Description

Filter shell stretching and blanking device

technical field

The invention relates to the manufacture of a filter for vehicles, in particular to a stretching and blanking device 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 object of the present invention is to overcome the above-mentioned shortcomings, and provide a filter shell stretching and blanking device with simple manufacturing process, good energy saving and environmental protection.

The present invention is realized through the following technical solutions: the stretching and blanking device for the filter housing includes an upper template and a lower template, a lower mold support and a pusher plate are installed on the lower template, and a mold is installed on the pusher plate. The blanking die and the blanking punch are sequentially installed on the mold frame through the die positioning plate, and the blanking punch is connected to the upper template through the blanking connection block; the blanking punch is connected to the upper template Blanking positioning blocks are also arranged between the templates.

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 is dropped. 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.

detailed description

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

As can be seen with reference to Fig. 1, the stretching and blanking device for the filter shell of the present invention comprises an upper template 1 and a lower template 14, on which a lower mold support 11 and a pusher plate 10 are mounted, on which the pusher plate 10 A mold base 9 is installed on the mold base 9, and a blanking die 7 and a blanking punch 6 are sequentially installed on the mold base 9 through a die positioning plate 8. The blanking punch 6 is connected to the upper template 1 through a blanking connection block 4. connected; a blanking positioning block 3 is also installed between the blanking punch 6 and the upper template 1 . It is used for easy exchange of molds and maintenance molds (including blanking punch 6, blanking die 7), more precise matching and material saving and consumption reduction, and blanking convexes of different sizes can be interchanged on a pair of mold bases Dies, blanking dies to produce products of different sizes. 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, Such a design facilitates the adjustment of the unloading force, and it can quickly remove the side material during yaw blanking, so that the side material will not stick to the blanking punch.

On the side (right side) of the lower mold support 11 and the pusher plate 10, and between the upper template 1 and the lower template 14, a multistage drawing die (comprising the first stage drawing die 21, the second stage Stretching die 22, three-stage drawing die 23, four-stage drawing die 24), shaping die 25 and trimming die 26, thereby completing the first-level, second-level, third-level, fourth-level, etc. of the filter housing successively Stage stretching and shaping (leveling), trimming processing procedures, and finally made into a finished filter housing. 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.

The working principle of the stretching and blanking device for the filter shell of the present invention is: under the action of the yaw feeder, there is no need for a special strip positioning device, and a guide column assembly is installed between the upper template 1 and the lower template 14 20. Its four ball-type guide columns are distributed in the two diagonal directions of the upper and lower rectangular templates. The guide column assembly has good rigidity and the guide is very stable. Therefore, the matching tolerance of the blanking punch 6 and the blanking die 7 can be adjusted to smoothly carry out the vertical motion blanking. The specific steps are: in the state where the blanking punch 6 and the blanking die 7 are separated, the first station of the strip of double-row raw materials is sent to the blanking die 7; When the punch 6 is pushed to the blanking die 7 to close the mold, it first contacts the blanking and stripping plate 5, because the spring force of the stripping spring assembly is arranged on the top, so the excessive deviation of the strip can be prevented. 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.
