Description
TECHNICAL FIELD
[0001] The utility model belongs to equipment maintenance technical field, more particularly in a kind of fixed tooling that avoids stamping die base displacement. BACKGROUND
[0002] J58K-1600 numerical control electric screw press is frame structure.As shown in Figure 1, upper and lower molds are respectively installed in upper and lower die base inside.Lower die base is installed on the workbench of the main body of equipment, and there is cylindrical key in the center position of lower die base bottom, which is positioned with workbench, and then fixedly connected with workbench through T-shaped nut.Upper die base is installed on the slider of equipment, and upper die base bottom is not positioned, and is only fixedly connected with workbench through T-shaped nut. Figure 1
[0003] The connection of upper and lower molds and upper and lower die bases is all gap adjustment through gasket, to ensure that upper and lower molds are centered, and then Y-axis direction of mold and die base is fixed through top pin, and X-axis direction of mold and die base is fixed through inclined iron.This fixing mode can ensure the relative position stability of mold and die base.The relative position of die base and mold does not change in long-term running state by measuring through the method of setting base point on die base.
[0004] The same method is used to set reference point on equipment workbench and slider respectively, and the displacement between die base and equipment in long-term continuous running state is observed.It is found that the relative position between die base and equipment will change randomly in long-term continuous running state of equipment, and the change of relative position is more frequent when stamping non-centrosymmetric product.Analysis of the connection mode of die base and equipment, a, die base and equipment are connected through T-shaped nut, and T-shaped nut and equipment are gap fitted, and bolt and die base are also gap fitted, which causes die base and equipment to be unable to form effective positioning through this structure.In long-term running, stamping vibration will cause relative displacement between die base and equipment, and this displacement seriously affects the stability of product.b, although there is cylindrical key positioning in the center of lower die base and equipment workbench, cylindrical key cannot constrain the generation of displacement, and does not play the role of positioning.
[0005] This die base structure can meet the normal production requirements during small-batch trial production of forgings. Because of the frequent die changes during small-batch trial production, adjustments are required after each change to ensure the upper and lower dies are aligned. However, during mass production of forgings, the lack of effective positioning for both the upper and lower die bases leads to random displacements of varying sizes over long-term operation. This causes deviations in the center of the upper and lower die bases, resulting in deviations in the final product's parting surface dimensions and producing defective products. Therefore, frequent adjustments to the die base and die alignment are necessary during production, severely impacting production continuity. This phenomenon is particularly pronounced when producing asymmetrical products.
[0006] Therefore, the solution to this problem is to apply pressure to the connection between the mold base and the equipment to effectively constrain the positioning and limit the relative displacement between the mold base and the equipment. Utility Model Content
[0007] The purpose of this invention is to overcome the problem that existing mold base structures, during long-term operation, will produce random displacements of different sizes, leading to deviations in the centers of the upper and lower mold bases, and ultimately resulting in deviations in the dimensions of the mold mating surface of the final product, producing defective products. This invention provides a fixing fixture to prevent displacement of the stamping mold base.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A fixing fixture for preventing stamping die seat displacement includes an upper die seat, several T-shaped locating keys, a cylindrical locating key, several T-shaped nuts, and a lower die seat. The upper die seat and the lower die seat are respectively provided with T-shaped grooves and circular grooves. The cylindrical locating keys are installed in the circular grooves, the T-shaped locating keys are installed in the T-shaped grooves, and the T-shaped nuts are locked in the T-shaped locating keys. The T-shaped nuts are fixedly connected to the worktable.
[0010] The T-slots are located at the four corner edges of the upper and lower mold bases.
[0011] The T-shaped positioning key includes a plurality of first T-shaped positioning keys and a plurality of second T-shaped positioning keys. The first T-shaped positioning keys are installed in the T-shaped groove of the upper mold base, and the second T-shaped positioning keys are installed in the T-shaped groove of the lower mold base.
[0012] The T-nut includes a plurality of first T-nuts and a plurality of second T-nuts, wherein the first T-nuts are engaged in the first T-position key and the second T-nuts are engaged in the second T-position key.
[0013] The dimensions of the first T-shaped locating key and the second T-shaped locating key are matched with their respective installed T-shaped slots.
[0014] The circular groove is located at the center of the upper mold base and the lower mold base.
[0015] The cylindrical positioning key includes a first cylindrical positioning key and a second cylindrical positioning key. The first cylindrical positioning key is installed in the circular groove of the upper mold base, and the second cylindrical positioning key is installed in the circular groove of the lower mold base.
[0016] The diameters of the first and second cylindrical locating keys match their respective circular grooves.
[0017] The location and number of the T-slots and circular slots are optimized according to the size and layout of the specific mold.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] This utility model provides a fixing fixture to prevent displacement of a stamping die seat, including an upper die seat, several T-shaped locating keys, a cylindrical locating key, several T-shaped nuts, and a lower die seat. T-slots and circular slots are respectively formed on the upper and lower die seats. The cylindrical locating keys are installed in the circular slots, the T-shaped locating keys are installed in the T-slots, and the T-shaped nuts are secured within the T-shaped locating keys. The T-shaped nuts are fixedly connected to the worktable. The securing installation of the T-shaped nuts and T-shaped locating keys effectively increases pressure and provides effective positioning constraints at the connection between the die seat and the equipment, effectively preventing relative displacement between the die seat and the equipment. This effectively reduces the frequency of product sampling inspections and the number of die adjustments during production. It achieves continuous and stable production of batch products while ensuring product quality.
[0020] Furthermore, T-slots are located at the four corner edges of the upper and lower mold bases, while circular slots are located at their centers. The T-slots at the corner edges ensure accurate alignment of the mold components during assembly, reducing deformation under stress and thus improving durability, assembly precision, and stability. The central position of the circular slots helps ensure stable rotation or movement of the workpiece during machining, thereby improving machining accuracy. This is particularly important for workpieces requiring high-precision machining. Attached Figure Description
