Description

Technical Field

[0001] The utility model relates to the field of stamping dies, and particularly relates to a stamping die for metal sheets. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing. In the process of producing hardware parts, there are also many hardware parts that need to be made by stamping sheet metal materials with a stamping die. As a commonly used device for producing hardware parts, the stamping die has developed at a relatively fast speed. During the storage, transportation, and use of the sheet metal materials for producing hardware parts, some dust and sundries often adhere to them. When the sheet metal materials enter the stamping die, the dust and sundries adhering to them will also enter the stamping die. Thus, as the sheet metal materials are stamped, the dust and sundries adhering to them are easily shaken and fall into the stamping die. Over time, the holes and grooves on the stamping die are easily blocked by the dust and sundries, which will ultimately affect the stamping of the sheet metal materials and thus reduce the production efficiency of the hardware parts. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a stamping die for metal sheets, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A stamping die for metal sheets includes a lower die and an upper die. An installation bracket is installed on the lower die. The installation bracket is composed of an installation frame and an L-shaped bracket. There are two L-shaped brackets, which are symmetrically and fixedly installed at the lower end of the installation frame. Two cleaning components are symmetrically installed on the installation frame. The cleaning component is composed of a cleaning scraper, a threaded rod, a rotating plate, a support substrate, a support spring, and a wiping sponge. The threaded rod is rotatably installed at the lower end of the cleaning scraper. The rotating plate is fixedly installed at the lower end of the threaded rod. There are two support springs, which are symmetrically and fixedly installed inside the cleaning scraper. The support substrate is fixedly installed at one end of the two support springs. The wiping sponge is fixedly installed at one end of the support substrate.

[0006] Preferably, the installation frame on the installation bracket is located on one side of the lower die. Two threaded holes are symmetrically opened on the upper and lower wall bodies of the installation frame, and the two threaded holes penetrate the upper and lower wall bodies of the installation frame respectively.

[0007] Preferably, the L-shaped bracket on the installation bracket is fixedly connected to the lower die.

[0008] Preferably, the cleaning scraper on the cleaning component is located inside the installation frame, and an installation groove is opened on the cleaning scraper.

[0009] Preferably, the threaded rod on the cleaning assembly is simultaneously installed in the threaded holes opened on the mounting frame, and the rotating plate is located outside the mounting frame.

[0010] Preferably, the support substrate, the support spring and the wiping sponge on the cleaning assembly are all located in the installation groove opened on the cleaning scraper, and the support spring is fixedly connected to the inner wall of the installation groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By arranging a mounting bracket on the lower die and a cleaning assembly on the mounting bracket, the cleaning scraper on the cleaning assembly can scrape off the dust and sundries attached to the sheet-shaped hardware material. Under the elastic force of the support spring, the wiping sponge on the cleaning assembly will be in full contact with the sheet-shaped hardware material, so that the wiping sponge will further clean the sheet-shaped hardware material, thereby ensuring that the sheet-shaped hardware material entering the lower die can maintain a relatively clean state. Finally, the probability of the holes and grooves opened on the lower die being blocked by dust and sundries can be reduced, so as to ensure the production efficiency of the hardware parts. The threaded rod on the cleaning assembly can adjust the distance between the two cleaning scrapers, so that the cleaning scraper can closely adhere to the sheet-shaped hardware material, thereby ensuring the cleaning effect of the cleaning scraper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 , Figure 2, Figure 3 , Figure 4 As shown in Figure 4 , a stamping die for metal sheets includes a lower die 1 and an upper die 2. An installation bracket 3 is installed on the lower die 1. The installation bracket 3 is composed of an installation frame 5 and L-shaped brackets 7. There are two L-shaped brackets 7, which are symmetrically and fixedly installed at the lower end of the installation frame 5. Two cleaning components 4 are symmetrically installed on the installation frame 5. The cleaning component 4 is composed of a cleaning scraper 8, a threaded rod 10, a rotating plate 11, a supporting substrate 12, a supporting spring 13 and a wiping sponge 14. The threaded rod 10 is rotatably installed at the lower end of the cleaning scraper 8. The rotating plate 11 is fixedly installed at the lower end of the threaded rod 10. There are two supporting springs 13, which are symmetrically and fixedly installed in the cleaning scraper 8. The supporting substrate 12 is fixedly installed at one end of the two supporting springs 13. The wiping sponge 14 is fixedly installed at one end of the supporting substrate 12. The installation frame 5 on the installation bracket 3 is located on one side of the lower die 1. Two threaded holes 6 are symmetrically opened on the upper and lower side walls of the installation frame 5, and the two threaded holes 6 penetrate the upper and lower side walls of the installation frame 5 respectively. The L-shaped bracket 7 on the installation bracket 3 is fixedly connected to the lower die 1. When the lower die 1 and the upper die 2 are in use, they can be fixedly installed on a hydraulic device. When producing metal parts, a sheet-shaped metal material can be inserted into the lower die 1, and then the upper die 2 can be pushed downward by the hydraulic device, so as to complete the stamping of the sheet-shaped metal material by the upper die 2. At the same time, before inserting the sheet-shaped metal material into the lower die 1, the sheet-shaped metal material can be passed through the installation frame 5 on the installation bracket 3, and at the same time, the sheet-shaped metal material needs to pass between the two cleaning scrapers 8 of the two cleaning components 4. During this process, the moving sheet-shaped metal material will rub against the cleaning scraper 8, so that the cleaning scraper 8 will scrape off the dust and debris on the sheet-shaped metal material. When the sheet-shaped metal material passes by the cleaning scraper 8, it will contact the wiping sponge 14 pushed by the supporting spring 13, so that the wiping sponge 14 will further clean the sheet-shaped metal material. Finally, the sheet-shaped metal material that has been cleaned will enter the lower die 1.

[0020] Further, the cleaning scraper 8 on the cleaning component 4 is located in the installation frame 5. An installation groove 9 is opened on the cleaning scraper 8. The threaded rod 10 on the cleaning component 4 is simultaneously installed in the threaded hole 6 opened on the installation frame 5. The rotating plate 11 is located outside the installation frame 5. When the threaded rod 10 is rotated by the rotating plate 11, the threaded rod 10 will move in the threaded hole 6. At this time, the threaded rod 10 will push the cleaning scraper 8 to move, so that the two cleaning scrapers 8 and the two wiping sponges 14 will contact the sheet-shaped metal material.

[0021] Further, the support substrate 12, the support spring 13, and the wiping sponge 14 on the cleaning assembly 4 are all located in the installation groove 9 formed on the cleaning blade 8. The support spring 13 is fixedly connected to the inner wall of the installation groove 9. At the same time, the support spring 13 also pushes the wiping sponge 14 towards the sheet metal material, so that the wiping sponge 14 can closely adhere to the sheet metal material. By providing an installation bracket 3 on the lower die 1 and a cleaning assembly 4 on the installation bracket 3, the cleaning blade 8 on the cleaning assembly 4 can scrape off the dust and debris attached to the sheet metal material. Under the elastic action of the support spring 13, the wiping sponge 14 on the cleaning assembly 4 will be in full contact with the sheet metal material, so that the wiping sponge 14 will further clean the sheet metal material, thereby ensuring that the sheet metal material entering the lower die 1 can remain relatively clean, and finally reducing the probability that the holes and grooves formed on the lower die 1 are blocked by dust and debris, thus ensuring the production efficiency of the hardware parts. The threaded rod 10 on the cleaning assembly 4 can adjust the distance between the two cleaning blades 8, so that the cleaning blade 8 can closely adhere to the sheet metal material, thereby ensuring the cleaning effect of the cleaning blade 8.
