[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0025] The structure of the present utility model is described in detail below with reference to the accompanying drawings.
[0026] like Figures 1 to 6 As shown, an embodiment of the present invention provides a portable dry powder press, including a cabinet 1, a hydraulic mechanism 3 is provided on the cabinet 1, a linkage mechanism 2 is provided inside the hydraulic mechanism 3, the lower end of the linkage mechanism 2 is connected to a feeding mechanism 4, a plurality of forming holes 11 are provided on the cabinet 1, the feeding mechanism 4 is movably provided on the cabinet 1, and a top block 52 is movably inserted at the bottom of the forming hole 11.
[0027] Furthermore, the feeding mechanism 4 includes a storage tank 41, a feeding pipe 42 is fixedly connected to the bottom of the storage tank 41, the bottom of the feeding pipe 42 is fixedly connected to the pushing box 43, a cavity is provided at the bottom of the pushing box 43, and the feeding pipe 42 is connected to the cavity.
[0028] The storage tank 41 is used to store dry powder raw materials. During operation, the dry powder raw materials enter the cavity at the bottom of the pushing box 43 through the discharge pipe 42. The pushing box 43 moves under the drive of the linkage mechanism 2, pushing the dry powder in the cavity into the forming hole 11 to realize automatic loading. After hydraulic forming, it is ejected by the ejection block 52, and then the workpiece is pushed forward by the pushing box 43 to realize automatic unloading.
[0029] Furthermore, the hydraulic mechanism 3 includes a frame 31, which is fixedly connected to the upper surface of the cabinet 1. A hydraulic cylinder 32 is fixedly installed on the frame 31, and the output end of the hydraulic cylinder 32 is fixedly connected to a lifting frame 33. The four corners of the lifting frame 33 are slidably mounted on the guide rod 36. The upper and lower ends of the guide rod 36 are respectively fixedly connected to the top inner wall of the frame 31 and the upper surface of the cabinet 1. A mold base 34 is fixedly installed on the lower surface of the lifting frame 33, and a number of molds 35 are fixedly installed on the mold base 34.
[0030] In the present application, the hydraulic cylinder 32 drives the lifting frame 33 to slide up and down along the guide rod 36, and the die base 34 below the lifting frame 33 moves synchronously with it, so that the die 35 on the die base 34 enters the forming hole 11 accordingly, and the dry powder pressing is completed by the pressure of the hydraulic cylinder 32. The guide rod 36 plays a guiding and limiting role in the sliding of the lifting frame 33, ensuring that the die 35 and the forming hole 11 are accurately aligned, avoiding offset during pressing and causing the workpiece to be scrapped. The hydraulic cylinder 32 provides stable and adjustable pressure, which can adapt to the pressing requirements of different dry powder materials and improve the versatility of the device.
[0031] Furthermore, the jacking block 52 is fixedly mounted on the mounting plate 51 , the mounting plate 51 is fixedly connected to the output end of the jacking cylinder 5 , and the jacking cylinder 5 is fixedly mounted in the cabinet 1 .
[0032] The ejector block 52 corresponds to the forming hole 11. After the pressing is completed, the lifting cylinder 5 extends to push the mounting plate 51 upward, and the ejector block 52 ejects the workpiece in the forming hole 11. Then the cylinder contracts and resets. Through the mutual cooperation between the lifting cylinder 5 and the hydraulic cylinder 32, the demoulding and pressing processes are seamlessly connected, shortening the production cycle and improving production efficiency.
[0033] Furthermore, the linkage mechanism 2 includes an installation box 21, which is fixedly installed on the upper surface of the cabinet 1. A reciprocating screw rod 22 is rotatably installed in the installation box 21. A threaded sleeve 23 is threaded on the reciprocating screw rod 22, and the threaded sleeve 23 is slidably connected to the installation box 21. The threaded sleeve 23 is fixedly connected to one side of the pushing box 43. One end of the reciprocating screw rod 22 is fixedly connected to a lower transmission wheel 24, and an upper transmission wheel 26 is synchronously connected to the upper part of the lower transmission wheel 24 through a transmission belt 25. A gear 27 is coaxially fixedly connected to one side of the upper transmission wheel 26. The gear 27 is rotatably installed on a fixed frame 29, and the fixed frame 29 is fixedly connected to the side wall of the frame 31. A rack 28 is slidably connected to the inside of the fixed frame 29, and the rack 28 is meshed with the gear 27. The upper end of the rack 28 is fixedly connected to the lifting frame 33.
[0034] When the lifting frame 33 rises or falls, it drives the rack 28 to slide along the fixed frame 29, and the rack 28 engages with the gear 27 to rotate the gear 27. The gear 27 drives the upper transmission wheel 26, which drives the lower transmission wheel 24 and the reciprocating screw 22 to rotate through the transmission belt 25. The threaded sleeve 23 on the reciprocating screw 22 drives the push box 43 to slide back and forth in the installation box 21, realizing the linkage of feeding and pressing actions.
[0035] Specifically, when the lifting frame 33 is descending, the reciprocating screw 22 drives the pushing box 43 to move forward, pushing the dry powder into the forming hole 11, and continues to descend. The reciprocating screw 22 drives the pushing box 43 to move backward to avoid obstructing the mold 35. Then the mold 35 is gradually pressed into the forming hole 11. After pressing and molding, the mold 35 rises with the lifting frame 33, and the reciprocating screw 22 rotates in the opposite direction, driving the pushing box 43 to move forward first. The lifting cylinder 5 pushes out the workpiece, and the pushing box 43 pushes the workpiece forward to realize unloading, and then moves backward to reset.
[0036] By setting up the linkage mechanism 2, it is convenient to automatically adjust the position of the feeding mechanism 4, realize the coordinated cooperation of automatic feeding-hydraulic forming-automatic unloading, effectively reduce energy consumption, eliminate the need to wait between steps, and improve the smoothness and work efficiency of equipment operation.
[0037] The working principle of this utility model:
[0038] During operation, the dry powder in the storage tank 41 enters the cavity of the pushing box 43 through the discharge pipe 42, and the hydraulic cylinder 32 drives the lifting frame 33 to descend along the guide rod 36, driving the die base 34 and the die 35 to approach the forming hole 11. At the same time, the lifting frame 33 is linked to the pushing box 43 through the rack 28, gear 27, transmission wheel and reciprocating screw 22 to push the dry powder into the forming hole 11. Then the pushing box 43 moves backward, and the die 35 enters the forming hole 11 accordingly. The dry powder is pressed by the pressure of the hydraulic cylinder 32. After the pressing is completed, the lifting frame 33 rises and resets, and the pushing box 43 moves forward. At the same time, the lifting cylinder 5 drives the ejecting block 52 to rise, and the formed workpiece is ejected from the forming hole 11. The pushing box 43 pushes the workpiece out and resets after unloading, completing a pressing cycle.
[0039] To sum up: this adjustable dry powder press mechanically links the hydraulic pressing with the loading and unloading actions through the linkage mechanism 2, realizes the synchronization of the processes, reduces the non-production waiting time, and has higher production efficiency than the traditional step-by-step operation device. It integrates automatic loading, pressing, and unloading functions, reduces manual intervention, and reduces energy consumption.
