Abstract

The utility model discloses a flatten filter throat device, the throat device includes the last mould of throat lower mould and throat, and the throat lower mould passes through the bolt fastening on the bottom plate, and processing has the throat end die cavity of placeeing the filter and treating the throat end in the die body of throat lower mould, processing has interior die cavity of tungsten steel cover in the tungsten steel cover, the interior die cavity of last mould matches in tungsten steel cover, the interior die cavity of tungsten steel cover and the throat upper mould to through tungsten steel cover clamp plate dress on the throat is gone up the mould with the bolt-up, the material returned pole is packed into in last die cavity of last mould and the interior die cavity of tungsten steel cover. This technical scheme is to flattening the throat of filter through throat upper and lower mould, and this technical scheme not only can improve production efficiency, has still reduced manufacturing cost, has improved the competitiveness of enterprise simultaneously.

Description

Flattening filter necking device

Technical Field

The utility model relates to a throat device, specially adapted use when flattening filter throat.

Background

Traditional copper accessory flattens class filter so as figure 1, in order to guarantee to flatten the assembly size of end 10, need earlier flatten the end throat with tempering again and flatten, and the universal adoption is the instrument truck throat in the industry now, and the instrument truck throat is not only inefficiency, has the potential safety hazard (the instrument truck throat easily scratches the hand) moreover, how improves and flattens class filter throat efficiency, stops the potential safety hazard simultaneously, is the important problem of waiting to solve in an urgent need in industry.

Disclosure of Invention

The utility model aims to provide an end the potential safety hazard, improve production efficiency, reduction in production cost's a flatten filter throat device.

The utility model discloses a task is accomplished like this, its characterized in that: the necking device comprises a necking lower die and a necking upper die, the necking lower die is fixed on the bottom plate through a bolt, a necking end cavity for placing a flattening filter to be subjected to necking is processed in a die body of the necking lower die, a tungsten steel sleeve inner cavity is processed in a tungsten steel sleeve, the tungsten steel sleeve inner cavity is matched with an upper die inner cavity in the necking upper die, the tungsten steel sleeve inner cavity is installed on the necking upper die through a tungsten steel sleeve pressing plate and fastened through a bolt, and a material returning rod is installed in the upper die inner cavity and the tungsten steel sleeve inner cavity.

The necking upper die and the material returning rod are fixed on a sliding block of the punch, and the necking lower die and the bottom plate are fixed with a workbench of the punch through a pressing plate. The necking lower die and the necking upper die are installed on the same axis up and down.

The utility model discloses having following effect, this technical scheme is through the throat upper and lower mould to flattening the throat of filter, and this technical scheme not only can improve production efficiency, has still reduced manufacturing cost, has improved the competitiveness of enterprise simultaneously.

Drawings

FIG. 1 is a schematic view of a flattened end configuration of a flattening filter; FIG. 2 is a schematic view showing a structure of an end to be necked; fig. 3 is an exploded view of the present invention.

Description of the drawings:

1. the device comprises a bottom plate, 2, a necking lower die, 3, a necking die cavity, 4, a tungsten steel sleeve pressing plate, 5, a tungsten steel sleeve, 6, a tungsten steel sleeve inner die cavity, 7, an upper die inner die cavity, 8, a necking upper die, 9, a material returning rod, 10, a flattening end, 11, a to-be-necked end, 12 and a flattening filter.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The concrete embodiment is shown in fig. 3, the necking device comprises a necking lower die 2 and a necking upper die 8, the necking lower die is fixed on a bottom plate 1 through bolts, a necking end cavity 3 for placing a flattening filter 12 to be subjected to necking is arranged in a die body of the necking lower die 2, a necking end inner cavity 6 for placing a necking end 11 is arranged in a tungsten steel sleeve is arranged in the tungsten steel sleeve 5, the tungsten steel sleeve 5 and the tungsten steel sleeve inner cavity 6 are matched with an upper die inner cavity 7 in the necking upper die 8, the cavity and a material returning rod 9 belong to sliding fit, the cavity and the material returning rod are arranged on the necking upper die 8 through a tungsten steel sleeve pressing plate 4 and are fastened through bolts, and the material returning rod 9 is arranged in the upper die inner cavity 7 and the tungsten steel sleeve inner cavity 6.

The necking upper die 8 and the material returning rod are fixed on a sliding block of the punch, and the necking lower die and the bottom plate are fixed with a workbench of the punch through a pressing plate.

The necking lower die 2 and the necking upper die 8 are arranged on the same axis from top to bottom.

When flattening the filter to be necking, as shown in figure 2, a necking end of a flattening filter 12 is placed into a cavity 3 of a lower necking end, a necking end 11 is upward, a start-stop button of a punch is started, a foot switch is treaded, a slide block of the punch starts to drive an upper die assembly (a material returning rod 9, a necking upper die, a tungsten steel sleeve 5 and a tungsten steel sleeve pressing plate) to move downward, firstly, a cavity 6 in the tungsten steel sleeve in the upper die assembly starts to contact with the necking end of a product to be necked, the necking end enters the cavity 6 in the tungsten steel sleeve and pushes a material pushing rod 9 upwards, the slide block of the punch drives the upper die assembly to continue moving downward until reaching the necking length, the slide block of the punch drives the upper die assembly to start moving upward, the necking end and the cavity 6 in the tungsten steel sleeve are in interference fit, the upper die assembly can drive a necking product to move upward together, when the upper die assembly rises to a certain height, the material returning rod 9 can contact with a material, the upper die assembly continues to move upwards until the initial position is restored, the material returning rod 9 is pressed out by the punch material beating rod, and meanwhile, the material returning rod 9 ejects the filter product with the reduced opening out of the inner cavity 6 of the tungsten steel sleeve, and the filter product with the reduced opening is shown in figure 1.

This technical scheme adopts current punch press workstation and punch press slider and through throat upper and lower die structure has solved current flattening filter and has adopted the instrument truck throat, easily fish tail hand, the defect of inefficiency.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
