Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to an angle cutting device for bending a steel pipe. Background Art

[0002] Steel pipe is a steel product with a circular cross-section, usually made of iron and steel, and sometimes other materials such as stainless steel or aluminum. Steel pipe is very common in many industrial and construction applications, such as oil and gas transportation, water treatment systems, building structure support, and various mechanical components. Steel pipes can have different wall thicknesses, diameters, and lengths according to manufacturing standards and usage requirements. During the construction or manufacturing process, steel pipes often need to be bent for installation or to form specific angles and shapes. Before bending the steel pipe, it is sometimes necessary to use a cutting device to cut the ends of the steel pipe.

[0003] During the processing of steel pipes, it is often necessary to cut corners at different positions to meet specific engineering requirements. Traditionally, this requires operators to manually measure at each cutting position and then move the steel pipe to the next predetermined cutting area. This method is time-consuming because it involves multiple repeated measurement and movement steps. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In order to solve the above problems of the prior art, the utility model provides a cutting angle device for steel pipe bending, which solves the problem that traditionally, this method requires operators to perform manual measurements at each cutting angle position and then move the steel pipe to the next predetermined cutting angle area. This method is time-consuming because it involves multiple repeated measurement and movement steps.

[0006] (II) Technical solution

[0007] In order to achieve the above purpose, the main technical solutions adopted by the utility model are:

[0008] A corner cutting device for bending steel pipes comprises a base plate, a support frame is connected to the base plate, a corner cutting assembly is arranged in the support frame, a processing table is connected in the support frame, two limit plates are connected to the processing table, a moving device is connected to one side of the processing table, a collecting device is connected in the support frame, the moving device comprises a stepping motor, a connecting plate is arranged on the outer sleeve of the stepping motor, a rotating plate is connected to the stepping motor, two fixed rotating wheels are overlapped on the outside of the rotating plate, and a connecting rod is connected under the fixed rotating wheel.

[0009] A bearing is connected under the connecting rod, and two sliding grooves are provided in the connecting plate. A slider is slidably connected in the sliding groove, and a movable plate is connected on the slider. Two movable wheels are rotatably connected to the movable plate, and a top plate is connected to the movable plate. A threaded rod is rotatably connected to the back side of the top plate, and a nut is connected to the external thread of the threaded rod.

[0010] The stepper motor is connected to one side of the support frame, and the bearing is connected to the connecting plate.

[0011] The connecting plate is connected to one side of the processing table, and the moving plate is overlapped on the connecting plate.

[0012] The nut is connected to the connecting plate, and the fixed rotating wheel corresponds to the movable rotating wheel in position.

[0013] The collecting device comprises a collecting box, which is installed in a supporting frame and is connected to a baffle.

[0014] The baffle plate corresponds to the position of the limiting plate, and an observation port is arranged in the collecting box.

[0015] (III) Beneficial effects

[0016] The beneficial effect of the utility model is that in the actual implementation process, when the steel pipe needs to be intermittently moved, the steel pipe is first clamped into the limit plate and the fixed rotating wheel and the movable rotating wheel, and then the threaded rod is rotated. After the threaded rod passes through the nut, a thrust is applied to the top plate, and the thrust drives the top plate and the movable plate to move. When the movable rotating wheel fixes the steel pipe outside the fixed rotating wheel, the stepper motor is started at this time, and the stepper motor drives the rotating plate to rotate. Then the rotating plate generates friction force on the fixed rotating wheel, and the friction force drives the fixed rotating wheel to rotate, and the fixed rotating wheel drives the connecting rod to rotate in the bearing. At this time, the fixed rotating wheel drives the steel pipe to move, and the steel pipe drives the movable wheel The driving wheel rotates, and the intermittent feeding of the steel pipe can be completed at this time. With the operation of the corner cutting component, the position of the steel pipe can be accurately moved after corner cutting. When cutting, the waste generated will generally be pushed out by the corner cutting component. At this time, the waste is pushed to the baffle, and then the waste falls into the collection box after passing the baffle. At this time, the intermittent feeding of the steel pipe and the collection of the waste are realized, avoiding the traditional need for operators to perform manual measurements at each corner cutting position and then move the steel pipe to the next predetermined corner cutting area. This method is more time-consuming because it involves multiple repeated measurement and movement steps. BRIEF DESCRIPTION OF THE DRAWINGS

In the actual implementation process, when the steel pipe needs to be intermittently moved, the steel pipe is first inserted into the limit plate 5 and the fixed rotating wheel 604 and the moving rotating wheel 610, and then the threaded rod 612 is rotated. The threaded rod 612 applies a thrust to the top plate 611 after passing through the nut 613, and the thrust drives the top plate 611 and the moving plate 609 to move. When the moving rotating wheel 610 fixes the steel pipe outside the fixed rotating wheel 604, the stepper motor 601 is started at this time, and the stepper motor 601 drives the rotating plate 603 to rotate, and then the rotating plate 603 generates a friction force on the fixed rotating wheel 604, and the friction force drives the fixed rotating wheel 6 04 rotates, the fixed wheel 604 drives the connecting rod 605 to rotate in the bearing 606, and the fixed wheel 604 drives the steel pipe to move, and the steel pipe drives the movable wheel 610 to rotate, and the intermittent feeding of the steel pipe can be completed at this time. With the operation of the cutting component 3, the position of the steel pipe can be accurately moved after cutting, avoiding the traditional need for the operator to perform manual measurement at each cutting position, and then move the steel pipe to the next predetermined cutting area.
