Embodiment Construction

[0037] For a better understanding of the present invention, below in conjunction with the attached Figure 2-9 And embodiment the present invention is described further.

[0038] The U-shaped elastic knot cold-press forming method and device adopts a press to apply pressure to a pressing mold and press the elastic knot once to form it.

[0039] Such as Figure 2-7 As shown, the pressing mold is pressed by a press and mainly includes an upper mold 3 and a lower mold 4; the upper mold 3 is a portal structure, and the middle is an arch-shaped concave portion; The arch-shaped recesses of the upper mold are matched with each other; the upper mold 3 is formed by inserting the upper mold bottom plate 5 and a plurality of upper mold ribs 6, and the lower mold 4 is formed by inserting the lower mold bottom plate 10 and a plurality of lower mold ribs 14; It includes a positioning plate 17 arranged on one side of the upper and lower molds 3 and 4, and the height of the positioning plat...

Abstract

The invention relates to a method and a device for forming a U-shaped elastic knot by cold pressing. The method and the device are characterized in that the elastic knot is formed by adopting one-time pressing of a pressing die; the pressing die is produced by using a pressing machine and mainly comprises an upper die and a lower die; the upper die is of a gate-type structure; an arched concave part is arranged in the middle of the upper die; a protruded part in the middle of the lower die is mutually matched with the arched concave part of the upper die; the top end of the upper die is formed by splicing an upper die base plate with a plurality of upper die rib plates; and the bottom end of the lower die is formed by splicing a lower die base plate with a plurality of lower die rib plates. According to the method and the device, the U-shaped elastic knot can be formed by pressing at one time without rework; and the method and the device have the advantages of high efficiency, batch production, favorable forming quality and high forming identical degree of products.

Description

technical field [0001] The invention relates to a metal processing method and device, in particular to a method and device for one-time cold-press forming of U-shaped elastic structural parts. Background technique [0002] The elastic knot is a U-shaped device with a certain degree of elasticity, which acts as a connection buffer. The U-shaped elastic knot is shaped like figure 1 As shown, the storage tank of the liquefied gas carrier is an important equipment for waterway transportation of liquefied gas. Since the waterway transportation fluctuates greatly during the river and sea transportation, in order to reduce the instantaneous strong impact of the liquefied gas in the storage tank on the tank wall when it fluctuates, usually A swash bulkhead is arranged in the ship storage tank perpendicular to the direction of the ship, and the swash bulkhead 15 is connected with the inner wall 2 of the tank by an elastic knot 1 to play the role of shock absorption and buffering. ...
