Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, to a stamping die for automobile metal parts. Background Art

[0002] In the field of automobile manufacturing, automobile metal parts stamping dies play a vital role. With the rapid development of the automobile industry, consumers' requirements for automobile quality, performance and appearance are constantly increasing. As an important part of the automobile structure, the quality of automobile metal parts directly affects the overall performance and safety of the automobile. In the automobile production process, a large number of metal parts need to be manufactured through the stamping process. As the core tool of the stamping process, the design and manufacturing level of the stamping die directly determine the quality of the metal parts and production efficiency. Most existing automobile metal parts stamping dies are composed of a drive device, a fixed die and a movable die. During use, a metal sheet is placed on the upper outer surface of the fixed die. The drive device is then activated to drive the movable die to squeeze the metal sheet and form it on the fixed die. The drive device is then activated again to reset the movable die. At the same time, the metal part rises with the movable die. Although this type of die can complete the metal part stamping, when the movable die resets, the metal part can get stuck on the movable die surface. At this time, the staff needs to intervene to remove the metal part, which increases the staff's workload to a certain extent and reduces the working efficiency of the die. At the same time, there is a certain risk, which affects production safety. To address the shortcomings of the existing technology, we propose a metal part stamping die for automobiles. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a stamping die for automobile metal parts to solve the problem that metal parts are stuck on the surface of the movable die. At this time, staff intervention is required to remove the metal parts, which increases the workload of the staff to a certain extent, reduces the working efficiency of the mold, and also poses certain risks, affecting production safety.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a stamping die for automobile metal parts, comprising a die frame, wherein material taking assemblies are provided on both sides of the die frame, a material receiving assembly is provided on the lower side of the material taking assembly, a lower die is fixedly installed on the bottom of the upper side of the die frame, an upper die is provided above the lower die, a hydraulic telescopic rod is fixedly installed on the middle part of the upper outer surface of the upper die, and limit plates are fixedly installed on both sides of the hydraulic telescopic rod on the upper outer surface of the upper die, a limit rod is slidably installed on the upper inner wall of the die frame, and the outer wall of the limit rod is located on the upper outer surface of the die frame and is movably sleeved with a spring;

[0006] Among them, the hydraulic telescopic rod is fixedly installed on the upper inner wall of the mold frame, the lower end outer surface of the limit rod is fixedly installed on the upper outer surface of the upper mold, and the outer surface of one end of the spring 2 is fixedly installed on the inner cavity one end surface of the fixed block.

[0007] The gear train is mounted on a pair of gears, and the gears are mounted on two opposite sides of the gear frame, and the two gears are mounted on opposite sides of the gear frame. The gears are mounted on two opposite sides of the gear frame, and the two gears are mounted on opposite sides of the gear frame.

[0008] The lower edge of the inclined surface of the material taking block and the lower side surface of the upper mold are on the same vertical plane, so that the outer surface of one end of the material taking block can slide on the outer surface of one side of the upper mold and the limiting plate.

[0009] The width of the guide rail frame is greater than the width of the lower die and the upper die, and the width of the inclined plate is equal to the width of the lower die and the upper die.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model provides a material taking component, including a fixed block, which starts the hydraulic telescopic rod to drive the upper mold to move downward, so that the outer surface of one side of the upper mold slides downward along the inclined surface of the material taking block, thereby pushing the material taking block to drive the connecting column to slide on the inner wall of the fixed block, so that the connecting column squeezes the spring 2. After the stamping is completed, the hydraulic telescopic rod is started to drive the upper mold to rise and reset, and the inclined end of the material taking block is in contact with the outer surface of one side of the limit plate and slides until it slides on the outer surface of one side of the upper mold, removing the metal part from the outer surface of the upper mold. With the above structure, the material taking block is in contact with the outer surface of the upper mold and slides, which realizes the automatic removal of the metal part, avoids the danger caused by the intervention of the staff, reduces the labor, and thus improves the working efficiency of the mold;

[0012] The utility model provides a material receiving assembly, including a guide rail frame. When the upper mold moves downward, the gear column driven by the starting motor rotates. The rotation of the gear column drives the support plate to slide on the inner surface of the guide rail frame, so that the inclined plate leaves the bottom of the upper mold. When the mold rises after the stamping is completed, the motor is started to reverse. After the above process, the inclined plate is located under the upper mold. Then, the metal parts removed by the material taking assembly fall to the outer surface of the inclined plate and slide out of the mold frame for collection. Utilizing the above structure, the inclined plate and the support plate are driven to slide by the starting motor, thereby realizing the material receiving work of the mold, avoiding deformation or damage of the mold stamping parts, and greatly reducing the production cost of the metal parts.

