Description

Technical Field

[0001] This utility model relates to the field of magnesium-aluminum alloy production and processing technology, and in particular to a rapid cooling mechanism for magnesium-aluminum alloy production and processing. Background Technology

[0002] Magnesium-aluminum alloys are a type of alloy. The low density of magnesium and aluminum alloys improves their specific properties, resulting in excellent strength, rigidity, and dimensional stability.

[0003] After magnesium-aluminum alloy is shaped into a blank in a high-temperature molten state, the overall temperature of the magnesium-aluminum alloy is relatively high. In order to reduce the temperature of the magnesium-aluminum alloy, it is cooled by natural cooling or spraying coolant. When natural ventilation is used, the magnesium-aluminum alloy needs to be laid out, which makes it very easy for the magnesium-aluminum alloy to be impacted during the laying process, and also prolongs the cooling time. Spraying coolant limits the contact between the coolant and the magnesium-aluminum alloy, which means that the magnesium-aluminum alloy needs to consume a lot of time for cooling operations, making it impossible to quickly carry out subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem of long cooling time for magnesium-aluminum alloys in the prior art, and to propose a rapid cooling mechanism for the production and processing of magnesium-aluminum alloys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid cooling mechanism for magnesium-aluminum alloy production and processing includes a housing for cooling the magnesium-aluminum alloy. The housing is fixedly mounted with a bracket, a partition, a valve, and a cooler. The housing is divided into a cooling chamber and a filtering chamber by the partition. An input pipe and an output pipe for supplying coolant are connected between the cooling chamber and the filtering chamber. A filtering assembly for filtering the coolant is installed inside the filtering chamber. A hydraulic cylinder is fixedly mounted on the bracket, and a movable rod extending into the cooling chamber is fixedly connected to the output end of the hydraulic cylinder. A clamping structure for clamping the magnesium-aluminum alloy is installed on the movable rod.

[0007] Preferably, the cooling chamber and the filter chamber are horizontally opened from top to bottom, and one-way valves for controlling the flow direction of coolant are installed in the input pipe and the output pipe.

[0008] Preferably, the filter assembly includes a filter frame installed in the filter chamber, a frame connected to the filter frame by screws, and a filter cloth for filtering coolant on the frame. A limiting plate extending to the outside of the housing is fixedly installed on the filter frame, and a locking bolt connected to the housing is threaded on the limiting plate.

[0009] Preferably, the clamp structure includes a fixed cylinder and a support fixedly installed on the movable rod. The support has symmetrically arranged mounting plates placed inside, and the mounting plates are integrally connected with circumferentially distributed support plates for supporting the lower end of the magnesium-aluminum alloy. The fixed cylinder has symmetrically arranged mounting ends installed inside, and the mounting plates are integrally connected with circumferentially distributed pressing plates for pressing the upper end of the magnesium-aluminum alloy.

[0010] Preferably, the support plate and the pressing plate are plate-shaped structures, and the support plate and the pressing plate are provided with positioning holes for placing the magnesium-aluminum alloy. The positioning holes are of a shape and a circular structure that are compatible with the magnesium-aluminum alloy.

[0011] Preferably, the fixed cylinder and the support are arranged from top to bottom, the mounting plate is threaded with a fixing bolt connected to the support, the fixed cylinder is slidably fitted with symmetrically arranged movable plates, and the movable plates are fixedly installed with positioning rods extending into the mounting end, and the movable plates and the fixed cylinder are welded with evenly distributed springs.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model separates the cooling chamber and the filtering chamber by installing a partition inside the box, and keeps the temperature of the coolant at a low level by the flow of coolant, thereby enabling the magnesium-aluminum alloy inside the box to cool quickly, avoiding the time consumed by natural cooling or spray cooling.

[0014] 2. This utility model uses a pressing plate and a support plate to press the magnesium-aluminum alloy from both ends, which can ensure that the magnesium-aluminum alloy will not be subjected to excessive impact during the cooling process. Furthermore, by setting the pressing plate and the support plate circumferentially, multiple magnesium-aluminum alloys can be cooled simultaneously, further improving the cooling efficiency of magnesium-aluminum alloys.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A rapid cooling mechanism for the production and processing of magnesium-aluminum alloys includes a housing 1 for cooling the magnesium-aluminum alloys. The housing 1 is fixedly equipped with a bracket, a partition 2, a valve, and a cooler. The housing 1 is divided into a cooling chamber and a filtering chamber by the partition 2.

[0022] The cooling chamber and the filter chamber are connected by an inlet pipe 3 and an outlet pipe 4 for supplying coolant. The cooling chamber and the filter chamber are horizontally opened from top to bottom. One-way valves for controlling the flow direction of coolant are installed in the inlet pipe 3 and the outlet pipe 4. It should be noted that after the high-temperature magnesium-aluminum alloy enters the cooling chamber, the temperature of the coolant gradually rises. At the same time, it immediately sends a signal to the valve and the cooler. The warm coolant enters the filter chamber through the inlet pipe 3. The cooler cools the coolant flowing into the outlet pipe 4, so that the coolant can circulate and thus maintain the temperature of the coolant.

