[0001] This invention relates to the field of metal bending equipment, and more particularly to a metal sheet bending and feeding device. Background Technology

[0002] Metal sheets are raw materials used in metal manufacturing processes. Products are formed by processing metal sheets.

[0003] Bending technology is an essential process in the processing of metal sheets. Bending technology can reduce welding and cutting operations, thereby further improving the integrity and aesthetics of the product.

[0004] In traditional bending technology, the bending angle is determined by the depth of the punch entering the die, which is suitable for small and medium batch production, can reduce metal surface damage, and requires less tonnage force. However, it is prone to springback effect, which can cause the metal to spring back after bending, affecting subsequent processing. Summary of the Invention

[0007] A heat-conducting plate is provided on the side of the heating plate facing the limiting plate; a heating component is provided inside the heating plate and the heating component is connected to the heat-conducting plate; a control unit is provided on the side of the heating plate away from the limiting plate.

[0008] The lower end of the force-bearing rod is fixed to the movable seat; a plurality of slots are provided on the upper part of the movable seat, and the plurality of slots are arranged sequentially along the movable seat; a sliding groove is provided on the lower part of the movable seat on opposite sides; at least two sliding blocks are provided at the lower end of the clamping rod, and the two sliding blocks are respectively embedded in a corresponding sliding groove, and the two sliding blocks reciprocate along the extension direction of the two opposite sliding grooves; a solenoid valve is provided in the lower end of the clamping rod, and a protrusion is provided at the lower end of the solenoid valve, and the solenoid valve is embedded in one of the plurality of slots by the protrusion; a rotating motor is provided between the movable seat and the rotating seat, and the movable seat swings in one direction along the axis by the rotating motor.

[0009] The clamping rod has at least two fasteners at its top end; the force-bearing rod has a guide base at its top end, and a gear motor is installed inside the guide base; a through slot is opened in each of the two fasteners and the guide base, and the gear of the gear motor in the guide base faces into the through slot; a guide plate runs through the through slots of the two fasteners and the guide base; the clamping rod reciprocates in one direction along the extension direction of the guide plate.

[0010] A guide belt is provided between the two bases, the guide belt is connected end to end, and a plurality of guide wheels are wound inside the guide belt. The plurality of guide wheels are arranged sequentially along the extension direction of the bases. The plurality of guide wheels are each embedded in the two bases by a shaft, and each guide wheel rotates along the axis of the shaft. A shaft motor is connected to the shaft of one of the guide wheels, and the shaft motor is embedded inside one of the two bases. The outward surface of the guide belt is recessed inward.

[0011] Each of the two bases has at least two supporting legs on one side of its orientation. One of the bases connected to the limiting plate has an extension plate at one edge of its orientation. The extension plate has a vertical plate on each of its front and rear opposite sides. Each vertical plate has several through holes, and several embedded posts are embedded in the through holes. One end of each embedded post is fixed to a pull block. On one side of the limiting plate that is in contact with the vertical plate, there is an embedding groove.

[0015] This invention guides the metal sheet vertically to the bending area and then bends it. It employs a multi-angle rotating clamping assembly structure (a combination of a force-bearing rod and a clamping rod). As the metal sheet is introduced into the heating plate and limiting plate, the heating plate softens it, making it easier to bend. The softened metal sheet is guided by a guide belt to the gap between the force-bearing rod and the clamping rod, where it is clamped. Then, a rotating seat below rotates the force-bearing rod and the clamping rod in one direction, causing the metal sheet to bend. The rear heating plate and limiting plate provide clamping force during bending, allowing the force-bearing rod and clamping rod to bend. During the heating process, a heat dissipation device dissipates heat from between the heating plate and the limiting plate, preventing heat accumulation that could soften and deform the metal sheet.

