Description

Technical Field

[0001] This utility model relates to the field of tap processing technology, and in particular to a cutting device for tap processing. Background Technology

[0002] Taps, as a crucial tool for machining internal threads, are widely used in the machinery manufacturing industry. Their manufacturing process is complex, requiring a series of steps such as turning the outer diameter, quenching, and grinding to produce a high-precision, high-performance finished tap. These steps place extremely stringent requirements on the dimensional accuracy and surface quality of the tap, ensuring both efficient and high-quality tap machining.

[0003] In the tap production process, cutting the raw metal rod into small segments of equal size is the first step. Currently, the industry commonly uses sawing, which requires cutting the raw rod one segment at a time with a saw blade. This method is inefficient, time-consuming to cut a single segment, cannot meet the pace of large-scale production, and results in significant saw blade wear and high costs, seriously affecting the overall production efficiency and cost control of taps. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a cutting device for tap processing.

[0005] Technical solution: A cutting device for tap processing includes a table frame. An intermittent feeding mechanism, an end constraint mechanism, a cutting mechanism, and a limit switch are sequentially arranged at the upper end of the table frame along the conveying direction of the tap material. The intermittent feeding mechanism clamps and conveys the tap material forward. The end constraint mechanism fixes the front end of the tap material and cooperates with the cutting mechanism to perform the cutting operation. The limit switch is adjustablely mounted on the table frame to control the cutting length of the tap material. The front end of the tap material touches the limit switch during conveying and triggers it. A controller is also provided on the table frame, and the controller is electrically connected to the intermittent feeding mechanism, the cutting mechanism, and the limit switch.

[0006] Furthermore, it is particularly preferred that the intermittent material transfer mechanism includes a transfer cylinder, a linear guide pair, a platform, and a clamping cylinder. The linear guide pair is installed on the upper end of the table frame and is arranged parallel to the direction of the tap material transfer. The platform is installed on the movable end of the linear guide pair. The clamping cylinder is installed on the platform. A fixed clamping part is also installed on the platform. The fixed clamping part is arranged opposite to the telescopic end of the clamping cylinder. A proximity switch is installed on the fixed clamping part for sensing whether the tap material is clamped.

[0007] Furthermore, it is particularly preferred that the upper end of the table frame is provided with a long plate, which is arranged in a direction parallel to the material transport of the tap, and one end of the long plate passes between the telescopic end of the clamping cylinder and the platform and extends towards the end constraint mechanism.

[0008] Furthermore, it is particularly preferred that the end constraint mechanism includes two symmetrically arranged rectangular blocks, the center of which together form a circular horizontal through hole. One end of the horizontal through hole is an inlet, and the other end is an outlet. The tap material enters through the inlet of the horizontal through hole and exits through the outlet, and the inlet end is flared.

[0009] Furthermore, it is particularly preferred that an auxiliary constraint mechanism is provided between the end constraint mechanism and the intermittent material transfer mechanism. The constraint mechanism includes a fixed clamping plate and a movable clamping plate arranged opposite to each other. The fixed clamping plate is fixed to the upper end of the table frame, and the movable clamping plate is movably disposed at the upper end of the table frame via a longitudinal slide. The mechanism also includes a longitudinal telescopic cylinder that drives the movable clamping plate to move along the longitudinal slide. The longitudinal telescopic cylinder is disposed at the upper end of the table frame, and its telescopic rod is connected to the movable clamping plate.

[0010] Furthermore, it is particularly preferred that the cutting mechanism includes a hydraulic cylinder and a synchronizing cylinder. The hydraulic cylinder and the synchronizing cylinder are located near the outlet end of the horizontal through hole and are arranged opposite each other on both sides of the outlet. The hydraulic cylinder is mounted on the upper end of the table frame, and a cutter made of a rectangular alloy block is installed at the front end of the extension rod of the hydraulic cylinder. One side of the cutter is abutted against the side of the rectangular block with the outlet. A semi-circular notch is opened on the side of the cutter facing away from the hydraulic cylinder, and the position of the semi-circular notch corresponds to the position of the horizontal through hole. The synchronizing cylinder is mounted on the upper end of the table frame, and a cylindrical abutment is installed at the front end of the extension rod of the synchronizing cylinder. The extension rod of the synchronizing cylinder extends or retracts synchronously with the extension rod of the hydraulic cylinder.

[0011] Furthermore, it is particularly preferred that a material rack is provided on one side of the table frame, and a roller is provided at the upper end of the material rack, with the upper end of the roller being flush with the upper end of the long plate.

