Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automated positioning and shaping technology for powder rods and slabs, specifically relating to a positioning and shaping device for high-density tungsten alloy powder rods and slabs. Background Technology
[0002] In traditional high-density tungsten alloy powder metallurgy production, the mixed high-density tungsten alloy powder requires a semi-manual process combining single-machine equipment and manual labor. This involves manual weighing, filling, compaction, and sealing with rubber stoppers, followed by cold isostatic pressing. Even after automatic filling production lines complete the material loading, manual labor is required to repeatedly ensure the material is positioned at the correct elevation for the pressing process. This process is not only inefficient and physically demanding, but also suffers from high labor intensity and inconsistent compaction uniformity during the compaction process, ultimately compromising product quality. The vibration process relies on manual manipulation of the mold, with the powder being held up and down to achieve compaction. If the powder is not compacted after being placed in the mold, it cannot be sealed with a rubber stopper. In the subsequent cold isostatic pressing process, the sealed mold is immersed in liquid, and under high pressure, the mold is uniformly compressed to form a billet for sintering. If the seal is not tight, the powder may escape from the mold while in the liquid, preventing the formation of the billet. In addition, it is necessary to control the density of the powder in the mold before isostatic pressing. If the compaction process is not carried out, it will affect the density of the billet after isostatic pressing, which will affect the product performance in the subsequent sintering process after isostatic pressing.
[0003] The existing production conditions and capacity are far from meeting current production needs. Technological upgrades are urgently needed, and working in a dusty workshop poses a significant health hazard to workers, with dust creating a substantial safety risk at certain densities.
[0004] Therefore, there is a need to provide a high-density tungsten alloy powder rod forming device. Utility Model Content
[0005] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing a high-density tungsten alloy powder rod shaping device. This device uses an ejector assembly to easily lift the rod containing high-density tungsten alloy powder for shaping, improving the shaping effect. Through the cooperation of the displacement assembly and the ejector assembly, the lifted rod containing high-density tungsten alloy powder enters the next guide sleeve for further shaping, thus achieving the desired shaping effect. It also automatically moves the rod containing high-density tungsten alloy powder to the left, completing the shaping and removing it from the shaping device. This achieves automated shaping, saves labor costs, and significantly improves the efficiency of shaping.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-density tungsten alloy powder rod pier shaping device, characterized in that the device includes a pier shaping base, a support platform is provided above the pier shaping base, multiple vibrating blocks are arranged in a straight line on the support platform, an ejection assembly that cooperates with the vibrating blocks is provided on the support platform, an upright bracket is provided on the support platform, a guide platform is installed on the upright bracket, multiple guide sleeves corresponding to the vibrating blocks are provided at the lower part of the guide platform, guide holes are opened at the positions corresponding to the guide sleeves on the guide platform, a displacement assembly is also provided on the support platform, the displacement assembly includes a displacement bracket installed on the support platform, a horizontal cylinder is provided on the displacement bracket, the output shaft of the horizontal cylinder is connected to a sliding platform, a movable sleeve corresponding to the multiple guide sleeves is provided at the lower part of the sliding platform, and a through hole is opened at the position corresponding to the movable sleeve on the sliding platform.
[0007] The above-mentioned high-density tungsten alloy powder rod shaping device is characterized in that the ejection assembly includes a vertical cylinder mounted on a support platform, a lifting platform fixed to the end of the output shaft of the vertical cylinder, and push rods that cooperate with multiple vibrating blocks mounted on the lifting platform.
[0008] The above-mentioned high-density tungsten alloy powder rod shaping device is characterized in that two sliding rods are also provided between the lifting platform and the support platform.
[0009] The above-mentioned high-density tungsten alloy powder rod shaping device is characterized in that a receiving platform is provided on the support platform.
[0010] The above-mentioned high-density tungsten alloy powder rod shaping device is characterized in that the number of guide sleeves and the number of vibrating blocks are both 10, the number of movable sleeves is one more than the number of guide sleeves, and the extra movable sleeve is located on the right side of the guide sleeve.
[0011] The above-mentioned high-density tungsten alloy powder rod shaping device is characterized in that the movable sleeve near the receiving platform is an open semi-cylindrical structure.
[0012] This utility model has the following advantages compared with the prior art:
[0013] 1. This utility model, by setting an ejector component, facilitates the lifting of the billet containing high-density tungsten alloy powder to a certain height after the initial shaping, allowing for a second shaping and improving the shaping effect. By setting a displacement component, in conjunction with the ejector component, the lifted billet containing high-density tungsten alloy powder enters the next guide sleeve for further shaping, thus achieving the desired shaping effect. It also enables the billet containing high-density tungsten alloy powder to automatically move to the left, completing the shaping and removing it from the shaping device. This achieves automated shaping, enabling assembly line operation, protecting worker health, reducing labor intensity, saving labor costs, significantly improving shaping efficiency, and achieving high-precision, high-efficiency powder compaction to ensure product consistency.
