Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, and in particular relates to a novel side discharge structure for bending machines. Background Art

[0002] The side discharge method commonly used on the bending machine is mainly to clamp the bent steel pipe through a steel plate clamp, which is connected to a chain, and then drives the sprocket chain through a gear reduction motor, thereby driving the steel plate clamp to pull the steel pipe out from the side of the bending machine.

[0003] However, due to the large size of this steel plate clamp, there is no clamping space for smaller steel pipes, especially for tapered steel pipes, and the steel plate clamp has no space to clamp the steel pipe. On the other hand, the support of the bent steel pipe is achieved by two hemispherical rollers, which are fixed on the bracket and can move left and right to achieve steel pipes of different sizes. However, since the steel plate clamp is installed between the two hemispherical rollers, the space is large and it is not suitable for supporting small-sized steel pipes. Utility Model Content

[0004] In order to solve the technical problem that when using steel plate calipers in a bending machine, space is limited and steel pipe discharge cannot be well realized in the background technology, the purpose of the utility model is to provide a new side discharge structure for a bending machine, which can solve the above problem.

[0005] The technical solution to achieve the purpose of the utility model is: a new side discharge structure for a bending machine, including a bending machine body and a slider and a workbench installed on the bending machine body, a connecting plate and a power device fixed on the slider, the power device is used to drive the connecting plate to slide on the slider, and a baffle is fixed on the connecting plate to push the workpiece on the workbench to move.

[0006] In this solution, a baffle is used to replace the steel plate caliper in the prior art. Specifically, a slider installed on the bending machine body is used as a carrier, and a connecting plate is slidably connected to the slider. The specific sliding structure can be of various types, and the positions of the slider and the workbench where the workpiece is placed can also be set in various ways. In this solution, the slider is located directly above the workbench as an example. A baffle is installed on the connecting plate, and the baffle is located on one side of the end of the workpiece. When the workpiece is processed and needs to be pushed out of the bending machine, the connecting plate slides on the slider and drives the baffle to push one end of the workpiece to the side of the bending machine, thereby pushing the workpiece out of the bending machine and completing the side discharge of the bending machine. This device eliminates the need to consider the space problem of the steel plate caliper, and solves the problem that the prior art cannot be used for the discharge of all steel pipe workpieces, especially small-sized steel pipe workpieces, due to insufficient space due to the existence of the steel plate caliper.

[0007] Furthermore, the slider is located above the workbench, an upper die is fixed on the slider, a lower die is fixed on the workbench, the slider is vertically slidably arranged on the bending machine body, and the upper die and the lower die are used to bend the workpiece after being clamped. In other words, the slider can slide vertically on the bending machine body, and the specific sliding structure will not be described in detail here. The slider drives the upper die and the lower die fixed on the workbench to cooperate to bend the workpiece, and the connecting plate can slide horizontally on the slider, driving the baffle to push the workpiece out of the bending machine from one side of the workpiece in the horizontal direction.

[0008] Furthermore, the baffle is located above the workbench. Since a workpiece needs to be placed above the workbench, when the connecting plate drives the baffle to slide horizontally on the slider and push the workpiece, the baffle needs to be located on one side of the end of the workpiece. At this time, the height of the baffle needs to be higher than the workbench, but not higher than the highest point of the end of the workpiece, so that the workpiece can be pushed from one end of the bending machine to the other end for side discharge.

[0009] Furthermore, the slider is provided with a linear guide rail, and the connecting plate is provided with a slide groove corresponding to the linear guide rail. The connecting plate slides on the slider through the cooperation of the linear guide rail and the slide groove, and drives the baffle connected to the connecting plate to push the workpiece in the horizontal direction to discharge from the side of the bending machine.

[0010] Furthermore, a rack is fixed on the slider, and the power device includes a motor, a reducer and a rotating shaft. The motor is installed on the reducer, and the reducer is fixed on the connecting plate. One end of the rotating shaft is connected to the reducer, and the other end of the rotating shaft is connected to a gear matched with the rack. The motor drives the reducer and drives the rotating shaft to rotate, and the rotating shaft drives the gear to rotate. The reducer is fixed on the connecting plate, so the connecting plate can be driven to slide by the coordinated rotation of the gear and the rack, so as to drive the connecting plate to slide horizontally on the slide.

