U-shaped wire bending tool

Abstract

This utility model discloses a U-shaped wire bending fixture, including a support plate. A connecting column is rotatably connected inside the support plate. A clamping plate is mounted on the top of the connecting column. A lower clamping block is provided on one side of the clamping plate. A lifting column is fixedly connected to the top of the lower clamping block. An upper clamping block is slidably connected to the surface of the lifting column. In this solution, the locking block is controlled to move in and out of the locking column by a protrusion for limiting the movement. Compared with the original device, by setting a locking column with a locking block, it is ensured that the upper clamping block is prevented from disengaging from the clamping plate without affecting its up-and-down movement, thus not affecting the normal operation of the device and ensuring its practicality. Pulling the pull ring causes the limiting column to slide, locking the mounting block into the mounting groove on the surface of the lower clamping block. Releasing the pull ring causes the spring to push the limiting column into the limiting groove inside the mounting block to complete the installation. This effectively prevents the lower clamping plate from accidentally disengaging from the clamping plate, improving the safety of the device.

Description

Technical Field

[0001] This utility model relates to the field of metal bending equipment technology, and more specifically, to a U-shaped wire bending fixture. Background Technology

[0002] U-shaped screws are a type of specially made U-shaped screw. Their manufacturing process requires bending, which places very high demands on bending machines. The clamping structure is a particularly important component of U-shaped screw bending machines. However, current U-shaped screw bending machines suffer from problems such as non-adjustable clamping structures, overly strict requirements on U-shaped screw specifications, and poor clamping stability.

[0003] To address the aforementioned issues, patent document publication number CN212285652U discloses a clamping structure for a U-shaped wire bending machine, comprising a support auxiliary mechanism and a clamping mechanism. The clamping mechanism penetrates the middle of one end of the support auxiliary mechanism. The support auxiliary mechanism includes a support plate, a reinforcing column, a support column, and an auxiliary clamping mechanism. One side of the reinforcing column is welded to the support plate.

[0004] However, in actual use, it still has some drawbacks. For example, by pushing the pressing tube to pull the lifting column upward, the upper clamping block moves downward, and then the clamping plate mechanism can clamp the U-shaped thread head. The wire rope is then looped around the outside of the anti-slip groove, and finally the U-shaped thread head is firmly clamped and fixed. The clamping operation is simple and the fixation is stable. However, the upper clamping block is only fixed by a pin. During the up and down movement, the pin is easy to disengage from the locking hole, causing it to disengage and need to be re-clamped to continue working, which affects the practicality of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a U-shaped wire bending tool to solve the problem that the pin is easy to detach and jam, which affects the practicality of the device.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a U-shaped wire bending fixture, including a support plate, a connecting column rotatably connected inside the support plate, a clamping plate mounted on the top of the connecting column, a lower clamping block provided on one side of the clamping plate, a lifting column fixedly connected to the top of the lower clamping block, and an upper clamping block slidably connected to the surface of the lifting column; the U-shaped wire bending fixture also includes...

[0007] A card slot is formed inside the clamping disc;

[0008] The surface of the clamping post contacts the sliding groove on the top of the clamping disc, and the surface of the clamping post also contacts the sliding groove inside the upper clamping block.

[0009] A protrusion is slidably connected to the top of the locking post. A sliding post is fixedly connected to the bottom of the protrusion. The surface of the sliding post is slidably connected to the inner wall of the locking post. A stop is fixedly connected to the surface of the sliding post. The surface of the stop is slidably connected to the inner wall of the locking post. A spring is sleeved on the surface of the sliding post. One end of the spring is fixedly connected to the bottom of the stop, and the other end of the spring is fixedly connected to the bottom of the upper inner cavity of the locking post. A slider is fixedly connected to the bottom of the sliding post. A slider is slidably connected to the inclined surface at the bottom of the slider. The surface of the slider is slidably connected to the inner wall of the locking post. A locking block is fixedly connected to one side of the slider. The surface of the locking block is slidably connected to the side wall of the locking post, and the surface of the locking block is in contact with the inside of the locking groove.

[0010] The U-shaped wire bending fixture also includes a limiting component, which is located at the bottom of the lower clamping block.

[0011] The limiting assembly includes a pull ring, a second sliding column, a limiting block, a second spring, a limiting platform, a limiting post, and a mounting block. The pull ring is disposed on the side of the lower clamping block. One end of the second sliding column is fixedly connected to one side of the pull ring, and the other end of the second sliding column is fixedly connected to one side of the limiting block. The second spring is sleeved on the surface of the second sliding column. One end of the second spring is fixedly connected to the inner wall of the lower clamping block, and the other end of the second spring is fixedly connected to the surface of the limiting block. The limiting platform is fixedly connected to the bottom of the lower clamping block. The limiting post is slidably connected inside the limiting platform. One end of the limiting post is fixedly connected to the side of the limiting block away from the second sliding column. The mounting block is fixedly connected to the bottom of the clamping plate, and the limiting groove inside the mounting block contacts the surface of the limiting post.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, pressing the protrusion causes the sliding column one and the stop block to slide down. The stop block squeezes the spring one, which in turn causes the sliding column one to slide down, pushing the sliding block two to slide to the right. This causes the locking block to slide into the locking column, where the locking column is locked into the sliding groove inside the upper clamping block and the locking slot. Releasing the protrusion allows the locking block to slide out of the locking column under the elastic force of the spring one, thus completing the limit. Compared with the original device, by setting the locking column with the locking block, it is ensured that the upper clamping block is prevented from disengaging from the clamping plate without affecting its up and down movement. This does not affect the normal operation of the device and ensures its practicality.

