Description

Technical Field

[0001] This invention relates to the field of thread rolling machine technology, specifically to a high-efficiency thread rolling machine. Background Technology

[0002] In the manufacturing process of bolts, the workpiece is first die-cast into shape using a die-casting machine, and then the threads are rolled onto it. However, during the die-casting process, the workpiece is easily bent. If the bent workpiece is lost, it will increase production costs. Therefore, the workpiece needs to be straightened before rolling the threads onto the formed workpiece to proceed with subsequent operations.

[0003] Thread rolling machines are commonly used in bolt manufacturing. They are specialized devices for machining threads on screws. The process involves a moving thread rolling plate relative to a fixed thread rolling plate. Since both the moving and fixed plates have threads on their working surfaces, the moving plate slides relative to the fixed plate, and their working surfaces rub against each other. The threads press against the screw surface, thus rolling the threads. Thread rolling machines are lightweight, flexible, efficient, and offer advantages that other similar equipment cannot replace. They avoid the limitations of lathes, drilling machines, or manual tapping, saving time and labor, reducing the risk of thread damage, and minimizing tap breakage. Furthermore, thread rolling machines are suitable for all mechanical manufacturing industries, including machine tools, molds, machinery, plastic machinery, printing machinery, packaging machinery, construction machinery, automotive and motorcycle parts, aircraft engines, locomotives and rolling stock, tobacco machinery, and general machinery.

[0004] In the prior art, there is a Chinese patent with authorization announcement number CN223325391U entitled "A Buffer-Type High-Efficiency Thread Rolling Machine." This patent discloses a buffer-type high-efficiency bolt thread rolling machine, including a frame and a drive motor. The drive motor is located on one side of the frame, a mounting and moving assembly is mounted on the frame, the thread rolling roller is mounted on the frame, a buffer adjustment assembly is mounted on the frame, and slide rails are all located on the surface of the frame. A drive seat is slidably connected to the slide rails, and the output end of the drive seat is connected to the thread rolling roller. This technical solution solves the problem that existing thread rolling machines cannot straighten workpieces and lack buffering capabilities. Direct thread rolling can lead to incomplete thread rolling and product scrap.

[0005] For example, Chinese patent CN217529086U, entitled "An Automated Thread Rolling Machine," discloses an automated thread rolling machine, including a machine body and an automatic receiving device. A discharge belt is installed on the machine, extending into the automatic receiving device. The automatic receiving device includes a receiving box, a feeding rack, a brush mechanism, and a dust removal mechanism. The brush mechanism includes a power component and brushes; the power component drives the brushes to rotate and clean the receiving rack. The dust removal mechanism includes a compressed air tank, a pulse solenoid valve, and nozzles. The compressed air tank blows air from the nozzles through the pulse solenoid valve. In this patent, the power mechanism drives the brushes to rotate, thereby cleaning the parts on the feeding rack and removing debris. Simultaneously, the compressed air tank sprays pulsed airflow from the nozzles through the pulse solenoid valve to blow air from the nozzles, achieving automatic cleaning of debris without manual intervention, thus improving efficiency.

[0006] Existing technologies, including the aforementioned patents, can meet the requirements for bolt threading to a certain extent. However, during operation, a fixing mechanism is needed to secure the bolt before the thread rolling mechanism can be used to perform the thread rolling operation. In this process, after the fixing mechanism secures the bolt, it needs to be pushed to the position of the thread rolling mechanism before the subsequent thread rolling operation can be performed, resulting in a time lag and affecting work efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a high-efficiency wire rolling machine to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency thread rolling machine, comprising a base and a mounting frame mounted on the base, wherein a bearing frame is provided on the mounting frame and multiple workpieces are mounted in the bearing frame; a conveyor frame is slidably connected inside the base, and a power mechanism for driving the conveyor frame to slide is provided on the base, and a thread rolling assembly is also provided on the side of the base away from the mounting frame; side plates are provided on both sides of the base, and a clamping mechanism is provided between the conveyor frame and the side plates, wherein the clamping mechanism on the conveyor frame fixes the workpieces during the stroke in which the power mechanism drives the conveyor frame to slide toward the thread rolling assembly.

