Description

Technical Field

[0001] This utility model relates to the field of mold steel processing technology, and in particular to a rolling equipment for high-precision mold steel processing. Background Technology

[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Mold materials are the material and technological foundation of the mold manufacturing industry. Among them, mold steel is a traditional mold material, and its variety, specifications, and quality play a decisive role in the performance, service life, and manufacturing cycle of the mold. Rolling is an important deformation processing method in mold steel processing. By applying pressure to the mold steel through rolls, it undergoes plastic deformation between the rolls, thereby changing its shape, size, and properties.

[0003] During the rolling process of mold steel, a large amount of oxide layer will form on the surface of the heated mold steel. After being rolled by the rolls, the oxide layer will fall off. When the oxide layer falls off, it will continue to move to the position of the next roll as the mold steel moves. During the subsequent rolling, the oxide layer will be squeezed. A large amount of oxide layer will occupy a certain thickness, and the surface of the rolled mold steel will have marks or unevenness, which will affect the rolling of the mold steel. Therefore, a rolling equipment for high-precision mold steel processing is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rolling equipment for high-precision mold steel processing, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rolling mill for high-precision die steel processing includes two sets of rolling supports. Each set of rolling supports is rotatably mounted with a set of drive shafts. A first rolling roll and a second rolling roll are respectively arranged on the two sets of drive shafts. A die steel body is arranged between the first rolling roll and the second rolling roll. A conveyor belt is installed on the rolling support through a drive transmission assembly. A scraper is installed on the conveyor belt. The bottom of the scraper located at the bottom contacts the top of the die steel body. A cooling assembly is arranged on one side of the rolling support, and the cooling assembly is adapted to the scraper.

[0007] Preferably, the drive transmission assembly includes a driven shaft and a driving shaft fixedly mounted on the rolling support, with rotating rollers fixedly sleeved on both the driving shaft and the driven shaft, and conveyor belts provided on the two rotating rollers.

[0008] Preferably, a first bevel gear is fixedly sleeved on the drive shaft, and a second bevel gear is fixedly sleeved on the end of the drive shaft, with the first bevel gear and the second bevel gear meshing with each other.

[0009] Preferably, a connecting seat is installed on the conveyor belt, and a scraper is installed on the connecting seat.

[0010] Preferably, the cooling component includes a water tank fixedly installed on the side of the rolling support, a pump body is provided inside the water tank, a fixed pipe is connected to the pump body, and an atomizing spray pipe is connected to one end of the fixed pipe.

[0011] Preferably, the atomizing nozzle is located at the end of the conveyor belt, and the water tank is provided with an inlet.

[0012] Preferably, a collection frame is provided on one side of the rolling support, the collection frame is located below the conveyor belt and on the side of the mold steel body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the rolling equipment for high-precision mold steel processing is equipped with rolling rolls that can roll the mold steel body. After being squeezed by the first rolling roll, the oxide layer on the surface of the mold steel will fall off or separate. The drive transmission component can drive the conveyor belt to rotate, thereby driving the scraper to move. The scraper located below scrapes away the separated oxide layer and collects it in the collection frame on one side, avoiding the oxide layer from moving with the mold steel body into the second rolling roll, causing the mold steel body to have an uneven surface or marks after rolling. The rolled mold steel body is more precise.

[0014] The cooling component is designed to cool the scraper and conveyor belt by drawing water from the water tank and spraying it out through the atomizing nozzle during long-term scraping operations, thus preventing damage to the scraper and conveyor belt caused by continuous high temperatures.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4 A high-precision rolling mill for machining mold steel includes two sets of rolling supports 1, each set of rolling supports 1 having a drive shaft 2 rotatably mounted on it. A first rolling roll 3 and a second rolling roll 4 are respectively mounted on the two drive shafts 2. A mold steel body 5 is positioned between the first rolling roll 3 and the second rolling roll 4. The mold steel body 5 is made of NAK80 mold steel, a pre-hardened plastic mold steel. NAK80 mold steel is mainly used for mirror-polished molds, with a hardness of 32-43 HRC, and possesses excellent polishability, carving properties, and electrical discharge machining capabilities, requiring no heat treatment. It has good polishability, machinability, and etching properties, making it suitable for high-precision mirror molds. It is a high-precision mold steel. After being heated, the mold steel body 5 passes through a set of first rolling rolls 3 and second rolling rolls 4 in sequence. Through the extrusion of the rolling rolls, its shape can be changed, thereby changing its properties. A conveyor belt 11 is installed on the rolling support 1 through a drive transmission assembly. A scraper 13 is installed on the conveyor belt 11. The bottom of the scraper 13 located below contacts the top of the mold steel body 5. A cooling assembly is provided on one side of the rolling support 1, and the cooling assembly is adapted to the scraper 13.