[0023] The filter chamber is equipped with a filter assembly for filtering the coolant.

[0024] The filter assembly includes a filter frame 5 installed within the filter chamber. A frame is screwed into the filter frame 5, and a filter cloth 6 for filtering the coolant is mounted on the frame. (See attached instruction manual.) Figure 2 As shown, unfiltered coolant flows into the bottom of the filter chamber, and only filtered coolant flows into the cooling chamber through the output pipe 4. The filter frame 5 and filter cloth 6 can intercept metal debris in the coolant. A limiting plate 7 extending outside the housing 1 is fixedly installed on the filter frame 5, and a locking bolt connected to the housing 1 is threaded on the limiting plate 7. By pulling out the limiting plate 7, the filter frame 5 can be pulled out as a whole, so that the operator can clean the filter frame 5.

[0025] A hydraulic cylinder 8 is fixedly installed on the bracket, and a movable rod extending into the cooling chamber is fixedly connected to the output end of the hydraulic cylinder 8. A clamping structure for clamping the magnesium-aluminum alloy is installed on the movable rod.

[0026] The clamp structure includes a fixed cylinder 9 and a support 10 fixedly installed on the movable rod. The support 10 has symmetrically arranged mounting plates 11, and the mounting plates 11 are integrally connected with circumferentially distributed support plates 12 for supporting the lower end of the magnesium-aluminum alloy. The fixed cylinder 9 has symmetrically arranged mounting ends 13, and the mounting plates 11 are integrally connected with circumferentially distributed pressing plates 14 for pressing the upper end of the magnesium-aluminum alloy.

[0027] According to the instruction manual Figure 3 As shown, the support plate 12 and the pressing plate 14 are plate-shaped structures, and the support plate 12 and the pressing plate 14 are provided with positioning holes for placing magnesium-aluminum alloy. The positioning holes are of the shape and circular structure that are adapted to magnesium-aluminum alloy. The shape of the positioning holes is limited according to the type of magnesium-aluminum alloy, so that the support plate 12 and the pressing plate 14 can limit the plate-shaped or cylindrical magnesium-aluminum alloy.

[0028] The fixed cylinder 9 and the support 10 are arranged from top to bottom. The mounting plate 11 is threaded with a fixing bolt connected to the support 10. The fixed cylinder 9 is slidably fitted with a symmetrically arranged movable plate 15, and a positioning rod 16 extending into the mounting end 13 is fixedly installed on the movable plate 15. Springs 17 are evenly distributed between the movable plate 15 and the fixed cylinder 9.

[0029] The pressing plate 14 can be assembled by the cooperation of the positioning rod 16 and the mounting end 13. By adjusting the position of the mounting end 13, the pressing plate 14 and the support plate 12 can clamp magnesium-aluminum alloys of different lengths. The circumferential arrangement of the support plate 12 and the pressing plate 14 can clamp multiple magnesium-aluminum alloys at the same time, which can prevent the magnesium-aluminum alloys from impacting each other during cooling. At the same time, the magnesium-aluminum alloys are fully immersed in the coolant, which can increase the contact between the coolant and the magnesium-aluminum alloys and further improve the cooling efficiency of the magnesium-aluminum alloys.

[0030] It should be noted that the specific models and specifications of the hydraulic cylinder 8, valves, coolers, and check valves need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] The support plate 12 and the pressing plate 14 are selected according to the specifications of the magnesium-aluminum alloy so that the positioning holes on the support plate 12 and the pressing plate 14 can correspond to each other for the plate-shaped or cylindrical magnesium-aluminum alloy.

[0033] The mounting plate 11 is connected to the support 10 by fixing bolts, and the lower end of the magnesium-aluminum alloy is extended into the positioning port to press the pressing plate 14. When the pressing plate 14 drives the mounting end 13 to slide in the fixing cylinder 9, the pressing plate 14 can press the magnesium-aluminum alloy from the top position when it moves down. Under the action of the spring 17, the positioning rod 16 extends into the mounting end 13.

[0034] The extension and retraction of the output end of hydraulic cylinder 8 drives the moving rod to move into the cooling chamber, where the magnesium-aluminum alloy can be cooled after contacting the coolant.

[0035] When the valve and the cooler are opened, the coolant in the cooling chamber is transported to the filter chamber through the inlet pipe 3 after the valve is energized. The filter frame 5 and the filter cloth 6 can intercept metal debris in the coolant. The filtered coolant flows to the outlet pipe 4, and the cooler performs a cooling operation on the coolant entering the outlet pipe 4, so that the cooled coolant flows into the cooling chamber, thereby cooling the magnesium-aluminum alloy entering the cooling chamber.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
