Description

Technical Field

[0001] The utility model relates to the technical field of mold production, in particular to a cold stamping forming device for metal mold production. Background Technique

[0002] A mold is a structure of various molds and parts used in industrial production to obtain required products by means of injection molding, blow molding, extrusion, die casting, smelting, stamping, etc. It is an important part of industrial production. There are many components in the mold. In addition to the originally milling-formed main body, there are water channels, guiding structures, buffer structures, blanking structures, etc. composed of various components. Some structures need to punch the sheet material into a specified shape or punch holes through a stamping structure during the production process.

[0003] In the existing cold stamping forming device for metal mold production, during operation, the stamping head for punching is exposed and located above the workpiece after stamping. Therefore, when the staff takes out the workpiece, the staff's arm is very easy to be scratched by the stamping head, resulting in the staff's arm being scratched painfully, and seriously, the skin may be scratched and damaged. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a cold stamping forming device for metal mold production to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A cold stamping forming device for metal mold production, including a device main body and a fixing plate. Both sides of the bottom of the fixing plate are connected with movable plates through limit guide rods, and a spring is connected between the fixing plate and the movable plates; an oil storage cavity is opened inside the movable plate, and a dust-proof plug is connected to the top of the oil storage cavity. Both sides of the bottom of the movable plate are fixed with baffle plates, and an oil suction sleeve is connected to the top of the baffle plates, and an oil suction rope is connected to one side of the oil suction sleeve.

[0006] By adopting the above technical scheme, under normal conditions, the stamping head is located inside the movable plate to prevent the staff from scratching the stamping head when blanking. During operation, the hydraulic cylinder drives the fixing plate to move downwards. At this time, due to the influence of the spring and gravity, the movable plate moves downwards to contact the sheet material, thereby limiting the sheet material to prevent the sheet material from shifting during stamping. As the fixing plate continues to move downwards, the fixing plate approaches the movable plate and compresses the spring. At the same time, the stamping head extends from the bottom of the movable plate to stamp the sheet material. After stamping, the hydraulic cylinder drives the fixing plate to move upwards, and the fixing plate pulls the movable plate to move upwards through the limit guide rods. At this time, the stamping head retracts into the movable plate; when the stamping head extends from the movable plate and retracts into the movable plate, the oil suction sleeve will apply lubricating oil on the surface of the stamping head to form an oil film, thereby reducing the wear between the stamping head and the sheet material and extending the service life of the stamping head.

[0007] Further, the cross-section of the limiting guide rod is in a "T" shape, and the limiting guide rod is slidably connected to the fixed plate.

[0008] By adopting the above technical solution, after stamping is completed, the hydraulic cylinder drives the fixed plate to move upward, and the fixed plate pulls the movable plate to move upward through the limiting guide rod. At this time, the stamping head retracts into the movable plate.

[0009] Further, a plurality of limiting guide rods are provided, and the plurality of limiting guide rods are distributed in a rectangular array.

[0010] By adopting the above technical solution, by increasing the number of limiting guide rods, the structural strength is increased, so as to increase the stability of the movable plate during up and down movement.

[0011] Further, the dust-proof plug is threadedly connected to the oil storage cavity.

[0012] By adopting the above technical solution, the staff removes the dust-proof plug, and then the staff injects lubricating oil into the oil storage cavity. The lubricating oil is stored through the oil storage cavity. After the oil injection is completed, the staff puts the dust-proof plug back.

[0013] Further, both the oil suction sleeve and the oil suction rope are made of oil-absorbing felt.

[0014] By adopting the above technical solution, the oil suction sleeve and the oil suction rope absorb the lubricating oil through the capillary effect, so that the lubricating oil enters the oil suction sleeve through the oil suction rope.

[0015] Further, two sets of the oil storage cavity, the baffle, the oil suction sleeve, the oil suction rope and the dust-proof plug are provided, and the two sets of the oil storage cavity, the baffle, the oil suction sleeve, the oil suction rope and the dust-proof plug are symmetrically distributed.

