Description

A kind of device of punching on pipe fitting
The utility model relates to a kind of pipe fitting hole punched device.
Bore circular hole on pipe fitting, normally adopt drilling machine to finish, labour intensity is big, and production efficiency is low.If the shape in hole is an elliptical aperture, then need to process by milling machine, for erose hole, even adopt milling machine also can't time processing to finish, so not only production efficiency is low, and the production cost height.
The purpose of this utility model is the device of a kind of punching on pipe fitting of design, and this device is not only raised labour productivity, and reduces production costs, and can process the hole of different shape.
The purpose of this utility model is realized by the following technical programs:
The utility model is made up of upper die and lower die, lead, plug, Workpiece clamping device, base.Patrix is made up of drift, drift location-plate, cope match-plate pattern, last die shank, drift is located on the drift location-plate, and it is vertical with the drift location-plate, the drift location-plate is fixedlyed connected with cope match-plate pattern, establish die shank on the cope match-plate pattern, also establish fairlead on the cope match-plate pattern, lead is located on the base, and fairlead is enclosed within on the lead.Counterdie is fixed on the base, and Workpiece clamping device also is fixed on the base, and plug is hinged on the bearing on the base by pin, establish on the plug with counterdie on nib coaxial, with the hole of diameter, the hole on the plug, the nib on the counterdie are all coaxial with drift.
The drift shape of cross section is circular, square, oval, waist shape, and the shape of counterdie nib is consistent with the drift shape of cross section.
The plug shape of cross section is circular, square.
Workpiece clamping device is made up of workpiece positioning seat and eccentric clamping, and detent, the axis of detent and the plug axis coaxle that coincide with the workpiece profile established at the top of positioning seat.
Establish the plug guide holder on the base, the top of plug guide holder and counterdie is detent, the axis of detent and the plug axis coaxle that coincide with the workpiece profile.
Lead is circumferentially established oil groove, and lead is provided with two along the base diagonal.
The spring with plug jack-up is established in the plug below.
Workpiece principle of the present utility model is:
By last die shank patrix is connected with forcing press, shape according to hole shape, pipe fitting profile, punching in the pipe fitting is selected plug, clamping device, counterdie, drift, pipe fitting is inserted on the plug, rotating eccentric clamping clamps pipe fitting, drift is contained on the drift location-plate of patrix, start forcing press, patrix moves downward, and drift once dashes workpiece logical.If do not need through hole, need only regulate the patrix stroke by forcing press and can realize.
Technical characterstic of the present utility model and good effect:
1, can be on various tubing punching out square hole, circular hole, elliptical aperture, waist shape also, and one-shot forming.
2, labor strength reduces greatly, and production efficiency increases substantially, and energy efficient reduces cost, and product quality is guaranteed.
Below in conjunction with accompanying drawing the utility model is done further narration:
Fig. 1 is the structural representation of the present utility model of punching on rectangular tube, and 1 is to go up die shank, the 2nd, cope match-plate pattern, the 3rd, fairlead, the 4th, drift location-plate, the 5th, drift, the 6th, plug, the 7th, counterdie, the 8th, lead, the 9th, base, the 10th, attachment screw among the figure.
Fig. 2 is the vertical view after Fig. 1 removes patrix and lead, and 6 is plugs, the 7th among the figure, counterdie, the 9th, base, the 11st, mandrel holder, the 12nd, plug positioning seat, the 13rd, workpiece positioning seat.
Fig. 3 is the D-D cutaway view among Fig. 2, and 7 is counterdies, the 11st among the figure, mandrel holder, the 12nd, plug positioning seat, the 14th, spring, the 15th, nib.
Fig. 4 is the B-B cutaway view among Fig. 2, and 13 is workpiece positioning seats, the 16th among the figure, workpiece, the 17th, eccentric clamping, the 18th, screw.
As Fig. 1,2,3, shown in 4, this device is by the last die shank 1 that is located on the cope match-plate pattern 2, drift location-plate 4, fairlead 3, be fixed on the drift 5 on the drift location-plate 4, be located at the lead 8 on the base, counterdie 7, workpiece positioning seat 13, plug 6, mandrel holder 11, plug positioning seat 12 is formed, spring 14 is established in the below of plug 6, spring 14 is with plug 6 jack-up, be convenient to the operator and send into workpiece along plug 6, after workpiece puts plug 6, rotate eccentric clamping 6, workpiece is clamped, and last die shank 1 links to each other with forcing press, starts forcing press, patrix moves downward, and drift 5 is about to the rectangular tube workpiece towards wearing.Because this device is punching on rectangular tube workpiece 16, so the drift cross section in this device is circular, nib on plug 6 and the counterdie 7 is circle, and the detent on plug positioning seat 12, workpiece positioning seat 13 and the counterdie 7 is a rectangular recess, and the shape of cross section of plug 6 is rectangles.
At pipe upper punch circular hole, then only need to change plug into round mandrel, the plug positioning seat, counterdie and the detent that clamps on the bearing change circular trough into.
During towards square hole, mounting hole, elliptical aperture, only needing change drift into cross section is respectively square, waist shape, oval-shaped drift.
