Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled plate and strip steel measuring devices, in particular to a device for measuring the size of a hot-rolled strip steel intermediate billet. Background Art

[0002] The model setting of the hot-rolled strip mill needs to provide accurate intermediate billet dimensions, including wedge shape, thickness, width and convexity. The more accurate the dimensions are, the more favorable it is for the model setting of the finishing mill, and the more stable the control of the finishing mill is, the more qualified products can be produced. Therefore, technicians are required to regularly measure the dimensions of the intermediate billet scrap produced and calibrate the size of the intermediate billet output for rough rolling. Since the thickness of the intermediate billet is between 32-60mm, the surface oxide scale is thicker in the cold state and the cross section is rougher, a special measuring device is required for accurate measurement.

[0003] Common hot-rolled strip intermediate billet size measuring devices are mostly used through various micrometers, vernier calipers and other precise measuring devices. Common micrometers, vernier calipers and other devices have good operating effects when measuring, but there are still some problems:

[0004] 1. It is very inconvenient to measure directly on the slab with ordinary micrometer and vernier caliper, and it is difficult to measure accurately.

[0005] 2. Common measuring devices are prone to deviations when in use. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Embodiment 1

[0031] See also Figure 1-5The utility model provides a device for measuring the size of an intermediate billet of hot-rolled strip steel, comprising a first support frame 1, an outer caliper 2 and a second support frame 3. The outer caliper 2 is rotatably connected to one side of the first support frame 1, and the inner caliper 5 is rotatably connected to the other side of the first support frame 1. The second support frame 3 is arranged on the outer side of the outer caliper 2, and auxiliary measuring structures 6 are arranged on both sides of the second support frame 3. The auxiliary measuring structure 6 comprises a guide groove 601, a slot 602 and a guide shaft 603. The guide groove 601 is opened inside the outer caliper 2, and the slot 602 is opened on both sides of the second support frame 3. The guide shaft 603 runs through the slot 602. The slot 602 is symmetrically distributed about the vertical center line of the second support frame 3, and the slot 602 and the guide shaft 603 form a rotating structure.

[0032] The working principle of a device for measuring the size of an intermediate billet of hot-rolled steel strip based on Example 1 is that when the measuring device is used, two calipers are assembled to form a set of simple practical device for measuring the intermediate billet, and the size of the intermediate billet is measured in combination with a vernier caliper. One of them is an outer caliper 2, which is suitable for measuring the size of thicker rolled pieces. For the hot-rolled intermediate billet, after the caliper is clamped, it cannot be pulled out to measure the size. Therefore, it is necessary to transfer the measuring position and combine an inner caliper 5 with the outer caliper 2 to make the measured opening consistent and reflect the same data size value. Therefore, the size value of the piece measured by the outer caliper 2 can be reflected by measuring the opening of the inner caliper 5, and the vernier caliper is used to measure the opening of the inner caliper 5. The value is the size of the rolled piece, and in this process, in order to enable the outer caliper 2 and the inner caliper 5 to be unfolded at the same time and with the same opening and closing angle, slots 602 are opened on both sides of the second support frame 3, and the outer caliper 2 and the inner caliper 5 are inserted into the corresponding slots 602, and under the action of the guide shaft 603, the outer caliper 2 and the inner caliper 5 are unfolded and the guide shaft 603 slides along the guide groove 601. Therefore, when the device is measured, the outer caliper 2 and the inner caliper 5 can be forced to open and close at a certain angle by pulling the second support frame 3 in the direction of the first support frame 1 or pressing the first support frame 1 in the direction of the second support frame 3, so that the unfolding angles of the outer caliper 2 and the inner caliper 5 remain consistent for easy measurement.

A second articulated frame 403 is arranged above the first articulated frame 401, and a torsion spring 404 is wrapped around the outer side of the rotating shaft 402. The first articulated frame 401 and the second articulated frame 403 are in a rotating structure through the rotating shaft 402, and the first articulated frame 401 is symmetrically distributed about the vertical center line of the first support frame 1.

[0035] In this embodiment, in order to avoid measurement errors caused by movement during the measurement process when the device is used, the first articulated frame 401 and the second articulated frame 403 are respectively hinged at the spacing position between the first support frame 1 and the second support frame 3, and a torsion spring 404 is sleeved on the outside of the rotating shaft 402 passing through them. Under the torsion of the torsion spring 404, the first articulated frame 401 and the second articulated frame 403 respectively elastically support the first support frame 1 and the second support frame 3, so that the second support frame 3 always elastically supports the outer caliper 2 and the inner caliper 5, so that the outer caliper 2 and the inner caliper 5 can maintain a stable deployment effect under the support of the support adjustment structure 7, so that they will not move during measurement and affect the measurement results.

[0038] In this embodiment, when the device is used, in order to avoid complicated operations that affect the use of novice users, a connecting frame 701 is sleeved on the outer sides of the first support frame 1 and the second support frame 3, and the adjusting screw 703 is rotated under the threaded connection structure of the internal threaded tube 702 and the adjusting screw 703 to push the extrusion seat 704 in the direction of the first support frame 1, and the first support frame 1 is pressed in the direction of the second support frame 3 under the push of the extrusion seat 704, so that the outer caliper 2 and the inner caliper 5 are unfolded at the same time, and the unfolding of the outer caliper 2 and the inner caliper 5 is kept stable, and the shell pulls the connecting frame 701 to take out the device as a whole to measure the unfolding angle of the outer caliper 2 and the inner caliper 5.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
