Description

Technical Field

[0001] The invention relates to the technical field of production and processing of mobile phone battery covers, in particular to a one-step forming punching die for mobile phone battery covers. Background Art

[0002] During the production process of mobile phone battery covers, it is necessary to use a mold to punch out the mobile phone battery covers to remove the excess parts around the battery covers.

[0003] The existing one-step forming punching die for mobile phone battery covers often uses four cutters corresponding to the four sides of the battery cover to cut simultaneously. In order to avoid collision and interference between the cutters, the length of the cutters is designed to be slightly smaller than the side length of the product. Although this will prevent collision, there is a situation where the waste edge of the battery cover cannot be completely removed, resulting in the waste edge not being completely cut off and still requiring subsequent processing. To this end, we propose a one-step forming punching die for mobile phone battery covers. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention effectively drives the forward and reverse screw rods to rotate by rotating the handle at one end of the forward and reverse screw rods, thereby driving a group of knife racks symmetrically mounted on the surfaces of the forward and reverse screw rods to move closer to each other until the spacing between the cutters of the group one is the same as the width of the mobile phone battery cover semi-finished product to be punched.

By removing the screws, the limit plate and the slot frame can be easily separated. At this time, the slot frame, T-frame and punching assembly can be removed, which is convenient for inspection and replacement of parts. BRIEF DESCRIPTION OF THE DRAWINGS

In the present invention, the mobile phone battery cover semi-finished body 1003 is matched and placed inside the lower mold 1002, thereby realizing the limitation of the mobile phone battery cover semi-finished body 1003, and then the lower mold 1002 is placed inside the limiting groove 1001, and the movable plate 1004 is rotated so that the bottom of the movable plate 1004 fits with the upper surfaces on both sides of the lower mold 1002, thereby preventing the lower mold 1002 from moving up. Different specifications of lower molds 1002 can be replaced according to different specifications of mobile phone battery cover semi-finished bodies 1003, thereby improving the practicality of the device.

[0030] See also Figure 3-6The present invention provides a technical solution: a one-time forming punching die for a mobile phone battery cover, a limiting mechanism 8 including a fixing rod 801, two groups of fixing rods 801 are symmetrically fixed to the bottom of the support plate 5, the bottom end of the fixing rod 801 is fixedly connected to the limiting plate 802, the bottom end of the limiting plate 802 is fixedly connected to a clamping rod 803, the bottom of the limiting plate 802 is affixed to a slot frame 804, the limiting plate 802 and the slot frame 804 are connected by screws 805, a T-shaped frame 806 is clamped inside the slot frame 804, wherein the clamping rod 803 passes through the top of the slot frame 804 and is clamped into the inner side of the T-shaped frame 806, and the T-shaped frame 806 and the limiting frame 901 are integrally formed. In the present invention, since the clamping rod 803 passes through the top of the slot frame 804 and is clamped into the inner side of the T-frame 806, when the limit plate 802 is connected to the slot frame 804, the clamping rod 803 can effectively limit the T-frame 806 to prevent the T-frame 806 from moving left and right. By removing the screw 805, the limit plate 802 can be easily separated from the slot frame 804. At this time, the slot frame 804, T-frame 806 and punching assembly 9 can be removed, which is convenient for inspection and replacement of parts.

