Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a bending fixture for metal ornaments. Background Technology

[0002] In the metal ornament processing industry, bending is a common and crucial step, especially for forming decorative metal parts. However, in actual production, due to the diverse shapes of metal ornaments and the high precision requirements of bending, traditional bending methods typically rely on manual operation or simple tools. This method struggles to guarantee consistency in bending angles and positions, especially in mass production, easily leading to dimensional deviations and surface damage. Furthermore, existing bending equipment requires cumbersome and time-consuming adjustments when handling complex-shaped metal ornaments, resulting in low overall efficiency. Simultaneously, with increasing market demands for product quality and appearance, traditional methods are no longer sufficient to meet the demands for efficient and precise processing, necessitating improvements to enhance production efficiency and finished product quality. Utility Model Content

[0003] The purpose of this utility model is to provide a bending fixture for metal ornaments, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a metal ornament bending fixture, which mainly consists of a base, a positioning mechanism set on the base, and an adjustable bending component.

[0005] The base, serving as the fundamental support component of the overall structure, supports and secures other components. A slide rail extends along the length of the base to guide the movement of the bending assembly. The surface of the slide rail is hardened to reduce friction and improve durability. Scale markings are provided on both sides of the slide rail to assist operators in precisely adjusting the position of the bending assembly. A fixing block is also located at one end of the base, connected to the base by bolts, to limit and secure one end of the metal fitting. The inner surface of the fixing block has anti-slip textures to effectively prevent the metal fitting from slipping during processing.

[0006] The positioning mechanism includes a pressure plate, a drive rod, and a locking device, used to fix and position the metal ornament. The pressure plate is located above the base and is connected to the base by a hinge, allowing the pressure plate to rotate within a certain angle range. The lower surface of the pressure plate has an elastic pad made of wear-resistant rubber to protect the surface of the metal ornament from damage. One end of the drive rod is connected to the pressure plate, and the other end passes through the base and engages with the locking device. The locking device includes a nut and a handle. The handle is threaded to the drive rod; rotating the handle drives the drive rod up and down via the threaded transmission, thus raising and lowering the pressure plate. When the pressure plate descends to contact the metal ornament, the elastic pad fits tightly against the metal ornament, securing it in place.

[0007] The bending assembly includes a bending arm, an adjusting mechanism, and a force-applying device, used to perform bending operations on metal ornaments. The bending arm is movably connected to a slide rail via a slider. A ball bearing is embedded inside the slider, and the ball bearing contacts the surface of the slide rail, allowing the bending arm to move smoothly along the slide rail. One end of the bending arm has a bending head, which is arc-shaped and coated with a hard coating to enhance wear resistance and impact resistance. The radius of the arc of the bending head can be changed to accommodate various bending angles. The other end of the bending arm is connected to the adjusting mechanism, which includes a lead screw and a knob. One end of the lead screw is fixedly connected to the bending arm, and the other end passes through the base and engages with the knob. When the knob is rotated, the lead screw pushes the bending arm along the slide rail via threaded transmission, thereby adjusting the relative position between the bending head and the metal ornament.

[0008] The force-applying device includes a lever and a fulcrum, providing power support for the bending operation. One end of the lever is hinged to the bending arm, and the other end has a handle for the operator to grip and apply force. The fulcrum is fixed to the base, located below the center of the lever, and provides a fulcrum for the lever. The top of the fulcrum has a groove with a rolling bearing embedded in it. The rolling bearing contacts the lever, reducing frictional resistance during rotation. When the operator presses down on the lever's handle, the lever rotates around the fulcrum, simultaneously transmitting force to the bending arm, causing the bending head to apply pressure to the metal fitting, completing the bending operation.

[0009] This utility model discloses a metal ornament bending fixture with a compact structure and reasonable design, capable of meeting the needs of efficient and precise processing. The positioning mechanism fixes the metal ornament, avoiding dimensional deviations caused by manual operation in traditional methods; the adjustment mechanism flexibly adjusts the position of the bending head to adapt to metal ornaments of different shapes and specifications; and the force application device provides stable bending power, significantly improving bending efficiency and finished product quality. Furthermore, all components of this utility model adopt a modular design, facilitating disassembly and maintenance, reducing production costs, and making it suitable for large-scale application.

