Description

Technical Field

[0001] The utility model belongs to the technical field related to bar processing, in particular to a bar cutting machine. Background Art

[0002] Bars refer to plates and other profiles, which are round or polygonal long stick-shaped materials with a certain length. Bars are generally not castings, but raw materials for forgings. They are mostly drawn or extruded through molds, and can also be machined. Therefore, in the processing of bars, it is necessary to cut the bars, and thus the corresponding cutting machine body will be used.

[0003] However, the existing bar cutting machine cannot ensure the stability of the bar when in use. Therefore, when cutting the bar, the bar is prone to shaking and falling due to insufficient stability, so the bar cannot be cut quickly. At the same time, when cutting the bar, it does not have the function of supporting and limiting the bars of different lengths, so it is impossible to cut the bars of different lengths. To this end, we provide a bar cutting machine to solve the above problems. Utility Model Content

Specific embodiment three

[0040] See also Figure 2 On the basis of the first specific embodiment, the positioning plate 301 is slidably sleeved on the peripheral side of the positioning rod 403 through the positioning hole 302, thereby ensuring the sliding stability of the cutting machine body 3.

[0041] Specifically, a lifting bar 4 is arranged directly above the cutting machine body 3, and a cylinder 401 is fixed to the upper end surface of the lifting bar 4, and a sliding opening 402 is penetrated through the upper end surface of the lifting bar 4 located in front of the cylinder 401, and a strip plate 303 sliding through the inner position of the sliding opening 402 is fixed to the upper end surface of the cutting machine body 3, and the strip plate 303 is fixedly connected to the piston end of the cylinder 401, and positioning rods 403 are fixed between the lifting bars 4 and the bottom plate 1 on the left and right sides of the cutting machine body 3, and positioning plates 301 are fixed to the left and right parts of the surface of the cutting machine body 3, and the positioning plates 301 are slidably sleeved on the peripheral side of the positioning rod 403 through the positioning holes 302 penetrated therethrough.

[0046] The operation process of this embodiment is: when the pull plate 604 is controlled to move in the opposite direction of the sleeve 602, the pull plate 604 will drive the plug-in column 605 to move out of the inside of the circular mouth 501 through the pull rod 606, so that the plug-in column 605 will compress the spring 2 607, and the circular mouth 501 will no longer limit the plug-in column 605. At this time, when the rotating plate 6 is controlled to rotate, the rotating plate 6 will drive the sleeve 602 to rotate at the position of the circular mouth 501, so that the circular mouth 501 can be exposed. After the sleeve 602 is rotated to the same position as the circular mouth 501, the plug-in column 605 will be pushed into the circular mouth 501 by the spring 2 607, so as to abut the rod material. At the same time, when the rotating plate 6 rotates, the rotating plate 6 will rotate through the T-shaped mouth 601 with the T-shaped rod 502 as the axis. Specific embodiment five
