Description

Technical Field

[0001] This utility model belongs to the field of bar processing, and specifically relates to an automatic bar processing machine tool. Background Technology

[0002] In the fields of machinery manufacturing, hardware processing, and building materials, bar stock (such as metal round bars and plastic bars) is a commonly used basic raw material. During its processing, it often needs to be cut into multiple workpieces of equal length according to production needs to meet the dimensional requirements of subsequent machining, assembly and other processes.

[0003] Currently, the cutting of bar stock in the industry mainly relies on traditional cutting machines (such as abrasive wheel cutting machines, saw blade cutting machines, plasma cutting machines, etc.). The typical processing flow is as follows: the operator places the bar stock to be cut on the worktable or positioning frame of the cutting machine, manually measures and marks the cutting length using tools such as rulers and tape measures, starts the cutting machine to cut the first section of bar stock, and then manually controls the push plate to move the remaining bar stock along the feed direction so that the uncut part of the bar stock is re-aligned with the cutting position of the cutting machine. The dimensions are then confirmed again before the next cut can be carried out. This process of "cutting-manual pushing-confirmation-recutting" needs to be repeated until the entire bar stock is cut.

[0004] However, the aforementioned traditional bar cutting method has significant drawbacks: because each cut requires manual control of the pusher plate to feed the bar, and pauses are necessary during feeding to confirm the bar's positioning accuracy, the bar cutting operation cannot be continuous, remaining in a discontinuous state of "cutting-pause-feeding-pause-cutting." This intermittent processing mode significantly extends the overall cutting cycle of a single bar, and the problem of low processing efficiency becomes even more prominent when facing batch bar cutting needs, making it difficult to adapt to the capacity requirements of modern production scenarios. Utility Model Content

[0005] In view of this, the present invention provides an automatic bar stock processing machine tool to solve the problem in the prior art that the bar stock must be fed by manually controlling the push plate after each cutting.

[0006] The technical solution adopted in this utility model is as follows: An automatic bar stock processing machine tool includes a worktable with a limiting assembly. The limiting assembly includes two limiting posts spaced apart at the top of the worktable, forming a limiting space between the two limiting posts for the bar stock to pass through. A crossbeam is provided above the worktable, and a cutting machine is mounted on the crossbeam. A guide rail is vertically provided on one side of the worktable, and a slide rail that slides with the guide rail is provided on the crossbeam. A lifting device is also provided on one side of the worktable, and the lifting device is connected to the crossbeam. A push plate is slidably connected to the top of the workbench. The push plate is connected to the slide rail via a linkage device. When the slide rail moves upward, the push plate moves along the length of the workbench via the linkage device, thereby moving the bar stock.

[0007] In this technical solution, it should be noted that the workbench provides a basic support platform for the entire equipment, supporting all components, and has a length of 200cm-300cm; the two limiting posts of the limiting component are spaced apart, forming a limiting space to constrain the movement direction of the bar stock and prevent lateral deviation during feeding; the crossbeam supports the cutting machine and provides a foundation for its installation and movement; the guide rail slides with the slide rail on the crossbeam, providing guidance for the up-and-down movement of the crossbeam and ensuring smooth movement; the lifting device drives the crossbeam to move up and down along the guide rail, controlling the cutting machine's approach or departure from the bar stock; the push plate directly pushes the bar stock along the length of the workbench; the linkage device converts the up-and-down movement of the slide rail into the horizontal movement of the push plate, realizing the motion transmission of crossbeam lifting and bar stock feeding. Working Principle: When bar cutting is required, the bar is placed into the limiting space formed by two limiting posts. The lifting device starts, driving the crossbeam (along with the slide rail and cutting machine) to move upward along the guide rail. During the upward movement of the slide rail, the push plate moves along the length of the worktable through the linkage device. The push plate pushes the bar to move stably within the limiting space to the cutting position. Subsequently, the lifting device drives the crossbeam to move downward, and the cutting machine on the crossbeam approaches the bar and completes the cutting operation. During the cutting process, the slide rail moves downward with the crossbeam, and the linkage device does not drive the push plate to move, ensuring the stability of the bar position. In this utility model, by setting the limiting components, the bar feed direction is effectively constrained, avoiding bar deviation that affects cutting accuracy. The linkage device links the lifting movement of the crossbeam with the feed movement of the push plate, realizing the coordinated operation of bar feed and cutting action. There is no need for manual pushing of the bar, reducing manual intervention and improving cutting efficiency.

