The utility model discloses a pipe side wall imprinting device which comprises a first die holder component, an imprinting mechanism and a second die holder component. Referring to fig. 1 and 2, the first die holder assembly of the pipe sidewall marking device according to the present utility model includes a first die plate 11 and a product positioning member 12, the first die plate 11 is fixedly disposed, the product positioning member 12 is disposed on an upper end surface of the first die plate 11, the product positioning member 12 is used for mounting a product, the product positioning member 12 is adapted to a receiving cavity of the product, and during marking, the product positioning member 12 can also provide support for the product, so as to avoid problems of sidewall dent deformation of the product, uneven marking depth due to shaking of the product due to stress, and the like.

The imprint mechanism includes an imprint assembly provided on the first template 11 and located on one side of the product positioning member 12, the imprint assembly being capable of being relatively close to or relatively far from the product positioning member 12, the imprint assembly including an imprint template 2111 and a first contact slope 2112, the imprint template 2111 being for imprinting upon contact with a product. The imprint template 2111 is conventional and will not be described in detail. Depending on the requirements, different imprinting assemblies can be selected, for example by means of air cylinders, or a combination of slides and slide rails, etc.

The second die holder assembly includes a second die plate 31, an imprint drive member 32, and an imprint limit member 33, the second die plate 31 being disposed above the first die plate 11, the second die plate 31 being capable of being relatively close to or remote from the first die plate 11. According to different requirements, different modes can be selected to realize the relative approaching or separating of the two, such as driving of an air cylinder, a motor screw rod and the like. Imprint driving member 32 is disposed on a lower end surface of second template 31, imprint driving member 32 being configured to abut first contact ramp 2112 and to drive the imprint assembly relatively close to product positioning member 12. The surface of imprinting drive member 32 contacting first contact ramp 2112 can be selectively configured differently, such as a ramp, curved surface, etc., according to different needs. Compared with the structure that a driving source is additionally arranged to drive the imprinting assembly to imprint, the structure can convert the descending power of the second template 31 into the imprinting assembly imprinting power, so that the space utilization rate is improved. An imprinting limit member 33 is provided on a lower end surface of the second template 31, the imprinting limit member 33 being for pressing a product at the time of imprinting. The product positioning component 12 is assisted in limiting and pressing the product through the imprinting limiting component 33, so that the product can be prevented from moving in the imprinting process, and the imprinting quality of the product is ensured.

When the pipe side wall engraving device is used, firstly, a product to be engraved is fixed on a product positioning component 12. Then, second template 31 is relatively close to first template 11 to drive imprint driving member 32 and imprint limiting member 33 to move with second template 31. Finally, after imprinting drive 32 contacts first contact ramp 2112 of the imprinting assembly, imprinting drive 32 drives imprinting assembly relatively close to the product such that imprinting stamp 2111 contacts the product; at the same time, the imprint limiting member 33 also compresses the product, preventing the product from moving during the imprinting process.

In some embodiments, the apparatus for imprinting a sidewall of a tube according to the present utility model further comprises an imprinting reset assembly for driving the imprinting assembly relatively far from the product positioning member 12. Depending on the requirements, different imprinting resetting assemblies can be selected, such as an additional arrangement of a driving source, such as a cylinder, for the imprinting assembly relatively far from the product positioning member 12.

Further, referring to fig. 7, in some embodiments of the apparatus for engraving a side wall of a pipe according to the present utility model, the engraving return assembly includes a first return block 221, a first elastic member 222 and a first return rod 223, the first return block 221 is fixedly disposed on the first mold plate 11, the first return rod 223 can move along its axial direction and is connected to the first return block 221, one end of the first return rod 223 is connected to the engraving assembly, the other end is provided with a first abutment member 224, the first elastic member 222 is disposed on the first return rod 223, and two ends of the first elastic member 222 respectively abut against the first abutment member 224 and the first return block 221. The imprinting resetting assembly formed by the first resetting block 221, the first elastic piece 222 and the first resetting rod 223 can effectively realize resetting driving of the imprinting assembly. Meanwhile, compared with a cylinder and the like which are used as a driving source, the seal-engraving resetting assembly with the structure can automatically realize resetting driving of the seal-engraving assembly after the limit of the seal-engraving driving part 32 is lost, and the efficiency is high.

