Description

Technical Field

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

[0002] Bending in hardware processing is a process of bending metal sheets into a specific angle or shape by means of machinery or manual means. It is mainly used in the field of sheet metal processing. Bending uses a mold to apply pressure to the metal sheet, causing it to undergo plastic deformation. First, it goes through the elastic deformation stage, then enters the plastic deformation stage, and finally forms a permanent bend. The mold is usually designed with a V-groove, and the bending axis is ensured to coincide with the center line of the mold through three-point full contact.

[0003] For example, patent number (CN222428964U) discloses a bending device for hardware production, which relates to the field of hardware processing technology. It includes: a workbench, a bending table installed on the top of the workbench, a positioning block provided on one side of the outer end of the bending table, a limiting component provided on the top of the bending table, and a movable component provided on one side of the outer end of the positioning block. This bending device for hardware production can limit hardware of different thicknesses to the top of the workbench through the limiting component, thereby preventing the hardware from warping on one side during the bending process and affecting the bending effect of the hardware. Furthermore, the movable component can ensure that the positioning block can move when the hardware is bent, thereby preventing the hardware from colliding and squeezing with the positioning block during the bending process.

[0004] Currently, the rapid bending device for hardware processing mainly uses the bending die structure for processing. When processing different types of workpieces, the bending die needs to be replaced. Since the bending die involves two parts, the replacement process is relatively complicated, affecting the convenience of the die replacement operation.

[0005] Therefore, to address the above problems, a fast bending device for hardware parts processing that allows for easy replacement of bending dies can be designed. Utility Model Content

[0006] To overcome the problem that changing bending dies in rapid bending devices for hardware processing is cumbersome due to the two-part structure of the bending die, which affects the convenience of die replacement.

[0007] The technical solution of this utility model is as follows: a rapid bending device for hardware processing, including a worktable, a connecting frame fixedly installed on the front side of the upper end of the worktable, a connecting seat provided on the inner side of the connecting frame, a guide support column fixedly installed on the upper side of the connecting seat, a return spring and a movable pressure plate provided on the surface of the guide support column, a pressing seat fixedly installed on the upper end of the movable pressure plate, an upper mold fixedly installed on the lower end of the movable pressure plate, an electric displacement guide rail fixedly installed on the upper end of the connecting seat, a lower mold fixedly installed on the output end of the electric displacement guide rail, a positioning shaft fixedly installed on the front side of the lower end of the upper mold, a positioning hole one opened on the front side of the upper end of the lower mold, and positioning holes two opened on both the left and right sides of the upper end of the connecting seat located on the electric displacement guide rail.

[0008] Preferably, the return spring can be used in conjunction with the guide support column to replace the telescopic cylinder for resetting and pulling the lower mold upward. The entire assembly can be replaced by unscrewing the connecting bolts between the connecting frame and the connecting seat. The electric displacement guide rail can move the lower mold to the loading and unloading area, and the workpiece can be placed on the lower mold. The telescopic cylinder can drive the pressing head to squeeze the pressing seat, and the movable pressure plate can drive the upper mold to press down. This works in conjunction with the lower mold to complete the rapid bending process of the hardware parts. After the telescopic cylinder retracts, the return spring can drive the movable pressure plate and the upper mold to reset.

[0009] Preferably, the connecting frame and the connecting seat are detachably connected, the guide support columns are evenly distributed, the upper end of the guide support column is fixedly installed with a limit block, and the surface of the guide support column is slidably connected with the movable pressure plate.

[0010] Preferably, the return spring and the guide support column are sleeved together, one end of the return spring is fixedly connected to the movable pressure plate, and the other end of the return spring is fixedly connected to the connecting seat.

[0011] Preferably, a support frame is fixedly installed on the rear side of the upper end of the workbench, and a telescopic cylinder is fixedly installed on the upper end of the support frame. The output end of the telescopic cylinder extends into the interior of the support frame to fix the pressing head.

