Description

Technical Field

[0001] This utility model relates to the field of metal semi-solid pulping technology, specifically a pulping device based on metal semi-solid pulping and stirring quenching rod cooling technology. Background Technology

[0002] Semi-solid metal forming refers to a metal forming method that utilizes the semi-solid region during the two-phase transformation of metal from solid to liquid or from liquid to solid. It is a metal forming method with good rheological properties.

[0003] For example, Chinese Patent CN118989273B discloses a metal semi-solid pulping and cooling device and pulping equipment, including a rotating mechanism, two or more stirring mechanisms, a ladle, a cooling mechanism, a heat dissipation mechanism, and a controller. The technical solution of this application uses a solid structure for the stirring and quenching rod and employs a molten low-temperature metal alloy as the heat transfer medium for the stirring and quenching rod that needs cooling. Utilizing the high thermal conductivity and high boiling point of the low-temperature metal alloy, the stirring and quenching rod is quickly and reliably reduced to its initial temperature. The stirring and quenching rod has a lower initial temperature, resulting in better heat transfer to the high-temperature molten metal, which helps improve pulping quality, shorten pulping time, and increase production capacity. Compared to existing technologies, the heat dissipation mechanism and rotating mechanism for the coolant are separately configured, which does not affect the lifespan of the rotating mechanism, and even if the circulating pump malfunctions, it is less likely to be affected by temperature-related factors causing boiling over or cracking of the stirring rod.

[0004] However, the aforementioned metal semi-solid slurry cooling device and slurry equipment cannot cover the insulation tank after cooling the molten metal to a semi-solid state for heat preservation. In the open state of the insulation tank, the molten metal inside will undergo convective heat exchange with the air through the surface, resulting in rapid heat loss. Temperature fluctuations will cause the primary solid phase particles to coarsen, agglomerate, or the liquid phase components to segregate, which will destroy the uniformity of the semi-solid structure and affect the forming accuracy and mechanical properties of subsequent processing. Utility Model Content

[0005] The purpose of this invention is to provide a pulping device based on metal semi-solid pulping and stirring quenching rod cooling technology, in order to solve the problem mentioned in the background art that after the metal liquid is cooled to a semi-solid state, the heat preservation tank cannot be covered for heat preservation treatment, and the heat preservation tank in the open state will cause the internal metal liquid to undergo convection heat exchange with the air through the surface, resulting in rapid heat loss.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pulping device based on metal semi-solid pulping and stirring quenching rod cooling technology includes: an electric push rod, a V-shaped frame fixedly installed on the upper surface of the piston rod of the electric push rod, quenching rods fixedly installed at both ends of the lower surface of the V-shaped frame, a placement plate fixedly installed on the outer surface of the electric push rod, a U-shaped ring fixedly installed at both ends of the upper surface of the placement plate, the U-shaped rings being perpendicular to the quenching rods, and a heat preservation barrel being placed inside the U-shaped rings, so that the quenching rods can be pulled down and extended into the heat preservation barrel by the electric push rod; and a heat preservation mechanism rotatably installed at both ends of the lower surface of the V-shaped frame.

[0008] Preferably, the insulation mechanism can be pulled up to cover the upper end of the insulation bucket as the V-shaped frame rises, and can also be pulled up to unfold at the upper end of the insulation bucket as the V-shaped frame descends.

[0009] Preferably, two sets of ball bearings are rotatably mounted at both ends of the electric push rod, and an H-shaped positioning plate is slidably mounted between the two sets of ball bearings. The upper surface of the H-shaped positioning plate is fixedly mounted on the lower surface of the V-shaped frame.

[0010] Preferably, the heat preservation mechanism includes a connecting plate, which is fixedly installed at one end of a U-shaped ring. Two sets of connecting strips are rotatably installed on the upper surface of the connecting plate, and a heat preservation cover is fixedly installed at the other end of the connecting strips.

[0011] Preferably, the upper surface of the connecting strip has a sliding opening, a connecting arm is slidably installed in the sliding opening, a traction rod is rotatably installed on the upper surface of the connecting arm, the other end of the traction rod is rotatably installed in the Y-shaped frame, and the Y-shaped frame is fixedly installed at both ends of the lower surface of the V-shaped frame.

