Description

Technical Field

[0001] The utility model relates to the field of trimming dies, and more specifically, to a high-strength open-type connecting ring trimming die. Background Art

[0002] In mines, high-strength chains and scrapers are often used in combination to transport ores, and connecting rings are widely used for connecting high-strength chain links in mining equipment. In mining production, the use of scraper conveyors on the coal face shows that the breakage of connecting rings is one of the main factors affecting the operating efficiency of conveying machinery. The open-type connecting ring is a relatively widely used form of connecting ring at present, with the characteristics of high strength and convenient use;

[0003] After retrieval, the existing patent (publication number: CN207770720U) discloses a high-strength open-type connecting ring trimming die, which includes a base. A workbench is arranged on the base, and a trimming die is connected to the workbench by bolts. The trimming die is characterized in that: the trimming die includes a driving motor, an upper pressing plate, a lower pressing plate and a motor-driven lead screw. The driving motor is arranged on the upper surface of the upper pressing plate, and the upper pressing plate and the lower pressing plate are connected by the motor-driven lead screw to adjust the distance. A trimming die lower die is fixed on the upper surface of the lower pressing plate by bolts. A trimming die upper die is fixed on the lower surface of the upper pressing plate by bolts. A connecting ring is arranged between the trimming die lower die and the trimming die upper die, and a circle of flash is arranged along the central contour of the connecting ring. The trimming die upper die and the trimming die upper die of the present utility model are made of Cr12MoV material, and the hardness is HRC50-55 after heat treatment. The open connecting ring after removing the flash does not need to be polished and can directly enter the next process, improving production efficiency and saving costs.

[0004] After the existing connecting ring trimming die removes the flash, the removed flash needs to be taken out manually, which is somewhat dangerous, and the removed flash and the connecting ring are on the same plane, and they will not automatically separate from each other, so manual feeding is rather troublesome; at the same time, the cited patent document does not propose relevant solutions to solve the above problems;

[0005] Therefore, a high-strength open-type connecting ring trimming die is proposed for the above problems. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present utility model provides a high-strength open-type connecting ring trimming die to solve the problems raised in the above background art.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-strength open-type connecting ring trimming die, comprising a lower die base, mounting flanges welded to both sides of the lower die base, a blanking trough provided at the central position inside the lower die base, a lower die mounting seat provided inside the blanking trough, and a lower die core provided at the top end inside the lower die mounting seat;

[0008] An upper die seat is provided above the lower die seat, and an upper die core is embedded in the central position of the bottom of the upper die seat. An upper mold cavity is provided in the upper die core, and surfacing cutting edges are provided on the surrounding contours of the upper mold cavity.

[0009] Preferably, guide grooves are provided at the four corners of the top of the lower die base, and guide columns adapted to the guide grooves are correspondingly installed at the four corners of the bottom of the upper die base.

[0010] Preferably, the downward groove on the top of the lower mold core forms a lower mold cavity, and the lower mold cavity and the upper mold cavity are both configured to be composed of a C-shaped ring and two rectangles combined through a transition arc.

[0011] Preferably, the positions of the lower mold cavity and the upper mold cavity correspond to each other, and the internal depths of the lower mold cavity and the upper mold cavity are both half the thickness of the connecting ring to be trimmed.

[0012] Preferably, knife cuts are evenly formed on the top of the C-shaped ring of the lower mold cavity, and splitting knives are installed at positions on the bottom of the upper mold cavity corresponding to the positions of the knife cuts.

[0013] Preferably, the inner wall of the lower mold mounting seat is in contact with the outer wall of the lower mold core, and a bottom plate is integrally connected to the edge of the bottom end of the lower mold mounting seat, and a blanking opening is formed in the center of the bottom plate.

[0014] Preferably, spring buffer columns are evenly installed on the top of the base plate, and the tops of the spring buffer columns are connected to the bottom of the lower mold core. The lower mold core and the lower mold mounting seat form an elastic reset structure design through the spring buffer columns.

[0015] Technical effects and advantages of this utility model:

[0016] 1. Compared with the existing technology, the high-strength open-type connecting ring trimming die is provided with a blanking trough in the center of the lower die base. The lower die mounting base is arranged in the blanking trough, and its thickness is relatively narrow, so that the cut flash can fall automatically and be discharged from the bottom of the blanking trough, without manual cleaning of waste, which is more convenient to use and safer.

[0017] 2. Compared with the existing technology, the high-strength open-type connecting ring trimming die has an elastic reset structure design between the lower die core and the lower die mounting seat. Therefore, when trimming, the upper die seat is pressed down to first embed the lower die core into the lower die mounting seat, and then the trimming edge is welded to cut off the flash of the connecting ring. At the same time, the splitting knife can cut the entire circle of flash into multiple pieces, which is convenient for the blanking of the flash. Then the upper die seat moves upward, and the lower die core is reset under the elastic force of the spring buffer column, so that the connecting ring and the flash are further separated. The connecting ring can be hooked out through the opening of the lower die core using a material hook to complete the unloading. The overall operation is safer and the unloading is more convenient.

