Description

Technical Field

[0001] This invention relates to the field of stamping press technology, specifically to a stamping press bias adjustment device and its operation method. Background Technology

[0002] In the field of stamping technology, the precise matching of the die and the slide is the core prerequisite for ensuring the quality of stamped parts. Especially in mass production scenarios such as automotive parts and electronic components, where dimensional accuracy requirements are high, even a small bias error can lead to defects such as burrs, deformation or cracks in the parts.

[0003] Existing stamping machines typically guide and limit the slider using fixed guide rails. However, the assembly clearance of these fixed guide rails is difficult to adjust. During long-term use, the wear between the guide rail and the slider will further widen the clearance, causing the slider to easily deviate or tilt during the up and down stamping motion. This leads to a decrease in the parallelism between the mold and the slider, directly affecting the dimensional consistency of the stamped parts and making it difficult to meet the requirements of high-precision production.

[0004] Traditional stamping die positioning relies heavily on manual adjustments using tools such as levels and dial indicators. This requires highly experienced operators and is time-consuming. For example, a large stamping die weighing over 500 kg typically requires 2-3 workers to complete the hoisting, positioning, leveling, and fixing process, which can take 30-60 minutes, severely impacting production efficiency. Furthermore, manual calibration is susceptible to interference from operating techniques and environmental vibrations, making it difficult to guarantee the stability of die positioning accuracy. Subsequent production may still experience stamping quality problems due to minute die displacements.

[0005] Furthermore, existing stamping presses have poor adaptability. For molds of different specifications and thicknesses, it is often necessary to replace corresponding guide rail components, positioning fixtures, and other accessories to meet the requirements of mold installation and slide guiding. Accessory replacement not only increases equipment procurement costs and inventory pressure but also further prolongs mold changeover time. Especially in multi-variety, small-batch production models, frequent accessory replacements lead to frequent production interruptions and a significant reduction in equipment utilization. At the same time, replaced accessories require manual recalibration, further exacerbating the problems of unstable accuracy and low efficiency, making it difficult to adapt to the development trend of modern flexible manufacturing.

[0006] Therefore, a bias adjustment device and operation method for a stamping machine are proposed to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to provide a bias adjustment device and operation method for a stamping machine, so as to solve the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stamping press bias adjustment device and operating method, comprising a die plate, wherein columns are fixedly installed on the die plate along four axes, a mold is installed in the middle of the upper surface of the die plate, a guide post is fixedly installed on the die plate near the outer side of the mold, a crossbeam is fixedly installed at the upper end of the guide post, the upper end of the column is fixedly installed on the crossbeam, and a slider is slidably installed on the outer surface of the guide post; the stamping press bias adjustment device further comprises a positioning adjustment mechanism and a horizontal mechanism. The positioning adjustment mechanism is installed on the column and the slider, and the positioning adjustment mechanism is used for the stamping adjustment of the slider; The horizontal mechanism is located below the grinding wheel and is used for the auxiliary installation of the grinding wheel.

[0009] Preferably, the positioning adjustment mechanism includes an adjustment slide rail, the upper end of which is slidably mounted on the crossbeam. The adjustment slide rails are symmetrically arranged, and a connecting groove is provided in the middle of the adjustment slide rail. Limiting blocks are symmetrically slidably mounted on both ends of the slider, and the end of the limiting block away from the slider is slidably mounted in the connecting groove of the adjustment slide rail.

[0010] Preferably, a fixing block is fixedly installed in the middle of the adjusting slide rail, a bidirectional threaded rod is threadedly installed in the middle of the fixing block, a fixing ring is fixedly connected in the middle of the bidirectional threaded rod, the two ends of the bidirectional threaded rod have threaded grooves in opposite directions, the two ends of the bidirectional threaded rod are rotatably mounted on the column, and a pressing column is fixedly connected in the middle of the lower surface of the adjusting slide rail.

[0011] Preferably, an L-shaped positioning plate is provided below the adjusting slide rail, and an extrusion groove is provided in the middle of the L-shaped positioning plate. The extrusion column is slidably installed in the extrusion groove, and the bottom of the L-shaped positioning plate is slidably installed on the crossbeam. The adjusting slide rail is symmetrically arranged at both ends of the mold, and the L-shaped positioning plate is used for self-positioning adjustment of the mold.

