Description

TECHNICAL FIELD

[0001] The application relates to the technical field of turning processing, in particular to a turning device for metal roller processing. BACKGROUND

[0002] As a core component of a rolling mill, the machining precision of a metal roller directly affects the quality of rolled plates. In a traditional turning process, due to the high hardness and large cutting resistance of the roller material, a large amount of cutting heat is generated during the turning process, which causes the temperature of the workpiece to rise sharply. The heat will cause thermal deformation of the roller, resulting in a shift in the axial size of the roller;

[0003] On the one hand, the radial expansion of the roller due to temperature rise and the shrinkage after cooling after turning will cause the final size of the roller to deviate from the target size, affecting the length precision of the roller. On the other hand, thermal deformation will also cause shape errors of the roller, reducing its cylindricity. At the same time, during the turning process, the clamping and machining precision of the roller also face challenges, and it is difficult to accurately detect and compensate the run-out tolerance of the roller in real time, thereby effectively ensuring the machining quality of the roller.

[0048] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is merely meant to provide a better understanding of the subject matter described herein and can be changed in function and arrangement without departing from the scope of the present disclosure. Various processes or components can be omitted, substituted, or added according to desired implementations. Additionally, features described with respect to some examples can be combined in other examples.

[0049] Referring to Figure 1 , Figure 2 and Figure 3 , a turning device for metal roller processing is disclosed, which comprises a base 100, a top support unit 200, a clamping driving unit 300, a run-out detection unit 500, a turning unit 600, and a controller.

[0050] Referring to Figure 4The clamping driving unit 300 is arranged on one side of the base 100, and includes a laterally movable driving motor 340, and a clamping piece 350 connected to one end of the driving motor 340 and adapted to the roller 700;

[0051] Referring to Figure 4 The top support unit 200 is arranged on the base 100 and located on the opposite side of the clamping driving unit 300, and includes a sleeve 210 and a sliding cylinder 220 axially slidingly arranged in the sleeve 210, and a sleeve 230 coaxially and rotatably connected to one end of the sliding cylinder 220 facing the clamping piece 350, and an axial adjusting piece arranged on one side of the sleeve 210 for driving the sliding cylinder 220;

[0052] The turning unit 600 is arranged on the base 100 and used for turning the roller 700;

[0053] Referring to Figure 7 The bounce detection unit 500 is arranged above the sleeve 210, and includes a laterally movable sliding block 560 and a detection rod 580 arranged below the sliding block 560, and the detection rod 580 is used for detecting the axial bounce tolerance of the roller 700;

[0054] A controller is used for controlling the axial adjusting piece to drive the sliding cylinder 220 to axially slide and adjust according to the axial bounce tolerance detected by the detection rod 580, so as to compensate for the axial size drift of the roller 700 in the turning process.

[0055] Specifically, one end of the roller 700 with a rectangular end is inserted into the clamping piece 350, the roller 700 is clamped and fixed by the clamping piece 350, the driving motor 340 is laterally moved until the other end of the roller 700 is inserted into the sleeve 230, and the roller 700 is axially clamped and fixed by the sleeve 230 and the clamping piece 350, then the driving motor 340 is started to drive the roller 700 to rotate, and the turning unit 600 is used for turning the outer circumferential surface of the roller 700;

[0056] During the turning process, the sliding block 560 can be synchronously displaced along the turning path of the turning unit 600, the detection rod 580 is used for detecting the axial bounce of the turning part, and the controller controls the axial adjusting piece to drive the sliding cylinder 220 to axially slide and adjust according to the axial bounce tolerance detected by the detection rod 580, when the roller 700 is detected to be radially expanded due to temperature rise, the sleeve 230 is axially displaced to offset the contraction of the roller 700 after cooling, so as to compensate for the axial size drift of the roller 700 in the turning process.

[0057] It needs to be explained that the present application continuously and real-timely detects the axial run-out tolerance of the turning part of the roll 700 in the turning process through the detection rod 580 in the run-out detection unit 500, and the run-out directly or indirectly reflects the workpiece thermal deformation state caused by cutting heat, including the radial expansion trend and the subsequent axial shrinkage problem caused thereby;

[0058] The controller accurately calculates the compensation displacement required for pre-offsetting the axial shrinkage of the roll 700 after cooling according to the run-out tolerance data collected by the detection rod 580 in real time (reflecting the instantaneous size change and potential deformation trend caused by thermal expansion during turning), generates a compensation instruction, drives the axial adjusting part to act, and pushes the sliding cylinder 220 to accurately slide axially in the sleeve seat 210, and the movement of the sliding cylinder 220 is transmitted to the supporting end of the roll 700 through the sleeve 230 coaxially connected to the end of the sliding cylinder 220;

