Embodiment Construction

[0021] The specific content and working process of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] Figure 1 is a schematic diagram of a flexible mold for stamping an egg-box-shaped structure. The upper part of the figure is a pressing unit 1 equipped with an adjustable punch, the lower part is a fixed unit 2 equipped with an adjustable punch, and an edge-holding mechanism 3 for clamping the stamped sheet is installed between the two units. According to the shape of the egg box to be processed, first adjust the distance and position of the punches of the pressing unit 1 through the guide rail slider adjustment mechanism, so that the punches on the pressing unit 1 are arranged according to the egg box-shaped structure to be punched, and then according to The punch position of the pressing unit 1 is also adjusted by the guide rail slider adjustment mechanism to adjust the punch position of the ...

Abstract

The invention discloses a flexible die for punching forming of egg-box-shaped structures. The flexible device is mainly composed of a pressing unit, a fixing unit and an edge pressing mechanism, wherein adjustable punch pins are mounted on the upper portion of the pressing unit; adjustable punch pins are mounted on the lower portion of the fixing unit; the pressing unit is composed of a die base,the punches, punch pin mounting blocks and a guide rail and sliding block adjusting mechanism. The guide rail and sliding block adjusting mechanism is mainly composed of a punch pin base plate, guiderails, lock bolts, sliding blocks, punch pin slide rails, gaskets and guide rail base plates. The edge pressing mechanism is mainly composed of fixture mounting guide posts, fixture guide posts, a fixture, springs and spring mounting blocks. The flexibility variable thought is adopted for the overall design of the flexible device for punching forming of the egg-box-shaped structure. Under the action of two sets of the sliding blocks and the punch pin slide rails at a certain angle, fixed punch pins in a traditional punching forming device is changed to the adjustable punch pins, so that the required distance and angle are formed between the punch pins. Compared with the traditional punching forming device, the formability of the egg-box-shaped structures of different specifications and types is improved.

Description

technical field [0001] The invention discloses a flexible device for stamping and forming an egg-box structure, relates to a plastic processing equipment for stamping and forming an egg-box structure, and belongs to the field of mechanical engineering. Background technique [0002] The egg-box-shaped structure has the advantages of energy absorption, vibration isolation, and noise reduction, and has a broad application prospect. At present, the pitch of the punches of the existing egg-box-shaped structure forming dies is not adjustable, so the period of the egg-box-shaped structure is the same, and the type is relatively single. In practical applications, a variety of egg-box-shaped structures are required to meet the requirements of different conditions of use. Therefore, a mold that can adjust the structural cycle characteristics and quickly adjust the production model to achieve customized production is required. There is not yet the patented technology of an approximate...
