Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a stainless steel metal powder metallurgy forming die. Background Art

[0002] Powder metallurgy forming is a technology that processes metal powder or a mixture of metal powder and non-metallic powder into products of desired shape and size through pressure. Powder metallurgy forming process is a technology for manufacturing metal materials and composite materials. It mainly presses and sinters metal powder (or a mixture of metal powder and other materials) according to a certain mold shape to produce parts and products of desired shape and size.

[0003] In the prior art, when powder metallurgy forming molds are used to manufacture metal parts, the pressure of the powder press is too large or unbalanced, resulting in uneven force on the iron powder, causing local cooling and too fast solidification, or there are foreign objects in the mold, resulting in increased friction between the iron powder and the mold surface or incomplete shape, which can easily cause metal powder to stick to the punch. For example, a punch with a square shape and a flat stamping contact surface will have a small amount of metal powder sticking to the surface of the punch when the metal powder is pressed together with the mold. Under the conditions of small-batch production of metal products, the most common cleaning method is to manually use tools such as brushes or compressed air spray guns to clean the punch regularly. Although this can also clean the punch, manual cleaning of the punch requires stopping the machine or slowing down the production speed during the cleaning process, which leads to a decrease in production efficiency. The quality of manual cleaning will fluctuate due to factors such as the operator's skill level, mood and fatigue level, affecting the quality of subsequent stamping parts. Summary of the invention

[0004] The utility model aims to provide a stainless steel metal powder metallurgy forming die to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Includes cleaning box for cleaning;

[0007] The cleaning box is composed of a cleaning cloth strip and a cleaning sponge block. The cleaning cloth strip cleans by fitting and sliding repeatedly on the stamping surface of the stamping head. The cleaning sponge block is provided with a groove inside. The space size of the groove is adapted to the size of the stamping head. The cleaning sponge block realizes the purpose of rotating and cleaning the surface around the stamping head through the power of the cleaning driving component. The problem in the prior art that manual cleaning of the punch head requires stopping the machine or slowing down the production speed, thereby reducing production efficiency, and the quality of cleaning fluctuates due to factors such as the operator's skill level, mood and fatigue, which affects the quality of subsequent stamping parts, is solved.

[0008] Preferably, the cleaning driving component is composed of a second motor, a driving roller, a belt, a driven roller, a base and a connecting rod. On the other side inside the cleaning box, a second motor is fixedly connected. The output end of the second motor is fixedly connected with the driving roller. The outside of the driving roller is drivingly connected with the belt. The belt is drivingly connected with the driven roller. The lower part of the driven roller is connected with the base. The central part above the driven roller is connected with the connecting rod. One end of the connecting rod is connected with a fixing block, and a cleaning sponge block is arranged inside the fixing block.

[0009] Preferably, a platform is arranged below the cleaning box. On both sides inside the platform, a first motor is fixedly connected. The output end of the first motor is connected with a threaded rod. The threaded rod penetrates through and is in threaded connection with a slider. Since the output end of the first motor is connected with one end of the threaded rod, after the first motor starts to operate, it can drive the threaded rod to rotate, and the slider located outside the threaded rod slides as the threaded rod rotates.

[0010] Preferably, a hydraulic rod is fixedly connected above the slider. The extending end of the hydraulic rod is connected with a connecting plate. The cleaning box is fixedly connected to the middle part above the connecting plate. A dust collection groove is arranged on one side inside the cleaning box. Vertical plates are fixedly connected to both sides inside the dust collection groove. Above one side of the vertical plate, a fixing plate is fixedly connected. The fixing plate is connected with one side of the cleaning cloth strip. Since the hydraulic rod is connected above the slider, when the slider moves horizontally, the hydraulic rod also moves accordingly. Since the extending end of the hydraulic rod is connected with the connecting plate, the hydraulic rod can control the connecting plate to lift. After the cleaning cloth strip inside the cleaning box contacts the stamping surface of the stamping head, it wipes and cleans the stamping surface following the back-and-forth sliding movement of the slider.

[0011] Preferably, a support rod is fixedly connected above the platform. The top of the support rod is connected with a top plate. The support rod is located above the platform and is used to support the stamping component, so that the device can maintain stability when stamping the mold.

[0012] Preferably, a cylinder is fixedly connected above the top plate. The extending end of the cylinder penetrates through the top plate and is fixedly connected with a stamping head. The cylinder is connected above the top plate, and the bottom plate is connected with the support rod below, so that the top plate can maintain a certain stability when the cylinder operates. The cylinder controls the stamping head to descend to stamp the metal powder in the mold.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, after the stamping device finishes stamping the metal powder in the mold each time, a small amount of powder or particulate matter is likely to adhere to the stamping surface of the stamping head. The upper surface of the cleaning cloth strip in the cleaning box fits against the edge position of the stamping surface of the stamping head. During the movement of the cleaning cloth strip, it closely fits against the stamping surface, thereby enabling the wiping of the entire stamping surface. The peripheral surface of the stamping head is wrapped by sponge blocks, and through the cleaning drive assembly, the cleaning sponge blocks can repeatedly clean the peripheral surface of the stamping head, facilitating the next stamping under the premise that the stamping head remains clean. Therefore, the cleaning box in this application can simply and efficiently clean the punch without stopping the machine. In this way, it solves the problems in the prior art that manual cleaning of the punch requires stopping the machine or slowing down the production speed, resulting in a decrease in production efficiency, and the quality of cleaning fluctuates due to factors such as the skill level, mood, and fatigue degree of the operator, affecting the quality of subsequent stamped parts.

