Description

Technical Field

[0001] The utility model relates to the technical field of metal processing cooling, in particular to a cooling device for aluminum profile forming. Background Art

[0002] Metal processing refers to the production activities of humans to process materials composed of metal elements or mainly composed of metal elements with metal characteristics. It is a process technology that processes metal materials into articles, parts, and components, including large parts such as bridges and ships, and even fine components such as engines, jewelry, and watches. It is widely used in different fields such as science, industry, art, and handicrafts.

[0003] As a kind of metal, the forming of aluminum mainly depends on an aluminum profile extruder. During the production process, an aluminum rod is placed on a fixed forming die for extrusion, and aluminum profiles of corresponding specifications can be obtained. When the aluminum profile is extruded from the outlet of the aluminum rod extruder, due to its high temperature, the hardness of the profile is insufficient. Generally, during the subsequent conveying process, it is shaped by cooling.

[0004] After the aluminum profile is extruded and formed, it is cooled by flushing with cooling water. The bent aluminum profile after being flushed with water is cut and then straightened by pulling at both ends. In the actual application process of this cooling method, the aluminum profile will be deformed due to the impact force generated by the water flushing, increasing the subsequent straightening process and resulting in higher costs. Summary of the Utility Model

[0005] In order to overcome the deficiencies that in the actual application process of the existing water cooling method for aluminum profiles, the aluminum profiles will be deformed due to the impact force generated by the water flushing, increasing the subsequent straightening process and resulting in higher costs, the embodiment of the present application provides a cooling device for aluminum profile forming. By arranging a cooling ring that rotates relative to it inside the water delivery frame, a stable annular channel is formed between the water delivery frame and the cooling ring through a communication ring groove and a plugging ring. When high-pressure water flows through the gap between the water delivery frame and the cooling ring and sprays out from the four spray pipes, by virtue of the spray pipes deviating from the diameter line of the cooling ring, the reverse acting force when the water flows out is used to push the cooling ring to rotate inside the water delivery frame, facilitating comprehensive cooling around the aluminum profile and not impacting the aluminum profile to cause it to be deformed under pressure.

[0006] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0007] A cooling device for aluminum profile forming, comprising a cooling ring and a water delivery frame, and the water delivery frame is sleeved outside the cooling ring;

[0008] Among them, four water spray pipes are processed on the inner wall of the cooling ring, a communication ring groove is processed on the outer wall of the cooling ring, the axes of the four water spray pipes deviate from the diameter line of the cooling ring, and the axis of the water spray pipe is parallel to the diameter line of the cooling ring.

[0009] In a possible implementation manner, the water delivery frame includes a first ring frame and a second ring frame. The first ring frame and the second ring frame are buckled with each other to form a circular ring. An inlet is processed on the outer wall of the first ring frame, and blocking rings are integrally formed on the inner walls of the first ring frame and the second ring frame.

[0010] In a possible implementation manner, the two ends of the first ring frame are fixedly assembled with the two ends of the second ring frame, so that the blocking rings at the inner walls of the first ring frame and the second ring frame are buckled to the inner side of the communication ring groove. The inlet is connected to a high-pressure water pipe. Water enters between the blocking ring and the communication ring groove through the inlet and is simultaneously sprayed out from the interiors of the multiple water spray pipes.

[0011] In a possible implementation manner, a mold frame is arranged on one side of the water delivery frame. An extrusion cylinder is integrally formed on one side of the mold frame. An extrusion outlet is processed inside the mold frame. An aluminum rod is continuously extruded from the interior of the extrusion cylinder through an extruder and formed into an aluminum profile at the extrusion outlet. The aluminum profile passes through the center of the cooling ring, and the water flows sprayed out by the four water spray pipes surround the outer side of the aluminum profile.

[0012] In a possible implementation manner, one ends of the four water spray pipes spray towards the inner side of the cooling ring. By means of the reaction force, the cooling ring rotates inside the water delivery frame, and the inner wall of the cooling ring blocks the water flow from spraying out from the inner side of the cooling ring.

