Description

Technical Field

[0001] The invention relates to the field of bending processing, and in particular to a bending device for processing household appliance accessories. Background Art

[0002] The outer covers and frames of existing home appliances are usually made of metal materials to improve the protection effect. Such home appliance accessories are all formed by bending metal plates, and a protective film will be adhered to the surface of the metal plate used for bending. In order to avoid scratches on the surface of the metal plate during the bending process, the protective film is usually not torn off when the metal plate is bent. A bending groove is pre-opened on the surface of the metal plate before bending, and the protective film is cut into multiple parts while the groove is opened. At this time, there is some excess of the protective film at the edge of the bending groove extending onto the bending groove. When the metal plate is bent, the excess protective film around the bending groove will be squeezed and clamped in the bending groove, causing the edge of the protective film to be fixed. When the protective film is subsequently cleaned, the protective film around the bending groove is difficult to clean. Summary of the invention

A mounting block 5 is fixedly connected between the two mounting blocks 103; a rubber head 5001 is arranged on the lower side of each mounting block 5; the two rubber heads 5001 are combined to form an inverted cone, and the angle of the inverted cone is less than ninety degrees; a flow groove 5002 is provided in each mounting block 5; the flow groove 5002 is externally connected to a supply pipeline; a plurality of flow holes 5003 are provided on each mounting block 5; all the flow holes 5003 are connected to the flow groove 5002; and a cutting assembly is connected to all the electric sliders 103.

[0018] It also includes a suction cup 5005; each mounting block 5 is provided with a second circulation slot 5004; the second circulation slot 5004 is located below the first circulation slot 5002; the second circulation slot 5004 is externally connected to a suction pump; a plurality of suction cups 5005 are fixedly connected to each mounting block 5; the circulation holes 5003 and the suction cups 5005 are staggered; all the suction cups 5005 are connected to the second circulation slot 5004.

[0019] The cutting assembly includes a linear drive component 21, a linear drive component 3 22, a cutter 1 231 and a cutter 2 232; each electric slider 1 103 is fixedly connected to a linear drive component 21; each output end of the linear drive component 2 21 is fixedly connected to a linear drive component 3 22; the linear drive components 3 22 on the same guide rail 1 102 are symmetrically arranged front to back; the cutter 1 231 is commonly fixedly connected between the two linear drive components 3 22 on the front side, and the cutter 2 232 is commonly fixedly connected between the two linear drive components 3 22 on the rear side; the combination of the cutter 1 231 and the cutter 2 232 is in an inverted cone, and the angle of the inverted cone is less than ninety degrees.

[0020] The upper sides of the two mounting blocks 5 match the shapes of the lower side of the upper mold 2 , thereby increasing the stability of the mounting blocks 5 and their connecting parts when the upper mold 2 moves downward.

[0021] A protective film will be adhered to the surface of the metal plate used for bending. In order to avoid scratches on the surface of the metal plate during the bending process, the protective film is usually not torn off when the metal plate is bent. A bending groove will be opened on the surface of the metal plate before bending. The protective film will be cut into multiple parts at the same time. At this time, there will be some excess of the protective film at the edge of the bending groove extending onto the bending groove. When the metal plate is bent, the excess of the protective film around the bending groove will be squeezed and clamped in the bending groove, causing the edge of the protective film to be fixed. When cleaning the protective film later, the protective film around the bending groove is difficult to clean.

[0022] In order to solve the above problems, a bending device for processing household appliance parts is provided.

[0023] The bending machine 1 of the present invention is provided with a driving assembly and a positioning assembly; the driving assembly is used to drive the upper mold 2 downward to perform mold closing and bending with the lower mold 3; the positioning assembly is used to position the bending plate 001 to be bent; the driving assembly and the positioning assembly are both existing technologies and will not be elaborated on here.

[0024] Before using the present invention, workers power the electric parts of the present invention through an external power supply; connect a supply pipe to the circulation slot 1 5002, the supply pipe supplies the degumming agent to the present invention and controls the release of the degumming agent; connect a suction pump to the circulation slot 2 5004 to provide suction force.