[0008] Preferably, two mounting plates are spaced apart on the side wall of the workbench. The linkage device includes a screw, a gear, and a rack. The two ends of the screw are rotatably connected to the two mounting plates respectively. The push plate is threadedly connected to the screw. The gear is fixedly sleeved on one end of the screw through a one-way bearing. The rack is mounted on the slide rail, and the rack and gear mesh with each other.

[0009] In this technical solution, it should be noted that two mounting plates are fixed at intervals to the side wall of the worktable to provide end support for the screw and ensure its stable rotation. The screw is connected to the push plate, and its rotation can drive the push plate to move along the length of the worktable. The gear and rack mesh with each other to convert the up-and-down movement of the slide rail into the rotational motion of the gear. The one-way bearing is an existing technology, which is sleeved between the screw and the gear. It has rolling elements and inner and outer rings inside, which can realize the one-way power transmission between the gear and the screw. That is, the gear drives the screw to rotate synchronously only when it rotates in a specific direction (clockwise), and does not transmit power when it rotates in the opposite direction (counterclockwise). Working principle: When the lifting device moves the slide rail upward, the rack on the slide rail moves upward synchronously. The rack drives the meshing gear to rotate clockwise. At this time, the inner and outer rings of the one-way bearing are engaged by the rolling elements and are in a locked state. The gear drives the screw to rotate synchronously. The rotation of the screw drives the push plate to move along the length of the worktable, realizing the feeding of the bar stock. When the lifting device moves the slide rail downward, the rack moves downward synchronously, driving the gear to rotate counterclockwise. At this time, the rolling elements of the one-way bearing are disengaged, and the inner and outer rings rotate relative to each other. The gear cannot drive the screw to rotate, and the push plate remains stationary, ensuring that the bar stock does not move during the cutting process. Effect: By setting up a gear with a one-way bearing, and a meshing rack and screw, the one-way transmission characteristic of the one-way bearing is utilized to realize that the push plate only feeds in one direction when the slide rail moves upward. During the cutting process (when the slide rail moves downward), the push plate does not move, ensuring the stability of the bar stock position during cutting.

[0010] Preferably, the rack is detachably mounted on the slide rail by bolts.

[0011] In this technical solution, it should be noted that the bolts are used to connect and fix the rack to the slide rail, while also enabling the rack and slide rail to be detachably assembled, facilitating the removal of the rack as needed. During normal cutting operations, the rack is securely installed on the slide rail with the bolts. The rack moves up and down with the slide rail, meshing with the gear to achieve unidirectional feeding of the push plate. When a bar stock is cut and the push plate needs to be reset, the bolts are unscrewed to remove the rack from the slide rail, disengaging the rack from the gear. At this time, the screw is rotated to make it rotate in the opposite direction, driving the push plate to return to its initial position along the length of the worktable. After reset, the rack is reinstalled on the slide rail with the bolts, and the next bar stock can be cut.

[0012] Preferably, a handwheel is provided at the end of the screw away from the gear.

[0013] In this technical solution, it should be noted that a handwheel is provided to enable manual drive for the push plate to reset.

[0014] Preferably, a movable seat is slidably connected to the crossbeam, the cutting machine is mounted on the movable seat, a lead screw is rotatably connected to the crossbeam, a slide seat is provided on the movable seat and threadedly connected to the lead screw, a motor is provided at one end of the crossbeam, and the output end of the motor is fixedly connected to the lead screw.

[0015] In this technical solution, it should be noted that when the cutting position of the cutting machine needs to be adjusted to adapt to bars of different specifications or positions, the motor is started, the output end of the motor drives the lead screw to rotate, the lead screw drives the slide to move along the length of the crossbeam through the thread transmission, the moving seat drives the cutting machine on it to move synchronously until the cutting machine moves to the preset cutting position, the motor stops working, the cutting machine position is fixed and the cutting operation is carried out.

