The invention discloses a coil rubbing device. The coil rubbing device is characterized by consisting of a base, left and right rubbing arms, a rubbing arm power mechanism, a return cylinder and a compression spring, wherein the rubbing arm power mechanism is provided with a first rotating wheel arranged on the base through a bearing; the first rotating wheel is provided with the left and right rubbing arms; one end of the left rubbing arm is connected with the first rotating wheel, while the other end is hinged with the left rubbing arm; one end of the right rubbing arm is connected with thefirst rotating wheel, while the other end is hinged with the right rubbing arm; the cylinder body of the return cylinder is fixed on the left rubbing arm; a piston push rod of the return cylinder is fixedly connected with the right rubbing arm; and the compression spring is connected between the cylinder body of the return cylinder and the piston push rod. The coil rubbing device has the advantages of rubbing and pressing the original coil rapidly and effectively, improving the consistency of products, providing stable and reliable coil sheets for the subsequent rounding process, and having stability and reliability, long service life and high precision.
