[0004] The bending blade of the above bending machine is supported and fixed only by bolts, the stability of the bending blade is low, and it is laborious to use bolts for positioning, installation and disassembly. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a bending machine and a tool replacement system that are easy to replace tools, which have the advantages of being able to improve the stability of the bending blade and facilitating the installation and disassembly of the bending blade. It solves the problem that the bending blade of the existing bending machine is only supported and fixed by bolts, the stability of the bending blade is low, and it is more laborious to use bolts for positioning, installation and disassembly.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a bending machine and a tool replacement system thereof that are convenient for tool replacement, comprising a fixed base plate, a bending blade is provided at the bottom of the fixed base plate, the upper surface of the bending blade is fixedly connected to a T-shaped mounting plate, a T-shaped groove is provided inside the fixed base plate, the outer surface of the T-shaped mounting plate is slidably connected to the fixed base plate through the T-shaped groove, the interior of the fixed base plate is rotatably plugged with equidistantly arranged screw rods, the outer circumferential surface of each screw rod is threadedly connected to a positioning rod, the interior of the T-shaped mounting plate is provided with equidistantly arranged positioning holes, the outer circumferential surfaces of the positioning rods are slidably plugged with the bending blades through the positioning holes, and the outer circumferential surface of each screw rod is fixedly sleeved with a handwheel.

[0007] Through the above scheme, since the bending blade of the existing bending machine is only supported and fixed by bolts, the stability of the bending blade is low, and it is more laborious to use bolts for positioning, installation and disassembly. By providing a T-shaped mounting plate and a T-shaped slide groove, the support effect of the bending blade is effectively improved, and the stability of the bending blade is improved. By rotating the screw rod to drive the positioning rod to move in or out of the positioning hole, it is convenient to position and release the positioning of the T-shaped mounting plate, thereby facilitating the installation and disassembly of the bending blade.

[0008] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each screw rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the fixed base plate.

[0009] Through the above scheme, the screw rod is restricted to avoid sliding and deflection of the screw rod, thereby increasing the stability of the screw rod movement.

[0010] Furthermore, the outer circumferential surface of each positioning rod is fixedly connected to two limit blocks, and the outer surface of each limit block is slidably connected to the fixed base plate through a hollow groove provided inside the fixed base plate.

[0011] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the lead screw, so that the positioning rod is always moved laterally.

[0012] Furthermore, each hand wheel has an insertion rod slidably inserted inside, the outer circumference of the insertion rod is fixedly sleeved with a magnet ring, the interior of the fixed base plate is fixedly connected with equidistantly arranged sleeves, and the outer circumference of the magnet ring is slidably connected to the inner wall of the sleeve.

[0013] Through the above scheme, the hand wheel is restricted by the insertion rod, the magnet ring and the sleeve to prevent the hand wheel from rotating, thereby preventing the screw rod from rotating, and improving the stability of the positioning of the T-shaped mounting plate.

[0014] Furthermore, a collar is fixedly sleeved on the outer circumferential surface of each of the insertion rods, a spring is fixedly connected to one side of the collar close to the hand wheel, and the other end of the spring is fixedly connected to the outer surface of the hand wheel.

[0015] Through the above solution, the magnet ring is restricted by the elastic force of the spring itself, so as to prevent the magnet ring from falling off from the inside of the sleeve easily.

[0016] Furthermore, the inner wall of each sleeve is fixedly connected with a first magnet sheet.

[0017] Through the above solution, the magnet ring is restricted by the magnetic attraction between the magnet ring and the first magnet sheet, so as to prevent the insertion rod from moving back easily.

[0018] Furthermore, a second magnet sheet is fixedly connected to the interior of each of the hand wheels, and an inner wall of the second magnet sheet is slidably connected to the outer circumferential surface of the insertion rod.

[0019] With the above solution, when the hand wheel needs to be rotated, the rod can be pulled to drive the magnet ring out of the sleeve and make the magnet ring magnetically attracted to the second magnet sheet, so as to prevent the rod from automatically moving back under the action of the spring and affecting the rotation of the hand wheel.

[0020] Furthermore, an auxiliary plate is fixedly connected to the upper surface of the T-shaped mounting plate, and the right side surface of the auxiliary plate is in contact with the left side surface of the fixed base plate.

[0021] Through the above scheme, the auxiliary plate can be used to assist the T-shaped mounting plate in installation. When the auxiliary plate contacts the fixed base plate, the positions of the positioning rod and the positioning hole correspond to each other, which facilitates the installation of the bending blade.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The bending machine and tool replacement system thereof which are convenient for tool replacement effectively improve the supporting effect of the bending blade and enhance the stability of the bending blade by arranging the T-shaped mounting plate and the T-shaped sliding groove, and drive the positioning rod to move into or out of the positioning hole by rotating the screw rod, so as to facilitate positioning and releasing the positioning of the T-shaped mounting plate, and further facilitate installation and removal of the bending blade, thus solving the problem that the bending blade of the existing bending machine is only supported and fixed by bolts, has low stability, and is laborious when positioning, installing and removing by bolts.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 3 and Figure 4 The outer circumference of each screw rod 5 is fixedly sleeved with a limit ring 8, and the outer circumference of the limit ring 8 is rotatably connected to the inside of the fixed base plate 1 to limit the screw rod 5, prevent the screw rod 5 from sliding and deviating, and increase the stability of the movement of the screw rod 5.

