Description
Technical Field
The utility model relates to the technical field of sawing machines, in particular to a saw beam feeding device for a sawing machine.
Background
The sawing machine is mainly used for sawing various metal materials such as alloy structural steel, medium carbon steel, low alloy steel, heat-resistant die steel SKT, high alloy steel, special alloy steel, stainless steel, bearing steel, acid-resistant steel, straightening steel and the like. The conventional sawing machine is not suitable for being used in a high-speed sawing machine for high-speed sawing because the feeding speed of the sawing beam is controlled by the hydraulic oil cylinder and the feeding of the sawing beam is not stable enough due to the hydraulic fluctuation existing in hydraulic control.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a saw beam feeding device for a sawing machine, which controls a saw beam to stably feed by driving a ball screw through a servo motor, and balances the saw beam through two balance oil cylinders, so that the ball screw only bears torque and does not bear axial force.
In order to solve the problems, the utility model adopts the following technical scheme to realize:
the utility model relates to a saw beam feeding device for a sawing machine, which comprises a support arranged on the sawing machine, wherein a feeding mechanism, a guide mechanism and a balance mechanism are arranged on the support, the feeding mechanism comprises a vertically arranged ball screw, a ball nut sleeved on the ball screw and a servo motor used for driving the ball screw to rotate, the ball nut is fixedly connected with a saw beam, the guide mechanism comprises guide rails symmetrically arranged on the left side and the right side of the saw beam, the guide rails are vertically arranged, a sliding block capable of sliding along the guide rails is arranged on the guide rails, the sliding block is fixedly connected with the saw beam, the balance mechanism comprises balance assemblies symmetrically arranged on the left side and the right side of the saw beam, the balance assemblies comprise balance oil cylinders and chains, and two ends of each chain are respectively connected with the telescopic ends of the balance oil cylinders and the saw beam.
In this scheme, servo motor drive ball screw is just reversing, and ball nut reciprocates along ball screw and drives the saw roof beam lift, and the balanced cylinder receive and releases the chain in step when saw roof beam lift, reduces the axial force that ball screw received. This scheme is fed through servo motor stable control saw roof beam, because ball screw can not bear big axial force, so through the balanced hydro-cylinder balance saw roof beam weight of both sides.
Preferably, the balance assembly further comprises a guide assembly, the guide assembly comprises a guide frame, guide wheels are symmetrically arranged at the left end and the right end of the guide frame and are rotatably connected with the guide frame, the balance oil cylinder and the saw beam are located below the guide assembly, and the chain bypasses the two guide wheels.
Preferably, the guide assemblies are arranged on the top of the guide rail on the same side.
Preferably, the chain is a plate chain.
Preferably, the support is a fixed portal frame.
The utility model has the beneficial effects that: the servo motor drives the ball screw to control the saw beam to stably feed, and the two balance oil cylinders balance the saw beam, so that the ball screw only bears torque and does not bear axial force.

Detailed Description
The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.
Example (b): the saw beam feeding device for the sawing machine of the embodiment is shown in fig. 1, fig. 2 and fig. 3, and comprises a support 3 arranged on the sawing machine 1, a feeding mechanism 4, a guide mechanism 5 and a balance mechanism 6 are arranged on the support 3, the feeding mechanism 4 comprises a vertically arranged ball screw 7, a ball nut 8 sleeved on the ball screw 7 and a servo motor 9 for driving the ball screw 7 to rotate, the ball nut 8 is fixedly connected with the sawing beam 2, the guide mechanism 5 comprises guide rails 10 symmetrically arranged on the left side and the right side of the sawing beam 2, the guide rails 10 are vertically arranged, a slide block 11 capable of sliding along the guide rails 10 is arranged on the guide rails 10, the slide block 11 is fixedly connected with the sawing beam 2, the balance mechanism 6 comprises balance assemblies symmetrically arranged on the left side and the right side of the sawing beam 2, the balance assemblies comprise balance oil cylinders 12, chains 13 and guide assemblies 14, the guide assemblies 14 comprise guide frames 15, guide wheels 16 are symmetrically arranged at the left end and the right end of the guide frames 15, the guide wheel 16 is rotatably connected with the guide frame 15, the guide assembly 14 is arranged at the top of the guide rail 10 on the same side, the balance oil cylinder 12 and the saw beam 2 are both positioned below the guide assembly 14, one end of the chain 13 is connected with the telescopic end of the balance oil cylinder 12, and the other end of the chain 13 is connected with the saw beam 2 after bypassing the two guide wheels 16.
