Description

Stable conveying filter shell stretching and blanking mechanism

technical field

The invention relates to the manufacture of a filter for vehicles, in particular to a stretching and blanking mechanism for a filter shell applied to the filter manufacturing process.

Background technique

At present, a single-station drawing die is generally used for the stretching operation of the vehicle filter shell, which is stamped sequentially by multi-stage independent dies. A large number of human resources, and the problem of production positioning is not easy to solve. Without a unified and standard blanking table or blanking device, it is difficult to meet the requirements of mass production of high-precision stamping parts required by modern enterprises, and the economic benefits are not high.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a stable conveying type filter shell stretching and blanking mechanism with simple manufacturing process, good energy saving and environmental protection.

The present invention is realized through the following technical solutions: the stretching and blanking mechanism of the stable conveying filter housing includes an upper template and a lower template, a lower mold bracket and a pusher plate are installed on the lower template, and the pusher plate A mold base is installed on the mold base, and a blanking die and a blanking punch are sequentially installed on the mold base through a die positioning plate. The blanking punch is connected to the upper template through a blanking connection block, and the blanking punch A blanking positioning block is also installed between the die and the upper template; a multi-stage stretching die, a shaping die and a Trim mold.

After adopting the present invention, when the stamping machine pushes the blanking punch to the blanking die to close the mold, the first disc (to be stretched) on the strip material is dropped, and the first stage and the second stage of the filter housing can be completed successively. Multi-stage stretching, shaping (levelling), trimming, etc. It is easy to operate, easy to realize mechanization and automation, suitable for mass production of filter shell parts, can improve production efficiency, shorten processing cycle, ensure product quality and stamping accuracy, and greatly reduce labor costs and production costs, saving a lot of labor , reducing the defective rate.

Description of drawings

Fig. 1 is a schematic diagram of the installation structure of the present invention.

Detailed ways

The present invention will be described in further detail below with reference to the drawings and embodiments.

Referring to Fig. 1, it can be seen that the stretching and blanking mechanism of the stable conveying filter housing of the present invention includes an upper template 1 and a lower template 14, on which a lower mold support 11 and a pusher plate 10 are installed, and in the pusher A mold frame 9 is installed on the material flat plate 10, and a blanking die 7 and a blanking punch 6 are successively installed on the mold frame 9 through a die positioning plate 8, and the blanking punch 6 is connected to the The upper template 1 is connected, and a blanking positioning block 3 is also installed between the blanking punch 6 and the upper template 1, which is used for easy and convenient exchange of molds and maintenance molds (including blanking punch 6, blanking concave Die 7), more precise matching and material saving and consumption reduction, blanking punches and blanking dies of different sizes can be interchanged on a pair of mold bases to produce products of different sizes and specifications; on the lower mold support 11 and the side (right side) of the pushing plate 10, and between the upper template 1 and the lower template 14, a multi-stage stretching die (comprising the first-stage stretching die 21, the second-stage stretching die 22, the third-stage stretching die 22, and the Stretching die 23, four-stage stretching die 24), shaping die 25 and trimming die 26, thereby completing the multi-stage stretching and shaping of the filter shell successively such as one-stage, two-stage, three-stage, four-stage (whole flat), trimming process, and finally made into a finished filter shell. The transmission of the semi-finished filter shell is completed by the yaw feeder between each stamping (stretching) station, and the feeding height of each stamping (stretching) mold is equal.

On the die positioning plate 8 and at the side of the blanking die 7, a blanking and stripping plate 5 is installed, and the blanking and stripping plate 5 is connected with the upper template 1 through the stripping spring assembly 2, This design facilitates the adjustment of the unloading force. When the material is deflected, it can quickly remove the edge material, so that the edge material will not be attached to the blanking punch; between the upper template 1 and the lower template 14 The guide post assembly 20 is installed, and its four ball-type guide posts are distributed in the two diagonal directions of the rectangular upper and lower templates. The guide post assembly has good rigidity and very stable guidance, so it can guide the blanking punch 6, The matching tolerance of the blanking die 7 smoothly carries out vertical motion blanking up and down.

The working principle of the present invention is: under the action of the yaw feeder, no special strip positioning device is needed, and the specific steps are: in the state where the blanking punch 6 and the blanking die 7 are separated, firstly separate the double row The strip of raw material is sent to the blanking die 7 at the first station; then, when the stamping machine pushes the blanking punch 6 to the blanking die 7 to close the mold, it first contacts the blanking and stripping plate 5, because there are The spring force of the stripping spring assembly acts, so it can prevent the strip from being deflected too much. Then, the blade of the blanking punch 6 moves down to drop the first disc (to be stretched). When the stamping machine goes upward through the bottom dead center, the blanking and stripping plate 5 unloads the side material downwards under the action of the spring force. The pushing block of the yaw feeder pushes the wafer forward to the first stage drawing die 21 station when the stamping machine passes through the circumference of 110° to 145°. Then, when the stamping machine is from 150 degrees to the top dead center, the pushing block resets, and then, the second station of the strip material is blanked by the stretching blanking device of the filter housing and the stamping machine.
