[0002] The silver-copper alloy rods made of silver-copper alloy are rolled in holes after car stripping, and then drawn by a large horizontal wire drawing machine. During the wire drawing process of the large horizontal wire drawing machine, when the wire passes through the mold, the wire becomes Thin, the wire is drawn into a ring shape. At the end of each drawing, due to the tension of the drawn wire, the drawn wire will be hit on the large lying wall, which is easy to cause damage to the surface of the wire, such as increased burrs and surface damage. It is easy to form cracks, so that moisture and grease in the air enter the surface of the wire, which increases the process of continuous thinning and causes burrs and surface dirt on the wire surface

The invention relates to an improved silver-copper alloy wire drawing device. The improved silver-copper alloy wire drawing device comprises a support, wherein guide rails are arranged on the support in parallel, a wire drawing baffle is fixedly connected to the guide rails and is provided with a conical wire drawing die; a traction trolley directly facing the baffle is erected between the guide rails and comprises a locating block; a groove in the shape of 'REN' (like a Chinese character) is formed in the locating block; clamping blocks are symmetrically arranged in the 'REN'-shaped groove; the rear ends of the clamping blocks are connected to a push rod, the rear side wall of the locating block is fixedly connected to a guide rod; a push block is slidably connected to the guide rod and is connected to a first air cylinder; a first connecting rod is slantwise arranged on the locating block and is in pin joint with a second air cylinder; the rear end of the traction trolley is in pin joint with a drag hook; the second air cylinder is in pin joint with the drag hook through a second connecting rod; a transmission chain is arranged between the two guide rails. The improved silver-copper alloy wire drawing device is simple in structure, can be used for drawing a silver-copper alloy wire into a straight line and improving the surface quality of the wire, has high efficiency and is low in production cost.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a device for drawing silver-copper alloy rods. Background technique [0002] The silver-copper alloy rods made of silver-copper alloy are rolled in holes after car stripping, and then drawn by a large horizontal wire drawing machine. During the wire drawing process of the large horizontal wire drawing machine, when the wire passes through the mold, the wire becomes Thin, the wire is drawn into a ring shape. At the end of each drawing, due to the tension of the drawn wire, the drawn wire will be hit on the large lying wall, which is easy to cause damage to the surface of the wire, such as increased burrs and surface damage. It is easy to form cracks, so that the moisture and oil in the air enter the surface of the wire, which increases the process of continuous thinning and causes burrs and surface dirt on the surface of the wire.