[0012] Preferably, the horizontal mechanism further includes beveled positioning posts, which are symmetrically fixedly installed on the lower surface of the mold. The lower surface of the beveled positioning posts is provided with an inclined surface, and a trapezoidal slide is provided on the inclined surface of the lower surface of the beveled positioning posts. The trapezoidal slide is slidably installed in the pressing mold table. An adjustment groove is opened in the middle of the trapezoidal slide, and an auxiliary pressure plate is installed in the adjustment groove of the trapezoidal slide. The auxiliary pressure plate is rotatably installed in the middle of the pressing mold table, and the trapezoidal slides are symmetrically arranged in the pressing mold table.

[0013] Compared with the prior art, the bias adjustment device and operating method for a stamping machine provided by the present invention have the following beneficial effects: I. Improve the precision of slide block stamping to ensure the stability of stamped parts quality; In existing technologies, stamping presses mostly rely on fixed guide rails to guide the slider. The assembly clearance of these fixed guide rails cannot be adjusted, and wear after prolonged use widens the clearance, causing the slider to easily deviate or tilt during vertical movement. This disrupts the parallelism between the mold and the slider, leading to quality problems such as burrs and deformation in the stamped parts. This solution utilizes a symmetrical adjusting slide rail and a bidirectional threaded rod in a positioning adjustment mechanism. The rotating bidirectional threaded rod moves the adjusting slide rail synchronously closer to or further away, dynamically eliminating the assembly and wear clearances between the adjusting slide rail and the slider. Simultaneously, the connection groove between the limiting block and the adjusting slide rail balances the forces and guiding forces on both sides of the slider, ensuring that the slider always moves along a precise trajectory. This effectively avoids bias errors, significantly improves the dimensional accuracy and consistency of the stamped parts, and reduces quality defects at their source.

[0014] Second, it enables mold self-positioning and adjustment, reducing reliance on manual labor and calibration time; Traditional stamping die installation requires manual adjustment using tools such as levels and dial indicators. This not only demands high operator experience but also involves a tedious and time-consuming calibration process, and is susceptible to interference from environmental vibrations, resulting in poor positioning accuracy and stability. This solution addresses this by linking the extrusion column of the positioning adjustment mechanism with the L-shaped positioning plate. As the adjustment slide rail moves, the extrusion column slides along the extrusion groove of the L-shaped positioning plate, automatically limiting the horizontal position of the die. Simultaneously, the angled positioning column of the horizontal mechanism contacts the trapezoidal slide via an inclined surface, achieving initial pre-positioning under the die's own weight. The auxiliary plate also provides reverse support to correct minor displacements. This entire structure achieves self-positioning adjustment of the die, eliminating the need for repeated manual calibration, significantly reducing die installation time, decreasing reliance on operator experience, and providing more stable positioning accuracy.

[0015] Third, enhance the adaptability of the equipment and reduce the cost of replacing parts and changing molds; Existing stamping machines suffer from poor adaptability. For molds of different specifications and thicknesses, corresponding guide rail assemblies, positioning fixtures, and other accessories need to be replaced, increasing equipment procurement and inventory costs, and extending mold changeover time. This is especially problematic in multi-variety, small-batch production, where frequent accessory changes lead to production interruptions and low equipment utilization. This solution eliminates the need to replace core components. By simply adjusting the slide rail spacing by rotating the bidirectional threaded rod, it can accommodate slides and molds of different widths. Simultaneously, the self-positioning adjustment of the L-shaped positioning plate and the inclined surface adaptation structure of the horizontal mechanism can simultaneously adapt to the installation requirements of molds of different sizes. This improved adaptability reduces the frequency of customizing and replacing specialized accessories, shortens mold changeover cycles, lowers equipment operating costs, and better meets the needs of flexible production.

[0016] IV. Dynamically correct mold horizontal deviations to extend the service life of equipment and molds; Existing technologies struggle to address mold tilting issues caused by installation errors, die deformation, or long-term wear. Mold tilt leads to uneven force distribution during stamping, affecting product quality and generating additional lateral forces. This exacerbates abnormal wear on critical components such as equipment guides and mold cutting edges, shortening their lifespan. This solution's horizontal mechanism can monitor mold status in real time. When a slight tilt occurs, the angled positioning pin and the inclined surface of the trapezoidal slide generate a lateral adjustment force. The auxiliary pressure plate further corrects the mold position through leverage, dynamically eliminating horizontal deviations and ensuring the mold and slide remain precisely parallel, preventing additional lateral forces. This not only guarantees production stability but also reduces wear on critical components, significantly extending the lifespan of equipment and molds, and lowering maintenance and replacement costs.

