For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In view of the technical problems described in the background art, as shown in Figures 1-12, a transverse powder forming machine is provided, comprising: a frame 1 for mounting and supporting mechanical components; an upper punch 2 mounted on the frame 1 for pressing powder into shape; a lower punch 3 mounted on the frame 1 and positioned below the upper punch 2, the lower punch 3 cooperating with the upper punch 2 to move relative to each other to press the powder; a worktable 4 mounted on the frame 1 and positioned between the upper punch 2 and the lower punch 3; a transverse pressing device 5, comprising two or more sets of transverse pressing devices mounted on the worktable 4 and arranged opposite to each other, each transverse pressing device 5 including a linear drive 6 and a forming block 7 disposed on the output end of the linear drive 6; wherein the forming block 7 is driven by the linear drive 6 to assemble into a chamber for containing powder; and a control system 8 for receiving and outputting signals.

[0034] In the above, the frame 1 supports the various functional modules and can be configured according to specific usage. The upper punch 2 is installed on the upper part of the frame 1, and the lower punch 3 is located below the upper punch 2. The relative movement of the upper punch 2 and the lower punch 3 presses the powder. The worktable 4 is installed between the upper punch 2 and the lower punch 3. At least two horizontal pressing devices 5 are installed on the worktable 4 in the horizontal direction. The horizontal pressing devices 5 are arranged opposite each other. Each horizontal pressing device 5 includes a linear drive 6 and a forming block 7. The linear drive 6 is mainly used to drive the forming block 7 to move horizontally. The forming block 7 has corresponding notches 9 for assembling to form a cavity. In use, the linear drive 6 drives the forming block 7 to move linearly and assemble to form a cavity for placing powder. The cavity is designed according to the shape of the workpiece to be produced.

[0035] The specific usage process is as follows: the linear drive 6 drives the forming block 7 to move relative to each other to form a cavity for placing powder. At the same time, the lower punch 3 drives to seal the lower end of the cavity. Under the drive of the powder feeding device, the powder is filled into the cavity. Then, the upper punch 2 and the lower punch 3 drive relative to each other, and cooperate with the transverse pressing device 5 to press and form the required workpiece. Then, the transverse pressing device 5 retracts along the forming direction, the upper punch 2 moves up to reset, and the lower punch 3 drives upward to push the workpiece out, thus completing the entire operation process.

[0036] By adopting the above technical solution, multi-directional synchronous pressing is achieved through the synergistic effect of the transverse pressing device 5 and the upper and lower punching devices 3, which significantly improves the uniformity of powder molding density and is especially suitable for molding parts with complex cross-sectional shapes. The adjustable notch 9 splicing structure of the molding block 7 can be quickly adapted to various chamber specifications by changing modules with different notch 9 shapes, reducing mold modification costs.

[0037] Preferably, there are four sets of transverse pressing devices 5, which are evenly distributed in a circular array on the worktable 4. In this embodiment, four sets of transverse pressing devices 5 are used, and a cavity is formed by assembling the front ends of four forming blocks 7.

[0038] Referring to Figure 7, the linear drive 6 is an electric cylinder module, and the top of the molding block 7 away from the linear drive 6 is provided with a notch 9. The notch 9 and the notch 9 of the other molding block 7 are combined to form a cavity.

[0039] As a feasible technical solution, the linear drive component 6 can be an electric cylinder module, or of course a hydraulic cylinder module or a pneumatic cylinder module, etc.; the notch 9 on the top of the forming block 7 is designed according to the shape of the workpiece and can be adapted to the actual production product.

[0040] As shown in Figure 6, this utility model includes a linear guide module 10, which is respectively disposed between the worktable 4 and the forming block 7. The linear guide module 10 is used to guide the movement of the forming block 7.

[0041] To ensure accurate movement of the forming block 7, a linear guide module 10 is installed between the forming block 7 and the worktable 4. The number of linear guide modules 10 can be arranged as needed. Preferably, two sets of linear guide modules 10 are used in this embodiment. When the forming block 7 is driven by the electric cylinder module, the linear guide module 10 guides it.

