Abstract
The utility model relates to a rotary extrusion mould with double layers of balls. A fixing type rotary extrusion mould part with balls is composed of an upper mould (8), a mould plate for an upper mould (9), a mould plate sleeve for an upper mould (10), balls, etc. An adjustable rotary extrusion mould part with balls is composed of a lower mould (1), a movable mould (2), a sliding key (3), a pressing plate (4), screw nails (5), a mould seat for a lower mould (6), a mould sleeve for a movable mould (7), the balls, etc. Because rotary extrusion forming in two times can be realized in travel in one time on the same mould, the axial flatness of a metal long pipe with a thin wall in rotary extrusion is increased, the precision of the outside dimension of a rotary extrusion piece is increased, and the deformation rate of the rotary extrusion is increased.
Description
The utility model belongs to a kind of metal spinning mould.
In order to satisfy modern military and civilian demand, particularly in order to satisfy in electronics industry and the wind instrument industry high-precision requirement for thin-wall long pipe, for a long time, people are in the axial glacing flatness that improves thin-wall long pipe and improve aspect two of the mould pressing deformation rates, constantly seek new and better solution.In the metal spinning forming technique, the processing method of thin-wall long pipe has polytype, comprising distinct methods such as ball spinning, roller spinning are arranged.Development along with the hyperfrequency electron tube, requirement to the shell dimensional accuracy is also improving constantly, for example, because the glacing flatness of tube shell of traveling wave tube has direct influence to device performance, on 100 mm lengths, be no more than 0.02 millimeter so require the nonstraightness of shell to reach.In existing technology, long tube mould pressing technology is finished on a mould pressing mould, and the required precision of the inaccessible glacing flatness of spinning spare also is difficult to improve the deformation rate of mould pressing.In order to seek redress, can adopt manual or special-purpose straightener to carry out the aligning work of long tube, but this way expend man-hour, and repetitive operation, in big production, influence the raising of productivity ratio.Can be by improving the revolving property that processing conditions and machining state improve material for improving deformation rate, and then improve the rotary pressure deformation rate, but this needs to increase a lot of back works and complicated procedure again.
The purpose of this utility model is exactly a kind of spinning mould that designs with improving the mould pressing deformation rate for the axial glacing flatness that improves socket shape part, be on general ball spinning mold foundation, change its traditional version, by double-deck ball spinning shaping dies, in the once-through operation process, the long tube shell is carried out mould pressing twice, to obtain accurate axially glacing flatness and bigger mould pressing deformation rate.
In conjunction with the accompanying drawings 1 and 2, structure of the present utility model is described.
Description of drawings:
Fig. 1 is the installation diagram of double-deck ball spinning mould.
Fig. 2 is the ABCD cutaway view of double-deck ball spinning mould.
Mould divides two ones, the first half is called fixed ball spinning mould part, it is made up of patrix (8), patrix template (9), patrix die sleeve (10) and ball (11), under the cooperation of core (12), spinning blank (13) is carried out the mould pressing first time.The latter half is called adjustable ball spinning mould part, it is made up of counterdie (1), dynamic model (2), feather key (3), pressing plate (4), screw (5), counterdie die holder (6), dynamic model die sleeve (7) and ball (11), under core (12) cooperates, spinning blank (13) is carried out the mould pressing second time.Like this, in the one stroke of spinning machine, just can realize the spinning blank is carried out mould pressing twice, break the traditional mode that in the one stroke of spinning machine, can only carry out the ball spinning of a mould pressing the spinning blank.
Because the flange cunning above the counterdie (1) fits in the following groove of patrix (8), thereby make fixed ball spinning mould part and adjustable spinning mould part constitute an integral body.
At fixed ball spinning mould part, patrix template (9) is sliding to be fitted in the groove of patrix (8), patrix die sleeve (10) is sliding to be fitted in the endoporus of patrix (8), be placed on the radial position that the ball (11) on the patrix template remains unchanged on the horizontal direction of this kind spinning mould, promptly can only be spun to a kind of part of outside dimension with a kind of mould.
At adjustable ball spinning mould part, there are the counterdie (1) of radial groove and dynamic model (2) in the upper surface, and (counterdie (1) inwall has screw thread together by threaded engagement, dynamic model (2) outer wall has screw thread and an axial keyway), keyway, the horizontal component that the vertical component of ┌ type feather key (3) is arranged in dynamic model (2) is placed on the radial groove of counterdie upper surface, the hoisting depth of pressing plate (4) restriction ┌ type feather key, screw (5) is fixed on pressing plate (4) on the dynamic model.Counterdie die holder (6) is sliding to be fitted in the groove of counterdie (1), and endoporus has dynamic model die sleeve (7) chute of the conical surface in the groove of dynamic model (2).Ball (11) is placed on the upper surface of counterdie die holder (6).Mentioning ┌ type feather key (3) rotates with respect to counterdie (1), dynamic model die sleeve (7) is moved with respect to counterdie die holder (6) is upper and lower, thereby change the radial position of ball (11), promptly can be spun to multiple part with various outer diameter size with a kind of mould in this kind spinning mould horizontal direction.
Two parts in the above-mentioned double stack mold can also be changed the position in implementation process, namely the spinning blank is being carried out the first time during mould pressing, also can adopt the adjustable rotary compression mould, the spinning blank is being carried out the second time during mould pressing, particularly under a large amount of conditions of production, also can adopt fixed ball spinning mould.
Advantage of the present utility model is summed up as three aspects: (1) has therefore improved deformation rate owing in the one stroke of spinning machine the spinning blank has been realized mould pressing twice, shortens the rotary pressing processing time, improves spinning production efficiency. (2) be spun for the first time the existing axial nonstraightness of part during mould pressing, because in second time during mould pressing, second layer spinning mold causes opposite stress state being spun part inside, forces that to be spun part in the opposite direction crooked, plays certain straightening function. (3) because secondary mould pressing adopts little traverse feed usually, So the sizing effect is arranged, thereby improves the radial dimension precision of thin-wall long pipe.
This mould is applicable to the various metal materials of processing, and various draw ratios can satisfy the high-precision requirement of socket shape part in electronics industry and the wind instrument industry by the workpiece accuracy of this Mould Machining.
The material that this mould adopted is: counterdie die holder (6), dynamic model die sleeve (7), patrix template (9), patrix die sleeve (10) and core (12) are chromium tungsten manganese alloy tool steel, high-speed steel or other mould steel, and other parts are all No. 45 steel or other medium carbon steel.
