Description

Technical Field

[0001] The utility model relates to the technical field of wire processing, in particular to a straightening device. Background Art

[0002] The wires used in the electric control cabinet are copper wires with a rated diameter. When these copper wires are connected, they are first straightened by straightening, and then the outer skins at both ends of the wires are stripped. At present, when straightening the wires, one end of the wire is clamped by a bench vise, and then the other end of the wire is clamped by a hand vise. After clamping, the wire is straightened by stretching. This operation method is relatively simple, but the efficiency is low. There is also a method of multi-wheel group straightening. This method is prone to damage the outer skin during the straightening process, thus causing safety accidents. Summary of the Utility Model

A plurality of positioning grooves are respectively formed at the upper end of the lower clamping seat 2 and the lower end of the upper clamping block 27. Vertical rods 20 are respectively provided at both ends of the lower clamping seat 2. A spring 26 is provided between the lower clamping seat 2 and the upper clamping block 27. The spring 26 is sleeved on the vertical rods 20. At the upper ends of the vertical rods 20, an L-shaped seat 21 is installed. A middle block 22 is rotatably provided between the L-shaped seats 21. The vertical rods 20 pass through the upper clamping block 27. A concave member 23 is provided on the middle block 22. The lower end of the concave member 23 is in an arc structure. An adjusting screw rod 25 is provided on the transverse section of the concave member 23. A rotating handle rod 24 is provided at the upper end of the adjusting screw rod 25. The lower end of the concave member 23 acts on the upper end of the upper clamping block 27.

[0020] A hydraulic cylinder 3 is installed on the lower wall of the long strip base plate 1. A movable head 30 is provided at the movable end of the hydraulic cylinder 3. A movable rod 32 is movably provided in the movable hole 10. A lower cushion block 37 is sleeved on the movable rod 32. The lower cushion block 37 is located on the upper side of the long strip base plate 1. A pressing block 38 is installed at the upper end of the movable rod 32. Grooves are respectively formed at the lower end of the pressing block 38 and the upper end of the lower cushion block 37. A lug 33 is provided at the lower end of the movable rod 32. A concave seat 34 is provided at the inner end of the lug 33. A lower top groove 35 is formed at the outer end of the concave seat 34.
