Description

Technical Field

[0001] This utility model relates to the field of precision-rolled threaded ribbed anchor bars, and in particular to a cutting device for the production of precision-rolled threaded ribbed anchor bars. Background Technology

[0002] As a material used for coal mine support, precision-rolled threaded ribbed anchor bars have continuous rolled threads along their entire length and are characterized by equal strength throughout. Their production process is mature. Precision-rolled threaded ribbed anchor bars are a type of high-strength prestressed steel and are widely used in engineering fields such as bridges, slope protection, and anti-buoyancy anchors.

[0003] Existing cutting devices for producing precision-rolled threaded ribbed anchor bars involve the rolling mill body finishing the precision-rolled threaded ribbed anchor bars and then removing them from the mill body. However, coal mine support requires precision-rolled threaded ribbed anchor bars of varying lengths. Since the finished lengths of these bars are not cut into different lengths, they are not suitable for use in coal mine support. Furthermore, when cutting the precision-rolled threaded ribbed anchor bars, the ends at the cut point are prone to shaking and warping. Failure to press and tighten the ends before cutting can easily lead to deformation and unevenness of the cut surface. Moreover, when multiple precision-rolled threaded ribbed anchor bars are cut simultaneously, the cut lengths of the rust-removable sections may vary, as the length of the cut bars is not properly measured.

[0004] Therefore, a cutting device for the production of precision-rolled threaded ribbed anchor bars is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when cutting fine-rolled threaded ribbed anchor bars, the two ends of the cut point of the fine-rolled threaded ribbed anchor bars are prone to shaking and lifting. The failure to press and tighten the two ends of the cut point before cutting easily leads to deformation and unevenness of the cut surface of the fine-rolled threaded ribbed anchor bars. Therefore, this invention proposes a cutting device for the production of fine-rolled threaded ribbed anchor bars.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a cutting device for producing precision-rolled threaded ribbed anchor bars, including a base and a rolling mill body fixed at its top, and a controller fixed at the bottom of one side of the rolling mill body.

A cutting platform is set outside the limit transmission mechanism. A cutting groove is opened in the middle of the surface of the cutting platform. An anti-tilting cutting mechanism is set at the top of the cutting platform. A cutting length detection mechanism is set outside the cutting platform. The limiting and guiding mechanism includes a guiding roller rotatably mounted on the outside of the discharge hole, and limiting rings fixed to the surface of the guiding roller and located on both sides of the discharge hole; The anti-tilting cutting mechanism includes a lifting plate installed directly above the cutting platform, hydraulic telescopic rods connected to the bottom ends of both ends of the lifting plate, a cutting blade fixed to the bottom end of the lifting plate for cutting the reinforcing bars, a jacking rod sliding through both sides of the lifting plate, a spring sleeved on the surface of the jacking rod, and a tightening plate fixed to the bottom ends of several jacking rods for pressing the reinforcing bars to prevent them from tilting.

[0007] Furthermore, the discharge holes are horizontally and equidistantly distributed, the guide roller is horizontally positioned with its top end located at the bottom of the discharge hole, and side plates fixed to both sides of the base are rotatably mounted on both ends of the guide roller, while the limiting ring is vertically positioned.

[0008] Furthermore, support legs are fixed at the four corners of the bottom of the cutting platform. The support legs are vertically fixed to the top two ends of the base. Placement slots are opened at the top of the cutting platform and on both sides of the cutting groove. The placement slots have a V-shaped cross-section and are horizontally set at the outer end of the discharge hole.

[0009] Furthermore, the lifting plate is horizontally positioned, the hydraulic telescopic rod is vertically fixed on both sides of the base, guide rods are fixed at the four corners of the top of the cutting platform, guide holes for the guide rods to slide through are opened at the four corners of the lifting plate, and a fixing frame is fixed at the top of the four guide rods. The fixing frame has a cross-shaped structure and is horizontally positioned above the lifting plate.

[0010] Furthermore, the lifting plate has insertion holes on both sides of its surface, the jacking rod slides through the insertion holes, the spring is located between the tensioning plate and the lifting plate, and a nut is connected to the top of the jacking rod at the top of the insertion hole.