Referring to FIG. 3, in some embodiments, the side wall imprinting apparatus of the present utility model includes an imprinting drive assembly 32 removably coupled to a second template 31. By being removable, imprinting drive assembly 32 is allowed to be individually replaced after a certain period of use without having to replace the entire second mold base assembly. Preferably, the fastener such as the selection bolt is provided so as to be detachable.

Referring to FIG. 3, the tube sidewall marking device of the present utility model, in some embodiments, the marking mechanism further includes an abutment assembly 23. Considering that although the compression limiting and supporting of the product are realized through the product positioning part 12 and the imprinting limiting part 33, a certain gap is always reserved between the accommodating cavity of the product and the product positioning part 12 so as to be convenient for installation, and the gap is not greatly influenced if the gap is relatively small; but if relatively large, it may still cause relative displacement of the product, affecting the quality of the imprint. Therefore, the abutting component 23 is further arranged to limit the product in an abutting way, so that the quality of the imprinting is ensured. The abutment assembly 23 is provided on the first die plate 11, and preferably the abutment assembly 23 is also detachably connected to the first die plate 11. The abutment assembly 23 is arranged on the other side of the product positioning member 12 where the imprinting assembly is arranged, so as to clamp the product and form a limit in cooperation with the opposite imprinting assembly.

The second die holder assembly further includes an abutment drive member 34, the abutment drive member 34 being adapted to abut the second contact ramp 232 and to bring the abutment assembly 23 relatively close to the product positioning member 12. The abutting driving member 34 is similar to the principle of the imprinting driving member 32, and can convert the descending power of the second template 31 into the power when the corresponding member to be driven moves, so as to improve the space utilization. Before the imprint template 2111 contacts a product mounted on the product positioning member 12, the abutment surface 231 abuts against the product mounted on the product positioning member 12, so that the product is limited and cannot be displaced, rocked, or the like before the imprint is started. Depending on the requirements, different ways can be chosen, for example by defining the initial position of both the imprinting assembly and the abutment assembly 23, or by defining the slope of both the first contact ramp 2112 and the second contact ramp 232, etc. Thereby ensuring that the abutting component 23 realizes the limit of the product before the imprinting component performs imprinting.

Referring to fig. 4, when the first contact inclined surface 341 abuts against the second contact inclined surface 232, the abutting driving member 34 drives the abutting assembly 23 relatively close to the product positioning member 12. The principle of this driving process is the same as that of imprinting drive assembly 32 driving the imprinting assembly to move. Referring to fig. 5, after the first contact slope 341 and the second contact slope 232 are separated, the buffer surface 342 abuts against the abutment member 23, and the abutment surface 231 abuts against the product mounted on the product positioning member 12. During this process, the abutment surface 231 has already brought into abutment with the product, while the abutment assembly 23 is no longer moving. At the same time, imprinting drive assembly 32 is still driving the imprinting assembly relatively close to the product. Preferably, the surface of the imprint driving member 32 contacting the first contact slope 2112 is provided as an imprint slope 321 to fit the first contact slope 2112 while ensuring the abutment effect. Referring to fig. 6, when the second contact slope 343 is in contact with the second contact slope 232, the imprint template 2111 is in contact with the product mounted on the product positioning member 12 to effect imprint. Meanwhile, under the action of the second abutting inclined surface 343, the abutting of the buffer surface 342 and the abutting component 23 can realize sufficient abutting of the abutting component 23, and movement of the abutting component 23 is avoided.
