Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a side-cutting tool capable of trimming the perimeter of a water chamber.

[0004] The objective of this utility model can be achieved through the following technical solution: a side-cutting fixture for the perimeter of a water chamber, comprising:

[0005] Support components;

[0006] A support platform is provided on a support assembly, wherein a water chamber is inverted on the top of the support platform, and side-cutting assemblies are provided on both sides of the support platform, each of the side-cutting assemblies being slidably connected to the support assembly;

[0007] The upper mold assembly is movably positioned directly above the support assembly. The bottom surface of the upper mold assembly is provided with a stripper plate, which can move up and down relative to the upper mold assembly. The bottom surface of the stripper plate is provided with a pressing block that presses the water chamber onto the support platform. The bottom surface of the upper mold assembly is also provided with a punch for pushing the side cutting assembly towards the support platform.

[0008] In the aforementioned side-cutting fixture for a water chamber perimeter, the support assembly includes a lower mold base. The lower mold base is provided with a lower pad for mounting the support platform and the side-cutting assembly. The lower pad is provided with a pair of lower templates, which are respectively located at both ends of the support platform. A lower clamping plate is provided between each lower template and the lower pad.

[0009] In the aforementioned side-cutting fixture for the perimeter of a water chamber, the top of the support platform is provided with a contact platform for placing the water chamber, and the shape of the top of the contact platform is the same as the shape of the inner wall of the water chamber.

[0010] In the aforementioned side-cutting fixture for water chamber perimeter, there are gaps between the two sides of the support platform and the corresponding side-cutting components. The lower mold base and the lower pad are provided with chip removal grooves in the same number as the gaps. Each chip removal groove is located directly below an adjacent gap, and the chip removal groove is connected to the adjacent gap.

[0011] In the aforementioned side-cutting fixture for water chamber perimeter, each side-cutting component includes a fixed seat on a lower pad and a sliding block that can slide relative to the lower pad. Each sliding block has a cutter on its side facing the support platform, and the punch is located directly above the fixed seat and the sliding block.

[0012] In the aforementioned side-cutting fixture for the perimeter of a water chamber, the sliding block is provided with multiple movable rods, each of which moves through a fixed seat. A first spring is sleeved on the movable rod, wherein one end of the first spring abuts against the end of the movable rod away from the sliding block, and the other end of the first spring abuts against the inner wall of the fixed seat.

[0013] In the aforementioned side-cutting fixture for the water chamber perimeter, the top of the sliding block has a lower inclined surface facing the fixed seat, the bottom surface of the punch has an upper inclined surface corresponding to the lower inclined surface, and the fixed seat has a notch for inserting the bottom of the punch on the side facing the sliding block.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figure 1 — Figure 10 As shown, the side-cutting fixture for water chamber surround of this utility model includes a support assembly 100, a support platform 200, a water chamber 300, a side-cutting assembly 400, an upper mold assembly 500, a stripper plate 510, a pressing block 511, and a punch 520.

