Description

Technical Field

[0001] The invention relates to the technical field of angle steel cutting devices, and in particular to an angle steel cutting device. Background Art

[0002] The angle cutting process in the production and processing of angle steel for transmission line tower components usually involves manually transferring the angle steel workpiece to the cutting station for angle cutting after the hole making process is completed.

[0003] The existing angle steel cutting method has the following shortcomings:

[0004] 1) In a separate angle cutting machine, the operator marks the angle according to the drawing, then manually moves the angle steel and rotates the angle cutting die to cut the angle steel. This method relies heavily on manual labor, resulting in unstable processing accuracy, low production efficiency, and high labor intensity for operators. At the same time, the transfer of workpieces between different workstations (such as hoisting) not only increases working time, but also takes up a lot of production space.

[0005] 2) Automatic angle steel chamfering machine processing: This method is used to transfer the fixed-length angle steel after hole making to the automatic angle steel chamfering machine for further chamfering. Although the degree of automation has improved, it still does not solve the problem of workpieces needing to be transferred between different equipment. This also leads to the fragmentation of production processes, site occupation and dependence on professional operators. Summary of the Invention

The mounting plate 9 is fixedly connected to the first guide plate 801 or the second guide plate 802, the rotating shaft 10 is fixedly connected to the mounting plate 9, and the roller 11 is coaxially connected to the rotating shaft 10. The axes of the rotating shafts 10 of the two groups of rolling assemblies are respectively parallel to the A surface 28 and the B surface 29 of the angle steel to be cut. By setting two groups of rolling assemblies, the feeding and discharging of the angle steel to be cut can be facilitated.

[0063] More specifically, the first corner cutting assembly 13 and the second corner cutting assembly 14 have the same structure. The first corner cutting assembly 13 is used as an example for description. Figures 8-10 As shown, the first cutting angle assembly 13 is composed of a tool holder 1301, an upper tool seat 1302, a lower tool seat 1303, an upper cutter 1304 and a lower cutter 1305.

The through hole 1306 matches the shape of the upper cutter 1304 and can be used for the upper cutter 1304 to pass through. A material trough 1308 is also provided at the lower part of the knife holder 1301. The material trough 1308 is as shown in FIG. Figure 10 As shown, it is located directly below the through hole 1306 and the two are connected. The two ends of the material trough 1308 pass through the lower part of the tool holder 1301, and the lower end surface is an inclined surface with a high middle and low sides. When the upper cutter 1304 cuts the angle steel, the waste can enter the material trough 1308 through the through hole 1306 and be discharged to the outside of the tool holder 1301.

[0071] The second cutting unit III Figure 1 and Figure 7 As shown, the second slide 17, the third corner cutting assembly 18, the fourth corner cutting assembly 19, the second sliding drive assembly 20 and the second longitudinal drive assembly 21, the third corner cutting assembly 18 and the fourth corner cutting assembly 19 are arranged in a Figure 7 The third and fourth cutting components 18 and 19 are respectively located on the right and left sides of the second workbench 5 in the viewing direction, and the third cutting component 18 and the fourth cutting component 19 are respectively connected to the second slide 17 through a set of rotary drive components 22. The rotation axis is distributed along the B surface 29 perpendicular to the angle steel to be cut. The first cutting unit II is rotated 180° clockwise along the center line of the center of the feeding hole 6 of the middle side plate 2 in the vertical direction to obtain the second cutting unit III. Therefore, the overall structure of the second cutting unit III is the same as that of the first cutting unit II, with the following differences:

[0072] The second slide 17 slides above the second workbench 5 in a width direction parallel to the B surface 29 of the angle steel;

[0073] The second sliding drive assembly 20 is connected between the second slide 17 and the second side plate 3;

[0074] The piston rod axis in the second longitudinal drive assembly 21 is distributed along a plane perpendicular to the B surface 29 of the angle steel;

[0075] The third chamfering assembly 18 and the fourth chamfering assembly 19 are connected to the upper part of the second slide 17 in a direction perpendicular to the plane of the B surface 29;

[0076] Therefore, in this embodiment, the specific structure of the second cutting unit III will not be described in detail.

[0077] by Figure 14 Taking the angle steel to be cut as an example, the working principle of the solution of the present invention is described in detail:

[0078] In this embodiment, the A surface 28 of the angle steel to be cut includes a portion 1 to be cut 2801 and a portion 2 to be cut 2802, and the B surface 29 includes a portion 3 to be cut 2901 and a portion 4 to be cut 2902, wherein the portion 4 to be cut 2902 is located on the inner side of the B surface 29 and is connected to the A surface 28; the angle steel slides into the first angle cutting assembly 13 and the second angle cutting assembly 14 through the roller 11 in the rolling assembly, and the feeding direction is from Figure 14 Starting from the left end, at this time, the A surface 28 is parallel to the first workbench plate 4, and the B surface 29 is perpendicular to the first workbench plate 4; the first cutting component 13 is used to cut the second part 2802 to be cut, and the angle steel moves backward as a whole, and continues to cut the first part 2801 to be cut by the first cutting component 13; then the angle steel continues to move backward to the second cutting unit III, and the third cutting component 18 cuts the third part 2901 to be cut. After the fourth cutting component 19 passes through the first part 2801 to be cut and the second part 2802 to be cut, it cuts the fourth part 2902 to be cut on the inner side of the B surface 29. After the angle steel is cut, it can be cut at the appropriate position of the angle steel by the subsequent cutting device.

[0079] It should be noted that if Figure 14 After the angle steel to be cut is rotated 180°, the processing process is as follows:

[0080] Feed direction Figure 14 Feeding starts from the right end as shown. At this time, the A surface 28 is perpendicular to the first workbench 4 and the B surface 29 is distributed parallel to the first workbench 4. First, the third part to be cut 2901 is cut by the first cutting component 13; then, the angle steel is moved as a whole to the second cutting unit III, and the third cutting component 18 is used to cut the first part to be cut 2801 and the second part to be cut 2802 in turn; then, the angle steel returns to the first cutting unit II, and the second cutting component 14 passes through the first part to be cut 2801 and the second part to be cut 2802 and then cuts the fourth part to be cut 2902.

[0081] That is, when it is necessary to cut the inner side of the A side 28 or the B side 29 of the angle steel, this device must first cut the outer side of the B side 29 or the A side 28 through a certain group of cutting units, and then use another group of cutting units to cut through the B side 29 or the A side 28 and then cut the inner side of the A side 28 or the B side 29 to solve the problem of difficult cutting operation on the inner side of the angle steel.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
