Description

Technical Field

[0001] This invention relates to the field of thread rolling machine technology, specifically to a thread rolling machine with automatic loading and unloading. Background Technology

[0002] Thread rolling machines are high-efficiency cold extrusion forming equipment used for processing external threads, straight lines, knurling, and other processes. They are widely used in the processing of fasteners such as bolts and screws. In traditional thread rolling machine operation, the workpiece to be processed (such as a bolt) is usually manually placed into the machine's feed inlet, and then manually removed after the threads are rolled. This manual loading and unloading method is not only labor-intensive but also inefficient. Long-term repetitive work can easily lead to operator fatigue and poses certain safety hazards. Furthermore, the consistency of manual operation is poor, making it difficult to guarantee the stability of the processing quality for each batch of products.

[0003] Currently, while some thread rolling machines with automatic loading and unloading devices exist on the market, their structures are often complex, poorly compatible with existing thread rolling machine bodies, and costly to retrofit. Especially for small bolt-like workpieces, existing feeding mechanisms are prone to problems such as jamming, incomplete feeding, or difficulty in unloading, affecting the reliability of continuous equipment operation. Therefore, it is necessary to design a compact thread rolling machine that fits well with the main body of the thread rolling machine, enables automated loading and unloading, and operates stably, to solve the aforementioned problems in existing technologies. Summary of the Invention

[0004] 1. The technical problem that the invention aims to solve: This invention provides an automatic loading and unloading thread rolling machine to solve the technical problems existing in the background art.

Technical Solution: To achieve the above objectives, the technical solution provided by the present invention is: an automatic loading and unloading thread rolling machine, comprising a thread rolling machine body, wherein the thread rolling machine body has a processing station; A telescopic discharge mechanism is connected to the top of the thread rolling machine body via a detachable platform. The output end of the telescopic discharge mechanism is connected to an L-shaped discharge push plate, which is aligned with the processing station. The feeding mechanism, located in front of the processing station, includes a fixed base. The fixed base is detachably connected to the front side of the thread rolling machine body. A translation drive assembly is provided on the top of the fixed base, and a first sliding feeding table is reciprocated by the translation drive assembly. An L-shaped fixing block is connected to the end of the first sliding feeding table, and a concave feeding table is connected to the side of the L-shaped fixing block. A first push drive assembly is provided at the rear end of the concave feeding table, and the telescopic shaft of the first push drive assembly is aligned with the groove of the concave feeding table.

[0006] Furthermore, it also includes a feeding assembly, which includes a second drive assembly mounted on a support plate. The bottom of the support plate is detachably connected to the fixed base via a support column. The output end of the second drive assembly is connected to an L-shaped feeding plate. The L-shaped feeding plate has a feeding hole for accommodating bolts. When the L-shaped feeding plate extends, the bottom of the feeding hole is aligned with the groove of the concave feeding table.

[0007] Furthermore, guide rods are symmetrically arranged on the top of the thread rolling machine body, and the detachable platform is detachably connected to the guide rods through an arc-shaped connector; The telescopic discharge mechanism includes an L-shaped connecting block. The L-shaped connecting block is bolted to one side of the top of the detachable platform. A first telescopic cylinder is installed on the side of the L-shaped connecting block. The output shaft of the first telescopic cylinder is connected to an L-shaped mounting plate. The L-shaped discharge push plate is detachably connected to the side of the L-shaped mounting plate.

[0008] Furthermore, a discharge track is provided below the processing station to receive the workpiece pushed out by the L-shaped discharge pusher.

[0009] Furthermore, the translation drive assembly includes a sliding rail fixed to the top of the fixed base, and a second drive cylinder installed behind the sliding rail. The first sliding loading platform is slidably connected to the top of the sliding rail, and the telescopic end of the second drive cylinder is connected to the rear end of the first sliding loading platform.

[0010] Furthermore, the first push drive component adopts a third cylinder, the output shaft of the third cylinder is connected to the pusher, and the side of the third cylinder is detachably connected to the L-shaped fixing block through a connecting plate.

[0011] Furthermore, the top of the concave feeding platform is connected to an arc-shaped feeding track, and the top of the arc-shaped feeding track is connected to a vibratory feeder. The top of the bearing plate is also connected to an L-shaped support plate. The bottom of the L-shaped support plate has a clearance groove to facilitate the reciprocating sliding of the L-shaped feeding plate. The L-shaped support plate is connected to the arc-shaped feeding track by bolts.

[0012] Furthermore, a vertical guide plate is connected to the side of the L-shaped support plate, and a vertical unloading channel is formed between the vertical guide plate and the L-shaped support plate.

