Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glass fiber production, and particularly relates to a modular multi-section drawing machine head. BACKGROUND

[0002] In the glass fiber drawing production, the drawing machine usually has two types, namely a direct yarn drawing machine and a cake yarn drawing machine, and their rotating speeds are high or low, and the high-speed centrifugal force is large. The direct yarn drawing machine head has a small diameter, and the expansion and contraction of the expansion piece is mainly realized by the two end taper sleeves, and the intermediate taper sleeve has a small thrust due to the insufficient space and can only be used as an auxiliary expansion and contraction. The intermediate taper sleeve must be symmetrically arranged and occupies a large space. On the contrary, the cake yarn drawing machine head has a large diameter, and the aluminum rotating cylinder is large and long, the front half part is hollowed out, the middle of the rear half part is fixed in cooperation with the taper of the main shaft, the length of the head is extended to be the same as the expansion piece by the aluminum rotating cylinder, but the long aluminum rotating cylinder and the expansion piece have a large processing difficulty, especially the aluminum rotating cylinder, which is easy to be damaged and has a large workload due to the complex processes such as deep hole drilling, taper turning, T-shaped groove milling and stress removal. It is difficult to guarantee the quality, especially in the maintenance and maintenance of users, and it is difficult to assemble and disassemble the super-long and super-heavy aluminum rotating cylinder. At the same time, if the length of the expansion piece is large, the rigidity of the middle part will be inevitably affected, and the existing expansion and contraction mechanism is easy to cause soft waist due to the insufficient top holding force.

[0037] Direction convention: please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2The head is completed by splicing along the omitted arc. The front direction in the application refers to the end of the head away from the motor base, and the direction opposite to the front is the rear direction. Correspondingly, the front end of a component or assembly refers to the end farther away from the motor base, and the rear end of a component or assembly refers to the end closer to the motor base.

[0038] Please refer to Figures 1-6 The modular head of the multi-drawing frame disclosed in the application comprises a head spindle 10, an upper wire ring 20, a pull rod seat 30, a broken bridge type expansion piece 40, and a plurality of segmented aluminum rotating cylinders 50. The number of segments of the segmented aluminum rotating cylinders 50 is flexibly configured according to the actual number of drawing, and in the embodiment, three segmented aluminum rotating cylinders 50 are included.

[0039] The three segmented aluminum rotating cylinders 50 are all fixedly assembled on the head spindle 10, the upper wire ring 20 is fixedly assembled on the front end of the head spindle 10, the pull rod seat 30 is fixedly assembled on the head spindle 10 and located behind the segmented aluminum rotating cylinders 50, and the broken bridge type expansion piece 40 is clampedly connected on the segmented aluminum rotating cylinders 50.

[0040] Between the upper wire ring 20 and the segmented aluminum rotating cylinders 50, between the segmented aluminum rotating cylinders 50 and the pull rod seat 30, and between every two adjacent segmented aluminum rotating cylinders 50, a telescopic mechanism assembly position 60 is arranged, and a expansion piece telescopic mechanism 70 is arranged in the telescopic mechanism assembly position 60.

[0041] Please refer to Figure 4 The segmented aluminum rotating cylinders 50 are provided with clamping positions, and the connecting parts of the broken bridge type expansion piece 40 have structures matching the clamping positions. When the broken bridge type expansion piece 40 is clampedly moved in the clamping positions, the clampedly moved connection can prevent the broken bridge type expansion piece 40 from falling off in the radial direction. The clampedly moved connection between the aluminum rotating cylinder and the expansion piece can be referred to Chinese patent: A head expansion piece middle taper sleeve supporting device (publication number CN213803526U).

[0042] The expansion piece has a length direction, and the expansion piece has a plurality of expansion piece broken bridge grooves 410 arranged in the length direction. The expansion piece broken bridge grooves 410 are evenly distributed in the length direction of the expansion piece and each expansion piece broken bridge groove 410 corresponds to one telescopic mechanism assembly position 60 and one expansion piece telescopic mechanism 70.

