Description

Technical Field

[0001] The present invention relates to the technical field of continuous extruders, in particular to an integrated spindle system for a continuous extruder. Background Art

[0002] A continuous extruder is a device that can continuously extrude metal materials through a die or working cavity to cause them to undergo plastic deformation or change shape. Its basic principle is to use pressure to make the material flow in a specific die or channel to obtain a product of the desired shape and size.

[0003] In the prior art, the main shaft system of a continuous extruder generally consists of a main shaft, bearings, and transmission components. The transmission components between the main shaft and the motor are generally connected by a coupling, and the coupling and the main shaft are connected by a spline. Due to the lack of precision in the spline connection, there is a gap between the key and the keyway. After long-term use of the continuous extruder, it will be subjected to repeated impact forces generated by starting and stopping the motor, so that the spline connection is subjected to repeated axial forces, resulting in the main shaft and the coupling becoming gradually loose in the axial direction. When the main shaft and the coupling become loose, collision or friction will occur between the components, causing abnormal noise and malfunctions during the operation of the continuous extruder.

DETAILED DESCRIPTION

[0038] The present invention will be described in further detail below with reference to the accompanying drawings.

[0039] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4As shown, an integrated spindle system for a continuous extruder includes a continuous extruder base 1, a drive motor 2 is provided on the continuous extruder base 1, a reducer 3 is connected to the right end of the drive motor 2, a transmission shaft 21 is provided at the right output end of the reducer 3, a shaft seat 4 located on the continuous extruder base 1 is provided outside the transmission shaft 21, a fixed frame 5 located on the continuous extruder base 1 is provided on one side of the shaft seat 4, a spindle assembly 31 is provided on the fixed frame 5, a spindle body 41 is provided inside the spindle assembly 31, a connecting end piece 61 connected to the drive shaft 21 is provided at the left end of the spindle body 41, the drive shaft 21 drives the spindle body 41 to rotate via the connecting end piece 61, and a compacting mechanism 51 is fixed to the fixed frame 5 and can support the spindle body 41 outside the spindle assembly 31;

[0040] The working principle of the present invention is as follows: the driving motor 2 is started and the speed is adjusted through the reducer 3, and the transmission is transmitted through the transmission shaft 21 to drive the main shaft body 41 to rotate in the main shaft assembly 31. The main shaft assembly 31 performs rotational support and continuous extrusion. The connecting end piece 61 is connected to the transmission shaft 21 through a spline type, and the connecting end piece 61 can avoid axial movement with the transmission shaft 21. The compacting mechanism 51 can assist in the extrusion of the metal material while avoiding the main shaft body 41 from cracking due to long-term unidirectional force.

[0041] Combined with attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 9 As shown, the spindle assembly 31 includes a bearing body 319 fixed to the left and right end side plates of the fixing frame 5 and sleeved on the outside of the spindle member 411. An extrusion wheel 311 sleeved on the outside of the spindle member 411 is provided between the two bearing bodies 319. The spindle member 411 is provided with a plurality of fixing keys 412. A plurality of fixing keys 413 are provided on both sides of the fixing key 412. A plurality of locking key grooves 320 are provided on the inner end surfaces of the bearing body 319 and the extrusion wheel 311. The fixing keys 413 and the fixing keys 412 are respectively engaged with the fixing keys 413 and the fixing keys 412, thereby fixing the spindle member 411, the bearing body 319, and the extrusion wheel 311.

[0042] Both sides of the two right-side bearing bodies 319 are provided with bearing outer end connecting rings 314 connected to the fixing frame 5, and both sides of the extrusion wheel 311 are provided with side end connecting rings 313. A sealing ring 315 is provided between the side end connecting rings 313 and the bearing outer end connecting rings 314. End rings 317 and shaft compartments 316 are respectively extended from the two opposite bearing outer end connecting rings 314. A sealing groove 414 is provided on the main shaft part 411. A sealing strip 318 is provided at the inner end of the end ring 317 and in the sealing groove 414.

[0043] Lubricating oil pipes are provided on both the end ring 317 and the shaft compartment 316 , which are connected to the hydraulic equipment located inside the continuous extruder base 1 . The lubricating oil is input through the lubricating oil pipe on the shaft compartment 316 and output through the lubricating oil pipe on the end ring 317 .

