Spring stretching and correcting device

Abstract

The invention discloses a spring stretching and correcting device. The spring stretching and correcting device comprises an operation table, wherein the upper end of the operation table is successively fixedly connected with a fixing vertical frame and a fixing cross frame from left to right; a correcting mechanism is arranged on the inner side of the fixing vertical frame; a detecting mechanism is arranged on the inner side of the fixing cross frame; a dropping groove of which the position corresponds to the fixing cross frame is formed in the operation table in a penetrating manner; a baffleis arranged in the dropping groove and is slidably connected with the inner wall of the dropping groove; the lower end of the operation table is fixedly connected with a cleaning box of which the position corresponds to that of the dropping groove; the lower end of the cleaning box is fixedly connected with a liquid draining tube; a cleaning mechanism is arranged in the cleaning box; a drawing groove is formed in a side wall of the cleaning box in a penetrating manner; and the inside of the drawing groove is slidably connected with a collecting net frame. A spring can be rapidly stretched andcorrected, stretching while heating is realized, the correcting effect is good, after the spring is corrected, the performance of the spring can be tested, and the spring can be cleaned.

Description

technical field [0001] The invention relates to the technical field of spring shaping, in particular to a spring stretch correction device. Background technique [0002] A spring is a mechanical part that uses elasticity to work. It deforms under the action of an external force and returns to its original shape after the external force is removed. It is generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] In the process of spring production, some springs will be deformed. It is a pity to throw away unqualified spring products. Therefore, it is necessary to correct the axial direction of the spring, and the spring will also be deformed after long-term use. The spring must be corrected. For correction, the existing methods generally use tools and equipment to continuously apply force to the out-of-tolerance part of the spring to f...

Problems solved by technology

[0003] In the process of spring production, some springs will be deformed. It is a pity to throw away unqualified spring products. Therefore, it is necessary to correct the axial direction of the spring, and the spring will also be deformed after long-term use. The spring must be corrected. For correction, the existing methods generally use tools and equipment to continuously apply force to the out-of-tolerance part of the spring to fix it within the tolerance range, stretch the spring to be corrected to the length of its plastic deformation, and carry out the process after putting the spring into the furnace For heat treatment, the equipment needs to be removed after being released from the furnace. The process is more complicated and the operation is more cumbersome. Therefore, it is now necessary to design a spring tension correction device. Therefore, it is now necessary to design a spring tension correction device.
