Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molybdenum-rhenium alloy rod processing, and particularly relates to a molybdenum-rhenium alloy rod twisting and pressing processing die. BACKGROUND

[0002] The molybdenum-rhenium alloy blank produced by the vacuum melting method has the advantages of low cost and easy industrial production, but the molybdenum-rhenium alloy blank prepared by the method has the problem of low relative density, and even after the treatment of die pressing or isostatic pressing, the relative density is only about 90%; in order to ensure the density of the final product of the molybdenum-rhenium alloy rod produced by the vacuum melting method, the molybdenum-rhenium alloy rod adopts a large-diameter extrusion, a medium-diameter forging and a small-diameter rotary forging continuous stress forming processing technology, and finally a high-density molybdenum-rhenium alloy rod is obtained; in the existing medium-diameter forging processing procedure, the molybdenum-rhenium alloy rod is manually rotated and forged by using a simple forging die, and the processing efficiency is low and the size precision is low, and in particular, due to the low size precision of the manual rotary forging, the machining allowance of the final product has to be increased, which causes the utilization rate of the molybdenum-rhenium alloy to be low, and seriously affects the economic benefits of the enterprise. SUMMARY

[0003] In order to overcome the deficiencies in the background art, the present application discloses a molybdenum-rhenium alloy rod twisting and pressing processing die, which comprises an upper die, a lower die and a sliding table, the upper die is movably arranged on the upper portion of the lower die, and the lower die is fixedly arranged on the upper portion of the sliding table; an upper twisting and pressing plate is fixedly arranged in the upper die, a lower twisting and pressing plate is fixedly arranged in the lower die, and a molybdenum-rhenium alloy rod to be processed is placed between the upper and lower twisting and pressing plates; when the upper die moves downward relative to the lower die, the lower die moves horizontally on the sliding table, a twisting and pressing compound motion is formed between the upper and lower twisting and pressing plates, and the twisting and pressing processing of the molybdenum-rhenium alloy rod is realized.

[0004] In order to achieve the object of the present application, the present application adopts the following technical solution: a molybdenum-rhenium alloy rod twisting and pressing processing die, which comprises an upper die, a lower die and a sliding table, the upper die is movably arranged on the upper portion of the lower die, and the lower die is fixedly arranged on the upper portion of the sliding table; an upper twisting and pressing plate is fixedly arranged in the upper die, a lower twisting and pressing plate is fixedly arranged in the lower die, and a molybdenum-rhenium alloy rod to be processed is placed between the upper and lower twisting and pressing plates; when the upper die moves downward relative to the lower die, the lower die moves horizontally on the sliding table, a twisting and pressing compound motion is formed between the upper and lower twisting and pressing plates, and the twisting and pressing processing of the molybdenum-rhenium alloy rod is realized.

[0005] Further, the upper die comprises an upper die plate, and the upper die plate is provided with an upper die plate inclined surface; the lower die comprises a lower die plate, and the lower die plate is provided with a lower die plate inclined surface; when the upper die moves downward relative to the lower die, the upper die plate inclined surface cooperates with the lower die plate inclined surface to push the lower die to move horizontally.

[0006] Further, the upper die plate inclined surface and the lower die plate inclined surface are provided with oil storage grooves, and the oil storage grooves are provided with lubricating grease, when the upper die plate inclined surface and the lower die plate inclined surface slide relative to each other, the lubricating grease in the oil storage grooves enters the contact surface between the upper die plate inclined surface and the lower die plate inclined surface, which improves the wear between the upper die plate inclined surface and the lower die plate inclined surface, and prolongs the service life of the rolling processing die.

[0007] Further, the sliding table comprises a sliding table bottom plate and a sliding table plate, and rollers are arranged between the sliding table bottom plate and the sliding table plate to support the sliding table plate to move horizontally relative to the sliding table bottom plate; after the rollers are arranged between the sliding table bottom plate and the sliding table plate, the original sliding friction between the sliding table bottom plate and the sliding table plate is changed into rolling friction, which improves the wear between the sliding table bottom plate and the sliding table plate, and prolongs the service life of the rolling processing die.

[0008] Further, the sliding table further comprises a sliding table side plate, and the sliding table bottom plate and the sliding table plate are movably connected through the sliding table side plate.

