Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a cutting device used for metal door and window engineering. Background Art

[0002] During the processing of metal doors and windows, some pipes need to be cut and processed on site. The general cutting process is often to cut a piece of raw steel pipe in a quantitative manner. The more common cutting method is for workers to cut the steel pipe with a handheld cutting machine. In this cutting method, the cutting stability and cutting angle depend on the experience of the workers, so the cutting accuracy is often not high. When the demand for a single size of accessories at the construction site is large, the efficiency of manual pipe cutting cannot match the efficiency of door and window assembly, which leads to low assembly efficiency of metal doors and windows. Therefore, a cutting device for metal door and window engineering is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In this embodiment, refer to Figure 1-3 , a cutting device for metal door and window engineering, including a cutting table 1, a guide slide 5 is provided on the table surface of the cutting table 1, and a plurality of groups of guide rollers 6 arranged in sequence are arranged on the guide slide 5. A conveying disc 4 is provided in the middle of the guide slide 5, and an annular groove 18 is provided along the circumferential surface of the conveying disc 4. The steel pipe workpiece 16 is slid into the guide slide 5. It should be particularly noted that the groove spacing of the annular groove 18 is consistent with the width of the guide slide 5. The steel pipe workpiece 16 slides into the annular groove 18 of the conveying disc 4 and slides forward due to the rotation of the conveying disc 4. Since the annular groove 18 is curved, no matter how much the conveying disc 4 rotates, the top of the inner annular groove 18 is convex compared to the guide slide 5. As the conveying disc 4 rotates, it can naturally drive the steel pipe workpiece 16 to slide forward.

[0022] As attached Figure 2 And attached Figure 3 As shown, installation cavities 8 are respectively opened at corresponding positions of the front and rear disk surfaces of the conveying disk 4, and at least two groups of parallel swing arms 10 are rotatably connected in the installation cavities 8. The fixed ends of the swing arms 10 are rotatably connected in the installation cavities 8 through their own fixed shafts 9.

[0023] The movable ends of the multiple swing arms 10 on the same side are all rotatably connected to the same mounting block 11. The mounting blocks 11 on both sides are symmetrically located. The inner surfaces of the two mounting blocks 11 facing each other are provided with cutting wheels 12. Each mounting block 11 is provided with a power motor for controlling the rotation of the respective cutting wheels 12. The outer surfaces of the two mounting blocks 11 facing away from each other are provided with cone blocks 13, and the cone blocks 13 are provided with inclined surfaces. It should also be noted that, as shown in the attached figure, Figure 3 As shown, the installation cavities 8 on both sides of the conveying disc 4 are respectively provided with avoidance openings 17 on the cavity walls thereof which are in communication with the annular groove 18 , and the cutting wheels 12 on both sides extend into the annular groove 18 from the avoidance openings 17 on their respective sides.

[0024] A translation block 14 that can be telescoped forward and backward is installed above the cutting table 1 through a hydraulic rod. The translation block 14 is suspended above the cutting table 1. Push columns 15 are respectively arranged on both sides of the bottom surface of the translation block 14. The push columns 15 on both sides extend downward respectively and their columns push against the cone blocks 13 on each side during the forward and backward translation process.

[0025] When the translation block 14 moves forward, the push columns 15 on both sides will push their respective cone blocks 13, and make the multiple sets of parallel swing arms 10 rotate synchronously, so that the cutting wheels 12 on both sides can just cut into the annular groove 18 along the longitudinal direction, and perform linear cutting on the steel pipe workpiece 16 in the annular groove 18. It is particularly noted that the cuts of the two cutting wheels 12 are relatively staggered. Since the cutting of the cutting wheel 12 is generally a straight line, the two cutting wheels 12 only need to be slightly staggered to ensure that the blades do not touch each other during cutting.

[0026] Since the cutting wheels 12 are arranged on both sides, a single cutting wheel 12 only needs to move forward half the width of the steel pipe workpiece 16. The cutting wheels 12 on both sides can cut synchronously to achieve the purpose of completely cutting off the steel pipe.

[0027] A control box 2 is arranged at the front side of the cutting table 1, and a grooved wheel mechanism 3 is arranged in the control box 2. The grooved wheel mechanism 3 rotates coaxially with the conveying disc 4 through a rotating shaft 7 arranged at its output end. Figure 1 It can be seen that the grooved wheel mechanism 3 includes an active dial and a passive grooved disc. The passive grooved disc is connected to the transmission disc 4 via a rotating shaft 7. A transmission motor 19 for driving the active dial to rotate is arranged outside the control box 2.

[0028] The grooved wheel mechanism 3 is used to accurately control the length of the steel pipe workpiece 16 cut each time. In this embodiment, the passive grooved disc of the grooved wheel mechanism 3 is designed with four notches. Therefore, every time the passive grooved disc rotates 360°, the corresponding conveying disc 4 just rotates one circle and conveys the steel pipe workpiece 16 forward a fixed distance. Here, the passive grooved disc of the grooved wheel mechanism 3 can also be designed with other numbers of notches.

[0029] Since the grooved wheel mechanism 3 has the characteristic of intermittent rotation, when the conveying disc 4 rotates one circle and is in a stopped state, the translation block 14 can be controlled to move forward, and the two cutting wheels 12 can be controlled to move synchronously toward the middle through the push column 15 to achieve cutting. After the cutting is completed, the conveying disc 4 continues to rotate, and can continuously cut out steel parts with precise dimensions in the subsequent working process.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
