Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, specifically relating to a cutting and punching device for workpieces. Background Technology

[0002] In existing workpiece machining processes, cutting and punching are two common machining operations that typically need to be completed on different machining equipment or stations. Because these two operations are independent, the same workpiece often needs to be clamped twice—first, the outer shape is cut on the cutting equipment, and then it is re-clamped on the punching equipment for hole machining. This step-by-step machining method inevitably introduces positioning errors and datum offsets during repeated clamping.

[0003] Each clamping operation relies on the operator's alignment accuracy or the fixture's repeatability. However, in practice, factors such as fixture wear, human error, and machine tool repeatability make it difficult to guarantee that the clamping position will be completely consistent each time. These errors accumulate gradually over multiple processes, eventually leading to dimensional deviations or out-of-tolerance geometric tolerances between the workpiece's cutting contour and punching position, severely affecting the product's assembly accuracy and overall quality. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, the technical problem to be solved by this utility model is as follows: A cutting and punching device for workpieces is proposed. By setting a first contour support block and a second contour support block to cover the workpiece's processing area, high-precision positioning and stable support of the workpiece are achieved. The cutting and punching processes can be completed continuously in a single clamping operation, avoiding the repeated positioning errors and cumulative errors of datum conversion caused by multiple clamping operations in traditional processes. This significantly improves the dimensional accuracy, geometric tolerance consistency, and relative positional accuracy between the cut and the hole.

[0016] In the above-mentioned cutting and punching device for workpieces, the movable base is further provided with:

[0017] A slider is slidably disposed on the movable seat and located to the side of the first contour support block. One end of the cutting part and the punching part are both disposed on the slider, and the other end extends toward the processing groove and the processing hole, respectively. The extension length of the cutting part is greater than that of the punching part. The slider is used to drive the cutting part and the punching part closer to or away from the workpiece.

[0019] In the above-mentioned cutting and punching device for workpieces, a collecting component is also provided on the operating table, which is located below the fixed block, for collecting cutting and punching waste.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) By setting the first and second contour support blocks to cover the workpiece to be processed area, the workpiece can be positioned with high precision and supported stably.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0044] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0045] like Figures 1 to 8 As shown, this solution provides a cutting and punching device for workpieces, comprising: an operating table 1; a first contouring support block 2 and a second contouring support block 3, respectively disposed on the operating table 1 and arranged opposite to each other, with the workpiece to be processed being covered between the first contouring support block 2 and the second contouring support block 3; a cutting component 4, one end of which is movably inserted through the first contouring support block 2 for cutting the workpiece; and a punching component 5, one end of which is movably inserted through the first contouring support block 2 and located to the side of the cutting component 4 for punching holes in the cut workpiece.

[0046] During operation, the workpiece to be processed is placed on the operating table 1, and the position of the workpiece to be processed is covered between the first contour support block 2 and the second contour support block 3. After the workpiece is in place, one end of the cutting part 4 passes through the first contour support block 2 along a preset path and cuts into the workpiece at a stable feed speed to complete the cutting operation. One end of the punching part 5 also passes through the first contour support block 2 along a preset path and moves towards the workpiece to perform punching processing on the cut workpiece.

[0047] Throughout the entire machining process, the first contouring support block 2 and the second contouring support block 3 consistently provide rigid support and positioning constraints for the workpiece. Especially under the significant cutting forces and impact loads generated during cutting and punching, they effectively suppress workpiece deformation, vibration, or displacement, ensuring machining stability. Since all processes are completed within a single clamping operation, the cumulative errors introduced by repeated positioning and datum conversion in traditional processes are avoided, significantly improving the dimensional accuracy, geometric tolerance consistency, and relative positional accuracy between holes and cuts. Furthermore, this integrated machining method greatly reduces process changeover time and the frequency of manual intervention, shortening the production cycle time and improving equipment utilization and overall production efficiency.

[0048] The cutting component 4 can be made of high-strength carbide tools or high-speed steel end mills, possessing excellent wear resistance and impact resistance, suitable for efficient cutting of various materials such as metals and plastics. The punching component 5, depending on the material thickness and hole diameter requirements, uses punches made of wear-resistant tool steel or high-speed steel, possessing good impact resistance and long service life.

