Description

Technical Field

[0001] This utility model relates to the field of mining chain technology, and in particular to a consistent mining butterfly chain weaving tooling mold. Background Technology

[0002] Mining chains are used as a supporting transmission medium in coal mine working face conveyors. They are widely used in various coal mine conveying equipment such as scraper conveyors and transfer conveyors, and are one of the most widely used spare parts in coal mine scraper conveyors.

[0003] Currently, there are two main types of mining chains: one is high-strength circular link chains for mining (such as...). Figure 1 The characteristic is that the vertical and horizontal rings are identical welded circular rings, conforming to the standard GB / T12718-2009 "High-strength Circular Link Chains for Mining"; another type is a high-strength compact chain for mining (such as...). Figure 2 The key feature is that the flat rings are welded round rings, and the vertical rings are flat extruded / forged rings, conforming to the standard MT / T929-2004 "High-strength Compact Chains for Mining". Compared to the simple method of alternating ring weaving of round ring chains, compact chain weaving requires bending and weaving using a special chain weaving combination mold. However, with the development of technology, chains such as those disclosed in invention patent application number US13143285 have emerged. The flat rings of this chain are approximately butterfly-shaped, and the vertical rings are flat. By modifying the shape of the flat rings, it can be adapted to the use of scrapers. However, due to the special structural form of butterfly chains, the above-mentioned chain weaving combination mold can only be used for compact chains and cannot be used for weaving butterfly chains.

[0030] Please refer to Figures 1 to 9 This utility model provides a mining butterfly chain weaving tooling mold, including a chain weaving mold 01, a top feeder 05, and an extrusion roller 06; the chain weaving mold 01 includes an upper mold 11 and a lower mold 12 that can be joined together; the upper end face of the upper mold 11 has a first groove 111, and the front end of the upper mold 11 has a first protrusion 112, the first protrusion 112 and the front end of the upper mold 11 forming a first arc-shaped part 113; the upper end face of the lower mold 12 has a second groove 121, and the front end of the lower mold 12 has a second protrusion 122, the second protrusion 122 and the front end of the lower mold 12 forming a second arc-shaped part 123; the end faces of the first protrusion 112 and the second protrusion 122 are in contact and fit together, so that the first arc-shaped part 113 and the second arc-shaped part 123 form an arc-shaped groove 03 for shaping the vertical ring forging material 30, while the first groove 111 and the second groove 121 form a groove 04 for positioning the butterfly flat ring 20. The ejector 05 is positioned directly opposite the groove 04 of the chain-making die 01, and is used to press the butterfly-shaped flat ring 20, which is inserted into the groove 04, tightly. The extrusion rollers 06 are symmetrically installed on both sides of the chain-making die 01, and are used to bend and shape the vertical ring forging 30.

[0031] The bottoms of the first arc-shaped portion 113 and the second arc-shaped portion 123 are higher in the middle and lower on both sides, so that the depth of the bottom of the arc-shaped groove 03 gradually increases from the middle to both sides. When shaping the vertical ring forging 30, it can ensure that the arc-shaped groove 03 can form a better fit and contact with the top of the vertical ring forging 30, thereby ensuring that the final bending, forming shape, and size of the vertical ring meet the requirements.

[0032] Among them, the openings on both sides of the arc-shaped groove 03 are larger than the opening in the middle.

[0033] The sides of the first groove 111 and the second groove 121 slope outward to form a supporting slope 07. The supporting slope 07 can support the butterfly-shaped flat ring 20.

[0034] Among them, the supporting slope 07 and the bottom side of the settling trough 04 form an arc-shaped edge 08, which can better fit with the end of the butterfly-shaped flat ring 20.

[0035] Both the upper mold 11 and the lower mold 12 have bolt fixing holes to facilitate installation and disassembly.

[0036] Both the upper mold 11 and the lower mold 12 have positioning platforms 10 at their bottoms.

[0037] The top feeder 05 has a positioning groove 51 at its end that is adapted to the width of the vertical ring forging 30.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
