The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0037] like Figures 1 to 4 As shown, a copper powder pressing device 10 of an embodiment includes a frame (not shown), an upper pressing assembly 200 and a lower pressing assembly 300, wherein the frame (not shown) includes a fixed frame 110 and a workbench 120; the fixed frame 110 is arranged on the workbench 120; the upper pressing assembly 200 includes a first servo motor 210, a first guide seat 220 and a first pressing die seat 230; the first guide seat 220 is movably arranged on the fixed frame 110; the first end of the first guide seat 220 is connected to the first pressing die seat 230, and the second end of the first guide seat 220 is connected to the driving end of the first servo motor 210; the first pressing die seat 230 is connected to the first pressing die seat 23 ... A plurality of first stamping columns 231 are formed on one side of the clamping die seat 230 facing the workbench 120; the pressing assembly 300 includes a second servo motor 310, a second guide seat 320 and a second clamping die seat 330; the second guide seat 320 is located below the first guide seat 220 and is movably arranged below the fixed frame 110; the second end of the second guide seat 320 is connected to the second clamping die seat 330, and the second end of the second guide seat 320 is connected to the driving end of the second servo motor 310; a plurality of second stamping columns 331 are formed on one side of the second clamping die seat 330 facing the first clamping die seat 230.

[0038] It can be understood that the fixed frame 110 is arranged on the workbench 120, and the workbench 120 plays a role of fixing and supporting the fixed frame 110; since the first guide seat 220 is movably arranged on the fixed frame 110, the first guide seat 220 can move up and down on the fixed frame 110; and since the first end of the first guide seat 220 is connected to the first pressing mold seat 230, and the second end of the first guide seat 220 is connected to the driving end of the first servo motor 210, the first servo motor 210, the first guide seat 220 and the first pressing mold seat 230 are connected and arranged in sequence from top to bottom; when the first servo motor 210 is started, the first servo motor 210 drives the first guide seat 220 to move up and down, thereby driving the first pressing mold seat 230 to move; since the first pressing mold seat 230 is formed with a plurality of first stamping columns 231 on the side facing the workbench 120, the plurality of first stamping columns 231 can be driven to move toward the direction of the workbench 120. Similarly, since the second guide seat 320 is located below the first guide seat 220 and is movably arranged below the fixing frame 110; the first end of the second guide seat 320 is connected to the second pressing die seat 330, and the second end of the second guide seat 320 is connected to the driving end of the second servo motor 310, the second servo motor 310, the second guide seat 320 and the second pressing die seat 330 of the pressing assembly 300 are sequentially arranged and connected from bottom to bottom. When the second servo motor 310 is started, the second guide seat 320 is driven to move up and down, thereby driving the multiple second stamping columns 331 of the second pressing die seat 330 to move; since the multiple second stamping columns 331 are arranged corresponding to the multiple first stamping columns 231, the first servo motor 310 210 drives the multiple first punching columns 231 on the first pressing die seat 230 to press downward, and the second servo motor 310 drives the multiple second punching columns 331 on the second pressing die seat 330 to press upward, so as to complete the pressing operation of the copper cake; that is, the first servo motor 210 and the second servo motor 310 independently control the movement of the first pressing die seat 230 and the second pressing die seat 330, so that the operator can adjust the speed of the first servo motor 210 and the second servo motor 310 to run independently, and further realize the uniformity of the force at both ends of the first pressing die seat 230 and the first pressing die seat 230, thereby avoiding the problem of uneven force on the upper end when the traditional cylinder presses copper powder, resulting in uneven pressing of the upper end surface of the copper cake, and further improving the production quality of the copper cake.

[0039] Furthermore, since the first servo motor 210 and the second servo motor 310 independently control the movement of the first pressing die base 230 and the second pressing die base 330, when the first servo motor 210 or the second servo motor 310 fails, the pressing operation of the copper cake can still be completed by adjusting the appropriate pressing speed, effectively avoiding the phenomenon that the one-way drive is shut down due to the failure of the driving source to affect production.

[0040] Furthermore, since the servo motor has better operating stability than the cylinder drive source, the present invention uses the first servo motor 210 and the second servo motor 310 to provide a stable pressing force for the first pressing die seat 230 and the second pressing die seat 330, effectively avoiding the problem of uneven force on the copper cake causing the uneven upper end surface of the copper cake, thereby ensuring the product quality of the copper cake.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the fixing frame 110 includes a first fixing plate 111, a second fixing plate 112 and a first guide column 113; the first fixing plate 111 is connected to the second fixing plate 112 through the first guide column 113; the first fixing plate 111 is located above the workbench 120, the second fixing plate 112 is arranged on the workbench 120, and is arranged opposite to the first fixing plate 111; the first servo motor 210 is arranged on the first fixing plate 111; the first guide seat 220 is correspondingly formed with a plurality of first guide holes 221; the first guide seat 220 is slidably arranged on the first guide column 113 through the first guide hole 221.

