Description
[technical field]
The utility model relates to the hole punched device of metal tubular workpieces, specifically relates to the hole punched device of a kind of metal straight pipe workpiece symmetry perforation.
[background technology]
In the process in metal straight pipe workpiece (hereinafter to be referred as workpiece) processing type hole, need radially to process at tube wall two holes of symmetry.Usually use drilling machine to divide secondary drilling just to finish, i.e. clamp, boring, 180 ° of clamp, borings again of turning of work piece, so drilling efficiency is low, wastes time and energy.Punch press punching mode appearred afterwards, namely earlier workpiece is positioned on the mould, drift moves downward and touches the pipe outer wall and stamp out a hole, again workpiece being rotated 180 ° locatees at mould again, then stamp out the hole with preceding hole symmetry, working (machining) efficiency increases though this processing technology is holed relatively, once only can go out a hole, and behind preceding hole, reorientating normal angle of arrival deviation in the process, there is the deficiency that is difficult to control two hole symmetries.
[utility model content]
In order to overcome the deficiency that existing processing type hole technology exists, the utility model provides a kind of hole punched device of metal straight pipe workpiece symmetry perforation that once can the punching out symmetrical holes, and it has high punching efficiency, characteristics that the punching precision is high.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
The hole punched device of metal straight pipe workpiece symmetry perforation, comprise workbench, the workpiece positioning component, back of the body riser and a left side, right oil cylinder seat, a left side, right oil cylinder seat and back of the body riser are installed on the workbench respectively, the workpiece positioning component is horizontal to be fixed on the back of the body riser, at least symmetry is embedded a pair of die on the sidewall of the left and right sides of workpiece positioning component, a described left side, right oil cylinder seat is separately installed with and comprises cylinder body, the left side of piston and piston rod, right hydraulic jack, a left side, the piston rod end of right hydraulic jack all is connected with the drift fixed cover that has a drift at least, on a left side, described drift matches with corresponding die under the driven in synchronism of right hydraulic jack.
In the bottom of above-mentioned workpiece positioning component and front end be respectively equipped with that waste material portals and catch.
Workpiece is inner after the punching can stay scrap metal by Disabled, and the power that shifts out from the workpiece positioning component by workpiece can make catch stay scrap metal to be transferred to waste material portals Disabled, and falls on the workbench, and scrap metal just can not continue to stay in workpiece.
The cross section of above-mentioned workpiece positioning component is rounded, and the appearance profile of this positioning component is used for being nested with round piece.
The cross section of above-mentioned workpiece positioning component roughly is square, and the appearance profile of this positioning component is applicable to and is nested with square cross.
The utlity model has following beneficial effect:
Since horizontally-mounted workpiece positioning component on the sidewall of the left and right sides at least symmetry be embedded a pair of die, right, the piston rod end of right hydraulic jack all is connected with the drift fixed cover that has a drift at least, can make and be set in workpiece on the workpiece positioning component, on the right side, carry out a punching press under the driven in synchronism of right hydraulic jack and can reach the symmetrical holes punching, need not need one-time positioning to stamp out a hole as prior art, stamp out symmetrical holes after again 180 ° of workpiece rotations being reorientated, therefore, the utility model is simple in structure, manufacturing procedure is few, the work efficiency height, machining accuracy is reliable, and cost is low.