[0049] In order to achieve stable support and positioning of the workpiece, the first contouring support block 2 is provided with a first contouring structure 6, and the second contouring support block 3 is provided with a second contouring structure 7. The first contouring structure 6 and the second contouring structure 7 together match the surface contour of the workpiece to be processed area. The first contouring support block 2 and the second contouring support block 3 respectively cover the workpiece to be processed area through the first contouring structure 6 and the second contouring structure 7, providing support and positioning for the workpiece.

[0050] Through the above structural design, the first contouring structure 6 and the second contouring structure 7 can achieve precise matching with the surface contour of the workpiece, effectively restricting the workpiece's degrees of freedom in multiple directions and preventing displacement or vibration during processing, thereby significantly improving positioning accuracy and processing stability. Simultaneously, the surface contact support method between the first contouring structure 6 and the second contouring structure 7 and the workpiece contour, compared to point contact or line contact, has a stronger load-bearing capacity and more uniform force distribution, reducing local stress concentration and preventing workpiece deformation or surface damage. Furthermore, this positioning method eliminates the need for frequent adjustments or replacements of fixture components, making it suitable for mass production, improving clamping efficiency and process repeatability, and helping to ensure consistent product processing quality.

[0051] To allow the cutting part 4 and the punching part 5 to pass through the first contouring support block 2 and process the workpiece to be processed between the first contouring support block 2 and the second contouring support block 3, the first contouring support block 2 is provided with a through processing groove 8 and a processing hole 9. The processing groove 8 is positioned corresponding to the workpiece to be cut, thus avoiding the cutting part 4; the processing hole 9 is positioned corresponding to the workpiece to be punched, thus accommodating the punching part 5. The cutting part 4 and the punching part 5 act on the workpiece through the processing groove 8 and the processing hole 9, respectively, to achieve cutting and punching processing. The inner diameters of the processing groove 8 and the processing hole 9 are matched with the outer diameters of the cutting part 4 and the punching part 5, respectively.

[0052] By setting through-type machining grooves 8 and machining holes 9 on the first contour support block 2 to match the cutting part 4 and the punched part 5, not only can the cutting part 4 and the punched part 5 pass smoothly, avoiding interference with the first contour support block 2, but the inner walls of the machining grooves 8 and machining holes 9 also provide guidance for the movement of the cutting part 4 and the punched part 5, effectively improving the straightness and positioning accuracy of the machining process. The dimensional matching design between the machining groove 8 and the cutting part 4, and between the machining hole 9 and the punched part 5, ensures smooth passage of the parts and reduces vibration and offset during the machining process, significantly improving the quality of the cut surface and the punched wall.

[0053] Meanwhile, the guiding function reduces reliance on additional guiding mechanisms, simplifies the equipment structure, and improves the stability and reliability of the overall process system. Furthermore, this integrated design combines support, positioning, and machining avoidance functions into the first contour support block 2, eliminating the need for additional auxiliary tooling. This helps shorten clamping time, improves production efficiency, and is particularly suitable for multi-stage continuous processing or automated production line scenarios, exhibiting good repeatability and process adaptability.

[0054] To prevent interference between the cutting component 4 and the punching component 5 and the second contouring support block 3, the second contouring support block 3 is provided with a first clearance groove 10 and a second clearance groove 11. The first clearance groove 10 is positioned opposite to the machining groove 8 on the first contouring support block 2, and the second clearance groove 11 is positioned opposite to the machining hole 9. One end of the cutting component 4 passes through the machining groove 8 and extends into the first clearance groove 10, and one end of the punching component 5 passes through the machining hole 9 and extends into the second clearance groove 11, forming a through machining channel.

[0055] This structural design allows the cutting component 4 and the punching component 5 to smoothly pass through the workpiece's processing position during the feed process, avoiding collisions or scratches with the second contour support block 3, thus ensuring the smoothness and safety of the processing path. With the workpiece stably positioned by the first contour support block 2 and the second contour support block 3, through-cutting or through-punching operations can be completed without the need for mid-process adjustment or disassembly of the support structure, improving processing continuity and efficiency.

