Description

Technical Field

[0001] The utility model relates to the technical field of material cutting machines, in particular to a material lifting device for a material cutting machine. Background Art

[0002] A cutting machine refers to a device that cuts pipes and bars according to length. It is widely used in the production and processing of various pipes and bars. During the cutting process, a lifting device is required to lift one end of the material to keep the material horizontal and avoid the material from tilting, which will cause the cut to be skewed.

[0003] Authorization announcement No. CN204094232U discloses a material lifting machine for a bar cutting machine, the material lifting machine for the bar cutting machine includes a frame, a knife seat is slidably connected to the end face of the frame, the material lifting machine includes a material lifting cylinder fixedly connected to the knife seat, the piston rod of the material lifting cylinder is axially consistent with the sliding direction of the knife seat, a material lifting slider is fixedly connected to the piston rod of the material lifting cylinder, the material lifting slider is opposite to the knife seat, and a gap for clamping the bar is formed between the two. The material lifting machine of the bar cutting machine can clamp the bar without offsetting the driving force of the knife seat.

[0004] The disadvantage of the existing bar material cutting machine is that the material is lifted by driving the oil cylinder, the main transmission rod, the upper transmission rod, the lower transmission rod and the support rod, but the material is clamped during the lifting process, which affects the material movement of the cutting machine and thus affects the material feeding efficiency. Therefore, we propose a material lifting device for the cutting machine. Summary of the invention

[0005] The main purpose of the utility model is to provide a material lifting device for a material cutting machine, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A material lifting device for a material cutting machine comprises a base plate, a main support plate and a frame sleeve, wherein the main support plate is fixed to the top of the base plate by bolts, a screw rod is installed inside the main support plate through a bearing, a sleeve is welded to one side of the main support plate, a connecting rod is provided inside the sleeve through a bearing sleeve, a secondary support plate is sleeved on the top of the main support plate, a frame sleeve is fixed to the top of the secondary support plate by bolts, and auxiliary rollers are equidistantly installed on the bottom of the frame sleeve through a mounting frame.

[0008] Furthermore, a first bevel gear is provided on the outer side of the screw rod through a flat key sleeve, and a second bevel gear is provided on one end of the connecting rod through a flat key sleeve. The second bevel gear is located inside the main support plate, and the second bevel gear is meshed with the connecting rod.

[0009] Furthermore, a thread groove is opened inside the auxiliary support plate, the top end of the screw rod is located inside the thread groove, and limit blocks are welded on both sides of the auxiliary support plate, and the limit blocks are located inside the main support plate; the setting of the limit blocks can prevent the auxiliary support plate from completely extending out of the main support plate.

[0010] Furthermore, one end of the connecting rod away from the second bevel gear is fixed with a rocker via a flat key.

[0011] Furthermore, brakeable universal wheels are equidistantly fixed by bolts at the bottom of the base plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The rotating connecting rod drives the screw to rotate through the second bevel gear and the first bevel gear. The rotation of the screw pushes the auxiliary support plate upward through the threaded groove and the frame sleeve on its top upward, thereby pushing the material upward to achieve the purpose of lifting the material. Auxiliary rollers are provided at the bottom of the frame sleeve to allow the material to move in the frame sleeve, and the movement of the material will not be affected when lifting the material.
