Description

Technical Field

[0001] This application relates to the field of punching technology, and in particular to a punching structure and punching equipment for solving product scratches. Background Technology

[0002] The external water-cutting production process consists of four parts: shape extrusion, LIP and skeleton punching, shape bending, and parts assembly. The material is mainly plastic. After extrusion, the cross-section has a deviation of ±0.5. When inserting the product into the positioning block, the gap cannot be too small, otherwise the cross-section of the LIP and skeleton will be directly affected by the quality and appearance of the product.

[0003] The original punching method, following a conventional structure, has the following defects: 1. When the mold is open, because the punching surface is only 0.47 mm away from the skeleton, the gap between the product and the upper cutter is small, making it difficult to insert; 2. When the upper cutter cuts the product and then retracts directly, the cutter will squeeze the punching surface again, scratching it and affecting the quality and appearance of the cross-section; 3. The squeezing when the upper cutter retracts will affect the size of the product. Utility Model Content

[0004] This application aims to solve one of the aforementioned technical problems in the prior art. Therefore, embodiments of this application provide a punching structure for solving product scratches.

[0005] This application also provides a punching device.

[0006] According to an embodiment of the first aspect of this application, a punching structure for solving product scratches is provided, including a lower die base; an upper die base; a lower cutter fixed to the lower die base; an upper cutter disposed on the lower die base, the upper cutter being configured to automatically reset; and a positioning member disposed on the lower die base for positioning the product, the positioning member being configured to automatically reset; wherein, during the movement of the upper die base toward the lower die base, the positioning member and the upper cutter are triggered sequentially, so that before punching, the positioning member moves toward the lower cutter, making the punching surface of the product positioned on the positioning member flush with the cutting surface of the lower cutter, and causing the upper cutter to move to cooperate with the lower cutter to complete the punching.

[0007] The aforementioned punching structure for resolving product scratches has at least the following beneficial effects: Before mold closing, the product is positioned by a positioning component. After the product is positioned, the upper and lower mold bases begin to close. During mold closing, the upper mold base first triggers the positioning component to move, causing the positioning component to move towards the lower cutter. Once the positioning component is in place, it is no longer driven by the upper mold base, ensuring that the surface of the product to be punched, which was positioned by the positioning component before punching, is flush with the cutting surface of the lower cutter. Then, the upper mold base triggers the upper cutter, causing it to move against the surface of the product to be punched until it cooperates with the lower cutter to complete the punching. This application optimizes the positioning component's structure, making it triggerable by the upper mold base. Before mold closing, this increases the distance between the product and the cutter, facilitating product loading and preventing surface scratches during loading, thus effectively improving punching quality.

[0008] According to the punching structure for solving product scratches as described in the first aspect of this application, the movement direction of the upper cutter is parallel to the movement direction of the upper die base, and the movement direction of the positioning member intersects with the movement direction of the upper die base.

[0009] According to the punching structure for solving product scratches as described in the first aspect embodiment of this application, the upper die base includes a first trigger and a second trigger. The first trigger is used to drive the upper cutter, and the second trigger is used to drive the positioning member. During the movement of the upper die base toward the lower die base, the second trigger first abuts against the positioning member.

[0010] According to the punching structure for solving product scratches as described in the first aspect of this application, the second triggering member drives the positioning member to move through a wedge structure.

[0011] According to the punching structure for solving product scratches according to the first aspect embodiment of this application, the wedge structure includes a first inclined surface and a second inclined surface that are parallel to each other. The first inclined surface is disposed on the second trigger member, and the second inclined surface is disposed on the positioning member. Before mold closing, the second inclined surface is on the movement path of the first inclined surface.

[0012] According to the punching structure for solving product scratches according to the first aspect of the present application, the positioning member includes a contouring part, a first guide part and a second guide part. The contouring part is used for positioning the product. The first guide part is disposed at the end of the contouring part and is used to guide the product to the contouring part. The second guide part is disposed above the contouring part and is used to make the product that arrives at the contouring part fit into the contouring part.

[0013] According to the punching structure for solving product scratches as described in the first aspect of this application, the number of second guide portions is not less than 2, and the second guide portion is a rotatable guide wheel.

