Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and in particular to a bending structure for hardware processing. Background Technology

[0002] In the field of hardware processing, bending is an extremely important process, and its processing effect directly affects the quality and performance of hardware. When performing bending operations, it is usually necessary to use bending dies and perform bending processing on hardware through stamping.

[0003] Existing bending devices, due to the lack of effective limiting means during the stamping and bending process, make the hardware parts prone to displacement, resulting in poor stability during bending and affecting the bending efficiency and quality of the hardware parts.

[0004] An existing patent (publication number: CN221184286U) discloses a bending device for processing hardware parts. A hydraulic cylinder pushes a support plate downward, which in turn moves a limiting frame and an upper mold downward simultaneously. The limiting frame first contacts the hardware parts placed on the lower mold. As the hydraulic cylinder continues to push, the support spring is compressed, and the hardware parts are effectively limited between the lower mold and the limiting frame. After the upper mold passes through the opening on the limiting frame, it is pressed into the bending groove to perform bending processing on the hardware parts. This prevents the hardware parts from shifting position during bending and improves bending accuracy.

[0005] To address the aforementioned issues, existing patents offer solutions, but they are not convenient for mold replacement. During the hardware processing, various molds of different specifications are required depending on the product requirements. Due to the lack of an effective replacement structure, the connection between the mold and the main body of the equipment is complex, and the replacement operation is cumbersome. This results in a significant amount of time and manpower being spent on mold replacement, which not only affects production efficiency but also increases the company's operating costs and reduces the practicality of the device.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A bending structure for hardware processing includes a housing 1, a fixing component 2 fixedly connected to the top of the housing 1, a fixing bracket 3 fixedly connected to the rear side of the top of the housing 1, a stamping component 4 fixedly connected to the top of the inner wall of the fixing bracket 3, and a hydraulic cylinder 5 provided on the top of the stamping component 4. The stamping component 4 includes a movable plate 401, a T-shaped block 402 movably connected to the bottom inside the movable plate 401, and an upper mold 403 fixedly connected to the bottom of the T-shaped block 402.

[0029] The fixing component 2 includes a U-shaped block 201, a slider 202 is movably connected to the bottom of the inner wall of the U-shaped block 201, and a lower mold 203 is fixedly connected to the top of the slider 202. U-shaped connecting blocks 204 are fixedly connected to both sides of the top of the U-shaped block 201, and bolts 205 are threadedly connected to the top of the U-shaped connecting blocks 204. A pressing plate 206 is rotatably connected to the bottom of the bolts 205, and a rotating ring 207 is fixedly connected to the top of the bolts 205.

[0030] In this embodiment: the cooperation between the slider 202 and the lower mold 203 allows the lower mold 203 to move smoothly inside the U-shaped block 201 under the constraint of the slider 202, enabling the replacement of the lower mold 203. This facilitates the processing of various hardware parts and improves the ease of use of the device. Furthermore, rotating the rotating ring 207 drives the bolt 205 to rotate smoothly, simultaneously causing the pressing plate 206 to move smoothly towards the plate, making the pressing plate 206 contact the surface of the plate. This allows for the fixing of plates of specific specifications, preventing the plate from shaking or shifting due to external forces, reducing the production of defective products, and improving the performance of the fixing component 2. The ease of use is achieved by moving the handle 408, which in turn moves the moving rod 407 smoothly, simultaneously moving the moving block 404 and the positioning block 405 within the moving plate 401. This releases the upper mold 403 from its fixation, allowing it to move smoothly within the moving plate 401 under the constraint of the T-block 402, thus enabling the replacement of the old and new upper molds 403. Subsequently, the force applied to the handle 408 is released, allowing the spring 406 to push the moving block 404 back to its original position and lock the T-block 402, thereby completing the replacement of the upper mold 403. This facilitates the processing of various hardware parts and improves the ease of use of the stamping assembly 4.

[0031] Specifically, such as Figure 4 As shown, a moving block 404 is movably connected to the front side inside the moving plate 401, a positioning block 405 is fixedly connected to the rear side of the moving block 404, and several springs 406 are fixedly connected to the side of the moving block 404 away from the positioning block 405. A moving rod 407 is fixedly connected to the side of the moving block 404 away from the positioning block 405, and the other end of the moving rod 407 extends to the front side of the moving plate 401 and is fixedly connected to a handle 408.

[0032] Specifically, such as Figure 4 As shown, a connecting groove 6 is provided on the left side of the movable plate 401 to cooperate with the T-shaped block 402, and the surface of the T-shaped block 402 is in contact with the inner wall of the connecting groove 6.

[0033] Specifically, such as Figure 4 As shown, the front side of the movable plate 401 is provided with a movable groove 7 for use with the movable block 404, and the side of the spring 406 away from the movable block 404 is fixedly connected to the front side of the inner wall of the movable groove 7. The rear side of the inner wall of the movable groove 7 is provided with a movable hole 8 for use with the positioning block 405, and the movable hole 8 communicates with the connecting groove 6. The front side of the movable plate 401 is provided with a connecting hole 9 for use with the movable rod 407, and the connecting hole 9 communicates with the movable groove 7.

