Description

Technical Field

[0001] This article belongs to the technical field of bend pipe punching tooling, and specifically relates to a convenient and efficient bend pipe outer surface punching tooling. Background Art

[0002] The pipe bend is made by using a set of bending dies, which is divided into two processes: cold bending and hot pushing. Regardless of the type of machinery and equipment and pipelines, most of them use pipe bends, which are mainly used for oil, gas, and liquid transportation. At the same time, the shapes of the pipe bends are different. At the same time, right-angle pipe bends are more frequent in daily use, and the pipe bends need to be punched during production. When traditional punching machines are used to limit the punching of right-angle pipes, most of them use clamps to limit the right-angle pipes. The overall limit stability is poor, and the overall limit operation is complicated and has large overall limitations.

[0003] Currently, when drilling holes in bent pipes, the hole locations are typically marked on the pipe itself, and then the marked pipe is taken to a drill rig for drilling. This method is time-consuming and labor-intensive, resulting in low efficiency; manual marking also introduces certain errors. Because the curved surface cannot accurately position the holes, skewed holes are often created, impacting subsequent use of the bent pipe. If the holes are drilled first and then bent, the tensile forces during the bending process can alter the hole's position, size, and shape. Utility Model Content

[0004] In order to solve the above problems, this paper proposes a convenient and efficient tool for punching holes on the outer surface of a bent pipe. The punching tool is fixedly arranged on the upper surface of the drilling machine table through a tool base. The punching tool includes a horizontal rotation component, a longitudinal rotation component and a pipe clamp. The horizontal rotation component includes a horizontal rotation seat, a manual reducer and a bearing seat. The longitudinal rotation component includes a longitudinal rotation seat, a servo motor and an extension bracket. The bottom of the horizontal rotation seat is symmetrically connected to the bearing seat axially. The outer end of the bearing seat on one side is provided with a manual reducer. The horizontal rotation seat is axially connected to the manual reducer through the bearing seat. The rear side of the horizontal rotation seat is provided with a servo motor. The servo motor is provided with a drive gear running through the inside of the horizontal rotation seat. The upper end face of the horizontal rotation seat is arc-shaped. It is connected to the bottom slide of the longitudinal rotating seat in a sliding manner, and the middle part of the bottom surface of the longitudinal rotating seat is meshed with the driving gear through an arc-shaped rack. The inner middle part of the longitudinal rotating seat is protruding toward the front and is provided with an extension bracket. The outer upper surface of the extension bracket is provided with a pipe clamp, and the upper surface of the pipe clamp is provided with a plurality of horizontally parallel arc pipes in a card-connected manner. By setting the punching tooling with two horizontal and vertical rotation adjustment degrees of freedom, it is possible to realize fast manual front and rear horizontal axis flipping positioning to determine the position of the arc pipe to be punched, and then the left and right longitudinal axis rotation controlled by the servo motor is used to accurately position the hole spacing of each hole, so that the arc tube punching that originally required high difficulty can be conveniently realized by direct tooling adjustment punching, thereby reducing the manual learning cost, improving the punching accuracy, and ensuring the punching efficiency.

[0005] The tooling base is in the shape of an arm-type tooling base, which includes a suspended support arm and a base plate. Suspended support arms are protruding from the front on both sides of the bottom surface of the base plate. The bottom surface of the suspended support arm is connected to the upper surface of the drilling machine table. An avoidance gap is provided between the front ends of the suspended support arms on both sides. Through the tooling base with a suspended support arm, an avoidance gap is provided on the front side of the tooling base, so that the extended bracket that rotates the longitudinal axis can be easily avoided at the lower end to prevent interference.

[0006] The bearing seat is symmetrically arranged on the upper surface of the tooling base, and a limiting guide groove is provided on the outer side of the axis of the surface of the bearing seat. A transverse rotating seat is provided between the symmetrical bearing seats for axial rotation, and a manual reducer is provided adjacent to the outer side of the bearing seat on the left. The transverse rotating seat is embedded between the symmetrical bearing seats, and the rotating shaft of the transverse rotating seat is connected to the manual reducer. The two side surfaces of the transverse rotating seat are connected to the limiting guide grooves of the bearing seat through guide columns. The bearing seat with a limiting guide groove can ensure the amplitude of the transverse rotating seat during the rotation process, and prevent the rotation angle from being too large and causing interference and collision with other components, thereby causing damage. The bearing seat is also adjacent to the manual reducer, which is convenient for manual and rapid adjustment of the transverse rotating seat to a small angle.

