Description

Technical Field

[0001] This utility model relates to the field of anchor bolt processing technology, specifically to an anchor bolt flanging device. Background Technology

[0002] Slotted pipe anchors are a type of anchor that provides full-length anchoring. They are made of cold-rolled steel strip and have a narrow slot along their longitudinal direction. During installation, the anchor is driven into a borehole smaller than its outer diameter. The slot is compressed and contracts, generating radial pressure on the borehole wall, causing the anchor to fit tightly against the borehole wall and achieving full-length anchoring. One end of the slotted pipe anchor is welded with a retaining ring, which secures the anchor mesh. The retaining ring and a support plate further secure the anchor mesh, connecting loose rock particles together, increasing the integrity and stability of the surrounding rock, preventing small rock fragments from falling, and acting as a surface protector.

[0003] However, in ore bodies with fractured and loose rock masses, and in damp and corrosive mines, the retaining rings and trays may weather and fall off due to excessive impact force during anchor bolt installation and the effects of weathering and corrosion, posing certain safety hazards.

[0004] Therefore, it is necessary to perform a flange treatment on the anchor rod, turning the steel strip extending beyond the welded ring of the anchor rod outward and wrapping it around the welded ring. In this way, even if the retaining ring becomes loose, it will be fixed by the flange of the anchor rod and will not fall off.

[0005] However, existing anchor bolting machines can only produce ordinary anchor bolts without flanges. Flanging requires manual labor, which results in high labor costs and low production efficiency, making it difficult to meet demand.

[0006] Therefore, it is necessary to study an anchor bolt flange device. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide an anchor bolt flanging device, which can effectively solve the problem that the anchor bolt flanging process relies on manual labor, resulting in low quality and efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An anchor bolt flanging device includes an anchor bolt transport device and a flanging stamping device; The anchor bolt transport device is used to transport the spaced anchor bolts forward intermittently. The flange stamping device is located on the side of the anchor bolt transport device and on the side where the weld ring end of the anchor bolt is located; The flanging stamping device includes a mold frame, an upper clamping clamp, a lower clamping clamp, a stamping head, a lifting cylinder, and a stamping cylinder; The mold frame has a U-shaped clearance facing the weld ring end of the anchor rod, so that the weld ring end of the anchor rod can pass through the mold frame; The upper clamping clamp is fixedly mounted on the mold frame and located above the clearance opening; The lower clamp is vertically slidably mounted on the mold frame and located below the clearance opening. The lower part of the lower clamp is fixedly connected to the telescopic end of the lifting cylinder. The upper clamping clamp and the lower clamping clamp each have a clamping groove on their opposite sides that matches the shape of the anchor rod. The stamping head is conical and is horizontally slidably mounted on the frame. The tail of the stamping head is fixedly connected to the telescopic end of the stamping cylinder. When the lifting cylinder operates, causing the lower clamping clamp to lift towards the upper clamping clamp and clamp and fix the welded ring end of the anchor rod in the clearance opening, the punching head is directly opposite the end of the welded ring end and can punch the end of the welded ring end through the punching cylinder to form a flange.

[0009] Furthermore, the anchor bolt transport device includes a frame, a rotating shaft, a sprocket, and a ring chain; The rotating shaft is rotatably mounted on both the front and rear sides of the frame. The rotating shaft is connected to a stepper motor, which causes the rotating shaft to rotate intermittently to transport the anchor rod forward intermittently. The sprocket is fixedly sleeved on the rotating shaft; the annular chain drive is mounted on the sprocket. A load-bearing beam is fixedly mounted on the frame along the front-to-back direction, and the upper half of the ring chain moves and rests on the load-bearing beam. Several limiting components are fixedly arranged at intervals on the annular chain to ensure that the anchor rods supported on the annular chain are arranged at intervals.

[0010] Furthermore, mounting plates are fixedly connected to both sides of the chain, and the limiting component is mounted on the mounting plates.

[0011] Furthermore, the limiting component includes two limiting plates spaced apart front and rear to form a limiting range, so that the anchor rods are evenly spaced on the chain.

