Description

Technical Field

[0001] The invention belongs to the technical field of plate stamping and punching processing, and in particular relates to a stamping die for metal plate processing. Background Art

[0002] In the field of metal sheet processing, stamping dies are key process equipment for achieving sheet forming and processing, especially in the stamping and punching processing of aluminum or aluminum alloy sheets. Due to its advantages such as low density, high specific strength and good corrosion resistance, it is widely used in aerospace, automobile manufacturing, electronic equipment and other industries.

[0003] Since aluminum or aluminum alloy materials have high ductility and relatively low hardness, during the stamping process, the punch exerts huge pressure on the plate to separate it and form chips. During this process, the chips are very easy to deform. The deformed chips will be in close contact with the surface of the punching die in an irregular shape. At the same time, the surface of the aluminum alloy is relatively soft. When it comes into contact with the die surface, under the action of local high temperature and high pressure, the atoms of the two are easy to diffuse with each other, and then cold welding occurs, causing the chips to adhere firmly to the surface of the punching die.

[0004] Chips sticking to the punching die will have a great impact on product quality. On the one hand, when the upper die with chip adhesion is punched again, the adhered chips will form indentations and scratches on the surface of the sheet, and even cause local tearing of the sheet, which will seriously reduce the surface quality of the stamped parts and fail to meet the appearance requirements of the product. On the other hand, the presence of chips will change the working gap of the die, affect the stamping accuracy, cause deviations in the size of the stamped parts, and reduce the product qualification rate. In addition, the frequent occurrence of chip adhesion problems will increase the frequency of die cleaning, resulting in extended equipment downtime and a significant reduction in production efficiency. It will also accelerate die wear, increase die maintenance costs and replacement frequency. Summary of the Invention

[0005] The purpose of the present invention is to target an existing stamping die for metal plate processing. Its advantage is that the chips are easily adhered to the punching die when punching aluminum or aluminum alloy plates, which affects product quality, production efficiency and increases costs. The present invention innovatively sets a cleaning structure, which works in conjunction with the punching die component to effectively solve the above technical problems. The overall structural design is compact and reasonable. After a stamping is completed, the cleaning structure can automatically clean the chips adhered to the punching die to avoid damage to the plate surface caused by the chips, improve the surface quality and dimensional accuracy of the stamping parts, ensure the product qualification rate, and at the same time reduce the wear of the die, extend the service life of the die, and reduce the maintenance and replacement costs of the die, with significant economic benefits and practical value.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A stamping die for metal sheet processing, comprising a mounting base, a punching lower die bolted to the top of the mounting base, a punching upper die provided on the top of the mounting base, a mounting seat bolted to the top of the punching upper die, a movable seat bolted to the top of the mounting seat, and a cleaning structure provided between the punching upper die and the lower punching lower die;

[0007] The cleaning structure includes two pillars, which are bolted to both sides of the top of the mounting base, and a support plate is sleeved between the surfaces of the two pillars. Closed cavities are slidably provided on both sides of the bottom of the support plate, and pushing components are slidably provided on both sides of the top of the support plate, and the pushing components are used in conjunction with the closed cavity. The closed cavity is sleeved on the bottom end of the punching upper die, and a cleaning component is bolted to the top inside the closed cavity. The cleaning component is used in conjunction with the punching upper die, and a liquid collecting cover is bolted to the bottom of the closed cavity, and a spray pipe is bolted to the bottom of the inner wall of the closed cavity.

[0008] By adopting the above technical solution and setting up a cleaning structure, the automatic cleaning of the punching upper die is realized through the coordinated cooperation of components such as pillars, support plates, closing chambers, pushing components, liquid collecting hoods and spray pipes. After the stamping is completed, the closing chamber can wrap the punching upper die in time under the action of the pushing component, and the chips on the mold surface are cleaned by the cleaning component. At the same time, the spray pipe can spray and clean the mold surface, and the liquid collecting hood collects and discharges the cleaned chips and cleaning liquid, forming a complete cleaning process. This structure does not require frequent manual intervention, and can efficiently and automatically clean the chips on the mold surface, effectively prevent chips from sticking, improve the cleanliness and service life of the mold, and ensure the continuity and stability of the stamping process.

[0009] The present invention is further configured as follows: the pushing assembly includes a sliding oblique block and a fixed oblique block, the sliding oblique block is slidably arranged on both sides of the top of the support plate, and the bottom of the sliding oblique block is bolted with a connecting plate, the lower end of the connecting plate is at the bottom of the support plate, and the other end of the connecting plate is bolted to the closed cavity, two first return springs are provided on the side of the connecting plate close to the inner wall of the support plate, and the first return spring is connected to the side close to the inner wall of the support plate, the top of the fixed oblique block is bolted with a bracket, and the side of the bracket close to the mounting seat is bolted to it.