[0013] Furthermore, the arc-shaped connector is an arc-shaped clamp or an arc-shaped slider, and the arc-shaped connector is sleeved on the outside of the guide rod and bolted to the bottom of the detachable platform.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention features a rational design. Through the coordinated operation of the telescopic discharge mechanism, the feeding mechanism, and the feeding assembly, it achieves fully automated operation of the entire bolt process, from loading, feeding, and pushing to thread rolling and finished product output. This significantly reduces the intensity of manual operation and improves production efficiency. The combination design of the L-shaped feeding plate and the arc-shaped unloading track in the feeding assembly, combined with the size limitation of the feeding hole, enables quantitative feeding of bolts one by one, effectively avoiding the problems of jamming or overlapping feeding, and ensuring the stability and consistency of the feeding.

[0015] The snap-fit ​​structure between the arc-shaped connector and the guide rod in this application allows for flexible adjustment of the height of the detachable platform according to the thread rolling machine model or workpiece specifications, enhancing the equipment's versatility and adaptability. The inclusion of a clearance groove at the bottom of the L-shaped support plate and the vertical guide plate further optimizes the bolt feeding path, ensuring precise bolt placement into the feeding hole. The overall structure is compact and rationally laid out, resulting in low modification costs compared to existing thread rolling machines, making it suitable for batch bolt processing scenarios.

[0016] It should be noted that the structures not described in this invention are not related to the design points and improvement directions of this invention, and are the same as or can be implemented using existing technologies, so they will not be elaborated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] It should be noted that structures not described in this invention do not involve the design points and improvement directions of this invention, and can all be achieved using existing technologies known to those skilled in the art.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] See attached document Figure 1-8 This embodiment provides an automatic thread rolling machine, including a thread rolling machine body 1, a telescopic discharge mechanism 2, a feeding mechanism 4, and a feeding component 11.

[0026] The thread rolling machine body 1 has a processing station for accommodating bolts to be processed and performing thread rolling operations. The specific structure of the thread rolling machine body 1 can adopt existing horizontal or vertical thread rolling machines, which will not be described in detail here.

[0027] The telescopic discharge mechanism 2 is connected to the top of the thread rolling machine body 1 via a detachable platform 21. Specifically, guide rods 22 are symmetrically arranged on the top of the thread rolling machine body 1, and the bottom of the detachable platform 21 is detachably connected to the guide rods 22 via an arc-shaped connector 23. In this embodiment, the arc-shaped connector 23 is an arc-shaped clamp, which is sleeved on the outside of the guide rods 22 and engages with them. A bolt hole is provided at the top of the arc-shaped connector 23, and a through hole is provided at the corresponding position at the bottom of the detachable platform 21. The bolt passes through the through hole at the bottom of the detachable platform 21 and is screwed into the bolt hole at the top of the arc-shaped connector 23, thereby achieving a fixed connection between the detachable platform 21 and the guide rods 22.

[0028] The telescopic discharge mechanism 2 also includes an L-shaped connecting block 24, a first telescopic cylinder 25, an L-shaped mounting plate 26, and an L-shaped discharge pusher plate 3. The L-shaped connecting block 24 is bolted to one side of the top of the detachable platform 21, and the first telescopic cylinder 25 is mounted on the side of the L-shaped connecting block 24. The output shaft of the first telescopic cylinder 25 extends horizontally, and its end is connected to the L-shaped mounting plate 26. The L-shaped discharge pusher plate 3 is detachably bolted to the side of the L-shaped mounting plate 26, and its end is aligned with the processing station of the thread rolling machine body 1. When the thread rolling operation is completed, the first telescopic cylinder 25 is activated, its output shaft extends, and it drives the L-shaped mounting plate 26 and the L-shaped discharge pusher plate 3 to move towards the processing station, thereby pushing the processed bolt out of the processing station.

[0029] Below the processing station is a discharge track 17, which is used to receive the workpiece pushed out by the L-shaped discharge pusher 3. The discharge track 17 is inclined, with its inlet end located directly below the processing station and its outlet end extending to the outside of the thread rolling machine body 1, so as to guide the finished bolt into the collection container.

[0030] The feeding mechanism 4 is located in front of the processing station. The feeding mechanism 4 includes a fixed base 5, which is detachably connected to the front side of the thread rolling machine body 1 by bolts. The top of the fixed base 5 is provided with a translation drive assembly 6 and a first sliding feeding table 7 that is driven by the translation drive assembly 6 to move back and forth.

[0031] Specifically, the translation drive assembly 6 includes a sliding rail 61 fixed to the top of the fixed base 5 and a second drive cylinder 62 installed behind the sliding rail 61. The sliding rail 61 extends horizontally, pointing towards the processing station. A first sliding loading platform 7 is slidably connected to the top of the sliding rail 61, and the telescopic end of the second drive cylinder 62 is fixedly connected to the rear end of the first sliding loading platform 7. When the second drive cylinder 62 is activated, its telescopic end extends or retracts, thereby driving the first sliding loading platform 7 to reciprocate along the sliding rail 61 towards or away from the processing station.

