Description

Technical Field

[0001] This application relates to the field of stamping technology, and more specifically, to a stamping and forming apparatus for PMI foam products. Background Technology

[0002] Polymethacrylimide (PMI) foam is a lightweight, closed-cell rigid foam. During its processing, a hydraulic stamping device is typically used to press the PMI foam raw material into a specific shape or structure. For example, Chinese patent CN202323436970.X discloses a PMI foam molding stamping device, which includes: a frame and a press table. The press table is fixedly connected to the top of the frame. Guide posts are fixedly connected to the four corners of the top surface of the press table. A mold is movably connected to the outer surface of the guide posts. A top plate is fixedly connected to the top of the guide posts. A motor is fixedly connected to the top of the top plate. A synchronous belt is movably connected to the outer surface of the motor's output end. The advantages of this invention are as follows: After the PMI foam material part is stamped, it is located on the press table. At this time, the output end of the control cylinder retracts. A new type of movable plate structure is designed. The movable plate approaches the foam material part until the negative pressure head contacts the foam material part. The negative pressure pump starts, and the negative pressure pipe cooperates with the negative pressure head to suck up the foam material part. Then the output end of the cylinder pushes out, and the movable plate pulls out the molded foam material part laterally. This completes the automatic material handling of the stamped foam material part, eliminating the need for manual material handling, making it more efficient and saving manpower.

[0003] However, the existing technology has certain limitations in use. The automatic material picking function of the above-mentioned device is only applicable to the whole product after molding.

These are prior art known to those skilled in the art and will not be described in detail here.

[0039] like Figures 1 to 4 As shown in the figure, this application provides a PMI foam product stamping and forming device, including a press table 1, a stamping component 2, a first waste adsorption component 3, and a product adsorption component 4. The stamping component 2 is disposed on the upper end of the press table 1. The first waste adsorption component 3 includes a first movable plate 31 and a first negative pressure suction head 32. The first movable plate 31 is slidably disposed on the upper end of the press table 1. The first negative pressure suction head 32 is fixedly disposed on the first movable plate 31 and is connected to an external air source. The press table 1 is provided with a first driving component 5 for moving the first waste adsorption component 3 to be closer to or away from the stamping area. The product adsorption component 4 is slidably disposed on the first movable plate 31. The product adsorption component 4 is used to adsorb and fix the stamped and formed product. The first movable plate 31 is provided with a second driving component 6 for moving the product adsorption component 4 to be closer to or away from the press table 1.

[0040] In use, the PMI foam material on the pressure table 1 is stamped and formed by the stamping component 2 to obtain the product and the surrounding waste. After stamping, the first driving component 5 drives the first movable plate 31 and the first negative pressure suction head 32 on it to move horizontally to the stamping area. Then, the first negative pressure suction head 32 is driven by an external air source to generate negative pressure to adsorb the waste. Then, the second driving component 6 drives the product adsorption component 4 to move vertically downward, so that it approaches and adsorbs the stamped product. Then, the second driving component 6 drives the product adsorption component 4 to rise, and the product rises with it. At this time, the waste is adsorbed and fixed by the first negative pressure suction head 32. Therefore, the product can be easily separated from the waste when it rises. Then, the first negative pressure suction head 32 is released from fixing the waste. Then, the first driving component 5 drives the first movable plate 31 and the product on it to move out of the stamping area, so that the product and waste can be collected separately.

[0041] This device integrates waste adsorption and product adsorption functions, thereby realizing the automatic separation and collection of products and waste after stamping. It solves the problem of mixed finished products and waste in the existing technology, which requires manual sorting, reduces the need for secondary manual separation operations, and effectively improves production efficiency. The device integrates the three steps of stamping, waste collection and product collection into one device to be completed continuously and automatically, saving labor costs and increasing the production cycle.

[0042] like Figures 1 to 3 As shown, in this embodiment, the first driving component 5 includes a first cylinder 51 and a first connecting plate 52. The first cylinder 51 is fixedly disposed at the lower end of the pressure table 1, and the piston rod of the first cylinder 51 is connected to the first connecting plate 52 and drives the first connecting plate 52 to move left and right. The first connecting plate 52 is fixedly connected to the first movable plate 31.

