Raw aluminum is collectively referred to as electrolytic aluminum in the market supply. It is the raw material for producing aluminum and aluminum alloy materials. Aluminum is a metal with low strength and good plasticity. In addition to the application of pure aluminum, it is alloyed to improve strength or comprehensive performance. Adding an alloy element to aluminum can change its organizational structure and performance, making it suitable for various processed materials or cast parts. Commonly added alloy elements include copper, magnesium, zinc, silicon, etc.

Excessive temperature can easily make the stamped parts more susceptible to wear. Over time, the mobile phone middle frames punched out by the stamped parts may be difficult to meet the required size requirements. Therefore, a stamping device for producing mobile phone middle frames is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the embodiment, Figure 1-4 A stamping device for producing a mobile phone middle frame is provided, comprising a bottom plate 1, a stamping mounting platform 2 is fixedly connected to the top of the bottom plate 1, a stamping assembly 3 is fixedly connected to the top of the stamping mounting platform 2, a cooling assembly 4 for cooling the stamping assembly 3 is arranged on the stamping mounting platform 2, and a stamping bottom die 5 is fixedly connected to the top of the bottom plate 1;

[0023] The stamping installation platform 2 includes a stamping installation base 21 and a top plate 22. The top of the bottom plate 1 is fixedly connected to the stamping installation base 21, and the top of the stamping installation base 21 is fixedly connected to the top plate 22.

[0024] The cooling component 4 includes a circulating water tank 41, a water inlet pipe 42, a drain pipe 43, a cooling pipe 44 and a solenoid valve 45. The circulating water tank 41 is fixedly connected to the stamping mounting base 21. The right end of the circulating water tank 41 is connected to the water inlet pipe 42. The right end of the circulating water tank 41 is connected to the drain pipe 43 located below the water inlet pipe 42. The front end of the circulating water tank 41 is connected to the cooling pipe 44. The cooling pipe 44 is located on the outside of the stamping component 3. Solenoid valves 45 are provided on the outsides of the water inlet pipe 42 and the drain pipe 43.

[0025] Through the above arrangement, the circulating water tank 41 contains a water pump, which can ensure that the water in the cooling pipe 44 and the water in the circulating water tank 41 circulate. First, the metal material is placed inside the stamping bottom die 5, and then the stamping assembly 3 is used to stamp the metal material. After multiple stampings, the water pump starts to work to circulate the water in the circulating water tank 41 and the cooling pipe 44. The water can take away the heat generated by the stamping assembly 3 to avoid the stamping assembly 3 from being too high in temperature. When the water temperature in the circulating water tank 41 gradually rises, the stamping operation is no longer performed. Open the solenoid valve 45 on the outside of the drain pipe 43 to drain the water in the circulating water tank 41, then connect the water inlet pipe 42 to an external water source, open the solenoid valve 45 on the outside of the water inlet pipe 42, and supply water to the circulating water tank 41. After the water supply is completed, the stamping work can continue. A through hole is provided on the circulating water tank 41 to prevent the internal air pressure of the circulating water tank 41 from being too high, making it difficult to supply water to the circulating water tank 41. It should be noted that the cooling pipe 44 is a hose that can be deformed and can move up and down with the stamping assembly 3 without affecting the water circulation in the cooling pipe 44.

[0026] Reference Figure 1-4 , wherein the stamping assembly 3 includes a cylinder 31, a cylinder push rod 32, a mounting plate 33, a stamping top die 34, a guide ring 35, a guide rod 36 and a snap-fit ​​piece 37. The top of the top plate 22 is fixedly connected with the cylinder 31, the inner side of the cylinder 31 is slidably connected with the cylinder push rod 32, one end of the cylinder push rod 32 passes through and extends to the bottom of the top plate 22, the bottom end of the cylinder push rod 32 is fixedly connected with the mounting plate 33, the bottom end of the mounting plate 33 is fixedly connected with the stamping top die 34, the top of the top plate 22 is fixedly connected with two guide rings 35, the inner sides of the two guide rings 35 are slidably connected with guide rods 36, the two guide rods 36 are fixedly connected to the top of the mounting plate 33, the mounting plate 33 is made of heat-conducting material, the front ends of the mounting plate 33 are fixedly connected with four snap-fit ​​pieces 37, the cooling pipe 44 is snapped on the inner sides of the eight snap-fit ​​pieces 37, and the cooling pipe 44 is in contact with the mounting plate 33;

[0027] Through the above-mentioned structural arrangement, the cylinder 31 is started, the cylinder push rod 32 is pushed out, and then the mounting plate 33 and the stamping top die 34 are driven to move downward until the stamping top die 34 stamps the metal material into the middle frame of the mobile phone. When the cylinder push rod 32 is retracted, the mounting plate 33 and the stamping top die 34 are moved up and reset, and the guide ring 35 plays a guiding role to ensure that the cylinder push rod 32 moves in the vertical direction. The mounting plate 33 is a heat-conducting material, which makes it easier to introduce the heat generated by the stamping top die 34 after stamping into the mounting plate 33, and finally cooled by the cooling pipe 44, and the snap-fit ​​piece 37 can fix the cooling pipe 44.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
