Ejecting device for cold heading machine

Abstract

The invention discloses an ejecting device for a cold heading machine. The ejecting device comprises a rack; the longitudinal section of the rack is in the shape of a hollow rectangle; a receiving boxis glidingly connected to the inner wall of the bottom of the rack; a first air cylinder is fixedly mounted on the outer wall of one side of the rack; a second air cylinder is fixedly mounted on theouter wall of the other side of the rack; a heading block is welded on the inner wall of one side, close to the second air cylinder, of the rack; a first piston rod is perpendicularly and movably connected in the middle of the outer wall of one side, close to the second air cylinder, of the first air cylinder; a second piston rod is perpendicularly and movably connected in the middle of the outerwall of one side, close to the first air cylinder, of the second air cylinder; fixing sleeves are arranged at the ends, close to each other, of the first piston rod and the second piston rod; and thefirst piston rod is fixedly connected with a pressing rod through the corresponding fixing sleeve. The ejecting device integrates ejection and receiving, the machining efficiency is high, the chargingoperation is simple and convenient, and the ejecting device is convenient to use by people.

Description

Technical field [0001] The invention relates to a topping device for a cold heading machine. Background technique [0002] The top of the bar or wire processed by the cold heading machine will show a thickening forming effect, which is mainly used to manufacture parts such as bolts, nuts, nails, rivets and steel balls. The ejector device in the cold heading machine is used as the driving body and the control rod The movement of the material and the upsetting parts to complete the cold heading is an important working mechanism in the cold heading machine. When the traditional ejector device is in use, the inability to receive the material in time affects the processing efficiency. At the same time, it is inconvenient to insert the bar material. The complicated operation brings troubles to people's use and affects the use of the ejector device. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the present invention provides a topping device for a cold h...

[0002] The top of the bar or wire processed by the cold heading machine will show a thickening effect. It is mainly used to manufacture parts such as bolts, nuts, nails, rivets and steel balls. The ejector device in the cold heading machine is used as the driving body, and the control rod It is an important working mechanism in the cold heading machine to move the material and the upsetting parts to complete the cold heading. When the traditional lifting device is in use, it cannot receive the material in time, which affects the processing efficiency. At the same time, it is inconvenient to put the bar and feed The operation is relatively complicated, which brings troubles to people's use and affects the use of the ejector device.