[0042] It can be understood that since the first fixing plate 111 is connected to the second fixing plate 112 through the first guide column 113, the upper and lower ends of the first guide column 113 are respectively fixedly connected to the first fixing plate 111 and the second fixing plate 112, thereby ensuring the stability of the fixing frame 110; since the second fixing plate 112 is arranged on the workbench 120, the workbench 120 supports the second fixing plate 112, the first fixing plate 111 is located above the workbench 120, and the second fixing plate 112 is arranged on the workbench 120 and is arranged opposite to the first fixing plate 111; the first fixing plate 111 is realized The first fixing plate 111 and the second fixing plate 112 are arranged relatively to each other, so that the first fixing plate 111 and the second fixing plate 112 can form a pressing space, which is convenient for completing the pressing operation of the copper cake; since the first servo motor 210 is arranged on the first fixing plate 111, the first fixing plate 111 is used to support and fix the first servo motor 210 to prevent the first servo motor 210 from loosening due to vibration when starting; and since the first guide seat 220 is slidably arranged on the first guide column 113 through the first guide hole 221, the first guide seat 220 can slide up and down between the first fixing plate 111 and the second fixing plate 112.

[0043] Likewise, if Figure 1 and Figure 3As shown, in one embodiment, the second servo motor 310 is arranged on the side of the second fixed plate 112 facing away from the workbench 120; the workbench 120 is formed with a first movable hole; the second fixed plate 112 is formed with a second movable hole; the driving end of the second servo motor 310 passes through the first movable hole and the second movable hole in sequence, and the driving end of the second servo motor 310 is connected to the second guide seat 320; the second guide seat 320 is correspondingly formed with a plurality of second guide holes 321; the fixing frame 110 also includes a second guide column 114; the second guide seat 320 is slidably arranged on the second guide column 114 through the second guide hole 321.

[0044] It can be understood that the second servo motor 310 is arranged below the workbench 120, the second fixed plate 112 is arranged on the workbench 120, and the driving end of the second servo motor 310 passes through the first movable hole and the second movable hole in sequence to connect with the second guide seat 320; the second servo motor 310 can drive the second guide seat 320 to move up and down; because the second guide seat 320 is arranged on the second guide column 114 through the second guide sliding, the second guide seat 320 can slide well along the second guide column 114.

[0045] In one of the embodiments, the first guide column 113 is located at the outer periphery of the second fixed plate 112; the second guide column 114 is located inside the second fixed plate 112, so that the first guide column 113 and the second guide column 114 are not arranged in the same plane of the second fixed plate 112, on the one hand, the compactness of the structure is improved, and on the other hand, the first guide seat 220 and the second guide seat 320 are separately slidingly arranged to ensure that the sliding of the first guide seat 220 and the second guide seat 320 on the fixed frame 110 do not interfere with each other, and at the same time ensure that the sliding stroke of the first guide seat 220 and the second guide seat 320 on the fixed frame 110 is maximized, which is well adapted to the fact that when the first servo motor 210 or the second servo motor 310 fails, the other servo motor still has a larger sliding stroke to complete the pressing operation of the copper cake, effectively avoiding the phenomenon of shutdown caused by the failure of the first servo motor 210 or the second servo motor 310.

[0046] In one embodiment, the first guide seat 220 further includes a first guide ring 222, which is disposed in the first guide hole 221; the additional first guide ring 222 is protruding from the first guide hole 221, so that the first guide ring 222 can provide a better guide effect for the first guide column 113, thereby improving the sliding reliability of the first guide column 113. Similarly, in another embodiment, the second guide seat 320 further includes a second guide ring 322, which is disposed in the second guide hole 321, and the second guide ring 322 is protruding from the second guide hole 321, so that the second guide ring 322 can provide a better guide effect for the second guide column 114, thereby improving the sliding reliability of the second guide column 114.

[0047] In one embodiment, the number of the first guide posts 113 is plural; and / or the number of the second guide posts 114 is plural. Since the number of the first guide posts 113 is plural, the first guide seat 220 is correspondingly formed with a plurality of first guide holes 221, and each first guide hole 221 is arranged in a one-to-one correspondence with each first guide post 113; similarly, since the number of the second guide posts 114 is plural, the second guide seat 320 is correspondingly formed with a plurality of second guide holes 321, and each second guide hole 321 is arranged in a one-to-one correspondence with each second guide post 114.

[0048] Preferably, there may be four first guide posts 113 and second guide posts 114, which can ensure the support of the first guide seat 220 and the second guide seat 320 for sliding, and simplify the structure of the device and reduce the manufacturing cost.

