Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to a bending device for hardware processing. Background Technology

[0002] Hardware refers to small accessories or components made of metal materials, including steel, copper, and aluminum. Common types include screws, nuts, hinges, handles, door locks, and hooks, which are widely used in construction, furniture, machinery, electronics, and other fields, serving to connect, fix, support, or decorate. Some hardware (such as corner brackets) require bending at angles during processing, thus necessitating the use of bending devices.

[0003] When using existing bending devices, workers need to manually place the metal sheet on the V-shaped base, then apply pressure to it using the V-shaped bending head to achieve the bending purpose, and then manually remove the processed workpiece. However, this manual loading and unloading method not only significantly reduces processing efficiency and increases labor costs, but also poses a risk of hand injury due to misoperation during the loading and unloading process. Utility Model Content

[0004] The purpose of this utility model is to provide a corner bending device for hardware processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A metalworking angle-bending device includes a base plate. A first electric push rod is mounted on the upper surface of the base plate via a translation mechanism. A suspension plate is mounted at the telescopic end of the first electric push rod, and suction cup assemblies are provided at both ends of the suspension plate along its length.

A hydraulic cylinder is mounted on the upper surface of the second U-shaped frame. The end of the hydraulic cylinder extends through to the lower side of the second U-shaped frame and is mounted on a horizontal plate. Two V-shaped bends are symmetrically distributed on the lower surface of the horizontal plate.

[0009] Furthermore, the feeding mechanism includes two baffles mounted on the upper surface of the base plate.

[0010] Furthermore, the top material mechanism includes a third U-shaped frame installed on the outer surface of the V-shaped base. A second electric push rod is installed on the outer surface of the third U-shaped frame. A top rod is installed at the end of the telescopic end of the second electric push rod, and the top rod corresponds to the V-shaped angle of the V-shaped base.

[0011] Furthermore, guide posts are installed on both sides of the upper surface of the horizontal plate, and the ends of the guide posts slide through to the upper side of the second U-shaped frame.

[0012] Furthermore, a control panel is mounted on the outer surface of the first U-shaped frame, and the first electric push rod, the first servo motor, the hydraulic cylinder, the second servo motor, and the second electric push rod are all electrically connected to the control panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0021] 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.

[0022] like Figure 1-5 As shown, a metalworking angle-folding device includes a base plate 1. A first electric push rod 101 is mounted on the upper surface of the base plate 1 via a translation mechanism 2. A suspension plate 102 is mounted at the telescopic end of the first electric push rod 101. Suction cup assemblies 103 are provided at both ends of the suspension plate 102 along its length. Two support columns 104 are mounted on the upper surface of the base plate 1 along one side of its length direction. The two support columns 104 are symmetrically distributed on both sides of the translation mechanism 2 along its width direction. A V-shaped base 105 is mounted on the top of the support columns 104. Two V-shaped angle-folding heads 106 are mounted on the upper surface of the base plate 1 above the V-shaped base 105 via a lifting mechanism 3. Two sets of feeding mechanisms 4 are provided on the upper surface of the base plate 1 along the other side of its length direction. The two sets of feeding mechanisms 4 are symmetrically distributed on both sides of the translation mechanism 2 along its width direction. A top-feeding mechanism 5 is provided on the outer surface of the V-shaped base 105.

[0023] In use, the translation mechanism 2 moves the suction cup assembly 103 horizontally to directly above the feeding mechanism 4. Then, the first electric push rod 101 lowers the suction cup assembly 103 to adsorb the metal sheet on the feeding mechanism 4. Next, the first electric push rod 101 rises and, using the translation mechanism 2, moves the metal sheet horizontally to directly above the V-shaped base 105. Subsequently, the first electric push rod 101 lowers the metal sheet to the surface of the V-shaped base 105, breaking the vacuum in the suction cup assembly 103, allowing the metal sheet to be placed on the V-shaped base 105. 05. Next, the suction cup assembly 103 returns to the top of the feeding mechanism 4 to adsorb the metal sheet. At the same time, the lifting mechanism 3 drives the V-shaped bending head 106 to descend and cooperate with the V-shaped base 105 to complete the bending. Then, the ejector mechanism 5 ejects the bent workpiece from the V-shaped base 105, thereby achieving the purpose of automatic loading and unloading. It can process two metal sheets at a time, which is not only more efficient but also reduces labor costs. It also avoids the risk of hand injury due to manual loading and unloading errors, thus improving safety.