[0011] Furthermore, the discharging mechanism also includes a conveying device for conveying workpieces, the conveying device includes a plurality of conveying units, the conveying units include rollers, the rollers in two oppositely arranged conveying units are tilted and assembled into a "V-shaped" structure, and a plurality of the "V-shaped" structures are assembled into a "V-shaped" channel, and the workpiece is conveyed in the "V-shaped" channel. Two adjacent conveying units are placed horizontally, and the two corresponding rollers are tilted inward, and the outer ends are tilted upward to form a shape such as a "V-shaped" structure, and then the rollers of two conveying units are assembled into a shape such as a "V-shaped" structure at intervals, so that a plurality of the "V-shaped" structures are assembled into a "V-shaped" channel, and the workpiece, such as a steel pipe, can be conveyed and transported in the "V-shaped" channel.

[0012] Furthermore, the conveying unit further includes a support rod and a bracket, one end of the support rod is hinged to the bracket, and the other end of the support rod is hinged to the roller. The bracket is responsible for supporting the entire conveying device and can be fixed by bolts. The support rod hinged structure can facilitate the tilting setting of the roller, and further the tilting angle can be adjusted according to the size of the workpiece, that is, the size of the "V-shaped" channel can be adjusted.

[0013] Furthermore, the support rod is hinged on one end of the roller, and the other end of the roller is hinged to the bracket, that is, both ends of the roller are connected in a hinged manner. Compared with the support of only the support rod, both ends have hinged support force, which will be more stable. When conveying workpieces, the "V-shaped" channel formed has stronger support force.

[0014] Furthermore, the conveying unit further includes a roller seat, a connecting shaft is fixed on the roller seat, and the roller is rotatably mounted on the connecting shaft; the roller seat is also provided with a connecting ear, and the roller and the support rod and the bracket are all hingedly connected through the connecting ear. Since the roller needs to rotate to better convey the workpiece, the roller is fixed on the connecting shaft for rotation, and the connecting shaft can be fixed on the roller seat; the connection ear is also provided to facilitate hinge connection, and specifically, a perforation can be provided on the connection ear to facilitate the connection of the hinge device.

DETAILED DESCRIPTION

[0030] Example:

[0031] like Figure 1-Figure 3As shown, this embodiment provides a new side discharge structure for a bending machine, including a bending machine body 1 and a slider 2 and a workbench 3 installed on the bending machine body 1. A connecting plate 4 and a power device 5 are fixed to the slider 2. The power device 5 is used to drive the connecting plate 4 to slide on the slider 2. A baffle 6 for pushing the workpiece 9 on the workbench 3 is fixed to the connecting plate 4. In this solution, the baffle 6 is used to replace the steel plate caliper in the prior art. Specifically, the slider 2 installed on the bending machine body 1 is used as a carrier, and the connecting plate 4 is slidably connected to the slider 2. The specific sliding structure can be multiple, and the positions of the slider 2 and the workbench 3 on which the workpiece 9 is placed can also be set in multiple ways. In this solution, the slider 2 is located directly above the workbench 3 as an example. The connecting plate 4 is provided with a baffle 6, which is located at one side of the end of the workpiece 9. When the workpiece 9 is processed and needs to be pushed out of the bending machine, the connecting plate 4 slides on the slider 2 and drives the baffle 6 to push one end of the workpiece 9 to the side of the bending machine, thereby pushing the workpiece 9 out of the bending machine and completing the side discharging of the bending machine. The device eliminates the need to consider the space problem of the steel plate caliper, and solves the problem that the existing technology cannot be applied to the discharging of all steel pipe workpieces 9, especially the discharging of small-sized steel pipe workpieces 9, due to the insufficient space of the steel plate caliper.

[0032] like Figure 3 As shown, the slider 2 is located above the workbench 3, an upper die 7 is fixed on the slider 2, a lower die 8 is fixed on the workbench 3, and the slider 2 is vertically slidably arranged on the bending machine body 1. The upper die 7 and the lower die 8 are used to bend the workpiece 9 after the upper die 7 and the lower die 8 are closed. In other words, the slider 2 can slide vertically on the bending machine body 1, and the specific sliding structure will not be described in detail here. The slider 2 drives the upper die 7 and the lower die 8 fixed on the workbench 3 to cooperate in bending the workpiece 9, and the connecting plate 4 can slide horizontally on the slider 2, driving the baffle 6 to push the workpiece 9 out of the bending machine from one side of the workpiece 9 in the horizontal direction. The baffle 6 is located above the workbench 3. Because the workpiece 9 needs to be placed above the workbench 3, when the connecting plate 4 drives the baffle 6 to slide horizontally on the slider 2 and push the workpiece 9, the baffle 6 needs to be located on one side of the end of the workpiece 9. At this time, the height of the baffle 6 needs to be higher than the workbench 3, but not higher than the highest point of the end of the workpiece 9, so that the workpiece 9 can be pushed from one end of the bending machine to the other end for side discharge.

