Abstract
The present invention, rolling, jetting and pressing process, is used for producing end plate and flange for pipe pile. The production apparatus comprises heater, puncher, rolling and jetting unit, under die, upper die and water press. The present invention has high production efficiency and the product needs no further machining. The present invention can realize mechanized mass sproduction in high product quality, low material consumption and low power consumption.
Description
The invention belongs to mechanical, cement products class technical field.
The present invention produces " pretensioned prestressed concrete pipe pile " end plate, ring flange.But also widespread production steel pipe joint ring flange.
Current production pile tube end plate, ring flange all are to adopt traditional production method and technology: cut turning with whole steel plate and form, be cut into strip with whole steel plate and simmer red curved circle, and welding tractor is cut and formed.Block red the forging of stewing with whole first steel, simmer red curved circle, and weldering is annealed again, and fine finishining forms.Utilize useless, the selected melting of old iron and steel, founding moulding, heat treatment, fine finishining to form besides.And pile tube end plate, ring flange diameter be all more than 300 millimeters, and maximum gauge has 1 meter, and the specification kind is also few, only kind surplus in the of ten.At present all in individual workshop or general process unit produce, sneak into waste and old steel material unavoidably and do not meet and produce pile tube end plate, the processing of ring flange raw material input, make product, supplying with pile tube factory uses, directly influence the pile tube total quality, in case be driven underground, be the whole construction project serious hidden danger that is in covert, its consequence is difficult to estimate.
More than several conventional production methods and technology, all be difficult to carry out mechanization, production in enormous quantities, waste of raw materials is big, energy consumption is also high, product cost height, social benefit are poor, relation between supply and demand complexity, defective such as drawback is many, and noise is big in the production process, and is seriously polluted.
Purpose of the present invention: at above-mentioned existing problems, can comprehensively solve, overcome, relate to product high-quality, a kind of novel production method and the technology of quality homogeneous comprehensively.
General plotting of the present invention: " once heating, one-shot forming ".Different-diameter (blank) A3 round steel (optimum section is rolled into ellipticity) is heated to 700～750C through firing equipment, send into and roll injection device and enter into ring flange bed die tangential direction breach, penetrate and roll continuous rotation, bed die rotates simultaneously, this moment is by computational length and volume, the shearing equipment blanking, when blank is full of bed die, patrix is compacting downwards immediately, should avoid blue shortness temperature (200～400 ℃) and red crisp temperature (700～900 ℃) during compacting, the two-way clip of moment blank produces liquid crystal under the effect of high pressure, otch is bonding, and the finished product of making falls to breaking away from bed die.Whole flow process is all taked automatic program control, and a cycle period needs 2～3 minutes approximately.As accompanying drawing 1.
Superiority of the present invention is: can realize mechanization, specialization, production in enormous quantities, found a superior supply and demand environment.Need not metalworking (wherein deformed bar hole, tension linked tendons hole after the formed product.Pile tube factory is according to designing requirement, and main muscle varies in size, and the radical difference by oneself).Product novelty, mechanical performance reach the GB requirement fully, and raw material can save 30～40%, and energy consumption is low, and product cost is low, and be low approximately by 25～30%, pollution-free in the process, noise is low, the novel production decision that labor productivity is high.
Description of drawings:
Fig. 1 is " rolling compacting (die forging) method of penetrating " simple and clear flow chart.Among the figure: 1, blank (round steel) 2, feeding roller 3, firing equipment 4, punching equipment 5, to roll injection device 6, moulding bed die 7, be full of bed die red heat blank Fig. 2 be among the pile tube ring flange example finished figure figure: 8, Φ 500/ Φ 340-80 * 20 ring flange planes 9, to survey view Φ 1 be that 500 millimeters Φ 2 are that 340 millimeters t are 20 millimeters of thicknesss of slab
Example: with Φ 500/ Φ 340-80 * 20 pile tube end plates (ring flange) is example: end plate net weight 16.57Kg, length of run 1.319M, volume 0.002111M
3, select A3 round steel diameter of phi 45mm for use, length 1.380M, volume 0.002195M
3, weight 17.23Kg.Through being heated to 700～750 ℃, to roll and be mapped to bed die through rolling injection device, this moment, blank temperature was controlled at 550～600 ℃, and patrix is suppressed immediately, and formed product breaks away to fall.As accompanying drawing 2.
Claims (3)
1, " rolls compacting (die forging) method of penetrating " by firing equipment, punching equipment, penetrates and roll device, bed die, patrix, hydraulic press and formed, but main pile tube end plate, ring flange, the also widespread production steel pipe joint ring flange produced, it is characterized in that: blank is round steel (optimum section rolls into ellipticity), once heating is rolled the form of penetrating and is entered bed die (heat dissipation is controlled at about in the of 150 ℃) on the way, patrix hot pressing, otch is bonding, one-shot forming, and the finished product interlock is fallen.
2, according to claim 1 it is characterized in that: blank is a round steel, once heating, and patrix hot pressing, otch is bonding, one-shot forming, the finished product interlock is fallen.
3, the heating and temperature control that it is characterized in that according to claim 1 is at 700～750 ℃, and hot pressing temperature is controlled at 550～600 ℃, avoids 200～400 ℃ of blue shortness temperature, 700 ℃ of hot-short temperature.
