Description

(54) CHIMPER

one

The invention relates to mechanical welding equipment that can be used in the manufacture of large flat and corrugated panels, as well as panels with welded stiffeners.

Known tilter containing mounted on the basis of the toothed rack and the carriage mounted on JQ her two semi-axes, equipped with pivoting levers that interact with the rack l.

However, the well-known tilter has a complex mechanism for turning the levers, including gear sectors, gears, rails, springs, and does not provide for the turning of large-sized products due to the substantial growth of the hydraulic cylinder 20 and the gear sector, as well as significant loads on the gear teeth.

Also known is a cantilever containing feed and take-over pivoting levers with gear wheels interoperating with a movable gear rack, the lever lever being mounted for rotation at an angle OL 90 and receiving at an angle (L 180 ° g / G21 .30

The mechanism of rotation of the levers of this turner is also complex, since it contains a toothed rack and gears, the presence of which limits the weight of the turned-over items.

The closest in technical essence and the achieved result is a tilter containing a bracket with two levers hinged to it and a power cylinder for turning these levers, the stem of which is connected to one of the levers Z.

However, in this positioner, it is possible under the weight of the product, spontaneous rotation of the levers, not limited to any stops, and, consequently, their jamming.

The aim of the invention is to prevent jamming and spontaneous rotation of the levers under the action of the weight of the product.

For this purpose, the power cylinder body is pivotally mounted on the second lever, and latches are mounted on the bracket, sequentially interacting with each of the levers.

FIG. 1 isobrsoken offered tilter, in the plan; in fig. 2 is a section A-A in FIG. 1; in fig. 3 is a section BB in FIG. 2, the tilter contains a carriage 4 mounted on the base 1 with the possibility of movement in the guides 2 by means of the rollers 3. The drive of the carriage 4 is made in the form of a hydraulic motor 5 with wagons with an asterisk 6 connected to the carriage 4 of the chain 7. The tensioning chain A bracket 9 is mounted on the trolley 4, on the axis 10 of which two double-arm levers 11 and 12 are articulated with supports 13 and 14 for the product. One of the arms of each lever is intended for laying the product on it. On the lever 12, a power cylinder 15 is pivotally mounted, the rod of which is pivotally connected to the lever 11. On the bracket 9 of the carriage 4, clamps 16 and 17 with hydraulic cylinders are installed to successively fix the levers. The stroke of the power cylinder 15, the location of the hinges securing its body and stem on the levers 11 and 12, as well as the location of the latches 16, 17 are chosen so as to provide the angle of rotation of the lever 12 through an angle of 90 ° C and lever 11 through an angle (L 180 ° "I. The tilter works as follows. In the initial position, the tilter is in the leftmost position, with the arm 11 for receiving the product at an angle (b to the horizontal plane and fixed by the lock 16, and the arm 12 for feeding the product horizontally. Belt served n and the bearing surface of the lever is 12, and the power cylinder 15 is turned on. When the stem of the power cylinder 15 is extended, the lever 12 together with the panel rotates about an axis about 90 ° relative to the axis while the panel is supported by the end 14 on the stop 14. By turning the lever 12 it is fixed 17, and the panel is placed between the levers 11 and 12. The hydraulic motor 5 is turned on, and the tilter, by means of a chain transmission, moves on the trolley rollers along the guide rails 2 to the extreme right position. Then the latches 16 are turned off, the power cylinder 15 is turned on to pull the rod, and the lever 11, together with the panel resting on the stops 13, is rotated from the axis 10 to a horizontal position, after which the turning process ends. After removing the cloth from the position, the receiving lever 12 is again raised at an angle p, fixed, the hydraulic motor 5 is turned on, the tilter moves to the leftmost position, the feeding lever 12 unlocks, lowers to the horizontal position, and the tilter is ready for the next turning cycle. The use of the invention will reduce the cost of making the turner, since there will be no need to manufacture gear sectors, gears and rails of large dimensions, it will facilitate the installation of the turner in connection with the fact that its rotation drive consists of one power cylinder with locks, the installation of which does not require that high assembly accuracy, which is necessary when installing gears. Simplifies the maintenance and repair of the turner, increasing the reliability of its work. In addition, the design of the zucci will facilitate the removal of the panel from the tilting device, since the panel rotates into a vertical position and can move in this position throughout the working position to the place where it is convenient to remove it with a crane. The invention The tilter containing the arm with pivotally attached levers on it and the power cylinder to rotate both levers, the stem of which is connected to one of the levers, so as to prevent jamming and spontaneous rotation of the levers under the weight of the product, the body of the power cylinder pivotally mounted on the second lever, and on the bracket mounted clamps, consistently interacting with each of the levers.
