Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to an array punching device for flange processing. Background Technique

[0002] A flange, also known as a flange plate or flange, is a part used for connecting shafts to each other and is used for connecting pipe ends; flange holes are round holes opened at the flange edge and are distributed in a circumferential array, which are used for installing bolt fasteners to realize the fastening of two flanges; the number of flange holes varies according to the size of the flange, and common flanges have different specifications such as four holes, six holes, and twelve holes;

[0003] In the prior art, for the array punching device used for flange processing, the distribution of its punching components is relatively fixed, and it can only produce flanges with a fixed number of holes. When it is necessary to produce flanges with other hole number specifications, the equipment or assembly needs to be replaced, and the operation is relatively troublesome; and during punching, there is a lack of effective fixing and positioning effects, the accuracy of the punching position cannot be guaranteed, and the punching position cannot be adjusted. For this reason, we propose an array punching device for flange processing. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an array punching device for flange processing, which has a reliable array punching unit. Twelve mounting boxes distributed in a circumferential array can provide three different punching specifications of four holes, six holes, and twelve holes. Through the control console, the corresponding number of punching holes can be selected, and the punching laser heads at the corresponding positions can be controlled to realize array punching operations; and under the push of the electric push rod, the slider can drive the punching laser head to move along the radius direction of the fitting cover plate to adjust the punching position; it also has a reliable placement and positioning unit, which can support and fix the flange workpiece to be processed and center it to ensure the accuracy of the subsequent punching position, and can effectively solve the problems in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: An array punching device for flange processing, comprising a mounting frame, a placement and positioning unit, and an array punching unit;

[0006] The mounting frame: has an L-shaped structure and is fixedly connected with a horizontal top plate at the upper end;

[0007] The placement and positioning unit: is installed between the mounting frame and the top plate;

[0008] Array punching unit: It includes an installation box, a control console, installation sliding rods, sliders, punching laser heads, and electric push rods. The placement and positioning unit includes a fitting cover plate. The fitting cover plate is horizontally arranged between the installation frame and the top plate. Twelve rectangular installation boxes are fixedly connected in a circumferential array at the upper end of the fitting cover plate. Each installation box faces the center of the fitting cover plate. A notch communicating with the inside of the installation box is opened on the end face of the fitting cover plate. Two horizontal installation sliding rods are fixedly connected inside each fitting cover plate. The sliders are arranged inside the installation boxes. The installation sliding rods pass through the inside of the sliders, and the two are in sliding connection. A punching laser head is embedded and installed inside the slider. The emitting end of the punching laser head faces vertically downward. An electric push rod is installed at the outer end of the installation box facing away. The telescopic end of the electric push rod extends into the inside of the installation box and is fixedly connected to the slider. A control console is installed on the front side of the lower end of the installation frame. The control console is internally provided with a control switch assembly.

[0009] The installation frame and the top plate jointly form the installation frame body of this device. The placement and positioning unit is used for the placement and fixation of the flange workpiece to be processed and centers it to ensure the accuracy of the subsequent hole-opening position; the installation sliding rods are used for the sliding installation of the sliders. The sliders are used for the installation of the punching laser heads and can drive the punching laser heads to move along the radius direction of the fitting cover plate under the push of the electric push rods to adjust the punching position; a set of hole-opening components are installed inside each installation box. The twelve installation boxes distributed in a circumferential array can provide three different hole-opening specifications: four holes, six holes, and twelve holes, which are suitable for the hole-opening processing of multiple models of flanges. The corresponding number of holes can be selected through the control console, and the control console controls the corresponding punching laser heads to work to achieve array hole-opening operations.

[0010] Furthermore, the array punching unit further includes a circular through hole, a receiver, and a distance sensor. A distance sensor is embedded and installed at one end of the slider away from the center position of the fitting cover plate close to it. A circular through hole is opened at one end of the installation box close to the distance sensor. The receiver is installed at the upper end of the fitting cover plate and close to the circular position. The receiver is a regular polygon structure and has twelve receiving surfaces on the outside. The distance sensor emits rays. When the receiver receives the rays, it obtains the displacement data of the punching laser head, and the position of the punching laser head participating in the hole-opening can be displayed on the display screen at the control console. The circular through hole can keep the light reception between the receiver and the distance sensor unobstructed.

[0011] Furthermore, the placement and positioning unit includes a protective bottom plate and a supporting bracket. A circular protective bottom plate is centrally installed on the upper side of the bottom of the mounting frame, and four supporting brackets are fixedly connected in a circumferential array around the protective bottom plate. The lower end of the supporting bracket is fixedly connected to the mounting frame, and a square limit block is fixedly connected to the outer side of the upper end of the supporting bracket. The protective bottom plate is used to block the laser instantaneously when the flange workpiece is laser-pierced, and the supporting bracket is used to lift the flange workpiece to an appropriate height to facilitate the hoisting rod to pass through the flange neck.

[0012] Furthermore, the placement and positioning unit further includes a first hydraulic cylinder, a hoisting rod, and a fitting cover plate. A first hydraulic cylinder is fixedly installed on the lower side of the top plate. The telescopic end of the first hydraulic cylinder faces downward and is fixedly connected to the hoisting rod. The hoisting rod vertically passes through the center of the fitting cover plate, and the two are fixedly connected. The first hydraulic cylinder drives the fitting cover plate to lift and lower through the hoisting rod, and controls the hoisting rod to insert into the neck of the flange workpiece.

[0013] Furthermore, the placement and positioning unit further includes a second hydraulic cylinder, a top block, and a displacement sensor. Four second hydraulic cylinders distributed in a circumferential array are embedded in a section of the hoisting rod located below the fitting cover plate. The telescopic ends of the second hydraulic cylinders extend horizontally outward, and a top block is fixedly connected to each telescopic end. The outer side of the top block is an arc structure, and a displacement sensor is embedded at the inner end of the top block facing inward. The second hydraulic cylinder pushes out the top blocks on the four sides, so that the top blocks are pressed against the inner wall of the flange neck, thereby achieving a fixing effect on the flange; and through the displacement sensor on the back of each top block, the moving distance of each top block can be obtained. By ensuring that the moving distances of the four top blocks are equal, it is further ensured that the hoisting rod is inserted at the exact center position of the flange workpiece, further ensuring the accuracy of the punching position.

[0014] Furthermore, the placement and positioning unit further includes a reference lamp. A reference lamp is embedded at the lower end of the hoisting rod, and the emitting end of the reference lamp faces vertically downward and is vertically corresponding to the center position of the protective bottom plate. By emitting light downward, the reference lamp can be used to preliminarily adjust the position of the flange workpiece when the flange workpiece is placed by observing the light circle projected through the flange neck.