[0012] Preferably, the telescopic cylinder is used to drive the pressing head to move up and down, and the output end of the telescopic cylinder is slidably connected to the support frame.

[0013] Preferably, an electric displacement guide rail is used to drive the lower mold to move back and forth, the pressing seat and the pressing head are in close contact with each other, and the upper mold and the lower mold are adapted to each other.

[0014] Preferably, positioning hole one and positioning hole two are connected to each other, and both positioning hole one and positioning hole two are connected to the positioning shaft pin.

[0015] The beneficial effects of this utility model are:

[0016] 1. This fast bending device for hardware processing uses a return spring and a support structure to reset, assist in supporting, and guide the upper mold, which facilitates the functional connection between the upper mold and the drive structure. Only the pressing function needs to be retained, further eliminating the direct fixation between the upper mold and the drive structure. At the same time, the spring support structure makes the upper mold and the lower mold form a modular whole, which is convenient for mass production. It can also be flexibly disassembled and assembled with the bending device, simplifying the replacement operation process and improving the convenience of mold replacement operation.

[0017] 2. This rapid bending device for hardware processing uses a displacement structure to move and adjust the lower mold, and an auxiliary positioning structure to position the lower mold. This ensures precise alignment of the upper and lower molds during processing, guaranteeing product quality. Furthermore, the displacement allows for the separation of the processing and loading / unloading areas, preventing workers from operating directly under the bending device and avoiding accidental injury. This enhances the safety of the equipment. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of a rapid bending device for hardware parts processing, including a worktable 1. A connecting frame 2 is fixedly installed on the front side of the upper end of the worktable 1. A connecting seat 3 is provided on the inner side of the connecting frame 2. A guide support column 4 is fixedly installed on the side of the upper end of the connecting seat 3. A return spring 5 and a movable pressure plate 6 are provided on the surface of the guide support column 4. A pressing seat 7 is fixedly installed on the upper end of the movable pressure plate 6. An upper mold 8 is fixedly installed on the lower end of the movable pressure plate 6. An electric displacement guide rail 9 is fixedly installed on the upper end of the connecting seat 3. A lower mold 10 is fixedly installed at the output end of the electric displacement guide rail 9. A positioning shaft 11 is fixedly installed on the front side of the lower end of the mold 8. A positioning hole 12 is opened on the front side of the upper end of the lower mold 10. Positioning holes 13 are opened on both the left and right sides of the upper end of the connecting seat 3 located on the electric displacement guide rail 9. The reset spring 5, together with the support structure, resets, provides auxiliary support and guides the upper mold 8, replacing part of the function docking of the drive structure. Only the drive pressing is required, eliminating the direct fixation between the upper mold 8 and the drive structure. Furthermore, the upper mold 8 and the lower mold 10 can be formed into a modular whole, which can be flexibly disassembled and assembled with the bending device, simplifying the replacement operation process.

[0026] Please see Figures 1-5 In this embodiment, the connecting frame 2 and the connecting seat 3 are detachably connected. The guide support columns 4 are evenly spaced, and a limit block is fixedly installed at the upper end of the guide support column 4. The surface of the guide support column 4 is slidably connected to the movable pressure plate 6. The return spring 5 is sleeved with the guide support column 4. One end of the return spring 5 is fixedly connected to the movable pressure plate 6, and the other end of the return spring 5 is fixedly connected to the connecting seat 3. A support frame 14 is fixedly installed on the rear side of the upper end of the workbench 1. A telescopic cylinder 15 is fixedly installed on the upper end of the support frame 14. The output end of the telescopic cylinder 15 extends into the interior of the support frame 14 and a pressing head 16 is fixedly installed. The telescopic cylinder 15 is used to drive the pressing head 16 to move up and down. The output of the telescopic cylinder 15... The end is slidably connected to the support frame 14. The return spring 5 can work with the guide support column 4 to replace the telescopic cylinder 15 to return and pull up the lower mold 10 (the guide support column 4 is used to provide auxiliary support and guide limit for the operation of the movable pressure plate 6, and works with the limit block to prevent the movable pressure plate 6 from detaching). Only the pressing function needs to be retained. The upper mold 8 and the lower mold 10 can be formed into a modular whole (multiple modular molds can be set, and the mold slots can be set according to requirements). The upper mold 8 can be removed from the installation connection with the drive structure. The entire mold can be replaced by unscrewing the connecting bolts of the connecting frame 2 and the connecting seat 3 (the connecting frame 2 is fixed with bolts after engaging the connecting seat 3 to ensure the stability of the connection).

