Description

Technical Field

[0001] This utility model belongs to the field of fastener processing technology, specifically relating to the feeding mechanism of a double-headed bolt profile straightening device. Background Technology

[0002] In the fastener manufacturing industry, double-ended studs are an important connecting component and are widely used in machinery manufacturing, bridge construction, and pipeline engineering. Especially for double-ended studs with a length-to-diameter ratio of 120mm and above, the processing technology usually includes length cutting, heat treatment (quenching and tempering), bar straightening, threading at both ends, and surface treatment.

[0003] In existing production processes, after raw materials are cut to length, they typically undergo quenching in a heat treatment furnace to achieve the required mechanical strength and hardness. However, due to the relatively long length of the raw materials for double-ended bolts (mostly long strips of round steel or lead screws), the profiles are prone to irregular thermal deformation and bending during high-temperature quenching in a continuous mesh belt furnace. This is due to factors such as their own weight, the friction of the mesh belt, and uneven cooling shrinkage. This bending deformation is particularly pronounced for workpieces with long length-to-diameter ratios.

[0004] Double-ended studs with a bend cannot be used directly. Therefore, after the quenching process, the ends or the entire stud must be straightened. Currently, the industry mostly uses straightening machines for this purpose. However, when conveying the bent double-ended stud profiles after quenching to the straightening device, manual feeding is often used, which is extremely labor-intensive, has poor production continuity, and low efficiency. Because the straightening machines used for the profiles have one or more straightening rollers on each side of the straightening trough, with one side of the straightening roller fixed relative to the other, the straightening of the profile is achieved by driving the straightening roller on the other side to open or close. Existing straightening machines operate continuously. Therefore, if the next profile cannot be fed into the straightening trough in time (and the straightened profile is pushed out of the straightening trough), the profile in the straightening trough will be subjected to more than two straightening roller compressions, resulting in the scrapping of the profile and a reduction in the yield rate. Utility Model Content

[0005] In summary, to overcome the shortcomings of the prior art, this utility model provides a feeding mechanism for a double-headed bolt profile straightening device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a double-headed bolt profile straightening device, comprising a stacking box, a receiving trough, a straightening mechanism, and a control component. The straightening mechanism includes a straightening trough, straightening components respectively disposed on the left and right sides of the straightening trough, and a first driving component for driving the straightening components to move left and right. The receiving trough and the straightening trough are connected by a transition trough. A pushing component for pushing the profiles in the receiving trough forward is disposed at the other end of the receiving trough relative to the transition trough. The stacking box is located on one side of the receiving trough. One end of the stacking box corresponding to the receiving trough is the feeding end. A ramp is provided between the feeding end and the receiving trough. The lower end of the ramp is located above the receiving trough. The feeding end is equipped with a feeding component for pushing the profiles at the bottom of the stacking box out of the stacking box and allowing them to slide down the ramp into the receiving trough. A detection component is provided above the receiving trough for monitoring the presence and height of the profiles in the trough. The detection component, the pushing component, the first driving component, and the feeding component are electrically connected to the control component.