[0019] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] For an example, please refer to... Figures 1 to 7 As shown: To address the problems mentioned in the technical solutions, this application provides a stamping press bias adjustment device and operating method, including a die table 1, a column 12 fixedly mounted on the die table 1 with four axes, a mold 14 mounted on the middle of the upper surface of the die table 1, a guide post 13 fixedly mounted on the outside of the die table 1 near the mold 14, a crossbeam 11 fixedly mounted on the upper end of the guide post 13, the upper end of the column 12 fixedly mounted on the crossbeam 11, and a slider 15 slidably mounted on the outer surface of the guide post 13. The stamping press bias adjustment device also includes a positioning adjustment mechanism 2 and a horizontal mechanism 3. The positioning adjustment mechanism 2 is installed on the column 12 and the slider 15. The positioning adjustment mechanism 2 is used for the stamping adjustment of the slider 15. The horizontal mechanism 3 is located below the mold 14 and is used for the auxiliary installation of the mold 14. Specifically, such as Figure 4 As shown, the upper end of the adjusting slide rail 21 is slidably mounted on the crossbeam 11. The adjusting slide rail 21 is symmetrically arranged, and a connecting groove is opened in the middle of the adjusting slide rail 21. Limiting blocks 22 are symmetrically slidably mounted on both ends of the slider 15. The end of the limiting block 22 away from the slider 15 is slidably mounted in the connecting groove opened in the adjusting slide rail 21. A fixing block 23 is fixedly mounted in the middle of the adjusting slide rail 21. A double-threaded rod 24 is threadedly mounted in the middle of the fixing block 23. A fixing ring 25 is fixedly connected in the middle of the double-threaded rod 24. The two ends of the double-threaded rod 24 have threaded grooves with opposite directions. The two ends of the double-threaded rod 24 are rotatably mounted on the column 12. A pressing column 28 is fixedly connected in the middle of the lower surface of the adjusting slide rail 21. This scheme adopts a symmetrical structure of adjusting slide rail 21 to balance the force and guiding force on both sides of the slider 15, avoid the slider 15 from deviating, tilting or jamming during the up and down movement, and ensure the straightness of the stamping action. Simultaneously, rotating the bidirectional threaded rod 24 can cause the adjusting slide rail 21 to move closer or further away synchronously. By setting an adjustable spacing between the adjusting slide rail 21, the assembly gap or wear gap between the adjusting slide rail 21 and the slider 15 can be eliminated, reducing vibration and displacement during the stamping process and directly improving the dimensional accuracy and consistency of the stamped parts. Furthermore, for stamping dies of different thicknesses and specifications, there is no need to replace the entire adjusting slide rail 21 assembly; simply adjusting the spacing of the limiting adjusting slide rail 21 can accommodate sliders 15 of different widths or die installation requirements. This improved adaptability reduces the frequency of customizing and replacing dedicated adjusting slide rails 21, shortening production die changeover time, making it particularly suitable for multi-variety, small-batch stamping production scenarios.

[0022] Further as Figure 5As shown, an L-shaped positioning plate 26 is provided below the adjusting slide rail 21. An extrusion groove 27 is provided in the middle of the L-shaped positioning plate 26. An extrusion column 28 is slidably installed in the extrusion groove 27. The bottom of the L-shaped positioning plate 26 is slidably installed on the crossbeam 11. The adjusting slide rail 21 is symmetrically arranged at both ends of the mold 14. The L-shaped positioning plate 26 is used for self-positioning adjustment of the mold 14. By adjusting the slide rail 21, the bottom of the mold 14 can be synchronously limited. By sliding the extrusion column 28, the L-shaped positioning plate 26 can be driven to extrude the mold 14, thereby limiting and adjusting the mold 14 during installation, increasing the structural linkage and simultaneously adapting to the adjustment when installing different molds 14.

