Abstract
The utility model belongs to a longitudinal shearing device for welded pipe blank, which is particularly suitable for longitudinal shearing of short narrow strip steel which is a blank for producing welded pipes. The device comprises a transmission mechanism, a strip steel leveling and correcting mechanism, a micro-elastic roller type guide mechanism and a shearing mechanism. The cutting edge is trapezoidal. The wavy plate surface bending after the strip steel is uncoiled can be eliminated, and the biting capability of the shearing mechanism is increased. The guide and guard position can be automatically adjusted within the width tolerance range of the strip steel in the shearing process, the strip steel can be ensured not to deviate, the phenomena of edge sliding damage, edge warping, oblique shearing and the like can be avoided, and the shearing quality can be greatly improved. The edge shearing can not be removed by using a single pair of scissors for shearing, and the yield is improved.
Description
The utility model belongs to welded tube blank longitudinal shear equipment, and it is specially adapted to producing the blank of welded tube---and short ribbon steel carries out slitting.
It is the preceding working procedure that welded tube is produced that the skelp material is carried out slitting.At present, welded tube factory generally adopts rolling twice welded tube blank width then through side cut slitting welded tube blank when to produce diameter be welded tube below 25 millimeters with short ribbon steel.The slitter that uses mainly partly is made up of known running part, cutting out section (many to scissors) and sliding guide at present, and this slitter exists following defective:
1, can not eliminate the waveform plate face bending that the band steel occurs after uncoiling, thereby in the slitting process, easily cause and cut defectives such as inclined to one side.
2, guide and guard mechanism is the fixed slideway, and variation that can not steel width tolerance going along with in shear history and follow-up adjustment, and be sliding friction between band steel and slideway often with strip edge edge sliding injury, cause the weld bond misrun and the eye of leakage is arranged.
3, the cutting edge of existing slitter is the straight snips sword, and cutting edge is arranged as in the same way and arranges, make the band steel in shear history, after being subjected to the shear pressure effect to cause cutting, the alice phenomenon occur, use this blank to produce welded tube, postwelding a facet phenomenon will occur at welded tube weld bond edge, thereby directly have influence on the product quality of welded tube.If utilize this slitter slitting (promptly removing the two pairs of scissors in two ends) of not cutting edge, also can make the band steel in shear history, be subjected to the shear pressure effect, and the band steel is twisted, to be with steel to cut tiltedly, it is overproof to make the band steel cut the back width, and weld seam lacks muscle after causing moulding, and does not reach the welding tube quality standard.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of welded tube blank slitting device is provided.
The purpose of this utility model is achieved by the following scheme: comprise in the composition of welded tube blank slitting device that transmission mechanism (1) belt steel flating straightening mechanism (2) guide and guard mechanism (3) and cutting mechanism (4) belt steel flating straightening mechanism be made up of upper and lower two principal and subordinate's rollers, 1. transmission mechanism drives drive roll and rotates, and driven voller rotates with drive roll.Guide and guard mechanism is micro-elasticity roll-type guide and guard mechanisms, 2. it link to each other with smooth straightening mechanism, the upper strata of this mechanism is made up of Roll Collar (5) Roll Collar frame (6) and adjustment guide and guard framves (7), between Roll Collar frame (6) and the adjustment guide and guard framves (7) the micro-elasticity body is housed, lower floor links to each other with guide and guard mechanism for adjusting guide and guard frame bases (8) cutting mechanism, the cutting edge of shear blade in the cutting mechanism (9) be "
" shape; the plane that the great circle external diameter that utilizes shear blade and the roundlet external diameter of pairing shear blade are formed; the strip edge edge of shearing is pushed, eliminate and cut back alice phenomenon, this shear blade can also be by self stressed band steel shearing torsion phenomenon of eliminating in shear history.
Use the utility model that short ribbon steel is carried out slitting, can eliminate the wave plate face bending that after the uncoiling of band steel, occurs, increase the ability of nipping of cutting mechanism, the guide and guard position can be adjusted in the strip width margin of tolerance automatically in the shear history, and can guarantee not sideslip of band steel, edge sliding injury, alice can not take place, cut phenomenons such as oblique, thereby can improve shearing quality greatly.In addition, use list of the present utility model that scissors is sheared not remove and cut the limit, improve the welded tube lumber recovery.
Accompanying drawing is the structural representation of an embodiment of the utility model.
Below with reference to accompanying drawings, further specify the utility model by embodiment.
The utility model adopts the known kind of drive (motor, reductor, divide axial organ) import as power, after the uncoiling of band steel, at first enter belt steel flating straightening mechanism (2), this mechanism is by last, following two rollers are formed, two rollers are located with same bearing block (10) supporting, lower roll is a drive roll, power is imported from left end, top roll is a driven voller, last roll shaft is fixed in the slideway of bearing, the rectification pressure of smooth straightening mechanism presses the adjustment leading screw of installing on the beam (11) to regulate by adjusting bearing block (10) slideway, in bearing block slideway bottom, has rubber elastomer (12) to come roll shaft on the balanced support.Micro-elasticity roll-type guide and guard mechanism links to each other with the belt steel flating straightening mechanism, this mechanism is by upper and lower two-layer the composition, the upper strata is made up of two pairs of Roll Collars (5), Roll Collar frame (6) and adjustment guide and guard framves (7), between Roll Collar frame (6) and adjustment guide and guard framves (7), micro-elasticity body---spring is housed, its elasticity can be regulated by adjusting locknut (13), lower floor is for adjusting guide and guard frame bases (8), two adjustment leading screws are housed in the base, adjust the position of left and right Roll Collar (5) by handwheel (14), to guarantee to adapt to various products.The part that links to each other with the guide and guard mechanism other end is a cutting mechanism, shearing in the middle of the memorial archway frame (15), by two pairs of bearing blocks (16), is supporting two shearing cutter shafts of upper and lower layout, be installed with respectively on two shearing cutter shafts cutting edge for "
" shear blade (9) of shape, in cutter shaft cutting edge both sides down, the micro-elasticity of being made up of foreplate dish and micro-elasticity body (butterfly spring) to be housed defend plate dish (17), its can steel wide variety going along with and adjust the position automatically, the assurance shearing quality.Be provided with spring equalizing device (18) between the upper and lower diaxon bearing with cutter shaft on the balanced support, the sideshake adjustment of cutting edge is to finish by being fixed on the adjustment bolt (19) of shearing the memorial archway outside.Shearing memorial archway frame (15) top, be equipped with and adjust leading screw (20), so that adjust the size of cutting edge lap according to product thickness.Between smooth straightening mechanism and cutting mechanism, a horizontal guide and guard flat board (21) is housed, successfully nip to guarantee the band steel.
