table 1, and the output shaft of the driving motor 601 is installed with a transmission shaft 602 in the feed bin 105. The central part of the feed auger 306 is provided with a There is a hollow shaft 308 that cooperates with the transmission shaft 602. The transmission end of the transmission shaft 602 is inserted into the hollow shaft 308 of the transmission shaft 602, and a connecting block 603 is provided on the transmission end. A transmission sleeve 309 is sleeved inside the hollow shaft 308. The transmission sleeve 309 is provided with a horizontal groove 310 and an annular groove 311 that match the connecting block 603. After the conveying auger moves away from the die base 2, the connecting block 603 on the transmission shaft 602 is in the annular groove 311. Even if the driving motor 601 is always in operation, the feeding auger in the feeding sleeve 302 can be stopped after the feeding sleeve 302 moves back to the specified position, so that during the continuous feeding and stamping process, there is no need to repeatedly start and stop the driving component 6, thereby extending the service life of the driving motor 601.

[0039] In a further embodiment of the present invention, the ejection mechanism 4 includes a lifting plate 401 located in the forging table 1, the lifting plate 401 is located below the die base 2, a plug rod 402 is fixedly connected to one side of the top of the lifting plate 401, a plug hole matching the plug rod 402 is vertically opened in the die base 2, the top of the plug rod 402 passes through the die base 2 and is fixedly connected to a gasket 403, the gasket 403 is padded in the die cavity 201 of the die base 2, and a compression spring 406 is also sleeved outside the plug rod 402, and the compression spring 406 is located between the die base 2 and Between the lifting plates 401, one end of the compression spring 406 abuts against the bottom of the die base 2, and the other end abuts against the top of the lifting plate 401. The other side of the top of the lifting plate 401 is elastically connected with a movable frame 404. A transmission mechanism 7 is installed between the feeding sleeve 302 and the movable frame 404. The movable frame 404 is located between the transmission mechanism 7 and the abutment frame 305. When the feeding sleeve 302 moves backward, the abutment frame 305 pushes the movable frame 404 to move the movable frame 404 toward the transmission mechanism 7. Then, the feeding sleeve 302 is used to move the movable frame 404 toward the transmission mechanism 7. The cylinder 302 continues to move backward to allow the transmission mechanism 7 to drive the movable frame 404 to move upward. Specifically, the movable frame 404 is slidably installed on the lifting plate 401, and the bottom of the movable frame 404 is symmetrically fixedly connected with a slider 407. The top surface of the lifting plate 401 is horizontally provided with a slide groove 408 that matches the slider 407, and the inner wall of the slide groove 408 is fixedly connected to a tension spring 409 connected to the movable frame 404 on the side close to the insertion rod 402. The tension spring 409 is installed so that the feeding sleeve 302 can be moved out of the lower During the material feeding process, the connection between the movable frame 404 and the transmission assembly which are not squeezed is disconnected in time to prevent the gasket 403 from moving up and down and affecting the normal filling of the material in the mold cavity 201 of the mold base 2 during material feeding. The compression spring 406 will push the lifting plate 401 downward after the movable frame 404 and the transmission assembly are disconnected from the transmission, so that the entire ejection mechanism 4 is reset to the previous position, and the gasket 403 moves down and fits with the bottom of the inner wall of the mold cavity 201 of the mold base 2 to achieve continuous filling and pressing operations.

