SU1636251A1 - Rotor of rotary machine - Google Patents

Abstract

The invention relates to mechanical engineering, namely to the design of rotors of rotary machines. The purpose of the invention is to improve the quality of products. The rotor has drums 3 and 4 with tool kits and sliders 8 installed in them. In sliders 8, wedges 9 are mounted for radial movement with rollers 13 interacting with a fixed cam 10 and spring 11 with respect to the base 1 with spring cam 12. Procurement 14 is fed into a die 6, when the ejector 7 is in the lower position. The punch 5 is installed in a fixed position relative to the end face of the matrix 6. By moving the wedge 9 from the spring-loaded copier 12, the ejector 7 lifts the workpiece 14 all the way into the punch 5, metering the volume of the part of the workpiece protruding from the matrix 6 regardless of the total length of the workpiece 14. The punch 5 deforms the workpiece 14 and rises. Pusher 7, moving together with the slider 8, pushes the product out of the matrix 6. The stationary copier 10 returns the wedge 9 from the center to the periphery. The slider 8 also descends to its original position. Thus, with fluctuations in the length of the workpiece, the volume of its disembarked part is constant. 1 il. at i

Description

The invention relates to mechanical engineering, namely to the design of the rotors of rotor machines.

The purpose of the invention is improving the quality of products. 5

The drawing shows a diagram of the working rotor.

The rotor contains a bed 1, a drive shaft 2 with drums 3 and 4, on the periphery of which are sets of tools from a punch 5, a matrix 6 and an ejector 7. In the drum 3 there are also drive sliders 8 with wedges 9 mounted on each working position with the possibility of return - translational movement in the radial direction.

The drive radial movement of the wedges 9 is made in the form of a copier 10 mounted on the frame 1 to move the wedges 9 from the center of the rotor to the periphery. For 20 movement of the wedges 9 from the periphery to the center of the rotor, the latter is equipped with a spring 11 of a copier 12 spring-loaded relative to the frame 1. Rollers 13 are installed on the wedges 9 for interaction with the copiers.

The rotor operates as follows.

The blank "14 is fed into the matrix 6 until it contacts the ejector 7, for example, using a punch 5. The punch 5 30 returns to the position corresponding in height from the end of the matrix 6 to the beginning of stamping. At this moment, the ejector 7 occupies the initial position at which the height of the exposed part of the workpiece from the 35 matrix 6 is less than the required.

When the drums rotate, the wedges 9 installed in the drive sliders 8 interact through the rollers 13 with a copier 12, spring-loaded to the frame 1 by springs 40 11. The wedges 9 move from the periphery to the center, push the ejector 7 and the workpiece 14 all the way, for example, into the punch 5 .

The course of the wedges 9 is determined by the course of the springs 11, which at the moment of contact 45 of the workpiece 14 with the punch 5 should provide a force on the ejector 7, not exceeding the calculated value.

During the stamping period, the workpiece 14 rests on the ejector 7, which interacts through the wedge 9 with the slider 8. The slope of the wedge 9 is chosen equal to the angle of self-braking.

After stamping, the product is pushed out of the matrix 6, informing the axial movement of the slider 8 to the ejector 7 together with the wedge 9. The axial movement of the slider 8 is equal to the length of the core part of the product stamped in the matrix 6.

With further rotation, the roller 13 interacts with the stationary copier 10 and the wedge 9 makes a return movement from the center to the periphery of the rotor. Then the slider 8 returns the ejector 7 with the wedge 15 9 to its original position. ' The cycle is over.

This embodiment of the stamping rotor provides an individual axial feed of each workpiece with a force excluding its deformation and bending before stamping, which allows to maintain the constancy of the length of the exposed part of the workpiece from the matrix, compensating for the length errors of piece blanks.

The economic effect in the implementation of the invention is achieved by improving the quality of products.
