Description

Technical Field

[0001] This invention relates to the field of sawing technology, specifically to a sawing device for tire mold production. Background Technology

[0002] Sawing refers to the process of using a sawing machine to cut raw materials (such as bars, tubes, profiles, or billets) into the required lengths according to pre-set dimensions and shapes. It is a common preliminary processing step in industries such as machining and mold making, providing precise blank materials for subsequent processes such as forging, heat treatment, and machining.

[0003] In tire mold production, sawing is usually used to cut blanks to a specified length. It is necessary to select materials, control precision, and ensure safe operation in accordance with mold design requirements. This is a key link to ensure the accuracy of subsequent processing and the quality of the mold.

[0004] Existing sawing devices used in tire mold production typically clamp and fix the horizontally placed annular steel billet on both sides using fixtures, move the cutting component to the corresponding position, and cut the annular steel billet from top to bottom using the cutting component. Although this cutting method can achieve the cutting operation of the annular steel billet, the cutting component needs to cut from one side of the annular steel billet to the other side, which takes a long time and has low cutting efficiency. Moreover, since the annular steel billet is in a fixed state, the cutting component may be affected by resistance during the cutting process and shift, affecting the flatness of the cut surface, thereby increasing the allowance for subsequent processing and reducing the production efficiency of tire molds.

[0005] Therefore, there is a need to provide a sawing device for tire mold production, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a sawing device for tire mold production, so as to solve the problems in the background art.

The second threaded cylinder and several sliding racks are movably connected by several hinge rods.

[0024] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0025] 1. In this invention, the lower sidewall of the steel billet can be supported by the moving rod assembly and the abutment assembly. The height of the support roller group can be adjusted by adjusting the extension and retraction of the first electric cylinder, so that the rotation axis of the steel billet is collinear with the rotation axis of the arc-shaped groove. The first spring pushes the abutment cone block close to the end of the steel billet, so that the abutment cone block abuts against the end of the steel billet, which facilitates the subsequent stable rotational sawing of the steel billet, helps to reduce the descent of the sawing assembly, and improves the sawing efficiency.

[0026] 2. In this invention, the sawing assembly and the gantry frame can adjust the sawing thickness of the steel billet by driving the reciprocating sawing module to move synchronously, thereby meeting the sawing requirements of different thicknesses and improving the applicability of the device. The sawing motor drives the rotating cam to rotate. The rotating cam drives the saw blade to move in the horizontal direction by contacting the saw blade and sliding the sliding column and the cross groove. At the same time, the saw blade is also moving downward, which can perform stable sawing operation on the steel billet.

[0027] 3. In this invention, through the clamping assembly, several first clamping blocks clamp the outer wall of the steel billet by abutting against it. The first moving seat is in a fixed state. At this time, the second threaded cylinder continues to move away from the rotating disk. The second threaded cylinder drives the sliding rack to move towards the center of the movable side plate by being movably connected to the hinge rod. Several second clamping blocks can position the inner wall of the steel billet by abutting against it, thereby achieving dual positioning of the outer and inner walls of the steel billet.

[0028] 4. In this invention, after the end of the steel billet is clamped, the rotary motor drives the rotary gear to rotate. The rotary gear meshes with the gear ring and the rotating disk rotates with the movable side plate, causing the clamping assembly to rotate synchronously. The clamping assembly rotates the steel billet by contacting it. The sawing assembly can uniformly saw the steel billet by cooperating with the rotating steel billet, which can effectively ensure that the cut surface of the steel billet is flat, reduce the subsequent processing allowance, and improve the utilization rate of materials. At the same time, the sawing depth only needs to reach the outer radius of the steel billet, without having to move the saw blade to the bottom of the steel billet, which helps to improve the sawing efficiency of the steel billet and reduce the sawing time.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0049] In one embodiment of the present invention, see Figure 1-Figure 2A sawing device for producing tire molds includes a worktable 1, a base 101 at one end of the worktable 1, a movable component 2 for placing a steel billet 8 movably mounted on the worktable 1, an abutting component 3 movably abutting one end of the steel billet 8 on the movable component 2, a sawing component 4 for sawing the steel billet 8 movably mounted on one end of the worktable 1, a flipping component 5 mounted on the base 101, the flipping component 5 being located on the side of the sawing component 4 away from the abutting component 3, a rotating component 6 movably mounted on the flipping component 5, and a clamping component 7 for clamping the end of the steel billet 8 on the rotating component 6.

