Description

Technical Field

[0001] This invention relates to the field of anchor bolt processing equipment, and in particular to a novel anchor bolt processing equipment that can achieve anchor bolt chamfering and diameter reduction while improving anchor bolt processing efficiency. Background Technology

[0002] As a key load-bearing member in underground engineering and slope protection, anchor bolts typically require diameter reduction and chamfering at their ends to facilitate the installation of mounting plates and nuts and ensure smooth thread insertion. Currently, the industry generally treats diameter reduction and chamfering as two separate processes: diameter reduction is often performed using specialized diameter reduction machines or cold heading equipment, with radial compression of the bolt end achieved through a die; while chamfering relies on ordinary lathes for machining, or manual trimming of sharp edges using hand tools. Because diameter reduction and chamfering are performed on different machine tools, anchor bolts need to be frequently transferred and re-clamped between various workstations.

[0003] Furthermore, existing diameter reduction equipment lacks chamfering functionality, forcing the use of lathe cutting as a supplementary method for the chamfering process. Lathe chamfering is a material removal process, and its feed rate is much lower than that of diameter reduction forming. This severe mismatch in production capacity often results in the diameter reduction station waiting for the chamfering station, leading to a decrease in the overall line utilization rate.

[0040] The feeding assembly is connected to the feeding device.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a power device, which is mounted on the frame and transmits power; a diameter reduction device is provided on one side of the power device, allowing the diameter reduction device to slide along a fixed direction on the frame using the power transmitted by the power device; a clamping device is provided on one side of the diameter reduction device, allowing the clamping device to fix the anchor rod, thereby cooperating with the diameter reduction device to simultaneously complete the diameter reduction and chamfering actions; the clamping device is slidably connected to the frame, allowing the clamping device to be adjusted in position to accommodate anchor rods of different lengths; a feeding device is provided on one side of the clamping device, allowing the feeding device to transmit the anchor rod to the clamping device for anchor rod transmission; and a feeding device is provided on one side of the feeding device, allowing the feeding device to transmit the anchor rod step by step from a lower position to the feeding port of the feeding device, thereby achieving a complete feeding action.

[0042] This invention relates to a diameter reduction device comprising a diameter reduction base, with a diameter reduction pipe on one side of the base. A diameter reduction assembly is provided on the diameter reduction pipe, allowing for disassembly and installation on the pipe via a through-hole in the base. The assembly includes a diameter reduction section with a chamfered portion on one side, allowing the anchor rod to be fixed to a clamping device. One end of the anchor rod is inserted into the diameter reduction pipe, undergoing diameter reduction via the reduction section and chamfering via the chamfered portion, thus completing both diameter reduction and chamfering processes in a single operation. The detachable connection between the diameter reduction assembly and the pipe allows for the processing of anchor rods with different requirements simply by replacing the diameter reduction assembly when performing diameter reduction or chamfering operations of different sizes.

[0043] This invention utilizes a clamping device comprising a first clamping assembly and a second clamping assembly, both slidably connected to a frame. This allows the first and second clamping assemblies to be adjusted in position on the frame to accommodate anchor bolts of different lengths. Both the first and second clamping assemblies are equipped with detachably connected clamping modules, enabling the replacement of clamping modules with appropriate dimensions when processing anchor bolts of different sizes. The clamping modules feature clamping portions with clamping threads, which lock the anchor bolt in place, ensuring its secure fixation within the clamping device. This, in conjunction with a diameter reduction device, completes the diameter reduction and chamfering processes, providing a high-quality raw material foundation and process guarantee for subsequent thread rolling, heat treatment, surface treatment, and automated production line integration.

