In this way, when encountering a smaller and shorter material rod, there is a certain degree of uncertainty during its sliding, and it is not convenient to adapt to the stable feeding of the material according to the change of the material.

[0004] Therefore, research and improvement are carried out on the existing structure and deficiencies, and a feeding mechanism for a thread rolling machine for processing British standard bolts is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0022] As Figures 1 - 3 shown, a feeding mechanism for a rolling machine for processing British bolts includes a feeding frame 1 and a conveying mechanism 2. The conveying mechanism 2 for stably feeding is arranged in the middle above the feeding frame 1. The conveying mechanism 2 includes an electric push cylinder 201, a push rod 202, a mounting frame 203, a conveying roller 204, a transmission belt 205, wear-resistant convex lines 206 and a connecting spring 207. The output end of the electric push cylinder 201 is connected with a push rod 202, and a mounting frame 203 is fixed at the bottom of the push rod 202. A conveying roller 204 is arranged in the middle of the mounting frame 203. The middle of the surface of the conveying roller 204 is connected with a transmission belt 205, and wear-resistant convex lines 206 are fixed on the outer surface of the transmission belt 205. The middle of the inner side of the push rod 202 is connected with a connecting spring 207. The mounting frame 203 is elastically connected with the push rod 202 through the connecting spring 207;

[0023] Through the conveying roller 204 and the transmission belt 205, which are driven by a reduction motor, through the electric push cylinder 201 and the push rod 202, the transmission belt 205 can be pressed down to fit on the upper surface of the bolt to be fed. With the cooperation of the wear-resistant convex lines 206, the friction of the transmission belt 205 is increased, and the bolt can be automatically pushed forward when the transmission belt 205 rotates. At the same time, the connecting spring 207 is used to ensure that the pressure is not too large, so as to ensure that the state of the bolt under pressure can be kept stable during feeding. And with the adjustable height of the transmission belt 205, bolts of different sizes and lengths can be fed. At the same time, using the servo-type transmission belt 205 can also make the bolts be fed according to the working conditions, so as to make the mechanism work more stably and flexibly;

[0024] As Figure 1 and Figure 4As shown in the figure, a support mechanism 3 for support and adjustment is provided at the bottom of the material guiding frame 1. The support mechanism 3 includes support feet 301 and mating gears 302. The mating gears 302 are installed below the inner sides of the support feet 301. The support mechanism 3 further includes a turning wheel 303. One end of the mating gear 302 is installed with the turning wheel 303. The support mechanism 3 further includes a lead screw 304. The lead screw 304 is fixed above the mating gear 302. The support mechanism 3 further includes a lifting rod 305. The lifting rod 305 is threadedly connected above the outside of the lead screw 304. By turning the mating gear 302 and the mating gears 302 provided with two sets of vertical bevel gears, the lead screw 304 can be driven to rotate, so that the lifting rod 305 can perform telescopic movement between the support feet 301. With the rotating seat provided between the lifting rod 305 and the material guiding frame 1, the height and slope of the material guiding frame 1 can be adjusted, so as to further ensure the smoothness of material guiding of the mechanism and enable the mechanism to be adjusted and used in different environments.

[0025] Working principle: When using the material guiding mechanism for manufacturing British bolts by thread rolling machine, first, through the conveying roller 204 and the transmission belt 205, which are driven by a reduction motor. Subsequently, through the electric push cylinder 201 and the push rod 202, the transmission belt 205 can be pressed down to fit on the upper surface of the bolt to be guided. Then, with the wear-resistant convex lines 206, the friction of the transmission belt 205 can be increased, and the bolt can be automatically pushed forward when the transmission belt 205 rotates. At the same time, the connecting spring 207 is used to ensure that the pressure is not too large, and with the adjustable height of the transmission belt 205, bolts of different sizes and lengths can be guided. Then, by using the servo-type transmission belt 205, the bolt can also be guided according to the working conditions. At this time, by turning the mating gear 302 and the mating gears 302 provided with two sets of vertical bevel gears, the lead screw 304 can be driven to rotate, so that the lifting rod 305 can perform telescopic movement between the support feet 301. Finally, with the rotating seat provided between the lifting rod 305 and the material guiding frame 1, the height and slope of the material guiding frame 1 can be adjusted.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