[0056] The precise alignment between the machining groove 8 and the machining hole 9 with the first clearance groove 10 and the second clearance groove 11 not only ensures the straightness and coaxiality of the movement trajectory of the cutting part 4 and the punching part 5, but also plays an auxiliary guiding role on the exit side of the cutting part 4 and the punching part 5, effectively suppressing vibration and skew during the processing, reducing tool wear, and improving the punching position accuracy and cutting surface quality.

[0057] In addition, the through-type clearance channel design effectively combines the support function with the processing clearance function. While ensuring that the workpiece is supported by the first contouring structure 6 and the second contouring structure 7 throughout the process, it realizes the feasibility of multi-process composite processing and significantly enhances the process adaptability and reliability of the tooling system.

[0058] More preferably, the operating table 1 is also provided with: a fixed seat 12, on which a movable seat 13 and a fixed block 14 are provided, a first contour support block 2 is connected to the movable seat 13, and a second contour support block 3 is connected to the fixed block 14; a first driving member 15, the output end of which is connected to the movable seat 13, for driving the movable seat 13 to move.

[0059] More preferably, the movable base 13 is further provided with a slider 16, which is slidably disposed on the movable base 13 and located to the side of the first contour support block 2. One end of the cutting part 4 and the punching part 5 are both disposed on the slider 16, and the other end extends toward the machining groove 8 and the machining hole 9, respectively. The extension length of the cutting part 4 is greater than that of the punching part 5. The slider 16 is used to drive the cutting part 4 and the punching part 5 to move closer to or away from the workpiece. A second driving member 17 is provided, the output end of which is connected to the slider 16. The second driving member 17 is used to drive the slider 16 to slide on the movable base 13.

[0060] During operation, firstly, the first driving component 15 drives the moving seat 13 to position the first contouring support block 2 away from the second contouring support block 3. The workpiece is placed on the operating table 1, so that a portion of the structural contour of the workpiece's processing area is aligned with and abuts against the second contouring structure 7 on the second contouring support block 3, achieving initial positioning. Subsequently, the first driving component 15 is activated, moving the moving seat 13 and the first contouring support block 2 toward the workpiece until the first contouring structure 6 aligns with another portion of the structural contour of the workpiece's processing area, thus covering the workpiece's processing position together with the second contouring support block 3, completing the contouring positioning and stable support of the workpiece.

[0061] During the movement of the first contouring support block 2, the slider 16 mounted on its side moves synchronously with the moving seat 13, causing the cutting part 4 and the punching part 5 to move together to the corresponding position of the workpiece to be processed. After the workpiece is positioned, the second driving component 17 is activated, driving the slider 16 to move forward, causing the cutting part 4 and the punching part 5 to pass through the processing groove 8 and processing hole 9 on the first contouring support block 2 respectively, and feed towards the workpiece to be processed.

[0062] Because the extension length of the working end of the cutting part 4 is greater than that of the working end of the punching part 5, the cutting part 4 contacts and completes the cutting process of the workpiece first during the drive of the second drive 17. As the feed continues, the punching part 5 performs punching operations on the workpiece that has completed the cutting operation, realizing the sequential processing of cutting and punching. The second drive 17 independently controls the feed movement of the slider 16. Combined with the difference in the extension length of the cutting part 4 and the punching part 5 and the stroke control, the orderly execution of the cutting and punching processes is realized, avoiding processing interference and ensuring the accuracy of the process sequence.

[0063] Throughout the entire processing, the first contouring structure 6 and the second contouring structure 7 of the first contouring support block 2 and the second contouring support block 3 always maintain close contact with the surface contour of the workpiece. Even in processes that generate impact loads, such as cutting and punching, this structure can effectively disperse stress, suppress workpiece vibration and deformation, and prevent dimensional deviations or structural damage caused by localized stress.

[0064] In addition, the machining groove 8, the first clearance groove 10, the machining hole 9, and the second clearance groove 11 not only provide passageways for the cutting part 4 and the punching part 5, but also guide their movement paths, further improving the stability of the machining path and effectively ensuring the flatness of the cutting surface and the accuracy of the punching position.

