Description

Technical Field

[0001] This invention relates to the technical field of waterproof membrane processing, and in particular to a waterproof membrane processing apparatus. Background Technology

[0002] Waterproofing membranes, as a crucial seepage prevention material, play an irreplaceable role in building construction, tunnel construction, underground facilities, and water conservancy projects. To meet the drainage, connection, or fixing needs of different engineering structures, precise perforation is typically required on the waterproofing membranes. With the development of industrialized construction and prefabricated technology, higher demands are placed on the processing efficiency, precision, and adaptability of waterproofing membrane components. This makes efficient, precise, and highly adaptable automated processing equipment an urgent need for the industry's development.

[0003] Traditional waterproof membrane punching devices have seen some improvements in waste disposal. For example, by setting up waste channels in the punch unit and using movable sealing parts to control the temporary storage and discharge of waste, the problems of waste splashing and accumulation during processing are effectively avoided. However, these devices still have significant limitations in practical applications: First, their structure is usually relatively fixed, and the clamping and positioning mechanisms are difficult to adjust flexibly and quickly according to waterproof membranes of different sizes and shapes. This leads to the waterproof membrane being prone to loosening or displacement during continuous punching, directly affecting the positional accuracy of punching and the product yield. Second, the movement freedom of the punching unit is limited, and the positioning system is relatively simple, often only able to punch in a single direction or at a limited number of positions. This cannot meet the processing needs of multi-angle, multi-position hole groups on complex waterproof membranes, greatly limiting the application of this device in diverse and refined production scenarios. Therefore, there is an urgent need for a new type of waterproof membrane processing device with better clamping stability, higher positioning flexibility, and stronger size adaptability to overcome the shortcomings of existing technologies.

A spring is connected to the side of the slider away from the third push plate. A fourth limiting block is connected to the lower outer wall of the slider. A groove is opened in the middle of the upper outer wall of the fourth limiting block.

[0006] Furthermore, a punching mechanism is connected to one side of the upper end of the workbench. The punching mechanism includes a slide rod fixedly connected to the upper end of the workbench, and a fourth cylinder is connected to the upper end of the slide rod.

[0007] Furthermore, a movable block is slidably connected to the outer wall of the upper end of the slide rod, and a limit groove is formed on one side of the outer wall of the movable block.

[0008] Furthermore, the inner wall of the limiting groove is connected to the punching device body, and a third cylinder is connected to one side of the outer wall of the punching device body.

[0009] Furthermore, the first push plate is movably connected to the upper outer wall of the worktable, the second push plate is movably connected to the upper outer wall of the worktable, the third push plate is movably connected to the upper outer wall of the worktable, and the fixed plate is movably connected to the upper outer wall of the worktable, and the first push plate, the second push plate, the third push plate and the fixed plate are slidably connected to each other in a staggered manner.

[0010] Furthermore, the first limiting block is fixedly connected to the outer wall of one side of the worktable, and the inner wall of the first limiting block is limitedly connected to the cylinder body or piston rod of the first cylinder.

[0011] Furthermore, the punching device body is located above the processing area enclosed by the first push plate, the second push plate, the third push plate, and the fixed plate, and the outer wall of the punching device body is slidably connected to the inner wall of the limiting groove.

[0012] Furthermore, the second limiting block is fixedly connected to the outer wall of one side of the worktable, and the inner wall of the second limiting block is limitedly connected to the cylinder body or piston rod of the second cylinder.

[0013] Furthermore, the fourth limiting block is fixedly connected to the outer wall of one side of the worktable, and the inner wall of the fourth limiting block forms a receiving cavity. The slider and the spring are disposed in the receiving cavity and are limitedly connected to the fourth limiting block.

[0014] Furthermore, one end of the spring is connected to the slider, and the other end of the spring is connected to the inner wall of the fourth limiting block. The slider slides in cooperation with the fourth limiting block through the groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting an adjustable clamping system on the worktable consisting of a first pusher plate, a second pusher plate, a third pusher plate, and a fixed plate, can dynamically adapt to and perform multi-point coordinated clamping on waterproof sheet workpieces of different sizes and specifications. Each pusher plate moves along a set trajectory under the control of an independent drive mechanism, forming a variable clamping area. This provides a uniform, reliable, and adjustable clamping force to the workpiece throughout the punching process, effectively suppressing any displacement, vibration, or warping that may occur during punching, significantly improving the stability of the processing and the positioning accuracy of the final hole.

[0016] 2. This invention achieves automated and programmed control of the clamping action by integrating the first and second cylinders as the direct power source for the first and second push plates. Based on preset instructions or sensor feedback, the system can quickly and accurately execute clamping and releasing operations, significantly reducing the time required for manual adjustment and intervention, improving the processing cycle time of individual products and overall production efficiency. It also reduces clamping force fluctuations caused by inconsistent human operation, ensuring process stability and product consistency in mass production.