[0059] The axial adjusting part drives the sliding cylinder 220 to move axially, and pushes the sleeve 230 to exert a small controllable axial pre-stretching force on the roll 700, so that the roll 700 is in a slightly stretched state under the high-temperature state of turning, and when the turning is completed and the roll is cooled and shrunk, the final length falls back to the target size, effectively inhibiting the length dimension of the roll caused by the cooling and shrinking of the material, indirectly inhibiting the shape error caused by the radial thermal expansion, and improving the cylindricity.

[0060] In an embodiment, please refer to Figure 4 and Figure 5 The axial adjusting part includes an adjusting electric cylinder 250 fixed to one side of the sleeve seat 210, the adjusting electric cylinder 250 is connected with a push-pull clamping plate 260 at the output end, the sliding cylinder 220 is provided with a clamping groove 270 matched with the push-pull clamping plate 260, and the sliding cylinder 220 is also circumferentially provided with a plurality of limiting sliding strips 221 matched with the sleeve seat 210 for sliding;

[0061] Specifically, the sliding cylinder 220 is axially limited by the limiting sliding strips 221, so that the sliding cylinder 220 can only slide axially relative to the sleeve seat 210, and the sleeve 230 can rotate freely circumferentially relative to the sliding cylinder 220, so that the sleeve 230 can rotate synchronously with the roll 700 during turning, and at the same time, the axial adjusting part can drive the sleeve 230 to move axially to realize the slight stretching effect on the roll 700;

[0062] The push-pull clamping plate 260 is clamped in the clamping groove 270, and when it is necessary to adjust the sleeve 230 circumferentially, the push-pull clamping plate 260 is driven to move laterally by the adjusting electric cylinder 250, so as to pull the sliding cylinder 220 to move axially synchronously, so as to realize the slight axial stretching of the sleeve 230 on the roll 700.

[0063] It should be noted that the limiting slide bar 221 arranged on the slide cylinder 220 is in sliding fit with the inner wall of the sleeve base 210, so that the slide cylinder 220 can only slide linearly along the axial direction of the sleeve base 210, effectively eliminating the possibility of any shaking or yawing of the slide cylinder 220 in the radial or circumferential direction, ensuring that the compensation force applied to the roll 700 is a purely and directionally accurate axial force, and the compensation action does not introduce additional geometric errors;

[0064] The sleeve 230 is coaxially connected with the end of the slide cylinder 220, and when the electric cylinder 250 drives the slide cylinder 220 to slide axially by pushing and pulling the clamping plate 260 and the clamping groove 270, the sleeve 230 itself will not be forced to twist due to the movement of the slide cylinder 220, and the sleeve 230 can freely follow the synchronous rotation of the clamped roll 700, unaffected by the axial adjustment action, thereby realizing the decoupling of the rotational motion of the roll 700 and the compensation required axial translational motion. During the compensation process, the rotation of the roll 700 is smooth and unobstructed, and there is no harmful relative sliding friction between the sleeve 230 and the end face of the roll, thereby effectively avoiding the scratching of the workpiece surface and the abnormal wear of the sleeve 230.

[0065] Further, please refer to Figure 4 The clamping driving unit 300 further comprises a first sliding rail 310 fixed transversely on the base 100, a first sliding table 320 is slidingly installed on the first sliding rail 310, and the driving motor 340 is fixedly installed on the first sliding table 320. One end of the first sliding rail 310 is provided with a first electric cylinder 330 for driving the first sliding table 320;

[0066] Specifically, after the roll 700 is clamped and fixed at one end by the clamping piece 350, the first sliding table 320 is driven to slide transversely along the first sliding rail 310 by the first electric cylinder 330, until the other end of the roll 700 is inserted into the sleeve 230 and connected with the sleeve 230 by expansion, thereby realizing the fixation of both ends of the roll 700.