[0044] When the present invention is working: the main shaft member 411 drives the extrusion wheel 311 to rotate by clamping the fixed key 1 412 with the locking key slot 320, and drives the inner ring of the bearing body 319 to rotate by clamping the fixed key 2 413 with the locking key slot 320. The outer end connecting ring 314 of the bearing and the side end connecting ring 313 are sealed by the sealing ring 315. The outer ring of the bearing body 319 and the outer end connecting ring 314 of the bearing are both fixed to the fixing frame 5, that is, the connection between the outer ring of the bearing body 319 and the outer end connecting ring 314 of the bearing is in a stationary state, that is, only sealing means such as sealant and sealing gasket are required. The outer rings of the right bearing body 319 and the outer end connecting ring 314 of the bearing and the outer ring 314 of the bearing are also in a stationary state, and sealing means can be used in both cases.

[0045] That is, the end ring 317 and the interior of the shaft compartment 316 are connected. When lubricating oil is input into the shaft compartment 316 through the lubricating oil pipe on the shaft compartment 316, the lubricating oil contacts the right end of the transmission shaft 21. Under the action of the rotation of the transmission shaft 21 and the pressure of the lubricating oil, the lubricating oil gradually moves to the left. When the lubricating oil moves to the end ring 317, it is discharged from the lubricating oil pipe on the end ring 317. At this time, the gap between the main shaft assembly 31 and the main shaft body 41 becomes an integrated lubricating oil passage.

[0046] Embodiment: The first fixing key 412 and the second fixing key 413 on the main shaft body 41 are both provided with oil passages communicating with each other on the left and right, so as to facilitate the lubricating oil to pass through the bearing body 319 and the extrusion wheel 311 more quickly, thereby accelerating the flow rate of the lubricating oil.

[0047] Combined with attachment Figure 14 , Attachment Figure 15 , Attachment Figure 16 The cam 512 is connected to the cam 513 by the support rod 514, and the support rod 513 is connected to the support rod 515 by the support rod 516.

[0048] A second clamping block 518 is provided on the left and right end surfaces of the base 517 , and a first slide groove 520 is provided on the force applying rod 519 . The first slide groove 520 is slidably and rotatably connected to the second clamping block 518 .

[0049] The working principle of the compacting mechanism 51 is as follows: when the extrusion wheel 311 rotates, the electric telescopic rod 511 is started to extend, and the electric telescopic rod 511 drives the compacting wheel 513 to move down through the wheel seat 512 to compact the metal material into the feed trough 312, so as to facilitate the subsequent extrusion of the metal material. During the process, the wheel seat 512 drives the transmission folding rod 514 to move down, and the transmission folding rod 514 drives the other end of the force rod 519 to move down, so that one end of the force rod 519 moves up, and the one end of the force rod 519 drives the bottom support wheel 52 1 moves up until the bottom support wheel 521 contacts the material feeding trough 312 on the extrusion wheel 311. When the bottom support wheel 521 contacts the material feeding trough 312, it applies an upward force to the extrusion wheel 311 and the main shaft 411. At this time, the extrusion wheel 311 and the main shaft 411 are simultaneously subjected to downward and upward forces during the rotation process. The downward and upward forces greatly weaken the unidirectional force on the main shaft 411, thereby preventing the main shaft 411 from being broken due to the unidirectional pressure of the compacting wheel 513 for a long time.

[0050] When the bottom support wheel 521 moves up to its full position, the second clamping block 518 is located in the middle between the bottom support wheel 521 and the rotating block 515. At this time, the upward force of the bottom support wheel 521 is equal to the downward force of the compacting wheel 513.

[0051] During the startup of the electric telescopic rod 511, since the bottom support wheel 521 only moves up and down, the slide groove 1 520 slides on the block 2 518 during the rotation of the force rod 519, and the slide groove 2 522 slides on the block 1 516. Since the angle between the force rod 519 and the transmission folding rod 514 changes, the block 1 516 can drive the rotating block 515 to rotate to fit the slide groove 2 522.

[0052] Combined with attachment Figure 10 , Attachment Figure 11 , Attachment Figure 12 , Attachment Figure 13As shown, the transmission shaft 21 includes a shaft body 211 connected to the reducer 3, a shaft end 212 is provided at the right end of the shaft body 211, a spline groove 213 is provided in the shaft end 212, and a plurality of clamping grooves 214 are provided in the spline groove 213. The main shaft body 41 includes a main shaft member 411, and the connecting end member 61 includes an end member 611 fixed on the main shaft member 411, and a spline body 612 is provided on the end member 611 to be clamped with the spline groove 213, and a plurality of clamping grooves 214 are provided in the spline body 612. A through slot 613 is provided at a position corresponding to the engaging slot 214. A stopper 625 is provided in the through slot 613 and is engaged with the engaging slot 214. A shaft sleeve 619 is provided in the spline body 612 and is located inside the plurality of stoppers 625. A driving member 620 is provided at the left end of the shaft sleeve 619 to drive the stopper 625 to slide in the through slot 613. A second shaft hole 615 is provided on the end member 611. An adjusting block 630 is provided in the second shaft hole 615 and is engaged with the right end of the shaft sleeve 619 at its bottom end.

