Description

Technical Field

[0001] This utility model relates to the field of powder forming equipment technology, and in particular to a powder forming machine with a simplified structure. Background Technology

[0002] A powder forming machine is a device used to press metal or non-metal powders into blanks of a specific shape and density. The powder is filled into the mold cavity through a feeder. The upper punch presses down (or applies pressure in both directions), binding the powder together. Maintaining pressure makes the powder bond more tightly, reducing elastic recovery. The blank is ejected, completing the forming process.

[0003] The lower die transmission structure of existing powder molding machines on the market is usually in the form of motor + lead screw + connecting plate + guide shaft + mold frame. When there are multiple sets of lower die components, the transmission path of the lower die is complex, which results in a large amount of longitudinal space being occupied, making the equipment taller and increasing production costs.

[0004] Therefore, improvements are needed. Utility Model Content

The control system 2 can be a PLC system, CNC system, etc. to receive and output signals, and there are no restrictions on this.

[0042] The upper punch assembly 3 is used to drive downward pressure and cooperate with the lower punch assembly to press the powder into shape. Preferably, the upper punch assembly 3 includes an upper punch motor 4, an upper punch screw 5, an upper punch optical shaft 6, an upper punch head 7, a fixing plate 8, and a guide plate 9.

The upper punch head 7 is connected to the upper punch screw 5 by the thread, and the outer part of the upper punch head 7 is sleeved on the upper punch optical shaft 6. When the upper punch motor 4 drives the upper punch screw 5 to rotate, the upper punch head 7 moves downward under the limit of the upper punch screw 5, and the lower end of the upper punch head 7 presses the powder.

[0043] The fixed seat 10 is a load-bearing component during pressing. The fixed seat 10 is fixedly installed on the frame 1, and a fixed mandrel 11 is set at the center of the upper end face of the fixed seat 10. The fixed mandrel 11 has a hollow structure, which facilitates its cooperation with the next punch mandrel 18, the second punch mandrel 25 and the third punch mandrel 31 to form the required workpiece shape.

[0044] The first guide post group 12 uses four posts to connect the fixing plate 8 and the fixing seat 10 respectively, which can guide the guide plate 9 and the second base plate 17.

The first motor 45 and the first lead screw 14 can be connected by a reducer or a coupling. In practice, two first motors 45 are used, and the two first motors 45 are respectively connected to the first lead screw 14. The first drive shaft 15 is sleeved on the first lead screw 14. The lower section of the first drive shaft 15 is provided with an internal thread. The first drive shaft 15 is sleeved on the first lead screw 14. Since the first base plate 16 and the second base plate 17 are both mounted on the first drive shaft 15, the first base plate 16 and the second base plate 17 can be driven to move longitudinally. A lower punch rod 18 is mounted on the upper surface of the first substrate 16. The lower punch rod 18 is a solid mandrel used to form the through-hole shape of the workpiece. The lower punch rod 18 extends from the first substrate 16 to the working area 19 of the second substrate 17. The fixing mandrel 11 of the fixing seat 10 also extends to the working area 19. The working area 19 is used for filling powder and demolding the pressed workpiece. That is, when the lower punch assembly 13 is driven, it drives the first substrate 16 and the second substrate 17 to move longitudinally.

[0046] The lower two-stroke assembly 20 is used in conjunction with the upper two-stroke assembly 3 and the lower two-stroke assembly 13 to press and form a workpiece with a stepped structure. The lower two-stroke assembly 20 includes a second motor 21, a second lead screw 22, a second transmission shaft 23, a third base plate 24, and a lower two-stroke mandrel 25. The second motor 21 and the second lead screw 22 can be connected by a reducer or a coupling.

The second transmission shaft 23 is sleeved on the second lead screw 22. The lower section of the second transmission shaft 23 has an internal thread. Since the third base plate 24 is mounted on the second transmission shaft 23, it can drive the third base plate 24 to move longitudinally. The lower two-stroke mandrel 25 is mounted on the upper surface of the third substrate 24. The lower two-stroke mandrel 25 is a hollow mandrel used to form the stepped structure of the workpiece. The outer wall of the lower two-stroke mandrel 25 is in contact with the inner wall of the fixed mandrel 11. The step is formed by the height difference between the lower two-stroke mandrel 25 and the fixed mandrel 11. The lower two-stroke mandrel 25 extends to the working area 19.

[0047] The lower three-punch assembly 26 is used in conjunction with the upper punch assembly 3, the lower punch assembly 13, and the lower two-punch assembly 20 to press and form a workpiece with a stepped structure. The lower three-punch assembly 26 includes a third motor 27, a third lead screw 28, a third drive shaft 29, a fourth base plate 30, and a lower three-punch mandrel 31. The third motor 27 and the third lead screw 28 can be connected by a reducer or a coupling. In practice, two third motors 27 are used, and the two third motors 27 are respectively connected to the third lead screw 28. The third drive shaft 29 is sleeved on the third lead screw 28. The lower section of the third drive shaft 29 has an internal thread. Since the fourth base plate 30 is mounted on the third drive shaft 29, it can drive the fourth base plate 30 to move longitudinally.

The step is formed by the height difference between the lower three-stroke mandrel 31 and the lower two-stroke mandrel 25. The lower three-stroke mandrel 31 extends to the working area 19.

[0048] The powder feeding device 32 is used to fill the working area 19 with powder.

