[0024] The existing upper die 6 contacts and extrudes the iron sheet, the position of the iron sheet contacting the upper die 6 is deformed due to stretching, the friction between the two is larger at this time, and the temperature also rises, thereby affecting the forming quality. In use, first, the iron sheet is placed on the lower die 3 and on the ejector pin 2, then the outer side of the sponge roller 8 is coated with lubricating oil, a pair of sliding plates 9 are driven by the driving mechanism to move along the bottom end of the top plate 4, the movement of the sliding plate 9 drives the roller shaft 7 to move, with the movement of the roller shaft 7, the sponge roller 8 rolls, and the lubricating oil is evenly applied to the bottom end of the upper die 6, then the cylinder 5 drives the upper die 6 to move downward, extruding the iron sheet on the lower die 3, the lower die 3 is stressed and moves downward, extruding the elastic element to deform and generate elastic potential energy, at this time the position of the ejector pin 2 does not change, the edge of the iron sheet is deformed due to stress and stretching, thereby forming a casing. Since there is lubricating oil between the upper die 6 and the iron sheet, the friction during stretching can be effectively reduced, and the stretching effect can be improved. Finally, the cylinder 5 drives the upper die 6 to reset, and the elastic element drives the lower die 3 to reset, and the processed casing is ejected. It should be noted that the elastic element is a prior art and is mature, and will not be described in detail.

[0025] As shown in Figure 3 and Figure 4 , the driving mechanism comprises a power assembly and a transmission assembly, the transmission assembly comprises a connecting plate 10, a winding roller 11 and a nylon rope 12, the connecting plate 10 is fixedly connected with a pair of sliding plates 9, and the nylon rope 12 is fixedly connected between the connecting plate 10 and the winding roller 11.

[0026] When the power assembly is running, the winding roller 11 rotates, which pulls one end of the nylon rope 12, and the nylon rope 12 is stressed to drive the connecting plate 10 to move, the connecting plate 10 moves to drive the sliding plate 9 to move, and the sliding plate 9 moves to finally drive the sponge roller 8 through the roller shaft 7 to roll and coat oil on the bottom end of the upper die 6.

[0027] As shown in Figure 3 and Figure 4 , the power assembly comprises a servo motor 13 and a fixed plate 14, the servo motor 13 is installed on one end of the fixed plate 14 close to the winding roller 11, the output end of the servo motor 13 is fixedly connected with the winding roller 11, and the fixed plate 14 is fixedly connected to the outside of the machining table 1.

[0028] When the servo motor 13 is running, it provides a power source for the winding roller 11 to drive the winding roller 11 to rotate.

[0029] As shown in Figure 3 and Figure 4 , the bottom end of the top plate 4 is fixedly connected with a limiting plate 15, the nylon rope 12 penetrates through the limiting plate 15, and a spring 16 is fixedly connected between the limiting plate 15 and the connecting plate 10.

[0030] In the process of moving the connecting plate 10, the spring 16 is extruded, and the spring 16 is deformed and generates elastic potential energy. After the upper die 6 is processed and reset, the driving of the servo motor 13 to the winding roller 11 is completed. Since the servo motor 13 does not have a locking function, the spring 16 releases the elasticity at this time, and pushes the connecting plate 10 to reset. The connecting plate 10 resets and drives the roller shaft 7 and the sponge roller 8 through the sliding plate 9.

[0031] As shown in Figure 5 The outer side of the top plate 4 is fixedly connected with a liquid storage pipe 17. A one-way valve 18 is mounted on the outer side of the liquid storage pipe 17.

The air pipe 19 is rotatably connected to the inside of the roller shaft 7 away from the liquid storage pipe 17. The sliding plate 9 is provided with a gas pressure mechanism for compressing the air inside the liquid storage pipe 17.

[0032] The one-way valve 18 is used to add lubricating oil inside the liquid storage pipe 17. When the sliding plate 9 moves, the sliding plate 9 drives the gas pressure mechanism to operate synchronously. The operation of the gas pressure mechanism extrudes the lubricating oil inside the liquid storage pipe 17, and transmits the lubricating oil to the inside of the roller shaft 7 through the air pipe 19. The roller shaft 7 adheres to the surface of the sponge roller 8, and timely supplements the lubricating oil for the sponge roller 8. It should be noted that the lubricating oil outside can only enter the inside of the liquid storage pipe 17 through the one-way valve 18, and cannot be discharged from the inside of the liquid storage pipe 17.

[0034] The movement of the sliding plate 9 drives the movement of the piston rod 21. The movement of the piston rod 21 drives the movement of the piston plate 20. The movement of the piston plate 20 extrudes the air inside the liquid storage pipe 17, so that the air pressure increases. The increase of the air pressure inside the liquid storage pipe 17 causes the lubricating oil inside to enter the inside of the air pipe 19.

[0035] Working principle: first, the shell iron sheet is placed in the lower die 3, and is located on the ejector pin 2, then the outside of the sponge roller 8 is coated with lubricating oil, a pair of sliding plates 9 is driven by the driving mechanism to move along the bottom end of the top plate 4, and the sliding plate 9 moves to drive the roller shaft 7 to move, with the movement of the roller shaft 7, the sponge roller 8 rolls, and the lubricating oil is evenly coated on the bottom end of the upper die 6, then the cylinder 5 drives the upper die 6 to move down, extruding the iron sheet on the lower die 3, the lower die 3 is forced to move down and extrude the elastic element, so that the elastic element is deformed and generates elastic potential energy, at this time the position of the ejector pin 2 is unchanged, the edge of the iron sheet is deformed under stress and stretched, thereby forming the shell, because there is lubricating oil between the upper die 6 and the iron sheet, the friction during stretching can be effectively reduced, and the stretching effect is improved, finally, the cylinder 5 drives the upper die 6 to reset, and the elastic element drives the lower die 3 to reset, and the processed shell is ejected;

[0036] When the servo motor 13 is running, it will provide power source for the winding roller 11 to drive the winding roller 11 to rotate, and the winding roller 11 rotates to pull one end of the nylon rope 12, and the nylon rope 12 is forced to move the connecting plate 10, the connecting plate 10 moves to drive the sliding plate 9 to move, and the sliding plate 9 moves to finally drive the sponge roller 8 through the roller shaft 7 to roll the bottom end of the upper die 6;

[0037] During the movement of the connecting plate 10, the spring 16 is extruded to deform and generate elastic potential energy, and after the upper die 6 is processed and reset, the driving of the servo motor 13 to the winding roller 11 is ended, the spring 16 releases the elasticity to push the connecting plate 10 to reset, and the connecting plate 10 resets to drive the roller shaft 7 and the sponge roller 8 to reset through the sliding plate 9;

[0038] The lubricating oil is added to the inside of the liquid storage pipe 17 through the one-way valve 18, when the sliding plate 9 moves, the sliding plate 9 drives the piston rod 21 to move, and the piston rod 21 moves to drive the piston plate 20 to move, the piston plate 20 moves to extrude the air in the inside of the liquid storage pipe 17, so that the air pressure increases, and the lubricating oil in the inside of the liquid storage pipe 17 enters the inside of the air pipe 19, the lubricating oil is transmitted to the inside of the roller shaft 7 through the air pipe 19, and then adheres to the surface of the sponge roller 8 through the roller shaft 7, so as to supplement the lubricating oil for the sponge roller 8 in time.
