Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and specifically relates to a bending device for recycling metal fittings of household appliances. Background Art

[0002] Waste household appliances refer to discarded household electrical appliances, such as televisions, refrigerators, air conditioners, washing machines, etc. The shells of these old household appliances are usually composed of metal and plastic. Recycling them can reduce energy consumption and carbon emissions, which is of positive significance to environmental protection. For example, the recycled iron can be used to manufacture components such as new household appliance shells, and copper can be used to produce wires and electronic components, etc. After cutting and polishing the metals in waste household appliances for recycling, according to the processing requirements, a metal bending machine will be used. Metal bending refers to the process of making metal materials such as metal plates, pipes, and bars undergo bending deformation through external forces to obtain the required shape and angle. However, the existing metal bending mechanism feeds materials in parallel through a conveyor belt. When bending, the left side of the metal plate is subjected to a deforming force, which will roll up the right-side plate. During the continuous rolling process, it may cause the normal contact surface between the plate and the pressure roller to shift, resulting in problems such as inconsistent bending curvature of the metal processing and jamming of the rotating roller.

[0015] 2. The present invention has a discharging component that moves in an arc. When the stroke of the third hydraulic rod is increased, it drives the electric gripper closer to the partially bent metal plate. The electric gripper grabs it, and then the fourth motor is started to drive the U-shaped telescopic rod to rotate. The U-shaped telescopic rod will drive the third hydraulic rod to slide along the inner wall of the arc-shaped groove. During the sliding process, the stroke of the U-shaped telescopic rod will change accordingly. At this time, the electric gripper can move in the same direction as the movement direction of the metal bending, forming an accompanying clamping, reducing the risk of secondary deformation of the metal plate caused by improper clamping during discharging.

[0016] 3. The present invention is equipped with a lifting component. When it is necessary to adjust the bending curvature, the first motor can be started to drive two bevel gear sets to rotate. The bevel gear sets can thread up and down within the H-shaped plate. The T-shaped connecting block connected to the threaded rod through a bearing will also rise and fall accordingly. When the rotating roller is closer to the two driven rollers, the bending curvature is larger. When the rotating roller is farther from the two driven rollers, the bending curvature is smaller, realizing flexible adjustment of the bending curvature of the equipment.

Detailed implementation manner

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 7 shown, the embodiment of the present invention provides a bending device for recycling household appliance metal accessories, including a supporting component 1. A lifting component 2 is fixedly connected to the bottom of the supporting component 1. It also includes a linkage bending mechanism, which includes a bending component 3.

[0028] The discharging component 6 includes a fixing block 61. An arc-shaped groove 62 is penetrated and opened at a position slightly above the fixing block 61. A fourth motor 63 is fixedly installed at the bottom of the arc-shaped groove 62. The output shaft of the fourth motor 63 is fixedly connected to a U-shaped telescopic rod 64.

At this time, the left end of the metal plate can enter the gap formed by the rotating roller 32 and the driven roller 15 at a slightly inclined angle. When the metal plate is bent under force on the left side, the right side is rolled up. At this time, the bent rod 51 can rotate a certain angle in the groove in the fixed plate 41, so that the second pressing wheel 55 and the first pressing wheel 53 can always fit the metal plate, solving the problem that when bending, the force of deformation on the left side of the metal plate will roll up the plate on the right side. During the continuous rolling process, it may cause the normal contact surface of the plate and the pressing roller to shift, resulting in inconsistent bending curvatures of the bent metal and jamming of the rotating roller.

[0034] Among them, the bending assembly 3 includes two T-shaped connecting blocks 31. The bottom round rods of the two T-shaped connecting blocks 31 are fixedly connected to the two bearings 26. A roller 32 is rotatably installed at the middle position of the two T-shaped connecting blocks 31. An L-shaped plate 34 is fixedly connected to the outer edge of the bottom round rod of the right T-shaped connecting block 31. A second motor 33 is fixedly connected to the right side of the L-shaped plate 34. The right end of the output shaft of the roller 32 is fixedly connected to the second motor 33;

[0035] When the bending curvature needs to be adjusted, the first motor 22 can be started to drive the two bevel gear sets 23 to rotate. The bevel gear sets 23 can rise and fall in the inner thread of the H-shaped plate 12. The T-shaped connecting blocks 31 connected to the threaded rod 25 through the bearings 26 will also rise and fall accordingly. When the roller 32 is closer to the two driven rollers 15, the bending curvature is larger. When the roller 32 is farther from the two driven rollers 15, the bending curvature is smaller;

[0036] Among them, the feeding assembly 4 includes two fixing plates 41. Four square grooves are opened at the top of the two fixing plates 41 and are movably hinged to four bent rods 51. A plurality of round rollers 42 are rotatably installed inside the two fixing plates 41. The plurality of round rollers 42 are driven by a belt. The rotating shaft of the right round roller 42 is fixedly connected to a third motor 43. Two second hydraulic rods 44 are rotatably installed at the right bottom of the two fixing plates 41.

