Embodiment 1

[0038] Through the analysis of the technical problems in the background technology, it can be known, such as Figure 5 As shown, the wrong riveting situation is mainly caused by the misplacement of the small hardware 4 in the hole of the large hardware, because the large hardware 4 cannot be put into the small hole.

[0039] For this, as Image 6 with Figure 7 As shown, the lower template 1 of the stamping equipment is provided with a height-limiting block 2 that is matched with the belt installation hardware 4 (that is, the type of the height-limiting block 2 corresponds to the type of the hardware 4 one by one), preferably, The height limiting block 2 is cylindrical, and the lower template 1 is provided with a cylindrical groove for accommodating the height limiting block 2, and when the height limiting block 2 is placed in the groove When inside, the upper end surface of the height limiting block 2 is flush with the upper side of the lower formwork 1 . The upper end sur...

Embodiment 2

[0049] Generally speaking, the function of the hardware 4 is the thread and height. The thread is related to the inner diameter of the hardware 4, and the outer diameter of the hardware 4 generally has little effect on the function of the product 3 and can be adjusted. Therefore, it can be adjusted according to the actual situation in the design. If it is necessary to adjust the outer diameter of the hardware, the outer diameter of the short hardware 4 is designed to be large.

[0050] Product 3 structure optimization hardware 4 outer diameter size can be realized in most cases, but there are also special cases, such as when the hardware 4 outer diameter and height have functional effects at the same time, the outer diameter cannot be adjusted casually.

[0051] According to the stamping experience of iron parts, the opening size of the lower die hole of the metal riveting die is determined by the root diameter of the hardware, and if the outer diameter of the hardware 4 in pro...

Embodiment 3

[0056] The hardware 4 installed on the lower formwork 1 is named successively according to the order of the diameter of the end portion 42 from small to large, as the first type of hardware, the second type of hardware ... the Nth type of hardware.

[0057] As a specific implementation, there are three types of hardware on the lower formwork 1 described in this embodiment, and they are the first type of hardware and the second type of hardware according to the order of the diameter of the end portion 42 from small to large. and the third category of hardware.

[0058] The lower template 1 is provided with through holes 11 corresponding to the first type of hardware and height limiting blocks 2 corresponding to the second type of hardware and the third type of hardware respectively.

[0059] All the other structures are the same as in Embodiment 1.

Abstract

The invention discloses an improved design method for easy wrong riveting of hardware of a server sheet metal part, and relates to the technical field of sheet metal part pressing riveting processing.Specifically, a lower template of stamping equipment is provided with a height limiting block matched with hardware to be installed, and when the height limiting block is installed on the lower template, the upper end face of the height limiting block is flush with the upper side face of the lower template. The upper end face of the height limiting block is provided with a plug-in hole extendingdownwards. The sum of the lengths of the end parts of the hardware and a transition connecting part is sequentially increased according to the diameter of the end parts from large to small, and when the hardware is placed in the plug-in hole in a staggered mode, the hardware is in a jacked state. According to the improved design method, the problem that different types of hardware are prone to being riveted in a wrong mode in the aspect of mass production processing can be solved, improvement can be carried out through the scheme as long as mass production processing is carried out through a mold, 100% fool-proof can be achieved through structural design optimization and mold improvement, and the method is particularly suitable for server products with moderate yield.

Description

technical field [0001] The invention relates to the technical field of riveting processing of sheet metal parts, in particular to an improved design method for error-prone riveting of server sheet metal parts. Background technique [0002] There are many pieces of iron and gold products that need riveting hardware, such as the studs for locking the main board of the machine base, the I-shaped hardware for the upper cover to be inserted into the base, the positioning pin hardware for the upper cover to be inserted into the rear window, and so on. [0003] In order to facilitate the understanding of this program, a brief description of the riveting processing method is now given. Such as figure 1 with figure 2 As shown, the so-called pressure riveting first needs to place the product to be processed on the lower template of the pressure riveting equipment, and then put the hardware into the through hole that has been pre-processed on the product. Correspondingly, the lower...
