Description
Technical Field
The invention belongs to the technical field of auxiliary facilities for knitting machining, and particularly relates to a needle plate riveting device.
Background
The aforementioned pin riveting device may also be referred to as a pin rolling device or a pin rolling device (hereinafter, the same applies) for plastically deforming the material at the tail of the pin to form local riveting with the insert, that is, to make the insert closely match with the pin.
As is known in the art, the needle plate (i.e., the so-called "needle plate body" or "needle bed body" hereinafter) is generally rectangular parallelepiped in shape and is machined from carbon steel. The upper plane of the needle plate is provided with a plurality of straight grooves (namely 'inserting grooves') with regular intervals, and the inserting sheets are embedded (namely inserted) in the straight grooves, and the positioning boss at the bottom of the inserting sheets is positioned by using joint filling glue after the front end steel wires are positioned. The gap formed between the inserting sheets is called a needle track, and the knitting needle moves up and down in the needle track under the action of external force such as a machine head so as to achieve the aim of the knitting needle to participate in knitting.
The aforesaid riveting of the tail of the needle plate is an effective measure for improving the close fit of the insert and the needle plate, and technical information related to the riveting device of the needle plate is visible in the published chinese patent literature, typically "a riveting device" as recommended in CN203636298U, the patent proposal can objectively embody the "advantage of being beneficial to replace time and labor-consuming manual operation, high efficiency and good operation effect" described in paragraph 0017 of the specification, but the following drawbacks are not difficult to find through reading the entire specification of the patent: firstly, because of unavoidable deflection of the needle plate itself and because of unavoidable errors during the processing of the needle plate and during the manufacture of the insert sheets, riveting the tail of the needle plate according to the teachings of the specification 00027 has a certain blindness, so that it is difficult or even impossible to obtain the same effect of tightly fitting all the insert sheets on the needle plate with the needle plate. Because when the pinch roller (namely, rolling cutter disc, hereinafter the same) of the riveting needle plate device corresponds to the deflection part (namely, concave part) of the needle plate, the pinch roller is similar to the tail part of the needle plate and is in non-contact condition, the effect of tightly matching the inserted sheet and the needle plate corresponding to the position cannot be reflected because the pinch roller cannot effectively rivet the tail part of the needle plate at the deflection part, otherwise, when the pinch roller corresponds to the arc arch of the tail part of the needle plate, namely, the bulge part, the needle plate is damaged because the excessive riveting pressure of the pinch roller to the position exists. Therefore, only if the riveting pressure applied by the pressing wheel to the tail part of the needle plate is consistent all the time, the degree of close fit between all the inserting sheets on the needle plate and the needle plate can be ensured to be the same, and the phenomenon of loose or mutually loose can not occur; secondly, because the hydraulic press is adopted, on one hand, the structure is complicated, and on the other hand, the space is saved due to large volume.

As shown in fig. 2 and 3, a cutter head connecting seat 543 is extended at the front end of the cutter head shaft 54, the cutter head connecting seat 543 has a cutter head groove 5431, and the cutter head 6 is pivoted to the cutter head connecting seat 543 at a position corresponding to the cutter head groove 5431 through a cutter head pin 61.
Referring to fig. 4, the above-mentioned needle plate 8 is shown in fig. 1 to 3, and the insert slot 81 on the needle plate 8 and the insert 82 (also commonly referred to as "needle plate insert" or "needle bed insert") inserted into the insert slot 81 are clearly shown in fig. 4, and in order to ensure that the insert 82 is tightly matched with the needle plate 8, the tail of the needle plate 8 is rolled by the needle plate riveting device (also referred to as "needle plate rolling device") according to the present invention, so that the tail of the needle plate 8, that is, the material of the notch portion of the insert slot 81, is plastically deformed to ensure that the insert 82 is tightly matched with the needle plate 8.
The process of rolling the tail of the needle plate 8 is as follows: the needle plate 8 with the inserted blades 82 is first placed on the needle plate support platform 11 by an on-line operator, and the needle plate 8 is held down by a set of needle plate positioning mechanisms 2 as described above by the applicant, see fig. 1 for a specific state. The rolling cutter head moving frame driving mechanism 3 is driven to work (under the instruction of the electric controller 13, such as the button operation on the electric controller 13 by an on-line operator), specifically: the rolling cutter moving frame driving motor 31 operates to drive the rolling cutter moving frame driving reduction box 32, the rolling cutter moving frame driving reduction box 33 is driven by the rolling cutter moving frame driving reduction box 32 because the rolling cutter moving frame driving screw 33 is in transmission connection with the rolling cutter moving frame driving reduction box shaft of the rolling cutter moving frame driving reduction box 32 through the screw shaft coupling 332, the rolling cutter moving frame driving screw 33 is driven by the rolling cutter moving frame 4 to be in transmission fit with the rolling cutter moving frame driving screw 33 through the screw nut 42, and the rolling cutter moving frame driving screw 33 drives the rolling cutter moving frame 4 to move together with the rolling cutter driving mechanism 5 which takes the rolling cutter moving frame 4 as a carrier, for example, the rolling cutter driving mechanism moves from the right end to the left end as shown in fig. 1, and the tail of a needle plate 8 is rolled by the rolling cutter 6 in the moving process.
The process of rolling the tail of the needle plate 8 by the cutter head 6 is as follows: under the instruction of the electric controller 13 (button operation on the electric controller 13 by an on-line operator), the rolling cutter driving motor 52 is operated, the rolling cutter driving reduction box 53 is driven by the rolling cutter driving motor, the rolling cutter driving reduction box shaft 531 drives the rolling cutter driving screw 55 to rotate through the coupler 551, the rolling cutter driving screw 55 drives the pressure plate 57 to move forward, the rolling cutter driving motor 52 and the rolling cutter driving reduction box 53 at the moment correspondingly move forward, the pressure plate 57 forces the rolling cutter pressure sensor 7 to move forward and pushes the rolling cutter shaft flange 542 of the rolling cutter shaft 54, and the rolling cutter shaft 54 is forced to move forward along with the sliding sleeve 58 towards the tail direction of the needle plate 8, so that the tail of the needle plate 8 is rolled by the rolling cutter 6. In the foregoing process, since the needle plate 8 does not have deflection, machining error, etc., when the force with which the rolling cutterhead 6 is in contact with the needle plate 8 is smaller than the process set value, then the electric controller 13 is fed back with a signal as the pressure sensed by the rolling cutterhead pressure sensor 7 is correspondingly decreased, and the electric controller 13 sends an operation command to the rolling cutterhead driving motor 52 to control the advancing and retreating degree of the rolling cutterhead 6, that is, to make the rolling cutterhead 6 obtain the desired constant rolling force to the tail of the needle plate 8, and vice versa. It can be seen that the rolling force of the rolling cutter 6 on the tail of the needle plate 8 is uniform due to the pressure sensor 7 of the rolling cutter, so that all the inserting pieces 82 inserted into the inserting piece grooves 81 of the needle plate 8 can be uniform with the close fitting effect of the needle plate 8, and the tightness or the loose tightness can not occur.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
