Upturning structure assembly based on hydraulic mechanism

Abstract

The invention provides an upturning structure assembly based on a hydraulic mechanism. The upturning structure assembly comprises a hydraulic driving device, guide columns, guide sleeves, a turnup insert, an abutting block, an insert installation seat and a hydraulic cylinder. The abutting block is fixedly connected with an upper die body, the hydraulic driving device is matched with the abutting block, a through hole is respectively arranged at four corners of the insert installation seat, each through hole is provided with a guide sleeve in matching mode, each guide sleeve is provided with a guide column in matching mode, the guide columns are fixedly connected onto the installation seat, a through hole is arranged at the center on the lower end face of the installation seat, a round disc flange is matched on the upper end face of the installation seat, the hydraulic cylinder is fixedly connected onto the installation seat through the flange, the turnup insert is fixedly connected at the center position of the upper end face of the insert installation seat, and the installation seat is fixedly connected onto a lower die body. The upturning structure assembly is simple, compact and reasonable in structure and has the advantages of being low in cost, high in product pass percent and wide in application range.

Description

[0001] technical field [0002] The invention relates to the field of molds, in particular to an upturning structure based on a hydraulic mechanism. Background technique [0003] In the structural design of stamping dies, it is often necessary to add a lower core or a complete set of dies due to local shaping or upper flanging areas. In general, if there are a large number of shaping areas in the mold of large parts, there are usually two design ideas. One is to complete it together with other processes (forward punching and repairing, etc.), and the whole set of molds needs to press the core up and down. , to achieve the purpose of forward punching and upper shaping. In this case, it is a method to save the process when the number of processes is not allowed; another method is to provide only one set for the upper shaping when the number of processes is allowed. Mold, that is, there is a lower pressing core in the mold, that is, a simple upper shaping mold. However, in many...

Problems solved by technology

However, in many cases, there are relatively few areas where a part has upturning, upturning or upturning holes. Therefore, adding a whole lower core only for the upturning or upturning of a small area will greatly increase the mold cost. However, in most cases, people will directly install the shaping flanging insert or the punch mounting seat on the piston rod of the hydraulic cylinder. When the force is large, it may lead to insufficient precision, poor quality of the working area and unqualified parts