Detailed Implementation

[0027] This section will describe in detail the specific embodiments of this application. Preferred embodiments of this application are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of this application, but they should not be construed as limiting the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0031] Reference Figure 1 The product in this application embodiment is an external water cutter 100, which includes a frame 110, an upper Lip 120 and a lower Lip 130. The part to be cut is the lower Lip 130, and the cutting surface is very close to the frame 110. Existing positioning structures are all fixed. Therefore, when loading and unloading products, the cutter is close to the frame 110, which may cause the cutter to scratch the surface of the frame 110.

[0032] To solve the above problems, such as Figures 2 to 7As shown, the punching structure for solving product scratches provided in this application includes a lower die holder 220, an upper die holder 210, a lower cutter 340, an upper cutter 320, and a positioning element 410.

[0033] The lower cutter 340 is fixed to the lower mold base 220.

[0034] The upper cutter 320 is mounted on the lower die base 220. The upper cutter 320 can move to engage with the lower cutter 340. The upper cutter 320 is configured to automatically reset, meaning it can automatically return to its original position after completing one punching operation. Normally, there is a gap between the upper cutter 320 and the lower cutter 340 to allow for product loading.

[0035] The positioning element 410 is disposed on the lower die base 220. The positioning element 410 is used for product positioning. The positioning element 410 is configured to be able to automatically reset. In this embodiment, the positioning element 410 is positioned at a certain distance from the lower cutter 340. Before punching, the positioning element 410 can move to be close to the lower cutter 340.

[0036] During the movement of the upper die holder 210 toward the lower die holder 220, the positioning member 410 and the upper cutter 320 are triggered in sequence, so that before punching, the positioning member 410 moves toward the lower cutter 340, so that the punching surface 101 of the product positioned on the positioning member 410 is flush with the cutting surface of the lower cutter 340, and the upper cutter 320 moves to cooperate with the lower cutter 340 to complete the punching.

[0037] Before mold closing, the product is positioned by the positioning component 410. After the product is positioned, the upper mold base 210 and the lower mold base 220 begin to close the mold. During the mold closing process, the upper mold base 210 first triggers the positioning component 410 to move, so that the positioning component 410 moves toward the lower cutter 340. When the positioning component 410 moves to the position, the positioning component 410 is no longer driven by the upper mold base 210, so that the punching surface 101 of the product positioned at the positioning component 410 before punching is flush with the cutting surface of the lower cutter 340. Then the upper mold base 210 triggers the upper cutter 320, so that the upper cutter 320 moves against the punching surface 101 of the product until it cooperates with the lower cutter 340 to complete the punching. After the punching is completed, the upper cutter 320 automatically resets, and the positioning component 410 also automatically resets to a position away from the cutter, which facilitates the unloading and loading of the product.

[0038] This application optimizes the setting structure of the positioning component 410, setting the positioning component 410 to be triggered by the upper mold base 210. Before the mold is closed, it increases the distance between the product and the cutter, which facilitates the loading of the product. Furthermore, there is no situation where the surface is scratched by the cutter during the loading process, which effectively improves the punching quality.

[0039] In some embodiments, the movement direction of the upper cutter 320 is parallel to the movement direction of the upper mold base 210, and the movement direction of the positioning member 410 intersects with the movement direction of the upper mold base 210.

[0040] In this embodiment, the upper mold base 210 moves vertically, while the positioning member 410 moves horizontally. The lower cutter 340 serves as the punching convergence point. During mold closing, the upper cutter 320 follows the upper mold base 210 to engage with the lower cutter 340 to complete the punching. The positioning member 410 is configured to convert the vertical movement of the upper mold base 210 into a horizontal movement, thus enabling the required actions to be completed without significant modifications to the equipment.

[0041] In some embodiments, such as Figures 2 to 6 As shown, the upper die holder 210 includes a first trigger 211 and a second trigger 212. The first trigger 211 drives the upper cutter 320, and the second trigger 212 drives the positioning member 410. During the movement of the upper die holder 210 toward the lower die holder 220, the second trigger 212 first abuts against the positioning member 410. This structure achieves sequential driving, ensuring that the cutting surface 101 of the product before punching can move to be flush with the cutting surface of the lower cutter 340.

