Description
Technical field
The utility model relates to the line pipe in a kind of industry, and particularly a kind of pipe end chamfered edge face at line pipe carries out the pipe end chamfered edge face imprinting apparatus of the line pipe of serial number impression.
Background technology
Oxygen, water, the oily carrier pipe of line-pipes in oil, gas industry.Enter 21st century, country has strengthened the construction to foundation engineering, West-East National Gas Transmission Project first phase, second phase go into operation in succession, add that global oil and gas industry is in gold period, as important equipment supplier, the line pipe manufacturing industry also obtains flourish, and is in all parts of the country newly-built and extended how tame HFW welded tube, UOE welded tube and spiral welded pipe tube mill.
Each root pipe of line pipe all can be given a serial number in manufacturing process, make things convenient for material flow tracing; The manufacturing process at that time that the while user in use also can trace this pipe according to this serial number is convenient to performance rating.At present generally on line pipe the mark serial number mainly be to paint etc. to be attached on inner surface of tube at pipe surfaces externally and internally jet printing journal number or with papery flowing water label.Because of wearing and tearing in natural environment weathering or the transportation easily cause the serial number of prior art mark to come off, inconvenient user uses tracking.
Fig. 1 is the schematic diagram of line pipe, as shown in the figure, the pipe end of line pipe 1 is provided with chamfered edge face 2, therefore, the user proposes to carry out the serial number impression on the pipe end chamfered edge face 2 of line pipe 1, change serial number mark mode, the method for stamping that adopts is directly to knock type matrix to pipe end chamfered edge face 2 with hammer at present, there is following shortcoming in this method for stamping: the one, dangerous, chamfered edge face smoother, the easy slippage of type matrix causes hammer easily to pound left-hand seat, and writing is unclear; The 2nd, rhythm is slow, influences the process of whole production.
The utility model content
For addressing the above problem, the utility model provides a kind of pipe end chamfered edge face imprinting apparatus of line pipe, can carry out the serial number impression quickly and easily on pipe end chamfered edge face.
For achieving the above object, the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model comprises circular arc matrix, compact heap, hold-down bolt and type matrix, the bottom of described circular arc matrix is welded with at least two alignment pins, include the contact-making surface that the pipe end chamfered edge face with line pipe is complementary on the described circular arc matrix, described circular arc matrix is provided with a plurality of type matrix through holes that pass the described type matrix of placement of described contact-making surface; Described compact heap is weldingly fixed on the top of described circular arc matrix; Described hold-down bolt passes described compact heap and is threaded with described compact heap.
Described alignment pin is two, is symmetrically distributed in the both sides, bottom of described circular arc matrix.
The outer ring of described alignment pin is coated with nylon jacket, and the end of described hold-down bolt is provided with nylon cushion.
The pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model can avoid hand security incident such as to be accidentally injured, and stamp work becomes convenient and swift, simultaneously, impresses more clear neat.By the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model, increased the security of operation, improved operating efficiency, and the impression better effects if.
Description of drawings
Fig. 1 is the schematic diagram of line pipe;
Fig. 2 is the schematic diagram (wherein not comprising type matrix) of the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view;
Fig. 4 is the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model and the connection diagram of line pipe.
The specific embodiment
Fig. 2 is the schematic diagram of the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model, and wherein type matrix does not show in the drawings; Fig. 3 be the A-A of Fig. 2 to cutaway view, Fig. 4 is the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model and the connection diagram of line pipe.Shown in Fig. 2～3, the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model comprises circular arc matrix 10, compact heap 20, hold-down bolt 21 and type matrix 30, the bottom of described circular arc matrix 10 is welded with at least two alignment pins 11, include the contact-making surface 13 that the pipe end chamfered edge face with line pipe 1 is complementary on the described circular arc matrix 10, described circular arc matrix 10 is provided with a plurality of type matrix through holes 14 that pass the described type matrix 30 of placement of described contact-making surface 13; Described compact heap 20 is weldingly fixed on the top of described circular arc matrix 10; Described hold-down bolt 21 passes described compact heap 20 and is threaded with described compact heap 20.
The alignment pin 11 of the bottom welding of described circular arc matrix 10 is preferably two, is symmetrically distributed in the both sides, bottom of described circular arc matrix 10, and described compact heap 20 preferably is fixed on circular arc matrix 10 upper middle position.By the hold-down bolt on the compact heap 20 21 and two alignment pins 11, the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model is fixed on the line pipe 1.
The pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model in use, at first the contact-making surface 13 that the pipe end chamfered edge face with line pipe 1 is complementary rests on the pipe end chamfered edge face of line pipe 1, band alignment pin 11 is close to the inwall at line pipe 1, compact heap 20 leans against the outer wall of line pipe, by tightening hold-down bolt 21, make hold-down bolt 21 compress the outer wall of line pipe 1, and alignment pin 11 compress the inwall of line pipe 1; Then the type matrix 30 that anti-raised character is arranged is injected in the type matrix through hole 14; Beat type matrix 30 successively with hammer again, make it on the chamfered edge face, form serial number; Pull down this device at last, finish this time serial number impression.
For preventing that alignment pin 11 from damaging line pipe 1 when the inwall with line pipe 1 contacts, the outer ring of described alignment pin 11 is coated with nylon jacket 12; Damage line pipe 1 when preventing that hold-down bolt 21 from compressing the outer wall of line pipe 1, the end of described hold-down bolt 21 is provided with nylon cushion 22.
The external diameter of described circular arc matrix 10 is preferably identical with the external diameter of line pipe, so that the pipe end chamfered edge face imprinting apparatus of line pipe of the present utility model can mate with line pipe 1 in use better.
The contact-making surface 13 of described circular arc matrix 10 contacts with the pipe end chamfered edge face of line pipe 1, insert type matrix 30 in a plurality of type matrix through holes 14 on the described circular arc matrix 10, like this, the distance between each character of serial number is consistent, and makes to impress the serial number neat appearance of coming out.And the position of type matrix 30 is fixed, and can not move when impression, makes that the character of impression is also more clear.
