Description

Technical Field

[0001] This invention relates to a hot forging and stamping production line for a cylindrical knitting machine cylinder holder, belonging to the field of textile cylinders. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines or circular weft knitting machines, are characterized by their numerous loop-forming systems (referred to in industry as "number of yarn feed paths" or "number of loop formation paths"), high speed, high output, rapid pattern changes, good fabric quality, fewer processing steps, and strong product adaptability. Furthermore, the needle output for both horizontal and vertical knitting requires adaptation to the needle cylinder and upper and lower heart-shaped frame rails to form insert outputs, facilitating the operation of Schenker loop pressing and forming jacquard single and double-sided knitting. Therefore, their development has been rapid and diversified. Currently, the commonly used technology has the following shortcomings that need optimization:

[0003] Conventional steel materials are used for press-forging of syringe barrels and heart rings, followed by simple polishing and finishing. They are then directly placed into a lathe for milling. This results in uneven density of the steel inside the subsequently formed syringe barrel frame and heart components due to varying degrees of milling. Consequently, during the subsequent assembly on a large circular knitting machine, rigid impact cracking and oxidation breakage of the entire frame are prone to occur, leading to brittle deformation. This results in insufficient durability and shortened service life after assembly on the large circular knitting machine because the quality of the initial processing cannot be guaranteed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a hot forging and stamping production line for cylinder holders of circular knitting machines. This addresses the problem that conventional methods, such as pressing and forging of steel cylinders and inner rings, followed by simple polishing and finishing, often result in the cylinder holders and inner rings being directly placed into a lathe for milling. This leads to uneven density of the steel within the cylinder holders and inner rings due to varying degrees of milling, causing rigid impact cracking and oxidation breakage of the entire holder during subsequent assembly into a large circular knitting machine. Consequently, the durability of the assembled large circular knitting machine is insufficient, and the service life is shortened because the initial processing quality cannot be guaranteed.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a hot forging and stamping production line for a cylindrical knitting machine cylinder holder, the structure of which includes: a punching and forging press, a geothermal furnace cylinder trough, and a cylinder milling machine. The cylinder core assembly is installed on the top of the inside of the geothermal furnace cylinder trough and the axes are collinear. The milled cylinder ring is installed on the worktable of the cylinder milling machine. The cylinder core assembly is installed inside the punching and forging press. The geothermal furnace cylinder trough is provided with a cement block, a steel frame slot, thick electric heating pads, and the geothermal furnace trough. The steel frame slot is nested on the top of the geothermal furnace trough and the axes are collinear. The steel frame slot and the geothermal furnace trough are both inserted into the inside of the cement block. There are two or more thick electric heating pads, all of which are tightly attached to the inner ring surface of the geothermal furnace trough. The cylinder core assembly is installed inside the steel frame slot and the axes are collinear.

[0006] To optimize the above technical solution, the following further measures are taken:

[0007] As a further improvement of the present invention, the punching and forging press is composed of a machine tool top housing, a hydraulic column frame, a die plate pressure seat, a worktable, and a bed base. The hydraulic column frame is inserted into the top of the die plate pressure seat, the die plate pressure seat and the worktable are fitted with a clearance fit, the worktable is nested on the top of the bed base, the hydraulic column frame and the die plate pressure seat are both installed inside the machine tool top housing, and the machine tool top housing is welded to the top of the bed base and is perpendicular to each other.

[0008] As a further improvement of the present invention, the mold plate pressure seat is composed of an inner textured ring track groove, a pressure knife insert ring frame, and a mold pressure plate seat. The inner textured ring track groove and the pressure knife insert ring frame are nested together and have the same axis. Both the inner textured ring track groove and the pressure knife insert ring frame are installed inside the mold pressure plate seat.

[0009] As a further improvement of the present invention, the syringe heart kit is composed of a Schenker ring rail, a syringe inner shell, a thick cap ring frame, and a heart ring frame block. The Schenker ring rail is nested on the top of the syringe inner shell and the axes are collinear. The thick cap ring frame is nested on the top of the heart ring frame block. The syringe inner shell is inserted into the heart ring frame block and the axes are collinear.