[0014] 2. This utility model uses a vibrating block to collide with a rod blank containing high-density tungsten alloy powder during its free fall under gravity. Under the action of inertial force, the high-density tungsten alloy powder inside the rod blank is shaped and positioned. A guide sleeve is used to limit the free fall of the rod blank containing high-density tungsten alloy powder, ensuring that it accurately lands on the vibrating block for shaped positioning.
[0015] 3. This utility model uses a horizontal cylinder to make the moving sleeve reciprocate by moving one guide sleeve position to the left and one guide sleeve position to the right. This moves the billet containing high-density tungsten alloy powder to the next guide sleeve for mounting and shaping. This process is repeated to gradually move the billet containing high-density tungsten alloy powder to the left, thereby completing the mounting and shaping and removing it from the mounting and shaping device.
[0016] 4. This utility model uses a vertical cylinder to drive a lifting platform to move vertically up and down, which in turn drives a push rod to move up and down. This allows the billet containing high-density tungsten alloy powder, which is on the vibrating block after the pier is shaped, to be pushed out of the current guide sleeve and into the moving sleeve. This facilitates the movement of the billet to the next guide sleeve in conjunction with the displacement component, or allows it to continue free-falling in the current guide sleeve. According to the requirements of pier shaping, the billet containing high-density tungsten alloy powder can undergo multiple free-falling movements in one guide sleeve before moving to the next guide sleeve, thereby controlling the packing density of the high-density tungsten alloy powder in the billet.
[0017] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] like Figure 1 and Figure 2 As shown, the high-density tungsten alloy powder rod pier shaping device of this utility model includes a pier shaping base 1, a support platform 2 above the pier shaping base 1, multiple vibrating blocks 3 arranged in a straight line on the support platform 2, an ejection assembly that cooperates with the vibrating blocks 3 on the support platform 2, an upright bracket 4 on the support platform 2, a guide platform 5 installed on the upright bracket 4, multiple guide sleeves 6 corresponding to the vibrating blocks 3 at the lower part of the guide platform 5, guide holes opened at the corresponding positions of the guide sleeves 6 on the guide platform 5, and a displacement assembly on the support platform 2. The displacement assembly includes a displacement bracket 7 installed on the support platform 2, a horizontal cylinder 8 on the displacement bracket 7, the output shaft of the horizontal cylinder 8 connected to a sliding platform 9, a movable sleeve 10 corresponding to the multiple guide sleeves 6 at the lower part of the sliding platform 9, and a through hole opened at the corresponding position of the movable sleeve 10 on the sliding platform 9.
[0027] It should be noted that the installation of the pier shaping base 1 and support platform 2 facilitates the installation of other components and provides space for the movement of the ejector assembly. The high-density tungsten alloy powder-filled billet collides with the vibrating block 3 during its free fall under gravity. Under the influence of inertia, the high-density tungsten alloy powder inside the billet is shaped into a pier. The installation of the upright bracket 4 and guide platform 5 facilitates the installation of the guide sleeve 6, thereby limiting the free fall of the billet containing the high-density tungsten alloy powder and ensuring its accurate landing on the vibrating block 3 for pier shaping. The ejector assembly facilitates the removal of the high-density tungsten alloy powder-filled billet after pier shaping. The billet is lifted to a certain height and then reshaped at the pier position to improve the shaping effect. By setting a displacement component and an ejection component to cooperate, the lifted billet containing high-density tungsten alloy powder enters the next guide sleeve 6 to continue shaping at the pier position, thereby improving the shaping effect. It also realizes that the billet containing high-density tungsten alloy powder automatically moves to the left, thus completing the shaping at the pier position and removing it from the shaping device. This realizes automated shaping at the pier position, achieving assembly line operation, protecting the health of workers, reducing the labor intensity of workers, saving labor costs, and greatly improving the efficiency of shaping at the pier position. It also achieves high-precision and high-efficiency powder compaction to ensure product consistency.
[0028] It should be noted that by setting multiple vibrating blocks 3 arranged in a straight line and setting corresponding guide sleeves 6, the rod blank containing high specific gravity tungsten alloy powder is supported by vibrating blocks 3 when it is in free fall in each guide sleeve 6.