[0012] Furthermore, the limiting plate is inclined along the front-to-back direction, and the two limiting plates are symmetrically arranged in front and back, so that the limiting interval forms a cone shape that is larger at the top and smaller at the bottom.

[0013] Furthermore, both the upper and lower clamping clamps are provided with two sets of clamping grooves along the front-back direction, and the distance between the two sets of clamping grooves corresponds to the distance between two adjacent sets of anchor rods. The stamping head and the stamping cylinder are each arranged in two sets along the front-to-back direction, and the distance between the two sets of stamping heads corresponds to the distance between two adjacent sets of anchor rods.

[0014] Furthermore, the taper of the front stamping head is smaller than that of the rear stamping head.

[0015] The beneficial effects of the above technical solution are: This invention employs an intermittent anchor bolt transport device to transport anchor bolts. A flanging and stamping device is added to the side of the transport device. Each time an anchor bolt completes one cycle forward, the next anchor bolt enters the clearance slot and stops precisely at the corresponding position in the clamping groove. Subsequently, the lifting cylinder operates, causing the lower clamping clamp to lift towards the upper clamping clamp, and driving the anchor bolt upwards. This allows the upper and lower clamping seats to clamp and fix the welded ring end of the anchor bolt. At this time, the stamping head is directly opposite the end of the welded ring, and the stamping cylinder is activated. The stamping head stamps the end of the welded ring, automatically flanging the anchor bolt. This achieves fully automated production of anchor bolt flanging, and the entire flanging process does not affect the original production line's cycle time. It effectively solves the problem of low quality and efficiency in anchor bolt flanging processes due to reliance on manual labor, reducing labor costs and improving the efficiency of continuous production.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: This embodiment aims to provide an anchor bolt flanging device, which is mainly used for the continuous processing of slotted anchor bolts, addressing the problem that the anchor bolt flanging process relies on manual labor, resulting in low quality and efficiency.

[0019] An anchor bolt flange device, such as Figure 1-4 It includes an anchor bolt transport device 1 and a flange stamping device 2. The anchor bolt transport device 1 is set after the welding ring process and is used to transfer the anchor bolts 5 after the welding ring. In the existing process of welding retaining rings, a robot arm is usually used to grab the anchor bolts 5 and put them into the welding machine for welding. After welding is completed, they are stacked and output to the anchor bolt transport device 1, realizing the intermittent output of the anchor bolts 5 from the welding machine to the anchor bolt transport device 1.

[0020] The anchor bolt transport device 1 includes a frame 101, a rotating shaft 102, a sprocket 103, and a ring chain 104. The frame 101 includes at least support legs and a frame body fixed to the support legs, mainly used to provide an installation foundation for other components. Three guide frames 105 are welded to the front end face of the frame 101 at intervals along the left-right direction. The ends of the guide frames 105 extend downward to guide the output anchor bolts 5 to the storage rack of the next process.

[0021] The rotating shaft 102 is rotatably mounted on both the front and rear sides of the frame 101. Specifically, the rotating shaft 102 located at the front end is rotatably mounted on the guide frame 105. The rotating shaft 102 is driven by a stepper motor, which causes the rotating shaft 102 to rotate intermittently, thereby intermittently transporting the anchor rod 5 forward. The stepper motor is not shown in the attached drawings. Its specific installation method and working principle adopt existing technology and will not be described in detail here.

[0022] The sprocket 103 is fixedly sleeved on the rotating shaft 102; the annular chain 104 is driven by the sprocket 103; for ease of display, the annular chain 104 is... Figure 1-4 The original text has been simplified; its specific structure can be found in the reference section. Figure 12 and Figure 13 .

[0023] A load-bearing beam 1011 is fixedly mounted on the frame 101 along the front-to-back direction. The upper half of the ring chain 104 moves and rests on the load-bearing beam 1011, so that when the anchor rod 5 is supported on the ring chain 104, it can receive the support of the load-bearing beam 1011.