[0014] Pulling the pull ring moves the sliding column two and the limiting block to the right, compressing the spring two and causing the limiting column to slide to the right. At this time, the mounting block is inserted into the mounting groove on the surface of the lower clamping block. Releasing the pull ring, under the elastic force of the spring two, causes the limiting column to be inserted into the limiting groove inside the mounting block, completing the installation. This effectively prevents the lower clamping plate from accidentally detaching from the installation of the clamping plate, improving the safety of the device. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 5 This utility model provides a U-shaped wire bending fixture, including a support plate 1. A connecting column 2 is rotatably connected inside the support plate 1. A clamping plate 3 is installed on the top of the connecting column 2. A lower clamping block 4 is provided on one side of the clamping plate 3. A lifting column 5 is fixedly connected to the top of the lower clamping block 4. An upper clamping block 6 is slidably connected to the surface of the lifting column 5. The U-shaped wire bending fixture also includes...

[0024] The slot 7 is formed inside the clamping plate 3 and is used to restrict subsequent snapping.

[0025] The clamping post 8 has a surface that contacts the sliding groove at the top of the clamping plate 3 and a surface that contacts the sliding groove inside the upper clamping block 6. The clamping post 8 can be installed in the sliding groove inside the upper clamping block 6 and the clamping plate 3. The length of the clamping post 8 is longer than the distance between the two sliding groove openings of the upper clamping block 6 and the clamping plate 3, ensuring that there is enough distance for it to slide up and down.

[0026] A protrusion 9 is slidably connected to the top of the locking post 8. A sliding post 10 is fixedly connected to the bottom of the protrusion 9. The surface of the sliding post 10 is slidably connected to the inner wall of the locking post 8. A stop block 11 is fixedly connected to the surface of the sliding post 10. The surface of the stop block 11 is slidably connected to the inner wall of the locking post 8. A spring 12 is sleeved on the surface of the sliding post 10. One end of the spring 12 is fixedly connected to the bottom of the stop block 11, and the other end of the spring 12 is fixedly connected to the bottom of the upper inner cavity of the locking post 8. A slider 13 is fixedly connected to the bottom of the sliding post 10. A slider 2 14 is slidably connected to the inclined surface at the bottom of the slider 13. The surface of the slider 2 14... The slider 14 is slidably connected to the inner wall of the locking post 8. A locking block 15 is fixedly connected to one side of the slider 14. The surface of the locking block 15 is slidably connected to the side wall of the locking post 8. The surface of the locking block 15 is in contact with the inside of the locking groove 7. The locking block 15 can be controlled to move in and out of the locking post 8 by pressing the protrusion 9. When it enters the locking groove 7, the locking block 15 is released, which can restrict the axial sliding of the locking post 8 out of the locking groove 7. The inclined surface of the slider 13 matches the shape of the sliding groove of the slider 14, which can convert the vertical movement of the slider 13 into the horizontal movement of the slider 14. After the locking post 8 is locked into the locking groove 7, the locking post 8 can move up and down due to the limiting of the locking block 15, but will not slide out of the locking groove 7, thus achieving the limiting effect.

[0027] Among them, such as Figure 2 The U-shaped wire bending fixture also includes a limiting component 16, which is disposed at the bottom of the lower clamping block 4.

[0028] Among them, such as Figures 4 to 5The limiting assembly 16 includes a pull ring 161, a second sliding post 162, a limiting block 163, a second spring 164, a limiting platform 165, a limiting post 166, and a mounting block 167. The pull ring 161 is disposed on the side of the lower clamping block 4. One end of the second sliding post 162 is fixedly connected to one side of the pull ring 161, and the other end of the second sliding post 162 is fixedly connected to one side of the limiting block 163. The second spring 164 is sleeved on the surface of the second sliding post 162. One end of the second spring 164 is fixedly connected to the inner wall of the lower clamping block 4, and the other end of the second spring 164 is fixedly connected to... The limiting block 163 is fixedly connected to the surface, the limiting platform 165 is fixedly connected to the bottom of the lower clamping block 4, the limiting post 166 is slidably connected to the inside of the limiting platform 165, one end of the limiting post 166 is fixedly connected to the side of the limiting block 163 away from the sliding post 162, the mounting block 167 is fixedly connected to the bottom of the clamping plate 3, the limiting groove inside the mounting block 167 is in contact with the surface of the limiting post 166, by pulling the pull ring 161, the limiting post 166 can be moved to slide left and right, and can be locked into the limiting groove inside the mounting block 167 to limit it.

[0029] The working process of this utility model is as follows: Press the protrusion 9 to drive the slide column 10 and the stop block 11 to slide down. The stop block 11 squeezes the spring 12, and the slide column 10 drives the slider 13 to slide down, thereby pushing the slider 14 to slide to the right, causing the locking block 15 to slide into the locking column 8. At this time, the locking column 8 is locked into the upper clamping block 6 and the locking groove 7. Release the protrusion 9, and under the elastic force of the spring 12, the locking block 15 slides out of the locking column 8 to complete the limiting.

[0030] Pulling the pull ring 161 causes the sliding pin 162 and the limiting block 163 to move to the right, compressing the spring 164 and causing the limiting pin 166 to slide to the right. At this time, the mounting block 167 is inserted into the mounting groove on the surface of the lower clamping block 4. Releasing the pull ring 161 causes the limiting pin 166 to be inserted into the limiting groove inside the mounting block 167 under the elastic force of the spring 164, thus completing the installation.