[0043] When in use, the first cylinder 51 is activated to drive the first connecting plate 52 to move left and right, and the first movable plate 31 moves left and right along with the first connecting plate 52.

[0044] like Figures 1 to 3 As shown, in this embodiment, a first extension plate 11 is fixedly provided on the side of the pressure table 1. The upper surface of the first extension plate 11 is flush with the upper surface of the pressure table 1. The first movable plate 31 is slidably provided on the upper end of the first extension plate 11. A clearance groove 12 is provided on the first extension plate 11. The first connecting plate 52 can pass through the clearance groove 12.

[0045] The first extension plate 11 extends the working plane of the pressure table 1, ensuring that the first movable plate 31 is well supported throughout the entire movement stroke; the clearance groove 12 provides movement space for the first connecting plate 52 connecting the first movable plate 31 and the first cylinder 51 below, ensuring that the movement path is unobstructed.

[0046] like Figures 1 to 4 As shown, in this embodiment, the product adsorption component 4 includes a second movable plate 41 and a second negative pressure suction head 42. The second negative pressure suction head 42 is fixedly disposed on the second movable plate 41 and is connected to an external air source.

[0047] When in use, the second negative pressure suction head 42 is driven by an external air source to generate negative pressure to adsorb the product.

[0048] like Figures 1 to 4 As shown, in this embodiment, multiple second negative pressure suction heads 42 are provided, and the multiple second negative pressure suction heads 42 are arranged in an array. Each second negative pressure suction head 42 can be controlled individually by an external controller.

[0049] The array of multiple second negative pressure suction heads 42 can evenly disperse the adsorption force, adapting to products of different sizes. This ensures that regardless of the product shape, there are enough suction points to provide stable and reliable adsorption force, preventing the product from falling off during transfer. Moreover, each second negative pressure suction head 42 can be individually controlled by an external controller. This means that only the second negative pressure suction head 42 corresponding to the product shape can be activated, avoiding waste areas, thereby achieving more precise suction and further optimizing the separation effect.

[0050] like Figures 1 to 4As shown, in this embodiment, the second drive assembly 6 includes a motor 61 and a screw 62. A groove 33 is provided on the side of the first movable plate 31. The screw 62 is rotatably disposed in the groove 33 through a bearing. The motor 61 is fixedly disposed on the first movable plate 31, and the output shaft of the motor 61 is connected to the screw 62. The second movable plate 41 is slidably disposed in the groove 33 and threadedly sleeved on the screw 62.

[0051] When in use, the motor 61 is turned on to drive the screw 62 to rotate. The second movable plate 41, which is threadedly engaged with the screw 62, is limited by the slide groove 33 to convert the rotational motion of the screw 62 into its own precise linear lifting motion. The screw 62 can then drive the second movable plate 41 to move up and down.

[0052] like Figures 1 to 3 As shown, in this embodiment, a second waste adsorption component 7 is also included. The second waste adsorption component 7 is symmetrically arranged with the first waste adsorption component 3. The second waste adsorption component 7 includes a third movable plate 71 and a third negative pressure suction head 72. The third movable plate 71 is slidably arranged on the upper end of the pressure table 1. The third negative pressure suction head 72 is fixedly arranged on the third movable plate 71 and is connected to an external air source. A third driving component 8 is provided on the pressure table 1 for moving the second waste adsorption component 7 to be close to or away from the stamping area.

[0053] In use, when the first waste adsorption component 3 adsorbs one side of the waste, the third driving component 8 drives the third movable plate 71 and the third negative pressure suction head 72 on it to move horizontally to the stamping area. Then, the external air source drives the third negative pressure suction head 72 to generate negative pressure to adsorb the other side of the waste. The simultaneous adsorption on both sides can balance the force and generate greater pulling force, adsorb and fix the waste more stably, and facilitate the smooth separation of the product from the waste when it rises.

