Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic support component processing equipment, specifically to a processing mold for producing two parts in one mold for hydraulic supports. Background Technology

[0002] Hydraulic supports are the core support equipment for fully mechanized coal mining faces in underground coal mines. The top beam, as a key load-bearing component of the hydraulic support, directly affects the support performance of the hydraulic support due to its structural stability. The small curved plate of the top beam is an important connecting component in the assembly of the top beam, and it is necessary to ensure high forming accuracy and consistency.

[0003] Currently, the forming and processing of small curved plates for hydraulic support top beams mainly adopts two methods: one is traditional press forming, which requires the plate to be pressed first, and then the edge trimming operation. The short side of the small curved plate needs to be reserved for secondary processing, and the excess needs to be removed by secondary cutting. This not only involves cumbersome procedures but also wastes materials. At the same time, due to the difficulty in accurately controlling the forming parameters during press forming, the forming consistency of the small curved plate is poor, which makes it impossible to guarantee the welding continuity in the subsequent automatic welding process, further increasing production costs and reducing production efficiency.

[0004] Secondly, the mold is used for single-piece molding. Although this method solves the problem of poor consistency in the molding of small curved plates, reduces material waste and improves the processing efficiency of single pieces, during the production intensive period, that is, when the small curved plates of the hydraulic support top beam need to be mass-produced, a single set of molds can only process one workpiece at a time. The equipment production efficiency still cannot meet the needs of large-scale production, which restricts the overall production progress of the hydraulic support.

[0005] To address the issue of low equipment production efficiency in existing molding methods during intensive production, there is an urgent need to design a processing mold that can achieve simultaneous molding of multiple parts while ensuring molding accuracy. Utility Model Content

[0006] (I) Problems to be solved

[0007] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a processing mold for producing two small curved plates in a single processing, which can greatly improve the production efficiency of equipment during intensive production.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a processing mold for producing hydraulic supports with two parts in one mold, including an upper mold and a lower mold for cooperating to complete the forming of small curved plates of hydraulic supports;

[0010] The upper and lower molds are each provided with two sets of workpiece forming layers on their forming working surfaces for forming two types of hydraulic support small curved plates respectively.

[0011] The two sets of workpiece forming layers are respectively arranged at intervals along the length direction of the upper mold and the lower mold, and the interval is greater than or equal to 100mm.

[0012] As an improvement, the distance between the two sets of workpiece forming layers is 100mm-150mm.

[0013] As an improvement, the ratio of the bending radius to the thickness of the workpiece forming layer is >5.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows: By setting two workpiece forming layers on the mold, two small curved plates of the hydraulic support top beam can be formed simultaneously in a single processing. When production is intensive, the equipment production efficiency is doubled compared with the traditional mold single-piece forming, which effectively meets the needs of large-scale batch production. The preferred range of 100mm-150mm can effectively avoid the collision of the two workpieces or the mutual influence of forming stress during processing. Attached Figure Description
