Production equipment special for numerical control groove drum

Abstract

The invention provides a special production equipment of a numerical control grooved drum, which belongs to the technique field of numerical control milling machines, wherein, a sliding platform and a transmission mechanism are arranged on a frame, a grooved drum support and more than two sets of grooved drum motors and grooved drum jigs are disposed at the upper part of the sliding platform, a mounting rack is fixed at the middle and rear part of the frame, a jacking motor, a milling cutter motor mounting rack, a milling cutter motor and a milling cutter are arranged on the mounting rack, and the movement of the invention is controlled by a controller according to the edited program and the corresponding servo motor, and the invention has the advantages that: the production efficiency of the equipment is ten times higher than the existing equipment, but the price is only one eighth of that of the existing equipment, the lifetime of the metal grooved drum manufactured by the equipment is 8 to 10 years, the winding speed is 1300m / min, and the time of not-in-place at both ends is zero, and the invention can meet the requirements of domestic production as well as new situations of energy saving, consumption reduction and emission reduction, and enhance the competitive power of the national textile industry, and the equipment is used to manufacture various cone winding machines and parallel winding machines with different angles of taper.

Description

technical field [0001] The invention relates to the technical field of numerical control milling machines, in particular to a special production equipment for numerical control grooved cylinders. Background technique [0002] The groove drum is a key accessory for winding yarn on the textile machine in the textile industry. According to the material, the groove drum can be divided into bakelite groove drum, plastic groove drum, steel plate groove drum and metal groove drum. The working principle of the metal groove drum is winding according to friction transmission. The principle is to wind the yarn. In this mechanism, a specially treated metal grooved drum is directly driven by a DC servo motor. The axis of the yarn is rotated, the groove on the surface of the winding yarn and the drum acts as a yarn guide to make the yarn evenly wound onto the surface of the bobbin. The shape of the groove determines the law of the yarn guiding movement, and different types of acceleration...

[0002] The groove drum is a key accessory for winding yarn on the textile machine in the textile industry. According to the material, the groove drum can be divided into bakelite groove drum, plastic groove drum, steel plate groove drum and metal groove drum. The working principle of the metal groove drum is winding according to friction transmission. The principle is to wind the yarn. In this mechanism, a specially treated metal grooved drum is directly driven by a DC servo motor. The axis of the yarn is rotated, the groove on the surface of the winding yarn and the drum acts as a yarn guide to make the yarn evenly wound onto the surface of the bobbin. The shape of the groove determines the law of the yarn guiding movement, and different types of acceleration curves ensure that The required starting speed of the drum is controlled by the computer, and the transmission ratio between the drum and the yarn is controlled by the computer. When the yarn breaks, the spindle holding arm is automatically lifted, so that the drum can be separated from the surface of the drum as soon as possible, so as to avoid excessive abrasion of the yarn. The optimized groove shape design and surface treatment provide a good foundation for high-speed winding, and at the same time ensure the appearance and forming quality of the bobbins, because the groove curve of the groove drum is a combination of irregular curves and irregular arcs , it is a combination of plane and point, and ordinary three-dimensional forming technology is still difficult to solve. The foreign solution is to use large-scale CNC milling machine for processing. The disadvantages are: first, the existing equipment can only process one grooved cylinder at a time , the production efficiency is low; the second is that the equipment is expensive, and a tank processing equipment needs about 2 million yuan, which makes the unit cost of the tank remain high