[0011] Furthermore, the top clamping plate has a rectangular plate structure with a through groove in the middle. The through groove is a rectangular groove structure and is located directly below the cutting blade and directly above the cutting groove. At the bottom end of the top clamping plate and on both sides of the through groove, pressure strips are evenly fixed. The pressure strips have a V-shaped cross-section and are located directly above the placement groove.

[0012] Furthermore, the cutting length detection mechanism has mounting slots on both sides of the cutting platform, a length detection frame for detecting the length of the cut rebar is inserted into both ends of the mounting slot, and a contact sensor is fixedly installed on the inner side of the outer end of the length detection frame.

[0013] Furthermore, the mounting groove is a T-shaped structure, the length detection frame is a U-shaped structure and is horizontally set, with both ends being T-shaped structures and slidingly snapped into the mounting groove. The length dimensions are uniformly engraved on the inner sides of both ends of the length detection frame, and connecting holes are opened on the outer sides of both ends of the length detection frame. The connecting holes are threaded holes.

[0014] Furthermore, the internal thread of the connecting hole rotates through a tightening bolt, the inner end of which is fastened against the inner side of the mounting groove. The contact sensors are located at the outer end of the discharge hole and are aligned one by one, and are electrically connected to the controller.

[0015] Furthermore, a feeding platform is connected to the outside of the cutting platform. The feeding platform is inclined and its bottom end is fixedly attached to one end of the base. The surface of the feeding platform is evenly provided with sliding grooves, which are aligned with the outer end of the discharge hole.

[0016] Compared with the prior art, the cutting device for producing precision-rolled threaded ribbed anchor bars proposed in this utility model has the following advantages: 1. In this utility model, after the precision-rolled threaded ribbed anchor bar is removed from the discharge hole on the side of the rolling mill body, it is guided and limited by the transmission roller and the limiting ring to ensure that the precision-rolled threaded ribbed anchor bar moves stably and accurately to the cutting table. At the same time, the hydraulic telescopic rod drives the lifting plate to descend, so that the top plate first presses down against the surface of the precision-rolled threaded ribbed anchor bar, so that the precision-rolled threaded ribbed anchor bar is stably placed in the pressing strip and the placement groove. As the lifting plate continues to move downward, the cutting blade cuts the precision-rolled threaded ribbed anchor bar in the middle of the cutting groove, keeping both ends of the precision-rolled threaded ribbed anchor bar stable and not tilting or shaking, thus improving the quality of the cut surface of the precision-rolled threaded ribbed anchor bar.

[0017] 2. In this invention, a length detection frame is installed at the outer end of the cutting table via an installation groove and a tightening bolt. Contact sensors are evenly installed on the inner side of the outer end of the length detection frame. Therefore, according to the length of the fine-rolled threaded ribbed anchor bar that needs to be cut, the position of the length detection frame is moved and adjusted along the installation groove to the required cutting length. After the fine-rolled threaded ribbed anchor bar is moved out of the discharge hole of the mill body, it continues to move along the cutting table until the outer end of the fine-rolled threaded ribbed anchor bar abuts the outer end of the length detection frame and contacts the contact sensor. This allows detection that multiple fine-rolled threaded ribbed anchor bars have all moved out of the required cutting length, which helps to maintain the accuracy of the uniformly cut fine-rolled threaded ribbed anchor bar length and avoids inconsistent lengths.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] For examples, please refer to Figures 1 to 5 The diagram shows a cutting device for producing precision-rolled threaded ribbed anchor bars, including a base 1 and a rolling mill body 2 fixed at its top, a controller 3 fixed at the bottom of one side of the rolling mill body 2, a discharge hole 4 on the side of the rolling mill body 2 for removing precision-rolled bars, a limit transmission mechanism at the top of the base 1 and outside the discharge hole 4, a cutting platform 8 outside the limit transmission mechanism, a cutting groove 24 in the middle of the surface of the cutting platform 8, an anti-tilting cutting mechanism at the top of the cutting platform 8, and a cutting length detection mechanism outside the cutting platform 8.

