[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] like Figures 1 to 13 As shown, the sheet metal processing and bending equipment with adjustable bending section described in the present invention includes a fixed seat 3; a bending mechanism is arranged on the fixed seat 3; the bending mechanism is composed of two forming components 1; the forming component 1 includes a first fixed plate 101, a fixed shaft 107 fixed on the first fixed plate 101, a fixed forming rod 104 fixed on the fixed shaft 107 and a turntable 105 rotatably connected to the fixed shaft 107; a dynamic forming rod 103 is fixed at an eccentric position of the turntable 105; a gear 106 coaxially arranged with the fixed shaft 107 is fixed on the turntable 105.

[0044] A disc 102 is fixed on the first fixing plate 101; a positioning block 102a is provided on the side wall of the disc 102; a circular hole 302 used in pair with the disc 102 is provided on the fixing seat 3; a plurality of slots 302a matching the positioning block 102a are provided on the inner side wall of the circular hole 302; the slots 302a are distributed in a circle; and a through hole 301 is provided on the fixing seat 3.

[0045] The disc 102 is inserted into the circular hole 302; the positioning block 102a is inserted into one of the slots 302a; a threaded hole 101a is provided on the first fixing plate 101, and a bolt passes through the through hole 301 and is threadedly connected with the threaded hole 101a.

[0046] The fixing seat 3 is provided with a molded power assembly 4 for driving the two gears 106 to move; the rotating disk 105 is connected to the fixing shaft 107 via a bearing 108; and the width of the through hole 301 is equal to the diameter of the bolt.

[0047] The gap formed by the movable forming rod 103 and the fixed forming rod 104 on the same forming assembly 1 is a metal sheet positioning groove. After one of the forming assemblies 1 is rotated 180 degrees, the two metal sheet positioning grooves are still aligned to ensure that the metal sheet can be inserted into and pass through the two metal sheet positioning grooves; the movable forming rod 103 and the fixed forming rod 104 are round rod structures.

[0048] Product bending process: the end of the metal sheet released by the external unwinding mechanism for unwinding enters the two metal sheet positioning grooves and then reaches the set position; the external cutting mechanism cuts the metal sheet, and the cut part of the metal sheet remains in the metal sheet positioning groove; then the forming power component 4 drives the two gears 106 to move, so that the movable forming rods 103 on the two turntables 105 swing around the fixed forming rods 104, and the metal sheet is bent and formed around the fixed forming rods 104 by the movable forming rods 103.

[0049] When a product of another shape needs to be processed, one of the forming components 1 is removed and turned 180 degrees. While ensuring that the two positioning grooves are still aligned, the arrangement positions of the movable forming rod 103 and the fixed forming rod 104 of the forming component 1 are changed to achieve the switching of the formed product.

[0050] like Fig.12 As shown, the two forming components 1 are arranged in the same direction. The first state diagram is the initial state diagram of the movable forming rod 103 rotating. When the movable forming rod 103 rotates at four different angles, four different shapes of products can be formed. Fig.13As shown, the two forming components 1 are arranged in different directions. The first state diagram is an initial state diagram in which the movable forming rod 103 is not rotated. When the movable forming rod 103 is rotated at four different angles, four other products of different shapes can be formed.

[0051] As a preferred embodiment of the present invention, the molding power assembly 4 includes a rack fixing seat 404 slidably connected to the fixing seat 3, and a molding cylinder 401 with one end fixed on the fixing seat 3; the other end of the molding cylinder 401 is fixed to the rack fixing seat 404; a first connecting plate 407 and a second connecting plate 408 are fixed on the rack fixing seat 404; the second connecting plate 408 is arranged between the two molding assemblies 1.

[0052] A plurality of first teeth 407a are evenly distributed on the first connecting plate 407; a plurality of second teeth 408a are evenly distributed on both sides of the second connecting plate 408; the first teeth 407a and the second teeth 408a are arranged along the sliding direction of the rack fixing seat 404; the second connecting plate 408 is staggered with the first connecting plate 407; one of the forming components 1 is arranged between the first tooth 407a and the second tooth 408a opposite to the first tooth 407a; the second tooth 408a on the other side is meshed with the gear 106 of another forming component 1; a slider 4010 is fixed on the rack fixing seat 404; and a guide rail 409 matching the slider 4010 is fixed on the fixing seat 3.

