Abstract

The utility model discloses an internal mold tapping machine which comprises a bracket, a bearing arranged on the bracket and a tap chuck; wherein, a demountable extrusion tap is connected at the lower of the tap chuck; the straight-line movement of a punch is changed into spiral movement through a fixing plate, an active screw rod and an active nut, and then the spiral movement is transmitted to the tapping gear wheel through the active gear wheel, a small drive gear wheel and a large gear wheel; the tapping gear wheel drives the leading sleeve, and then the leading sleeve drives the distance-fixing screw rod and the extrusion tap to rotate and make synchronous movement with the punch during the cold punching to complete the tapping so that the punching and tapping can be once completed to improve the tapping efficiency and lower the cost and the non-chip tap extrusion is used to improve the service life of the extrusion tap.

Description

Tapping machine in the mould
One, technical field
The utility model belongs to mechanical driving device, is specifically related to tapping machine in a kind of mould.
Two, background technology
Cold-worked part is widely used in the production of industry and articles for daily use, and wherein some cold-worked part has screw need carry out tapping, and existing cold-worked part tapping is to establish the tapping program after this part punching is finished again one.The tapping method of usefulness mainly is to carry out tapping with manual tapping, bench drill tapping or special-purpose tapping machine at present.Said method all will to cold-worked part carry out secondary location and time-consuming, efficient is low, quality is unstable.
Three, summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, design tapping machine in a kind of mould, be loaded in the punch die and be synchronized with the movement, in cold stamping, finish tapping with punch die, utilize punch press to move up and down to convert circumference to rotatablely move, can reach the purpose of tapping.
For achieving the above object, the technical solution adopted in the utility model is: active screw rod moving up and down is meshed with rotating active nut, initiatively nut is assemblied on the support with bearing, initiatively the periphery of nut is fixed with driving gear, driving gear can directly connect the tapping gear, also but driving gear connects the tapping gear by the big small transmission gear that is meshed, the tapping gear is fixed on the outside of lead set, connect spacing screw rod moving up and down in the rotating lead set, the spacing screw rod is meshed with the spacing nut.
Another characteristics of the present utility model are: the spacing screw rod and the spacing nut that is meshed with it can move up and down in rotation, and whenever the rotate a circle distance that descends or rise of spacing screw rod equals to be threaded the pitch of screw.Initiatively the screw flight helical pitch equals initiatively screw rod external diameter girth.Be equipped with the fixing spring of contour screw the outside of the spacing screw rod and the spacing nut that is meshed with it, and the protection thread forming tap is not damaged when the punch press feeding is slipped up.
Four, description of drawings
Fig. 1 is the transverse cross-sectional view of the utility model structure
Five, the specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
With reference to Fig. 1, the present invention includes lower plate 1, middle plate 2, the support that upper plate 3 is formed and be assemblied in bearing 4 on the support, initiatively nut 5 usefulness bearings 4 are assemblied on the support, active screw rod 6 moving up and down is meshed with rotating active nut 5, driving gear 7 is meshed with active screw rod 6, and be fixed on the initiatively periphery of nut 5, driving gear 7 connects big travelling gear 16, big travelling gear 16 is meshed with small transmission gear 17, and small transmission gear 17 connects tapping gear 13, and tapping gear 13 is fixed on the outside of lead set 14, connect spacing screw rod 10 moving up and down in the rotating lead set 14, spacing screw rod 10 is meshed with spacing nut 11, and spacing screw rod 10 is fixed on the outside of tap chuck 12, and the below of tap chuck 12 connects removable thread forming tap 15.The spring of fixing with contour screw 89 is equipped with in the outside of spacing screw rod 10, spacing nut 11, and protection thread forming tap 15 is not damaged when the punch press feeding is slipped up.
Operation principle of the present utility model is as follows: by active screw rod 6, initiatively nut 5 becomes the rectilinear motion of punch press and rotatablely moves, process driving gear 7, small transmission gear 17 and big travelling gear 16 will rotatablely move and pass to tapping gear 13, tapping gear 13 drives lead set 14, lead set 14 drives 10 rotations of spacing screw rod, thereby thread forming tap 15 rotates the purpose that reaches tapping under the effect of spacing nut 11.Spacing screw rod 10, spacing nut 11 can move up and down in rotation, and whenever the rotate a circle distance that descends or rise of spacing screw rod 10 equals to be threaded the pitch of screw.Initiatively the lead of screw rod 6 equals initiatively screw rod 6 external diameter girths.In the outside of the spacing screw rod 10 and the spacing nut 11 that is meshed with it the spring of fixing with contour screw 89 is housed, protection thread forming tap 15 is not damaged when the punch press feeding is slipped up.
The utility model is finished punching press and tapping synchronously, has greatly improved the efficient of tapping, and the condition of visual workpiece is determined punch press speed, the highest 100SPM that adapts to, and can save personnel and machinery, and reduce the workpiece flow process, save power, raise the efficiency, reduce cost.Adopt the chipless thread forming tap, helix, fineness, pitch precision improve greatly, and the screw tap life-span can reach ten thousand screws of 20-40 generally speaking.
