Description

Technical Field

[0001] This invention relates to the field of rebar processing equipment, and particularly to clamping components and clamping devices for rebar thread rolling machines, as well as the rebar thread rolling machine itself. Background Technology

[0002] When using reinforcing bars, it is sometimes necessary to machine threads on the ends of the bars to connect fasteners such as nuts for easy connection. In related technologies, a reinforcing bar thread rolling machine is usually used to process the reinforcing bars. During processing, the reinforcing bars need to be fully clamped and fixed to prevent the reduction in thread accuracy caused by the reinforcing bars rotating and moving along their axial direction. Therefore, a rigid clamp is used to clamp the reinforcing bars to ensure that they are completely fixed. However, when the thread rolling force and the clamping force are greater, the part of the reinforcing bar clamped by the clamp is easily damaged, affecting the quality of the reinforcing bars. Summary of the Invention

To this end, the present invention proposes a clamping component for a rebar thread rolling machine that can prevent damage to the rebar without affecting the processing accuracy of the rebar.

[0004] The present invention proposes a clamping device having the above-mentioned clamping components for a rebar rolling machine.

[0005] This invention proposes a rebar rolling machine with a clamping device.

[0006] According to a first aspect of the present invention, a clamping member for a rebar thread rolling machine includes:

[0007] A clamping base has a clamping surface, wherein the clamping surface is provided with a plurality of mounting plates that are spaced apart sequentially along a first direction, and a mounting groove is formed between two adjacent mounting plates;

[0008] An elastic pad is connected to the clamping surface of the clamping seat. The elastic pad has a mounting surface relative to the clamping surface and a contact surface opposite to the mounting surface. The mounting surface has a plurality of mounting portions spaced apart in sequence along a first direction. Each mounting portion corresponds to a mounting groove and is installed in the corresponding mounting groove. The direction away from the clamping surface of the mounting surface is a second direction. The elastic pad has a plurality of limiting cavities spaced apart in the first direction and a plurality of support members corresponding to the limiting cavities. The support members are limited and installed in the corresponding limiting cavities along the first direction and have a stroke along the second direction.

[0009] According to the first aspect of the present invention, the clamping member for a rebar rolling machine has at least the following beneficial effects: the contact surface of the elastic pad directly contacts the outer surface of the rebar, the elastic pad forms a buffer, and the rebar is flexibly clamped, making the rebar less susceptible to damage and preventing the rebar from rotating; and the first direction is the same as the axial direction of the rebar, so that the elastic pad is reinforced by multiple mounting plates along the first direction, and the elastic pad is further reinforced by multiple support members along the first direction to prevent the elastic pad from deforming along the first direction, thereby preventing the rebar from moving along the first direction; at the same time, the support members have a stroke along the second direction, and the support members will not affect the deformation of the elastic pad along the second direction, and the elastic pad can squeeze the rebar along the second direction, so as to completely fix the rebar and ensure the rebar processing accuracy without damaging the rebar.

[0010] According to some embodiments of the present invention, the support member is elastic, and the two ends of the support member along the second direction respectively abut against the two ends of the limiting cavity along the second direction to undergo elastic deformation along the second direction.

[0011] According to some embodiments of the present invention, one end of the support member away from the mounting surface is connected to the elastic pad and is movable within the limiting cavity in the second direction.

[0012] According to some embodiments of the present invention, the mounting plate is tilted.

[0013] According to some embodiments of the present invention, the support member is inclined.

[0014] According to some embodiments of the present invention, each of the limiting cavities corresponds to each of the mounting slots, and a portion of the support member is located within the mounting slot.

[0015] According to some embodiments of the present invention, a pressure detection layer is provided between the mounting surface and the clamping surface.

[0016] According to a second aspect of the present invention, a clamping device includes: two clamping members as described in the first aspect of the present invention, one being a first clamping member and the other being a second clamping member relative to the first clamping member;

[0017] A first moving component is connected to the first clamping member and / or the second clamping member, and the first moving component is used to adjust the distance between the first clamping member and the second clamping member.

