Description

Technical Field

[0001] This utility model relates to the field of metal forming technology, specifically a metal powder forming device. Background Technology

[0002] Powder metallurgy is an industrial technology that produces metal materials, composite materials, and various types of products by taking metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, and then forming and sintering them. The basic process of powder metallurgy is to form the powder into a blank of the required shape. The purpose of forming is to obtain a compact of a certain shape and size, and to give it a certain density and strength.

[0003] A search revealed a patent document with publication number CN222242644 U, which discloses a metal powder forming device that can remove the shaped metal powder after it has been pressed into shape from the fixed base and take it out completely without damage. This is convenient and quick, and also protects the shaped object.

[0004] However, the above technical solutions have certain shortcomings. When the metal powder is poured into the mold cavity, dust will be generated and will drift arbitrarily with the airflow, resulting in the loss of some metal powder. In addition, the demolding component is located on the front side of the mold cavity, which occupies space and reduces the aesthetics. Therefore, a metal powder forming device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a metal powder forming device to solve the technical problems mentioned in the background.

[0007] The mold cavity assembly includes a base plate that is slidably disposed in a receiving groove. The front and rear end faces of the base plate are fitted with a front plate, and the left and right end faces of the base plate are connected with side plates. Each set of side plates has a slot on its outer wall near the top. The left and right outer walls of the base are reserved with frame grooves. A collection frame for collecting metal powder is installed in the frame grooves. The upper inner wall of the frame grooves has an exhaust channel corresponding to the slot.

[0008] As a preferred technical solution, the base is equipped with an air pump, the input end of the air pump is provided with two sets of branch pipes that communicate with the inner wall of the frame groove, and the output end of the air pump is connected to an air inlet pipe extending to the outside of the base.

[0009] As a preferred technical solution, the front plate located on the rear surface is fixed to the top of the base plate, and the other set of front plates and the two sets of side plates are rotatably disposed on the end face of the base plate.

[0010] As a preferred technical solution, the lower inner wall of the receiving groove is equipped with two sets of hydraulic cylinders for driving the bottom plate to rise, and the inner wall of the receiving groove is fixed with a positioning frame for supporting the bottom of the bottom plate.

[0011] As a preferred technical solution, the top of the base is provided with a clearance groove at the edge of the receiving groove to allow the front plate and two sets of side plates to unfold.

[0012] As a preferred technical solution, the collection frame is equipped with a breathable mesh, and a notch is reserved at the bottom of the collection frame corresponding to the branch pipe.

[0013] As a preferred technical solution, the die head and the die cavity assembly are positioned relatively aligned and their dimensions are matched.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A metal powder forming apparatus, such as Figures 1 to 5 As shown, the system includes a base 100, which includes a pre-reserved receiving groove 150 at the top. A mold cavity assembly 200 is installed in the receiving groove 150. A pressing head 130 for pressing metal powder is provided above the base 100. An L plate 110 is fixed to the upper surface of the base 100 above the pressing head 130. An electric push rod 120 for driving the pressing head 130 to lower is installed on the top of the L plate 110.

[0027] The mold cavity assembly 200 includes a base plate 250 that is slidably disposed in the receiving groove 150. The front and rear end faces of the base plate 250 are fitted with a front plate 220. The left and right end faces of the base plate 250 are connected with side plates 230. The outer wall of each set of side plates 230 is provided with a slot 240 near the top. The left and right outer walls of the base 100 are reserved with frame grooves 101. A collection frame 180 for collecting metal powder is installed in the frame groove 101. The upper inner wall of the frame groove 101 is provided with an air extraction channel 160 corresponding to the slot 240.

[0028] The front plate 220 located on the rear surface is fixed to the top of the base plate 250, and the other set of front plates 220 and the two sets of side plates 230 are rotatably mounted on the end face of the base plate 250.

[0029] An air pump 190 is installed inside the base 100. The input end of the air pump 190 is provided with two sets of branch pipes 191 that are connected to the lower inner wall of the frame groove 101. The output end of the air pump 190 is connected to an air inlet pipe that extends to the outside of the base 100.

