The invention discloses an arc clamping and pressing die comprising a lower die seat and an upper die seat. The lower die seat comprises a base. One side of the base is provided with a first groove. The lower side of the first groove is provided with a second groove. The upper side of the base is provided with a third groove. The third groove extends from the upper side of the base to the first groove. The upper side of the base is provided with a limiting groove. An insertion block is arranged in the limiting groove. The upper side of the base is provided with two circular-truncated-cone limiting grooves in diagonal distribution. The upper die seat comprises a stamping seat. One side of the stamping seat is provided with a limiting boss. By the adoption of the arc clamping and pressing die, when an arc is pressed, it is not needed to speed lot of time on location of a sheet metal part, and through the first groove and the insertion bock, the sheet metal part can be rapidly and accurately located; after the sheet metal part is fixed to a certain position, a stamping machine is utilized to drive the upper die seat to conduct forming stamping; and in this way, it can be effectively guaranteed that the produced sheet metal parts are identical in specification, and errors are lowered to the lowest.
Description
technical field [0001] The invention relates to a mold, in particular to a clamping arc mold. Background technique [0002] With the development of science and technology, the production process of sheet metal arcs is becoming more and more popular, and the technology is relatively mature. Usually, the production methods of sheet metal arcs mainly include the following methods: one-time molding of special molds and multiple pressing moldings. Either method is only suitable for bending the sheet metal into an arc shape as a whole. However, it is relatively difficult to bend the upper part of the sheet metal into a circular arc, such as Figure 7 As shown, the bending of this method in the prior art mainly has the following disadvantages: 1. The bending point of the sheet metal part needs to be confirmed many times during bending, which will waste a lot of time in determining the position; 2. 1. The error of the sheet metal parts after bending is relatively large, which canno...
