Description

Technical Field

[0001] The present invention relates to the technical field of flame cutting, and in particular to a raw material cutting device for producing and processing anchor rods. Background Art

[0002] In the process of cutting raw materials for anchor rod production, flame cutting can efficiently complete the cutting task for metal anchor rod materials with larger diameters (such as those exceeding a certain size), while other methods (such as sawing) may be difficult to perform due to equipment limitations.

[0003] However, most existing flame cutting nozzles use a single nozzle for continuous cutting. During long periods of continuous operation, the flame cutting nozzle absorbs a large amount of heat. If heat is not dissipated in a timely manner, the nozzle material may soften or even melt, affecting the cutting effect and shortening the nozzle life. Furthermore, the incision produced by flame cutting is generally rough, and slag may be present on the edges of the anchor material, requiring subsequent polishing to achieve the desired surface quality. Summary of the Invention

[0004] In order to overcome the shortcomings of the flame cutting nozzle softening or even melting the solution when it is continuously working, and the need to grind the incision after flame cutting, the present invention provides a raw material cutting device for anchor rod production and processing.

[0005] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry out pin connection respectively.

[0006] Furthermore, the pushing assembly includes a push rod, which is rotatably connected to the workbench and is squeezed into engagement with the annular frame. A first torsion spring is fixedly connected between the push rod and the workbench, and the rotating frame is fixedly connected to a toggle tooth. The push rod drives the rotating frame to rotate through the toggle tooth, thereby driving the spray gun to rotate.

[0007] Furthermore, a movable groove for the push rod is opened on one side of the annular frame close to the first torsion spring, and a wedge-shaped surface is opened on one side of the annular frame close to the movable groove, and the annular frame is squeezed and fitted with the push rod through the wedge-shaped surface.

[0008] Furthermore, the pushing assembly also includes a fixed block for limiting the push rod, and the fixed block is fixedly connected to the workbench.

[0009] Furthermore, it also includes a first rotating rod, which is rotatably connected to a side of the annular frame close to the movable groove. A rubber pad is fixed to a side of the first rotating rod close to the toggle tooth, and the rubber pad is used to fix the toggle tooth.

[0010] Furthermore, a second torsion spring is included, and the second torsion spring is fixed between the first rotating rod and the annular frame.

[0011] Furthermore, a friction plate is also included. The friction plate is fixed in the annular frame. The friction plate and the shifting teeth are frictionally matched to increase the rotational resistance between the annular frame and the rotating frame.

[0012] Furthermore, it also includes a second rotating rod symmetrically distributed along the rotating axis, the second rotating rod is fixed to the rotating axis, the second rotating rod is rotatably connected to a connecting rod, the workbench is fixed to a guide rail, the guide rail is slidably connected to a sliding frame for pressing the raw materials for anchor rod production, and the sliding frame is rotatably connected to the connecting rod.

[0013] Furthermore, a guide frame is included, which is placed in a placement groove of the workbench and is fixed to the workbench by at least two screws.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The present invention drives the annular frame to rotate counterclockwise with the rotating shaft as the center through the cylinder, and intermittently realizes the effect of automatically switching the spray gun. During the switching process, the grinding ring moves synchronously with the rotating frame. When rotating counterclockwise with the rotating shaft as the center, the grinding ring can grind the end face of the incision of the raw material for anchor rod production, avoiding the phenomenon of slag hanging on the edge of the incision.

[0016] The present invention limits the rotating frame by toggling the teeth through the first rotating rod, so that the rotating frame is automatically locked when the spray gun cuts the anchor rod, avoiding the spray gun being affected by external forces when cutting the raw materials for anchor rod production and causing the spray gun to shift, resulting in deviation of the cutting position of the spray gun.

[0017] The present invention appropriately increases the resistance between the annular frame and the rotating frame by increasing the friction plate, so as to prevent the push rod from driving the shifting gear to rotate and the rotating frame to shift during the resetting process of the rotating frame, causing the spray gun to rotate after switching.

