Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to a stainless steel pipe casting device. Background Technology

[0002] In the field of stainless steel pipe casting, existing casting equipment has many limitations in practical applications. On the one hand, the finished stainless steel pipes are at high temperatures. Direct removal can easily cause burns and other safety accidents to operators. Furthermore, the low hardness of the high-temperature pipes can lead to surface damage from direct contact, affecting product quality. On the other hand, existing equipment lacks efficient discharge structures, often requiring operators to use additional tools to remove the pipes. This is not only cumbersome and labor-intensive, but also carries the risk of pipe deformation and breakage due to improper handling, severely impacting production efficiency and product qualification rates. In addition, traditional casting equipment relies heavily on natural cooling or simple air cooling, resulting in slow cooling rates, prolonged production cycles, and increased production costs.

[0003] Therefore, those skilled in the art have provided a stainless steel pipe casting apparatus to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stainless steel pipe casting device that features efficient cooling and safe material discharge. Closed-loop cooling accelerates temperature reduction and shortens the production cycle; automatic material discharge avoids burns, reduces pipe damage, and improves production efficiency and product quality.

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

[0006] A stainless steel pipe casting device includes a base, the base having a water storage space and a water pump inside, and a casting mechanism fixedly mounted on the upper end of the base. The casting mechanism includes:

[0007] An inner casting cylinder, the lower opening of which is connected to the output end of a water pump inside the base via a pipe;

[0008] An outer casting cylinder and an inner casting cylinder form a stainless steel tube casting space. A lifting ring is slidably provided between the outer casting cylinder and the inner casting cylinder near the lower end.

[0009] The outer protective cylinder is connected at its lower end to the output end of the water pump inside the base via a pipe between the outer protective cylinder and the outer casting cylinder.

[0010] A solenoid valve is installed through the lower end of the side wall of the outer casting cylinder. When the solenoid valve is opened, it can connect the space between the outer casting cylinder and the inner casting cylinder with the space between the outer protective cylinder and the outer casting cylinder.

[0011] The lower ends of the inner casting cylinder, outer casting cylinder, and outer protective cylinder are fixedly provided with connecting seats, and the lower ends of the connecting seats are fixedly connected to the base.

[0012] Furthermore, hydraulic cylinders are fixedly installed on both sides of the casting mechanism, and a lifting sealing cover is fixedly installed between the upper ends of the two hydraulic cylinders.

[0013] Furthermore, two liquid cooling pipes are provided through the upper end of the lifting sealing cover, with one end of each pipe connected to the internal space of the inner casting cylinder and the space between the outer protective cylinder and the outer casting cylinder, respectively.

[0014] Furthermore, the other ends of both liquid cooling pipes are connected to the water storage space inside the base, and a cooling device is fixedly installed at the front end of the base to cool the coolant inside the water storage space.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a stainless steel pipe casting device. Through an internal cooling circulation system, a water pump inside the base pumps coolant into the inner casting cylinder and the space between the outer casting cylinder and the outer protective cylinder. The coolant then circulates back into the base via liquid cooling pipes. Simultaneously, cooling equipment further cools the coolant, forming a closed-loop cooling circuit. Compared to traditional cooling methods, this significantly improves cooling efficiency and drastically shortens the cooling time of the stainless steel pipe, thereby effectively increasing overall production efficiency and reducing production costs.

[0017] 2. This utility model proposes a stainless steel pipe casting device. After the stainless steel pipe has cooled, a solenoid valve is opened to introduce coolant into the lower end of a lifting ring. The force of the coolant drives the lifting ring to rise slowly, thus automatically lifting the stainless steel pipe. This discharge method eliminates the need for operators to directly contact the high-temperature pipe, avoiding the risk of burns. It also reduces damage to the pipe caused by manual operation, ensuring product quality. Furthermore, it is easy to operate and improves discharge efficiency. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1-4 This utility model provides an embodiment of a stainless steel pipe casting device, including a base 5. The base 5 contains a water storage space and a water pump. The volume of the water storage space is designed according to actual production needs and can store coolant required for multiple casting cooling operations. The power of the water pump is adapted to the coolant circulation path and cooling requirements, ensuring that the coolant circulates at a suitable flow rate. A casting mechanism 1 is fixedly installed on the upper end of the base 5. The casting mechanism 1 includes:

[0026] The inner casting cylinder 101 has its lower opening connected to the output end of the water pump inside the base 5 via a pipe. The principle is that after the water pump starts, it pumps the coolant from the base's water storage space into the inner casting cylinder 101. The coolant flows within the inner casting cylinder 101, absorbing the heat generated inside the stainless steel tube during the casting process, thus cooling the inside of the stainless steel tube. The advantage is that internal cooling effectively reduces the temperature inside the stainless steel tube, resulting in more uniform cooling of the tube and preventing deformation due to excessive temperature differences between the inside and outside, thereby improving product quality.

