DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-5 The utility model provides a technical solution for a notebook shell stamping device: Example

A lower mold 2 is vertically slidably mounted on the top of the bottom table 11 through a lower mold pushing unit 3, and a hydraulic cylinder 5 is vertically connected to the center of the bottom of the top table 12. The output end of the hydraulic cylinder 5 is vertically slidably mounted on an upper mold 4 through an upper mold pushing unit 6. The lower mold 2 is composed of a lower mold plate 21 and a lower punch 22, and the upper mold 4 is composed of an upper mold plate 41 and an upper mold cavity 42. The lower mold 2 matches the upper mold 4. After the lower mold 2 and the upper mold 4 are assembled, the lower punch 22 and the upper mold cavity 42 can cooperate with each other. A stamping cavity for forming a notebook shell is provided with a cutting knife 43 below the upper die 4. The cutting knife 43 is a rectangular structure and is located at the edge of the lower die cavity. The cutting size of the cutting knife 43 is consistent with the size of the aluminum plate to be formed for the notebook shell. The hydraulic cylinder 5 is extended to drive the upper die 4 to move downward. When the hydraulic cylinder 5 is extended to the maximum extension, the aluminum material can be directly cut into a fixed size into the aluminum plate to be formed for the notebook shell through the cutting knife 43. The cut aluminum plate is located between the lower die 2 and the upper die 4. The lower die 2 and the upper die 4 can realize automatic positioning of the aluminum plate, cancel the setting of the positioning mechanism in the subsequent forming and stamping process, simplify the processing device, reduce the equipment cost, and facilitate operation.

[0023] like Figure 2 and Figure 3 As shown, the lower mold pushing unit 3 includes a cavity opened in the center of the base 11, and a lower piston plate 32 is matched and mounted in the cavity. The lower part of the lower piston plate 32 is sealed with the cavity to form a lower oil chamber 31, and the upper part of the lower piston plate 32 is connected to the bottom of the lower template 21 through a lower push column 33. A guide groove 34 is vertically and symmetrically opened in the base 11, and a lower guide column 35 is vertically and symmetrically connected to the lower template 21, and the lower guide column 35 is vertically slidably mounted in the guide groove 34. Through the guiding effect of the guide member composed of the guide groove 34 and the lower guide column 35, the lower mold 2 can be stably moved up and down on the base 11; The mold pushing unit 6 includes an upper oil cylinder 61 fixed below the output end of the hydraulic cylinder 5, and an upper piston plate 62 is matched and sleeved in the upper oil cylinder 61. An upper oil chamber 63 is sealed between the upper piston plate 62 and the upper oil cylinder 61, and the lower part of the upper piston plate 62 is connected to the upper mold plate 41 through an upper push column 64. Guide sleeves 66 are symmetrically fixed on both sides of the upper oil cylinder 61, and upper guide columns 65 are vertically symmetrically connected above the upper mold plate 41, and the upper guide columns 65 are slidably sleeved on the guide sleeves 66. Through the guiding action of the guide member 2 composed of the guide sleeve 66 and the lower guide column 35, the upper mold 4 can be stably moved up and down below the top platform 12.

[0024] according to Figure 3As shown, it also includes a pumping assembly 7, which includes an auxiliary oil chamber 72 opened in the base 11, the auxiliary oil chamber 72 is connected to the lower oil chamber 31 through a guide tube 73, and the auxiliary oil chamber 72 is connected to the upper oil chamber 63 through an oil pipe 74, and an oil pump 71 is installed on the oil pipe 74, the upper oil chamber 63, the lower oil chamber 31 and the auxiliary oil chamber 72 are all filled with hydraulic oil, and the maximum capacity of the upper oil chamber 63 is equal to or greater than the sum of the capacities of the auxiliary oil chamber 72 and the lower oil chamber 31, and the hydraulic oil pump 71 in the lower oil chamber 31 and the auxiliary oil chamber 72 can be sent to the upper oil chamber 63 by the oil pump 71, and the hydraulic oil pump 71 in the upper oil chamber 63 can also be sent to the auxiliary oil chamber 72 and the lower oil chamber 31. By transferring the hydraulic oil between the upper oil chamber 63 and the lower oil chamber 31, the upper mold 4 and the lower mold 2 can operate synchronously, and due to the setting of the auxiliary oil chamber 72, after all the hydraulic oil in the lower oil chamber 31 and the auxiliary oil chamber 72 enters the upper oil chamber 63, the hydraulic oil in the auxiliary oil chamber 72 will be replenished into the upper oil chamber 63, so that the movement of the upper mold 4 is greater than the movement of the lower mold 2, and the excess movement is exactly equal to the depth of the cutting knife 43. When the lower mold 2 contacts the base 11, the upper mold 4 will continue to move and fit with the lower mold 2 to complete the forming and stamping. Through the mutual cooperation of the above-mentioned structures, the cutting, forming and stamping of the notebook shell can be realized continuously, simplifying the processing steps.

[0025] The lower template 21 is provided with a clearance groove 23 corresponding to the position of the cutting knife 43. When the lower mold 2 and the upper mold 4 are completely assembled together to stamp the aluminum plate, the cutting knife 43 can extend into the clearance groove 23. The clearance groove 23 provides an accommodation space for the cutting knife 43, so that the upper mold 4 and the lower mold 2 can be smoothly assembled and stamped.

[0026] When used specifically, the utility model provides a notebook shell stamping processing device, and the stamping processing workflow is as follows: Figure 5As shown, before stamping, the hydraulic oil in the lower oil chamber 31 is at the maximum oil volume, the lower mold 2 is away from the bottom platform 11 by a certain distance, the aluminum material is transferred to the processing table 1 and is located on the lower mold 2, and then the hydraulic cylinder 5 is controlled to operate and extend, pushing the upper mold 4 and the upper mold pushing unit 6 to move downward. When the hydraulic cylinder 5 is extended to the longest, the cutting knife 43 can cut the aluminum material on the lower mold 2 and cut the aluminum material into an aluminum plate with the same size as the notebook shell. At this time, the cut aluminum material is between the lower mold 2 and the upper mold 4, and the cutting knife 43 is about to enter the yield knife The oil pump 71 then operates to pump all the hydraulic oil in the lower oil chamber 31 and the auxiliary oil chamber 72 into the upper oil chamber 63. As the amount of oil in the lower oil chamber 31 decreases, the amount of oil in the upper oil chamber 63 increases. The upper mold 4 and the lower mold 2 move downward at the same time. When the lower mold 2 contacts the bottom platform 11, it stops moving. The oil pump 71 continues to operate, and the amount of oil in the upper oil chamber 63 continues to increase. The upper mold 4 continues to move downward until it is assembled with the lower mold 2. Then, with the cooperation of the lower mold 2 and the upper mold 4, the aluminum plate is stamped to form the aluminum plate into a notebook shell.

[0027] Then the oil pump 71 reverses the pumping of oil to pump the oil in the upper oil chamber 63 into the auxiliary oil chamber 72 and the lower oil chamber 31, and the upper mold 4 and the lower mold 2 move upward. At the same time, the hydraulic cylinder 5 contracts, driving the upper mold 4 to move upward again, and finally the notebook shell stamped on the lower mold 2 is removed, completing the integrated stamping work of cutting and forming the notebook shell.
