Description

Technical Field

[0001] The utility model relates to the technical field of stamping technology, in particular to a stamping device capable of rapid cooling for mechanical design and manufacturing. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. It is an indispensable part of the manufacturing of parts for modern mechanical design.

[0003] Cold stamping is a method of forming sheet metal or hot material by applying pressure to it on a press machine using a stamping die at room temperature. In order to facilitate material unloading, existing stamping devices usually have an ejection structure, or allow the formed workpiece to move up with the stamping head, and then the workpiece falls from the stamping head into the chute to complete the unloading. Some raw materials are heated to increase their plasticity before stamping, resulting in heat remaining in the workpiece after stamping, which makes it difficult for workers to remove the workpiece and they are easily burned or affected by the emitted heat. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a stamping device that can be quickly cooled for mechanical design and manufacturing to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping device with rapid cooling for mechanical design and manufacturing, comprising a device main body, support frames are connected to both sides of the top of the device main body, and second hydraulic cylinders are installed on the top of the two support frames, and the output ends of the two second hydraulic cylinders are connected to stamping dies through piston rods, a water baffle is connected to the upper part of the inside of the device main body through a torsion spring shaft, a damper is installed at the lower part of the inside of the device main body, and a spring and a folding sleeve are sleeved on the outside of the damper, and a buffer pad is connected to the top of the damper through a support plate.

[0006] By adopting the above technical scheme, the two second hydraulic cylinders are used to push the two stamping dies to close so as to facilitate the stamping and forming process. At the same time, the grooves and protrusions on one side of the two stamping dies are inlaid to form a connection, so as to facilitate the pressure distribution of the two stamping dies. At the same time, the stamping dies are supported by the support frame, and the structural strength is increased in conjunction with the support frame and the multiple ribs on the stamping die, which effectively avoids the pressure separation and bending of the two stamping dies when the punching head moves downward to apply pressure to stamp the workpiece. After stamping and forming, the two hydraulic cylinders pull the two stamping dies apart. At this time, the formed workpiece falls into the main body of the device due to gravity and contacts with water, coolant or cooling oil, thereby cooling the workpiece.

[0007] Furthermore, a material taking door is connected above the outer surface of the device body.

[0008] By adopting the above technical solution, the workpiece falls on the top of the buffer pad and contacts with water, coolant or cooling oil, so that the workpiece is cooled down, and then the staff can open the material removal door to take the workpiece out of the device body.

[0009] Furthermore, the stamping dies are slidably connected to the device body and the support frame respectively, and grooves and protrusions are provided on one side of the two stamping dies.

[0010] By adopting the above technical solution, the two second hydraulic cylinders push the two stamping dies to close to facilitate the stamping process. At the same time, the grooves and protrusions on one side of the two stamping dies are inlaid to form a connection, which makes it easy to share the pressure on the two stamping dies.

[0011] Furthermore, a plurality of ribs are provided on the top of the stamping die, the top of the support frame, the outer surface of the support frame and the back of the support frame.

[0012] By adopting the above technical solution, the stamping die is supported by a support frame, and the structural strength is increased by cooperating with multiple ribs on the support frame and the stamping die, thereby effectively preventing the two stamping dies from being separated and bent under pressure when the punching head moves downward to apply pressure to stamp the workpiece.

[0013] Furthermore, two of the water baffle plates and torsion spring shafts are provided, and the water baffle plates are rotatably connected to the device body.

[0014] By adopting the above technical solution, when the workpiece falls under the influence of gravity, the water baffle is knocked open by the workpiece, rotates downward and compresses the torsion spring shaft. When the workpiece falls into water, coolant or cooling oil and is cooled, the torsion spring shaft drives the baffle to reset and close the device body, preventing the workpiece from splashing water onto the top of the device body and causing dirt.

[0015] Furthermore, the buffer pad is made of high temperature resistant graphite packing, and the support plate is made of aluminum alloy material.

[0016] By adopting the above technical solution, the workpiece falls on the top of the buffer pad and contacts with water, coolant or cooling oil, so that the workpiece is cooled down. Since the buffer pad is made of flexible material, the impact force is reduced.

[0017] Furthermore, a plurality of through holes are provided on both sides of the top of the support plate.

[0018] By adopting the above technical solution, the buffer pad can be supported by the support plate, and the through holes opened on both sides of the top of the support plate are convenient for cooling flow, thereby avoiding that the displacement of the support plate is affected.

[0019] Furthermore, four of the dampers, springs and folding sleeves are provided, and the four dampers, springs and folding sleeves are distributed in a rectangular array.

[0020] By adopting the above technical solution, the damper and spring are compressed to absorb and consume the impact force, thereby effectively avoiding damage to the workpiece caused by falling, and the folding sleeve prevents water, coolant or cooling oil in the device body from adhering to the surface of the damper and spring.

[0021] Furthermore, a top frame is connected to the top of the device body, and a first hydraulic cylinder is installed on the top of the top frame, and an output end of the first hydraulic cylinder is connected to a punching head through a piston rod.

