Description

Technical Field

[0001] The present invention is a drawing device for special alloy materials, belonging to the field of alloy material processing. Background Art

[0002] A metal raw material is made to pass through a die hole with a specific shape and size by applying a tensile force, thereby forming a product with the required shape (such as a tube, rod, profile, or wire). This forming process is called drawing and is one of the key technologies for manufacturing these metal products. Special alloy materials are a type of metal material with special properties, usually composed of two or more metal elements, and sometimes non-metal elements are also added to obtain specific physical, chemical, or mechanical properties. These alloys exhibit excellent properties under extreme conditions such as high temperature, high pressure, and corrosive environments, and thus are widely used in fields such as aerospace, nuclear industry, petrochemical industry, and automotive manufacturing. In the production of special alloy materials, drawing is also commonly used. Currently, during the process of drawing special alloy materials, the movable end of a hydraulic cylinder is connected to one end of the special alloy material, and then the hydraulic cylinder is controlled to contract, thereby providing power for drawing the special alloy material. The above processing method is a common processing technology for drawing special alloy materials. However, this drawing method is limited by the stroke range of the hydraulic cylinder. Using a hydraulic cylinder with a short stroke requires frequent disassembly and assembly of the connection structure between the movable end of the hydraulic cylinder and the end of the special alloy material, which is time-consuming and laborious and affects work efficiency. While using a hydraulic cylinder with a long stroke results in a longer length of the hydraulic cylinder, thus increasing the floor area occupied. Summary of the Invention

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a drawing device for special alloy materials to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention is realized through the following technical solutions: A drawing device for special alloy materials includes a bottom frame. On one side of the upper surface of the bottom frame, a reduction gearbox is installed. On one side of the reduction gearbox, a motor is installed. The output shaft of the motor is connected to the input end of the reduction gearbox. The output end of the reduction gearbox is installed with a small sprocket. On the upper side of the bottom frame, away from the reduction gearbox, there is a winding shaft for winding a steel wire rope. Both ends of the winding shaft are sleeved with supports that are rotationally connected to the winding shaft. The lower ends of the supports are fixedly connected to the bottom frame. Both ends of the winding shaft are sleeved with limit discs that are fixedly connected to the winding shaft for restricting the position of the steel wire rope. One end of the winding shaft is sleeved with a large sprocket that is fixedly connected to the winding shaft. The large sprocket is arranged between the support and the limit disc. The large sprocket is connected to the small sprocket through a chain. On the side of the winding shaft facing away from the motor, there is a dispersing member for reducing the force acting on the winding shaft.

[0005] Specifically, the dispersing member includes a round rod. A round rod is provided on the side of the winding shaft away from the motor. The round rod is arranged parallel to the winding shaft. Both ends of the round rod are sleeved with second bearings. Positioning sleeves are sleeved on both of the second bearings. The opposite surfaces of the two positioning sleeves are both open. A support plate is fixedly connected to the lower position of the outer surface of the positioning sleeve. The lower end of the support plate is fixedly connected to a connecting plate. A cross plate is provided on the side of the bottom frame away from the round rod. The cross plate is connected to the bottom frame by a plurality of bolts. The end of the connecting plate away from the support plate is fixedly connected to an ear plate. The ear plate is connected to the cross plate by a fastener formed by a connecting screw and a first nut. Two first bearings that respectively rollingly contact the limiting discs are sleeved on the round rod. Adjusting members for restricting the relative positions of the round rod and the first bearings are installed on both of the support plates.

[0006] Specifically, the adjusting member includes a U-shaped frame. U-shaped frames are sleeved on both of the first bearings. The U-shaped frame is arranged on the lower side of the first bearing. A vertical plate is installed on the lower surface of the U-shaped frame. Transverse holes are opened on the opposite surfaces of both of the support plates. Screws are inserted into the transverse holes. One end of the screw is connected to the vertical plate. Second nuts that are threadedly connected to the screw are provided on both sides of the transverse hole along the length direction of the screw. A guide rod that is arranged parallel to the screw is provided on the lower side of the screw. Guide holes are opened on the opposite surfaces of both of the support plates. The guide rod penetrates through the guide hole. One end of the guide rod is connected to the vertical plate.

[0007] Specifically, a first positioning hole is opened at the upper position of one side surface of the vertical plate. A second positioning hole is opened at the lower position of one side surface of the vertical plate. One end of the screw is installed in the first positioning hole. One end of the guide rod is installed in the second positioning hole.