[0010] By adopting the above technical solution, a pushing component is set up. When the movable seat drives the punching upper die to move downward, the fixed bevel block moves downward together with the mounting seat. The inclined surface matching part of the fixed bevel block interacts with the inclined surface matching part of the sliding bevel block to push the sliding bevel block to slide on the top of the support plate. The sliding bevel block drives the two closed cavities to move in opposite directions through the connecting plate, so that the closed cavity can be moved out of the moving path of the punching upper die; when the punching upper die rises after the punching is completed, the first reset spring restores the deformation, pushing the sliding bevel block and the connecting plate to reset, so that the closed cavity returns to its initial position, and the pushing component realizes automatic pushing and resetting of the closed cavity. By utilizing the principle of inclined surface matching and spring reset, the action is reliable, and the movement of the closed cavity can be accurately controlled, ensuring that the cleaning structure cleans the mold at the right time, thereby improving the automation degree and working stability of the cleaning structure.

[0011] The present invention is further configured as follows: the sliding bevel block and the fixed bevel block are each provided with a bevel mating portion on the opposite side thereof, and the two are used in conjunction with the bevel mating portion; both sides of the support plate are provided with a clearance hole for use in conjunction with the fixed bevel block, and the clearance hole is located at the bottom of the sliding bevel block.

[0012] By adopting the above technical solution, the smooth operation of the pushing assembly is ensured through the inclined surface matching design of the sliding inclined block and the fixed inclined block and the setting of the clearance hole, so that the sliding inclined block can slide accurately on the support plate, thereby achieving stable pushing and resetting of the closed cavity, and improving the working accuracy and reliability of the pushing assembly.

[0013] The present invention is further configured as follows: the cleaning assembly includes two fixed shells, the fixed shells are bolted to the tops of the two closed cavities, and the interior of the fixed shells is bolted with a gear ring, the front side of the left gear ring is meshed and connected with a rotating gear, the top of the rotating gear is bolted with a connecting shaft, and the surface of the connecting shaft is sleeved with a synchronization plate, the rear side of the synchronization plate extends to the outside of the left fixed shell and is bolted with a mounting frame, the interior of the mounting frame is rotatably connected to two rollers, the surface of the roller is annularly bolted with a brush plate, and the brush plate is in contact with the side close to the punching upper mold, the surface of the roller is sleeved with two contact wheels, and the surface of the contact wheel is in contact with the surface of the punching upper mold.

[0014] The above technical solution is adopted, by setting up a cleaning component, when the two closed cavities are closed, the left ring gear can be engaged with the rotating gear, and as the rotating gear rotates, the connecting shaft and the synchronization plate can be synchronously driven to rotate along the path of the ring gear. The synchronization plate drives the roller to move through the mounting frame, and the brush plate on the roller contacts the surface of the punching upper die to brush the chips on the die surface. At the same time, the contact wheel rolls on the die surface, and drives the roller and the brush plate to rotate under the action of friction, and assists the brush plate to clean the chips and clean up the stuck chips. The cleaning component realizes automatic cleaning of the chips on the surface of the punching upper die. The cooperation of the brush plate and the contact wheel can clean the chips on the die surface in an all-round and effective manner, improves the cleaning efficiency and quality, reduces the workload of manual cleaning, ensures the cleanliness of the die, and thus improves the quality of the stamping products.

[0015] The present invention is further configured as follows: guide grooves are provided on the front and rear sides of the right side of the left gear ring, and positioning rods are provided on the front and rear sides of the left side of the right gear ring. The positioning rods are used in conjunction with the guide grooves, and the right end of the guide grooves is conically configured.

[0016] By adopting the above technical solution, the design of the guide groove and the positioning rod ensures the stability and accuracy of the two gear rings when they are spliced and aligned, so that the cleaning component can work smoothly and reliably, thereby improving the working reliability and service life of the cleaning component.

[0017] The present invention is further configured as follows: a U-shaped sealing member is provided on the right side of the left closed cavity, and a sealing groove for use with the sealing member is provided on the left side of the right closed cavity.

[0018] By adopting the above technical solution, the sealing of the closed chamber during the cleaning process is ensured by setting the seal and the sealing groove, preventing the leakage of cleaning liquid and chips. On the one hand, it avoids the pollution of the working environment, and on the other hand, it ensures that the liquid collection cover can effectively collect waste liquid and chips, thereby improving the working efficiency and cleaning effect of the cleaning structure.

[0019] The present invention is further configured as follows: a protective shell is bolted to the front and rear sides of the left liquid collecting hood, and a movable plate is slidably provided inside the protective shell, a moving contact and a static contact are respectively bolted between the movable plate and the inner wall of the protective shell, and the moving contact and the static contact are used in conjunction with each other, and a pushing member is bolted to the front and rear sides of the right liquid collecting hood, and the pushing member is used in conjunction with the movable plate.

[0020] By adopting the above technical solution, when the two closed cavities are aligned and connected, as the closed cavity and the liquid collecting cover gradually approach each other, the pushing member will push the movable plate to move inside the protective shell until the moving contact and the static contact trigger the signal that the closing of the closed cavity is completed. The signal can then be sent to the external main control device, which can control the cleaning assembly and other components to clean the punching hole upper die, thereby realizing automatic cleaning of the punching hole upper die.

