Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal stamping processing technology, and specifically relates to a cleaning mechanism for metal stamping processing. Background Technology
[0002] Metal stamping parts are metal parts made through cold stamping. They are formed by applying pressure to metal sheets using molds to create specific shapes. They are characterized by light weight, high precision, and high production efficiency.
[0003] Currently, Chinese utility model patent CN216324571U discloses a waste material cleaning device for stamping dies. In existing metal stamping processes, metal waste is stamped out during hole punching. Large pieces of waste are guided into the punching groove by the force of the punch and fall downwards into the die groove to prevent affecting the die's use. However, during the handling of metal stamping parts, small pieces of metal waste can easily fall into the die groove, making them difficult to detect and clean. This can cause unevenness inside the die, affecting the stamping accuracy of subsequent metal stamping processes. Furthermore, although large pieces of stamping waste can fall out of the die groove, they are difficult to collect uniformly, thus hindering subsequent waste recycling. Utility Model Content
[0004] The purpose of this utility model is to provide a cleaning mechanism for metal stamping parts processing. Its advantage is that it facilitates the cleaning and unified collection of metal waste produced by metal stamping parts processing, and makes it convenient for subsequent recycling of the waste.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning mechanism for processing metal stamping parts, including a base plate, a stamping seat bolted to the top of the base plate, a placement groove opened on the top of the stamping seat, a brush plate slidably connected inside the placement groove, sliding blocks bolted to both ends of the brush plate, a pull rod welded to one side of each of the two sliding blocks and slidably connected through the stamping seat, a spring sleeved on the surface of the pull rod at one end inside the stamping seat, and the two ends of the spring being bolted to the stamping seat and the sliding block respectively.
[0006] The above technical solution involves pulling the lever outwards to slide the brush plate inside the placement groove, sweeping out small metal scraps from the groove. This effectively cleans the stamped metal scraps, preventing them from remaining inside the mold and affecting subsequent processing. By directly stamping and cleaning the metal scraps from metal stamping, they are collected and stored inside the sliding box. This facilitates the unified collection and recycling of stamping waste, improving practicality.
[0007] The present invention is further configured such that a stamping hole is provided at the bottom of the inner cavity of the placement groove, a sliding box is slidably connected inside the stamping seat, a storage groove communicating with the bottom of the stamping hole is provided at the top of the sliding box, and a groove cooperating with the sliding box is provided on the side of the placement groove away from the brush plate.
[0008] The above technical solution facilitates the unified collection and recycling of stamping waste, thus improving its practicality.
[0009] The present invention is further provided that mounting holes are opened at all four corners of the base plate.
[0010] Using the above technical solution, the base plate and the stamping seat can be fixedly installed by passing bolts through the mounting holes and tightening them with nuts.
[0011] The present invention is further configured such that each of the two pull rods is welded with a pull block at the end away from the sliding block, and the surface of the pull block is provided with anti-slip texture.
[0012] The above technical solution increases the friction on the surface of the pull block, making it easier to pull the pull rod outward.
[0013] The present invention is further configured such that a handle is bolted to the side of the sliding box away from the interior of the stamping seat.
[0014] The above technical solution facilitates sliding the sliding box out of the stamping seat by pulling the handle.
[0015] The present invention is further configured such that magnet blocks that are magnetically attracted to each other are bolted to the sides of the sliding box and the stamping seat that are close to each other.
[0016] Using the above technical solution, the magnetic force of the magnet can be used to fix the sliding box inside the stamping seat to prevent it from slipping off automatically.
[0017] The present invention is further provided that the storage slot has an inclined groove on the side near the handle inside.
[0018] The above technical solution facilitates the downward movement of small waste materials swept out by the brush plate from inside the groove, and then allows them to slide into the storage compartment through the inclined groove.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. By pulling the lever outward, the brush plate slides inside the placement groove, sweeping out small pieces of metal scrap from the groove. This cleans up the small metal scrap produced during stamping, preventing it from remaining inside the mold and affecting subsequent processing.