[0022] The material-taking assembly 2 includes a fixed block 21, an outer surface of one side of the fixed block 21 is provided with a bolt hole 22, a connecting column 23 is slidably installed on the inner wall of the fixed block 21, a material-taking block 24 is fixedly installed on the outer surface of one end of the connecting column 23, and a spring 25 is fixedly installed on the outer surface of the other end of the connecting column 23.

[0023] Among them, the hydraulic telescopic rod 6 is fixedly mounted on the upper inner wall of the mold frame 1, the lower end outer surface of the limiting rod 8 is fixedly mounted on the upper outer surface of the upper mold 5, and the outer surface of one end of the spring 25 is fixedly mounted on one end surface of the inner cavity of the fixed block 21;

[0024] By starting the hydraulic telescopic rod 6 to drive the upper mold 5 to move downward, the outer surface of one side of the upper mold 5 slides downward along the inclined surface of the material removal block 24, thereby pushing the material removal block 24 to drive the connecting column 23 to slide on the inner wall of the fixed block 21, so that the connecting column 23 squeezes the spring 25. After the stamping is completed, the hydraulic telescopic rod 6 is started to drive the upper mold 5 to rise and reset. The inclined end of the material removal block 24 slides in contact with the outer surface of one side of the limit plate 7 until it slides on the outer surface of one side of the upper mold 5, removing the metal part from the outer surface of the upper mold 5, avoiding the danger caused by the intervention of the staff, thereby reducing their labor and improving the working efficiency of the mold.

[0025] The material receiving assembly 3 includes two guide rail frames 31, the inner surfaces of one end of the two guide rail frames 31 are rotatably connected to a gear column 32, the outer surface of one end of the gear column 32 is fixedly installed with a motor 33, the inner walls of the two guide rail frames 31 are slidably installed with a support plate 34, the upper outer surface of the support plate 34 is fixedly installed with an inclined plate 35, and the upper surfaces of both sides of the guide rail frames 31 are fixedly installed with racks 36. The two guide rail frames 31 are symmetrically fixedly installed on the inner surface of the mold frame 1, and the outer surfaces of both sides of the inclined plate 35 are attached between the opposite surfaces of the two guide rail frames 31. The motor 33 is fixedly installed on the outer surface of one side of the guide rail frame 31, and the rack 36 is meshed with the outer surface of the gear column 32.

[0026] The motor 33 drives the inclined plate 35 and the support plate 34 to slide, thereby realizing the material connection work of the mold, avoiding deformation or damage of the mold stamping parts, and greatly reducing the production cost of metal parts.

[0027] Among them, the lower edge of the inclined surface of the material removal block 24 is on the same vertical plane as the lower end side surface of the upper mold 5, so that the outer surface of one end of the material removal block 24 can slide on the outer surface of one side of the upper mold 5 and the limiting plate 7.

[0028] The width of the guide rail frame 31 is greater than the width of the lower mold 4 and the upper mold 5 , and the width of the inclined plate 35 is equal to the width of the lower mold 4 and the upper mold 5 .

[0029] The working process is as follows:

[0030] First, the mold is installed in a suitable working position, and then the metal sheet is placed on the upper outer surface of the lower mold 4. Then, the hydraulic telescopic rod 6 is started to drive the upper mold 5 to move downward, so that the outer surface of one side of the upper mold 5 slides downward along the inclined surface of the material-taking block 24, thereby pushing the material-taking block 24 to drive the connecting column 23 to slide on the inner wall of the fixed block 21, so that the connecting column 23 squeezes the spring 25, and at the same time, the gear column 32 driven by the motor 33 is rotated, and the rotation of the gear column 32 drives the support plate 34 to move on the inner surface of the guide rail frame 31. The surface slides, causing the inclined plate 35 to leave the bottom of the upper mold 5, completing the stamping. After the stamping is completed, the hydraulic telescopic rod 6 is started to drive the upper mold 5 to rise and reset, and the inclined end of the material taking block 24 is fitted on the outer surface of one side of the limit plate 7 and slides until it slides on the outer surface of one side of the upper mold 5, removing the metal part from the outer surface of the upper mold 5, and at the same time starting the motor 33 to reverse. After the above process, the inclined plate 35 is located directly below the upper mold 5, so that the removed metal part falls to the outer surface of the inclined plate 35 and slides out of the mold frame 1 for collection.