[0044] This invention features a first hydraulic assembly in the first fixed clamping component, which includes a first supporting telescopic rod. A second hydraulic assembly in the second fixed clamping component includes a second supporting telescopic rod. Both the first and second supporting telescopic rods are positioned on the surface of the clamping portion. When an anchor rod is transmitted down through the feeding device, it first contacts the clamping portions of the first and second movable clamping components. Then, the first and second supporting telescopic rods extend to hold the anchor rod in place. As the first and second movable clamping components move closer to the center, the first and second supporting telescopic rods retract simultaneously until both the first and second clamping components clamp the anchor rod tightly. Finally, a diameter reduction and chamfering action are performed. The feeding device includes a sliding feeding plate, which is slidably connected to the frame via a sliding component. This allows the sliding feeding plate to slide on the frame, enabling the feeding of anchor rods of different lengths.

[0045] This invention, through its high-quality, integrated chamfering, not only eliminates the time required for chamfering as a separate process, but also significantly reduces the failure rate and rework rate of subsequent stages in multiple dimensions, such as thread rolling introduction, nut assembly, heat treatment crack prevention, surface coating quality, and the smoothness of automated flow, thereby improving the operating efficiency and product qualification rate of the entire processing line.

[0051] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides a novel anchor bolt processing equipment that can achieve anchor bolt chamfering and diameter reduction while improving anchor bolt processing efficiency.

[0052] Example 1

[0053] like Figure 1-4As shown, this invention provides a novel anchor bolt processing equipment that can achieve anchor bolt chamfering and diameter reduction while improving anchor bolt processing efficiency, comprising a frame 1. The frame 1, serving as the load-bearing foundation of the entire equipment, is welded from high-strength steel, possessing sufficient rigidity and stability to withstand the impact and vibration forces generated during processing. A power unit 2, preferably a hydraulic power station or servo motor drive system, is installed on the upper part of the frame 1 to provide the driving force required for processing. A diameter reduction device 5 is connected to one side of the power unit 2, and this device 5 is slidably connected to the frame 1 via a sliding component 11. This allows the diameter reduction device 5 to reciprocate along the length of the frame 1 under the drive of the power unit 2, thereby moving closer to or away from the clamping device 4 to complete the diameter reduction and chamfering processing of the anchor bolt end. A clamping device 4 is also slidably connected to the frame 1 via the sliding component 11, used to adjust its position on the frame 1 according to the length of the anchor bolt, achieving reliable clamping of anchor bolts of different lengths. A feeding device 6 is provided on one side of the clamping device 4. The feeding device 6 is fixedly or slidably connected to the frame 1 and is used to orderly transport the anchor rods to be processed into the clamping device 4. A loading device 8 is also provided on one side of the feeding device 6. The loading device 8 is used to gradually lift the anchor rods from a low position and transfer them to the inlet position of the feeding device 6, thereby realizing a complete automatic loading action.

[0054] In this embodiment, the frame 1 is also provided with a sliding component 11. This sliding component 11 is preferably a linear guide pair or a sliding groove and slider cooperation structure to ensure the smoothness and positioning accuracy of each sliding component when moving on the frame 1. A material receiving device 7 is provided at the bottom of the frame 1 for collecting the finished anchor rods after processing. The material receiving device 7 includes a material receiving port 71, and a material receiving component 72 is provided at the bottom of the material receiving port 71. The material receiving component 72 is preferably an inclined slide or a collection box. A material passage trough 13 is provided on the frame 1. The material receiving port 71 is connected to the frame 1, and the positions of the material receiving port 71 and the material passage trough 13 are vertically aligned, so that after the finished anchor rods are released from the clamping device 4, they sequentially pass through the material passage trough 13 and the material receiving port 71 into the material receiving component 72, completing automatic material collection.

