Description

Technical Field

[0001] The invention relates to the technical field of continuous extruders, and 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 their 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 the continuous extruder is generally composed 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. Since the fit between the spline connection may be insufficiently precise, 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 when the motor starts and stops, so that the spline connection is subjected to repeated axial forces, resulting in the main shaft and the coupling being gradually loosened in the axial direction. When the main shaft and the coupling are loose, collision or friction may occur between the components, resulting in abnormal noise and malfunctions during the operation of the continuous extruder.

The main shaft assembly 31 implements rotation support and continuous extrusion. The connecting end piece 61 is connected to the transmission shaft 21 by a spline, 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.

[0037] Combined with Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 As shown, the spindle assembly 31 includes a bearing body 319 fixed to the side plates at the left and right ends 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, a plurality of fixing keys 1 412 are provided on the spindle member 411, and a plurality of fixing keys 2 413 are provided on both sides of the fixing key 1 412, and a plurality of locking key grooves 320 are provided on the inner end surfaces of the bearing body 319 and the extrusion wheel 311, which are respectively engaged with the fixing keys 2 413 and the fixing keys 1 412, so that the spindle member 411 is fixedly connected with the bearing body 319 and the extrusion wheel 311; Both sides of the two right bearing bodies 319 are provided with bearing outer end connecting rings 314 connected to the fixing frame 5, both sides of the extrusion wheel 311 are provided with side end connecting rings 313, and sealing rings 315 are 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, and 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; Lubricating oil pipes are provided on the end ring 317 and the shaft chamber 316 , and the lubricating oil pipes 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 chamber 316 and output through the lubricating oil pipe on the end ring 317 .

[0038] When the present invention is working: the main shaft 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 on 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 static state, that is, only sealing means such as sealant and sealing gasket are needed. The outer ring of the right side bearing body 319 and the outer end connecting ring 314 of the bearing and the outer end connecting ring 314 of the bearing are also in a static state, and sealing means can be used. That is, the end ring 317 and the inside of the shaft compartment 316 are in a connected state. When the 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 pressurization of the lubricating oil, the lubricating oil gradually moves to the left, and 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 is an integrated lubricating oil path. Embodiment: The fixing key 1 412 and the fixing key 2 413 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 extruding wheel 311 more quickly, thereby accelerating the flow rate of the lubricating oil.

[0039] Combined with Fig.14 , Attachment Fig.15 , Attachment Fig.16 As shown, the compacting mechanism 51 includes an electric telescopic rod 511 fixed on the fixing frame 5, the bottom end of the electric telescopic rod 511 passes through the fixing frame 5 and is fixed with a wheel seat 512 at the bottom end, the extrusion wheel 311 is provided with a feeding trough 312, and the wheel seat 512 is provided with a compacting wheel 513 which cooperates with the feeding trough 312 to achieve the function of conveying materials, the front and rear end surfaces of the wheel seat 512 are both provided with two transmission folding rods 514, the bottom end of the transmission folding rod 514 is vertically downward, and two front and rear distributed bases 517 are fixedly provided at the bottom of the fixing frame 5, and the left and right end surfaces of the base 517 are both provided with a force applying rod 519 which can rotate and slide, one end of the force applying rod 519 is provided with a bottom supporting wheel 521 which is rollingly connected to the extrusion wheel 311, and the other end is provided with a second slide groove 522, a rotating block 515 is rotatably provided at the bottom end of the transmission folding rod 514, and two card blocks 1 516 which are located in the second slide groove 522 and are slidably connected to the second slide groove 522 are fixedly provided on the rotating block 515; The left and right end surfaces of the base 517 are both provided with a second clamping block 518 , and the force-applying rod 519 is provided with a first slide groove 520 , which is slidably and rotatably connected to the second clamping block 518 .

[0040] The working principle of the compaction 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 compaction wheel 513 to move downward 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 downward, and the transmission folding rod 514 drives the other end of the force rod 519 to move downward so that one end of the force rod 519 moves upward, and one end of the force rod 519 drives the bottom support wheel 52 1 moves upward until the bottom support wheel 521 contacts the feeding trough 312 on the extrusion wheel 311. When the bottom support wheel 521 contacts the feeding trough 312, it will give 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 will be subjected to downward and upward forces at the same time during the rotation process. The downward and upward forces will 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; When the bottom support wheel 521 moves up to the right 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. 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.

[0041] Combined with Fig.10 , Attachment Fig.11 , Attachment Fig.12 , Attachment Fig.13 As 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 clamped with the spline groove 213 is provided on the end member 611, and a plurality of clamping grooves 214 are provided in the spline body 612 A through slot 613 corresponding to the position of the clamping slot 214, a stopper 625 is slidably provided in the through slot 613 and is clamped with the clamping 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 in the shaft sleeve 619 and drives the stopper 625 to slide in the through slot 613, a second shaft hole 615 is provided on the end member 611, and an adjustment block 630 is provided in the second shaft hole 615 and is meshed with the right end of the shaft sleeve 619; The driving member 620 is located in a cavity 616 provided at the left end of the spline body 612, a sleeve 619 is provided in the shaft hole 1 614 in the spline body 612, a fixed shaft 617 fixed to the main shaft member 411 is provided in the shaft hole 1 614, the fixed shaft 617 is located in the sleeve 619 and the driving member 620 and is rotatably connected with the sleeve 619 and the driving member 620, a limiting shaft 618 located in the shaft hole 2 615 is provided on the fixed shaft 617, the limiting shaft 618 is located in the adjustment block 630 and is rotatably connected with the adjustment block 630, and a side sealing plate 629 is provided at the left end of the spline body 612; The limiting member 625 includes a limiting clamping plate 626 sliding in the through slot 613, and a spring 628 connected between the bottom of the limiting clamping plate 626 and the inner wall of the cavity 616 is provided on the side end surface of the limiting clamping plate 626; 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 fixing block 622 corresponding to the number of the limiting member 625 is provided at the side end of the driving wheel 621, and an ejection block 623 and a contraction block 624 are respectively provided at both ends of the fixing block 622, and an arc-shaped end surface 627 is provided at the inner end surface of the limiting clamping plate 626, and the ejection block 623, the contraction block 624 and the arc-shaped end surface 627 are slidably connected. The arc-shaped end surface 627 drives the limit clamping plate 626 to extend out of the through slot 613 by sliding on the arc surface on the ejection block 623. When the arc-shaped end surface 627 passes through the ejection block 623 and moves onto the fixed block 622, the limit clamping plate 626 shrinks and is located between the ejection block 623 and the shrinking block 624. When the arc-shaped end surface 627 passes through the shrinking block 624 and moves between the shrinking block 624 and the next ejection block 623, the limit clamping plate 626 shrinks into the through slot 613. One end of the ejector 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.

[0042] Before the driving motor 2 is started, the adjusting block 630 is rotated by a tool, 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, and the spring 628 is compressed at this time. 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 the transmission shaft 21 and the main shaft body 41 from axial movement. When the main shaft body 41 needs to be removed, continue to screw the adjustment block 630, at this time the limit clamping plate 626 contacts the shrinking block 624, when the limit clamping plate 626 moves to the driving wheel 621 through the shrinking block 624, the main shaft body 41 can be removed from the transmission shaft 21.

The connecting end piece 61 and the transmission shaft 21 are splined to avoid axial movement with the transmission shaft 21. The compaction 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.