[0013] In a possible implementation manner, strip-shaped grooves are processed at both ends of the blocking ring on the first ring frame, and semi-circular rods are processed at both ends of the blocking ring on the second ring frame. The semi-circular rods are adaptively connected to the interiors of the strip-shaped grooves.

[0014] In a possible implementation manner, fixing rods are processed in the middle of one sides of the first ring frame and the second ring frame. Positioning grooves are processed at the top and bottom of one end of each fixing rod. Two seat sleeves are processed on the surface of one side of the mold frame. Limit screws are threadedly connected to the top and bottom of one end of each of the two seat sleeves. One end of the fixing rod is inserted into the interior of the seat sleeve, and one end of the limit screw abuts against the interior of the positioning groove.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] 1. By arranging a rotatable cooling ring on the inner side of the water delivery frame, a stable annular channel is formed between the water delivery frame and the cooling ring through a communication ring groove and a sealing ring. When high-pressure water flows through the gap between the water delivery frame and the cooling ring and sprays out from the four spray pipes, by virtue of the spray pipes deviating from the diameter line of the cooling ring, the reverse force when the water sprays out can push the cooling ring to rotate on the inner side of the water delivery frame, facilitating comprehensive cooling around the aluminum profile without impacting the aluminum profile and causing it to be deformed under pressure.

[0017] 2. By inserting a fixed rod into the inner part of the seat sleeve and threading a limit screw into the inner part of the seat sleeve and abutting it against the positioning groove inside the fixed rod, it is convenient to fix the water delivery frame and the die holder, supporting the cooling of the cooling ring by the water sprayed out from the spray pipes on the cooling ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0024] Embodiment 1:

[0025] This embodiment introduces the specific structure of a cooling device for aluminum profile forming. Specifically, refer to Figures 1 - 4 shown, including a cooling ring 6 and a water delivery frame 8 sleeved on the outer side of the cooling ring 6. Four spray pipes 7 are processed on the inner wall of the cooling ring 6, a communication ring groove 14 is processed on the outer wall of the cooling ring 6, a die holder 2 is arranged on one side of the water delivery frame 8, an extrusion cylinder 1 is integrally formed on one side of the die holder 2, and an extrusion outlet 3 is processed inside the die holder 2;

[0026] As Figure 1 andFigure 2 As shown in the figure, the water delivery frame 8 includes a first ring frame 801 and a second ring frame 802. The first ring frame 801 and the second ring frame 802 are buckled with each other to form a circular ring. A water inlet 9 is processed on the outer wall of the first ring frame 801. Sealing rings 13 are integrally formed on the inner walls of both the first ring frame 801 and the second ring frame 802;

[0027] Among them, the water inlet 9 is connected to a high-pressure water pipe. When the two ends of the first ring frame 801 and the two ends of the second ring frame 802 are assembled and fixed with bolts, so that the sealing rings 13 at the inner walls of the first ring frame 801 and the second ring frame 802 are buckled to the inner side of the communication ring groove 14, the communication ring groove 14 inside the cooling ring 6 can cooperate with the sealing ring 13, so that water enters between the sealing ring 13 and the communication ring groove 14 through the water inlet 9 and is simultaneously ejected from the interiors of a plurality of spray pipes 7;

[0028] Secondly, the axes of the four spray pipes 7 are all deviated from the diameter line of the cooling ring 6, and the axis of the spray pipe 7 is parallel to the diameter line of the cooling ring 6. By ejecting one ends of the four spray pipes 7 towards the inner side of the cooling ring 6, with the help of the reaction force, the cooling ring 6 can rotate inside the water delivery frame 8, and the inner wall of the cooling ring 6 blocks the water from being ejected from the inner side of the cooling ring 6, and in cooperation with the gravity of the water itself, a water curtain is formed inside the cooling ring 6 to cool the aluminum profile 5, with comprehensive cooling;

[0029] Meanwhile, the aluminum rod is continuously extruded from the inside of the extrusion cylinder 1 by an extruder and formed into an aluminum profile 5 from the inside of the extrusion port 3. The aluminum profile 5 passes through the center of the cooling ring 6. Since the water jets ejected from the four spray pipes 7 surround the outside of the aluminum profile 5, it is possible to avoid applying an impact force to the aluminum profile 5, resulting in deformation of the aluminum profile 5.

