Description

Technical Field

[0001] The utility model relates to the field of stamping and forming machines, in particular to a rapid stamping and forming device for a plastic cover plate. Background Art

[0002] Stamping refers to a processing method in which a press and a die are used to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. In traditional technology, a stamping machine generally drives the stamping action through a hydraulic mechanism, which makes the stamping speed slow. For batch product stamping, the stamping efficiency is slow, and the traditional stamping structure is complex and difficult to maintain. Therefore, it is necessary to design a fast stamping machine.

[0003] In the process of making plastic cover plates, the existing stamping forming machine cannot prevent the cooling of the plastic cover plate blank after hot melt softening and the cooling and shaping after stamping. Moreover, after stamping a plastic cover plate, the stamped cover plate needs to be removed from the stamping device. Therefore, its working efficiency is low and it also has certain risks.

[0004] For example, the Chinese invention patent (application number: CN201920214053.1) discloses a "rapid stamping and forming device for plastic cover plates".

[0038] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0039] Embodiment

[0040] Please refer to Figure 1 , a rapid stamping and forming device for plastic cover plates, which includes an installation component 10. The installation component 10 includes a base. A working group 11 is provided on the top of the base. A processing channel 12 is opened on one side of the working group 11. An installation plate 15 is provided at the top of the processing channel 12. An installation groove 14 is opened on the side of the working group 11 away from the processing channel 12. Transfer racks are provided on both sides of the working group 11 in the processing channel 12.

[0041] The rapid stamping and forming device for plastic cover plates provided in the embodiment is further optimized. Specifically, as Figure 2 shown, a heating component 20 is installed on one side of the processing channel 12 of the working group 11. A cooling component 60 is provided on the side of the processing channel 12 away from the heating component 20. A forming component 30 is installed on the side of the installation plate 15 close to the forming groove 13. A clamping component 40 is provided in the installation groove 14. A material transfer component 50 is installed in the forming groove 13. The heating component 20 is used to prevent the plastic plate blank after hot melting from cooling during the transfer process. The plastic plate blank is fixed by the clamping component 40, and then the plastic plate is die-cast into shape by the forming component 30. The material transfer component 50 is used to move the plastic cover plate out of the working group 11, and then the cooling component 60 is used to accelerate the cooling and forming of the plastic cover plate. Specifically, after the power is turned on, the transfer rack below the heating component 20 transfers the hot-melt softened plastic cover plate blank into the working group 11. During this period, the heating component 20 works to ensure that the plastic cover plate does not cool and harden before stamping. After stamping, the plastic cover plate slides down the blanking slope to the transfer rack at the bottom of the cooling component 60, and then is transferred to the next production process by it.

[0042] Furthermore, asFigure 4 As shown, the heating component 20 includes a heat preservation chamber 21 installed on the top of the conveyor rack. A number of mounting holes are provided in the top of the heat preservation chamber 21, and heating fans 22 are provided in each of the number of mounting holes. An electric heater 23 is installed on the side of the heating fan 22 close to the conveyor rack, and a heating motor 24 is coaxially connected to the heating fan 22 on the side away from the electric heater 23. After the power is turned on, the heating motor 24 drives the coaxially connected heating fan 22 to rotate, and blows the hot air heated by the electric heater 23 below it onto the hot-melt plastic cover plate on the conveyor rack, thereby preventing it from cooling and hardening.

