In machinery manufacturing, heavy‑duty equipment, energy & power, aerospace and other industries, large‑size castings, molds, steel plates and pipe fittings are widely encountered. When workpieces grow larger, they can no longer fit on conventional hardness testers. When workpieces become heavy, manual handling poses safety risks and reduces work efficiency. As irregular‑shaped components become more prevalent, fixed‑station benchtop hardness testing has turned into a challenging problem.
How can we solve hardness testing for large‑scale workpieces? The gate‑type Brinell hardness tester manufactured by Laizhou Laihua is specially engineered to meet hardness‑testing requirements for large‑dimension, heavy‑weight and hard‑to‑position workpieces.
The gate‑type Rockwell hardness tester from Laizhou Laihua is a large‑scale automatic hardness‑testing device integrated with a Rockwell hardness‑measuring unit, featuring a gate frame structure, automatic X‑Y‑Z‑axis movement, and closed‑loop control via high‑precision force‑value sensors.
Boasting an extra‑large testing stroke and heavy‑load capacity, it supports automatic positioning, automatic measurement and data management. It is widely used for hardness inspection of large castings, weldments, molds, rolls, pipe fittings, machine‑tool beds and other components.
This gate‑style hardness tester has the following main features:
1.gate‑type structure with extra‑large testing space Built with a robust gate frame, the measuring head spans over the large‑size worktable to enable wide‑range, multi‑point hardness testing on the top surface of workpieces. Compared with traditional benchtop hardness testers, it delivers a longer testing stroke and more flexible workpiece clamping, solving the common problem of large‑sized workpieces that “cannot fit inside or be reached for measurement”.
2.High‑rigidity Worktable with Heavy‑load Capacity Equipped with a thickened cast‑iron platform, its load‑bearing capacity far exceeds that of ordinary hardness testers. Heavy castings, molds and large modules can be placed directly on it without frequent hoisting and transportation, which improves testing safety and efficiency.
3.Automatic X‑Y‑Z Positioning Servo‑controlled on X/Y/Z three‑axis, it supports multi‑point automatic measurement, path planning and batch testing. No repeated manual adjustment of workpiece position is required during the whole testing process, greatly reducing human error and labor intensity.
4.One‑click Automatic Rockwell Hardness Measurement Loading, dwell holding, unloading and reading‑out are completed automatically in compliance with Rockwell hardness testing standards, delivering stable and reliable measurement results. Equipped with a digital display system and software interface, the instrument automatically records, stores and exports test data to facilitate quality traceability.
5.Customizable Expansion for On‑line Testing Requirements Functions including automatic loading‑unloading, on‑line inspection, grading judgment and data upload to MES system can be customized according to customers’ production‑line cycle time, workpiece dimensions and testing‑process requirements. It enables seamless expansion of hardness testing solutions from laboratory‑based operation to intelligent production‑lines.
Simple and convenient operation procedure:
1.Select the required test scale.
2.Adjust the X‑axis and Y‑axis via the operation remote‑controller to align the indenter precisely with the testing position on the workpiece.
3.Press the Start button on the remote‑controller, and the equipment will automatically complete the full‑cycle process of loading, dwell, unloading .
4.Upon completion of the test cycle, the hardness value will be displayed directly on the screen.