[0007] The shell seat of the horizontal rotating seat is hollow, and the upper end surface of the horizontal rotating seat is horizontally provided with an arc guide groove, and the left and right ends of the bottom of the horizontal rotating seat are horizontally provided with shafts, and the interior of the horizontal rotating seat is horizontally provided with a driving gear, and a servo motor is provided at the middle part of the rear side of the horizontal rotating seat. The arc guide groove is slidably connected to the longitudinal rotating seat, and the rotating shaft of the servo motor passes through the horizontal rotating seat and is connected to the driving gear. The horizontal axial manual rotation is realized through the lower end of the horizontal rotating seat, and the upper end of the horizontal rotating seat performs longitudinal rotation of the longitudinal rotating seat in the form of an arc guide groove. The arrangement of the driving gear inside the horizontal rotating seat can conveniently and concealedly drive the longitudinal rotating seat.

[0008] The longitudinal rotating seat is in the shape of a semicircular arc-shaped shell seat, and an extension bracket is fixedly provided in the middle of the inner side of the longitudinal rotating seat. The shape of the extension bracket is a vertically parallel Z-shaped bracket, and the upper surface of the extension bracket is provided with a number of ribs longitudinally parallel to each other. The surface of the extension bracket and the surface of the ribs are provided with a number of weight-reducing openings. The bottom surface of the upper folded end of the extension bracket is fixedly overlapped and arranged at the inner center of the longitudinal rotating seat, and the top surface of the lower broken end of the extension bracket is clamped with a pipe clamp. The longitudinal rotating seat realizes left and right longitudinal swinging through an arc-shaped rack, so that the extension bracket arranged thereon can also be rotated left and right, thereby realizing precise adjustment of the required position of the vertical drilling machine drill bit, and the practical servo motor can ensure high-precision position adjustment.

[0009] The pipe clamp is in the shape of an arc-shaped clamp block. The bottom surface of the pipe clamp is horizontally connected to the extension bracket by clamping. The curvature of the arc surface of the upper surface of the pipe clamp is the same as the curvature of the arc-shaped pipe. The upper surface of the pipe clamp is horizontally parallel to a plurality of pipe slots. The pipe slots are downward-pressed slots with openings on the left, right and top sides. The plurality of pipe slots are raised equidistantly from front to back. The pipe clamp can realize the convenient and rapid clamping connection of the required arc-shaped pipe, and is also connected to the extension bracket by clamping, thereby completing the replacement of different curvatures. The pipe clamp is driven by the horizontal rotating seat and the longitudinal rotating seat to perform flexible rotation with two degrees of freedom, thereby realizing precise control of the position of the outer surface of the arc-shaped pipe for the required drilling hole on the surface of the pipe clamp.

[0010] Beneficial effects:

[0011] By setting the punching tooling with two degrees of rotation and adjustment freedom, the front and rear lateral axis can be quickly and manually flipped to determine the position of the arc pipe to be punched. The left and right longitudinal axis rotation controlled by the servo motor can then be used to accurately position the hole spacing of each hole. This makes it convenient to achieve direct tooling adjustment and punching, which originally required high-difficulty arc pipe punching. This reduces the manual learning cost, improves the punching accuracy, and ensures the punching efficiency.

[0012] Through the tooling base with a suspended support arm, an avoidance gap is set on the front side of the tooling base, so that the extension bracket rotated by the longitudinal axis can be easily avoided at the lower end to prevent interference.

[0013] The bearing seat with a limited guide groove can ensure the amplitude of the lateral rotating seat during the rotation process, preventing interference and collision with other components due to excessive rotation angle, which may cause damage. The bearing seat is also adjacent to the manual reducer, which facilitates manual and rapid adjustment of the lateral rotating seat at a small angle.

[0014] The longitudinal rotating seat realizes left and right longitudinal swing through the arc-shaped rack, so that the extension bracket set on it can also rotate left and right, thereby realizing the precise adjustment of the required position of the vertical drilling machine drill bit, and the practical servo motor can ensure high-precision position adjustment.

[0015] The pipe clamp can be used to quickly and easily connect the required curved pipes, and can also be connected to the extension bracket by clamping, so as to complete the replacement of different curvatures. The pipe clamp is driven by the horizontal rotating seat and the longitudinal rotating seat to flexibly rotate in two degrees of freedom, so as to achieve precise control of the outer surface position of the curved pipe where the required drilling hole is located on the surface of the pipe clamp.
