Description

Technical Field

[0001] The present application relates to the technical field of manufacturing auxiliary equipment, and in particular to a T-shaped structural member correction device. Background Art

[0002] In mechanical design and manufacturing, there are often T-shaped structural parts welded together from two plates. During welding, the stress causes the T-shaped structural parts to be non-vertical. In addition, due to different welding processes, the deviation angle may be large or small. The structure needs to be calibrated after welding before it can be used normally or shipped out of the factory. There are many ways to calibrate the structure.

[0003] Conventional shaping methods use hammering and flame shaping. However, for some stainless steel products with relatively high requirements, hammering and flame shaping of the weld surface are generally prohibited. This shaping method will have an adverse effect on the welding quality and reduce the strength and service life of the structure. For such parts, only low-stress processing methods such as extrusion shaping can be used. The existing extrusion shaping device is inconvenient to fix the workpiece and the shaping efficiency is low. Summary of the Invention

[0004] In order to improve the correction efficiency of T-shaped structural members, the present application provides a T-shaped structural member correction device.

[0005] The present application provides a T-shaped structural member correction device that adopts the following technical solution: A T-shaped structural member correction device includes an upper die, an upper die, a lower die, a mounting plate and a base, wherein the upper die is fixed below the upper die and is mounted on a press when in use, the mounting plate is fixed above the base, and the lower die is arranged above the mounting plate, the lower die is in the shape of a vertical plate, and is provided with a placement opening for placing T-shaped or L-shaped workpieces, the placement opening is located directly below the upper die at the corresponding position, and the placement opening has an opening angle of 85°-88°, and there are three lower die molds, which are evenly spaced on the mounting plate.

[0006] By adopting the above technical solution, a T-shaped workpiece or an L-shaped workpiece is placed at the placement opening so that the side of the workpiece that is aligned greater than 90° faces upward, and then the upper pressing tire and the upper pressing die are driven downward by the press. The bottom of the upper pressing die is facing the welding part of the workpiece. During the downward pressing process, the workpiece can be squeezed to a vertical state, and the workpiece will not slide sideways, making processing more convenient. The lower tire molds are evenly arranged to provide stable support force, ensuring that the workpiece is evenly stressed when placed, thereby improving the correction effect.

[0007] Preferably, the cross-section of the upper die is T-shaped, the bottom of the upper die is provided with rounded corners, and a number of symmetrically distributed reinforcing ribs for improving strength are fixed on both sides of the upper die. The reinforcing ribs on the same side are distributed at equal intervals, and mounting holes for fixing the upper die are provided on both sides of the upper end of the upper die.

[0008] By adopting the above technical solution, when the upper die contacts the workpiece, the rounded corners can increase the contact area between the upper die and the workpiece, reduce the impact on the weld, and concentrate the pressure on the lower end of the upper die through the inverted triangle structure, so that the correction part is subjected to appropriate pressure.

[0009] Preferably, a first concave groove is provided at the bottom of the upper tire pressure, and the upper end of the upper pressure mold is fixed to the inner side of the first concave groove by bolts to prevent the upper pressure mold from shifting. A second concave groove is provided on the upper surface of the base, and the bottom of the mounting plate is fixed to the inner side of the second concave groove by bolts to prevent the mounting plate from shifting.

[0010] By adopting the above technical solution, the upper die is limited by the first concave groove, and the mounting plate is limited by the second concave groove. When the workpiece is corrected, the positions of the upper die and the lower die will not change, and the structure is more stable, thereby improving the accuracy of the correction and improving the correction effect.

[0011] Preferably, the upper surface of the mounting plate is provided with four vertical rods distributed symmetrically about the center, and two side plate slide rails distributed along the length direction of the upper pressing mold are fixed on the vertical rods, and the two side plate slide rails are symmetrically distributed, two sliding holes are respectively provided at both ends of the lower tire mold, and the lower tire mold is slidably set on the side plate slide rails through the two sliding holes, and two pin holes are provided on the side plate slide rails, and the two pin holes are respectively located on both sides of the middle lower tire mold, and fixing pins are inserted in the pin holes to prevent the lower tire mold in the middle position from moving to both sides, an ear plate is fixed to one end of the lower tire mold, a rotating hole is provided on the ear plate located in the middle position, and a two-way threaded rod is rotatably connected to the rotating hole, threaded holes are provided on the two ear plates located at both ends, and are threadedly connected to the two-way threaded rod through the threaded holes, and a rotating handle is fixed to one end of the two-way threaded rod.