[0025] As attached Figure 1 The high-strength open-type connecting ring trimming die shown in the figure includes a lower die base 1, with mounting flanges 2 welded on both sides of the lower die base 1, and a blanking chute 6 is provided at the central position inside the lower die base 1, a lower die mounting base 7 is provided inside the blanking chute 6, and a lower die core 4 is provided at the top end of the lower die mounting base 7;

[0026] Above the lower die base 1, there is an upper die base 5, and at the central position of the bottom of the upper die base 5, an upper die core 11 is embedded. An upper die cavity 13 is arranged inside the upper die core 11, and surfacing trimming edges 12 are arranged at the peripheral contours of the upper die cavity 13.

[0027] Among them: during use, the connecting ring to be cut is placed in the lower die cavity 401 of the lower die core 4. The upper die base 5 is pressed down by the hydraulic cylinder, and the surfacing trimming edges 12 cut off the flash on the connecting ring. The cut-off flash can automatically fall off and be discharged from the bottom of the blanking chute 6, eliminating the need for manual waste cleaning, making it more convenient to use and safer.

[0028] Embodiment 2

[0029] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described below:

[0030] As a preferred implementation method, guide grooves 3 are opened at the four corners of the top of the lower die base 1, and guide posts 10 adapted to the guide grooves 3 are correspondingly installed at the four corners of the bottom of the upper die base 5; further, the design of the adapted guide posts 10 and guide grooves 3 makes the docking of the upper die base 5 and the lower die base 1 more accurate and the cutting accuracy higher.

[0031] As a preferred implementation method, a downward groove is formed at the top of the lower die core 4 to form a lower die cavity 401, and both the lower die cavity 401 and the upper die cavity 13 are formed by combining a C-shaped ring and two rectangles through transition arcs; further, the shape formed by combining the C-shaped ring and two rectangles through transition arcs fits the connecting ring exactly and can just fit the connecting ring, making the trimming more accurate.

[0032] As a preferred implementation method, the positions of the lower die cavity 401 and the upper die cavity 13 correspond to each other, and the internal depths of both the lower die cavity 401 and the upper die cavity 13 are half of the thickness of the connecting ring to be trimmed; further, the half-thickness design enables the lower die cavity 401 and the upper die cavity 13 to completely cover the connecting ring when they come into contact, making the connecting ring not easy to shake during cutting and facilitating the trimming operation of the flash.

[0033] As a preferred implementation method, knife cuttings 403 are evenly opened at the top of the C-shaped ring of the lower die cavity 401, and splitting knives 14 are installed at the positions corresponding to the knife cuttings 403 at the bottom of the upper die cavity 13; further, the splitting knives 14 can cut the entire circle of flash into multiple pieces, facilitating the blanking of the flash and making the design more reasonable.

[0034] As a preferred embodiment, the inner wall of the lower die mounting base 7 is fitted with the outer wall of the lower die core 4, and a bottom plate 8 is integrally connected to the edge position at the bottom end inside the lower die mounting base 7. A blanking opening 801 is formed in the center of the bottom plate 8. Further, the fitting design makes the lifting of the lower die core 4 more stable and not prone to tilting, making the flash cutting more accurate.

[0035] As a preferred embodiment, spring buffer columns 9 are evenly installed on the top of the bottom plate 8, and the tops of the spring buffer columns 9 are all connected to the bottom of the lower die core 4. The lower die core 4 and the lower die mounting base 7 constitute an elastic reset structure design through the spring buffer columns 9. Further, the elastic reset structure design enables the lower die core 4 to be reset under the elastic force of the spring buffer columns 9 after cutting, making the connecting ring further separated from the flash. At this time, a material hook can be used to hook out the connecting ring through the opening 402 of the lower die core 4 to complete the unloading. The overall operation is safer and the unloading is more convenient.

[0036] The working process of the present utility model is as follows:

[0037] During use, the connecting ring to be cut is placed in the lower die cavity 401 of the lower die core 4. The upper die base 5 is driven to move downward by a hydraulic cylinder. First, the lower die core 4 is embedded in the lower die mounting base 7, and then the surfacing cutting edge 12 cuts off the flash of the connecting ring. At the same time, the dividing knife 14 can cut the whole circle of flash into multiple pieces, and the flash automatically falls and is discharged from the bottom of the blanking groove 6. After cutting, the upper die base 5 moves upward, and the lower die core 4 can be reset under the elastic force of the spring buffer columns 9, making the connecting ring further separated from the flash. At this time, a material hook can be used to hook out the connecting ring through the opening 402 of the lower die core 4 to complete the unloading.

[0038] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
