Description

Oblique punching forming progressive die

Technical Field

The utility model belongs to the technical field of stamping forming, concretely relates to oblique punching shaping modulus of continuity.

Background

The progressive die is characterized in that a press machine adopts a strip-shaped stamping raw material in a stamping stroke, a plurality of different stations on a pair of dies simultaneously complete a cold stamping die of a plurality of stamping processes, and the material strip moves once at a fixed distance when the dies complete stamping until a product is completed. For a bent steel plate with the thickness of more than 2.0mm, when the requirements of flat plate punching and bent back bevel punching are required, the forming requirement is difficult to achieve by adopting the existing progressive die on the premise of not increasing the cost, and the forming quality can not be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model provides a dash shaping modulus of continuity to one side.

The purpose of the utility model is realized through the following technical scheme:

oblique punching forming progressive die, including the last mould and the lower mould of mutually supporting, be provided with the oblique punching subassembly in going up the mould, the oblique punching subassembly is including fixed insert and slider, the spout has been seted up on the fixed insert, be provided with the contained angle between spout and the horizontal plane, the slider set up in the spout, and slide in the spout, be connected with the drift perpendicularly on the slider, the oblique punching subassembly still includes one and takes off the flitch and goes into son, the punching press end of drift extends to and takes off in the flitch goes into son.

Preferably, the upper die comprises an upper die base, an upper backing plate, a fixing plate, a stripper backing plate and a stripper in sequence from top to bottom, and the fixing insert is arranged between the upper backing plate and the fixing plate in a penetrating manner.

Preferably, the stripper plate insert is disposed in the stripper plate.

Preferably, the lower die comprises a lower die base and a concave die plate, a product to be obliquely punched is arranged on the concave die plate, an ejector rod is further arranged in the lower die, and the ejector rod penetrates through the concave die plate.

Preferably, the to-be-obliquely-punched single product is a bent piece with an included angle, and the to-be-obliquely-punched hole is formed in an inclined plane of the bent piece.

Preferably, the included angle between the sliding groove and the horizontal plane is equivalent to the included angle of the product to be punched.

The beneficial effects of the utility model are embodied in: through the cooperation of the fixed insert and the inclined plane slide block, the inclined plane of the bent piece can be punched well, the punching process is reduced, and the machining efficiency is improved.

FIG. 2: the structure of the utility model is schematically shown.

Detailed Description

The technical solution of the present invention is specifically described below with reference to the following examples. The utility model discloses a dash shaping modulus of continuity to one side, figure 1 shows the utility model discloses a treat the dash board to one side, treat dash 6 including straight board section and with straight board section is the swash plate section that the contained angle set up, and the contained angle between two sections is generally less than 90. The hole to be punched 61 is placed on the ramp section.

Referring to fig. 2, the continuous inclined punch forming die for the plate to be obliquely punched comprises an upper die and a lower die which are matched with each other, and an inclined punch assembly is arranged in the upper die. The upper die sequentially comprises an upper die base 1, an upper backing plate 2, a fixing plate 3, a stripper plate backing plate and a stripper plate 4 from top to bottom. An elastic element is arranged between the stripper plate backing plate and the stripper plate 4, and the elastic element is a rectangular spring or a nitrogen spring and is used for assisting die sinking. The lower die sequentially comprises a lower die base, a concave die plate base plate and a concave die plate 5 from bottom to top. The piece to be obliquely punched is placed on the concave die plate 5 during punching. Still be provided with the ejector beam in the lower mould, the ejector beam wears to locate treat that the oblique punching plate direction extends in the die block.

The inclined punching assembly comprises a fixed insert 7 and a movable slide block 71 arranged on the fixed insert 7, and the fixed insert 7 is arranged between the upper backing plate 2 and the fixed plate 3 in a penetrating manner. The fixed insert 7 is provided with a sliding groove which forms an included angle with the horizontal plane, and the sliding block 71 is arranged in the sliding groove and can slide in the sliding groove. The included angle that sets up between spout and the horizontal plane is equivalent with treating the punching press product included angle. The slide block 71 is vertically connected with a punch 8, and the punching end of the punch 8 extends into the stripper plate insert 9. The stripper plate insert 9 is arranged in the stripper plate 4.

The following brief description of the blanking process of the utility model:

and placing the piece to be punched obliquely 6 on the concave template 5, moving the punch downwards to drive the upper die holder, the upper padding plate, the fixing plate and the fixing insert 7 to move downwards simultaneously, moving the slide block downwards in the cavity of the fixing insert 7 along the inclined chute, closing the die, and punching the piece to be punched obliquely 6 by the punch to finish punching. The punch drives the upper die to open the die, the elastic element bounces off the stripper plate backing plate and the stripper plate, the upper die base, the upper backing plate and the fixing plate drive the sliding block 71 to slide in the fixing insert 7, and meanwhile, the punch 8 moves upwards along with the upper die to drop a punched product. The dies are opened and closed to complete the punching and blanking of the product, and in order to ensure the precision of the punching hole and protect the punch 8, the punching end of the punch 8 needs to be ensured to be always arranged in the stripper plate insert 9 in the die opening process.

Use the utility model discloses an oblique punching subassembly integrates it with the modulus of continuity, can reduce the stamping process that needs the flat board to punch a hole and punch a hole on the inclined plane simultaneously, great saving the punching press cost, the practicality is strong.

The utility model has a plurality of specific implementation modes. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
