Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cemented carbide tool forging and casting, and particularly relates to a forging and casting device for cemented carbide tools. Background Technique
[0002] The forging and casting of cemented carbide tools is mainly achieved through powder metallurgy technology, covering multiple steps from material selection to the finished product out of the furnace. The main links include the preparation of tungsten carbide powder, mixing with metal binders, spray drying of powder materials, die pressing of workpieces, sintering, and possible coating treatments, etc. Each step has an important impact on the performance of the tool, determining its final hardness, toughness, and durability.
[0003] When forging and casting different types of cemented carbide tools, different-shaped molds need to be replaced. However, general forging and casting molds are not convenient to replace, and it takes a lot of time for workers to replace them, which not only increases the workload of workers but also reduces work efficiency, resulting in a decrease in production. Therefore, we propose a forging and casting device for cemented carbide tools. Content of the Utility Model
[0004] The purpose of the utility model is to provide a forging and casting device for cemented carbide tools. By starting the first motor, two sliders move in opposite directions to release the clamping and fixing of the mold, and then it can be directly removed and replaced. By rotating the second limiting plate upward, the lower pressing mold can be directly pulled out from the fixed block to complete the disassembly, solving the problem that general existing forging and casting molds are not convenient to replace, which requires workers to spend a lot of time to replace them, not only increasing the workload of workers but also reducing work efficiency, resulting in a decrease in production.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model relates to a forging device for cemented carbide cutting tools, which comprises a tabletop. Four corners of the bottom of the tabletop are fixedly connected with supporting legs. Four corners of the top of the tabletop are fixedly connected with supporting columns. The top of each of the four supporting columns is fixedly connected with a top plate. A first motor is in contact with the top of the tabletop. The left output end of the first motor is fixedly connected with a bidirectional threaded rod. A slider is threadedly connected to the outer surface of the bidirectional threaded rod. A mold is in contact with the left side of the slider. A fixing block is arranged above the mold. A sliding groove is formed in the front of the fixing block. A downward pressing mold is in contact with the inner wall of the sliding groove. A second limiting plate is in contact with the front of the downward pressing mold. By setting the second limiting plate, specifically, by starting the first motor, the two sliders move in opposite directions, releasing the clamping and fixing of the mold, and then it can be directly removed and replaced. By rotating the second limiting plate upward, the downward pressing mold can be directly pulled out from the fixing block, thus completing the disassembly. The staff can quickly disassemble the downward pressing mold and the mold, saving a lot of time for replacing the mold, improving work efficiency and reducing the workload of the staff.
[0007] Further, a fixing plate is fixedly connected to the top of the tabletop. A limiting groove is formed in the top of the fixing plate and is in contact with the bottom of the mold. A handle is fixedly connected to the back of the mold, and the handles are symmetrically arranged with the mold as the center. A first limiting plate is fixedly connected to the left side of the fixing plate, and the bottom of the first limiting plate is in contact with the top of the tabletop. The setting of the limiting groove makes it more convenient to place the mold, and at the same time plays a limiting role, making it more convenient for the device to replace the mold.
[0008] Further, a sliding groove is formed in the right side of the fixing plate. A fixing ring is fixedly connected to the bottom of the inner wall of the sliding groove and is in contact with the middle part of the bidirectional threaded rod. The inner wall of the sliding groove is in contact with the outer surface of the slider. The number of the sliders is two, and the two sliders are symmetrically arranged with the fixing ring as the center. The setting of the sliding groove makes the slider move more smoothly inside it, avoiding the phenomenon of dislocation.
[0009] Further, a fixing hole is formed in the top of the top plate. A hydraulic push rod is fixedly connected to the inner wall of the fixing hole. The bottom output end of the hydraulic push rod is fixedly connected with a push rod, and the bottom of the push rod is in contact with the top of the fixing block. The formation of the fixing hole can better fix the hydraulic push rod and make it operate more stably.
[0010] Further, the second limiting plate is rotatably connected to the fixing block through a pin shaft. A limiting groove is formed in the bottom of the second limiting plate. A limiting post is in contact with the inner wall of the limiting groove, and the back of the limiting post is fixedly connected to the front of the fixing block. The formation of the limiting groove enables it to be stuck on the limiting post to limit the downward pressing mold and make the device safer to use.
[0011] Further, one end of the top plate away from the hydraulic push rod is fixedly connected with a second motor. The output end of the second motor at the bottom is fixedly connected with a first rotating column. The bottom of the first rotating column is fixedly connected with a first gear. The left side of the first gear is meshed and connected with a second gear. The top of the second gear is fixedly connected with a second rotating column. The second rotating column is rotationally connected to the bottom of the top plate through a pin shaft. The bottom of the second gear is fixedly connected with a connecting block. A fan is arranged on the left side of the connecting block. In the present utility model, by arranging the connecting block, specifically, by starting the second motor, the first gear drives the connecting block fixed at the bottom of the second gear to rotate, and the rotation of the connecting block will drive the fan to move synchronously. Due to the arrangement of the fan, the powder remaining on the die after forging can be blown away in time, keeping the tabletop clean after forging, avoiding excessive powder residue, making the device more convenient to use, and eliminating the need for a large amount of manpower and time for cleaning.
[0012] The present utility model has the following beneficial effects:
[0013] 1. In the present utility model, by arranging the second limiting plate, specifically, by starting the first motor, the two sliders move in opposite directions, releasing the clamping and fixing of the die, and then it can be directly removed and replaced. By rotating the second limiting plate upward, the lower pressing die can be directly pulled out from the fixed block, completing the disassembly. The staff can quickly disassemble the lower pressing die and the die, saving a large amount of time for replacing the die, improving work efficiency, and reducing the workload of the staff.
