Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a fast positioning clamping mold for punching processing of top chips. Background Art

[0002] The utility model relates to a technical field in which the top chip of the oil cooler is one of its core components. It is a long strip of plate with double round heads and two round holes with flanges on its surface. Its main function is to provide support and stability for the structure of the oil cooler and to provide a positioning base point for the installation of flanges and other components. The flange design on the top chip enables it to be precisely docked with the round holes of the flange, thereby ensuring that the flange is fixed in the correct position to avoid arbitrary rotation. The flange usually has a certain angle design, so through the structural positioning of the top chip, not only can the assembly angle of the oil cooler be guaranteed to be accurate, but also the overall stability and deformation resistance can be improved. The top chip needs to have high strength and high temperature resistance to maintain reliability in a complex working environment. Its flange design further enhances the positioning and pressure-bearing ability of the structure, and is an indispensable key part in the oil cooler.

[0003] The stamping clamping die for fast positioning of the top chip has multiple core functions. It can quickly and accurately fix the top chip in the correct position through precise positioning pins or positioning blocks, thereby avoiding assembly problems caused by deviations and improving processing efficiency. At the same time, its clamping mechanism can firmly fix the top chip during the stamping process to prevent slippage and deformation, ensuring the consistency and accuracy of processing. In addition, the design of the die fully considers the protection of the key parts of the top chip (such as the round hole of the flange), and avoids damage to the flange shape during processing through a reasonable structure and matching stamping parts, significantly improving the quality and stability of the finished product.

[0004] The significance of this type of mold is reflected in many aspects. Through rapid positioning and efficient clamping, it not only significantly improves production efficiency, but also reduces human errors and workpiece defect rates, thereby ensuring the accuracy and stability of product assembly. In addition, its high precision and automation characteristics promote the standardization and mass production of manufacturing systems, reducing overall production costs. More importantly, while ensuring the quality of top chip processing, this mold also indirectly improves the reliability of the entire oil cooler, bringing higher benefits and automation development space to modern industrial production lines.

[0022] Preferably, the spring plate structure includes a pair of plate withdrawal sleeves 9, which are slidably installed on the fixed hole tube 5 and the sliding hole tube 6 respectively, and a reset spring 10 is connected between the pair of plate withdrawal sleeves 9 and the fixed hole tube 5 and the sliding hole tube 6 respectively, and the pair of plate withdrawal sleeves 9 are higher than the upper ends of the fixed hole tube 5 and the sliding hole tube 6.

[0025] A fillet surface 21 is provided at the upper end of the discharge hole 11 on the fixed hole tube 5 and the sliding hole tube 6. A flanging sleeve 22 is fixedly installed between the punching body 13 and the fixed punch 7 and the sliding punch 8. In the prior art, the flanging formed by punching the top chip is a round hole without a protrusion for positioning. The punching formed by the fillet surface 21 and the flanging sleeve 22 can be provided with an additional protruding flanging. The flange is installed on the top chip. The installation of the flange requires a certain angle. The connection between it and the top chip is a round hole. The flanging provided on the top chip is used to connect with the flange, and the flanging is installed in the round hole of the flange. In the prior art, there is no positioning structure on the top chip, so the flange will rotate on the top chip and the angle cannot be determined. The present technical solution punches a convex structure at the flanging part of the top chip for positioning the flange angle. A rounded surface 21 is provided at the upper end of the discharge hole 11 on the fixed hole cylinder 5 and the sliding hole cylinder 6, and a flanging sleeve 22 is fixedly installed between the punching body 13 and the fixed punch 7 and the sliding punch 8. The flanging sleeve 22 and the rounded surface 21 are provided with convex grooves. The operator installs the convex grooves corresponding to the convex grooves on the mounting flange, so that the flanging on the top chip after stamping is provided with convexities. The number of convexities can be adjusted and customized, and different specifications and sizes can be adopted according to needs to correspond to the external flange to prevent the flange and the top chip from rotating relative to each other.

[0026] The detailed connection means are well known in the art; Figure 1-5 As shown, the upper mold 2 and the lower mold 1 are installed on the punching machine table and aligned, and the upper and lower molds 1 are accurately aligned through the corresponding structure (including the corresponding block 17, the corresponding head 18 and the positioning head 20) to ensure that the positioning of both sides is accurate.

[0027] According to the hole pitch specifications of the top chip to be processed, the adjustment motor 14 in the sliding distance adjustment structure is started. The adjustment motor 14 drives the threaded rod 16 to rotate, driving the threaded sleeve 15 to move, so that the sliding hole cylinder 6 and the sliding punch 8 are adjusted along the slide rail. At the same time, the fixed hole cylinder 5 and the fixed punch 7 are kept in a fixed position to flexibly adapt to different top chip specifications.

[0028] Ensure that the spring plate structure (including the plate withdrawal sleeve 9 and the return spring 10) and the discharge holes 11 and the discharge grooves 12 are normal, and ensure that the mold works without obstruction.

[0029] The top chip sheet to be processed is placed into the positioning groove 23 on the plate withdrawal sleeve. The positioning groove 23 is a semicircular groove. The positioning groove 23 can be selected according to the actual needs of the current batch of top chips, and is used to quickly position the top chip, align the positions of the fixed hole cylinder 5 and the sliding hole cylinder 6, and ensure that the hole position of the top chip corresponds to the operating position of the punch in the mold.

[0030] After the top chip is in place, the plate-retracting sleeve 9 in the spring plate structure exerts a clamping force on the top chip under the action of the return spring 10, and firmly fixes the top chip plate in the processing position to prevent slippage or displacement during the stamping process.

[0031] The punching machine is started, and the fixed punch 7 and the sliding punch 8 move from top to bottom, and the holes of the top core sheet are punched under the action of the punching body 13 .

[0032] Since the die is designed with a flange sleeve 22 between the fixed punch 7 and the sliding punch 8, the edge of the top core hole is raised by the punching process of the rounded corner surface 21, forming a round hole with a raised flange. The design of this raised edge provides angle positioning for the subsequent flange installation, avoiding the problem of random rotation during flange installation.

[0033] The waste materials after stamping are discharged into the discharge groove 12 of the lower mold 1 through the discharge holes 11 on the fixed hole cylinder 5 and the sliding hole cylinder 6, and discharged from the outside of the mold to ensure the cleanliness of the processing area.

[0034] After the punching is completed, the reset spring 10 drives the plate withdrawal sleeve 9 to lift up, and the top chip plate is released from the clamping state for easy removal. Check whether the protrusion of the top chip flange hole after punching reaches the expected specification to ensure the stability of the flange and the accuracy of the angle, thereby meeting the flange installation requirements.

[0035] If you want to process top chips of the same specification continuously, repeat the workpiece positioning and stamping operations; if you need to process top chips of other specifications, you can readjust the sliding distance adjustment structure to adapt to the new hole spacing requirements. Clean the discharge groove 12 and sliding parts of the mold to prevent waste residue from affecting the accuracy and sliding smoothness.

[0036] Check the wear of the adjusting motor 14, the threaded sleeve 15 and the threaded rod 16 to ensure the long-term reliability of the pitch adjustment system.

[0037] Keep the flanging sleeve 22 and the surface of the punching part clean and free of oil, and regularly check whether the cutting edge of the punching body 13 is intact to ensure high-quality flanging forming effect.