[0022] Furthermore, the drive transmission assembly includes a driven shaft 6 and a drive shaft 7 fixedly mounted on the rolling support 1. Rotating rollers 10 are fixedly sleeved on both the drive shaft 7 and the driven shaft 6. Conveyor belts 11 are provided on the two rotating rollers 10. A first bevel gear 8 is fixedly sleeved on the drive shaft 2, and a second bevel gear 9 is fixedly sleeved at the end of the drive shaft 7. The first bevel gear 8 and the second bevel gear 9 mesh with each other. After being squeezed by the first rolling roller 3, their shape, size, and performance are changed. After rolling, the oxide layer will fall off or separate. The oxide layer located at the top cannot fall off. At this time, the drive transmission assembly, after the first bevel gear 8 and the second bevel gear 9 mesh with each other, can drive the drive shaft 7 to rotate, thereby driving the rotating rollers 10 to rotate, and driving the conveyor belt 11 to rotate. The conveyor belt 11 is a heat-resistant conveyor belt with good heat resistance. The heat resistance temperature is between 100℃ and 250℃. After the conveyor belt 11 rotates, it will drive the scraper 13 to move.

[0023] Furthermore, a connecting seat 12 is installed on the conveyor belt 11, and a scraper 13 is installed on the connecting seat 12. A collection frame 14 is provided on one side of the rolling support 1. The collection frame 14 is located below the conveyor belt 11 and on the side of the mold steel body 5. The connecting seat 12 is wider than the scraper 13, which can stably fix the scraper 13. The scraper 13 has a better effect on removing the oxide layer. After the scraper 13 located below rotates, it can contact the top of the mold steel body 5. At this time, the separated oxide layer will be scraped away by the scraper 13 and collected in the collection frame 14 on one side. By effectively scraping away the oxide layer that falls on the mold steel body 5, the oxide layer is prevented from moving with the mold steel body 5 into the second rolling roll 4, which would cause unevenness or marks on the surface of the mold steel body 5 after rolling. The rolled mold steel body 5 is more precise.

[0024] Furthermore, the cooling component includes a water tank 15 fixedly installed on the side of the rolling support 1. A pump body 16 is installed inside the water tank 15, and a fixed pipe 17 is connected to the pump body 16. One end of the fixed pipe 17 is connected to an atomizing spray pipe 18, which is located at the end of the conveyor belt 11. The water tank 15 is provided with an inlet. The scraper 13 is made of metal steel and will come into contact with the mold steel body 5 during the scraping process. The temperature is high due to prolonged contact. At this time, the pump body 16 on the cooling component is started to run, and the water in the water tank 15 is drawn out and sprayed out from the atomizing spray pipe 18 to spray water to cool the scraper 13 and the conveyor belt 11, so as to avoid damage to the scraper 13 and the conveyor belt 11 due to continuous high temperature.

[0025] In use: The mold steel body 5 needs to undergo a rolling process during production. After being squeezed by the first rolling roll 3, its shape, size and performance are changed. After rolling, the oxide layer will fall off or separate. After the first bevel gear 8 and the second bevel gear 9 mesh and drive, they can drive the conveyor belt 11 to rotate. The conveyor belt 11 is a heat-resistant conveyor belt, which drives the scraper 13 to move. The separated oxide layer will be scraped off by the scraper 13 and collected in the collection frame 14 on one side. By effectively scraping off the oxide layer that falls off the mold steel body 5, the oxide layer is prevented from moving with the mold steel body 5 into the second rolling roll 4, which would cause unevenness or marks on the surface of the mold steel body 5 after rolling. The rolled mold steel body 5 is more precise. During the scraping process, the pump body 16 is started and the water in the water tank 15 is sprayed out from the atomizing nozzle 18 to spray water to cool the scraper 13 and the conveyor belt 11, avoiding damage to the scraper 13 and the conveyor belt 11 due to continuous high temperature. It is easy to use.
