Description

Technical Field

[0001] This invention relates to the field of metal processing, and more specifically, to an automatic forming and rolling apparatus for a disc-shaped chromium metal target. Background Technology

[0002] When processing metallic chromium powder into metallic chromium targets, it is often calendered by extrusion through rollers on a calender. Calendering is the process of compacting loose metallic chromium powder into a target material with a certain shape and size through mechanical pressure. Most existing production processes metallic chromium powder into disc-shaped metallic chromium targets because disc-shaped metallic chromium targets are easier to handle in subsequent sintering, hot pressing and other processes, and can reduce material loss during processing.

[0003] For example, the "Apparatus for Rolling and Flattening Magnetic Metal Powder" disclosed in Chinese Utility Model Patent (Application No.: 202121986078.7) specifies that it includes a first box and a second box disposed inside the first box. A pressure roller assembly is installed inside the second box. The bottom end of the second box is fixedly connected to the first box through a mounting seat. The two sides of the second box are fixedly connected to the inner wall of the first box through multiple shock-absorbing springs. The above patent can corroborate the defects of the prior art.

[0004] However, the above-mentioned magnetic metal powder rolling and flattening device has some shortcomings in actual use: In the above-mentioned prior art, the metal powder is rolled by two rotating rollers on the roller assembly, but the shape of the rolled metal target is irregular. The irregularly shaped metal target cannot be heated evenly in the subsequent sintering furnace and needs to be further processed into a regular shape, which increases the difficulty and cost of subsequent processing.

[0005] Therefore, we have made improvements to this and proposed an automatic forming and rolling device for disc-shaped chromium metal targets. Summary of the Invention

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] As described in the background section, existing rolling equipment cannot roll metal powder into regular shapes, which increases the difficulty and cost of subsequent processing.

[0040] To address this technical problem, the present invention provides an automatic forming and rolling device for disc-shaped chromium metal targets, which is applied to metal processing.

[0041] For details, please refer to Figures 1-9 The automatic forming and rolling device for disc-shaped chromium metal target material specifically includes: a box body 1, a feeding chamber 101 disposed on the box body 1 and a discharge hole 102 disposed on the box body 1, including an extrusion mechanism 2 disposed on the box body 1 and a discharge mechanism 3 disposed on the box body 1.

[0042] The extrusion mechanism 2 includes a motor 201 mounted on the housing 1, a first roller 202 mounted on the output end of the motor 201, a second roller 203 rotatably mounted inside the housing 1, an extrusion groove 204 mounted on the first roller 202, a top moving column 205 rotatably mounted on the second roller 203, and a synchronous adjustment component 206 mounted inside the housing 1.

[0043] The automatic forming and rolling device for disc-shaped chromium metal targets provided by this invention addresses the problem that existing rolling devices cannot roll metal powder into regular shapes, increasing the difficulty and cost of subsequent processing. This application uses an extrusion mechanism 2 and a discharge mechanism 3 to extrude metal powder into a target material of a regular shape through a pressure block 210, an ejection ring 212, and an extrusion groove 204. The pressure block 210 and the ejection ring 212 are detachable. According to production needs, by replacing the pressure block 210 and the ejection ring 212 with different shapes, targets of different shapes and regular shapes can be rolled out.

[0044] By using the extrusion mechanism 2 and the discharge mechanism 3, the pressure block 210 rotates during the rolling process to polish the metal target material, thereby improving the flatness of the metal target material surface and solving the problem of defects on the surface of the metal target material caused by rolling in the prior art.

[0045] By using the extrusion mechanism 2 and the discharge mechanism 3, the metal powder in the extrusion groove 204 is evenly distributed by the impact of the rack 307 on the extrusion groove 204, thereby reducing the gap between the metal powder and the metal powder in the extrusion groove 204 and solving the problem of uneven metal powder distribution leading to reduced target quality in the prior art.