[0008] Specifically, a plurality of threaded holes are annularly and equidistantly opened on the outer surface of the open end of the positioning sleeve. The threaded holes are arranged along the radial direction of the positioning sleeve. Blocking screws for restricting the second bearing in the positioning sleeve are threadedly connected in the threaded holes.

[0009] Specifically, first through holes are opened at both ends of the cross plate. A second through hole that is aligned with the first through hole is opened on one side surface of the ear plate. One end of the connecting screw passes through the channel formed by the first through hole and the second through hole and is then threadedly connected to the first nut.

[0010] Specifically, through holes are opened at the upper positions of the opposite surfaces of both of the supports. Both ends of the winding shaft respectively penetrate through the two through holes. A bearing seat that is concentric with the through hole is provided outside the through hole. The bearing seat is connected to the support by a plurality of screws. The bearing seat is sleeved on the end of the winding shaft and is rotatably connected to the bearing seat.

[0011] The beneficial effects of the present invention:

[0012] 1. After one end of the steel wire rope wound on the reel is connected to one end of the special alloy material, the motor is controlled to work. After deceleration by the reduction gear box, the small sprocket rotates, and the small sprocket drives the large sprocket to rotate through the chain. The large sprocket reels the steel wire rope on the reel through the reel, thereby providing power for drawing the special alloy material. Due to the long length of the steel wire rope, when drawing the long special alloy material, there is no need to frequently disassemble and assemble the connection structure between the steel wire rope and the special alloy material, which is conducive to improving work efficiency and reducing the site occupation area.

[0013] 2. Use connecting screws and first nuts to connect the ear plate and cross plate, and use bolts to connect the cross plate and bottom frame, so that under the restriction of the connecting plate and the support plate, the positions of the two positioning sleeves are restricted, so that the second bearings in the two positioning sleeves are respectively mounted on the two ends of the round rod, and the two first bearings on the round rod are respectively in rolling contact with the two limit plates, so that the force of the wire rope acting on the winding shaft during the winding process will act on the bottom frame through the first bearing, round rod, connecting plate, cross plate and other components, so that part of the reaction force acting on the winding shaft is dispersed on the bottom frame, reducing the load on the connection part of the winding shaft and the support, improving the stability of the structure, and reducing the strength requirement of the connection part of the winding shaft and the support.

[0014] 3. After the second bearing is mounted on the round rod, the positioning sleeve is mounted on the second bearing, and then blocking screws are screwed into the multiple threaded holes on the positioning sleeve. The positioning sleeve and the blocking screws cooperate with each other to limit the relative position of the second bearing and the round rod.

[0015] 4. Adjust the position of the first bearing along the round rod. At this time, the first bearing drives the screw to move along the transverse hole through the structure formed by the U-shaped frame and the vertical plate. At the same time, the guide rod moves along the guide hole. The guide rod and the screw cooperate with each other to prevent the U-shaped frame from rotating. When the worn area of the outer ring surface of the first bearing is offset from the limit plate, the two second nuts on the screw are used to limit the relative position of the screw and the support plate, so that the relative position of the first bearing and the limit plate can be adjusted, which is conducive to uniform wear of the first bearing, extending the service life of the first bearing, and improving the utilization rate of the first bearing.

A winding shaft 11 for winding a wire rope is provided on the side of the upper side of the bottom frame 1 away from the reduction gear box 13, and both ends of the winding shaft 11 are sleeved with a support 20 rotatably connected to the winding shaft 11, and the lower end of the support 20 is connected and fixed to the bottom frame 1, and through holes are opened at the upper positions of the opposing surfaces of the two supports 20, and two through holes are respectively passed through at both ends of the winding shaft 11, and a bearing seat 21 arranged concentrically with the through hole is provided on the outer side of the through hole. The bearing seat 21 is connected to the support 20 by a plurality of screws, and the bearing seat 21 is sleeved on the end of the winding shaft 11 and is rotatably connected to the bearing seat 21, and the bearing seat 21 realizes the rotation connection between the winding shaft 11 and the support 20.

[0027] See Figure 1 and Figure 2 The large sprocket 22 is connected to the take-up shaft 11 by the chain 14, so that the wire rope can be wound on the take-up shaft 11 and the small sprocket 15 is connected to the take-up shaft 11.