[0012] By adopting the above technical solution, the operator can turn the rotating handle to drive the bidirectional threaded rod to rotate. At this time, the lower tire mold located in the middle position is limited by the fixed pins on both sides and will not move to the sides. The two lower tire molds on both sides will move symmetrically under the drive of the bidirectional threaded rod. It can not only adjust the distance between the two lower tire molds, but also ensure that the two lower tire molds are always in a symmetrical state. According to the width of the workpiece, the distance between the two lower tire molds on both sides is adjusted to the distance that just places the workpiece. It can process workpieces of different widths, thereby expanding the scope of application of the device.

[0013] Preferably, the height dimension of the side panel slide rail is smaller than the height dimension of the slide hole, a spring hole is opened on the upper inner wall of the slide hole, and a thrust spring is arranged in the spring hole, a top cover is provided at the end of the thrust spring away from the spring hole, and the lower end of the top cover is against the upper surface of the side panel slide rail, and a gap is provided between the bottom of the lower tire mold and the mounting plate.

[0014] By adopting the above technical solution, the lower tire mold is not only slidably set on the side panel slide rail, but also can move slightly up and down along the side panel slide rail. Under the support of the thrust spring, the lower tire mold moves upward, and its bottom is separated from the mounting plate. During movement, no friction is generated between the lower tire mold and the mounting plate. When correcting the workpiece, when the upper pressure mold is pressed downward, the lower tire mold will move downward and compress the thrust spring, so that the bottom of the lower tire mold is against the mounting plate. The mounting plate provides support force for correcting the workpiece, which can prevent the side panel slide rail from deformation, increase the service life of the side panel slide rail, thereby extending the service life of the device and reducing the maintenance requirements of the device.

[0015] Preferably, a graphite coating is provided on the lower surface of the top cover to reduce the friction between the top cover and the upper surface of the side panel slide rail.

[0016] By adopting the above technical solution, the lower tire mold will be affected by the friction between the top cover and the side plate slide rail when moving, and the graphite coating between the two can effectively reduce the friction between the two, improve the movement smoothness of the lower tire mold, and facilitate the use of the operator.

[0017] Preferably, two fixing rods distributed along the width direction of the upper die are fixed on the vertical rod, and the two fixing rods are symmetrically distributed. Two circular holes are opened on the fixing rod, and a sliding rod is inserted into the circular hole. A push plate is fixed to one end of the inner side of the sliding rod, and a shoulder is provided at one end of the outer side of the sliding rod. A reset spring is provided on the sliding rod, and the two ends of the reset spring are fixedly connected to the shoulder and the fixing rod respectively.

[0018] By adopting the above technical solution, the two push plates on both sides tend to move toward the middle under the action of the reset tension spring. After the operator puts the workpiece in, the two push plates will move closer to the middle, pressing the two sides of the workpiece to ensure that the workpiece is in the middle position, preventing one end of the workpiece from not resting on the lower tire mold, and further improving the correction effect of the device.

[0019] Preferably, a round rod is rotatably provided above the fixed rod, a rotating hole is opened at the side end of the vertical rod, and the two ends of the round rod are rotatably connected to the rotating holes at corresponding positions, and a pull rope is connected to both sides of the upper tire pressure, and the other end of the pull rope passes around the bottom of the round rod at the corresponding position and is connected to the side of the push plate close to the sliding rod.

[0020] By adopting the above technical solution, when the upper pressure tire moves upward, one end of the pull rope will be pulled upward. At this time, the other end of the pull rope will pull the push plate outward and lengthen the reset spring, which is convenient for the operator to place the workpiece. When the upper pressure tire moves downward, the upper end of the pull rope is relaxed. Under the action of the reset spring, the push plate moves closer to the middle and pushes the workpiece to the middle position, which is convenient for the correction of the workpiece and further convenient for the operator to use.

[0021] Preferably, the bottom of the lower tire mold is provided with a widened edge for increasing the contact area with the mounting plate to prevent the lower tire mold from tilting when subjected to force.

[0022] By adopting the above technical solution, when the lower tire mold moves downward and contacts the mounting plate, the widened edge can improve the stability of the lower tire mold and prevent the lower tire mold from being skewed and deformed.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the workpiece at the placement opening, and then use the press to drive the upper tire and upper die to squeeze downward. The bottom of the upper die is facing the welding position of the workpiece. During the downward pressing process, the workpiece can be squeezed to a vertical state. The workpiece will not slip sideways due to the limitation of the placement opening, making processing more convenient. In addition, the lower tire molds are evenly arranged to provide stable support force, ensuring that the workpiece is evenly stressed when placed, thereby improving the correction effect.

