Description

Technical Field

[0001] The utility model belongs to the technical field of jigs and relates to a punch deformation correction jig. Background Art

[0002] In today's precision machining field, the application of micro punches is becoming increasingly widespread. However, due to inevitable material stress and machining process issues, all micro punches currently manufactured face some severe challenges.

[0003] First, the presence of material stress is a key factor. Various internal stresses are generated during the manufacturing and processing of materials. These stresses are more likely to cause deformation at the scale of a micro-punch. Furthermore, the limitations of the processing technology cannot be ignored. Despite continuous advancements in modern processing technology, it is still difficult to completely avoid various errors when processing micro-punches.

[0004] This deformation creates numerous problems for the use of punches. For one thing, deformation complicates punch assembly. In precision equipment, accurate punch assembly is crucial for proper function. However, deformation often increases the time and effort required for assembly, potentially leading to assembly failure and impacting production schedules. Furthermore, deformation shortens the punch's service life. Punches must withstand significant pressure and friction during operation, and a deformed punch's mechanical properties are affected, making it more susceptible to wear and breakage, significantly reducing its service life.

[0005] Currently, correction of micro-punch deformation is primarily performed manually. However, manual correction suffers from low precision. Differences in operator skill and experience lead to varying correction results, making it difficult to guarantee accurate punch correction. Furthermore, manual operation is inefficient and cannot meet the demands of large-scale production.

[0006] Therefore, there is an urgent need for a more efficient and accurate method for correcting deformation of micro punches to improve the quality and performance of the punches and meet the requirements of modern precision machining. Utility Model Content

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0038] See also Figure 1-Figure 3 As shown, a punch deformation correction jig includes a substrate 1, and a punch fixing device 2 is provided at one end of the substrate 1, whose function is to firmly fix one end of the punch 3 to ensure that the punch 3 does not loosen or move during the correction process. As the object to be corrected, the accuracy of the punch 3 directly affects the subsequent production and processing quality. A contact sensing device 4 is provided at the other end of the substrate 1, and the sensing head 41 on the contact sensing device 4 is arranged adjacent to the punch 3. When the punch 3 contacts the sensing head 41, the sensing head 41 can sensitively sense the punch 3 and provide accurate feedback information for the correction process.

[0039] On either side of the punch fixture 2 are screw assemblies 7 driven by reciprocating motors 6. Stainless steel scraping heads 8 are slidably mounted on these screw assemblies 7. These scraping heads 8 are made of high-quality steel, which offers high hardness and excellent wear resistance. The spacing between the scraping heads 8 matches the width of the punch 3, ensuring uniform correction across the entire width of the punch 3 during the correction process.

[0040] During the movement of the fine steel scraping heads 8 on both sides, the punch 3 is gradually corrected through the precise control of the reciprocating motor 6 and the screw assembly 7 until the induction head 41 contacts the punch 3. At this point, it indicates that the punch 3 has been corrected to the required state, the reciprocating motor 6 automatically stops, and the punch deformation correction is completed.

[0041] Furthermore, the contact sensing device 4 in this embodiment is equipped with two adjustment knobs 44, each of which is mounted with a sensing head 41. The use of the two adjustment knobs 44 allows the sensing head 41 to be flexibly adjusted to meet the correction requirements of punches 3 of different specifications. The two adjustment knobs 44 share a movable slide rail 43, making the overall structure more compact and stable.

[0042] Preferably, a numerical display is provided on the adjustment knob 44 to intuitively display the specific value of the adjustment, so that the operator can more accurately adjust the position of the sensor head. Scale lines are provided on the movable slide 43 to provide further reference for adjustment and ensure the accuracy and consistency of the adjustment.

[0043] The contact sensor 4 is equipped with an indicator light 42 that is linked to the sensor head 41. When the sensor head 41 senses the punch 3, the corresponding indicator light 42 illuminates, providing the operator with a clear signal. This design greatly improves the usability and reliability of the punch deformation correction jig. The operator can perform correction operations more efficiently and accurately through the combination of the numerical display, scale lines, and indicator lights.

[0044] In this embodiment, the induction head 41, the indicator light 42 and the reciprocating motor 6 are all electrically connected to the controller 9 on the workbench 5. This connection method ensures the precise control and efficient operation of the entire correction process. The induction head 41 senses the punch 3 and sends a signal to the controller 9. At the same time, the indicator light 42 will light up. The controller 9 can adjust the operation of the reciprocating motor 6 according to the received signal. The reciprocating motor 6 also drives the screw assembly accurately under the command of the controller, driving the fine steel grinding head to correct the punch. The entire punch deformation correction jig is powered by an external power supply unit, ensuring that it can operate stably and continuously.

[0045] In this embodiment, a front limiter 72 and a rear limiter 73 for limiting the movement range of the fine steel grinding and scraping head 8 are provided on the outer frame 71 of the screw assembly.

[0046] Integrating a conventional screw assembly into the outer frame 71 makes the entire structure more compact and stable. Linear guides on the outer frame 71 provide a track for the installation and movement of the front and rear stoppers 72 and 73. The front and rear stoppers 72 and 73 slide within the same linear guide 74 and can be locked to the linear guide 74 in a specific manner. This design allows the operator to flexibly adjust the position of the stoppers according to actual needs, thereby precisely controlling the range of movement of the fine steel grinding head.

[0047] Preferably, the front stopper 72 and the rear stopper 73 are both locking screws, and a locking block is provided below the linear guide groove 74, and the locking screw is threadedly connected to the locking block. On-site personnel can adjust the tightness between the locking screw and the locking block to achieve the movement or fixation of the locking screw on the linear guide groove 74.

[0048] The nut of the screw assembly is connected to the precision steel scraping head seat 75 through a slider, and the precision steel scraping head 8 is arranged on the precision steel scraping head seat 75. A linear slide is formed on the outer frame 71, and a slide groove matching the linear slide is provided on the precision steel scraping head seat 75. Driven by the reciprocating motor 6, the precision steel scraping head seat 75 moves smoothly along the linear slide. During the movement, the precision steel scraping head seat 75 can abut against the front limit member 72 or the rear limit member 73. When the precision steel scraping head seat abuts against the front limit member, it indicates that the precision steel scraping head has reached the front end of the moving range; when it abuts against the rear limit member, it indicates that it has reached the rear end of the moving range. This limit design ensures that the precision steel scraping head will not exceed the predetermined range during the process of correcting the punch, thereby ensuring the accuracy and safety of the correction.

[0049] The punch deformation correction jig of the present invention has significant advantages in practical applications. After the punch is fixed, the contact sensing device can be flexibly adjusted according to the specific size requirements to ensure that it can accurately sense the position changes of the punch. Then, the reciprocating motor starts, driving the fine steel scraping head to continuously scrape the punch. In this process, the fine steel scraping head can perform fine corrections on the deformed punch with its high hardness and good wear resistance. When the punch head contacts the induction head of the contact sensing device, the reciprocating motor stops automatically. This automated operation process greatly improves the accuracy and efficiency of the correction.

[0050] Compared to traditional manual correction methods, this new jig utilizes a mechanical structure, offering greater precision and efficiency. Manual correction is often subject to significant human influence, making dimensional stability difficult to ensure. This jig, however, corrects punch deformation to within 0.005 mm, achieving greater dimensional stability and reliability. Furthermore, its easy assembly and simple operation extend the punch's service life, reduce production costs, and significantly improve industrial production.