[0050] In this embodiment, the moving component 2 can move the steel billet 8. The abutting component 3 can abut the end of the steel billet 8 away from the sawing component 4, preventing the steel billet 8 from shifting during the sawing process and improving the sawing stability. The clamping component 7 can provide multiple stable clamps to the end of the steel billet 8 away from the abutting component 3, which can meet the clamping requirements of steel billets 8 of different sizes. At the same time, it can meet the clamping requirements of nested steel billets 8 of different sizes. The sawing component 4 can flexibly adjust the sawing position to meet the sawing requirements of tire molds of different thicknesses. Through the cooperation of the sawing component 4 and the rotating component 6, the steel billet 8 can be rotated and sawed evenly, ensuring that the cut surface of the steel billet 8 is flat, reducing subsequent processing allowances, and improving material utilization.

[0051] In one embodiment of the present invention, see Figures 1-3 The moving component 2 includes a first screw 202 rotatably disposed on the inner side of the workbench 1. One end of the first screw 202 is connected to a moving motor 201 mounted on the side wall of the workbench 1. A first guide rod 203 is provided on the inner side of the workbench 1. A support seat 204 threadedly connected to the first screw 202 is movably disposed on the inner side of the workbench 1. The support seat 204 is slidably engaged with the first guide rod 203. The support seat 204 is provided with a plurality of arc-shaped grooves for placing steel billets 8. A plurality of support roller groups 205 that contact the outer wall of the outer side of the steel billet 8 are movably disposed in the arc-shaped grooves. The support roller groups 205 and the arc-shaped grooves are connected by a first electric cylinder 206.

[0052] The abutment component 3 includes a first mounting bracket 301 installed on the side of the support base 204 away from the sawing component 4. A plurality of movable rods 302 are movably mounted on the first mounting bracket 301. The rotation axis of the movable rods 302 is collinear with the rotation axis of the arc-shaped groove provided on the support base 204. The end of the movable rod 302 near the support base 204 is connected to an abutment cone block 305 that abuts against the end of the billet 8. The end of the movable rod 302 away from the abutment cone block 305 is connected to a limit ring 303. A first spring 304 sleeved on the outside of the movable rod 302 is connected between the first mounting bracket 301 and the abutment cone block 305.

[0053] In this embodiment, several steel billets 8 are placed in corresponding arc-shaped grooves, and several support roller groups 205 can support the lower sidewall of the steel billets 8. The height of the support roller groups 205 is adjusted by adjusting the extension and retraction of the first electric cylinder 206, so that the rotation axis of the steel billet 8 is collinear with the rotation axis of the arc-shaped groove. The first spring 304 pushes the abutting cone 305 close to the end of the steel billet 8, so that the abutting cone 305 abuts against the end of the steel billet 8, which can support one end of the steel billet 8. The movement distance of the movable rod 302 can be limited by the limiting ring 303.

[0054] The abutting cone 305 is configured as a cone-shaped frustum, with the end of the abutting cone 305 having a smaller cross-sectional dimension close to the steel billet 8, thereby enabling stable abutment of steel billets 8 of different sizes.

[0055] In one embodiment of the present invention, see Figure 1-Figure 5 The sawing assembly 4 includes side frames 401 symmetrically arranged on both sides of the workbench 1. A second screw 402 is rotatably mounted inside one side frame 401, and the second screw 402 is connected to an adjusting motor 403 installed on the outside of the side frame 401. A second guide rod 404 is mounted inside the other side frame 401. A gantry frame 405 is slidably mounted on the two side frames 401. One end of the gantry frame 405 is threadedly connected to the second screw 402, and the other end of the second screw 402 is slidably engaged with the second guide rod 404. The bottom of the gantry frame 405 is water-resistant. A horizontal plate 406 is provided. A third screw 407 is symmetrically and rotatably provided between the top of the gantry frame 405 and the horizontal plate 406. A first threaded cylinder 409 is threadedly connected to the third screw 407. A lifting motor 408 connected to one of the third screws 407 is installed on the top of the gantry frame 405. A transmission wheel 414 is provided on the top of the third screw 407. The two transmission wheels 414 are connected by a transmission belt 415. A reciprocating sawing module is provided between the two first threaded cylinders 409. A support module is provided on the horizontal plate 406.

[0056] The reciprocating sawing module includes a saw blade 410 movably disposed between two first threaded cylinders 409. One of the first threaded cylinders 409 is rotatably provided with a rotating cam 417 that is in movable contact with the end of the saw blade 410. The rotating cam 417 is connected to a sawing motor 416 disposed on the first threaded cylinder 409. The other first threaded cylinder 409 is provided with a plurality of transverse grooves 419. A sliding column 418 connected to the end of the saw blade 410 is slidably disposed in the transverse grooves 419.

[0057] The supporting module includes several support plates 411 that are movably arranged above the horizontal plate 406. Several columns 412 that penetrate the horizontal plate 406 are connected to the bottom of the support plates 411. Several second springs 413 that are sleeved on the outside of the columns 412 are connected between the horizontal plate 406 and the support plates 411.