[0017] 3. This invention, through the coordinated drive of the third and fourth cylinders and the guiding structure of the slide rod and movable block, endows the punching device body with precise movement capabilities in multiple degrees of freedom. Specifically, this design enables the punching unit to not only perform vertical punching operations but also to perform precise two-dimensional positioning in the horizontal plane, and even achieve tilted punching at specific angles through linkage control. This flexible positioning function with multiple angles and positions allows it to easily handle the processing requirements of complex hole patterns and multi-angle inclined holes on waterproof membranes, greatly expanding the equipment's process applicability and processing flexibility.

[0018] 4. This invention establishes high-precision mechanical constraints and running tracks for all moving parts through a composite limiting and guiding mechanism composed of first, second, third, and fourth limiting blocks, sliders, and grooves. This design ensures that every movement of the first, second, and third push plates, as well as the punching device body, follows a preset path, effectively eliminating swaying and erratic movement during operation. The coordinated movement of the slider within the groove and the buffer design of the spring further enhance the adaptability and stability of the third push plate mechanism during clamping. The entire limiting and guiding system works together to fundamentally guarantee the overall mechanical stability, repeatability, and long-term reliability of the device. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 5 This invention provides a technical solution: a waterproof membrane processing device, including a workbench 1. A plurality of support legs 2 are fixedly connected to the lower end of the workbench 1 by welding or bolts. The support legs 2 are preferably made of rigid metal material to provide stable support. A first push plate mechanism 3, a second push plate mechanism 4, and a third push plate mechanism 5 are slidably connected to the upper outer wall of the workbench 1. A fixing plate 6 is fixedly connected to the upper outer wall of the workbench 1 by bolts or welding.

[0023] The first push plate mechanism 3 includes a first push plate 31 movably connected to the outer wall of one side of the upper end of the worktable 1 via a bottom slide rail or slide groove. The outer wall of one side of the first push plate 31 is fixedly connected to the piston rod end of the first cylinder 32 via a connector. A first limiting block 33 is connected to the outer wall of one side of the cylinder body of the first cylinder 32. The cylinder body of the first cylinder 32 is fixed to the first limiting block 33 by bolts, or its piston rod passes through the first limiting block 33 and is limited by it.

[0024] The second push plate mechanism 4 includes a second push plate 41 movably connected to the outer wall of one side of the upper end of the worktable 1 via a bottom slide rail or slide groove. The outer wall of one side of the second push plate 41 is fixedly connected to the piston rod end of the second cylinder 42 via a connector. A second limiting block 43 is connected to the outer wall of one side of the cylinder body of the second cylinder 42. The cylinder body of the second cylinder 42 is fixed to the second limiting block 43 by bolts, or its piston rod passes through the second limiting block 43 and is limited by it.

[0025] The third push plate mechanism 5 includes a third push plate 51 movably connected to the outer wall of one side of the upper end of the worktable 1 via a bottom slide rail or slide groove. A slider 52 is fixedly connected to the outer wall of one side of the third push plate 51 by welding or bolts. A third limiting block 53 is fixedly connected to both sides of the slider 52 along its sliding direction. A spring 54 is connected to the side of the slider 52 away from the third push plate 51. The spring 54 is preferably a compression spring. The lower outer wall of the slider 52 is slidably connected to a fourth limiting block 55. The fourth limiting block 55 is fixedly connected to the outer wall of one side of the worktable 1 by bolts. A long strip-shaped slide groove 56 is formed in the middle of the upper outer wall of the fourth limiting block 55 along the movement direction of the slider 52. The third limiting blocks 53 on both sides of the slider 52 are embedded in the slide groove 56 and can slide along it, thereby accurately guiding and limiting the movement path of the slider 52 and preventing it from deflecting. One end of the spring 54 is connected to the slider 52, and the other end is connected to the inner wall of the fourth limiting block 55.

[0026] The worktable 1 is provided, and the first push plate mechanism 3, the second push plate mechanism 4, the third push plate mechanism 5, and the fixed plate 6 are respectively connected to the upper end of the worktable 1. The first push plate mechanism 3 is driven by the first cylinder 32, and the second push plate mechanism 4 is driven by the second cylinder 42. Since the first push plate 31, the second push plate 41, the third push plate 51, and the fixed plate 6 are arranged in a circular pattern on the worktable 1, and their sliding paths partially overlap or are adjacent to each other, they can contact each other and transmit thrust during sliding. The fixed plate 6 is fixed. When the first push plate 31 moves towards the central region under the drive of the first cylinder 32, and / or the second push plate 41 moves towards the central region under the drive of the second cylinder 42, they will sequentially push the third push plate 51 towards the fixed plate 6. The third push plate 51 slides within the fourth limiting block 55 via the slider 52 connected to it. The cooperation between the third limiting blocks 53 on both sides of the slider 52 and the slide groove 56 ensures the straightness and stability of the sliding process. During this process, the spring 54 is compressed and stores energy. When the first cylinder 32 and the second cylinder 42 retract, driving the first push plate 31 and the second push plate 41 to reset, the third push plate 51 moves in the opposite direction to reset under the restoring force of the spring 54. Through the coordinated displacement of the first push plate 31, the second push plate 41, the third push plate 51, and the fixed plate 6, the size of the clamping cavity they form in the middle can be flexibly changed, thereby adapting to and firmly clamping waterproof plates of different shapes and sizes, providing stable workpiece positioning for subsequent punching operations.

