Abstract
The utility model discloses a drawing mold with an upper mold equipped with a swaging loose piece. The drawing mold comprises an upper mold base (1), a swaging loose piece (4) is arranged at a large-radian bending part of the upper mold base (1) in a sliding manner, the upper mold base (1) is provided with a cylinder acted on the swaging loose piece (4), and the swaging loose piece (4) is arranged on the upper mold base (1) in a sliding manner through a side pin (7). The cylinder is a nitrogen cylinder (6). According to the drawing mold, through precompression molding on the loose piece of the upper mold, the product can be prevented from wrinkling caused by uneven flowing materials due to large product shape fluctuation, later-period debugging time of the mold can be greatly shortened, and the production period of the mold can be shortened, and the production cost and the efficiency of the mold can be lowered and reduced.
Description
Technical field
The utility model relates to a kind of drawing die.
Background technology
In the Auto body panel die design manufacture process, some covering is because the demand of outward appearance or the deficiency of locus need to be made the larger situation of crooked radian (a few tee beam), for example large bending curvature technique need to be realized in front longitudinal extension board part position, and large bending curvature causes easily drawing that the stream material is inhomogeneous produces gauffer and break when crooked position draws.Solve gauffer and the common scheme of breaking be on-the-spot bead size and the lathe pressure size adjusted with the flow velocity of control material, too fast wrinkling easily, break easily slowly.Since can only by the scene do not stop to adjust to reach wrinkling and break between critical point, the defective of the method is apparent, the later stage repeatedly adjust production cycle and the cost increased undoubtedly mould.
The utility model content
Technical problem to be solved in the utility model provides a kind of large bending curvature when drawing at crooked position draws that Shi Buhui produces gauffer and the drawing die of the patrix band binder loose piece that breaks.
In order to solve the problems of the technologies described above, the drawing die of the patrix band binder loose piece that the utility model provides, comprise upper bolster, sliding at the large bending curvature position of described upper bolster is provided with the binder loose piece, is provided with the cylinder that acts on described binder loose piece at described upper bolster.
Described binder loose piece is slidingly mounted on the described upper bolster by the side pin.
Described cylinder is nitrogen cylinder.
Adopt the drawing die of the patrix band binder loose piece of technique scheme, upper bolster is descending with the lathe top shoe in the course of work, and the binder loose piece provides pressure and punch part profile to kill precompressed by nitrogen cylinder; Upper bolster continues descending contact with blank holder and with the plate compacting; Upper bolster and blank holder are simultaneously descending subsequently, contact with punch residue profile to begin to draw, until bottom dead centre is finished drawing operation.Lathe is up, the upper bolster return, and pneumatic jack is with blank holder jack-up, and blank holder ejects product, and the workman takes product away, so far finishes a product drawing process.Because large bending curvature position is designed to movable part, the first pre-press-bending of realization is drawn again, prevents from causing greatly stream to expect that the inhomogeneous product that makes is wrinkling because shape of product rises and falls; Solved for wrinkling easily in drawing process such as (especially crooked radian is larger, and sidewall is more vertical, the product that the degree of depth is large) parts such as several tee beams the problem of breaking.
In sum, the utility model prevents from causing greatly the inhomogeneous product that makes of stream material wrinkling because shape of product rises and falls by patrix loose piece pre-molding, thereby significantly reduces the die debugging time in later stage, shortens the mould production cycle, reduces mould production cost and efficient.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, be provided with binder loose piece 4 at the large bending curvature position of upper bolster 1, binder loose piece 4 is slidingly mounted on the upper bolster 1 by side pin 7, is provided with the nitrogen cylinder 6 that acts on binder loose piece 4 at upper bolster 1.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, drawing the larger product patrix of a few tee beam crooked radians increases binder loose piece 4, and first precompressed is to improve draw forming.Binder loose piece 4 is installed on the upper bolster 1 by the side pin.Upper bolster 1 is descending with the lathe top shoe in the course of work, and binder loose piece 4 provides pressure and punch 5 part profiles to kill precompressed by nitrogen cylinder 6; Upper bolster 1 continues descending contact with blank holder 2 and with the plate compacting; Upper bolster 1 is simultaneously descending with blank holder 2 subsequently, contacts with punch 5 residue profiles to begin to draw, until bottom dead centre is finished drawing operation.Lathe is up, and upper bolster 1 return, pneumatic jack be blank holder 2 jack-up, and blank holder 2 ejects product, and the workman takes product away, so far finishes a product drawing process.
Large bending curvature draws Shi Buhui generation gauffer and breaks at crooked position after improving.