[0049] In its specific use: the lower punch assembly 13, the lower second punch assembly 20, and the lower third punch assembly 26, according to the required workpiece structure, drive the lower punch mandrel 18, the lower second punch mandrel 25, and the lower third punch mandrel 31 to form a height difference. The powder feeding device 32 feeds powder to fill the space formed between the working area 19 and the lower punch mandrel 18, the lower second punch mandrel 25, and the lower third punch mandrel 31. Then, the upper punch assembly 3 is driven to press down. The upper punch assembly 3, together with the lower punch assembly 13, the lower second punch assembly 20, and the lower third punch assembly 26, presses the powder together to form a workpiece. Then, the upper punch assembly 3 resets, and the lower punch mandrel 18, the lower second punch mandrel 25, and the lower third punch mandrel 31 are driven to push the workpiece out. At this time, the lower punch mandrel 18, the lower second punch mandrel 25, and the lower third punch mandrel 31 are at the same horizontal plane as the working area 19.

[0050] In the above, by designing the lower die assembly (lower punch assembly 13, lower second punch assembly 20, lower third punch assembly 26) as a coaxial nested structure with independent motor drive and lead screw transmission, it is directly connected to the base plate, eliminating the need for complex transmission components such as traditional connecting plates and guide shafts, greatly reducing the vertical space occupation and effectively reducing the overall height of the equipment.

[0051] refer to Figure 17-18 As shown, the powder feeding device 32 includes a housing 33, a powder feeding motor 34 disposed in the housing 33, a reducer connected to the output shaft of the first motor 45, a swing arm 35 connected to the reducer, a bracket 36 hanging on the swing arm 35, a box 37 disposed on the bracket 36, and a cylinder 38 disposed outside the housing 33; an open slot 39 is provided at the connection position between the bracket 36 and the swing arm 35, and the telescopic end of the cylinder 38 is hung on the bracket 36.

[0052] The powder feeding device 32 is used to quantitatively feed powder into the space formed by the working area 19, the next punch 18, the second punch 25, and the third punch 31. To facilitate easy disassembly, the powder feeding device 32 includes: a housing 33, a powder feeding motor 34, a reducer, a swing arm 35, a bracket 36, a box 37, and a cylinder 38. The housing 33 is equipped with drive switches, such as switches for the powder feeding motor 34 and the cylinder 38. The powder feeding motor 34 is located inside the housing 33, and its output end is connected to the reducer. The other output end of the reducer extends outside the housing 33 and is connected to the swing arm 35. Meanwhile, the bracket 36 is designed with an open slot 39, which is a downward-facing U-shaped slot. The bracket 36 is directly attached to the swing rod 35, and the telescopic end of the cylinder 38 is attached to the bracket 36. At the same time, when the powder box is being fed, the cylinder 38 continuously presses down, and the powder box can effectively fit against the end face of the working area 19.

[0053] like Figure 19As shown, the working area 19 is provided with upwardly protruding limiting edges 40 on both sides along the moving direction of the powder feeding device 32. The limiting edges 40 are used to limit the two sides of the box body 37.

[0054] By setting limiting edges 40 on both sides of the working area 19, the height of the protrusion of the limiting edges 40 can be selected according to the actual implementation. The limiting edges 40 can guide the movement of the box 37 and also block the powder, preventing the powder from entering some mechanical parts, such as the guide column assembly, which would damage the guiding accuracy.

[0055] Preferably, the limiting edge 40 is provided with a baffle 41 on the outer side of the box body 37, and the baffle 41 is used to isolate the powder.

[0056] Furthermore, a baffle 41 is provided, the height of which is higher than that of the limiting strip, which can further block the powder and prevent the powder from entering some mechanical parts.

[0057] This utility model includes a partition 42, which is disposed on the fixed base 10. The partition 42 is attached to the inner wall of the frame 1 and divides the interior of the frame 1 into two spaces.

[0058] In practice, the interior of the frame 1 is a space that is connected in the longitudinal direction. In order to prevent powder from entering the lower punch assembly 13, the lower second punch assembly 20 and the lower third punch assembly 26 from the working area 19 and causing damage to the mechanical parts, a partition 42 is installed on the end face of the fixed seat 10. The partition 42 separates the positions of the upper punch assembly 3 and the lower punch assembly.

[0059] like Figure 6 As shown, the first guide post group 12 is provided with accordion-style protective covers 43 for isolating powder.

[0060] To further prevent powder from entering the first guide post assembly 12 and causing a disruption in the guiding accuracy, the first guide post assembly 12 is fitted with an accordion-style protective cover 43, which can protect the first guide post assembly 12 and prevent powder and other substances from entering the components of the first guide post assembly 12 and affecting the guiding accuracy.

[0061] refer to Figure 20 The present invention also includes a second guide post assembly 44 for guiding and sharing the load, the second guide post assembly 44 being respectively connected through the fixed base 10, the third base plate 24, the fourth base plate 30 and the second base plate 17.

[0062] The second guide post group 44 can provide guidance for the lower punch assembly 13, the lower second punch assembly 20 and the lower third punch assembly 26 during movement, thereby improving the movement accuracy. At the same time, during the pressing process of the upper punch assembly 3 and the lower punch assembly 13, the lower second punch assembly 20 and the lower third punch assembly 26, the load is shared and the mechanical component structure is not easily deformed.

[0063] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