[0007] By adopting the above technical solution, the biggest drawback of traditional manual material feeding is that the physical exertion of workers directly determines the output rhythm of the equipment. In this technical solution, a perfect automated closed loop is formed through the design of centralized material storage in the stacking bin, gravity sliding on the ramp, and forward movement of the pushing component. When the detection component confirms that there is a profile in the receiving trough, the pushing component pushes the profile forward, causing the profiles in the transition trough and straightening trough to move forward. The straightening trough is then filled with an unstraightened profile. (When the next profile is pushed from the receiving trough into the transition trough under the action of the pushing force, the previous profile automatically fills the gap.) When the pushing component resets, the control component controls the first drive component to move the straightening component in the closing direction to complete the straightening action and then separate. After the pushing component resets, the detection component confirms that the receiving trough is empty. The control component then controls the feeding component to push the profile at the bottom of the stacking box out of the stacking box and let it slide down the slope into the receiving trough. Then the above steps are repeated. This continuous flow operation of "replenishing as needed" reduces the downtime waiting time for manual material placement and keeps the straightening mechanism in a fully loaded and highly efficient state, resulting in high production efficiency. Existing straightening mechanisms, due to their continuous operation, if the material is fed into the straightening trough... Delayed material feeding can lead to repeated compression and scrapping of the profile. This technical solution uses a detection component to monitor the presence and height of the profile in the groove in real time, and immediately feeds the signal back to the control component. The control component is electrically connected to the detection component, the pushing component, the first drive component, and the feeding component. Only after the pushing component resets and confirms the new profile to be straightened is in place will the first drive component drive the straightening rollers (the straightening component includes the straightening rollers and the drive unit that drives them) to close (closing means the straightening rollers on both sides are in a relatively close state, compressing and straightening the profile). This… The interlocking mechanism of "feeding new material" and "starting straightening" avoids the ineffective wear of the equipment caused by the no-load pressing of the straightening mechanism due to preset cycle time or open-loop control in the existing technology, or the secondary damage to the straightened profiles in the straightening trough. This ensures the stability of continuous production and the product yield. At the same time, the feeding component is automatically triggered to push the material when the trough is empty, and waits for the material to be pushed when the trough is full, avoiding energy consumption due to idling or material jamming. From the ejection of the material from the bottom of the stacking box to the forward displacement in the receiving trough, the whole process is completed automatically by mechanical components, which greatly reduces the labor intensity of workers and reduces the risk of mechanical pinching injury.

[0008] The present invention further includes: a movable side plate is provided inside the stacking box; the movable side plate is connected to the fixed side of the stacking box by adjusting bolts; the movable side plate is adjusted in position by adjusting bolts to accommodate profiles of different lengths; and an active space is provided between the end of the movable side plate corresponding to the feeding end and the feeding end of the stacking box for the feeding assembly to move.

[0009] By adopting the above technical solution, the position of the movable side plate can be reliably maintained after the adjusting bolts are adjusted to the correct position, preventing displacement due to vibration or thrust during profile feeding and ensuring feeding accuracy. The cooperation between the movable side plate and the adjusting bolts allows the movable side plate to flexibly adapt to double-headed bolt profiles of different lengths, greatly improving the equipment's versatility and stability. This ensures that the profiles remain orderly arranged in the stacking bin, avoiding tilting or jamming due to excessive gaps, thus preventing the "material jamming" phenomenon when they subsequently slide into the receiving trough, improving the stability and reliability of the feeding process. A reserved space between the front end of the movable side plate and the feeding end allows for the movement of the feeding component. No matter how the position of the movable side plate is adjusted, it will never obstruct the movement trajectory of the feeding component, resulting in high stability and smoother operation.

[0010] The present invention further includes: a rotating rod provided above the slope, and a limiting claw provided on the rotating rod to prevent the profile from falling directly into the receiving trough along the slope; the limiting claw includes a connecting end detachably connected to the rotating rod and a limiting claw end for limiting the profile; a second driving assembly for driving the rotating rod to rotate is provided on the outer periphery of the stacking box; the second driving assembly is electrically connected to the control assembly; the second driving assembly drives the limiting claw end to abut or separate from the slope through the rotating rod.

[0011] By adopting the above technical solution, and by setting a controllable rotating limiting claw, the second drive component controls the contact or separation state between the limiting claw end and the ramp, which can accurately intercept and release the falling profile. Compared with waiting for the feeding component to be pushed up and then rolling down the ramp, the profile rolls from the limiting claw end into the receiving trough, greatly shortening the feeding interval time and improving the straightening feeding efficiency. If the double-headed bolt profile directly rushes from the stacking box into the receiving trough along the ramp, it will generate a large kinetic energy impact. This rigid collision not only easily causes the end of the profile to be bumped and damaged, affecting product quality, but also aggravates the vibration and wear of the mechanical structure. In this utility model solution, the limiting claw can effectively block and limit the falling profile. After the profile detaches from the limiting claw, it can fall smoothly into the receiving trough at a low speed, realizing flexibility in the material transfer process and significantly reducing noise, vibration, and equipment damage rate. The limiting claw and rotating rod are detachably connected, and the position of the limiting claw can be adjusted according to different profile specifications and lengths. The adjustment is simple and convenient, and the applicability is strong. The second drive component is electrically connected to the control component, so that the action of the limiting claw can form a tight automated timing with the detection component and the pushing component. The control component controls the second drive component to achieve a fully automatic cycle of "detecting empty space - lifting the claw end to release - detecting the position - pressing down the claw end to stop" based on the detection signal of the profile in the receiving trough. The degree of automation is high and the efficiency is high.

