Problems solved by technology

After the blank is stamped and formed, the sheet metal needs to be stamped and trimmed due to the requirement of machining accuracy. The positioning plate on the pressing die is used to assist in positioning the sheet metal, but the positioning plate on the traditional pressing die is inconvenient to install, and Displacement is easy to occur during the stamping process, resulting in pressing deformation

Embodiment Construction

[0013] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] Such as Figure 1~3 The metal plate pressing mold shown includes a lower mold 1 and an upper mold 2 matched with the lower mold. The lower mold includes a lower mold base plate 11 , a molding positioning assembly fixed on the lower mold base plate 11 and two sets of lower mold tables 12 . The two groups of lower mold tables 12 are oppositely arranged, and a positioning chute 13 is left between the two groups of lower mold tables 12 . A positioning plate 14 for assisting the positioning of the sheet metal is clamped on the lower mold table 12, and one side end surface of the positioning plate 14 is in the positioning chute 13, and a first arc-shaped groove 15 is opened on the side end surface of the positioning plate 14, and the lower The end surface of the mold table 12 is provided with a second arc-shaped groove 16 conne...

Abstract

The invention relates to the field of punching dies, in particular to a pressing die of a metal plate. The pressing die comprises a lower die and an upper die matched with the lower die, the lower die comprises a lower die baseplate, a die press positioning component and two lower die platforms, the die press positioning component and the lower die platforms are fixed on the lower die baseplate, the lower die platforms are arranged oppositely, a positioning sliding groove is reserved between the lower die platforms, a positioning plate for assisting in positioning the metal plate is connected on the lower die platforms in a clamped manner, and the end face on one side of the positioning plate is positioned in the positioning sliding groove; the die press positioning component comprises a positioning base arranged at a notch of the positioning sliding groove, a lower wedge-shaped block movably arranged on the positioning base and a locking block connected with the lower wedge-shaped block, two upper die platforms respectively correspond to the lower die platforms, and an upper wedge-shaped block corresponds to the lower wedge-shaped block in a bevel matching manner. The positioning plate in the pressing die can adopt a convenient mounting mode, and then a self-locking structure is formed during punching through the die press positioning component to ensure stability, so that convenience is brought to adjustment and replacement of the positioning plate.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a pressing die for sheet metal. Background technique [0002] Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] With the rapid development of the economy, automobiles have become the main means of transportation for people, and what follows is the vigorous development of the automobile industry. Due to the limitation of the use environment, auto parts need to have high manufacturing precision and assembly precision. Therefore, the stam...
