Background technology
In recent years, along with the fast development of steel pipe clod wash industry, the technical equipment in industry is improved constantly, and each enterprise is in conjunction with the situation of self industry, and self-service research and development or Introduced From Abroad sophisticated equipment, to meet the process requirements of self product.
In the process preparing steel pipe, usual needs processing has the chapped pipe of space structure, if adopt, two steel pipes are linked together by certain space structure cloth postpone, in operating process like this, the relative position of steel pipe is difficult to ensure, also can other mode connections such as welding, riveted joint be adopted to there is connecting portion weakness because of connecting portion, easily reduction local strength be low simultaneously.
Especially when preparing bend pipe, the radian size of steel pipe curved arc section is formulated in meeting according to actual needs, such as produce the steel tubes of certain I-beam wheel, the curved arc degree size of its same steel pipe has 90o, 120o, enterprise is when preparing such a bend pipe, if introduce advanced steel tube bending equipment from external, for in, small enterprise's input cost is higher, so in majority, small enterprise selects to bend radian according to technician personal experience observe and decide steel pipe on prior art basis at home, but such operation can make the bend pipe processed there is the situation not meeting required precision because of the impact of individual subjective judgement, and then cause scrapping of steel pipe, thus increase the production cost of enterprise.
Summary of the invention
The object of the invention is the steel pipe parts in order to realize steel tube bending to become to preset radian size.
In order to achieve the above object, the present invention proposes the curved equipment of a kind of steel pipe system, comprise the operating desk being provided with slide rail, slide rail has can along the scroll chuck of slide rail movement, operating desk has and connects grip slipper by turning cylinder, turning cylinder is perpendicular to slide rail installed surface, grip slipper comprises stationary gripping part and clamping section, stationary gripping part there is pipeline roll forming periphery, clamping section can relatively rotate axle and move, pipeline gripping channel is formed between clamping section and stationary gripping part, clamping section regulates the size of gripping channel by screw rod, the bottom of clamping part is provided with angular stop means, angular stop means comprise angle scale and with angle scale edge be rotationally connected limited block, be provided with the block with limited block rotatable engagement rotating on contrary direction with steel pipe forming angle scale, clamping section is provided with turning handle.
The curved equipment of such scheme steel pipe system in use, being fixed on one end of steel pipe to be processed can along on the scroll chuck of slide rail movement, the other end is fixed between stationary gripping part and compressed part, rotate clamping part, clamping part with steel pipe rotate moving axis rotate, steel pipe with the periphery of turning cylinder for tube bending forming surface, angular stop means is provided with in the bottom of clamping part, angle scale there is circular scale, angle scale take operating desk as reference, the rotated to an angle fixed angle system of steel pipe of clamping part is curved, simultaneously in order to reduce the shakiness because of artificial range estimation regulation and control angle, be rotationally connected at angle scale edge limited block, be provided with the block with limited block rotatable engagement rotating on contrary direction with steel pipe forming angle scale, rotary spacing block, limited block is support with block, in angle scale rotation process, limited block and operating desk support and close, complete the fixing of the anglec of rotation, the scroll chuck steel pipe that scroll chuck moves clamping part is bending along slide rail in steel tube bending forming process carries out length compensation, scroll chuck can prevent rocking of steel pipe simultaneously, also clamping steel pipe can be regulated according to the external diameter of steel pipe, clamping section is provided with turning handle, utilize turning handle in steel pipe forming process, directly can rotate clamping part more laborsaving.
Further optimization, also comprise guiding holding block, guide holding block relative to stationary gripping part and described clamping section homonymy, and can be connected on described operating desk along slide rail side's upward sliding, holding block is guided to be regulated the resist force guided between holding block and workpiece by screw rod, can rotate along in turning cylinder tangential direction in tube bending forming process, cause the circular arc increased radius of tube bending, increase to reduce arc radius, arrange in side, clamping section and guide holding block to support steel pipe, prevent the distortion that steel pipe rotates along turning cylinder, guiding holding block part can along slide rail side's upward sliding, slide and reducing the slip sassafras that rubs and cause crooked position in the curved process of steel pipe system can not arrive the compensation of steel pipe timely, steel pipe is caused to occur pulling, affect the intensity in its follow-up use procedure, rigidity reduces, holding block is guided to be regulated the resist force guided between holding block and workpiece by screw rod, so resist force can be regulated, this kind of pretension adjusting device structure is simple simultaneously, easy to process, cost is with low cost relative to hydraulic clamp.
Further optimization, guide on holding block, stationary gripping part, clamping section and offer the circular arc camber coordinated with steel pipe periphery to be processed, circular arc camber can hold a part of steel pipe, reducing in the curved process of steel pipe system causes local steel pipe to be crushed because of the gap sudden change of brake forming, circular arc camber also has the guiding function to steel pipe simultaneously, prevents steel pipe in the skew of making in curved process and rocks.
Further optimization, comprises rule, and rule is fixed along on slide rail direction, according to the relative length of the energetic every section of bending of rule.