[0025] When the bending plate 001 is bent using the present invention, Figure 5 As shown, the worker places the bending plate 001 on the lower mold 3 and positions it through the positioning assembly, and then controls the driving assembly to drive the upper mold 2 and the parts thereon to move downward until the two rubber heads 5001 are stuck in the bending grooves of the bending plate 001, as shown in FIG. Figure 8 As shown, the angle of the bending groove is ninety degrees, while the angle of the inverted cone formed by the combination of the two rubber heads 5001 is less than ninety degrees. Then, the two electric sliders 103 on the same guide rail 102 are controlled to move away from each other, thereby driving the two mounting blocks 5 to move away from each other. At this time, the rubber head 5001 forms friction with the edges of the protective film on both sides of the bending groove, and drives the protective film to be torn to both sides, so as to avoid the excess protective film around the bending groove being squeezed and clamped in the bending groove during bending, resulting in the edge of the protective film being fixed, and the protective film around the bending groove being difficult to clean; the rubber head 5001 is made of deformable material, and can be moved out of the bending groove during movement.

[0026] While the rubber head 5001 tears the protective film to both sides, it controls the external supply pipeline to supply the degumming agent into the circulation groove 5002. The degumming agent is distributed to each circulation hole 5003 through the circulation groove 5002, and then flows out through the opposite surfaces of the two mounting blocks 5, flows down along the surface of the rubber head 5001 to the bending plate 001, flows from the edge of the torn protective film to between the protective film and the bending plate 001, reacts with the glue of the protective film, and facilitates the subsequent tearing off of the protective film from the edge of the protective film.

[0027] It should be noted that the debonding agent flowing out of the circulation hole 5003 is small in quantity. After flowing onto the bending plate 001, the fluidity is low, and a large amount of debonding agent will not be scattered and adhere to the equipment.

[0028] After the rubber head 5001 tears the protective film to both sides, it controls the linear drive member 101 to contract, driving the mounting frame 4 and the parts thereon to move upward. At this time, the driving assembly synchronously drives the upper mold 2 to move downward until the two mounting blocks 5 are distributed on the front and rear sides of the upper mold 2. Fig.11 As shown, the upper mold 2 continues to move downward to cooperate with the lower mold 3 to extrude and bend the bending plate 001, and then the upper mold 2 is controlled to move upward and reset, and the worker takes off the bent bending plate 001, thereby completing the bending work.

[0029] During the metal plate bending process, there is a possibility that the metal plate will be broken. When the metal plate is pressed by the mold, the worker cannot judge whether the metal plate is broken. When the mold is out of contact with the metal plate, the metal plate loses its fixation, and the broken metal plate will fall to both sides, which may easily endanger the safety of the workers and the bending equipment.

[0030] After bending and deformation of bending plate 001, Fig.11 As shown, the two sides are flipped upwards, at this time, the two sides of the bending plate 001 are in contact with the adjacent suction cups 5005 respectively, and the suction force of the external suction pump is distributed to each suction cup 5005 through the circulation groove 2 5004, and then each suction cup 5005 adsorbs and fixes the bending plate 001 on the adjacent side, and then the upper mold 2 is controlled to move upward to break away from the bending plate 001, and at the same time, the linear drive member 101 extends out, so that the mounting frame 4 and the mounting block 5 maintain the current height, and the suction cup 5005 continues to adsorb and fix the bending plate 001. After the upper mold 2 is separated, the worker observes whether the bending plate 001 is broken. If a break occurs, the worker holds and fixes the bending plates 001 on both sides, and then controls the external suction pump to stop working, the suction cup 5005 releases the fixation of the bending plate 001, and the linear drive component 101 drives the mounting frame 4 and the related zero line to move up, and the worker removes the bending plate 001; in summary, the bending plate 001 is adsorbed and fixed by the suction cup 5005 when the upper mold 2 is separated from the bending plate 001, so as to prevent the bending plate 001 from losing its fixation when the upper mold 2 is separated from the bending plate 001, and the bending plate 001 broken into two halves will fall to both sides, which may easily endanger the safety of workers and bending equipment.

