Problems solved by technology

With the development of industrial automation, the specifications of bolts and screws are getting higher and higher, and the length changes more. For long-sized bolts and screws, the cold heading machine using the existing straightening device cannot meet the quality requirements of the product, so the scrap rate Very high, causing great economic losses to the enterprise

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] It can be known from the top view of the straightening device of the prior art cold heading machine shown in FIG. The several rollers 21 described are installed on the horizontal support 13, equidistant and staggered in two rows and distributed on the horizontal support 13 of the cold heading machine. One row of rollers 21 is connected with a screw 22, and the relative position of the other row of rollers 21 is adjusted by manually adjusting the screw 22, that is, the diameter of the blank determines the relative position of the two rows of rollers. When the cold heading machine is working, the billet is fed in from the first roller for straightening in advance, and the bent billet is straightened through the force of the feed wheel that drives the billet forward linearly and several rollers. Since the blank is only subjected ...

Abstract

The invention discloses a cold header aligning device, which comprises a level supporting frame(13), a feeding wheel(5) that drives the blank to go forward linearly; one end of the level supporting frame(13) is fixed with a machine frame girder(12) that is fixed on the machine frame(7); another end is fixed on the feeding mechanism of the cold header. The aligning device also includes a hollow aligning shaft(1), and a transmission mechanism. A supporting frame girder(3) is fixed on the level supporting frame(13); one end of the hollow aligning shaft(1) is rotatably connected with the machine frame girder(12), another end is rotatably connected with the supporting frame girder(3); one end of the hollow aligning shaft(1) that sticks out of the supporting frame girder(3) is connected with the transmission mechanism; the transmission mechanism is connected with the machine frame(7) and both of them are fixed on a level plate(11). The cold header aligning device in this structure has excellent aligning effect, can improve the passing rate of finished products, therefore can improve the economic benefit.

Description

technical field [0001] The invention relates to a straightening device, in particular to a blank straightening device for a cold heading machine used for processing fasteners such as bolts and screws. Background technique [0002] In my country's national standard fastener industry, most manufacturers have adopted high-efficiency automatic cold heading machines to process bolts, screws and other fasteners. Since the blanks for making fasteners are generally coiled, the blanks must be straightened before machining the fasteners. The straightening device of the cold heading machine in the prior art generally adjusts the straightness of the blank through several rollers. The rollers are distributed equidistantly and staggeredly on the horizontal support of the cold heading machine. The coil material starts to be straightened from the first roller, and through the force of the feed wheel and several rollers that drive the billet to move forward linearly, Straighten bent blanks...
