Description

The invention relates to the field of press-forging equipment and can be used for feeding into a press blanks with an elongated axis. A device for feeding blanks with an elongated axis to an horizontal pressure press is known, which is installed in the frame guides and made in the form of a hollow box. the side walls of the transfer prism for blanks, the drive of the reciprocating movement of the carriage in the direction of sub chi, placed in the opening of the frame and mounted on a vertical pant, lifting from an individual drive bracket with mounting prisms for workpieces, as well as an adjustable stop fixed to the rod, which interacts with the end of the gesture connected to the frame of the body and guides the 1 hub sleeve covering the rod of the lJ. However, with a known device, it is impossible to carry out the subsequent removal of the workpiece with the thickening obtained on it. The purpose of the invention is to provide the possibility of subsequent removal of the mortar. thin with thickenings. . For this, the device is fitted with mounted on the carriage opposite to the feed axis rotary, spring-loaded calibrated plates, which fit into the working position between the end of the body of the guide bush and the adjustable stop. FIG. 1 shows a device for feeding blanks to a press; general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - section B-E in FIG. 1 (when pushing the workpiece); in fig. 5 - the same (when pushing forgings). The device comprises a carriage 1 mounted on rails 2 mounted on brackets 3. Carriage 1 is made of box-shaped with free internal space G. With axis 4 and eyelets 5, the carriage is connected with rod b of reciprocating drive cylinder 7. The cylinder 7 is mounted on the bracket 8 and has a wound D and a rod E cavity. For laying the blanks 9, the carriage 1 inside the space G has interchangeable prisms 10, which are mounted on the side walls of the carriage with the help of fastening means 11-13 on the side walls with the possibility of vertical adjustment. Vertical movable lifts 14 are located at the working positions, which with the help of rack-and-pinion gear (rail 15, gears 16 and 17, horizontal gear rail 18) interact with the rod 19 of the power cylinder 20 (drive for raising and lowering billets having rod stock and piston And the cavity. The cylinder 20 is mounted on the bracket 21. The elevator 14 has a damping device made of a fixed thrust washer 22, a spring 23 and a movable flange 24.

 The movable flange 24 is mounted on the lift 14 with the aid of a hole K and mounted on it with the possibility of vertical movement by means of a finger 25 and a vertical groove.

On the movable flanges 24, a bracket 27 is mounted by means of the fastener 26, which connects the lifts 14 to each other. Plank 27 bears on itself a guide rod 28, which is housed in a guide sleeve 29, mounted on the frame 30 by means of a bracket 31. At the end, the rod 28 has a thread 32 on which a cam 33, screwed in the form of a nut, and one butt end periodically interacting with rigid stop 34, which is the body and bracket on which guide sleeve 29 is mounted, and the other end periodically interacting with calibrated plates 36 placed on adjustable along the height of the bracket 3.7 mounted on the carriage 1 by means of the fastening means 38 and 39. The plates in the extreme position and interact with the adjustable stop 40.

On a spring-loaded bar with the possibility of longitudinal adjustment, a bar 41 is installed, on which mutually moving brackets 42 are mounted with transverse adjustment. On the side vertically arranged brackets 42 by means of fastener 43 with vertical-mountable mounting, two pairs of lifters 14 are installed in pairs; 1 9 cylindrical, stepped or solid form.

The proposed device has a loading and unloading position and two working positions, on which the mobile 45 and fixed matrix 46 are located, equipped with ejectors 47 and 48. The unloading tray 49 is installed at the unloading position.

The device works as follows.

The carriage 1 is in its initial position at the loading position where, using a loading device (not shown), the blank 9 is placed on the prisms 10. The elevators 14. are in the lower position, and the prisms 44 are below the prisms 10. The spring-loaded swivel plate is under the rigid stop 34. Pressure is supplied to the piston cavity of the actuator cylinder 7, reciprocating movement and movement through the rod 6, the axis 4 and the lugs 5 is transmitted to the carriage 1 which moves to the left and transfers the workpiece 9 to the working position. Then

5, pressure is supplied to the piston cavity of cylinder 20 and movement through rod 19, rail 18, gears 17 and 16, rail 15 is transmitted to elevators 14 that move upwards, prisms

Q 44 remove the workpiece 9 with prisms 10 and lift them into the working areas of the matrices 45 and 46 of the press. The guide rod 28 is mounted on a spring-loaded bar 27, moving

f in the sleeve 29, provides an additional direction to the lift 14, and the cam in the upper position, resting against the rigid support 34, butts up the rigid exact coaxial position of the workpiece 9 relative to

In the matrices 45 and 46. When the movement of the movable matrix 45 is an exact pushing of the workpiece into the matrix, holding and clamping the workpiece. After that, the pressure in the rod

5, the cavity of the cylinder 20 and the lifts together with the prisms are lowered and the carriage returns to its original position. In this case, the spring-loaded swivel plates are suitable for rigid

Q emphasis 34. The matrix 45 under the action of technological effort, moving, produces a technological operation (reduction and disembarkation of the head), after which it reverses. Billet 9 remains in

one of the matrices.

The pressure in the piston cavity of the cylinder 20 is applied, and the lifts 14 are raised. In this case, the guide rod 28, mounted on the spring-loaded bar 27, moving in the sleeve 29, guides the lifts 14. In the upper position, the cam 33 rests against the turn plates 36, which interact with the rigid stop 34, and the prisms of the lifts do not gain to the original position by the thickness of the turntable, which is selected depending on the size

thickened upset head. Next, the ejector produces the ejection of the workpiece from the matrix. In this case, the prisms are below the thickening of the diameter of the upset head and do not interfere with the free movement (ejection) of the workpiece. The blank, without touching the prisms, is pushed out of the die with the help of pushers and placed on the prisms of the lifts. After that, pressure is supplied to the rod cavity W of cylinder 20 and movement through rail 18, gears 17, 16, and rail 15 is transferred to lifts that lower the blanks 9 to prisms 10 of carriage 1, while continuing to move downwards, freeing up space for moving carriage 1 to the left . At the loading position, the next loading of the workpiece occurs. Upon further movement of the carriage 1 to the left, the finished workpiece 9 is transferred to the next position. The process of loading, lifting into the working area, clamping, pushing, pushing, lowering, transferring the workpiece from one position to another is repeated.

After processing of the workpiece 9, it is unloaded at all positions.

The lift arm 14 fits under the finished workpiece and, when it moves upward with its inclined planes, pushes the workpiece upwards. The workpiece ck attaches along the inclined planes of the lever of the lift 14 to the inclined unloading tray 49, from where it enters the container.

To set up and accurately set the workpiece 9 in the working area in relation to the dies 45 and 46 in the automatic cycle, lift the prisms 44 into the work area, lay the workpiece 9 on them, release the fasteners and move the strap 41 together with the prisms 44 and the workpieces 9, expose them horizontally with respect to the matrix.

In the vertical position of the prism 44 along with the blanks are exposed

by raising and lowering them in the grooves of the fastener, for which it is necessary to release and then tighten the fasteners 43. In the longitudinal direction of the prism with respect to the workpiece is also exposed by moving the grooves of the brackets 42 together with the prisms 44. In this way, installation of blanks with prisms at work sites.