[0022] The limiting and guiding mechanism includes a guiding roller 30 rotatably mounted on the outside of the discharge hole 4, and limiting rings 6 fixed on the surface of the guiding roller 30 and located on both sides of the discharge hole 4.

[0023] The discharge holes 4 are horizontally and equidistantly distributed. The guide roller 30 is horizontally set with its top end located at the bottom of the discharge hole 4. The two ends of the guide roller 30 are rotatably mounted with side plates 5 fixed to both sides of the base 1. The limiting ring 6 is vertically set.

[0024] After the fine-rolled threaded rib anchor bar is removed from the discharge hole 4 on the side of the mill body 2, it is guided and limited by the transmission roller 30 and the limiting ring 6 to keep the fine-rolled threaded rib anchor bar moving stably and accurately onto the cutting table 8.

[0025] The anti-tilting cutting mechanism includes a lifting plate 19 installed directly above the cutting platform 8, hydraulic telescopic rods 7 connected to the bottom ends of both ends of the lifting plate 19, a cutting blade 31 fixed to the bottom end of the lifting plate 19 for cutting the reinforcing bars, a jacking rod 21 sliding through both sides of the lifting plate 19, a spring 17 sleeved on the surface of the jacking rod 21, and a clamping plate 16 fixed to the bottom end of several jacking rods 21 for pressing the reinforcing bars to prevent them from tilting.

[0026] Support legs 10 are fixed at the four corners of the bottom of the cutting platform 8. The support legs 10 are vertically fixed to the top two ends of the base 1. Placement slots 15 are opened at the top of the cutting platform 8 and on both sides of the cutting groove 24. The placement slots 15 have a V-shaped cross section and are horizontally set at the outer end of the discharge hole 4.

[0027] The lifting plate 19 is set horizontally, the hydraulic telescopic rod 7 is vertically fixed on both sides of the base 1, the top of the cutting platform 8 is fixed with guide rods 18 at the four corners, the lifting plate 19 has guide holes 25 at the four corners for the guide rods 18 to slide through, and the top of the four guide rods 18 is fixed with a fixing frame 22. The fixing frame 22 has a cross-shaped structure and is set horizontally above the lifting plate 19.

[0028] The lifting plate 19 has insertion holes 26 on both sides of its surface. The actuating rod 21 slides through the insertion holes 26. The spring 17 is located between the tightening plate 16 and the lifting plate 19. The top of the actuating rod 21, located at the top of the insertion hole 26, is connected to a nut 20.

[0029] The top clamping plate 16 is a rectangular plate structure with a through groove 28 in the middle. The through groove 28 is a rectangular groove structure and is located directly below the cutting blade 31 and directly above the cutting groove 24. The bottom end of the top clamping plate 16 and the positions on both sides of the through groove 28 are evenly fixed with pressure strips 27. The pressure strips 27 have a V-shaped cross section and are located directly above the placement groove 15.

[0030] The hydraulic telescopic rod 7 drives the lifting plate 19 to descend, causing the top plate 16 to first press against the surface of the fine-rolled threaded rib anchor bar, so that the fine-rolled threaded rib anchor bar is stably placed in the pressure bar 27 and the placement groove 15. As the lifting plate 19 continues to move downward, the cutting blade 31 cuts the fine-rolled threaded rib anchor bar in the middle of the cutting groove 24, keeping both ends of the fine-rolled threaded rib anchor bar stable and not tilting or shaking, thus improving the quality of the cut surface of the fine-rolled threaded rib anchor bar.

[0031] The cutting length detection mechanism has mounting slots 23 on both sides of the cutting table 8, a length detection frame 11 for detecting the length of the cut rebar is inserted into both ends of the mounting slots 23, and a contact sensor 14 is fixedly installed on the inner side of the outer end of the length detection frame 11.

[0032] The mounting slot 23 has a T-shaped structure, and the length detection frame 11 has a U-shaped structure and is set horizontally. Both ends of the frame 11 have T-shaped structures and are slidably snapped into the mounting slot 23. The length dimensions are evenly engraved on the inner sides of both ends of the length detection frame 11, and the outer sides of both ends of the length detection frame 11 have connecting holes 29, which are threaded holes.

