Abstract
The invention discloses a flexure bending process outside angle iron. The process comprises the steps: 1, transversely cutting a slit along the middle part at one edge of an angle iron raw material by a high temperature fire lance for initial treatment, while performing no treatment on the other edge; 2, bending the angle iron raw material initially treated by a bending die installed on a hydraulic press; and 3, obtaining a finished flexure angle iron product. The process provided by the invention has the advantages that the bending process which is originally completed manually is replaced by machine, so that the bending effect is good, the product quality is high, the labor force is saved, and the cost is saved.
Description
Technical field
The present invention relates to angle steel bending technical field, relate in particular to the outer lateral flexure system bending process of a kind of angle steel.
Background technology
In steel tower corner iron is produced, usually relate to the technology of angle steel bending, the present method that the outer lateral flexure of angle steel is bent all is to be wherein boiled one crack, one side of angle steel with the high temperature firelock earlier, the workman makes firmly pincers or iron staff that angle steel is bent then, the method of this artificial bending angle steel not only will expend workman's muscle power in a large number, and often bending degree is not accurate manually to bend the angle steel that obtains, and bending excessively makes the whole fracture of angle steel easily, cause product rejection, cause the wasting of resources.
Summary of the invention
The technical problem to be solved in the present invention is that a kind of promptly accurate and outer lateral flexure system bending process of labour-saving angle steel is provided.
For addressing the above problem the technical scheme that the present invention takes be:
The outer lateral flexure system bending process of a kind of angle steel, described technology comprises step:
(1) wherein going out a crack with the high temperature firelock along middle crosscut does preliminary treatment on one side with the angle steel raw material, another side is left intact, and ruptures when angle steel system is curved fully in the crack that crosscut goes out, and separate on the both sides, crack, make angle steel can not produce the main force in the curved engineering of system, system is curved very easy;
(2) using the outer lateral flexure system bending mould that is installed on the hydraulic press to carry out outer lateral flexure system the angle steel raw material of preliminary treatment bends, described system bending mould comprises upper die and lower die two parts, patrix is made up of the curved drift of hydraulic press connecting plate and system, counterdie is made up of two carriages of base plate and placement angle steel, carriage in the described system bending mould is two T shape carriages staggered relatively that four V shape iron pieces are formed, two V shape iron pieces are formed a T shape carriage, T shape tray chamber has the slit to be used to place angle steel one end, angle steel of two common picking-ups of T shape carriage;
(3) obtain finished product outside sweep angle steel.
The invention has the advantages that, with the curved work of the outer lateral flexure system of artificial angle steel originally, changing machinery into through the present invention finishes, saved workman's amount of labour greatly, and the curved production efficiency height of the mould system of employing, the outer lateral flexure angle steel bending that obtains is more accurate, and product is not easy to take place to cause owing to the bending error phenomenon of product rejection in the production process.
Description of drawings
Fig. 1 is the angle steel raw material schematic diagram after the high temperature firelock is handled.
Fig. 2 is outer lateral flexure system bending mould schematic diagram.
Fig. 3 is the crooked angle steel schematic diagram of finished product that this technology obtains.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
The outer lateral flexure system bending process of a kind of angle steel, as shown in Figure 1 angle steel raw material 1 is wherein gone out a crack 2 with the high temperature firelock along middle crosscut on one side, do preliminary treatment, with the angle steel of preliminary treatment former 1, to carry out outer lateral flexure system curved with being installed in outer lateral flexure system bending mould on the hydraulic press, ruptures when angle steel system is curved fully in the crack 2 that crosscut goes out, and separate on the both sides, crack, make angle steel can not produce resistance in the curved engineering of system, system is curved very easy.
Make bending mould as shown in Figure 2 and comprise upper die and lower die two parts, patrix is made up of the curved drift 4 of hydraulic press connecting plate 3 and system, counterdie is made up of two carriages of base plate 6 and placement angle steel, carriage in the described system bending mould is two T shape carriages staggered relatively that four V shape iron pieces 5 are formed, two V shape iron pieces 5 are formed a T shape carriage, T shape tray chamber has the slit to be used to place angle steel one end, angle steel of two common picking-ups of T shape carriage.
Angle steel raw material 1 is positioned on the carriage, and hydraulic press drives the curved drift 4 of system and presses down, and makes shaping outside sweep angle steel.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all technical staff in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
