Embodiment Construction

[0032] refer to Figure 1 to Figure 3 The embodiment of a stamping and stretching automatic production device and its control method of the present invention will be further described.

[0033] For ease of description, if spatially relative terms such as "upper", "lower", "left", and "right" are used in the embodiments, they are used to describe the relative relationship between one element or feature shown in the figure and another element or feature Relationship. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other ...

Abstract

The invention discloses a stamping stretching full-automatic production device and a control method thereof, and aims to provide the stamping stretching full-automatic production device which is highin stability, simple in structure and high in practicability. The stamping stretching full-automatic production device is characterized in that a first buffer oil path comprises a first buffer valve and a first on-off valve, a valve cavity of the first buffer valve is internally provided with an inner valve core, the inner valve core includes a mesa portion and a planar portion, the mesa portion is located in an oil return cavity, the planar portion is located in a re-pressing cavity, a mesa area of the mesa portion is less than the planar portion, the inner valve core is provided with a plurality of through holes communicating with the oil return cavity and the re-pressing cavity, a reset spring is arranged in the re-pressing cavity, and when a workpiece reaches a predetermined stretchingvalue, the first buffer valve is gradually closed by gradually closing the first on-off valve, and when the pressure of the valve core in the first buffer valve is gradually reduced from the pressureof a hydraulic pump until the first on-off valve is closed, the first buffer valve carries out the acting force of the reset spring, so that the plugging effect on the first buffer valve is formed; and the stamping stretching full-automatic production device is suitable for the technical field of machining equipment.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, more specifically, it relates to a stamping and stretching automatic production device and a control method thereof. Background technique [0002] Stretch forming is a stamping method that uses a die to form a flat blank into an open hollow part. As one of the main stamping processes, stretching is widely used. Thin-walled parts of cylindrical, rectangular, stepped, spherical, conical, parabolic and other irregular shapes can be made by stretching process, and parts with more complex shapes can be manufactured if combined with other stamping forming processes . [0003] At present, the stamping and stretching full-automatic production device on the market includes a piston processing system, a transmission system and a composition. The piston processing system consists of a punch press, a first hydraulic press, a second hydraulic press and a third hydraulic press. The tr...