[0018] The clamping device according to the second aspect of the present invention has at least the following advantages: by using the first clamping member and the second clamping member of the first aspect embodiment, the steel bar is completely fixed while avoiding damage to the steel bar, so as to maintain the processing accuracy of the steel bar.

[0019] According to some embodiments of the present invention, a controller is further included, wherein the first clamping member and / or the second clamping member have a pressure sensing layer, and the controller is electrically connected to the pressure sensing layer and the first moving component;

[0020] The controller is configured to: adjust the clamping of the first clamping member and the second clamping member to clamp the object to be clamped through the first moving component; when the pressure detected by the pressure detection layer is a preset pressure, the controller controls the first moving component to stop.

[0021] A rebar rolling machine according to a third aspect of the present invention includes:

[0022] A workbench, having a tabletop;

[0025] A pre-tensioning device is provided on the platform, located on the side of the clamping device away from the thread rolling device, for pre-tensioning the reinforcing bar held by the clamping device in the direction away from the thread rolling device.

[0026] According to the third aspect of the present invention, the rebar thread rolling machine has at least the following beneficial effects: by using the first clamping member and the second clamping member of the first aspect embodiment, the rebar is completely fixed while avoiding damage to the rebar, so as to maintain the processing accuracy of the rebar. At the same time, the rebar is pre-pulled by the pre-tensioning device, so that the elastic pad undergoes a certain pre-deformation along the axial direction of the rebar. In this way, the pre-deformation resists the axial force applied to the rebar during the thread rolling process, preventing the rebar from moving along its axial direction, so as to maintain the processing accuracy of the rebar.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0047] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0048] Reference Figures 1 to 7 As shown, a first aspect embodiment of the present invention provides a clamping member for a rebar rolling machine, including a clamping seat 100 and an elastic pad 200. The clamping seat 100 has a clamping surface, and the clamping surface is provided with a plurality of mounting plates 110 arranged at intervals along a first direction. An mounting groove 120 is formed between two adjacent mounting plates 110. The elastic pad 200 is connected to the clamping surface of the clamping seat 100. The elastic pad 200 has a mounting surface relative to the clamping surface and a contact surface opposite to the mounting surface. The mounting surface is provided with a plurality of mounting portions 210 arranged at intervals along the first direction. Each mounting portion 210 corresponds to each mounting groove 120 and is installed in the corresponding mounting groove 120. The direction away from the clamping surface of the mounting surface is the second direction. The elastic pad 200 is provided with a plurality of limiting cavities 220 arranged at intervals along the first direction and a plurality of support members 230 corresponding to the limiting cavities 220. The support members 230 are limited and installed in the corresponding limiting cavities 220 along the first direction and have a stroke along the second direction.

[0049] When the two clamping members clamp the reinforcing bar, the first direction is the axial direction of the reinforcing bar, and the second direction is the radial direction of the reinforcing bar.

[0050] In this embodiment, the clamping seat 100 is made of a rigid material, such as high-strength steel. The clamping seat 100 is rectangular in shape, and the side of the clamping seat 100 facing the reinforcing bar is the clamping surface. The clamping seat 100 also includes a main body that connects all the mounting plates 110. The main body is integrally formed with the mounting plates 110. The end of the mounting plate 110 away from the main body is chamfered so as to make smooth contact with the mounting surface of the elastic pad 200.

[0051] The elastic pad 200 is made of rubber, and its contact surface has an arc shape that conforms to the outer circumference of the reinforcing bar to fit the outer circumference of the reinforcing bar, allowing for full contact and increasing the friction between the elastic pad 200 and the outer circumference of the reinforcing bar, thus preventing the reinforcing bar from rotating. The mounting part 210 is also plate-shaped and is embedded in the corresponding mounting groove 120, so that the mounting part 210 and the mounting plate 110 are alternately distributed along the first direction. When the elastic pad 200 is subjected to a force along the first direction, it is transmitted to the mounting plate 110 through the mounting part 210. The multiple mounting plates 110 cancel out the force in the first direction, thereby increasing the deformation of the elastic pad 200 along the first direction and making it difficult for the reinforcing bar to drive the elastic pad 200 to move along the first direction. Meanwhile, the support member 230 is limited and installed in the limiting cavity 220 along the first direction, so that the support member 230 cannot move along the first direction, so that the support member 230 forms support for the elastic pad 200 along the first direction, thereby reducing the deformation of the elastic pad 200 along the first direction, making it difficult for the steel bar to drive the elastic pad 200 to move together along the first direction. At the same time, the support member 230 can move relative to the limiting cavity 220 along the second direction, so that when the elastic pad 200 undergoes elastic deformation along the second direction, the support member 230 can move along the second direction together without affecting the deformation of the elastic pad 200.