[0012] The present invention further comprises: the feeding assembly including a lower feeding plate and a top feeding plate arranged in a staggered manner, the top feeding plate being located at the upper end of the slope, a movable plate being provided between the lower feeding plate and the top feeding plate, the width of the movable plate being adapted to the distance between the lower feeding plate and the top feeding plate, the width of the movable plate being less than twice the diameter of the profile, and a third driving assembly being provided below the movable plate for driving the movable plate to reciprocate up and down moving the material.

[0013] By adopting the above technical solution, the width of the movable plate is less than twice the diameter of the profile, ensuring that during the upward process, the movable plate can only lift one profile at a time to pass over the top feeding plate and slide into the ramp, while subsequent profiles are blocked at the position of the lower feeding plate. This mechanical "single-section separation" mechanism fundamentally avoids the stacking and jamming problems caused by multiple profiles entering the receiving trough simultaneously, significantly improving the stability and reliability of equipment operation. The lower feed plate, movable plate, and top feed plate form a stepped layout. Profiles in the stacking bin first fall onto the lower feed plate. Initially, the movable plate is level with the lower feed plate, and the profile rolls onto it. The movable plate, moving back and forth between the lower and top feed plates, lifts the profile, utilizing the side of the top feed plate as a sliding support surface. The movable plate and the side of the top feed plate form an angle to accommodate the profile, enhancing the stability of the feeding process. When the movable plate lifts the profile and passes over the top feed plate, the profile naturally adheres to that side and slides down under gravity. Since the movable plate only needs to support… The single profile is carried by its own weight, greatly reducing the torque and energy consumption required by the third drive component. This not only extends the service life of drive components (such as cylinders or motors) but also reduces the manufacturing cost and operating noise of the equipment. By constraining the movable plate to reciprocate within the narrow gap formed by the lower feed plate and the upper feed plate, a precise mechanical guide structure is essentially formed. When the movable plate is lifted and lowered by the third drive component, its lateral displacement is restricted by the side walls of the stack box, effectively preventing the movable plate from shaking or deflecting due to uneven force during the lifting process. This ensures that the profile on the movable plate can rise strictly along the preset vertical trajectory, avoiding the profile from swaying left and right during the lifting process. This greatly reduces the risk of jamming or getting stuck between the profile and surrounding components, and improves the smoothness of equipment operation.

[0014] This utility model further includes the following configuration: the feeding assembly includes a stepped feeding rack, which comprises a lower feeding plate, a lower feeding plate, and a top feeding plate arranged from bottom to top. The top feeding plate is located at the upper end of the slope. The lower feeding plate, the lower feeding plate, and the top feeding plate are all inclined downwards from the feeding end to the feeding end. A movable plate for sequentially feeding the profiles below into the upper plate is provided between the lower feeding plate, the lower feeding plate, and the top feeding plate. The upper surface of the movable plate is parallel to the slope of the lower feeding plate. The height of the movable plate is greater than the height of the lower feeding plate. The height difference between the movable plates is the same as the height difference between the lower feeding plate, the lower feeding plate, and the top feeding plate. The movable plates are connected by a connecting component. A third drive component is provided below the feeding rack to drive the movable plates to reciprocate up and down.