[0055] The diameter reduction device 5 in this embodiment specifically includes a diameter reduction base 51, which is fixedly connected to the output end of the power device 2 to receive the driving force transmitted by the power device 2. A diameter reduction pipe 52 is fixedly provided on one side of the diameter reduction base 51. The diameter reduction pipe 52 is a hollow cylindrical structure, and its inner cavity is used to accommodate the diameter reduction component 53. The diameter reduction component 53 is provided inside the diameter reduction pipe 52. The diameter reduction component 53 is detachably connected to the inner wall of the diameter reduction pipe 52 by means of threaded connection or flange connection. The diameter reduction component 53 includes a diameter reduction part 54, which is a conical inner hole structure. Its inner diameter gradually decreases along the anchor rod entry direction, and is used to radially compress and shape the end of the anchor rod. An integrally formed chamfer part 55 is also provided on one side of the diameter reduction part 54. The chamfer part 55 is located at the end of the diameter reduction part 54, and the inner wall of the chamfer part 55 is provided with a conical surface or arc surface at a preset angle, so as to chamfer the edge of the end of the anchor rod immediately after the diameter reduction of the anchor rod is completed. The integrated design of the diameter reduction section 54 and the chamfering section 55 allows the anchor bolt to complete both diameter reduction and chamfering processes continuously in a single feed, eliminating the need to change equipment or re-clamp, thus greatly improving processing efficiency. Furthermore, since the diameter reduction component 53 and the diameter reduction pipe 52 are detachably connected, when processing anchor bolts of different specifications, only the diameter reduction component 53 with the corresponding diameter reduction size and chamfering angle needs to be replaced, without needing to replace the entire machine, significantly improving the equipment's versatility and applicability.

[0056] The clamping device 4 in this embodiment includes a first clamping component 41 and a second clamping component 42. The first clamping component 41 and the second clamping component 42 are arranged at intervals along the length direction of the anchor rod. They work together to provide double-point support and clamping for the anchor rod, effectively preventing the anchor rod from bending or shifting during the diameter reduction process. The bottom of the first clamping component 41 and the second clamping component 42 are respectively provided with a second sliding groove 43, and the first clamping component 41 and the frame 1, as well as the second clamping component 42 and the frame 1, are slidably connected by sliding members 11. Specifically, the sliding members 11 are embedded in the second sliding grooves 43, so that the first clamping component 41 and the second clamping component 42 can slide independently along the length direction of the frame 1, thereby flexibly adjusting the distance between them according to the actual length of the anchor rod to adapt to the clamping requirements of anchor rods of different specifications.

[0057] The first clamping assembly 41 in this embodiment includes a first fixed clamping member 44, which is fixedly disposed relative to the base of the first clamping assembly 41. A first movable clamping member 45 is disposed opposite to one side of the first fixed clamping member 44, and the first movable clamping member 45 can move closer to or further away from the first fixed clamping member 44 to clamp and release the anchor rod. Similarly, the second clamping assembly 42 includes a second fixed clamping member 46, which is fixedly disposed relative to the base of the second clamping assembly 42. A second movable clamping member 47 is disposed opposite to one side of the second fixed clamping member 46, and the second movable clamping member 47 can move closer to or further away from the second fixed clamping member 46.

[0058] The first movable clamping component 45 in this embodiment includes a first sliding base 451. A first sliding clamping block 452 is provided on the upper part of the first sliding base 451, and the first sliding clamping block 452 is slidably connected to the first sliding base 451 through a slide rail or guide post. The second movable clamping component 47 includes a second sliding base 471. A second sliding clamping block 472 is provided on the upper part of the second sliding base 471, and the second sliding clamping block 472 is slidably connected to the second sliding base 471 through a slide rail or guide post. With the above structure, the first sliding clamping block 452 and the second sliding clamping block 472 can perform precise clamping and releasing actions relative to the first fixed clamping component 44 and the second fixed clamping component 46 respectively under the push of the clamping drive mechanism (such as a cylinder or hydraulic cylinder), ensuring that the anchor rod is firmly locked during the processing.

[0059] In this embodiment, both the first clamping assembly 41 and the second clamping assembly 42 are equipped with detachably connected clamping modules 48. These clamping modules 48 are detachably connected to the first fixed clamping component 44, the first sliding clamping block 452, the second fixed clamping component 46, and the second sliding clamping block 472 via bolts or quick-change clips. Each clamping module 48 has a clamping portion 49, which is an arc-shaped concave structure adapted to the outer wall of the anchor rod. The surface of the clamping portion 49 is provided with clamping threads 40, which are raised spiral patterns used to embed into the thread grooves on the surface of the anchor rod during clamping, thereby locking the axial position of the anchor rod and preventing axial movement or rotation of the anchor rod due to force during diameter reduction and chamfering processes. By replacing clamping modules 48 of different specifications, the clamping requirements of anchor rods of different diameters can be met, further improving the versatility of the equipment.