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] Example 1, please refer to Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, an automatic forming and rolling device for a disc-shaped chromium target material includes multiple extrusion grooves 204 arranged in a circumferential array on a first roller 202, and multiple actuating columns 205 arranged in a circumferential array on a second roller 203. The actuating columns 205 and the extrusion grooves 204 are mutually compatible. In operation, chromium powder is placed into a feed hopper 101, and the powder slides down the feed hopper 101 into the extrusion grooves 204. The motor 201 is started, and its output drives the first roller 202 to rotate, causing the extrusion grooves 204 on the first roller 202 to rotate. 04. The extrusion groove 204 extrudes the top column 205, causing the top column 205 to rotate together with the second roller 203. The bottom of the extrusion groove 204 is disc-shaped. When the extrusion groove 204 and the top column 205 are on the same horizontal line, the top column 205 extrudes the metallic chromium powder into a disc shape, thereby rolling the metallic chromium powder into a disc metallic chromium target. The bottom of the feed bin 101 is in contact with the first roller 202. When the first roller 202 rotates, the metallic chromium powder in the feed bin 101 will gradually enter the extrusion groove 204, thus reducing the leakage of metallic chromium powder during processing.

[0050] Furthermore, the feed hopper 101 is provided with an extension 207, which is adapted to the extrusion groove 204. When the push column 205 and the extrusion groove 204 rotate and are about to contact each other, the extension 207 blocks the metallic chromium powder in the extrusion groove 204, reducing the leakage of metallic chromium powder from the extrusion groove 204 and improving the quality of the metallic chromium powder being rolled into a disc metallic chromium target.

[0051] Furthermore, the synchronous adjustment component 206 includes a rotating shaft 2061 rotatably disposed within the housing 1, a gear ring 2062 mounted on the rotating shaft 2061, a gear 2063 mounted on the actuating column 205, the gear 2063 and the gear ring 2062 being mutually adapted, a gear 2064 mounted on the rotating shaft 2061, a gear ring 2065 disposed within the roller 203, and a drive shaft 2066 rotatably disposed within the housing 1, a gear 2067 mounted on the drive shaft 2066. When the actuating column 205 and the roller 203 rotate synchronously, the gear ring 2065 within the roller 203 drives... Gear 3 2067 rotates, which drives gear 2 2064 to rotate. Gear 2 2064 drives rotating shaft 2061 and gear ring 1 2062 to rotate synchronously. Gear ring 1 2062 drives gear 1 2063 to rotate. Gear 1 2063 drives top column 205 to rotate synchronously. When extrusion groove 204 and top column 205 are on the same horizontal line, the rotating top column 205 rubs against the disc chromium metal target, polishing one end of the rolled disc chromium metal target, thereby improving the surface flatness of the disc chromium metal target and reducing the adhesion of chromium metal powder to top column 205.

[0052] Furthermore, gear 2064 and gear 3067 are mutually compatible, and gear ring 2065 and gear 3067 are mutually compatible, such as... Figure 4 As shown, the gear ratio of gear 2064 is less than that of gear ring 2065. Therefore, the rotation speed of gear 2064 is greater than that of gear ring 2065, which prevents the jacking column 205 from not rotating when the roller 203 rotates.

[0053] Furthermore, a deflection groove 208 is provided at the end of the jacking column 205, and a drive shaft 209 is rotatably mounted within the deflection groove 208. A pressure block 210 is mounted on the drive shaft 209. The connection between the drive shaft 209 and the deflection groove 208 is via a torsion spring. When the extrusion groove 204 and the jacking column 205 are on the same horizontal line and disengage, the pressure block 210 contacts the rolled chromium metal target. Figure 7 As shown, the pressure block 210 rotates in the direction of the deflection groove 208, which reduces wear on the surface of the disc chromium target and reduces defects on the surface of the disc chromium target. When the pressure block 210 is completely separated from the disc chromium target, the pressure block 210 is reset by the elasticity of the torsion spring.

[0054] Furthermore, a sliding groove 211 is provided inside the roller 202, and an ejector ring 212 is slidably disposed within the sliding groove 211. A spring 213 is connected to the corresponding surface of the ejector ring 212 and the sliding groove 211. The spring 213 is used to drive the ejector ring 212 to return to its original position. Figure 7As shown, when the pressure block 210 and the ejection ring 212 are in contact, the pressure block 210 drives the ejection ring 212 to slide along the sliding groove 211. When the pressure block 210 and the ejection ring 212 are on the same horizontal line, the pressure block 210, through its cooperation with the ejection ring 212, rolls the metallic chromium powder into a disc metallic chromium target. The pressure block 210 and the ejection ring 212 are detachable. According to production requirements, by changing the shape of the pressure block 210 and the ejection ring 212, metallic chromium targets of different shapes can be rolled out. When the spring 213 drives the ejection ring 212 to reset, the inner wall of the ejection ring 212 rubs against the metallic chromium target, which accelerates the separation of the metallic chromium target from the bottom of the extrusion groove 204 and reduces the adhesion between the metallic chromium target and the bottom of the extrusion groove 204.

