Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and in particular relates to a forming die for processing automobile longitudinal beams. Background Art

[0002] As a key component of the automobile body structure, the quality of the automobile longitudinal beam directly affects the overall performance and safety of the automobile. In the manufacturing process of automobile longitudinal beams, die stamping is a common forming process. However, in the traditional stamping process, due to the large stamping force and high speed, the die is prone to high temperature during the stamping process, which not only affects the service life of the die, but also may cause the quality of the processed longitudinal beam to be unstable. Therefore, how to effectively control the temperature during the die stamping process has become an urgent problem to be solved in the development of technology.

[0003] Although cooling systems are used in the prior art to cool the mold, these systems are often slow to respond, and the cooling effect is difficult to meet the rapid cooling requirements of the instantaneous high temperature during the rapid stamping process. In addition, the existing cooling system design is not integrated enough, resulting in a complex mold structure and difficult maintenance, which affects production efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a forming mold for processing automobile longitudinal beams, which can achieve rapid response at the moment of stamping, realize instant cooling of the mold, avoid damage to the mold caused by high temperature, and improve the convenience of mold maintenance by simplifying the circulation path of the coolant, thereby improving production efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A forming die for processing an automobile longitudinal beam comprises a die body, wherein a cooling mechanism is arranged inside the die body;

[0007] The cooling mechanism comprises a connecting plate, to which a pressurizing member, a first base and a second base are connected;

[0008] The first base and the second base are distributed on both sides of the pressurizing member;

[0009] A first connecting pipe is connected between the first base and the pressurizing member, and a second connecting pipe is connected between the second base and the pressurizing member;

[0010] A liquid storage bin is provided inside the pressurizing member, and a hydraulic cylinder is connected to the inside of the pressurizing member. A push plate is connected to the telescopic end of the hydraulic cylinder, and the push plate is located in the liquid storage bin.

[0011] Furthermore, a second liquid inlet pipe is connected to one side of the top of the liquid storage bin, and the second liquid inlet pipe is connected to the first connecting pipe.

[0012] Furthermore, a second liquid drain pipe is connected to the bottom of the liquid storage bin.

[0013] Furthermore, a reflux pipe is provided in the pressurizing member, and the reflux pipe is connected to the second connecting pipe.

[0014] Furthermore, the hydraulic cylinder is connected to a hydraulic pipe, and one end of the hydraulic pipe is connected to a hydraulic valve.

[0015] Furthermore, the first base is connected to a first liquid inlet pipe, and the second base is connected to a first liquid outlet pipe;

[0016] One end of the first liquid inlet pipe and one end of the first liquid outlet pipe are both connected to a control valve.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The built-in cooling mechanism can respond in real time during the stamping process and quickly reduce the temperature of the mold. This design solves the problem of slow cooling response speed in the prior art and effectively avoids damage to the mold caused by high temperature, thereby extending the service life of the mold and ensuring the processing quality of the automobile longitudinal beam.

[0019] The cooling mechanism inside the mold body achieves a fast and effective cooling effect by optimizing the flow path of the coolant. This design simplifies the structure of the mold, facilitates maintenance, improves production efficiency, and also ensures that the high temperature generated instantly during the rapid stamping process is effectively controlled, ensuring the stable quality of the processed parts.

[0020] The coordinated work of the liquid storage tank, hydraulic cylinder and push plate in the cooling mechanism enables the coolant to provide sufficient cooling immediately when the mold is stamping, solving the problem that the traditional cooling method cannot provide sufficient cooling at the moment of stamping. This instant response cooling method greatly improves the cooling efficiency and reduces mold damage and product defects caused by improper temperature control.

[0021] The design of hydraulic pipes and control valves in the mold provides precise control of the entire cooling system. By finely controlling the flow of coolant, the present invention not only improves the response speed of the cooling system, but also improves the cooling effect, meeting the strict requirements of high-speed stamping process on cooling speed, which is difficult to achieve in traditional cooling system design.