[0023] Specifically, the angled positioning posts 31 are symmetrically fixedly installed on the lower surface of the mold 14. An inclined surface is provided on the lower surface of the angled positioning posts 31, and a trapezoidal slide 32 is provided on the inclined surface of the lower surface of the angled positioning posts 31. The trapezoidal slide 32 is slidably installed in the pressing platform 1. An adjustment groove is provided in the middle of the trapezoidal slide 32, and an auxiliary pressure plate 34 is installed in the adjustment groove of the trapezoidal slide 32. The auxiliary pressure plate 34 is rotatably installed in the middle of the pressing platform 1. The trapezoidal slides 32 are symmetrically arranged in the pressing platform 1. A horizontal mechanism 3 is provided below the mold 14, which can detect and dynamically adjust the mold in real time. The positive abrasive 14 prevents tilting caused by installation errors, table deformation, or long-term wear, ensuring that the mold and stamping slide 15 always remain precisely parallel. This effectively avoids defects such as burrs and deformation of parts caused by uneven force during stamping, improving product accuracy and consistency. At the same time, it can eliminate additional lateral forces, reduce abnormal wear of key components such as equipment guide rails and mold cutting edges, and extend their service life. In addition, it can replace repeated manual adjustments, shorten mold change time, reduce reliance on operating experience, and significantly improve efficiency while ensuring production stability.

[0024] Example 2 addresses the problem in the prior art where insufficient equipment adjustment precision often results in excessive edge burrs and localized dents and deformations in the processed reinforcing plates. Therefore, this solution is specifically applied as follows, and the specific implementation process is as follows: Step 1: Device installation and initial commissioning; Basic component assembly: Fix the die plate 1 at the center of the press worktable, ensuring that the horizontal error of the table surface is ≤0.05mm; then weld and fix the columns 12 at the four-axis position of the die plate 1. The top of the column 12 is connected to the crossbeam 11 by high-strength bolts, ensuring that the parallelism between the lower surface of the crossbeam 11 and the upper surface of the die plate 1 is ≤0.03mm; on the upper surface of the die plate 1 near the outside of the mold installation area, install 4 guide posts 13 symmetrically. The vertical accuracy of the guide posts 13 and the die plate 1 is ≤0.02mm, and the upper end is fixed to the crossbeam 11 to form a stable frame structure.

[0025] Installation of Positioning Adjustment Mechanism 2: Two sets of adjusting slide rails 21 are symmetrically slidably installed on the lower surface of the crossbeam 11. A connecting groove with a width matching the limiting block 22 is opened in the middle of the adjusting slide rail 21. Limiting blocks 22 are symmetrically fixed at both ends of the slider 15 and embedded in the connecting groove of the adjusting slide rail 21 to ensure that the slider 15 slides up and down along the guide post 13 without jamming. A fixing block 23 is welded in the middle of the adjusting slide rail 21. A bidirectional threaded rod 24 passes through the fixing block 23 and is rotatably connected to the column 12. A fixing ring 25 is welded in the middle of the bidirectional threaded rod 24, and the threaded grooves at both ends are opposite in direction to facilitate subsequent synchronous adjustment. An extrusion column 28 is welded in the middle of the lower surface of the adjusting slide rail 21. At the same time, an L-shaped positioning pressure plate 26 is slidably installed on the lower surface of the crossbeam 11. An extrusion groove 27 matching the extrusion column 28 is opened in the middle of the L-shaped positioning pressure plate 26. The extrusion column 28 is embedded in the extrusion groove 27 to complete the linkage assembly of the positioning adjustment mechanism 2.

[0026] Horizontal mechanism 3 installation: Four angled positioning posts 31 are symmetrically welded on the lower surface of the mold 14, and the lower surface of the angled positioning posts 31 is machined with a 30° slope; a sliding groove is opened at the corresponding position on the upper surface of the pressing table 1, and four trapezoidal slides 32 are slidably installed in the sliding groove, and the upper surface of the trapezoidal slides 32 is machined with a slope that matches the angled positioning posts 31; an adjustment groove is opened in the middle of the trapezoidal slides 32, and the middle part of the auxiliary pressure plate 34 is rotatably installed in the pressing table 1 through a rotating shaft, and the two ends of the auxiliary pressure plate 34 are embedded in the adjustment groove of the trapezoidal slides 32, so as to realize the linkage and adaptation between the horizontal mechanism 3 and the mold 14.

[0027] Step 1: Mold installation and bias adjustment; Preliminary mold positioning: The aluminum alloy car door reinforcement plate special mold 14 is hoisted to the center of the upper surface of the pressing table 1. At this time, the angled positioning post 31 on the lower surface of the mold 14 contacts the inclined surface of the upper surface of the trapezoidal slide 32. Under the action of the mold's own weight, the angled positioning post 31 presses the trapezoidal slide 32, causing the trapezoidal slide 32 to slide outward along the sliding groove of the pressing table 1. When the trapezoidal slide 32 slides, its adjustment groove pushes the auxiliary pressure plate 34 to rotate around the pivot. The auxiliary pressure plate 34 generates a reverse support force on the trapezoidal slide 32, initially restricting the horizontal displacement of the mold 14 and completing the pre-positioning of the mold.