[0033] See also Figure 3 and Figure 4 The outer circumferential surface of each positioning rod 6 is fixedly connected to two limit blocks 9, and the outer surface of each limit block 9 is slidably connected to the fixed base plate 1 through an empty groove opened inside the fixed base plate 1, thereby restricting the positioning rod 6, preventing the positioning rod 6 from rotating with the screw rod 5, and prompting the positioning rod 6 to always move laterally.

[0034] See also Figure 1 , Figure 3 and Figure 4 A plug rod 11 is slidably inserted inside each hand wheel 10, and a magnet ring 12 is fixedly sleeved on the outer circumference of the plug rod 11. The interior of the fixed base plate 1 is fixedly connected with equidistantly arranged sleeves 13, and the outer circumference of the magnet ring 12 is slidably connected to the inner wall of the sleeve 13 respectively. The hand wheel 10 is restricted by the plug rod 11, the magnet ring 12 and the sleeve 13 to prevent the hand wheel 10 from rotating, thereby preventing the screw rod 5 from rotating, and improving the stability of the positioning of the T-shaped mounting plate 3.

[0035] See also Figure 1 , Figure 3 and Figure 4 The outer circumferential surface of each insertion rod 11 is fixedly sleeved with a ring 14, and the side of the ring 14 close to the handwheel 10 is fixedly connected with a spring 15, and the other end of the spring 15 is fixedly connected to the outer surface of the handwheel 10. The elastic force of the spring 15 itself restricts the magnet ring 12 to prevent the magnet ring 12 from easily falling off from the inside of the sleeve 13.

[0036] See also Figure 3 and Figure 4 The inner wall of each sleeve 13 is fixedly connected with a first magnet sheet 16, and the magnet ring 12 is restricted by the magnetic attraction between the magnet ring 12 and the first magnet sheet 16 to prevent the insertion rod 11 from moving back easily.

[0037] See also Figure 3 and Figure 4 A second magnet sheet 17 is fixedly connected to the interior of each hand wheel 10, and the inner wall of the second magnet sheet 17 is slidably connected to the outer circumferential surface of the insertion rod 11. When the hand wheel 10 needs to be rotated, the insertion rod 11 can be pulled to drive the magnet ring 12 to move out of the sleeve 13, and the magnet ring 12 is magnetically attracted to the second magnet sheet 17, so as to prevent the insertion rod 11 from automatically moving back under the action of the spring 15 and affecting the rotation of the hand wheel 10.

The right side of the auxiliary plate 18 contacts the left side of the fixed base plate 1. The auxiliary plate 18 can be used to assist the T-shaped mounting plate 3 in installation. When the auxiliary plate 18 contacts the fixed base plate 1, the positions of the positioning rod 6 and the positioning hole 7 correspond to each other, which facilitates the installation of the bending blade 2.

[0039] The present embodiment provides a bending machine and a tool changing system thereof which are convenient for tool replacement. By setting a T-shaped mounting plate 3 and a T-shaped slide groove 4, the supporting effect of the bending blade 2 is effectively improved, and the stability of the bending blade 2 is improved. By rotating the screw rod 5 to drive the positioning rod 6 to move into or out of the positioning hole 7, the T-shaped mounting plate 3 can be positioned and released, and the bending blade 2 can be installed and disassembled. This solves the problem that the bending blade 2 of the existing bending machine is only supported and fixed by bolts, has low stability, and is laborious to position, install and disassemble using bolts.

[0040] It should be noted that the insertion rod 11 is made of non-magnetic hard metal material and will not generate magnetic attraction with the second magnet sheet 17 .

[0041] The working principle of the above embodiment is:

[0042] The upper surface of the fixed base plate 1 is fixedly connected to the lifting device of the external bending machine, and the T-shaped mounting plate 3 can only slide inside the T-shaped slide groove 4, which effectively improves the supporting effect of the bending blade 2. When the bending blade 2 needs to be installed, the right end of the T-shaped mounting plate 3 is inserted from the left side of the T-shaped slide groove 4, and the T-shaped mounting plate 3 is installed until the auxiliary plate 18 contacts the fixed base plate 1, and then the hand wheel 10 is rotated in turn to drive the screw rod 5 to rotate, and the screw rod 5 drives the positioning rod 6 to move, prompting the positioning rod 6 to be inserted into the positioning hole 7 to complete the positioning operation of the T-shaped mounting plate 3, and the hand wheel 1 Before rotating, pull the plunger 11 to drive the magnet ring 12 to move outward, so that the magnet ring 12 is adsorbed on the second magnet sheet 17 to prevent the plunger 11 from hindering the rotation of the hand wheel 10. After the positioning is completed, push the plunger 11 to move, so that the magnet ring 12 is inserted into the sleeve 13 and adsorbed with the first magnet sheet 16. The plunger 11 is restricted by the first magnet sheet 16 and the spring 15 to prevent the magnet ring 12 from easily falling off from the inside of the sleeve 13, thereby restricting the hand wheel 10 and preventing the hand wheel 10 and the screw rod 5 from rotating, thereby improving the stability of the positioning of the T-shaped mounting plate 3.