[0055] When rolling metallic chromium powder into a metallic chromium target, the pressing block 210 and the ejector ring 212 on the extrusion mechanism 2 work together to roll the metallic chromium powder into a disc-shaped metallic chromium target. At the same time, the pressing block 210 rotates to polish the disc-shaped metallic chromium target, improving the surface flatness of the disc-shaped metallic chromium target. When the pressing block 210 and the ejector ring 212 are on the same horizontal line and separate, the pressing block 210 rotates in the direction of the deflection groove 208 to reduce wear on the surface of the disc-shaped metallic chromium target.

[0056] Example 2 further optimizes the automatic forming and rolling device for disc-shaped chromium metal targets provided in Example 1. Specifically, as follows: Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the discharge mechanism 3 includes a first conveyor shaft 301 and a second conveyor shaft 302 rotatably disposed inside the housing 1. Both the first conveyor shaft 301 and the second conveyor shaft 302 are equipped with pulleys 303, and a conveyor belt 304 is disposed between the two pulleys 303. The conveyor belt 304 is designed to be inclined. When the first conveyor shaft 301 rotates, the pulleys 303 on the first conveyor shaft 301 rotate synchronously. The pulleys 303 drive the conveyor belt 304 to rotate synchronously, and the conveyor belt 304 drives the second conveyor shaft 302 to rotate synchronously. When the disc-shaped chromium metal target falls from the extrusion groove 204 onto the conveyor belt 304 due to gravity, the conveyor belt 304 discharges the disc-shaped chromium metal target from the discharge hole 102. The conveyor belt 304 can buffer the falling disc-shaped chromium metal target and reduce the damage rate of the disc-shaped chromium metal target.

[0057] Furthermore, a gear 305 is rotatably mounted on the conveyor shaft 301, and a strip groove 306 is provided inside the housing 1. A rack 307 is slidably mounted on the strip groove 306. The rack 307 and the gear 305 are mutually adapted. A spring 308 is connected to the corresponding surface of the rack 307 and the strip groove 306. A ratchet 309 is provided on the conveyor shaft 301, and a pawl 310 is rotatably mounted on the gear 305. The pawl 310 and the rotating part of the gear 305 are connected by a torsion spring. The ratchet 309 and the pawl 310 are mutually adapted. When the roller 202 rotates, the extrusion groove 204 rotates synchronously, and the extrusion groove 204 extrudes the rack 307. The end of the rack 307 is wedge-shaped. Figure 9 As shown, when the extrusion groove 204 and the rack 307 come into contact, the rack 307 slides upward into the extrusion groove 204 and impacts the bottom of the extrusion groove 204, causing vibration inside the roller. This accelerates the falling of the disc-shaped chromium target material. Simultaneously, the vibration ensures that the chromium powder enters the extrusion groove 204 evenly, reducing voids within the extrusion groove and thus improving the quality of the disc-shaped chromium target material. When the rack 307 disengages from the extrusion groove 204, the extrusion groove 204 rotates and drives the rack 307 to return to its original position downwards. The rack 307 slides downwards and drives the gear 4 305 to rotate. The pawl 310 on the gear 4 305 drives the ratchet 309 to rotate. The ratchet 309 drives the conveyor shaft 1 301 to rotate synchronously. When the rack 307 slides upwards and drives the gear 4 305 to rotate, the pawl 310 on the gear 4 305 spins freely along the edge of the ratchet 309, and the ratchet 309 does not rotate.

[0058] Furthermore, the conveyor belt 304 is provided with filter holes 311, the bottom of the housing 1 is provided with receiving holes 312, and the housing 1 is provided with a conical ring 313. The metallic chromium powder and the disc metallic chromium target material falling on the conveyor belt 304 are screened through the filter holes 311, so that the metallic chromium powder enters the conical ring 313 through the filter holes 311 and is collected by the conical ring 313. When the disc metallic chromium target material falls on the conveyor belt 304 each time, it can vibrate the conveyor belt 304, which can accelerate the passage of metallic chromium powder through the filter holes 311. The staff can collect the metallic chromium powder through the receiving holes 312 to prevent the waste of metallic chromium powder.