[0042] In some embodiments, the second trigger 212 drives the positioning member 410 to move via a wedge structure. The wedge structure can convert the vertical movement of the upper mold base 210 into the horizontal movement of the positioning member 410.

[0043] In some specific embodiments, such as Figure 2 As shown, the wedge structure includes a first inclined surface 2121 and a second inclined surface 411 that are parallel to each other. The first inclined surface 2121 is disposed on the second trigger 212, and the second inclined surface 411 is disposed on the positioning element 410. Before mold closing, the second inclined surface 411 is on the movement path of the first inclined surface 2121, so that the first inclined surface 2121 and the second inclined surface 411 can cooperate to complete the displacement drive of the positioning element 410 before punching.

[0044] During the mold closing process, when the first inclined surface 2121 and the second inclined surface come into contact, the positioning component 410 drives the product's punching surface 101 to gradually approach the cutting surface of the lower cutter 340. When the first inclined surface 2121 and the second inclined surface change from contact to separation, the positioning component 410 no longer generates displacement and maintains its current position. That is, the product's punching surface 101 remains flat with the cutting surface of the lower cutter 340, ensuring the stability of the product positioning during the punching process.

[0045] After the punching is completed, the upper cutter 320 first separates from the lower cutter 340 and resets, and then the positioning component 410 resets and moves away from the lower cutter 340, which facilitates the loading and unloading of products.

[0046] In some embodiments, such as Figure 7 As shown, the positioning component 410 includes a contouring part, a first guide part 420, and a second guide part. The contouring part is used for product positioning, and the outer surface shape of the contouring part matches the shape of the product's position to be positioned, so as to achieve more accurate positioning. The first guide part 420 is disposed at the end of the contouring part and is used to guide the product to the contouring part, facilitating rapid product loading; the second guide part is disposed above the contouring part and is used to ensure that the product arriving at the contouring part fits against the contouring part, ensuring that the product's position to be positioned is in contact with the contouring part after it is in place.

[0047] like Figure 7 As shown, the number of second guide parts is not less than two, and the second guide part is a rotatable guide wheel 430. The guide wheel 430 can reduce the resistance during product loading and unloading, and effectively improve the loading and unloading speed.

[0048] In some embodiments, such as Figure 7 As shown, the positioning component 410 also includes a sensing unit, which is used for end positioning and positioning sensing of the product. The first guide portion 420 is located at the feeding end of the contouring portion, and the sensing unit is located at the other end of the contouring portion. The sensing unit can improve the accuracy of product positioning.

[0049] In some embodiments, the sensing unit includes a positioning block 441 and a proximity switch 442. Specifically, the positioning block 441 is configured to automatically reset. When the product is being loaded, as the positioning block 441 moves with the product to abut against the proximity switch 442, the proximity switch 442 sends a positioning signal to allow the mold closing operation to begin. The automatic reset of the positioning block 441 is achieved by a spring, and the proximity switch 442 can limit further movement of the positioning block.

[0050] like Figures 2 to 7 As shown, the punching structure for solving product scratches in this embodiment of the application also includes a mounting base 310. The mounting base 310 is provided with a slide groove for the upper cutter 320 to slide. A first return spring 350 is provided in the slide groove. During mold closing operation, the upper cutter 320 compresses the first return spring 350. After mold opening, the upper cutter 320 can automatically return to its original position under the action of the first return spring 350. The mounting base 310 is also provided with a limiting block 330 for preventing the upper cutter 320 from disengaging from the slide groove.

[0051] like Figures 2 to 7As shown, the punching structure for solving product scratches in this embodiment of the application also includes a stop block 360. The stop block 360 and the lower cutter 340 cooperate to form a motion groove for the positioning member 410 to slide. A second return spring 370 is provided in the motion groove. The second return spring 370 is located between the lower cutter 340 and the positioning member 410. When the mold is closed, the positioning member 410 compresses the second return spring 370. After the mold is opened, the positioning member 410 can automatically return to its original position under the action of the second return spring 370.

[0052] This application also provides a punching device, which includes the punching structure described above for solving product scratches.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