[0015] By adopting the above technical solution, traditional feeding mechanisms typically require lifting the profile vertically to a considerable height in one go to cross the material trough baffle. This places extremely high demands on the output torque and energy consumption of the drive components. This technical solution reduces the stroke height of a single feeding operation, decomposing the originally concentrated lifting action into multiple small-amplitude step-like lifts. Due to the shortened stroke, the gravitational potential energy that the third drive component needs to overcome is significantly reduced, thereby significantly reducing drive power and energy consumption. At the same time, the shorter the stroke of the actuator, the shorter the time required to complete a single action cycle. By reducing the stroke height of a single feeding operation, the lifting action of the movable plate becomes faster, greatly shortening the feeding cycle of a single profile and eliminating the constraint of the feeding link on the overall production line's cycle time, thereby significantly improving the overall production line's output per unit time.

[0016] The present invention further comprises: a feed inlet is provided at one end of the transition trough corresponding to the receiving trough; an adjustment limiting component for adjusting the size of the feed inlet is provided above the feed inlet; the adjustment limiting component includes a mounting base and a stop block for blocking the feed inlet; the stop block includes a connecting part that is detachably connected to the mounting base by fasteners and a stop part for blocking the upper end of the feed inlet; the mounting base is provided with an adjustment groove or multiple adjustment holes adapted to the fasteners.

[0017] By adopting the above technical solution and setting a mounting base with an adjustment groove or multiple adjustment holes, the installation position of the stop block can be flexibly adjusted along the height direction of the feed inlet. The operator can set the blocking height of the stop block according to the diameter of the profile being processed (generally less than twice the diameter), thereby changing the opening size of the feed inlet (when there is stacking in the receiving trough, the pushing component only pushes the lower profile into the transition trough, and the front end of the upper profile is blocked by the stop block. When the lower pushing component is reset, the upper profile falls to the bottom of the receiving trough), preventing two or more profiles from entering the straightening machine at the same time, resulting in high stability and wider applicability; the stop block is detachable and easy to install and adjust.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0026] See appendix Figure 1-5 A feeding mechanism for a double-headed bolt profile straightening device includes a stacking box 1, a receiving trough 2, a straightening mechanism 3, and a control component. The straightening mechanism 3 includes a straightening trough 31, straightening components 32 respectively disposed on the left and right sides of the straightening trough 31, and a first driving component 33 for driving the straightening components 32 to move left and right. The receiving trough 2 and the straightening trough 31 are connected by a transition trough 4. A pushing component 5 for pushing the profile in the receiving trough 2 forward is provided at the other end of the receiving trough 2 relative to the transition trough 4. The stacking box 1 is disposed on one side of the receiving trough 2. One end of the stacking box 1 corresponding to the receiving trough 2 is a feeding end 11. A ramp 12 is provided between the feeding end 11 and the receiving trough 2. The lower end of the ramp 12 is disposed above the receiving trough 2. The feeding end 11 is provided with a component for pushing the profile at the bottom of the stacking box 1 out of the stacking box 1. The feeding component 6 slides down the ramp 12 into the receiving trough 2. Above the receiving trough 2, there is a detection component 7 for monitoring the presence and height of the profiles in the trough. The detection component 7, the pushing component 5, the first drive component 33, and the feeding component 6 are electrically connected to the control component. (When the detection component 7 confirms that there are profiles in the receiving trough 2, the pushing component 5 pushes the profiles forward, causing the profiles in the transition trough 4 and the straightening trough 31 to move forward. The straightening trough 31 is then filled with unstraightened profiles. When the pushing component 5 resets, the control component controls the first drive component 33 to move the straightening component 32 in the closing direction to complete the straightening action and then separate. After the pushing component 5 resets, the detection component 7 confirms that the receiving trough 2 is empty. The control component controls the feeding component 6 to push the profiles at the bottom of the stacking box 1 out of the stacking box 1 so that they slide down the ramp 12 into the receiving trough 2. Then the above steps are repeated.)

[0027] In this utility model, the preferred driving method for the pushing component 5, the first driving component 33, and the feeding component 6 is a cylinder, but hydraulic cylinders, electric push rods, motor-driven gear push rod assemblies, worm gear mechanisms, or electric lead screws can also be used.