[0016] By adopting the above technical solution, the lubricating oil is stored through the oil storage cavity. At this time, the oil suction sleeve and the oil suction rope absorb the lubricating oil through the capillary effect, so that the lubricating oil enters the oil suction sleeve through the oil suction rope. When the stamping head extends from the movable plate and retracts into the movable plate, the oil suction sleeve will apply a lubricating oil film on the surface of the stamping head, thereby reducing the wear between the stamping head and the sheet material and extending the service life of the stamping head.

[0017] Further, a hydraulic cylinder is installed at the top of the device main body, and the fixed plate is connected to the bottom of the output end of the hydraulic cylinder. A stamping head is connected to the bottom of the fixed plate, and a stamping table is connected inside the device main body.

[0018] By adopting the above technical solution, the staff places the sheet material on the stamping table and then turns on the hydraulic cylinder. After the hydraulic cylinder starts, the output end drives the fixed plate to move downward, so that the stamping head stamps the sheet material.

[0019] Further, the stamping head is slidably connected to the oil suction sleeve.

[0020] By adopting the above technical solution, when the stamping head extends out of the movable plate and retracts into the movable plate, the oil suction sleeve will apply lubricating oil on the surface of the stamping head to form an oil film, thereby reducing the wear between the stamping head and the sheet material and prolonging the service life of the stamping head.

[0021] Furthermore, a communication groove is connected between the two oil storage cavities, and the communication groove is arc-shaped.

[0022] By adopting the above technical solution, the staff injects lubricating oil into the interior of the oil storage cavity, stores the lubricating oil through the oil storage cavity, and makes the two oil storage cavities communicate through the communication groove and replenishes the lubricating oil at the same time, simplifying the operation.

[0023] Furthermore, through holes are formed on the outer surface of the movable plate, and the oil storage cavity is communicated with the through holes. A window is fixed inside the through holes.

[0024] By adopting the above technical solution, the staff can check the lubricating oil level through the window, determine whether to stop oil injection, and facilitate subsequent determination of whether additional oil is needed.

[0025] To sum up, the main beneficial effects of the present utility model are as follows:

Through the settings of the fixed plate, movable plate, spring and limit guide rod in the present utility model, under normal conditions, the stamping head is located inside the movable plate, avoiding the stamping head being scratched by the staff during blanking. During work, the hydraulic cylinder drives the fixed plate to move downward. At this time, due to the influence of the spring and gravity, the movable plate moves downward to contact the sheet material, thereby limiting the sheet material to prevent the sheet material from shifting during stamping. As the fixed plate continues to move downward, the fixed plate approaches the movable plate and compresses the spring. At the same time, the stamping head extends out from the bottom of the movable plate to stamp the sheet material. After stamping is completed, the hydraulic cylinder drives the fixed plate to move upward, and the fixed plate pulls the movable plate upward through the limit guide rod. At this time, the stamping head retracts into the movable plate; it has good safety and avoids the stamping head being scratched by the staff during loading and unloading, and can clamp and limit the sheet material to prevent the sheet material from shifting;

[0027] 2. Through the settings of the oil storage cavity, baffle, oil suction sleeve, oil suction rope and dust-proof plug in the present utility model, the lubricating oil is stored through the oil storage cavity. At this time, the oil suction sleeve and the oil suction rope absorb the lubricating oil through capillary action, so that the lubricating oil enters the oil suction sleeve through the oil suction rope. When the stamping head extends out of the movable plate and retracts into the movable plate, the oil suction sleeve will apply lubricating oil on the surface of the stamping head to form an oil film, thereby reducing the wear between the stamping head and the sheet material and prolonging the service life of the stamping head; it is convenient to lubricate the stamping head to extend the service life of the structure.

At this time, the stamping head 8 retracts into the movable plate 5 to prevent the staff from scratching the stamping head 8 when blanking;

[0037] An oil storage cavity 9 is provided inside the movable plate 5. A dust-proof plug 13 is connected to the top of the oil storage cavity 9. The dust-proof plug 13 is threadedly connected to the oil storage cavity 9. Baffles 10 are fixed on both sides of the bottom of the movable plate 5. An oil suction sleeve 11 is connected to the top of the baffle 10. The stamping head 8 is slidably connected to the oil suction sleeve 11. An oil suction rope 12 is connected to one side of the oil suction sleeve 11. Both the oil suction sleeve 11 and the oil suction rope 12 are made of oil-absorbing felt. Two sets of the oil storage cavity 9, the baffle 10, the oil suction sleeve 11, the oil suction rope 12 and the dust-proof plug 13 are provided. The two sets of the oil storage cavity 9, the baffle 10, the oil suction sleeve 11, the oil suction rope 12 and the dust-proof plug 13 are symmetrically distributed. When the stamping head 8 extends from the movable plate 5 and retracts into the movable plate 5, the oil suction sleeve 11 will apply lubricating oil on the surface of the stamping head 8 to form an oil film, thereby reducing the wear between the stamping head 8 and the sheet material and extending the service life of the stamping head 8.

[0038] Refer to Figure 1 , Figure 2 and Figure 4 , in the above embodiment, a hydraulic cylinder 3 is installed on the top of the device main body 1. The fixed plate 4 is connected to the bottom of the output end of the hydraulic cylinder 3. The stamping head 8 is connected to the bottom of the fixed plate 4. The stamping table 2 is connected inside the device main body 1. During the stamping operation, the staff places the sheet material on the stamping table 2 and then turns on the hydraulic cylinder 3. After the hydraulic cylinder 3 starts, the output end drives the fixed plate 4 to move downward, so that the stamping head 8 stamps the sheet material.

[0039] Embodiment 2:

[0040] Based on the above Embodiment 1, it is time-consuming and laborious to separately inject oil into the two sets of oil storage cavities 9. Now, the following settings are made.

[0041] Refer to Figure 3 and Figure 4 , in the above embodiment, a communication groove 15 is connected between the two sets of oil storage cavities 9. The communication groove 15 is arc-shaped. The two sets of oil storage cavities 9 are communicated through the communication groove 15 to supplement lubricating oil at the same time, simplifying the operation; through holes are provided on the outer surface of the movable plate 5. The oil storage cavity 9 is communicated with the through holes. A viewing window 14 is fixed inside the through holes.

And the staff can view the lubricating oil level through the viewing window 14 to determine whether to stop injecting oil and to facilitate subsequent determination of whether additional oil needs to be added;

[0043] During the stamping operation, the staff puts the sheet material on the stamping table 2 and then turns on the hydraulic cylinder 3. After the hydraulic cylinder 3 is started, the output end drives the fixed plate 4 to move downward. At this time, the spring 6 and gravity affect the movable plate 5 to move downward and contact the sheet material, thereby limiting the sheet material to prevent it from shifting during stamping. As the fixed plate 4 continues to move downward, the fixed plate 4 approaches the movable plate 5 and compresses the spring 6. At the same time, the punch head 8 extends from the bottom of the movable plate 5 to punch the sheet material. After the stamping is completed, the hydraulic cylinder 3 drives the fixed plate 4 to move upward. The fixed plate 4 pulls the movable plate 5 upward through the limiting guide rod 7. At this time, the punch head 8 retracts into the movable plate 5 to prevent the staff from scraping the punch head 8 when cutting the material.

[0044] When the punch head 8 extends from the movable plate 5 or retracts into the movable plate 5 , the oil suction sleeve 11 will apply lubricating oil on the surface of the punch head 8 to form an oil film, thereby reducing the wear between the punch head 8 and the sheet material and extending the service life of the punch head 8 .
