Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0016] Such as Figure 1-3 As shown, the hanger of a hanger-type workpiece of the present invention includes a connecting base 1, a bolt hole 8 is arranged on the top of the connecting base 1, and a first square opening 9 is opened at the lower end of the connecting base 1 along the front and rear direction. The left and right sides of the mouth 9 are provided with interlinked pin holes, and the upper end of the cross connection block 3 is located in the first square mouth 9 and is movably connected with the lower end of the connection base 1 through the front and rear rotary pins 2 . A certain distance is left between the top surface of the first square opening 9 and the top of the cross connection block 3 to facilitate the free ...

The invention relates to rapid stripping of a pull rod from a die in a hot riveting technology, in particular to a lifting tool for lifting a rod type workpiece. The lifting tool comprises a connecting base, wherein a bolt hole is formed in the top of the connecting base, the lower end of the connecting base is connected with a cross-shaped connecting block capable of rotating forwards and backwards, the lower end of the cross-shaped connecting block is connected with a cross beam capable of floating left and right, and lifting hooks are fixedly at the two ends of the cross beam. Through the design of the lifting hooks capable of swinging forwards and backwards and floating left and right, the rod which is connected with the die through the hot riveting technology can be lifted, the problem of the hot riveting technology that the rod type workpiece cannot be rapidly stripped from the die is solved, and the production efficiency is increased. The structure can meet the rapid and stable stripping requirement of the rod type riveting technology and has the advantages of simple and reasonable structure, low cost and high production efficiency.
Description
technical field [0001] The invention designs the rapid stripping of a thrust rod and a mold in a hot riveting process, and in particular relates to a hanger for a hanger-type workpiece. Background technique [0002] The production of truck thrust rods belongs to mass production. After the two ends of the thrust rod are riveted with the mold, due to thermal expansion and contraction, it is difficult to remove the thrust rod from the mold. Existing stripping methods include stripping by stripping springs, stripping mechanisms, or directly relying on crowbars. [0003] However, the prior art has the following defects: the stroke of the stripping spring is relatively short, and the material cannot be stripped by thermal riveting of the thrust rod; Low production efficiency. Contents of the invention [0004] The object of the present invention is to address the above-mentioned defects, and to provide a hanger for the boom-type workpiece that can quickly, smoothly and safely ...
