Detailed Description
As shown in fig. 1, a straightening device for a nickel-iron alloy wire rod comprises a paying-off mechanism 1, a first wire throwing mechanism 2 and a second wire throwing mechanism 3.
As shown in fig. 1 to 3, the payout mechanism 1 includes a payout reel 4, a first reel 5, a tension reel 6, and a second reel 7. Wherein, the paying-off reel 4 is connected with a paying-off motor 23 through a first belt transmission mechanism 8; the pay-off reel 4, the first belt conveying mechanism 8, the pay-off motor 23 and the like are all installed on an installation seat at the lowest part of the case, the Dumet wire coil is placed on the pay-off reel 4, and the pay-off reel 4 is driven to rotate through the pay-off motor 23 to achieve pay-off. The first reel 5 and the tension reel 6 are respectively arranged on the left and right of the mounting seat above the machine case in pairs, wherein the tension reel 6 is mounted on a tension mounting seat 9, and the tension mounting seat 9 is arranged on a first sliding frame 10 in a sliding mode and can freely slide up and down along the first sliding frame 10. Under normal conditions, the tensioning mounting seats 3-9 are kept immovable by upward pulling force of two ends of the Dumet wires, and when the Dumet wires are stretched too tightly or too loosely in the subsequent forward straightening and conveying process, the tensioning mounting seats 3-9 move upwards or downwards for adjustment.
The rightmost end of the mounting seat above the case is provided with a second reel 7, and the second reel 7 is opposite to the first line throwing mechanism 2. The wire 13 is horizontal N-shaped and can enter the first wire throwing mechanism 2 after passing through the wire releasing mechanism 1. Here, due to the tension reel 6, the tension reel 6 ensures that the output line is always in a preliminary tension-straightened state during the paying-off process.
In addition, in order to control the tensioning force, a balancing weight can be arranged on the tensioning mounting seat 9.
As shown in fig. 4-5, the first wire throwing mechanism 2 includes a first group of guide rollers 11 and a second group of guide rollers 12, the first group of guide rollers 11 and the second group of guide rollers 12 are all a plurality of staggered rollers 20, and grooves are distributed on the rollers 20, and the grooves can guide the wires 13.