[0028] In this utility model's technical solution, the straightening assembly 32 includes a straightening wheel, a drive shaft, and a drive component that drives the straightening wheel to rotate via the drive shaft. Its connection structure and driving method are common existing designs and will not be described in detail. The difference between it and the existing straightening mechanism 3 is that the first drive component 33, which drives the straightening assembly 32 to move left and right, is electrically connected to the control component. Based on the signal from the detection component 7, after the material pushing component 5 has reset and confirmed that the new profile to be straightened is in place, the first drive component 33 will drive the straightening wheel to close. The control component thus achieves an interlocking mechanism between "feeding new material" and "starting straightening."

[0029] In this utility model technical solution, the bottom wall of the transition material groove 4 is provided with an inverted isosceles triangular groove, so that profiles of different diameters can be aligned in the center and are not easy to swing left and right during the pushing process. The bottom angle of the groove is preferably a large obtuse angle (close to 170 degrees is best); the straightening material groove 31 is provided with notches on both sides for the straightening wheel to move and close.

[0030] This embodiment further includes: a movable side plate 13 is provided inside the stacking box 1. The movable side plate 13 is connected to the fixed side of the stacking box 1 by adjusting bolts. The position of the movable side plate 13 can be adjusted by adjusting bolts to accommodate profiles of different lengths. An active space 131 for the feeding assembly 6 to move is provided between one end of the movable side plate 13 corresponding to the feeding end 11 and the feeding end 11 of the stacking box 1.

[0031] In this utility model, an adjusting bolt is used to adjust the distance between the movable side plate 13 and the side of the stacking box 1 to accommodate double-ended bolt profiles of different lengths. This adjusting bolt can be configured as a single-ended or double-ended threaded structure, with one or both ends threadedly connected to the movable side plate 13 and the fixed portion of the stacking box 1, respectively. By rotating the adjusting bolt, the movable side plate 13 moves laterally along the stacking box 1, thereby changing the effective accommodating width of the stacking box 1.

[0032] Preferably, an adjusting bolt assembly is provided between the movable side plate 13 and the side of the stacking box 1. This assembly includes at least one adjusting screw and a fixed nut seat threadedly engaged with it. One end of the adjusting screw is rotatably connected to the movable side plate 13, and the other end passes through a through hole in the side wall of the stacking box 1 and protrudes outwards. Rotating the adjusting screw drives the movable side plate 13 to move longitudinally. Furthermore, the adjusting screw can be equipped with scale markings or linked to a displacement sensor to achieve quantitative adjustment of the position of the movable side plate 13, thereby quickly adapting to profiles of known lengths. This screw adjustment method has a self-locking function, reliably maintaining the position of the movable side plate 13 after adjustment, preventing displacement due to vibration or thrust during profile loading, and ensuring loading accuracy.

[0033] This embodiment further includes: a rotating rod 14 above the ramp 12, and a limiting claw 15 on the rotating rod 14 to prevent the profile from falling directly into the receiving trough 2 along the ramp 12. The limiting claw 15 includes a connecting end 151 detachably connected to the rotating rod 14 and a limiting claw end 152 for limiting the profile. A second driving assembly 16 for driving the rotating rod 14 to rotate is provided on the outer periphery of the stacking box 1. The second driving assembly 16 is electrically connected to the control assembly. The second driving assembly 16 drives the limiting claw end 152 to abut or separate from the ramp 12 through the rotating rod 14.

[0034] In this utility model, the second drive assembly 16 includes a cylinder, a drive rod, and a connector. One end of the connector is snapped into the rotating rod 14, and the other end is hinged to the drive rod. The lower end of the cylinder is hinged to the stacking box 1.