[0060] In this embodiment, the first fixed clamping component 44 is further provided with a first hydraulic assembly 401, which includes a first supporting telescopic rod 402. The movable end of the first supporting telescopic rod 402 is connected to or abuts against the surface of the clamping part 49. The second fixed clamping component 46 is provided with a second hydraulic assembly 403, which includes a second supporting telescopic rod 404. The movable end of the second supporting telescopic rod 404 is also connected to or abuts against the surface of the clamping part 49. During the feeding process, when the anchor rod is conveyed to the clamping device 4 by the feeding device 6, the anchor rod first contacts the clamping part 49 on the first moving clamping component 45 and the second moving clamping component 47. At this time, the first supporting telescopic rod 402 and the second supporting telescopic rod 404 extend outward, pre-pressing and holding the anchor rod from another direction to prevent the anchor rod from coming out of the clamping part 49. Subsequently, the first sliding base 451 and the second sliding base 471 respectively drive the first sliding clamping block 452 and the second sliding clamping block 472 to slide closer to the corresponding fixed clamping component. During this process, the first support telescopic rod 402 and the second support telescopic rod 404 retract synchronously until the clamping parts 49 of the first clamping assembly 41 and the second clamping assembly 42 completely clamp the anchor rod. This ensures that the anchor rod maintains the correct axial position during the clamping process, avoiding bending or deflection of the anchor rod due to uneven clamping force.

[0061] The feeding device 6 in this embodiment includes a sliding feeding plate 61. The bottom of the sliding feeding plate 61 is provided with a first groove 62. The sliding feeding plate 61 is slidably connected to the sliding component 11 on the frame 1 through the first groove 62, so that the sliding feeding plate 61 can slide along the length direction of the frame 1 to adapt to the feeding requirements of anchor rods of different lengths. A fixed feeding plate 62 is fixedly provided on one side of the sliding feeding plate 61, and a fixed plate 63 is fixedly provided on the other side. Both the fixed feeding plate 62 and the sliding feeding plate 61 are provided with feeding grooves through which anchor rods can pass. A rotating baffle is provided at the end of the feeding groove. When one anchor rod is being processed, the rotating baffle can restrict the position of the next anchor rod. There is also a bottom baffle at the bottom of the rotating baffle. The anchor rod first falls onto the bottom baffle and is then pushed to the processing position by the first moving clamping component 45 and the second moving clamping component 47. A connecting column 64 is fixedly connected between the fixed feed plate 62 and the fixed plate 63. The connecting column 64 is preferably a smooth guide column arranged in parallel. A guide hole is provided on the sliding feed plate 61. The sliding feed plate 61 is slidably connected to the connecting column 64 through the guide hole, so that the sliding feed plate 61 can be guided and limited by the connecting column 64 when sliding along the frame 1, ensuring the stability and straightness of the sliding feed plate 61 during movement, thereby ensuring that the anchor rod can be accurately aligned with the clamping center of the clamping device 4.

[0062] The feeding device 8 in this embodiment includes a feeding assembly 81, which is preferably a chain lifting mechanism or an inclined slide structure, used to take out the anchor rods to be processed one by one from the lower hopper and lift them to the higher position. A conveying assembly 82 is provided on one side of the feeding assembly 81, which is preferably a conveyor belt or conveyor roller, used to transport the anchor rods transferred from the feeding assembly 81 horizontally to the inlet position of the feeding device 6. The feeding assembly 81 is connected to the inlet end of the feeding device 6, ensuring that the anchor rods can smoothly transition from the conveying assembly 82 to the sliding feed plate 61 and the fixed feed plate 62, thereby realizing a complete automated process from bulk material feeding to fixed-point feeding.

