Abstract

The utility model relates to a low die seat for connecting clamp die for terminal pressing joint machine. The whole group lower dies are supported by a spring which is in a circle slot of the seat bottom. A pressing bar is contained in a long slot of the lower die, and a front and a rear reel pieces of the terminal is pressed downwards by an upper die. Thus the reel pieces are respectively wrapped on the plastic cement jacketing and the bare terminal of the wire, and the whole group lower dies are subsided by a secondary stroke. The reel pieces behind a consolidation terminal are supported against by the tops of a pressing joint bar and the upper die, and the bare terminal of the wire are wrapped by the reel pieces tightly. Then the tightness of the terminal and the bare wire are increased. The combination of a special terminal and the wire can be achieved by an existing pressing joint machine with the structure of the utility model.

Description

Low die seat for connecting clamp die for terminal pressing joint machine

The die shoe structure-improved of the relevant continuous terminal press-connection machine of the utility model cassette mould refers to a kind of die shoe of meeting sb. at the airport as the cassette mold pressing of Fig. 9 and terminal crimping shown in Figure 10 that is applicable to especially.

Electronics industry prosperity now, it is meticulous to make the division of labor, so the industry of special manufacturing line terminal is arranged, its manufacture process is the banded plate that the sheet copper material is formed splicing ear through punching press, shift to the continuous terminal press-connection machine again and cooperate the artificial line operation of giving, in addition punching press and terminal and conductor compression jointing are become finished product.On the whole this continuous terminal press-connection machine all uses the cassette mould, its patrix and counterdie are all different according to various terminal, yet with Fig. 9 and terminal shown in Figure 10, all can't use general traditional terminal crimping connector, and must change the effect that is fastenedly connected that the special board that is suitable for this kind terminal just can be finished terminal and lead.Hence one can see that, for finishing such as Fig. 9 and terminal shown in Figure 10 the operation that is connected with lead, must improve existing press.For this reason, this creator repeatly after deliberation, study and revise repeatedly, finally be developed into structure-improved of the present utility model, the purpose of this utility model promptly provides a kind of die shoe that can utilize the modified model cassette mould of original terminal press, make it finish spiral with one-stop operation, the second flow path that connects airtight and needn't change board again, thus reduce work hours and cut down finished cost.

According to above-mentioned purpose, the die shoe structure-improved of continuous terminal press cassette mould of the present utility model, be spring to be set shore whole group counterdie in the base round recessed, and in the elongated slot of counterdie, be installed with depression bar, make patrix down during punching press, produce two sections strokes, thereby can finish the winding of terminal and bare wire automatically and connect airtight the twice program.

Existing conjunction with figs. describes the design feature of the utility model die shoe in detail, in the accompanying drawing:

Fig. 1 is the parts exploded perspective view of the utility model die shoe;

Fig. 2 is the schematic diagram on the press-connection machine of being installed on of the utility model die shoe;

Fig. 3 is the A-A generalized section of the utility model when first section stroke;

Fig. 4 is the B-B generalized section of the utility model die shoe when first section stroke;

Fig. 5 is the C-C generalized section of the utility model die shoe when first section stroke;

Fig. 6 is the A-A generalized section of the utility model die shoe when the latter end stroke;

Fig. 7 is the B-B generalized section of the utility model die shoe when the latter end stroke;

Fig. 8 is the C-C generalized section of the utility model die shoe when the latter end stroke;

The terminal stereogram that Fig. 9 is suitable for for the utility model die shoe;

Figure 10 is the connection status figure of terminal after the press-connection machine punching press through the utility model die shoe is housed and lead.

Each label implication is in the accompanying drawing:

(1) base (11) groove

(12) blind screwhole (2) spring

(3) at the bottom of crimping bar (31) bar

(32) screw (33) compression end

(4) locating piece (41) guide slot

(42) screw (5) counterdie

(51) skewed slot (52) square hole

(53) force-transmitting block (54) metallic channel

(6) the preceding volume mould of patrix (61)

(62) back volume mould (63) punching mould

(A) the preceding roll bending of terminal (A1)

(A3) bridge (A2) back roll bending

(A4) material hole

As seen from the figure, the die shoe structure of the utility model continuous terminal press-connection machine cassette mould is made up of base 1, spring 2, crimping bar 3, locating piece 4 and counterdie 5; Wherein

Base 1 is a platform, establishes a circular shallow grooves 11 on it, is provided with being installed with spring 2, so as to supporting whole group counterdie 5; Blind screwhole 12 is set on the groove 11, so that wear crimping bar 3 through bolt, and base and crimping bar are the loose fit positioning states.

Crimping bar 3 at the bottom of the mesa-shaped bar 31 one jiao perpendicularly establish a shaft-like compression end 33,31 are provided with screw 32 at the bottom of this bar, can wear the bolt location; This 33 tool obtuse angles of compression end diclinic end face is to increase the crimping tightness degree.

Locating piece 4 is rectangular block, and its side tool one T shape guide slot 41 plays the positioning and guiding effect when counterdie 5 upper and lower displacements; Guide slot 41 back are set up two screws 42 separately, are placed in base 1 so that wear bolt, and the tool positioning action.

5 of counterdies are combined by the several piece junior unit, and its combination rear side mask one skewed slot 51 unloads usefulness for waste material after the punching; There is a square hole 52 at the mould middle part, and the spatial accommodation of crimping bar 3 is provided; At the offside of skewed slot 51, the then outstanding force-transmitting block 53 that is provided with so as to transmitting the impulse force of patrix 6, sinks counterdie 5 and finishes and connect airtight the function of pressing terminal (A) and lead bare terminal end; A metallic channel 54 is established in counterdie 5 front sides, when lead places terminal (A) to go up, the lead of crimping is played positioning action.

As shown in Figure 2, the preceding volume mould 61 of its patrix 6 of assembling back and back volume mould 62 are positioned at counterdie 5 metallic channels 54 tops preceding roll bending A1 corresponding with terminal A and back roll bending A2 place in regular turn, its punching mould 63 then is positioned at the rear of back volume mould 62, that is the top of skewed slot 51, bridge A3 so as to punching terminal A, and make after bridge A3 cut off, fall along skewed slot 51.