[0021] The present invention is further configured as follows: a slide rod is passed through the front and rear sides of the movable plate, and a second return spring is sleeved on the left side of the slide rod surface, and the second return spring is connected to the movable plate and the inner wall of the protective shell on one side thereof.

[0023] The present invention is further configured as follows: opposite sides of the two liquid collecting covers are connected with discharge pipes, and the discharge pipes are externally connected to the liquid pump structure; a plurality of connecting holes are opened at the bottom of the closed cavity, and the connecting holes are connected to the liquid collecting covers.

[0024] By adopting the above technical solution, a complete waste liquid and chip discharge system is formed through the design of connecting holes, liquid collecting hoods and discharge pipes, which can discharge the waste liquid and chips generated during the cleaning process out of the equipment in time, keep the inside of the cleaning structure clean, prevent the accumulation of waste liquid and chips from affecting the cleaning effect and the normal operation of the equipment, and improve the working efficiency of the cleaning structure and the service life of the equipment.

[0025] The present invention is further configured as follows: guide rods are bolted at the four corners of the top of the mounting base, and the top of the guide rods extends to the top of the movable seat, a buffer spring is sleeved on the surface of the guide rods, and the top and bottom of the buffer spring are respectively connected to the movable seat and the mounting base.

[0026] By adopting the above technical solution, the stability and reliability of the stamping die are improved through the setting of guide rods and buffer springs. The guide rods ensure the movement accuracy of the upper die. The buffer springs can effectively absorb the impact force during the stamping process, reduce the vibration and wear of the equipment, extend the service life of the die and equipment, and also improve the quality of the stamping products.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. By setting up a pushing component, precise pushing and reset control of the closed cavity is achieved. During the stamping process, when the moving seat drives the punching upper die to move downward, the fixed inclined block and the inclined surface matching part of the sliding inclined block interact with each other to push the sliding inclined block and the connecting plate to move, thereby driving the closed cavity to expand and move it out of the downward movement path of the punching upper die; when the stamping is completed and the upper die rises, the sliding inclined block and the closed cavity are reset under the action of the first reset spring, and the stamping upper die is cleaned. This component ensures the normal operation of the cleaning structure and improves the automation and work efficiency of the cleaning structure;

[0051] Brief description of the usage process: When processing a metal sheet, place the metal sheet on the punching lower die 2. As the stamping equipment starts, the moving seat 5 drives the mounting seat 4 and the punching upper die 3 to move downward. During this process, the fixed bevel 642 moves downward together with the mounting seat 4. Due to the interaction between the inclined surface matching parts on the opposite sides of the fixed bevel 642 and the sliding bevel 641, the fixed bevel 642 pushes the sliding bevel 641 to slide on the top of the support plate 62. The sliding bevel 641 drives the two closed cavities 63 to move in the opposite direction through the connecting plate 643, so that the closed cavity 63 moves out of the moving path of the punching upper die 3 to avoid obstructing the punching of the punching upper die 3. Under pressure, the punching upper die 3 cooperates smoothly with the punching lower die 2 to complete the punching work on the metal sheet; after the punching is completed, the punching upper die 3 starts to rise under the drive of the stamping equipment, and at this time the first return spring 644 recovers its deformation, pushing the sliding bevel 641 and the connecting plate 643 to reset, driving the closing cavity 63 back to its initial position, so that it is sleeved on the bottom end of the punching upper die 3. As the two closing cavities 63 gradually approach, the pushing member 15 in the right liquid collecting cover 66 pushes the moving plate 12 to slide inside the protective shell 11 until the moving contact 13 on the moving plate 12 contacts the static contact 14 on the inner wall of the protective shell 11, triggering the closing cavity 63 is closed and the signal is sent to the external main control device. The main control device controls the cleaning component 65 and other components to clean the punching upper die 3. The left ring gear 652 is engaged with the rotating gear 653, and the rotating gear 653 is driven to rotate by the external driving device, thereby synchronously driving the connecting shaft 654 and the synchronous plate 655 to rotate along the path of the ring gear 652. The synchronous plate 655 drives the roller 657 to move through the mounting bracket 656. The brush plate 658 on the surface of the roller 657 contacts the surface of the punching upper die 3 to brush the chips on the surface of the die; at the same time, the contact wheel 65 on the surface of the roller 657 9 rolls on the mold surface, and drives the roller 657 and the brush plate 658 to rotate under the action of friction, and the auxiliary brush plate 658 cleans the chips and cleans up the stuck chips. During the cleaning process, the spray pipe 67 sprays and cleans the mold surface, and the cleaning liquid and the cleaned chips flow into the liquid collecting cover 66 through the connecting hole in the closed cavity 63. When the two liquid collecting covers 66 collect waste liquid and chips, the external liquid pump structure is started, and the waste liquid and chips in the liquid collecting cover 66 are discharged from the equipment through the discharge pipe 18, so as to keep the inside of the cleaning structure 6 clean. This cycle is repeated to realize continuous stamping processing of metal plates and automatic cleaning of molds.