[0012] This utility model has the following advantages:

[0013] 1. This utility model utilizes an intermittent material transfer mechanism to achieve stable clamping and precise transmission of tap raw materials, and works in conjunction with an end constraint mechanism to effectively fix the front end of the tap raw materials, ensuring the stability of the cutting process. The cutting mechanism and the end constraint mechanism work together to quickly complete the cutting. The flexible installation and adjustment of the limit switch, combined with the precise control of the controller, can accurately control the cutting length and ensure the consistency of tap dimensions. This device significantly improves the efficiency of tap processing.

[0014] 2. The intermittent material transfer mechanism of this utility model is powered by a transfer cylinder, which precisely moves the platform along a linear guide pair to achieve stable and accurate transfer of the tap material. The cooperation between the clamping cylinder and the fixed clamping part utilizes the extension and retraction of the clamping cylinder to firmly clamp the tap material. A proximity switch can sense in real time whether the tap material is clamped in place, providing an accurate signal for subsequent cutting operations.

[0015] 3. The long plate of this utility model provides additional guidance and support for the transmission process of tap material, so that the tap material can maintain a more stable transmission path along the long plate before being transmitted to the end constraint mechanism.

[0016] 4. The inlet end of the circular horizontal through hole of the end constraint mechanism of this utility model adopts a trumpet-shaped design, which can more easily guide the tap material into the through hole. The end constraint mechanism can keep the front end of the tap material in the processing area to ensure the smooth progress of the cutting operation.

[0017] In addition, the fixed and movable clamping plates, together with the drive of the longitudinal telescopic cylinder, further clamp and fix the tap material before cutting, enhancing the stability of the cutting process and preventing the tap material from shifting or vibrating due to insecure clamping during the cutting process. Furthermore, the auxiliary constraint mechanism can also assist in clamping the tap material when the intermittent material transfer mechanism is running, preventing the clamped tap material from retracting synchronously when the intermittent material transfer mechanism retracts.

[0018] 5. This utility model utilizes a rectangular alloy block as the cutting blade of the hydraulic cylinder. A semi-circular notch on the side facing away from the hydraulic cylinder corresponds to the position of the horizontal through hole, enabling the cutting blade to precisely cut the tap material. The synchronous cylinder ensures synchronized movement of the cutting blade and the lower connector during the cutting process, resulting in smoother cutting action and preventing the cutting blade from shaking or tilting during cutting, thereby effectively improving cutting accuracy and quality.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0027] This embodiment provides a cutting device for tap processing, the structure of which is as follows: Figure 1-6 As shown, the device includes a table frame 1, on which an intermittent material conveying mechanism 2, an end constraint mechanism 3, a cutting mechanism 4, and a limit switch 5 are sequentially installed. A controller 6 is also mounted on the table frame 1. This device, designed for the cutting and processing of tap raw materials, achieves efficient, stable, and precise cutting operations, effectively solving the problems of low efficiency and poor stability in traditional sawing methods. It significantly improves tap production efficiency and processing quality, reduces production costs, and demonstrates remarkable practicality and innovation.

[0028] refer to Figure 1 and Figure 2The intermittent feeding mechanism 2 is a key component for achieving stable clamping and precise transmission of tap material. The intermittent feeding mechanism 2 includes a transmission cylinder 21, a linear guide pair 22, a platform 23, and a clamping cylinder 24. The transmission cylinder 21 is mounted on the upper end of the table frame 1, and its piston rod is connected to one side of the platform 23. The linear guide pair 22 is fixed on the upper end of the table frame 1 and is arranged along the transmission direction of the tap material. The platform 23 is mounted on the movable end of the linear guide pair 22 and can slide along the linear guide pair 22. The clamping cylinder 24 is mounted on the platform 23, and its telescopic end 241 faces the fixed clamping part 25. The fixed clamping part 25 is fixed on the platform 23 at a position opposite to the telescopic end of the clamping cylinder 24. The two cooperate to clamp the tap material. A proximity switch 26 is installed on the fixed clamping part 25 to sense whether the tap material is clamped in place.

