Embodiment 1

[0034] Such as figure 1 As shown, it is a kind of elongating plastic processing equipment for rolling round metal blanks provided by this embodiment. In the figure, 1 is a base, 2 is a large column, 3 is a sliding beam plate, 4 is a guide sleeve, 5 is the upper beam plate, 6 is the column fixing nut, 7 is the small guide post, 8 is the upper oil cylinder, 9 is the piston rod of the upper oil cylinder, 10 is the upper washboard tool, 11 is the round metal blank that is rubbed, and 12 is the stopper Block, 13 is the following washboard tool, 14 is the left and right sliding block, 15 is the driving cylinder, 16 is the piston rod of the driving cylinder, 17 is the supporting seat, 18 is the travel switch, 19 is the roller, and 20 roller support blocks. Such as figure 2 As shown, there are four large columns 2 and four small guide columns 7, which are symmetrically distributed around the front and back, and the upper oil cylinder 8 is installed on the symmetrical center of the u...

Embodiment 2

[0037] The difference from Embodiment 1 is that in this embodiment, two-thirds of the length of the rolled circular metal blank 11 is placed between the lower washboard tool 13 and the upper washboard tool 10, and one-third of the length extends out of the lower washboard tool 13 And the side of last washboard tool 10, the length of circular metal blank 11 2 / 3rds is carried out local rubbing and rolling and pulling out long plastic processing.

Embodiment 3

[0039] The difference from Embodiment 1 is that the middle part of the rolled circular metal blank 11 in this embodiment has one-fifth of the length placed between the lower washboard tool 13 and the upper washboard tool 10, and two-fifths of the length of the two ends are respectively Stretch out the both sides of following washboard tool 13 and last washboard tool 10, the length of 1 / 5th of circular metal blank 11 middle part is carried out local rubbing and rolling and drawing long plastic processing.

Abstract

The invention discloses a drawing and plastic processing technology and equipment for scrubbing and rolling a circular metal blank. The technology comprises the steps of firstly, placing the circular metal blank onto a scrubbing and rolling processing table board, using a scrubbing and rolling tool for pressing the circular metal blank, enabling the scrubbing and rolling tool pressing the circular metal blank and the scrubbing and rolling processing table board to produce left-and-right back-and-forth reciprocating motion, using a friction force for driving the circular metal blank to reciprocatively roll back and forth on the scrubbing and rolling processing table board, namely, scrubbing and rolling the circular metal blank on the scrubbing and rolling processing table board, and in the scrubbing and rolling process, enabling the circular metal blank to produce drawing and plastic deforming with reduced diameter and increased length. The technology provided by the invention is simple in steps, stable, reliable, convenient to operate, easy to implement, automatic in process flow, low in production cost, wide in application field, wide in market application prospect, and capable of creating a great economic benefit.

Description

technical field [0001] The invention relates to the technical field of metal plastic processing, in particular to an elongating plastic processing technology and equipment for rolling round metal blanks. Background technique [0002] The application number is CN201811536419, and the invention name is "the drawing method of free forging". The Chinese invention patent application of Xingtai Delong Machinery Roll Co., Ltd. provides a drawing method of free forging, which is obtained by drawing a blank whose diameter is the initial size. The target forging whose diameter is the target size includes the following steps: blanking to obtain the billet whose diameter is the initial size; heating the billet to the initial forging temperature of 1150-1250°C; flattening the billet to obtain the first intermediate Forgings, the distance between two opposite planes of the first intermediate forging due to being flattened reaches an intermediate size, and the intermediate size is smaller ...
