Embodiment 1

[0079] This embodiment provides a production method for forming elastic strips, which includes the stamping and forming steps of the material bar successively by the first-order press, the second-order press and the third-order press, and also includes

[0080] Step A: The material rod is automatically loaded and heated, and the heated material rod is positioned;

[0081] Step B: Detect the temperature of the material rod after positioning in step A, and judge whether the temperature of the material rod is qualified. The qualified temperature range is 950 to 1000 ° C. Take out and recycle the unqualified product, and take out the qualified product and put it into the first-order press middle;

[0082] Step C: Take out the material rod stamped by the first-order press and place it on the first-order turntable;

[0083] Step D: Take off the material rod on the turntable of the first sequence, and put it into the second sequence press;

[0084] Step E: Take out the stamped mate...

Embodiment 2

[0091] Such as Figure 1 to Figure 5 As shown, this embodiment provides an automatic feeding and heating device for spring bars, which includes a frame and a heating furnace body 14, and an automatic feeding mechanism and a feeding mechanism are arranged on the frame.

[0092] The automatic feeding mechanism includes a feeding machine, a lifting cylinder 1005, a plurality of lifting plates 1004, and a plurality of fixing plates 1021. One end of the feeding machine is a space for placing rods and is inclined toward the direction of the heating furnace body 1014. The other end of the feeder is provided with a lifting cylinder 1005, a lifting plate 1004 and a fixed plate 1021. The lifting cylinder 1005 is fixedly connected to a plurality of lifting plates 1004, and the heights of the upper ends of a plurality of lifting plates 1004 are raised successively. The upper end of the plate 1021 is inclined downward toward the heating furnace body 1014, and a plurality of fixed plates 10...

Embodiment 3

[0103] Such as Figure 6 ~ Figure 8 As shown, this embodiment provides a sequence of transfer tooling 6, including a carrier frame 601, a fixed frame 604 and a first laser distance measuring sensor 602, the middle part of the carrier frame 601 is provided with the fixed frame 604, and the fixed frame 604 is provided with a groove for placing material rods, the first laser distance measuring sensors 602 are arranged on both sides of the carrier frame 601 , and the two first laser distance measuring sensors 602 are arranged symmetrically around the fixing frame 604 . In the production of elastic bars, this tooling is set after the first-order press 5 and before the second-order press 8, as the first-order detection and transfer tooling of the material bar, and the material bar after the first-order press is placed on the fixed frame 604 Above, the symmetry of the material rod is checked by the first laser ranging sensors 602 on the left and right sides. If the symmetry of the ma...

Abstract

The invention relates to a production method for forming elastic strips, which comprises the stamping and forming steps of a material rod successively by a first-order press, a second-order press and a third-order press, and also includes automatic feeding and heating of the material rod, and the heating of the heated material rod Carry out positioning; detect the temperature of the material rod after positioning, and judge whether the temperature of the material rod is qualified, and take out the qualified product and put it into the first-order press; take out the material rod after being stamped by the first-order press, and place it on the first-order turntable on; remove the material rod on the first sequence turntable, and put it into the second sequence press; take out the material rod after the second sequence press punches, and place it on the second sequence turntable; put the second sequence on the second sequence turntable The material rod is removed and put into the three-sequence press; the temperature of the material rod on the three-sequence press is tested, and if the temperature is qualified, it is taken out and sent to the quenching tank. A spring forming production system is also provided. The invention reduces the moving path of the material each time, accelerates the production cycle speed and is more stable, and has high material transmission efficiency and high safety factor.

Description

technical field [0001] The invention relates to the field of elastic strip forming production, in particular to a elastic strip forming production method and system. Background technique [0002] Under the general trend of rapid development of high-speed railways and urban rail subways in my country, Type I and Type II spring clips, which are widely used on seamless railway tracks with 60 kilograms per meter of steel rail, have raised new standards in terms of production capacity, quality, production process control, etc. Higher requirements. At present, most domestic enterprises adopt traditional manual production methods. Under the conditions of workpiece temperature of 1000 ℃ and ambient temperature of nearly 40 ℃, there are problems such as unstable quality, low safety factor and high labor cost. [0003] At present, the conventional automatic production line system of clips at home and abroad is centered on three presses, and each press is equipped with a robot. This typ...