[0024] 2. The opening angle of the placement mouth is 85°-88°. For workpieces with a certain rebound effect, the workpiece can be fully over-corrected so that the workpiece can be in a vertical state after rebound, further improving the correction effect for different workpieces.

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] An embodiment of the present application discloses a T-shaped structural member correction device.

[0028] Example 1 Reference Figure 1-3 The T-shaped structural member correction device includes an upper tire 1, an upper die 2, a lower tire die 3, a mounting plate 4 and a base 5. The bottom of the upper tire 1 is provided with a first concave groove, the upper end of the upper die 2 is fixed to the inner side of the first concave groove by bolts, the cross section of the upper die 2 is T-shaped, the bottom of the upper die 2 is provided with a rounded corner 21, and a plurality of reinforcing ribs 22 for improving strength are fixed on both sides of the upper die 2, and the reinforcing ribs 22 on both sides are symmetrically distributed, and the reinforcing ribs 22 on the same side are evenly spaced. A second concave groove is provided on the upper surface of the seat 5, and the bottom of the mounting plate 4 is fixed to the inner side of the second concave groove by bolts. The lower tire mold 3 is arranged above the mounting plate 4. The lower tire mold 3 is in the shape of a vertical plate, and a placement opening 31 is provided on the lower tire mold 3 for placing T-shaped or L-shaped workpieces. The placement opening 31 is located directly below the upper pressure mold 2 at the corresponding position, and the opening angle of the placement opening 31 is 85°-88°. There are three lower tire molds 3, and the lower tire molds 3 are evenly spaced on the mounting plate 4.

[0029] The upper die 2 is limited by the first concave groove, and the mounting plate 4 is limited by the second concave groove. When the workpiece is corrected, the positions of the upper die 2 and the lower die 3 will not change, and the structure is more stable, thereby improving the accuracy of the correction and improving the correction effect. When the upper die 2 contacts the workpiece, the rounded corners 21 can increase the contact area between the upper die 2 and the workpiece, reduce the impact on the weld, and concentrate the pressure on the lower end of the upper die 2 through the inverted triangle structure, so that the correction part is subjected to appropriate pressure.

[0030] The implementation principle of a T-shaped structural part correction device in an embodiment of the present application is as follows: the upper pressing tire 1 is installed on a press when in use, and a T-shaped workpiece or an L-shaped workpiece is placed at the placement port 31, so that the side of the workpiece that is corrected greater than 90° is facing upward, and then the upper pressing tire 1 and the upper pressing die 2 are driven downward by the press, and the bottom of the upper pressing die 2 is facing the welding part of the workpiece. During the downward pressing process, the workpiece can be squeezed to a vertical state, and the workpiece will not slide sideways, making processing more convenient. The lower tire molds 3 are evenly arranged to provide stable support force, ensure that the workpiece is evenly stressed when placed, and improve the correction effect.

[0031] It should be noted that the opening size of the placement opening 31 of the lower mold 3 can be adjusted according to the size of the workpiece to meet the need for workpiece correction.

[0032] Example 2 Reference Figure 4 and 5 The difference between this embodiment and the first embodiment is that four vertical rods 41 are provided on the upper surface of the mounting plate 4, and the four vertical rods 41 are respectively located at the four corners and symmetrically distributed in the center. Two symmetrically distributed side plate slide rails 42 are fixed on the vertical rod 41, and the side plate slide rails 42 are parallel to the length direction of the upper pressing mold 2. Two sliding holes 32 are respectively provided at both ends of the lower tire mold 3, and the lower tire mold 3 is slidably set on the side plate slide rails 42 through the two sliding holes 32. Two pin holes 43 are provided on the side plate slide rails 42, and the two pin holes 43 are respectively located on both sides of the middle lower tire mold 3. A fixing pin 44 is inserted in the pin hole 43, and an ear plate 33 is fixed to one end of the lower tire mold 3. A rotating hole is provided on the ear plate 33 located in the middle position, and a bidirectional threaded rod 6 is rotatably connected in the rotating hole, and the bidirectional threaded rod 6 cannot be translated along the rotating hole. Threaded holes are provided on the two ear plates 33 on both sides, and are threadedly connected to the bidirectional threaded rod 6 through the threaded holes. A rotating handle 61 is fixed to one end of the bidirectional threaded rod 6.

