    Method and apparatus for the surface working and for reworking, or reshaping, of elongated workpieces. A strike bolt strikes the inner side of the curvature of the workpiece at high frequency to apply a plurality of strikes to the workpiece. Measurement of the straightening of the curved workpiece occurs directly on the worktable, preferably by means of air-jet nozzles, which are connected to indicating tubes.

    专利说明:

    The invention relates to the processing of pressure flat parts for their alignment. There is a known method of straightening flat parts, in which the product is subjected to a series of blows of an instrument, and a device for carrying out this method, comprising a support table mounted on the base and a rack carrying a firing pin located beneath the table, 1J, the disadvantage This solution is a low quality of processed products. The purpose of the invention is to improve the quality of products. . To this end, in the straightening method, in which the product is subjected to a series of tool beats, the blows are made on the concave side of the product in the direction from the most curved. plots to the least curved, and in the device for carrying out this method, comprising a table and a rack, bearing a power head placed above the table, the working surface of the latter is curvilinear. . It can be made as part of a sphere. Or as part of a circular cylinder. The working surface of the support stand can be made in the form of a prism. She can also be executed in. as a flat plate; in which at equal distances from each other parallel through channels are made, extending at one end to the working surface, and the device is equipped with a product plane sensor formed as a pressure source and partially filled with working fluid i-shaped tubes, each of which has one end is sealed, and the other end is connected to a pressure source and to the second end of the corresponding CKBCisHoro channel. FIG. -1 schematically shows the processing method :; in fig. 2 - device, common yid; in fig. 3 shows the mechanism for measuring the air gap of the article and the support table. The product 1 is placed on the supporting table 2, fastened on the base of the CW. With the help of the lock 4, the hammer 5 is used to strike the concave side of the product 1.
    With different strengths. Hammer 5 is mounted on a rack 6 with the possibility of reciprocating vertical adjustment movement. The support table 2 can be made in the form of a prism (Fig. 2), which serves as a support for the product 1. As the hammer 5 any mechanism can be used by means of which a series of blows are produced. The impact occurs when the drive shaft 7 through the cam 8 and the spring 9 actuates the striker 4. The oscillations of the support table and the base when the hammer is briskly perceived by shock absorbers 10. For comparative measurements of the plane of the product, the support table 2 is used in the form of a flat plate (Fig. 3 ) The glass V-tube 11 is partially filled with tinted working fluid 12. The end 13 of this tube is sealed. The other end of the tube is connected to the air duct 14. A pulse is supplied from the pressure source 15 through the throttle 16. One branch of the air duct 14 goes to Tps / tank 11 through the safety valve 17, and the other branch of the air duct 14 is directed to the through channel nozzle 18 2. The nozzles are distributed evenly over the entire surface of the support table. Each nozzle 18 corresponds to its own pipe 11.
    - Relative measurements are made as follows.
    A pressure of about 1 bar is transmitted from the pressure source 15 via the air line 14. By means of the throttles 16, the pressure is reduced to 0.5 bar. If the air gap 19 between the product 1 and the supporting table 2 is almost zero, then air will not escape from the nozzle 18. Air pressure rises. The total pressure in the air duct 14 affects the fluid 12 in the tube 11. The fluid in the open end of the tube descends to zero (Fig. 1), showing the absence of a gap and compression of the gas in the closed end 13 of the tube. If the product is bent, air escapes from the air cap 19, as a result of which, at the open end of the tube 11, the pressure drops, and the liquid 12 at this end rises. The difference between the fluid levels in the open ends of the tubes makes it possible to determine the deviation of the plane of the product 1 from the plane of the support table 2. Depending on the size of the bend, the material and the external dimensions of the product, the number of impacts, their strength and the radius of curvature of the striker are selected.
    Example. A solid ingot with a yield strength of 62 R, rectangular cross section, 26 cm long and 12.5 cl wide, with a bend of 0.3 mm, is taken as the sample. Edit
    produced to an ingot curvature of 0.03 mm. Several identical samples are processed by strikes with radii of different curvature (from 2 to .5 mm) with increasing force. The number of beats in each series is 150, and the frequency of beats is 50 beats per second.
    It turns out that with a larger radius of curvature of the tip of the striker, a longer time is required to work, however, the deepening in the surface of the part in this case is less. The same result is obtained with a smaller impact force (the impact force corresponds approximately to a blow from the hand). The top of the striker is made in the form of a sphere or may have a circular cylindrical shape, so that the blow comes not in a point, but in a line. Approaching, lifting, fixing and retracting the hammer with a pick is made from the pneumatic actuator. The impact force, their number and duration are regulated by means of an electronic control circuit. Experiments have shown that after processing the hardness of the product is 64-67 RJ., Which exceeds the initial. The frequency of strikes 50-120 per second is rational, the optimal number is 30-600, mainly 60-350.