[0009] Further, the sliding table is further provided with a roller elastic limiting mechanism; during the working process of the rolling processing die, the molybdenum-rhenium alloy rod is rolled, and the upper die is initially raised, and the upper die drives the lower die to move upward, at this time, a gap is formed between the sliding table plate and the roller, and the gap causes the roller not to rotate in the initial stage of the upper die rising, which causes the roller to not be completely returned to the original position during the returning process of the lower die; with the accumulation of the working time of the rolling processing die, the position of the roller deviates, and the position deviation of the roller finally causes the rigid impact of the retainer on the sliding table end plate, which causes the retainer to be damaged; after the roller elastic limiting mechanism is arranged, the problem of the roller not being completely returned to the original position is eliminated, and the damage of the retainer is prevented.

[0010] With the technical scheme, the molybdenum-rhenium alloy rod rolling processing die has the advantages of high processing efficiency and high processing size precision, improves the utilization rate of molybdenum-rhenium alloy, and improves the enterprise benefit.

[0028] Referring to the drawings Figure 8 The lower die 2 comprises a lower die plate 2.1, a lower die top plate 2.2, a lower die side plate 2.3 and a lower rolling plate 2.4. Figure 9 The lower die plate 2.1 is plate-shaped, and the front plate surface of the lower die plate 2.1 is provided with a lower die plate inclined surface 2.1.1. Figure 10 The lower die side plate 2.3 is provided with two symmetric blocks, and the lower die side plate 2.3 is provided with a side plate sliding groove 2.3.1 at the position where the lower die side plate 2.3 and the lower die plate inclined surface 2.1.1 abut; the lower die plate 2.1, the lower die top plate 2.2 and the lower die side plate 2.3 are fixedly connected to form a frame structure with a hollow cavity, and the lower rolling plate 2.4 is fixedly connected to the lower die top plate 2.2 and arranged on the inner side of the hollow frame structure; wherein the lower rolling plate 2.4 is provided with a plurality of blocks with different thicknesses, and the rolling deformation amount of the molybdenum-rhenium alloy rod 4 can be changed when the lower rolling plate 2.4 with different thicknesses is replaced.

[0029] When the molybdenum-rhenium alloy rod rolling processing die works, the upper die plate 1.1 and the upper rolling plate 1.2 of the upper die 1 are movably arranged in the hollow cavity of the lower die 2, the upper die plate inclined surface 1.1.3 and the lower die plate inclined surface 2.1.1 abut and slide, and the sliding rails 1.1.1 of the upper die plate 1.1 are slidably arranged in the side plate sliding grooves 2.3.1 of the lower die side plate 2.3; when the upper die 1 moves downward, the upper die plate inclined surface 1.1.3 pushes the lower die plate inclined surface 2.1.1 to make the whole lower die 2 move horizontally to the right; when the upper die 1 moves upward, the sliding rails 1.1.1 push the side plate sliding grooves 2.3.1 to make the whole lower die 2 move horizontally to the left.

[0030] Referring to the drawings Figure 11: The slide 3 comprises a slide base plate 3.1, a slide plate 3.2, rollers 3.3, slide side plates 3.4, slide end plates 3.5, and a retainer 3.6; the slide side plates 3.4 and the slide end plates 3.5 are fixedly arranged at the side edges of the slide base plate 3.1 to form a rectangular cavity; the retainer 3.6 is arranged at both ends of the rollers 3.3 to form a roller assembly; the roller assembly is arranged in the rectangular cavity, the outer circumferential surface of the rollers 3.3 is in contact with the upper end surface of the slide base plate 3.1, and the outer side surface of the retainer 3.6 is in contact with the inner side surface of the slide side plate 3.4 to prevent the roller assembly from tilting when moving; the slide plate 3.2 is arranged at the upper part of the roller assembly, and the lower end surface of the slide plate 3.2 is in contact with the outer circumferential surface of the rollers 3.3; when the slide plate 3.2 moves horizontally relative to the slide base plate 3.1, the rollers 3.3 roll between the slide plate 3.2 and the slide base plate 3.1; see the accompanying drawings Figure 12 : The slide plate 3.2 is provided with slide plate sliding grooves 3.2.1 on both sides; see the accompanying drawings Figure 13 : The upper side surface of the slide side plate 3.4 is provided with slide side plate sliding rails 3.4.1, which are movably arranged in the slide plate sliding grooves 3.2.1 to movably connect the slide plate 3.2 and the slide base plate 3.1; the lower mold 2 is fixedly arranged on the upper end surface of the slide plate 3.2 to move in the horizontal direction with the slide plate 3.2;