[0010] As a further improvement of the present invention, the steel frame opening groove is composed of a frame ring opening, a double-layer ring groove, and an inner liner frame groove. The frame ring opening is nested on the top of the double-layer ring groove and the axes are collinear. The inner liner frame groove is installed inside the double-layer ring groove and the axes are collinear.

[0011] As a further improvement of the present invention, the thick heating patch is composed of a cable, an aluminum alloy plate, and a heating coil. There are two cables, both of which vertically penetrate the interior of the aluminum alloy plate. The aluminum alloy plate and the heating coil are nested together and are on the same vertical plane.

[0012] As a further improvement of the present invention, the needle milling machine is composed of a motor, a track frame plate, a milling cutter base, a material support plate, and a base block.

The thread inlet groove is provided in two or more and is nested together around the inner ring of the horizontal knitting needle plate.

[0015] Beneficial effects

[0016] This invention relates to a hot forging and stamping production line for a cylindrical knitting machine's needle cylinder holder. Workers place blocks of steel material into a forging press to assemble and forge four nested components: a Schenker ring rail, a needle cylinder inner shell, a thick-cap ring frame, and a heart-shaped ring frame block. The steel frame slot within the concrete floor of the geothermal furnace trough is then fitted with a thick electric heating pad to assist heating. The wide-mouthed frame receives the material, which then passes through the inner shell slot within a double-layered ring groove to protect the needle cylinder assembly. Embedded wires connect to the cable, which connects to the aluminum alloy thick plate and the heating coil, forming a high-temperature hot forging process reaching thousands of degrees Celsius. The built-in design enhances the forming effect of precision steel, allowing the motor of the needle cylinder milling machine to start and align the milling cutter base on the track frame plate with the material support plate and the top of the base block. This allows the milling machine to adjust the needle grooves of the needle cylinder, and the lifting slide, through the truss tube, inserts the milling cutter body of the truss vertical cutter to align with the inlet hole groove of the needle cylinder ring and the outer periphery of the horizontal knitting needle plate and the outer periphery of the vertical knitting needle plate and the insert needle groove. This creates a circular milling operation effect from the inside out, allowing the hot forging and stamping unit of the cylinder plate frame of the cylindrical knitting machine to achieve a tight fit and the steel auxiliary core components and the precision steel of the needle cylinder components to improve the forging and forming durability and deformation resistance.

[0017] The advantages that can be achieved after operating this invention are as follows:

[0018] By combining the syringe core assembly with the geothermal furnace cylinder groove, the various parts of the syringe core assembly are formed by punching and forging steel using a punching and forging press. Then, the steel frame of the frame, which is built into the geothermal furnace cylinder groove, including the Schenker ring rail, syringe inner shell, thick cap ring frame, and core ring frame block, undergoes a shrinkage operation to improve the density of the steel through hot forging with thick electric heating plates and the geothermal furnace groove. This improves the rigidity and strength of the subsequent syringe milling machine and enhances the rigidity, durability, and safety of subsequent assembly, preventing collision deformation. It also improves the overall cylindrical knitting machine's milling syringe ring frame hot forging process qualification rate and ensures the service life of subsequent knitting equipment assembly and production.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1:

[0031] Please see Figures 1-8 This invention provides a hot forging and stamping production line for a cylindrical knitting machine cylinder holder. Its structure includes: a blanking and forging press 1, a geothermal furnace cylinder trough 3, and a cylinder milling machine 4. The cylinder core assembly 2 is installed on the top of the geothermal furnace cylinder trough 3 and is coaxial. The milled cylinder ring 5 is installed on the worktable of the cylinder milling machine 4. The cylinder core assembly 2 is installed inside the blanking and forging press 1. The geothermal furnace cylinder trough 3 is provided with a cement floor 31. The system comprises a steel frame slot 32, thick electric heating pads 33, and a geothermal furnace trough 34. The steel frame slot 32 is nested on the top of the geothermal furnace trough 34 and the axes are collinear. Both the steel frame slot 32 and the geothermal furnace trough 34 are inserted into the interior of the cement block 31. There are two or more thick electric heating pads 33, which are tightly attached to each other around the inner circumference of the geothermal furnace trough 34. The syringe core kit 2 is installed inside the steel frame slot 32 and the axes are collinear.