[0053] When two molding components 1 are arranged in the same direction:

[0054] The two gears 106 are arranged symmetrically, and the second teeth 408a on both sides are respectively meshed with the gears 106 of the two forming components 1; the first teeth 407a are not connected to the gears 106. When the forming cylinder 401 drives the rack fixing seat 404 to move, it drives the first connecting plate 407 to move; the second teeth 408a on both sides respectively drive the gears 106 on both sides to rotate, so that the turntables 105 on both sides swing in different directions, bending the metal sheet into an elliptical product.

[0055] A forming component 1 between the first connecting plate 407 and the second connecting plate 408 is removed and turned 180 degrees, and the two gears 106 are arranged asymmetrically up and down; the gear 106 of the forming component 1 after the angle change is separated from the second tooth 408a and meshed with the first tooth 407a. When the rack fixing seat 404 moves, the second tooth 408a drives the other forming component 1 that has not been turned to rotate, and the first tooth 407a drives the forming component 1 that has been turned 180 degrees to rotate, and one end of the metal plate is bent upward and the other end is bent downward to form an S-shaped product.

[0056] As a preferred embodiment of the present invention, a second sliding sleeve 405 is fixed on the rack fixing seat 404; a sliding rod 406 slidingly connected to the second sliding sleeve 405 is fixed on the first connecting plate 407; a first nut 403 is fixed on the second sliding sleeve 405; an adjusting bolt 402 is threadedly connected to the first nut 403; the adjusting bolt 402 is rotatably connected to the sliding rod 406; a guide strip is provided on the sliding rod 406 to ensure that the sliding rod 406 does not rotate in the second sliding sleeve 405; rotating the adjusting bolt 402 can drive the sliding rod 406 and the first connecting plate 407 to slide along the second sliding sleeve 405.

[0057] When the second tooth 408a is connected to two gears 106 at the same time, the position of the first connecting plate 407 is adjusted by rotating the adjusting bolt 402, so that the first tooth 407a can be separated from the gear 106 to prevent interference.

[0058] In addition, because after the gear 106 is meshed with the first tooth 407a, the movable forming rod 103 and the fixed forming rod 104 are not necessarily on the same vertical line, the two positioning grooves may not be aligned, and material jamming is likely to occur during feeding; therefore, after the forming component 1 is turned one hundred and eighty degrees, the gear 106 of the forming component 1 is preferentially meshed with the first tooth 407a, and then the position of the first connecting plate 407 can be adjusted by rotating the adjusting bolt 402, so that the movable forming rod 103 and the fixed forming rod 104 are on the same vertical line, and the two positioning grooves are aligned, so as to prevent the metal sheet from getting stuck in the positioning groove and ensure smooth feeding.

[0059] As a preferred embodiment of the present invention, it also includes a frame 5; the number of the fixed seat 3 and the bending mechanism are both two; the fixed seats 3 are arranged oppositely; a second fixed plate 8 is fixed between the two fixed seats 3; a guide column 7 is fixed on the frame 5; a guide sleeve 9 slidably connected to the guide column 7 is fixed on the fixed seat 3; a linear module 6 is connected between the frame 5 and the fixed seat 3; a discharge assembly 2 for pushing the formed product out of the bending mechanism is arranged on the frame 5; the two bending mechanisms are also arranged oppositely, and the input port of the metal sheet is between the two bending mechanisms.

[0060] The linear module 6 starts, driving the two fixed seats 3 to move in the same direction, so that the positioning grooves of the first bending mechanism are aligned, and the unwinding mechanism feeds the metal sheet into the positioning groove of the first bending mechanism and cuts it off; the linear module 6 moves again, and the end of the metal sheet on the unwinding mechanism is misaligned with the positioning groove of the first bending mechanism, and the bending mechanism begins to bend and form the cut-out part. During the forming process, the unwinding mechanism continues to unwind the material, and as the fixed seat 3 moves, the metal sheet on the unwinding mechanism is stuck in the positioning groove of the other bending mechanism (due to the rigidity of the metal sheet, the protruding part at the end can still remain straight). By moving the fixed seat 3, the two bending mechanisms can be fed alternately, shortening the processing time and improving the forming efficiency.

[0061] As a preferred embodiment of the present invention, the discharging assembly 2 includes a straight rod 201 fixed on the frame 5; two first sliding sleeves 204 are fixed on the straight rod 201; a push rod 202 is hinged at the bottom of the first sliding sleeve 204; a baffle 205 is fixed to one end face of the first sliding sleeve 204; the baffle 205 is arranged on the swinging path of the push rod 202; the two first sliding sleeves 204 are arranged along the length direction of the guide column 7; the push rod 202 is arranged between the two forming assemblies 1 of the same bending mechanism; since the dynamic forming rods 103 swing outward, they will not contact the push rod 202.

