Technical Field
[0001] The utility model relates to the technical field of circular knitting machines, in particular to a highly stable and wear-resistant circular knitting machine casting. Background Art
[0002] A circular knitting machine is a type of knitting machine with a cylindrical or disc-shaped needle bed, primarily used to produce cylindrical weft-knitted fabrics. Circular knitting machine castings refer to cast parts used in circular knitting machines, specifically for their assembly and operation. Casting is the process of melting metal into a liquid state, pouring it into a pre-prepared mold, and then cooling and solidifying it to form a solid metal part of the desired shape and size. Circular knitting machine castings are triangular castings that are used to move the textile needles in conjunction with the circular knitting machine.
[0003] When the casting is used in conjunction with the circular knitting machine, the casting is an integrated structure and there is no internal stabilization mechanism to support the high stability of the casting. This will cause the casting to be easily bent and deformed after long-term use, which will affect the stable textile manufacturing use of the circular knitting machine in the later stage and shorten the service life of the casting.
[0004] In order to overcome the above-mentioned defects, prior art 1 (application number CN202223576520.6, Chinese patent application date 2022-12-30) is a high-stability water pump casting. After the base is fixed in a suitable position by fastening bolts, the elastic force of the fixing spring is used to make the sliding block slide and drive the anti-loosening rod to slide back to its original position, thereby limiting and tightening the top of the fastening bolt to avoid possible loosening of the fastening bolt thread, thereby ensuring the stable and continuous operation of the water pump triangular casting and improving its practicality.
[0005] Therefore, we proposed that high-stability and wear-resistant circular knitting machine castings can solve the above problems well. Utility Model Content
[0006] The purpose of the utility model is to provide a highly stable and wear-resistant circular knitting machine casting to solve the problem raised in the above-mentioned background technology that in the current market, when the casting is used in conjunction with the circular knitting machine production, since the casting is an integrated structure, there is no stabilizing mechanism inside it to support the high stability of the casting, which will cause the casting to be prone to bending and deformation after long-term use, thereby affecting the later stable textile manufacturing use of the circular knitting machine and shortening the service life of the casting.
[0007] To achieve the above object, the utility model provides the following technical solution: a highly stable and wear-resistant circular knitting machine casting, comprising a triangular casting and a positioning block, wherein the positioning block is positioned and installed on the rear side of the left end of the triangular casting, and a row of positioning grooves is provided on the right side of the triangular casting, wherein the row of positioning grooves is provided at equal intervals;
[0008] The triangular casting is provided with a row of heat dissipation holes at equal intervals, and the triangular casting is provided with two symmetrically distributed fixing holes;
[0009] The inner ends of the triangular casting are respectively grooved and positioned to install a first reinforcing rib and a second reinforcing rib, and the first reinforcing rib and the second reinforcing rib have the same structure and the same length;
[0010] The triangular casting is provided with a row of needle grooves matched with knitting needles, and a protective coating is attached to the groove walls of the needle grooves.
[0011] Preferably, sleeves are installed at the front and rear ends of the first reinforcing ribs and the second reinforcing ribs by means of screw nesting and positioning, wherein the diameters of the four sleeves are the same.
[0012] Preferably, the first reinforcement ribs and the second reinforcement ribs are both made of steel bar material.
[0013] Preferably, the inner ends of the four sleeves are respectively fixed with a first cross bar and a second cross bar by screws, wherein the two first cross bars and the two second cross bars are cross-arranged.
[0014] Preferably, the protective coating consists of a high-temperature resistant layer and a wear-resistant layer, and the wear-resistant layer is located on the surface of the high-temperature resistant layer.
[0015] Preferably, the high temperature resistant layer is a silicon carbide coating, and the high temperature resistant layer is a tantalum carbide coating.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] (1) A first reinforcing rib and a second reinforcing rib are provided. The first reinforcing rib and the second reinforcing rib are respectively installed by slotting and positioning the first and second reinforcing ribs at the two ends of the interior of the triangular casting. The first reinforcing rib and the second reinforcing rib can enhance the high strength performance of the triangular casting as a whole, thereby avoiding deformation and bending of the triangular casting during the knitting process of the triangular seat in the later stage, thereby improving the service life of the triangular casting;
[0018] (2) Furthermore, sleeves are installed at the front and rear ends of the first reinforcing rib and the second reinforcing rib by screw positioning, and then two first cross bars and two second cross bars are cross-installed on the inner sides of the four sleeves by screws. The connection stability between the first reinforcing rib and the second reinforcing rib can be enhanced by the two crossed first cross bars and the two second cross bars, thereby avoiding the phenomenon of misalignment and offset between the first reinforcing rib and the second reinforcing rib during use, thereby improving the stability of the triangular casting;
[0019] (3) A protective coating is provided. When the butt of the knitting needle moves at high speed in the needle groove, it will come into contact with the protective coating. The protective coating can reduce the wear of the needle butt, thereby ensuring the movement accuracy of the knitting needle;
[0020] (4) Furthermore, the protective coating is composed of a high-temperature resistant layer and a wear-resistant layer, which can increase the wear resistance and high-temperature resistance of the needle groove itself through the wear-resistant layer and the high-temperature resistant layer, thereby preventing the triangular casting at the wall of the needle groove from being greatly worn due to long-term friction with the knitting needles, thereby improving the service life of the triangular casting; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] This utility provides the following technical solutions:
[0031] Embodiment 1, in order to solve the problem that the existing triangular casting 1 does not have a stabilizing mechanism to support the high stability of the triangular casting 1, which may cause the triangular casting 1 to be easily bent and deformed after long-term use, the following embodiment is disclosed:
[0032] The triangular casting 1 and the positioning block 2 are positioned and installed on the left rear side of the triangular casting 1. A row of positioning grooves 3 are provided on the right side of the triangular casting 1, wherein the row of positioning grooves 3 are provided at equal intervals.
