Description

Technical Field

[0001] This utility model relates to a workpiece bending device, specifically a rapid bending device for hardware processing. Background Technology

[0002] A hardware bending device is a piece of equipment used to bend hardware parts (such as metal sheets) into a specific shape. During processing, one end of the hardware part is placed in the bottom die, and then the upper die (punch) is fixed on the bending machine. The bending machine is started, bringing the upper die close to the hardware part and pressing down on its surface, causing it to bend.

[0003] Most existing hardware bending devices only have one bottom mold. When the bottom mold does not meet the processing requirements, the old bottom mold needs to be disassembled and then replaced with a new bottom mold. The replacement process takes a long time, which is not conducive to improving the bending efficiency of hardware. Utility Model Content

[0004] The purpose of this utility model is to provide a quick bending device for hardware processing, which can quickly complete the switching of the bottom mold without removing the existing bottom mold, eliminating the step of disassembling the old bottom mold and replacing it with a new bottom mold, thereby improving the bending efficiency of hardware.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid bending device for hardware processing, comprising a support mechanism, a fixing mechanism and a bending mechanism disposed on the support mechanism. The support mechanism includes a processing table and a base plate fixed to the upper surface of the processing table. A servo motor is fixed on the base plate, and a lead screw and a guide rod are disposed in the cavity of the base plate. The lead screw is fixedly connected to the output end of the servo motor. The fixing mechanism includes a fixing seat, on which multiple fixing cylinders are fixed. The output ends of the multiple fixing cylinders are all fixedly connected to sliding plates. A bottom mold is fixed on the upper surface of the multiple sliding plates. Magnets are fixed at both ends of each sliding plate, and springs and inner sliders connected to the springs are disposed at both ends of each sliding plate. Each spring is fixedly connected to the fixing seat. An iron block and a lower platform are fixed on each inner slider. The iron block is in contact with the magnet. When the iron block is magnetically attracted and fixed to the magnet, the iron block will pull the inner slider closer to the sliding plate, causing the lower platform to move under the sliding plate and support the sliding plate.

[0006] Preferably, there are two guide rods, which are symmetrical about the two ends of the lead screw. Both guide rods are fixed in the cavity of the base plate. The fixing seat is installed on the lead screw, and the two ends of the fixing seat are respectively set on the two guide rods.

[0007] Preferably, multiple mounting chambers are provided in the fixed base, and multiple fixed cylinders are fixed in the multiple mounting chambers respectively, and the multiple fixed bases are all vertically arranged.

[0008] Preferably, each installation chamber is provided with two symmetrically distributed receiving slots, and the springs at both ends of each slide plate are respectively set in the two receiving slots, with the inner slider connected to the spring fitting against the inner wall of the receiving slot.

[0009] Preferably, multiple fixing grooves are provided on the upper end face of the fixing base, and multiple bottom molds are slidably disposed in the multiple fixing grooves along the vertical direction.

[0010] Preferably, all the bottom molds have bending grooves and are distributed at equal intervals.

[0011] Preferably, the bending mechanism includes a support frame and a bending cylinder fixed to the upper end face of the support frame. The support frame is fixed to the upper end face of the support mechanism, and a top plate is fixedly connected to the output end of the bending cylinder.

[0012] Preferably, the bending cylinder and the top plate are located at both ends of the support frame, and the bottom of the top plate is detachably equipped with a top mold, which has a mold head.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes multiple bottom molds mounted on a fixed base, each with a different bending groove, to accommodate the bending of various hardware parts. When switching between different bottom molds, a servo motor drives a lead screw to rotate, moving the desired bottom mold below the top mold, thus changing the shape of the bent hardware part to meet different processing requirements. The multiple bottom molds allow for rapid mold switching without disassembling existing molds, eliminating the need to remove old molds and replace them with new ones, thereby improving bending efficiency and enabling rapid bending of hardware parts.

[0024] Please see Figure 1One embodiment of this utility model is a rapid bending device for processing hardware parts, comprising a support mechanism 1, a fixing mechanism 2 disposed on the support mechanism 1, and a bending mechanism 3.

[0025] Please see Figure 2 The support mechanism 1 includes a processing table 11 and a base plate 12 fixed to the upper surface of the processing table 11. A servo motor 13 is fixed on the base plate 12, and a lead screw 14 and two guide rods 15 are provided in the cavity of the base plate 12. The lead screw 14 is fixedly connected to the output end of the servo motor 13. The two guide rods 15 are symmetrical about the two ends of the lead screw 14. Both guide rods 15 are fixed in the cavity of the base plate 12. The fixing mechanism 2 includes a fixing seat 21.