[0040] In a further embodiment of the present invention, the transmission mechanism 7 includes a gear column 701 rotatably mounted on one side of the feeding bin 105, a gear plate 307 meshing with the gear column 701 is horizontally fixedly connected to the bottom of the feeding sleeve 302, and a rack 405 meshing with the gear column 701 is vertically fixedly connected to one side of the movable frame 404. Specifically, a bracket 703 is fixedly connected to the bottom of one side of the feeding bin 105 close to the punching head 101, the gear column 701 is rotatably mounted in the middle of the bracket 703, and the gear column 701 is below the feeding sleeve 302. When the feeding sleeve 302 moves toward the feeding bin 105, the gear plate 307 on the feeding sleeve 302 will drive the gear column 701 to rotate counterclockwise, and when the feeding sleeve 302 moves toward the die base 2, the gear plate 307 will drive the gear column 701 to rotate clockwise, that is, the feeding sleeve 302 moves in two opposite directions. During the process, the tooth column 701 will rotate forward and reverse, and the rotation of the tooth column 701 will drive the rack 405 to move vertically up and down, and the abutment frame 305 will push the movable frame 404 to move it toward the transmission mechanism 7 until the rack 405 on the movable frame 404 engages with the upper tooth column 701. At this time, the counterclockwise rotating tooth column 701 will drive the rack 405 to move upward, thereby forcing the entire jacking mechanism to rise, and use the gasket 403 in the jacking mechanism to eject the alloy part pressed in the die cavity 201 of the die base 2. When the feeding sleeve 302 moves toward the direction of the die base 2, the abutment frame 305 will gradually loosen the movable frame 404. At this time, the movable frame 404 moves back under the action of the tension spring 409, so that the rack 405 on the movable frame 404 is no longer engaged with the tooth column 701, so that the compression spring 406 can easily reset the lifting plate 401, allowing the lifting plate 401 and the entire lifting mechanism to descend.

[0041] In a further embodiment of the present invention, a protrusion 312 is elastically rotatably connected to the abutment frame 305. At the same time, a limiting column 313 for limiting the counterclockwise rotation of the protrusion 312 is fixedly connected to the side wall of the abutment frame 305. The limiting column 313 is located above the protrusion 312 and abuts against the edge of the protrusion 312. When the pressure rod 102 moves downward along the abutment frame 305, it will abut against the protrusion 312, forcing the protrusion 312 to rotate. At this time, the protrusion 312 will not affect the downward movement of the pressure rod 102. When the pressure rod 102 moves upward along the abutment frame 305, if it abuts against the protrusion 312, this When the pressing rod 102 moves up along the raised portion of the protrusion 312, the feeding sleeve 302 will be forced to move further toward the feeding bin 105, so that the ejection mechanism 4 can complete the ejection operation of the blank after the punching head 101 moves to a corresponding height. Specifically, the protrusion 312 is elliptical in shape, and a torsion spring 314 is installed between the protrusion 312 and the abutment frame 305. Under the action of the torsion spring 314, the protrusion 312 is horizontal in normal circumstances. The protruding parts on both sides are horizontal. Although the protruding part 312 is forced to rotate when the pressure rod 102 is pressed from above to the protruding part 312, as long as the pressure rod 102 and the protruding part 312 are separated, the protruding part 312 will quickly rotate and reset under the force of the torsion spring 314, which will not affect the normal pressing stroke of the punch head 101, but can change the upward movement stroke of the punch head 101 after the pressing is completed, so that the punch head 101 can drive the feeding sleeve 302 to move further toward the feeding bin 105 during the upward movement, so that the rack 405 on the movable frame 404 meshes with the upper tooth column 701, which When the tooth column 701 rotates counterclockwise, it will drive the rack 405 to move upward, thereby forcing the entire lifting mechanism to rise, and use the gasket 403 in the lifting mechanism to eject the alloy part pressed in the die cavity 201 of the die base 2. When the ejection is completed, the pressure rod 102 also leaves the raised part of the protrusion 312, allowing the feeding sleeve 302 to move outward rapidly under the action of the return spring 304, so that the scraping assembly 5 at the bottom of the feeding sleeve 302 pushes the blank, causing the blank to deviate above the die base 2. At this time, the punch head 101 gradually moves upward with the pressure rod 102, which will cause the scraping assembly 5 to gradually push the blank away from the die base 2.