[0016] Preferably, there are multiple sets of limiting components, which are spaced apart along the width direction of the worktable, and the diameter of the limiting post of each set of limiting components is different.

[0017] In this technical solution, it should be noted that by setting multiple sets of limiting components with different diameter limiting columns, it is possible to quickly adapt to the cutting of bar stock of various diameter specifications without disassembling or replacing the limiting components, thereby reducing equipment changeover time and improving the adaptability to processing bar stock of various specifications. The moving seat can be driven to the top of different limiting components by a lead screw.

[0018] Preferably, the top and bottom of the limiting post are respectively provided with limiting discs, and the diameter of the limiting discs is larger than the diameter of the limiting post.

[0019] In this technical solution, it should be noted that when the bar stock is placed within the limiting space formed by the two limiting posts, the upper and lower sides of the bar stock are close to the limiting plates at the top and bottom of the limiting posts, respectively. During the feeding of the bar stock along the length of the worktable by the pusher plate and the cutting process by the cutting machine, the limiting plates block the bar stock from the upper and lower directions, preventing the bar stock from shifting vertically due to vibration, feeding force, or cutting force, and ensuring that the bar stock always maintains a stable posture within the limiting space. Effect: By setting limiting plates at the top and bottom of the limiting posts, the bar stock is limited in the upper and lower directions, supplementing the limitation of the limiting posts only constraining the lateral direction, achieving stable constraint of the bar stock in three dimensions; effectively preventing the bar stock from moving vertically or escaping the limiting space.

[0020] Preferably, slide rails are provided on both sides of the crossbeam, the lifting device is a cylinder, the piston rod of the cylinder is connected to the crossbeam, and the two slide rails are symmetrically arranged on both sides of the cylinder.

[0021] In this technical solution, it should be noted that by setting symmetrical slide rails on both sides of the crossbeam, and using cylinders as lifting devices, with the slide rails symmetrically distributed on both sides of the cylinders (the cylinders adopt existing technology, supplying and discharging air through an external air pump), the stable power output of the cylinders ensures that the crossbeam is subjected to balanced force during lifting and lowering. The slide rails on both sides slide synchronously along the guide rails, effectively preventing the crossbeam from tilting, ensuring the accuracy of the cutting machine's up and down movement, and avoiding deviations in the cutting position due to crossbeam tilting. The linear motion characteristics of the cylinders simplify the lifting transmission structure, improve the controllability of the crossbeam's lifting speed and position, and further enhance the stability and reliability of the cutting process.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a limiting component, the feeding direction of the bar stock is effectively constrained, and the bar stock deviation is avoided from affecting the cutting accuracy; by using a linkage device to link the lifting motion of the crossbeam with the feeding motion of the push plate, the bar stock feeding and cutting action are coordinated, eliminating the need for manual pushing of the bar stock, reducing manual intervention, and improving cutting efficiency; 2. In this utility model, by setting a gear with a one-way bearing, a meshing rack and screw, and utilizing the one-way transmission characteristics of the one-way bearing, the push plate is fed in one direction only when the slide rail moves upward. During the cutting process (when the slide rail moves downward), the push plate does not move, ensuring the stability of the bar stock during cutting. 3. In this utility model, by setting multiple sets of limiting components with different diameter limiting columns, it is possible to quickly adapt to the cutting of bar stock of various diameter specifications without disassembling or replacing the limiting components, thereby reducing equipment changeover time and improving the adaptability to processing bar stock of various specifications. The moving seat can be driven to the top of different limiting components by a lead screw. Attached Figure Description

