Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a rectangular tube cutting device for assembled buildings. Background Art

[0002] Prefabricated buildings are made by assembling and welding some prefabricated parts to form a sturdy building. The frame of the prefabricated building is welded with steel of various shapes and sizes, and the rectangular tubes are assembled and welded to obtain the desired prefabricated building frame.

[0003] The Chinese utility model patent with authorization announcement number CN220050226U is specifically "a rectangular tube cutting device for prefabricated buildings". The beneficial effects section of its specification records "a positioning structure is provided in the utility model, and the rectangular tube is supported by a first fixed block and a second fixed block, and the distance between the first fixed block and the second fixed block is adjusted according to the size of the rectangular tube to avoid the rectangular tube being too large to support the corner of the rectangular tube, so as to facilitate the cutting of rectangular tubes of various sizes in prefabricated buildings, and the inclined surfaces of the first fixed block and the second fixed block are used for positioning; a conveying structure is provided to move the rectangular tube when continuously cutting the rectangular tube, and the rectangular tube can be contacted with the side wall of the rectangular tube through a sliding column, so that the movement of the rectangular tube is more convenient, and the inclined surfaces of the first fixed block and the second fixed block are used to prevent the rectangular tube from detaching from the fixed block."

[0004] Although it is possible to cut rectangular tubes of different sizes by moving and adjusting the distance between the two fixed blocks, the adjustment speed is too slow. The number of rectangular tubes cut at the construction site is large, which reduces the overall construction progress. In addition, it is proposed to rotatably install a sliding column on the inclined surface of the fixed block in contact with the rectangular tube to facilitate the loading and unloading of the rectangular tube. However, due to the presence of the sliding column, the rectangular tube will not be firmly fixed when being cut, resulting in cutting errors. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a rectangular tube cutting device for assembled buildings, which can effectively solve the problems of low cutting efficiency and large cutting error in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a rectangular tube cutting device for assembled buildings, comprising a machine base and a cutting assembly installed on the top of the machine base, two supporting assemblies each comprising a mounting frame symmetrically distributed about the cutting assembly and fixedly installed on the top of the machine base, a supporting belt being connected between two opposite inner side walls of the mounting frame, a lifting assembly comprising a fixing seat respectively lifting and slidingly installed on the side away from the two mounting frames, a rotating roller being rotatably installed between the two opposite inner side walls of the fixing seat, and also comprising an extrusion seat which is synchronously lifted and lifted with the fixing seat and is located on the opposite side of the two mounting frames.

[0008] Furthermore, a bottom plate is fixedly installed between two opposite inner side walls of the machine base, and four square through holes distributed in a rectangular array and two circular through holes symmetrically distributed about the cutting assembly are opened through the top and bottom of the machine base.

[0009] Furthermore, the cutting assembly includes two frames fixedly mounted on the top of the machine base, and a first lifting cylinder is fixedly mounted on the top of the frames.

[0010] Furthermore, the output end of the first lifting cylinder extends through and under the frame and is installed with a driving motor, and the output end of the driving motor is installed with a cutting blade.

[0011] Furthermore, the lifting assembly also includes a second lifting cylinder fixedly installed at the bottom center of the bottom plate, and the output end of the second lifting cylinder extends through the top of the bottom plate and installs the lifting plate.

[0012] Furthermore, two lifting rods are vertically fixedly installed on the top of the lifting plate, which slide through the corresponding circular through holes and are installed on the bottom of the corresponding fixed seats. Extrusion seats are fixedly installed on both sides of the lifting plate, which slide through the corresponding square through holes.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. First, install two support belts for supporting the rectangular tube on the top of the machine base. Since the support belts can be bent and deformed, they have good wrapping properties for rectangular tubes of different specifications. Then, an extrusion seat that can lift and extrude the rectangular tube is set above the machine base. Through the extrusion of the extrusion seat and the support of the support belt, rectangular tubes of different specifications can be quickly limited and fixed, reducing cutting errors while improving cutting efficiency.