[0012] Preferably, the two sets of Y-shaped frames can pull the connecting arms to slide within the sliding bar opening along with the lifting and lowering of the V-shaped frames, thereby allowing the two sets of connecting bars to push the insulation cover to open and close.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of an electric push rod, placement plate, V-shaped frame, chilling rod, U-shaped ring, and insulation mechanism, when the molten metal is cooled to a semi-solid state, the insulation container containing the molten metal can be placed inside the U-shaped ring fixedly installed on the upper surface of the placement plate. The U-shaped ring guides the placement of the insulation container, ensuring it is precisely perpendicular to the chilling rod. Then, the electric push rod is activated, pulling down the V-shaped frame via the piston rod. As the V-shaped frame is pulled down, it simultaneously causes the H-shaped positioning plate fixedly installed on the lower surface to slide between two sets of ball bearings, thus providing vertical sliding for the V-shaped frame's lifting and lowering. During the descent of the V-shaped frame, it also pulls the insulation mechanism to slide synchronously to both ends, allowing the V-shaped frame to... The frame extends the chiller rod, which is fixedly installed on the lower surface, into the insulation tank to form a semi-solid slurry from the high-temperature molten metal. After the slurry is prepared, the electric push rod can be activated again to push the V-shaped frame and pull the chiller rod on the lower surface out of the insulation tank. During this process, the V-shaped frame will pull the insulation mechanism inward and close synchronously, thereby achieving a cover insulation treatment for the insulation tank. This cover insulation operation can reduce heat loss and maintain the state of the semi-solid molten metal, which is beneficial to subsequent processing operations. At the same time, the cover insulation of the insulation tank can also reduce the coarsening of the initial solid phase particles or the segregation of liquid metal components caused by local temperature unevenness, ensuring the uniformity of the microstructure of the semi-solid slurry, thereby improving the mechanical properties of the subsequently formed parts.

[0015] 2. Through the design of connecting plate, connecting strip, insulation cover, connecting arm, traction rod and Y-shaped frame, when the electric push rod pulls the V-shaped frame down, the Y-shaped frame fixed at both ends of its lower surface moves down synchronously. The Y-shaped frame can drive the traction rods that are rotatably installed at both ends to move down together. The lower end of the traction rod is rotatably installed on the upper surface of the connecting arm, and the lower surface of the connecting arm is slidably installed in the sliding strip opening of the connecting strip. This allows the moving traction rod to push the connecting arm to slide in the sliding strip opening. The sliding strip opening that is pushed can then drive the insulation cover to be pushed open to both ends on the upper surface of the connecting plate through the connecting strip. During this process, the V-shaped frame will continuously drive the cooling rod down and extend into the insulation barrel.

[0016] When pulping is completed, the electric pusher pushes the V-shaped frame to rise, which in turn drives the traction rod to move upward. The traction rod then pulls the connecting arm inward within the sliding strip opening, allowing the connecting rod to drive the insulation cover to close towards the center. During this process, the V-shaped frame continuously drives the quenching rod to rise and pull it out of the insulation barrel. The V-shaped frame can then be continuously pulled upward until both sets of insulation covers are completely closed and the insulation barrel is covered, at which point the process stops. Throughout the process, the reciprocating sliding of the connecting arm within the sliding strip opening and the lifting and lowering movement of the V-shaped frame are linked. Through the mechanical transmission characteristics of the linkage mechanism, the opening and closing of the insulation cover and the insertion and removal of the quenching rod are ensured to be synchronized. Furthermore, the insulation covers on both sides achieve uniform speed movement through the symmetrical Y-shaped frame and traction rod structure, avoiding skew and jamming. At the same time, the limiting of the sliding strip opening and the rotation fulcrum of the connecting plate ensure the accuracy of the cover installation, so that the edge of the insulation cover is aligned with the barrel opening and the sealing surface is tightly fitted when the insulation cover is closed.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2As shown, this embodiment provides a pulping device based on metal semi-solid pulping and stirring quenching rod cooling technology, including: an electric push rod 1, a V-shaped frame 102 fixedly installed on the upper surface of the piston rod of the electric push rod 1, quenching rods 103 fixedly installed at both ends of the lower surface of the V-shaped frame 102, a placement plate 101 fixedly installed on the outer surface of the electric push rod 1, a U-shaped ring 105 fixedly installed at both ends of the upper surface of the placement plate 101, the U-shaped ring 105 being perpendicular to the quenching rods 103, and a heat preservation barrel being placed inside the U-shaped ring 105, so that the quenching rods 103 can be pulled down and extended into the heat preservation barrel by the electric push rod 1, and a heat preservation mechanism 2 rotatably installed at both ends of the lower surface of the V-shaped frame 102.