[0067] Further, please refer to Figure 4 and Figure 6 The clamping piece 350 comprises a rotating sleeve 351 coaxially fixedly connected with the output end of the driving motor 340, a push plate 352 is axially slidingly embedded in the rotating sleeve 351, and a rectangular limiting groove 353 adapted to the rectangular end of the roll 700 is formed at the center of the push plate 352; a plurality of radial clamping blocks 354 are arranged circumferentially on the push plate 352, and a wedge-shaped block 355 adapted to the inner wall of the rotating sleeve 351 is arranged at one end of the radial clamping block 354 away from the push plate 352;

[0068] Specifically, one end of the roller 700 with a rectangular head is inserted into the sleeve 351, so that the rectangular head is just inserted into the rectangular limiting groove 353, thereby limiting the roller 700 in the circumferential direction by the rectangular limiting groove 353, avoiding the circumferential deflection of the roller 700 and the sleeve 351 during turning; then the push plate 352 is pushed to slide along the sleeve 351 in the axial direction, thereby driving the wedge-shaped block 355 of each radial clamping block 354 to relatively displace with the sleeve 351, the wedge-shaped block 355 is radially extruded by the sleeve 351, forcing each group of radial clamping blocks 354 to radially contract, so that the radial clamping blocks 354 press the outer peripheral surface of the end portion of the roller 700, realizing the clamping and fixing of the roller 700.

[0069] It should be noted that the rectangular head of the end portion of the roller 700 is accurately inserted into the rectangular limiting groove 353 in the center of the push plate 352, forming a rigid torsion-resistant connection, preventing any circumferential relative rotation or deflection between the roller 700 and the sleeve 351 during turning, and ensuring effective torque transmission.

[0070] When the push plate 352 moves in the axial direction, the radial clamping block 354 and the wedge-shaped block 355 thereon move synchronously, the inclined surface of the wedge-shaped block 355 interacts with the tapered surface of the inner wall of the sleeve 351, the inner wall of the sleeve 351 generates a radially inward extrusion force on the wedge-shaped block 355, forcing all radial clamping blocks 354 to synchronously contract radially towards the center, thereby firmly pressing on the outer peripheral surface of the end portion of the roller 700, providing strong radial clamping force to prevent axial movement or radial jumping of the workpiece.

[0071] Correspondingly, please refer to Figure 6 The clamping and driving unit 300 further comprises an air chamber 360 fixed to the output end of the driving motor 340, a sealing ring 362 is arranged at the connection between the air chamber 360 and the sleeve 351, one side of the air chamber 360 is connected with an air pipe 361, and a gas cavity 356 is formed in the sleeve 351, a plurality of through holes 357 are formed in the side wall of the gas cavity 356 and communicate with the air chamber 360.

[0072] Specifically, when the roller 700 needs to be clamped, the air chamber 360 is inflated through the air pipe 361, the gas enters the gas cavity 356 through the through holes 357, so that the air pressure in the gas cavity 356 increases, thereby pushing the push plate 352 to move towards one end of the roller 700, and prompting each group of radial clamping blocks 354 to radially contract, so as to realize the clamping and fixing of the roller 700.

[0073] It is worth noting that by filling compressed air into the air chamber 360 through the air pipe 361, the gas enters the air cavity 356 inside the rotating sleeve 351 through the through hole 357, the increased air pressure in the air cavity 356 uniformly acts on the entire end face of the push plate 352, generates a strong axial thrust, and smoothly and quickly pushes the push plate 352 to move in the direction of the end of the roller 700. The axial movement of the push plate 352 automatically triggers the radial contraction and clamping action of the radial clamping block 354; when loosening, only the gas needs to be released, and the clamping force can be released. Moreover, the clamping effect on the roller 700 can be continuously maintained during the turning process, and the rotation of the roller 700 itself is not affected.

[0074] In yet another embodiment, referring to Figure 7 , the bounce detection unit 500 further includes a mounting seat 510 fixed above the sleeve 210, a second sliding rail 520 vertically mounted on the mounting seat 510, a second sliding table 530 slidingly mounted on the second sliding rail 520, and a second electric cylinder 540 mounted on the top of the mounting seat 510 and used to drive the second sliding table 530; a guide rod 550 is fixed horizontally on the second sliding table 530, a sliding block 560 is slidingly sleeved on the guide rod 550, and springs 570 are movably sleeved on both ends of the guide rod 550 and abut against the sliding block 560;

[0075] Specifically, in the initial state, the sliding block 560 is at the central position of the guide rod 550, and before the turning process, the second sliding table 530 is driven by the second electric cylinder 540 to descend to the set position, so that the detection rod 580 is in contact with the top position of the outer peripheral surface of the roller 700; when the turning unit 600 performs the turning process on the roller 700, the sliding block 560 can follow the turning path of the turning unit 600 to move synchronously and horizontally along the guide rod 550, so as to detect the run-out tolerance of the turning position in real time through the detection rod 580.