[0031] Before some metal plates are bent, bending grooves are not pre-opened, so the protective film at the bending grooves is not cut. After bending, the protective film will be squeezed at the bending position, which is difficult to clean later. Therefore, before the rubber head 5001 contacts the bending plate 001, the cutter 1 231 and the cutter 2 232 first contact the protective film on the upper side of the bending plate 001. At this time, the linear drive member 2 21 on the left is controlled to extend to the left, and the linear drive member 2 21 on the right is contracted to the right, and then all the linear drive members 3 22 move to the left as a whole. The linear drive member 3 22 drives the cutter 1 231 and the cutter 2 232 to move to the left, and then the telescopic state of the left and right linear drive members 2 21 is reversed to change the cutter The first 231 and the second cutter 232 move in the same direction, and the same process is repeated for many times. The first cutter 231 and the second cutter 232 move back and forth on the protective film on the upper side of the bending plate 001 to cut an opening on the upper protective film. After the opening is cut, each electric slider 103 is controlled to drive the first cutter 231 and the second cutter 232 to move away from each other in the front and rear directions, and the cut protective film opening is separated to the front and rear sides respectively to form a space that can accommodate the inverted cone structure formed by the two rubber heads 5001. Then, each linear drive member 3 22 is controlled to contract and drive the first cutter 231 and the second cutter 232 to move upward respectively. Then, each electric slider 103 drives the two mounting blocks 5 to approach each other and fit together. Figure 8 As shown, the rubber head 5001 is moved down to the incision of the protective film, and the protective film is further torn to both sides and the debonding agent is added; thereby, the protective film on the upper surface of the bending plate 001 without the bending groove is cut open by the cutter 1 231 and the cutter 2 232 to avoid the protective film at the bending position not being cut open. After bending, the protective film will be squeezed at the bending position, which will be difficult to clean later.

[0032] It should be noted that all the linear drive components of the present invention are electric push rods.

[0033] Example 2 On the basis of Example 1, Figure 3-Figure 5 and Fig.13 As shown, it also includes a linear drive component 4 31, a linear drive component 5 32 and a cutter 3 33; a linear drive component 4 31 is fixedly connected to the left and right sides of the lower mold 3; each linear drive component 4 31 output end is fixedly connected to a linear drive component 5 32; all linear drive components 5 32 output ends are commonly fixedly connected to a cutter 3 33; the cutter 3 33 is received in the groove of the lower mold 3.

[0034] Since the bending plate 001 has a pre-bending groove on only one side, and the bending plate 001 is usually covered with protective films on both the upper and lower surfaces, the protective film on the lower surface is stretched and deformed from the bending position after the bending plate 001 is bent, causing the protective film to be more tightly attached to the bending plate 001, increasing the difficulty of subsequent removal.

[0035] When the bending plate 001 is placed on the lower mold 3 and positioned, the protective film on the upper surface of the bending plate 001 is processed by the cutting assembly, such as Fig.13 As shown, the two linear drive members five 32 are controlled to extend upward, pushing the cutter three 33 to move upward until it contacts the protective film on the lower surface of the bending plate 001 and then stops rising; then the two linear drive members four 31 are controlled to reciprocate and extend in the same direction, driving the two linear drive members five 32 and the cutter three 33 to move back and forth left and right, thereby the lower cutter three 33 synchronously cuts the protective film on the lower surface and the upper surface of the bending plate 001 with the cutting component on the upper side; when the bending plate 001 is bent, at this time, the protective film on the lower surface has been cut into two parts at the bending position, and the protective film on the lower surface will be stretched and deformed from the bending position, and then separated to both sides of the cutting opening, and the cutting opening is enlarged, thereby facilitating the subsequent tearing off of the protective film and reducing the difficulty of removal.

[0036] Example 3 On the basis of Example 2, Figure 3-Figure 5 and Figure 14-15 As shown, it also includes a clamping unit, which includes a fixed block 41, an electric shaft 42, a supporting plate 43, a linear drive member 6 44 and a limit plate 45; a fixed block 41 is fixedly connected to the left and right sides of the lower mold 3; each fixed block 41 is rotatably connected to an electric shaft 42; the electric shaft 42 is driven by a motor; each electric shaft 42 is fixedly connected to a supporting plate 43; each supporting plate 43 is provided with a waste groove 4301; each supporting plate 43 is fixedly connected to a number of linear drive members 6 44; each supporting plate 43 is slidably connected to a limit plate 45; the limit plate 45 is L-shaped; a channel is formed between the supporting plate 43 and the limit plate 45; the limit plate 45 is fixedly connected to the output ends of all the linear drive members 6 44 on the corresponding supporting plate 43.

[0037] Ball bearings are arranged on the opposite surfaces of the supporting plate 43 and the limiting plate 45 to reduce the friction with the bending plate 001 .

[0038] The front side edges of the supporting plate 43 and the limiting plate 45 relative to each other are rounded to facilitate guiding the bending plate 001 into the channel between the supporting plate 43 and the limiting plate 45 .

