Abstract
The invention discloses a manufacturing process for a cylindrical blank of an annular element, which comprises the following steps: upsetting a heated high-temperature steel ingot; chamfering and rolling the steel ingot till the steel ingot is in a required size; flatting an end face and then returning to a furnace for heating and preserving heat; placing the blank onto a lower punch of a lower punching operation platform; adjusting the position for aligning the center of the blank with the center of the lower punch, and then punching a lower blind hole; moving the blank to an upper punching operation platform and punching an upper blind hole; placing the blank to a hydraulic press gasket ring; placing a conical gasket punch into the upper blind hole; driving an upper flat anvil of the hydraulic press to move downwards and punching the middle core material through the gasket punch; and then turning the blank for 180 degrees and jacking out the gasket punch by the upper punch of the hydraulic press. According to the method, within an allowed scope of hydraulic press tonnage, the manufacturing for the cylindrical blank of the ultrahigh annular element is finished by using the gasket punch and the gasket ring, the problem of insufficient length of common punch is solved and the cylindrical blank is supplied for the following rolling of the annular element.
Description
Technical field
The present invention relates to material is the manufacturing process of a kind of annular element tubular blank of structural alloy steel or ordinary carbon steel.
Background technology
At present, the required a large amount of annular elements of industry such as naval vessel, nuclear power, mining machinery are produced through the method for roll forming, and the poor efficiency of manufacturing process makes whole rolling efficiency be affected usually.Therefore in order to increase work efficiency, process the tubular blank after the higher blank processing commonly used, again with the tubular blank after roll forming, heat treatment, machined, promptly may be partitioned into some finished product annular elements.Yet receive the restriction of punch length, the blank height that can process is still limited, has limited the further raising of working (machining) efficiency.
Summary of the invention
Technical problem to be solved by this invention is: the manufacturing process that a kind of annular element tubular blank is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of manufacturing process of annular element tubular blank comprises the steps:
1) steel ingot of temperature after heating between 1200 ℃-1300 ℃ passed through the hydraulic press jumping-up;
2) steel ingot behind the jumping-up is carried out chamfered edge, round as a ball, carry out planar end surface then;
3) blank is returned stove and carry out heat tracing, holding temperature is 1200 ℃-1300 ℃, is incubated 2-4 hour;
4) will descend the punch work platform to move to the blank below; Low punch is fixed on down on the punch work platform; Blank is fixed on the manipulator of hydraulic press; Move to the low punch top and make blank center and low punch centrally aligned, the last flat anvil that drives hydraulic press moves downward, and makes low punch punching out on blank go out blind hole down;
5) remove down the punch work platform, will go up the punch work platform and move to blank below, the upper punch of hydraulic press is moved to operating position, flat anvil below, the last flat anvil drive upper punch that drives hydraulic press moves downward, thus on punching out goes out on the blank blind hole;
6) remove upper punch and last punch work platform, gasket ring is moved to the blank below, adjust the manipulator height and make blank move to the gasket ring top, will fill up to dash and put into blind hole, the last flat anvil that drives hydraulic press moves downward through pad and removes middle core material in a state of excitement;
7) through manipulator blank is overturn 180 °, the upper punch with hydraulic press moves to operating position, flat anvil below once more, and the last flat anvil that drives hydraulic press moves downward through upper punch rushes to summit out pad.
Described pad dashes and is conical long drift, and greater than annular element tubular blank height, pad is 5 ° ~ 10 ° towards the conical surface and axis angle to pad towards length.
Advantage of the present invention is: in the scope that the hydraulic press tonnage allows, utilize pad to dash the manufacturing of having accomplished the cylindrical member blank of extra-high-speed annular element with gasket ring, solved the not enough problem of common punch length, be the rolling tubular blank that provides of follow-up annular element.
Description of drawings
Fig. 1 is a pad of the present invention hole process sketch map in a state of excitement.
Among the figure: 1, pad dashes, and 2, blank, 3, gasket ring, 4, go up blind hole, 5, blind hole down, 6, middle core material.
The specific embodiment
In order to understand process program of the present invention better, below through embodiment particularly and combine accompanying drawing that (is the example explanation to make the tubular blank that a 42CrMo material is of a size of Φ 1020 * 1700mm) at length is described:
It is high to 1550mm that the manipulator of raw material steel ingot through hydraulic press that 1) will be heated to 1250 ℃ high 1960mm is clamped to down on the flat anvil workbench jumping-up;
2) blank behind the jumping-up 2 is carried out chamfered edge, round as a ball to Φ 1020 * 1700mm, carry out planar end surface then;
3) blank 2 is returned stove and be heated to 1250 ℃, be incubated 2 hours;
4) will descend the punch work platform to move to blank 2 belows; Low punch is fixed on down on the punch work platform; Blank 2 is fixed on the manipulator of hydraulic press; Move to the low punch top and make blank 2 centers and low punch centrally aligned, the last flat anvil that drives hydraulic press moves downward, and makes low punch punching out on blank 2 go out the following blind hole 5 of dark 700mm;
5) remove down the punch work platform; To go up the punch work platform and move to blank 2 belows; The upper punch of hydraulic press is moved to operating position, flat anvil below, and the last flat anvil drive upper punch that drives hydraulic press moves downward, thus punching out on the blank 2 go out dark 700mm on blind hole 4;
6) remove upper punch and last punch work platform; Φ 1150/ Φ 600 * 250mm gasket ring 3 is moved to blank 2 belows; Adjustment manipulator height makes blank 2 move to gasket ring 3 tops; The conical pad of Φ 450/ Φ 420 * 1700mm is dashed 1 put into blind hole, the last flat anvil that drives hydraulic press moves downward through pad and washes away middle core material 6 towards 1;
7) through manipulator with 180 ° of blank 2 upsets, the upper punch with hydraulic press moves to operating position, flat anvil below once more, the last flat anvil that drives hydraulic press moves downward will fill up towards 1 through upper punch and ejects.
The blank 2 that processes need melt down and be heated to 1250 ℃, and insulation is used in order to next procedure then.
Owing to adopted blind hole 5 and last blind hole 4 under the first punching out; Utilized again pad dash 1 wash away with gasket ring 3 in the middle of the processing step of core material 6; In the scope that the hydraulic press tonnage allows, accomplish the manufacturing of extra-high-speed annular element cylindrical member blank, solved the not enough problem of common punch length.
