Selection of Machine Tool for Processing L-type Crowbar Tire Wrench

The L type wrench click sound of the L-type crowbar tire wrench is reaching your required torque value. The "cat" issued by the L-shaped tire wrench is caused by its internal torque release structure. The structure of the L-shaped tire wrench is divided into three structures: a compression spring, a torque release joint, and a torque jack. At first, the required torque value should be set on the L-type tire wrench. The spring sleeve is placed on the top rod to apply pressure to the torque release joint, and the locking torque wrench starts to tighten the bolt of the L-type tire wrench.When the bolt reaches a certain torque After the distance value is used, the torque of the L-shaped tire wrench is greater than the pressure of the spring, which will produce an instantaneous disconnection effect. At the moment of the occurrence of the disconnection effect, the "kata" sound produced by the joint hitting the metal casing of the L-shaped tire wrench will be emitted. To confirm that the torque value is reached. The waste products appearing in the process are picked out by the team themselves and reviewed and disposed by inspectors.

The inspector shall conduct sampling inspection according to the prescribed inspection items. If unqualified products are found in the sampling inspection, the inspection batch should be returned to the team for self-inspection. After the unqualified products are picked out, they should be resubmitted for inspection. Inspectors supervise the production process. If the blanks do not meet the quality standards, they have the right to make adjustments. Only after they are qualified can they be mass produced. The results of the oxide scale inspection on the surface of the tire wrench are used for process control in the workshop, and are not used as a judgment of batch qualification. If there is any residual burr that exceeds the specified requirements, rework it and use a grinding wheel to remove the excessive burr. A small amount of other unqualified products shall be treated as scrap. If it is a batch of unqualified products, it shall be disposed of after being reviewed by the relevant departments.


After the inspection is completed, fill in the inspection records according to the quantity. There is no doubt that a machine tool is used for the processing of L-shaped tire wrenches. However, due to the specificity of the wrench, the choice of machine tools is also exquisite. What the editor today brings to everyone is about how to choose the machine tool when processing the L-shaped tire wrench. The fixed opening is an important part in the processing of L-shaped tire wrenches, and it is also a more complicated part, and the processing accuracy requirements are also higher. The processing of fixed openings mainly involves the processing of planes and curved surfaces and holes. Considering the economics of processing and the processing performance of machine tools, machining centers and drilling machines are used for processing. In order to facilitate processing and save processing time, more attention should be paid to the selection of blank material.Through the analysis of the processing technology of the workpiece and the characteristics of the parts, the flat wrenches can be used to complete the parts processing of the tire wrench.


The through hole used to assemble the movable opening and the blind hole used to install the pulley shaft are more troublesome to be processed on the machining center, and the edge of the end mill with the same diameter as the hole diameter generally cannot meet the hole depth requirement. The drilling machine can be used for processing, which is more convenient. End mills or face mills are generally used when machining planes in CNC machining centers. End mills are generally used for milling smaller planes, and face mills are used for milling larger planes. In order to prevent the workpiece from displacement under the action of the cutting force and keep it in the correct position during the processing, the workpiece needs to be pressed and clamped firmly. Reasonable selection of clamping methods is very important. The clamping of workpieces not only affects the processing quality, but also has a direct impact on productivity, processing costs and operational safety. For processing square holes, it is impossible to complete the processing of the right angle of the inner hole in the processing center. When processing the square hole, the right angle can be trimmed by fitters to meet the processing requirements.