[0052] It is understandable that by having the contact surface of the elastic pad 200 directly contact the outer surface of the reinforcing bar, the elastic pad 200 forms a buffer, achieving flexible clamping of the reinforcing bar, making it less prone to damage and preventing the reinforcing bar from rotating. Furthermore, the first direction is the same as the axial direction of the reinforcing bar, so that the elastic pad 200 is reinforced by multiple mounting plates 110 along the first direction. At the same time, the elastic pad 200 is further reinforced by multiple support members 230 along the first direction to prevent the elastic pad 200 from deforming along the first direction, thereby preventing the reinforcing bar from shifting along the first direction. Meanwhile, the support members 230 have a stroke along the second direction, so the support members 230 will not affect the deformation of the elastic pad 200 along the second direction. The elastic pad 200 can compress the reinforcing bar along the second direction, so as to completely fix the reinforcing bar and ensure the processing accuracy of the reinforcing bar without damaging it.

[0053] In some specific embodiments of the present invention, the support member 230 is elastic, and the two ends of the support member 230 along the second direction respectively abut against the two ends of the limiting cavity 220 along the second direction to undergo elastic deformation along the second direction.

[0054] It is understandable that the support member 230 has elasticity along the second direction, allowing it to deform along the second direction together with the elastic pad 200. This improves the overall buffering effect of the elastic pad 200 on the reinforcing steel.

[0055] Reference Figure 2 , Figure 5 and Figure 6 As shown, in some specific embodiments of the present invention, the end of the support member 230 away from the mounting surface is connected to the elastic pad 200 and can move in the second direction within the limiting cavity 220.

[0056] It is worth understanding that the end of the support member 230 away from the mounting surface is connected to the elastic pad 200. When the elastic pad 200 undergoes elastic deformation along the second direction, the contact surface deforms before the mounting surface. This causes the end of the support member 230 near the contact surface to deform before the end near the mounting surface. In other words, the end of the support member 230 away from the mounting surface deforms first. During deformation, the support member 230 moves directly along the second direction without obstructing the movement of the elastic pad 200. This reduces the impact of the support member 230 on the elastic pad 200, resulting in a more uniform force distribution on the elastic pad 200.

[0057] Alternatively, the middle part of the support member 230 can be connected to the elastic pad 200, so that the middle part of the support member 230 and the section of the support member 230 near the contact surface will abut against the limiting cavity 220 when the elastic pad 200 contracts. This will cause the elastic pad 200 to bear excessive pressure between the end face of the support member 230 near the contact surface and the contact surface of the elastic pad 200, thereby increasing the local stress on the reinforcing bar, increasing the friction between the reinforcing bar and the elastic pad 200, and making it more difficult for the reinforcing bar to rotate and move relative to the elastic pad 200 in the first direction.

[0058] Reference Figure 4 As shown, in some specific embodiments of the present invention, the mounting plate 110 is inclined.

[0059] It is worth understanding that the mounting plate 110 is inclined. During installation, the inclined end of the mounting plate 110 faces the side where the thread rolling device 3000 for rolling the reinforcing bar is located. A pre-tensioning device 4000 is set on the side of the clamping member away from the thread rolling device 3000. When the thread rolling device 3000 processes the reinforcing bar, it will abut against the reinforcing bar and push the reinforcing bar to move towards the side where the pre-tensioning device 4000 is located. The pre-tensioning device 4000 first stretches the reinforcing bar along the direction of the reinforcing bar's movement, so that the mounting plate 110 has a tendency to rotate from the inclined state to the vertical state. Furthermore, the elastic pad 200 has a certain elastic potential energy after pre-tensioning, so that it can cancel the axial force applied to the reinforcing bar by the thread rolling device 3000 when the thread rolling device 3000 processes the reinforcing bar, so that the reinforcing bar cannot move along its axial direction, thereby improving the stability of the reinforcing bar clamping.

