Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically, to a wire embossing device for making structural scale models. Background Technology

[0002] In today's engineering fields such as civil engineering, architecture, and water conservancy, the study of structural performance, verification of design theories, and identification of potential problems are essential technical means. Physical scale model testing is an indispensable technique. By scaling down a prototype structure to a specific geometric scale and designing and fabricating it based on similarity theory, it simulates the entire process of structural stress and failure under actual loads in the laboratory, thus providing crucial evidence for verifying design theories, revealing failure mechanisms, and optimizing structural design schemes.

[0003] However, one of the core challenges in existing scaled-down reinforced concrete models lies in how to accurately simulate the mechanical behavior and function of the reinforcing bars in the prototype structure. The traditional and widely used technical solution is to use iron wire to replace the prototype reinforcing bars. However, the surface of iron wire is smooth and cannot form an effective mechanical interlock with the concrete like ribbed steel bars. Moreover, the slippage mechanism is completely different, resulting in unreliable test data. Summary of the Invention

[0004] The purpose of this invention is to provide a wire embossing device for making structural scale models, which solves the problem that in reinforced concrete scale models, the wire surface is smooth and does not have the rib-like texture similar to the surface of ribbed steel bars, making it impossible to form an effective mechanical interlock with the concrete, resulting in inconsistencies between the test model and the engineering prototype, and unreliable test results.

[0005] This invention is achieved through the following technical solution:

[0012] Preferably, the driven pressure shaft is connected to the middle of the lifting frame, and the top of the adjusting screw protrudes from the top of the connecting frame.

[0013] Preferably, the anti-deviation block further includes a rotating rack, a timing belt, a timing rod, a movable groove, and a lifting rod. The rotating rack is connected to the top of the anti-deviation block near one end, the timing belt is connected to the middle of the rotating rack, the timing rod is connected to one end of the timing belt, the movable groove is provided on both sides of the middle of the anti-deviation block, the lifting rod is connected to the bottom of the anti-deviation block, and the bottom of the rotating rack and the timing rod are rotatably connected to the bottom of the middle of the movable groove.

Detailed Implementation

[0025] The following is combined with Figures 1 to 6 The present invention will be described in detail below.

[0026] A wire embossing device for making a structural scale model includes a base 1, a connecting frame 3 on the top of the base 1, connecting plates 2 on both sides of the connecting frame 3 attached to the top of the base 1, a fixing block 201 on one side of the connecting plate 2, a lifting block 202 connected above the fixing block 201, a guide wheel 203 connected to one side of the fixing block 201 and the lifting block 202, a driven pressure shaft 303 connected to the middle of the connecting frame 3 near the top, an active pressure shaft 304 connected below the driven pressure shaft 303, a drive motor 5 connected to one side of the active pressure shaft 304, and an anti-deviation block 4 on one side of the connecting plate 2.

[0027] Furthermore, the lifting block 202 also includes a lifting screw 2021, which is disposed through the middle of the lifting block 202, and its bottom is rotatably connected to the top of the fixed block 201. A guide wheel 203 on one side of the fixed block 201 is parallel to the top of the active pressure shaft 304. The fixed block 201 also includes a through rod 2011, which is disposed at both ends of the top of the fixed block 201. The top of the through rod 2011 passes through the lifting block 202 and connects to the driven pressure shaft 303 and the active pressure shaft 304. The connecting frame 3 has a circular groove in the middle, and raised embossed components are provided in the circular groove in the middle of the driven pressure shaft 303 and the driving pressure shaft 304. The connecting frame 3 also includes an adjusting screw 301, a lifting groove 302 and a lifting frame 3021. The lifting groove 302 is provided on both sides of the middle of the connecting frame 3 near the top. The lifting frame 3021 is provided in the lifting groove 302. The adjusting screw 301 is connected to the top of the lifting frame 3021. The driven pressure shaft 303 is connected to the middle of the lifting frame 3021. The top of the adjusting screw 301 protrudes from the top of the connecting frame 3.

[0028] First, the wire to be embossed is passed between the guide roller 203 on one side of the fixed block 201 and the lifting block 202. The guide roller 203 straightens the wire, making it straight. The driven pressure shaft 303 and the active pressure shaft 304 are then connected, and the embossing protrusions on the side walls of the driven pressure shaft 303 and the active pressure shaft 304 apply pressure to the surface of the wire, causing the surface of the wire to deform under pressure and form rib-like patterns similar to ribbed steel bars. The active pressure shaft 304 is connected to the drive motor 5 on one side to rotate, which further embosses the wire. At the same time, the lifting block 202 can be raised and lowered by the lifting screw 2021 to accommodate wires of different diameters. The driven pressure shaft 303 can also be adjusted in distance from the active pressure shaft 304 by raising and lowering the connecting frame 3 to match the diameter of the wire.

