Description

Technical Field

[0001] This application relates to the technical field of precision manufacturing of alloy rods, and particularly to a dry-bag multi-hole loader for alloy rods at a decoration construction site. Background Art

[0002] A dry-bag press is a precision powder extrusion molding device. It places materials into the die holes of a mold and then performs extrusion molding after sealing with an elastic sealing cover plate. Since the requirements for the process control of cemented carbide round bars are very strict, it is necessary to ensure that their quality fully meets all product requirements needed by customers.

[0003] During the process of loading materials into a three-hole mold, a special shovel is used to fill each die hole one by one. However, this process is time-consuming and laborious. When the filling amount of each of the three die holes is 375 g, materials of the same weight need to be weighed each time and placed in the shovel for filling, and weighing continues after filling; or the die holes are filled flat to meet the filling within the error range. However, during the loading process, due to the influence of vibration, the die holes filled with materials initially are prone to cause the materials to overflow outside the mold, resulting in waste. The filling time required for any filling method is about 30 minutes. Repeated and cumbersome weighing and then adding materials in sequence affect the production efficiency. Making each die hole filled flat one by one leads to waste of materials, and the material data filled in each die hole is not accurate enough, thus affecting the accuracy of the process dimensions. Summary of the Utility Model

[0028] In order to make the objectives, technical solutions and advantages of the present disclosure clearer and more understandable, the present disclosure will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0029] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs.

[0030] To facilitate the understanding of the alloy rod dry bag multi-hole feeder provided by the embodiments of the present application, first, its application scenario will be described. The dry bag press is a precision powder extrusion forming device. It places the material into the die holes of a mold and then performs extrusion forming after sealing with an elastic sealing cover plate. Since the requirements for the process of cemented carbide round rods are very strict, it is necessary to ensure that their quality fully meets all product requirements needed by customers. Currently, during the process of loading materials into a three-hole mold, a special shovel is used to fill each die hole one by one. However, this process is time-consuming and laborious. When the filling amount in each of the three die holes is 375 g, it is necessary to weigh the same weight of materials each time and place them in the shovel for filling, and continue weighing after filling; or the die holes are filled flat to meet the filling within the error range. However, during the loading process, due to the influence of vibration, the die holes filled with materials initially are likely to cause the materials to overflow outside the mold, resulting in waste. The filling time required for any of these filling methods is about 30 minutes. The sequential addition of materials after multiple cumbersome weighings affects the production efficiency. Making each die hole filled flat one by one leads to waste of materials, and the material data filled in each die hole is not accurate enough, thus affecting the accuracy of the process dimensions. In view of this, the present application provides an alloy rod dry bag multi-hole feeder, which simplifies the material filling process, ensures the accuracy of the filled materials, avoids waste of materials, and at the same time speeds up the filling speed and improves the production efficiency.

[0031] Referring Figure 1 to Figure 2 as shown in and, the alloy rod dry bag multi-hole feeder provided by the embodiments of the present application includes a multi-hole feeder that cooperates with a multi-hole mold for equal filling of materials; in the present application, the previous method of sequentially adding materials to a single hole is changed, and a multi-hole feeder is used to simultaneously add the same amount of materials to multiple die holes 110 of the multi-hole mold. The feeding time is reduced from the previous 30 minutes to the current 5 minutes for filling, thus greatly improving the production efficiency and reducing waste of materials.

[0032] Moreover, the multi-hole feeder in the present application simplifies the filling process, and the filling amounts in multiple die holes 110 are accurate and reliable, meeting the accuracy of the process dimensions after pressing. Specifically, the multi-hole feeder includes: a ring 10 and a conical barrel 20 circumferentially connected to the bottom of the ring 10; the bottom of the ring 10 is circumferentially connected to the open end of the conical barrel 20. In the present application, it is formed into a whole by welding after being prefabricated separately or formed by integral casting of standard dimensions. To reduce the mold opening production cost, it is preferably formed by split welding. The bottom tapered end of the conical barrel 20 is welded and sealed with a fitting plate body 40, and after positioning and opening holes on the fitting plate body 40, multiple flow guiding columns 30 are welded and connected, thereby ensuring that the multiple flow guiding columns 30 communicate with the inner cavity of the conical barrel 20, and the conical barrel 20 can well guide the materials.

