Technical Field
[0001] The utility model relates to the technical field of punching and forging equipment, in particular to an upper and lower punching and forging die. Background Art
[0002] Hardware is the most common metal parts and components. Hardware is needed in various products and fields to complete the assembly and processing of products. Figure 1-2 The above is a hardware accessory used in a laptop computer, specifically used in the rotating shaft part of the display screen and the host computer, used to accommodate the rotating shaft and part of the electronic wire or other electronic components. The hardware has a cylinder 01 and a baffle 02 located inside the cylinder 01. The traditional processing technology of the hardware is welding. Specifically, the cylinder 01 is processed into a cylinder 01 having a shape that meets the requirements by stamping a tubular workpiece. The tubular profile workpiece can also be processed on a CNC machine tool to be processed into a cylinder 01 that meets the required shape, and then the cylinder 01 is welded. 1 is welded to the inside of the cylinder 01 by welding the baffle 02. This processing method is simple and common. Most manufacturers currently use the above processing method. However, due to the small internal space of the cylinder, the welding effect is not very good during the welding process of the baffle. It is easy to cause leakage, cold welding, incomplete welding, etc., thereby affecting the performance of the hardware. After long-term use, the baffle is very likely to fall off, causing the laptop to malfunction. For hardware manufacturers and computer manufacturers, the above-mentioned failure will bring great economic losses. Utility Model Content

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0024] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
[0025] The utility model embodiment provides an upper and lower forging die, which is used to perform forging processing on the hardware mentioned in the background technology. The baffle 02 and the cylinder 01 can be integrally formed by processing with the die, thereby improving the firmness of the hardware and effectively preventing the baffle 02 from falling off the cylinder 01. Figure 3-6 As shown, an upper and lower punching and forging die provided by an embodiment of the utility model is provided with a first die 10, an intermediate die base 32 and a second die 20 from top to bottom, wherein the first die 10 includes a first die base 11, on which a first die head 12 of a predetermined shape is mounted; the second die 20 is arranged opposite to the first die 10, and includes a second die base 21, on which a second die head 22 corresponding to the first die head 12 is mounted; the intermediate die base 32 is provided with a forming hole 31 for the first die head 12 and the second die head 20 to be punched therein along two side directions, and the intermediate die base 32 is provided with a thickness of a predetermined size, so that after the first die head 12 and the second die head 22 are punched into the forming hole 31 along two side directions, there is a gap of a predetermined size between the first die head 12 and the second die head 22.
[0026] During the punching and forging process, the blank is placed in the forming hole 31. It can be imagined that the second die head 22 of the second die 20 is located at the lower side of the forming hole 31 and at the lower opening position of the forming hole 31. When the blank is placed in the forming hole 31, the second die head 22 supports the blank to prevent the blank from being moved out of the forming hole 31. When the first die 10 and the second die 20 are driven by the power device to punch toward the middle die base 32, the first die head 12 and the second die head 22 punch into the forming hole 31 along the two sides of the forming hole 31, thereby forging the blank so that the blank is formed along the inner wall of the forming hole 31. At the same time, because the middle die base 32 has the function of making the first die head 12 and the second die head 22 have a predetermined size gap The thickness of the gap can form an intermediate between the first die 12 and the second die 22 during the forging process of the blank, thereby constituting the baffle 02 inside the cylinder 01. It can be imagined that the inner hole size of the forming hole 31 is larger than the size of the first die 12 and the second die 22, that is, after the first die 12 and the second die 22 are punched into the forming hole 31, there is a space between the outer walls of the first die 12 and the second die 22 and the inner wall of the forming hole 31, and the space enables the blank to be formed during the forging, thereby forming a cylinder 01 with the same shape as the inner wall of the forming hole 31, and the intermediate between the first die 12 and the second die 22 forms the baffle 02 inside the cylinder 01.
[0027] The present mold can be used to integrally mold the cylinder 01 and the baffle 02, thereby avoiding the need to weld the cylinder 01 and the baffle 02. The cylinder 01 and the baffle 02 can be tightly and reliably connected to each other, and the baffle 02 will not fall off inside the cylinder 01, thereby ensuring that the hardware has high performance.
[0028] It is worth noting that the mold can be installed on a molding machine, and the first mold 10 and the second mold 20 are driven to punch toward the middle mold base 32 by the stamping components on the molding machine. At the same time, the middle mold base 32 is fixedly installed on the molding machine. In order to ensure the reliability and smoothness of the stamping action of the first mold 10 and the second mold 20, guide members are provided between the middle mold base 32 and the first mold 10 and between the middle mold base 32 and the second mold 20. In the present embodiment, the guide member can be a guide rod (not shown in the figure), one end of which is fixedly installed on the middle mold base 32, and the other end is slidably connected with the first mold 10 and the second mold 20, thereby guiding the stamping of the first mold 10 and the second mold 20.
[0029] In this embodiment, the second die 20 also includes a limit member 23, which includes two limit members 23, which are respectively arranged on both sides of the second die head 22 and detachably installed on the second die base 21. The limit members 23 are used to limit the size of the second die head 22 punching into the forming hole 31.
[0030] The limiter 23 is used to limit the stamping stroke of the second die 20. At the same time, it can limit the depth of the second die head 22 punching into the forming hole 31. By replacing the limiter 23 with different thickness sizes, the depth of the second die head 22 punching into the forming hole 31 can be adjusted, and then the spacing distance between the second die head 22 and the first die head 12 can be adjusted to meet the processing requirements of the baffle 02 with different thickness sizes.
[0031] like Figure 6 The middle mold base 32 includes a middle mold base 32 seat, on which an inlay 33 is detachably arranged, and the forming hole 31 is arranged on the inlay 33. The forming holes 31 of different shapes can be arranged on different inlays 33, so that the inlays 33 can be used to process hardware of different shapes.
[0032] In this embodiment, the installation method of the inlay 33 and the middle mold base 32 is that the inlay 33 is detachably installed in the installation hole 34 by forming an installation hole 34 on the middle mold base 32, and the inlay 33 can be detachably connected with the middle mold base 32 by means of clamping, bolting, etc. At the same time, in order to avoid position error of the inlay 33 during installation, a limit surface 331 is set on the outer surface of the inlay 33, and a corresponding surface 341 matched with the limit surface 331 is formed on the inner wall of the installation hole 34. In this embodiment, the inlay 33 is cylindrical, and the limit surface 331 is a plane formed on the circumferential surface. Correspondingly, the corresponding surface 341 is also a plane, so that the inlay 33 can be limited to rotate in the installation hole 34, and the inlay 33 can be limited and positioned to ensure the installation accuracy of the inlay 33.
[0033] For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structure and principle disclosed by the utility model, and all of these changes and deformations belong to the protection scope of the utility model.