[0036] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0037] See also Figure 1-4 A forming die for processing a longitudinal beam of an automobile comprises a die body 1, wherein a cooling mechanism 2 is arranged inside the die body 1; the cooling mechanism 2 is specially designed to respond in real time during the stamping process and quickly reduce the temperature inside the die to protect the die from high temperature damage, extend the service life of the die, and ensure the processing quality of the longitudinal beam; the design of the cooling mechanism 2 fully considers the problem of slow response of the cooling system in the prior art, and achieves a fast and effective cooling effect by optimizing the flow path of the coolant;

[0038] The cooling mechanism 2 includes a connecting plate 21, to which a pressurizing member 24, a first base 22 and a second base 23 are connected; the connecting plate 21 not only serves as a supporting structure, but its design also takes into account the flow and distribution of the coolant, ensuring that the entire mold body 1 can be cooled evenly and quickly; the first base 22 and the second base 23 are distributed on both sides of the pressurizing member 24, providing stable support and providing a path for the circulation of the coolant;

[0039] A first connecting pipe 222 is connected between the first base 22 and the pressurizing member 24, and a second connecting pipe 232 is connected between the second base 23 and the pressurizing member 24; the first connecting pipe 222 and the second connecting pipe 232 are designed to control the flow direction of the coolant to ensure that the coolant can quickly reach the area that needs to be cooled during the die stamping process;

[0040] A liquid storage tank 241 is provided inside the pressure member 24, and a hydraulic cylinder 27 is connected inside the pressure member 24, and a push plate 271 is connected to the telescopic end of the hydraulic cylinder 27, and the push plate 271 is located inside the liquid storage tank 241; the design of the liquid storage tank 241 takes into account the storage and rapid release of the coolant, ensuring that sufficient coolant can be provided immediately when the mold is stamping; the design of the hydraulic cylinder 27 and the push plate 271 enables the coolant to be forced to quickly flow into the cooling pipe of the mold at the moment of stamping, thereby achieving a rapid cooling effect;

[0041] See also Figure 4 A second liquid inlet pipe 2413 is connected to one side of the top of the liquid storage tank 241, and the second liquid inlet pipe 2413 is interconnected with the first connecting pipe 222; the design of the second liquid inlet pipe 2413 enables the coolant to refill the liquid storage tank 241 when the mold is closed, preparing for the next stamping cycle.

[0042] See also Figure 4 The bottom of the liquid storage tank 241 is connected with a second drain pipe 2411; the design of the second drain pipe 2411 is a key part of the mold cooling system, which ensures that the coolant can flow out quickly at the moment of mold stamping, thereby achieving instant cooling of the stamping area.

[0043] See also Figure 4 A return pipe 2412 is provided in the pressurizing member 24, and the return pipe 2412 is connected to the second connecting pipe 232; the setting of the return pipe 2412 ensures that the coolant can quickly return after stamping to prepare for the next cycle. Such a circulation system design greatly improves the cooling efficiency and reduces the waste of coolant;

[0044] See also Figure 2-3The hydraulic cylinder 27 is connected to a hydraulic pipe 25, and one end of the hydraulic pipe 25 is connected to a hydraulic valve 251; the design of the hydraulic pipe 25 and the hydraulic valve 251 allows precise control of the hydraulic cylinder 27, ensuring that the push plate 271 can push the coolant at an appropriate speed and force to adapt to different stamping conditions.

[0045] See also Figure 2 A first liquid inlet pipe 221 is connected to the first base 22, and a first liquid discharge pipe 231 is connected to the second base 23; one end of the first liquid inlet pipe 221 and the first liquid discharge pipe 231 are both connected to a control valve 26; the addition of the control valve 26 provides fine control over the flow of the coolant, ensuring that the coolant can enter and leave the mold body 1 at the appropriate time and at the appropriate speed. This design effectively improves the response speed and cooling effect of the cooling system, and meets the strict requirements of the high-speed stamping process on the cooling speed.

[0046] The working principle of the utility model is:

[0047] When in use, the coolant will enter the first connecting pipe 222 from the first liquid inlet pipe 221, and then enter the liquid storage tank 241 through the second liquid inlet pipe 2413. When the coolant of a suitable volume is accumulated in the liquid storage tank 241, the hydraulic cylinder 27 will push the push plate 271 to move downward at the moment of stamping. As the push plate 271 applies pressure, the coolant in the liquid storage tank 241 will quickly flow from the second liquid discharge pipe 2411 located at the bottom of the liquid storage tank 241 into the cooling pipe inside the mold body 1 at the moment of stamping, thereby cooling the mold at the moment of stamping to avoid damage to the mold caused by the high temperature generated during stamping. The coolant that enters the mold through the second liquid discharge pipe 2411 will eventually flow into the second connecting pipe 232 through the reflux pipe 2412 and be discharged through the first liquid discharge pipe 231.

[0048] When the mold completes a single stamping, the coolant will accumulate in the liquid storage tank 241 during the rising process to prepare for the cooling work during the next flushing. In this way, the high temperature generated at the moment of stamping can be avoided from damaging the mold.

[0049] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