[0043] Further, as Figure 5 As shown, the forming component 30 includes a forming hydraulic rod 31 fixedly connected to one side of the mounting plate 15. A pressing die 32 is fixedly connected to the piston end of the forming hydraulic rod 31. The pressing die 32 is located at the end of the forming hydraulic rod 31 away from the mounting plate 15. A number of sliding rods are slidably connected to both sides of the forming hydraulic rod 31, and a recovery spring 33 is sleeved on the periphery of each of the number of sliding rods. The clamping component 40 includes a clamping plate 41 installed on one side of the installation groove 14 close to the forming groove 13. A clamping hydraulic rod 42 is provided on the side of the clamping plate 41 away from the forming groove 13. The clamping plate 41 is fixedly connected to the piston end of the clamping hydraulic rod 42. An elastic member 43 is provided on one side of the clamping plate 41 with respect to the clamping hydraulic rod 42. The material transfer component 50 includes a material transfer hydraulic rod 51 fixedly connected to the bottom of the forming groove 13. A placement rack is fixedly connected to the piston end of the material transfer hydraulic rod 51. A number of rollers 52 are installed on the side of the placement rack away from the material transfer hydraulic rod 51. One end of one of the rollers 52 is coaxially connected to a material transfer motor 53. After the hot-melt softened plastic cover plate slides to the top of the forming groove 13 through the feeding slope, the clamping hydraulic rod 42 pushes the clamping plate 41 to fix the plastic cover plate. During this period, the elastic member 43 is stretched, and the spring inside it deforms. Then the forming hydraulic rod 31 drives the pressing die 32 to move towards the plastic cover plate. During this period, the recovery spring 33 is stretched. After the stamping is completed, the forming hydraulic rod 31 and the clamping hydraulic rod 42 are turned off, and the pressing die 32 and the clamping plate 41 are reset under the action of the restoring force of the spring inside the recovery spring 33 and the elastic member 43 respectively. Then the material transfer motor 53 drives the coaxially connected roller 52 to rotate, thereby transferring the stamped plastic cover plate to the conveyor rack below the ventilation rack 61.

[0044] Further, as Figure 6As shown in the figure, the cooling component 60 includes a ventilation frame 61 installed on the top of the conveyor frame. A number of card holes are provided on the top of the ventilation frame 61, and a cooling fan 62 is clamped in each of the card holes. A cooling motor 63 is coaxially connected to each of the cooling fans 62 on the side away from the conveyor frame. A pair of blanking slopes are provided in the processing channel 12, and the two blanking slopes are located between the forming groove 13 and the conveyor frame. The two blanking slopes are made of polycarbonate, and a number of rollers 52 are made of rubber. After the power is turned on, the cooling motor 63 drives the cooling fan 62 coaxially connected thereto to rotate, accelerating the air circulation rate around the plastic cover plate, thereby accelerating the cooling and forming of the plastic cover plate.

[0045] The usage process of the rapid stamping and forming device for plastic cover plates provided by the present utility model is as follows:

[0046] After the power is turned on, the conveyor frame below the heating component 20 conveys the hot-melt and softened plastic cover plate blank to the working group 11. During this period, the heating component 20 works to ensure that the plastic cover plate does not cool and harden before stamping. After stamping is completed, the plastic cover plate slides onto the conveyor frame at the bottom of the cooling component 60 through the blanking slope, and then is conveyed to the next production process by it. After the power is turned on, the heating motor 24 drives the heating fan 22 coaxially connected thereto to rotate, and blows the hot air heated by the electric heater 23 below it onto the hot-melt plastic cover plate on the conveyor frame, thereby preventing it from cooling and hardening. After the hot-melt and softened plastic cover plate slides to the top of the forming groove 13 through the blanking slope, the clamping hydraulic rod 42 pushes the clamping plate 41 to fix the plastic cover plate. During this period, the elastic member 43 is stretched, and the spring inside it deforms. Then the forming hydraulic rod 31 drives the pressing die 32 to move towards the plastic cover plate. During this period, the recovery spring 33 is stretched. After stamping is completed, the forming hydraulic rod 31 and the clamping hydraulic rod 42 are turned off, and the pressing die 32 and the clamping plate 41 are reset under the action of the recovery force of the spring inside the recovery spring 33 and the elastic member 43 respectively. Then the material transfer motor 53 drives the roller 52 coaxially connected thereto to rotate, thereby conveying the stamped plastic cover plate to the conveyor frame below the ventilation frame 61. Then the power of the cooling component 60 is turned on, and the cooling motor 63 drives the cooling fan 62 coaxially connected thereto to rotate, accelerating the air circulation rate around the plastic cover plate, thereby accelerating the cooling and forming of the plastic cover plate.
