Description

Stock stop of pipe blank cutting and cutting machine

Technical Field

The utility model relates to a mechanism, especially a pipe blank cutting stock cutter stock stop.

Background

The stock cutter is the machine that needs the equal parts cutting material to process such as steel pipe, stock cutter on the market utilizes the striker plate to keep off the material and the equal parts cutting, this kind of mode is because the striker plate is strikeed by the material for a long time, thereby can cause the striker plate to warp more and more greatly and sound also very much, thereby can cause the material cutting length of each batch to have slight difference, cause follow-up man-hour to the material, cause the precision, size puzzlement, be unfavorable for the long-term stable excision processing of material.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve above-mentioned prior art's shortcoming, provide one kind can be long-term high-efficient, stable to the material block the pipe blank stock stop of equal portion cutting, satisfied the long-time equidistant, of the material that the user used the stock cutter also can guarantee to cut off demand of high quality.

The utility model provides a technical scheme that its technical problem adopted: the stock stop mechanism of the pipe blank cutting and cutting machine comprises a base, wherein a support frame is fixed on the base, a pair of guide rails which are oppositely arranged is installed at the bottom of the support frame, slide blocks are connected on the two guide rails in a sliding manner, a support plate which is fixed on the two slide blocks is arranged below the two guide rails, a mounting frame is fixed at the bottom end of the support plate, a first transverse hole, a second transverse hole and a third transverse hole are formed in the mounting frame, the section of the third transverse hole is larger than that of the first transverse hole but smaller than that of the second transverse hole, a top rod with a tip end is inserted in the first transverse hole, an insertion block which is inserted in the second transverse hole is fixed on the top rod, a compression spring is installed at the second transverse hole, an air cylinder is fixed on the support frame, a threaded rod is fixed at the outer end of a piston rod of the air cylinder, a support pier is fixed on the top surface of the support plate, a threaded sleeve which is in threaded fit with the threaded rod is fixed at the top end of the support pier, and the threaded sleeve is arranged in the threaded sleeve, and the outer two sides are in threaded connection with compression nuts which are compressed at the threaded sleeves. The supporting frame, the guide rail, the sliding block, the supporting plate and the mounting frame have the functions that the mounting frame can stably move and operate at the supporting frame; the first transverse hole, the second transverse hole, the third transverse hole, the ejector rod and the compression spring have the effects that the tube blank can be flexibly blocked, the buffering effect can be achieved, and the blocking fatigue condition is further avoided; the effect of cylinder, threaded rod, buttress, threaded sleeve pipe, gland nut here is, can drive the ejector pin and carry out isometric the stopping to the pipe billet to appointed position, and two gland nuts here can adjust the position of mounting bracket to the adaptation is to the cutting of the different length equal divisions of pipe billet.

Further perfection, and the end face of the second transverse hole is fixed with a ring-shaped blocking convex block with a circular arc-shaped section. The ring-shaped blocking convex block has the effect that the insert block is in line contact with the ring-shaped blocking convex block when being driven, so that the insert block is more stable when being operated to contact the tail end.

Further perfection, and a vent hole is arranged between the third cross hole and the surface of the mounting frame. The vent hole has the effects that the insert block can move more smoothly at the third transverse hole, and the condition that the insert block moves unsmoothly left and right due to the pressure intensity of air pressure is avoided.

The utility model discloses profitable effect is: the utility model has the advantages of ingenious and reasonable structural design, utilize the carriage, the guide rail, the slider, the backup pad, the mounting bracket can make the mounting bracket can steadily move the operation in the carriage department, utilize first cross bore, the second cross bore, the third cross bore, the ejector pin, compression spring can carry out the flexibility and block to the pipe blank, can play the cushioning effect, and then avoid taking place and block the tired condition, utilize the cylinder, the threaded rod, the buttress, the thread bush, gland nut can drive the ejector pin to the assigned position and carry out isometric block to the pipe blank, utilize two gland nuts can adjust the position of mounting bracket, thereby adapt to the cutting to the equal parts of different length of pipe blank, when utilizing the ejector pin to block the material, compression spring can make the ejector pin move a small segment distance, thereby release kinetic energy, then blocked again, so as to make the ejector pin indeformable for a long term, thereby ensure that the material of every section of cutting is equidistant, ensures the quality of subsequent processing of the material and is worth popularizing and applying.