[0013] This utility model discloses a metal ornament bending fixture that achieves precise positioning and efficient bending operation of metal ornaments through its structural design. The following description, in conjunction with the attached... Figure 1 To be continued Figure 2 The specific embodiments of this utility model are described in detail below. The base 1 serves as the basic component of the entire tooling, and is equipped with a slide rail 2 and a fixing block 3. The slide rail 2 extends along the length of the base 1 and its surface is hardened. Scale markings are provided on both sides of the slide rail 2 to assist in adjusting the position of the bending assembly. The fixing block 3 is located at one end of the base 1 and is connected to the base 1 by bolts. The inner surface of the fixing block 3 has anti-slip textures to enhance the limiting effect on the metal trim. The positioning mechanism includes a pressure plate 4, a drive rod 5, and a locking device 6. The pressure plate 4 is hinged to the top of the base 1, and an elastic pad is provided on the lower surface of the pressure plate 4, which directly contacts the surface of the metal trim. One end of the drive rod 5 is connected to the pressure plate 4, and the other end passes through the base 1 and cooperates with the locking device 6. The locking device 6 consists of a nut and a handle. The handle drives the drive rod 5 up and down through threaded transmission, thereby realizing the lifting and lowering action of the pressure plate 4. The bending assembly includes a bending arm 7, an adjusting mechanism 9, and a force-applying device. The bending arm 7 is movably connected to the slide rail 2 via a slider 13. A ball bearing is embedded inside the slider 13, and the ball bearing contacts the surface of the slide rail 2 to reduce friction and ensure smooth movement. One end of the bending arm 7 is equipped with a bending head 8, which is arc-shaped and coated with a hard coating. The radius of the arc of the bending head 8 can be changed to different specifications as needed. The other end of the bending arm 7 is connected to the adjusting mechanism 9, which includes a lead screw and a knob. One end of the lead screw is fixedly connected to the bending arm 7, and the other end passes through the base 1 and engages with the knob. Rotating the knob pushes the bending arm 7 along the slide rail 2 via threaded transmission to adjust the position of the bending head 8. The force-applying device includes a lever 10 and a fulcrum 11. One end of the lever 10 is hinged to the bending arm 7, and the other end is provided with a handle for the operator to hold and apply force. The fulcrum 11 is fixed on the base 1 and located below the middle of the lever 10. A rolling bearing 12 is embedded in the groove at the top of the fulcrum 11. The rolling bearing 12 contacts the lever 10 to reduce frictional resistance during rotation.

[0014] In practical applications, the operator first places the metal ornament to be processed on the base 1, with one end of the metal ornament abutting the inner surface of the fixing block 3. The anti-slip texture on the fixing block 3 effectively prevents the metal ornament from sliding during subsequent processing. The operator then manually flips the pressure plate 4 to cover the metal ornament, and rotates the handle of the locking device 6 to move the drive rod 5 downwards. The drive rod 5, through threaded transmission, lowers the pressure plate 4 until the elastic pad is tightly fitted to the metal ornament, thus fixing the metal ornament. At this point, the operator observes the scale markings on both sides of the slide rail 2 according to the size of the metal ornament and the bending requirements. Rotating the knob of the adjusting mechanism 9, through screw transmission, pushes the bending arm 7 to move along the slide rail 2 until the bending head 8 reaches the predetermined position. During the bending operation, the operator holds the handle of the lever 10 and presses it down. The lever 10 rotates around the rolling bearing 12 at the top of the fulcrum 11 and transmits the force to the bending arm 7. The bending arm 7 drives the bending head 8 to apply pressure to the metal ornament, thereby completing the bending operation. After bending, the operator rotates the handle of the locking device 6 in the opposite direction to raise the pressure plate 4, release the fixation on the metal ornament, and then remove the processed metal ornament.