[0060] Meanwhile, when the mounting plate 110 rotates from the tilted state to the vertical state, the clamping force of the mounting plate 110 on the reinforcing bar along the second direction will be greater, which is more conducive to improving the clamping effect of the reinforcing bar.

[0061] In addition, refer to Figure 3As shown, the mounting plate 110 forms a wedge-shaped structure, and the mounting part 210 is also a wedge-shaped structure, and the two are interlocked.

[0062] Reference Figure 5 and Figure 6 As shown, in some specific embodiments of the present invention, the support member 230 is inclined.

[0063] It is worth understanding that the support member 230 is inclined in the same direction as the mounting plate 110. During installation, the inclined end of the support member 230 is also facing the side where the thread rolling device 3000 for rolling the reinforcing bar is located. A pre-tensioning device 4000 is set on the side of the clamping member away from the thread rolling device 3000. When the thread rolling device 3000 processes the reinforcing bar, it will abut against the reinforcing bar and push the reinforcing bar to have a tendency to move towards the side where the pre-tensioning device 4000 is located. The pre-tensioning device 4000 first stretches the reinforcing bar along the direction of the reinforcing bar's movement, so that the support member 230 has a tendency to rotate from the inclined state to the vertical state. Furthermore, the elastic pad 200 has a certain elastic potential energy after pre-tensioning, so that when the thread rolling device 3000 processes the reinforcing bar, it can cancel out the axial force applied to the reinforcing bar by the thread rolling device 3000, so that the reinforcing bar cannot move along its axial direction, thereby improving the stability of the reinforcing bar clamping.

[0064] Meanwhile, when the support plate 230 rotates from the inclined state to the vertical state, the clamping force of the support plate 230 on the reinforcing bar along the second direction will be greater, which is more conducive to improving the clamping effect of the reinforcing bar.

[0065] Reference Figure 2 , Figure 5 and Figure 6 As shown, in some specific embodiments of the present invention, each limiting cavity 220 corresponds to each mounting groove 120, and a portion of the support member 230 is located within the mounting groove 120.

[0066] It is worth understanding that the limiting cavity 220 is set in the mounting groove 120, so that the mounting plate 110, elastic pad 200, support member 230 and elastic pad 200 are formed alternately along the first direction. The mounting plate 110 and support member 230 can also jointly resist the deformation of elastic pad 200 along the first direction.

[0067] Reference Figure 2 As shown, in some specific embodiments of the present invention, a pressure detection layer 300 is provided between the mounting surface and the clamping surface.

[0068] It is understood that when the elastic pad 200 undergoes elastic deformation, a resisting force equal to the clamping force is applied to the pressure detection layer 300, enabling real-time detection of the clamping pressure. This facilitates real-time pressure control for intelligent operation. In this embodiment, the pressure detection layer 300 is a thin-film pressure sensor.

[0069] Reference Figure 7 As shown, a second aspect embodiment of the present invention provides a clamping device 1000, comprising: two clamping members according to the first aspect embodiment of the present invention and a first moving component connected to the first clamping member 1100 and / or the second clamping member 1200, wherein one of the two clamping members is the first clamping member 1100 and the other is the second clamping member 1200 relative to the first clamping member 1100; the first moving component is used to adjust the distance between the first clamping member 1100 and the second clamping member 1200.

[0070] It is understood that the first clamping member 1100 and the second clamping member 1200 are arranged opposite to each other, and the relative movement of the first clamping member 1100 and the second clamping member 1200 is realized by the first moving component, thereby achieving the clamping of the rebar located between the first clamping member 1100 and the second clamping member 1200. Furthermore, by employing the first clamping member 1100 and the second clamping member 1200 of the first aspect embodiment, the rebar is completely fixed while avoiding damage, thereby maintaining the processing accuracy of the rebar.

