The processing work efficiency of new pressure die for processing a steel pipe is three times higher than that of traditional pressure die.

Description

Steel cylinder processing pressing mold

(1) technical field

The utility model relates to a kind of hull cold working hydraulic press pressing mold, particularly relates to when the low-alloy high-strength hull structural steel cylinder of less, the book wall thickness of processing diameter, is installed in the special die on the hydraulic press.Belong to and build the ship technical field.

(2) background technology

On hydraulic press during the processing column body, the dip mold of hydraulic press is normally made with cast steel or cast iron, its cross section is generally V-type and U type, top die normally is processed into difform machined surface with the steel plate of 20mm～40mm, and adding needs repeated multiple times processing man-hour, because upper and lower pressing mold processing cross section is less, add and to produce big impression to work piece man-hour, particularly evident than the cylinder of book to wall thickness, product quality does not reach requirement, and operating efficiency is lower simultaneously.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, easy to make, when processing book wall thickness cylinder, can not produce impression, and the steel cylinder of high efficiency processing pressing mold.

The purpose of this utility model is achieved in that a kind of steel cylinder processing pressing mold, comprises a dip mold and a seaming chuck,

Described dip mold upper surface is processed with and the corresponding concaved circular cambered surface of processed cylinder, and dip mold bottom is fixed with a base plate, is welded with four little hangers on base plate four angles, and described base plate adds and is fixed on man-hour under the hydraulic press on the workbench;

Described seaming chuck lower surface is processed with and the corresponding convex arc surface of processed cylinder, a fixedly connected riser makes progress in the middle of the seaming chuck upper surface, the riser left and right sides is provided with the reinforcement gusset and is used for strengthening, riser top center fixed connects a transverse slat, the edge, both sides, front and back of described transverse slat is concaved with two U type breach respectively, adds by this breach seaming chuck to be fixed on the hydraulic press hydraulic piston (going up platen) man-hour.

The beneficial effects of the utility model are:

Make simply, easy accessibility, the machining accuracy height, no impression does not have the processing resilience, high efficiency.Use steel pipe of new pressing mold processing, be to use three times of conventional die processing work efficiency.

(5) specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe processing method of the present utility model in detail.

Referring to Fig. 1～3, the utility model steel cylinder processing pressing mold comprises a dip mold 5 and a seaming chuck 1.When the processing column body, this dip mold 5 and a seaming chuck 1 will be fixed on respectively on last hydraulic piston (the going up platen) 8 and following workbench of hydraulic press.

Described dip mold 5 adopts the low-alloy high-strength hull structural steel of the wide 500mm of thick 60mm to process, length is 3050mm, enlarged effective active length of hydraulic press like this, these dip mold 5 upper surfaces are processed with and the corresponding concaved circular cambered surface 5.1 of processed cylinder, and these concaved circular cambered surface 5.1 radiuses are 225mm for the 198mm width.These dip mold 5 bottoms and thickness are that 40 * 700 * 3200 base plate 6 is integrally welded, so that dip mold can easily be fixed on the following workbench of hydraulic press, are welded with a little hanger 7 on base plate 6 four angles, so that dip mold dismounting handling.

Described seaming chuck 1 adopts the low-alloy high-strength hull structural steel of the wide 160mm of thick 60mm to process, length is 3050mm, be complementary with dip mold 5, like this can processing length less than the steel pipe of 3000mm, this seaming chuck 1 lower surface be processed with the corresponding radius of processed cylinder be the convex arc surface 1.1 of 160mm for the 198mm width, cooperate with the concaved circular cambered surface 5.1 of dip mold, can process the cylinder of φ 408 * 8, (arc radius of going up dip mold has been considered processed cylindrical processing springback capacity), the middle fixedly connected riser 2 that makes progress of seaming chuck 1 upper surface, respectively there is a hole 2.1 on both sides before and after riser 2 upper ends.Riser 2 left and right sides are provided with strengthens gusset 4, and riser 2 top center fixed connect a transverse slat 3, and the edge, both sides, front and back of described transverse slat 3 is concaved with two U type breach 3.1 respectively.Seaming chuck 1 is integrally welded with riser 2, transverse slat 3 and reinforcement gusset 4.Four U type breach 3.1 on the both sides, front and back of transverse slat 3 can make the easy accessibility of set bolt between top die, hydraulic piston (going up platen).Whole cylinder process need be processed on vertical limit of cylinder steel plate as long as 10 times just can reach quality requirement, and adopts traditional diamond-making technique processing column body to need more than 30 time, just can machine.

When having represented the processing column body, adopts Fig. 4 the special-purpose stereogram of going up dip mold processing.Add man-hour, two vertical limits from work piece begin processing earlier, suppress to the centre respectively piecemeal again, in the middle of the processing, at last abutment joint is placed horizontal level to be placed on the dip mold then, top die presses down only abutment joint closure, behind the arc welding tack-weld, process finishing.
