Description

Technical Field

[0001] This application relates to the field of powder metallurgy forming technology, specifically to a powder metallurgy product forming and feeding device. Background Technology

[0002] Powder metallurgy is a process technology that involves producing metal powders or using metal powders as raw materials, followed by shaping and sintering to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology; therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Powder metallurgy pressing dies are used in powder metallurgy processes to press metal or non-metal powders into blanks of specific shapes and sizes. These dies typically consist of an upper die, a lower die, and a female die. During the pressing process, powder is filled into the die cavity, and pressure is applied to bind and densify the powder particles, forming a blank with a certain strength and shape. The blank is then removed from the die cavity using auxiliary tools.

[0003] For example, the patent with publication number CN220659219U discloses a powder metallurgy forming mold for flanges, which includes a body, multiple limit rods, a top plate, an upper mold, a lower mold, a mold cavity, a movable groove, a movable plate, and side blocks. This facilitates the demolding of the formed split flanges without the need for auxiliary tools to remove the formed split flanges from the mold cavity, thus improving the working efficiency of powder metallurgy for split flanges.

[0004] When using the aforementioned patented powder metallurgy forming mold, after pressing the material down and then lifting it up, some material remains on the bottom of the mold. If this residue is not cleaned, it will affect the quality of the finished product pressed with different materials in the next use of the mold. Traditional pressing molds cannot automatically clean the bottom, requiring manual wiping by workers, which is quite cumbersome. Therefore, a powder metallurgy product forming and unloading device needs to be designed to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0017] like Figures 1-3 As shown, this application provides a powder metallurgy product forming and feeding device, including a workbench 1, a pressing component 2 installed on the workbench 1, the pressing component 2 being used to press and form metallurgical powder, the pressing component 2 including a bracket 201 fixedly installed on the workbench 1, a hydraulic cylinder 202 fixedly installed on the bracket 201, the output end of the hydraulic cylinder 202 passing through the bracket 201. An upper mold 203 is fixedly installed at the output end of the hydraulic cylinder 202. At the same time, a lower mold 204 is fixedly installed on the worktable 1 along the same vertical line as the upper mold 203. A mold cavity 205 is opened on the lower mold 204. A through hole (not shown in the figure) that matches the size of the mold cavity 205 is opened on the worktable 1. The upper mold 203 is adapted to move linearly with the output end of the hydraulic cylinder 202 so as to press the metallurgical powder in the mold cavity 205 into shape. The workbench 1 has a support rod (not shown in the figure), and a material picking component 3 is installed on the support rod. The material picking component 3 is used to pick up the blank formed by pressing metallurgical powder in the mold cavity 205. The material picking component 3 includes a base plate 301 fixedly installed on the support rod, a first motor 302 fixedly installed on the base plate 301, and a cam 303 fixedly installed at the output end of the first motor 302. A limiting plate 304 is fixedly installed on the workbench 1. A push rod 305 is movably inserted through the limiting plate 304. The push rod 305 has a connecting end. The push rod 305 contacts the cam 303 through the connecting end. A spring 306 is sleeved on the push rod 305. One end of the spring 306 is connected to the connecting end, and the other end of the spring 306 is connected to the limiting plate 304. A top block 307 is fixedly installed at one end of the push rod 305. The top block 307 is located in the through hole to support the metallurgical powder stored in the mold cavity 205. The cam 303 is adapted to rotate with the output end of the first motor 302 to push the connecting end compression spring 306, and then push the top block 307 to take out the blank pressed in the mold cavity 205. A cleaning component 4 is installed on the support 201. The cleaning component 4 is used to remove the powder remaining after the upper mold 203 and the lower mold 204 come into contact. The cleaning component 4 includes a concave plate 401 fixedly installed on the support 201. A second motor 402 is fixedly installed on one side of the concave plate 401. A bidirectional lead screw 403 is fixedly installed at the output end of the second motor 402. One end of the bidirectional lead screw 403 is connected to a bearing on one side of the inner wall of the concave plate 401. Two sets of screw sleeves 404 are threadedly connected to the bidirectional screw 403. Two sets of vertical rods 405 are provided between the inner walls of the concave plate 401. The screw sleeve 404 is movably sleeved on the two sets of vertical rods 405 to restrict the movement of the screw sleeve 404. A cleaning brush 406 is fixedly installed on the screw sleeve 404. The bidirectional lead screw 403 is adapted to rotate with the output end of the second motor 402, so that the two sets of lead screw sleeves 404 move along the straight direction of the bidirectional lead screw 403 and move closer or further away from each other, so as to remove the powder remaining after the upper mold 203 and the lower mold 204 come into contact. Working principle: Powder metallurgy powder is loaded into the mold cavity 205. The hydraulic cylinder 202 is started to drive the upper mold 203 downward to extrude the metallurgical powder in the mold cavity 205 and form a blank. Then the hydraulic cylinder 202 is reset and the upper mold 203 is moved upward. Then the first motor 302 is started to make the cam 303 rotate and drive the connecting end to move upward, so that the height position of the top block 307 on the push rod 305 changes and the spring 306 is compressed. At the same time, the top block 307 pushes the formed blank out of the mold cavity 205, which facilitates the demolding of the formed blank. It is not necessary to use auxiliary tools to remove the formed split flange in the mold cavity 205. When the hydraulic cylinder 202 resets and adjusts the upper mold 203 to move upward, the second motor 402 is then started to drive the bidirectional lead screw 403 to rotate, so that the two sets of lead screw sleeves 404 move along the straight direction of the bidirectional lead screw 403 and move closer or further away from each other, so as to remove the powder remaining after the upper mold 203 and the lower mold 204 come into contact.
