Description

Technical Field

[0001] The present application relates to the technical field of copper tube processing machinery, and in particular to a blanking mechanism of a straight drawing machine. Background Art

[0002] Copper tube, also known as red copper tube, is a kind of non-ferrous metal tube, which is a pressed and drawn seamless tube. Generally, the production workshop uses a straight-drawing machine to straighten the copper tube. During the straightening process, the diameter of the copper tube becomes smaller and the tube wall becomes thinner under the action of the straightening die, meeting the size requirements of the product for the copper tube; through the plastic deformation of the material, the strength of the copper tube is improved and the surface becomes brighter.

[0003] The following problems were found in the actual production process: because the existing straight-pull machines mostly use chains for transmission, the copper tube is located just above the chain or track of the straight-pull machine. After the copper tube is straightened, it will fall straight down and needs to be caught and taken away manually. If there is no one at this station, the copper tube may be damaged and scratched, affecting the surface quality of the copper tube. After the copper tube is straightened, it still needs to be taken away manually for placement. Therefore, the existing straight-pull machine production cannot achieve unmanned operation or reduce manual labor, and the manual labor intensity is not low, requiring high labor costs, and the manual labor efficiency is low, which cannot provide production efficiency. Therefore, the current production method cannot meet the production needs of high quality, high efficiency and low cost. Utility Model Content

[0004] In order to solve the problems existing in the existing straight-drawing machine production, improve the production quality and production efficiency of copper tubes, and reduce labor costs, the present application provides a straight-drawing machine unloading mechanism.

[0015] Optionally, a position sensor is provided on the straight-drawing machine near the maximum stroke position of the drawing trolley.

[0016] By adopting the above technical solution and setting the position sensor, when the drawing trolley moves to a position close to the maximum stroke, that is, when the copper tube is about to be drawn, the position sensor detects the presence of the drawing trolley and transmits the detection signal to the host computer. The host computer controls the operation of the power component to drive the cross plate to rotate to the bottom of the copper tube, ready to receive the copper tube that has been drawn.

[0017] Optionally, the transverse plate and the material storage rack are arranged on the same side of the straight-pulling machine.

[0018] Optionally, the transverse plate and the material storage rack are respectively arranged on both sides of the straight-pulling machine.

[0020] Optionally, flexible belts are provided at both ends of the material storage rack, and a PE tube is sleeved on the flexible belts.

[0021] By adopting the above technical solution, the flexible belt is set up, which has good flexibility, plays a vibration reduction role, and reduces collision damage. Since there is oil on the surface of the copper tube, the flexible belt is easy to clean by sleeve-installing a PE tube.