[0076] Further, referring to Figure 8 , the detection rod 580 includes a rod body 581 fixed below the sliding block 560, a cavity 582 is formed in the rod body 581, a sliding carriage 583 is vertically and slidingly embedded at the opening of the lower end of the cavity 582, and an alloy roller 584 is movably embedded at the lower end of the sliding carriage 583; a rotating shaft 585 is installed in the cavity 582, a swing rod 586 is rotationally connected to the rotating shaft 585, a through slot 587 is formed at the lower end of the swing rod 586, a locking pin 588 movably embedded in the through slot 587 is arranged on the sliding carriage 583, and a yaw meter 589 matched with the upper end of the swing rod 586 is arranged at the top of the cavity 582;

[0077] Specifically, under the action of gravity, the sliding frame 583 is freely slid downward from the cavity 582, so that the alloy roller 584 is always in contact with the outer circumferential surface of the roller 700. When the roller 700 locally jumps in size due to high temperature generated by turning, the alloy roller 584 can synchronously push the sliding frame 583 to vertically slide, so that the roller 700 drives the swing lever 586 to swing around the rotation shaft 585 under the cooperation of the pin 588 and the through slot 587, and then the swing angle of the upper end of the swing lever 586 is collected by the swing instrument 589, so as to map the jump tolerance of the roller 700.

[0078] It is worth noting that in the embodiment, the jump tolerance generated by the roller 700 triggers the vertical jump of the alloy roller 584 and the sliding frame 583, and then drives the swing lever 586 to swing, which magnifies the small jump of the alloy roller 584 into the large swing of the swing lever 586, and the angle is captured by the swing instrument 589, so as to effectively improve the detection accuracy of the jump; the alloy roller 584 can be a hard copper alloy, which is in rolling contact with the outer circumferential surface of the roller 700, and the friction is relatively small, so it will not cause wear or scratches on the outer circumferential surface of the roller 700.

[0079] In addition, the swing angle of the swing lever 586 and the jump value of the alloy roller 584 have a mutual mapping relationship, that is, a mapping table of the jump value of the alloy roller 584 and the swing angle of the swing lever 586 can be preset, and according to the preset mapping table, the jump value of the alloy roller 584 can be calculated according to the swing angle of the upper end of the swing lever 586 captured by the swing instrument 589, that is, the jump tolerance of the roller 700 is indirectly reflected.

[0080] It should be noted that the second sliding table 530 is vertically lifted along the second sliding rail 520 by the second electric cylinder 540, so that the detection mechanism can be quickly and accurately moved to a set height, so that the alloy roller 584 at the lower end of the detection rod 580 can be in contact with the outer circle top of the roller 700; during the turning process, the sliding block 560 can freely slide along the guide rod 550, and the movement is controlled by the turning unit 600, so that the alloy roller 584 can always follow the turning path of the turning unit 600 to move horizontally, so as to detect the jump at the current turning position in real time, and avoid the problem of detection point lag;

[0081] The sliding of the sliding block 560 on the guide rod 550 is flexibly constrained and centrally reset by the spring 570 movably sleeved at both ends of the guide rod 550, so that the sliding block 560 and the detection rod 580 carried thereby can adapt to the vibration or slight path deviation of the machine tool during following, and the spring 570 also serves as a buffer to prevent structural damage or measurement distortion caused by accidental collision or excessive jump;

[0082] The alloy roller 584 is in direct rolling contact with the surface of the rotating roller 700, and the radial runout of the roller 700 pushes the alloy roller 584, driving the sliding frame 583 to vertically slide in the cavity 582 of the rod body 581. The pin 588 on the sliding frame 583 is embedded in the through slot 587 at the lower end of the swing lever 586, converting the linear displacement of the sliding frame 583 into the rotary motion of the swing lever 586 around the rotation shaft 585. The slight vertical runout of the sliding frame 583 causes the swing lever 586 to produce a significantly amplified deflection angle (the amplification factor is determined by the ratio of the distance from the pin 588 to the rotation shaft 585 to the length of the swing lever 586), thereby amplifying the micron-level radial runout into an angular displacement that is easy to capture by the instrument, greatly improving the detection sensitivity and resolution.

[0083] The alloy roller 584 in contact with the roller 700 is made of hard copper alloy material (hardness lower than that of the roller), and is in rolling contact. The rolling friction coefficient is extremely small, and the contact pressure is controllable, completely avoiding the surface scratches or rapid wear of the roller 700 that may be caused by traditional probes, ensuring the long-term reliability of the detection and the surface quality of the workpiece.

