Technical Field
[0001] This utility model relates to the field of cold bending machine blade replacement technology, and in particular to a cold bending machine blade replacement structure. Background Technology
[0002] A cold bending machine is a large-scale piece of equipment used for bending sheet metal such as aluminum and stainless steel sheets, and is widely used in industrial production. When bending sheet metal, a cold bending machine relies on a deep-throat gooseneck bender to achieve the desired bending effect. Different types of benders are required for different types and thicknesses of sheet metal.
[0003] Currently, cold bending machines require the installation of large bending blades of various types at the bottom of the workpiece during operation. Since these blades can be several meters long, multiple fixing units are needed for their installation and replacement. The process involves disassembling and assembling bolts on multiple fixing units, and the heavy weight of the blades necessitates multi-person collaboration, making the operation cumbersome, time-consuming, and impacting the operator's bending efficiency. Therefore, a blade replacement structure for cold bending machines is needed to meet these requirements. Utility Model Content
[0004] The purpose of this utility model is to provide a blade replacement structure for a cold bending machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A blade replacement structure for a cold bending machine includes a bending member, on which a large curved blade is detachably mounted. A snap-fit plate is fixedly mounted on the bottom of the bending member, and a snap-fit groove is formed on the snap-fit plate. A snap-fit plate is snapped into the groove and fixedly mounted on the large curved blade. A retaining plate is movably disposed on one side of the snap-fit plate. A retaining plate adjustment assembly is provided on the bending member and the retaining plate. A hydraulic lifting arm is fixedly mounted on the bending member, and a lifting plate is fixedly mounted on the output end of the hydraulic lifting arm. A horizontal adjustment plate is slidably disposed on the bottom of the lifting plate, and a washing disc is fixedly mounted on the bottom of the horizontal adjustment plate. The washing disc is adsorbed onto the large curved blade. A horizontal adjustment plate adjustment assembly is provided on the lifting plate and the horizontal adjustment plate.
[0007] Preferably, the fixing plate adjustment assembly includes an adjusting screw rotatably disposed on one side of the fixing plate adjustment assembly, a screw sleeve is sleeved on the adjusting screw, and the screw sleeve is fixedly installed on one side of the fixing plate.
[0008] Preferably, a guide frame is fixedly installed on one side of the bending member, a guide sleeve is fixedly installed on the fixing plate, the guide sleeve is slidably sleeved on the guide frame, and a limit block is fixedly installed at the bottom end of the guide frame.
[0009] Preferably, an upper support plate and a lower support block are fixedly installed on the other side of the bending member. An adjusting motor is fixedly installed on the upper support plate, and a rotating shaft is fixedly installed at the output end of the adjusting motor. An adjusting shaft is rotatably installed on the lower support block. A pulley mechanism is provided on the rotating shaft and the adjusting shaft, and the adjusting screw is fixedly installed on the pulley mechanism.
[0010] Preferably, the leveling plate adjustment assembly includes a T-shaped groove formed at the bottom of the lifting plate, a T-shaped slider fixedly installed on the top of the leveling plate, the T-shaped slider being slidably installed in the T-shaped groove, and a leveling plate drive mechanism being provided on the lifting plate and the leveling plate.

[0013] The beneficial effects of this utility model are:
[0014] In this invention, the design incorporates a slot, a clamping plate, a washing disc, a hydraulic lifting arm, and a retaining plate. Extending the hydraulic lifting arm lowers the lifting plate, which then adheres to the top of the large curved blade. Retracting the hydraulic lifting arm lifts the large curved blade upwards via the washing disc. A horizontal adjusting plate slides forward at the bottom of the lifting plate, engaging the clamping plate in the slot. The retaining plate moves downwards and rests against the front of the clamping plate, thus installing the large curved blade at the bottom of the bending component. The clamping plate then separates from the slot, and the hydraulic lifting arm places the large curved blade on the bending table.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example:
[0025] like Figure 1-6As shown, this embodiment provides a blade replacement structure for a cold bending machine, including a bending member 1, a large curved blade 2 detachably mounted on the bending member 1, a snap-fit plate 3 fixedly mounted on the bottom of the bending member 1, a snap-fit groove 4 opened on the snap-fit plate 3, a snap-fit plate 5 snapped into the groove 4, the snap-fit plate 5 fixedly mounted on the large curved blade 2, a retaining plate 6 movably arranged on one side of the snap-fit plate 5, a retaining plate adjustment assembly 7 provided on the bending member 1 and the retaining plate 6, a hydraulic lifting arm 8 fixedly mounted on the bending member 1, a lifting plate 9 fixedly mounted at the output end of the hydraulic lifting arm 8, a horizontal adjustment plate 10 slidably arranged at the bottom of the lifting plate 9, a washing plate 11 fixedly mounted at the bottom of the horizontal adjustment plate 10, the washing plate 11 adsorbed onto the large curved blade 2, and a horizontal adjustment plate adjustment assembly provided on the lifting plate 9 and the horizontal adjustment plate 10.