[0023] The insulation mechanism 2 can be pulled up to cover the upper end of the insulation barrel as the V-shaped frame 102 rises, and it can also be pulled up to unfold at the upper end of the insulation barrel as the V-shaped frame 102 descends. Two sets of ball bearings 106 are rotatably installed at both ends of the electric push rod 1, and an H-shaped positioning plate 104 is slidably installed between the two sets of ball bearings 106. The upper surface of the H-shaped positioning plate 104 is fixedly installed on the lower surface of the V-shaped frame 102.

[0024] Through the design of the electric push rod 1, placement plate 101, V-shaped frame 102, cooling rod 103, U-shaped ring 105, and heat preservation mechanism 2, when the molten metal is cooled to a semi-solid state, the heat preservation container containing the molten metal can be placed inside the U-shaped ring 105 fixedly installed on the upper surface of the placement plate 101. The guiding effect of the U-shaped ring 105 ensures that the placed heat preservation container is precisely perpendicular to the cooling rod 103. Then, the electric push rod 1 can be activated to pull down the V-shaped frame 102 via the piston rod. During the downward movement of the V-shaped frame 102, the H-shaped positioning plate 104 fixedly installed on the lower surface slides down between two sets of ball bearings 106, thus providing vertical sliding for the lifting and lowering of the V-shaped frame 102. As the V-shaped frame 102 is pulled down, it simultaneously pulls the heat preservation mechanism 2 upwards. The two ends slide open, allowing the V-shaped frame 102 to drive the cooling rod 103 fixedly installed on the lower surface to extend into the insulation tank, turning the high-temperature molten metal into a semi-solid slurry. After the slurry is made, the electric push rod 1 can be activated again to push the V-shaped frame 102 to pull the cooling rod 103 on the lower surface out of the insulation tank. During this process, the V-shaped frame 102 will pull the insulation mechanism 2 to slide inward and close simultaneously, thereby achieving the insulation treatment of the insulation tank by covering it. This covering insulation operation can reduce heat loss and maintain the state of the semi-solid molten metal, which is beneficial to subsequent processing operations. At the same time, the covering insulation of the insulation tank can also reduce the coarsening of the primary solid particles or the segregation of liquid metal components caused by local temperature unevenness, ensuring the uniformity of the microstructure of the semi-solid slurry, thereby improving the mechanical properties of the subsequently formed parts.

[0025] like Figure 3As shown, the insulation mechanism 2 includes a connecting plate 201, which is fixedly installed at one end of a U-shaped ring 105. Two sets of connecting strips 202 are rotatably mounted on the upper surface of the connecting plate 201, and an insulation cover 203 is fixedly installed at the other end of the connecting strips 202. A sliding slot 204 is provided on the upper surface of the connecting strip 202, and a connecting arm 205 is rotatably mounted inside the sliding slot 204. A traction rod 206 is rotatably mounted on the upper surface of the connecting arm 205, and the other end of the traction rod 206 is rotatably mounted inside a Y-shaped frame 207. The Y-shaped frame 207 is fixedly installed at both ends of the lower surface of the V-shaped frame 102. The two sets of Y-shaped frames 207 can pull the connecting arm 205 to slide within the sliding slot 204 as the V-shaped frame 102 rises and falls, thereby allowing the two sets of connecting strips 202 to push the insulation cover 203 to open and close.

