Description

Technical Field

[0001] The present invention relates to the technical field of fixing tables, and more particularly to a fixing table for forging workpieces. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape, and size. Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, since the complete metal flow lines are preserved, the mechanical properties of the forging are generally better than those of castings of the same material. During the processing of the forged workpiece, a fixed table is required to clamp the workpiece.

[0003] A Chinese patent with the authorization publication number CN211990756U discloses a forging workpiece fixing table, which can realize the rotation of the rotating shaft by rotating the rotating wheel, and the rotation of the pillar can drive the fixing table to rotate by the engagement of the worm and the ring gear, thereby realizing the adjustment of the workpiece processing angle.

[0004] Although this type of forging workpiece fixing table can adjust the workpiece processing angle to a certain extent, it has shortcomings in the fixing method, especially when processing circular workpieces. Due to the special shape of such workpieces, the existing fixing device is difficult to provide sufficient stability and firmness, resulting in displacement and shaking during the forging process, which not only affects the quality of the workpiece and increases the scrap rate, but also may pose a threat to the safety of the operator. In extreme cases, it may cause equipment damage, increase maintenance costs and downtime, and seriously affect production efficiency. Therefore, it is particularly important to improve the fixing method to meet the needs of workpieces of different shapes. Summary of the invention

[0032] The transmission groove 24, the slide bar 25, the transmission frame 26, the slide rail 27, the slide groove 28 and the slide bar are respectively provided in three groups and are dispersedly arranged in a ring shape.

[0033] First, place the annular forging 14 on the base 13, then start the motor 21 so that the output shaft 22 of the motor 21 drives the turntable 23 to rotate. The turntable 23 rotates, and the transmission groove 24 opened on the upper end surface causes the slide rod 25 slidably connected inside the transmission groove 24 to move. The slide rod 25 is fixedly connected to the clamping rod 29 slidably connected inside the slide groove 28 through the transmission frame 26 and the slide rail 27. Therefore, the clamping rod 29 will move synchronously and approach the annular forging 14 under the guidance of the slide groove 28, and fit tightly to preliminarily fix the annular forging 14.

[0034] The fixing mechanism also includes an outer clamping assembly 3 arranged outside the axial fixing assembly 2. The upper end surface of the support platform 13 is provided with two sets of second slide grooves 31. The two sets of second slide grooves 31 are symmetrically arranged on both sides of the first slide groove 28 and are inclined.

[0035] The two sets of slide grooves 31 are both slidably connected with slide rods 32 , and the upper end surface of the slide rods 32 is fixedly mounted with a clamping plate 33 . The lower ends of the two sets of slide rods 32 extend to the inside of the slide rail 27 and are slidably connected with the slide rail 27 .

[0036] The slide rail 27 is synchronously displaced inward, and the slide rod 2 32 slidably connected in the slide rail 27 will synchronously follow the slide rail 27 to displace, and the slide rod 2 32 is slidably connected to the slide groove 2 31, and the slide groove 2 31 is inclined to the axis of the annular forging 14. Therefore, under the joint action of the slide rail 27 and the slide groove 2 31, the slide rod 2 32 will drive the clamp plate 1 33 to displace, and the two groups of clamp plates 1 33 are both tightly attached to the annular forging 14, and the three groups of outer clamp components 3 cooperate with each other for fixation.

[0037] The axial fixing component 2 also includes an inner support component 4 arranged inside the outer clamping component 3, and the inner support component 4 includes a connecting shaft 41 fixedly installed at the lower end of two sets of sliding rods 32, a top block 42 is arranged on the outer side of the sliding rail 27, and a connecting rod 43 is rotatably connected between the two sets of connecting shafts 41 and the top block 42.

[0038] A slide groove 3 46 is provided on the upper end surface of the base 13, and the slide groove 3 46 is arranged on the inner side of the slide groove 1 28. A vertical rod 45 is slidably connected inside the slide groove 3 46, and a transmission rod 44 is fixedly installed between the vertical rod 45 and the top block 42. A clamping plate 2 47 is provided on the inner side of the circular forging 14, and the clamping plate 2 47 is fixedly connected to the vertical rod 45.

[0039] A connecting rod 43 is rotatably connected between the connecting shaft 41 fixedly installed at the lower end of the two sets of sliding rods 32 and the top block 42. Therefore, when the two sets of sliding rods 32 are displaced toward the annular forging 14, the top block 42 will move outward, and drive the vertical rod 45 to move toward the annular forging 14 inside the sliding groove 3 46 through the transmission rod 44, so that the clamp plate 2 47 is tightly attached to the annular forging 14.

[0040] The fixing mechanism also includes a coordination component 5 arranged inside the clamp rod 29, the coordination component 5 includes a groove 51 opened on the inner wall of the clamp rod 29, a fixing block 53 is arranged inside the groove 51, a force plate 52 is fixedly installed at one end of the fixing block 53, and a spring 54 is fixedly installed between the force plate 52 and the inner wall of the groove 51.

