Description

Technical Field

[0001] This application relates to the technical field of stamping, and in particular to a stamping apparatus for aluminum alloy decorative parts. Background Technology

[0002] Aluminum alloys are widely used in decorative applications across numerous industries, including construction, automotive, electronics, and furniture, due to their numerous advantages such as light weight, high strength, corrosion resistance, ease of processing and forming, and good surface treatment properties. In the construction industry, aluminum alloy decorative components are extensively used in curtain walls, door and window frames, railings, and handrails, not only enhancing the aesthetics and modernity of buildings but also meeting the structural requirements for material strength and durability.

[0003] In the production process of aluminum alloy decorative parts, some parts need to be stamped. Stamping is a forming process that uses a press and mold to apply external force to sheet metal, strip, tube and profile, so as to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0004] There are various forms of stamping for aluminum alloy decorative parts. For example, some use conveyor belts for transport and the stamping head reciprocates for stamping. Others use a rotary table structure, where the stamping operation is completed by the rotation of the table at a fixed angle. In the latter type, scrap material falls directly onto the rotary table and slides down it. However, due to the small burrs remaining after stamping, the friction increases, and the sliding process may not be entirely smooth. During subsequent rotations of the rotary table, scrap material may fall onto the processing platform, resulting in poor platform cleanliness. Therefore, to solve the above problems, this application provides an aluminum alloy decorative part stamping device. Utility Model Content

[0005] To address the problem of untimely waste removal in existing rotary stamping devices, this application provides an aluminum alloy decorative parts stamping device.

[0007] The turntable is equipped with a pressure chamber that is fixed to the machine body by a fixing frame. The pressure chamber is connected to the outside through an external pipe. A solenoid valve is installed in front of the pressure chamber of the pressure chamber. A contact sensor is also installed on the outside of the pressure chamber for use with it.

[0008] By setting a pressure box on the turntable and upgrading the existing mold by adding a docking block that cooperates with the pressure box, and opening air grooves with gradually decreasing width in the docking block, the gas in the pressure box enters the waste chamber through the air grooves to perform secondary cleaning of the residual waste in the waste chamber, thereby achieving complete waste discharge.

[0009] Preferably, the fixed mold further includes a partition plate located between the docking cavity and the waste cavity. The partition plate has holes and grooves on both sides, and positioning blocks are welded at the four corners of the partition plate.

[0010] Preferably, the stamping mechanism includes a hydraulic cylinder, the output end of which is connected to a bracket, and a moving mold is fixedly connected to the bottom of the bracket, the moving mold cooperating with a fixed mold located directly below it.

[0011] Preferably, the moving mold includes a base fixedly connected to the bracket, a pressure block welded below the base, the pressure block slidingly engaging with the mating cavity, and a protruding ridge welded below the pressure block, the protruding ridge slidingly engaging with the slot.

[0012] Preferably, each of the four corner positions of the pressure block is slidably fitted with a pressure post, the pressure posts are elastically connected to the pressure block by springs, and the bottom end of the pressure post is provided with a protruding ridge when it is not under the thrust.

[0013] Preferably, a waste trough is welded onto the machine body, and a waste bin that engages with the machine body is provided at the end of the waste trough.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0026] Example 1:

[0027] A stamping device for aluminum alloy decorative parts, as described in the reference. Figure 1 - Figure 8 The machine body 1 has a rotating turntable 2. A stamping mechanism and a feeding mechanism 10 for transfer are provided on one side of the turntable 2. The feeding mechanism 10 includes two cylinders, a finger cylinder, the turntable 2, a connecting rod, and a connecting component structure. The turntable 2 is rotatably connected to the support frame of the stamping mechanism. The axis of the turntable 2 is rotatably connected to the output end of the horizontally set cylinder through the connecting rod. The other vertically set cylinder is fixed to the center position of the bottom of the turntable 2 through the connecting component. The output end of the vertically set cylinder is fixedly connected to the finger cylinder. The movement of the device is as follows: the horizontally set cylinder extends and retracts, and rotates the turntable 2 through the connecting rod. The bottom of the turntable 2 is connected to the vertically set cylinder through the connecting piece to move radially around the turntable 2, so as to realize the rotation of the finger cylinder from the work position to the material feeding position on the top view. The vertically set cylinder controls the downward extension of the finger cylinder to complete the operation of picking up the material and putting it into the material trough 7. A fixed mold 6 is installed on the turntable 2. The fixed mold 6 is provided with a docking cavity 62 and a waste cavity 61 above and below it, respectively. The turntable 2 is provided with a material leakage trough 21 below each waste cavity 61.

