Problems solved by technology

In this way, the entire production line needs a lot of automation equipment, which requires a large area and high production costs.
[0008] 2. Tapping after folding is used, and the precision of the product is poor
Especially for products with high strength requirements, it is necessary to germinate first and then tap, and bending after germinating will cause the position deviation of the germinating hole, which will affect the quality of the entire product

Embodiment Construction

[0028] Such as figure 1 , the back panel of the LED display is a typical metal sheet metal part with side edges, with folded edges on all four sides (always referred to as side edge 1 in this patent), and there are many hooks on the bottom surface and side edge 1, Process details such as long-distance undulations, positioning holes, protrusions, engraved explanatory text, chamfering, etc., including the threaded hole 2 related to the present invention. Moreover, these process details require high precision, and there must be no deviation, otherwise it will affect the assembly and service life of the display.

[0029] The invention includes a processing device, especially a structure for realizing tapping in a continuous die.

[0030] Such as figure 2 , image 3 Structural embodiment of the above structure: a vertically downward lead screw 4 is fixed on the upper die 3 through a fixing device, and a tap fixing device 6 is fixed on the lower die 5. The connection relationshi...

Abstract

The invention provides a progressive die equipment and method for machining a sheet metal component with a threaded hole on a lateral-face edge belt, belonging to the field of metal machining. The equipment comprises an upper die and a lower die; the upper die and the lower die are mutually matched; and a plurality of punching machining positions are arranged on the upper die and the lower die. The progressive die equipment is characterized by being provided with a screw tap position; a screw rod is arranged on the upper die at the screw tap position; a screw tap fixing device is arranged on the lower die; the screw tap fixing device comprises a rotary mechanism engaged with the screw rod; and the rotary mechanism is connected with a screw tap. The progressive die equipment and the method provided by the invention have the advantages of high production efficiency and high precision; the one-step formation in a progressive die punching process can be realized; and the process can be simplified, the number of the equipment is reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to continuous die processing of sheet metal parts, which belongs to the field of metal processing, and in particular to continuous die processing of sheet metal parts with folded side edges and threaded holes on the side faces through a continuous die stamping process. Background technique [0002] The processing technology of thin sheet metal parts is mostly stamping. The continuous die is a means of automatic production of stamping parts. Production. [0003] The design of the continuous mold takes into account the specific structure and requirements of the product, such as the shape, internal positioning holes, deburring, engraving and other manufacturing requirements, all of which can be manufactured using the continuous mold. [0004] However, in some special products, there are obstacles in continuous die processing, such as the backplane of LED displays. The backplane of the LED display is the support device for the panel...