[0041] A guide cavity 55 and two groups of receiving cavities 56 are formed inside the clamp rod 29 . The two groups of receiving cavities 56 are arranged on both sides of the clamp rod 29 and are connected to the groove 51 through the guide cavity 55 .

[0042] The interior of the storage cavity 56 is slidably connected with an insert plate 57 , and the ends of the clamping plates 33 on both sides of the clamping rod 29 are both provided with slots 59 .

[0043] A memory alloy 58 is slidably connected inside the storage cavity 56 . One end of the memory alloy 58 extends to the inside of the groove 51 and is fixedly connected to the fixing block 53 . The other end of the memory alloy 58 extends to the inside of the storage cavity 56 and is fixedly connected to the insert plate 57 .

[0044] When the clamp rod 29 is in close contact with the annular forging 14, the force-bearing plate 52 will be forced to retract toward the inside of the groove 51, and drive the Y-shaped memory alloy 58 to slide inside the guide cavity 55 through the fixed block 53, so that the plug plate 57 fixedly installed at the other end of the memory alloy 58 extends from the inside of the storage cavity 56 and is inserted into the slot 59 on the two adjacent groups of clamp plates 33, thereby connecting the clamp rod 29 and the two groups of clamp plates 33 into a whole, thereby increasing the stability of the annular forging 14.

[0045] There are deficiencies in the fixing method, which is particularly evident when processing circular ring-shaped workpieces. Due to the special shape of such workpieces, the existing fixing devices are difficult to provide sufficient stability and firmness, resulting in displacement and shaking during the forging process. This not only affects the quality of the workpiece and increases the scrap rate, but may also pose a threat to the safety of the operator. In extreme cases, it may cause equipment damage, increase maintenance costs and downtime, and seriously affect production efficiency. Therefore, this scheme sets up a special fixing mechanism and uses the axial fixing component 2 to ensure the stability of the center of gravity of the circular ring forging 14. At the same time, it cooperates with the outer clamping component 3 and the inner support component 4 for bidirectional fixing, which effectively prevents the displacement and shaking of the workpiece during the processing, greatly improves the processing accuracy and safety, and at the same time, by setting the coordination component 5, the clamping rod 29 and the clamping plate 33 are connected into a whole, which enhances the integrity of the structure and significantly improves the stability and operating accuracy of the equipment. It not only effectively prevents the displacement and shaking of the workpiece during the processing, but also extends the service life of the equipment, ensuring higher processing quality and safety.

[0046] Usage method: First, place the circular ring forging 14 on the support 13, then start the motor 21, so that the output shaft 22 of the motor 21 drives the turntable 23 to rotate, and the turntable 23 rotates, and the transmission groove 24 provided on the upper end surface causes the slide bar 25 slidably connected inside the transmission groove 24 to move, and the slide bar 25 is fixedly connected to the clamping rod 29 slidably connected inside the slide groove 28 through the transmission frame 26 and the slide rail 27, so that the clamping rod 29 will move synchronously, and under the guidance of the slide groove 28, it will approach the circular ring forging 14 and cling to it, so as to preliminarily fix the circular ring forging 14;

[0047] Secondly, the slide rail 27 is synchronously displaced inward, and the slide rod 2 32 slidably connected in the slide rail 27 will synchronously follow the slide rail 27 to displace, and the slide rod 2 32 is slidably connected with the slide groove 2 31, and the slide groove 2 31 is inclined to the axis of the circular forging 14. Therefore, under the joint action of the slide rail 27 and the slide groove 2 31, the slide rod 2 32 drives the clamping plate 1 33 to displace, and the two groups of clamping plates 1 33 are tightly attached to the circular forging 14, and the three groups of outer clamping components 3 cooperate with each other to fix;

[0048] The connecting rod 43 is rotatably connected between the connecting shaft 41 fixedly installed at the lower end of the two sets of sliding rods 32 and the top block 42, so that the top block 42 will move outward when the two sets of sliding rods 32 move toward the annular forging 14, and drive the vertical rod 45 to move toward the annular forging 14 inside the sliding groove 3 46 through the transmission rod 44, so that the clamping plate 47 is tightly attached to the annular forging 14;

[0049] When the clamp rod 29 is in close contact with the annular forging 14, the force-bearing plate 52 will be forced to retract toward the inside of the groove 51, and drive the Y-shaped memory alloy 58 to slide inside the guide cavity 55 through the fixed block 53, so that the plug plate 57 fixedly installed at the other end of the memory alloy 58 extends from the inside of the storage cavity 56 and is inserted into the slot 59 on the two adjacent groups of clamp plates 33, thereby connecting the clamp rod 29 and the two groups of clamp plates 33 into a whole, thereby increasing the stability of the annular forging 14.

[0050] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
