Forging length size online quantifying inspection tool

Abstract

The invention discloses a forging length size online quantifying inspection tool which consists of a slide rule, a fixed rule and screws. Both the slide rule and the fixed rule are L-shaped rod parts; matched measuring jaws of the two rod parts have equal lengths; a rod body of the fixed rule is longer than the long edge of the slide rule; the long edge of the slide rule is formed by a round pipe; the cylindrical rod body of the fixed rule is sleeved with the round pipe of the slide rule; the front side of the cylindrical rod body of the fixed rule is smoothened, the center of the plane of the cylindrical rod body of the fixed rule is provided with an axle groove; the planes at both sides of the groove are provided with scales; and the upper front side of the pipe wall of the long edge of the slide rule is provided with at least two radially arranged screws and the screwed screws are inserted into the groove of the fixed rule to form a guiding and locking structure for the fixed rule. Although a forging has a higher temperature in the forging process, the forging can be conveniently and rapidly subjected to measurement by applying the forging length size online quantifying inspection tool, the forging is clamped by two measuring jaws and the displacement of the slide rule relative to the fixed rule is defined by the scales. Measurement is quantifying measurement, thus, the real-time size of the forging can be objectively obtained and an operator can implement forging according to the actually measured size in a targeted manner.

Description

technical field [0001] The invention relates to a length measuring instrument, in particular, the invention relates to a checking instrument for quantitatively measuring the length of forgings on-line. Background technique [0002] The rolling ring section on the offshore oil pipe joint is thicker than the main body, and the rolling ring is a thick-walled ring, which is usually formed by forging. During the free forging process, it is necessary to frequently check the size of the forging to guide the forging amount in the later stage. Due to the large size, heavy weight and high temperature of the forging, the existing general-purpose measuring tools are not suitable for measurement under such harsh conditions. The production line of this industry generally uses fixed-length pallet inspection. Although this type of qualitative inspection equipment can be used in actual production, frequent inspections consume a lot of man-hours. Non-quantitative measurements not only reduce ...

AI Technical Summary

Problems solved by technology

The production line of this industry generally uses fixed-length pallet testing. Although this type of qualitative testing equipment can be used in actual production, frequent testing consumes a lot of man-hours. Non-quantitative measurement not only reduces forging efficiency, but also increases the amount of subsequent machining.
