Description

Limiting device of metal band sawing machine

Technical Field

The utility model relates to the field of diesel engines, in particular to a limiting device of a metal band sawing machine.

Background

The raw material of the cylinder sleeve of the diesel engine is a seamless steel pipe, and a metal band sawing machine is used for sawing a 7-9 m pipe into a workpiece blank with a certain length in the blanking process, and then the workpiece is machined. Under the prior art scheme, the operation steps of sawing machine blanking are as follows: 1) The operator presses the sawing machine fast forward button, and the saw blade drops down quickly. The falling speed of the saw blade is set by the sawing machine and cannot be adjusted; 2) And the operator visually observes and judges that the saw blade descends to a proper position by feeling, and then releases the button to stop the saw blade from descending. If the stopping position is not proper, the fast forward button needs to be continuously pressed, the saw blade descends again, and each cylinder sleeve is repeatedly clicked for a plurality of times until the cylinder sleeve is proper. 3) And starting a sawing button to start blanking processing. In step 2), the blade stop position is too high, meaning that a blank stroke is needed to be sawn, resulting in waste of processing time, and the saw blade is easy to collide with raw materials in the repeated adjustment process of reducing the saw blade, thereby damaging the saw blade.

Detailed Description

The utility model is further illustrated by the following examples:

as shown in fig. 1, the limiting device of the metal band sawing machine comprises a saw blade 1 connected with a sawing control system and a sawing machine 2 for driving the saw blade 1 to move, wherein a fixed block 3 is fixedly connected to the side edge of the sawing machine 2, a micro switch 4 is fixedly arranged above the sawing machine 2, and the micro switch 4 is an outsourcing piece. The micro switch 4 is connected with the sawing machine control system in a wiring way, the side edge of the fixed block 3 is fixedly connected with the shaft sleeve 5, and the shaft sleeve 5 is fixedly welded with the fixed block 3 and then fixed on the sawing machine 2 through bolts.

The probe rod 6 is vertically movably arranged in the shaft sleeve 5, the oil bowl 10 is arranged above the shaft sleeve 5, the felt pad is arranged in the oil bowl 10, lubricating oil is added to the felt pad in the oil bowl 10, grease on the probe rod 6 can be kept constantly, and the probe rod 6 is easy and free from clamping stagnation in the up-and-down movement process.
