Abstract

The utility model discloses a novel traceless bending lower mold and belongs to the technical field of bending and machining of medium-thickness steel plates. The novel traceless bending lower mold overcomes the defect that because when a workpiece to be bent is machined through a transfer bending lower mold in the prior art, the size consistency and the overall appearance quality of the formed workpiece are poor. The novel traceless bending lower mold mainly comprises a lower mold body, roller column mounting bases are arranged on the two sides of the lower mold body respectively, roller columns are arranged on the roller column mounting bases, and roller column baffles are arranged at the two ends of each roller column mounting base. A hoisting threaded hole is formed in the lower mold body. The lower mold body is made of T8 steel, the roller column mounting bases are made of 42CrMo, and the roller columns are made of Cr12MoV. The novel traceless bending lower mold is mainly used for bending and machining the medium-thickness steel plates.

Description

Novel seamless bending lower die
Technical field
The utility model belongs to medium plate Bending Processing technical field, specifically, relates in particular to a kind of Novel seamless bending lower die.
Background technology
The engineering machinery such as loading machine, excavator medium plate bending part, adopts common bending lower die to add man-hour, has 2 hidden danger:
1. bending impression approximately has 0.3 millimeters deep, impact spray paint after overall appearance quality;
2. in Forging Process, the suffered force of sliding friction in bending workpieces both sides is variant, and after bending workpieces is shaped, dimensional uniformity is poor.
Summary of the invention
In order to solve in prior art, transmit dimensional uniformity and the second-rate defect of overall appearance after bending lower die processing bending workpieces easily causes it to be shaped, the utility model provides a kind of Novel seamless bending lower die.
The utility model is achieved through the following technical solutions:
A Novel seamless bending lower die, comprises lower mould body, and lower mould body both sides are respectively equipped with roller mount pad, and roller mount pad is provided with roller, and roller mount pad two ends are respectively equipped with roller baffle plate.
Lower mould body is provided with lifting screwed hole.
Described lower mould body adopts T8 steel, roller mount pad to adopt 42CrMo, roller to adopt Cr12MoV to be made.
Compared with prior art, the beneficial effects of the utility model are:
The force of rolling friction that roller is subject to bending workpieces is minimum, avoids producing bending impression, has guaranteed the dimensional uniformity after bending workpieces moulding;
The utility model is simple in structure, and lower mould body, roller mount pad and roller carry out separately machining and heat treatment, low cost of manufacture, and the utility model maintenance cost is low, maintenance cycle is short, only needs to change or repair roller.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is use state reference map of the present utility model.
Roller baffle plate in the drawings, 1; 2, lifting screwed hole; 3, lower mould body; 4, roller; 5, roller mount pad; 6, entablature; 7, bending upper die; 8, bending workpieces; 9, lower fuselage.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A Novel seamless bending lower die, comprises lower mould body 3, and lower mould body 3 is provided with lifting screwed hole 2, and lower mould body 3 both sides are respectively equipped with roller mount pad 5, and roller mount pad 5 is provided with roller 4, and roller mount pad 5 two ends are respectively equipped with roller baffle plate 1; Described lower mould body 3, roller mount pad 5, roller 4 adopt respectively T8 steel, 42CrMo, Cr12MoV to be made.
When mounted, roller mount pad 5 is bolted on lower mould body 3 the utility model.
The utility model in use, be used in conjunction with bending upper die 7, bending upper die 7 is installed on the entablature 6 of numerical control bender, and lower mould body 3 is installed on the lower fuselage 9 of numerical control bender, during work, bending workpieces 8 is placed on the utility model, starts numerical control bender, bending upper die 7 moves down, roller 4 is in the interior rotation of roller mount pad 5, now bending workpieces 8 is subject to less force of rolling friction, avoids producing bending impression, has guaranteed the dimensional uniformity after bending workpieces 8 moulding.
