Example Embodiment

[0027] Example 1:

[0028] This embodiment provides a tool and die steel plate straightening machine, such as figure 1 with figure 2 As shown, including the main motor 10, it 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. The bracket is provided with a hollow movable beam 4, and the upper beam 2 is arranged symmetrically There are four hydraulic load cylinders 1, the piston rod of the hydraulic load cylinder 1 penetrates the upper beam 2 in the vertical direction and is rigidly connected with the movable beam 4, and the four hydraulic load cylinders 1 are arranged symmetrically with each other. The movable beam 4 is rigidly connected, which is beneficial to improve the stress condition of the frame.

[0029] Multiple sets of pressing mechanisms 5 are horizontally arranged on the upper part of the movable crossbeam 4, and the lower part of each pressing mechanism 5 is connected to a composite roller ...

Example Embodiment

[0033] Example 2:

[0034] In this embodiment, the pressing mechanism 5 is described in detail, such 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 passes 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 penetrates into the center of the worm wheel 21 in the vertical direction, and the lower end of the screw rod 22 is rigidly connected with the composite roller system 6.

[0035] Combine image 3 with Figure 4 The pressing mechanism 5 is used to adjust the up and down movement of the composite roller system 6. The structure in this embodiment is realized as follows: the worm 20 is rotated, and the worm 20 only rotates, and does not move in the axial direction. At this time, The matched worm wheel 21 starts to rotate in the horizontal direction. The center of the worm wheel ...

Example Embodiment

[0037] Example 3:

[0038] This embodiment further illustrates the composite roller system 6, such as Figure 5 As shown, the composite roller system 6 includes two vertically opposed side plates 15. The upper part of the two side plates 15 is fixed with an upper plate 16 transversely, and the lower part of the two side plates 15 is provided with an upper straightening roller 14 transversely. The middle part of the side plate 15 is horizontally movably equipped with a supporting roller bearing seat 17, so that the supporting roller bearing seat 17 moves up and down along the side plate 15, and the lower part of the supporting roller bearing seat 17 is equipped with an upper supporting roller 18;

[0039] A pre-tensioning inclined block 19 is installed between the supporting roller bearing seat 17 and the upper plate 16. The lower surface of the upper plate 16 and the upper surface of the pre-tensioning inclined block 19 are mutually parallel inclined surfaces. The upper surface of ...

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...
