Abstract

The utility model discloses a die for punching a base rotary joint. The die correspondingly comprises an upper dies (1) and a lower die (2) which are arranged correspondingly, wherein the upper die (1) sequentially comprises an upper die frame plate (10), an upper die base plate (12) and a stripper plate (14); the lower die sequentially comprises a lower die frame plate (16), a lower die base plate (18) and a lower plate (20); and a punch (22) is arranged in the stripper plate (14). The die is characterized in that a vertical rubbing rod (24) for removing hole wall burrs is arranged on the tail end of the upper die base plate (12), and a rotary drive device (26) for driving the rubbing rod (24) to rotate is installed on the top end of the rubbing rod (24). The die is simple in structure and is convenient to use.

Description

A kind of punching die of chassis adapter spare
Technical field
The utility model relates to a kind of punching die, relates in particular to a kind of punching die of chassis adapter spare.
Background technology
The hole punched device that uses at present mainly is divided into one-shot punch die and many punching dies, although the one-shot punch die is easy to use, but operating efficiency is lower, once can only rush a hole, therefore mostly use now many punching dies, once can made several holes, not only operating efficiency is higher, and punching quality is better, existing one-shot punch die and many punching dies mainly comprise template and punching pin, wherein are provided with one or more punching on the template, run through being provided with punching pin in the punching, although the punching die work of this kind structure is more stable, punching quality is better, but the hole wall burr that forms at sheet material is more, needs the artificial extra burr of removing hole wall, so not only bother, also increased the use cost of punching die.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of punching die of chassis adapter spare simple in structure, easy to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of punching die of chassis adapter spare, comprise the corresponding upper die and lower die that arrange, described patrix comprises patrix frame plate, upper die plate and stripper successively, described counterdie comprises counterdie frame plate, counterdie backing plate and lower bolster successively, be provided with punching pin in the described stripper, the end of described upper die plate is provided with a vertical friction-bar that is used for removing the hole wall burr, and the top of described friction-bar is equipped with one and is used for driving the drive unit that described friction-bar is rotated.
Described drive unit is motor.
The surface of described friction-bar is matsurface.
The initiating terminal of described lower bolster is equipped with a blowing device.
Compared with prior art, the beneficial effects of the utility model are:
Because the punching die of a kind of chassis adapter spare of the present utility model is provided with a vertical friction-bar that is used for removing the hole wall burr at the end of upper die plate, thereby can in punch process, just finish burr removal work, need not manually-operated, time saving and energy saving, and easy to operate, therefore the utility model is simple in structure, easy to use.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Among the figure: patrix 1, counterdie 2, patrix frame plate 10, upper die plate 12, stripper 14, counterdie frame plate 16, counterdie backing plate 18, lower bolster 20, punching pin 22, friction-bar 24, drive unit 26, blowing device 28.
The specific embodiment
Referring to shown in Figure 1, the punching die of a kind of chassis adapter spare of the present utility model, comprise corresponding patrix 1 and the counterdie 2 that arranges, wherein patrix 1 comprises patrix frame plate 10 successively, upper die plate 12 and stripper 14, counterdie 2 comprises counterdie frame plate 16 successively, counterdie backing plate 18 and lower bolster 20, in stripper 14, be provided with the punching pin 22 for punching, special feature of the present utility model is: the end of upper die plate 12 is provided with a vertical friction-bar 24 that is used for removing the hole wall burr, the surface of this friction-bar 24 is that matsurface and top are equipped with one for the drive unit 26 that drives its rotation, preferred this drive unit is motor, during use after punching pin 22 punchings are finished, the sheet material stepping runs to the below of friction-bar 24, friction-bar 24 is finished the removal work of hole wall burr in the down stroke of patrix 1, time saving and energy saving, and is effectively simple.
In addition, at the initiating terminal of lower bolster 20 blowing device 28 is installed, this blowing device 28 can be blown away the chip on lower bolster 20 surfaces timely, not only can keep lower bolster 20 cleaning surfaces, can also improve the punching precision.
In sum, the utility model is simple in structure, and is easy to use.
The above only is better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
