[0005] The existing tooling fixtures for bending steel pipes can fix and limit the workpiece, but they are not convenient for the bending blocks to be designed and replaced according to different bending requirements, resulting in poor versatility of the tooling fixtures. Summary of the Invention

[0021] Compared with the prior art, the bending fixture provided by this utility model has the following advantages:
[0022] 1. In this bending fixture, the positioning bolt can accurately install the fixed seat on the fixture plate, ensuring the accuracy of the overall position of the fixed components.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Example 1:
[0036] like Figure 1-5 As shown, the bending fixture provided by this utility model includes a fixture plate 1, a base plate 2 fixedly installed on the outer surface of the fixture plate 1, a placement frame 3 fixedly installed on the other end of the base plate 2 away from the fixture plate 1, a rotating shaft 4 fixedly installed on the inner surface of the placement frame 3, and a roller 5 rotatably installed on the outer surface of the rotating shaft 4. A fixing component 6, a label plate 7 and a moving component 8 are fixedly installed on the end of the fixture plate 1 near the base plate 2. The fixing component 6 and the moving component 8 are located on the same horizontal line.
[0037] See further Figure 6 and Figure 7 In this example, the fixing component 6 includes a fixing seat 601. A positioning bolt 602 is threadedly connected to the outer surface of the fixing seat 601, penetrating the fixing seat 601 and extending into the fixture plate 1. A sliding groove 603 is formed on the outer surface of the fixing seat 601. A baffle 604 is fixedly installed at the other end of the fixing seat 601 away from the fixture plate 1. A plurality of equally spaced fixing holes 605 are formed on the outer surface of the fixing seat 601. A slider 606 is slidably connected to the inner surface of the sliding groove 603. A moving plate 607 is fixedly installed at the other end of the slider 606 away from the sliding groove 603. A slot 608 and a fixing hole 609 are formed on the outer surface of the moving plate 607. The fixing holes 605 and 609 are compatible. A fixing bolt 610 is provided on the outer surface of the fixing hole 609. The outer surface of the fixing bolt 610 penetrates the fixing hole 605 and extends into the fixing hole 609.
[0038] With this configuration, the fixing seat 601 can be precisely installed on the fixture plate 1 using the positioning bolt 602, ensuring the accuracy of the overall position of the fixing component 6. The cooperation between the slide groove 603 and the slider 606 allows the moving plate 607 to be flexibly adjusted to adapt to workpieces of different sizes, improving the versatility of the fixture. The design of multiple fixing holes 605, fixing holes 609, and fixing bolts 610 can firmly fix the moving plate 607 after the position is adjusted, ensuring that the workpiece will not be displaced during bending and guaranteeing processing accuracy.
[0039] Furthermore, in this example, a card block 611 is inserted and installed on the outer surface of the card slot 608, a fixing block 612 is fixedly installed on the outer surface of the card block 611, an extension block 614 is fixedly installed on the outer surface of the fixing block 612, and a positioning bolt 615 is provided on the outer surface of the extension block 614, which penetrates the extension block 614 and extends into the interior of the movable plate 607.
[0040] With this configuration, the insertion and engagement of the slot 608 and the block 611 in this example facilitates the installation and positioning of the fixing block 612. The positioning bolt 615 further enhances the stability of the fixing block 612, preventing it from shaking or shifting during bending, ensuring accuracy when engaging with the moving component 8, and improving bending quality.
[0041] Furthermore, in this example, a bending groove 613 is provided on the outer surface of the fixed block 612, and the bending groove 613 is adapted to the moving component 8.
[0042] With this setup, after the fixing block 612 is installed, the workpiece to be bent can be placed in a suitable position so that its bending point corresponds to the bending groove 613. The design of the bending groove 613 provides precise positioning and guidance for the bending of the workpiece, enabling the moving component 8 to act more accurately on the bending part of the workpiece during the bending operation, ensuring the consistency of the bending angle and shape, and improving the quality stability of the product.
[0043] Example 2:
[0044] This example provides an optimized solution based on the solution in Example 1.
[0045] Combination Figures 1 to 5 and appendix Figure 8 As shown in the figure, this example provides a specific configuration scheme for the mobile component 8.
