Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a die for stamping a plate rib includes:

a stamping die;

a tractor 1 arranged behind the stamping die;

the plate rib flattening device is arranged in front of the stamping die;

when the plate rib flattening device works, the plate rib 2 is pulled by the tractor 1, so that the plate rib 2 sequentially passes through the plate rib flattening device and the stamping die.

The working principle is as follows: by arranging the plate rib flattening device, the plate rib 2 can be flattened by the plate rib flattening device before being stamped, and the metal plate before being stamped is ensured to be flat; simultaneously add tractor 1, utilize tractor 1 to pull the lath 2 and go forward, saved the process of artifical placing, avoid the staff to be accidentally injured by stamping die, improved production efficiency.

The stamping die includes:

the upper die 3 is detachably and fixedly connected with a piston rod of an external press machine;

the lower die 4 and the lower die 4 are detachably and fixedly connected with a workbench of an external press machine.

The plate rib flattening device comprises:

The lower roller body comprises:

the lower roller seat 7 is fixedly connected with the external frame;

and the lower roller 8 is in running fit with the lower roller seat 7 through lower roller shafts at two ends of the lower roller 8.

The upper roll body includes:

an upper roller body base 13;

an upper roller 12, the upper roller 12 is rotatably matched with the upper roller body seat 13 through upper roller shafts at two ends of the upper roller.

The guide device includes:

the bottom of the cylinder body of the hydraulic cylinder 10 is fixedly connected with the lower roller body seat 7, and the number of the hydraulic cylinders 10 is four, and the four hydraulic cylinders are respectively positioned at four corners of the lower roller body seat 7;

and a non-through guide hole 11 is formed in the lower end of the upper roller body seat 13, and the guide hole 11 is in sliding fit with a piston rod of the hydraulic cylinder 10.

Specifically, the four hydraulic cylinders 10 are respectively arranged at two sides of the plate rib 2, and two hydraulic cylinders 10 are arranged at each side, so that the supporting function of the hydraulic cylinders 10 can be ensured, the hydraulic cylinders do not interfere with the plate rib 2 in the working process, and the normal movement of the plate rib 2 is ensured; the ascending and descending of the upper roller body can be controlled by controlling the piston rod of the hydraulic cylinder 10, so that the purpose of adjusting the distance between the upper roller 12 and the lower roller 8 is achieved, an operator can conveniently penetrate the plate rib 2 through the gap between the upper roller 12 and the lower roller 8, and after the distance between the upper roller 12 and the lower roller 8 is adjusted, the piston rod of the hydraulic cylinder 10 falls back, so that the piston rod is separated from the bottom of the guide hole 11; tractor 1 pulls lath 2 to remove, and the lath 2 before making the punching press passes through between last roller 12 and lower roller 8, goes up roller 12 and lower roller 8 and rotates along with it, utilizes the cooperation of going up roller 12 and lower roller 8 to rotate and accomplishes the leveling work to lath 2, guarantees the roughness of the lath before being punched, has guaranteed the quality of punching press product. Go up roller 12 through the last roller shaft at its both ends with go up roller body seat 13 normal running fit, lower roller 8 is through the lower roller shaft at its both ends and lower roller body seat 7 normal running fit, and the lath 2 that is pulled like this is levelled and smooth by the pivoted roller, has just also avoided lath 2 to be producing the mar by the leveling process, further assurance the quality of product.

The plate rib flattening device further comprises an extension spring 9, and two ends of the extension spring 9 are respectively connected with the end parts of the upper roll shaft and the lower roll shaft in a hanging mode.

Specifically, by providing the extension spring 9, the pressing force of the upper roller 12 and the lower roller 8 on the plate rib 2 can be further increased, and the flatness of the plate rib 2 is ensured.

Still include strutting arrangement, strutting arrangement includes:
