Description

Technical Field

[0001] The utility model relates to the technical field of gradient hard alloy processing, in particular to a partition device for gradient hard alloy. Background Art

[0002] As a tool material, cemented carbide has been widely used in various cutting tools, mining tools and wear-resistant and corrosion-resistant parts due to its high hardness, high strength, high elastic modulus, wear resistance and corrosion resistance. In order to adapt to various service conditions and improve efficiency, people have developed materials such as gradient cemented carbide and ultrafine cemented carbide to address the contradiction between high hardness and low toughness of traditional cemented carbide.

[0003] According to the partition device for gradient cemented carbide disclosed in Chinese patent publication number CN216421061 U, the patent can effectively realize one-time pressing and forming of different components of the core and surface layer, which is conducive to obtaining high-performance gradient cemented carbide at low cost.

[0004] However, this patent still has certain shortcomings in actual use. Since the partition is moved out of the mold through the linkage between the first connecting rod, the second connecting rod and the third connecting rod, and the driving power is provided by the first hydraulic cylinder and the second hydraulic cylinder, the partition does not move straight upward when it is moved out due to the limitation of the connecting rod structure. Due to the gravity pressing of the metal powder, a large burden will be placed on the structure during the inclined movement, which is not conducive to long-term stable use. At the same time, the partition is still located above the mold after being moved out of the mold, which will cause certain restrictions on the subsequent pressing work and cannot meet the pressing requirements of the material inside the mold at one time. In this regard, the present application provides a partition device for gradient cemented carbide to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 3 The utility model provides a technical solution: a partition device for gradient cemented carbide, comprising a base 1, a linear component 200 is installed on the top of the base 1, a lifting component 300 is installed on the top of the linear component 200, and the main mold 4 with an open top is fixedly installed on the top of the base 1; through the coordinated use of the linear component 200, the lifting component 300 and the main mold 4 on the top of the base 1, the partition structure can be reasonably removed from the mold and will not be located above the mold, so that the top of the mold can be in a completely empty state, which is convenient for the subsequent pressing structure on the top to perform one-time pressing work, indirectly improving the processing efficiency of the gradient cemented carbide, thereby effectively improving the practicality of the partition device for gradient cemented carbide.

[0028] In this embodiment, the lifting assembly 300 is a structure used to easily remove the partition structure from the mold.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, the lifting assembly 300 includes two lifting cylinders 301, a second servo motor 302 fixedly installed on the outside of the lifting cylinder 301, two rotating rods 303 rotatably connected to the inside of the lifting cylinder 301 through bearings, a sprocket 304 fixedly installed on the outside of the rotating rod 303, a chain 305 meshing and transmission-connected between the outsides of the two corresponding sprockets 304, a support plate 306 fixedly installed on the side of the chain 305 close to the main mold 4, a linear guide rail 307 fixedly installed between the inner bottom wall and the inner top wall of the lifting cylinder 301, a fixed plate 308 fixed on the outside of the support plate 306, an arc-shaped partition 309 fixed on the outside of the fixed plate 308, a worm wheel 310 fixedly installed on the outside of the bottom rotating rod 303, and a worm 311 rotatably connected to the inside of the lifting cylinder 301 through bearings.

[0030] It should be noted that a rubber pad 5 is bonded to the bottom of the support plate 306, and the bottom of the rubber pad 5 can abut against the top of the main mold 4, so that the rubber pad 5 can play the role of elastic abutment to avoid direct collision and contact between the structures. The corresponding two rotating rods 303 are located on the same vertical line, so that the corresponding two sprockets 304 can drive the chain 305 for stable transmission. A guide rail hole is opened on the top of the support plate 306 for the corresponding linear guide rail 307 to pass through and slide on the outside, so that the support plate 306 can slide linearly on the outside of the linear guide rail 307 under the restriction of the guide rail hole.

[0031] In addition, the two fixing plates 308 are respectively located on the opposite side of the two support plates 306, and the opposite sides of the two arc-shaped partitions 309 can fit together. The top of the arc-shaped partition 309 is arc-shaped, so that the two arc-shaped partitions 309 can be combined into a cylindrical tube-shaped structure with openings at the top and bottom, and the arc-shaped setting of the top makes it easier to move out from the inside of the main mold 4.