[0018] When the spray gun is switched, the second rotating rod is driven to rotate by the rotating shaft, so that the sliding frame presses the raw material downward to prevent the raw material from moving randomly when the grinding ring is grinding the raw material cut. When the ring frame is reset, the sliding frame is pulled open to facilitate the movement of the raw material for the next step of cutting or removal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1: A device for cutting raw materials for anchor rod production and processing, such as Figures 1-4 As shown, it includes a workbench 101, a placement slot is opened on the top of the workbench 101, the placement slot is used to place the anchor rod production raw materials, a fixed rod 102 is fixedly connected to the lower right side of the workbench 101, the front side of the fixed rod 102 is rotatably connected to the cylinder 103, the telescopic end of the cylinder 103 is rotatably connected to the annular frame 104, the upper right side of the workbench 101 is rotatably connected to the rotating shaft 1041, the front side of the rotating shaft 1041 is fixedly connected to the annular frame 104, the annular frame 104 is rotatably connected to the rotating frame 105, the front side of the annular frame 104 is fixedly connected to the fixed air inlet frame 106, the fixed air inlet frame 106 is rotatably connected to the rotating frame 105 Dynamic connection, six circumferentially distributed spray guns 107 are fixed to the inner side of the rotating frame 105, and an air intake pipe 108 is fixed to the upper side of the fixed air intake frame 106. The rotating frame 105 has an annular air cavity, and the spray guns 107 and the air intake pipe 108 are connected to the air cavity of the rotating frame 105. Six circumferentially distributed partitions are opened in the air cavity of the rotating frame 105. The right side of the partition of the rotating frame 105 is in contact with the left side of the fixed air intake frame 106. The partitions of the rotating frame 105 and the spray guns 107 are alternately distributed. A grinding ring 109 is fixed to the left side of the rotating frame 105. The grinding ring 109 is used to grind the end face of the cut of the raw material for anchor rod production.

[0033] like Figures 5-7 As shown, it also includes a push rod 201, which is rotatably connected to the workbench 101. A movable groove is provided on the front side of the annular frame 104, and the push rod 201 moves in the movable groove. A wedge-shaped surface is provided on the side of the annular frame 104 close to the movable groove. The annular frame 104 is squeezed and fitted with the push rod 201 through the wedge-shaped surface. A first torsion spring 202 is fixed between the push rod 201 and the workbench 101. A fixed block 203 is fixed to the right part of the workbench 101. The fixed block 203 is used to limit the push rod 201 to prevent the push rod 201 from rotating excessively counterclockwise. An annular toggle tooth 204 is fixed to the rotating frame 105. The push rod 201 toggles the rotating frame 105 to rotate relative to the annular frame 104 through the toggle tooth 204, thereby driving the spray gun 107 to rotate.

[0034] The anchor bolt raw material is placed in the placement slot of the workbench 101. Next, gas is introduced into the air inlet pipe 108, which is directed between the two uppermost partitions of the rotating frame 105 and the fixed air inlet frame 106. The uppermost spray gun 107 is activated, and the uppermost spray gun 107 performs a flame cutting on the raw material. To prevent the nozzle from softening or even melting the nozzle material due to continuous operation, thereby improving the cutting effect and extending the nozzle life, it is necessary to switch the spray gun 107 in a timely manner. The specific operation of switching the spray gun 107 is as follows:

[0035] The telescopic rod of the control cylinder 103 is extended to push the annular frame 104 to rotate counterclockwise with the rotating shaft 1041 as the center of the circle. The annular frame 104 drives the rotating frame 105, the fixed air inlet frame 106, the spray gun 107, the air inlet pipe 108 and the toggle gear 204 thereon to rotate counterclockwise synchronously. During the rotation process, the annular frame 104 first gradually loosens the push rod 201, so that the first torsion spring 202 in the stored force state adaptively returns to its position, driving the push rod 201 to rotate clockwise until it is stuck in the toggle gear 204. Subsequently, the annular frame 104 continues to drive the components thereon to rotate counterclockwise. In this process, since the push rod 201 limits the toggle gear 204, the toggle gear 204 will also rotate clockwise relative to the annular frame 104 as the annular frame 104 continues to rotate counterclockwise. , the toggle tooth 204 rotates relative to the annular frame 104, driving the rotating frame 105 to rotate clockwise relative to the annular frame 104. The rotating frame 105 drives the spray gun 107 to rotate clockwise, so that the nozzle that has just been flame-cutting turns away from the air inlet pipe 108 to cool down, and the next nozzle turns to the air inlet pipe 108 to prepare for flame cutting. Then the telescopic rod of the cylinder 103 is controlled to shorten and pull the annular frame 104 to rotate clockwise and reset. The annular frame 104 drives the rotating frame 105, the fixed air inlet frame 106, the spray gun 107, the air inlet pipe 108 and the toggle tooth 204 thereon to rotate clockwise and reset synchronously, so that the push rod 201 is disengaged from the toggle tooth 204, and the annular frame 104 squeezes the push rod 201 to rotate counterclockwise until it contacts the fixed block 203, and the first torsion spring 202 returns to the stored state.

[0036] By repeating this process, the effect of automatically switching the spray gun 107 can be achieved intermittently, and during the switching process, the grinding ring 109 moves synchronously with the rotating frame 105. When rotating counterclockwise with the rotating shaft 1041 as the center, the grinding ring 109 can grind the end face of the incision of the anchor rod production raw material to avoid slag on the edge of the incision.

