Abstract

The exemption relates to the field of forge-and-press engineering, in particular, to the design of the mechanisms for adjusting the die press space. The purpose of the invention is to increase reliability. Increased reliability is ensured by the absence of a gap when the press operates between shaft 4 and gear 8 or gear 3, as well as the presence of a phase sensor 24. The sensor is connected by a lever 25 to a slider 10 and electrically via a communication system 26 with means 27 for controlling the operation of the reversing electric motor 1 and the unit 28 digital display and pre-selection. Reliability is achieved by eliminating friction pairs in an idle adjustment mechanism when the press is performing a process operation.

Description

The invention relates to the field of forging and pressing machine-building 1 and, in particular, to the design of the mechanisms for adjusting the stamping space of a press.

The purpose of the invention is to increase reliability.

Figure 1 shows the proposed mechanism, a general view; figure 2 - section aa in Fig .; FIG. 3 is a block diagram of the device; figure 4 - node I in figure 1; figure 5 - section bb in figure 4.

The mechanism for adjusting the press space of a press consists of a reversing electric motor 1 mounted on a bed of a press 2, a gear bed 3, a shaft 4 housed in supports 5 and 6 mounted on a bed 2, and part 7 of shaft 4 is made up of (Fig. 1 and 2) or shaped profile (figure 4 and 5). On the shaft 4 there is a lestern 8, which is rotatably fixed in the crown 9, rigidly connected to the slider 10 of the press. The gap Z between part 7 of the shaft 4 and the gear wheel of the pair 3 (Figures 4 and 5) or part 7 of the shaft 4 and the walls 8 (Figures 1 and 2) is chosen in such a way as to prevent contact between them during the operation of the press. In bracket 9, there is an N1 satellite-satellite 11 which meshes with gear 8 and a gear wheel 12 located in a slider 10 and bounded by a ring 13 and a lid 14. A spherical head 15 uiTOKa 16 is placed in the hole of a gear wheel 12, limited from vertical displacement a baffle 17, an insert 18 and a nut 19. The pin 20 is pressed into the spherical head 15 of the stem 16 and placed in the so-called 21 gear wheel 12. The stem 16 with its threaded part 22 is connected to H1 Patun 23. On the base 2 there is a fixed synchro sensor 24, connected by a lever 25 s to with a slider 10 and electrically by means of a communication system 26 with the means 27 for controlling the operation of the reversible motor 1 and the digital indication and preset unit 28.

The adjustment mechanism die space press works as follows.

Torque from electric motor

through gear pair 3. gears 8 and 11 gear wheel 12, as well as pin 20 is transferred to QJTOKy 16, the threaded part 22 of which, screwing (or unscrewing) into the connecting rod 23, changes the value of the die space I. either manually, by pressing the start button (not shown) of the electric motor and observing the reading of the measuring space of the shtamnovo space (not shown), or using a pre-dial

the required value I in the pre-dial and digital display device, coupled with the control means 27, which, after receiving the corresponding signal via the communication system 26 from the phase sensor 24, gives a command to stop the electric motor 1.

The provision of the required clearance Z after the adjustment is made is provided by the command of the control means 27 of the electric motor 1 to reverse for a specific number of revolutions (or operating time), ensuring that it returns the shaft 4 to the neutral position.

During ripecca operation or its adjustment, i.e. during reciprocating movement of the slider 0, gear wheel 8 moves along part 7 of shaft 4 (figure 1) or part 7 of shaft 4 moves along gear pair 3 (figure 4) without mutual contact due to the gap between them Z.

In the process of operation of a press with a large level of vibration, it is possible that the unscrewing of the threaded part 22 of the rod 16 from sch 15 at 23, which can lead to an unacceptable change in the size of the stamp space N. In this case, the phase sensor 24 transmits the actual value I 27, which transmits a command to the motor J to change (correct) the Yado value of the value indicated in preset 28. Correction is carried out with the slider 10 stopped.

The technical and economic effect of the implementation of the invention in comparison with the known machine model is ensured by improving reliability by eliminating friction pairs in the idle adjustment mechanism when the press performs a technological operation, which increases its durability due to the absence of rubbing surfaces.