[0033] A row of heat dissipation holes 4 are formed on the triangular casting 1 at equal intervals, and two symmetrically distributed fixing holes 5 are formed on the triangular casting 1;
[0034] The triangular casting 1 can be fixed to the circular knitting machine by bolts through the fixing hole 5. At the same time, a positioning groove 3 and a positioning block 2 are provided. By arranging components that match the positioning groove 3 and the positioning block 2 on the circular knitting machine, a locking limit can be formed, thereby improving the firmness of the triangular casting 1 after installation, avoiding the deviation of the triangular casting 1 due to impact when the knitting needle moves at high speed, and facilitating the movement accuracy of the knitting needle.
[0035] When the knitting needle moves at high speed in the needle groove 14, it will rub against the triangular casting 1 at the wall of the needle groove 14, which will generate a lot of heat. The heat can be dissipated through the heat dissipation holes 4 to avoid aggravated wear of the knitting needle due to high temperature.
[0036] The first and second reinforcing ribs 7 and 8 are respectively slotted and positioned at both ends of the interior of the triangular casting 1 . The first and second reinforcing ribs 7 and 8 have the same structure and the same length.
[0037] The front and rear ends of the first reinforcing rib 7 and the second reinforcing rib 8 are both positioned and installed with sleeves 11 by screw nesting, wherein the four sleeves 11 have the same diameter, and the first reinforcing rib 7 and the second reinforcing rib 8 are both made of steel bar material.
[0038] The inner ends of the four sleeves 11 are respectively fixed with the first cross bars 9 and the second cross bars 10 by screws, wherein the two first cross bars 9 and the two second cross bars 10 are cross-arranged.
[0039] like Figures 1-6 As shown, when the triangular casting 1 is produced in conjunction with a circular knitting machine, the first reinforcing ribs 7 and the second reinforcing ribs 8 provided at both ends of the triangular casting 1 increase the high stability of the triangular casting 1 itself, thereby preventing the triangular casting 1 from deforming when used in conjunction with the triangular seat and the circular knitting machine in the later stage, thereby improving the stability of the triangular casting 1 in use;
[0040] At the same time, sleeves 11 are installed at the front and rear ends of the first reinforcing rib 7 and the second reinforcing rib 8 by means of screw positioning and nesting. At the same time, a first cross bar 9 and a second cross bar 10 are installed at the inner ends of each of the two sleeves 11 by means of screw positioning. The two first cross bars 9 and the two second cross bars 10 can be used to increase the seismic buffering performance between the first reinforcing rib 7 and the second reinforcing rib 8, thereby avoiding the bending deformation of the first reinforcing rib 7 and the second reinforcing rib 8 in the later stage, thereby improving the service life of the triangular casting 1 and making it more convenient for the stable processing and use of the circular knitting machine in the later stage.
[0041] The second embodiment is different from the first embodiment in that the wear resistance of the triangular casting 1 at the needle groove 14 can be improved by the protective coating 6, thereby avoiding serious wear of the triangular casting 1 at the needle groove 14 in the later stage, which is beneficial to the movement accuracy of the knitting needles.
[0042] A row of needle grooves 14 cooperating with knitting needles is provided on the triangular casting 1, and a protective coating 6 is attached to the groove wall of the needle groove 14.
[0043] The protective coating 6 consists of a high temperature resistant layer 12 and a wear resistant layer 13. The wear resistant layer 13 is located on the surface of the high temperature resistant layer 12. The high temperature resistant layer 12 is a silicon carbide coating. The high temperature resistant layer 12 is a tantalum carbide coating.
[0044] like Figure 1-Figure 7 As shown, when the triangular casting 1 is in use, the wear resistance of the triangular casting 1 at the wall of the needle groove 14 can be improved by the protective coating 6. When the knitting needle moves at high speed in the needle groove 14, the needle butt of the knitting needle will contact the protective coating 6, and the protective coating 6 is composed of a high-temperature resistant layer 12 and a wear-resistant layer 13. The high-temperature resistant layer 12 and the wear-resistant layer 13 are made of silicon carbide and tantalum carbide respectively. Silicon carbide has excellent material properties, such as high hardness, which can improve the wear resistance of the protective coating 6. The tantalum carbide coating has high hardness and high temperature resistance, which can improve the high temperature resistance of the protective coating 6. Silicon carbide and tantalum carbide cooperate with each other, so that the protective coating 6 has excellent wear resistance and high temperature resistance. In this way, the protective coating 6 can improve the service life of the triangular casting 1 and the movement accuracy of the knitting needle under long-term friction with the knitting needle.
