Description

Technical Field

[0001] This utility model belongs to the field of steel testing technology, specifically a device for detecting the difference in rolling mill diameter of steel. Background Technology

[0002] The temperature-controlled rolling measures used in the production of steel products such as coiled rebar and wire rod mainly involve low-temperature initial rolling, controlling the temperature before entering the finishing mill, and controlling the temperature during the finishing stage and cooling after wire drawing through water cooling between the finishing mill stands, thereby controlling the product performance. However, due to the temperature difference between the beginning and end of the heating furnace and the difference between lapped and non-lapped sections of the coiled rebar at the Steyrmo roller conveyor, there is a significant variation in the performance of the same coil, which in turn affects the strength and toughness of the rebar, resulting in differences in the physical properties of the same coil. Currently, in order to test the performance of coiled rebar and wire rod, they are cut into multiple (usually 6) equidistant steel bars for tensile performance testing.

[0003] The applicant found in actual use that the current testing is done on a single basis, which takes a long time and affects the testing efficiency. In addition, each steel bar is tested separately, and it is difficult to ensure the consistency of the machine's data during the testing process, which may result in small errors after testing. There is still room for improvement. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] Reference Figure 1-3 A steel rolling mill same-circle difference detection device includes a base 1 and a detection frame 4. An upper clamping assembly 6 and a lower clamping assembly 3 are respectively mounted on the base 1 and the detection frame 4. The upper clamping assembly 6 and the lower clamping assembly 3 have identical structures and are arranged coaxially opposite each other. Multiple clamping mechanisms for clamping wire are equidistantly arranged circumferentially at their opposite ends for simultaneously detecting multiple wires. The upper clamping assembly 6 and the lower clamping assembly 3 are designed to simultaneously clamp multiple steel bars. During detection, multiple sheared steel bars can be simultaneously detected, improving overall detection efficiency. Simultaneous detection ensures consistency of machine tensile pressure and other conditions, improving the accuracy of same-circle physical property detection of steel. Preferably, there are 6 clamping mechanisms; in other embodiments, 7 or even more can be designed.

[0020] Furthermore, a hydraulic pusher 5 is installed on the testing frame 4. The telescopic end of the hydraulic pusher 5 is connected to a mounting plate, which is connected to the pusher 2. When performing tensile performance testing, the hydraulic pusher 5 retracts, causing the upper clamping assembly 6 to move upward. During the movement, the steel bar is stretched. Based on the fracture sequence of the steel bar under different forces, the difference in physical properties of the same ring can be known. The hydraulic pusher 5 is preferably a hydraulic cylinder.

[0021] Furthermore, both the upper clamping assembly 6 and the lower clamping assembly 3 include a housing 31, an adjusting rod 36, and multiple clamping plates 32. The housing 31 protrudes upward to form a boss, and an adjusting cavity 34 is formed between the housing 31 and the boss. The adjusting rod 36 is placed in the adjusting cavity 34 and can move up and down along the adjusting cavity 34. Pushing members 2 are respectively provided on the base 1 and the detection frame 4. The telescopic end of the pushing member 2 extends into the adjusting cavity 34 and is connected to the adjusting rod 36. The pushing member 2 can drive the adjusting rod 36 to move up and down. The clamping mechanism includes an outer clamping plate 32 and an inner clamping plate 33 arranged opposite to each other. The outer clamping plate 32 is fixed on the housing 31. A stop rod 38 is provided at the end of the inner clamping plate 33 away from the outer clamping plate 32. A stop rod 38 is opened on the boss to meet the requirements of the stop rod. The rod 38 passes through a through hole, and a retaining ring protrudes from the outer wall of the retaining rod 38. A spring 35 is fitted onto the retaining rod 38 between the inner wall of the protrusion and the retaining ring. One end of the adjusting rod 36 is integrally provided with a frustum 37. The inner end face of the retaining rod 38 is provided with an inclined surface with the same slope as the frustum 37. When fixing the steel bar, the steel bar can be placed between the outer clamping plate 32 and the inner clamping plate 33 at the same time. Then, the pushing member 2 drives the adjusting rod 36 to move upward. During the movement, multiple retaining rods 38 are driven to move the inner clamping plate 33 outward in sync, which can realize the synchronous clamping operation of multiple steel bars. When disassembling, the pushing member 2 retracts. Under the rebound force of the spring 35, the retaining rods 38 and the inner clamping plate 33 can be reset synchronously, so that the disassembly operation can be performed synchronously. The pushing member 2 is preferably a hydraulic cylinder.

[0022] Among them, the opposite ends of the outer clamping plate 32 and / or the inner clamping plate 33 are recessed inward to form an arc-shaped groove. The arc-shaped groove is designed to assist in positioning the steel bar when installing it. The opposite ends of the outer clamping plate 32 and / or the inner clamping plate 33 are provided with anti-slip texture (not shown in the figure).

[0023] Furthermore, the base 1 is equipped with a control panel 7 and a hydraulic system (not shown in the figure). The hydraulic system is a hydraulic pump station, which is connected to the hydraulic pusher 5 and the pusher 2. The control panel 7 is equipped with a display screen, operation buttons, etc.
