The lower roller seat of the plate bending machine is one of key parts of the plate bending machine. Because the steel casting blank bears a large acting force in the using process, the stress condition is complex, the space is narrow, and the steel casting blank is always used. However, with the increasing importance of the country on the environmental protection work, high-energy-consumption and high-pollution enterprises are gradually shut down, and small-scale casting enterprises are less and less. The large-scale plate rolling machine belongs to high, large, precise and sharp equipment, so that the production batch is very small and almost all single-piece production is determined, and the large-scale plate rolling machine cannot meet the requirement of large product batch of large-scale casting enterprises, so that embarrassment is required to be solved urgently.
Disclosure of Invention
The utility model aims at solving the above problem, providing a large-scale veneer reeling machine welding type lower roll seat, adopt welded structure, suitable batch production, the low energy consumption, the low pollution.
According to the technical scheme of the utility model, the welding type lower roller seat of the large-scale plate rolling machine comprises two side plates which are arranged in parallel, wherein grooves are arranged at two ends of the upper side edges of the side plates, and lower roller sleeves are arranged in the grooves; a worm wheel shaft sleeve is arranged between the two ends of the lower side of the side plate, an upper vertical plate is arranged above the worm wheel shaft sleeve, a lower vertical plate is arranged below the worm wheel shaft sleeve, arc-shaped grooves matched with the worm wheel shaft sleeve are formed in the lower side edge of the upper vertical plate and the upper side edge of the lower vertical plate, and the arc-shaped grooves are attached to the outer wall of the worm wheel shaft sleeve; an inner vertical plate is arranged between the middle parts of the side plates, and a semicircular groove concentric with the inner hole of the worm wheel shaft sleeve is formed in the lower side edge of the inner vertical plate.
Furthermore, the upper vertical plate and the lower vertical plate are arranged at the outer end part of the worm wheel shaft sleeve.
Furthermore, the upper vertical plate and the lower vertical plate are located on the same plane.
Furthermore, a middle vertical plate is arranged between the side plates and attached to the inner end face of the worm gear shaft sleeve, and a hole is formed in the middle vertical plate corresponding to the inner hole of the worm gear shaft sleeve.
Furthermore, the upper end sideline of the middle vertical plate is tangent to the excircle of the lower roller sleeve.
Furthermore, the inner vertical plates are arranged side by side.
The beneficial effects of the utility model reside in that: the machining process has the advantages that after a casting is changed into a welding part, a steel plate can be cut by a numerical control cutting machine, steel pipes can be blanked, a casting wood mold does not need to be manufactured, the manufacturing period is shortened, the production cost is reduced, and the method is more suitable for small-batch and single-piece production; the structure is simple, the stability is high, and the complex stress conditions of positive pressure, lateral pressure, horizontal thrust, vertical bending, horizontal torsion and the like can be met; the requirement on the high-pollution small casting industry is reduced, the environment is protected, and the method is more suitable for the current industry.

Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: a welding type lower roller seat of a large-scale plate bending machine comprises two side plates 1 which are arranged in parallel. The both ends of curb plate 1 upper side limit are equipped with the recess, install lower roll shell 2 in the recess. A worm wheel shaft sleeve 3 is arranged between two ends of the lower side of the side plate 1, an upper vertical plate 5 is arranged above the worm wheel shaft sleeve 3, a lower vertical plate 4 is arranged below the worm wheel shaft sleeve 3, arc-shaped grooves matched with the worm wheel shaft sleeve 3 are formed in the lower side edge of the upper vertical plate 5 and the upper side edge of the lower vertical plate 4, and the arc-shaped grooves are attached to the outer wall of the worm wheel shaft sleeve 3. An inner vertical plate 7 is arranged between the middle parts of the side plates 1, and a semicircular groove concentric with the inner hole of the worm-gear shaft sleeve 3 is formed in the lower side edge of the inner vertical plate 7.
Specifically, in order to fully meet the stress requirement, the upper vertical plate 5 and the lower vertical plate 4 are arranged at the outer end part of the worm wheel shaft sleeve 3, and the upper vertical plate 5 and the lower vertical plate 4 are positioned on the same plane; a middle vertical plate 6 is arranged between the side plates 1, the two middle vertical plates 6 are respectively positioned at two sides of the inner plate 7, the outer side surface of the middle vertical plate 6 is attached to the inner end surface of the worm wheel shaft sleeve 3, and a hole is formed in the middle vertical plate 6 corresponding to the position of the inner hole of the worm wheel shaft sleeve 3; the upper end sideline of the middle vertical plate 6 is tangent with the excircle of the lower roller sleeve 2; the inner vertical plates 7 are arranged side by side.