[0054] like Figures 1 to 3 As shown, in this embodiment, the third drive assembly 8 includes a second cylinder 81 and a second connecting plate 82. The second cylinder 81 is fixedly disposed at the lower end of the pressure table 1, and the piston rod of the second cylinder 81 is connected to the second connecting plate 82 and drives the second connecting plate 82 to move left and right. The second connecting plate 82 is fixedly connected to the third movable plate 71.

[0055] When in use, the second cylinder 81 is activated to drive the second connecting plate 82 to move left and right, and the third movable plate 71 moves left and right along with the second connecting plate 82.

[0056] like Figures 1 to 3As shown, in this embodiment, a waste ejection assembly 9 is also included. The waste ejection assembly 9 includes a third cylinder 91 and a push plate 92. A second extension plate 13 is fixedly provided on the side of the pressure table 1. The third cylinder 91 is fixedly provided on the second extension plate 13, and the piston rod of the third cylinder 91 is connected to the push plate 92 and drives the push plate 92 to move back and forth.

[0057] When in use, after the product is removed from the stamping area, the third cylinder 91 is activated and the push plate 92 moves to the stamping area, pushing the residual waste on the press table 1 out of the press table 1 and pushing the waste into the external collection box or conveyor belt to achieve the final cleaning of the waste. Moreover, there is no need for manual cleaning of the table, which further improves production efficiency.

[0058] like Figures 1 to 3 As shown, in this embodiment, the stamping assembly 2 includes a guide post 21, a top plate 22, a hydraulic cylinder 23, and a die 24. The guide post 21 is fixedly disposed on the upper end of the press table 1, the top plate 22 is fixedly disposed on the upper end of the guide post 21, the hydraulic cylinder 23 is fixedly disposed on the top plate 22, and the piston rod of the hydraulic cylinder 23 is connected to the die 24 and drives the die 24 to move up and down. The die 24 is slidably sleeved on the guide post 21.

[0059] When in use, the hydraulic cylinder 23 is activated to drive the mold 24 to move up and down along the guide post 21, which can press the PMI foam material on the press table 1 into shape.

[0060] Working principle: When the PMI foam product stamping and forming device provided in this application is in use, the hydraulic cylinder 23 is turned on to drive the mold 24 to move up and down along the guide column 21, so that the PMI foam raw material on the press table 1 can be stamped and formed to obtain the product and the surrounding waste. After stamping, the first cylinder 51 is turned on to drive the first connecting plate 52 to move left and right. The first movable plate 31 and the first negative pressure suction head 32 on it move horizontally with the first connecting plate 52 to the stamping area. Then, the first negative pressure suction head 32 is driven by the external air source to generate negative pressure to adsorb one side of the waste. At the same time, the second cylinder 81 is turned on to drive the second connecting plate 82 to move left and right. The third movable plate 71 and the third negative pressure suction head on it move horizontally with the suction head of the second connecting plate 82 to the stamping area. Then, the third negative pressure suction head 72 is driven by the external air source to generate negative pressure to adsorb the other side of the waste.

[0061] Then, the motor 61 is activated to drive the screw 62 to rotate. The second movable plate 41, threadedly engaged with the screw 62, is limited by the slide groove 33, converting the rotational motion of the screw 62 into its own precise linear lifting motion. The screw 62 then drives the second movable plate 41 and its second negative pressure suction head 42 to move vertically downwards, bringing it close to the stamped product. An external air source drives the second negative pressure suction head 42 to generate negative pressure, adsorbing the product. Subsequently, the second drive assembly 6 drives the product adsorption assembly 4 to rise, and the product rises accordingly. The waste material is then trapped by the first negative pressure suction head 42. The suction head 32 adsorbs and fixes the product, so the product can be easily separated from the waste when it rises. Then, the first negative pressure suction head 32 releases the fixation of the waste, and the third negative pressure suction head 72 releases the fixation of the waste. Then, the first driving component 5 drives the first movable plate 31 and the product on it to move out of the stamping area. At the same time, the third driving component 8 drives the third movable plate 71 to move out of the stamping area. Then, the third cylinder 91 is activated to move the push plate 92 to the stamping area and push out the waste remaining on the press table 1, so that the product and waste can be collected separately.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
