Pressure spring manufacturing aid

Abstract

The invention discloses a pressure spring manufacturing aid. The pressure spring manufacturing aid comprises a support and an extrusion plate, wherein the extrusion plate is slidably connected with the support; the support comprises a supporting plate and supporting legs; the supporting legs are positioned on the bottom of the supporting plate; a fixing plate is arranged at the left end of the supporting plate; a supporting rod and a guiding rod are arranged on the fixing plate; the guiding rod is positioned above the supporting rod; an arc-shaped groove is formed in the fixing plate; a chute is formed in the supporting plate; the extrusion plate is provided with a guiding hole which is matched with the guiding rod and a through hole which is matched with the supporting rod; the extrusion plate is also provided with an arc-shaped groove; a hydraulic cylinder is arranged at the right end of the supporting plate and is provided with a piston rod, a pressure gauge, an oil inlet tube and an oil outlet tube; the piston rod is detachably connected with the extrusion plate; and the length of the supporting rod is smaller than that of the guiding rod. By the pressure spring manufacturing aid, the shortcomings that two ends of a pressure spring which is machined by the existing small equipment are straight ends and are required to be machined by an auxiliary device further, but equipment for machining hooks in markets is high in cost, complex in structure and low in safety factor are overcome.

Description

technical field [0001] The invention relates to the field of compression springs, in particular to an auxiliary device for producing compression springs. Background technique [0002] The compression spring is a helical spring that bears the pressure. Because it can bear the pressure, the two ends can be open or closed, or wound or ground. The cross-section of the material it uses is mostly circular, and it is also useful for rectangular and multi-strand steel coils. The spring has equal pitch and variable pitch. The shape of the compression spring is: cylindrical, conical, convex and concave, as well as a small amount of non-circular and even various tail end variants. All products are available. It needs to be shaped according to the design, etc. There is a certain gap between the rings of the compression spring. When the spring is subjected to an external load, the spring shrinks and deforms to store deformation energy. [0003] Usually, for large enterprises to purchase...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the defects of high cost, complicated structure and low safety factor of the equipment for processing hooks on the market, which are aimed at the fact that the two ends of the compression spring processed by the existing small equipment are straight ends and need to be further processed by auxiliary devices. An auxiliary device for making a compression spring, which has the characteristics of simple operation, low cost and high safety factor for processing the hooks at both ends of the compression spring
