Description

Quick-release spring bolt for tubular pile die assembly

Technical Field

The utility model relates to a tubular pile processing field, in particular to tubular pile is quick detach formula spring bolt for compound die.

Background

The spring mold-closing bolt is widely applied to mold-closing manufacturing of concrete products such as pipe piles, telegraph poles, drain pipes and the like. Traditional spring compound die bolt all includes subassemblies such as screw rod, spring, upper spring seat, lower spring seat, and it is when the assembly, utilizes the spacing arch of screw rod lower part axial to pass through little jump ring with lower spring seat and is connected the cooperation, realizes down the axial spacing of spring seat. The disadvantages of this structure are: the assembly can not be disassembled, if one component is damaged, the whole assembly needs to be scrapped, so that the cost of an enterprise is increased, and the waste of resources is also caused.

Therefore, in view of the above phenomena, a spring clamping bolt is proposed in patent CN102672822A, which includes a jaw bolt, an upper spring washer, a spring, a lower spring bushing, a base, a nut, and a nut base, and is innovative in that: the rod body section of the closing bolt is provided with an axial limiting part, and the inner surface of the lower spring bushing is provided with a lower spring bushing limiting bulge matched with the axial limiting part; the lower spring bushing limiting bulge is connected with the lower spring bushing through a detachable connecting structure. The lower spring bushing limiting bulge is matched with the closing bolt in an axial limiting mode, and the lower spring bushing is axially limited. When parts such as the spring fracture or the close bolt abrasion are damaged due to long-term use, the lower spring bushing limiting bulge is removed through the detachable structure, the lower spring bushing, the spring, the upper spring gasket and the close bolt can be detached, the damaged parts are replaced correspondingly, the whole scrapping is avoided, and the resources and the use cost are saved. Meanwhile, the detachable connecting structure has a compact structure and lower manufacturing cost.

The above-mentioned clamp bolt still has certain defect in the course of using: because the die assembly bolt is applied to die assembly of the tubular pile, the tubular pile can be centrifugally formed after die assembly, in the process, part of mortar inevitably flows out from a gap between an upper die and a lower die of the tubular pile, and part of the mortar is adhered to the surface of the die assembly bolt, so that part of the mortar is inevitably solidified on the outer surface of the die assembly bolt after long-term use, and under the condition, when a spring or other parts of the die assembly bolt are damaged or damaged and the like, and maintenance or replacement is required, the part is blocked due to the solidified mortar, for example, a limiting part cannot be smoothly pulled out, so that the closed bolt cannot be smoothly separated from a lower spring bushing, the spring cannot be smoothly taken down, namely the spring cannot be replaced independently, and the whole body needs to be replaced, it is very troublesome.
