Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses an accurate stamping die of auto metal accessories, including cope match-plate pattern 1 and lower bolster 2, cope match-plate pattern 1 is located lower bolster 2 directly over, and 2 upsides of lower bolster are fixed with four rather than vertically guide post 16, and four guide post 16 are located the four corners department of 2 upsides of lower bolster respectively, and four guide post 16 all wear to locate cope match-plate pattern 1. The lower side of the upper template 1 is detachably provided with a punching column 3 vertical to the upper template, and the upper side of the lower template 2 is provided with a punching hole 4 corresponding to the punching column 3. The lower side of the upper template 1 is elastically provided with a pressing plate 5 parallel to the upper template, the punching column 3 penetrates through the pressing plate 5, and the pressing plate 5 is used for pressing 5 materials. During punching press processing, panel is placed in 2 upsides of cope match-plate pattern, through driving 1 decline of cope match-plate pattern, drives the 5 decline of pressure strip and 5 materials of pressure strip when 1 decline of cope match-plate pattern, and the while punching press post 3 is driven and is descended, and 3 therefore punching press panels of punching press post make its trompil. When the punching column 3 is worn, the punching precision can be maintained by replacing the punching column 3, and the processing cost is saved.

Referring to fig. 1 and 2, a plurality of limiting rods 12 are arranged on the upper side of the upper template 1 in a penetrating manner, preferably four limiting rods 12 are arranged in the embodiment, and the four limiting rods 12 are uniformly distributed. Four gag lever post 12 all with cope match-plate pattern 1 threaded connection, the top of four gag lever post 12 all is fixed with hand wheel 15 coaxially. The stopper rod 12 limits a minimum gap between the upper and lower templates 1 and 2. Gag lever post 12 removes along with cope match-plate pattern 1 is close to lower bolster 2, when gag lever post 12 bottom butt on lower bolster 2, has restricted the possibility that cope match-plate pattern 1 and punching press post 3 continue the gliding to make the stamping process more accurate, rotate gag lever post 12, because gag lever post 12 and 1 threaded connection of cope match-plate pattern, thereby gag lever post 12 slides for 1 relative of cope match-plate pattern, so that adapt to the panel of different thickness.

Referring to fig. 1 and 2, four sleeves 13 corresponding to the limiting rods 12 are vertically fixed on the upper side of the pressing plate 5, the four limiting rods 12 penetrate through the four sleeves 13, and the limiting rods 12 penetrate through the pressing plate 5. The periphery of each limiting rod 12 is sleeved with a compression spring 14, one end of each compression spring 14 is fixed to the top end of the corresponding sleeve 13, and the other end of each compression spring is fixed to the lower side of the corresponding upper template 1. The pressure strip 5 moves close to the lower template 2 along with the upper template 1, and the pressure strip 5 preferentially leans on the panel on the lower template 2, and continues to descend along with the upper template 1, so that the compression spring 14 continues to be compressed, and meanwhile, the elasticity of the compression spring 14 enables the pressure strip 5 to tightly abut on the panel, thereby facilitating the fixation of the panel. Along with the continuation decline of cope match-plate pattern 1, love abusing and pass 5 butts at 2 upsides of lower bolster for the pole, punching press is accomplished to panel to punching press post 3 simultaneously to this completion punching press operation.

Referring to fig. 1 and 2, an adjusting assembly for driving the punching column 3 to adjust the height is arranged between the upper template 1 and the lower template 2, the abutting block 6 is arranged in the punching hole 4 in a vertically sliding manner, and a sliding part for driving the abutting block 6 to vertically slide is arranged between the lower template 2 and the abutting block 6. The adjustment assembly comprises a connection plate 7, a threaded rod 8 and a plurality of guide rods 9. The top end of the punching column 3 penetrates through the upper template 1, and the connecting plate 7 is horizontally fixed at the top end of the punching column 3. Threaded rod 8 and a plurality of guide bar 9 are all worn to locate connecting plate 7 perpendicularly and threaded rod 8 and connecting plate 7 threaded connection, and the bottom of threaded rod 8 is rotated and is installed the upside at cope match-plate pattern 1, and the upside at cope match-plate pattern 1 is all fixed to the bottom of a plurality of guide bar 9. The cross section of the top end of the threaded rod 8 is arranged in a square shape, a handle 10 is detachably inserted into the top end of the threaded rod 8, and the handle 10 is arranged in an L shape. Rotating handle 10 and driving threaded rod 8 and rotating, because threaded rod 8 and connecting plate 7 threaded connection to along with the rotation of threaded rod 8, connecting plate 7 and punching press post 3 slide for cope match-plate pattern 1, with this length that conveniently adjusts punching press post 3 and stretch to 1 downside of cope match-plate pattern, adjust 6 upsides of butt joint piece for 2 upside distances of lower bolster through the slider simultaneously. When the bottom end of the stamping rod is abutted against the upper side of the abutting block 6, the slotting operation on the plate is completed, and the grooves with various different depths are conveniently machined by adjusting the heights of the stamping rod and the abutting block 6 simultaneously, so that the machining cost is saved.

Referring to fig. 1 and 2, the hole wall at the bottom end of the punching hole 4 is provided with a thread, the sliding part is a stud 11, the stud 11 is arranged in the punching hole 4 in a penetrating manner, and the stud 11 is in threaded connection with the lower template 2 through the punching hole 4. The stud 11 is located on the lower side of the abutting block 6, a rotating groove (not shown in the figure) which is convenient for rotating the stud 11 is formed in the bottom end of the stud 11, and the top end of the stud 11 abuts against the lower side of the abutting block 6. The height of the abutting block 6 can be conveniently adjusted by rotating the stud 11, and the stud 11 is separated from the punching hole 4 by rotating, so that the plate can be conveniently processed.

The implementation principle of the embodiment is as follows:

punching press man-hour, panel is placed at 2 upsides of lower bolster, through driving 1 decline of cope match-plate pattern, drive 5 declines and 5 materials of pressure strip when cope match-plate pattern 1 descends, simultaneously the punching press post 3 is driven and is descended, punching press post 3 makes its indent form groove consequently, adjust the length that punching press post 3 stretches to 1 downside of cope match-plate pattern through adjusting part, the distance of the upside distance lower bolster 2 upsides of butt joint piece 6 is adjusted through the slider simultaneously, with this convenient groove of the different degree of depth of processing on panel, need not to change the mould and can accomplish the processing in multiple degree of depth groove, through demolising butt joint piece 6, make things convenient for the trompil operation to panel, after punching press post 3 wearing and tearing, it can maintain the precision of punching press post 3 to change punching press post 3, thereby maintain the precision of punching press processing, and the processingquality is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