[0032] Please see Figure 3The syringe heart kit 2 consists of a Schenck ring rail 21, a syringe inner shell 22, a thick cap ring frame 23, and a heart ring frame block 24. The Schenck ring rail 21 is nested on the top of the syringe inner shell 22 and the axes are collinear. The thick cap ring frame 23 is nested on the top of the heart ring frame block 24. The syringe inner shell 22 is inserted into the heart ring frame block 24 and the axes are collinear. The syringe inner shell 22 and the heart ring frame block 24 form an inner and outer insert combination to form the core component of the large circular machine.

[0033] Please see Figure 5 The steel frame slot 32 is composed of a frame opening 321, a double-layer annular groove 322, and an inner liner slot 323. The frame opening 321 is nested on the top of the double-layer annular groove 322 and the axes are collinear. The inner liner slot 323 is installed inside the double-layer annular groove 322 and the axes are collinear. The double-layer annular groove 322 and the inner liner slot 323 form a top auxiliary insert that fits in close contact with the built-in synchronous combination hot forging to improve the composite operation effect of the steel.

[0034] Please see Figure 6 The thick electric heating patch 33 is composed of a cable 331, an aluminum alloy thick plate 332, and an electric heating coil 333. There are two cables 331, both of which vertically penetrate the interior of the aluminum alloy thick plate 332. The aluminum alloy thick plate 332 and the electric heating coil 333 are nested together and are on the same vertical plane. The aluminum alloy thick plate 332 and the electric heating coil 333 form an electric heat transfer and aluminum heat diffusion to continuously raise the temperature of the geothermal furnace body for calcination.

[0035] Please see Figure 7 The syringe milling machine 4 consists of a motor 41, a track frame plate 42, a milling cutter base 43, a material support plate 44, and a base block 45. The motor 41 is installed on the front side of the track frame plate 42. The track frame plate 42 and the milling cutter base 43 are fitted with a clearance fit. The material support plate 44 is nested on the top of the base block 45. The track frame plate 42 is welded to the top of the rear side of the base block 45 and is perpendicular to each other. The milling cutter base 43 and the material support plate 44 form a stable lifting milling coordinate operation effect with a right angle vertical plane.

[0036] Please see Figure 1 The milling cutter base 43 is composed of a lifting slide 431, a milling cutter body 432, and a truss tube 433. The milling cutter body 432 is inserted into the left side of the truss tube 433 and is perpendicular to each other. The truss tube 433 horizontally penetrates the bottom of the lifting slide 431. The milling cutter body 432 supports the lifting slide 431 from the side, forming a stable and slow lifting mechanism for high-precision milling of needle grooves.

[0037] Please see Figure 8The milled needle cylinder ring 5 is composed of a thread inlet groove 51, a horizontal knitting needle plate 52, a vertical knitting needle plate 53, and a insert needle groove 54. The insert needle groove 54 has two or more pieces, all of which are inserted together around the axis of the vertical knitting needle plate 53. The vertical knitting needle plate 53 and the horizontal knitting needle plate 52 are nested together as one unit and their axes are collinear. The thread inlet groove 51 has two or more pieces, all of which are nested together around the inner ring of the horizontal knitting needle plate 52. The horizontal knitting needle plate 52 and the vertical knitting needle plate 53 form a composite needle cylinder ring assembly, which integrates the single and double sides of the frame and protects the operation of the built-in large circular knitting machine.

[0038] Workflow: Workers place blocks of steel material into a punching and forging press 1 to form four nested components for the syringe heart kit 2: Schenker ring rail 21, syringe inner shell 22, thick cap ring frame 23, and heart ring frame block 24. This allows the steel frame slot 32 within the concrete block 31 of the geothermal furnace trough 3 to assemble with the geothermal furnace trough 34, and thick electric heating pads 33 to be attached to the annular structure for auxiliary heating. The wide opening 321 of the frame ring receives the material, which then passes through the inner shell frame slot 323 within the double-layer annular groove 322 to protect the syringe kit. The embedded wires connect the cable 331 to the aluminum alloy thick plate 332 and the electric heating ring 333, forming a high-temperature hot forging process at over 1000 degrees Celsius, enhancing the precision of the steel. The operation effect of the milling machine 4 allows the motor 41 of the cylinder milling machine 4 to start and suspend the milling cutter base 43 on the track frame plate 42. The milling cutter base 43 is aligned with the material support plate 44 and the top of the base block 45 and is lifted and lowered to adapt to the milling operation of the cylinder. The lifting slide 431 passes through the truss tube 433 and inserts the milling cutter body 432 of the truss vertical cutter. It is aligned with the inlet hole groove 51 of the milling cylinder ring 5 and the outer periphery of the horizontal knitting needle plate 52 and the outer periphery of the vertical knitting needle plate 53 and the insert needle groove 54, forming a circular milling operation effect of needle groove row stitching from the inside to the outside. This allows the hot forging and stamping unit of the cylinder plate frame of the cylindrical knitting machine to be closely matched and the steel auxiliary core component and the precision steel of the cylinder component to improve the forging and strengthening, forming durability and deformation resistance operation effect.

