Description

Technical Field

[0001] The utility model belongs to the technical field of circular saw machines, and in particular relates to a metal circular saw machine for cutting pipe sections. Background Art

[0002] Circular saw machines can be divided into metal circular saw machines and woodworking circular saw machines according to the processed products. According to the feeding method, they can be divided into vertical, horizontal and scissor-type. According to the control method, they can be divided into manual, semi-automatic and fully automatic. And they can be equipped with special material racks according to the needs.

[0003] In the Chinese patent with publication number CN 216882029 U, the metal circular saw machine for pipe segment cutting is mentioned. The straight pipe is placed on a V-shaped support frame and a V-shaped rotating frame, and the driving motor and the metal circular saw body are started. After being transmitted by the transmission belt, the transmission screw rotates, and the metal circular saw body moves forward after being driven by the transmission screw. The metal circular saw body cuts the straight pipe into pipe segments. At this time, the moving frame continues to move forward, and the bottom of the front end of the metal circular saw body contacts the L-shaped part. At this time, the V-shaped rotating frame loses balance and rotates, and the front side wall of the V-shaped rotating frame tilts downward. Under gravity operation, the cut pipe segment automatically rolls off the V-shaped rotating frame, and the driving motor reverses, and the moving frame drives the metal circular saw body to reset. Under the action of the elastic reset component, the V-shaped rotating frame resets, and the straight pipe is cut by machinery instead of manual labor, thereby reducing the amount of manual operation and improving the straight pipe cutting efficiency.

[0004] However, the above device has the following problems when used:

[0005] After cutting the straight pipe, the V-shaped rotating frame is driven to rotate through the cooperation of its internal parts to discharge the cut pipe. However, the V-shaped rotating frame does not rotate around the center of the pipe during rotation. The frame body of the V-shaped rotating frame will hinder the advancement of the straight pipe. Therefore, the straight pipe feeding operation can only be carried out after the V-shaped rotating frame returns to its original state, which prolongs the straight pipe feeding time.

Based on the embodiments in 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.

[0028] Reference Figure 1-Figure 7 A metal circular saw machine for pipe section cutting comprises a cutting base plate 1 and a circular saw machine body 2. The circular saw machine body 2 is used to cut a pipe body located on a fixed arc frame 3. A fixed arc frame 3 for storing the pipe body is installed on the cutting base plate 1. A flip arc frame 4 is arranged on the side of the circular saw machine body 2 away from the fixed arc frame 3. Both the fixed arc frame 3 and the flip arc frame 4 are arranged in a V shape. The circular saw machine body 2 is installed on a cutting bracket. A rotating shaft is inserted at the bottom of the cutting bracket. The rotating shaft is rotatably installed on a base 5. The base 5 is fixedly installed on the cutting base plate 1. The rotating shaft is connected to an angle adjustment motor for driving the rotation thereof. The angle adjustment motor drives the cutting bracket and the circular saw machine body 2 thereon to rotate through the rotating shaft. The circular saw machine body 2 is located on the upper side of the pipe body. It rotates from top to bottom to cut the pipe body on the lower side and cut the pipe body into a suitable length.

[0029] In a further embodiment, after the circular saw machine body 2 cuts the pipe body, it is lifted up and returns to the starting position. In order to unload the cut pipe body, it is necessary to rotate the flip arc frame 4, and the pipe body can fall from the flip arc frame 4 under the action of its own gravity. During the rotation of the flip arc frame 4, if the center of the pipe body is not taken as the center of the circle, the pipe body on the fixed arc frame 3 will be hindered by the rotating flip arc frame 4 and cannot be moved to the flip arc frame 4. In order to save time and reduce the time consumed in the process of loading the pipe body, it is necessary to install the flip arc frame 4 on the flip plate 7, and the flip plate 7 is connected to a flip mechanism for driving it to rotate around the center of the pipe body. The flip mechanism includes a power mechanism and a spindle. The spindle is installed on a positioning frame, and the positioning frame is inserted into a slide groove that can slide up and down relative to it.

Two pulleys 8 are provided, and the two pulleys 8 are respectively installed on the cutting adjustment shaft 6 and the main shaft. A transmission belt 9 is installed between the two pulleys 8. When the center line of the main shaft rotation is adjusted, the transmission belt 9 will move and cannot remain tightened. In order to keep it in a tightened state, a tensioning mechanism 10 for keeping the transmission belt 9 tightened is installed on the cutting base plate 1. The tensioning mechanism 10 includes a tensioning shaft 1001 and a tensioning block 1002. The outer wall of the tensioning shaft 1001 is against the outer surface of the transmission belt 9. The tensioning shaft 1001 is fixedly installed on the tensioning block 1002. The tensioning block 1002 is connected to the screw 1003 by a thread.

[0031] In a further embodiment, the main shaft is rotatably mounted on a lifting seat 11, the lifting seat 11 is connected to the output shaft of a telescopic rod 12, and the telescopic rod 12 is mounted on the cutting base plate 1;

[0032] The heights of pipe bodies of different diameters are different. In order to find the center of the pipe body, a flip center positioning assembly 13 needs to be installed on the flip plate 7. The flip center positioning assembly 13 includes a two-way cylinder 1301. The two-way cylinder 1301 is installed on a positioning frame, and bolts are installed on the positioning frame. The flip plate 7 is provided with a number of bolt holes for connecting with the bolts.