[0031] The punching assembly 9 includes a limit frame 901, which is arranged at the bottom end of the limit mechanism 8. The limit frame 901 is penetrated by a positive and negative screw rod 902 from front to back. A set of tool holders 903 are symmetrically sleeved on the surface of the positive and negative screw rods 902. The positive and negative screw rods 902 and the tool holder 903 are threadedly connected. The top of the tool holder 903 fits the top of the inner side of the limit frame 901. The bottom end of the tool holder 903 is connected to a cutter 904. The limit frame 901 is provided with a positive and negative screw rod 905 from left to right. The positive and negative screw rods 902 and the positive and negative screw rods 905 are fixedly connected at one end. Turn the handle 906, and a set of brackets 907 are symmetrically provided on the surface of the forward and reverse screw rods 905. A knife holder 908 is engaged inside the bracket 907, and the bottom of the knife holder 908 is connected to the cutter 909. Furthermore, the cutter 1 904 and the cutter 909 are matched and fit together, and the bottoms of the cutter 904 and the cutter 909 are flush. The bracket 907 and the knife holder 908 are connected by bolts 910. Furthermore, the forward and reverse screw rods 905 and the bracket 907 are threadedly connected, and the knife holder 908 forms a detachable structure with the bracket 907 through the bolts 910. The present invention effectively drives the forward and reverse screw rod 1 902 to rotate by rotating the handle 906 at the end of the forward and reverse screw rod 1 902, thereby driving a group of tool holders 1 903 symmetrically arranged on the surface of the forward and reverse screw rod 1 902 to move closer to each other until the spacing between a group of cutters 1 904 is the same as the width of the mobile phone battery cover semi-finished product 1003 to be punched. After the width of the mobile phone battery cover semi-finished product 1003 is determined, the tool holder 2 908 of the corresponding specification is clamped into the interior of the clamping frame 907 and effectively fixed by the bolt 910. At this time, the cutter 1 904 and the cutter 2 909 are matched and fit together. Then, by rotating the handle 906 at the end of the forward and reverse screw rods 905, the forward and reverse screw rods 905 are effectively driven to rotate, thereby driving a group of brackets 907 symmetrically arranged on the surface of the forward and reverse screw rods 905 to move away from or approach each other, thereby realizing the adjustment of the distance between a group of cutters 909, which is convenient for adjusting the distance between a group of cutters 909 to the same length as the semi-finished mobile phone battery cover body 1003 to be punched. After the adjustment is completed, there will be no collision or interference between the cutter 1 904 and the cutter 2 909, and the semi-finished mobile phone battery cover body 1003 can be fully punched.

[0032] Working principle: Place the semi-finished mobile phone battery cover body 1003 to be punched into the lower mold 1002 to limit the semi-finished mobile phone battery cover body 1003. Then place the lower mold 1002 into the limiting groove 1001. Rotate the movable plate 1004 so that the bottom of the movable plate 1004 fits with the upper surfaces of both sides of the lower mold 1002, thereby preventing the lower mold 1002 from moving up. The semi-finished mobile phone battery cover body 1003 of different specifications can be replaced. The lower mold 1002 of the same specification is driven to rotate by turning the handle 906 at the end of the positive and negative screw rod 1 902, thereby driving a set of tool holders 1 903 symmetrically arranged on the surface of the positive and negative screw rod 1 902 to move closer to each other until the spacing between a set of cutters 1 904 is the same as the width of the semi-finished mobile phone battery cover body 1003 to be punched. After the width of the semi-finished mobile phone battery cover body 1003 is determined, the tool holder 2 908 of the corresponding specification is clamped into the inside of the clamping frame 907 , and fixed by bolts 910. At this time, the cutter 1 904 and the cutter 2 909 are matched and fitted together. Then, the handle 906 at the end of the forward and reverse screw rod 2 905 is rotated to drive the forward and reverse screw rod 2 905 to rotate, thereby driving a group of brackets 907 symmetrically arranged on the surface of the forward and reverse screw rod 2 905 to move away from or approach each other, thereby realizing the adjustment of the distance between a group of cutters 909, making it easy to adjust the distance between a group of cutters 909 to the semi-finished mobile phone battery cover body 1003 to be punched. The same length, then the support plate 5 is driven downward by the hydraulic cylinder 4, so that the cutter 1 904 and the cutter 2 909 contact the semi-finished body 1003 of the mobile phone battery cover to complete the punching, and the cooperation between the guide cylinder 6 and the spring 7 is used to buffer the support plate 5, thereby performing corresponding buffering on the punching assembly 9. Subsequently, the limit plate 802 can be separated from the slot frame 804 by removing the screws 805, thereby removing the slot frame 804, the T-frame 806 and the punching assembly 9, which is convenient for inspection and replacement of parts.