[0028] The machine body 1 is also welded with a waste trough 8. At the end of the waste trough 8 is a waste box 9 that is snapped into the machine body 1. The waste box 9 has an L-shaped structure and a protruding strip at the bottom. The machine body 1 has a snap-fit ​​groove that snaps into the protruding strip for easy placement of the waste box 9.

[0029] The stamping mechanism includes a hydraulic cylinder 3, the output end of which is connected to a bracket 4. A moving die 5 is fixedly connected to the bottom of the bracket 4. The moving die 5 works in conjunction with a fixed die 6 located directly below it. The moving die 5 includes a base 51 fixedly connected to the bracket 4. A pressure block 52 is welded to the bottom of the base 51. The pressure block 52 and the mating cavity 62 are slidably fitted together. A protruding rib 53 is welded to the bottom of the pressure block 52. The protruding rib 53 and the slot 65 are slidably fitted together. The pressure block 52 is used to press the aluminum alloy, and the protruding rib 53 works with the slot 65 to cut the aluminum alloy, thereby completing the stamping effect. Pressure columns 54 are slidably embedded at the four corners of the pressure block 52. The pressure columns 54 are elastically connected to the pressure block 52 by springs 55. The bottom of the pressure column 54 has a protruding ridge 53 when it is not under the thrust. When the hydraulic cylinder 3 pushes the bracket 4 down, the pressure column 54 first presses the four corners of the aluminum alloy surface to ensure the stability of the aluminum alloy part. Then, when the hydraulic cylinder 3 continues to go down, the ridge 53 will cooperate with the hole groove 65 below to cut the aluminum alloy part. The ridge 53 pushes the waste into the waste chamber 61, and then the pressure box 11 sprays high-pressure gas.

[0030] The rear end of the fixed mold 6 is welded with a docking block 66, and the inner side of the docking block 66 is provided with an air groove 661 that runs through it and the fixed mold 6. The opening of the air groove 661 facing the waste chamber 61 is smaller than that of the other side. The shape of the air groove 661 allows the gas ejected from the pressurization box 11 to be further accelerated when passing through its structure, thereby further improving the cleaning efficiency. The fixed mold 6 also includes a partition plate located between the docking chamber 62 and the waste chamber 61. The partition plate is provided with holes and slots 65, and grooves 64 are provided on both sides. Positioning blocks 63 are welded at the four corners of the partition plate. The holes and slots 65 on the partition plate correspond to the positions where the aluminum alloy decorative parts need to be opened. The positions of the holes and slots 65 can be opened according to requirements. The grooves 64 are to match the position of the finger cylinder, making it easier for the finger cylinder to grasp. The top opening of the positioning block 63 is larger than the bottom opening, which facilitates the placement of the aluminum alloy decorative parts into the fixed mold 6.

[0031] A pressure chamber 11 is fixed to the machine body 1 by a fixing frame on the turntable 2. The chamber of the pressure chamber 11 is connected to the outside through an external pipe 111. A solenoid valve 112 is installed in front of the pressure chamber of the pressure chamber 11. A contact sensor 113 is also installed on the outside of the pressure chamber 11 for use with it. The purpose of the contact sensor 113 is to monitor whether the docking block 66 of the fixed mold 6 is in place. The external gas supply equipment pumps gas into the pressure chamber of the pressure chamber 11 through a pump. At this time, the pipe and the solenoid valve 112 on the pressure chamber 11 are closed. After the contact sensor 113 detects that the docking block 66 is in place, the solenoid valve 112 of the pressure chamber 11 is opened, and the pressurized gas inside will be ejected from the outlet position. After passing through the gas groove 661, it enters the waste chamber 61, pushing the waste material stored in the waste chamber 61 to the outside, avoiding the residue of waste material in the leakage groove 21.