[0015] This utility model's metal ornament bending fixture achieves efficient processing of metal ornaments through the rational layout and precise coordination of its components. The base 1 provides stable support for the overall structure. The slide rail 2 not only guides the movement of the bending arm 7 but also enhances durability and operational accuracy through surface hardening treatment and graduated markings. The cooperation between the fixing block 3 and the pressure plate 4 ensures the metal ornament remains stable during processing, avoiding processing errors caused by slippage or loosening. The connection between the bending arm 7 and the slide rail 2 via the slider 13 ensures smooth movement, while the lead screw and knob design of the adjusting mechanism 9 allows for more flexible and precise adjustment of the bending head 8. The cooperation between the lever 10 and the fulcrum 11 in the force application device fully utilizes mechanical principles, allowing operators to complete bending operations with relatively small forces, significantly reducing labor intensity. Furthermore, all components of this invention adopt a modular design for easy disassembly and maintenance. For example, the bending head 8 can be quickly replaced to adapt to different bending requirements, and the ball bearings inside the slider 13 and the rolling bearings 12 on the top of the fulcrum seat 11 can be replaced individually to extend the service life of the equipment. As can be seen from the above embodiments, the metal trim bending fixture of this invention not only meets the requirements of efficient and precise processing but also possesses good practicality and economy, making it suitable for large-scale application.

[0016] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0017] In the actual processing, the metal ornament to be bent is first placed on the base 1, with one end pressed tightly against the inner surface of the fixing block 3. The anti-slip texture on the inner side of the fixing block 3 effectively prevents the metal ornament from shifting during subsequent processing by increasing friction. Then, the operator manually flips the pressure plate 4 to cover the metal ornament. At this time, the handle of the locking device 6 is rotated, and the handle drives the drive rod 5 downwards via a threaded transmission. The drive rod 5 pushes the pressure plate 4 down until the elastic pad on the lower surface of the pressure plate 4 is tightly pressed against the metal ornament. This process ensures that the metal ornament remains stable during processing, avoiding processing errors caused by loosening or slippage.

[0018] Next, the operator observes the scale markings on both sides of the slide rail 2 according to the size and bending requirements of the metal ornament, and rotates the knob of the adjustment mechanism 9. The knob drives the bending arm 7 to move along the slide rail 2 via a lead screw until the bending head 8 reaches the predetermined position. A ball bearing is embedded inside the slider 13, and the ball bearing contacts the surface of the slide rail 2, significantly reducing friction and ensuring smooth and precise movement of the bending arm 7. After the position of the bending head 8 is adjusted, the operator holds the handle of the lever 10 and presses it down. The lever 10 rotates around the rolling bearing 12 at the top of the fulcrum 11, and the rolling bearing 12 contacts the lever 10, effectively reducing frictional resistance during rotation. The rotation of the lever 10 transmits force to the bending arm 7, which drives the bending head 8 to apply pressure to the metal ornament, thus completing the bending operation.

[0019] During the bending process, the arc-shaped design of the bending head 8 and its hard coating effectively disperse pressure and reduce damage to the surface of the metal part. Furthermore, the arc radius of the bending head 8 can be changed to accommodate various bending angles. After bending, the operator rotates the handle of the locking device 6 in the opposite direction, causing the pressure plate 4 to rise and release the metal part from its fixation. The finished metal part is then removed, completing the bending operation.

[0020] In the above steps, the precise cooperation between the components achieves efficient and accurate bending results. For example, the hardening treatment of the slide rail 2 not only improves durability but also assists the operator in accurately adjusting the position of the bending head 8 through the scale markings; the cooperation between the fixing block 3 and the pressure plate 4 ensures the stability of the metal parts during processing; the lead screw and knob design of the adjusting mechanism 9 makes the position adjustment of the bending head 8 more flexible and precise; the cooperation between the lever 10 and the fulcrum 11 in the force application device makes full use of mechanical principles, allowing the operator to complete the bending operation with a small amount of force, significantly reducing labor intensity.

[0021] Furthermore, the modular design of this invention further enhances the practicality and economy of the equipment. For example, the bending head 8 can be quickly replaced to adapt to different bending requirements, and the ball bearings inside the slider 13 and the rolling bearings 12 on the top of the fulcrum seat 11 can be replaced individually, extending the service life of the equipment. As can be seen from the above embodiments, the metal trim bending fixture of this invention not only meets the requirements of efficient and precise processing, but also has good practicality and economy, making it suitable for large-scale promotion and application.

[0022] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
