A head-making equipment for copper tube drawing machine

Abstract

The invention discloses head-making equipment for a copper pipe drawing machine. The equipment comprises a frame body, a worktable and a mounting frame, and also comprises a head-making device and a feeding device, wherein the head-making device comprises a first rotary sleeve, a first gap, a first head-making roller, a mounting table, a second head-making roller and a driving mechanism; the feeding device comprises a feeding roller, a second rotary sleeve, a second gap, a power mechanism and a moving mechanism. The equipment has the following advantages and effects that by utilizing the moving mechanism, the position on which the first head-making roller is located is changed, so that the first made head roller can be positioned under the second head-making roller or the feeding roller, so that head-making and feeding functions are realized, the feeding of the copper pipe is convenient, the head is renewedly made after the head-making part is fractured, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to copper pipe production equipment, in particular to a head-making equipment used for a copper pipe drawing machine. Background technique [0002] The copper tube drawing machine, also known as the copper tube drawing machine, can be used to stretch the copper tube, so that the copper tube with the required outer diameter and wall thickness can be obtained. [0003] At present, the authorized announcement number is CN201324760Y, and the Chinese patent issued on October 14, 2009 discloses a profile hydraulic stretching machine, which includes a machine base, a drawing die base arranged on the machine base, a bed, a set The guide rail and drawing device on the bed, the idler device, the translational discharge device of the chain drive, and the sawing device at the exit of the drawing die base. The drawing device includes a drawing trolley, a four-link clamp device installed on the drawing trolley to clamp the flat material, and a...

AI Technical Summary

Problems solved by technology

[0004] The copper pipe needs to be headed before drawing to form a relatively flat head, so that the four-link clamp device on the drawing trolley can clamp the head of the copper pipe and then pull it. After the four-link clamp device on the drawing trolley clamps the head, when the drawing trolley moves, the pulling force on the copper pipe is relatively large, because the head is squeezed by the head making machine, The connection strength between the head and the copper pipe is relatively reduced, which may easily cause the head on the copper pipe to break

In this case, generally, the part of the head that was originally used to connect the copper pipe is hit with a hammer, so that the caliber of the part that was originally used to connect the copper pipe is reduced, and then inserted into the copper pipe, and finally passed through the hammer. The copper pipe will be knocked so that the caliber of the copper pipe part is reduced and pressed against the head, and finally stretched, but at this time, the connection strength between the head and the copper pipe is poor, and when stretching It is still easy for the head to be detached; if the copper pipe is moved to the head making machine for head making, the copper pipe is set on the drawing rod of the drawing machine, and its length is long, remove the copper pipe again Then make the head, the operation is more troublesome