[0027] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0028] like Figures 1 to 11As shown, a metal sheet bending and feeding device includes: a heating plate 1, a limiting plate 2, a force-bearing rod 3, a clamping rod 4, a base 5, a guide belt 6, a rotating seat 7, and a heat dissipation device 8. The heating plate 1 and the limiting plate 2 are vertically arranged and opposite to each other. A force-bearing rod 3 and a clamping rod 4 are provided on one side of the heating plate 1 and the limiting plate 2. At least two bases 5 are provided and are respectively fixed below the heating plate 1 and the limiting plate 2. A guide belt 6 is provided between the two bases 5, and the guide belt 6 reciprocates in one direction. At one end, and in the direction guided by the guide belt 6, a rotating seat 7 is provided, and a movable seat 71 is provided above the rotating seat 7. The force-bearing rod 3 and the clamping rod 4 are respectively provided above the movable seat 71. The heat dissipation device 8 is provided above the heating plate 1 and the limiting plate 2, and one end of the heat dissipation device 8 is connected to the fixed seat 81. The fixed seat 81 is fixed to the side of the heating plate 1 away from the limiting plate 2. The other end of the heat dissipation device 8 is connected to a support frame 82, and one end of the heat dissipation device 8 is embedded in a slot opened in the support frame 82.

[0029] This invention guides the metal sheet vertically to the bending area and then bends it. It employs a multi-angle rotating clamping assembly (a combination of the force-bearing rod 3 and the clamping rod 4). As the metal sheet is introduced into the heating plate 1 and the limiting plate 2, the heating plate 1 heats and softens the metal sheet, making it easier to bend and form. The softened metal sheet then passes through the guide belt 6 below into the gap between the force-bearing rod 3 and the clamping rod 4. The metal plate is clamped between the force-bearing rod 3 and the clamping rod 4. Then, the force-bearing rod 3 and the clamping rod 4 are rotated in one direction by the lower rotating seat 7, so that the metal plate is bent under force. The rear heating plate 1 and the limiting plate 2 can provide clamping force for the metal plate during the bending process, and make the rear force-bearing rod 3 and the clamping rod 4 bend. During the heating process of this invention, the heat dissipation device 8 can dissipate the heat emitted between the heating plate 1 and the limiting plate 2 to the outside, so as to avoid the accumulation of heat and the softening and deformation of the metal plate.

[0030] The heating plate 1 has a heat-conducting plate 11 on one side facing the limiting plate 2; a heating component is provided inside the heating plate 1 and the heating component is connected to the heat-conducting plate 11; a control unit 10 is provided on the side of the heating plate 1 away from the limiting plate 2.

[0031] After adopting the above structure, it should be further explained that the heating component used in the heat-conducting plate 11 is an embedded resistance heating structure. By embedding the resistance wire / resistance strip inside the high-temperature resistant substrate (such as cast aluminum, cast copper, ceramic tube, silicon carbide plate), an integrated structure of "substrate + embedded heating element" is formed. The heated metal is in contact with the substrate or is heated by radiation through the substrate.

[0032] The control unit 10 used in this invention is composed of several circuit boards, and the control unit 10 of this invention is connected to the electrical components of this invention, such as motors, by means of electrical conduits. The control unit 10 also uses electrical conduits to connect to external control devices such as computers.

[0033] The lower end of the force-bearing rod 3 is fixed to the movable seat 71; a plurality of slots 72 are provided on the upper part of the movable seat 71, and the plurality of slots 72 are arranged sequentially along the movable seat 71; a sliding groove 73 is provided on the lower side of the movable seat 71 and on opposite sides; at least two sliding blocks 42 are provided at the lower end of the clamping rod 4, and the two sliding blocks 42 are respectively embedded in a corresponding sliding groove 73, and the two sliding blocks 42 reciprocate along the extension direction of the two opposite sliding grooves 73; a solenoid valve 41 is provided in the lower end of the clamping rod 4, and a protrusion is provided at the lower end of the solenoid valve 41, and the solenoid valve 41 is embedded in one of the plurality of slots 72 by means of the protrusion; a rotating motor 74 is provided between the movable seat 71 and the rotating seat 7, and the movable seat 71 swings in one direction along the axis by means of the rotating motor 74.

