Inclination detection tool for forging sawing or shearing end face of blank
Technical Field
The utility model relates to an inclination detection tool, in particular to an inclination detection tool for forging sawing or shearing an end face of a blank.
Background
Forging and blanking is a machining process with high yield requirement and high labor intensity in machining. The blanking in the forging workshop mainly adopts a method of sawing by a band sawing machine and shearing by a shearing machine. During sawing and shearing, the end face of a cut blank is inclined due to abrasion and tensioning relaxation of a saw blade of a sawing machine or improper blade clearance of the shearing machine, blade abrasion, block abrasion and the like, the inclination angle is variable, and forging defects are caused by the fact that the inclination angle is too large. The inclination of the end face of the cut blank is regulated by industry technical regulations, and the end face inclination angle is measured and is qualified within a certain range, namely, the inclination angle is less than or equal to X degrees, namely, 0~X degrees. In the forging process, a universal angle ruler is generally adopted for measuring the inclination angle of the end face, and an accurate angle value is measured. But the universal angle ruler is used for finely detecting a flat surface, and has the advantages of higher cost, high use and operation requirements, easy collision and damage and time consumption due to difficult detection caused by operation. The forging blanking is coarser machining, the dynamic change of the blank inclination angle in the mass blanking production needs to be measured at any time, and in view of the use limitation of the universal angle ruler, a new detection tool is needed.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
After sawing or shearing round bar, the cut end surface has a certain inclination, the inclination is controlled by the inclination angle, and the inclination angle alpha=the measuring angle a-90 degrees. The inclination angle is not fixed and dynamically changed in the production process, and the inclination angle needs to be effectively controlled. In the prior art, a universal angle ruler is usually used, and the universal angle ruler is fixed and movable at one side, so that the use is complicated and the efficiency is low.

The upper end face of the riser 12 is connected with the bottom face of the transverse plate 11, so that the transverse plate 11 and the riser 12 form an L-shaped ruler, the rule data of the inclination angle obtained according to actual measurement in the embodiment is 1 degrees, the limit data of the inclination angle is 1.5 degrees, therefore, the detection angles between the reference surface 1 and the comparison surface 2 of the two detection tools are 91 degrees and 91.5 degrees respectively in the embodiment, the 91.5 degrees correspond to the section within 1.5 degrees of the detection inclination angle and are 1-grade clamping plates used for measuring and finding whether the inclination angle is larger than 1.5 degrees or not, the 91 degrees correspond to the detection angle 1 degrees and are 2-grade clamping plates used for finding whether the inclination angle is smaller than 1 degrees or not as shown in fig. 2 (b). One end of the handle 13 is connected to the outside of the corner of the L-shaped ruler. The handle 13 is provided with a through hole 14 for hanging. The diameter of the through hole 14 is 5 mm. The transverse plate 11, the vertical plate 12 or the handle 13 is provided with an angle value mark 15, and in the embodiment, the angle value mark 15 is printed with an angle between the reference surface 1 and the comparison surface 2.