[0030] Furthermore, in order to ensure the sealing performance at the connection points of the first ring frame 801 and the second ring frame 802, as Figure 3 and Figure 4 shown, strip-shaped grooves 15 are processed at both ends of the sealing ring 13 on the first ring frame 801, and semi-circular rods 16 are processed at both ends of the sealing ring 13 on the second ring frame 802. By fitting the semi-circular rods 16 into the strip-shaped grooves 15, the fitting degree at the connection points of the two sealing rings 13 is increased, and it is possible to prevent the water inside the communication ring groove 14 from seeping out from the joint of the two sealing rings 13.

[0031] By adopting the above technical solutions:

[0032] The above design sets a cooling ring 6 that rotates relative to the inner side of the water delivery frame 8. A stable annular channel is formed between the water delivery frame 8 and the cooling ring 6 through the communication ring groove 14 and the plugging ring 13. When high-pressure water is delivered to the annular channel through the water inlet 9 on the outer wall of the water delivery frame 8, the water sprays out from the inside of the four spray pipes 7 on the inner wall of the cooling ring 6. By means of the spray pipes 7 deviating from the diameter line of the cooling ring 6, the reverse acting force when the water sprays out pushes the cooling ring 6 to rotate on the inner side of the water delivery frame 8, facilitating the water sprayed from the four spray pipes 7 to form a water curtain on the inner side of the cooling ring 6 (the water sprayed from the spray pipes 7 interferes with each other and is blocked by the inner wall of the cooling ring 6), and comprehensively cooling the aluminum profile 5 passing through the center of the cooling ring 6. During this process, the water does not directly impact the aluminum profile 5, and the aluminum profile 5 will not be deformed due to the impact.

[0033] Embodiment 2:

[0034] Based on Embodiment 1, this embodiment introduces the specific structure between the water delivery frame 8 and the die holder 2, as Figure 1 and Figure 2 shown, fixing rods 11 are machined in the middle of one side of the first ring frame 801 and the second ring frame 802. Positioning grooves 12 are machined at the top and bottom of one end of the fixing rod 11. Two seat sleeves 10 are machined on the surface of one side of the die holder 2. Limit screws 4 are threadedly connected to the top and bottom of one end of the two seat sleeves 10;

[0035] Among them, by inserting one end of the fixing rod 11 into the inside of the seat sleeve 10 and adjusting the threaded connection between the limit screw 4 and the seat sleeve 10 so that one end of the limit screw 4 abuts against the inside of the positioning groove 12, the water delivery frame 8 can be fixed to one side of the die holder 2 to support the extrusion of the aluminum rod from the inside of the extrusion port 3, so that the aluminum profile 5 passes through the center of the cooling ring 6.

[0036] By adopting the above technical solution:

[0037] The above design, by inserting the fixing rod 11 into the inside of the seat sleeve 10, when adjusting the threaded connection between the limit screw 4 and the seat sleeve 10 so that one end of the limit screw 4 abuts against the inside of the positioning groove 12 on the fixing rod 11, the fixing rod 11 and the seat sleeve 10 can be connected and fixed, facilitating the fixing of the water delivery frame 8 and the die holder 2, enabling the aluminum profile 5 to pass through the inner side of the cooling ring 6, and supporting the cooling ring 6 to rotate on the inner side of the water delivery frame 8 under the influence of the water sprayed from the spray pipes 7.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
