The device includes a base with a rotating structure rotatably connected to the upper wall cavity of the base. A telescopic rod is fixedly connected to the lower side of the rotating structure, aiming to reduce friction between components caused by uneven force distribution and extend their lifespan. However, this device still has the following drawback: after bending, the metal parts need to be manually removed from the bending device by a worker. This method is not only inefficient but also prone to causing injury to the operator. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metal fitting bending device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal fitting bending device includes a support frame, a support plate fixedly connected to the top of the support frame, an adjustable bending support assembly on the top of the support plate, a fixing frame fixedly connected to the upper surface of the support plate, a dual-axis cylinder fixedly connected to the top of the fixing frame, an extension end of the dual-axis cylinder passing through the fixing frame and fitted with a pressure block, a slide cylinder fixedly connected to one side of the pressure block, a slide rod movably connected inside the slide cylinder, a spring inside the slide cylinder, with both ends of the spring fixed to the slide rod and the slide cylinder respectively, a connecting frame fixedly connected to the bottom end of the slide rod, an inclined surface on the top of the connecting frame, and a collection box on the upper surface of the support frame.

[0007] As a further embodiment of this utility model, the bending support assembly includes multiple through slots, which are formed on the support plate.

[0009] As a further embodiment of this utility model, the upper surface of the support plate is provided with two limiting plates, and protrusions are fixedly connected to both sides of the two limiting plates. Threaded rods are inserted into the interior of the protrusions. The upper surface of the support plate is provided with multiple threaded grooves, and the threaded rods are threadedly connected to the corresponding threaded grooves.

[0010] As a further improvement of this invention, the connecting frame is located between two fixed blocks.

[0011] As a further embodiment of this utility model, two L-shaped plates are fixedly connected at the bottom corner of the support frame, and the L-shaped plates are in contact with the collection box.

[0012] As a further embodiment of this utility model, the top of the collection box is kept at the same level as the upper surface of the support plate, and the lower end of the inclined surface is located on the side of the collection box.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1.

[0015] 2. This utility model allows for adjustment of the height of the slide top extending beyond the support plate by rotating the lead screw, thereby facilitating workers to process metal parts into different bending depths and improving the flexibility of the device.

[0016] 3. The use of threaded grooves and threaded rods facilitates the adjustment of the position of the limiting plate, thereby making it easier for workers to position metal parts of different lengths. Attached Figure Description

Detailed Implementation

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4A metal parts bending device includes a support frame 9, a support plate 7 fixed to the top of the support frame 9 by bolts, and an adjustable bending support assembly on the top of the support plate 7. The bending support assembly includes multiple through slots on the support plate 7, and a slide 1 slidably connected within each slot. A lead screw 20 is rotatably connected to the bottom of the support plate 7 and threadedly connected to the slide 1. When it is necessary to adjust the height of the slide 1 extending beyond the support plate 7, the lead screw 20 is rotated to move the slide 1 upward, facilitating the processing of metal parts by the operator. The support plate 7 has two fixing blocks 2 bolted to its upper surface to achieve different bending depths. A guide rod 19 is bolted to the bottom of the support plate 7 and is slidably connected to the slide 1. The guide rod 19 guides the slide 1, allowing it to move stably. A fixing frame 5 is bolted to the upper surface of the support plate 7, and a dual-axis cylinder 4 is bolted to the top of the fixing frame 5. The extended end of the dual-axis cylinder 4 passes through the fixing frame 5 and is fitted with a pressure block 3. When the metal part to be bent is placed on top of the slide 1, the dual-axis cylinder 4 extends, causing the pressure block 3 to bend. Block 3 moves downward, bending the metal fitting until it contacts the fixed block 2. A sliding cylinder 6 is bolted to one side of the pressure block 3. A sliding rod 17 is slidably connected inside the sliding cylinder 6. A spring 18 is installed inside the sliding cylinder 6, with both ends of the spring 18 fixed to the sliding rod 17 and the sliding cylinder 6 respectively. A connecting frame 16 is bolted to the bottom end of the sliding rod 17. A slope 15 is provided on the top of the connecting frame 16. A collection box 11 is provided on the upper surface of the support frame 9. Simultaneously, the pressure block 3 moves, causing the sliding cylinder 6 to move downward. Since the connecting frame 16 is connected to the support plate 7... When the connecting frame 16 is touched, its position is restricted. Therefore, the slide bar 17 moves downward, causing the slide cylinder 6 to move downward along the slide bar 17. The spring 18 contracts. After bending, the dual-axis cylinder 4 contracts, causing the pressure block 3 to move upward and separate from the accessory. At the same time, the spring 18 rebounds, causing the slide cylinder 6 to move along the slide bar 17 to the top. Then, the dual-axis cylinder 4 continues to contract, causing the slide cylinder 6 to drive the slide bar 17 and the connecting frame 16 to move upward as a whole. This causes the connecting frame 16 to push the bent accessory upward and move it out of the slide frame 1 along the inclined plane 15, and then fall into the collection box 11 for collection.

[0024] In this utility model, it should be noted that the upper surface of the support plate 7 is provided with two limiting plates 8. The limiting plates 8 can restrict the position of the metal parts on the slide 1. Both sides of the two limiting plates 8 are fixed with protrusions 12 by bolts. Threaded rods 13 are inserted into the inside of the protrusions 12. The upper surface of the support plate 7 is provided with multiple threaded grooves 14, and the threaded rods 13 are threadedly connected to the corresponding threaded grooves 14. Through the cooperation of the threaded grooves 14 and the threaded rods 13, it is convenient to adjust the position of the limiting plates 8, thereby facilitating the workers to assist in the positioning of metal parts of different lengths. The connecting frame 16 is located between the two fixing blocks 2. Two L-shaped plates 10 are fixed with bolts at the bottom corner of the support frame 9, and the L-shaped plates 10 are in contact with the collection box 11. The L-shaped plates 10 can restrict the position of the collection box 11 and facilitate the removal of the collection box 11. The top of the collection box 11 is kept at the same level as the upper surface of the support plate 7, and the lower end of the inclined surface 15 is located on the side of the collection box 11.

[0025] Working principle: When bending a metal part is required, first place the metal part to be bent on the top of the slide 1, move the limiting plate 8 to contact both ends of the part, then rotate the threaded rod 13 to insert it into the corresponding threaded groove 14, fixing the position of the limiting plate 8. Then, activate the dual-axis cylinder 4, which extends to move the pressure block 3 downward, bending the metal part until it contacts the fixing block 2. Simultaneously, the pressure block 3 moves, causing the slide cylinder 6 to move downward. Since the connecting frame 16 contacts the support plate 7, At this time, the position of the connecting frame 16 is restricted, so the slide bar 17 moves downward, causing the slide cylinder 6 to move downward along the slide bar 17, and the spring 18 contracts. After bending, the dual-axis cylinder 4 contracts, causing the pressure block 3 to move upward and separate from the accessory. At the same time, the spring 18 rebounds, causing the slide cylinder 6 to move along the slide bar 17 to the top. Then the dual-axis cylinder 4 continues to contract, causing the slide cylinder 6 to drive the slide bar 17 and the connecting frame 16 to move upward as a whole, so that the connecting frame 16 pushes the bent accessory upward and moves it out of the slide frame 1 along the inclined plane 15, and then falls into the collection box 11 for collection.