[0027] An outer casting cylinder 102 forms a stainless steel pipe casting space between itself and an inner casting cylinder 101. A lifting ring 106 is slidably installed near the lower end of the outer casting cylinder 102 and the inner casting cylinder 101. During the casting process, molten stainless steel is injected into this casting space and solidifies into a pipe. After the stainless steel pipe cools, a solenoid valve 105 is opened, and coolant flows into the lower end of the lifting ring 106. The buoyancy and pressure of the coolant push the lifting ring 106 upward, thereby lifting the stainless steel pipe out. Its advantages include automated material discharge, reduced manual operation, avoidance of operator contact with high-temperature pipes, ensuring personal safety, reduced risk of pipe damage due to manual operation, and improved discharge efficiency and product qualification rate.

[0028] The lower end of the outer protective cylinder 103 and the outer casting cylinder 102 is connected to the output end of the water pump inside the base 5 via a pipe. The water pump pumps coolant into the space between the outer protective cylinder 103 and the outer casting cylinder 102. The coolant circulates within this space, absorbing heat from the outside of the stainless steel pipe and providing auxiliary cooling. This structure can further improve cooling efficiency, accelerate the overall cooling speed of the stainless steel pipe, shorten the production cycle, and the outer protective cylinder 103 can also provide a certain degree of protection during the casting process, preventing external factors from affecting the casting quality.

[0029] A solenoid valve 105 is installed through the lower end of the side wall of the outer casting cylinder 102. When the solenoid valve 105 is open, it connects the space between the outer casting cylinder 102 and the inner casting cylinder 101 with the space between the outer protective cylinder 103 and the outer casting cylinder 102. During the stainless steel pipe cooling stage, the solenoid valve 105 is closed to ensure independent cooling of each cooling space. After cooling is complete, the solenoid valve 105 is opened to allow the coolant to flow between the spaces, providing upward power for the lifting ring 106 and realizing the discharge function. Its advantages are that the switching between cooling and discharge functions can be achieved by controlling the opening and closing of the solenoid valve 105, the structure is simple, the operation is convenient, and the practicality and reliability of the device are improved. A connecting seat 104 is fixedly installed at the lower end of the inner casting cylinder 101, the outer casting cylinder 102, and the outer protective cylinder 103. The lower end of the connecting seat 104 is fixedly connected to the base 5 to ensure that the casting mechanism is stably installed on the base and to ensure the stability of the casting process.

[0030] Hydraulic cylinders 4 are fixedly installed on both sides of the casting mechanism 1. The thrust of the hydraulic cylinders 4 is designed according to the weight and operating requirements of the lifting sealing cover 2 and related components, and can stably drive the lifting sealing cover 2 to rise and fall. The lifting sealing cover 2 is fixedly installed between the upper ends of the two hydraulic cylinders 4. Two liquid cooling pipes 3 are installed through the upper end of the lifting sealing cover 2. One end of the two liquid cooling pipes 3 is connected to the internal space of the inner casting cylinder 101 and the space between the outer protective cylinder 103 and the outer casting cylinder 102, respectively. The other end of the two liquid cooling pipes 3 is connected to the water storage space inside the base 5. A cooling device 6 is fixedly installed at the front end of the base 5. The cooling device 6 cools the coolant inside the water storage space. The principle is that during the casting process, the hydraulic cylinders 4 drive the lifting sealing cover 2 to descend, sealing the casting mechanism to prevent heat loss and the entry of external impurities. The coolant circulates under the action of the water pump, absorbs heat, and then flows back to the water storage space of the base through the liquid cooling pipes 3. The cooling device 6 cools the heated coolant so that it can participate in the circulation cooling again. The advantage lies in the sealing of the casting space through the oil cylinder 4 and the lifting sealing cover 2, which improves the cooling effect. At the same time, the circulation of coolant and the cooling effect of the cooling equipment 6 ensure continuous and efficient cooling capacity, effectively shorten the cooling time of stainless steel pipes, and improve production efficiency.

[0031] Working Principle: During stainless steel pipe casting, molten stainless steel is first injected into the casting space formed between the outer casting cylinder 102 and the inner casting cylinder 101. At this time, the water pump inside the base 5 is activated, pumping coolant from the water storage space into the inner casting cylinder 101 and the space between the outer casting cylinder 102 and the outer protective cylinder 103. The coolant absorbs the heat generated during the casting process, providing initial cooling to the stainless steel pipe. Simultaneously, after absorbing heat, the coolant flows back to the water storage space inside the base 5 through the liquid cooling pipe 3 on the lifting sealing cover 2. The cooling equipment 6 then cools the heated coolant, restoring its cooling capacity, thus achieving coolant recycling.

[0032] After the stainless steel tube has cooled, the solenoid valve 105 at the lower end of the side wall of the outer casting cylinder 102 is opened. At this time, the space between the outer casting cylinder 102 and the inner casting cylinder 101 is connected to the space between the outer protective cylinder 103 and the outer casting cylinder 102. Under the action of gravity and water pump pressure, the coolant flows into the lower end of the lifting ring 106. As the coolant is continuously injected, the lifting ring 106 slowly rises under the buoyancy and pressure of the coolant, thereby lifting the cast stainless steel tube upwards and completing the discharge process. The entire working process realizes the automation and integration of cooling and discharge, improving the efficiency and quality of casting production.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