[0030] Example 1 like Figures 1-6As shown in the figure, an automatic bar stock 300 processing machine tool is disclosed in this embodiment of the utility model, including a worktable 100. The worktable 100 is provided with a limiting component, which includes two limiting posts 200 spaced apart at the top of the worktable, forming a limiting space between the two limiting posts 200 for the bar stock 300 to pass through. A crossbeam 400 is provided above the worktable 100, and a cutting machine 500 is provided on the crossbeam 400. A guide rail 800 is vertically provided on one side of the worktable 100, and a slide rail 401 is provided on the crossbeam 400 that slides with the guide rail 800. A lifting device is also provided on one side of the worktable 100, and the lifting device is connected to the crossbeam 400. A push plate 600 is slidably connected to the top of the worktable, and the push plate 600 is connected to the slide rail 401 through a linkage device. When the slide rail 401 moves upward, the push plate 600 is driven to move along the length direction of the worktable 100 through the linkage device, so as to move the bar stock 300. It should be noted that the workbench 100 provides a basic support platform for the entire equipment, bearing all components, and is 200cm-300cm in length; the two limiting posts 200 of the limiting component are spaced apart, forming a limiting space to constrain the movement direction of the bar stock 300 and prevent the bar stock 300 from shifting laterally during feeding; the crossbeam 400 supports the cutting machine 500, providing a base for its installation and movement; the guide rail 800 slides in conjunction with the slide rail 401 on the crossbeam 400, providing guidance for the up-and-down movement of the crossbeam 400 and ensuring smooth movement; the lifting device drives the crossbeam 400 to move up and down along the guide rail 800, controlling the approach or distance between the cutting machine 500 and the bar stock 300; the push plate 600 directly pushes the bar stock 300 along the length of the workbench 100; the linkage device converts the up-and-down movement of the slide rail 401 into the horizontal movement of the push plate 600, realizing the motion transmission of the lifting of the crossbeam 400 and the feeding of the bar stock 300. Working principle: When bar stock 300 needs to be cut, the bar stock 300 is placed in the limiting space formed by the two limiting posts 200. The lifting device is activated, driving the crossbeam 400 (along with the slide rail 401 and the cutting machine 500) to move upward along the guide rail 800. During the upward movement of the slide rail 401, the push plate 600 is driven to move along the length of the worktable 100 through the linkage device. The push plate 600 pushes the bar stock 300 to move stably to the cutting position within the limiting space. Subsequently, the lifting device drives the crossbeam 400 to move downward. The cutting machine 500 on the crossbeam 400 approaches the bar stock 300 and completes the cutting operation. During the cutting process, the slide rail 401 moves downward with the crossbeam 400. The linkage device does not drive the push plate 600 to move, ensuring that the position of the bar stock 300 is stable.In this invention, by setting a limiting component, the feeding direction of the bar stock 300 is effectively constrained, preventing the bar stock 300 from deviating and affecting the cutting accuracy; by using a linkage device to link the lifting motion of the crossbeam 400 with the feeding motion of the push plate 600, the feeding of the bar stock 300 and the cutting action are coordinated, eliminating the need for manual pushing of the bar stock 300, reducing manual intervention and improving cutting efficiency.

