The die is characterized in that an upper die (2) and a lower die (3) are included, wherein, the upper die (2) and the lower die (3) have the corresponding effective working length of an upper roller (1) and a lower roller (4) of the three-roller lapping machine, the upper die (2) comprises an upper die pressing head (2.2) and an upper die base (2.1), the lower die (3) comprises a lower die groove (3.1) and a lower die base (3.2), the upper die (2) is connected with a single upper roller (1) of the three-roller lapping machine, the lower die (3) is connected between two lower rollers (4) of the three-roller lapping machine. The method only needs one three-roller lapping machine and is matched with a special die to elongate the processing length of the groove-shaped part, thereby reducing the number of parts, not only reducing the processing and split jointing workload but also improving the production efficiency and the processing accuracy, and lowering the shipbuilding cost.

Description

Utilize the mould of three rolls plate bending machine pressing corrugated bulkhead

Technical field

The utility model relates to a kind of mould of using the three rolls plate bending machine pressing corrugated bulkhead in the hull construction process.Belong to the shipbuilding technical field.

Background technology

In the hull construction process, some boats and ships is because of design and ship type needs (as bulk freighter and oil carrier), and the subdivision cross wall of cargo hold generally is designed to grooved.General shipyard all adopts hydraulic press piecemeal pressing corrugated bulkhead now, and then is spliced into integral body.That is: according to the span between hydraulic press pressure head and the body, consider the maximum compacting length of controlled compacting precision simultaneously, corrugated bulkhead is divided into fritter (generally is 1500mm * 3000mm) to the maximum, utilize mould to be pressed into single grooved parts then, after the assay was approved, finally on moulding bed, be spliced into integral body.The above-mentioned following problem of this conventional method ubiquity:

1, general corrugated bulkhead size is approximately 20000mm * 20000mm, because of the restriction of hydraulic press working ability must be divided into a lot of small pieces, compacting workload and splicing workload are very big, and simultaneously a large amount of splicing welding joint influences is attractive in appearance, and production cost height, production efficiency are low.

2, in fact there is the mismachining tolerance that precision allows in single grooved parts, but can cause the accumulation of error and cause final error to exceed standard or the notch butt joint has some setbacks in a lot of parts splicings.Generally can only eliminate this problem, cause waste of material by placing single grooved parts butt joint mowing surplus.

3, single grooved parts are generally by controlling splicing size and precision splicing with moulding bed, cause the place dull and utilization rate is not high.

Owing to above reason, cause boats and ships corrugated bulkhead fabrication cycle long, quality control difficulty, economy are also bad.

Summary of the invention

The purpose of this utility model is to overcome the drawback of the conventional hydraulic press pressing corrugated bulkhead of above-mentioned usefulness, and a kind of mould that utilizes the three rolls plate bending machine pressing corrugated bulkhead that can reduce processing and splicing workload is provided.

The purpose of this utility model is achieved in that a kind of mould that utilizes the three rolls plate bending machine pressing corrugated bulkhead; comprise upper die and lower die; the last roller of upper die and lower die and three rolls plate bending machine is suitable with effective active length of following roller; patrix is connected the single of three rolls plate bending machine and goes up on the roller; counterdie is connected between two following rollers of three rolls plate bending machine; described patrix comprises patrix pressure head and upper die base; counterdie comprises counterdie groove and lower die base; general last roller of three rolls plate bending machine and the effective active length of following roller reach more than the 10000mm, and the compacting length of mould that also just means pressing corrugated bulkhead is more than 10000mm.

Adopt knockdown type to be connected between described patrix pressure head and the mold base, the counterdie groove design becomes adjustable type.

The utility model has the advantages that:

1, overcome of the restriction of conventional oil press, can be lengthened to processing length more than the 10000mm, reduced number of components, reduced compacting workload and splicing workload, reduced production costs and enhance productivity single grooved part dimension.

2, single grooved parts time processing moulding simultaneously because of the part length lengthening has reduced longitudinal spliced number of times, thereby has been eliminated accumulated error, has reduced the splicing difficulty, has improved corrugated bulkhead integral manufacturing precision.

3, Jia Chang single grooved parts can splice on level land or straight moulding bed, have improved the flexibility in splicing place.

4, compacting and the relative simplification of splicing are accelerated the corrugated bulkhead fabrication cycle, and quality control is relatively easy.

The extended compacting length of grooved parts of mould described in the utility model, this mould is knockdown type with the last roller of three rolls plate bending machine with being connected of following roller simultaneously, does not influence the roll bending function of three rolls plate bending machine.

To sum up, the utility model method only needs a three rolls plate bending machine, and be equipped with special-purpose mould, the grooved component processing that can extend length, thus number of components reduced, not only reduced processing and splicing workload but also enhanced productivity and machining accuracy, reduce the shipbuilding cost, improve the machine service efficiency, shorten ship building period, and can simply and effectively control corrugated bulkhead and make quality.

The specific embodiment

Referring to Fig. 1, the utility model has been announced a kind of mould that utilizes the three rolls plate bending machine pressing corrugated bulkhead in the shipbuilding process:

The upper die base 2.1 and the lower die base 3.2 that cooperate with roller according to the gap design mould upper and lower mould of the diameter of the upper and lower roller of three rolls plate bending machine and twice rollers; Determine the length of mould according to the effective active length of three rolls plate bending machine; Knuckle size and the patrix pressure head 2.2 of knuckle place circular arc design upper and lower mould and the size of counterdie groove 3.1 according to the corrugated bulkhead notch.

Patrix 2 is connected by screw-button with last roller 1 and fix, counterdie 3 is placed on two following rollers 4, then by the moving downward rolling inspection upper and lower mould of patrix mesh degree of top roll cornice and suitably adjustment, lie on the accurate position of counterdie cutting and drawing the sheet material of suppressing line at last, move downwards the notch of grooved parts once suppressed by the moving patrix of top roll cornice and put in place, also suitably repair pressure with notch model inspection pressing result.

According to the effective active length of difference but the identical three rolls plate bending machine of roller diameter, can be several sections connection types of mould design mix, reduce the Mold Making cost and improve the applicability of mould; According to the size and the angle of grooved parts notch, can be designed to knockdown type to patrix pressure head 2.2 and upper die base 2.1, counterdie groove 3.1 is designed to adjustable type, enlarges the supporting rate of compacting scope and raising mold base.