[0026] Please see Figure 3 The fixed seat 21 is mounted on the lead screw 14, and the two ends of the fixed seat 21 are respectively set on two guide rods 15, so that when the lead screw 14 is running, it can drive the fixed seat 21 to move horizontally with the guide rods 15. Multiple installation chambers 211 and multiple fixing grooves 212 are provided in the fixed seat 21. Multiple fixing cylinders 22 are fixed on the fixed seat 21. The multiple fixing cylinders 22 are respectively fixed in the multiple installation chambers 211, and the multiple fixed seats 21 are all vertically set. The output ends of the multiple fixing cylinders 22 are all fixedly connected to the slide plate 23. The bottom mold 24 is fixed on the upper surface of the multiple slide plates 23. The multiple bottom molds 24 are slidably set in the multiple fixing grooves 212 in the vertical direction. The multiple bottom molds 24 have bending grooves 241, and the multiple bottom molds 24 are evenly distributed.

[0027] Please see Figure 4 Each installation chamber 211 contains two symmetrically distributed receiving slots 213. Magnets 25 are fixed to both ends of each slide plate 23, and springs 26 and inner sliders 27 connected to the springs 26 are also provided at both ends of each slide plate 23. Each spring 26 is fixedly connected to a fixed base 21. An iron block 28 and a lower platform 29 are fixed to each inner slider 27. The springs 26 at both ends of each slide plate 23 are respectively located within the two receiving slots 213. The inner sliders 27 connected to the springs 26 are in contact with the inner wall of the receiving slot 213, and the inner sliders 27 are always located within the receiving slot 213. The inner slider 27 can only move horizontally without wobbling or falling. Therefore, the inner slider 27 and the lower platform 29 can be used to support the slide plate 23, so that the slide plate 23 supports the bottom mold 24. Even if the bottom mold 24 is subjected to pressure from above, it can remain stable. In use, when the magnet 25 moves to the designated position, the iron block 28 can contact and connect with the magnet 25. When the iron block 28 is magnetically attracted and fixed to the magnet 25, the iron block 28 will pull the inner slider 27 closer to the slide plate 23, so that the lower platform 29 moves under the slide plate 23 and supports the slide plate 23.

[0028] Please see Figure 5The bending mechanism 3 includes a support frame 31 and a bending cylinder 32 fixed to the upper end face of the support frame 31. The support frame 31 is fixed to the upper end face of the support mechanism 1. The output end of the bending cylinder 32 is fixedly connected to a top plate 33. The bending cylinder 32 and the top plate 33 are located at both ends of the support frame 31, respectively. A top mold 34 is detachably installed at the bottom of the top plate 33. The top mold 34 has a mold head 341, which is located above multiple bending grooves 241. The installation method between the top plate 33 and the top mold 34 is the prior art, such as fixing with bolts, so that the top mold 34 is a detachable design.

[0029] Please refer to the following: Figures 1 to 5 In the operation of this utility model, according to the actual needs of processing hardware parts, a designated bottom mold 24 is selected and moved to directly below the top mold 34. The bottom mold 24 is moved as follows: the servo motor 13 drives the lead screw 14 to rotate, causing the fixed base 21 to move horizontally with the two guide rods 15. Thus, the bottom mold 24 to be used can be moved to directly below the top mold 34. Then, the fixed cylinder 22 below the bottom mold 24 is operated, driving the slide plate 23 and the bottom mold 24 to rise, so that the bottom mold 24 gradually rises from the fixed groove 212, and the bottom mold 24... 4. Higher than other bottom molds 24, as the magnets 25 at both ends of the slide plate 23 rise, the two iron blocks 28 gradually approach the two magnets 25 and are magnetically attracted and fixed to them. At the same time, the two inner sliders 27 are pulled closer to the slide plate 23, so that the two lower platform plates 29 can just move to the bottom of the slide plate 23 and support the slide plate 23. Then the hardware to be processed is placed on the bottom mold 24. Subsequently, the bending cylinder 32 runs and drives the top plate 33 and the top mold 34 to sink, so that the top mold 34 presses the hardware into the bending groove 241, thus completing the bending work.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
