The utility model discloses mainly through a knock pin mechanism with bottom plate mound piece in pressing the regional shaping of the material face several convex closure shapes, realize drawing the location behind the finished piece jack-up with these several convex closure shapes to guarantee automatic conveying's position accuracy, realize the finished piece jack-up through the spring, utilize the shaping back shape to realize the finished piece through the knock pin and hold up the back location.
Description
Technical Field
The utility model belongs to the technical field of draw the shaping, concretely relates to finished piece holds up positioning mechanism after drawing the shaping.
Background
After the drawing process is completed, the workpiece is often required to be jacked up to be higher than the molding surface of the material pressing ring so that the workpiece can be grabbed by a mechanical arm. After the workpiece is jacked up, the stability of the workpiece needs to be ensured, so that the accuracy of automatic transmission is ensured.
Jacking devices are conventionally implemented using a jacking block assembly, as shown in fig. 4 and 5, and the jacking device generally realizes positioning of a jacked drawing piece in two ways, namely, embedding a magnet on the jacking block (mostly used in the case that the profile of the jacking area has no shape), and positioning by using a shape on the jacking block (the shape of a drawing rib is required on the jacking block). Structural design is complicated loaded down with trivial details relatively more above, in addition, because the cooperation relation between each part requires higher and needs the cylinder drive, processes and is equipped with certain degree of difficulty, and the cost is quite high simultaneously.
Disclosure of Invention
The utility model provides a finished piece hold up positioning mechanism after drawing the shaping solves the finished piece of drawing and fixes a position the problem after the jack-up, compares with traditional means, the utility model discloses the structure is simple and easy, and design, processing assembly are easier, and the location effect is more effective, and the cost is very low.
The utility model discloses a following technical scheme combines the attached drawing:
a supporting and positioning mechanism for a drawn and molded workpiece comprises a base plate 5, a material pressing ring 3, a heading block 2, an upper die 4 and a knock-pin mechanism, wherein the heading block 2 is fixed on the base plate 5, the material pressing ring 3 is installed on a lower die in a floating mode, the knock-pin mechanism is installed on the material pressing ring, the position of the knock-pin mechanism corresponds to the position of the heading block 2, and after the die is closed, the knock-pin mechanism is locally molded into a convex hull shape in a material pressing surface area. The method is mainly characterized in that a plurality of convex hull shapes are formed in a material pressing surface area through a knock-out pin mechanism and a bottom plate upsetting block, and the convex hull shapes are used for realizing the positioning of a drawn workpiece after jacking, so that the position accuracy of automatic transmission is ensured.
The ejector pin mechanism comprises an ejector pin 1 and a spring, the ejector pin 1 is installed on the material pressing ring through the spring, and the top of the ejector pin is a convex hull type curved surface. The spring is used for jacking the workpiece, and the jacking pin is used for realizing the positioning of the workpiece after being supported by the molded shape.
The utility model has the advantages that: the structure is novel, the ejection and the positioning are simultaneously realized by using a simple ejector pin mechanism, and the requirements of the workpiece on supporting and positioning are simultaneously met by skillfully using a very simple forming mechanism; the occupied space is small, the structural arrangement is simple, and the processing and the assembly are easy; and forming by utilizing the top end shape of the ejector pin, and positioning by utilizing the top end shape of the ejector pin.

Detailed Description
The technical scheme of the utility model is described in detail with the attached drawings as follows:
a supporting and positioning mechanism for a drawn and molded workpiece comprises a base plate 5, a material pressing ring 3, a heading block 2, an upper die 4 and a knock-pin mechanism, wherein the heading block 2 is fixed on the base plate 5, the material pressing ring 3 is installed on a lower die in a floating mode, the knock-pin mechanism is installed on the material pressing ring, the position of the knock-pin mechanism corresponds to the position of the heading block 2, and after the die is closed, the knock-pin mechanism is locally molded into a convex hull shape in a material pressing surface area.
The ejector pin mechanism comprises an ejector pin 1 and a spring, the ejector pin 1 is installed on the material pressing ring through the spring, and the top of the ejector pin is a convex hull type curved surface.
The utility model discloses a theory of operation does:
the plate enters the working procedure and stays at the jacking height position of the jacking pin (as shown in figure 1); in the closing process of the die, the upper die presses the ejector pin down to the height of the pressing surface, the ejector pin is in contact with the lower die upsetting block about 5mm before the die reaches a lower dead point, upward forming is completed under the reaction force of the upsetting block, and the pressing surface area is in a convex hull shape (as shown in figure 2); after the die is stretched, the upper die is opened, the material pressing ring is lifted, the female die and the lower die are separated after the material pressing ring reaches the top dead center, the ejector pin continues to be lifted under the action of the spring, the workpiece is ejected to a manipulator workpiece picking position, and meanwhile, the ejector pin and the convex hull of the workpiece are matched with each other to realize positioning after the workpiece is ejected (as shown in fig. 3).
