Abstract

FIELD: plastic metal working, namely, design of movable parts of HORIZONTAL hydraulic presses. SUBSTANCE: horizontal hydraulic press includes mounted on housing front and rear stationary cross pieces braced through spacers by means of columns. Movable cross piece with press plunger, container holder with container and slide with die are arranged between stationary cross pieces. Movable cross piece is pressed onto ram of working cylinder; container holder moves by means of cylinders. Lower horizontal guides, lower vertical guides and upper horizontal guides are rigidly secured to spacers. Position of movable cross piece and container holder relative to upper and lower horizontal guides and relative to lower vertical guides is adjusted by means of supports. EFFECT: enhanced accuracy of alignment of coaxiality degree of movable parts. 4 dwg

Description

 The invention relates to the field of metal forming, and more particularly to horizontal hydraulic presses, and relates to the design of the guiding movable parts of the press.

 A press is known (SU 1423213 A1 09/15/1988, B 21 C 23/00), containing the front and rear cross members mounted on the bed, pulled together by columns through spacers, between which the movable cross members and the container holder are mounted, mounted in X-shaped guides.

 The disadvantage of this design is the difficulty of aligning all the moving parts of the press.

 A hydraulic press is known ("Light metal" 1996, N 4, p. 11, Fig. 4), in which the container holder has horizontal lower adjustable guides and upper inclined adjustable guides.

 The disadvantage of this design is that when adjusting the upper inclined rails there is an additional moment, because the center of gravity of the moving parts is shifted to the lower horizontal guides, due to which they are skewed in the vertical plane and the accuracy of the alignment is reduced.

 The problem solved by the invention is to increase the accuracy of alignment of the moving parts by shifting the control elements in the horizontal direction directly to the lower horizontal guides.

 This problem is solved in that a horizontal hydraulic press comprising a front and rear cross member mounted on a bed, pulled together by columns through spacers, between which a movable cross member and a container holder are placed, mounted for movement in the upper and lower guides, adjustable in horizontal and vertical directions, and the lower ones are horizontal, the press is also equipped with vertical adjustable guides, and the upper ones are horizontal.

 In FIG. 1 of the drawing shows a longitudinal section of a horizontal press.

 In FIG. 2 shows the position of the container holder in the guides (section AA in FIG. 1).

 In FIG. 3 shows the position of the movable cross member in the guides (section BB in FIG. 1).

 Figure 4 shows the position of the matrix relative to the guides of the container holder and the movable cross member (section BB in Fig. 1).

 The horizontal hydraulic press comprises fixed crossbars mounted on the frame 1 front 2 and rear 3, pulled together through spacers 4 columns 5.

 Between the fixed cross members 2 and 3 there is a movable cross member 6 with a stamp 7, a container holder 8 with a container 9 and a slider 10 with a matrix 11. The movable cross member 6 is pressed onto the plunger of the working cylinder 12, and the container holder 8 moves from the cylinders 13.

 On the spacers 4, the lower horizontal guides 14, the lower vertical guides 15 and the upper horizontal guides 16 are rigidly fixed.

 The position of the movable cross member 6 and the container holder 8 relative to the upper and lower horizontal guides 16, 14, is regulated by the supports 17, and relative to the lower vertical guides - by the supports 18.

 All guides are machined to fit size E.

 To adjust the position of the axis of the matrix 11 there are wedges 19 and a stop 20.

 Alignment of the alignment of the container holder 8, the matrix 11 and the cross member 6 is performed in the following sequence.

 The movable cross member 6 with the stamp 7, moving along the guides 14, 15, is the basic part, against which the other moving parts of the press are aligned. The container holder 8 with the container 9 is set relative to the guides 14, 15 common with the movable cross member 6, and the landing dimension E is provided with the supports 17, 18 both in horizontal and vertical directions. The slider 10 with the matrix 11 is also set relative to the same guides 14, 15 with wedges 19 and a stop 20.
