Description

Technical Field

[0001] This utility model relates to a support roller for rods and rod processing equipment, belonging to the technical field of metal processing equipment. Background Technology

[0002] An anchor bolt is a tension member that penetrates deep into the ground. One end is connected to the engineering structure, and the other end extends into the ground, providing support by being fixed in the soil. Anchor bolt processing involves multiple steps, including chamfering, marking, thread rolling, and heat-shrink corrosion protection. For example, Chinese utility model patent CN213827524U discloses an anchor bolt processing system, including a chamfering machine, a laser marking machine, a thread rolling machine, and multiple support frames. A conveying mechanism is provided between adjacent support frames. A storage rack is fixed to the top surface of the support frame. The storage rack includes guide rods and stops at the ends of the guide rods. The guide rods are arranged at an angle, with a high end and a low end, and the stops are located at the low end. Anchor bolts (i.e., anchor rods) placed on the storage rack roll down from the high end of the guide rod to the low end until they stop at the stop. Subsequent anchor bolts roll down sequentially until they stop at the previous anchor bolt. A feeding mechanism is provided between the conveying mechanism and the support frame on the same side. The feeding mechanism includes a drive telescopic mechanism and a feeding rod fixed to the top of the drive telescopic mechanism. The feeding rod is also arranged at an angle, with its high end fixed to the top of the drive telescopic mechanism and its low end fixed to a stop bar. In use, the drive telescopic mechanism controls the feeding rod to rise, lifting an anchor bolt on the storage rack. The anchor bolt rolls down the feeding rod until it stops against the stop bar. Then, the drive telescopic mechanism controls the feeding rod to descend, placing the anchor bolt onto the drive wheel of the conveying mechanism, thus realizing the feeding of the anchor bolt.

[0003] For example, Chinese invention patent application CN113320739A discloses an automatic heat shrink production line for anchor bolts, which includes a feeding unit, a heat shrink unit, and a receiving unit. The feeding unit and the receiving unit both include a frame, and the frame includes multiple support rods (i.e., guide rods). The support rods are arranged at an angle so that the anchor bolts (i.e., anchor rods) roll down from the high end to the low end along the support rods. A limit block is fixed at the low end to limit the anchor bolts.

[0004] Therefore, it is evident that the feeding, unloading, and transfer mechanisms in existing anchor bolt processing equipment generally employ inclined guide rods. Since anchor bolts are heavy metal components, they possess a certain speed as they roll down the guide rod to the lower end, causing them to collide with the stop blocks and generate significant noise. When multiple anchor bolts are supported simultaneously on the guide rod, the later anchor bolts will collide with the previous one after rolling into position, similarly generating considerable noise.

[0005] In fact, this problem exists not only in the mechanical field but also in the processing of other components such as steel pipes and solid round steel bars. To address this, Chinese utility model patent CN218230430U discloses a noise reduction mechanism and production line. The noise reduction mechanism includes several speed-reducing components arranged along a slide rail. These speed-reducing components are cams. A mounting plate is vertically fixed to the lower surface of the slide rail. The cams are rotatably mounted on the mounting plate via a rotating shaft, with a portion of the cam protruding from the upper surface of the slide rail. Below the slide rail, corresponding to each cam, is an elastic element. This elastic element includes a guide sleeve, a guide rod, a spring, and a limiting nut. The guide sleeve is fixed to the mounting plate, the guide rod passes through the guide sleeve, and the front end of the guide rod has a step. The spring is sleeved on the guide rod, with both ends abutting against the step and the guide sleeve. The limiting nut is fixed to the tail end of the guide rod. The guide rod abuts against the cam under the action of the spring. When the steel pipe rolls to the position of the cam, its speed will decrease due to the resistance of the cam. The cam rotates to the bottom of the slide under the pressure of the steel pipe. During the rotation of the cam, the guide rod moves under the pressure of the spring, which further compresses the spring. After the steel pipe passes the cam, the guide rod returns to its original position under the action of the spring, which in turn pushes the cam to its original position.

[0006] The cam and elastic element in the noise reduction mechanism mentioned above can be applied to the guide rod of the rod processing equipment. Of course, the guide rod can also be set as a guide plate with a certain width. The guide rod and the guide plate can be collectively referred to as the support roller. However, the structure of the elastic element in the noise reduction mechanism is relatively complex. The rotational motion of the cam needs to be converted into the linear motion of the guide rod, and then the guide rod compresses the spring. There are many parts, the assembly operation is troublesome, and there is friction between the cam and the guide rod during use. The parts are easy to wear and the replacement frequency is high, which increases the cost of use. Utility Model Content

[0007] The purpose of this utility model is to provide a support roller frame for rods, so as to solve the problems of complicated assembly operation, easy wear of parts, high replacement frequency and high use cost when the elastic element in the existing noise reduction mechanism is applied to the support roller frame for rods due to the relatively complex structure of the elastic element; the purpose of this utility model is also to provide a rod processing equipment to solve the above problems.

