Sawing machine convenient to saw material segments of valve bodies

Abstract

The invention relates to a sawing machine convenient to saw material segments of valve bodies. The sawing machine comprises a saw plate, a sawtooth blade, a fixed mount and a driving mechanism, wherein the sawtooth blade comprises a sawing segment, a twisted segment and a horizontal segment, the sawing segment and the twisted segment are positioned at the lower part, and the horizontal segment is positioned at the upper part. The sawing machine further comprises an automatic sawtooth filing mechanism, a scrap removing mechanism, an oil coating mechanism and an extension workbench, wherein the automatic sawtooth filing mechanism is arranged on the fixed mount and is used for filing sawteeth passing through the horizontal segment in order; the scrap removing mechanism is positioned under the twisted segment and is close to the scrap discharging end part of the sawing segment; the oil coating mechanism is positioned behind the automatic sawtooth filing mechanism and can coat oil on the surface of the filed sawtooth blade for protection; and the extension workbench is positioned at the outer end part of a sawing platform and can support material bars extruding out the sawing platform. During sawing, the sawing machine sweeps scraps adhering to the sawtooth blade and meanwhile also ensures that the sawed end face is parallel with the sawtooth blade of the sawing segment. During no sawing, under the premise that the sawtooth blade is not need to be taken down, the sawteeth is filed and the sawtooth blade is maintained.

Description

technical field [0001] The invention belongs to the field of sawing machines, and in particular relates to a sawing machine which is convenient for sawing material sections of a valve body. Background technique [0002] As we all know, sawing machines can be divided into three types: circular sawing machines, band sawing machines, and bow sawing machines. For the valve body casting industry, it mainly cuts the entire bar into multiple sections. Obviously, circular sawing machines and bow sawing machines are not very suitable. Sawing machines are very common. [0003] At present, a band sawing machine includes a base, a sawing platform, a positioning clamp, a band saw bar, and a driving mechanism for driving the band saw bar to saw and cut material rods, wherein the chip processing of the material bar by the saw tooth bar realizes sawing into sections. [0004] However, in actual operation, it has the following defects: [0005] 1) When the sawing is completed, especially w...

AI Technical Summary

Problems solved by technology

[0005] 1) When the sawing is completed, especially when the sawtooth bar is frustrated, the sawtooth bar must be removed from the sawing machine and then filed. Therefore, the operation is very cumbersome and very inconvenient

[0006] 2) During the sawing process, it is necessary to ensure the lubrication and cooling of the sawtooth bar, so the sawtooth bar is always in a wet state. In this way, a lot of debris adheres to the sawtooth. If the residual sawdust is not removed in time, It will directly affect the efficiency and effect of sawing, and at the same time, it is easy to remain in the saw frame, resulting in very complicated and cumbersome cleaning of debris after sawing

[0007] 3) Due to the limited size of the sawing platform, once the end of the rod section to be cut extends out of the sawing platform, the sawing end will be cut to the end due to the loss of support. waste, and further grinding or flatness of the end surface is required to increase the work intensity and increase the cost