[0022] By adopting the above technical solution, the staff places the raw material to be stamped on the top of the stamping die and starts the first hydraulic cylinder. After the first hydraulic cylinder is started, the output end drives the stamping head downward through the piston rod. After the stamping head moves downward, pressure is applied to the raw material so that the raw material is pressed into the stamping die. At this time, the raw material is stamped into a workpiece through the cooperation of the stamping head and the stamping die.

[0023] Furthermore, semiconductor coolers and fans are installed on both sides of the interior of the device body, and dustproof nets are installed on both sides of the outer surface of the device body and both sides of the back.

[0024] By adopting the above technical solution, while water, coolant or cooling oil is cooling the workpiece, the heat in the cooling fluid is absorbed by the semiconductor refrigerator to reduce the temperature of the cooling fluid, thereby avoiding long-term use that causes the fluid temperature to rise and make it impossible to cool the workpiece. Afterwards, the fan generates airflow to take away the heat of the semiconductor refrigerator so that it can continue to cool the cooling fluid, while the dust entry is reduced through the dustproof net.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model is provided with a support frame, a second hydraulic cylinder and a stamping die. The two second hydraulic cylinders push the two stamping dies to close so as to facilitate stamping and forming processing. At the same time, the grooves and protrusions on one side of the two stamping dies are inlaid to form a connection, which is convenient for sharing the pressure on the two stamping dies. At the same time, the stamping dies are supported by the support frame, and the structural strength is increased in conjunction with the support frame and the multiple ribs on the stamping die, which effectively prevents the two stamping dies from being separated and bent under pressure when the punching head moves downward to apply pressure to stamp the workpiece. After stamping and forming, the two hydraulic cylinders pull the two stamping dies apart. At this time, the formed workpiece falls into the main body of the device under the influence of gravity and contacts with water, coolant or cooling oil, thereby cooling the workpiece; both the unloading is completed and the staff is prevented from being scalded when taking the material;

[0027] 2. The utility model provides a water baffle and a torsion spring shaft. When the workpiece falls under the influence of gravity, the water baffle is knocked open by the workpiece, rotates downward and compresses the torsion spring shaft. When the workpiece falls into water, coolant or cooling oil and is cooled, the torsion spring shaft drives the baffle to reset and close the device body, so as to prevent the workpiece from splashing water to the top of the device body and causing dirt; it effectively prevents water splashing;

[0028] 3. The utility model adopts the arrangement of a damper, a spring, a folding sleeve, a support plate and a buffer pad. When a workpiece falls into water, coolant or cooling oil and is cooled, it falls on the top of the buffer pad. The buffer pad is made of flexible material to reduce the impact force. At the same time, the damper and the spring are compressed to absorb and consume the impact force, effectively avoiding the workpiece from being damaged by the fall. At the same time, the folding sleeve prevents the water, coolant or cooling oil in the device body from adhering to the surface of the damper and the spring, so that the workpiece can be buffered to avoid being damaged by the fall.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A stamping device capable of rapid cooling for mechanical design and manufacture, such as Figure 1-Figure 4As shown, it includes a device body 1, support frames 5 are connected to both sides of the top of the device body 1, and second hydraulic cylinders 6 are installed on the tops of the two support frames 5. The output ends of the two second hydraulic cylinders 6 are connected to stamping dies 7 through piston rods. The stamping dies 7 are slidably connected to the device body 1 and the support frame 5 respectively. After the two second hydraulic cylinders 6 are closed, the two stamping dies 7 are pulled apart. At this time, the formed workpiece is separated from the stamping die 7, and then the workpiece falls under the influence of gravity to complete the unloading; grooves and protrusions are provided on one side of the two stamping dies 7, and multiple ribs are provided on the top of the stamping die 7, the top of the support frame 5, the outer surface of the support frame 5 and the back of the support frame 5. The stamping die 7 is supported by the support frame 5, and the structural strength is increased in conjunction with the multiple ribs on the support frame 5 and the stamping die 7, which effectively prevents the two stamping dies 7 from being separated and bent under pressure when the punch head 4 moves downward to apply pressure to stamp the workpiece;

[0038] A water baffle plate 9 is connected to the upper part of the device body 1 through a torsion spring shaft 10. Two water baffle plates 9 and torsion spring shafts 10 are provided. The water baffle plate 9 is rotatably connected to the device body 1. When the workpiece falls under the influence of gravity, the water baffle plate 9 is knocked open by the workpiece and rotates downward and compresses the torsion spring shaft 10. When the workpiece passes through the baffle plate, the torsion spring shaft 10 drives the baffle plate to reset and close the device body 1 to prevent the workpiece from splashing water to the top of the device body 1 and causing dirt;

[0039] A damper 11 is installed at the lower part of the device body 1, and a spring 12 and a folding sleeve 13 are sleeved on the outside of the damper 11. A buffer pad 15 is connected to the top of the damper 11 through a support plate 14. The buffer pad 15 is made of high-temperature resistant graphite packing, and the support plate 14 is made of aluminum alloy. A plurality of through holes are opened on both sides of the top of the support plate 14. Four dampers 11, springs 12 and folding sleeves 13 are provided. The four dampers 11, springs 12 and folding sleeves 13 are distributed in a rectangular array. Since the buffer pad 15 is made of flexible material to reduce the impact force, the damper 11 and the spring 12 are compressed to absorb and consume the impact force, which effectively avoids the damage caused by the workpiece falling.