[0029] The transmission cylinder 21 serves as the power source, driving the platform 23 to move forward intermittently along the linear guide pair 22. Specifically, when the platform 23 moves backward to the designated position, the extension end 241 of the clamping cylinder 24 actuates, cooperating with the fixed clamping part 25 to firmly clamp the tap material. At this time, the proximity switch 26 senses that the tap material has been clamped in place. Then, the transmission cylinder 21 drives the platform 23 to transmit forward along the linear guide pair 22. After reaching a predetermined distance, the clamping cylinder 24 cooperates with the fixed clamping part 25 to release the tap material. At this time, the proximity switch 26 sends an accurate signal for subsequent cutting operations. Simultaneously, the transmission cylinder 21 drives the platform 23 to move backward to the initial position again. By repeating the above actions, continuous intermittent transmission of the tap material can be achieved.

[0030] refer to Figure 1 and Figure 3 The end constraint mechanism 3 is used to constrain and fix the tip of the tap material during the cutting process, ensuring the stability and accuracy of the cutting. It consists of two symmetrically arranged rectangular blocks 31, with a circular horizontal through-hole 311 formed at the center of each block. One end of the horizontal through-hole 311 is an inlet 312, and the other end is an outlet 313. The inlet 312 is designed in a trumpet shape to facilitate the smooth entry of the tap material. The tap material enters through the inlet 312 of the horizontal through-hole 311, travels along the internal channel of the through-hole, and exits through the outlet 313. The trumpet-shaped inlet 312 more easily guides the tap material into the horizontal through-hole 311, ensuring smooth entry even if there is an angular deviation during transport. The end constraint mechanism 3 guides the tip of the tap material to the processing area, cooperating with the cutting mechanism 4 to perform the cutting operation, ensuring the stability of the tap material's tip position during the cutting process and improving the cutting accuracy and stability.

[0031] In addition, combined Figure 4An auxiliary constraint mechanism 8 is also provided, located between the end constraint mechanism 3 and the intermittent material transfer mechanism 2. This mechanism further enhances the clamping and fixing effect of the tap material before cutting. Specifically, it includes a fixed clamping plate 81 and a movable clamping plate 82 arranged opposite to each other. The fixed clamping plate 81 is fixed to the upper end of the table frame 1, while the movable clamping plate 82 is movably mounted on the upper end of the table frame 1 via a longitudinal slide table 83. A longitudinal telescopic cylinder 84 is installed on the upper end of the table frame 1, and its telescopic rod is connected to the movable clamping plate 82, driving the movable clamping plate 82 to move along the longitudinal slide table 83. When the tap material is transferred to this position via the intermittent material transfer mechanism 2, the telescopic rod of the longitudinal telescopic cylinder 84 actuates, pushing the movable clamping plate 82 towards the fixed clamping plate 81. The movable clamping plate 82 cooperates with the fixed clamping plate 81 to clamp the tap material from the side. When the intermittent feeding mechanism 2 pushes the tap material forward, the auxiliary constraint mechanism 8 provides a stable clamping effect on the tap material. When the platform 23 of the intermittent feeding mechanism 2 retracts backward, the clamping effect of the auxiliary constraint mechanism 8 prevents the tap material from being driven backward synchronously, ensuring the stability of the tap material during the cutting process, effectively preventing cutting errors caused by changes in the position of the tap material, and further improving the cutting quality.

[0032] refer to Figure 1 and Figure 5 The cutting mechanism 4 is specifically composed of a hydraulic cylinder 41 and a synchronous cylinder 42. The two are located near the outlet 313 of the horizontal through hole 311 and are arranged opposite each other on both sides of the outlet 313. The hydraulic cylinder 41 is installed on the upper end of the table frame 1. A cutter 43 made of a rectangular alloy block is installed at the front end of its telescopic rod. One side of the cutter 43 is in close contact with the side of the rectangular block 31 with the outlet 313. A semi-circular notch 431 is opened on the side of the cutter 43 facing away from the hydraulic cylinder 41. The position of the semi-circular notch 431 corresponds to the position of the horizontal through hole 311. The synchronous cylinder 42 is also installed on the upper end of the table frame 1. A cylindrical abutment 44 is installed at the front end of its telescopic rod. The telescopic rod of the synchronous cylinder 42 extends or retracts synchronously with the telescopic rod of the hydraulic cylinder 41. When the tap material is fixed by the end constraint mechanism 3 and clamped by the auxiliary constraint mechanism 8, the extension rod of the hydraulic cylinder 41 extends, driving the cutter 43 to move horizontally towards the tap material. At this time, the semi-circular notch 431 of the cutter 43 contacts the outer circumference of the tap material. Under the strong thrust of the hydraulic cylinder 41, the cutter 43 cuts into the tap material, achieving the cutting of the tap material. At the same time, the extension rod of the synchronous cylinder 42 extends synchronously, and the abutment joint 44 abuts against the rectangular block 31, providing stable support for the cutting action of the cutter 43, ensuring that the cutter 43 is subjected to uniform force during the cutting process, and avoiding the cutter 43 from shaking or tilting due to uneven force, thereby effectively improving the cutting accuracy and quality, and ensuring that the tap material can be cut quickly and accurately.

