Description

(54) TIGHTENING MACHINE of the lower section of the Slider 10., inside which the hydraulic cylinder 11 is located, which is connected to the housing by the bracket 12. A hydraulic cylinder 13 is attached to the back wall of the slider, which is used to move the claws to the longitudinal stretching of the workpiece horizontally. The pincers for stretching the toe part of the workpiece consist of fixed and movable. of the jaws 14 and 15 mounted in the housing 16 on the hype 17, which is clamped, by the tangential clamp 18 in the guide 19, having the possibility of a swinging movement in the direction of the pad. The position of the tongs relative to the pad is adjusted by a screw 20. On the sleeve 17, a hydraulic cylinder 21c is moved with a 1H body, having a pin 22, with which through a pin 23 they are clamped. The jaws are opened by a spring 24. The middle flares are installed in the housing 25, which can be raised vertically. A gear-wheel with i 26 mounted on the shaft, which is rotated by the handle 27, engages with the housing rack. The tongs can swing in two mutually perpendicular planes, along and across the pad for longitudinal and transverse cross-section out the same blank. Clamps for stretching the beam part of the logging are similar in design to the middle tongs and are mounted on a gear wheel connected to a ruyuk. With the latter, they can be rotated to fold the edge of the workpiece onto the bundle portion of the insole. Tightening plates are installed in the sleeves between the two joined plates 28 and 29, which are axially guided in the slot of the slide 30. Moving the tightening plates is carried out by a hydraulic cylinder 31, on the stem of which the rocker 32 is fixed by fcj rollers 33 interacting with the copier (in the drawing depicted). With the help of rollers and a copier, the tightening plates with the springs 34 are lowered onto the block during tightening. A hydraulic cylinder 35 mounted on a frame and connected to the slide 30 by a bracket 36 is designed to move the plates into the working area of the machine. The position of the tightening sheaths relative to the pad mounted on the fan is adjusted in height by special screws. The machine works as follows. The cam 37 of the camshaft 38 acts on the Hia switch and turns on the electric motor 39, which, through two worm gears and interchangeable gears of the gearbox and chain drive, transmits the rotation to the camshaft 5c by cams 40-44. The cams 40 and 42, through the zo-go of the hydraulic system, give the command to lower the exhaust head 3 to the working position by means of a hydraulic cylinder 11 and move in the direction of the boat using the hydraulic cylinder 13. Thereafter, the electric motor is turned off. Next, the edges of the billet are manually loaded into the tongs and, through the pedal, turn on the control mechanism 45, the cam of which actuates the cam 4b acting on the control spool lever, providing oil supply to the hydraulic cylinders 21 of the tongs. In this case, the nose part of the workpiece is first clamped with jaws, and then the remaining tongs come into action. The yoke 47 is lowered onto the insole and the exhaust head automatically moves in two directions: in the direction from the shoe in the horizontal plane and upwards. In this case, with the help of cylinders 11 and 13, longitudinal stretching and lateral stretching of the workpiece are carried out. With cross-coating roller 48 uphill. into the cam 49, moves the rail 5O and, through the gear wheel 51, turns the pliers to pull the beam part of the bogie onto the shoe. ; When the side of the workpiece is finished, the machine stops. At 52, the quality of the wrapping is checked and, if necessary, with the aid of the handle 27, they act as pincers and make additional dressing of the workpiece. After that, the pedal is pressed, and the cam 53 is commanded to turn on the electric motor. The cam 42 includes a cylinder 35, which moves the slider with tightening plates onto the block. Then, through the cam 43, the hydraulic cylinder rod is moved, on which (the box; 32, connected with the tightening plates) is fixed. When entering the flat, track contour, they are lowered onto the pad by copier 54 under the action; billet to insole. Pliers driven by the billet, swiveling in the direction of the shoe, and the yoke 47 rises and frees up space for the plates. The pliers unclench. Lift the yoke controls the cam 55 through the cylinder 56, and the unclamping broom - cam 57.; the yoke lowers off onto the plates, getting command from cam, 44. Crimping occurs, tightening the hook and gluing the top of the shoe to the insole. After the required hold, the mechanisms of the machines controlled by the cams mounted on the camshaft return to their original position and the machine stops. The block moves from the clamping machine when the conveyor moves in steps, and the machine’s working zone D comes the next block with the blank for tightening. The invented Intensive machine for wrapping and glue pulling on the soles-beam part of the shoe blank, containing an extract: the first head with 4 glasses and the tightening plates with heating elements, in order to increase the convenience operating, flared head and tightening plates are installed on the respective sliders moving them: To the treatment area with the help of hydraulic cylinders, moreover, the exhaust head is movable in horizontal and vertical directions for longitudinal and transverse stretching of the workpiece and.
