Description

Technical Field

[0001] This application belongs to the technical field of glass fiber production equipment, and particularly relates to a socket type wire drawing machine head with a new modular structure. Background Art

[0002] In the production of glass fiber wire drawing, there are usually two types of wire drawing machines, namely direct yarn wire drawing machines and cake yarn wire drawing machines, and their speeds are high or low, and the high-speed centrifugal force is very large. The head diameter of the direct yarn wire drawing machine is small, and the expansion piece is mainly telescoped by the two end tapered sleeves. Due to the lack of space, the thrust of the middle tapered sleeve is small and can only be used as an auxiliary telescoping. The middle tapered sleeve must also be symmetrically arranged, occupying a large space. On the contrary, the head diameter of the cake yarn wire drawing machine is large, usually the aluminum rotating cylinder is large and long, the front half part is hollowed out, and the middle of the rear half part is fixed by taper fit with the main shaft. The extension of the head length is completed by the aluminum rotating cylinder to be the same length as the expansion piece. However, the processing of the long aluminum rotating cylinder and the expansion piece is difficult, especially for the aluminum rotating cylinder. Complex processes such as drilling deep holes, turning tapers, milling T-shaped grooves, and processing stress relief are prone to damage, and the workload is also very large, but it is difficult to ensure the quality, especially causing troubles to users in terms of maintenance. It is very difficult to install and disassemble the ultra-long and overweight aluminum rotating cylinder, and the requirements are very high.

[0057] To cooperate with the operation of the ultra-long machine head, the present application adopts a lightweight broken-bridge type expanding piece 40.

The aluminum rotating cylinder 50 on the shaft and the socket-type aluminum rotating cylinder 60 are provided with snap-fitting positions, and the connecting part of the broken-bridge type expanding piece 40 has a structure that matches the snap-fitting positions. When the broken-bridge type expanding piece 40 is movably snap-fitted in the snap-fitting positions, this movable snap-fitting connection can prevent the broken-bridge type expanding piece 40 from falling off radially. For the movable snap-fitting connection between the aluminum rotating cylinder and the expanding piece, please refer to the Chinese patent: A middle cone sleeve supporting device for the machine head expanding piece (the publication number is CN213803526U).

[0058] The broken-bridge type expanding piece 40 is provided with an expanding piece spring groove 410 and an expanding piece broken-bridge groove 420. The expanding piece spring groove 410 is arranged at the front and rear ends of the broken-bridge type expanding piece 40, and the expanding piece broken-bridge grooves 420 are evenly distributed in the length direction of the broken-bridge type expanding piece 40 and each expanding piece broken-bridge groove 420 corresponds to a telescopic mechanism installation position 70 and an expanding piece telescopic mechanism 80.

[0059] The expanding piece telescopic mechanism 80 includes a piston ring 810, a ramp slider ring 820, a connecting rod slider 830, a connecting rod 840, a slider ring top spring 850, and a slider spring 860. On both sides of the telescopic mechanism installation position 70, there are provided a top spring seat hole 710, a connecting rod hole 720, and a piston cavity 730.

[0060] The piston ring 810 is arranged in the piston cavity 730, and the ramp slider ring 820 is arranged in the telescopic mechanism installation position 70 and is in contact and cooperation with the piston ring 810.

[0061] The ramp slider ring 820 is provided with a plurality of ramp slider grooves 8210, and the connecting rod slider 830 is provided with a ramp mating part 8310. The connecting rod slider 830 is assembled in the ramp slider grooves 8210 and the ramp mating part 8310 and the bottom of the ramp slider grooves 8210 can form a sliding fit.

[0062] The connecting rod slider 830 is provided with a rod head accommodating position 8320. One end of the connecting rod 840 is movably connected to the rod head accommodating position 8320, and the other end of the connecting rod 840 is movably connected to the connecting rod hole 720. The opening part of the rod head accommodating position 8320 is provided with a rod head movable opening 8340, and the opening part of the connecting rod hole 720 is provided with a connecting rod movable opening 740. The connecting rod 840 includes a connecting rod part 8410 and connecting rod heads 8420 arranged at both ends of the connecting rod part 8410. The connecting rod heads 8420 at both ends of the connecting rod part 8410 are respectively movably assembled in the rod head accommodating position 8320 and the connecting rod hole 720.

[0063] The ramp slider ring 820 is provided with a top spring jack 8220. The two ends of the slider ring top spring 850 are respectively assembled in the top spring seat hole 710 and the top spring jack 8220. The slider ring top spring 850 acts on the side of the ramp slider ring 820 different from the piston ring 810.

[0064] The connecting rod slider 830 is provided with a slider tension spring groove 8330. The slider tension spring 860 is arranged in the slider tension spring groove 8330. The slider tension spring 860 surrounds the connecting rod slider 830 to provide a radial contraction force for the connecting rod slider 830.

[0065] The main air passage 110, the shaft cylinder air passage 510, and the socket cylinder air passage 610 communicate with the piston chamber 730.

[0066] The socket type wire drawing machine head with a new modular structure further includes a flapper tension spring 90; the flapper tension spring 90 is arranged in the flapper tension spring grooves 410 at both ends of the broken bridge type flapper 40. The flapper tension spring 90 surrounds the flapper tension spring grooves 410 of the broken bridge type flapper 40 to provide a radial contraction force for the broken bridge type flapper 40.