[0053] The driving member 620 is located in a cavity 616 provided at the left end of the spline body 612. A shaft sleeve 619 is provided in the first shaft hole 614 in the spline body 612. A fixed shaft 617 fixed to the main shaft member 411 is provided in the first shaft hole 614. The fixed shaft 617 is located in the shaft sleeve 619 and the driving member 620 and is rotatably connected to the shaft sleeve 619 and the driving member 620. A limiting shaft 618 is provided on the fixed shaft 617 and is located in the second shaft hole 615. The limiting shaft 618 is located in the adjustment block 630 and is rotatably connected to the adjustment block 630. A side sealing plate 629 is provided at the left end of the spline body 612.

[0054] The limiting member 625 includes a limiting card plate 626 that slides in the through slot 613 , and a spring 628 is provided on the side end surface of the limiting card plate 626 , which is connected between the bottom of the limiting card plate 626 and the inner wall of the cavity 616 ;

[0055] The driving member 620 includes a driving wheel 621 fixedly connected to the shaft sleeve 619, the fixed shaft 617 passes through the driving wheel 621, and a fixed block 622 corresponding to the number of the limiting member 625 is provided at the side end of the driving wheel 621. The two ends of the fixed block 622 are respectively provided with an ejection block 623 and a contraction block 624. The inner end surface of the limiting card 626 is provided with an arc-shaped end surface 627. The ejection block 623, the contraction block 624 and the arc-shaped end surface 627 are slidably connected. The curved end surface 627 slides on the arc surface of the ejection block 623 to drive the limiting clamping plate 626 to extend out of the through slot 613. When the curved end surface 627 passes through the ejection block 623 and moves onto the fixed block 622, the limiting clamping plate 626 contracts and is located between the ejection block 623 and the contraction block 624. When the curved end surface 627 passes through the contraction block 624 and moves between the contraction block 624 and the next ejection block 623, the limiting clamping plate 626 contracts and is retracted into the through slot 613.

[0056] One end of the ejection block 623 is connected to the fixed block 622 , and the other end is an arc-shaped end surface, and the tangent line of the bottom end tends to be parallel to the tangent line of the driving wheel 621 at the same position.

[0057] Before the drive motor 2 is started, the adjusting block 630 is rotated by a tool, and the adjusting block 630 drives the shaft sleeve 619 to rotate, and the shaft sleeve 619 drives the driving member 620 to rotate. During the rotation of the driving member 620, when the arc-shaped end surface 627 at the bottom end of the limiting clamping plate 626 contacts the ejection block 623, the ejection block 623 drives the limiting clamping plate 626 to move outward along the through groove 613. At this time, the spring 628 is compressed. When the limiting clamping plate 626 moves to the fixing block 622, the limiting clamping plate 626 is inserted into the clamping groove 214, which can prevent axial movement between the transmission shaft 21 and the main shaft body 41.

[0058] When the main shaft body 41 needs to be removed, continue to screw the adjustment block 630. At this time, the limit card 626 contacts the shrinkage block 624. When the limit card 626 moves to the driving wheel 621 through the shrinkage block 624, the main shaft body 41 can be removed from the transmission shaft 21.

[0059] Specific implementation method: The present invention provides an integrated spindle system for a continuous extruder. When the present invention is used to extrude metal materials:

[0060] The driving motor 2 is started and the speed is adjusted by the reducer 3, and the transmission is transmitted through the drive shaft 21 to drive the main shaft body 41 to rotate in the main shaft assembly 31. The connecting end piece 61 and the drive shaft 21 are spline-connected to avoid axial movement with the drive shaft 21. The compacting mechanism 51 can assist in the extrusion of the metal material while avoiding the main shaft body 41 from cracking due to long-term unidirectional force. The end ring 317 and the inside of the shaft compartment 316 are connected, so that the gap between the main shaft assembly 31 and the main shaft body 41 is an integrated lubrication oil circuit.