[0063] Example 2

[0064] This embodiment uses a standard anchor rod with a processing length of 2.4 meters and a diameter of 22 millimeters as an example to illustrate the working process of the equipment of the present invention.

[0065] First, based on the diameter specifications of the anchor rod to be processed, the operator selects the appropriate diameter reduction assembly 53 and clamping module 48. The diameter reduction assembly 53 is screwed into the diameter reduction pipe 52 via threads, ensuring that the axes of the diameter reduction section 54 and the chamfered section 55 coincide with the axis of the diameter reduction pipe 52. Simultaneously, the clamping module 48, with a corresponding 22 mm inner diameter clamping section 49, is installed onto the first fixed clamping component 44, the first sliding clamping block 452, the second fixed clamping component 46, and the second sliding clamping block 472, respectively.

[0066] Subsequently, based on the length of the anchor rod, the positions of the first clamping assembly 41 and the second clamping assembly 42 are adjusted by sliding along the sliding component 11 on the frame 1, so that the distance between them is approximately 1.2 meters, ensuring that the end of the anchor rod can just extend into the reduced diameter pipe 52 after being clamped. At the same time, the position of the sliding feed plate 61 on the frame 1 is adjusted by sliding, so that its discharge end is aligned with the feed side of the first clamping assembly 41.

[0067] After the equipment is started, the feeding component 81 of the feeding device 8 lifts the anchor rods in the hopper one by one onto the conveying component 82. The conveying component 82 then transports the anchor rods horizontally to the sliding feed plate 61 and the fixed feed plate 62 of the feeding device 6. Guided by the feeding device 6, the anchor rods slide axially into the clamping device 4. At this time, the first support telescopic rod 402 and the second support telescopic rod 404 extend outward simultaneously, pre-pressing the anchor rods onto the clamping portions 49 of the first movable clamping component 45 and the second movable clamping component 47 from opposite directions. Next, the first sliding base 451 and the second sliding base 471 slide towards the corresponding fixed clamping components under hydraulic drive, driving the first sliding clamping block 452 and the second sliding clamping block 472 closer to the anchor rods. Simultaneously, the first support telescopic rod 402 and the second support telescopic rod 404 retract synchronously until the anchor rods are completely clamped between the first clamping component 41 and the second clamping component 42. The clamping thread 40 on the clamping part 49 is embedded in the thread groove on the surface of the anchor rod to achieve axial locking.

[0068] After clamping, the power unit 2 is activated, driving the reducing base 51 to slide the reducing pipe 52 along the frame 1 towards the clamping device 4. The end of the anchor rod first enters the reducing pipe 52 and passes through the reducing section 54 of the reducing assembly 53. Under the squeezing action of the conical inner hole of the reducing section 54, the end of the anchor rod undergoes radial compression deformation, and the outer diameter is reduced from 22 mm to 20 mm. As the reducing device 5 continues to feed, the end of the anchor rod after reducing its diameter then enters the chamfering section 55. Guided by the preset conical surface of the chamfering section 55, the sharp edge of the anchor rod end is rolled into a smooth chamfered structure, which can be formed without cutting. Thus, the anchor rod completes the two processes of reducing diameter and chamfering simultaneously in the same station and in the same feed stroke.

[0069] After processing, the power unit 2 drives the diameter reduction device 5 to slide back to its original position. The first sliding clamping block 452 and the second sliding clamping block 472 of the clamping device 4 slide back to release the anchor rod, while the first support telescopic rod 402 and the second support telescopic rod 404 retract. The processed anchor rod falls into the material passage trough 13 at the bottom of the frame 1 under the action of gravity, and enters the material receiving component 72 through the material receiving port 71 for collection. Subsequently, the next anchor rod to be processed begins to be fed, entering the next work cycle. The entire processing process realizes fully automatic continuous operation, and the processing cycle of a single anchor rod is significantly shortened.

