Description

Technical Field

[0001] The present application relates to the technical field of steel pipe processing equipment, and in particular to a football goal steel pipe chamfering device and a production process. Background Art

[0002] Football goal steel pipes usually refer to the steel pipe materials used to make football goal frames. Football goal steel pipes are usually made of galvanized steel pipes, and the surface is electrostatically sprayed to enhance wear resistance and rust resistance. The selection of steel pipes must consider strength, weather resistance and safety to ensure that the football goal can be used stably in all weather conditions without causing harm to the players.

[0003] Specifically, the goal posts and crossbars can be made of φ89×3 high-quality steel pipes, the two side braces are made of φ32×2.5 steel pipes, and the two side crossbars and the rear crossbar are made of 70×50×3 and 50×50×3 square pipes respectively. After the primary treatments such as pickling and phosphating, these steel pipes are surface treated on an automatic spraying line to improve their durability and appearance quality. In addition, there are also painted football goals on the market, which are made of stainless steel, can be disassembled and assembled, have good stability, and are suitable for field use.

[0004] In the production process of football goal steel tubes, an elliptical notch is usually cut in the middle of the round tube, and then the round tube is bent from both ends to the middle to form a chamfer of the cut workpiece.

[0005] In the related art, a laser cutting machine is usually used to cut a round tube. Specifically, the steel tube is fixed under the cutting tool, and then the laser tool is controlled to cut according to a certain contour. However, in the above process, it is necessary to complete the cutting of an elliptical pattern on the round tube, and then the cut waste is peeled off from the notch.

[0008] By adopting the above scheme, the round tube can be placed in the limiting groove, and the position of the round tube in the limiting groove can be limited by the fixing component. Then, the first hydraulic cylinder can be controlled to drive the slide plate to descend, so that the cutting head can be inserted into the round tube.

[0015] Optionally, the cutting head includes a main cutting knife and two pairs of sub-cutting knives, the main cutting knife is located between the two pairs of sub-cutting knives, and a connecting component for connecting the main cutting knife and the sub-cutting knives is provided between the two.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0028] First aspect Example 1

[0029] A soccer goal steel pipe chamfering production device, referring to Figure 1 and Figure 2 , including a processing table 1 erected on the ground, the processing table 1 is arranged in a rectangular parallelepiped shape. A bottom plate 2 is fixedly connected to the processing table 1, and the bottom plate 2 is arranged in a rectangular parallelepiped shape. A lower template 3 is fixedly connected to the bottom plate 2, and the lower template 3 is arranged along the length direction of the bottom plate 2. A limiting groove 31 for limiting the round tube is opened on the upper end surface of the lower template 3, and the limiting groove 31 is arranged along the length direction of the lower template 3. A cutting groove 32 is opened in the middle section of the length direction of the lower template 3, and the cutting groove 32 is arranged in a V shape and is connected to the limiting groove 31.

[0030] The bottom plate 2 is fixedly connected to a support frame 4, and a slide plate 5 is slidably connected to the support frame 4. The sliding direction of the slide plate 5 on the support frame 4 is perpendicular to the upper end surface of the processing table 1. A cutting head 6 for cutting the round tube is installed on the slide plate 5. The cutting head 6 is set in a triangular shape and matches the contour of the cutting groove 32. A first hydraulic cylinder 7 is fixedly connected to the upper end of the support frame 4. The piston rod of the first hydraulic cylinder 7 is fixedly connected to the slide plate 5. The extension direction of the first hydraulic cylinder 7 is parallel to the sliding direction of the slide plate 5 on the support frame 4.

[0031] Thus, the round tube can be placed in the limiting groove 31, and then the first hydraulic cylinder 7 is controlled to drive the slide plate 5 to descend, so that the cutting head 6 is inserted into the round tube.

[0032] The slide plate 5 is provided with a moving assembly 9 for driving the cutting head 6 to reciprocate, and the moving assembly 9 includes a moving plate 91, and the moving plate 91 is parallel to the upper end surface of the bottom plate 2. The moving plate 91 is slidably connected to the support frame 4, and the sliding direction of the moving plate 91 on the support frame 4 is perpendicular to the opening direction of the limit groove 31. The slide plate 5 is fixedly connected with a moving cylinder 92, and the piston rod of the moving cylinder 92 passes through the slide plate 5 and is fixedly connected to the moving plate 91.

[0033] Therefore, when the cutting blade 6 is inserted into the round tube, it can be extended and contracted by controlling the moving cylinder 92, so that the cutting blade 6 can move the two sides of the cutting position of the round tube, so that the waste material at the notch of the steel tube is peeled off. At the same time, in order to improve the connection effect between the moving plate 91 and the slide plate 5, the upper end of the moving plate 91 is fixedly connected to the limit block 10, and the slide plate 5 facing the limit block 10 is provided with a guide groove 51, and the limit block 10 is slidably connected in the guide groove 51.

