DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] A stamping die based on non-ferrous metal processing disclosed in the present invention is mainly applied to existing stamping dies for non-ferrous metal processing. During use, if separation and shaping deformation of the same shape are to be performed, the template of the die needs to be replaced. The template replacement is rather cumbersome and requires disassembly and assembly of the template, which is a large-area operation and a time-consuming and labor-intensive scenario.

[0036] Reference Figure 1-Figure 10 A stamping die based on nonferrous metal processing comprises an upper die base 3 and a lower die base 1, a lower die plate 2 is arranged above the lower die base 1, and an adaption change component 11 is arranged between the lower die base 1 and the lower die plate 2, the adaption change component 11 comprises a placement circular plate 1101 and an adaptation template 1106, and the lower die base 1 is located below the placement circular plate 1101 and is fixedly connected to an iron bottom plate 8, the placement circular plate 1101 is placed above the iron bottom plate 8, cylinders 1117 are distributed in an annular manner on the top of the placement bottom plate, and the output end of each cylinder 1117 is fixedly connected to an expansion rail 1107, and the same intermediate placement plate 1114 is fixedly connected between the multiple expansion rails 1107, and each expansion rail 110 7 One side away from the middle placement plate 1114 is fixedly connected with an end block 1104, and one side of the end block 1104 is fixedly connected with a hydraulic cylinder 1102, the output end of each hydraulic cylinder 1102 is fixedly connected with a clamping plate 1115, the adapter template 1106 is located between the plurality of clamping plates 1115, the bottom of the clamping plate 1115 is fixedly connected with an expansion slider 1116, the expansion slider 1116 is slidably connected to the inside of the corresponding expansion rail 1107, the top of the placement circular plate 1101 is fixedly connected with two connecting rods 1111, and the bottoms of the two connecting rods 1111 are fixedly connected with electromagnets 1110, and the electromagnets 1110 are in contact with the iron bottom plate 8.

[0037] In a specific application scenario, when separating and shaping the same shape of non-ferrous metals, the adapter template 1106 is placed between multiple clamping plates 1115, and the hydraulic cylinder 1102 is adjusted to drive the clamping plate 1115 to clamp the adapter template 1106. Then the adapter template 1106 is placed below the opening position of the lower template 2, and the electromagnet 1110 is energized. The electromagnet 1110 is adsorbed onto the iron bottom plate 8, thereby completing the preliminary installation of the adapter template 1106. The installed adapter template 1106 can fill and change the opening on the lower template 2, so that the lower template 2 can be simultaneously suitable for separation and shaping stamping operations, without the need to replace the lower template 2, thereby saving time and effort and improving the use value of the stamping die.

[0038] Specifically, when the press 4 drives the upper template 9 to perform a plastic deformation type stamping operation on the non-ferrous metal on the lower template 2, the shock-absorbing spring rod 1112 reduces the impact of vibration during the stamping process on the stability of the adapter template 1106, ensuring better cooperation between the adapter template 1106 and the lower template 2.

[0039] It should be noted that when positioning the adapter template 1106, after the electromagnet 1110 is adsorbed onto the iron base plate 8, the hydraulic cylinder 1103 is adjusted to drive the support plate 1108 to move toward the inner wall of the lower die base 1, so that the support plate 1108 is tightly fitted with the inner wall of the lower die base 1, thereby achieving secondary reinforcement of the adapter template 1106 and ensuring its stability during the stamping process.

[0040] Reference Figure 1-Figure 4 In a preferred embodiment, two shock-absorbing spring rods 1112 are fixedly connected to the bottom of each expansion rail 1107, and a contact head 1113 is fixedly connected to the bottom of each shock-absorbing spring rod 1112, and the contact head 1113 is in contact with the iron bottom plate 8. The opposite sides of the two expansion rails 1107 at both ends are fixedly connected to a connecting frame 1105, and the opposite sides of the two connecting frames 1105 are fixedly connected to two hydraulic cylinders three 1103. The output ends of the two hydraulic cylinders three 1103 located on the same connecting frame 1105 are fixedly connected to the same support plate 1108. Two installation grooves are opened on one side of the support plate 1108, and pressure sensors 1109 are fixedly connected to the inside of the two installation grooves.

[0041] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, two mounting columns 10 are fixedly connected to one side of the lower mold base 1, and one end of the two mounting columns 10 is provided with the same limit adjustment component 7, the limit adjustment component 7 includes a mounting seat 701, and the mounting seat 701 is fixedly connected to one end of the two mounting columns 10.

[0042] In the present invention, the top of the mounting seat 701 is fixedly connected with a semicircular adjustment rail 704, the inner arc surface of the semicircular adjustment rail 704 is fixedly connected with a dial 702, the inner sliding connection of the semicircular adjustment rail 704 is connected with an adjustment slider 715, the bottom of the semicircular adjustment rail 704 is fixedly connected with a motor frame 703, the top of the motor frame 703 is fixedly connected with a forward and reverse motor 706, the output shaft of the forward and reverse motor 706 is fixedly connected with a drive shaft 707 through a coupling, the outer side wall of the drive shaft 707 is fixedly connected with a rotating connecting rod 716, the rotating connecting rod 716 is fixedly connected to the top of the adjusting slider 715, and the rotating connecting rod 716 is fixedly connected to the top of the adjusting slider 715. An axle frame 711 is fixedly connected to the top, and sliding rollers 709 are equidistantly connected to the inner walls of both sides of the axle frame 711 through bearings.

The output ends of the two hydraulic cylinders 712 are fixedly connected to limit pressure plates 708. A plurality of groups of limit spring rods 714 are provided on the top inner wall of the limit frame 705. A contact round rod 713 is fixedly connected to the bottom of each group of limit spring rods 714. The top inner wall of the limit frame 705 located between each adjacent two contact round rods 713 is fixedly connected to a limit airbag 710.

[0043] Specifically, when performing stamping operations on non-ferrous metals, after the non-ferrous metals pass through the limit frame 705, the hydraulic cylinder 712 is adjusted to drive the limit pressure plate 708 to squeeze the two ends of the non-ferrous metal. At the same time, the upper limit airbag 710 and the contact round rod 713 elastically limit the upper surface of the non-ferrous metal. After being limited at both ends and the top, the non-ferrous metal is prevented from being dislocated or partially bounced during the stamping process, thereby improving the accuracy of the stamping position.

[0044] It should be noted that the limiting airbag 710 and the contact rod 713 are staggered to avoid excessive squeezing of the limiting airbag 710 and the upper surface of the non-ferrous metal, which may cause difficulty in advancing the non-ferrous metal. At the same time, the elastic limitation reduces the vibration damage to the non-ferrous metal during the stamping process. During the stamping process of the non-ferrous metal, if the angle of the non-ferrous metal needs to be adjusted, the forward and reverse motor 706 is started to drive the limiting frame 705 to deflect, and the dial 702 monitors the deflection angle in real time, thereby improving the functionality of the stamping die.
