The present invention relates to a tool magazine of a machine tool, such as a column moving type machining center, wherein when a tool is replaced by a tool replacing part and a tool replacing part transfer part, a tool accommodated in a clamping part of a tool magazine unit is introduced or extracted from a direction perpendicular to the axis of the tool, and a flange part of the tool is directly clamped by a holding part of a replacing arm, thereby replacing the tool with the tool replacing part and the tool replacing part transfer part. In the medium-sized or large-sized machine tool having a long length in the width direction, the tool changing time can be shortened, the productivity can be improved, and the stability and reliability can be improved by minimizing collision or mechanical interference, wherein the tool magazine unit is provided on a saddle, a tool changing part is movably provided on the saddle, and the tool changing part is provided on the saddle. The tool changing and transferring part transfers the tool changing part independently from the stand column.

The invention discloses a control method for realizing high-efficiency dry running in a numerical control system. The control method is based on the surface following function of the height sensor in the numerical control system, realizes the compression of non-processing time, and makes laser processing more efficient under the premise of ensuring equipment safety. efficient. The control method includes setting a predetermined retraction height H and a predetermined distance D before the end of the dry run, which can be completed by combining the three actions in the existing laser processing into one action, that is, the processing head directly runs in dry mode. The speed quickly moves to the next processing position. During this process, the processing head first retracts to the predetermined height H at the highest speed. Before reaching the next processing point (distance D from the next processing point), it starts to descend. , which reduces the non-processing time of the equipment and greatly improves the efficiency of the equipment.

The invention discloses the application method of the cutter used for cleaning the inner wall of pipe fittings. When the central axis rotates the arc-shaped blade and contacts the solder residue and protrusions on the inner wall of the steel pipe, the interaction force on the arc-shaped blade produces a relatively large impact on itself , the stopper can provide support for the arc-shaped blade when the angle between the arc-shaped blade and the central axis reaches the maximum and also when the arc-shaped large piece is impacted the most, so as to avoid damage to the arc-shaped blade.

The invention discloses a removing mechanism for burrs in straight welded steel pipes. The removing mechanism comprises a support barrel and blade angle adjusting mechanisms. An end of the support barrel is connected with an external core rod, a plurality of rollers are arranged on the support barrel, a driving motor is arranged in the support barrel, an output end of the driving motor is connected with a cutter, the cutter comprises a center shaft, a plurality of arc-shaped blades are arranged on the center shaft, are hinged to the center shaft and are annularly arrayed and distributed on the outer wall of the center shaft, fixing plates are mounted at the upper end and the lower end of the center shaft, the arc-shaped blades are arranged between the two fixing plates, and the blade angle adjusting mechanisms are arranged among the arc-shaped blades. The removing mechanism has the advantages that the blade angle adjusting mechanisms are flexible in connection mode and simple in structure, accordingly, included angles among the arc-shaped blades and the center shaft can be quickly adjusted while the arc-shaped blades are assuredly firmly fixed, the abnormal machining time can be shortened, the efficiency can be improved when welding flux residues and protrusions on the inner walls of the steel pipes are cleaned, and the service performance of the steel pipes can be guaranteed.

The invention discloses a sheet metal part stamping device which comprises an upper die base and a lower die base. The upper die base is connected with the lower die base through a supporting rod, the lower die base is arranged on a working table of a stamping machine, a stamping head is arranged in the upper die base, a rubber block is arranged between an annular plate and a lower die fixing plate, and is arranged inside an annular ring formed by a plurality of screw rods, a sunken portion is formed in the middle of the rubber block, and is concentric with an inner hole of the annular plate, an upper surface of a stress plate and the upper surface of the annular plate are arranged on the same horizontal plane, an adjusting cylinder penetrates through the upper die base and is arranged in the through hole, the stamping head is arranged in the adjusting cylinder in a sliding mode, a fixing ring is arranged on the inner wall of the adjusting cylinder, a plurality of trapezoid-shaped grooves are formed in the fixing ring, the trapezoid-shaped grooves are radiated in the radial direction of the fixing ring, a baffle block is arranged on the trapezoid-shaped grooves, protrusions are connected with the lower portion of the baffle block, the protrusions are arranged in the trapezoid-shaped grooves in a sliding mode, the baffle block is connected with the wall of the adjusting cylinder through a torsion spring, and in the working process, the torsion spring is in the compression state.