[0026] Through the design of the connecting plate 201, connecting strip 202, insulation cover 203, connecting arm 205, traction rod 206 and Y-shaped frame 207, when the electric push rod 1 pulls the V-shaped frame 102 down, the Y-shaped frame 207 fixed at both ends of its lower surface moves down synchronously. The Y-shaped frame 207 can drive the traction rod 206, which is rotatably installed at both ends, to move down together. The lower end of the traction rod 206 is rotatably installed on the upper surface of the connecting arm 205, and the lower surface of the connecting arm 205 is slidably installed in the sliding bar opening 204 of the connecting strip 202. This allows the downward-moving traction rod 206 to push the connecting arm 205 to slide in the sliding bar opening 204. The pushed sliding bar opening 204 can then drive the insulation cover 203 to be pushed open to both ends on the upper surface of the connecting plate 201 through the connecting strip 202. During this process, the V-shaped frame 102 will continuously drive the cooling rod 103 down and extend into the insulation barrel.

[0027] When pulping is complete, the electric pusher 1 pushes the V-shaped frame 102 upward, and the Y-shaped frame 207 drives the traction rod 206 upward. The traction rod 206 then pulls the connecting arm 205 inward within the sliding strip opening 204, allowing the connecting strip 202 to drive the insulation cover 203 to close towards the center. During this process, the V-shaped frame 102 continuously drives the quenching rod 103 upward and pulls it out of the insulation tank. The V-shaped frame 102 is then continuously pulled upward until both sets of insulation covers 203 are completely closed and the insulation tank lid is installed, at which point the process stops. Throughout the entire process, the connecting rod 202 continues to move upward. The reciprocating sliding of the connecting arm 205 within the sliding strip opening 204 is linked with the lifting and lowering motion of the V-shaped frame 102. Through the mechanical transmission characteristics of the linkage mechanism, the opening and closing of the insulation cover 203 and the insertion and removal of the cooling rod 103 are ensured to be synchronized. Furthermore, the insulation covers 203 on both sides achieve uniform speed movement through the symmetrical Y-shaped frame 207 and traction rod 206 structure, avoiding skewness and jamming. At the same time, the limiting position of the sliding strip opening 204 and the rotation fulcrum of the connecting plate 201 are used to ensure the accuracy of the cover installation, so that when the insulation cover 203 is closed, the edge is aligned with the barrel opening and the sealing surface is tightly fitted.

[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: When the molten metal is cooled to a semi-solid state, the insulated container containing the molten metal can be placed inside the U-shaped ring 105 fixedly installed on the upper surface of the placement plate 101. Through the guiding effect of the U-shaped ring 105, the placed insulated container can be precisely perpendicular to the cooling rod 103. Then, the electric push rod 1 can be activated to pull down the V-shaped frame 102 through the piston rod. When the V-shaped frame 102 descends, the Y-shaped frame 207 fixed at both ends of its lower surface moves down synchronously. The Y-shaped frame 207 can drive the traction rod 206, which is rotatably installed at both ends, to move down together. The lower end of the traction rod 206 is rotatably installed on the upper surface of the connecting arm 205, and the lower surface of the connecting arm 205 is slidably installed in the sliding groove opening 204 of the connecting bar 202. Thus, the moving traction rod 206 can push the connecting arm 205 to slide in the sliding groove opening 204. The sliding groove opening 204, which is pushed, can pass through the connecting bar. 202 drives the insulation cover 203 to be pushed open to both ends on the upper surface of the connecting plate 201. During this process, the V-shaped frame 102 continuously drives the cooling rod 103 to descend and extend into the insulation tank to form a semi-solid slurry from the high-temperature molten metal. When the slurry preparation is completed, the electric push rod 1 pushes the V-shaped frame 102 to rise, and the Y-shaped frame 207 can drive the traction rod 206 to move upward. The traction rod 206 can then pull the connecting arm 205 to slide inward within the sliding strip opening 204, thereby allowing the connecting strip to... 202 drives the insulation cover 203 to close towards the center. During this process, the V-shaped frame 102 continuously drives the cooling rod 103 to rise and pull it out of the insulation barrel. Then, the V-shaped frame 102 can be continuously pulled up until the two sets of insulation covers 203 are completely closed and the insulation barrel is covered, and then it stops. This realizes the automatic covering and insulation treatment of the insulation barrel. This covering and insulation operation can reduce heat loss and maintain the semi-solid molten metal state, which is beneficial to subsequent processing operations.

[0029] In summary, this pulping equipment can automatically cover the insulated tank after cooling the molten metal in the tank to a semi-solid state. This covering insulation operation can reduce heat loss and maintain the semi-solid state of the molten metal, which is beneficial for subsequent processing operations.