[0015] 2. In order to facilitate the feeding and unloading of rectangular tubes, rotating rollers that rise and fall synchronously with the extrusion seat are installed on the side away from the two support belts. Through the rolling of the rotating rollers, the rectangular tubes can be quickly fed in and out without affecting the cutting of the rectangular tubes, which is easy to use.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example 1

[0025] Reference Figure 1-4, which is the first embodiment of the utility model, discloses a rectangular tube cutting device for assembled buildings, including a machine base 1, and a cutting component 2 installed on the top of the machine base 1, two supporting components each include a mounting frame 11 symmetrically distributed about the cutting component 2 and fixedly installed on the top of the machine base 1, and a supporting belt 12 is connected between the two opposite inner side walls of the mounting frame 11. The material of the supporting belt 12 is not unique, and it can be a metal belt, a rubber belt, etc., and its purpose is to provide wrapping support for rectangular tubes of different specifications. The lifting component 3 includes a fixed seat 34 that is respectively lifted and slidably installed on the side away from the two mounting frames 11, and a rotating roller 35 is rotatably installed between the two opposite inner side walls of the fixed seat 34. The rotation of the rotating roller 35 can facilitate the feeding and discharging of the rectangular tube. It also includes an extrusion seat 36 that is synchronously lifted and lowered with the fixed seat 34 and is located on the opposite side of the two mounting frames 11. After the extrusion seat 36 is lowered, it squeezes and resists the rectangular tube, and cooperates with the supporting belt 12 to quickly limit and fix rectangular tubes of different specifications.

[0026] Example 2

[0027] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a bottom plate 13 is fixedly installed between two opposite inner side walls of the base 1, and four square through holes 14 distributed in a rectangular array and two circular through holes 15 symmetrically distributed about the cutting assembly 2 are opened at the top and bottom of the base 1. The cutting assembly 2 includes two frames 21 fixedly installed on the top of the base 1, and a first lifting cylinder 22 is fixedly installed on the top of the frame 21. The output end of the first lifting cylinder 22 extends through the frame 21 and is installed with a driving motor 23. The output end of the driving motor 23 is installed with a cutting blade 24. The cutting blade 24 is provided in the attached manual. Figure 3 It can be known that the cutting blade 24 is detachably mounted on the output end of the driving motor 23, and the lifting assembly 3 also includes a second lifting cylinder 31 fixedly mounted at the bottom center of the bottom plate 13. The output end of the second lifting cylinder 31 extends through and extends to the top of the bottom plate 13 and is installed with a lifting plate 32. The lifting plate 32 will not contact and wear with the machine base 1 during the lifting process. Two lifting rods 33 are vertically fixedly installed on the top of the lifting plate 32, which slide through the corresponding circular through holes 15 and are installed at the bottom of the corresponding fixed seat 34. The outer diameter of the lifting rod 33 is consistent with the inner diameter of the circular through hole 15, ensuring that the lifting rod 33 is stably and reliably lifted. Extrusion seats 36 that slide through the corresponding square through holes 14 are fixedly mounted on both sides of the lifting plate 32. The single-sided cross-sectional specifications of the extrusion seat 36 are adapted to the square through holes 14, ensuring that the lifting rod 33 is stably and reliably lifted.

[0028] The remaining structures are the same as those of Example 1.

[0029] First, a cutting line is drawn on the rectangular tube to be cut, and the rectangular tube is placed on two rotating rollers 35. By using the rotating rollers 35, the position of the rectangular tube is adjusted under the premise of reducing wear, so that the cutting line on the rectangular tube is opposite to the cutting blade 24.

[0030] Secondly, the second lifting cylinder 31 is started to drive the lifting plate 32, the lifting rod 33, the fixing seat 34, the rotating roller 35 and the extrusion seat 36 to descend synchronously. As the height of the rotating roller 35 is lowered, the rectangular tube placed on the rotating roller 35 will also be lowered synchronously until it contacts the support belt 12 and stops descending. After the extrusion seat 36 continues to descend, it will press against the top of the rectangular tube and cooperate with the support limit of the support belt 12 to achieve the limit fixation of the rectangular tube. At this time, the rotating roller 35 is lowered too low and no longer contacts the rectangular tube.

[0031] Finally, the drive motor 23 is started to drive the cutting blade 24, and the first lifting cylinder 22 is started synchronously to drive the drive motor 23 and the cutting blade 24 to descend synchronously to cut the fixed rectangular tube. After cutting, the first lifting cylinder 22 is started to drive the cutting blade 24 to rise, and the second lifting cylinder 31 is started to drive the lifting plate 32, the lifting rod 33, the fixed seat 34, the rotating roller 35 and the extrusion seat 36 to rise synchronously. At this time, the extrusion seat 36 no longer squeezes and contacts the rectangular tube, and the rising rotating roller 35 begins to contact the bottom of the rectangular tube and drives the rectangular tube to rise. At this time, the rectangular tube is no longer in contact with the support belt 12. The rotating roller 35 can easily rotate, so that the cut rectangular tube can be easily taken out.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. 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 replace some of the technical features therein by equivalents. 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 embodiments of the present invention.