[0071] In this embodiment, the first moving component is drivenly connected to the first clamping member 1100 and the second clamping member 1200. Alternatively, either the first clamping member 1100 or the second clamping member 1200 can be fixed, and the first moving component is drivenly connected to the other one. Specifically, the first moving component includes a moving track, a first slider and a second slider slidably connected to the moving track, a first drive source drivenly connected to the first slider, and a second drive source drivenly connected to the second slider. The first slider is connected to the first clamping member 1100 and moves along the moving track under the drive of the first drive source. The second slider is connected to the second clamping member and moves along the moving track under the drive of the second drive source. Alternatively, the moving track can include a first track and a second track spaced apart in the same direction, with the first slider slidably connected to the first track and the second slider slidably connected to the second track.

[0072] In some specific embodiments of the present invention, a controller is also included, wherein the first clamping member 1100 and / or the second clamping member 1200 have a pressure detection layer 300, and the controller is electrically connected to the pressure detection layer 300 and the first moving component;

[0073] The controller is configured to adjust the clamping of the object to be clamped by the first moving component 1100 and the second clamping component 1200, and when the pressure detected by the pressure detection layer 300 is a preset pressure, the controller controls the first moving component to stop.

[0074] It is worth understanding that the pressure of the first clamping member 1100 and / or the second clamping member 1200 is detected by the pressure detection layer 300 to send the real-time pressure to the controller. The controller has a preset standard pressure. When the real-time pressure approaches the standard pressure, the controller controls the first moving component to stop, so that the distance between the first clamping member 1100 and the second clamping member 1200 is fixed, realizing intelligent control of the bar clamping force. Different clamping forces can be applied to different bars, and the bars are less likely to be damaged when clamped.

[0075] Reference Figure 7 As shown, a third aspect embodiment of the present invention provides a rebar thread rolling machine, comprising: a worktable 2000, a clamping device 1000, a thread rolling device 3000, and a pre-tensioning device 4000. The worktable 2000 has a table surface. The clamping device 1000 of the second aspect embodiment of the present invention is disposed on the table surface for clamping rebars. The thread rolling device 3000 is disposed on the table surface for processing the rebars clamped by the clamping device 1000. The pre-tensioning device 4000 is disposed on the table surface, located on the side of the clamping device 1000 away from the thread rolling device 3000, for pre-tensioning the rebars clamped by the clamping device 1000 in a direction away from the thread rolling device 3000.

[0076] Specifically, the clamping device 1000 is used to clamp and fix the reinforcing bar. After clamping and fixing, the pre-tensioning device 4000 pre-stretches the reinforcing bar in a direction away from the thread rolling device 3000, so that the elastic pad 200 of the clamping device 1000 has a certain pre-deformation along the axial direction of the clamping device 1000. When the thread rolling device 3000 pushes the reinforcing bar along the axial direction of the reinforcing bar, the thread rolling device 3000 will find it difficult to push the elastic pad 200 to deform along the axial direction of the reinforcing bar through the reinforcing bar, so that the clamping device 1000 has a better fixing effect on the reinforcing bar.

[0077] In this embodiment, the pre-tensioning device 4000 includes a clamping device 1000 according to the second aspect of the present invention and a second moving component arranged along a first direction. The second moving component drives the pre-tensioning device 4000 to move along the first direction, that is, to move along the axial direction of the reinforcing bar. The inclination direction of the mounting plate 110 and the clamping member of the clamping device 1000 in the pre-tensioning device 4000 is opposite to the inclination direction of the mounting plate 110 and the clamping member of the original clamping device 1000.

[0078] It is worth understanding that the first clamping member 1100 and the second clamping member 1200 of the first aspect embodiment can completely fix the steel bar while avoiding damage to the steel bar, so as to maintain the processing accuracy of the steel bar. At the same time, the steel bar is pre-pulled by the pre-tensioning device 4000, so that the elastic pad 200 undergoes a certain pre-deformation along the axial direction of the steel bar. In this way, the pre-deformation resists the axial force applied to the steel bar by the thread rolling device 3000 during processing, and prevents the steel bar from moving along its axial direction, so as to maintain the processing accuracy of the steel bar.

[0079] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
