Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a bending machine clamp which is easy to fix. Background Art

[0002] The bending machine mainly achieves the purpose of bending by applying pressure to make materials such as metal sheets undergo plastic deformation. Its core components are the upper and lower molds. The upper mold (also called the bending knife) is usually a convex mold with a certain shape, and the lower mold is a concave mold that matches the upper mold. When the material is placed between the upper and lower molds, the upper mold is driven downward by a hydraulic system, a mechanical transmission system, or a servo motor system to bend the material according to the shape of the lower mold. In this process, a clamp is needed to clamp and fix the material to prevent the material from shaking randomly during bending.

An adapter plate 343 is provided at the end of the telescopic rod 341. A limit block 344 is provided on the outer wall of the adapter plate 343. The outer wall of the limit block 344 is inserted into the limit plate 331, and a spring 342 is provided between the adapter plate 343 and the support block 32.

[0029] It should be noted that: by providing a rotating support block 32 in the support assembly 3, the support block 32 can be controlled to rotate as needed during use, that is, when the plate material needs to be bent, the plane of the support block 32 is made to support the plate upward, and when the pipe material needs to be bent, the side of the support block 32 with the slot 322 can be made to support the pipe. Therefore, the device can support and fix both the plate and the pipe, thereby improving the scope of application of the device;

[0030] Through the clamping connection between the limit block 344 and the limit plate 331, after the flipping adjustment of the support block 32 is completed, when the linkage plate is released, the spring 342 can drive the linkage plate and the limit block 344 on the outer wall thereof to move toward the limit plate 331 through its own force, so that the limit block 344 is clamped into the limit plate 331, so that the support block 32 can be stably supported by the mutual resistance of the limit block 344 and the limit plate 331.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 5 A positioning assembly 5 is provided on the two slides 2, and the positioning assembly 5 includes positioning pieces 51. The positioning pieces 51 are provided in two groups and are symmetrically distributed outside the two slides 2, and each group of positioning pieces 51 has two pieces. Racks 511 are provided on the opposite surfaces of the same group of positioning pieces 51, and the racks 511 are staggered up and down. Gears 512 that are meshed and connected are provided between the racks 511, and the gears 512 are rotatably connected to the side walls of the slides 2. A sliding groove 22 is provided on the side walls of the slides 2, and a sliding bar 52 that is slidably connected is inserted into the inner wall of the sliding groove 22, and the outer wall of the sliding bar 52 is fixedly connected to the outer wall of the rack 511. A linkage bar 53 is arranged between the two groups of positioning pieces 51, and the linkage bars 53 on both sides are staggered and slidably connected.

[0032] It should be noted that: through the setting of the rack 511 and the gear 512, when the positioning piece 51 on one side is turned, the meshing of the rack 511 and the gear 512 can drive the corresponding positioning pieces 51 in the same group to move synchronously, and through the setting of the linkage bar 53, when the positioning piece 51 in any group is turned, the moved positioning piece 51 can drive the positioning pieces 51 in the other group to move synchronously through the linkage bar 53, so that when used later, the staff can randomly turn any positioning piece 51 to make the two groups of positioning pieces 51 move synchronously, and through the squeezing of the positioning pieces 51 on both sides, the center of the plate and the center of the mounting plate 1 can be made to be in the same plane, so that the plate can be quickly positioned, thereby improving the accuracy of the plate bending in the later stage.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 5 Cylinders 12 are provided on both sides of the top of the mounting plate 1, and the ends of the cylinders 12 are fixedly connected to the side walls of the slide seat 2. A guide groove 11 is provided at the relative position of the mounting plate 1 and the slide seat 2, and the inner wall of the guide groove 11 is abutted against and slidably connected to the bottom of the slide seat 2.

[0034] It should be noted that: through the setting of the cylinder 12, when in use, the slide 2 can be flexibly driven to move, and then the gap between the support components 3 on the slides 2 on both sides can be adjusted, so that the support components 3 can support materials of different lengths.

[0035] In the embodiments of the present invention, please refer to Figures 1 to 5 A mounting groove 21 is provided inside the slide 2, and the inner wall of the mounting groove 21 abuts against and is slidably connected to the outer wall of the insert block 31. A connecting hole 23 is provided inside the slide 2, and a docking hole 311 is provided inside the insert block 31 at a position opposite to the connecting hole 23, and a threaded connecting pin 24 is provided between the connecting hole 23 and the docking hole 311.