[0009] Furthermore, the clamping mechanism includes a clamping plate slidably connected inside the conveying frame, and an abutment rod is fixedly connected to the clamping plate. The abutment rod is connected to the side plate through a guide portion.

[0010] Furthermore, the guide portion includes a first guide groove, a second guide groove, and a third guide groove formed on the side plate, and the abutment rod slides sequentially within the first guide groove, the second guide groove, and the third guide groove.

[0012] Furthermore, the carrier frame is in a conductive shape, and a sealing element is provided at the bottom of the mounting frame. Multiple workpieces are installed in the carrier frame through the sealing element. The conveying frame and the sealing element are connected by a linkage. When the conveying frame slides to the bottom of the mounting frame, the linkage drives the sealing element to slide into the mounting frame, so that the workpiece at the bottom of the carrier frame falls into the conveying frame.

[0013] Furthermore, the sealing component includes a sealing plate slidably connected within the mounting frame, and multiple positioning springs are provided between the sealing plate and the mounting frame.

[0014] Furthermore, the linkage component includes a linkage rod fixedly connected to the conveying frame, and a linkage groove is provided at the bottom of the sealing plate. The linkage groove is inclined, and the linkage rod is slidably connected in the linkage groove.

[0015] Furthermore, the power mechanism includes a lead screw rotatably connected to the base, a screw sleeve fixedly connected to the bottom of the conveying frame, the screw sleeve being slidably connected to the base through a limiting groove, and the lead screw being threadedly connected to the screw sleeve. A servo motor for driving the lead screw to rotate is provided on the base, and the servo motor is connected to the lead screw.

[0016] Furthermore, the thread rolling assembly includes a support frame fixedly connected to the base, two thread rolling rollers rotatably connected to the support frame, the two thread rolling rollers being connected by a synchronization unit, and a drive motor for driving one of the thread rolling rollers to rotate is provided on the support frame.

[0017] Furthermore, the bottom of the base is provided with an anti-slip pad.

[0018] Compared with existing technologies, the advantages of this invention are as follows: This high-efficiency thread rolling machine, through the cooperation of the base, bearing frame, conveyor frame, power mechanism, thread rolling assembly, side plate, and clamping mechanism, achieves integrated operation of automatic workpiece feeding, clamping, and conveying during the stroke of the conveyor frame sliding towards the thread rolling assembly, effectively shortening the time interval from workpiece fixing to thread rolling and improving processing efficiency. Furthermore, during the sliding stroke of the conveyor frame, the clamping mechanism and the guide groove design on the side plate automatically complete the clamping and fixing of the workpiece as the conveyor frame moves towards the thread rolling assembly, resulting in a compact structure and reliable operation.

[0019] Furthermore, through the ingenious connection between the linkage and the sealing component, the bottom of the carrying frame is automatically opened during the sliding process of the conveyor frame, allowing the workpiece to fall accurately into the conveyor frame, avoiding manual intervention, improving the feeding accuracy and continuity, and resulting in better performance.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-12 The present invention provides a technical solution: a high-efficiency thread rolling machine, including a base 1 and a mounting frame 2 mounted on the base 1. A bearing frame 3 is provided on the mounting frame, and multiple workpieces 4 are installed in the bearing frame 3. A conveyor frame 5 is slidably connected inside the base 1, and a power mechanism 6 for driving the conveyor frame 5 to slide is provided on the base 1. A thread rolling assembly 11 is also provided on the side of the base 1 away from the mounting frame 2. Side plates 9 are provided on both sides of the base 1, and a clamping mechanism 10 is provided between the conveyor frame 5 and the side plate 9. During the stroke of the power mechanism 6 driving the conveyor frame 5 to slide towards the thread rolling assembly 11, the clamping mechanism 10 on the conveyor frame 5 fixes the workpieces 4.