[0084] The swing instrument 589 (such as a high-precision angle sensor) is arranged at the top of the cavity 582 and is used to accurately capture the deflection angle of the upper end of the swing lever 586. According to the mapping relationship (a mapping table or function can be established through experiments) between the deflection angle (θ) of the swing lever 586 and the runout value (Δh) of the alloy roller 584, which is pre-calibrated, the actual radial runout tolerance (Δh) of the roller 700 at the current detection point can be accurately converted from the measured θ.

[0085] In further embodiments, please refer to Figure 9 The turning unit 600 comprises a longitudinal sliding rail 610 fixed on the base 100, a longitudinal sliding table 620 slidingly installed on the longitudinal sliding rail 610, and a longitudinal electric cylinder 630 installed at one end of the longitudinal sliding rail 610 and used to drive the longitudinal sliding table 620. The longitudinal sliding table 620 is fixed with a transverse sliding rail 640, the transverse sliding table 650 is slidingly installed on the transverse sliding rail 640, and the transverse motor 660 is installed at one end of the transverse sliding rail 640 and used to drive the transverse sliding table 650. The transverse sliding table 650 is provided with a turning tool 670.

[0086] Specifically, the longitudinal electric cylinder 630 drives the longitudinal sliding table 620 to longitudinally slide along the longitudinal sliding rail 610, which can drive the turning tool 670 to approach the roller 700 radially, thereby adjusting the cutting amount. The transverse motor 660 drives the transverse sliding table 650 to transversely slide along the transverse sliding rail 640, which can drive the turning tool 670 to move along the roller 700 in the axial direction, thereby realizing the axial turning of the roller 700.

[0087] Further, please refer to Figure 7 andFigure 9 In order to realize the synchronous movement of the detection rod 580 and the turning tool 670, the cross-moving slide 650 is provided with a plug 680, and the sliding block 560 is provided with a plug hole 561 matched with the plug 680;

[0088] Specifically, the cross-moving slide 650 is driven by the cross-moving motor 660 to move along the cross-moving slide rail 640, so as to drive the turning tool 670 to move along the roller 700 in the axial direction, until the plug 680 is aligned with the plug hole 561, then the longitudinal-moving slide 620 is driven by the longitudinal-moving electric cylinder 630 to move along the longitudinal-moving slide rail 610 in the lateral direction, so as to drive the turning tool 670 to move radially towards the roller 700, and the plug 680 is just inserted into the plug hole 561, and then the turning tool 670 moves in the lateral direction (i.e. moves along the roller 700 in the axial direction), so as to drive the sliding block 560 to move along the guide rod 550 in the axial direction by the plug 680, so as to realize the synchronous movement of the detection rod 580 and the turning tool 670, and ensure the real-time detection accuracy and responsiveness.

[0089] It is worth noting that the sliding block 560 is rigidly connected with the cross-moving slide 650 by the physical plug-in cooperation of the plug 680 and the plug hole 561 during the turning process, when the cross-moving slide 650 is driven by the cross-moving motor 660 to move in the axial direction along the cross-moving slide rail 640 (i.e. in the turning feed direction), the sliding block 560 is driven to move in the axial direction along the guide rod 550 by the rigid connection of the plug 680 and the plug hole 561, so as to ensure that the axial position of the alloy roller 584 at the lower end of the detection rod 580 is always consistent with the cutting point of the turning tool 670, realize the zero distance and zero lag following of the detection point and the machining point, and obtain the real-time and true thermal deformation runout data.

[0090] In addition, the plug 680 is first aligned with the plug hole 561 by driving the cross-moving slide 650 to move in the axial direction by the cross-moving motor 660, and then the plug 680 is inserted into the plug hole 561 by driving the longitudinal-moving slide 620 to move in the radial direction by the longitudinal-moving electric cylinder 630, so as to naturally insert the plug 680 into the plug hole 561 while the turning tool 670 moves towards the roller 700, and the linkage action is highly integrated with the turning preparation action (radial feed), without increasing additional operation steps, and the position locking of the detection rod 580 and the turning tool 670 is automatically completed before starting the axial turning.