[0029] It should be noted that the displacement bracket 7 facilitates the installation of the sliding platform 9 and the horizontal cylinder 8. The horizontal cylinder 8 causes the moving sleeve 10 to reciprocate by moving one guide sleeve 6 position to the left and one guide sleeve 6 position to the right. When the billet containing high-density tungsten alloy powder is ejected, the moving sleeve 10 moves one guide sleeve 6 position to the left, moving the billet to the next guide sleeve 6 for pier shaping. Then, the moving sleeve 10 moves one guide sleeve 6 position to the right to reset. When the billet containing high-density tungsten alloy powder is ejected again, the moving sleeve 10 moves one guide sleeve 6 position to the left, thus repeating the process to gradually move the billet containing high-density tungsten alloy powder to the left, thereby completing the pier shaping and removing it from the pier shaping device.
[0030] It should be noted that, according to the requirements of the pier shaping, the billet containing high-density tungsten alloy powder undergoes multiple free-fall motions in a guide sleeve 6 before moving to the next guide sleeve 6, in order to control the packing density of the high-density tungsten alloy powder in the billet.
[0031] like Figure 1 and Figure 2As shown, in this embodiment, the ejection assembly includes a vertical cylinder 11 mounted on a support platform 2. A lifting platform 12 is fixed to the end of the output shaft of the vertical cylinder 11. The lifting platform 12 is equipped with push rods 13 that cooperate with multiple vibrating blocks 3. By setting the vertical cylinder 11 to drive the lifting platform 12 to move vertically up and down, the push rods 13 move up and down, thus ejecting the high-density tungsten alloy powder-filled billet from the vibrating block 3 after the pier has been shaped, out of the current guide sleeve 6 and into the moving sleeve 10. This facilitates movement to the next guide sleeve 6 in conjunction with the displacement assembly, or allows the billet to continue its free-fall motion within the current guide sleeve 6.
[0032] like Figure 1 and Figure 2 As shown in this embodiment, two sliding rods 14 are also provided between the lifting platform 12 and the support platform 2. By setting the sliding rods 14 to limit the up and down movement of the lifting platform 12, the stable rise or fall of the lifting platform 12 is ensured.
[0033] like Figure 1 and Figure 2 As shown in this embodiment, a receiving platform 15 is provided on the support platform 2. By setting up the receiving platform 15, the billet containing high-density tungsten alloy powder after multiple stacking and shaping processes is stored, thereby improving work efficiency.
[0034] like Figure 1 and Figure 2 As shown, in this embodiment, there are 10 guide sleeves 6 and 10 vibrating blocks 3. The number of movable sleeves 10 is one more than the number of guide sleeves 6, and the extra movable sleeve 10 is located to the right of the guide sleeve 6. By controlling the number of guide sleeves 6 and the number of vibrating blocks 3, multiple billets containing high-density tungsten alloy powder are stacked and shaped. By making the number of movable sleeves 10 one more than the number of guide sleeves 6, and the extra movable sleeve 10 located to the right of the guide sleeve 6, it is convenient for multiple billets containing high-density tungsten alloy powder to be stacked and shaped sequentially in the movable sleeves 10.
[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the movable sleeve 10 near the receiving platform 15 is an open semi-cylindrical structure. By making the movable sleeve 10 near the receiving platform 15 an open semi-cylindrical structure, it is convenient to move the billet containing high-density tungsten alloy powder after the final pressing and shaping to the receiving platform 15 for receiving.
[0036] In actual use, guide sleeves 6 are named from right to left as guide sleeve #1, guide sleeve #2, guide sleeve #3, ..., guide sleeve #10, and movable sleeves 10 are named from right to left as movable sleeve #1, movable sleeve #2, movable sleeve #3, ..., movable sleeve #11, with guide sleeve #1 and movable sleeve #2 corresponding in position. A billet containing high-density tungsten alloy powder (#1) is placed into movable sleeve #2 and subjected to free fall to collide with vibrating block 3 for pier positioning. The billet is then ejected using an ejection assembly. This pier positioning process is repeated multiple times within the limit position of guide sleeve #1. Finally, the ejection assembly... The process involves ejecting billet #1, containing high-density tungsten alloy powder, into movable sleeve #2, and placing billet #2, also containing high-density tungsten alloy powder, into movable sleeve #1. Simultaneously, a displacement assembly aligns movable sleeve #1 with guide sleeve #1. Billet #1, containing high-density tungsten alloy powder, undergoes free fall under the constraint of guide sleeve #2, colliding with vibrating block #3 for pier positioning. Similarly, billet #2, containing high-density tungsten alloy powder, undergoes free fall under the constraint of guide sleeve #1, colliding with vibrating block #3 for pier positioning. This process is repeated to achieve automated pier positioning, enabling assembly line operation. The process is simple to operate and easy to promote and apply.
[0037] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
