Description

Pipe section equally-divided sawing blanking tool

Technical Field

The utility model belongs to the technical field of machining, and particularly relates to a sawing and blanking tool for equally dividing the section of a pipe material, which is used for equally dividing, breaking and blanking the leftover bits and pieces of various thick-wall pipe materials.

Background

The thick-wall pipe material is a common raw material for the hydraulic support, is largely adopted in the production process of various supports, and the quantity of the produced leftover materials is very large, so that the surplus heads are seriously wasted according to waste treatment. How to recycle the residual material heads has good practical significance for factories.

The quantity of stub bars remained after various pipe materials are discharged is considerable, but the lengths are different, the specifications are different, and the stub bars are difficult to directly process and utilize in batch organization. The small forgings such as T80 and T100 commonly used in the hydraulic support have the characteristics of small weight, flexible material preparation and high standardization level. After the waste pipe material is divided along the section, as shown in fig. 1, the waste pipe material is divided into four parts, and the fan-shaped ring can be changed into a thin bar by forging deformation, so that the waste pipe material is used for producing small forgings. The tube stock is axially cut into equally divided sections to form the necessary steps.

At present, sawing and blanking are the most common blanking means for civil products production, and the horizontal band saw machine tools are most common. The device is only suitable for transversely cutting off longer pipe bars, and is not suitable for axially equally dividing bars into sectors. The pipe material cannot be clamped after being cut into semicircle, workers can only use various cushion blocks to assist in clamping, and can only clamp and saw 1 piece at a time. Because the specification of the pipe material is complicated, a plurality of cushion blocks are needed to be prepared for completing sawing.

Therefore, the following disadvantages exist when the horizontal band sawing machine is adopted to quarter or eighth quarter thick-wall pipe materials in the prior art:

(1) the existing sawing machine is only suitable for transversely cutting long pipe and rod materials, is not suitable for axially splitting bar materials and the like, and has no equipment or tool capable of meeting the sawing requirement on the market.

(2) The auxiliary clamping of various cushion blocks can be only used, and only 1 saw cutting part can be clamped at a time, so that the efficiency is low.

(3) After the pipe material is broken and disassembled into four equal parts, the blank is easy to fall from the gap of the sawing machine roller, the operation is inconvenient, and the safety risk exists.

(4) The equal division precision is not enough, and the size of the blanks is different after breaking, which is not beneficial to the subsequent forging.

The existing method has high labor intensity and low working efficiency, and has potential safety hazard. Therefore, it is necessary to develop an adjustable sawing tool for pipe materials, which is convenient to install, and the sawing tool is applied to the existing horizontal band saw machine tool, so that the sawing tool becomes a key link in the waste utilization operation.
