In order to achieve the purpose, the embodiment of the utility model provides a drawing die of automobile panel, this drawing die of automobile panel include terrace die, die and pressure flitch, pressure flitch is located between terrace die and the die, pressure flitch with the side of die forms the edging district, the edging district is provided with first draw bead, a serial communication port, the edging district is provided with the draw fence, the draw fence sets up and is keeping away from one side of the first draw bead of die, the draw fence is kept away from the opposite side of die is provided with the second draw bead.

Optionally, the blank holders on two sides of the female die are respectively and symmetrically provided with a first draw bead, a draw fence and a second draw bead.

Optionally, the draw bar and the draw bead are protruded towards the direction of the female die, the protrusion height of the draw sill structure is smaller than that of the draw bead, and the protrusion height of the second draw bead is smaller than that of the first draw bead.

Optionally, the die rail and the pressure plate rail are respectively formed in a step shape with corresponding positions.

The embodiment of the utility model provides a beneficial effect that technical scheme brought includes at least:

the embodiment of the utility model provides an in, through be provided with on the blank pressing district of at least one side and be used for preventing that the material of pressing in the blank pressing district from producing warping drawing fence to further prevent the warpage of pressing the material in the blank pressing district on the basis of draw bead, thereby shorten the manufacturing cycle of part and reduce the work load of later stage assembly part, and then reduce manufacturing cost.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic structural diagram of a drawing die for an automobile panel, provided by an embodiment of the present invention.

The reference numerals include:

1. a male die; 2. a female die; 3. a material pressing plate; 4. a drawing fence; 5. a first draw bead; 6. a second draw bead.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "secured to" another element, it can be directly connected to the other element or intervening elements may also be present.

In the present invention, unless otherwise specified, the terms of orientation such as "up, down, left, and right" used generally refer to up, down, left, and right as shown in fig. 1. "inner and outer" refer to the inner and outer portions of a particular contour. "distal and proximal" refer to distal and proximal relative to a component.

As shown in fig. 1, an embodiment of the utility model provides a drawing die of automobile panel, this drawing die of automobile panel include terrace die 1, die 2 and press the flitch 3, press the flitch 3 to be located between terrace die 1 and the die 2, press the side formation blank pressing district of flitch 3 and die 2. The female die 2 is arranged on an upper die base of the press machine, and the upper die base is fixedly arranged on a sliding block of the press machine. The male die 1 and the pressure plate 3 are arranged on a lower die holder of the press machine, and the lower die holder is fixed on a workbench of the press machine. Under the structure, the male die 1 and the pressure plate 3 can slide relatively in the vertical direction, and the ejector rod on the workbench of the press machine penetrates through the lower die holder and abuts against the pressure plate 3, so that the blank holder force in the drawing process is provided. When the plate is drawn, the female die 2 and the pressure plate 3 drive the plate and the male die 1 to be matched, so that the plate is punched.

Usually, one or more draw beads 5 are arranged in at least one side of the edge pressing zone of the drawing die to provide drawing resistance and control the flow of the pressing material. However, when the sheet material is thick, the draw beads cannot provide sufficient drawing resistance, so that the buckling phenomenon still exists after the material pressing forming. For this purpose, a draw bar 4 and a second draw bead 6 are provided.

The edge pressing area is provided with a first draw bead 5, the edge pressing area is provided with a draw fence 4, the draw fence 4 is arranged on one side of the first draw bead 5 far away from the female die 2, and the other side of the draw fence 4 far away from the female die 2 is provided with a second draw bead 6.

Optionally, the first draw bead 5, the draw bar 4 and the second draw bead 6 are respectively and symmetrically arranged on the blank holder areas on two sides of the female die 2.

Optionally, the draw bar 4 and the first draw bead 5 are protruded towards the direction of the die 2, the protruding height of the draw bar 4 is smaller than that of the first draw bead 5, and the protruding height of the second draw bead 6 is smaller than that of the first draw bead 5.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