[0008] To achieve the above objectives, the support roller for the rod in this utility model adopts the following technical solution:

[0009] A support roller frame for rods includes a top wall, a connecting wall connected to the top wall and extending downward, and a bottom wall connected to the connecting wall and located below the top wall. The top wall is inclined to allow the rod to roll down from its high end to its low end. A rod limiting structure is provided at the low end of the top wall. The support roller frame also includes a speed reducer. One end of the speed reducer near the high end of the top wall is hinged to the connecting wall or below the top wall, and the other end is overhanging and has a spring between it and the bottom wall. Positioning pins or positioning grooves for positioning the ends of the springs are respectively provided on the speed reducer and the bottom wall. An opening is provided on the top wall at a position corresponding to the speed reducer. The speed reducer has a protrusion that passes through the opening and protrudes from the upper surface of the top wall under the action of the spring. The distance between the speed reducer and the bottom wall is such that the protrusion can rotate to be flush with the upper surface of the top wall when squeezed by the rod.

[0010] The beneficial effects of the above technical solution are as follows: This utility model is an invention that omits elements, eliminating components such as guide rods, guide sleeves, and limiting nuts in the prior art, allowing the spring to be directly set between the overhanging end of the reducer and the bottom wall. Furthermore, positioning posts or positioning grooves for positioning the spring end are provided on the reducer and the bottom wall, which facilitates the installation and deformation of the spring, simplifies the structure, and makes assembly and operation simple. Moreover, the reducer directly compresses and deforms the spring when rotating, eliminating wear parts, reducing replacement frequency, and lowering usage costs.

[0011] Furthermore, the support frame includes at least two support beams arranged in parallel at intervals. Each support beam has the aforementioned top wall, connecting wall, and bottom wall. Multiple speed reduction components and springs corresponding to the speed reduction components are installed at intervals along the length direction on each support beam. An opening corresponding to the speed reduction component is opened on the top wall of each support beam.

[0012] Furthermore, multiple speed reduction components are arranged at equal intervals on each support beam.

[0013] Furthermore, the spacing between adjacent speed reduction components on each support beam gradually decreases from the high end to the low end of the support beam.

[0015] Furthermore, the elastic element includes a buffer block that is slidably mounted on the limiting block or the limiting rod, the buffer block having a contact surface for contacting the rod, and the elastic element also includes a buffer spring that is mounted on the end face of the buffer block on the side opposite to the contact surface and between the limiting block or the limiting rod.

[0016] Furthermore, the support beam is made of a hollow rectangular tube and has two connecting walls that are vertically connected between the top and bottom walls.

[0017] Furthermore, the reducer has a wedge-shaped block structure, and the projection of the reducer in a plane perpendicular to its own rotation axis is triangular. The reducer has a first side, a second side, and a third side connected in sequence at an included angle. The included angle formed by the first side and the second side is hinged to the connecting wall or below the top wall. The spring is set between the second side and the bottom wall, and the second side is provided with a positioning post or positioning groove. The included angle formed by the first side and the third side constitutes the protrusion.

[0018] Furthermore, a positioning groove is provided on the second side, and a positioning post is provided on the bottom wall.

[0019] To achieve the above objectives, the rod processing equipment of this utility model adopts the following technical solution:

[0020] A rod processing device includes a feeding mechanism and a discharging mechanism. Both the feeding mechanism and the discharging mechanism include a support roller. The support roller of at least one of the feeding mechanism and the discharging mechanism includes a top wall, a connecting wall connected to the top wall and extending downward, and a bottom wall connected to the connecting wall and located below the top wall. The top wall is inclined to allow the rod to roll down from the high end to the low end of the top wall. A rod limiting structure is provided at the low end of the top wall. The support roller also includes a deceleration component. One end of the deceleration component near the high end of the top wall is hinged to the connecting wall or below the top wall, and the other end is overhanging and has a spring between it and the bottom wall. Positioning pins or positioning grooves for positioning the ends of the springs are respectively provided on the deceleration component and the bottom wall. An opening is provided on the top wall at a position corresponding to the deceleration component.