[0036] It should be noted that: by using the connecting pin 24 to limit the plug block 31, when the support assembly 3 needs to be repaired or replaced during later use, the connecting pin 24 can be directly removed from the docking hole 311 in the plug block 31 to release the limit on the plug block 31, so that the plug block 31 can be directly removed from the slide seat 2, thereby making it more convenient for the staff to replace the support assembly 3 later.

[0037] In the embodiments of the present invention, please refer to Figures 1 to 5 A fixed support frame 4 is provided on the plug block 31, a rotatably connected screw rod 41 is provided inside the support frame 4, a threaded adapter plate 42 is provided outside the screw rod 41, the inner wall of the adapter plate 42 is slidably connected to the outer wall of the support rod in the support frame 4, an extrusion sheet 43 is provided at the bottom of the adapter plate 42, and extrusion strips 44 are provided on both sides of the extrusion sheet 43 at the bottom of the adapter plate 42, and the position of the extrusion sheet 43 is opposite to the position of the card slot 322.

[0038] It should be noted that: since the position of the extrusion sheet 43 is opposite to the position of the slot 322, and the extrusion strips 44 are located on both sides of the extrusion sheet 43, when the tubular material is bent, the extrusion strips 44 located on both sides can move downward from the outside of the two side walls of the tube, and then the bottom of the extrusion sheet 43 above the slot 322 can be accurately moved downward to the inside of the slot 322 and abut against the outer wall of the tube, thereby stably clamping and fixing the tube.

[0039] The working principle of the bending machine clamp that is easy to fix provided by the utility model is as follows;

[0040] When using the device, the device can be installed on the bending machine first, and then the adapter plate 343 can be held as needed, and pressed in the direction close to the support block 32. At this time, the adapter plate 343 can squeeze the telescopic rod 341, so that the limit blocks 344 on the outer wall and side wall of the adapter plate 343 are separated from the limit plate 331, and the limit on the limit plate 331 is released. At this time, the limit plate 331 can be held so that it drives the support block 32 to rotate through the rotating rod, and the position of the card slot 322 on the outer wall of the support block 32 is adjusted;

[0041] When the material to be bent is a pipe, the pipe can be placed in the slot 322 first, so that the outer wall of the pipe is against the inner wall of the slot 322, and then the cylinder 12 can be controlled to drive the slide 2 and the support block 32 on the outer wall to move. When the outer wall of the baffle 324 in the support block 32 is against the outer wall of the pipe, the controller of the external terminal can obtain the extrusion force between the baffle 324 and the pipe through the pressure sensor 323 outside the baffle 324. When the values ​​of the pressure sensors 323 on both sides are the same as the set values, the cylinder 12 can be stopped from working.

[0042] Then, the screw rod 41 can be controlled to rotate, so that the screw rod 41 drives the adapter plate 42 to slide on the support frame 4, until the end of the extrusion sheet 43 under the adapter plate 42 abuts against the outer wall of the pipe, so that the pipe material can be clamped and fixed, so that the bending machine can stably bend the pipe;

[0043] When the material to be bent is a plate, the planar structure of the support block 32 can be adjusted to the upward direction first, and then the plate can be placed on the support block 32. After the plate is placed, the staff can move the positioning piece 51 in the positioning assembly 5 to move the positioning piece 51 toward the direction of the support block 32. The moving positioning piece 51 can drive the rack 511 on the outer wall to move synchronously, and the engagement between the rack 511 and the gear 512 can drive the positioning piece 51 on the other side to move synchronously through the rack 511 on the other side of the gear 512. At the same time, in this process, the moving positioning piece 51 can also drive the positioning piece 51 in the other group to move synchronously through the linkage bar 53. When the outer walls of the two groups of positioning pieces 51 are against the side walls of the plate, the center line of the plate and the center line of the mounting plate 1 can be placed on the same plane.

[0044] At this time, the cylinder 12 drives the slide 2 and the support block 32 to move, so that the inner baffle 324 of the support block 32 abuts against the side wall of the plate, thereby achieving precise positioning of the plate. Then the screw rod 41 can be controlled to rotate, so that the extrusion strip 44 under the adapter plate 42 abuts against the top of the plate, and the plate can be fixed, thereby facilitating the bending machine to bend the plate.

[0045] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0046] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
