Abstract
The utility model relates to a perforating top point and an ejector rod connection mechanism which are used during the production of seamless steel pipes. The utility model comprises a perforating top point and an ejector rod, wherein, a frustum-shaped raised part arranged on the rear end part of the perforating top point is matched with a frustum-shaped groove arranged on the front end of the ejector rod. The perforating top point of the utility model has the advantage of high structural strength, especially for metal ceramic perforating top points, and the utility model can normally work with difficult abruption during utilization.
Description
The perforating head and the push rod bindiny mechanism that use when the utility model relates to a kind of seamless steel tube production.
In the prior art, perforating head and the push rod bindiny mechanism that uses during general seamless steel tube production has following several: to small-bore perforation unit, adopt screw connection structure between perforating head and the push rod, do not have relative motion between perforating head and the push rod.To heavy caliber perforation unit, between perforating head and the push rod except having with screw connection structure, and the groove fit of more employing push rod head protuberance and perforating head rear end, what have therebetween also carries out axial location with marble spring, and can relatively rotate between perforating head and the push rod.Above-mentioned existing perforating head and push rod bindiny mechanism, its perforating head has screw or groove, thereby weakens the structural strength of perforating head, easily produces fracture, influences its service life.Especially to adopting the cermet perforating head,, and can not adopt above-mentioned various perforating head and push rod bindiny mechanism because of the easier generation fracture of fragility of its material.
The purpose of this utility model is to provide a kind of improved perforating head and push rod bindiny mechanism, improve the structural strength of perforating head, be achieved effective the connection each other and make the unlikely fracture damage of cermet perforating head operate as normal with push rod to adapt to the cermet perforating head.
For achieving the above object, the utility model adopts following technical proposals: the same perforating head and the push rod of including with prior art of the utility model.The rearward end that it is characterized in that perforating head has the taper type groove of taper type protuberance and push rod front end to mate.
On the above-mentioned perforating head taper type protuberance taper surface cross section being arranged is semicircular cannelure, to have on should the push rod of cannelure two be parallel to each other and with the pin-and-hole of push rod axis normal, in two pin-and-holes, insert pin key.Thereby make between perforating head and the push rod axially locking and can relatively rotate.
The utility model compared with prior art, have following conspicuous advantage: perforating head rearward end protuberance of the present utility model is connected with push rod front end groove coupling, the screw or the groove that then do not connect usefulness on the perforating head, do not weaken its structural strength, thereby its structural strength is more much bigger than perforating head structural strength of the prior art, is difficult for producing brittle fracture.Can relatively rotate between perforating head of the present utility model and the push rod, when then being difficult at work work because of perforating head and workpiece generation adhesion rupture.For the cermet perforating head, its material hardness is higher and fragility is bigger, then can adopt connecting elements of the present utility model, makes it in use can operate as normal and easy fracture not.
Accompanying drawing is the structural representation of an embodiment of the utility model.
An optimum implementation of the present utility model is: referring to accompanying drawing, this perforating head includes cermet perforating head 1 and metallic carrier rod 2 with push rod bindiny mechanism.Perforating head 1 is bullet-shaped, its rear portion has the taper type protuberance 6 and the taper type groove 5 of push rod 3 front ends to be complementary, it is semicircular cannelure 3 that the cross section is arranged on perforating head 1 taper type protuberance 6 taper surfaces, to have on should the push rod 2 of cannelure 3 two be parallel to each other and with the pin-and-hole 4 of push rod axis normal, in two pin-and-holes 4, insert pin key 7.Thereby make between perforating head 1 and the push rod 2 axially locking and can relatively rotate.
Claims (2)