The distance between the deceleration component and the bottom wall is such that the protrusion can rotate to be flush with the upper surface of the top wall when squeezed by the rod.

[0021] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, which further limits the structure of the support roller frame. The support roller frame eliminates the guide rod, guide sleeve, limit nut and other components in the prior art, so that the spring is directly set between the overhang end of the deceleration component and the bottom wall. Furthermore, the deceleration component and the bottom wall are respectively provided with positioning pins or positioning grooves for positioning the end of the spring, which facilitates the installation and deformation of the spring.

[0041] In view of the technical problems existing in the prior art, the basic concept of this utility model is to eliminate the complex guide rod, guide sleeve, limit nut and other components in the prior art, so that the spring is directly set between the overhanging end of the reducer and the bottom wall, and the spring is directly compressed and deformed when the reducer rotates, which simplifies the structure, facilitates assembly, and reduces the number of wear parts.

[0042] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0043] Example 1 of the rod processing equipment of this utility model:

[0044] like Figure 1 As shown, the rod processing equipment in this embodiment is used to chamfer and mark anchor rods. Therefore, the rod is the anchor rod, and the rod processing equipment is the anchor rod chamfering and marking equipment.

[0045] Specifically, the rod processing equipment includes a chamfering machine 1, a marking machine 2, and a conveying mechanism 4 corresponding to the chamfering machine 1 and the marking machine 2 for conveying the anchor rods. A feeding mechanism 3 is provided on one side of the conveying mechanism 4 corresponding to the chamfering machine 1. The feeding mechanism 3 includes a fixed support roller and a lifting support roller for feeding. The fixed support roller is used to store the anchor rods, and the lifting support roller is used to transfer a single anchor rod on the fixed support roller to the conveying mechanism 4 corresponding to the chamfering machine 1 so as to chamfer the anchor rod.

[0046] A transfer mechanism is provided between the two conveying mechanisms 4 corresponding to the chamfering machine 1 and the marking machine 2 respectively. The transfer mechanism includes a flipping frame 5, a fixed support roller and a lifting support roller for transfer. The flipping frame 5 flips to take out the marked anchor rods and transfer them to the fixed support roller. The lifting support roller is used to transfer a single anchor rod on the fixed support roller to the conveying mechanism 4 corresponding to the marking machine 2 so that the anchor rods can be marked.

[0047] Of course, the rod processing equipment also includes a blanking mechanism (not shown in the figure). In addition to chamfering and marking, the rod processing equipment can also perform multiple processing steps for anchor rods, such as thread rolling and heat shrinking corrosion protection. The blanking mechanism is located at the end of the rod processing equipment. The blanking mechanism includes a turning frame for blanking and a fixed support roller. The turning frame takes out the anchor rod of the last processing step by turning it over and transfers it to the fixed support roller. The fixed support roller can store the processed anchor rod.

[0048] In this embodiment, the fixed support rollers and lifting support rollers used for loading, the fixed support rollers and lifting support rollers used for transfer, and the fixed support rollers used for unloading all include multiple parallel and spaced support beams. Taking loading as an example, as... Figure 2 As shown, the fixed support rollers for feeding include multiple parallel and spaced fixed support beams 6. The specific number of fixed support beams 6 is determined by the specific length of the anchor bolts, but there should be at least two. Each fixed support beam 6 is made of a hollow rectangular tube, thus the fixed support beam 6 has four side walls. (Combined with...) Figure 3 and Figure 4 As shown, the fixed support beam 6 includes a fixed top wall 61, a fixed connecting wall 62 connected to the fixed top wall 61 and extending downward, and a fixed bottom wall 63 connected to the fixed connecting wall 62 and located below the fixed top wall 61. There are two fixed connecting walls 62, which are vertically connected between the fixed top wall 61 and the fixed bottom wall 63. The fixed support beam 6 is arranged at an angle, therefore the fixed top wall 61 is also arranged at an angle, allowing the anchor rod to roll down from the high end to the low end along the upper surface of the fixed top wall 61. The low end of the fixed top wall 61 is provided with a rod limiting structure, specifically a limiting block 7, to prevent the anchor rod from detaching from the fixed support beam 6.

