Description

Technical Field

[0001] This utility model relates to the field of mold steel heat treatment technology, and in particular to a quenching device for mold steel heat treatment. Background Technology

[0002] As an indispensable basic material in modern industry, mold steel is widely used in many fields such as automobile manufacturing, aerospace, and electronic equipment. The quality of molds directly determines the precision, performance, and service life of finished products. Quenching treatment, as a key process to improve the comprehensive performance of mold steel, plays a decisive role in improving its hardness, wear resistance, and toughness.

[0003] Traditional quenching equipment involves a complex and time-consuming process when clamping mold steel. When multiple sides of the mold steel need to be quenched, the fixture must be disassembled, the mold flipped, and then re-clamped. This process not only wastes a lot of time and reduces production efficiency, but the frequent clamping operations can also easily lead to inaccurate positioning of the mold steel, affecting the uniformity of quenching and reducing product quality. Furthermore, the skill levels and operating habits of different operators vary, making it difficult to ensure the accuracy and consistency of each clamping and flipping, resulting in large fluctuations in product quality and an increase in scrap rate. Therefore, a quenching device for heat treatment of mold steel is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quenching device for heat treatment of mold steel, which solves the problems mentioned in the background art.

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

[0006] A quenching device for heat treatment of mold steel includes a housing. A quenching component and a cooling component are respectively arranged on the top and one side of the housing. Circular holes are opened on both sides of the housing. Rotating rods are arranged in two circular holes. Clamping components are arranged at the ends of the two rotating rods that are close to each other. First pulleys are fixedly sleeved at the ends of the two rotating rods that are far from each other. Two fixing plates are fixedly installed on one side of the housing. Both fixing plates are opened with circular holes. The same linkage rod is arranged in the two circular holes. Second pulleys are fixedly sleeved at both ends of the linkage rod. A belt is arranged between the two second pulleys and the two first pulleys. A drive component is arranged below the linkage rod.

[0007] Preferably, the quenching assembly includes a bracket fixedly installed on the top side of the housing, the bracket being U-shaped, and a quenching mechanism provided on the bottom side of the bracket.

[0008] Preferably, the cooling assembly includes a water pump fixedly installed on one side of the housing, an extraction pipe fixedly connected to the bottom side of the water pump, the other end of the extraction pipe extending into the housing, a delivery pipe fixedly connected to the top side of the water pump, and a nozzle fixedly connected to the other end of the delivery pipe extending into the housing.

[0009] Preferably, the clamping assembly includes two rotating rods, each with a connecting block fixedly connected to its opposite face. Each connecting block has a through hole, and an electric push rod is fixedly installed on the inner wall of the side of the two through holes that are close to each other. The output ends of the two electric push rods pass through the connecting blocks and each has a threaded groove.

[0010] Preferably, threaded posts are threadedly installed in both threaded grooves, and clamps are fixedly connected to the ends of the two threaded posts that are close to each other, with the two clamps arranged symmetrically.

[0011] Preferably, the drive assembly includes a side plate fixedly installed on one side of the housing, a motor fixedly installed on the bottom side of the side plate, the output end of the motor rotating through the side plate and fixedly connected to a first bevel gear, and a second bevel gear fixedly sleeved on the outside of the linkage rod, the second bevel gear meshing with the first bevel gear.

[0012] Preferably, two second limiting rings are fixedly sleeved on the outer side of the linkage rod. The sides of the two second limiting rings that are far apart from each other are respectively attached to the sides of the two fixed plates that are close to each other. A set of first limiting rings is fixedly sleeved on the outer side of each of the two rotating rods. There are two first limiting rings in each set. The sides of the two sets of first limiting rings that are close to each other are respectively attached to one side of the box and one side of the inner wall.

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

[0014] 1. By placing the mold steel between two clamping plates and starting the electric push rod, the clamping plates quickly complete the clamping. When it is necessary to flip the mold steel, the motor is started, the first bevel gear drives the second bevel gear, causing the linkage rod to rotate. With the help of the belt, the rotating rod flips the mold steel. Compared with the traditional cumbersome process of disassembling, flipping, and re-clamping, it can significantly reduce the clamping time, eliminate the positioning deviation caused by frequent clamping, ensure that different operators can achieve stable clamping and flipping, and improve the quenching uniformity and product quality.

[0015] 2. The mold steel is quenched by the quenching mechanism. After quenching, the water pump draws water from the box and cools it through the nozzle. The first and second limit rings are set. The second limit ring prevents the linkage rod from shifting left and right, ensuring that the first and second bevel gears are always meshed. The first limit ring restricts the movement of the rotating rod, maintaining the stable transmission between the first and second pulleys. The clamping plate is replaceable, thus adapting to mold steel of different shapes and reducing the clamping difficulties caused by special shapes. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1-4A quenching device for heat treatment of mold steel includes a housing 1. A quenching assembly and a cooling assembly are respectively arranged on the top and one side of the housing 1. Circular holes are opened on both sides of the housing 1, and rotating rods 2 are installed in each of the two circular holes. Clamping assemblies are installed at the ends of the two rotating rods 2 that are close to each other, and first pulleys 8 are fixedly sleeved at the ends of the two rotating rods 2 that are far apart. Two fixing plates 12 are fixedly installed on one side of the housing 1. Both fixing plates 12 have circular holes, and a common linkage rod 13 is installed in each of the two circular holes. Second pulleys 15 are fixedly sleeved at both ends of the linkage rod 13. A belt 16 is respectively arranged between the two second pulleys 15 and the two first pulleys 8. A driving assembly is arranged below the linkage rod 13. The driving assembly includes a side plate 9 fixedly installed on one side of the housing 1, a motor 10 fixedly installed on the bottom side of the side plate 9, and the output end of the motor 10 rotating through the side plate 9 and fixedly connected to a first bevel gear 11. A second bevel gear is fixedly sleeved on the outer side of the linkage rod 13. 14. The second bevel gear 14 meshes with the first bevel gear 11. A motor 10 is provided. When the other side of the mold steel needs to be quenched, the motor 10 is started to drive the first bevel gear 11 to rotate. Because the first bevel gear 11 meshes with the second bevel gear 14, the second bevel gear 14 will synchronously drive the linkage rod 13 to rotate under the transmission of the first bevel gear 11. Since the two ends of the linkage rod 13 are fixedly sleeved with second pulleys 15, and belts 16 are provided between the two second pulleys 15 and the two first pulleys 8, the two first pulleys 8 will synchronously drive the rotating rod 2 fixedly connected to them to rotate under the transmission of the belts 16, thereby completing the flipping process of the mold steel. By flipping the mold steel without disassembling the fixture, the work efficiency of the clamping and quenching process is greatly improved, repeated clamping is avoided, clamping errors are reduced, and the stability of the mold steel during the flipping process is ensured, making the connection between the two-sided quenching processes smoother.

