Description
Technical Field
The utility model relates to the technical field of hub manufacturing, in particular to a device for online detecting the concentricity of a press machine.
Background
Along with the continuous promotion of forging aluminum alloy wheel hub metal utilization ratio, the input requirement of raw and other materials is more and more accurate, so require the enterprise must strictly monitor the deflection of blank in the blank manufacturing process to guarantee the quality of product. Forging aluminum alloy wheel hub belongs to solid flow forming, and equipment unbalance loading can lead to the inhomogeneous waste product that produces of product wall thickness among the deformation process, and when equipment produced the unbalance loading among the production process, operating personnel can't discern with the naked eye.
Disclosure of Invention
In order to solve the technical problems, the utility model provides the on-line detection press concentricity device which is convenient to operate and can dynamically detect the offset of the press workbench, thereby reducing the generation of waste products and lowering the production cost.
In order to realize the purpose, the utility model is realized by adopting the following technical scheme:
the device for detecting the concentricity of the press machine on line comprises an upper workbench and a lower workbench below the upper workbench, wherein an upper die is arranged on the upper workbench, a lower die is arranged on the lower workbench, the upper die corresponds to the lower die in the vertical position, the upper workbench is positioned on one side of the upper die and is fixedly provided with a downward detection pendant, and a standard block is fixedly arranged on the lower workbench below the lower workbench and corresponds to the detection pendant.
Preferably, a dial is arranged on the standard block.
Preferably, the detection pendant is installed on the upper workbench through a magnetic base.
Compared with the prior art, the embodiment of the utility model has the following beneficial effects: the device comprises an upper workbench, an upper die, a magnetic base and a detection pendant, wherein the upper workbench moves downwards, the upper die, the magnetic base and the detection pendant move synchronously, the upper workbench moves downwards to be in contact with raw materials, the upper workbench is stressed to start to deform until the upper die and the lower die are closed, a blank is completely formed, the direction and the offset of the detection pendant on a dial are observed at the moment, the range of the maximum number of turns is exceeded, and a forged product is directly scrapped.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
As shown in fig. 1 to 2, the device for online detecting concentricity of a press according to an embodiment of the present invention includes an upper table 1 and a lower table 8 below the upper table, an upper die 5 is mounted on the upper table 1, a lower die 7 is mounted on the lower table 8, the upper die 5 corresponds to the lower die 7 in the vertical direction, the press drives the upper table 1 to move downward so that the upper die 5 and the lower die 7 form a hub blank shape, the offset load of press equipment in a production process causes the tables of the press to be offset relatively, because the forged aluminum alloy wheel hub belongs to solid flow forming, the offset load of equipment in the deformation process can cause the uneven wall thickness of a product to generate waste, when the equipment is unbalanced-loaded in the production process, an operator cannot recognize the equipment by naked eyes, the detection pendant 3 is fixedly arranged on one side of the upper die 5 of the upper workbench 1, and the standard block 4 is fixed below the lower workbench 8 corresponding to the detection pendant 3; during initial state, will detect directly over 3 alignment standard block 4 of pendant, workstation 1 downstream is gone up in the press drive, goes up mould 5 and lower mould 7 shaping, detects 3 downstream of pendant and to contacting with standard block 4, observes and detects whether 3 skews of pendant, if take place the skew, the direction and the offset of inspection skew judge whether in qualified standard within range.
In the embodiment, the standard block 4 is provided with a dial 9; as shown in fig. 3, the dial 9 is a circular structure, concentric circular scale marks are milled on the dial, whether the pendant 3 deflects or not is detected during molding, if the pendant 3 deflects, the direction and the offset of the deflection are checked, for example, in the embodiment, if the offset of the pendant 3 exceeds the maximum circle of 2.5mm, a forged product is directly scrapped.
The detection pendant 3 is arranged on the upper workbench 1 through the magnetic base 2, the detection pendant 3 is fixed at the lower end of the magnetic base 2, the position of the magnetic base 2 can be adjusted at any time according to the position of the dial 9 on the standard block 4, the operation is convenient, the applicability of the device is enhanced, and the detection result is more accurate.
According to the device for detecting the concentricity of the press machine on line, disclosed by the embodiment of the utility model, when the device works, the press machine drives the upper workbench 1 to move downwards, the upper die 5, the magnetic base 2 and the detection pendant 3 synchronously move and move downwards until the upper die 5, the magnetic base 2 and the detection pendant 3 are contacted with the raw material 6, the upper workbench 1 starts to deform under stress until the upper die 5 and the lower die 7 are closed, when the blank 10 is completely formed, the detection pendant 3 moves downwards until the detection pendant 3 is contacted with the standard block 4, whether the detection pendant 3 is deviated or not is observed, and if the detection pendant is deviated, the deviation direction and the deviation amount of the pendant 3 on the dial 9 are detected, and whether the detection pendant is in a qualified standard range or not is judged.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
