Description

TECHNICAL FIELD

[0001] The utility model belongs to bar punch press feeding technical field especially, it relates to a bar punch press automatic feeding device. BACKGROUND

[0002] The bar is a kind of steel bar with circular longitudinal section shape and certain length. After being processed by processing equipment, the bar can be processed into e-shaped elastic strip for installation on the track, which is used as installation connecting piece on the track.

[0003] In the processing process, the bar with large length is fed to the processing equipment such as punch press forming, and then is processed into e-shaped elastic strip through subsequent processing.

[0004] During feeding to the punch press forming process, since the bar has large length, it is difficult to push the bar with large length, and the operator needs to continuously push the bar. Secondly, during the punching process, the punch of the punch press presses the end of the bar, and under the action of great impact force, the end of the bar is pressed, and the bar is easily "lifted up", which leads to low safety of punching process. Specifically, during the punching process, it is difficult to lock the bar with large length.

[0005] At the same time, the bar has large length, and during feeding, the bar is heavy, and the hollow part in the length direction of the bar is too large. Since the bar is elastic steel rod material, it has large deflection, which leads to deformation of the bar during feeding, and seriously affects the qualified rate of subsequent processing of the bar into elastic strip.

[0006] Therefore, based on the above-mentioned defects of the bar with large length and large deflection, the efficiency and effect of bar production and processing are not high. INVENTION CONTENTS

In this process, because the bars 4 are supported in multiple sections, the defect that the bars 4 are easily deformed due to the deflection of the long bars 4 is solved.

[0076] Specifically, the locking structure 23 comprises a clamping frame 231, a bar guide pipe 2311 is communicated on the side wall of the clamping frame 231 towards the bar 4 (the outer end portion of the bar guide pipe 2311 is large, the inner end portion is small, and the bar guide pipe 2311 is trumpet-shaped, so as to facilitate the introduction of the bar), clamping cylinders 232 are installed at the two sides of the clamping frame 231, clamping seats 233 located in the clamping frame 231 are fixedly connected on the piston rods of the clamping cylinders 232 (the piston rods of the clamping cylinders 232 are slidingly connected with the clamping frame 231), and an arc-shaped notch for clamping the bar 4 is formed in the clamping seat 233.

[0077] When the bar 4 is guided into the clamping frame 231 along the bar guide pipe, at this time, under the cooperation of the clamping cylinders 232 on both sides, the driving clamping seat 233 clamps the bar 4 between the arc-shaped notches. Under the cooperation of the front and rear locking structures 23, the part of the bar 4 close to the stamping position is fully locked, so as to greatly improve the stability of the bar 4 during stamping.