[0070] This invention provides a novel anchor bolt processing equipment that can achieve anchor bolt chamfering and diameter reduction while improving anchor bolt processing efficiency. Its core working principle is as follows: by integrating the diameter reduction function and the chamfering function into the same diameter reduction component, and with the cooperation of a clamping device and a feeding device that can slide along the frame, the anchor bolt can continuously complete the two processes of diameter reduction and chamfering in the same station and in the same feed stroke. At the same time, with the help of the coordinated actions of automated feeding, clamping and receiving, continuous assembly line operation of anchor bolt end processing is realized.

[0071] Specifically, the operation process of this equipment is as follows:

[0072] I. Preparatory Work Phase

[0073] Before starting the equipment, the operator selects the appropriate diameter reduction assembly 53 and clamping module 48 according to the diameter and length specifications of the anchor rod to be processed. In the diameter reduction assembly 53, the final inner diameter of the tapered inner hole of the diameter reduction part 54 should be equal to the target diameter required at the end of the anchor rod after diameter reduction, and the cone angle and depth of the chamfered part 55 should match the chamfering process requirements of the anchor rod of this specification. The inner diameter of the clamping part 49 of the clamping module 48 should be consistent with the outer diameter of the anchor rod, and the tooth profile of the clamping thread 40 should be adapted to the surface of the anchor rod. After selection, the diameter reduction assembly 53 is screwed into the diameter reduction pipe 52 by thread or flange, and the clamping module 48 is installed on the first fixed clamping component 44, the first sliding clamping block 452, the second fixed clamping component 46, and the second sliding clamping block 472 respectively.

[0074] Subsequently, based on the axial length of the anchor rod, the distance between the first clamping assembly 41 and the second clamping assembly 42 is adjusted by sliding along the sliding component 11 on the frame 1, so that the two provide double-point support for the anchor rod. This ensures that after the anchor rod is clamped, the end to be processed can be precisely inserted into the reduced-diameter pipe 52 and remain coaxial with the axis of the reduced-diameter assembly 53. At the same time, the sliding feed plate 61 of the feeding device 6 is adjusted by sliding so that its discharge end is accurately aligned with the feed side of the first clamping assembly 41, ensuring that the anchor rod can smoothly transition from the feeding device 6 to the clamping device 4.

[0075] II. Material Feeding and Intake Stage

[0076] The feeding assembly 81 of the feeding device 8 extracts the anchor rods to be processed one by one from the low-level hopper and lifts them onto the conveying assembly 82. The conveying assembly 82 transports the anchor rods horizontally to the sliding feed plate 61 and the fixed feed plate 62 of the feeding device 6. Guided by the feeding device 6, the anchor rods slide axially into the clamping device 4. At this time, the anchor rods first enter the clamping part 49 of the first moving clamping member 45 and the second moving clamping member 47.

[0077] III. Pre-compression and clamping stage

[0078] Once the anchor rod reaches the clamping position, the first hydraulic assembly 401 and the second hydraulic assembly 403 are activated simultaneously. The first support telescopic rod 402 and the second support telescopic rod 404 extend outward, pre-pressing the anchor rod onto the clamping part 49 from opposite directions to prevent the anchor rod from rolling or shifting before subsequent clamping. Subsequently, the first sliding base 451 of the first moving clamping component 45 drives the first sliding clamping block 452, and the second sliding base 471 of the second moving clamping component 47 drives the second sliding clamping block 472. Under the push of their respective drive mechanisms, preferably hydraulic cylinders or pneumatic cylinders, they slide closer to the corresponding first fixed clamping component 44 and second fixed clamping component 46, respectively. During this process, the first support telescopic rod 402 and the second support telescopic rod 404 retract synchronously, making room for the final clamping of the sliding clamping block and avoiding interference with the anchor rod. The clamping action is completed when the clamping portion 49 between the first sliding clamping block 452 and the first fixed clamping component 44 is fully in contact with the anchor rod surface, and the clamping portion 49 between the second sliding clamping block 472 and the second fixed clamping component 46 is also fully in contact with the anchor rod surface. At this time, the clamping thread 40 on the clamping portion 49 is embedded in the anchor rod surface, forming a double lock on the axial and radial degrees of freedom of the anchor rod, ensuring that the anchor rod will not experience axial movement or radial wobble when subjected to subsequent diameter reduction forces.