[0028] See Figures 1-5 A round rod 2 is provided on the side of the winding shaft 11 facing away from the motor 12. The round rod 2 is arranged parallel to the winding shaft 11. Second bearings 30 are sleeved on both ends of the round rod 2. Positioning sleeves 7 are sleeved on the two second bearings 30. The opposite surfaces of the two positioning sleeves 7 are open. The outer surface of the open end of the positioning sleeve 7 is annular and equidistantly provided with a plurality of threaded holes 27. The threaded holes 27 are arranged along the radial direction of the positioning sleeve 7. The threaded holes 27 are connected with a blocking screw 8 for limiting the second bearing 30 in the positioning sleeve 7. After the second bearing 30 is sleeved on the round rod 2, the positioning sleeve 7 is sleeved on the second bearing 30, and then the blocking screws 8 are screwed into the multiple threaded holes 27 on the positioning sleeve 7, and then the positioning sleeve 7 and the blocking screw 8 cooperate with each other to limit the relative position of the second bearing 30 and the round rod 2.

[0029] Refer to Figures 1-6 , a support plate 6 is fixedly connected to the lower position of the outer surface of the positioning sleeve 7. A connecting plate 19 is fixedly connected to the lower end of the support plate 6. A cross plate 16 is provided on one side of the bottom frame 1 away from the round rod 2. The cross plate 16 is connected to the bottom frame 1 through a plurality of bolts. One end of the connecting plate 19 away from the support plate 6 is fixedly connected with an ear plate 17. The ear plate 17 is connected to the cross plate 16 through a fastener formed by a connecting screw 18 and a first nut 24. That is, first through holes 25 are formed at both ends of the cross plate 16. A second through hole 26 aligned with the first through hole 25 is formed on one side surface of the ear plate 17. One end of the connecting screw 18 passes through the channel formed by the first through hole 25 and the second through hole 26 and is threadedly connected to the first nut 24. Two first bearings 9 respectively in rolling contact with the limiting disks 10 are sleeved on the round rod 2. The ear plate 17 and the cross plate 16 are connected by the connecting screw 18 and the first nut 24, and the cross plate 16 and the bottom frame 1 are connected by bolts. Thus, under the restriction of the connecting plate 19 and the support plate 6, the positions of the two positioning sleeves 7 are restricted, so that the second bearings 30 in the two positioning sleeves 7 are respectively sleeved on both ends of the round rod 2, and the two first bearings 9 on the round rod 2 are respectively in rolling contact with the two limiting disks 10. Furthermore, the force acting on the winding shaft 11 during the winding process of the steel wire rope will act on the bottom frame 1 through components such as the first bearing 9, the round rod 2, the connecting plate 19, and the cross plate 16, realizing the dispersion of a part of the reaction force acting on the winding shaft 11 on the bottom frame 1, reducing the load on the connecting part of the winding shaft 11 and the support 20, improving the stability of the structure, and reducing the strength requirement for the connecting part of the winding shaft 11 and the support 20.

[0030] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 7, U-shaped frames 23 are sleeved on both of the two first bearings 9. The U-shaped frames 23 are arranged on the lower sides of the first bearings 9. Vertical plates 3 are installed on the lower surfaces of the U-shaped frames 23. Transverse holes 28 are formed in the opposite surfaces of the two support plates 6. Screws 5 are inserted into the transverse holes 28. Second nuts 31 threadedly connected to the screws 5 are arranged on both sides of the transverse holes 28 along the length direction of the screws 5. Guide rods 4 arranged parallel to the screws 5 are provided below the screws 5. Guide holes 29 are formed in the opposite surfaces of the two support plates 6. The guide rods 4 penetrate through the guide holes 29. First positioning holes 32 are formed in the upper positions of one side surfaces of the vertical plates 3. Second positioning holes 33 are formed in the lower positions of one side surfaces of the vertical plates 3. One ends of the screws 5 are installed in the first positioning holes 32, and one ends of the guide rods 4 are installed in the second positioning holes 33, thus completing the connection and fixation of the screws 5, the guide rods 4 and the vertical plates 3. Adjust the positions of the first bearings 9 along the round rods 2. At this time, the structures formed by the U-shaped frames 23 and the vertical plates 3 drive the screws 5 to move along the transverse holes 28, and at the same time the guide rods 4 move along the guide holes 29. The guide rods 4 and the screws 5 cooperate with each other to prevent the U-shaped frames 23 from rotating. When the worn areas on the outer ring surfaces in the first bearings 9 are staggered with the limit discs 10, the relative positions of the screws 5 and the support plates 6 are restricted by the two second nuts 31 on the screws 5, so as to adjust the relative positions of the first bearings 9 and the limit discs 10, which is beneficial to evenly wear the first bearings 9, extend the service lives of the first bearings 9 and improve the utilization rates of the first bearings 9.