[0023] Specifically, the quenching assembly includes a bracket 21 fixedly installed on the top side of the housing 1. The bracket 21 is U-shaped, and a quenching mechanism 22 is provided on the bottom side of the bracket 21. With the quenching mechanism 22 provided, when the mold steel is clamped by two clamping plates 7, the quenching mechanism 22 can be activated to quench the surface of the mold steel.

[0024] Specifically, the cooling assembly includes a water pump 17 fixedly installed on one side of the housing 1, an extraction pipe 18 fixedly connected to the bottom of the water pump 17, the other end of the extraction pipe 18 extending into the housing 1, a delivery pipe 19 fixedly connected to the top of the water pump 17, the other end of the delivery pipe 19 extending into the housing 1 and fixedly connected to a nozzle 20. By setting up the water pump 17, after one side of the mold steel is quenched, the water pump 17 is started to drive the extraction pipe 18 to extract water from the housing 1, and then the water is sprayed onto the mold steel through the nozzle 20 at the other end of the delivery pipe 19, thereby achieving the cooling treatment of the mold steel.

[0025] Specifically, the clamping assembly includes two rotating rods 2, each with a connecting block 3 fixedly connected to its opposite face. Each connecting block 3 has a through hole, and an electric push rod 4 is fixedly installed on the inner wall of the side of each through hole closest to each other. The output ends of the two electric push rods 4 pass through the connecting block 3 and each has a threaded groove 5. Threaded posts 6 are threaded into each of the two threaded grooves 5. Clamping plates 7 are fixedly connected to the ends of the two threaded posts 6 closest to each other. The two clamping plates 7 are symmetrically arranged. When clamping mold steel, the mold steel to be quenched is placed between the two clamping plates 7, and then the two electric push rods 4 are started simultaneously to move the two clamping plates 7 towards both sides of the mold steel. As the electric push rods 4 continue to run, the two clamping plates 7 can complete the tight clamping of the mold steel. Because the two clamping plates 7 are threaded into the two threaded grooves 5 via the threaded posts 6, when clamping cylindrical mold steel, simply rotating the clamping plates 7 will disengage the two threaded posts 6 from the two threaded grooves 5, and then the arc-shaped clamping plates 7 can be replaced.

[0026] Specifically, two second limiting rings 24 are fixedly sleeved on the outer side of the linkage rod 13. The two second limiting rings 24, with their opposite sides, are respectively attached to the opposite sides of the two fixed plates 12. A set of first limiting rings 23 is fixedly sleeved on the outer side of each of the two rotating rods 2. There are two sets of first limiting rings 23 in each set. The opposite sides of the two sets of first limiting rings 23 are respectively attached to one side of the housing 1 and one side of its inner wall. By setting two second limiting rings 24, the two second limiting rings 24 can limit the linkage rod 13, so that it can only rotate and avoid left and right deviation, which would cause the second bevel gear 14 and the first bevel gear 11 to not mesh. By setting two sets of second limiting rings 24, the two sets of second limiting rings 24 can limit the rotation of the two rotating rods 2, so that they can only rotate, thereby ensuring the stable transmission between the two first pulleys 8 and the two second pulleys 15.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: Place the mold steel to be quenched between the two clamping plates 7, then simultaneously start the two electric push rods 4. The electric push rods 4 operate, pushing the two clamping plates 7 towards both sides of the mold steel. As the electric push rods 4 continue to operate, the two clamping plates 7 gradually approach and complete the clamping of the mold steel. After the mold steel is clamped, it is quenched by the quenching mechanism 22 under the bracket 21. When one side of the mold steel is quenched, start the water pump 17. The water pump 17 operates, driving the extraction pipe 18 to extract water from the box 1. The water is then sprayed onto the mold steel from the nozzle 20 at the other end of the delivery pipe 19, thereby achieving the cooling treatment of the mold steel. If it is necessary to further heat the mold... The other side of the steel is quenched. The motor 10 is started, and the motor 10 drives the first bevel gear 11 to rotate. Since the first bevel gear 11 meshes with the second bevel gear 14, under the transmission action of the first bevel gear 11, the second bevel gear 14 synchronously drives the linkage rod 13 to rotate. The two ends of the linkage rod 13 are fixedly sleeved with second pulleys 15. The two second pulleys 15 are respectively connected to the two first pulleys 8 through belts 16. Under the transmission of belts 16, the two first pulleys 8 synchronously drive the rotating rod 2 fixedly connected to them to rotate, thereby completing the flipping of the mold steel. After the mold steel is flipped, the quenching mechanism 22 can continue to quench the flipped surface.