[0037] The third motor 43 drives the plurality of round rollers 42 to rotate clockwise. The metal plate will move from right to left on the plane composed of the fixing plates 41 and the round rollers 42. During the continuous clamping movement of the feeding assembly 4 and the pressing assembly 5, the metal plate moves. At this time, the second motor 33 is started to rotate clockwise to drive the roller 32, and the metal plate is gradually bent in the triangular area composed of one roller 32 and two driven rollers 15;

[0038] Among them, the discharging assembly 6 includes a fixing block 61. The fixing block 61 is fixedly installed on the top of the left support column 11. An arc-shaped groove 62 is penetrated through the upper position of the fixing block 61. A fourth motor 63 is fixedly installed at the bottom of the arc-shaped groove 62.

The third hydraulic rod 65 is slidably installed in the arc-shaped groove 62. The telescopic end of the third hydraulic rod 65 is fixedly connected to an electric gripper 66;

[0039] First, the stroke of the third hydraulic rod 65 is increased to drive the electric gripper 66 closer to the partially bent metal plate. The electric gripper 66 grabs it. Then, the fourth motor 63 is started to drive the U-shaped telescopic rod 64 to rotate. The U-shaped telescopic rod 64 will drive the third hydraulic rod 65 to slide along the inner wall of the arc-shaped groove 62. During the sliding process, the stroke of the U-shaped telescopic rod 64 will change accordingly. At this time, the electric gripper 66 can move in the same direction as the metal bending movement to form an accompanying clamping.

[0040] Working principle:

[0041] When using the present invention, first, the recycled waste household appliance metal plate is fed through the feeding assembly 4. The third motor 43 drives multiple round rollers 42 to rotate clockwise. The metal plate will move from right to left on the plane composed of the fixed plate 41 and the round rollers 42. During the transportation process, the top of the metal plate will be subjected to the pressing action of the pressing assembly 5. The double pressing wheel design composed of the U-shaped rod 54, the second pressing wheel 55 and the first pressing wheel 53 can rotate and move a certain distance in the groove in the fixed plate 41 under the articulated torsion action of the bent rod 51 and the spring 52. When the left side of the metal plate is about to enter the bending area of the bending assembly 3, the stroke of the two second hydraulic rods 44 is increased. The two fixed plates 41 will deflect obliquely upward to the right with the connection point of the connecting rod 45 as the axis. At this time, the left end of the metal plate can enter the gap formed by the roller 32 and the driven roller 15 at a slightly inclined angle;

[0042] During the continuous clamping movement of the feeding assembly 4 and the pressing assembly 5, the metal plate moves. At this time, the second motor 33 is started to rotate clockwise to drive the roller 32. The metal plate is gradually bent in the triangular area composed of one roller 32 and two driven rollers 15. When the metal plate is bent by the force on the left side, the right side is rolled up. At this time, the bent rod 51 can rotate a certain angle in the groove in the fixed plate 41 to make the second pressing wheel 55 and the first pressing wheel 53 always fit the metal plate;

[0043] After the metal plate is bent, it can be clamped and discharged through the two discharging assemblies 6. First, the stroke of the third hydraulic rod 65 is increased to drive the electric gripper 66 closer to the partially bent metal plate. The electric gripper 66 grabs it. Then, the fourth motor 63 is started to drive the U-shaped telescopic rod 64 to rotate. The U-shaped telescopic rod 64 will drive the third hydraulic rod 65 to slide along the inner wall of the arc-shaped groove 62. During the sliding process, the stroke of the U-shaped telescopic rod 64 will change accordingly. At this time, the electric gripper 66 can move in the same direction as the metal bending movement to form an accompanying clamping;

[0044] When the bending curvature needs to be adjusted, the first motor 22 can be started to drive the two bevel gear sets 23 to rotate. The bevel gear sets 23 can thread up and down within the H-shaped plate 12. The T-shaped connection block 31 connected to the threaded rod 25 through the bearing 26 will also rise and fall accordingly. When the roller 32 is closer to the two driven rollers 15, the bending curvature is greater. When the roller 32 is farther from the two driven rollers 15, the bending curvature is smaller. Thus, the working process ends.