[0079] IV. Diameter Reduction and Chamfering Stage

[0080] After clamping, the power unit 2 is activated, outputting driving force to the diameter reduction base 51, driving the entire diameter reduction device 5 to smoothly slide and feed along the sliding component 11 on the frame 1 towards the clamping device 4. The end of the anchor rod to be processed first enters the diameter reduction pipe 52 and passes through the diameter reduction assembly 53 inside it. The end of the anchor rod first passes through the diameter reduction section 54, which has a tapered inner hole structure, and its inner diameter gradually decreases from the original diameter to the target diameter along the direction of the anchor rod's entry. Under the squeezing action of the tapered hole wall, the end of the anchor rod undergoes radial compressive plastic deformation, and the outer diameter is uniformly reduced to the preset size. After the diameter reduction is completed, the end of the anchor rod continues to move forward with the feed of the diameter reduction device 5, and then enters the chamfered section 55 adjacent to the diameter reduction section 54. The inner wall of the chamfered portion 55 is provided with a conical surface or arc-shaped transition surface with a preset angle, typically 15° to 45°. When the edge of the anchor rod end that has completed the diameter reduction contacts this conical surface, under the action of axial extrusion force, the metal material at the sharp edge of the end undergoes localized flow and rolling to form a smooth and flat chamfered structure. This process is a cold extrusion forming method without cutting, producing no chips and achieving high material utilization. Thus, the anchor rod completes both the diameter reduction and chamfering processes simultaneously in a single continuous feed stroke, without the need for intermediate stops or re-clamping.

[0081] V. Resetting and Material Collection Stage

[0082] After processing, the power unit 2 reverses its drive, causing the reducing base 51 and the reducing pipe 52 to slide in the opposite direction along the frame 1, returning the reducing device 5 to its initial position. Then, the clamping device 4 performs a releasing action: the first sliding base 451 and the second sliding base 471 respectively drive the first sliding clamping block 452 and the second sliding clamping block 472 to slide away from their corresponding fixed clamping components, causing the clamping part 49 to disengage from the anchor rod surface. Simultaneously, the first support telescopic rod 402 and the second support telescopic rod 404 fully retract, releasing the preload on the anchor rod. The processed anchor rod, under its own weight, falls from the clamping device 4, passes through the material passage 13 on the frame 1, is guided by the receiving port 71, and falls into the receiving component 72, completing the finished product collection.

[0083] VI. Continuous Cycle

[0084] While the above-mentioned reset and material collection actions are being performed or completed, the feeding device 8 and the infeed device 6 have begun to transport the next anchor rod to be processed. After the clamping device 4 is fully reset to the clamping state, the next anchor rod immediately enters the clamping device 4, and the above-mentioned complete cycle of pre-compression, clamping, processing, reset, and material collection is repeated to achieve continuous automated production.

[0085] The automated cyclic timing control logic: The entire equipment operation process is fully automatically controlled by a programmable logic controller (PLC). Each action—the lifting action of the feeding assembly 81, the conveying action of the conveying assembly 82, the positioning action of the sliding feed plate 61, the extension and retraction of the first and second support telescopic rods 402 and 404, the clamping and releasing actions of the first and second sliding clamping blocks 452 and 472, the feeding and retraction actions of the diameter reduction device 5 driven by the power unit 2, and the collection action of the receiving device 7—is sequentially connected according to a preset timing logic. The start and stop of each action are monitored in real time by sensors such as proximity switches, pressure sensors, and limit switches to ensure accurate and smooth operation between devices, avoiding collisions or idling, thereby achieving efficient, stable, and fully automated integrated processing of anchor bolt end diameter reduction and chamfering.

[0086] Although the present invention has been described in detail above with reference to preferred embodiments, those skilled in the art will understand that various modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the invention. For example, the type of hinge, the specific form of the locking device, and the selection of materials can all be adjusted according to actual needs. Therefore, the scope of protection of the present invention should be defined by the content of the appended claims.