[0037] Example 2: Based on Example 1, Figure 8 and Figure 9 As shown, it also includes a first rotating rod 301, which is rotatably connected to the side of the annular frame 104 close to the movable groove. A second torsion spring 302 is fixed between the first rotating rod 301 and the annular frame 104. A friction plate 303 is fixed inside the annular frame 104. The friction plate 303 and the toggle tooth 204 are frictionally engaged to increase the rotational resistance between the annular frame 104 and the rotating frame 105. A rubber pad 304 is fixed to the side of the first rotating rod 301 close to the toggle tooth 204. The rubber pad 304 is used to fix the toggle tooth 204.

[0038] In order to prevent the spray gun 107 from being displaced by external forces when cutting the raw materials for anchor rod production, resulting in the deviation of the cutting position of the spray gun 107, the specific protective measures are as follows: during cutting, the first rotating rod 301 cooperates with the toggle tooth 204 to firmly lock the rotating frame 105, thereby preventing the spray gun 107 from being displaced when cutting the anchor rod. When the spray gun 107 needs to be switched, the rotating frame 105, the toggle tooth 204 and the first rotating rod 301 first contact the push rod 201 during the process of swinging downward counterclockwise, and then the first rotating rod 301 is forced to rotate clockwise, and the rubber pad 304 on the first rotating rod 301 is disengaged from the toggle tooth 204, the rotating frame 105 is unlocked, and the second torsion spring 302 is The toggle teeth 204 are pushed by the push rod 201 to rotate the rotating frame 105, and the spray gun 107 is switched. When the rotating frame 105 and the spray gun 107 are switched, the rotating frame 105 is reset as the rotating frame 105 swings upward clockwise, and finally the first rotating rod 301 is disengaged from the toggle teeth 204, and the second torsion spring 302 is deformed by the force, thereby driving the first rotating rod 301 to reset, and the rubber pad 304 on the first rotating rod 301 is re-engaged in the toggle teeth 204 to complete the locking. In this way, the toggle teeth 204 are driven by the first rotating rod 301 to limit the rotating frame 105, so that the rotating frame 105 is automatically locked when the spray gun 107 cuts the anchor rod, preventing the spray gun 107 from rotating and deviating due to external force.

[0039] In order to prevent the push rod 201 from driving the rotating frame 105 to rotate counterclockwise when it contacts the toggle tooth 204 when the rotating frame 105 swings clockwise upward to reset, causing the spray gun 107 to rotate after switching, specific protective measures are as follows: when the push rod 201 pushes the first rotating rod 301 to rotate, the friction between the annular frame 104 and the rotating frame 105 is appropriately increased by the friction plate 303 to prevent the push rod 201 from driving the toggle tooth 204 to rotate and the rotating frame 105 to rotate when the rotating frame 105 resets.

[0040] Example 3: Based on Example 2, Figure 10 As shown, it also includes a second rotating rod 401 symmetrically distributed along the rotating shaft 1041. The second rotating rod 401 is fixedly connected to the rotating shaft 1041. A connecting rod 402 is rotatably connected to the second rotating rod 401. A guide rail 403 is fixedly connected to the top right side of the workbench 101. The guide rail 403 is connected to a sliding frame 404 that slides along the left and right directions. The sliding frame 404 is rotatably connected to the connecting rod 402. The sliding frame 404 is used to press the raw materials for anchor rod production.

[0041] When the annular frame 104 rotates counterclockwise, the rotating shaft 1041 drives the second rotating rod 401 to rotate counterclockwise synchronously. The second rotating rod 401 pushes the sliding frame 404 to slide leftward along the guide rail 403 through the connecting rod 402, so that the sliding frame 404 presses down on the raw material, preventing the raw material from moving randomly when the grinding ring 109 grinds the cut of the raw material; when the annular frame 104 rotates clockwise, the rotating shaft 1041 drives the second rotating rod 401 to rotate clockwise synchronously. The second rotating rod 401 pulls the sliding frame 404 to move rightward along the guide rail 403 through the connecting rod 402, facilitating the movement of the raw material for the next cutting process or removal.

[0042] As Figure 11 shown, it further includes a guiding frame 501. The guiding frame 501 is placed in the placement groove of the workbench 101 and is fixed to the workbench 101 by two front and rear screws 502.

[0043] According to the size of the raw material for anchor rod production, select and replace the guiding frame 501 with the corresponding size. In this way, it can adapt to placing raw materials for anchor rod production of different sizes.

[0044] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made based on the content of the claims of the present invention should be included within the scope of the claims of the present invention.