[0031] A support platform 200 is mounted on a support assembly 100. A water chamber 300 is inverted and rests on the top of the support platform 200. Side-cutting assemblies 400 are located on both sides of the support platform 200, each of which is slidably connected to the support assembly 100. An upper mold assembly 500 is movably positioned directly above the support assembly 100. A stripper plate 510 is located on the bottom surface of the upper mold assembly 500. The stripper plate 510 can move up and down relative to the upper mold assembly 500. A pressing block 511 is located on the bottom surface of the stripper plate 510 to press the water chamber 300 onto the support platform 200. A punch 520 is also located on the bottom surface of the upper mold assembly 500 to push the side-cutting assemblies 400 towards the support platform 200. The pressing block 511... The bottom surface is provided with a pressing surface 512 for embedding the water chamber 300. The top of the support platform 200 is provided with a contact platform 210 for placing the water chamber 300. The shape of the top of the contact platform 210 is the same as the shape of the inner wall of the water chamber 300. When cutting the perimeter 310 of the water chamber 300, it is necessary to ensure that there is a predetermined distance between the upper mold assembly 500 and the support assembly 100. That is, the upper mold assembly 500 must first be raised to the initial height so that the water chamber 300 can be inverted onto the contact platform 210 of the support platform 200, so that the perimeter 310 on both sides of the water chamber 300 is located between the support platform 200 and the corresponding side cutting assembly 400, respectively. After that, the upper mold assembly 500 is controlled to descend. During this process, the stripper plate 510 will preferentially... The contact support assembly 100 is engaged, and simultaneously, the water chamber 300 is embedded into the pressing surface of the pressing block 511. The punch 520 contacts the adjacent side-cutting assembly 400. Afterward, the stripper plate 510 remains stationary relative to the support assembly 100, and the upper die assembly 500 continues to descend relative to the support assembly 100. Because the punch 520 is connected to the upper die assembly 500, the punch 520 descends with the upper die assembly 500. Thus, the punch 520 drives the corresponding side-cutting assembly 400 to move towards the support table 200. During this process, a shearing force is formed between the side-cutting assembly 400 and the bottom surface of the contact table 210, thereby enabling the side-cutting assembly 400 to cut the perimeter 310. When the upper die assembly 500 abuts against the stripper plate 510, the upper die assembly 500 will... The descent stops, and simultaneously, the punch 520 stops descending, and the side-cutting assembly 400 also stops moving. In this way, the side-cutting assembly 400 can complete the cutting work on the perimeter 310, so that the height of the perimeter 310 of the water chamber 300 meets the processing requirements and the perimeter 310 of the water chamber 300 is more flush. After the cutting is completed, the upper die assembly 500 returns to its initial height. During this process, the punch 520 will also rise, and the side-cutting assembly 400 will automatically return to its original position. When the side-cutting assembly 400 has returned to its original position, the punch 520 will only contact the side-cutting assembly 400, and the stripper plate 510 will remain stationary. After that, the stripper plate 510 will rise synchronously with the upper die assembly 500, and then the water chamber 300 that has been cut can be removed from the contact table 210.

[0032] like Figure 1 — Figure 7 As shown, the support assembly 100 includes a lower mold base 110. The lower mold base 110 is provided with a lower pad 120 for mounting the support platform 200 and the side-cutting assembly 400. The lower pad 120 is provided with a pair of lower templates 130, which are respectively located at both ends of the support platform 200. A lower clamping plate 140 is provided between each lower template 130 and the lower pad 120. There is a gap 220 between the two sides of the support platform 200 and the corresponding side-cutting assembly 400. Both the lower mold base 110 and the lower pad 120 are provided with a number of [missing information - likely related to gaps 220]. The same chip removal grooves are provided, each of which is located directly below an adjacent gap 220 and is connected to the adjacent gap 220. Before cutting, when the water chamber 300 is inverted on the contact table 210, the edge 310 will be inserted into the corresponding gap 220. When the side cutting component 400 cuts the edge 310, the waste material cut off on the edge 310 will fall into the corresponding gap 220. After that, the waste material can be smoothly discharged through the chip removal grooves of the lower pad 120 and the lower mold base 110, thus facilitating the cleaning of the tooling.

[0033] Each of the side-cutting components 400 includes a fixed seat 410 disposed on a lower pad 120 and a sliding block 420 slidable relative to the lower pad 120. Each sliding block 420 has a cutter 421 on its side facing the support platform 200. The punch 520 is located directly above the fixed seat 410 and the sliding block 420. Specifically, the sliding block 420 has multiple movable rods 422, each of which movably passes through the fixed seat 410. A first spring 411 is sleeved on each movable rod 422, with one end of the first spring 411 abutting against the end of the movable rod 422 away from the sliding block 420, and the other end abutting against the inner wall of the fixed seat 410. The top of the sliding block 420 has a lower inclined surface 423 facing the fixed seat 410, and the bottom surface of the punch 520 has an upper inclined surface 521 corresponding to the lower inclined surface 423. The fixed seat 410... The side of the sliding block 420 facing the punch 520 has a notch 412 for inserting the bottom of the punch 520. When the stripper plate 510 contacts the lower template 130, the bottom edge of the upper inclined surface 521 of the punch 520 contacts the lower inclined surface 423. After that, the punch 520 continues to descend, and the upper inclined surface 521 will exert a force on the lower inclined surface 423. Since the sliding block 420 is movably connected to the fixed seat 410 through multiple movable rods 422, and the fixed seat 410 is fixedly connected to the lower pad 120, the sliding block 420 and the movable rods 422 move relative to the fixed seat 410 towards the support platform 200. During this process, the first spring 411 is compressed and generates a corresponding elastic force. When the punch 520 rises, the movable rod 422 will always be subjected to the elastic force of the first spring 411, so that the movable rod 422 carries the sliding block 420 to perform a reset movement towards the fixed seat 410 until the sliding block 420 abuts against the fixed seat 410.

