Abstract
The utility model discloses a dual-hole punching die, which comprises an upper die assembly and a lower die assembly, wherein, the upper die assembly is provided with two punches. Since the utility model adopts a double-punch structure, the processing efficiency is doubled, at the same time, the error of the relative position of two processed holes is reduced, the processing manner is simplified and facilitated, and the processing quality is easily guaranteed; and through the simple and convenient compress spacing and positioning, the request for utilization is met, the processing time is shortened, and the processing cost is reduced.
Description
Technical field
The utility model relates to a kind of punching die, particularly a kind of diplopore punching die.
Background technology
It is direct current trolley form that container terminal company field bridge oil changes electrical engineering, and variation has taken place the connecting rod version on its steel construction, has occurred the double flute hole on the structural member, can't satisfy the processing request of this structural member with existing punching machine mold.Because the slotted eye roughness requires to use gas cutting, if process this double flute hole with milling machine, processing cost and production efficiency can reduce greatly.
The utility model content
The utility model provides a kind of punching die that can be used in the processing diplopore for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of diplopore punching die, comprise mould assembly and lower mould assembly, and the described mould assembly of going up is provided with two drifts.
The described mould assembly of going up comprises upper bolster and described two drifts that are connected with described upper bolster by connecting plate.
Described lower mould assembly comprises die and the base plate affixed with described die, and described die has the profile that matches with work piece.
Be connected with the keeper and the locating part of work piece on the described base plate.
Advantage and the good effect that the utlity model has are: owing to adopted two punch structures, working (machining) efficiency is doubled, and has reduced the relative position error between two processed holes simultaneously, easy processing mode, and crudy is easy to guarantee; Compress spacing, location and not only satisfied instructions for use but also shortened process time by easy, reduced processing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model lower mould assembly;
Fig. 3 is the vertical view of Fig. 2.
Among the figure: 1, drift, 2, die, 3, upper bolster, 4, connecting plate, 5, workpiece, 6, base plate, 7, locating part, 8, keeper.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 3, a kind of diplopore punching die of the utility model, this mould is made up of last mould assembly and lower mould assembly two parts, and last mould assembly comprises upper bolster 3, connecting plate 4 and two drifts 1; Lower mould assembly comprises die 2 and base plate 6.Upper bolster 3 is used to connect mould assembly and punch press, and connecting plate 4 is used to connect upper bolster 3 and 1, two drift 1 of two drifts cooperates to come processing work 5 with die 2, and base plate 6 is used to connect die 2 and platen, is welded with keeper 8 and locating part 7 on the base plate 6.
Earlier two drifts 1 are connected with connecting plate 4 usefulness bolts during use, again connecting plate 4 are connected with upper bolster 3, promptly finish the mould assembly assembling.Die 2 and base plate 6 directly are connected with bolt by counterbore, base plate 6 are connected with platen again.
The utility model designs according to the dimensional requirement of the need machining hole on the drawing, and punch is designed to two drifts, and each drift had both had independently punch clearance cooperation, can guarantee the relative positional accuracies such as the depth of parallelism of two drift center lines again.The die that cooperates is the cuboid with channel-section steel profile, chamfering, counterbore, and channel-section steel was in the position of feeding motion vertical direction when the profile of channel-section steel defined punching, and chamfering is used for avoiding the fillet of channel-section steel profile, and counterbore is used for being connected of die and base plate.The base plate that is connected with die, at relevant position welding work pieces keeper and locating part, locating part is used for drift when withdrawing from, and keeps the location of workpiece not to be raised.
Workpiece to be machined 5 is by manually delivering on the die, and the front contacts with keeper 8, and two sides are spacing by die, above limited 7 the contact, get final product punching.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
