Description

Technical Field

[0001] This utility model relates to the technical field of hook bending equipment, specifically a hook bending device for explosion-proof water bags. Background Technology

[0002] Currently, the hooks used with explosion-proof water bag racks in mines are small in size and lack dedicated hook bending equipment. The self-made hook bending molds used previously relied entirely on manual operation, resulting in low work efficiency. Furthermore, the finished hooks were affected by human factors, with inconsistent opening sizes, making the water bags prone to falling off, tilting, or failing to fully unfold, thus causing the explosion-proof barrier to fail. Utility Model Content

[0003] The purpose of this utility model is to provide a bending device for the hook of an explosion-proof water bag, so as to solve the problems that the hooks of the explosion-proof water bag frame are small in size and lack dedicated bending equipment. Previously used self-made bending molds relied entirely on manual operation, resulting in low work efficiency. Moreover, the finished hooks were affected by human factors, and their opening size was inconsistent, which made the water bags easy to fall off, tilt or fail to fully unfold, resulting in the failure of the explosion-proof barrier.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bending device for a water-resistant bag hook, comprising a placement plate, an operating frame, a positioning seat, and a support device. Support columns are connected to the four corners of the bottom of the placement plate. An operating frame is fixedly connected to any one side of the top of the placement plate. The operating frame is arc-shaped, with a through hole in its center for a rotating shaft to pass through. The rotating shaft passes through the operating frame, with an operating handle connected to the outer circumference of one end and an installation groove on the other end. The positioning seat is detachably mounted on the rotating shaft via a keyway. The positioning seat has a vertically positioned positioning hole, and a corresponding positioning hole is provided on the rotating shaft. A corresponding through hole is provided at the position of the positioning hole. A support device is provided below the through hole on the rotating shaft, including a support plate and a slide. The support plate is connected to the placement plate and has a sliding groove. The end of the sliding groove is semi-circular and coaxial with the positioning hole. The semi-circular end abuts against the outer circumference of the wire rod. A slide is provided on the sliding groove and slides in cooperation with the support plate. The top of the slide is semi-circular and abuts against the outer circumference of the wire rod. A limit rod is connected to the operating frame. The position of the limit rod is staggered with the position of the through hole on the rotating shaft, and the outer circumference of the limit rod abuts against the wire rod.

[0005] Preferably, it also includes a fixing plate connected to the operating frame. The fixing plate has an internal threaded through hole, and a fixing rod is connected in the internal threaded through hole. The fixing rod is provided with an external threaded section, which cooperates with the internal thread. The threaded end of the fixing rod abuts against the positioning seat.

[0006] Preferably, it also includes a base connected to a support plate, the base having an internal threaded through hole, a transversely arranged extension on the slide, a connecting hole on the extension, a threaded rod inside the connecting hole, the threaded rod passing through the extension and its top end screwed onto the base.

[0007] Preferably, a dial is connected to one end of the operating handle on the operating frame.

[0008] Preferably, the rotating shaft is connected to the contact end with the operating frame by a bearing.