[0034] Furthermore, when the stripper plate contacts the lower template, the bottom surface of the pressing block is flush with the bottom surface of the contact table, and the top surface of the cutter contacts the bottom surface of the pressing block. Thus, as the cutter moves towards the support table, it will generate shearing force with the edge of the bottom surface of the contact table, thereby smoothly cutting the surrounding edge. When the side of the top surface of the cutter close to the support table contacts the bottom surface of the contact table, the cutting is completed. At the same time, the bottom surface of the punch abuts against the bottom of the notch.

[0035] like Figure 1 , Figure 4 and Figure 7 — Figure 10 As shown, further, when the bottom of the upper inclined surface 521 abuts against the lower inclined surface 423, the bottom of the punch 520 will insert into the notch 412. At the same time, the side of the punch 520 away from the upper inclined surface 521 will abut against the inner wall of the notch 412, thereby counteracting the reaction force of the sliding block 420 on the punch 520, so that the punch 520 can smoothly push the sliding block 420 to move.

[0036] The upper mold assembly 500 has multiple second springs 530 connected to the stripper plate 510 inside. The upper mold assembly 500 includes an upper mold base 550, an upper pad 560, an upper clamping plate 570, and a stripper backing plate 580 arranged sequentially from top to bottom. The stripper plate 510 has multiple connecting bolts 581. The end of each connecting bolt 581 away from the stripper plate 510 is movably engaged in the upper pad 560. The diameter of the end of the connecting bolt 581 away from the stripper plate 510 is larger than the diameter of the middle part of the connecting bolt 581. The upper pad 560... 0. Both the upper clamping plate 570 and the backing plate 580 allow connecting bolts 581 to move through bolt holes 561. The diameter of the bolt holes 561 in the upper backing plate 560 is larger than the diameter of the bolt holes 561 in the upper clamping plate 570. The diameter of the bolt holes 561 in the upper clamping plate 570 is the same as the diameter of the middle portion of the connecting bolts 581. When the upper mold assembly 500 is suspended, the stripper plate 510 is subjected to gravity, creating a certain distance between the stripper plate 510 and the backing plate. At this time, the connecting bolts 581 are away from the stripper plate 510. One end of the stripper plate 510 abuts against the upper clamping plate 570 to prevent it from separating from the upper mold assembly 500. When the stripper plate 510 abuts against the lower mold plate 130 and the upper mold assembly 500 continues to descend, the upper mold base 550, upper pad 560, upper clamping plate 570, and stripper back plate 580 will descend synchronously relative to the stripper plate 510. The distance between the stripper back plate 580 and the stripper plate 510 will decrease. At this time, the second spring 530 will be compressed, and the end of the connecting bolt 581 away from the stripper plate 510 will move within the bolt hole 561 of the upper pad 560. When the edge 310 is cut and the upper mold assembly 500 rises, the stripper plate 510 will still abut against the lower mold plate 130 due to its own gravity and the elastic force of the second spring 530. The end of the connecting bolt 581 away from the stripper plate 510 will move in the bolt hole 561 of the upper pad plate 560. When the end of the connecting bolt 581 away from the stripper plate 510 abuts against the upper clamping plate 570, the upper mold assembly will rise synchronously with the stripper plate 510, thereby separating the stripper plate 510 from the lower mold plate 130.

[0037] The upper mold assembly 500 is provided with a plurality of guide pillars 540, which move through the stripper plate 510. The lower mold plate 130 and the lower clamping plate 140 are provided with guide holes 131 for inserting the guide pillars 540. When the tooling is closed, each guide pillar 540 will be inserted into the corresponding guide hole 131 so that the water chamber 300, which is inverted on the contact table 210, can be smoothly embedded into the pressing surface.

[0038] In this utility model, the upper mold base 550 and the lower mold base 110 need to be installed inside a hydraulic press (not shown in the figure). Specifically, the upper mold base 550 needs to be installed on the lifting mechanism (not shown in the figure) of the hydraulic press, and the lower mold base 110 needs to be installed at the bottom of the hydraulic press (not shown in the figure). During operation, the lifting mechanism (not shown in the figure) drives the upper mold base 550 to rise and fall, while the lower mold base 110 remains stationary. Specifically, the lifting mechanism can be a hydraulic cylinder (not shown in the figure) with a piston rod (not shown in the figure), and the hydraulic cylinder is installed at the top of the hydraulic press.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