[0026] Place the large curved blade 2 to be replaced on the bending table and straighten it. Extending the hydraulic lifting arm 8 will lower the lifting plate 9, which in turn lowers the horizontal adjusting plate 10, which in turn lowers the washing plate 11. The washing plate 11 will then adhere to the top plane of the large curved blade 2. Retracting the hydraulic lifting arm 8 will lift the large curved blade 2 upwards via the washing plate 11, aligning the clamping plate 5 with the clamping slot 4. The horizontal adjusting plate adjustment assembly will drive the horizontal adjusting plate 10 to slide forward at the bottom of the lifting plate 9, thus engaging the clamping plate 5 within the clamping slot 4, achieving initial positioning of the large curved blade 2. It should be noted that in the initial state, the retaining plate 6 is located above the clamping plate 5 and does not affect the rising and moving of the large curved blade 2. Then, by driving the retaining plate adjustment assembly 7 downwards and pressing it against the front of the clamping plate 5, the clamping plate 5 can be secured, allowing the large curved blade 2 to be installed at the bottom of the bending component 1. When it is necessary to disassemble the large curved blade 2, the fixing plate 6 is adjusted to rise and misalign with the clamping plate 5 by adjusting the fixing plate adjusting assembly 7. Then, the clamping plate 5 is separated from the clamping slot 4 by adjusting the horizontal adjusting assembly. The large curved blade 2 is then placed on the bending table by the hydraulic lifting arm 8. Finally, the washing plate 11 is removed from the large curved blade 2 to complete the disassembly of the large curved blade 2. It is time-saving, labor-saving, and relatively convenient to operate.
[0027] In this utility model, specifically, the fixing plate adjustment assembly 7 includes an adjustment screw 71 rotatably disposed on one side of the fixing plate adjustment assembly 7, a screw sleeve 72 sleeved on the adjustment screw 71, and the screw sleeve 72 fixedly installed on one side of the fixing plate 6.
[0028] To adjust the position of the retaining plate 6, the rotation of the adjusting screw 71 will cause the screw sleeve 72 to move up and down, thereby adjusting the position of the retaining plate 6 so that the retaining plate 6 abuts against one side of the clamping plate 5, or is misaligned and separated from the clamping plate 5.
[0029] In this utility model, a guide frame 74 is fixedly installed on one side of the bending member 1, a guide sleeve 73 is fixedly installed on the fixing plate 6, the guide sleeve 73 is slidably sleeved on the guide frame 74, and a limit block 75 is fixedly installed at the bottom end of the guide frame 74.
[0030] In order to guide the movement of the retaining plate 6, the guide sleeve 73 slides within the guide frame 74 to guide the retaining plate 6, so that the retaining plate 6 can only move up and down. The upper support plate 76 can limit the movement of the retaining plate 6 to prevent the retaining plate 6 from falling off.
[0031] More specifically, in this utility model, an upper support plate 76 and a lower support block 79 are fixedly installed on the other side of the bending member 1. An adjusting motor 77 is fixedly installed on the upper support plate 76. An adjusting shaft 78 is fixedly installed at the output end of the adjusting motor 77. An adjusting shaft 710 is rotatably installed on the lower support block 79. A belt pulley mechanism 711 is provided on the adjusting shaft 78 and the adjusting shaft 710. An adjusting screw 71 is fixedly installed on the belt pulley mechanism 711.
[0032] To drive the adjusting screw 71 to rotate, the rotating motor 77 rotates, which in turn drives the adjusting shaft 78 to rotate. Through the transmission action of the pulley mechanism 711, the rotation of the adjusting shaft 78 drives the adjusting shaft 710 and the adjusting screw 71 to rotate. It should be noted that the pulley mechanism 711 is an existing structure, and its specific structure is not shown.
