technical field

The utility model relates to a combined mold in the technical field of mechanical manufacturing, in particular to a combined mold for simultaneously cutting a round head and punching end pad holes for a rolled leaf spring.

Background technique

In the production process of the spring steel plate, in order to avoid the abnormal sound of the steel plate assembly between the installed plates, and the heat generated by the friction without the spacer between the plates will reduce the fatigue life of the assembly, it is necessary to adjust the spring after rolling. The steel plate has a straight length, a round end or a flat shape for trimming, and a process hole is added at the end of the rolled sheet to install a circular plastic elastic gasket. At present, in most leaf spring manufacturing industries, two sets of equipment and two sets of tooling are used for the process of cutting the round head and end pad hole of the rolled spring sheet respectively. First, the round head is processed, and then the end pad hole is punched. Processing, and different molds are used for cutting the round head and punching end pad hole, that is, when cutting the round head, use the cutting head mold, and when punching the end pad hole, use the punching end pad hole mold. Therefore, a lot of mold equipment is required, a lot of labor is required for production and processing, the processing is cumbersome, the processing cost is high, and quality problems are prone to occur.

A combination mold, the top of the upper template is provided with a mold handle, the bottom is equipped with a middle mold body and one side of the middle mold body is equipped with a guide sleeve, the bottom of the middle mold body is equipped with an upper blade seat; the lower bottom plate is installed with a guide column And corresponding to the guide sleeve; the middle mold body and the upper blade seat are provided with a cavity, and a combined spring is installed in the cavity, the lower end of the combined spring is equipped with a spring seat, the bottom of the spring seat is connected with a push rod, and the lower end of the push rod is equipped with a There is a pressing sleeve with a through hole in the center, a cavity is provided in the ejector rod, and a punch is installed in the cavity. The lower end of the punch corresponds to the through hole of the pressing sleeve, and the punch is fixed on the middle mold body by screws. One side of the binder sleeve is provided with an upper blade, and the upper blade is fixed and installed under the upper mold body through bolts; the lower base plate is fixed with a lower blade seat, and a composite lower blade is fixedly installed on the blade seat, and the composite lower blade is provided with a punch The corresponding punching hole, the lower blade seat and the lower bottom plate are provided with a blanking hole corresponding to the punching hole; one side of the lower blade seat is fixed with a positioning frame, and one side of the positioning frame is fixed with a side baffle, and the positioning frame An elongated groove is provided, and a longitudinal positioning seat is arranged in the elongated groove, and the longitudinal positioning seat is connected with the threaded plate under the elongated groove by bolts.

The utility model has the advantage that by installing the punch, the upper blade and the compound lower blade on the mold at the same time, the process of punching the end pad hole and cutting the round head can be completed on the rolled leaf spring at the same time, which reduces the number of molds and It takes less time to replace the mold during the operation, which improves the production efficiency of the pad hole of the punching end of the leaf spring and the round cutting head, makes the product quality more stable, and reduces the production cost.
