Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a channel steel and screw rod cutting machine. Background Art

[0002] Channel steel is a kind of steel with high strength, corrosion resistance and reliability, playing an irreplaceable role in the fields of building structure, mechanical equipment and vehicle manufacturing. Common channel steel is generally a long steel strip with a grooved cross section, which has high strength, corrosion resistance and reliability. The cross-section of the channel steel profile is a groove, which enables the channel steel to withstand large loads and stresses, and has good stability and shock resistance. Screw rod is a rod-shaped object with threads, which is mainly used to convert rotary motion into rotational motion, such as used in machine tools, automobiles and other mechanical devices.

[0003] During use, considering production costs and steel transportation, channel steel and screw rods usually need to be transported to the site of use and then cut to an appropriate length according to actual needs. Currently, most of the equipment used on the market is abrasive wheel cutters, which cut steel by high-speed rotation of the grinding wheel. Abrasive wheel cutters are generally large in size and weight, and are often accompanied by sparks, dust and noise during the steel cutting process. They are not conducive to working in sites with control requirements, and even have the risk of fire hazards. They are also prone to affect the production quality of products due to severe shaking. At the same time, abrasive wheel cutters consume abrasive wheel cutting discs, and residual slag and foam will be generated when cutting products. There are deformation and discoloration of steel cuts, and there are a large number of sharp burrs. The loss of resources also reduces the quality of the product. Utility Model Content

[0034] like Figure 1-Figure 3 As shown, the present application provides an embodiment of a channel steel and screw rod cutting machine, which includes a mold frame 100, a mold 200 and a hydraulic press 300. The mold frame 100 includes a mold frame top plate 130, a column 120 and a mold frame bottom plate 110. One end of the column 120 is bolted and fixedly connected to the mold frame bottom plate 110, and the other end is bolted and fixedly connected to the mold frame top plate 130. The mold frame top plate 130 and the mold frame bottom plate 110 are both rectangular plates. There are four columns 120, and the four columns 120 are respectively fixed to the four corners of the mold frame top plate 130 and the mold frame bottom plate 110. The mold 200 includes an upper mold 220 and a lower mold 210, and the lower mold 210 is fixed on the mold frame bottom plate 110; both the upper mold 220 and the lower mold 210 are provided with a cutting hole 230, and a slide groove is provided on the lower mold 210 in a direction perpendicular to the cutting hole 230, and the upper mold 220 is nested in the slide groove and can move up and down along the slide groove; the hydraulic press 300 includes a hydraulic body and a hydraulic rod 320, the hydraulic body is fixed above the mold frame top plate 130, the hydraulic rod 320 passes through the mold frame top plate 130 and is connected to the top of the upper mold 220, and the hydraulic rod 320 is used to drive the upper mold 220 to cut the channel steel downward.

[0035] The hydraulic press 300 is generally an electric hydraulic press 300, which can be connected to a common 220V voltage power supply. When the utility model cuts the channel steel, it is necessary to insert the channel steel or the screw rod into the cutting hole 230, measure the length of the required channel steel, the screw rod or the screw rod, and connect the power supply of the hydraulic press 300. The hydraulic rod 320 of the hydraulic press 300 drives the upper mold 220 to slide downward, and finally the upper mold 220 and the lower mold 210 in the mold 200 are in the same position. Figure 5The state shown in the figure is realized, thereby realizing the dislocation cutting of the channel steel. In this embodiment, hydraulic pressure is used as the driving source, and the hydraulic rod 320 is used to give the upper mold 220 an ultra-high pressure, thereby realizing the dislocation cutting of the channel steel. No sparks or dust are generated during the cutting process, the product incision deformation is small, there is no temperature difference discoloration, and the sharp cutting edge is guaranteed, so as to ensure the product quality. In addition, the structure design of the mold 200 of the present application is ingenious, simple and light, and easy to assemble and use. In addition, the high-pressure cutting has low noise and slight vibration, which is suitable for more production environments, environmentally friendly and safe.

[0036] like Figure 4 As shown, in this embodiment, the formwork top plate 130, the column 120 and the formwork bottom plate 110 are respectively connected by bolts, the structure is light, the bolt connection is more convenient for disassembly and transportation, and the assembly is simple and convenient.

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, a group of upper molds 220 and lower molds 210 are provided with a plurality of cutting holes 230, one cutting hole 230 is in the shape of a channel steel cross section, and the other two cutting holes 230 are in the shape of a circular screw cross section. A group of molds 200 can be used for cutting channel steel profiles and screws and lead screws of different specifications, respectively. The specifications of the two circular cutting holes 230 can be 12M and 16M respectively. In particular, a screw or lead screw with a specification of 10M can also be hydraulically sheared in a 12M cutting hole 230, which is convenient for cutting and improves the application range of the mold 200. Reducing the number of molds 200 helps to reduce operating costs. In other embodiments, the shape, number and position of the cutting holes 230 on the mold 200 can be adaptively adjusted according to actual needs.

[0038] In one embodiment, the lower mold 210 is fixedly connected to the mold frame bottom plate 110 by bolts, that is, the mold 200 on the mold frame 100 can be replaced as needed, and only different molds 200 need to be replaced to cut channel steel profiles of different specifications and models. In addition, the mold 200 fixed by bolts is easy to disassemble, making the inspection and replacement of the mold 200 more convenient, further improving the applicability of the present application, and making it more convenient to disassemble, assemble, carry and transport. In addition, the mold 200 is simple and durable, and is easy to produce, replace and maintain.

[0039] like Figure 1 and Figure 6As shown, in this embodiment, a mold clamp 400 is also included. A locking screw hole 2201 is provided at the top of the upper mold 220. The lower end of the mold clamp 400 is screwed into the locking screw hole 2201, and the upper end is connected to the hydraulic rod 320. The arrangement of the locking screw hole 2201 and the mold clamp 400 makes the connection between the upper mold 220 and the hydraulic rod 320 more stable, facilitates stable cutting, ensures the stability of the cut, and controls the product quality. At the same time, it is convenient to replace the mold 200 connected to the hydraulic rod 320.

[0040] In one embodiment, the moving distance of the upper die 220 in the slide groove is greater than the thickness of the channel steel or the diameter of the screw rod inserted into the cutting hole 230, thereby ensuring that the channel steel or the screw rod can be completely cut off.

[0041] In particular, on the mold 200, the upper cutting holes 230 of the upper mold 220 and the lower mold 210 are left straight and cut 1.5 degrees, so as to ensure that the cut edge surface has a good cutting effect and the cut shape remains unchanged.

[0042] In one embodiment, the hardness of the upper die 220 and the lower die 210 is more than 10 degrees higher than that of the channel steel material. The hardness of the A3 steel material commonly used for the channel steel is 40 degrees. The hardness of the mold 200 must be greater than the hardness of the channel steel in order to extend the service life of the mold 200 as much as possible while ensuring the cutting quality. In this embodiment, the upper die 220 and the lower die 210 are both made of molybdenum-vanadium steel, which is a new type of alloy steel with a molecular formula of Cr7MoV. By effectively controlling harmful inclusions such as sulfur and phosphorus in steel, the hardness and toughness of molybdenum-vanadium steel reach the highest international standards. The characteristics are high carbon content, which greatly improves the hardness of the mold 200, and the chromium, molybdenum, and vanadium can effectively control the brittleness of the mold 200 and improve the toughness, and finally make the comprehensive performance of the mold 200 reach a new height.
