Unloading device for cold drawing machine

Abstract

The invention discloses a discharging device of a cold-drawing machine. The discharging device comprises a material stop column, one drive discharge trolley and a plurality of driven discharge trolleys; the discharge trolleys are connected through a connecting part; the drive discharge trolley and the plurality of the driven discharge trolleys are connected onto a rail frame in a sliding manner; the rail frame has a starting end and a stop end; the material stop column is arranged on a position close to the starting end; the plurality of the driven discharge trolleys and the drive discharge trolley are sequentially arranged; each of the drive discharge trolley and the driven discharge trolleys comprises a trolley body, a swing arm shaft and a discharge arm; an elastic part is arranged between each discharge arm and each trolley body; the drive discharge trolley is equipped with a power receiving mechanism; and the power receiving mechanism is connected with a drive chain wheel shaft through an intermediate transmission mechanism. With the adoption of the discharge device, the discharge trolleys and a drawing trolley synchronously move.

Description

technical field [0001] The invention relates to a cold drawing machine, in particular, the invention relates to a blanking device of the cold drawing machine. Background technique [0002] Cold drawing machines are used to stretch workpieces (for example, steel pipes) to obtain products with high mechanical properties. The cold drawing machine includes a blanking arm, which is used to guide the cold-drawn product for blanking. In the prior art, fixed-point cutting is the main method. For example, a technical solution is disclosed in the patent with the announcement number "CN202045172U" and the name "A Swing Arm Type Steel Tube Blanking Device". The feeder realizes fixed-point feeding. In this structure, there is a lag caused by leakage caused by the cylinder drive, which will cause the pulling trolley to collide with the swing arm because it cannot be reset when it returns, resulting in mechanical failure. [0003] In addition, a technical scheme is disclosed in the paten...

AI Technical Summary

Problems solved by technology

In the prior art, fixed-point cutting is the main method. For example, a technical solution is disclosed in the patent with the announcement number "CN202045172U" and the name "A Swing Arm Type Steel Tube Blanking Device". The feeder realizes fixed-point feeding. With this structure, there is a hysteresis caused by leakage caused by the cylinder drive, which will cause the pulling trolley to collide with it because the swing arm cannot be reset when it returns, resulting in mechanical failure.

[0003] In addition, a technical scheme is disclosed in the patent with the announcement number "CN202270749U" and the name "A double-chain transmission device for upper discharge of cold drawing machine". The material mechanism realizes the upper discharge, and no technical solution is proposed to solve the upward discharge along the drawing direction
