Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] refer to figure 1 , a supercharged electric servo deep drawing pad 60, including a supercharged electric cylinder 6, a top crown 7, a ejector rod 8 and a blank holder 9, at least one supercharged electric cylinder 6 is fixed to the press body 1 by bolts At the bottom, the piston rod 601 of the supercharged electric cylinder 6 is connected to the bottom of the top crown 7. The number and distribution position of the supercharged electric cylinder 6 can be adjusted according to the drawing process. One end of the ejector rod 8 is connected to the top crown 7, and the other One end is connected with the blank holder 9, and the connection mode is bolt connection or welding.

[0025] refer to figure 2 and image 3 , the boosted electric cylinder 6 is an AC servo electric cylinder that integrates the functions of the electric cylinder and the booster cylinder. T...

Abstract

Disclosed is a supercharged electric servo deep-drawing cushion. At least one supercharged electric cylinder is fixed on the bottom of a body of a press; pistons of the supercharged electric cylinders are connected with the bottom of a top crown; one end of a material ejecting rod is connected with the top crown; the other end of the material ejecting rod is connected with a blank holder; and each supercharged electric cylinder is an alternating-current servo electric cylinder which has functions of an electric cylinder and functions of a supercharged cylinder. The supercharged electric servo deep-drawing cushion has a deep-drawing action and a material ejecting action; after the supercharged electric servo deep-drawing cushion is combined with an upper mold or a lower mold of the press, the optional blank holder force required for tensile deformation of workpieces can be realized, and mechanical energy is transformed into electric energy in a deep-drawing process. The supercharged electric servo deep-drawing cushion is simple in structure and low in failure rate; the supercharged electric cylinders has the functions of the electric cylinder and the functions of the supercharged cylinders, so that the working load of the supercharged electric cylinders is greatly reduced; and the supercharged electric servo deep-drawing cushion which is integrated in design is compact in structure.

Description

technical field [0001] The invention relates to a drawing pad device, in particular to a pressurized electric servo drawing pad. Background technique [0002] The deep drawing pad is an important auxiliary device in the plastic processing of the sheet metal. Its function is to press the sheet metal before deep drawing, and to press the edge during the forming process. It can accompany the upper mold or the lower mold for deep drawing movement to Prevent wrinkling or cracking caused by excessive flow of material during sheet forming, and improve the drawing quality of the workpiece. [0003] At present, there are two kinds of drawing mats commonly used in the market: pure air drawing mat and CNC hydraulic drawing mat. The working medium of pure air drawing mat is gas. With the increase of the stretching stroke, the blank-holding force fluctuates greatly, which makes the blank-holding force of the workpiece unstable. Due to the existence of the cylinder, it needs to occupy a ...