[0024] Preferably, the translation mechanism 2 includes a first U-shaped frame 201 mounted on the upper surface of the base plate 1. A limit rod 202 is installed between the inner walls of the two sides of the first U-shaped frame 201. A drive plate 203 is slidably mounted on the outer surface of the limit rod 202, and a first electric push rod 101 is mounted on the lower surface of the drive plate 203. A first threaded rod 204 is rotatably mounted between the inner walls of the two sides of the first U-shaped frame 201, and the first threaded rod 204 passes through the interior of the drive plate 203 and is threadedly connected to it. A first servo motor 205 is mounted on the outer surface of the first U-shaped frame 201, and the output shaft of the first servo motor 205 is connected to the first threaded rod 204.

[0025] When the first servo motor 205 is started, it drives the first threaded rod 204 to rotate. Since the limiting rod 202 limits the drive plate 203, the drive plate 203 can be driven to move along the length direction of the first threaded rod 204 under the drive of the threaded connection, and achieve the purpose of driving the first electric push rod 101 and the suction cup assembly 103 to move horizontally.

[0026] Preferably, the lifting mechanism 3 includes a second U-shaped frame 301 mounted on the upper surface of the base plate 1. A hydraulic cylinder 302 is mounted on the upper surface of the second U-shaped frame 301. The end of the extension and retraction end of the hydraulic cylinder 302 extends through to the lower side of the second U-shaped frame 301 and is mounted on a horizontal plate 303. Two V-shaped bend heads 106 are symmetrically distributed on the lower surface of the horizontal plate 303.

[0027] When the hydraulic cylinder 302 is activated, its telescopic end causes the horizontal plate 303 to descend, which in turn causes the V-shaped bending head 106 to cooperate with the V-shaped base 105 to complete the bending of the metal sheet.

[0028] Preferably, the feeding mechanism 4 includes two baffles 401 mounted on the upper surface of the base plate 1. A fixing block 402 is mounted on the upper side of the outer surface of one of the baffles 401, and a second servo motor 403 is mounted on the upper surface of the fixing block 402. The output shaft of the second servo motor 403 is connected to a second threaded rod 404, and the end of the second threaded rod 404 is rotatably connected to the upper surface of the base plate 1. A nut seat 405 is mounted on the outer surface of the second threaded rod 404. A through groove 406 is formed on the outer surface of the baffle 401 along its height direction. A lifting plate 407 is provided between the two baffles 401, and one side of the lifting plate 407 passes through the through groove 406 and connects to the nut seat 405.

[0029] Workers neatly stack metal sheets on the lifting plate 407. The limiting effect of the baffles 401 on both sides keeps the metal sheets in a neat state. Since the suction cup assembly 103 has a certain deformation capability, even if there is a certain height difference in the top layer of metal sheets, they can still be attracted by the suction cup assembly 103.

[0030] Therefore, by starting the second servo motor 403, the second servo motor 403 drives the second threaded rod 404 to rotate. Under the limiting action of the through groove 406, the nut seat 405 can drive the lifting plate 407 to rise slowly, thereby compensating for the height difference of the uppermost metal sheet being taken away, so that the suction cup group 103 can pick up the uppermost metal sheet every time.

[0031] Workers only need to replenish materials periodically, and one worker can oversee several machines, thereby reducing labor costs.

[0032] It is worth noting that the rising speed of the lifting plate 407 is adjusted according to the thickness of the metal sheet.

[0033] Preferably, the top material mechanism 5 includes a third U-shaped frame 501 installed on the outer surface of the V-shaped base 105. A second electric push rod 502 is installed on the outer surface of the third U-shaped frame 501. A top rod 503 is installed at the end of the telescopic end of the second electric push rod 502. The top rod 503 corresponds to the V-shaped angle of the V-shaped base 105.

[0034] After the metal sheet completes the bend within the V-shaped base 105, the V-shaped metal sheet adheres to the inner wall of the V-shaped base 105. At this point, the second electric push rod 502 can be activated, which drives the push rod 503 to extend, thereby pushing the bendable metal sheet off the V-shaped base 105 and achieving automatic unloading.

[0035] Workers only need to place a collection box at the location where the workpiece falls to collect it.

[0036] Preferably, guide posts 304 are installed on both sides of the upper surface of the horizontal plate 303, and the ends of the guide posts 304 slide through to the upper side of the second U-shaped frame 301.

[0037] The guide column 304 makes the horizontal plate 303 more stable when it is raised and lowered, ensuring the quality of the bend.

[0038] Preferably, a control panel 6 is mounted on the outer surface of the first U-shaped frame 201, and the first electric push rod 101, the first servo motor 205, the hydraulic cylinder 302, the second servo motor 403, and the second electric push rod 502 are all electrically connected to the control panel 6.

[0039] The control panel 6 allows for unified control and parameter adjustment of the entire equipment, achieving automated processing and reducing manual intervention.
