Abstract
The invention provides a method for manufacturing a steel structure thick-plate adapting piece with a round top and a square bottom, wherein the steel structure thick-plate adapting piece has a simple structure and is convenient and quick. A thick plate is selected, two points are determined on the long edge of the thick plate and serve as base points to draw radial lines to the long edge of the other side, and the terminal points of the radial lines are on the long edge of the other side; and only one intersection is permitted to form on the long edge of the other side between the radial lines of two base points. After the processing is finished, a press is adopted for extruding to extrude the thick plate into a construction member of which the long edge of one side is provided with two right angles, and the long edge of the other side is semicircular. The two construction members of the same specification are welded to form a standard adapting piece with a round top and a square bottom. In the method, few pieces of equipment are adopted, and the method is simple and quick to manufacture, has the advantages of wide applicable range, little manpower and resource consumption and short manufacture period, can be used for different thick-plate adapting pieces with a round top and a square bottom and can be produced in batches.
Description
Technical field
The present invention relates to a kind of preparation method of connector, be specifically related to a kind of preparation method of connector of hemispherical dome type connector type.
Background technology
Hemispherical dome type connector is used in a lot of fields to some extent, and such as the attaching parts of taking over as depositing dust pipe, water pump in fields such as draining, depositing dusts, its structure is a two-way pipeline, and one side is square, and another side is circular, is used for connecting the different interface in two ends.
Hemispherical dome type connector is generally made by forging, but the connector percent defective of forging is high, and cost is high, and difficult quality is guaranteed.The patent of invention of China Patent Publication No. CN1548255 discloses the manufacture method that a kind of hemispherical dome shape water pump that adopts forging method to produce is taken over.The blank of making first forging and pressing usefulness with mechanical means, again forging molding in particular manufacturing craft; Blank be shaped as the upper end flanged up big and down small taper pipe, it is suitable that the height of taper pipe and water pump are taken over the finished product height, the wall thickness of the wall thickness of taper pipe and the square tube of finished product part is suitable, the upper end diameter of taper pipe is identical with the upper end that hemispherical dome type connector shape water pump is taken over, the girth of the cross section of the cross-sectional diameter of taper pipe and the square tube of finished product is suitable with towering ratio, and the lower end diameter of taper pipe is equivalent to the girth of square end face and the ratio of π.The method cost is lower, and the connector quality of producing is better.But the method also is not suitable for the steel construction hemispherical dome type connector that weight is large, material is thick.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, method of steel construction slab hemispherical dome type connector easily and efficiently of making.
To achieve these goals, technical scheme of the present invention is:
Getting length is that hemispherical dome type connector section girth 1/2, width are the slab of hemispherical dome type connector height, determines that on the long limit of slab distance between 2 points, is the distance on a limit aspect the hemispherical dome type connector at 2.
For the ease of making, these 2 the distance with 2 place one sheer plank minor faces is identical respectively.
After determining 2 positions, draw radiation as basic point to the long limit of an other side take these 2, the terminal point of radiation should be on the long limit of an other side, and only allows on the long limit of an other side intersection is arranged between the radiation of two basic points.
According to the difference of hemispherical dome type connector specification, the radiation number of each basic point is also different, but the angle between each basic point adjacent radiation line should be to be no more than 5 ° as good.
After above-mentioned being disposed, a side minor face of slab is fixed in the driving, slab is put into heavy-duty press, start heavy-duty press, the control displacable platen begins extruding from a side that is fixed on the slab in the driving according to the radiation of finishing.In the extrusion process, centered by the radiation basic point, the long limit of the slab at radiation basic point place can be squeezed into 90 ° right angle centered by basic point, the long limit of the opposite side slab of basic point can be squeezed into according to the pattern of radiation sectional arc, and slab is squeezed into the long limit of a side two right angles, the long limit of opposite side are arranged is semicircular member the most at last.
With two Member Weldings of same specification together, just become the hemispherical dome type connector of a standard.
For convenience of explanation the present invention does further narration to the respective material in the said process, instrument, device.
The slab that the present invention is corresponding, requirement are the slabs of steel construction, and the thickness of slab is not less than 5mm.
The forcing press that the present invention is used, Separated oil jack, because the bearing capacity of each Separated oil jack is limited, sometimes in order to push the larger slab of thickness, need to increase the bearing capacity of forcing press, can combine a plurality of Separated oil jacks this moment.
The invention has the beneficial effects as follows: 1, device therefor is seldom made simple and fast.2, applied widely.Can be used in the slab hemispherical dome type connector of a lot of different sizes.3, consumption manpower and resource are few.General three people just can constantly make.So 4, whole manufacturing process can be interrupted to utilize intermittently and ceaselessly be done, the cycle of making a member is short, so production that can be in batch.
Description of drawings
Fig. 1 is press structure schematic diagram of the present invention.
Fig. 2 is the slab schematic diagram after the setting-out of the present invention.
Fig. 3 is the hemispherical dome type connecting-piece structure schematic diagram that the present invention prepares.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
As shown in Figure 1, on the forcing press 3, displacable platen 1 and lower plate 2 are arranged, lower plate 2 is fixed.In when work, slab 4 is placed on the lower plate top, starting pressure machine, forcing press promote displacable platen 1 press slab 4 of exerting pressure downwards.Slab is made into a member of hemispherical dome type connector connector by extruding.
In actual production process, the forcing press that the present invention can adopt five Separated oil jacks to form, total bearing capacity can reach 500 tons.
As shown in Figure 2, the long limit of slab 4 determine 2: 5 and 6,5 and 6 two between distance be the distance on a limit, hemispherical dome type connector aspect.
For the ease of making, this 2: 5 with 6 the distance with 2 places, one sheer plank minor face 7 and 8 is identical respectively.
After determining 2 positions, draw radiation 9 as basic point to the long limit of an other side take these 2, the terminal point of radiation should be on the long limit of an other side, and only allows to intersect on the long limit of an other side between the radiation that draws from two basic points.
According to the difference of hemispherical dome type connector specification, the radiation number that draws from basic point is also different, but the angle between the adjacent radiation line should be to be no more than 5 ° as good.
Accompanying drawing 3 is the hemispherical dome type connector connecting-piece structure schematic diagram of the present invention's preparation.