[0029] Furthermore, the anti-deviation block 4 also includes a rotating rack 401, a timing belt 4011, a timing rod 4012, a movable groove 402, and a lifting rod 403. The rotating rack 401 is connected to the top of the anti-deviation block 4 near one end. The timing belt 4011 is connected to the middle of the rotating rack 401. The timing rod 4012 is connected to one end of the timing belt 4011. The movable groove 402 is located on both sides of the middle of the anti-deviation block 4. The lifting rod 403 is connected to the bottom of the anti-deviation block 4. The bottom of the rotating rack 401 and the timing rod 4012 are rotatably connected to the bottom of the middle of the movable groove 402. The movable groove 402 also includes a limiting block 4021 and a rack 4022. The limiting block 4021 is connected to the middle of the movable groove 402. The rack 4022... 022 is set on one side of the limiting block 4021. The rack 4022 and the rotating rack 401 mesh with the side wall gear of the synchronizing rod 4012. The lifting rod 403 also includes a connecting rod 4031, a sliding rod 4032 and a sliding groove 4033. The connecting rod 4031 is connected to the middle of the lifting rod 403. The sliding rod 4032 is connected to the connecting rod 4031 near both ends. The sliding groove 4033 is set on the top of the connecting rod 4031. One end of the sliding rod 4032 is limited to sliding connection by cooperating with the sliding groove 4033. The middle part of the connecting rod 4031 is matched with the annular groove on the lifting rod 403. The end of the sliding rod 4032 away from the connecting rod 4031 is connected to the limiting block 4021.

[0030] When the wire passes through the guide wheel 203, it first passes through the anti-deviation block 4. Then, the limiting block 4021 connected to the movable groove 402 on both sides of the middle of the anti-deviation block 4 will abut against the two sides of the wire. By abutting against the two sides of the wire, the wire will not move left or right, preventing the wire diameter from being too small and the two sides from not abutting against the limiting block, thus preventing displacement during transmission.

[0031] Simultaneously, by manually controlling the rotation of the rotating rack 401, the synchronous belt 4011 drives the synchronous rod 4012 to rotate synchronously. This causes the gear on the side wall to mesh with the rack 4022 on one side of the limiting block 4021, thereby synchronously causing the two limiting blocks 4021 to close and retract. This accommodates wires of different diameters without changing the center point, ensuring that when limiting the left and right sides of wires of different diameters, the wires remain centered between the guide wheel 203 and the active pressure shaft 304.

[0032] Then, the limiting block 4021 is connected to the movable groove 402 via the sliding rod 4032. When the limiting block 4021 is displaced, the sliding rod 4032 will move in the sliding groove 4033 at the top of the connecting rod 4031, so that the sliding rod 4032 will not interfere with the movement of the limiting block 4021. At the same time, by controlling the rotation of the lifting rod 403, it retracts into the threaded groove at the bottom of the anti-deviation block 4. The connecting rod 4031 is connected to the annular groove on the side wall of the lifting rod 403 via the central annular ring. At the same time, due to the sliding connection with the sliding rod 4032, the connecting rod 4031 will be limited by the sliding rod 4032. It will not rotate with the rotation of the lifting rod 403, but will only rise and fall with the rise and fall of the lifting rod 403, thereby driving the limiting block 4021 to rise and fall, so as to match the different heights of the center points on both sides of the wires of different diameters.

[0033] The following is a detailed implementation process of the present invention. First, the wire to be embossed is passed between the guide wheel 203 on one side of the fixed block 201 and the lifting block 202. The guide wheel 203 straightens the wire, making it straight. The driven pressure shaft 303 and the active pressure shaft 304 are connected, and the embossing protrusions on the side walls of the driven pressure shaft 303 and the active pressure shaft 304 apply pressure to the surface of the wire, causing the surface of the wire to deform under pressure and form rib-like patterns similar to ribbed steel bars. The active pressure shaft 304 is connected to the transmission motor 5 on one side to rotate, which further embosses the wire. At the same time, the lifting block 202 can be raised and lowered by the lifting screw 2021 to accommodate wires of different diameters. The driven pressure shaft 303 can also be adjusted in distance from the active pressure shaft 304 by raising and lowering the connecting frame 3 to match the diameter of the wire.

[0034] When the wire passes through the guide roller 203, it first passes through the anti-deviation block 4. Then, the limiting blocks 4021 connected to the movable grooves 402 on both sides of the anti-deviation block 4 abut against the two sides of the wire. By abutting against the two sides of the wire, the wire is prevented from shifting left or right. This prevents the wire from shifting during transmission if the diameter is too small and there is no abutment on both sides. At the same time, the rotating rack 401 is manually controlled to rotate, which drives the synchronous rod 4012 to rotate synchronously through the synchronous belt 4011. This causes the gear on the side wall to mesh with the rack 4022 on one side of the limiting block 4021, so that the two limiting blocks 4021 close and contract synchronously. This accommodates wires of different diameters without changing the center point. It ensures that when limiting the left and right sides of wires of different diameters, the wire can always stay between the guide roller 203 and the active pressure shaft 304. The center, and then the limiting block 4021 is connected to the movable groove 402 by the sliding rod 4032. When the limiting block 4021 is displaced, the sliding rod 4032 will be displaced in the sliding groove 4033 at the top of the connecting rod 4031, so that the sliding rod 4032 will not interfere with the movement of the limiting block 4021. At the same time, by controlling the rotation of the lifting rod 403, it is retracted into the threaded groove at the bottom of the anti-deviation block 4. The connecting rod 4031 is connected to the annular groove on the side wall of the lifting rod 403 by the central annular ring. At the same time, because of the sliding connection with the sliding rod 4032, the connecting rod 4031 will be limited by the sliding rod 4032. It will not rotate with the rotation of the lifting rod 403, but will only rise and fall with the rise and fall of the lifting rod 403, thereby driving the limiting block 4021 to rise and fall, so as to match the different heights of the center points on both sides of the wires of different diameters.
