Description

Technical Field

[0001] The utility model relates to the field of H-shaped steel processing, in particular to a bevel cutting machine for H-shaped steel. Background Art

[0002] After searching the patent document with the announcement number CN217701875U, the first laser cutting head and the second laser cutting head are respectively moved on the steel surface for cutting by moving the first screw slide and the second screw slide moving end. The angle between the laser cutting head and the steel surface can be adjusted by driving the first motor output end and the second motor output end, so as to process grooves of different inclinations on the steel. The third laser cutting head can perform groove cutting on the steel web through the coordinated movement of the telescopic end of the electric hydraulic rod, the output end of the third motor and the moving end of the third screw slide.

[0003] This patent uses three laser cutting heads to cut the grooves of H-shaped steel, and the laser cutting head located on the lower side is easily blocked by the melted cutting slag. At the same time, using multiple laser cutting heads to control the postures of the three laser cutting heads separately will obviously increase the cost of the entire cutting machine, and the control of the three cutting heads is relatively cumbersome and inconvenient to operate.

A notch for facilitating the sliding of the clamping frame 45 is opened at the lower end of the adjustment frame 43, and a guide strip matching the notch of the adjustment frame 43 is fixed on the outer side of the clamping frame 45. The adjustment component 44 includes a fixing on the adjustment frame 4 3, a bevel gear ring 441 is meshed with a bevel gear 442 on one side of the bevel gear ring 441, and the bevel gear 442 is fixed to the rotating part of the adjusting motor 443, and the adjusting motor 443 is fixed to the top of the lifting frame 42. The lifting frame 42 is pushed by the telescopic part of the hydraulic rod 41 to drive the adjusting frame 43 to move downward, and then the distance between the laser cutting head 5 and the H-shaped steel is adjusted. At the same time, the rotating part of the adjusting motor 443 is used to drive the bevel gear 442 to rotate, and the laser cutting head 5 at the lower end of the adjusting frame 43 is turned forward and backward with the lower end of the lifting frame 42 as the center through the bevel gear 442 and the bevel gear ring 441, and then adjusted according to the contour of the H-shaped steel.

[0032] In this embodiment: the support mechanism 1 includes a base 11, two symmetrical brackets 12 are fixed in the middle position of the base 11, and a T-shaped track is opened on the upper side of the bracket 12. The base 11 is used to support the conveying mechanism 2, and the bracket 12 is used to support the moving mechanism 3.

[0033] In this embodiment: the moving mechanism 3 includes a moving motor 31 fixed to the front side of the bracket 12, a moving screw 32 is rotatably connected to the inner side of the bracket 12, a moving frame 33 is slidably connected to the T-track of the bracket 12, the rear ends of the two moving screws 32 are connected by a synchronous belt drive, the fixed part of the hydraulic rod 41 is installed on the moving frame 33, and the ends of the two clamping frames 45 that are away from each other are fixed with a tensioning spring for pushing the two clamping seats 46 closer together, the moving screw 32 is driven to rotate by the rotating part of the moving motor 31, and the two moving screws 32 are driven to rotate synchronously by the synchronous belt drive at the rear end of the moving screw 32, and then the moving frame 33 is driven to move back and forth along the T-track of the bracket 12 through the synchronous rotation of the two moving screws 32, and then the H-shaped steel is cut.

[0034] In this embodiment: the conveying mechanism 2 includes a conveying motor 21, which is fixed on the front side of the base 11. Three conveying rollers 22 arranged in a linear array are rotatably connected to the inner side of the base 11. The three conveying rollers 22 are covered with a conveyor belt 23 on the outer side. The conveying motor 21 is used to drive the conveying rollers 22 at the rear end to rotate, and the conveying belt 23 and the H-shaped steel placed thereon are driven to move by the rotation of the conveying rollers 22.

[0035] Working principle: When in use, first place the H-shaped steel on the conveyor belt 23 of the three sets of conveyor rollers 22 in an H-shaped state, and then the web of the entire H-shaped steel is in a horizontal state. At this time, the rotating part of the conveying motor 21 drives the conveyor roller 22 at its rear end to rotate, and the conveyor belt 23 and the H-shaped steel placed thereon are driven to move through the rotation of the conveyor roller 22;

[0036] When the H-shaped steel moves to the position where the groove needs to be cut, the conveying motor 21 stops rotating, and the moving motor 31 starts and drives the moving screw 32 to rotate. The two moving screws 32 are rotated synchronously to drive the moving frame 33 to move to the front position of the H-shaped steel. Then, the telescopic parts of the two hydraulic rods 41 simultaneously push the lifting frame 42 to move downward. At this time, the rotating part of the adjusting motor 443 drives the bevel gear 442 to rotate. Through the meshing of the bevel gear 442 and the bevel gear ring 441, the adjusting frame 43 can be flipped backward with the lower end of the lifting frame 42 as the center, and then the laser cutting head 5 clamped by the clamping frame 45 and the clamping seat 46 is flipped backward. When the laser cutting head 5 is perpendicular to the front side of the H-shaped steel and is located at its lower edge, the extension of the telescopic part of the hydraulic rod 41 and the rotation of the adjusting motor 443 are stopped; at this time, the distance from the laser cutting head 5 to the H-shaped steel is adjusted by the backward movement of the moving frame 33;

[0037] When the laser cutting head 5 is started to cut the H-shaped steel, the lifting frame 42 and the adjusting frame 43 are first driven upward by the telescopic part of the hydraulic rod 41, so that the front side of the H-shaped steel is cut by the laser cutting head 5;

[0038] Then, when cutting the web of the H-shaped steel, the adjusting frame 43 is flipped by the adjusting assembly 44 so that the laser cutting head 5 at the lower end thereof is vertically facing downward, and at the same time, the height of the laser cutting head 5 is adjusted by the hydraulic rod 41, and then the web of the H-shaped steel is longitudinally cut under the drive of the moving mechanism 3;

[0039] In addition, the cutting action on the front side of the H-beam is repeated in reverse, so as to cut the back side of the H-beam, and then the entire cutting action is completed. When the laser cutting head 5 needs to swing on both sides, the two hydraulic rods 41 are extended to different lengths, so that the lifting frame 42 can drive the adjustment frame 43 and the laser cutting head 5 to swing and adjust on both sides.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
