Description

Technical Field

[0001] This utility model relates to the field of drawing machine technology, specifically to a profile drawing device. Background Technology

[0002] The main reason for setting a mandrel (equivalent to the die head in this application) during tube drawing is to control the size and shape of the tube, reduce friction, and improve the stability of the drawing process.

[0003] First, setting a mandrel can control the size and shape of the drawn material. The mandrel plays a supporting and positioning role in the drawing process, ensuring that the tube maintains the correct size and shape during the drawing process. The use of mandrels is especially important for thin-walled tubes, as it can reduce the deformation of the tube during the drawing process. Secondly, setting a mandrel can reduce friction. The friction between the mandrel and the inner wall of the tube is one of the main resistances in the drawing process. By rationally designing the geometry and material of the mandrel, friction can be reduced, and drawing efficiency and quality can be improved. Secondly, setting a mandrel can improve the stability of the drawing process. The design and selection of the mandrel directly affect the stability of the drawing process because the mandrel can move freely along the axial direction. By adaptively adjusting, it can reduce the problem of uneven distribution of friction force, thereby improving the stability of the drawing process.

[0004] Based on the above, the mandrel plays a crucial role in the drawing process of tubular profiles. However, in practice, tubular profiles are heavy and long, and both the mandrel and mandrel (equivalent to the stabilizing rod in this application) are made of metal and are very heavy, making the process of threading the tubular profile to be drawn onto the mandrel and mandrel quite cumbersome. Therefore, we propose a profile drawing device. Utility Model Content

Each adjustment groove is disposed on a first support by fasteners. The bottom of each first support is mounted on a first frame.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 6 This utility model provides a technical solution: a profile drawing device, including a first frame 1, with a forming device at one end of the first frame 1. The forming device includes a mold base 11, in which a drawing die 29 is installed. The mold base 11 is mounted on a second frame 10. To make the overall structure more stable, the second frame 10 is connected to the first frame 1. In actual use, the profile to be drawn needs to pass through the inside of the drawing die 29. At this time, there is a huge friction between the profile and the drawing die 29. Therefore, a collection pool 13 is provided on the side of the mold base 11 near the first frame 1. The collection pool 13 can be used to place lubricating powder. Alternatively, an oil nozzle 12 is provided above the drawing die 29. The oil nozzle 12 is connected to an oil supply pump through a pipe. The lubricating oil sprayed from the oil nozzle 12 will drip onto the profile, and the dripping lubricating oil can be collected in the collection pool 13. Waste oil is collected through a pipe on the side of the collection pool 13.

[0025] The other side of the forming device is provided with a drawing mechanism, which includes a third frame 25. In order to make the overall structure more stable, the third frame 25 is connected to the second frame 10. A drawing carriage 27 is provided on the top of the third frame 25. The track wheels on both sides of the bottom of the drawing carriage 27 are placed on the edge of the third frame 25, so that the drawing carriage 27 can travel back and forth along the third frame 25. In order to pull the pulling carriage 27, a drive zipper 31 is provided in the third frame 25. Both ends of the drive zipper 31 are provided with third drive sprockets 30, which are mounted on support shafts. Both ends of the support shafts are rotatably connected to the bottom of the third frame 25. The hooks on the pulling carriage 27 are connected to the drive zipper 31. One of the support shafts is connected to the second drive device 26. The second drive device 26 is a combination of a drive motor and a reducer. In actual use, the drive motor drives the support shaft to rotate through the reducer, thereby driving the pulling carriage 27 to move towards the mold base 11. After the pulling carriage 27 clamps one end of the tube profile, it is pulled back under the drive of the drive zipper 31.

[0026] The composition of the first frame 1 will be described in detail below, such as... Figure 1 and Figure 3 As shown, a planar conveyor 20 is mounted on top of the first frame 1, i.e., the planar conveyor 20 is a planar conveyor belt. A drive trolley is mounted above the planar conveyor 20, and the drive trolley travels on the first frame 1 from both sides of its bottom. The structure of the drive trolley is as follows. Figure 3 and Figure 4 As shown, the driving trolley includes a U-shaped frame 22 located above the planar conveyor 20. The opening of the U-shaped frame 22 faces downward. At least two track wheels 4 are rotatably provided on the bottom of both sides of the U-shaped frame 22. The track wheels 4 are respectively placed on the two side edges of the first frame 1, so that the U-shaped frame 22 can travel back and forth along the first frame 1 by means of the track wheels 4. The side of the drive trolley closest to the molding device is connected to the stabilizer bar 19. The stabilizer bar 19 is positioned corresponding to the molding device, and its end is equipped with a die head 18 that matches the molding device. Both the die head 18 and the stabilizer bar 19 are placed on the planar conveyor 20. The stabilizer bar 19 and the drive trolley are specifically installed as follows: Figure 4 As shown, an L-bracket 32 ​​is installed in the middle of the U-shaped frame 22. The L-bracket 32 ​​extends toward the mold base 11. The bottom of the L-bracket 32 ​​is connected to the end of the stabilizer bar 19 away from the mold head 18. In this way, when the trolley moves along the first frame 1, the U-shaped frame 22 can drive the stabilizer bar 19 to move toward the mold base 11 or pull the stabilizer bar 19 away from the mold base 11.

