Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water seal devices, and in particular to a water seal device for a profile extrusion equipment. Background Technology
[0002] After aluminum profiles are extruded from the extruder, they are in a high-temperature plastic state. If they are cooled slowly (such as by air cooling), it may lead to coarse grains and a decrease in mechanical properties. However, water immersion cooling can quickly remove heat through the high specific heat capacity and fluidity of water, creating an "online quenching" effect, which can significantly improve the strength and hardness of the profiles.
[0003] Therefore, the discharge end of current aluminum profile extrusion presses is connected to a water cooling tank. After extrusion, the profile directly enters the tank for cooling. The tank uses a circulating water or spray system to quickly cool the profile, thus replacing the traditional air cooling method to improve cooling efficiency and profile mechanical properties.
[0004] To ensure the continuity of aluminum profile extrusion, the discharge pipe of the aluminum profile extruder is directly connected to the receiving pipe of the cooling water tank. This causes the cooling water in the cooling water tank to flow back from the discharge pipe into the aluminum profile extruder. This not only causes the profile to come into premature contact with the cooling water, affecting its performance, but also damages the aluminum profile extruder. Utility Model Content
[0005] The purpose of this utility model is to provide a water seal device in a profile extrusion equipment, which uses cooling water to form a water seal between the discharge end of the extruder and the receiving end of the cooling water tank, so as to solve the problem of backflow of cooling water in the cooling water tank.
[0006] To solve the above-mentioned technical problems, this utility model provides a water seal device in a profile extrusion equipment, which is installed between the extruder and the cooling water tank. It includes a main material pipe, one end of which is connected to a receiving pipe and connected to the discharge end of the extruder through the receiving pipe; the other end is connected to a feeding pipe and connected to the inlet of the cooling water tank through the feeding pipe.
[0007] The extruded profiles pass through the receiving pipe, main material pipe and feeding pipe in sequence before entering the cooling water tank;
[0008] The main material pipe is provided with a water jacket assembly and an inlet pipe connected to the water jacket assembly at one end near the receiving pipe. The cooling water continuously supplied by the inlet pipe passes through the water jacket assembly, the main material pipe, and the feeding pipe in sequence before entering the cooling water tank. After being pressurized by the water jacket assembly, the cooling water impacts the profile in an annular oblique direction to form a water seal.
[0009] Preferably, the water jacket assembly includes an outer water jacket and an inner water jacket, the outer water jacket and the inner water jacket are sleeved and installed at the end of the main material pipe, and the cavity between the outer water jacket and the inner water jacket is connected to the water inlet pipe, and the cavity between the inner water jacket and the main material pipe is connected to the inner cavity of the water inlet pipe.
[0010] Preferably, the water jacket assembly is further provided with a combined convex cone and concave cone, and the cooling water is pressurized in the water flow channels of the convex cone and the concave cone and then impacts the profile obliquely.
[0011] Preferably, the convex cone is threaded to the end of the inner water jacket, the concave cone is threaded to the end of the main material pipe, and an inclined water flow channel is formed between the convex cone and the concave cone.
[0012] Preferably, the water flow channel formed between the convex cone and the concave cone is inclined toward the forming direction of the profile, so that the cooling water flowing out of the water flow channel impacts the profile and forms a cone-shaped water seal, thereby preventing the cooling water from flowing back toward the extruder.
[0013] Preferably, the receiving pipe is also equipped with a water baffle plate assembly for cutting off the water flow channel in the direction of the extruder and the receiving pipe.
[0014] Preferably, the water-blocking valve plate assembly includes a mounting bracket, a drive piston cylinder, and a valve plate. The valve plate is vertically arranged above the receiving pipe, and under the action of the drive piston cylinder, the valve plate is driven downward to cut off the water flow channel of the receiving pipe.
[0015] Preferably, a water seal receiving trough is provided on one side of the water jacket assembly, and the water seal receiving trough is connected to the main material pipe above it through a water seal receiving pipe, which is used to receive the cooling water dripping from the water seal.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. The water seal device in this profile extrusion equipment is installed between the extruder and the cooling water tank.

