Description

A horizontal band saw cutting machine

Technical field:

The utility model relates to the technical field of band saw machines, in particular to a horizontal slice band saw cutting machine.

Background technique:

At present, frame saws, band saws, multi-axis horizontal saws and horizontal band saws are mostly used in the market to process plates. Among them, frame saws with high precision and high cost, Most of them are imported from abroad, and because the saw blade is short during processing, the saw blade reciprocates up and down at high speed to cut, the cutting distance of the saw blade is small, it is difficult to effectively discharge the sawdust, and it is easy to cause friction between the saw blade and wood chips and materials, thermal deformation, and the replacement rate of the saw blade is quite high. It also affects the quality of the processed thin plate. The sawn surface of the processed material needs to be sanded with a certain thickness to a certain thickness, and the material loss is large; although the band saw machine is cheap, the sawn surface of the processed material is very uneven, and the material loss The biggest, the production efficiency is too low, and there are high requirements for the sawing technology and proficiency of the operators; Fast, but the material loss is also large, the design of the equipment is more complicated and difficult to debug, and the failure rate of the equipment is high. In order to ensure the strength of the saw blade (to avoid the deformation of the saw blade when sawing materials at high speed), in addition to the saw blade must have a certain thickness. In order to prevent the saw blade from heating and deforming due to friction and heat when the saw blade rotates at high speed to cut materials, a refrigeration system is required to force the saw blade to cool down. The loss of the saw blade is also large during the processing process, and the frequent replacement of the saw blade affects production. At the same time, the replacement and debugging of the saw blade is also relatively complicated. Once the material enters the processing and conveying system, the material cannot be screened reasonably, and defects such as spots, edges, and decay inside the material cannot be deleted. Structural principles, the processing range of the multi-axis horizontal saw sectioning machine (four-sided planing horizontal multi-piece sectioning machine) cannot directly process large square materials, it needs to be sawed into small thick plates and then processed after four-sided planing and preparation, material loss Large; although the production speed of the horizontal band saw machine is very fast, there are great contradictions in the design principle of the machine. It is driven by a belt to convey materials, and the operation of the saw blade is sawed above the conveyor belt, so that it cannot effectively exert a large pressure. Flatten the deformed material on the working table conveyed by the belt for sawing, and the finished material will inevitably have uneven thickness. After the saw blade is sawed, the upper material and the lower material behind the saw cut will tightly clamp the saw blade and the conveyor belt, causing friction between the saw blade and the material to generate heat and deformation, and the wear and tear of the saw blade is quite high. The processing quality of the product is high, and the material loss is also very large.

Utility model content:

The purpose of the utility model is to provide an improved horizontal band saw cutting machine, which can overcome the disadvantages of high cost, large material loss and complicated equipment debugging in the prior art.

In order to achieve the above object, the technical solution of the utility model is: a horizontal band saw cutting machine, which mainly includes a base and front and rear workbenches arranged on the base, and is characterized in that: the front and rear worktables A cutting device is embedded between them, and there are two saw wheels arranged at the same horizontal position in the cutting device. The band saw blade connects the two saw wheels. The front and rear workbenches on the side are provided with slidable front and rear adjustment lifts, and the front and rear lifters are respectively equipped with a workbench before feeding and a workbench after discharge.

When in use, the processed material of the horizontal band saw machine of the present utility model is pushed into the workbench before feeding by hand or by a material feeder, and the processed material can be smoothly attached to the worktable in a large area for sawing, which can ensure the Precise processing of materials, the band saw blade is set horizontally on the saw wheel, the working surface of the band saw blade is kept at the same level as the working surface after discharge, the band saw blade cuts with the rotation of the saw wheel, and the material can be separated from the band saw blade The joint action of the steel plate spacer reduces the friction between the band saw blade and the material, making the band saw blade less prone to thermal deformation. Therefore, when the material is sawed, the saw road will not be enlarged, and the loss of the material and the saw blade can be reduced at the same time. The device is embedded between the front and rear worktables, which makes the whole machine compact and practical, saves the space on the worktable, and is convenient for manual processing of small batches and special specifications of plates. The saw blade protection cover is U-shaped, and the working part of the saw blade is exposed. Outside the saw blade guard, the rest of the saw blade is arranged inside the saw blade guard, so that the height of the processed material is not limited. At the same time, the height of the front and rear adjustable lifting tables on both sides of the cutting device can be adjusted freely, and it is equipped with a horizontally movable workbench before feeding and a workbench after discharging, which can be used for different saw blade widths and workpiece hardness. Adjust the most stable and high processing accuracy and speed. During sawing, the conveying pressure wheel can also effectively control the up and down swing of the sawn timber, ensuring the consistency of the sawn timber thickness and the smoothness of the sawing section. Improve the use of safe processing split saw quality to reduce the loss rate of materials and the processing technology and labor requirements for professionals, and the equipment has a simple structure, convenient debugging and installation, and the equipment manufacturing cost is low.