[0043] The expansion piece telescopic mechanism 70 comprises a piston ring 710, an inclined slope sliding block ring 720, a connecting rod sliding block 730, a connecting rod 740, a sliding block ring top spring 750, a sliding block tension spring 760, and an expansion piece tension spring 770.

[0044] The segmented aluminum drum 50 and the pull rod seat 30 are both provided with piston ring assembly grooves 5030. The piston ring 710 is fixedly assembled on the machine head spindle 10 through its assembly shaft hole. The piston ring assembly groove 5030 and the machine head spindle 10 define a piston ring drive cavity. The piston ring 710 is assembled in the piston ring drive cavity.

[0045] The ramp slider ring 720 is fixedly assembled on the head spindle 10 through its assembly shaft hole and contacts and cooperates with the piston ring 710.

[0046] The ramp slider ring 720 is provided with a plurality of ramp slider grooves 7210, and the connecting rod slider 730 is provided with a ramp matching portion 7310. The connecting rod slider 730 is assembled in the ramp slider groove 7210. The ramp matching portion 7310 and the ramp slider groove 7210 cooperate with each other through structurally matching slopes.

[0047] The connecting rod slider 730 is provided with a block upper rod head accommodating position 7330 , and the opening portion of the block upper rod head accommodating position 7330 is provided with a block upper rod head movable opening 7340 .

[0049] The connecting rod 740 includes a connecting rod portion 7410 and connecting rod heads 7420 disposed at both ends of the connecting rod portion 7410. The connecting rod heads 7420 are spherical connecting rod heads. The spherical connecting rod heads 7420 at both ends of the connecting rod 740 are movably connected to the rod head receiving position 7330 and the rod head matching receiving position 5031 on the block respectively.

[0050] The size of the connecting rod head 7420 is larger than the size of the rod head movable opening 7340 on the block and the rod head matching movable opening 5032. When the connecting rod slider 730 slides up or down along the slope slider groove 7210, the connecting rod head 7420 can move within the rod head accommodating position 7330 on the block and the rod head matching accommodating position 5031, but cannot be disengaged from the rod head accommodating position 7330 on the block and the rod head matching accommodating position 5031.

[0051] The segmented aluminum drum 50 and the upper wire ring 20 are both provided with a top spring seat hole 5020, and the ramp slider ring 720 is provided with a top spring insertion hole 7220. The ends of the slider ring top spring 750 are respectively disposed within the top spring seat hole 5020 and the top spring insertion hole 7220. When the piston ring 710 pushes the ramp slider ring 720 to compress the slider ring top spring 750, the slider ring top spring 750 can exert a force on the ramp slider ring 720 on the opposite side of the piston ring 710 through its elastic restoring force.

[0052] The connecting rod slider 730 is provided with a tension spring groove 7320, and the slider tension spring 760 is arranged in the tension spring groove 7320. The slider tension spring 760 surrounds the connecting rod slider 730 to provide a radial contraction force for the connecting rod slider 730.

[0053] The expansion springs 770 are disposed in the expansion spring slots 420 at both ends of the broken bridge expansion plate 40. The expansion springs 770 surround the plurality of expansion spring slots 420 to provide radial contraction force for the broken bridge expansion plate 40.

[0054] A spindle air path 110 is provided on the machine head spindle 10 , and the spindle air path 110 is connected to the piston ring drive chamber.

[0055] The number of connecting rod sliders 730, connecting rods 740, slider ring top springs 750 and the number of slope slider grooves 7210 can be flexibly configured according to the diameter of the segmented aluminum rotating drum 50. In this embodiment, the number of connecting rod sliders 730, connecting rods 740, slider ring top springs 750 is 12, and the number of slope slider grooves 7210 is also 12.

[0056] Principle and effect description:

[0057] When the compressed air is turned on, the piston ring 710 pushes the ramp slider ring 720 to move toward the front end, compressing the slider ring top spring 750; at the same time, after the connecting rod slider 730 loses the supporting effect of the ramp slider ring 720, it slides down along the ramp slider groove 7210 under the action of the slider tension spring 760, and the broken bridge expansion plate 40 contracts radially under the action of the expansion plate tension spring 770 after losing the supporting effect of the connecting rod slider 730.

