Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to a bending machine mold clamping device. Background Technology

[0002] Bending machines are important equipment in the sheet metal industry for bending and forming workpieces. Their function is to press steel plates into parts of various shapes according to process requirements. Their main working principle is that the hydraulic system provides power and the electrical system gives instructions. Under the action of the oil cylinder, the slide block drives the upper die downward to close with the lower die to achieve the bending of the sheet material. During the use of bending machines, it is often necessary to replace different upper dies by disassembling and assembling the clamping device according to different workpieces.

[0003] Most existing clamping devices do not have a clamping detection structure. During the disassembly and assembly process, improper operation by the staff may result in the clamp not being clamped properly. Subsequently, the clamp may become loose due to loose or damaged parts. If the staff cannot detect and deal with the problem in time, it can easily lead to the escalation of the fault and cause unnecessary losses. Utility Model Content

[0004] The purpose of this utility model is to solve the following problems existing in the prior art: most existing clamping devices do not have a clamping detection structure. During the disassembly and assembly process, improper operation by the staff may result in failure to clamp properly. Subsequently, the clamping may also become loose due to loose or damaged parts. If the staff cannot detect and handle the problem in time, it can easily lead to the escalation of the fault and cause unnecessary losses.

[0005] To address the problems existing in the prior art, this utility model provides a bending machine mold clamping device, including a bending machine body and a clamping body. Two sets of clamps are provided below the clamping body. Each clamp has a handle and a motor on one side. Pressure sensors are provided inside each clamp. Grooves are provided in the clamps below the pressure sensors, and pressure compensation structures are provided in the grooves.

[0006] Furthermore, the pressure compensation structure includes a rotating rod and a locking block. One end of the rotating rod is connected to the output end of the motor. A gear is provided around the rotating rod, and a movable toothed plate meshes with the gear below. The locking block is connected to the movable toothed plate.

[0007] Furthermore, the movable toothed plate is movably mounted in the groove via a guide rail, and the side of the movable toothed plate near the opening of the groove is fixedly connected to the locking block.

[0008] Furthermore, the card block is also provided with a concave card groove, which can be engaged with the protruding part of the upper mold during use.

[0009] Furthermore, the control components of the motor are electrically connected to the pressure sensor.

[0010] Furthermore, the fixture body is also equipped with an electronic display screen and indicator lights, both of which are electrically connected to the pressure sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During use, when the pressure sensor detects an abnormal clamping degree, the indicator light on the electronic display flashes a red fault light, reminding the staff to check and repair it. After receiving the signal, the motor controls the rotating rod to rotate, which in turn drives the gear to rotate. The gear then drives the movable toothed plate to move, which in turn causes the locking block to extend out of the groove. The extended locking block abuts against and locks the mold, increasing the clamping degree and preventing the upper mold from loosening or falling off. This avoids escalating the fault and causing unnecessary losses, thus increasing the practicality of the device. Attached Figure Description

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] Example 1

[0020] like Figure 1-3As shown, a bending machine mold clamping device includes a bending machine body 1 and a clamping body 2. Two sets of clamps 6 are provided below the clamping body 2. A handle 4 is provided on the clamp 6. A motor 5 is provided on one side of the clamp 6. A pressure sensor 7 is provided on the inner side of each clamp 6. A groove 8 is provided in the clamp 6 below the pressure sensor 7. A pressure compensation structure is provided in the groove 8.

[0021] In this embodiment, the pressure compensation structure includes a rotating rod 10 and a locking block 9. One end of the rotating rod 10 is connected to the output end of the motor 5. A gear 11 is provided on the periphery of the rotating rod 10. A movable toothed plate 12 meshes with the lower part of the gear 11. The locking block 9 is connected to the movable toothed plate 12. The movable toothed plate 12 is movably set in the groove 8 through a guide rail. The side of the movable toothed plate 12 near the opening of the groove 8 is fixedly connected to the locking block 9. The locking block 9 is also provided with a concave locking groove. In use, the concave locking groove can engage with the protruding part of the upper mold. The control component of the motor 5 is electrically connected to the pressure sensor 7. The fixture body 2 is also provided with an electronic display screen 3 and an indicator light. The electronic display screen 3 and the indicator light are both electrically connected to the pressure sensor 7.

[0022] Working principle description: After the clamp body 2 is fixedly connected to the bending machine body 1, the operator places the upper mold between the chucks 6. By rotating the tightening handle 4, the chucks 6 clamp the upper mold, thus achieving the clamping effect. After clamping, the clamping degree is detected by the pressure sensor 7 inside the chucks 6 and displayed on the electronic display screen 3 for easy viewing by the operator. During use, when the pressure sensor 7 detects an abnormal clamping degree, the indicator light on the electronic display screen 3 flashes a red fault light to remind the operator to check and repair. After receiving the signal, the motor 5 controls the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the gear 11 to rotate, and the rotation of the gear 11 drives the movable toothed plate 12 to move. The movement of the movable toothed plate 12 causes the locking block 9 to extend from the groove 8. The extended locking block 9 abuts against and locks the upper mold, increasing the clamping degree and preventing the upper mold from loosening and falling off, thus avoiding unnecessary losses caused by escalating faults and increasing the practicality of this device.
