The invention provides a cold sawing process for section steel. The equipment in the sawing area is arranged in an N+1 type: a first sawing area and a second sawing area are set, and the first sawing area includes N cold saws and a fixed Ruler baffle, the second sawing area includes a cold saw and a fixed-length baffle; the section steel is transported by the transmission mechanism, and is first sawed in the first sawing area, and the number of cut-to-length materials in the first sawing area is N multiples; when the number of remaining cut-to-length materials to be sawed is less than N, enter the second sawing area for sawing. Compared with the prior art, the section steel cold sawing process of the present invention has the following advantages: the work efficiency of the table saw and the utilization rate of the cold saw are improved, the times of sawing are reduced, and the production capacity of the cold saw is also improved.

The invention discloses a cold sawing grinding wheel with a single hypotenuse structure and a preparation method thereof, comprising a steel substrate and an annular grinding layer; on the steel substrate, the contact surface between the steel substrate and the annular grinding layer is a horizontal Z-shaped Structure; in the horizontal Z-shaped structure, the upper vertical surface is higher than the lower vertical surface; in this way, the whole grinding wheel is observed from the appearance, the grinding layer is thick on one side and thin on the other side, with the grinding wheel installation hole as the inside, the outer thickness is thicker and the inner thickness is thinner The structure makes the grinding surface thick; the grinding layer is made of resin bond and abrasive. In order to increase the holding force between the bonding agent and the substrate, the present invention adopts knurling of the outer circle, grooves on the inner side of the outer circle, and copper plating at the connection between the abrasive layer and the substrate, so as to prevent the grinding wheel from being easily detached under force. In addition, this structure can maximize the use of the grinding wheel and save costs. And its shape can be adjusted according to the shape of the processing object, which is suitable for industrial production.

The invention relates to the field of cold sawing machines, in particular to an automatic high-speed cold sawing system for superhard metal. The system comprises a machine body, a saw blade, fixing mechanisms, supporting mechanisms, an installation mechanism, a connecting mechanism, a sealing mechanism and a limiting mechanism; the supporting mechanisms are installed at the two ends of the saw blade respectively, the fixing mechanisms are installed at the two ends of each supporting mechanism, the supporting mechanisms slide on the top surface of the machine body, the two ends of workpieces make contact with the supporting mechanisms, the side walls of the workpieces are fixed, and the workpieces slide at the bottoms of the fixing mechanisms; the fixing mechanisms extrude the workpieces, the saw blade cut the workpieces between the adjacent fixing mechanisms, the top surfaces of uncut workpieces and cut workpieces are fixed by the multiple fixing mechanisms, the workpiece are preventedfrom shaking, and then the workpiece cutting faces are flush and free of burrs; the installation mechanism is arranged between the supporting mechanisms and the surface of the machine body and slidably connected with the sealing mechanism, when the supporting mechanisms slide on the top surface of the machine body, the supporting mechanisms drive the sealing mechanism to move to close the installation mechanism, and the phenomenon that workpiece chippings fall into the installation mechanism is prevented.

The invention provides a method for preparing a stainless steel cutting cold saw and a saw blade of a cold saw. The method comprises the following steps: performing stress treatment on a circular saw blade base body; controlling the welding precision of a specially-shaped tool bit; processing a low-friction-coefficient chip guiding slot, a chip breakage slot, a tipping prevention edge, a cutting edge and a low-friction-coefficient side surface on the tool bit; performing cutting edge passivation and TiAlN coating treatment after the tool bit is processed. The saw blade prepared according to the method comprises a saw blade base body, sawteeth arranged on the circumference of the saw blade base body and a mounting hole formed in the saw blade base body, a chip breakage slot is formed in a rear tool face of a sawtooth tool bit, a tipping prevention edge is cut at the intersection of the rear tool face and an upper end main side surface of the sawtooth tool bit, a cutting edge is formed at the junction part of the front tool face and the rear tool face, and a chip guiding slot is formed in the front tool face connected with the cutting edge. The saw blade has the benefits of wear resistance and heat resistance; the chip sticking resistance is improved and the service life is prolonged.

The invention relates to a synchronous cold saw cutting machine in the field of welding pipe automatic production equipment. In the synchronous cold saw cutting machine, a saw cutting motor is connected with a milling saw blade through a transmission box; two parallel main guide rails are horizontally arranged on a machine frame; main sliding blocks are arranged on the main guide rails in a matching way and fixedly arranged on the lower side of a main workbench; a driving mechanism for driving the main workbench to do linear motion is arranged on the machine frame and is in synchronous transmission connection with a main servo motor; an upright column is arranged on the main workbench and is connected with a secondary workbench through a secondary guide rail sliding block mechanism; the transmission box is fixedly arranged on the upper side of the secondary workbench; the lower side of the secondary workbench is in transmission connection with a feed motor through a ball screw mechanism; a screw nut of the ball screw mechanism is fixed with the lower side of the secondary workbench; the two ends of a screw rod of the ball screw mechanism are arranged on the upper side of the main workbench through a screw rod base; and a pipe fixture is arranged on the side of the main workbench. The synchronous cold saw cutting machine can cut off a metal pipe during the linear motion of the metal pipe, does not generate burrs on the cut, and can obviously increase the production speed of a welding pipe production line.

The invention discloses a method for installing a profile steel cold saw blade. The method is characterized by including the steps that corresponding assembly positioning holes are formed in the saw blade and a fixing disc; the saw blade and the fixing disc are relatively vertically fixed through an auxiliary device; matched positioning pins are inserted into the assembly positioning holes in the saw blade and the fixing disc, and then the saw blade and the fixing disc are relatively positioned; connecting bolts between the saw blade and the fixing bolt are installed and connected, and then installation is finished. The method for installing the profile steel cold saw blade has the advantages that installation convenience and safety of the saw blade can be improved, and labor efficiency is improved; the adopted auxiliary device assists users in installing and connecting the saw blade and the fixing disc, so that the saw blade and the fixing disc can be more quickly, conveniently and safely installed and connected with less effort.