[0021] 2. By directly stamping and cleaning the metal scrap generated during the stamping process, the scrap metal is collected and stored inside the sliding box. This facilitates the subsequent unified collection and recycling of stamping waste, improving its practicality. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Example 1:
[0029] refer to Figure 1 , Figure 2 , Figure 3 A cleaning mechanism for metal stamping parts processing includes a base plate 1, a stamping seat 2 bolted to the top of the base plate 1, a placement groove 3 formed on the top of the stamping seat 2, a brush plate 5 slidably connected inside the placement groove 3, and sliding blocks 8 bolted to both ends of the brush plate 5. A pull rod 6, which passes through and slidably connects to the stamping seat 2, is welded to one side of each of the two sliding blocks 8. A spring 7 is fitted onto the surface of the pull rod 6 at its inner end in the stamping seat 2, and both ends of the spring 7 are bolted to the stamping seat 2 and the sliding blocks 8, respectively. By pulling the pull rod 6 outwards, the brush plate 5 slides inside the placement groove 3, causing small metal scraps inside the placement groove 3 to be swept out by the brush plate 5. This effectively cleans the small metal scraps produced during stamping, preventing them from remaining inside the mold and affecting subsequent processing.
[0030] refer to Figure 1 , Figure 2 The base plate 1 has mounting holes 12 at each of its four corners. Bolts can be passed through the mounting holes 12 and tightened with nuts to fix the base plate 1 and the stamping seat 2 in place.
[0031] refer to Figure 1 , Figure 2 Each of the two pull rods 6 has a pull block 13 welded to the end furthest from the sliding block 8. The surface of the pull block 13 has anti-slip texture to increase the friction of the pull block 13 surface, making it easier to pull the pull rod 6 outward.
[0032] Brief description of usage: By placing the metal stamping part inside the placement groove 3, the stamping points of the punch and the metal stamping part, as well as the stamping hole 4, are kept vertically aligned. When the punch moves downward to punch holes in the metal stamping part, the punched waste material will fall downward through the stamping hole 4 and be automatically discharged into the placement groove 3. At the same time, when small metal scraps fall into the placement groove 3 while removing the metal stamping part, pulling the lever 6 will drive the sliding block 8 to overcome the elastic force of the spring 7, causing the brush plate 5 to slide inside the placement groove 3 to clean. This sweeps the metal scraps that have fallen into the placement groove 3 outward. After cleaning, the lever 6 is released, and the spring 7's rebound force will push the brush plate 5 to automatically reset.
[0033] Example 2:
[0034] refer to Figure 1 , Figure 3 , Figure 4 This is a cleaning mechanism for metal stamping parts processing. A stamping hole 4 is provided at the bottom of the inner cavity of the placement groove 3. A sliding box 9 is slidably connected inside the stamping base 2. A storage groove 11, communicating with the bottom of the stamping hole 4, is provided on the top of the sliding box 9. A groove 15, cooperating with the sliding box 9, is provided on the side of the placement groove 3 away from the brush plate 5. Metal scrap generated during the stamping process is collected and stored inside the sliding box 9 through direct stamping and cleaning. This facilitates the subsequent unified collection and recycling of stamping scrap, improving its practicality.
[0035] refer to Figure 1 , Figure 4 A handle 14 is attached to the side of the sliding box 9 away from the inside of the stamping base 2. This allows the sliding box 9 to be slid out of the inside of the stamping base 2 by pulling the handle 14.
[0036] refer to Figure 3 , Figure 4 Both the sliding box 9 and the stamping base 2 have magnet blocks 10 attached to their respective sides, which are close to each other. The magnetic attraction of the magnet blocks 10 can be used to fix the sliding box 9 inside the stamping base 2 to prevent it from slipping off automatically.
[0037] refer to Figure 3 , Figure 4 The storage compartment 11 has a sloping groove 16 on the side near the handle 14. This allows small waste materials swept out by the brush plate 5 to fall down from the groove 15 and then slide into the storage compartment 11 through the sloping groove 16.
[0038] Brief description of the usage process: Large pieces of metal scrap produced by stamping fall downwards from the inside of the stamping hole 4 and into the storage slot 11, where they are collected and stored inside the sliding box 9. Simultaneously, when the brush plate 5 cleans the small pieces of metal scrap inside the placement slot 3, the groove 15 also sweeps these small pieces into the sliding box 9 for storage. This ensures that all the waste produced during the stamping process of metal parts can be cleaned into the sliding box 9, facilitating subsequent unified collection and recycling of the waste.
[0039] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