[0009] Compared with the prior art, the beneficial effects of this utility model are: By placing the wire rod inside the positioning seat and passing it through the through hole on the rotating shaft, it is ensured that the top of the wire rod is not higher than the upper surface of the positioning seat, and the bottom end is supported and positioned by the semi-circular structure at the end of the slide table and the slide groove. Turning the handle drives the rotating shaft to rotate, causing the positioning seat and the wire rod to bend. During this process, the bending angle can be clearly observed through the scale, thereby ensuring the uniformity of the opening size of the finished hook. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Example 1: Please refer to Figure 1-5This utility model provides an embodiment of a water-resistant bag hook bending device, comprising a placement plate 1, an operating frame 3, a positioning seat 7, and a support device 9. Support columns 2 are connected to the four corners of the bottom of the placement plate 1, forming a base platform that supports all operating components and provides stable support to ensure no shaking during bending. A rectangular support frame with dimensions of 600*150*300 mm can be welded using channel steel, angle steel, etc. The operating frame 3 is fixedly connected to any one side of the top of the placement plate 1. The operating frame 3 is arc-shaped, with a through hole in its center for the rotating shaft 5 to pass through. The arc-shaped structure disperses stress and prevents bending. The rotating shaft 5 deforms over time, and the central through hole ensures the centering of the rotating shaft 5. The rotating shaft 5 passes through the operating frame 3, and a bearing is connected to the contact end of the rotating shaft 5 and the operating frame 3. An operating handle 6 is connected to the outer circumference of one end, which is an extended lever arm used to drive the rotating shaft 5 to rotate, so as to apply the minimum pressure to the rotating shaft 5 and generate the maximum bending force, thereby bending the wire rod to the required angle to form an explosion-proof hook. An installation groove is opened on the other end, and the positioning seat 7 is detachably installed in the installation groove on the rotating shaft 5 through a keyway connection. The rotating shaft 5 drives the positioning seat 7 to rotate to achieve bending, and the keyway connection allows for quick replacement. A vertically positioned positioning hole is provided on the top of the wire rod to fix the top of the wire rod. When the wire rod is placed, its top end does not exceed the top end of the positioning seat 7, thus determining the bending start point. The vertical positioning hole constrains the radial displacement of the wire rod. A corresponding through hole is provided on the rotating shaft 5 at the position of the positioning hole. The through hole and the positioning hole are coaxial to ensure that the wire rod passes through the positioning hole in a straight line. A support device 9 is provided below the through hole on the rotating shaft 5, including a support plate 901 and a slide 903. The support plate 901 is connected to the placement plate 1 and is used to support the bottom end of the wire rod, providing bottom end positioning of the wire rod. It cooperates with the rotating shaft 5 to bend the wire rod into an explosion-proof shape. The small hook has a groove on it, which provides the movement range of the slide table 903. After bending, the slide table 903 can be disassembled, and the explosion-proof hook can be removed. The end of the groove is semi-circular, coaxial with the positioning hole, and abuts against the outer circumference of the wire rod. The slide table 903 is mounted on the groove and slides against the support plate 901. The top of the slide table 903 is semi-circular, abutting against the outer circumference of the wire rod, providing double-point support for the bottom of the wire rod and resisting bending reaction force. The semi-circular end of the groove and the semi-circular end of the slide table 903 clamp and fix the wire rod. Please refer to [link / reference]. Figure 4 The circle between the top semicircle of the slide table 903 and the end semicircle of the slide groove corresponds to the bottom diameter of the wire rod. The operating frame 3 is connected to a limit rod 10. The limit rod 10 and the through hole on the rotating shaft 5 are arranged alternately. The outer circumference of the limit rod 10 abuts against the wire rod, constraining the wire rod to cooperate with the rotating shaft 5 and bending the wire rod into an explosion-proof hook.

[0021] It also includes a fixing plate 8, which is connected to the operating frame 3. The fixing plate 8 has an internal threaded through hole, and a fixing rod 801 is connected in the internal threaded through hole. The fixing rod 801 is provided with an external threaded section, which is used in conjunction with the internal thread. The threaded end of the fixing rod 801 abuts against the positioning seat 7. After installation, the fixing rod 801 is screwed onto the fixing plate 8 to lock the positioning seat 7 to prevent rotational displacement. The threaded tightening structure provides a stable locking force.

[0022] It also includes a base 902 connected to the support plate 901. The base 902 has an internal threaded through hole. The slide 903 has a transversely arranged extension. The extension provides the installation position for the slide 903 and the base 902 and is connected to the base 902 as a whole by a threaded rod. The extension has a connecting hole with a threaded rod inside. The threaded rod passes through the extension and its top end is screwed onto the base 902 to fix the position of the slide 903 and prevent the wire rod from shaking when bending.

[0023] A dial 4 is connected to one end of the operating handle 6 on the operating frame 3 to display the rotation angle of the rotating shaft 5, visually control the bending arc, and ensure that the bending degree of the bar is consistent.

[0024] In use, first place the device on the ground, then install the positioning seat 7 on the rotating shaft 5, screw the fixing rod 801 onto the fixing plate 8, and lock the positioning seat 7 to prevent rotational displacement. Then, pass the wire rod through the positioning hole and through hole, with the bottom end abutting against the semi-circular part on the slide groove. Then, install the slide table 903, with the semi-circular top of the slide table 903 abutting against the outer circumference of the wire rod, and simultaneously connect and fix it to the base 902 through the threaded rod. Then, drive the rotating shaft 5 to rotate by operating the handle 6 to bend the wire rod. Then, disassemble the slide table 903 and take out the bent wire rod.
