Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware manufacturing technology, specifically to a hardware stamping bending machine. Background Technology
[0002] After production, copper connectors need to be bent into suitable shapes.
[0003] Chinese patent application number 202021921273.7 discloses a pinion rack bending mechanism, including a base with a rack inside. The rack moves only along its own length, and one end of the rack is equipped with a cylinder for driving its movement. A gear meshing with the rack is connected to the base, and the gear is connected to a flipping shaft for bending the product. The gear drives the flipping shaft to rotate and flip the product. An angle limiting block is detachably connected to the flipping shaft, and the positions where the end faces of the angle limiting block abut against the sides of the base correspond to the positions of the flipping shaft before and after bending. This mechanism effectively avoids problems such as delamination and cracking of the sheet metal, greatly improves production yield, reduces manpower and material resources, and reduces enterprise expenses.
[0004] However, Chinese Patent 0027 with application number 202021921273.7 states that "the drive end is detachably connected to an angle limiting block 41 after penetrating the base 1. The angle limiting block 41 is an arc-shaped block, and the position of the flip shaft 4 before and after flipping corresponds to the position where the two end faces of the angle limiting block 41 abut against the top surface of the base 1." In other words, the flip shaft is connected to both the angle limiting block and the gear. When replacing the flip shaft, the gear and the retaining ring need to be removed simultaneously, which is quite troublesome overall.
[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] like Figures 1 to 5 As shown, the present invention relates to a metal stamping bending machine, comprising: a turntable 1 and a bending assembly 2, wherein a carrier 3 is mounted on the turntable 1 and the product is placed on the carrier 3.
[0027] Turntable 1 drives carrier 3 to move. When the product moves to bending component 2, bending component 2 bends the product.
[0028] The bending assembly 2 includes: a pressing member 4, a fixing frame 5, a rotating shaft 6 that rotates on the fixing frame 5, a power source 7 that drives the rotating shaft 6 to rotate, a bushing 8 that is detachably connected to the rotating shaft 6, and a flipping member 9 that is fixedly connected to the bushing 8; when the rotating shaft 6 rotates, it drives the flipping member 9 to flip, thereby bending the product.
[0029] In one embodiment, the rotating shaft 6 has a threaded hole, and the bushing 8 has a through hole. The bushing 8 is fixed by a screw 10 passing through the through hole and locking into the threaded hole, thereby realizing the disassembly of the bushing 8.
[0030] The power source 7 includes a first cylinder 11, a rack 12 connected to the first cylinder 11, and a gear 13 fixedly mounted on the rotating shaft 6, wherein the rack 12 meshes with the gear 13.
[0031] In the application, two products are placed on the carrier 3, and the number of flipping parts 9 must match the number of products; the fixing frame 5 is connected to a second cylinder 14 that moves it closer to or away from the products, that is, the fixing frame 5 is connected to the piston rod of the second cylinder 14; the first cylinder 11 is fixedly installed on the fixing frame 5, and a first guide rail slider is provided between the rack 12 and the fixing frame 5, so that the rack 12 can move up and down stably; the second cylinder 14 is fixedly installed on the first slide cylinder 15, and the first slide cylinder 15 drives the second cylinder 14 closer to or away from the turntable 1.
[0032] To secure the product during bending, a third cylinder 16 is connected to the pressing member 4. The first cylinder 11 drives the pressing member 4 to approach the product and press it into close contact with the carrier 3. The carrier 3 has a contour cavity. The pressing member 4 causes part of the product to bend within the contour cavity, completing the first bend and forming the first bend, thus securing the product from the middle. The first slide cylinder 15 drives the second cylinder 14 to approach the turntable 1. Then, the second cylinder 14 drives the flipping member 9 to move upward until the product contacts the abutment fixed on the pressing member 4, forming the second bend. Then, the first slide cylinder 15 drives the second cylinder 14 away from the turntable 1, adjusting the position of the flipping member 9. Then, the rotating shaft 6 rotates, causing the flipping member 9 to flip, bending the product and forming the third bend.
[0033] It should be added here that the third cylinder 16 is connected to a stroke cylinder 17, and the stroke cylinder 17 is connected to a second slide cylinder 18.
[0034] The carrier 3 includes: a fixing member 19 fixedly installed on the turntable 1, and a cover 20 rotatably installed on the turntable 1. The cover 20 and the fixing member 19 are connected by a torsion spring. A magnetic suction member 21 is installed on the cover 20. The magnetic suction member 21 is preferably MISUMI-HXCC10, which has high reliability.
[0035] Below the turntable 1 is an opening assembly for controlling the rotation of the flipping component 9; the opening assembly includes: a fourth cylinder 22, a connecting rod mounted on the piston rod of the fourth cylinder 22, and a roller 23 mounted on the end of the connecting rod.
[0036] When the fourth cylinder 22 drives the connecting rod to move upward, the roller 23 rolls on the cover 20. The connecting rod continues to move upward, which compresses the torsion spring and opens the cover 20.
[0037] Working principle:
[0038] The rotating shaft 6 has a threaded hole, and the bushing 8 has a through hole. The bushing 8 is fixed by a screw 10 passing through the through hole and locking into the threaded hole, thereby realizing the disassembly of the bushing 8.
[0039] The first cylinder 11 drives the pressing member 4 to approach the product and press the product to make it in close contact with the carrier 3. The carrier 3 is provided with a contour cavity. The pressing member 4 causes part of the product to bend in the contour cavity, completing the first bend and forming the first bend. The product is then fixed from the middle. The first slide cylinder 15 drives the second cylinder 14 to approach the turntable 1. Then the second cylinder 14 drives the flipping member 9 to move upward until the product contacts the abutment fixed on the pressing member 4, forming the second bend. Then the first slide cylinder 15 drives the second cylinder 14 away from the turntable 1 to adjust the position of the flipping member 9. Then the rotating shaft 6 rotates to flip the flipping member 9, bending the product and forming the third bend.