[0049] As the anchor bolt rolls down the fixed top wall 61, it has a certain speed. When it reaches the lower end of the fixed top wall 61, it collides with the limiting block 7, generating considerable noise. Simultaneously, subsequent anchor bolts, after rolling into place, collide with the preceding anchor bolt, also generating significant noise. To address this issue, this invention installs a speed reduction component on the fixed support beam 6. In this embodiment, the speed reduction component has a wedge-shaped block structure, namely the speed reduction block 10. One end of the deceleration block 10, near the high end of the fixed top wall 61, is hinged to the fixed connecting wall 62 via a pin 11. The other end extends out and is provided with a deceleration spring 12 between it and the fixed bottom wall 63. An opening is provided on the fixed top wall 61 at a position corresponding to the deceleration block 10. The deceleration block 10 has a protrusion that passes through the opening and protrudes from the upper surface of the fixed top wall 61 under the action of the deceleration spring 12, so as to obstruct the passing anchor rod and reduce the speed of the anchor rod. At the same time, the distance between the deceleration block 10 and the fixed bottom wall 63 is sufficient to allow the protrusion to rotate to be flush with the upper surface of the fixed top wall 61 when squeezed by the anchor rod, so that the anchor rod can pass smoothly.

[0050] The deceleration block 10 is provided with a positioning groove 101 for positioning the upper end of the deceleration spring 12, and the fixed bottom wall 63 is provided with a positioning post 631 for positioning the lower end of the deceleration spring 12, which facilitates the installation and deformation of the deceleration spring 12. Of course, the distance from the positioning post 631 to the deceleration block 10 is greater than the height of the protrusion protruding from the upper surface of the fixed top wall 61, ensuring that the deceleration block 10 can be fully retracted.

[0051] In this embodiment, the projection of the deceleration block 10 in a plane perpendicular to its own rotation axis is triangular, specifically an acute-angled isosceles triangle. The deceleration block 10 has a first side, a second side, and a third side connected in sequence at an included angle. The included angle formed by the first side and the second side is hinged to the fixed connecting wall 62 by a pin 11. The deceleration spring 12 is disposed between the second side and the fixed bottom wall 63, and the second side is provided with the aforementioned positioning groove. The end of the deceleration block 10 near the third side (i.e., the cantilever end) is heavier, and the hinged end (i.e., the hinged end) is lighter. The weight of the cantilever end of the deceleration block 10 can press down on the deceleration spring 12. At the same time, the positioning groove is located near the third side, which facilitates the opening of the positioning groove. The included angle formed by the first side and the third side constitutes the aforementioned protrusion. The protrusion is triangular in shape, which allows the deceleration block 10 to have a certain amount of rotation in order to completely avoid the anchor rod, thus improving the deceleration effect on the anchor rod.

[0052] It should be noted that during installation and use, to prevent the pin 11 from coming loose, retaining rings or cotter pins should be installed at both ends of the pin 11. Additionally, since the fixed support beam 6 is made of a hollow rectangular tube, to facilitate the installation of the positioning post 631, the positioning post 631 can be a small cylinder. During installation, the small cylinder is inserted into the fixed support beam 6 through the opening on the fixed top wall 61, and then fixed to the fixed bottom wall 63 by welding or bonding. Then, the deceleration spring 12 is installed, with its lower end fitted onto the positioning post 631 for positioning. Finally, the deceleration block 10 is installed, with its positioning groove aligned with the upper end of the deceleration spring 12. No further fixing is required between the deceleration spring 12, the positioning post 631, and the deceleration block 10.

[0053] In this embodiment, multiple deceleration blocks 10 and deceleration springs 12 corresponding to each deceleration block 10 are installed at intervals along the length direction on the fixed support beam 6. The multiple deceleration blocks 10 are arranged at equal intervals, and the fixed top wall 61 has openings corresponding to each deceleration block 10. In this way, the anchor rod can achieve multi-stage deceleration during the rolling process, ensuring that the speed is not too high when it reaches the lower end of the fixed top wall 61.

[0054] Furthermore, the limiting block 7 is equipped with an elastic element for contacting the anchor rod, to buffer the first anchor rod that rolls to the lower end and prevent direct collision between the anchor rod and the limiting block 7, thus avoiding excessive noise. Specifically, the elastic element includes a buffer block 13 slidably mounted on the limiting block 7, the buffer block 13 having a contact surface for contacting the anchor rod, and the elastic element also includes a buffer spring 14 mounted between the end face of the buffer block 13 facing away from the contact surface and the limiting block 7.

[0055] Specifically, the limiting block 7 is a hollow block with an opening on its side wall near each deceleration block 10. The buffer block 13 is slidably fitted into this opening. A positioning post (refer to positioning post 631 for the positioning post arrangement) is provided on the side wall of the limiting block 7 away from each deceleration block 10. A positioning groove is also provided on the buffer block 13 to position the two ends of the buffer spring 14. When the anchor rod rolls down to the lower end of the fixed top wall 61, it compresses the buffer block 13, further reducing the speed of the anchor rod and minimizing noise generation.