[0042] In a further embodiment of the present invention, a collecting trough 103 is installed inside the forging table 1, and a sleeve 104 is provided on the table top of the forging table 1 outside the die base 2, and the sleeve 104 is connected with the collecting trough 103. An annular blanking hole is opened on the table top of the forging table 1 at the connection with the die base 2. When the scraping assembly 5 scrapes off the excess alloy powder on the die base 2, the powder will fall into the collecting trough 103 from the gap between the die base 2 and the sleeve 104, so as to facilitate subsequent recycling and use, and a non-return flow blocker 8 is installed between the sleeve 104 and the die base 2, and the non-return flow blocker 8 can prevent the powder from diffusing and discharging. A sealing frame 107 for sealing the discharge port 303 of the feeding sleeve 302 is also installed on the top of 104. Specifically, the non-return flow blocking member 8 includes a retaining ring 801 fixed in the sleeve 104 and a top spring 802 mounted on the outside of the die base 2. The bottom of the top spring 802 rests on the table top of the forging table 1. The top of the top spring 802 is fixedly connected with a non-return ring 803. The top surface of the non-return ring 803 rests on the bottom of the retaining ring 801. The sealing frame 107 can seal the discharge port 303 at the bottom of the feeding sleeve 302 after it is removed, so as to prevent the remaining powder at the discharge port 303 from falling onto the table top of the forging table 1.

[0043] In a further embodiment of the present invention, the outer diameter of the check ring 803 is smaller than the outer diameter of the retaining ring 801, but larger than the inner diameter of the retaining ring 801, and the inner edge of the retaining ring 801 is provided with a chamfered surface, and the check ring 803 has an inclination adapted to the chamfered surface. Specifically, when the scraping component 5 scrapes the excess alloy powder on the mold base 2 into the sleeve 104, if the alloy powder accumulates more, the check ring 803 will be squeezed downward to form a gap between the check ring 803 and the retaining ring 801, allowing the alloy powder to pass through the gap and then enter the aggregate trough 103. When the alloy powder is recovered, the check ring 803 will reset and rise under the action of the top spring 802. After the check ring 803 presses against the retaining ring 801, the gap is closed, thereby preventing the powder entering the aggregate trough 103 from diffusing with the reflux of air, achieving a good recovery effect and avoiding waste of raw materials.

[0044] In a further embodiment of the present invention, a screening net 12 is movably installed in the feeding bin 105, and the screening net 12 is tilted in the feeding bin 105. A support frame 108 for the sliding movement of the screening net 12 is fixedly installed in the feeding bin 105. A connecting rod 702 is installed between the tooth column 701 and the screening net 12. One end of the connecting rod 702 is fixed to the eccentric part of the end face of the tooth column 701, and the other end of the connecting rod 702 is fixed to the side edge of the screening net 12. Specifically, when the feeding sleeve 302 moves back and forth, the tooth plate 307 at the bottom of the feeding sleeve 302 will drive the tooth column 701 to rotate, so that the tooth column 701 drives the screening net 12 through the connecting rod 702. In the process of repeated back and forth movement of the feeding sleeve 302, the alloy powder is also pre-screened, so that the screened raw materials enter the feeding sleeve 302.

[0045] In a further embodiment of the present invention, a return pipe fitting 9 for connecting the aggregate trough 103 and the feed sleeve 302 is installed in the feed bin 105, and a suction assembly 10 connected to the driving member 6 is installed in the return pipe fitting 9, the return pipe fitting 9 includes a feed pipe 901 and a discharge inclined pipe 902 which are connected to each other, the bottom pipe opening of the feed pipe 901 is inserted in the aggregate trough 103, the discharge pipe opening of the discharge inclined pipe 902 is above the feed opening of the feed sleeve 302, the feed pipe 901 is vertically arranged, the discharge inclined pipe 902 is inclinedly arranged, and the discharge inclined pipe 902 is also inclinedly arranged in the feed bin 105 like the screening net 12, and the top of the discharge inclined pipe 902 is connected to the screening net 12, and the powder sifted by the screening net 12 will fall into the discharge inclined pipe 902. Specifically, the suction assembly 10 includes a rotatable installation on the lower The extraction auger 1001 in the material inclined tube 902 has a transmission bevel gear 1002 fixedly connected to the top of the main shaft of the extraction auger 1001, and a driving bevel gear 604 is fixedly sleeved on the transmission shaft 602, and the driving bevel gear 604 is meshed with the transmission bevel gear 1002.