[0035] This embodiment further includes the following configuration: the feeding assembly 6 includes a lower feeding plate 61 and a top feeding plate 62 arranged in a staggered manner. The top feeding plate 62 is located at the upper end of the ramp 12. A movable plate 63 is provided between the lower feeding plate 61 and the top feeding plate 62. The width of the movable plate 63 is adapted to the distance between the lower feeding plate 61 and the top feeding plate 62. The width of the movable plate 63 is less than twice the diameter of the profile. A third driving assembly 64 is provided below the movable plate 63 for driving the movable plate 63 to reciprocate up and down moving the material.

[0036] This embodiment further includes the following configuration: the feeding assembly 6 comprises a stepped feeding rack, which includes a lower feeding plate 61, a lower feeding plate 65, and a top feeding plate 62 arranged from bottom to top. The top feeding plate 62 is located at the upper end of the ramp 12. The lower feeding plate 61, the lower feeding plate 65, and the top feeding plate 62 are all inclined downwards from the feeding end to the feeding end 11. Useful facilities are provided between the lower feeding plate 61, the lower feeding plate 65, and the top feeding plate 62. The profiles below are sequentially fed into the upper movable plate 63. The upper end face of the movable plate 63 is parallel to the slope of the lower feeding plate 65. The height of the movable plate 63 is greater than the height of the lower feeding plate 65. The height difference between the movable plates 63 is the same as the height difference between the lower feeding plate 61, the lower feeding plate 65 and the upper feeding plate 62. The movable plates 63 are connected by connecting components. A third drive component 64 is provided below the feeding rack to drive the movable plates 63 to move up and down reciprocally.

[0037] See appendix Figure 4-5 In this utility model technical solution, a push rod is provided below the movable plate 63. The push rod is coupled with one of the following: a cylinder (hydraulic cylinder or electric push rod), a gear push rod assembly driven by a motor, or a worm gear mechanism, so as to realize reciprocating motion in the vertical direction. The number of stages of the lower loading plate 65 can be one or more, and its height difference matches the stroke of the push rod.

[0038] This embodiment further includes the following configuration: the transition material trough 4 is provided with a feed inlet 41 at one end corresponding to the receiving material trough 2, and an adjustment limiting component 8 for adjusting the size of the feed inlet 41 is provided above the feed inlet 41. The adjustment limiting component 8 includes a mounting base 81 and a stop block 82 for blocking the feed inlet 41. The stop block 82 includes a connecting part that is detachably connected to the mounting base 81 by a fastener and a stop part for blocking the upper end of the feed inlet 41. The mounting base 81 is provided with an adjustment groove or multiple adjustment holes adapted to the fastener.

[0039] In this utility model's technical solution, the position of the stop block 82 can be adjusted, preferably within 1.1 to 1.5 times the profile diameter, to limit the passage height of the feed inlet 41, allowing only a single profile to pass through. When the feeding component 6 accidentally lifts multiple stacked profiles, the topmost profile will be blocked by the height-limiting stop block 82, allowing only the bottommost profile to enter the transition trough 4. Furthermore, the detection component 7 can employ a laser sensor to detect the presence and stacking status of the profiles. The laser beam emitted by the sensor is aligned with the trough opening. When an abnormal height signal (indicating stacking) is detected, the control component can pause the operation of the feeding component 6 to prevent the feeding component 6 from pushing the profiles and causing further stacking.

[0040] The term "between" as used above does not only refer to directions or positions, but also to the interactions between different parts. Similarly, "up," "down," "left," "right," "front," and "back" are only relative positions used for ease of explanation and do not preclude the possibility of using other terms.

[0041] Although this document frequently uses terms such as: stacking bin 1, feeding end 11, ramp 12, movable side plate 13, movable space 131, rotating rod 14, limiting claw 15, connecting end 151, limiting claw end 152, second drive assembly 16, receiving trough 2, straightening mechanism 3, straightening trough 31, straightening assembly 32, first drive assembly 33, transition trough 4, feed inlet 41, pushing assembly 5, feeding assembly 6, lower feeding plate 61, upper feeding plate 62, movable plate 63, third drive assembly 64, lower feeding plate 65, detection assembly 7, adjusting and limiting assembly 8, mounting base 81, and stop block 82, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