[0040] A material taking door 8 is connected to the upper part of the outer surface of the device body 1 , and the staff can open the material taking door 8 to take the workpiece out of the device body 1 .

[0041] See also Figure 1 and Figure 2 In the above embodiment, a top frame 2 is connected to the top of the device body 1, and a first hydraulic cylinder 3 is installed on the top of the top frame 2. The output end of the first hydraulic cylinder 3 is connected to the punch head 4 through a piston rod. After the first hydraulic cylinder 3 is started, the output end drives the punch head 4 to move downward through the piston rod. After the punch head 4 moves downward, pressure is applied to the raw material so that the raw material is pressed into the punching die 7. At this time, the punch head 4 cooperates with the punching die 7 to punch the raw material into a workpiece.

[0042] Embodiment 2:

[0043] On the basis of the above-mentioned embodiment 1, although by setting the support frame 5, the second hydraulic cylinder 6 and the stamping die 7, it is possible to complete the unloading and avoid the staff from being scalded when taking the materials; but after a period of use, the cooling fluid such as water, coolant or cooling oil will absorb more heat and cause the temperature to rise, thereby losing the effect of cooling the workpiece; now by setting the semiconductor refrigerator 16, the fan 17 and the dustproof net, it is possible to facilitate the cooling of the cooling fluid.

[0044] See also Figure 1 and Figure 2 In the above embodiment, semiconductor refrigerators 16 and fans 17 are installed on both sides of the device body 1. The semiconductor refrigerator 16 absorbs the heat in the cooling fluid to reduce the temperature of the cooling fluid, thereby preventing the fluid temperature from rising due to long-term use and making it impossible to cool the workpiece. After that, the fan 17 generates an airflow to take away the heat of the semiconductor refrigerator 16 so that it can continue to cool the cooling fluid. Dustproof nets 18 are installed on both sides of the outer surface of the device body 1 and both sides of the back to reduce the entry of dust.

[0045] The implementation principle of the utility model is as follows: first, the staff starts the second hydraulic cylinder 6. After the two second hydraulic cylinders 6 are started, the output end pushes the two stamping dies 7 to close through the piston rod. Then the staff places the raw material to be stamped on the top of the stamping die 7 and starts the first hydraulic cylinder 3. After the first hydraulic cylinder 3 is started, the output end drives the stamping head 4 to move downward through the piston rod. After the stamping head 4 moves downward, pressure is applied to the raw material so that the raw material is pressed into the stamping die 7. At this time, the stamping head 4 cooperates with the stamping die 7 to stamp the raw material into a workpiece;

[0046] At the same time, the grooves and protrusions on one side of the two stamping dies 7 are inlaid to form a connection, so that the pressure on the two stamping dies 7 is shared. At the same time, the stamping dies 7 are supported by the support frame 5, and the structural strength is increased by cooperating with the support frame 5 and the multiple ribs on the stamping die 7, which effectively prevents the two stamping dies 7 from being separated or bent under pressure when the punch head 4 moves downward to apply pressure to stamp the workpiece.

[0047] After the stamping is completed, the staff closes the first hydraulic cylinder 3 and the second hydraulic cylinder 6. After the first hydraulic cylinder 3 is closed, the punch head 4 is pulled back. After the two second hydraulic cylinders 6 are closed, the two stamping dies 7 are pulled apart. At this time, the formed workpiece is separated from the stamping die 7, and then the workpiece falls under the influence of gravity. When the workpiece falls under the influence of gravity, the water baffle 9 is knocked open by the workpiece and rotates downward and compresses the torsion spring shaft 10. When the workpiece passes the baffle, the torsion spring shaft 10 drives the baffle to reset and close the device body 1;

[0048] After that, the workpiece falls on the top of the buffer pad 15 and contacts with water, coolant or cooling oil, so that the workpiece is cooled down. At the same time, the water baffle 9 prevents the workpiece from splashing onto the top of the device body 1 and causing dirt. Since the buffer pad 15 is made of flexible material to reduce the impact force, the damper 11 and the spring 12 are compressed to absorb and consume the impact force, which effectively avoids the damage caused by the workpiece falling. The folding sleeve 13 prevents the water, coolant or cooling oil in the device body 1 from adhering to the surface of the damper 11 and the spring 12. Then the staff can open the material taking door 8 to take the workpiece out of the device body 1;

[0049] While the workpiece is being cooled by water, coolant or cooling oil, the heat in the cooling fluid is absorbed by the semiconductor refrigerator 16 to reduce the temperature of the cooling fluid, thereby preventing the fluid temperature from rising and becoming unable to cool the workpiece due to long-term use. Afterwards, the fan 17 generates an airflow to remove the heat of the semiconductor refrigerator 16 so that it can continue to cool the cooling fluid, while the dust entry is reduced by the dustproof net 18.

[0050] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
