Description

A kind of hook moulding Special-purpose combined die

Technical field

The utility model relates to the sheet metal mould technical field, especially a kind of hook moulding Special-purpose combined die.

Background technology

At present, all can use crooked hook on large-scale steel structure members, steel tower, light pole, high lamp stand, automotive frame and automobile container, the technique of the crooked hook of traditional mode of production is: adopt manually line, then bend to the size required on drawing in bending to 60 ° left and right on bender on forcing press.This traditional processing technology need to adopt two molds to complete on two equipment, and production efficiency is lower, unstable product quality, and precision is poor, so far, there is no the mould that a kind of energy has been concentrated hook twice bending operation.

Summary of the invention

The purpose of this utility model is improved for the deficiencies in the prior art exactly, and a kind of hook moulding Special-purpose combined die is provided, and to realize completing pre-bending and the moulding of hook on a mold, thereby realizes reducing costs and enhancing productivity.

Concrete scheme of the present utility model is: a kind of hook moulding Special-purpose combined die includes upper die and lower die; It is characterized in that: described counterdie inside is provided with endoporus, in endoporus, slides middle mould is housed, and the bullet ejection device is equipped with in middle mould bottom, and the rectangular hierarchic structure in right side, bottom of middle mould forms the secondary flex area between this right angle hierarchic structure and counterdie; The bottom of patrix and the top of middle mould are the ，Qi angle of inclination, inclined-plane tilted towards upper right side and are α, and the base angle in patrix left side is fillet; The top of described counterdie is positioned at the endoporus left side and is provided with protruding moulding block, the lateral surface of moulding block is the inclined-plane tilted towards upper right side, its inclination angle is also α, the moulding block is consistent with horizontal clearance S and thickness of workpiece between patrix by the perpendicular end surface of middle mould one side, on the inclined-plane of moulding block, striker plate is housed, form flex area first between moulding block, patrix and middle mould, during bending first, the residing extreme position in patrix base angle, left side is positioned at moulding block drift angle below.

The bottom of patrix described in the utility model and middle mould top and moulding block outside inclined-plane three's inclined angle alpha is 30 °～45 °.

Destroyed for fear of surface quality in the hook BENDING PROCESS, realize there is no impression after the hook bending, the utility model has half slot at the drift angle place of moulding block, rolls in half slot the rod that rolls is housed.

Consider cost-saving and convenient processing, the upper die and lower die in the utility model all adopt the inlaid type structure.

The utility model is provided with flex area and secondary flex area first, can on same set of mould, complete prebuckling and two operations of final molding of hook, need not adopt two molds respectively in bender and the enterprising line bend operation of forcing press, equipment investment and human cost have been saved, use simpler, safeguard conveniently, to enterprise, brought huge economic benefit.

The accompanying drawing explanation

Fig. 1 is main cutaway view of the present utility model;

Fig. 2 is the work schematic diagram that the utility model carries out bending first;

Fig. 3 is the work schematic diagram that the utility model carries out the secondary bending.

In figure: the 1-counterdie, the 2-striker plate, 3-moulding block, the 4-half slot, 5-rolls excellent, the 6-patrix, 7-is flex area first, mould in 8-, 9-right angle hierarchic structure, 10-secondary flex area, 11-endoporus, 12-bullet ejection device, 13-blank, 14-semi-finished product, 15-hook finished product.

The specific embodiment

Referring to Fig. 1, the utility model includes patrix 6 and counterdie 1, and patrix 6 and counterdie 1 all adopt the inlaid type structure.Counterdie 1 inside is provided with endoporus 11, in endoporus 11, slides middle mould 8 is housed, and middle mould 8 bottoms are equipped with and are played ejection device 12, and the rectangular hierarchic structure 9 in the right side, bottom of middle mould 8 forms secondary flex area 10 between this right angle hierarchic structure 9 and counterdie 1.The top of the bottom of patrix 6 and middle mould 8 is the ，Qi angle of inclination, inclined-plane tilted towards upper right side and is α, and the base angle in patrix 6 left sides is fillet.The top of counterdie 1 is positioned at endoporus 11 left sides and is provided with protruding moulding block 3, moulding block 3 forms an integral body with counterdie 1, the lateral surface of moulding block 3 is the inclined-plane tilted towards upper right side, its inclination angle is also α, and moulding block 3 is consistent with horizontal clearance S and thickness of workpiece between patrix 6 by the perpendicular end surface of middle mould 8 one sides.Striker plate 2 is housed on the inclined-plane of moulding block 3, forms flex area 7 first between moulding block 3, patrix 6 and middle mould 8, during bending first, the residing extreme position in base angle, left side of patrix 6 is positioned at the drift angle below of moulding block 3.
