Abstract

The utility model relates to a deviation adjusting mechanism which can improve the diagonal precision of a cross shearing unit product. A sliding base walking frame with liner guide tracks is installed between two groups of reference blocks and reference catch wheels and between movable blocks and movable catch wheels in front of a plate shearing machine; an upper feed roller and a lower feed roller are installed on the walking frame; and air cylinders are installed on one side of the movable block and the two sides of the sliding base walking frame. As the feed roller is date pit shaped, sheet material in feeding can be stably closed to a reference datum with the pushing of the air cylinders, the radial position of the sheet material can be determined, and the diagonal precision of the cross shearing unit product can be improved.

Description

Crosscut unit adjusting deviation device

Affiliated technical field

The utility model belongs to the metal coiled material manufacture field, relates to a kind of crosscut unit adjusting deviation device.

Background technology

At present, coiled strip crosscut unit is difficult to realize control to the diagonal of product.Known crosscut production line is in order to solve the diagonal requirement of product, two groups of parallel shelves wheels generally are installed in the both sides of feeding roller, these grades wheel must leave the gap of 2 millimeter with plate, because metal material has higher intensity, run into maximum the moment of inertia when thruster sheet material, add the powerful clamping of a pair of feeding roller, plate is on shear line, radial displacement is uncontrollable, and deviation phenomenon seriously takes place.

Summary of the invention

For overcoming the deficiency of plate uncontrollable position on production line, the utility model provides a cover crosscut unit adjusting deviation device, and it can stablize the radial position of control plate before shearing, improves the diagonal precision of product.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of crosscut unit adjusting deviation device, reference block and benchmark shelves wheel divide two groups, and movable block and movable shelves wheel divide two groups, and the centre is a pair of feeding roller up and down, and feeding roller is contained on the capable frame of a straight line guide rail slide up and down, and the installation direction of guide rail is vertical with the feed direction of sheet material.

On described movable block and the capable frame of guide rail slide cylinder is installed; The feed direction of cylinder moving direction and plate is vertical.In the described feeding roller up and down, have at least one to be date core shaped.Wherein, on the capable frame of guide rail slide a pair of cylinder is arranged, can lift going up feeding roller, making up and down, feeding roller breaks away from.

Gear wheel on described reference block and the movable block is for adapting to the plate washer of thin plate tuningout demand.

Plate by crosscut before, a side of plate should be close to a datum level, for this reason, the plate in the conveying, must be able to realize lateral displacement and center the rotation.4 groups of shelves wheels are set on the front and back position of feeding roller, and a side is a true edge, and a side is an active edges.In the middle of feeding roller was arranged on, having one in two feeding rollers at least was date core shaped, and it forms point with plate and contacts.A pair of feeding roller is installed on the capable frame of cross slide way slide, under the capable frame of slide slide rail is housed, and can do radial motion.The movable block of capable frame of slide and both sides is equipped with cylinder.When plate will reach clipped position under the clamping of numerical-control feed roller, a side cylinder relative with datum level began to promote, and plate is pushed to true edge one side, to realize the coincidence fully of plate and datum level.

The utility model has easy effect to be:

Before coiled strip crosscut unit is sheared, adjust the clipped position of plate, improve the diagonal precision of product, and simple in structure, cost is low.

Among the figure: 1. the benchmark shelves are taken turns (two groups), 2. reference block (two groups), 3. feeding roller right cylinder, 4. movable shelves wheels (two groups), 5. movable block (two groups), 6. movable block cylinder (two groups), 7. feeding roller left hand cylinder, 8. support roller, 9. line slideway, the 10. capable frame of guide rail slide, 11. last feeding roller, 12. times feeding rollers, 13. top roll lifting arms, 14. top roll promotes cylinder, 15. plates, 16. AC servo motors, 17. the flute profile band, 18. plate shearing machines, the edge of a knife about in the of 19..

Below in conjunction with accompanying drawing and specific embodiment of the utility model the utility model is further described:

Specific implementation method

At Fig. 1-1, in Fig. 1-2, two groups of benchmark shelves wheel 1 is contained in the top of two groups of reference blocks 2, requires to adjust to the accurate position vertical with the edge of a knife up and down 19 of plate shearing machine 18 in debugging, and locking.Feeding roller right cylinder 3 and feeding roller left hand cylinder 7 are contained on the capable frame 10 of guide rail slide, when cylinder moving, just can promote the capable frame of guide rail slide and 11 times feeding rollers of last feeding roller, the 12 clamping plates 15 that are installed on it move together; AC servo motor 16 is realized the length location of plate by flute profile band 17.Among Fig. 1, the direction of arrow is the feed direction of plate, and support roller 8 is the support roller of plate 15.When plate 15 began feeding under the clamping of up-down rollers, certain interval L was left in the left and right sides, to reduce the friction of shelves wheel and plate, improved feeding speed.This structure is like this work: at initial phase (can be that plate shearing machine is finished the last back of shearing), movable block cylinder 6) drive piece 5 and movable shelves wheel 4 resets to the left side; Top roll promotes cylinder 14 and drives top roll lifting arm 13 and go up feeding roller 12) lift, feeding roller and plate (15) are disengaged; Under the promotion of feeding roller right cylinder 3, make the capable frame 10 of guide rail slide on the line slideway 9 drive up-down rollers move to left put in place after, top roll promotes cylinder 14 top roll is put down, up-down rollers is clamping plate 15 again, at this moment, between benchmark shelves wheel and the plate, have a gap L between movable shelves wheel and the plate, so far finish initialization.Begin to carry plate, AC servo motor 16 drives flute profile band 17 and drives the up-down rollers feeding, when near final size, feeding roller left hand cylinder 7 reaches movable block cylinder 6 and moves simultaneously, and plate is shifted onto on the true edge, when AC servo motor arrival clipped position, plate shearing machine is finished once and is sheared.

Working state schematic representation after Fig. 2 steps up for the utility model crosscut unit adjusting deviation device gets cylinder.

Fig. 3 is second embodiment of the present utility model, and benchmark shelves wheel and movable shelves wheel change benchmark plate washer and movable plate washer into, when preventing to promote than thin material, and sheet metal deformation.