[0027] A chain drive device is provided below the first frame 1. The chain drive device is connected to the drive trolley. Specifically, L-shaped frames 6 are provided at both ends of the U-shaped frame 22. The two ends of the U-shaped frame 22 are connected to the chain drive device through the L-shaped frames 6. The chain drive device is used to drive the U-shaped frame 22 to move along the first frame 1. Figure 4 indivual Figure 5As shown, the chain drive device includes drive shafts 2 distributed at both ends below the first frame 1 and drive chains 5 located on both sides below the first frame 1. The two ends of the drive shafts 2 are rotatably connected to the first frame 1. First drive sprockets 3 are also provided at both ends of the drive shafts 2. Both ends of the drive chains 5 are located on the first drive sprockets 3. Due to the long span of the drive chains 5, to prevent the middle of the drive chains 5 from sinking and deforming, multiple support sprockets 7 are provided inside the drive chains 5. The support sprockets 7 are all rotatably mounted on the first frame 1. It should be noted that the bottom of the L-shaped frame 6 is specifically connected to the drive chains 5.

[0028] One end of the chain drive device is connected to the first drive device 24. Specifically, a drive shaft 2 is connected to the first drive device 24. The first drive device 24 is the same as the second drive device 26, which is a combination of a drive motor and a reducer. In use, the drive motor drives the drive shaft 2 to rotate through the reducer. Specifically, when the first drive device 24 rotates, it can drive the drive shaft 2 to rotate. The drive shaft 2 can drive the drive chain 5 to rotate. Since there are two drive chains 5 and they are symmetrically distributed under the first frame 1, the two drive chains 5 simultaneously drive the U-shaped frame 22 to move along the first frame 1, so that the forces at both ends of the U-shaped frame 22 are balanced, and the reciprocating motion of the U-shaped frame 22 is more stable.

[0029] Based on the above embodiments, this application proposes that the drawing device works as follows: 1. In the initial state, the drive trolley (U-shaped frame 22) is driven by the drive chain 5 and stays at the end of the flat conveyor 20 away from the forming device, so that the space between the die head 18 and the forming device (drawing die 29) can be used to place the tube profile to be drawn. 2. For example Figure 1 and Figure 4 As shown by arrow A, the tube profile to be drawn is placed on the flat conveyor 20. At this time, the tube profile is located between the drawing die 29 and the die head 18. Then, the first drive device 24 and the flat conveyor 20 are controlled to rotate together. At this time, the end of the tube profile with the smaller diameter can move towards the drawing die 29 under the drive of the flat conveyor 20. When the end of the tube profile with the smaller diameter is placed in the drawing die 29, the end of the tube profile can be limited and fixed by the drawing die 29. At this time, the flat conveyor 20 stops moving. After the tubular profile is fixed by the drawing die 29, the die head 18 continues to move forward under the drive of the U-shaped frame 22. Therefore, the die head 18 will enter the interior of the tubular profile from the end. Since the length of the stabilizer bar 19 is longer than the length of the tubular profile, the stabilizer bar 19 pushes the die head 18 into the end of the tubular profile. 3. At this time, the second drive device 26 can be controlled to operate and drive the drawing carriage 27 to move closer to the mold base 11. When the drawing carriage 27 moves to the side of the mold base 11, the hydraulic clamp at the end of the drawing carriage 27 clamps one end of the tube profile. Then, the second drive device 26 can be controlled to reverse so that it drives the drawing carriage 27 to draw the tube profile. The die head 18 and the drawing die 29 cooperate to draw the tube profile into shape. 4. After the tube profile is drawn once, the tube profile is removed from between the die head 18 and the drawing die 29. Then, the die head 18 returns to the initial position under the drive chain 5. Then, the tube profile is placed on the flat conveyor 20 and the above process is repeated.

[0030] Furthermore, in order to position the tubular profile when it is placed on the flat conveyor 20, multiple baffles 15 are provided on one side of the tubular profile. Each baffle 15 is provided with a vertical support screw 16 on the side away from the tubular profile. The other end of each support screw 16 is movably disposed in a second support 17 and the two are pre-tightened by a fastener. The fastener is a nut threaded on the support screw 16. Tightening the nut can fix the support screw 16. The bottom of each second support 17 is mounted on the first frame 1. On the other side of the tubular profile, there are multiple strip arms 9 perpendicular to the baffle 15. Each strip arm 9 has an adjustment groove 33 at the end away from the tubular profile. Each adjustment groove 33 is set on the first support 8 by fasteners. The fasteners are bolts. The bolts are placed in the adjustment grooves 33 and installed on the first support 8 by nuts. The bottom of each first support 8 is installed on the first frame 1. like Figure 4 As shown, the space formed between the strip arm 9 and the baffle 15 is used to place the tubular profile. It should be noted that one side of the strip arm 9 is the feeding side, and the top of the end of the strip arm 9 is a sliding inclined surface 14. When the tubular profile is placed on the strip arm 9 (as shown), Figure 4 (As shown by the dashed line in the middle), the tube profile can then roll along the sliding inclined plane 14 to the space between the strip arm 9 and the baffle 15. At this time, the end of the tube profile corresponds to the die head 18, and the tube profile can be positioned.

[0031] However, in order to ensure that the stabilizer bar 19 is always aligned with the end of the tubular profile, arc-shaped guide plates 21 are provided on both sides of the stabilizer bar 19. The space between the arc-shaped guide plates 21 is used to limit the stabilizer bar 19. The two arc-shaped guide plates 21 are mounted on the third support 28 through the support arm 23 on the side that is far away from each other. Each third support 28 is mounted on the first frame 1.

[0032] Based on the above embodiments, it should be further explained that a counterweight can be set on the top of the U-shaped frame 22, which can make the reciprocating motion of the U-shaped frame 22 more stable. During its reciprocating motion, the U-shaped frame 22 will not contact the support screw 16 or the strip arm 9, and the arc guide plate 21 will not contact the L bracket 32.

[0033] Based on the above embodiments, further optimization is possible. Similar to the drive chain 5, the drive zipper 31 is also very long. To prevent the drive zipper 31 from sinking and deforming, such as... Figure 6 As shown, multiple support wheels are provided inside the drive zipper 31, and these support wheels are rotatably mounted below the third frame 25.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
