[0002] Generally, the material of metal strip leads is copper or aluminum. Especially, copper strips have the advantages of being hard, not easily corroded, high temperature resistant, high pressure resistant, light in weight, good in heat conductivity, and high in low temperature strength. Metal strips are fire and heat resistant and can still maintain their shape and strength at high temperatures without aging. Copper strips combine many advantages: they have the high strength of general metals; at the same time, they are easier to bend, twist, crack, and break than general metals, and have a certain ability to resist thermal deformation and impact. Metal strips are often used in circuit conduction devices.

[0025] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0026] Referring to Figures 1 to 5 As shown, the present invention provides a metal strip lead bending tool, including a base 1, on which a first bending mechanism and a second bending mechanism are fixedly installed. The first bending mechanism is used to bend the metal strip 31 in the horizontal direction, and the second bending mechanism is used to bend the metal strip 31 that has completed the horizontal bending in the vertical direction;

[0027] The first bending mechanism includes a pressing component and a movable component. The pressing component is fixedly installed at the top of the base 1, and the movable component is hinged at the top of the base 1. The movable component is arranged corresponding to the pressing component;

[0028] The second bending mechanism includes a fixing component, and a second handle 29 is hinged to one side of the fixing component. The second handle 29 is perpendicular to the base 1.

[0029] By setting the pressing component, one end of the metal strip 31 is pressed and fixed. By using the movable component hinged on the base 1 to apply low pressure to the other end of the metal strip 31, and controlling the rotation angle of the movable component, the bending angle of the metal strip 31 is controlled, thereby realizing the horizontal bending of the metal strip 31. By setting the fixing component to fix the bottom end of the metal strip 31 that has completed the horizontal bending, and by pressing down the second handle 29, a shearing force is provided for the other end of the metal strip 31, thereby realizing the vertical bending of the metal strip 31.

[0030] The utility model is easy to operate, and can improve the consistency and processing efficiency of the bending of the metal strip 31.

[0031] Furthermore, the pressing component includes a first mounting plate 2 fixedly installed at the top end of the base 1, a first bracket 3 and a first stopper 9. The first mounting plate 2 and the first stopper 9 are respectively arranged on both sides of the first mounting plate 2, and the first stopper 9 abuts against the first mounting plate 2. A first chute 8 is formed on the first mounting plate 2, and a first pressing block 5 is slidably connected to the first chute 8. An adjusting bolt 4 is threadedly connected to the first bracket 3. One end of the adjusting bolt 4 close to the first stopper 9 is rotatably connected to the first pressing block 5. The metal strip 31 is pressed against the first stopper 9 by the first pressing block 5, and the movable component is correspondingly arranged with the first pressing block 5.

[0032] By rotating the adjusting bolt 4, the adjusting bolt 4 pushes the first pressing block 5 to approach the first stopper 9, and presses one end of the metal strip 31 between the first pressing block 5 and the first stopper 9.

[0033] Furthermore, the movable component includes a limiting cylinder 7 vertically and fixedly connected to the top end of the base 1. One end of a second mounting plate 11 is hinged to the limiting cylinder 7. A second stopper 17 and a second bracket 13 are fixedly installed on both sides of the second mounting plate 11. A second chute 12 is formed on the second mounting plate 11, and a second pressing block 15 is slidably connected to the second chute 12. An adjusting bolt 14 is threadedly connected to the second bracket 13. One end of the adjusting bolt 14 close to the second stopper 17 is rotatably connected to the second pressing block 15. The metal strip 31 is in sliding contact with the second stopper 17 through the second pressing block 15. One end of the second mounting plate 11 far from the limiting cylinder 7 is fixedly connected with a first handle 18.

[0034] By rotating the adjusting bolt 14, the adjusting bolt 14 pushes the second pressing block 15 to approach the second stopper 17, so that the other end of the metal strip 31 is slidably limited between the second pressing block 15 and the second stopper 17. At the same time, by rotating the first handle 18, the movable end of the metal strip 31 deforms under the limitation of the limiting cylinder 7 and driven by the first handle 18, so as to realize horizontal bending.

[0035] Furthermore, in order to improve the pressing stability, a first notch 10 is formed at one end of the first pressing block 5 close to the first stopper 9, and the first notch 10 abuts against the metal strip 31.

[0036] Furthermore, in order to improve the sliding smoothness of the metal strip 31, a second notch 16 is formed at one end of the second pressing block 15 close to the second stopper 17, and the second notch 16 is in sliding contact with the metal strip 31.

[0037] Further, the fixing component includes a first mounting block 19 and a second mounting block 20 fixedly installed in parallel at the top of the base 1. A cushion block 21 is slidably arranged between the first mounting block 19 and the second mounting block 20, and the bottom end of the cushion block 21 is in sliding contact with the top end of the base 1.

The slider 26 is slidably arranged between the first support block 24 and the second support block 25. The slider 26 is located above the cushion block 21. A plurality of pressing bolts 27 are threadedly connected to the slider 26. The bottom ends of the pressing bolts 27 penetrate through the slider 26 and abut against the cushion block 21.

[0038] By rotating the pressing bolt 27, one end of the metal strip 31 after horizontal bending is pressed on the cushion block 21. By rotating the adjusting bolt 23, the slider 26 and the cushion block 21 can be driven to move away from or close to the third support 22, thereby adjusting the distance between the fixed end of the metal strip 31 and the second handle 29, and further realizing the adjustment of the vertical bending angle of the other end of the metal strip 31.

[0039] Further, in order to prevent sudden changes at the bending part of the metal strip 31, a baffle 6 is fixedly connected to the top end of the limiting cylinder 7, and the side of the baffle 6 close to the base 1 is in sliding contact with the metal strip 31.

[0040] The working principle of the metal strip lead bending tool provided by the present utility model is as follows:

[0041] I. The first process of horizontal bending: Rotate the first handle 18 to make the second mounting plate 11 and the first mounting plate 2 in a straight line. Press one end of the metal strip 31 between the first pressing block 5 and the first stop block 9. The other end of the metal strip 31 passes through the limiting groove formed by the notch 16 on the second pressing block 15 and the second stop block 17. Rotate the first handle 18. As the angle of the first handle 18 changes, the movable end of the metal strip 31 slides in the limiting groove, thereby realizing the horizontal bending of the metal strip 31. In order to reduce the resistance, lubricating grease can be applied in the limiting groove.

[0042] II. Second process: vertical bending: Fix one end of the metal strip 31 that has completed horizontal bending between the pressing bolt 27 and the cushion block 21. By rotating the adjusting bolt III 23, adjust the distance between the fixed end of the straight metal strip 31 and the handle II 29. Press down the handle II 29 to provide a shearing force for the movable end of the metal strip 31 by the handle II 29, thereby realizing the vertical bending of the metal strip 31. By controlling the rotation angle of the handle II 29, control the bending angle of the metal strip 31, and finally complete the bending process of the metal strip 31.