[0039] The clamping unit also includes a collecting box 46, a guide rail 47, an electric slider 48 and a scraper 49; each supporting plate 43 is connected to a collecting box 46 on its lower side; the collecting box 46 is connected to the channel between the supporting plate 43 and the limiting plate 45 through a waste trough 4301; each collecting box 46 is provided with a connecting port 4601; a suction pump is externally connected to the connecting port 4601; each limiting plate 45 is fixedly connected to a guide rail 47; the guide rail 47 is located in the channel between the supporting plate 43 and the limiting plate 45; each guide rail 47 is slidably connected to an electric slider 48 on its lower side; each electric slider 48 is fixedly connected to a scraper 49 on its lower side.

[0040] The collection box 46 is detachably connected to the support plate 43; when the metal wire is stuck in the collection box 46 and cannot be withdrawn through the connection port 4601, the collection box 46 can be removed to clean the internal metal wire.

[0041] When the metal plate is bent, the worker holds both sides of the metal plate. At the moment of bending, the metal plate on the worker's side will be folded toward the upper mold 2. At this time, the worker's hands will be driven by the folded metal plate to move to the upper mold 2. When the folded metal plate contacts the upper mold 2, the worker's hands are located between the metal plate and the upper mold 2, and are easily squeezed and injured.

[0042] Before the bending work is carried out, the clamping unit is in the initial state, the upper surface of the supporting plate 43 is flush with the upper surface of the lower mold 3, and when the bending plate 001 is placed, the worker controls the linear drive member 6 44 to contract, so that the limit plate 45 slides upward on the supporting plate 43, and the channel formed by the supporting plate 43 and the limit plate 45 is expanded to the maximum, and then the worker pushes the bending plate 001 into the bending machine 1 from front to back, and the two sides of the bending plate 001 enter the corresponding channels, and the supporting plate 43 supports the lower side of the bending plate 001, and then the linear drive member 6 44 is controlled to extend again, pushing the limit plate 45 to move downward, reducing the upper and lower distances of the channel, and the lower surface of the limit plate 45 contacts the upper surface of the bending plate 001, and then the bending plate 001 is opened. The two sides of the bending plate 001 are clamped and fixed by the supporting plate 43 and the limiting plate 45. The worker only needs to continuously push the bending plate 001 toward the bending machine 1 without holding the two sides of the bending plate 001 with both hands, so as to avoid the worker's hands being located between the bending plate 001 and the upper mold 2 when the folded bending plate 001 contacts the upper mold 2, which may cause the worker to be squeezed and injured. When the bending plate 001 is bent and flipped, the electric shaft 42 drives the supporting plate 43 and the parts thereon to follow the flipping, thereby always keeping the two sides of the bending plate 001 clamped and fixed. After the bending is completed, the channel between the supporting plate 43 and the limiting plate 45 is controlled to expand to the maximum, and the clamping of the bending plate 001 is released, so that the worker removes the bent plate 001.

[0043] The pre-bending grooves are cut and grooved in the metal plate in the left and right directions, so some metal filaments produced by the grooves will remain on both sides of the bending grooves. The filaments are light and easy to deform. They are easy to get stuck in the bending grooves during the bending process, affecting the bending angle of the metal plate. At the same time, when the workers remove the metal plate, if the workers operate with bare hands, they are easily scratched by the metal wires; when the workers operate with gloves, the metal wires are easy to catch the gloves, and the metal wires and gloves are pulled, affecting the angle of the metal plate after bending.

[0044] Before placing the bending plate 001, the worker connects an external suction pump to the two connection ports 4601. The suction force is filled into the channel between the supporting plate 43 and the limiting plate 45 through the waste tank 4301 via the collection box 46. After the worker clamps the bending plate 001 through the supporting plate 43 and the limiting plate 45, the worker controls the two electric sliders 48 to approach the two sides of the bending plate 001 along the guide rails 47 according to the width parameters on both sides of the bending plate 001, so that the two scrapers 49 are close to the two sides of the bending plate 001. When the worker pushes the bending plate 001 toward the bending machine 1, the scrapers 49 The filamentary objects remaining on both sides of the bending plate 001 are scraped off. At the same time, the suction force of the suction pump sucks the scraped metal wires into the collection box 46 through the waste groove 4301, and is sucked away through the suction pump connected to the connection port 4601, thereby removing the metal wires remaining on both sides of the bending plate 001, avoiding the metal wires from being stuck in the bending groove and affecting the bending angle of the bending plate 001, and preventing the workers from being scratched by the metal wires when removing the bending plate 001 with their bare hands, and the workers wearing gloves when operating, causing the metal wires to pull against the gloves, affecting the angle of the bending plate 001 after bending.