[0039] Example 2:

[0040] Please see Figures 1-8 This invention provides a hot forging and stamping production line for a cylindrical knitting machine cylinder holder, which is the same as in Embodiment 1 in all other respects, except that:

[0041] Please see Figure 1The blanking and forging press 1 consists of a machine tool top housing 11, a hydraulic column frame 12, a die plate pressure seat 13, a worktable 14, and a bed base 15. The hydraulic column frame 12 is inserted into the top of the die plate pressure seat 13. The die plate pressure seat 13 and the worktable 14 are fitted with a clearance fit. The worktable 14 is nested on the top of the bed base 15. The hydraulic column frame 12 and the die plate pressure seat 13 are both installed inside the machine tool top housing 11. The machine tool top housing 11 is welded to the top of the bed base 15 and is perpendicular to each other. The die plate pressure seat 13 and the worktable 14 form a precise, fast, tight, and compliant blanking and forging operation.

[0042] Please see Figure 2 The mold plate pressure seat 13 is composed of an inner groove 131, a pressure knife ring holder 132, and a mold pressure plate seat 133. The inner groove 131 and the pressure knife ring holder 132 are nested together and have the same axis. The inner groove 131 and the pressure knife ring holder 132 are both installed inside the mold pressure plate seat 133. The inner groove 131 and the pressure knife ring holder 132 form the operation effect of steel material receiving and ring cutting of homogeneous seamless steel for synchronous punching and forging.

[0043] The process involves workers placing blocks of steel on the worktable 14 and bed base 15 of the punching and forging press 1, which are then fitted with the machine tool top housing 11. The hydraulic column frame 12 is then installed, and the mold plate pressure seat 13 is aligned. The inner groove 131 and the pressure knife ring frame 132 are then settled within the mold pressure plate seat 133 to form a die plate punching and forging process for annular syringe components. The inner groove 131 and the pressure knife ring frame 132 are flexibly adjustable to adapt to the pressing size and form efficient kits.

[0044] This invention, through the combination of the aforementioned components, achieves the following: using the syringe core assembly 2 in conjunction with the geothermal furnace cylinder groove 3, after the steel material of the syringe core assembly 2 is punched and formed by the punching and forging press 1, the Schenker ring rail 21, syringe inner shell 22, thick cap ring frame 23, and core ring frame block 24 are all built into the steel frame groove 32 of the geothermal furnace cylinder groove 3. The thick electric heating plate 33 is then combined with the geothermal furnace groove 34 for hot forging to improve the density of the refined steel. This shrinkage operation enhances the rigidity and strength of the subsequent syringe milling machine 4 during groove forming, and improves the rigidity, safety, and durability of subsequent assembly, preventing collision deformation. This also improves the overall cylindrical knitting performance. The milled-grooved needle cylinder ring 5-disc holder hot forging process improves the pass rate and ensures the service life of subsequent knitting equipment assembly and production. This solves the problem that after conventional steel material is used for press-forging of the needle cylinder and heart ring, it is easy to directly put it into the lathe for milling after simple polishing and finishing. This results in uneven density of the internal steel of the formed needle cylinder disc holder and heart component due to different milling degrees. This causes rigid collision cracking and oxidation breakage of the entire disc holder in the subsequent assembly of the circular knitting machine, which is easy to cause brittle deformation. This corresponds to the problem of insufficient durability and shortened service life of the subsequent circular knitting machine assembly, which is due to the failure to guarantee the pass rate of the initial processing.