[0028] Slider 15 stamping accuracy adjustment: According to the stamping stroke requirements of mold 14, the operator uses a wrench to rotate the fixing ring 25 in the middle of the bidirectional threaded rod 24. Since the thread grooves at both ends of the bidirectional threaded rod 24 are in opposite directions and are threadedly connected to the fixing block 23 of the adjusting slide rail 21, during the rotation, the two sets of adjusting slide rails 21 move closer or further away from each other along the crossbeam 11. The parallelism between slider 15 and the upper surface of mold 14 is detected in real time by dial indicator. When the parallelism error is ≤0.01mm, the bidirectional threaded rod 24 is stopped from rotating. At this time, the adjusting slide rail 21 restricts the sliding direction of slider 15 through the limit block 22 to ensure that slider 15 always maintains precise parallelism with mold 14 during stamping and eliminates bias error.

[0029] Mold self-positioning calibration: During the synchronous movement of the adjusting slide rail 21, the extrusion column 28 on its lower surface slides along the extrusion groove 27 of the L-shaped positioning plate 26. Since the extrusion groove 27 is an inclined structure, the extrusion column 28 pushes the L-shaped positioning plate 26 to move along the crossbeam 11 toward the mold 14 when it slides. When the inner side of the L-shaped positioning plate 26 is in close contact with the outer wall of the mold 14, the adjustment stops. At this time, the L-shaped positioning plate 26 performs secondary positioning of the mold 14 from the horizontal direction. Combined with the vertical support of the horizontal mechanism 3, the mold 14 achieves all-round self-positioning calibration with a calibration error ≤0.02mm.

[0030] Step 1: Batch production and dynamic adaptation; Mass production operation: Start the stamping machine, and the slider 15 moves down at a constant speed along the guide direction of the guide post 13 and the adjusting slide rail 21 to stamp the aluminum alloy sheet on the die table 1; During the production process, the trapezoidal slide table 32 and the auxiliary pressure plate 34 of the horizontal mechanism 3 sense the slight displacement of the die 14 in real time, and dynamically correct the horizontal deviation of the die 14 through inclined contact and lever action to ensure the uniformity of force for each stamping; The adjusting slide rail 21 and the limiting block 22 of the positioning adjustment mechanism 2 continuously limit the offset of the slider 15 to avoid the impact of the guide clearance caused by long-term operation on the stamping accuracy.

[0031] Multi-specification mold replacement: When it is necessary to replace another aluminum alloy window frame mold with a thickness of 1.5mm, simply rotate the bidirectional threaded rod 24 in the opposite direction to make the adjusting slide rail 21 move away synchronously. The L-shaped positioning pressure plate 26 is removed from the original mold under the reset action of the extrusion groove 27. After hoisting the new mold to the pressing table 1, repeat the above "mold installation and bias adjustment" steps. The entire mold replacement process can be completed by one technician in 15 minutes, and the positioning accuracy of the new mold can still be maintained at ≤0.02mm.

[0032] In this embodiment, the bias adjustment device for the stamping machine has significant advantages over the prior art: First, by synchronously adjusting the bidirectional threaded rod 24 of the positioning adjustment mechanism 2 and linking and limiting the L-shaped positioning pressure plate 26, the problem of low precision and reliance on manual calibration for mold positioning in the prior art is solved. This controls the burrs on the stamped parts within 0.05-0.08mm, eliminates dent deformation, and effectively improves the product qualification rate. Second, the inclined surface contact and dynamic correction design of the horizontal mechanism 3 compensates for the deficiency in the prior art where the horizontal deviation of the mold caused by installation errors and table deformation cannot be adjusted in real time. This reduces abnormal wear on the equipment guide rails and mold cutting edges, extends the mold service life, and reduces equipment maintenance costs. Finally, the linkage and adaptation structure of the entire device replaces the complex operation of disassembling and replacing multiple guide components when changing molds in the prior art. This shortens the mold changing time, improves production efficiency, and reduces the reliance on the experience of the operators. Ordinary technicians can complete high-precision adjustments after simple training, significantly improving the stability and economy of the production process.
