Abstract

The utility model relates to a pressing die for a plurality of single curved surface bulletproof breast plates, each of which is formed by four combined outer supports and a plurality of combined dies; wherein, each combined outer support comprises a plurality of groups of upper and lower guide sleeves and a plurality of retaining nuts, the upper guide sleeves are arranged in the lower guide sleeves and can slide downwards, and a plurality of right-angled die fixing forks connected with the retaining nuts into a whole can fix one angle of the corresponding die. The pressing die has the advantages of overcoming the defects in the prior pressing die, such as larger time and energy consumption for pressing a single product, lower work efficiency, shorter service life and higher production costs, press-forming a plurality of single-curved surface bulletproof breast plates, saving energy and improving the efficiency, and lowering the production costs.

Description

Polylith single-curved surface bulletproof chest-protector plate compacting tool set

Technical field

The utility model belongs to the mechanical compaction mould, particularly a kind of polylith single-curved surface bulletproof chest-protector plate compacting tool set.

Background technology

Bulletproof chest-protector plate is mainly used in a kind of personal safe protection's product in army and the public front anti-terrorism protrusion-dispelling emergency event.Present single-curved surface bulletproof chest-protector plate generally adopts the monolithic compacting, and work efficiency is low, and time-consuming power consumption has increased the compacting frequency, has reduced the press life-span, has also increased production cost.

The utility model content

At the deficiency of above-mentioned single stamped, the purpose of this utility model provides a kind of polylith single-curved surface bulletproof chest-protector plate compacting tool set, can once suppress polylith single-curved surface bulletproof chest-protector plate.

The technical solution of the utility model is: 1. 4 outer pillars of combination will make up compacting tool set and be fixed on the middle part; 2. the outer pillar of every combination and upper and lower guide pin bushing and several hold-down nut that be pagoda shape interrelated by several covers constitutes, and the upper guide bush in the next guide pin bushing combination is again the following guide pin bushing in the last guide pin bushing combination; 3. make up compacting tool set and be made up of the upper, middle and lower mould, every mould is cube, and mold simultaneously is convex, and middle mould is a protruding spill, and bed die simultaneously is spill; Leave the gap that adheres to specification between two moulds.

The utility model has the advantages that: 1. can once suppress polylith single-curved surface bulletproof chest-protector plate, improve efficient, save the energy, reduce production cost; 2. reasonable in design, simple in structure being suitable for has certain application value.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is 1 a cover upper and lower guide pin bushing structure partial enlarged drawing (circle sign place among Fig. 1) in the built-up pillar (1);

Fig. 3 is the A-A cutaway view of Fig. 2.

The specific embodiment

Now in conjunction with the accompanying drawings, and be example, technology contents of the present utility model be further described with 5 single-curved surface bulletproof chest-protector plates of one-shot forming:

1,4 built-up pillars (1) will be fixed on the middle part by the combination compacting tool set that all leaves the gap that adheres to specification between the bed die (7) of the mold (9) of one side convex, 4 pieces one protruding one recessed middle moulds (8) and one side spill and per two moulds.

2, every built-up pillar (1) by 5 covers interrelated and following guide pin bushing (2), upper guide bush (3) and 6 hold-down nuts (4) that be pagoda shape form; Upper guide bush (3) places down in the guide pin bushing (2) and can move down, and a upper guide bush (3) is again the following guide pin bushing of last guide pin bushing combination, by that analogy; Connecting rod (5) is connected as a single entity hold-down nut (4) and square mould fixation fork (6); Hold-down nut (4) and following guide pin bushing (2) are fastening, and square mould fixation fork (6) is fixed a jiao of corresponding mould.

Operation principle of the present utility model is: the utility model is placed in the press, simultaneously single-curved surface bulletproof chest-protector plate to be pressed is placed the adjacent molds gap, when press piston (11) drives press walking beam (10) when moving downward, produce 2 courses of work:

1, upper guide bush (3) in following guide pin bushing (2) to lower slider;

2, mold (9) and 4 middle moulds (8) are depressed simultaneously, suppress single-curved surface bulletproof chest-protector plate to be pressed respectively.

Claims

1, a kind of polylith single-curved surface bulletproof chest-protector plate compacting tool set is characterized in that:

1. in the middle part of the bed die (7) of mold (9), several one protruding one recessed middle moulds (8) and the one side spill that 4 built-up pillars (1) will the one side convex and combination compacting tool set that per two moulds leave the gap are fixed on;

2. every built-up pillar (1) and following guide pin bushing (2), upper guide bush (3) and several hold-down nut (4) that be pagoda shape interrelated by several covers formed; Upper guide bush (3) places down in the guide pin bushing (2) and can move down, and a upper guide bush (3) is again the following guide pin bushing of last guide pin bushing combination, by that analogy; Connecting rod (5) is connected as a single entity hold-down nut (4) and square mould fixation fork (6); Hold-down nut (4) and following guide pin bushing (2) are fastening, and square mould fixation fork (6) is fixed a jiao of corresponding mould.