[0033] Combined Figure 3As shown in the figure, the porous feeder in this application is a vessel made of stainless steel. The material is durable and has a smooth flow surface, and it is not easy to deform or damage. In a specific embodiment of this application, the ring 10, the conical barrel 20, the fitting plate body 40, and the diversion column 30 are all prefabricated and processed with a 2-mm-thick stainless steel plate. The height of the ring 10 is 20 mm, and the outer diameter of the ring 10 is 153.3 mm. Then, the outer diameter of the top open end of the conical barrel 20 is also 153.3 mm. In order to better increase the diversion of materials, as Figure 3 shown in the figure, the vertical section of the conical barrel 20 is an isosceles trapezoid, indicating that the conical barrel 20 is a conical cylinder. It has a better inclination for diverting materials. The diameter of the upper base of the conical barrel 20 is larger than the diameter of the lower base of the conical barrel 20, and the angle between the upper base of the conical barrel 20 and the inclined plane is 60°. The upper part of the conical barrel 20 is open for easy loading of materials. The outer diameter of the lower tapered end of the conical barrel 20 is 95.6 mm, and the height of the conical barrel 20 is 50 mm. From this, it can be obtained that the height of the conical barrel 20 is 50 mm, the diameter of the upper base of the conical barrel 20 is 153.3 mm, the diameter of the lower base of the conical barrel 20 is 95.6 mm; the angle between the upper base of the conical barrel 20 and the inclined plane is 60°, and the angle between the inclined plane of the conical barrel 20 and the fitting plate body 40 is 120°, so as to have a better effect of diverting materials. Of course, in other embodiments of this application, according to the diversion of materials with different properties, the height, the diameter of the upper base, the inclined plane angle, and the diameter of the lower base of the conical barrel 20 can all be changed according to actual design requirements.

[0034] Refer to Figure 4 and Figure 5 shown in the figure, the bottom tapered end of the conical barrel 20 has a fitting plate body 40 that matches the top plane of the porous mold. Thus, the matching installation performance is higher. By using the fitting plate body 40 to match the top plane of the porous mold, the tightness between the two is higher. And the diameter of the fitting plate body 40 is smaller than the diameter of the top plane of the porous mold. It is easy to install and improves the stability after installation.

[0035] Exemplarily, the porous mold is a three-hole mold 100. The height of the three-hole mold 100 is 490 mm, the diameter of the three-hole mold 100 is 98 mm. The three-hole mold 100 is an overall cylindrical mold. The top plane of the three-hole mold 100 is 98 mm. The outer diameter of the bottom tapered end of the porous feeder is 95.6 mm. Under the blocking effect of the fitting plate body 40, the contact area is greatly guaranteed and the stability is enhanced.

[0036] The three die holes 110 of the three-hole die 100 are equally spaced. After filling 375 g of tungsten carbide powder into each die hole 110 and then pressing, in order to further increase the connection stability, three flow guiding columns 30 are equally spaced circumferentially along the fitting plate body 40 at the bottom tapered end of the tapered barrel 20. The three flow guiding columns 30 are in one-to-one correspondence and cooperation with the three die holes 110 of the three-hole die 100. The three flow guiding columns 30 are inserted into the three die holes 110 in a matching manner to realize the positioning of the multi-hole loader. It can be seen that the tops of the three flow guiding columns 30 are flush with or slightly lower than the upper surface of the fitting plate body 40. After positioning and opening holes, the three flow guiding columns 30 are welded at the opening positions. The bottoms of the three flow guiding columns 30 protrude outward from the fitting plate body 40, thereby ensuring stable flow guiding performance after being inserted into the die holes 110.

[0037] When the three flow guiding columns 30 are in one-to-one correspondence and cooperation with the three die holes 110 of the three-hole die 100, the center of the fitting plate body 40 coincides with the center of the top plane. The installation position is reasonable, and the uniform flow distribution effect is more significant. Moreover, each flow guiding column 30 is inserted into the corresponding die hole 110 by at least 20 mm. The insertion stability performance is higher. The diameter of each flow guiding column 30 is at least 3.5 mm smaller than the diameter of each die hole 110. This ensures a high degree of tight fit. Exemplarily, the diameter of each die hole 110 is 16.7 mm, and the outer diameter of each flow guiding column 30 is 13 mm. The difference in distance ensures the overall connection tightness.

[0038] In a specific embodiment of the present application, the total filling amount of the three die holes 110 of the three-hole die 100 is 1125 g. By pre-installing the multi-hole loader on the top of the three-hole die 100, the fitting plate body 40 and the top plane of the three-hole die 100 are closely fitted. Weigh 1125 g of tungsten carbide powder, and use a shovel to pour the total weight of tungsten carbide powder into the multi-hole loader. The ring 10 realizes the shielding function while enhancing the overall strength. The tungsten carbide powder flows into the three die holes 110 under the action of the tapered barrel 20. Through scraping and leveling, the total weight of the material is evenly filled in the three die holes 110, and the multi-hole filler is taken out after pressing. The whole loading process does not waste any material, ensuring the accuracy of filling. Subsequently, the three-hole die 100 is blocked with a cover plate for extrusion molding operation.

[0039] In the present application, after comprehensively weighing the materials required to be filled in multiple die holes 110, the materials are poured into the tapered barrel 20 and evenly flow into multiple die holes 110 by using the fluidity of the materials. Subsequently, scraping and compaction treatments are carried out. The materials do not cause any waste, the filling amounts of multiple die holes 110 are accurately controllable, the filling process is simplified, and the production efficiency is improved.