[0033] like Figure 2As shown, the slider 2 has a linear guide 10, and the connecting plate 4 has a slide groove 11 corresponding to the linear guide 10. The connecting plate 4 slides on the slider 2 through the cooperation of the linear guide 10 and the slide groove 11, and drives the baffle 6 connected to the connecting plate 4 to push the workpiece 9 to be discharged from the side of the bending machine in the horizontal direction. A rack 12 is also fixed on the slider 2, and the power device 5 includes a motor 14, a reducer 13 and a rotating shaft 15. The motor 14 is installed on the reducer 13, and the reducer 13 is fixed on the connecting plate 4. One end of the rotating shaft 15 is connected to the reducer 13, and the other end of the rotating shaft 15 is connected to a gear 16 that cooperates with the rack 12. The motor 14 drives the reducer 13 and drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the gear 16 to rotate. The reducer 13 is fixed on the connecting plate 4, so the connecting plate 4 can be driven to slide through the coordinated rotation of the gear 16 and the rack 12, thereby driving the connecting plate 4 to slide horizontally on the slide.

[0034] like Figure 1 and Figure 4 As shown, the discharging mechanism also includes a conveying device 17 for conveying the workpiece 9, the conveying device 17 includes a plurality of conveying units 18, the conveying unit 18 includes a roller 19, the rollers 19 in two oppositely arranged conveying units 18 are tilted and assembled into a "V-shaped" structure 20, and a plurality of the "V-shaped" structures 20 are assembled into a "V-shaped" channel, and the workpiece 9 is conveyed in the "V-shaped" channel. Two adjacent conveying units 18 are placed horizontally, and the two corresponding rollers 19 are tilted inward, and the outer ends are tilted upward to form a shape such as a "V-shaped" structure 20, and then the rollers 19 of two conveying units 18 are assembled into a shape such as a "V-shaped" structure 20 at intervals, so that the plurality of the "V-shaped" structures 20 are assembled into a "V-shaped" channel, and the workpiece 9, such as a steel pipe, can be conveyed and transported in the "V-shaped" channel.

[0035] like Figure 4 and Figure 5 As shown, the conveying unit 18 further includes a support rod 21 and a bracket 22, one end of the support rod 21 is hinged to the bracket 22, and the other end of the support rod 21 is hinged to the roller 19. The bracket 22 is responsible for supporting the entire conveying device 17 and can be fixed by bolts. The structure of the support rod 21 being hinged can facilitate the tilting setting of the roller 19, and further, the tilting angle can be adjusted according to the size of the workpiece 9, that is, the size of the "V-shaped" channel can be adjusted.

[0036] Preferably, the support rod 21 is hinged on one end of the roller 19, and the other end of the roller 19 is hinged to the bracket 22, that is, both ends of the roller 19 are connected in a hinged manner. Compared with the support of only the support rod 21, both ends have hinged support force, which will be more stable. When conveying the workpiece 9, the "V-shaped" channel formed has stronger support force.

[0037] like Figure 6 As shown, the conveying unit 18 also includes a roller seat 23, a connecting shaft 24 is fixed on the roller seat 23, and the roller 19 is rotatably mounted on the connecting shaft 24; the roller seat 23 is also provided with a connecting ear 25, and the roller 19 and the support rod 21 and the bracket 22 are all hingedly connected through the connecting ear 25. Since the roller 19 needs to rotate to better convey the workpiece 9, the roller 19 is fixed on the connecting shaft 24 for rotation, and the connecting shaft 24 can be fixed on the roller seat 23; the connection ear 25 is also convenient for hinge connection, and specifically, a perforation can be set on the connection ear 25 to facilitate the connection of the hinge device.

[0038] Working principle: The slider 2 in this scheme can slide vertically on the bending machine body 1, driving the upper die 7 and the lower die 8 to close the die to bend the workpiece 9, and then the motor 13 drives the reducer 14 to drive the rotating shaft 15 to rotate, and with the cooperation of the gear 16 and the rack 12, drive the connecting plate 4 to slide horizontally on the slider 2, and the connecting plate 4 drives the baffle 6 located on one end of the workpiece 9 to move and push the workpiece 9 to the side of the bending machine for discharge, replacing the problem of steel plate clamps occupying space in the prior art. Then the workpiece 9 enters the conveying device 17 from the side of the bending machine, and the "V-shaped" channel formed by the rotating roller 19 conveys the workpiece 9 to the next working link.