[0065] This tooling system integrates contour positioning, support, machining avoidance, and tool feed functions into a single unit, featuring a compact structure and excellent motion coordination. Automatic clamping and positioning are achieved through the first drive component 15, while the second drive component 17 controls the machining sequence, reducing manual intervention and improving clamping consistency and process repeatability. It is particularly suitable for the mass production of irregularly shaped workpieces with complex contours and high precision requirements, exhibiting good versatility and scalability. The first drive component 15 and the second drive component 17 can be hydraulic cylinders, motors, or pneumatic cylinders.

[0066] In order to collect the cutting and punching waste, a collection component 18 is also provided on the operating table 1, which is located below the fixing block 14 and is used to collect the cutting and punching waste.

[0067] More preferably, the cutting and punching device in this solution further includes: a first guide trough 19, which is disposed on the second contour support block 3; a second guide trough 20, which is disposed on the fixed block 14; and a third guide trough 21, which is disposed through the fixed base 12. The first guide trough 19, the second guide trough 20, and the third guide trough 21 are connected in sequence, and the feed end of the first guide trough 19 is connected to the first clearance groove 10. The discharge end of the third guide trough 21 has a downwardly extending notch for allowing the cutting waste to flow to the collection member 18. A fourth guide trough 22 is disposed on the second contour support block 3; and a fifth guide trough 23 is inclinedly arranged on the fixed block 14. The fourth guide trough 22 and the fifth guide trough 23 are connected, and the feed end of the fourth guide trough 22 is connected to the second clearance groove 11. The discharge end of the fifth guide trough 23 is connected to the external environment for allowing the punching waste to flow out.

[0068] More preferably, the fixing block 14 is also provided with a stop block 24, which is arranged opposite to the discharge port of the fourth guide channel 22, and is used to guide the punching waste flowing out of the fourth guide channel 22 to the collection component 18.

[0069] During operation, the cut-off waste enters the first guide chute 19 from the first clearance chute 10, passes through the second guide chute 20 and the third guide chute 21, and falls into the collection unit 18 from the outlet of the third guide chute 21; the punching waste enters the fourth guide chute 22 from the second clearance chute 11, slides out along the inclined fifth guide chute 23, is guided by the stop block 24 and falls into the collection unit 18, thus realizing the orderly and centralized recycling of the two types of waste.

[0070] The first guide chute 19, the second guide chute 20, and the third guide chute 21 are connected in sequence to form a waste material guide channel. The fourth guide chute 22 and the fifth guide chute 23 are connected to form a punching waste material guide channel, and the punching waste material flowing out of the fifth guide chute 23 is guided by the baffle 24 into the collection unit 18. During the processing, the cut-off waste material and the punching waste material are guided to the collection unit 18 below through independent channels, which avoids the accumulation, scattering, or splashing of waste material inside the equipment, effectively improves the cleanliness of the work site, reduces the risk of operators being injured by stepping on or contacting sharp waste material, and improves production safety.

[0071] To ensure stable fixation of the workpiece, the operating table 1 is also equipped with: a support frame 25, with support frames 25 on both sides of the fixed base 12, the support frames 25 being used to provide support for the non-processing area of ​​the workpiece; a third driving component 26, which is mounted on the support frame 25, with a positioning rod 27 at the output end of the third driving component 26, and a through hole on the support frame 25, with one end of the positioning rod 27 passing through the through hole and pressing against the workpiece.

[0072] When the workpiece is placed on the operating table 1, its non-processing area is provided with auxiliary support by the support frames 25 on both sides, while the area to be processed is precisely placed on the contouring structure of the second contouring support block 3 to achieve primary positioning and support. Subsequently, the third driving component 26 is activated, driving the positioning rod 27 to pass through the through hole and press against the workpiece surface. The force applied by the rod is opposite in direction to the supporting force provided by the second contouring support block 3, forming a stable clamping force system, thereby achieving reliable fixation of the workpiece. The third driving component 26 can be a motor, hydraulic cylinder, or pneumatic cylinder.
