Method for removing lock core burrs

Abstract

The invention relates to the technical field of manufacturing of lock cores, in particular to a method for removing lock core burrs. The method comprises the following steps of: A, allowing a steel wire to penetrate through a hole of a lock core; B, straightening the steel wire and connecting the two ends of the steel wire to a fixing frame respectively; C, fixedly arranging the fixing frame on vibrating equipment; D, starting the vibrating equipment to start vibrating for 5 to 30 minutes; and E, closing the vibrating equipment, disassembling the steel wire from the fixing frame and taking the lock core out. The method for removing the lock core burrs has a simple process, low machining difficulty, and high operability, economic benefit and practicability, and the lock core burrs can be removed on a large scale.

Description

technical field [0001] The invention relates to the technical field of lock core manufacturing, in particular to a method for removing the drape of a lock core. Background technique [0002] Porous die-casting parts, such as various lock cylinders, are indispensable workpieces in life now. During the die-casting process, because there is inevitably a gap of 1 to 2 wires between the movable die and the fixed die, the metal fluid will flow into the die-casting part. The gap forms redundant flaky corners, commonly known as the front. Usually, the cutting edge of the die-casting part is realized by manual milling and filing, but for a porous workpiece such as a lock cylinder, the hole is small and deep, it is difficult to mill and file by hand, and it is also very labor-intensive and difficult to large-scale Production. [0003] At present, there is a way to achieve large-scale removal of the front of the porous workpiece, that is, the method of sandblasting, but this method r...

Usually, the cutting edge of the die-casting part is realized by manual milling and filing, but for a porous workpiece such as a lock cylinder, the hole is small and deep, it is difficult to mill and file by hand, and it is also very labor-intensive and difficult to large-scale Production

[0003] At present, there is a way to achieve large-scale removal of the front of the porous workpiece, that is, the method of sandblasting, but this method requires the temperature of the workpiece to be lowered below zero, which will make the front part brittle. The brittle front can be removed during the process. The disadvantage of this method is that due to the constraints of the volume of the low-temperature cavity, the number of each processing is limited, and the processing time is relatively long. The difficulty of the environment is relatively high, which makes the cost of this process very high