[0062] When the fixed seat 3 slides, the push rod 202 moves relative to the forming assembly 1, and the push rod 202 can enter or leave the gap between the two forming assemblies 1. When the bending mechanism is in the feeding state, the fixed seat 3 moves relative to the frame 5, and the push rod 202 enters the gap between the two forming assemblies 1. When the push rod 202 contacts the metal sheet, since the blocking bar 205 does not generate a thrust on the push rod 202, the metal sheet pushes the push rod 202 to flip outward until the push rod 202 bypasses the metal sheet and enters the other side of the metal sheet.

[0063] When the forming assembly 1 forms the metal sheet, although the fixed seat 3 moves relative to the frame 5, the push rod 202 will not contact the metal sheet before the product is formed; after the product is formed, the fixed seat 3 will continue to move a certain distance relative to the frame 5, and the push rod 202 will not be pushed away by the formed product due to the obstruction of the stop bar 205; therefore, the push rod 202 moves relative to the fixed seat 3 to push the formed product out of the forming assembly 1. In this structure, by setting the push rod 202 and the stop bar 205, the formed product can be removed during the process of the fixed seat 3 moving back and forth and switching the feed port. The entire removal mechanism has a simple structure and does not require a separate removal power device, which reduces the removal cost.

[0064] As a preferred embodiment of the present invention, the straight rod 201 is a threaded rod; the first sliding sleeve 204 is slidably connected to the outside of the threaded rod; second nuts 203 are provided on both sides of the first sliding sleeve 204; the two second nuts 203 are respectively pressed against the two sides of the first sliding sleeve 204. A guide groove is provided on the threaded rod, and the protrusions provided on the first sliding sleeve 204 extend into the guide groove to prevent the first sliding sleeve 204 from rotating on the threaded rod, thereby ensuring the verticality of the push rod 202; the maximum stroke position of the first sliding sleeve 204 and the push rod 202 can be adjusted by loosening or tightening the second nuts 203, thereby ensuring that the product on the molding assembly 1 can be pushed out at a low speed, thereby preventing the molded product from flying toward the bending mechanism at a high speed under the action of the push rod 202.

[0065] As a preferred embodiment of the present invention, a first retaining ring 103a is provided on the movable forming rod 103; a second retaining ring 104a is provided on the fixed forming rod 104; in the feeding state of the metal sheet, the pushing rod 202 is reset. Although the pushing rod 202 will flip when it contacts the metal sheet, after the pushing rod 202 is tilted, its own gravity presses on the cut metal sheet, so that the metal sheet is neatly attached to the first retaining ring 103a and the second retaining ring 104a. The first retaining ring 103a and the second retaining ring 104a are used to position the metal sheet to improve the flatness of the formed product.

[0066] As a preferred embodiment of the present invention, the number of the card slots 302 a is two; the card slots 302 a are evenly distributed on the circular hole 302 .

[0067] In summary, the beneficial effects of the present invention are:

[0068] 1. By changing the installation direction of a bending component of the sheet metal processing and bending equipment, the shape of the formed product can be switched and the bending section can be adjusted; that is, the same sheet metal processing and bending equipment can form a variety of bent products, increasing the types of products formed by the same equipment, improving equipment utilization, and reducing the investment cost of equipment and molds;

[0069] 2. When changing the shape of sheet metal processing and bending equipment, only one of the forming components needs to be replaced, which greatly reduces the labor intensity of changing the shape and makes changing the shape more convenient;

[0070] 3. Adjust the position of the first connecting plate by turning the adjusting bolt so that the movable forming rod and the fixed forming rod are on the same vertical line, so as to align the two positioning grooves, prevent material jamming, and ensure smooth feeding;

[0071] 4. By moving the fixed seat, the two bending mechanisms of the same equipment can be alternately fed and bent, which can reduce the time interval for feeding metal sheets and improve the forming efficiency.

[0072] 5. Through the setting of the push rod and the baffle, the molded product can be removed during the forward and backward movement of the fixed seat and the switching of the feed port. The entire removal mechanism has a simple structure and does not require a separate removal power device, which reduces the removal cost;

[0073] 6. Adjust the maximum stroke position of the sliding sleeve and the push rod through the loose nut to ensure that the product on the forming assembly can be pushed out at a low speed to prevent the formed product from flying toward the bending mechanism at high speed under the action of the push rod, thereby damaging the product and the bending mechanism.

[0074] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
