Hydraulic upturning mechanism

Abstract

The invention provides a hydraulic upturning mechanism which comprises a jack-up nitrogen cylinder, an insert mounting plate, guide pillars, guide sleeves, a mounting body, a turn-up insert, a lower mould insert and an upper material pressing insert, wherein the jack-up nitrogen cylinder is fixed on the mounting body; the mounting body is fixed on a lower mould; the guide pillars are fixed on the upper surface of the mounting body; the insert mounting plate is fixed above the top of the jack-up nitrogen cylinder; guide sleeves are fixed on the insert mounting plate, sleeve the guide pillars, and can slide up and down along the guide pillars correspondingly; the turn-up insert is fixed on the insert mounting plate; the upper mould insert is provided with a concave cutting edge which is matched with the turn-up insert; a concave opening which is matched with the cutting edge of the upper mould insert is formed in the upper material pressing insert. The hydraulic upturning mechanism has the advantages that a guide device is additionally arranged to ensure precision; the effect of side turning resistance on a work part which has higher side force can be better; the size tolerance requirement can be met; the structure is simple; the cost for mould manufacture can be greatly reduced.

Description

technical field [0001] The invention relates to the field of molds, in particular to a hydraulic upturning mechanism. Background technique [0002] In the process of stamping die processing, there are often local areas that need to be turned up and down. In this case, the relevant technical personnel will generally use a set of dies to complete the process if the process permits, that is, increase One pressing core is used to complete the upturning. In many cases, a part has relatively few upturned areas. If one or several places are upturned, adding a downpressing core will greatly increase the cost of mold processing. And in the process of turning up in operation, often due to the large lateral force, the precision of turning up is not accurate enough to cause the unqualified situation of the workpiece to occur. Contents of the invention [0003] In order to solve the above technical problems, the technical solution adopted by the present invention is to provide a hydra...

Problems solved by technology

[0002] In the process of stamping die processing, there are often local areas that need to be turned up and down. In this case, the relevant technical personnel will generally use a set of dies to complete the process if the process permits, that is, increase A lower pressing core is used to complete the upturning. In many cases, a part has relatively few upturned areas. If one or several places are turned up, adding a lower pressing core will greatly increase the cost of mold processing.

Moreover, in the process of turning up the operation, due to the large lateral force, the precision of turning up is not accurate enough to cause the unqualified situation of the workpiece to appear.