[0018] 2. The water jacket assembly in the water seal device is equipped with a combination of convex and concave cones, and an inclined water flow channel is formed between the two.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example
[0029] This utility model provides a water seal device for a profile extrusion machine, installed between the extruder and the cooling water tank. Please refer to [link / reference]. Figure 1-3 The water seal device includes a main material pipe 1, one end of which is connected to a receiving pipe 2, which is connected to the discharge end of the extruder; the other end is connected to a feeding pipe 3, which is connected to the inlet of the cooling water tank. The profile 100 formed by the extruder passes through the receiving pipe 2, the main material pipe 1, and the feeding pipe 3 in sequence before entering the cooling water tank. A water jacket assembly 4 and a water inlet pipe 5 connected to the water jacket assembly 4 are provided at one end of the main material pipe 1 near the receiving pipe 2. The cooling water continuously supplied by the water inlet pipe 5 passes through the water jacket assembly 4, the main material pipe 1, and the feeding pipe 3 in sequence before entering the cooling water tank. The cooling water is pressurized by the water jacket assembly 4 and impacts the profile 100 in an annular oblique direction to form a water seal.
[0030] Specifically, such as Figure 4 and Figure 5 As shown, the water jacket assembly 4 includes an outer water jacket 401 and an inner water jacket 402. The outer water jacket 401 and the inner water jacket 402 are sleeved and installed at the end of the main material pipe 1. The cavity between the outer water jacket 401 and the inner water jacket 402 is connected to the water inlet pipe 5, and the cavity between the inner water jacket 402 and the main material pipe 1 is connected to the inner cavity of the water inlet pipe 5.
[0031] Furthermore, the water jacket assembly 4 is also provided with a combined convex cone 6 and concave cone 7, and the cooling water is pressurized in the water flow channels of the convex cone 6 and the concave cone 7 and then impacts the profile 100 obliquely.
[0032] The convex cone 6 is threaded to the end of the inner water jacket 402, and the concave cone 7 is threaded to the end of the main material tube 1. An inclined water flow channel is formed between the convex cone 6 and the concave cone 7. The water flow channel formed between the convex cone 6 and the concave cone 7 is inclined toward the forming direction of the profile 100, so that the cooling water flowing out of the water flow channel impacts the profile 100 and forms a cone-shaped water seal, thereby preventing the cooling water from flowing back toward the extruder.
[0033] For details, please refer to the following: Figure 1 and Figure 6 The receiving pipe 2 is also equipped with a water baffle plate assembly 8, which is used to cut off the water flow channel in the direction of the extruder and the receiving pipe 2.
[0034] Furthermore, the water baffle plate assembly 8 includes a mounting bracket 801, a drive piston cylinder 802, and a valve plate 803. The valve plate 803 is vertically arranged above the receiving pipe 2. Under the action of the drive piston cylinder 802, the valve plate 803 is driven downward to cut off the water flow channel of the receiving pipe 2. Before the extruder starts working, the cooling water tank needs to be replenished. At this time, the drive piston cylinder 802 drives the valve plate 803 downward to cut off the water flow channel of the receiving pipe 2. The cooling water enters the cooling water tank after passing through the water jacket assembly 4, the main material pipe 1, and the feeding pipe 3. When the extruder continuously forms aluminum profiles, the water baffle plate assembly 8 is always in the open state and forms a water seal through the convex cone 6 and the concave cone 7.
[0035] Furthermore, a water seal receiving trough 9 is provided on one side of the water jacket assembly 4. The water seal receiving trough 9 is connected to the main material pipe 1 via a water seal receiving pipe 10 above it, and is used to receive the cooling water dripping from the water seal.
[0036] The water seal device in this profile extrusion equipment is installed between the extruder and the cooling water tank. It uses cooling water to form a water seal between the discharge end of the extruder and the receiving end of the cooling water tank to solve the problem of backflow of cooling water in the cooling water tank.
[0037] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