[0042] Referring to Figures 8-9, the upper punch device 2 includes an upper punch motor 11, an upper punch screw 12 connected to the output end of the upper punch motor 11, a first guide column group 13 arranged parallel to the upper punch screw 12, a fixing plate 14 connected to the frame 1, an upper punch head 15 sleeved on the upper punch screw 12 and the first guide column group 13, and an upper punch guide plate 16 sleeved on the lower end of the upper punch head 15; the upper punch guide plate 16 is placed below the fixing plate 14, and the two ends of the first guide column group 13 are respectively connected to the frame 1 and the fixing plate 14; the upper punch motor 11 drives the upper punch head 15 to move longitudinally along the first guide column group 13.

[0043] The above provides an implementable upper punch device 2 structure, which includes an upper punch motor 11, an upper punch lead screw 12, a first guide post assembly 13, a fixing plate 14, an upper punch head 15, and an upper punch guide plate 16. The output end of the upper punch motor 11 can be connected to the upper punch lead screw 12 via a coupling. The first guide post assembly 13 consists of four posts. The upper end of the upper punch head 15 has an internal thread, and the upper punch head 15 is threaded onto the upper punch lead screw 12. A connecting plate is provided along the circumferential surface of the upper end of the upper punch head 15, and the connecting plate is fitted onto the first guide post assembly 13. The lower end of the upper punch head 15 is fitted with the upper punch guide plate 16. The first guide post assembly 13 guides and bears the load during the longitudinal movement of the upper punch head 15, preventing deformation of mechanical parts and affecting operating accuracy.

[0044] The specific driving process is as follows: the upper punch motor 11 drives the upper punch screw 12 to rotate. Since the upper punch head 15 is sleeved on the upper punch screw 12 and the first guide column group 13, under the limitation of the two, the upper punch head 15 moves longitudinally along the first guide column group 13 to perform the pressing operation.

[0045] As shown in Figure 3, this utility model includes a second guide post group 17, which connects the fixed plate 14 and the worktable 4 respectively; wherein, the second guide post group 17 passes through the upper punch guide plate 16, and the upper punch guide plate 16 moves longitudinally along the second guide post group 17.

[0046] The second guide post group 17 consists of four posts. The second guide post group 17 is used to further guide the upper punch guide plate 16 and improve the movement accuracy of the upper punch 15. At the same time, the second guide post group 17 can provide overall structural strength and distribute the load.

[0047] Referring to Figures 10-12, the lower punch device 3 includes a lower punch motor 18, a lower punch screw 19 connected to the output end of the lower punch motor 18, a third guide column group 20 arranged parallel to the lower punch screw 19, a lower punch head 21 sleeved on the lower punch screw 19, and a lower punch guide plate 22 sleeved on the third guide column group 20 and the lower punch head 21; the lower punch motor 18 drives the lower punch head 21 to move longitudinally along the third guide column group 20.

[0048] The above provides an implementable technical solution for the punching device 3, which includes a punching motor 18, a punching screw 19, a third guide post assembly 20, a punch head 21, and a punching guide plate 22. The output end of the punching motor 18 can be connected to the punching screw 19 via a coupling. The third guide post assembly 20 consists of four posts parallel to the punching screw 19. The lower end of the punch head 21 has an internal thread, and the punch head 21 is threaded onto the punching screw 19. The punching guide plate 22 is fitted onto the circumferential surface of the punch head and is mounted on the third guide post assembly 20.

[0049] The driving process is as follows: the lower punch motor 18 drives the lower punch screw 19 to rotate, and the lower punch 21 moves longitudinally along the third guide post group 20 under the limit of the lower punch screw 19 and the third guide post group 20. The third guide post group 20 guides and bears the load during the longitudinal movement of the lower punch 21, avoiding deformation of mechanical parts and affecting the running accuracy.

[0050] Preferably, the present invention includes a support column assembly 23, which is disposed between the punch motor 18 and the frame 1.