[0024] Several limiting components 3 are fixedly installed at intervals on the chain to ensure that the anchor rods 5 supported on the annular chain 104 are arranged at intervals. Specifically, for example... Figure 12 and Figure 13 Mounting plates 4 are fixedly connected to both sides of the chain, and limiting components 3 are mounted on the mounting plates 4. The limiting components 3 include two limiting plates 301 spaced apart front to back, forming a limiting range to limit the anchor rods 5 in the front-back direction, so that the anchor rods 5 are evenly spaced on the chain. The limiting plates 301 are inclined in the front-back direction, and the two limiting plates 301 are symmetrically arranged front to back, so that the limiting range forms a cone shape that is larger at the top and smaller at the bottom.

[0025] The flanging and stamping device 2 is installed on the side of the anchor bolt transport device 1, and is located on the side where the weld ring end of the anchor bolt 5 is located; for example Figure 5-7 The flanging and stamping device 2 includes a mold frame 201, an upper clamping clamp 202, a lower clamping clamp 203, and a stamping head 204. The mold frame 201 has a U-shaped clearance opening 2011 for the welding ring end of the anchor rod 5 to pass through the mold frame 201. The upper clamping clamp 202 is fixedly mounted on the mold frame 201 and located above the clearance opening 2011. The lower clamping clamp 203 is vertically slidably mounted on the mold frame 201 and located below the clearance opening 2011. The lower part of the lower clamping clamp 203 is fixedly connected to the telescopic end of the lifting cylinder 205, and the cylinder body of the lifting cylinder 205 is fixed on the mold frame 201. The upper clamping clamp 202 and the lower clamping clamp 203 each have a clamping groove 2021 on their opposite sides that matches the shape of the anchor rod 5, for clamping and fixing the anchor rod 5. The stamping head 204 is conical and is horizontally slidably mounted on the frame 101. The tail of the stamping head 204 is fixedly connected to the telescopic end of the stamping cylinder 206, and the cylinder body of the stamping cylinder 206 is fixed on the mold frame 201.

[0026] like Figure 8-11 Each time the anchor bolt 5 moves forward for one cycle, the next anchor bolt 5 enters the clearance opening 2011 and stops at the corresponding position in the clamping groove 2021; then the lifting cylinder 205 operates, causing the lower clamping clamp 203 to lift towards the upper clamping clamp 202, and driving the anchor bolt 5 to move upward, so that the upper and lower clamping seats clamp and fix the welded ring end of the anchor bolt 5; at this time, the stamping head 204 is facing the end of the welded ring, the stamping cylinder 206 is started, and the stamping head 204 stamps the end of the welded ring to form a flange.

[0027] In this embodiment, the stamping cycle of the flanging and stamping device 2 is consistent with the intermittent forward cycle of the anchor bolt transport device 1, and they operate alternately. That is, whenever the anchor bolt transport device 1 completes one forward movement, the flanging and stamping device 2 is activated once. It relies on a fixed timing sequence for continuous operation. In other embodiments, a proximity switch can also be set on the mold frame 201. Whenever the anchor bolt 5 enters the clearance opening 2011, the proximity switch will be triggered, thereby triggering the flanging and stamping device 2 to run one cycle. However, the stamping cycle of the flanging and stamping device 2 should be less than or equal to the intermittent forward cycle of the anchor bolt transport device 1 to ensure the continuity of the process cycle.

[0028] Furthermore, such as Figure 5-11 Both the upper and lower clamping clamps 203 have two sets of clamping grooves 2021 along the front-to-back direction. The distance between the two sets of clamping grooves 2021 corresponds to the distance between two adjacent sets of anchor rods 5. The punching head 204 and the punching cylinder 206 are both arranged in two sets along the front-to-back direction. The distance between the two sets of punching heads 204 corresponds to the distance between two adjacent sets of anchor rods 5, so that the flanging punching device 2 has two punching stations, and each anchor rod 5 needs to be punched twice; Figure 6 The taper of the front stamping head 204 is smaller than that of the rear stamping head 204. The stamping head 204 with a larger taper is used for the first stamping, and the stamping head 204 with a smaller taper is used for the second stamping. By forming the stamping in two stages, the success rate of flanging can be improved.