[0033] By rotating the bidirectional threaded rod 6 by rotating the handle 61, the lower tire mold 3 located in the middle position cannot move to the sides due to the limitation of the fixed pins 44 on both sides, and the two lower tire molds 3 on both sides will move symmetrically towards or away from each other under the drive of the bidirectional threaded rod 6 to adjust the distance between the two lower tire molds 3. The two lower tire molds 3 are always in a symmetrical state. According to the width of the workpiece, the positions of the two lower tire molds 3 on both sides are adjusted to the edge position that can just support the workpiece, so that workpieces of different widths can be processed, which expands the scope of application of the device.

[0034] Two symmetrically distributed fixing rods 7 are fixed on the vertical rod 41, and the fixing rod 7 is parallel to the width direction of the upper pressing mold 2. A round rod 75 is rotatably set above the fixing rod 7. Two symmetrically distributed round holes are provided on the fixing rod 7, and a sliding rod 71 is slidably inserted into the round hole. A push plate 72 is fixed to one end of the inner side of the two sliding rods 71, and a shoulder 73 is provided at one end of the outer side of the sliding rod 71. A reset spring 74 is provided on the sliding rod 71, and the two ends of the reset spring 74 are respectively fixed to the shoulder 73 and the fixing rod 7. A pull rope 76 is connected to both sides of the upper tire pressure 1. The other end of the pull rope 76 passes around the bottom of the round rod 75 at the corresponding position and is connected to the push plate 72.

[0035] When the treadle 72 is in the closed position, the locking yoke 73 is in the closed position, and the locking yoke 73 is in the closed position, so that the treadle 72 is locked and the locking yoke 73 is locked.

[0036] refer to Figure 6 The height of the side plate slide rail 42 is smaller than the height of the slide hole 32, and a spring hole is opened on the inner wall above the slide hole 32, and a thrust spring 34 is arranged in the spring hole, and a top cover 35 is provided at the end of the thrust spring 34 away from the spring hole, and the lower end of the top cover 35 is against the upper surface of the side plate slide rail 42, and the lower surface of the top cover 35 is provided with a graphite coating, which can reduce the friction between the top cover 35 and the upper surface of the side plate slide rail 42, and the bottom of the lower tire mold 3 does not contact the mounting plate 4, so that the lower tire membrane 3 has a certain downward space, and the bottom of the lower tire mold 3 is provided with a widened edge.

[0037] When the upper mold 2 is pressed downward, the lower mold 3 will move downward and compress the thrust spring 34, so that the bottom of the lower mold 3 will be against the mounting plate 4, and the mounting plate 4 will be supported by the mounting plate 4, which can prevent the side plate slide rails 42 from deforming, thereby improving the service life of the side plate slide rails 42 and extending the service life of the device and reducing the maintenance requirements of the device. Moreover, when the lower mold 3 moves downward and contacts the mounting plate 4, the widened edge can improve the stability of the lower mold 3 and prevent the lower mold 3 from skewing and deforming.

[0038] The implementation principle of the second embodiment is as follows: the operator can rotate the rotating handle 61 to drive the bidirectional threaded rod 6 to rotate, which can not only adjust the distance between the two lower tire molds 3, but also ensure that the two lower tire molds 3 are always in a symmetrical state. According to the width of the workpiece, the distance between the two lower tire molds 3 on both sides is adjusted to a distance that is just enough to place the workpiece, so that workpieces of different widths can be processed, which expands the scope of application of the device. Moreover, the lower tire mold 3 is not only slidably set on the side plate slide rail 42, but also can move up and down along the side plate slide rail 42. Under the support of the thrust spring 34, the bottom of the lower tire mold is separated from the mounting plate 4. When moving, no friction is generated between the lower tire mold 3 and the mounting plate 4, and the movement is smoother, which is convenient for work. When the workpiece is corrected, the lower tire mold 3 will move downward and compress the thrust spring 34, so that the bottom of the lower tire mold 3 is against the mounting plate 4. The mounting plate 4 provides support force for the correction workpiece, which can prevent the side plate slide rail 42 from deforming. In addition, when the upper tire 1 moves upward, one end of the pull rope 76 will be pulled upward. At this time, the other end of the pull rope 76 will pull the push plate 72 outward and stretch the reset spring 74. The two push plates 72 are separated to both sides, which is convenient for the operator to place the workpiece. When the upper tire 1 moves downward, the upper end of the pull rope 76 is relaxed. Under the action of the reset spring 74, the push plate 72 moves closer to the middle and pushes the workpiece to the middle position, which is convenient for the correction of the workpiece and further convenient for the operator to use.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
