Abstract
The invention relates to a clamping device for punching of a curved surface of a circular tube. The clamping device comprises a workbench, a lower die holder and an upper die holder. The lower die holder is fixed on the workbench. The upper die holder arranged above the lower die holder is connected with the lower die holder through a positioning pin. A circular channel used for holding the circular tube and a positioning hole communicated with the circular channel used for holding the circular tube are formed between the upper die holder and the lower die holder. The center line of the positioning hole is identical to that of a punch mounted on a punching machine. A stand column is arranged on the workbench. A crossbeam is arranged on the stand column and is positioned above the upper die holder. A compacting device is arranged on the crossbeam. A handle used for rotating is arranged on the compacting device. The clamping device compacts the whole circular tube after wrapping the same, the circular tube does not deform during punching, and cutter sticking of punched holes is not caused, so that the percent of pass of processed products is increased effectively, working efficiency is improved, and labor intensity of operators is reduced.
Description
Technical field
The present invention relates to a kind of hole punched device, be specifically related to a kind of clamping device for punching on pipe curved surface.
Background technology
In the industry of some processing sports equipments, in the process of producing, often can on thin-wall pipes, hole.Traditional processing technology is in tubing, to place die, by drill bit, tubing is holed, and this technique can only be processed short tubing, and the longer pipe range of processing, the longest has more than 3 meters, just cannot use die in the mid portion punching of tubing.Adopt traditional technique to hole on pipe, because fluted drill can not cut on tubing curved surface simultaneously, processed tubing easily produces and rocks, chisel edge very easily forms " knife " after boring thoroughly, the hole qualification rate of boring on pipe is lower, and the time of this technological borehole is long, and boring a hole approximately needs 3-5 minute, operative employee's labour intensity is large, and operating efficiency is lower.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of clamping device for punching on pipe curved surface, this device can effectively clamp processed pipe, it can not be out of shape in punch process, effectively alleviate operative employee's labour intensity, improved operating efficiency.
Technical scheme of the present invention: a kind of clamping device for punching on pipe curved surface, this device comprises workbench, die shoe and upper bolster, die shoe is fixed on workbench, upper bolster is located at the top of die shoe, be connected with die shoe by alignment pin, between upper bolster and die shoe, be formed with the circular channel of placing pipe, and the locating hole being connected with the passage of placing pipe, the center line of locating hole is consistent with the center line that is arranged on the drift on punch press, described workbench is provided with column, column is provided with crossbeam, crossbeam is positioned at the top of upper bolster, crossbeam is provided with hold down gag, hold down gag is provided with the handle for rotating.
The mid portion of described upper bolster, die shoe is respectively and is provided with semicircular groove, and upper bolster and die shoe link together, and its positive mid portion is formed with the circular channel of placing pipe, and its side is formed with the locating hole being connected with circular channel.
Described crossbeam is provided with a screwed hole, and hold down gag is located in screwed hole.
Described hold down gag be positioned at upper bolster directly over.
Described locating hole is perpendicular to the passage of placing pipe.
The present invention compared with prior art has following beneficial effect: 1, this clamping device, by compressing after whole pipe parcel, makes it can not be out of shape in punch process; 2, the stamping-out point of drift breaks through after thin-walled, and punch die circumference (negative angle) participates in respectively die-cut, and a punching operation is completed, and the Kong Buhui rushing produces " knife " phenomenon, has effectively improved the qualification rate of product to be processed; 3, hold down gag adopts self-locking structure, can effectively clamp fast processed pipe; 4, hole of every punching approximately needs, about 3 seconds, effectively to have improved operating efficiency, has alleviated operative employee's labour intensity.

Detailed description of the invention
A kind of clamping device for punching on pipe curved surface, as shown in Figure 1 and Figure 2, this device comprises workbench 1, die shoe 2 and upper bolster 8, die shoe 2 is fixed on workbench 1, upper bolster 8 is located at the top of die shoe 2, be connected with die shoe 2 by alignment pin 4, between upper bolster 8 and die shoe 2, be formed with the circular channel of placing pipe, and the locating hole 11 being connected with the passage of placing pipe, the center line of locating hole 11 is consistent with the center line that is arranged on the drift 10 on punch press, and described locating hole 11 is perpendicular to the passage of placing pipe.Described workbench 1 is provided with column 3, and column 3 is provided with crossbeam 5, and crossbeam 5 is positioned at the top of upper bolster 8, and described crossbeam 5 is provided with a screwed hole, and hold down gag 6 is located in screwed hole, and hold down gag 6 is provided with the handle 7 for rotating.
The mid portion of described upper bolster 8, die shoe 2 is respectively and is provided with semicircular groove, upper bolster 8 links together with die shoe 2, its positive mid portion is formed with the circular channel of placing pipe, processed pipe 9 is placed in circular channel, by rotary handle 7, hold down gag 6 is moved vertically downward, withstand on upper bolster 8, thereby processed pipe 9 is clamped, it can not be out of shape in punch process, and its side is formed with the locating hole 11 being connected with circular channel.Start punch press, punch press drives drift swivel feeding, through locating hole, processed circle is carried out to punching, and rushing a hole probably needed for 3 seconds, and effective like this operating efficiency that improved, has alleviated operative employee's labour intensity.Rushed behind hole, turning handle 7, unclamps upper bolster 9, draws off pipe 9, completes a working cycles.