[0058] When the compressed air is disconnected, the ramp slider ring 720 pushes the piston ring 710 into the piston ring drive chamber under the action of the slider ring top spring 750; at the same time, the connecting rod slider 730 slides up along the ramp slider groove 7210, and the broken bridge expansion piece 40 is expanded under the support of the connecting rod slider 730.

[0059] When the connecting rod slider 730 slides up or down along the slope slider groove 7210, the connecting rod 740 and the slope slider groove 7210 limit the up and down sliding range of the connecting rod slider 730 within a fixed range, so that when subjected to an upward sliding driving force or a downward sliding driving force, the connecting rod slider 730 can quickly and effectively respond, reduce invalid upward sliding or invalid downward sliding stroke, reduce system response time, and improve control accuracy and efficiency.

[0060] At the same time, when the expansion piece is lifted, the connecting rod 740 can also provide a normal limiting force (parallel to the main axis 10 of the machine head) on the connecting rod slider 730, preventing the connecting rod slider 730 from displacing on the expansion piece in a direction parallel to the main axis 10 when pushed by the ramp slider groove 7210, further ensuring the efficiency of the expansion piece extension. In addition, during the process of lifting the expansion piece, the connecting rod 740 can also provide radial support force to the connecting rod slider 730, partially absorbing the reaction force from the expansion piece, thereby balancing the force on the ramp slider ring 720 and improving the stability of the expansion piece extension and retraction action.

[0061] As the length of the sheet increases, the middle of the sheet will inevitably bend (soft waist). The cone sleeve placed in the middle of the sheet on existing wire drawing machines cannot solve the soft waist problem due to insufficient thrust, thus limiting the length of the die head. This application uses a newly developed sheet expansion and retraction mechanism to cooperate with the operation of the longer die head. This not only solves the soft waist problem that is common in longer sheet expansion, but also reduces system response time, improves control accuracy and efficiency, and increases the stability of the sheet expansion and retraction movement.

[0062] At the same time, because the broken bridge expansion plate 40 is provided with multiple expansion plate broken bridge grooves 410, the bending deformation points of longer expansion plates during operation are concentrated in the expansion plate broken bridge grooves 410. Corresponding to each expansion plate broken bridge groove 410, an expansion plate retracting mechanism 70 is provided. Therefore, even ultra-long, lightweight, and easily deformed expansion plates will not show a weakening phenomenon during operation. Therefore, the modular structure of the multi-branch wire drawing machine head disclosed in this application also allows for the lightweight development of expansion plates, thereby reducing the installation difficulty of the expansion plates and the centrifugal force during operation, reducing the power consumption of the wire drawing machine, and improving the expansion plate retraction control accuracy.

[0063] In a modified embodiment of the present application, the modular multi-bracing wire drawing machine head also includes a head front end cover 80, a head rear end cover 90, a dustproof maze 100, and a protective cover 200; the head front end cover 80 is fixedly assembled on the upper wire ring 20, and the head rear end cover 90, the dustproof maze 100, and the protective cover 200 are fixedly connected to the pull rod seat 30.

[0064] In a modified embodiment of the present application, the modular multi-bracing wire drawing machine head also includes a bearing seat 300, a coupling 400, a drive motor 500, and a motor seat 600; the head main shaft 10 is fixedly connected to the power output shaft of the drive motor 500 through the coupling 400, the coupling 400 is assembled in the motor seat 600, and the bearing seat 300 is fixedly assembled between the rear end cover 90 of the head and the motor seat 600.

[0065] The technical solutions and technical effects of the present application are described in detail above in combination with the accompanying drawings and specific embodiments, and it should be noted that other embodiments can be developed by those skilled in the art on the basis of the foregoing; any simple transformation and equivalent replacement without departing from the innovative concept of the present application are covered by the present application and belong to the protection scope of the present patent.