[0034] In this embodiment: the T-block 402 and the connecting groove 6 work together to allow the T-block 402 to move smoothly under the constraint of the connecting groove 6, simultaneously driving the upper mold 403 to move smoothly to the appropriate position, which facilitates the installation of the upper mold 403. Then, through the connection hole 9 and the moving groove 7, the handle 408 drives the moving rod 407 to move smoothly under the constraint of the connection hole 9, simultaneously driving the moving block 404 to move under the moving groove 7. At the same time, through the connection hole 8 and the connecting groove 6, the positioning block 405 can be moved smoothly, which can release the fixed state of the upper mold 403. After the upper mold 403 replacement operation is completed, under the action of the spring 406, the moving block 404 can be pushed to return smoothly to its original position, thereby allowing the upper mold 403 to be replaced, which facilitates the processing of various hardware parts and improves the ease of use of the stamping assembly 4.

[0035] Specifically, such as Figure 5 As shown, a rubber pad 10 is fixedly connected to the bottom of the pressing plate 206, and sliding rods 11 are fixedly connected to both sides of the top of the pressing plate 206.

[0036] Specifically, such as Figure 5 As shown, the front side of the U-shaped block 201 is provided with a groove 12 for use with the slider 202, and a positioning plate 13 is fixedly connected inside the groove 12. The slider 202 is movably connected to the surface of the positioning plate 13, and a buckle block 14 is rotatably connected to the front side of the positioning plate 13.

[0037] In this embodiment: the slider 202 and the slide groove 12 work together to allow the slider 202 to move smoothly inside the slide groove 12 under the restriction of the positioning plate 13, which can drive the lower mold 203 to move smoothly, realizing the replacement of the lower mold 203. At the same time, under the action of the buckle block 14, the slider 202 can be locked, making the connection between the lower mold and the U-shaped block 201 more secure, preventing it from shaking or shifting due to external force, ensuring the bending effect of the hardware, and improving the convenience of using the fixing component 2. Then, under the action of the slide rod 11, the movement of the pressing plate 206 can be restricted, which can smoothly fix the plate. At the same time, under the action of the rubber pad 10, the friction between the plate and the plate can be increased, making the fixation more secure, and a part of the impact force can be buffered to prevent the plate from being damaged due to fixation, thus improving the stability of the device.

[0038] Specifically, such as Figure 1 As shown, a control console 15 is fixedly connected to the front right side of the chassis 1, and the control console 15 is electrically connected to the hydraulic cylinder 5.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, spotlights 16 are fixedly connected to the four corners of the top of the inner wall of the fixed bracket 3, and the spotlights 16 are electrically connected to the control panel 15.

[0040] In this embodiment: the control console 15 can precisely adjust the hydraulic cylinder 5 according to the actual situation, so that it drives the upper mold 403 to move smoothly, realizing the bending operation of the sheet metal. At the same time, under the effect of the spotlight 16, sufficient light can be provided to the bending area, so that the operator can clearly observe the bending operation of the sheet metal, ensuring the processing effect of the hardware, reducing processing errors caused by poor visibility, and improving the ease of use of the device.

[0041] Working Principle: When bending hardware parts, the operator first rotates the latch block 14 to release the lock on the slider 202, allowing the lower die 203 to move smoothly within the U-shaped block 201 under the constraint of the positioning plate 13, thus replacing the lower die 203. Then, the latch block 14 is rotated to lock the slider 202, ensuring a tight connection between the lower die 203 and the U-shaped block 201, preventing wobbling or displacement due to external forces and guaranteeing the bending effect of the hardware parts. After replacing the lower die 203, the sheet metal is placed on top of it. By rotating the rotating ring 207, the bolt 205 is rotated smoothly, simultaneously moving the pressing plate 206 towards the sheet metal, making contact between the pressing plate 206 and the surface of the sheet metal, thus fixing the sheet metal of a specific specification. After fixing the sheet metal, if it is necessary to replace the upper die 403, the operator pulls the handle 40. 8. The moving rod 407 moves smoothly, simultaneously moving the moving block 404 and the positioning block 405 inside the moving plate 401. This releases the upper mold 403 from its fixation, allowing it to move smoothly within the moving plate 401 under the constraint of the T-block 402, thus replacing the old upper mold 403 with the new one. Then, the handle 408 is released, allowing the spring 406 to push the moving block 404 back to its original position, causing the positioning block 405 to re-lock the T-block 402, completing the replacement of the upper mold 403. After the replacement of the upper mold 403 is completed, the operator can use the controller to turn on the spotlight 16 to provide sufficient illumination for the bending area, allowing the operator to clearly observe the processing. The operator can also operate the hydraulic cylinder 5 to move the moving plate 401 and the upper mold 403 to the lower mold 203, thus realizing the bending operation of the hardware parts.

[0042] The above are merely preferred embodiments of the present utility model and are 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.