[0059] The discharge mechanism 3 vibrates the roller 202, causing the chromium powder to be evenly distributed in the extrusion trough 204, improving the quality of the disc chromium target. At the same time, it buffers the disc chromium target that falls onto the conveyor belt 304, reducing the damage rate of the disc chromium target, and screens the chromium powder and disc chromium target to prevent waste of chromium powder.

[0060] The automatic forming and rolling device for disc-shaped chromium metal targets provided by this invention is used as follows:

[0061] In use, metallic chromium powder is placed into the feed hopper 101. The metallic chromium powder slides down the feed hopper 101 into the extrusion groove 204. The motor 201 is started, and the output end of the motor 201 drives the first roller 202 to rotate. The extrusion groove 204 on the first roller 202 rotates synchronously. The extrusion groove 204 squeezes the pusher column 205, causing the pusher column 205 to rotate together with the second roller 203. When the pressure block 210 on the pusher column 205 contacts the ejector ring 212, the pressure block 210 drives the ejector ring 212 to slide along the sliding groove 211. When the pressure block 210 and the ejector ring 212 are on the same horizontal line, the pressure block 210, through its cooperation with the ejector ring 212, rolls the metallic chromium powder into a disc metallic chromium target. The extension 207 blocks the metallic chromium powder in the extrusion groove 204, reducing the amount of metallic chromium powder falling out of the extrusion groove 204. Simultaneously, the gear ring 2065 inside the roller 203 rotates synchronously, driving the gear 3 2067 to rotate, which in turn drives the gear 2064 to rotate. The gear 2064 then drives the rotating shaft 2061 and the gear ring 2062 to rotate synchronously. The gear ring 2062 drives the gear 2063 to rotate, which in turn drives the top column 205 to rotate synchronously. When the pressure block 210 and the extrusion groove 204 are on the same horizontal line, the rotating pressure block 210 rubs against the disc-shaped chromium metal target, polishing one end of the rolled disc-shaped chromium metal target, thereby improving the surface flatness of the disc-shaped chromium metal target and reducing the adhesion of chromium powder to the top column 205. When the pressure block 210 separates from the extrusion groove 204, the pressure block 210 contacts the rolled disc-shaped chromium metal target, such as... Figure 7As shown, the pressure block 210 rotates towards the deflection groove 208, thus reducing wear on the surface of the disc-shaped chromium target. Simultaneously, the extrusion groove 204 on the roller 202 extrudes the rack 307, whose end is wedge-shaped. When the extrusion groove 204 and the rack 307 contact, the rack 307 slides upwards into the extrusion groove 204 and impacts the bottom of the groove, causing vibration within the roller and accelerating the fall of the disc-shaped chromium target. Simultaneously, the vibration causes the metal... When chromium powder enters the extrusion groove 204, it can make the metallic chromium powder evenly distributed within the extrusion groove 204, reducing the presence of voids in the metallic chromium powder within the extrusion groove 204, thereby improving the quality of the disc metallic chromium target. When the rack 307 disengages from the extrusion groove 204, the extrusion groove 204 rotates and drives the rack 307 to return to its original position downwards. The rack 307 slides downwards and drives the gear four 305 to rotate. The pawl 310 on the gear four 305 drives the ratchet 309 to rotate, and the ratchet 309 drives... The conveyor shaft 301 rotates synchronously, which drives the pulley 303 to rotate synchronously. The pulley 303 drives the conveyor belt 304 to rotate synchronously, which in turn drives the conveyor shaft 302 to rotate synchronously. The conveyor belt 304 discharges the disc-shaped chromium metal target material from the discharge hole 102. When the rack 307 slides upward and drives the gear 305 to rotate, the pawl 310 on the gear 305 spins freely along the edge of the ratchet 309, causing the ratchet 309 to stop rotating and fall off due to vibration. The metallic chromium powder and the disc metallic chromium target on the conveyor belt 304 are screened, so that the metallic chromium powder enters the conical ring 313 through the filter hole 311. The metallic chromium powder is collected by the conical ring 313. When the disc metallic chromium target falls onto the conveyor belt 304 each time, it can vibrate the conveyor belt 304, which can accelerate the passage of metallic chromium powder through the filter hole 311. The workers can collect the metallic chromium powder through the receiving hole 312 to prevent the waste of metallic chromium powder.