[0036] Specifically, this high-efficiency thread rolling machine includes a base 1 and a mounting frame 2 mounted on the base 1. A support frame 3 is mounted on the mounting frame, and multiple workpieces 4 to be processed are installed within the support frame 3. A conveyor frame 5 is slidably connected inside the base 1, and a power mechanism 6 is provided on the base 1 to drive the conveyor frame 5 to slide. A thread rolling assembly 11 is also provided on the side of the base 1 away from the mounting frame 2. During use, the conveyor frame 5 transports the workpieces 4 to the thread rolling assembly 11 to complete the thread rolling operation. Side plates 9 are provided on both sides of the base 1, and a clamping mechanism 10 is provided between the conveyor frame 5 and the side plates 9. During the stroke of the power mechanism 6 driving the conveyor frame 5 to slide towards the thread rolling assembly 11, the clamping mechanism 10 on the conveyor frame 5 fixes the workpieces 4. Therefore, during use, the power mechanism 6 drives the conveyor frame 5 to slide on the base 1. When the conveyor frame 5 moves towards the thread rolling assembly 11, the clamping mechanism 10 automatically clamps and fixes the workpiece 4 in the carrier frame 3, ensuring that the workpiece 4 will not shift during the conveying process until it reaches the thread rolling assembly 11 for thread rolling. In this process, the automatic feeding, clamping and fixing and conveying of the workpiece 4 can be integrated, effectively shortening the time interval from fixing to thread rolling of the workpiece 4 and improving processing efficiency. Furthermore, during the sliding stroke of the conveyor frame 5, the clamping mechanism 10 and the guide groove design on the side plate 9 automatically complete the clamping and fixing of the workpiece 4 during the movement of the conveyor frame 5 towards the thread rolling assembly 11, without the need for additional power input, resulting in a compact structure and reliable operation.

[0037] In the embodiments provided by the present invention, the clamping mechanism 10 includes a clamping plate 101 slidably connected inside the conveying frame 5. An abutment rod 102 is fixedly connected to the clamping plate 101, and the abutment rod 102 is connected to the side plate 9 through a guide portion. Specifically, by cooperating with the guide portion on the side plate 9, when the conveying frame 5 moves, the guide portion guides the abutment rod 102 to drive the clamping plate 101 to move inward or outward, thereby clamping or releasing the workpiece 4. In this process, no additional power source is required, reducing the complexity of the equipment and the manufacturing cost. At the same time, the clamping action is synchronized with the conveying process.

[0038] In the embodiments provided by the present invention, the guide portion includes a first guide groove 104, a second guide groove 105, and a third guide groove 106 formed on the side plate 9. The abutment rod 102 slides sequentially within the first guide groove 104, the second guide groove 105, and the third guide groove 106. The shape and position of the different guide grooves control the movement trajectory of the clamping plate 101, enabling it to complete clamping or releasing actions at specific positions. In the initial state, the abutment rod 102 is in contact with the first guide groove 104, and the clamping plate 101 is only in contact with the workpiece 4. As the conveyor frame 5 slides on the base 1, the abutment rod 102 slides from the first guide groove 104 to the second guide groove 105. The second guide groove 105 is inclined so that the abutment rod 102 drives the clamping plate 101 to fix the workpiece 4. When the second guide groove 105 slides to the third guide groove 106, the abutment rod 102 and the clamping plate 101 have completed the fixation of the workpiece 4. When the conveyor frame 5 continues to slide, the abutment rod 102 will slide horizontally in the third guide groove 106 to meet the needs of the thread rolling operation.

[0039] In the embodiment provided by the present invention, a sliding groove is provided inside the conveying frame 5, the clamping plate 101 is slidably connected to the sliding groove, and a plurality of return springs 103 are provided between the clamping plate 101 and the sliding groove. The return springs 103 provide a reverse elastic force. When the abutment rod 102 is disengaged from the guide groove, the return springs 103 push the clamping plate 101 to reset and release the workpiece 4.

