Description

Combined punch

Technical Field

The utility model relates to a punch, in particular to a combined punch.

Background

At present, through holes for plug connection formed in some pipes need to be arranged into a rectangular hole for rotation stopping and a round hole for supporting, so that the round hole is punched on one end face of the pipe and the pipe is punched by rotating 180 degrees, the punching positioning precision of the mode is poor, and the required processing time is long.

At present, chinese patent with publication number CN208758445U discloses a combined punch, which comprises a circular sleeve, wherein a square column is sleeved inside the circular sleeve, the outer end of the square column extends out from the lower end of the circular sleeve, and the square column is fixedly connected with the circular sleeve. The combined punch provided by the utility model can complete the punching work of the upper round and lower square holes at one time, is convenient to punch, has high precision, improves the production efficiency, has an adjusting function, and is compatible with the upper round and lower square holes with different sizes.

The above prior art solutions have the following drawbacks: the rectangular hole is punched at the position of the round hole before the round hole is punched, so that the round hole is difficult to form.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a combined punch so as to solve the problems in the prior art.

The technical purpose of the utility model is realized by the following technical scheme:

the utility model provides a combined punch, includes round bar and square bar, the vertical setting of round bar, the intermediate position at the top of round bar seted up with the rectangular hole that the square bar corresponds, square bar slidable mounting is in the rectangular hole, and the length of square bar is greater than the length of round bar, the top of the left end face of square bar and the top symmetry of the right-hand member face of square bar are provided with two rectangular channels, the top of rectangular hole be provided with the rectangle that the rectangular channel corresponds is protruding, just the length of rectangular channel is greater than the bellied length of rectangle.

In conclusion, the utility model has the following beneficial effects:

1. through the setting of square bar slidable mounting in the rectangular hole, promote earlier the round bar punching press and go out the round hole when punching a hole, then continue to go on to its punching press rectangular hole promoting the square bar.