[0091] In another embodiment, please refer to Figure 10 , Figure 11 and Figure 12Further comprising a supporting unit 400 arranged on the base 100, the supporting unit 400 comprises a third sliding rail 410 fixed on the base 100, a third sliding table 420 is slidingly arranged on the third sliding rail 410, one end of the third sliding rail 410 is provided with a third electric cylinder 430 for driving the third sliding table 420, the third sliding table 420 is fixed with a mounting table 440, one end of the mounting table 440 is rotatably connected with an arc-shaped bracket 450, and a coil spring is arranged at the rotating connection position of the arc-shaped bracket 450 and the mounting table 440; a plurality of arc-shaped grooves 460 are axially arranged in the arc-shaped bracket 450, a non-contact infrared temperature measuring ring 470 is arranged in each arc-shaped groove 460, and a cooling liquid nozzle 480 corresponding to each arc-shaped groove 460 is also arranged in the arc-shaped bracket 450; the arc-shaped bracket 450 is connected with a liquid delivery pipe 490 in communication with each cooling liquid nozzle 480;

[0092] Specifically, before turning processing, the roll 700 to be processed is placed on the arc-shaped bracket 450, the third sliding table 420 is driven to slide horizontally along the third sliding rail 410 by the third electric cylinder 430, so as to drive the arc-shaped bracket 450 on the mounting table 440 to move forward until the roll 700 is transferred to the position between the jacking unit 200 and the clamping driving unit 300, and then the roll 700 is clamped and fixed by the jacking unit 200 and the clamping driving unit 300; during the turning process, the different positions of the roll 700 are monitored by the plurality of groups of non-contact infrared temperature measuring rings 470 on the arc-shaped bracket 450, when the temperature of the corresponding area exceeds the set threshold value, the liquid delivery pipe 490 is controlled to be in conduction with the corresponding cooling liquid nozzle 480 by the controller, so as to spray cooling liquid on the area to cool it down; the plurality of groups of cooling liquid nozzles 480 are independent of each other and do not interfere with each other.

[0093] In addition, in the initial state, due to the elastic force of the coil spring, the arc-shaped bracket 450 is always turned upward and abuts against the end of the mounting table 440, so as to support the roll 700; when the turning is completed, the mounting table 440 is driven to retreat by the third electric cylinder 430, the arc-shaped bracket 450 is limited by the roll 700, so as to be able to deflect downward relative to the mounting table 440, to bypass the roll 700 from below, and then to be elastically turned upward again after the arc-shaped bracket 450 is completely separated from the roll 700.

[0094] It is worth noting that a plurality of arc-shaped grooves 460 are axially arranged in the arc-shaped bracket 450, and an independent non-contact infrared temperature measuring ring 470 is arranged in each arc-shaped groove 460, during the turning process, the non-contact infrared temperature measuring ring 470 can continuously and non-contactly monitor the temperature distribution of different axial positions of the roll 700, and provide direct data input for thermal deformation analysis and control (such as linkage sliding cylinder 220 compensation);

[0095] Cooling liquid injection ports 480 corresponding to the arc-shaped grooves 460 are arranged in the arc-shaped bracket 450, and each cooling liquid injection port 480 is independently supplied with liquid through a liquid supply pipe 490. When the non-contact infrared temperature measuring ring 470 in a certain area detects that the temperature exceeds a set threshold, the controller can individually control the cooling liquid injection port 480 in the corresponding area to be opened, and the cooling liquid can be accurately sprayed to the high-temperature point in a targeted and localized manner, so that the temperature can be quickly reduced. Compared with overall pouring cooling, the cooling efficiency is higher, the consumption of cooling liquid is reduced, and stress or cracks caused by uneven temperature drop can be avoided.

[0096] The arc-shaped bracket 450 is rotationally connected with the mounting table 440, and a coil spring is arranged to provide upward overturning torque. In the loading or standby state, the force of the coil spring keeps the arc-shaped bracket 450 in an upward overturned posture, and the arc-shaped bracket 450 stably supports the workpiece. In the unloading or back-off state, when the roller 700 needs to move backward and is still in the clamping position, the arc-shaped bracket 450 is forced to rotate downward around the shaft under the constraint of the roller 700 (overcoming the force of the coil spring), so that the entire bracket smoothly passes through the workpiece from below, and after completely separating from the constraint of the workpiece, the force of the coil spring immediately drives the arc-shaped bracket 450 to automatically overturn upward and reset to the initial posture.

[0097] The specific embodiments of the present application are described above, but the present application is not limited to the above specific embodiments. The above specific embodiments are only illustrative and not restrictive, and those skilled in the art can make many forms under the inspiration of the present application, which all belong to the protection of the present application.