[0031] Example 2 like Figures 3-4 As shown, this embodiment is largely the same as the above embodiment, except that two mounting plates 701 are spaced apart on the side wall of the workbench 100. The linkage device includes a screw 700, a gear 703 and a rack 702. The two ends of the screw 700 are rotatably connected to the two mounting plates 701 respectively. The push plate 600 is threadedly connected to the screw 700. The gear 703 is fixedly sleeved on one end of the screw 700 through a one-way bearing 704. The rack 702 is mounted on the slide rail 401, and the rack 702 and the gear 703 mesh with each other. It should be noted that the two mounting plates 701 are fixed at intervals on the side wall of the worktable 100 to provide end support for the screw 700 and ensure its stable rotation. The screw 700 is connected to the push plate 600, and its rotation can drive the push plate 600 to move along the length of the worktable 100. The gear 703 meshes with the rack 702 to convert the up-and-down movement of the slide rail 401 into the rotational movement of the gear 703. The one-way bearing 704 is existing technology and is sleeved between the screw 700 and the gear 703. It has rolling elements and inner and outer rings inside, which can realize the one-way power transmission between the gear 703 and the screw 700. That is, the gear 703 drives the screw 700 to rotate synchronously only when it rotates in a specific direction (clockwise), and does not transmit power when it rotates in the opposite direction (counterclockwise). Working principle: When the lifting device moves the slide rail 401 upward, the rack 702 on the slide rail 401 moves upward synchronously. The rack 702 drives the meshing gear 703 to rotate clockwise. At this time, the inner and outer rings of the one-way bearing 704 are engaged by rolling elements and are in a locked state. The gear 703 drives the screw 700 to rotate synchronously. The rotation of the screw 700 drives the push plate 600 to move along the length of the worktable 100, realizing the feeding of the bar stock 300. When the lifting device moves the slide rail 401 downward, the rack 702 moves downward synchronously, driving the gear 703 to rotate counterclockwise. When the rolling elements of the one-way bearing 704 disengage, the inner and outer rings rotate relative to each other, the gear 703 cannot drive the screw 700 to rotate, and the push plate 600 remains stationary, ensuring that the bar stock 300 does not move during the cutting process; Effect: By setting up a gear 703 with a one-way bearing 704, a meshing rack 702 and a screw 700, and utilizing the one-way transmission characteristic of the one-way bearing 704, the push plate 600 is only fed in one direction when the slide rail 401 moves upward. During the cutting process (when the slide rail 401 moves downward), the push plate 600 does not move, ensuring the stable position of the bar stock 300 during cutting.

[0032] like Figure 3 As shown, in this embodiment, the rack 702 is detachably mounted on the slide rail 401 by bolts. It should be noted that the bolts are used to connect and fix the rack 702 to the slide rail 401, while also enabling the rack 702 and slide rail 401 to be detachably assembled, facilitating the removal of the rack 702 as needed. During normal cutting operations, the rack 702 is securely mounted on the slide rail 401 with bolts. The rack 702 moves up and down with the slide rail 401, meshing with the gear 703 to achieve unidirectional feeding of the push plate 600. When the push plate 600 needs to be reset after cutting a bar stock 300, the bolts are unscrewed to remove the rack 702 from the slide rail 401, disengaging the rack 702 from the gear 703. At this time, the screw 700 is rotated to rotate in the opposite direction, driving the push plate 600 to return to its initial position along the length of the worktable 100. After resetting, the rack 702 is remounted on the slide rail 401 with bolts, and the next bar stock 300 can be cut.

[0033] like Figure 3 As shown, in this embodiment, a handwheel is provided at the end of the screw 700 away from the gear 703. It should be noted that the handwheel provides a manual drive for resetting the push plate 600.

[0034] Example 3 like Figure 5 As shown, this embodiment is largely the same as the previous embodiment, except that a movable seat 404 is slidably connected to the crossbeam 400, the cutting machine 500 is mounted on the movable seat 404, a lead screw 402 is rotatably connected to the crossbeam 400, a slide block 403 is provided on the movable seat 404 and threadedly connected to the lead screw 402, and a motor is provided at one end of the crossbeam 400, the output end of the motor is fixedly connected to the lead screw 402. It should be noted that when the cutting position of the cutting machine 500 needs to be adjusted to accommodate bar stock 300 of different specifications or positions, the motor is started, the motor output end drives the lead screw 402 to rotate, the lead screw 402 drives the slide block 403 to move along the length of the crossbeam 400 through threaded transmission, the movable seat 404 drives the cutting machine 500 on it to move synchronously until the cutting machine 500 moves to the preset cutting position, the motor stops working, the cutting machine 500 is fixed in position and performs cutting operations.

[0035] Example 4 like Figure 1As shown, this embodiment is largely the same as the above embodiment, except that there are multiple sets of limiting components. These multiple sets of limiting components are spaced apart along the width direction of the worktable 100, and the diameter of the limiting post 200 in each set of limiting components is different. It should be noted that by setting multiple sets of limiting components with different diameters of limiting post 200, it is possible to quickly adapt to the cutting of bar stock 300 of various diameters without disassembling or replacing the limiting components, reducing equipment changeover time and improving the adaptability to processing bar stock 300 of various specifications. The movable seat 404 can be driven above the different limiting components by the lead screw 402.