[0058] In this embodiment, the bottom of several steel billets 8 can be effectively supported by the cooperation of the second spring 413 and the support plate 411. The adjusting motor 403 drives the second screw 402 to rotate. The second screw 402 drives the gantry frame 405 to move by means of threaded connection with the gantry frame 405 and sliding cooperation between the gantry frame 405 and the second guide rod 404. The gantry frame 405 can adjust the sawing thickness of the steel billet 8 by driving the reciprocating sawing module to move synchronously, thereby meeting the sawing requirements of different thicknesses and improving the applicability of the device.

[0059] The lifting motor 408 drives one of the third screws 407 to rotate. The third screw 407 drives the other third screw 407 to rotate synchronously through the transmission wheel 414 and the transmission belt 415. The third screw 407 drives the reciprocating sawing module to move down through the threaded connection with the first threaded cylinder 409.

[0060] The sawing motor 416 drives the rotary cam 417 to rotate. The rotary cam 417 drives the saw blade 410 to move horizontally through active contact with the saw blade 410 and sliding cooperation between the slide column 418 and the cross groove 419. At the same time, the saw blade 410 is also moving downward, which can perform stable sawing operation on the steel billet 8.

[0061] The saw blade 410 is set as a square frame at one end near the sawing motor 416. The rotating cam 417 is movably set inside the square frame. The rotating cam 417 drives the saw blade 410 to reciprocate horizontally by contacting the square frame and sliding with the sliding column 418 and the horizontal groove 419, thereby sawing the steel billet 8.

[0062] In one embodiment of the present invention, see Figures 1-9The flipping assembly 5 includes a rotating rod 503 disposed at one end of the workbench 1 near the base 101. A movable side plate 502 is movably disposed at one end of the workbench 1 near the base 101. Several connecting seats 504 are disposed at the bottom of the movable side plate 502, which are rotatably engaged with the rotating rod 503. Several second electric cylinders 501 are movably connected between the end of the base 101 away from the workbench 1 and the top of the movable side plate 502.

[0063] The rotating assembly 6 includes several rotating disks 601 rotatably mounted on the movable side plate 502. The rotating disks 601 are horizontally distributed. The outer side wall of each rotating disk 601 is provided with a toothed ring 602. A rotating gear 603 is movably mounted between two adjacent rotating disks 601 and meshes with the two adjacent toothed rings 602 respectively. One of the rotating gears 603 is connected to a rotating motor 604 mounted on the movable side plate 502.

[0064] The clamping assembly 7 includes a plurality of circumferentially formed sliding grooves 701 on the rotating disk 601. A first movable seat 708 and a second movable seat 710 are slidably provided at both ends of the sliding grooves 701, respectively. A first clamping block 7081 is provided at the end of the first movable seat 708 near the sawing assembly 4, and a second clamping block 7101 is provided at the end of the second movable seat 710 near the sawing assembly 4. An adjustment module is provided on the rotating disk 601 to cooperate with the plurality of first movable seats 708 and second movable seats 710.

[0065] The adjustment module includes a second mounting bracket 702 disposed on the rotary disk 601 away from the sawing assembly 4. A fourth screw 704 is rotatably connected between the sliding groove 701 and the second mounting bracket 702. The fourth screw 704 is connected to a clamping motor 703 mounted on the second mounting bracket 702. A second threaded cylinder 705 is threadedly connected to the fourth screw 704. A transmission gear 709 is rotatably provided at one end of the first movable seat 708 near the second mounting bracket 702. A sliding mechanism that slidably engages with the second movable seat 710 is slidably provided on the first movable seat 708. A rack 707 is provided, which meshes with a transmission gear 709. The bottom of the rack 707 is provided with a first stop 7071 and a second stop 7072 located on both sides of the first moving seat 708. A third spring 712 is connected between the first stop 7071 and the first moving seat 708. A side rack 711 is installed on the side wall of the second moving seat 710, which meshes with the end of the transmission gear 709 away from the rack 707. The second threaded cylinder 705 and several racks 707 are movably connected by several hinge rods 706.

[0066] In this embodiment, in the initial state, the movable side plate 502 is in a vertical state and the bottom of the movable side plate 502 is in contact with the top of the workbench 1. The extension distance of the second electric cylinder 501 is at its maximum distance. The corresponding first moving seat 708 and second moving seat 710 are far apart from each other. The second threaded cylinder 705 is close to the rotating disk 601. At this time, the included angle between the hinge rod 706 and the fourth screw 704 is at its maximum value. The second stop 7072 abuts against one end of the first moving seat 708, and the first stop 7071 is far away from the first moving seat 708.