[0056] Combination Figure 2 , Figure 5 and Figure 6As shown, the lifting support roller frame for loading also includes multiple parallel and spaced lifting support beams 8. The specific number of lifting support beams 8 is determined by the specific length of the anchor rod, with a minimum of two. The lifting support beams 8 are also made of hollow rectangular tubes. Therefore, the lifting support beam 8 includes a lifting top wall 81, a lifting connecting wall 82 connected to the lifting top wall 81 and extending downward, and a lifting bottom wall 83 connected to the lifting connecting wall 82 and located below the lifting top wall 81. There are two lifting connecting walls 82, which are vertically connected between the lifting top wall 81 and the lifting bottom wall 83. The lifting support beam 8 is also arranged at an angle, so the lifting top wall 81 is also arranged at an angle, allowing the anchor rod to roll down from the high end to the low end along the upper surface of the lifting top wall 81. The low end of the lifting top wall 81 is provided with a rod limiting structure, specifically a limiting rod 9, to prevent the anchor rod from coming out of the lifting support beam 8.

[0057] The upper end of the lifting support beam 8 is connected to the telescopic rod of the lifting mechanism 15. The lifting mechanism 15 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, which controls the up and down movement of the lifting support beam 8. When the lifting support beam 8 moves upward, it can lift an anchor rod at the upper end of the fixed support roller. Then, under its own weight, the anchor rod rolls down the lifting support beam 8 from the upper end to the lower end until it stops against the limit rod 9. Then, the lifting mechanism 15 controls the lifting support beam 8 to move downward, so that the anchor rod can be placed on the conveying mechanism 4 corresponding to the chamfering machine 1, and then the chamfering process can be performed.

[0058] To prevent noise caused by the anchor bolt colliding with the limiting rod 9 when it rolls to the lower end, and to prevent noise caused by the subsequent anchor bolt colliding with the previous anchor bolt after it rolls to the position, multiple deceleration blocks 10 and deceleration springs 12 are also installed on the lifting support beam 8. The installation and arrangement of the deceleration blocks 10 and deceleration springs 12 are the same as those on the fixed support beam 6. At the same time, buffer blocks 13 and buffer springs 14 are installed on the limiting rod 9. The installation method is the same as that on the limiting block 7, and will not be repeated here.

[0059] The specific structures of the fixed support rollers and lifting support rollers used for transfer are the same as those used for loading and lifting support rollers. The specific structure of the fixed support rollers used for unloading is also the same as that used for loading, so it will not be repeated here.

[0060] In summary, the deceleration structure for anchor bolt rolling in this utility model eliminates the need for components such as guide rods, guide sleeves, and limiting nuts found in existing technologies. The spring is directly positioned between the overhanging end of the deceleration block and the bottom wall. Furthermore, positioning structures for locating the spring end are provided on both the deceleration block and the bottom wall, facilitating spring installation and deformation. This simplifies the structure, simplifies assembly, and allows the deceleration block to directly compress and deform the spring during rotation. The absence of wear parts reduces replacement frequency and lowers operating costs.

[0061] Example 2 of the rod processing equipment of this utility model:

[0062] like Figure 7 As shown, unlike Embodiment 1, the spacing between adjacent deceleration blocks 10 on the fixed support beam 6 gradually decreases from the high end to the low end of the fixed support beam 6, thus increasing the deceleration effect as the beam rolls downwards. Of course, the arrangement of the deceleration blocks on the lifting support beam can also be configured in the same way.

[0063] Example 3 of the rod processing equipment of this utility model:

[0064] like Figure 8 As shown, unlike Embodiment 1, a downwardly extending ear plate 84 is fixed to the lower surface of the lifting top wall 81 of the lifting support beam 8, and the end of the deceleration block 10 near the high end of the lifting top wall 81 is hinged to the ear plate 84, that is, hinged below the lifting top wall 81. Of course, the structure of the fixed support beam and the hinge method of the deceleration block can be the same.