[0067] The socket type wire drawing machine head with a new modular structure further includes a front end cover 100 and a rear end cover 200 of the machine head; the front end cover 100 of the machine head is fixedly assembled on the wire feeding ring 20, and the rear end cover 200 of the machine head is fixedly assembled on the pull rod seat 30.

[0068] Among them: the numbers of the connecting rod slider 830, the connecting rod 840, and the slider ring top spring 850 can be flexibly configured according to actual needs. In this embodiment, the numbers of the connecting rod slider 830, the connecting rod 840, and the slider ring top spring 850 are all 12. Correspondingly, the number of the ramp slider grooves 8210 on the ramp slider ring 820 is also 12.

[0069] The realization mechanism of the flapper expansion and contraction mechanism:

[0070] When compressed air is turned on, the piston ring 810 pushes the ramp slider ring 820 to move forward, compressing the slider ring top spring 850; at the same time, after the connecting rod slider 830 loses the supporting effect of the ramp slider ring 820, it slides down along the ramp slider groove 8210 under the action of the slider tension spring 860. After the broken bridge type flapper 80 loses the supporting effect of the connecting rod slider 830, it radially contracts under the action of the flapper tension spring 90.

[0071] When the compressed air is turned off, the ramp slider ring 820 pushes the piston ring 810 into the piston ring chamber 730 under the action of the slider ring top spring 850; at the same time, the connecting rod slider 830 slides up along the ramp slider groove 8210, and the broken bridge type flapper 80 expands under the supporting effect of the connecting rod slider 830.

[0072] When the connecting rod slider 830 slides up or down along the ramp slider groove 8210, the connecting rod 840 and the ramp slider groove 8210 limit the up-and-down sliding range of the connecting rod slider 830 within a fixed range, so that when the upward or downward driving force is applied, the connecting rod slider 830 can quickly make an effective response, reduce the ineffective upward or downward sliding stroke, reduce the system response time, and improve the control accuracy and efficiency.

[0073] At the same time, when the expanding piece is jacked up, the connecting rod 840 can also provide a normal limiting force (parallel to the direction of the head spindle 10) to the connecting rod slider 830, preventing the connecting rod slider 830 from generating displacement on the expanding piece along the direction parallel to the head spindle 10 when being pushed by the ramp slider groove 8210, and further ensuring the efficiency of the expansion of the expanding piece. Moreover, during the process of jacking up the expanding piece, the connecting rod 840 can also provide a radial supporting force to the connecting rod slider 830, and a part of the reaction force from the expanding piece is borne by the connecting rod 840, so as to balance the force on the ramp slider ring 820 and improve the stability of the expanding piece expansion action.

[0074] In a multi-drawing ultra-long head wire drawing machine, as the length of the expanding piece increases, the middle part of the expanding piece is prone to bending (soft waist). The cone sleeve arranged in the middle of the expanding piece on the existing wire drawing machine cannot solve the soft waist problem due to insufficient thrust, thus restricting the development of the head length. The present application adopts a newly developed expanding piece telescopic mechanism to cooperate with the operation of the long head, not only solving the soft waist problem that is prone to occur in the longer expanding piece, but also reducing the system response time, improving the control accuracy and control efficiency, and increasing the stability of the expanding piece telescopic movement. At the same time, since a plurality of expanding piece break slots 420 are arranged on the broken bridge type expanding piece 40, the bending deformation points of the longer expanding piece during operation will be concentrated at the positions of the expanding piece break slots 420, and a corresponding expanding piece telescopic mechanism 80 is arranged at each position of the expanding piece break slot 420. Therefore, even for an ultra-long and lightweight and easily deformable expanding piece, no soft waist phenomenon will occur during operation. Thus, the disclosed novel modular structure socket type wire drawing machine head of the present application also allows the lightweight development of the expanding piece to reduce the processing and installation difficulty of the expanding piece and the centrifugal force during operation, reduce the power consumption of the wire drawing machine, and improve the control accuracy of the expanding piece telescopic movement.

[0075] In a variant embodiment of the present application, the socket type wire drawing machine head with a novel modular structure further includes a front bearing and bearing seat 3, an oil injection ring 4, a motor and motor seat 5, a rear bearing and bearing seat 6, a dust-proof deep cavity 7, and a rotary joint 8. The head spindle 10 is drivingly connected to the motor and motor seat 5. The front bearing and bearing seat 3 and the oil injection ring 4 are arranged at the front end of the motor and motor seat 5. The rear bearing and bearing seat 6 and the dust-proof deep cavity 7 are arranged at the rear end of the motor and motor seat 5. The rotary joint 8 is fixedly assembled at the rear end of the head spindle 10. An oil mist passage 31 is provided in the front bearing and bearing seat 3, and the oil mist passage 31 communicates with the oil injection ring 4. The socket type wire drawing machine head with a novel modular structure further includes a bobbin changing mechanism 9, and the bobbin changing mechanism 9 includes a bobbin changing turntable 91 and a bobbin changing bearing 92. The bobbin changing turntable 91 is used to drive the head to complete bobbin changing and flipping, and the bobbin changing bearing 92 is used to support the rotation of the bobbin changing turntable 91.

[0076] The technical solutions and technical effects of the present application have been elaborated in detail above in combination with the description drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not depart from the innovative concept of the present application are covered by the present application and belong to the protection scope of this patent.
