Plate-spring forming quenching hardened die and application thereof

Abstract

The invention relates to a plate-spring forming quenching hardened die and an application thereof. The plate-spring forming quenching hardened die is characterized in that standardized and serialized quenching hardened dies are adopted in the plate-spring quenching process, and the corresponding quenching hardened die with the quenching curvature closest to that of a plate spring is selected according to the quenching curvature of the plate spring. The quenching hardened dies used in the plate-spring quenching process is normalized and serialized, and all the quenching hardened dies are prepared only by one time, so that the total number of the quenching hardened dies is greatly reduced, the technical design is simplified, the cost of the quenching hardened dies is saved, the management of the quenching hardened dies is facilitated, the quenching hardened die selecting adjustment time is shortened, the production efficiency is improved, the stability of the quality of a product is guaranteed, and the reject loss caused by misuse of the quenching hardened dies is avoided.

Description

technical field [0001] The invention relates to a leaf spring forming quenching die and its application, in particular to a quenching die used in the leaf spring quenching process and its application. Background technique [0002] Leaf springs are non-standard parts used in automobiles, with different lengths, widths, thicknesses, number of sheets, and arc heights. Due to different design calculation methods, lack of unified design technical specifications, etc., the quenching curvature radii of leaf springs (referred to as leaf springs) are different. It can be said that the quenching curvature radii of different reeds of different products are different. However, according to the functional characteristics and statistical data of leaf springs in automobiles, it is not difficult to find that the quenching curvature radius of various leaf springs has a strong concentration. The radius of curvature of the range is quite rare, and the range with a higher distribution frequenc...

Problems solved by technology

Due to the large number of hard molds and complex product names and numbers, it is difficult to be clear and sure in the management process. When the production workshop selects hard molds, the operator needs to repeatedly select and check the hard mold names and numbers according to the production plan and process data. And the size, very inconvenient, often takes several hours, and the cases of waste products caused by choosing the wrong die also happen from time to time

When the product is quenched and hard molded, it is easy to make mistakes, and it is necessary to find out from several sets of molds

Since each reed hard mold is unique, during the process of installing and adjusting the mold, the operator is also cautious, strives for perfection, and is afraid of missing the slightest bit, which is very time-consuming

At present, the company has more than 200 kinds of products. According to the traditional method, more than 2,000 pieces of quenching samples or hard molds will be made. With the continuous increase of products, the number of molds will also increase. During the period, there will be repeated production of hard molds.