[0027] like Figure 1 , Figure 5As shown, a punching mechanism 7 is connected to the outer wall of one side of the upper end of the worktable 1. The punching mechanism 7 includes at least one slide rod 76 fixedly connected to the outer wall of the upper end of the worktable 1. The slide rod 76 is preferably an optical axis or a linear guide rail. A movable block 71 is slidably connected to the outer wall of the upper end of the slide rod 76. The movable block 71 has a sliding bearing or slider that matches the slide rod 76 inside. A fourth cylinder 75 is fixedly connected to one end or above the slide rod 76. The cylinder body of the fourth cylinder 75 is fixed, and its piston rod is connected to the movable block 71 to drive the movable block 71 to move precisely in a straight line along the length direction of the slide rod 76. A limiting groove 72 is formed on one side of the outer wall of the movable block 71. The cross-sectional shape of the limiting groove 72 matches the corresponding part of the punching device body 73, for example, it can be a rectangular groove or a T-shaped groove. The punching device body 73 is slidably connected to the inner wall of the limiting groove 72, and a third cylinder 74 is connected to one side of the outer wall of the punching device body 73. The cylinder body of the third cylinder 74 is fixed on the movable block 71, and its piston rod is connected to the punching device body 73, which drives the punching device body 73 to move linearly in a direction perpendicular to the axis of the slide rod 76 (or the guiding direction of the limiting groove 72). The punching device body 73 itself contains necessary components such as a motor and a punch to realize the punching function, which is prior art and will not be described in detail here.

[0028] It should be noted that the combined motion of the fourth cylinder 75 driving the movable block 71 to move along the slide rod 76, and the third cylinder 74 driving the punching device body 73 to move along the limiting groove 72, enables the punching device body 73 to perform two-dimensional precise positioning in a plane parallel to the worktable 1. Combined with the vertical punching motion of the punching device body 73, punching can be performed at any predetermined position on the clamped waterproof membrane within the area above the clamping cavity formed by the first push plate 31, the second push plate 41, the third push plate 51, and the fixed plate 6. This design greatly enhances the adaptability to waterproof membranes of different sizes and punching requirements at different positions on the membrane, improving the processing flexibility and practicality of the device.

[0029] The working principle of the above embodiment is as follows: During operation, the waterproof plate to be punched is first placed on the upper end of the workbench 1, and located in the center of the area initially enclosed by the first pushing plate 31, the second pushing plate 41, the third pushing plate 51, and the fixed plate 6. Then, the first cylinder 32 and the second cylinder 42 are activated. The piston rod of the first cylinder 32, supported by the first limiting block 33, extends and pushes the first pushing plate 31 to slide along its set track towards the waterproof plate on the workbench 1. At the same time, the piston rod of the second cylinder 42, supported by the second limiting block 43, extends and pushes the second pushing plate 41 to slide along its set track towards the waterproof plate on the workbench 1. Due to the relative positional relationship between the plates, the movement of the second pushing plate 41 will push the first pushing plate 31, and the movement of the first pushing plate 31 will push the third pushing plate 51. Since the fixed plate 6 is in a fixed position, when the third pushing plate 51 is pushed, it will drive the slider 52 to slide within the fourth limiting block 55 along the direction defined by the slide groove 56, and compress the spring 54. Finally, the four plates simultaneously or sequentially contact and press the edge of the waterproof plate from different directions, automatically adjusting the clamping position according to the actual size of the waterproof plate to form a stable and reliable clamping state.

[0030] After clamping, the punching process is initiated. The fourth cylinder 75 operates, driving the movable block 71 to carry the punching device body 73 along the slide rod 76 to the X-axis (or Y-axis) coordinate position of the target hole. Next, the third cylinder 74 operates, driving the punching device body 73 to slide within the limiting groove 72, moving it to the Y-axis (or X-axis) coordinate position of the target hole. After two-dimensional planar positioning is completed, the punching device body 73 performs a vertically downward punching action, completing the punching. By controlling the coordinated action of the third cylinder 74 and the fourth cylinder 75 through program control, multiple holes on the waterproof membrane can be precisely processed continuously and automatically.

[0031] After processing is completed, the piston rods of the first cylinder 32 and the second cylinder 42 are retracted, causing the first push plate 31 and the second push plate 41 to reset. At this time, the third push plate 51, having lost the thrust from the first push plate 31, slides in the opposite direction via the slider 52 under the restoring force of the spring 54, automatically resetting to its initial position. The clamping cavity becomes larger, allowing the processed waterproof sheet to be easily removed, completing one work cycle.