[0046] Based on the illustration, the movable component 8 specifically includes a fixed base 801, a positioning bolt 802 on the outer surface of the fixed base 801, a sliding groove 803 on the outer surface of the fixed base 801, a limiting plate 804 fixedly installed on the outer surface of the fixed base 801, a cylinder 805 fixedly installed on the outer surface of the limiting plate 804, a movable plate 806 fixedly installed on the output shaft of the cylinder 805, and the movable plate 806 and the sliding groove 803 are slidably connected.
[0047] With this configuration, the positioning bolt 3 802 ensures the accuracy of the installation position of the fixed base 2 801, laying the foundation for the stable operation of the entire moving assembly 8. The sliding connection between the slide groove 2 803 and the moving plate 2 806 restricts the movement direction of the moving plate 2 806, ensuring that it can only move in a straight line along a predetermined direction, thus improving the accuracy and reliability of the bending action.
[0048] Furthermore, in this example, a bending column 807 is fixedly installed at the other end of the movable plate 806 away from the cylinder 805, and a bending block 808 is fixedly installed on the outer surface of the bending column 807, with the bending block 808 corresponding to the bending groove 613.
[0049] With this configuration, the bending column 807 and bending block 808 in this example can be tightly fitted with the bending groove 613 on the fixed block 612, effectively transmitting the power of the cylinder 805 to the workpiece and achieving precise bending action. The shape and size of the bending block 808 can be designed and replaced according to different bending requirements, further improving the versatility and adaptability of the tooling fixture.
[0050] Combination Figure 5 As shown, in this example, the rollers 5 and the rotating shaft 4 are adapted to each other. There are multiple rollers 5 and rotating shaft 4, and the multiple rollers 5 and rotating shaft 4 are distributed at equal intervals.
[0051] With this configuration, when placing or moving the workpiece, the workpiece contacts the roller 5, and the roller 5 can rotate freely around the rotating shaft 4. The fit and equidistant distribution of the roller 5 and the rotating shaft 4 make the workpiece move more smoothly within the placement frame 3, reducing friction and preventing scratches on the workpiece surface. It also facilitates the rapid positioning and adjustment of the workpiece, thus improving processing efficiency.
[0052] The following is a detailed explanation of the usage process of the bending fixture formed based on the above example scheme.
[0053] like Figures 1 to 8 As shown, when this bending fixture is in use, the positioning bolt 602 can accurately install the fixed seat 601 on the fixture plate 1, ensuring the accuracy of the overall position of the fixed component 6. The cooperation between the slide groove 603 and the slider 606 allows the moving plate 607 to be flexibly adjusted to adapt to workpieces of different sizes, thus improving the versatility of the fixture.
[0054] The design of multiple fixing holes 605 and 609, as well as fixing bolts 610, allows for the secure fixing of the moving plate 607 after the position is adjusted, ensuring that the workpiece will not shift during bending and guaranteeing machining accuracy.
[0055] Based on this, the insertion and engagement of the slot 608 and the block 611 facilitates the installation and positioning of the fixing block 612. The positioning bolt 615 further enhances the stability of the fixing block 612, preventing it from shaking or shifting during bending, ensuring accuracy when engaging with the moving component 8, and improving bending quality.
[0056] After the fixing block 612 is installed, the workpiece to be bent is placed in a suitable position so that its bending part corresponds to the bending groove 613. The design of the bending groove 613 provides precise positioning and guidance for the bending of the workpiece, so that the moving component 8 can act more accurately on the bending part of the workpiece during the bending operation, ensuring the consistency of the bending angle and shape, and improving the quality stability of the product.
[0057] The positioning bolt 802 ensures the accuracy of the installation position of the fixed base 801, laying the foundation for the stable operation of the entire moving assembly 8. The sliding connection between the slide groove 803 and the moving plate 806 restricts the movement direction of the moving plate 806, allowing it to move only in a straight line along a predetermined direction, thus improving the accuracy and reliability of the bending action. The design of the bending column 807 and the bending block 808 allows them to fit tightly with the bending groove 613 on the fixed block 612, effectively transmitting the power of the cylinder 805 to the workpiece and achieving precise bending action. The shape and size of the bending block 808 can be designed and replaced according to different bending requirements, further improving the versatility and adaptability of the tooling fixture.
[0058] When placing or moving a workpiece, the workpiece contacts the roller 5, which can rotate freely around the shaft 4. The fit and equidistant distribution of the roller 5 and the shaft 4 make the workpiece move more smoothly within the placement frame 3, reducing friction and preventing scratches on the workpiece surface. It also facilitates quick positioning and adjustment of the workpiece, improving processing efficiency.
[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