[0032] The front end of the first sliding feeding table 7 is connected to an L-shaped fixing block 8, and the side of the L-shaped fixing block 8 is connected to a concave feeding table 9. The concave feeding table 9 has an overall U-shaped structure, and its interior has a groove for accommodating a single bolt. The rear end of the concave feeding table 9 is provided with a first pushing drive assembly 10. In this embodiment, the first pushing drive assembly 10 is a third cylinder 101. The cylinder body of the third cylinder 101 is detachably connected to the side of the L-shaped fixing block 8 through a connecting plate 103. The output shaft of the third cylinder 101 is connected to a pusher 102, and the output shaft and the pusher 102 are aligned with the groove of the concave feeding table 9. When the third cylinder 101 is started, its output shaft extends, driving the pusher 102 to move forward along the groove of the concave feeding table 9, thereby pushing the bolt located in the groove to the processing station of the thread rolling machine body 1.

[0033] The feeding assembly 11 is used to feed bolts to be processed one by one to the concave feeding table 9. The feeding assembly 11 includes a support plate 12, a support column 14, and a second drive assembly 13 mounted on the support plate 12. The support plate 12 is located on one side of the fixed base 5, and the bottom of the support plate 12 is detachably connected to the fixed base 5 through the support column 14. The second drive assembly 13 is mounted on the support plate 12. In this embodiment, the second drive assembly 13 is a fourth drive cylinder. The output shaft of the fourth drive cylinder is connected to an L-shaped feeding plate 15. The bottom of the L-shaped feeding plate 15 has a feeding hole 16 for accommodating bolts. The feeding hole 16 can accommodate horizontally placed bolts. When the fourth drive cylinder is started, its output shaft extends, driving the L-shaped feeding plate 15 to move forward, so that the bottom of the feeding hole 16 is aligned with the groove of the concave feeding table 9. At this time, the bolt in the feeding hole 16 falls into the groove of the concave feeding table 9 under the action of gravity, completing a single feeding.

[0034] To achieve continuous automated feeding, an arc-shaped unloading track 91 is connected to the top of the concave feeding table 9. The top of the arc-shaped unloading track 91 is used to connect a vibratory feeder, which uses existing technology and is not shown in the accompanying drawings. The vibratory feeder outputs the bolts to be processed to the arc-shaped unloading track 91 in a uniform posture, and the bolts slide downwards along the arc-shaped unloading track 91 under gravity. An L-shaped support plate 121 is also connected to the top of the support plate 12. The bottom of the L-shaped support plate 121 has a clearance groove, which provides clearance space for the reciprocating sliding of the L-shaped feeding plate 15, preventing motion interference. The top of the L-shaped support plate 121 and the bottom of the arc-shaped unloading track 91 are fixedly connected by bolts, thus forming a complete bolt unloading channel.

[0035] Furthermore, a vertical guide plate 122 is also connected to the side of the L-shaped support plate 121. A vertical feeding channel is formed between the vertical guide plate 122 and the L-shaped support plate 121, which is located directly above the feeding hole 16 of the L-shaped feeding plate 15. When the bolt slides from the arc-shaped feeding track 91 into the vertical feeding channel, the bolt falls vertically under the guidance of the vertical guide plate 122 and accurately falls into the feeding hole 16 of the L-shaped feeding plate 15, thereby ensuring the positional accuracy of each feeding.

[0036] In this embodiment, the automatic loading and unloading thread rolling machine operates by having a vibratory feeder sequentially output bolts to be processed. The bolts fall along the arc-shaped unloading track 91 and the vertical unloading channel into the feeding holes 16 of the L-shaped feeding plate 15. The fourth drive cylinder is activated, moving the L-shaped feeding plate 15 forward and feeding the bolts to the groove of the concave feeding table 9. The bolts fall into the groove under gravity. The fourth drive cylinder then resets. Next, the second drive cylinder 62 is activated, pushing the first sliding loading table 7 and the concave feeding table 9 towards the processing station. When the concave feeding table 9 reaches the predetermined position, the third cylinder 101 is activated, its output shaft extending to push the bolts in the groove into the processing station of the thread rolling machine body 1 via the pusher 102, and the thread rolling machine begins its thread rolling operation. After thread rolling is completed, the second drive cylinder 62 and the third cylinder 101 reset sequentially. Finally, the first telescopic cylinder 25 is activated, which drives the L-shaped discharge pusher 3 to push the processed bolts out of the processing station. The bolts fall into the discharge track 17 and slide out, completing one work cycle.

[0037] It should be noted that the air source and air supply pipeline required for the first telescopic cylinder 25, the second drive cylinder 62, the third cylinder 101, and the fourth drive cylinder in this application are not shown in the accompanying drawings. The air source can be a conventional air compressor or a centralized air supply system. The air supply pipeline includes main air pipes, branch air pipes, control valves, and connectors, etc. The specific structure, connection method, and control principle of the above-mentioned air source and pipeline are all conventional technical means in this field. Those skilled in the art can directly configure and install them according to actual working conditions, and will not be described in detail here.

[0038] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