[0040] In the embodiments provided by this invention, the carrier frame 3 is conductive, and the bottom of the mounting frame 2 is provided with a sealing member 7. Multiple workpieces 4 are installed in the carrier frame 3 through the sealing member 7. The conveying frame 5 and the sealing member 7 are connected by a linkage 8. When the conveying frame 5 slides to the bottom of the mounting frame 2, the linkage 8 drives the sealing member 7 to slide inward into the mounting frame 2, so that the workpiece 4 at the bottom of the carrier frame 3 falls into the conveying frame 5. By driving the sealing member 7 to slide inward through the linkage 8, the workpiece 4 at the bottom of the carrier frame 3 automatically falls into the conveying frame 5, completing the automatic feeding. In this process, the automatic unloading and feeding of workpieces 4 are realized without manual intervention, improving feeding efficiency and continuity, while reducing errors and equipment downtime caused by human operation. It is suitable for continuous processing of a large number of workpieces 4.

[0041] In the embodiments provided by the present invention, the sealing component 7 includes a sealing plate 71 slidably connected in the mounting frame 2, and a plurality of positioning springs 72 are provided between the sealing plate 71 and the mounting frame 2. When the linkage component 8 is activated, the sealing plate 71 compresses the positioning springs 72 and opens the material drop port. After the workpiece 4 falls, the positioning springs 72 push the sealing plate 71 to reset, preventing the workpiece 4 from falling accidentally during non-material drop periods.

[0042] In the embodiments provided by the present invention, the linkage component 8 includes a linkage rod 81 fixedly connected to the conveying frame 5, and a linkage groove 82 is provided at the bottom of the sealing plate 71. The linkage groove 82 is inclined, and the linkage rod 81 is slidably connected in the linkage groove 82. The linkage rod 81 moves with the conveying frame 5 and slides in the inclined linkage groove 82 of the sealing plate 71, pushing the sealing plate 71 to move inward, opening the discharge port, and realizing the automatic discharge of the workpiece 4.

[0043] In the embodiments provided by this invention, the power mechanism 6 includes a lead screw 61 rotatably connected to the base 1, a threaded sleeve 62 fixedly connected to the bottom of the conveying frame 5, the threaded sleeve 62 being slidably connected to the base 1 via a limiting groove, and the lead screw 61 being threadedly connected to the threaded sleeve 62. A servo motor for driving the lead screw 61 to rotate is provided on the base 1, and the servo motor is connected to the lead screw 61. The servo motor drives the lead screw 61 to rotate, the threaded sleeve 62 moves on the lead screw 61, and drives the conveying frame 5 to slide on the base 1, realizing the automatic conveying of the workpiece 4. Furthermore, the lead screw 61 has high transmission accuracy and smooth operation, and can precisely control the position and moving speed of the conveying frame 5, improving the accuracy and reliability of the workpiece 4 conveying. At the same time, the servo motor is easy to control and adapts to the needs of different processing rhythms.

[0044] In the embodiments provided by this invention, the thread rolling assembly 11 includes a support frame fixedly connected to the base 1. Two thread rolling rollers 112 are rotatably connected to the support frame. The two thread rolling rollers 112 are connected by a synchronization unit 113, and a drive motor 111 for driving one of the thread rolling rollers 112 to rotate is provided on the support frame. The synchronization unit 113 is prior art and will not be described in detail here. The synchronous design of the two thread rolling rollers 112 improves the efficiency and consistency of thread rolling, avoids the problem of workpiece deformation or uneven threads caused by single-sided thread rolling, and at the same time, the synchronization unit 113 ensures the coordinated operation of the two rollers, improving the processing quality and equipment stability.

[0045] In the embodiments provided by this invention, an anti-slip pad is provided at the bottom of the base 1. The anti-slip pad improves the stability and safety of the equipment, reduces processing errors and equipment wear caused by vibration or displacement, and also reduces operating noise.

[0046] It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source, and this application is equipped with a control system for controlling the operation of the entire equipment.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