[0033] Limit switch 5 is adjustablely mounted on the table frame 1 via bolts and is used to control the cutting length of the tap. When the tip of the tap material touches limit switch 5 during transport, limit switch 5 is triggered. Controller 6, as the control center of the device, is mounted on the upper end of the table frame 1 and is electrically connected to the transmission cylinder 21 of the intermittent feeding mechanism 2, the hydraulic cylinder 41 of the cutting mechanism 4, and limit switch 5 via control circuits. By adjusting the position of limit switch 5 on the table frame 1, the cutting length of the tap material can be precisely set. When the tip of the tap material touches limit switch 5, limit switch 5 is triggered and transmits its signal to controller 6. Upon receiving this signal, controller 6 controls the transmission cylinder 21 of the intermittent feeding mechanism 2 to stop operating, and simultaneously controls the hydraulic cylinder 41 of the cutting mechanism 4 to perform the cutting operation, thereby achieving precise cutting of the tap material to the correct length. Controller 6 coordinates the actions of each component according to a preset program, ensuring the efficient and stable operation of the entire cutting device, realizing automated cutting of the tap material, and greatly improving production efficiency and processing accuracy.

[0034] In addition, the device is equipped with a long plate 7 and a material rack 9.

[0035] The long plate 7 is bolted to the upper end of the table frame 1, and its height is adjustable. The long plate 7 is arranged parallel to the direction of tap material transmission, with one end passing between the telescopic end 241 of the clamping cylinder 24 and the platform 23, and extending towards the end constraint mechanism 3. The presence of the long plate 7 provides additional guidance and support for the tap material transmission process, enabling the tap material to maintain a more stable transmission path along the long plate 7 before being transmitted to the end constraint mechanism 3.

[0036] The material rack 9 is located on one side of the table frame 1 and is used to place the raw material for taps to be processed. A roller is installed on the upper end of the material rack 9, and the upper end of the roller is flush with the upper end of the long plate 7. The raw material for taps is placed on the material rack 9, and under the action of the intermittent material conveying mechanism 2, the raw material for taps is rolled and conveyed to the processing area via the roller.

[0037] Workflow of tap raw material cutting and processing:

[0038] The first step, in actual work, is for the staff to place the tap material on the material rack 9.

[0039] In the second step, the transfer cylinder 21 of the intermittent material transfer mechanism 2 operates, pushing the platform 23 forward along the linear guide pair 22 to the designated position. At this time, the telescopic end 241 of the clamping cylinder 24 actuates, cooperating with the fixed clamping part 25 to clamp the tap material, and simultaneously the proximity switch 26 senses that the tap material is clamped in place. Subsequently, the tap material continues to be transferred forward under the drive of the platform 23, and the long plate 7 provides stable guidance and support for the tap material during the transfer process.

[0040] Third, when the tip of the tap material touches the limit switch 5, the limit switch 5 is triggered, and its signal is transmitted to the controller 6.

[0041] In the fourth step, after receiving the signal, the controller 6 stops the transmission cylinder 21, and the auxiliary constraint mechanism 8 assists in clamping the tap material. Simultaneously, the hydraulic cylinder 41 of the cutting mechanism 4 is activated. The extension rod of the hydraulic cylinder 41 extends, driving the cutter 43 to move towards the tap material. The semi-circular notch 431 of the cutter 43 contacts the tap material, achieving cutting. At the same time, the extension rod of the synchronization cylinder 42 extends synchronously, and the abutment joint 44 rests against the rectangular block 31, providing stable support for the cutter 43. After the material breaks off, it rolls down along the inclined guide plate 11 on the table frame 1 and is collected.

[0042] Fifth, after cutting is completed, the extension rods of hydraulic cylinder 41 and synchronous cylinder 42 retract. At this time, the transmission cylinder 21 of the intermittent material transfer mechanism 2 retracts and repeats the above actions.

[0043] This device, through the close cooperation of its components, achieves stable clamping, precise transmission, efficient cutting, and accurate length control of tap raw materials. It solves the problems of low efficiency and poor stability of traditional sawing methods, significantly improves the production efficiency and product quality of tap processing, and reduces production costs. It has good application prospects and promotion value.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention.