[0067] Through the cooperation of the moving component 2 and the abutting component 3, the billet 8 can be pushed to the right, causing the end of the billet 8 away from the abutting component 3 to fit against the side wall of the rotating disk 601. At this time, the first moving seat 708 is located on the outside of the billet 8, and the second moving seat 710 is located on the inside of the billet 8. The clamping motor 703 drives the fourth screw 704 to rotate. The fourth screw 704 drives the second threaded cylinder 705 away from the rotating disk 601 by means of a threaded connection with the second threaded cylinder 705 and a movable connection between the second threaded cylinder 705 and several hinge rods 706 in fixed directions. The second threaded cylinder 705 moves away from the rotating disk 601 by means of a threaded connection with the second threaded cylinder 705 and a movable connection between the second threaded cylinder 705 and several hinge rods 706 in fixed directions. The sliding rack 707 moves toward the center of the movable side plate 502 by means of a movable connection with the hinge rod 706. The sliding rack 707 drives the first stop block 7071 to move synchronously. The first stop block 7071 moves toward the center of the rotating disk 601 by means of a connection with the third spring 712 and a sliding engagement between the first moving seat 708 and the sliding groove 701. The first moving seat 708 drives the corresponding first clamping block 7081 to move synchronously. Several first clamping blocks 7081 clamp the outer wall of the billet 8 by abutting against it.

[0068] When the first clamping block 7081 abuts against the steel billet 8, the first moving seat 708 is in a fixed state. At this time, the second threaded cylinder 705 continues to move away from the rotating disk 601. The second threaded cylinder 705 drives the sliding rack 707 to move towards the center of the movable side plate 502 through a movable connection with the hinge rod 706. The sliding rack 707 drives the first stop block 7071 to move synchronously. The third spring 712 is stressed and contracts. At the same time, the sliding rack 707 drives the transmission gear 709 to move through a meshing mechanism with the transmission gear 709. In response to the rotation, the transmission gear 709 meshes with the side rack 711 and the second moving seat 710 slides with the sliding groove 701 to drive the second moving seat 710 away from the center of the rotating disk 601. The second moving seat 710 drives the second clamping block 7101 to move synchronously by sliding outward along the sliding groove 701. Several second clamping blocks 7101 can position the inner wall of the steel billet 8 by abutting against the inner wall of the steel billet 8, thereby achieving dual positioning of the outer and inner walls of the steel billet 8.

[0069] After the end of the billet 8 is clamped, the rotary motor 604 drives the rotary gear 603 to rotate. The rotary gear 603 drives the clamping assembly 7 to rotate synchronously by meshing with the gear ring 602 and by rotating the rotary disk 601 and the movable side plate 502. The clamping assembly 7 drives the billet 8 to rotate by contacting it. The sawing assembly 4 can cut the billet 8 evenly by cooperating with the rotating billet 8, which can effectively ensure that the cut surface of the billet 8 is flat, reduce the subsequent processing allowance, and improve the utilization rate of materials. At the same time, the sawing depth only needs to reach the outer radius of the billet 8, without having to move the saw blade 410 to the bottom of the billet 8, which helps to improve the sawing efficiency of the billet 8 and reduce the sawing time.

[0070] After sawing is completed, the saw blade 410 moves upward, the second electric cylinder 501 retracts and drives the movable side plate 502 to rotate downward to a horizontal state through the rotation of the rotating rod 503 and the connecting seat 504. The movable side plate 502 drives the sawn steel billet 8 to rotate synchronously through the cooperation of the rotating component 6 and the clamping component 7. Then, the clamping component 7 releases the clamping of the sawn steel billet 8, making it easier for the workers to take out the sawn steel billet 8 for subsequent processing. Then, the second electric cylinder 501 extends and drives the movable side plate 502 to rotate upward to a vertical state through the rotation of the rotating rod 503 and the connecting seat 504, which facilitates the subsequent sawing operation of the steel billet 8.

[0071] The first clamping block 7081 and the second clamping block 7101 are both provided with convex arc surfaces on the side near the outer edge of the rotating disk 601, and the first clamping block 7081 and the second clamping block 7101 are both provided with concave arc surfaces on the side near the center of the rotating disk 601. By providing convex and concave arc surfaces, the stable clamping requirements of annular steel billets 8 of different sizes can be met. At the same time, by cooperating with several first clamping blocks 7081 and second clamping blocks 7101, steel billets 8 of different sizes can be clamped simultaneously, which improves the sawing efficiency and avoids the low efficiency caused by sawing different steel billets 8 separately.

[0072] At least three sliding grooves 701 are provided. By providing at least three sliding grooves 701, it is convenient to stably clamp the steel billet 8, thereby facilitating the uniform sawing of the steel billet 8.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