[0034] The clamping rod 4 has at least two fasteners 40 at its top end; the force-bearing rod 3 has a guide base 31 at its top end, and a gear motor is installed inside the guide base 31; a through groove is opened in each of the two fasteners 40 and the guide base 31, and the gear of the gear motor in the guide base 31 faces into the through groove; a guide plate 33 runs through the through groove of the two fasteners 40 and the guide base 31; the clamping rod 4 moves back and forth in one direction along the extension direction of the guide plate 33.

[0035] With the above structure, it should be further explained that the force-bearing rod 3 and the clamping rod 4 are driven to rotate by the lower rotating motor 74, so that the upper force-bearing rod 3 and the clamping plate 4 clamp the metal plate, and the rotation of the rotating motor 74 causes the clamped metal plate to be bent.

[0036] In order to make the force-bearing rod 3 and the clamping plate 4 applicable to metal plates of different thicknesses, the clamping plate 4 moves according to the arrangement direction of the slots 72 to adjust the clamping width. The clamping plate 4 pushes out the protrusion through the solenoid valve 41 and inserts the protrusion into one of the slots 72 to achieve fixation.

[0037] A guide belt 6 is provided between the two bases 5, the guide belt 6 is connected end to end, and a plurality of guide wheels 61 are wound inside the guide belt 6. The plurality of guide wheels 61 are arranged sequentially along the extension direction of the base 5. The plurality of guide wheels 61 are each embedded in the two bases 5 by a shaft, and each guide wheel 61 rotates along the axis of the shaft. A shaft rotation motor is connected to the shaft of one of the plurality of guide wheels 61, and the shaft rotation motor is embedded inside one of the two bases 5. The outward surface of the guide belt 6 is recessed inward.

[0038] With the above structure, it should be further explained that the inward indentation of the outward-facing surface of the guide belt 6 can prevent the vertically placed metal plate from sliding outward, and also prevent the metal plate from being subjected to force on one of the heating plate 1 and the limiting plate 2 when it is between the heating plate 1 and the limiting plate 2, which would lead to excessive wear between the heating plate 1 and the limiting plate 2.

[0039] Each of the two bases 5 has at least two supporting legs 9 on one side of its orientation. One of the bases 5 connected to the limiting plate 2 has an extension plate 51 at one edge of its orientation. The extension plate 51 has a vertical plate on each of its front and rear opposite sides. Each vertical plate has several through holes, and several embedded posts are embedded in the through holes. One end of each embedded post is fixed to a pull block 52. The limiting plate 2, which is in contact with the vertical plate, has an embedding groove 21. Several embedding holes run through the embedding groove 21. Several embedded posts connected to the pull block 52 run through the vertical plate and are embedded into the embedding groove 21 and the corresponding embedding holes.

[0040] The heat dissipation device 8 has several air vents 84 on its upper part, and a blower motor 85 is connected to the lower part of each air vent 84. The blower motor 85 is embedded in the heat dissipation device 8. The lower part of the heat dissipation device 8 is provided with a slot, and the exhaust port of the blower motor 85 faces the slot at the lower part of the heat dissipation device 8. Several contact switches 80 are provided at the slot of the heat dissipation device 8. Each contact switch 80 is linearly electrically connected to a blower motor 85. Each control switch 80 extends outward through an electrical conduit and extends to the outside of the heat dissipation device 8, and is linearly electrically connected to the control unit.

[0041] With the above structure, it should be further explained that the control switch 80 is a thermal switch, which is an electronic component or device that automatically controls the on and off of the circuit by sensing temperature changes. Its core function is "temperature-triggered action".

[0042] After being heated to a certain extent, the control switch 80 will start the corresponding exhaust motor 85, thereby allowing the corresponding exhaust motor 85 to work and avoiding excessive power consumption caused by multiple exhaust motors 85 working at the same time.

[0043] The heat dissipation device 8 has a guide groove on each of its left and right opposite sides; the support frame 82 has a guide motor 821 on each of its opposite sides in the groove, and each guide motor 821 has a guide track assembly on one side, which is fitted into the corresponding guide groove. The heat dissipation frame 82 moves back and forth along the groove direction of the support frame 82 through the mutual cooperation of the guide track assemblies on both sides and the guide groove.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
