On-line hardness measuring device and method for manhole cover production process

Abstract

The invention discloses an on-line hardness measuring device and a method thereof in the production process of manhole cover, which comprises a production mechanism and a measuring mechanism. Then, the cooled manhole cover is moved from left to right under the drive of the conveyor belt. The moving process of the manhole cover can be realized without manual handling, which saves manpower. Different production batches, The initial differentiation process of manhole covers of different quality reduces the range of data measured by the same Rockwell hardness tester, realizes segmental measurement of manhole covers, facilitates data statistics, and can choose to install one or more sets of arc interceptors according to actual production needs Each set of arc-shaped interceptors corresponds to a set of measuring institutions, which improves test efficiency, sorts out unqualified products in advance, and reduces the rate of defective products. HRSS‑150 digital display double Rockwell hardness tester is used to test faster. , better practicality.

Description

technical field [0001] The invention relates to the technical field of manhole cover production, in particular to an online hardness measurement device and method during the production process of manhole covers. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection well, and the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well. Mainly, in the production process of manhole covers, different batches of products with different weights will be produced according to the different uses of manhole covers. For performance testing, the test equipment is not synchronized with the production line. Usually, the finished manhole cover is manually transpo...

Problems solved by technology

[0003] The object of the present invention is to provide an online hardness measuring device and method in the production process of manhole covers. By connecting the conveyor belt with the finished product delivery device on the manhole cover production line, the moving process of manhole covers can be realized without manual handling, saving Manpower; through the setting of different groups of arc-shaped interceptors, the preliminary distinction process of manhole covers of different production batches and different qualities can be realized, the data range of the same Rockwell hardness tester can be reduced, and the segmental measurement of manhole covers can be realized, which is convenient for data Statistics; one or more sets of arc-shaped interceptors can be installed according to actual production needs, and each set of arc-shaped interceptors corresponds to a set of measurement institutions to improve test efficiency, sort out unqualified products in advance, improve product quality, and reduce Defective rate, better practicability, to solve the problem of manually transporting the finished manhole cover to the testing equipment proposed in the above background technology, which is time-consuming and laborious, and seriously reduces the testing efficiency, and the weight difference between different batches of finished manhole covers Larger, the gap between the test values ​​is also larger, it is not convenient for the staff to record, and the problem of poor practicability