[0065] Example 4 of the rod processing equipment of this utility model:

[0066] like Figure 9 As shown, unlike Embodiment 1, the fixed support beam 6 is made of U-shaped channel steel, with the channel opening facing laterally. In this case, the fixed support beam 6 also includes a fixed top wall 61, a fixed connecting wall 62 connected to the fixed top wall 61 and extending downwards, and a fixed bottom wall 63 connected to the fixed connecting wall 62 and located below the fixed top wall 61. There is only one fixed connecting wall 62, which is vertically connected between the fixed top wall 61 and the fixed bottom wall 63. Of course, the lifting support beam can also be made of U-shaped channel steel. In other embodiments, the fixed support beam and the lifting support beam can also be made of I-beams or H-beams; any component with a top wall, connecting wall, and bottom wall can be considered.

[0067] Example 5 of the rod processing equipment of this utility model:

[0068] like Figure 10As shown, unlike the above embodiments, the fixed support roller frame in this embodiment is not in the form of multiple parallel spaced fixed support beams, but includes a support roller plate 16. The support roller plate 16 is arranged at an angle and forms the top wall of the support roller frame. Multiple parallel L-shaped fixing rods 17 are fixed to the lower surface of the support roller plate 16. The two side walls of the L-shaped fixing rods 17 respectively form the connecting wall and bottom wall of the support roller frame. Multiple deceleration blocks 10 are installed on each L-shaped fixing rod 17. Corresponding openings are formed on the support roller plate 16. A deceleration spring 12 is provided between the deceleration block 10 and the bottom wall of the L-shaped fixing rod 17. A limit rod 9 is fixed at the lower end of the support roller plate 16, extending laterally. Multiple buffer blocks 13 and buffer springs are installed on the limit rod 9.

[0069] In this embodiment, the length of the support roller 16 must be less than the length of the anchor rod so that both ends of the anchor rod can extend to the outside of the support roller 16, facilitating the lifting support beam to raise the ends of the anchor rod and realize the transfer of the anchor rod. The structures of the fixed support roller for transfer and the fixed support roller for unloading can be the same as those of the fixed support roller in this embodiment.

[0070] In other embodiments of the rod processing equipment: the rod can also be a steel pipe or a solid round steel bar. In this case, the rod processing equipment is a steel processing equipment, such as a processing equipment for cutting and grinding steel pipes or solid round steel bars.

[0071] In other embodiments of the rod processing equipment: when the rod processing equipment has only one processing step, the rod processing equipment does not include a transfer mechanism, but only a loading mechanism and a unloading mechanism. In this case, the loading mechanism and the unloading mechanism can be the same as the loading mechanism and the unloading mechanism in Embodiment 1, or only one of the mechanisms can be the same as in Embodiment 1.

[0072] In other embodiments of the rod processing equipment: whether it is a fixed support beam, a lifting support beam, or an L-shaped fixed rod under the support roller, threaded holes can be machined on the bottom wall of the support roller frame and screws can be installed. The head of the screw is located below the bottom wall, the shank of the screw is short, and the shank extends above the bottom wall to form a positioning post.

[0073] In other embodiments of the rod processing equipment: regardless of the type of support roller, if the wall thickness of the bottom wall of the support roller allows, a positioning groove can be machined on the bottom wall to limit the lower end of the deceleration spring.

[0074] In other embodiments of the rod processing equipment: the deceleration component can be a rectangular block structure, in which one end of the deceleration block is hinged to the connecting wall or below the top wall in the length direction, and the other end is suspended and a spring is provided between it and the bottom wall.

[0075] In other embodiments of the rod processing equipment: the speed reducer can also be a rod-shaped structure.

[0076] In other embodiments of the rod processing equipment: regardless of the shape of the deceleration component, a positioning post can be set on the deceleration component to position the upper end of the deceleration spring. Of course, it is necessary to ensure that the distance between the positioning post and the bottom wall is sufficient for the protrusion of the deceleration component to rotate to be flush with the upper surface of the top wall. Especially when the positioning post is also set on the bottom wall, it is necessary to ensure that the distance between the two positioning posts is sufficient for the rotation stroke of the deceleration component.

[0077] In other embodiments of the rod processing equipment: the limiting rod on the lifting support beam can be replaced with a limiting block.

[0078] In other embodiments of the rod processing equipment: the elastic element on the limiting block or limiting rod can also be an elastic rubber pad.

[0079] In other embodiments of the rod processing equipment: the elastic element may no longer be provided on the limiting block or limiting rod, and the rod is decelerated during the rolling process only by the deceleration element.

[0080] The embodiment of the support roller for rods in this utility model is as follows: the specific structure of the support roller for rods is the same as that of the fixed support roller or lifting support roller in any embodiment of the rod processing equipment described above, and will not be repeated here.

[0081] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