[0033] In this utility model, specifically, the horizontal adjustment plate adjustment assembly includes a T-shaped groove 121 opened at the bottom of the lifting plate 9, a T-shaped slider 122 fixedly installed on the top of the horizontal adjustment plate 10, the T-shaped slider 122 slidably installed in the T-shaped groove 121, and a horizontal adjustment plate driving mechanism 123 provided on the lifting plate 9 and the horizontal adjustment plate 10; the horizontal adjustment plate driving mechanism 123 includes an adjustment hole 1231 opened on the lifting plate 9, a rack 1232 provided in the lifting plate 9, the rack 1232 fixedly installed on the horizontal adjustment plate 10, and a gear 1235 meshing on the rack 1232;
[0034] To adjust the horizontal position of the large curved blade 2 and position the clamping plate 5 into the slot 4, the horizontal adjustment plate drive mechanism 123 drives the horizontal adjustment plate 10 to move. The movement of the horizontal adjustment plate 10 causes the T-shaped slider 122 to slide within the T-shaped slide groove 121, which in turn moves the horizontal adjustment plate 10. The movement of the horizontal adjustment plate 10 moves the large curved blade 2, which in turn causes the clamping plate 5 to engage into the slot 4, thus positioning the large curved blade 2.
[0035] In this utility model, a drive motor 1233 and a protective cover 1236 are fixedly installed on the lifting plate 9. A drive shaft 1234 is fixedly installed at the output end of the drive motor 1233, and a gear 1235 is fixedly installed on the drive shaft 1234. The drive motor 1233 is located inside the protective cover 1236.
[0036] To drive the movement of the horizontal adjustment plate 10, the drive motor 1233 rotates, which in turn drives the drive shaft 1234 to rotate. The drive shaft 1234 rotates, which in turn drives the gear 1235 to rotate. The gear 1235 rotates, which in turn drives the rack 1232 to move. The rack 1232 moves within the adjustment hole 1231, which in turn drives the horizontal adjustment plate 10 to move. The protective cover 1236 can protect the components.
[0037] Working principle: In use, place the large curved blade 2 to be replaced on the bending table and straighten it. The extension of the hydraulic lifting arm 8 will cause the lifting plate 9 to descend, which in turn will cause the horizontal adjusting plate 10 to descend, which in turn will cause the washing plate 11 to descend. The washing plate 11 will then adhere to the flat surface at the top of the large curved blade 2. The retraction of the hydraulic lifting arm 8 will lift the large curved blade 2 upward through the washing plate 11, aligning the clamping plate 5 and the clamping slot 4. The rotation of drive motor 1233 drives drive shaft 1234 to rotate, which in turn drives gear 1235 to rotate. Gear 1235 then moves rack 1232, causing it to move within adjustment hole 1231. This movement of rack 1232 moves horizontal adjustment plate 10, which in turn moves T-slider 122 within T-groove 121. This movement of horizontal adjustment plate 10 then moves large curved blade 2, which in turn moves clamping plate 5 into slot 4, thus positioning large curved blade 2. In the initial state, fixing plate 6 is located above clamping plate 5 and does not affect the rising and moving of large curved blade 2. The rotation of adjustment motor 77 drives rotating shaft 78 to rotate. Through the transmission of pulley mechanism 711, rotating shaft 78 drives adjusting shaft 710 and adjusting screw 71 to rotate. The guide sleeve 73 slides within the guide frame 74, guiding the retaining plate 6. This allows the adjusting screw 71 to rotate, causing the screw sleeve 72 to move downwards, thus adjusting the position of the retaining plate 6. The retaining plate 6 then abuts against one side of the clamping plate 5, securing the large curved blade 2. The large curved blade 2 can then be installed at the bottom of the bending component 1. When the large curved blade 2 needs to be disassembled, the retaining plate adjusting assembly 7 adjusts the retaining plate 6 to rise and misalign with the clamping plate 5. Then, the horizontal adjusting assembly separates the clamping plate 5 from the clamping slot 4. The hydraulic lifting arm 8 places the large curved blade 2 on the bending table, and the washing disc 11 is then removed from the large curved blade 2 to complete the disassembly. This method is time-saving, labor-saving, and relatively convenient.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