[0032] At the same time, the opposite ends of the two worms 311 are rotatably connected to the opposite sides of the two linear guide rails 307 through bearings, and the outer sides of the worms 311 and the outer sides of the corresponding worm wheels 310 are meshed with each other. The output shaft of the second servo motor 302 passes through the outer side of the corresponding lifting cylinder 301 and is fixedly connected to the end of the corresponding worm 311, so that the second servo motor 302 can drive the worm 311 to rotate stably, and can drive the corresponding worm wheel 310 to rotate under the action of meshing.

[0033] In this embodiment, the linear assembly 200 is a structure used to move the lifting assembly 300 away from the outside of the main mold 4.

[0034] like Figure 1 As shown, the linear assembly 200 includes two movable grooves 201 opened on the top of the base 1, a screw rod 202 rotatably connected to the inner side of the movable groove 201 through a bearing, a movable block 203 threadedly connected to the outer side of the screw rod 202, a first servo motor 204 fixedly installed on the outer side of the base 1, and a linear guide rail 205 fixedly installed on the inner bottom wall of the movable groove 201.

[0035] It should be noted that the lifting cylinder 301 is fixed to the top of the corresponding moving block 203, and the opposite sides of the two lifting cylinders 301 are open, so that the lifting cylinder 301 can move synchronously with the corresponding moving block 203. The bottom of the moving block 203 is provided with a slide rail groove for plugging and sliding relative to the outside of the linear slide rail 205, and the left and right sides of the slide rail groove are open, so that the moving block 203 can slide linearly under the restriction and guidance of the corresponding linear slide rail 205.

[0036] In addition, the output shafts of the two first servo motors 204 respectively pass through the left and right sides of the base 1 and are fixedly connected to the opposite ends of the two screw rods 202, so that the first servo motors 204 can drive the corresponding screw rods 202 to rotate.

[0037] The working principle of the above embodiment is:

[0038] When processing the gradient cemented carbide, the two arc-shaped partitions 309 are located inside the main mold 4, and the opposite sides of the two arc-shaped partitions 309 are fitted together to form a cylindrical space. The metal powder is fed into the interior of the main mold 4, and the metal powder at the bottom of the main mold 4 and the outside of the arc-shaped partition 309 are the same, while the material inside the arc-shaped partition 309 is made of other metal powders, so that the composition of the surface layer and the core layer of the gradient cemented carbide are inconsistent. The second servo motor 302 is started to drive the corresponding worm 311 to rotate, so that the worm wheel 310 rotates and drives the corresponding rotating rod 303 to rotate, and then the sprocket 304 and the chain are rotated. Under the coordinated transmission action between 305, the support plate 306 is driven to slide up and down on the outside of the corresponding linear guide rail 307, so that the fixed plate 308 can drive the arc partition 309 to move out from the inside of the main mold 4 and move it to the top of the main mold 4, start the first servo motor 204, drive the screw rod 202 to rotate, and under the guidance and limiting action of the linear slide rail 205, the moving block 203 can drive the lifting cylinder 301 to move left and right in a straight line, so that the arc partition 309 can be moved away from the main mold 4, so that there is an open space above the main mold 4, and finally the mixed metal powder inside the main mold 4 can be pressed and formed at one time through the pressing equipment.

[0039] Compared with the existing technology, the partition device for gradient cemented carbide, through the coordinated use of the linear component 200, the lifting component 300 and the main mold 4 on the top of the base 1, can reasonably remove the partition structure completely from the mold, and prevent it from being located above the mold, so that the top of the mold can be in a completely empty state, which is convenient for the subsequent one-time pressing work of the top pressing structure, indirectly improving the processing efficiency of the gradient cemented carbide, thereby effectively improving the practicality of the partition device for gradient cemented carbide, and solving the problem that the partition structure of the existing partition device for gradient cemented carbide is not easy to remove during use and is still located above the mold, affecting the efficient subsequent pressing work.