[0049] like Figure 1 As shown, in one embodiment, the second pressing die seat 330 is formed with a powder placement groove 333 toward the first pressing die seat 230, and the inner wall of the powder placement groove 333 is formed with a plurality of forming holes 333a. The powder placement groove 333 is used to hold copper powder, and the inner wall of the powder placement groove 333 is formed with a plurality of forming holes 333a. The plurality of forming holes 333a, the plurality of first punching columns 231, and the plurality of second punching columns 331 are arranged one by one in correspondence. The first punching columns 231 are pressed into the upper end surface of the copper powder in the forming hole 333a, and the second punching columns 331 are pressed into the lower end surface of the copper powder in the forming hole 333a, so as to realize the production of copper cakes, and at the same time, the copper powder in the plurality of forming holes 333a is pressed, thereby improving the production efficiency of the copper cakes.

[0050] like Figure 4As shown, in one embodiment, a plurality of positioning posts 232 are formed on the first pressing die seat 230 toward the second pressing die seat 330, and a plurality of positioning holes 332 are formed on the second pressing die seat 330 toward the first pressing die seat 230; each of the positioning posts 232 is arranged in a one-to-one correspondence with each of the positioning holes 332. It can be understood that the plurality of positioning posts 232 on the first pressing die seat 230 and the plurality of positioning holes 332 on the second pressing die seat 330 are adapted to each other. When bidirectional pressing of copper powder is performed, the plurality of positioning posts 232 and the plurality of positioning holes 332 can be positioned to avoid displacement of the positions of the first pressing die seat 230 and the second pressing die seat 330 during pressing, thereby improving the pressing efficiency. Specifically, there can be two positioning posts 232 and two positioning holes 332.

[0051] In one embodiment, the positioning column 232 includes a metal part and an elastic buffer part connected to each other, and the metal part is connected to the second pressing mold seat 330. The metal part of the positioning column 232 is connected to the second pressing mold seat 330 to improve the stability and wear resistance of the positioning column 232, and the elastic buffer part of the positioning column 232 plays a role of shock absorption and buffering, reducing the wear of the positioning column 232 and the second pressing mold seat 330.

[0052] In one embodiment, the copper powder pressing device 10 further includes a buffer rubber pad 400; the buffer rubber pad 400 is disposed below the second guide seat 320. When the second guide seat 320 slides downward, the bottom of the second guide seat 320 conflicts with the workbench 120, and the additional buffer rubber pad 400 effectively avoids direct contact between the bottom of the second guide seat 320 and the workbench 120, plays a buffering role, and reduces the wear of the bottom of the second guide seat 320 and the workbench 120.

[0053] In one embodiment, a support frame 500 is disposed below the second guide seat 320 , and the support frame 500 is used to support the second servo motor 310 to avoid the second servo motor 310 from loosening due to vibration during startup, thereby improving the stability of the pressing.

[0054] The present disclosure also provides a copper powder pressing molding device, including the copper powder pressing device 10 described in any of the above embodiments. In one embodiment, the copper powder pressing molding device also includes an ejection component, which is arranged below the powder placing groove 333 and is used to eject the formed copper cake from the forming hole 333a of the powder placing groove 333.

[0055] Compared with the prior art, the present invention has at least the following advantages:

[0056] 1. Since the servo motor has better operating stability than the cylinder drive source, the first servo motor 210 and the second servo motor 310 used in the present invention can provide a stable pressing force for the first pressing die seat 230 and the second pressing die seat 330, effectively avoiding the problem of uneven force on the copper cake causing the uneven upper end surface of the copper cake, thereby ensuring the product quality of the copper cake.

[0057] 2. Since the first end of the first guide seat 220 is connected to the first pressing mold seat 230, and the second end of the first guide seat 220 is connected to the driving end of the first servo motor 210, the driving connection between the first servo motor 210 and the first guide seat 220 is realized, so that the first guide seat 220 can drive the first pressing mold seat 230 to move back and forth under the action of the first servo motor 210; and since the second guide seat 320 is located below the first guide seat 220 and is movably arranged below the fixing frame 110; the first end of the second guide seat 320 is connected to the second pressing mold seat 330, and the second end of the second guide seat 320 is connected to the driving end of the second servo motor 310. The movable end enables the second guide seat 320 to drive the second pressing die seat 330 and the first pressing die seat 230 to perform a pressing operation under the action of the second servo motor 310 to complete the operation of pressing the copper powder; that is, the first servo motor 210 and the second servo motor 310 independently control the movement of the first pressing die seat 230 and the second pressing die seat 330, so that the operator can adjust the speed of the first servo motor 210 and the second servo motor 310 to run independently, and further realize the uniformity of the force on both ends of the first pressing die seat 230 and the first pressing die seat 230, thereby avoiding the problem of uneven pressure on the upper end of the copper cake when the traditional cylinder presses the copper powder, thereby further improving the production quality of the copper cake.

[0058] 3. Since the first servo motor 210 and the second servo motor 310 independently control the movement of the first pressing die base 230 and the second pressing die base 330, when the first servo motor 210 or the second servo motor 310 fails, the pressing operation of the copper cake can still be completed by adjusting the appropriate pressing speed, effectively avoiding the phenomenon that the one-way drive is shut down due to the failure of the driving source to affect production.

[0059] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
