Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 2 to 9, the necking mechanism of the air conditioner throttle valve comprises a workbench 1, wherein a limiting seat 2 for limiting blanks is arranged on the workbench 1, a plurality of groups of mechanical clamping jaws 3 for clamping the blanks in the limiting seat are arranged above the limiting seat 2, and each mechanical clamping jaw assembly 3 comprises a mechanical clamping jaw mounting seat 30, mechanical clamping jaws 31 which are fixedly arranged on the mechanical clamping jaw mounting seat 30 and correspond to the limiting seat in number, and a driving mechanism for driving the mechanical clamping jaw mounting seats to reciprocate. The mechanical jaws are of the same construction as the mechanical jaws of the prior art and the principle thereof will not be described in detail in this application.
A necking module 4 and an expanding module 5 are sequentially arranged on the workbench 1, a limiting seat 2 opposite to the necking module 4 comprises two limiting blocks 20, one limiting block 20 is driven by a limiting block driving mechanism 21, the necking module 4 comprises a necking module base 40, a translation cylinder 41 for pushing the necking module base to move is arranged on one side of the necking module base 40, a necking sleeve 42 is fixedly arranged on the necking module base 40, and a positioning thimble 44 is fixedly arranged in the necking sleeve 42; a necking space 200 for necking the blank is formed between the necking sleeve 42 and the positioning thimble 44, a pressing sleeve 45 is movably arranged outside the necking sleeve 42, and a pressing sleeve pushing mechanism 43 for pushing the pressing sleeve 45 to move is arranged on one side of the necking module base 40.
A plurality of strip-shaped grooves 42a extending axially along the necking sleeve are formed in the end portion of the necking sleeve 42, so that when the blank enters the necking space 200 formed between the necking sleeve 42 and the positioning thimble 44, the end portion of the necking sleeve 42 can deform along the strip-shaped grooves 42a to facilitate the blank to enter smoothly; when the blank enters the upper necking space, the pressing sleeve pushing mechanism 43 pushes the pressing sleeve 45, so that the pressing sleeve 45 extrudes the necking sleeve 42, and the blank in the necking space 200 is extruded out of the cylinder part with the reduced aperture.
When the necking module 4 operates, firstly, the limiting block driving mechanism 21 drives one limiting block 20 to approach to the other limiting block, so that the part of the blank needing to be necked is exposed, then the translation cylinder 41 acts to push the necking module base 40 to translate, the necking module base 40 drives a necking sleeve and a positioning thimble 44 fixed with the necking module base to press the blank, firstly, the positioning thimble 44 is pressed into the blank to further press the filter screen to a preset position, and meanwhile, the blank can be limited; then the pressing sleeve pushing mechanism 43 pushes the pressing sleeve 45 to translate towards the position of the necking sleeve 42, so that the blank is pressed out of the cylinder part with the reduced aperture in the necking space 200.
After the blank is pressed out of the cylinder part with the reduced aperture in the necking module 4, the blank is transferred from the limiting seat corresponding to the necking module 4 to the limiting seat 2 corresponding to the expanding module 5 through the mechanical clamping jaw of the mechanical clamping jaw assembly 3.
Because it is difficult to extrude the cylinder part with smaller aperture through the way of necking in practice, the actual aperture of the cylinder part of the blank and the actual aperture of the cylinder part in the presetting are smaller in the actual necking module 7, and then the blank is expanded to the preset aperture through the expanding module 5. Specifically, the opening expanding module 5 includes an opening expanding thimble 50 and a third translation cylinder 51 for pushing the opening expanding thimble 50, where the opening expanding thimble 50 has a diameter the same as the required diameter of the opening to be reduced, and the third translation cylinder 51 pushes the opening expanding thimble 50 to push the blank, so as to expand the cylindrical portion of the blank to a preset aperture.
The limiting block 20 of the limiting seat 2 is provided with a mounting groove 22, an insert 24 is fixedly arranged in the mounting groove 22 through a buckle plate 23, and an opening shape matched with the shape of the blank is formed on the insert 24. In this configuration, different types of inserts 24 may be replaced for different types of blanks.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be appreciated by persons skilled in the art that the present invention is not limited by the embodiments described above. The foregoing embodiments and descriptions of the present invention have been presented only for the purpose of illustrating the principles of the invention and are not intended to be exhaustive or to limit the invention to the precise forms disclosed.
