Abstract

The utility model discloses a mold used for the curve form of a half-surrounded cable trough. The mold comprises a first upper mold and a first lower mold which are matched in dimensions, and a second upper mold and a second lower mold which are matched in dimensions; also comprises a mold handle; the upper end of the mold handle is connected with the stamping head of a stamping press; the lower end of the mold handle is connected with the first or the second upper mold; the first or second lower mold is mounted on the work top of the punch correspondingly. The utility model adopts the mode of combining a stamping press with a mold, and realizes the stamping forming of a half-surrounded cable trough by using quadric curved punching operations; can manufacture the half-surrounded cable troughs of special specifications, is operated simply, saves a great amount of machining work load, reduces production cost, and guarantees product quality.

Description

Be used for the curved mould of semi-surrounding cable trough

Technical field

The utility model mould belongs to plant equipment manufacturing technology field, relates to a kind of curved mould of semi-surrounding cable trough that is used for.

Background technology

In the manufacture process of plant equipment, electric part runs into a kind of with the curved irregular semi-surrounding cable trough that forms of 2mm steel plate, the rectangular tube of top open-ended can't be curved with folding brake, and employing is manually carried out curved, not only outward appearance is ugly, and size can't guarantee that waste time and energy, the semi-surrounding cable trough size of made differs, the outward appearance that is assembled together extreme difference directly influences the assembly quality of complete machine.

Summary of the invention

The purpose of this utility model provides a kind of curved mould of semi-surrounding cable trough that is used for, and solved that the finished size that the prior art manually-operated exists is nonstandard, assembly performance is poor, and the problem that wastes time and energy.

The technical scheme that the utility model adopted is, a kind of curved mould of semi-surrounding cable trough that is used for, comprise first patrix and first counterdie that size is supporting, and supporting second patrix and second counterdie of size, also comprise a die shank, the upper end of die shank is connected with the punch press drift, and when the lower end of die shank was connected with first patrix, the first counterdie correspondence was installed on the work top of punch press; When the lower end of die shank was connected with second patrix, the second counterdie correspondence was installed on the work top of punch press.

The beneficial effects of the utility model are, efficiently solve the curved problem of irregular semi-surrounding cable trough, enhance productivity, and reduce production costs, and have guaranteed drawing and instructions for use.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1 is the schematic perspective view that needs the semi-surrounding cable trough 1 of making, and it is wide to be A, and height is H, and the sealing surface breach is not wide is B, and material thickness is δ; Fig. 2 is the wide curved steel plate for the treatment of for C, and the semi-surrounding cable trough cross section that the numerical value of C equals among Fig. 1 launches length, i.e. C=2A+2H-4 δ-B.

With reference to Fig. 3, Fig. 6, the curved mould structure of semi-surrounding cable trough of the present utility model is, comprise first patrix 4 and first counterdie 3 that size is supporting, and supporting second patrix 6 and second counterdie 8 of size, also comprise a die shank 5, the upper end of die shank 5 is connected with the punch press drift, the lower end of die shank 5 and the first patrix 4(or second patrix 6) be connected the first counterdie 3(or second counterdie 8) correspondence is installed on the work top of punch press.

Fig. 4 is first patrix, 4 structural representations in the utility model, size G=D-2 δ-1 wherein; Fig. 5 is the structural representation of the curved steel plate 7 of for the first time curved intact resulting transition in back, size E=(A-B wherein)/2, D=A+2H-4 δ; Fig. 7 is second patrix, 6 structural representations in the utility model, size F=B-1 wherein, S=A-2 δ-1.

First patrix 4, first counterdie 3 and die shank 5 all adopt 45 steel, and local table is quenched after the machine-shaping, to increase access times.

The course of work of the utility model device is:

For the first time curved, with reference to Fig. 3, at first die shank 5 is fixed on 60 tons of punch presses, adopt the bolted mode to be connected first patrix 4 with die shank 5, then first counterdie 3 is fixed on the work top of punch press, makes the patrix 4 of winning, first counterdie, 3 cutting edges align cooperation.Required curved steel plate 2 is placed on first counterdie 3, adjust the position of steel plate 2 on first counterdie 3, operate punch press then, after treating that first patrix 4 contacts with first counterdie 3 and bends, steel plate 2 bendings become and are the curved steel plate 7 of transition, as shown in Figure 5, the semi-surrounding cable trough just completes the curved first time;

For the second time curved, with reference to Fig. 6, first patrix 4 and first counterdie 3 are taken off from punch press, change the outfit respectively and go up another set of second patrix 6 and second counterdie 8, the curved steel plate 7 of transition that the first time, bent gestalt obtained is placed on second counterdie 8, by above program punching operation one time again, just obtain needed semi-surrounding cable trough 1, after completing as shown in Figure 1.

The mode that the curved mould of the utility model adopts punch press to combine with mould, utilize the curved punching operation of secondary, realized the punch forming of semi-surrounding cable trough, can make the semi-surrounding cable trough of special requirement, simple, save a large amount of labor contents, reduce production costs, guaranteed product quality.