[0027] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0028] including a cleaning cartridge 24 for cleaning;

[0029] The cleaning cartridge 24 is composed of a cleaning cloth strip 20 and a cleaning sponge block 19. The cleaning cloth strip 20 is cleaned by fitting and repeatedly sliding on the stamping surface of the stamping head 5. A groove is provided inside the cleaning sponge block 19, and the size of the groove space is adapted to the size of the stamping head 5. The cleaning sponge block 19 rotates to clean the surface around the stamping head 5 through the power of the cleaning drive component 6.

[0030] During use, after the stamping device stamps the metal powder in the mold each time, a small amount of powder or particles are likely to adhere to the stamping surface of the stamping head 5. The upper surface of the cleaning cloth strip 20 in the cleaning cartridge 24 fits to the edge position of the stamping surface of the stamping head 5. During the movement of the cleaning cloth strip, it fits tightly with the stamping surface, so that the entire stamping surface can be wiped. The peripheral surface of the stamping head 5 is wrapped by the sponge block. Through the cleaning drive assembly, the cleaning sponge block 19 can repeatedly clean the peripheral surface of the stamping head 5, facilitating the next stamping on the premise that the stamping head 5 remains clean. Therefore, the cleaning cartridge 24 in the present application can simply and efficiently clean the punch without stopping the machine. In this way, the problems in the prior art that manual cleaning of the punch requires stopping the machine or slowing down the production speed, resulting in a decrease in production efficiency, and the cleaning quality fluctuates due to factors such as the skill level, mood, and fatigue degree of the operator, affecting the quality of subsequent stamped parts are solved.

[0031] In a further preferred embodiment, the cleaning drive component 6 is composed of a second motor 12, a driving roller 15, a belt 16, a driven roller 14, a base 13, and a connecting rod 17. The other side inside the cleaning cartridge 24 is fixedly connected with the second motor 12. The output end of the second motor 12 is fixedly connected with the driving roller 15. The outside of the driving roller 15 is drivingly connected with the belt 16. The belt 16 is drivingly connected with the driven roller 14. The lower part of the driven roller 14 is connected with the base 13. The central part above the driven roller 14 is connected with the connecting rod 17. One end of the connecting rod 17 is connected with a fixing block 18, and the cleaning sponge block 19 is arranged inside the fixing block 18.

[0032] In the present application, when the second motor 12 operates, it drives the driving roller 15 and the belt 16 outside the roller to rotate together. The driven roller 14 drivingly connected with the belt 16 also rotates accordingly. Thus, the connecting rod 17 located at the central part of the driven roller 14 can drive the fixing block 18 and the cleaning sponge block 19 inside the fixing block 18 to rotate together. When the stamping head 5 is inserted into the groove inside the cleaning sponge block 19, it is wrapped by the sponge layer, so that the stamping surface of the stamping head 5 can be cleaned.

[0033] In a further preferred embodiment, a platform 1 is provided below the cleaning box 24. On both sides inside the platform 1, a first motor 10 is fixedly connected. The output end of the first motor 10 is connected to a threaded rod 11, and the threaded rod 11 penetrates and is threadedly connected to a slider 9.

[0034] In this application, since the output end of the first motor 10 is connected to one end of the threaded rod 11, after the first motor 10 starts to operate, it can drive the threaded rod 11 to rotate. The slider 9 located outside the threaded rod 11 slides as the threaded rod 11 rotates. The output end of the first motor 10 can adjust the rotation direction and is applicable to forward or reverse rotation. Correspondingly, the rotation direction of the threaded rod 11 also changes accordingly, and the slider 9 can perform reciprocating motion on the threaded rod 11.

[0035] In a further preferred embodiment, a hydraulic rod 8 is fixedly connected above the slider 9. The extending end of the hydraulic rod 8 is connected to a connecting plate 7. The cleaning box 24 is fixedly connected to the middle part above the connecting plate 7. On one side inside the cleaning box 24, a dust collection groove 23 is provided. On both sides inside the dust collection groove 23, vertical plates 21 are fixedly connected. Above one side of the vertical plate 21, a fixing plate 22 is fixedly connected. The fixing plate 22 is connected to one side of the cleaning cloth strip 20.

[0036] In this application, the hydraulic rod 8 is connected above the slider 9. Therefore, when the slider 9 performs reciprocating motion above the threaded rod 11, the hydraulic rod 8 also moves accordingly. Since the extending end of the hydraulic rod 8 is connected to the connecting plate 7, the hydraulic rod 8 can control the lifting of the connecting plate 7. At the same time, the connecting plate 7 also moves along with the displacement direction of the slider 9. After the cleaning cloth strip 20 inside the cleaning box 24 contacts the stamping surface of the stamping head 5, it wipes and cleans the stamping surface following the reciprocating sliding action of the slider 9. During the wiping process, the particulate impurities attached to the stamping surface fall into the dust collection groove 23 and are collected uniformly.

[0037] In a further preferred embodiment, a support rod 2 is fixedly connected above the platform 1, and the top of the support rod 2 is connected to a top plate 4.

[0038] In this application, multiple support rods 2 are provided above the platform 1. On each side of the platform 1, two support rods 2 with the same spacing are respectively provided. The support rods 2 are located above the platform 1 and are used to support the stamping components, so that the device can remain stable during stamping.

[0039] In a further preferred embodiment, a cylinder 3 is fixedly connected above the top plate 4. The extending end of the cylinder 3 penetrates the top plate 4 and is fixedly connected to a stamping head 5.

[0040] In this application, the cylinder 3 is connected above the top plate 4, and the bottom of the top plate 4 is connected to the support rod 2. When the stamping head 5 stamps downward on the mold, certain vibrations will be generated. The combination of the top plate 4 and the support rod 2 ensures a certain stability when the cylinder 3 operates. The cylinder 3 controls the descent of the stamping head 5 to stamp the metal powder in the mold.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