[0031] See the accompanying drawings Figure 3 , 4 : When the molybdenum-rhenium alloy rod twisting and pressing processing die is working, the upper mold 1 is fixedly arranged at the lower part of the working head of the four-column hydraulic machine, and the slide 3 is fixedly arranged on the working table of the four-column hydraulic machine; the working head drives the upper mold 1 to move up and down; in the initial state, the upper mold 1 is at the highest position, the distance between the upper twisting and pressing plate 1.2 and the lower twisting and pressing plate 2.4 is the largest, the molybdenum-rhenium alloy rod 4 to be twisted and pressed is placed between the upper twisting and pressing plate 1.2 and the lower twisting and pressing plate 2.4, and the material supporting plate 1.1.2 of the upper mold plate 1.1 supports the molybdenum-rhenium alloy rod 4 to prevent it from falling; the working head of the hydraulic machine drives the upper mold 1 to move downward, the upper mold plate inclined surface 1.1.3 of the upper mold plate 1.1 is in contact with the lower mold plate inclined surface 2.1.1 of the lower mold plate 2.1, the upper mold plate inclined surface 1.1.3 pushes the lower mold plate inclined surface 2.1.1 to move to the right, that is, the upper mold 1 pushes the lower mold 2 to move in the horizontal direction on the slide 3 as a whole, so as to form a twisting and pressing combined motion between the upper twisting and pressing plate 1.2 and the lower twisting and pressing plate 2.4, that is, when the upper twisting and pressing plate 1.2 moves downward, the lower twisting and pressing plate 2.4 moves toward the upper twisting and pressing plate 1.2; at this time, the molybdenum-rhenium alloy rod 4 arranged between the upper twisting and pressing plate 1.2 and the lower twisting and pressing plate 2.4 rotates clockwise and moves downward at the same time, and under the pressure of the upper twisting and pressing plate 1.2 and the lower twisting and pressing plate 2.4, the diameter gradually decreases, realizing the twisting and pressing processing of the molybdenum-rhenium alloy rod;

[0032] The upper die plate inclined surface 1.1.3 and the lower die plate inclined surface 2.1.1 are both provided with arrayed and crossed oil storage grooves, and the oil storage grooves are coated with lubricating grease; when the upper die plate inclined surface 1.1.3 and the lower die plate inclined surface 2.1.1 slide relatively, the lubricating grease in the oil storage grooves enters the contact surface between the upper die plate inclined surface 1.1.3 and the lower die plate inclined surface 2.1.1, so that the wear between the upper die plate inclined surface 1.1.3 and the lower die plate inclined surface 2.1.1 is improved, and the service life of the rolling processing die is prolonged;

[0033] The drawings of the specification are as follows Figure 11 : A roller limiting slide rod 3.7 is movably arranged on the slide base end plate 3.5, and a spring is arranged between the roller limiting slide rod 3.7 and the slide base end plate 3.5; when the roller assembly moves to the left limit position during initial adjustment, the end of the retainer 3.6 abuts against the end of the roller limiting slide rod 3.7; the function of the roller limiting slide rod 3.7 is as follows: in theory, when the upper die 1 is at the uppermost position and the lower die 2 is at the leftmost position, the roller assembly is also at the leftmost position; when the upper die 1 is at the lowermost position and the lower die 2 is at the rightmost position, the roller assembly is also at the rightmost position; the roller assembly always reciprocates leftward and rightward within the designed movement range; however, in actual work, the roller assembly does not always reciprocate leftward and rightward within the designed movement range, but gradually deviates to the right side, and finally collides with the right slide base end plate 3.5 of the slide base 3, causing damage to the retainer 3.6; the reason is that, during the downward movement of the upper die 1, the lower end surface of the slide base plate 3.2 is always in contact with the roller 3.3, and the rotation of the roller 3.3 moves the roller assembly to the right side; when the upper die 1 moves to the lowermost position and then moves upward, because of the gap between the slide base side plate slide rail 3.4.1 and the slide base plate slide groove 3.2.1, the slide rail 1.1.1 of the upper die plate 1.1 drives the side plate slide groove 2.3.1, so that the lower end surface of the slide base plate 3.2 is separated from the roller 3.3; therefore, when the upper die 1 moves upward, the roller assembly cannot be completely and reliably returned, that is, after the roller assembly is returned, there is a slight deviation to the left; with the accumulation of the working time of the rolling processing die, the deviation of the roller assembly to the left becomes larger and larger, and finally causes the retainer 3.6 to collide with the slide base end plate, so that the retainer 3.6 is damaged; after the roller limiting slide rod 3.7 is arranged, even if the lower end surface of the slide base plate 3.2 is separated from the roller 3.3 during the upward movement of the upper die 1, the roller assembly can still be reliably returned under the action of the roller limiting slide rod 3.7, so that the problem that the roller assembly collides with the left slide base end plate 3.5 due to unreliable return is prevented.

[0034] The part not described in the present application is prior art.
