Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of patch plate stacking equipment, in particular to a convex hull forming device for achieving stacking balance of hot-formed patch plates. Background Art
[0002] As the mold industry develops more and more rapidly, the mold development cycle is getting shorter and shorter, and the mass production stability of thermoformed parts is becoming more and more important. For thermoformed parts, it is basically necessary to ensure that they can be stacked flat one by one. Improving the flatness of the stacking can protect the adsorption of mass-produced parts and reduce the loading time. Generally, we will perform embossing on the progressive blanking to solve the problem of thickness balance of patch sheets. However, the commonly used method of tilting special material racks or pressing convex hulls on each sheet is not very ideal in stacking flatness, and there will still be a certain tilt phenomenon. We need to solve the problem of stacking balance. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, the utility model provides a convex hull forming device for achieving stacking balance of thermoformed patch plates. The device is suitable for thermoformed parts that require stacking balance of patch plates. The convex hulls are alternately made in the product process holes, and the convex hulls are formed in staggered order. The height of the convex hull is consistent with the material thickness of the patch plate to compensate for the imbalance caused by the different thickness of the patch plate material, and the stability of mass production is more guaranteed.
[0004] In order to achieve the above-mentioned purpose, a bulge forming device for achieving stacking balance of thermoformed patch plates is designed, including a base and an upper pressure plate. An upper pressure plate is provided above the base, a unloading slide is provided on one side of the base, and several pairs of guide blocks are provided on both sides above the base. Limit block one and limit block two are provided between the guide blocks above the base. A bulge forming structure is provided above the base, and the bulge forming structure includes a forming die, a pneumatic fixing block, a forming punch, and an air pipe. The pneumatic fixing block is embedded in the base, and the side of the pneumatic fixing block is connected to one end of the air pipe. One end of the forming punch is inserted into the pneumatic fixing block, and a forming die is embedded in the position corresponding to the forming punch in the upper pressure plate.
[0005] A sheet substrate 1 and a sheet substrate 2 are fixed between the upper pressing plate and the base.
[0006] The first surface of the material sheet substrate is processed to have a convex bulge one, and the second surface of the material sheet substrate is processed to have a convex bulge two. Both the first and second material sheet substrates are provided with patches.
[0007] The other end of the air pipe is connected to the cylinder.
[0008] The convex hull forming structures are provided with two in total, namely a convex hull forming device 1 and a convex hull forming device 2.
[0009] The plurality of sheet substrates 1 and 2 are placed alternately to form a stack of sheets.
[0010] Compared with the existing technology, the utility model adopts a step-by-step method to realize convex hull forming and progressive blanking. The convex hull forming is changed to different hulls being formed in a staggered manner, which compensates for the imbalance caused by the thickness of the patch plate, ensures the stability of the adsorption of the loading suction cup, and is also beneficial to the balance of the forklift transportation process. At the same time, it improves the problem of the sheets sticking together and being difficult to separate, and can also ensure the number of stacks, improving the problem of multiple small batch loading of patch plates in the past. More importantly, it ensures the balance and stability of the stacking of patch plate sheets, improves the loading efficiency, and reduces personnel input. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figure 4 As shown, an upper pressing plate 2 is provided above the base 1. Figure 1 As shown, a material discharge chute 10 is provided on one side of the base 1, and a plurality of pairs of guide blocks 13 are provided on both sides above the base 1. The guide blocks 13 limit the movement range of the sheet substrate 1.1 and the sheet substrate 2 1.2 to prevent the sheet from falling. A limit block 14.1 and a limit block 2 14.2 are provided between the guide blocks 13 above the base 1. The limit blocks 14.1 and the limit blocks 2 14.2 jointly limit the maximum feeding range of the sheet substrate on the base 1. A convex hull forming structure 5 is provided above the base 1, as shown in FIG. Figure 2 As shown, the convex hull forming structure 5 includes a forming die 6, a pneumatic fixing block 7, a forming punch 8, and an air pipe 9. The pneumatic fixing block 7 is embedded in the base 1, and the side of the pneumatic fixing block 7 is connected to one end of the air pipe 9. Figure 5 As shown, one end of a forming punch 8 is inserted into a pneumatic fixed block 7. A forming die 6 is embedded in the upper platen 2 at a position corresponding to the forming punch 8. The forming punch 8 can freely expand and contract within the pneumatic fixed block 7, retracting when not in use and extending during operation. A blank base 1.1 and a blank base 2 1.2 are fixed between the upper platen 2 and the base 1.
[0024] After processing, the surface of the sheet substrate 1.1 has a convex hull 3, and the surface of the sheet substrate 2 1.2 has a convex hull 2 4 after processing. Both the sheet substrate 1.1 and the sheet substrate 2 1.2 are provided with patches 15. Since different parts of the sheet have different force and structural requirements, different thicknesses need to be achieved in different parts, so patches 15 are provided for adjustment. The different forces on the sheet are balanced between the sheet substrate 1.1 and the sheet substrate 2 1.2 through alternating convex hulls.
[0025] The other end of the air pipe 9 is connected to the cylinder 12, and the cylinder 12 drives the expansion and contraction of the pneumatic fixing block 7.
[0026] like Figure 6 、 7 As shown, there are two convex hull forming structures 5, namely a first convex hull forming device 5.1 and a second convex hull forming device 5.2.
[0027] like Figure 8 、 9 As shown in FIG. 10 , a plurality of sheet substrates 1.1 and sheet substrates 2 1.2 are alternately placed to form a stack of sheets 11 .
[0028] The operation process of the utility model is as follows: the technician loads the material, and the sheet substrate 1.1 is loaded in the direction limited by the guide block 13 until one end of the sheet substrate 1.1 contacts the limit block 14.1 and the limit block 2 14.2 to lock the feed depth, the upper pressing plate 2 presses down to close the mold, and the convex forming structure 5.1 is driven by the cylinder 12 to extend, as shown in FIG. Figure 5 As shown, the surface of the sheet substrate 1.1 is processed to form a convex hull 3, the convex hull forming structure 1 5.1 shrinks, and the upper pressing plate 2 rises. The technician unloads the sheet substrate 1.1 and replaces it with the sheet substrate 2 1.2. The sheet substrate 2 1.2 is also fed in the direction limited by the guide block 13 until one end of the sheet substrate 1.1 contacts the limit block 14.1 and the limit block 2 14.2 to determine the feed depth. After the position is determined, the upper pressing plate 2 is pressed down to close the mold. At this time, the convex hull forming structure 2 5.2 extends, as shown in FIG. Figure 6 As shown, a bulge 2 4 is processed on the surface of the sheet substrate 2 1.2. After completion, the bulge forming structure 2 5.2 contracts, the upper pressure plate 2 rises, and then the processing process is repeated. There are two bulge positions, and repeated alternating processing is ensured to ensure that the bulge position is different from the bulge position of the previous sheet. For example, if the bulge formed on the sheet substrate 1.1 is bulge 2 4, then the bulge position of the next sheet substrate 2 1.2 is bulge 1 3. Finally, the sheets are stacked alternately in the form of one sheet substrate 1.1 plus one sheet substrate 2 1.2. This staggered forming method can make up for the imbalance caused by the thickness of the patch sheet. The stacking can achieve balance during feeding, and a larger number of sheet substrates can be transported than before.
