Abstract

The utility model discloses an angle steel inward bending mold which comprises an upper mold and a lower mold. The upper mold is composed of a hydraulic machine connecting plate and a bending rib block, and the lower mold is composed of a bottom plate and a bent supporting frame for holding angle steel. The bending rib block is matched with the bent supporting frame in the bending mold, and the shape of the bending mold is the same as that of the bent angle steel needing to be made. The angle steel inward bending mold has the advantages that according to the angle steel inward bending mold, bending operations needing to be completed manually in the prior art are completed by a machine, the bending effect is good, product quality is high, labor is saved, and cost is reduced.

Description

Lateral flexure bending mould processed in a kind of angle steel

Technical field

The utility model relates to angle steel bending technical field, relates in particular to lateral flexure bending mould processed in 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 interior lateral flexure of angle steel is bent all is wherein to cut next piece with the high temperature firelock on one side at angle steel first, then the workman makes firmly pincers or iron staff that angle steel is bent, the method of this artificial bending angle steel not only will expend in a large number muscle power of workman, 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.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of i.e. accurate and labour-saving angle steel interior lateral flexure bending mould processed.

For addressing the above problem the technical scheme that the utility model takes be:

Lateral flexure bending mould processed in a kind of angle steel, described bending mould processed comprises upper die and lower die two parts, patrix is comprised of hydraulic press connecting plate and the curved muscle piece of system, counterdie is comprised of the curved bracket of base plate and placement angle steel, the curved muscle piece of system and curved bracket match in the described bending mould processed, are shaped as the shape of the required crooked angle steel that makes.

The angle steel raw material is wherein cut away one with the high temperature firelock on one side along the centre, do preliminary treatment, another side is left intact, shown under being cut one be triangle, triangular angles is decided according to the number of degrees of angle steel needs bending, triangle drift angle angle equals angle steel needs the crooked number of degrees, and the one side that is not cut in the curved engineering of angle steel system bending is on one side two waists of triangle can be overlapping along with the bending of another side when angle steel system is curved for the triangular open space of angle steel under being cut.

To carry out interior lateral flexure system curved with being installed in outer lateral flexure bending mould processed on the hydraulic press with the angle steel raw material of preliminary treatment.

Obtain crooked angle steel in the finished product.

The utility model has the advantage of, with the outer curved work of lateral flexure system of artificial angle steel originally, changing machinery into through the utility model finishes, saved greatly workman's amount of labour, and the curved production efficiency of the mould system of employing is high, the outer lateral flexure angle steel bending that obtains is more accurate, and product is not easy to occur 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 processed.

Fig. 2 is interior lateral flexure bending mould schematic diagram processed.

Fig. 3 is the interior crooked angle steel schematic diagram of finished product that this technique obtains.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further details:

Lateral flexure bending mould processed in a kind of angle steel as shown in Figure 2,

Such as Fig. 1 angle steel raw material 1 is wherein cut away one with the high temperature firelock on one side along the centre, do preliminary treatment, another side is left intact, shown in part under being cut be triangle 2, triangular angles is decided according to the number of degrees of angle steel needs bending, triangular angles is decided according to the number of degrees of angle steel needs bending, triangle drift angle angle equals angle steel needs the crooked number of degrees, the bending of one side of not being cut in the curved engineering of angle steel system is on one side two waists of triangle can be overlapping along with the bending of another side when angle steel system is curved in triangle 2 spaces of angle steel under being cut.

Bending mould processed comprises upper die and lower die two parts as shown in Figure 2, patrix is comprised of hydraulic press connecting plate 3 and the curved muscle piece 4 of system, counterdie is comprised of the curved bracket 5 of base plate 6 and placement angle steel, the curved muscle piece 4 of system matches with curved bracket 5 in the described bending mould processed, is shaped as the shape of the required crooked angle steel that makes.

Claims

1. the interior lateral flexure bending mould processed of angle steel is characterized in that described bending mould processed comprises upper die and lower die two parts, and patrix is comprised of hydraulic press connecting plate and the curved muscle piece of system, and counterdie is comprised of the curved bracket of base plate and placement angle steel.

2. lateral flexure bending mould processed in described a kind of angle steel according to claim 1 is characterized in that, makes curved muscle piece in the described bending mould processed and curved bracket matches, and is shaped as the shape of the required crooked angle steel that makes.