[0030] Metal powder is placed in the mold cavity formed by the front plate 220 and the side plate 230. At the same time, the air pump 190 will work synchronously, causing the dust in the mold cavity to flow towards the slot 240 and enter the collection frame 180 through the air extraction channel 160 to collect the metal powder that is raised. This prevents the dust from floating around and being inhaled by workers, which is harmful to their health. The metal powder can be collected and removed for use when a certain amount is accumulated, which can save the cost of using metal powder to a certain extent.

[0031] After the metal powder is poured into the mold cavity, the electric push rod 120 can be controlled to work, which will push the pressing head 130 to lower into the mold cavity to complete the pressing work. The pressing head 130 then returns to its original position, while the hydraulic cylinder 210 will push the bottom plate 250 upward, causing the mold cavity formed by the front plate 220 and the side plates 230 to rise synchronously. The front plate 220 and the two sets of side plates 230 can be manually rotated around the connection point of the bottom plate 250, as shown in the instruction manual. Figure 3 As shown, the front plate 220 and the side plate 230 will enter the relief groove 140. Using tools, the metal part located on the bottom plate 250 and which has been pressed and formed can be moved, thereby achieving the effect of quick demolding and material unloading.

[0032] Please refer to this carefully. Figure 2 The lower inner wall of the receiving groove 150 is equipped with two sets of hydraulic cylinders 210 for driving the bottom plate 250 to rise, and the inner wall of the receiving groove 150 is fixed with a positioning frame 170 for supporting the bottom of the bottom plate 250.

[0033] The extension end of the hydraulic cylinder 210 rises and exerts an upward lifting force on the base plate 250, causing the mold cavity formed by the front plate 220 and the side plate 230 to rise, thereby facilitating the manual removal of the pressed metal parts.

[0034] Please refer to this carefully. Figure 1 and Figure 2 The top of the base 100 is provided with a clearance groove 140 at the edge of the receiving groove 150 for the front plate 220 and the two sets of side plates 230 to unfold.

[0035] This allows the unfolded front plate 220 and the two sets of side plates 230 to be placed within the relief groove 140, so that the top of the base 100 and the surface of the bottom plate 250 form a horizontal plane, which can easily push the pressed metal part to one side and facilitate the unloading of the metal part.

[0036] Please refer to this carefully. Figure 5 The collection frame 180 is equipped with a breathable mesh 181, and a notch is reserved at the bottom of the collection frame 180 corresponding to the branch pipe 191.

[0037] The air-permeable mesh 181 is used to block and collect metal powder in the air. At the same time, the air passing through the air-permeable mesh 181 enters the branch pipe 191 through the gap and is finally discharged to the outside to complete the circulation.

[0038] Please refer to this carefully. Figure 1 The die head 130 and the mold cavity assembly 200 are aligned and their dimensions match.

[0039] When the die head 130 is pushed down by the electric push rod 120, it can enter the die cavity formed by the front plate 220 and the side plate 230 in the die cavity assembly 200, and finally complete the purpose of pressing metal powder.

[0040] When in use, the metal powder is placed in the mold cavity formed by the front plate 220 and the side plate 230. At the same time, the air pump 190 will work synchronously, causing the dust in the mold cavity to flow towards the slot 240 and enter the collection frame 180 through the air extraction channel 160 to collect the metal powder that is raised, so as to prevent it from floating around and being inhaled by workers and causing health hazards. The metal powder can be collected and taken out for use when a certain amount is accumulated, which can save the cost of using metal powder to a certain extent.

[0041] After the metal powder is poured into the mold cavity, the electric push rod 120 can be controlled to work, which will push the pressing head 130 to lower into the mold cavity to complete the pressing work. The pressing head 130 then returns to its original position, while the hydraulic cylinder 210 will push the bottom plate 250 upward, causing the mold cavity formed by the front plate 220 and the side plates 230 to rise synchronously. The front plate 220 and the two sets of side plates 230 can be manually rotated around the connection point of the bottom plate 250, as shown in the instruction manual. Figure 3 As shown, the front plate 220 and the side plate 230 will enter the relief groove 140. The metal part located on the bottom plate 250 and which has been pressed and formed can be moved by a tool, thereby achieving the effect of quick demolding and material unloading. The parts not involved in this device are the same as or can be implemented by existing technology.

[0042] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, but such modifications, substitutions, and variations are protected by patent law as long as they fall within the scope of the claims of the present invention.