[0033] The internal thread of the connecting hole 29 rotates through the tightening bolt 9, and the inner end of the tightening bolt 9 is fastened to the inner side of the mounting groove 23. The contact sensor 14 is located at the outer end of the discharge hole 4 and is aligned with it, and is electrically connected to the controller 3.

[0034] After the fine-rolled threaded ribbed anchor bars are removed from the discharge hole 4 on the side of the mill body 2, they continue to move along the cutting table 8 until the outer end of the fine-rolled threaded ribbed anchor bars abuts the outer end of the length detection frame 11 and contacts the contact sensor 14. The contact sensor 14 transmits information to the controller 3, indicating that the length of the multiple fine-rolled threaded ribbed anchor bars with cuts has reached the required size. The lifting plate 19 is lowered by the hydraulic telescopic rod 7, and the fine-rolled threaded ribbed anchor bars are cut by the cutting blade 31. This allows the detection that multiple fine-rolled threaded ribbed anchor bars have all moved out of the required cut length, which helps to maintain the accuracy of the cut length of the fine-rolled threaded ribbed anchor bars and avoids the situation of inconsistent lengths.

[0035] The cutting platform 8 is connected to the outer side of the unloading platform 12. The unloading platform 12 is set at an angle, and its bottom end is fixedly connected to one end of the base 1. The surface of the unloading platform 12 is evenly provided with sliding grooves 13, which are aligned with the outer end of the discharge hole 4.

[0036] Working method: After the fine-rolled threaded rib anchor bar is moved out of the discharge hole 4 on the side of the mill body 2, it is guided and limited by the transmission roller 30 and the limiting ring 6 to keep the fine-rolled threaded rib anchor bar moving stably and accurately onto the cutting table 8. At the same time, the hydraulic telescopic rod 7 drives the lifting plate 19 to descend, so that the top plate 16 first presses down against the surface of the fine-rolled threaded rib anchor bar, so that the fine-rolled threaded rib anchor bar is stably placed in the pressing strip 27 and the placement groove 15. As the lifting plate 19 continues to move downward, the cutting blade 31 cuts the fine-rolled threaded rib anchor bar in the middle of the cutting groove 24, keeping the two ends of the fine-rolled threaded rib anchor bar stable and not tilting or shaking, thus improving the quality of the cut surface of the fine-rolled threaded rib anchor bar.

[0037] A length detection frame 11 is installed at the outer end of the cutting table 8 via the mounting groove 23 and the tightening bolt 9. Contact sensors 14 are evenly installed on the inner side of the outer end of the length detection frame 11. Therefore, according to the length that the fine-rolled threaded rib anchor bar needs to be cut off, the position of the length detection frame 11 is moved and adjusted along the mounting groove 23 to the length that needs to be cut off. After the fine-rolled threaded rib anchor bar is moved out from the discharge hole 4 on the side of the mill body 2, it continues to move along the cutting table 8 until the outer end of the fine-rolled threaded rib anchor bar abuts the outer end of the length detection frame 11 and contacts the contact sensor 14. The contact sensor 14 transmits information to the controller 3, showing that the length of multiple fine-rolled threaded rib anchor bars that have been cut off has reached the required size. The lifting plate 19 is lowered by the hydraulic telescopic rod 7, and the fine-rolled threaded rib anchor bar is cut off by the cutting blade 31. This allows it to be detected that multiple fine-rolled threaded rib anchor bars have moved out to the required length, which helps to maintain the accuracy of the cut length of the fine-rolled threaded rib anchor bars and avoids the situation of inconsistent lengths.

[0038] When the outer end of some fine-rolled threaded ribbed anchor bars fails to contact the contact sensor 14, the contact sensor 14 of the fine-rolled threaded ribbed anchor bars that fails to contact the contact sensor 14 transmits the information of non-contact to the controller 3. The controller 3 does not control the movement of the hydraulic telescopic rod 7, and manually checks the fine-rolled threaded ribbed anchor bars that fail to contact the contact sensor 14. The controller 3 also manually moves the outer end of the fine-rolled threaded ribbed anchor bars to contact the contact sensor 14 to maintain the accurate length of the uniformly cut fine-rolled threaded ribbed anchor bars.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
