Embodiment 1

[0028] This embodiment provides a tool and die steel plate straightening machine, such as figure 1 and figure 2 As shown, it includes the main motor 10, and also includes a bracket composed of an upper beam 2, a lower beam 9, and four pillars passing through the four corners of the two. A hollow movable beam 4 is arranged in the bracket, and the upper beam 2 is symmetrically arranged in four directions. There are four hydraulic load cylinders 1, the piston rod of hydraulic load cylinder 1 runs through the upper beam 2 in the vertical direction of the upper beam 2 and is rigidly connected with the movable beam 4, and the four hydraulic load cylinders 1 are symmetrically arranged in a square, and their piston rods and The movable crossbeam 4 is rigidly connected, which is conducive to improving the stress condition of the frame.

[0029] There are multiple sets of pressing mechanisms 5 horizontally arranged above the movable beam 4, and the bottom of each pressing mechanism 5 ...

Embodiment 2

[0034] In this embodiment, the depressing mechanism 5 is described in detail, as Figure 4 As shown, the pressing mechanism 5 includes a worm 20, a worm wheel 21 with a nut in the center, and a screw 22. The worm 20 traverses through the beam wall of the movable beam 4 and is installed in cooperation with the worm wheel 21. The worm wheel 21 is arranged horizontally, and the screw 22 The nut that penetrates the center of the worm wheel 21 along the vertical direction, and the lower end of the screw mandrel 22 is rigidly connected with the composite roller system 6 .

[0035] combine image 3 and Figure 4 , the depressing mechanism 5 is used to adjust the up and down movement of the compound roller system 6. This structure in the present embodiment is realized according to the following process: the worm screw 20 is rotated, and the worm screw 20 only rotates and does not move in the axial direction. At this time, The worm wheel 21 matched with it starts to rotate in the hor...

Embodiment 3

[0038] In this embodiment, the compound roll system 6 is further described, as Figure 5 As shown, the composite roll system 6 includes two side plates 15 vertically opposite to each other. An upper plate 16 is fixed horizontally on the upper parts of the two side plates 15, and an upper straightening roller 14 is installed on the lower parts of the two side plates 15 horizontally. The middle part of the side plate 15 is horizontally equipped with a backup roller bearing seat 17, so that the backup roller bearing seat 17 moves up and down along the side plate 15, and the lower part of the backup roller bearing seat 17 is equipped with an upper backup roller 18;

[0039] A pre-tightening inclined block 19 is installed between the back-up roller bearing seat 17 and the upper plate 16. The lower surface of the upper plate 16 and the upper surface of the pre-tightening inclined block 19 are inclined surfaces parallel to each other. The upper surface of the back-up roller bearing se...

Abstract

The invention belongs to the technical field of metallurgical equipment, in particular to a tool-die steel plate straightening machine. A classic three-beam four-column prestress rack is used, and a roller system with four rollers at the top and five rollers at the bottom is arranged. Opening degrees of the four straightening rollers at the top can all be adjusted independently, all the top straightening rollers are provided with independent support rollers, and each top straightening roller and the corresponding support roller form an independent compound roller system to perform adjustment. Hydraulic load cylinders are arranged above an upper beam, a movable beam can be lifted rapidly while overload protection is achieved, and accordingly maintenance can be performed conveniently. According to the tool-die steel plate straightening machine, because the opening degrees of all the top straightening rollers can be adjusted independently, the opening degrees can be adjusted flexibly from small to large according to original bends, thickness, width and materials of plates, the rolling reduction of the top straightening rollers is changed from large to small, straightening accuracy is improved, and meanwhile the one-step forming rate of the plates is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and is particularly applied to the field of medium and thick plate straightening, in particular to a tool and die steel plate straightening machine. Background technique [0002] Existing high-strength tool steel sheet straightening machine, because straightening force is big, work roll must be equipped with back-up roll. [0003] In terms of the adjustment of the roll gap opening, many models adopt the overall pressing scheme, which has a simple structure and good strength, but the number of straightening rollers must be large to effectively ensure the one-time forming rate of the sheet. [0004] There are also some models that adopt the scheme of the overall inclination of the upper roller system, so that the opening of the straightening rollers gradually increases, so as to achieve the effect of improving the one-time forming rate of the plate and improving the straightening ac...