[0036] like Figure 6 As shown, in this embodiment, the top and bottom of the limiting post 200 are respectively provided with limiting disks 201, and the diameter of the limiting disks 201 is larger than the diameter of the limiting post 200. It should be noted that when the bar stock 300 is placed in the limiting space formed by the two limiting posts 200, the upper and lower sides of the bar stock 300 are close to the limiting disks 201 at the top and bottom of the limiting post 200, respectively. During the process of the push plate 600 pushing the bar stock 300 to feed along the length direction of the worktable 100 and the cutting machine 500 cutting, the limiting disks 201 block the bar stock 300 from the upper and lower directions to prevent the bar stock 300 from shifting vertically due to vibration, feeding force or cutting force, and ensure that the bar stock 300 always maintains a stable posture within the limiting space. Effect: By setting limiting plates 201 at the top and bottom of the limiting post 200, the bar stock 300 is limited in the vertical direction, which makes up for the deficiency of the limiting post 200 which only constrains the horizontal direction, and realizes the stable constraint of the bar stock 300 in the three-dimensional direction; effectively preventing the bar stock 300 from moving up and down or leaving the limiting space.

[0037] Example 5 like Figure 2 As shown, this embodiment is largely the same as the above embodiment, except that slide rails 401 are provided on both sides of the crossbeam 400, the lifting device is a cylinder 900, the piston rod 901 of the cylinder 900 is connected to the crossbeam 400, and the two slide rails 401 are symmetrically arranged on both sides of the cylinder 900. It should be noted that by setting symmetrical slide rails 401 on both sides of the crossbeam 400, and using cylinders 900 as lifting devices, and with the slide rails 401 symmetrically distributed on both sides of the cylinders 900 (which use existing technology and are supplied and discharged by an external air pump), the stable power output of the cylinders 900 ensures that the crossbeam 400 is subjected to balanced force during lifting. The slide rails 401 on both sides slide synchronously along the guide rails 800, effectively preventing the crossbeam 400 from tilting, ensuring the accuracy of the cutting machine 500's up and down movement, and avoiding cutting position deviations caused by the tilting of the crossbeam 400. The linear motion characteristics of the cylinders 900 simplify the lifting transmission structure, improve the controllability of the lifting speed and position of the crossbeam 400, and further enhance the stability and reliability of the cutting process.

[0038] The working principle of this utility model is as follows: When cutting bar stock 300, first select the corresponding limiting component according to the diameter of bar stock 300, and place bar stock 300 into the limiting space formed by two limiting posts 200, with the upper and lower sides of bar stock 300 close to the limiting plates 201 above and below the limiting posts 200. When it is necessary to adjust the lateral position of cutting machine 500, start the motor at one end of crossbeam 400. The motor drives screw 402 to rotate. Screw 402 drives moving seat 404 and cutting machine 500 to the preset position through slide block 403, and then the motor stops. Then cylinder 900 starts, piston rod 901 extends and drives crossbeam 400 to move upward along slide rails 401 on both sides. The rack 702 on slide rail 401 moves upward synchronously, driving gear 703 to rotate clockwise. Gear 703 drives screw 700 to rotate through one-way bearing 704. Push plate 600 slides along worktable 100 with screw 700 as screw rotates, pushing bar stock 300 to the cutting position within the limiting space. Next, the piston rod 901 of cylinder 900 retracts, causing the crossbeam 400 to move downwards. The cutting machine 500 approaches the bar stock 300 to complete the cut. At this time, the rack 702 moves downwards with the crossbeam 400, causing the gear 703 to rotate counterclockwise. The one-way bearing 704 prevents the gear 703 from driving the screw 700 to rotate, and the push plate 600 remains stationary. The process of the crossbeam 400 rising to push the material and falling to cut is repeated until the entire bar stock 300 is cut. After one bar stock 300 is cut, the bolt is unscrewed to remove the rack 702. The handwheel at the other end of the screw 700 is rotated to drive the screw 700 to rotate in the opposite direction, causing the push plate 600 to return to its initial position. Then, the rack 702 is reinstalled into the slide rail 401 with bolts, and the next bar stock 300 can be cut.