[0034] The processing table 1 is provided with a fixing assembly 8 for fixing the steel pipe in the limiting groove 31. The fixing assembly 8 includes a limiting plate 81, an abutting plate 82 and an adjusting cylinder 83, and the telescopic direction of the adjusting cylinder 83 is parallel to the upper end surface of the processing table 1. The adjusting cylinder 83 and the limiting plate 81 are both fixedly connected to the processing table 1, and the limiting plate 81 is used to preliminarily limit the position of the round pipe. The abutting plate 82 is fixedly connected to the end of the piston rod of the adjusting cylinder 83, and the bottom plate 2 is placed between the limiting plate 81 and the abutting plate 82.

[0035] Therefore, the telescopic length of the adjusting cylinder 83 can be changed according to the length and processing position of the round tube, thereby changing the position of the abutment plate 82, thereby calibrating the cutting position of the round tube.

[0036] Therefore, the round tube can be placed in the limiting groove 31, and the position of the round tube in the limiting groove 31 can be limited by the fixing component 8, and then the first hydraulic cylinder 7 can be controlled to drive the slide plate 5 to descend, so that the cutting head 6 can be inserted into the round tube, and then the cutting head 6 can be moved, and the moving position of the cutting head 6 can be limited by the cutting groove 32, so that the steel tube can be quickly cut. Example 2

[0037] The difference from Example 1 is: Figure 3 , Figure 4 and Figure 5 The cutting head 6 includes a main cutting knife 61 and two pairs of sub-cutting knives 62. The same pair of sub-cutting knives 62 are arranged opposite to each other, and the sub-cutting knives 62 are arranged in a V shape. The main cutting knife 61 is located between the two pairs of sub-cutting knives 62, and a connecting component 11 for connecting the main cutting knife 61 and the sub-cutting knives 62 is provided between the main cutting knife 61 and the sub-cutting knives 62.

[0038] The connecting assembly 11 includes a guide housing 111, which is set in a triangular shape. The guide housing 111 is fixedly connected to the lower end of the slide plate 5. A sliding hole 1111 for sliding the sub-cutting knife 62 is provided on the guide housing 111, and the sliding hole 1111 is set along the hypotenuse of the guide housing 111, and the lower parts of the two slide grooves on the same surface are extended and connected to each other. The sub-cutting knife 62 is penetrated and slidably connected in the sliding hole 1111. The tip of the main cutting knife 61 is set in a triangular shape, and the tip of the sub-cutting knife 62 is set in a bevel shape. When the main cutting knife 61 reaches the maximum downward displacement, the tips of the sub-cutting knife 62 heads 6 on both sides of the main cutting knife 61 abut against each other. An abutting rod 112 is provided in the guide housing 111, and the abutting rod 112 is fixedly connected to the main cutting knife 61, and the abutting rod 112 abuts against the sub-cutting knife 62 and drives the sub-cutting knife 62 to slide in the sliding hole 1111.

[0039] The upper end of the slide plate 5 is fixedly connected to a second hydraulic cylinder 12, and the extension direction of the second hydraulic cylinder 12 is perpendicular to the upper end surface of the processing table 1. The piston rod of the second hydraulic cylinder 12 passes through the slide plate 5 and is fixedly connected to the main cutting knife 61.

[0040] Therefore, when the second hydraulic cylinder 12 drives the main cutting knife 61 to descend, the abutment rod 112 can descend together with the main cutting knife 61, and then the abutment rod 112 will move the sub-cutting knife 62, so that the sub-cutting knife 62 slides in the sliding hole 1111, and then the sub-cutting knife 62 cuts the steel pipe under the restriction of the sliding hole 1111.

[0041] In order to improve the cutting efficiency of the second cutting knife, a connecting rod 13 is fixedly connected between two adjacent sub-cutting knives 62. The connecting rod 13 is set as a telescopic rod with a variable length in the prior art, and the end of the abutting rod 112 abuts against the connecting rod 13. An arc-shaped guide platform 14 is fixedly connected to the outer wall of the guide housing 111. When the sub-cutting knife 62 slides on the sliding hole 1111, the arc-shaped guide platform 14 abuts against the end of the sub-cutting knife 62.

[0042] The connecting rod 13 is configured as a telescopic rod, so that when the cutting knife 62 slides on the sliding hole 1111, and when the cutting knife 62 passes through the arc guide platform 14, the cutting knife 62 will move to the side away from the arc guide platform 14 under the abutment of the guide platform, thereby causing the cutting knife 62 to produce a certain position movement during cutting.

[0043] Therefore, the main cutting knife 61 can be driven down by the second hydraulic cylinder 12, so that the main cutting knife 61 first performs a preliminary cut on the cutting part of the steel pipe. At the same time, the main cutting knife 61 will drive the abutment rod 112 to descend, and then the abutment rod 112 drives the sub-cutting knife 62 to cut the round pipe, cutting both sides of the main cutting knife 61, so that a notch is quickly produced.

[0044] Second aspect The present application also discloses a soccer goal steel pipe chamfering production process, using the soccer goal steel pipe chamfering device described above, comprising the following steps: S1: placing the round tube in the limiting groove 31 and limiting the position of the round tube in the limiting groove 31 by the fixing assembly 8. S2: Then, the first hydraulic cylinder 7 is controlled to drive the slide plate 5 downward, so that the cutting head 6 is inserted into the round tube; S3: Then, the cutting head 6 is moved, and the moving position of the cutting head 6 is limited by the cutting groove 32, so that the steel pipe is quickly cut.