[0027] Please see Figures 1-5In this embodiment, the electric displacement guide rail 9 is used to drive the lower mold 10 to move back and forth. The pressing seat 7 and the pressing head 16 are in contact with each other. The upper mold 8 and the lower mold 10 are adapted to each other. Positioning hole one 12 and positioning hole two 13 are connected to each other. Both positioning hole one 12 and positioning hole two 13 are connected to the positioning shaft 11 by a pin. After restarting the equipment, the electric displacement guide rail 9 can move the lower mold 10 to the loading and unloading area (the electric displacement guide rail 9 can be set as a driving component with similar functions). The workpiece can be placed on the lower mold 10 (the lower mold 10 can be provided with a limiting structure or magnetic suction structure, etc., to fix and limit the workpiece and prevent it from shifting during the movement). The lower mold 10 is then moved to the processing area again by the electric displacement guide rail 9 (the lower mold... The lower end of 10 slides against the connecting seat 3 to support the downward pressure of the upper mold 8 and avoid affecting the electric displacement guide rail 9. The telescopic cylinder 15 can drive the pressing head 16 to squeeze the pressing seat 7 (the telescopic cylinder 15 can be set as a driving component with similar function). The movable pressure plate 6 can drive the upper mold 8 to press down, and cooperate with the lower mold 10 to complete the rapid bending process of the hardware parts. After the telescopic cylinder 15 retracts, the reset spring 5 drives the movable pressure plate 6 and the upper mold 8 to reset. The electric displacement guide rail 9 has precise position control, but after long-term use, it may have a certain deviation due to various factors. The arc surface of the positioning shaft 11 can automatically adjust the possible position error by disassembling and connecting with the positioning hole 12 and the positioning hole 2.

[0028] During operation, the return spring 5, in conjunction with the guide support column 4, replaces the telescopic cylinder 15 in resetting and pulling up the lower mold 10. Only the pressing function needs to be retained, thus facilitating the modularization of the upper mold 8 and the lower mold 10. The installation connection between the upper mold 8 and the drive structure is removed, and the connecting bolts between the connecting frame 2 and the connecting seat 3 are unscrewed, allowing for complete replacement. After replacing the modular mold, the equipment is restarted, and the lower mold 10 is moved to the loading and unloading area via the electric displacement guide rail 9. The workpiece is placed on the lower mold 10, and the lower mold 10 is moved to the processing area again via the electric displacement guide rail 9. The telescopic cylinder 15 drives the pressing head 16 to press the pressing seat 7, causing the movable pressure plate 6 to press down the upper mold 8, thus completing the rapid bending process of the hardware parts with the help of the lower mold 10. After the telescopic cylinder 15 retracts, the return spring 5 drives the movable pressure plate 6 and the upper mold 8 to reset.

[0029] Through the above steps, the reset spring 5, in conjunction with the support structure, resets, provides auxiliary support, and guides the upper mold 8, replacing some of the functions of the drive structure. Only the drive pressing down is required, eliminating the direct fixation between the upper mold 8 and the drive structure. Furthermore, the upper mold 8 and the lower mold 10 can be formed into a modular whole, allowing for flexible assembly and disassembly with the bending device. This simplifies the replacement process and solves the problem that when changing bending dies in a fast bending device for hardware processing, the replacement process is cumbersome due to the involvement of two mold structures, affecting the convenience of mold replacement.
