[0002] IGBT is an insulated gate bipolar transistor, which combines the advantages of power transistors and power field effect transistors, has good characteristics, and has a wide range of application fields. IGBT is also a three-terminal device, including a gate, a collector, and an emitter.

[0003] At present, most of the IGBT benders are large-scale automated machines. For R & D and small-batch production, the equipment is large and expensive, and there is no such small-scale equipment for bending IGBTs on the market.

[0004] Therefore, it is necessary to propose a manual IGBT bender to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a manual IGBT bender, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A manual IGBT bender includes a platform. A folding plate is installed on the right side of the platform. A rear limiting plate is movably connected to the left side of the top of the platform. An upper pressing rod is installed on the right side of the top of the platform. A side limiting block is arranged on the back of the upper pressing rod. A clamp assembly is arranged on the top of the platform.

[0008] Preferably, hinges are symmetrically installed on the front and back of the right side of the platform. The right sides of the two hinges are symmetrically installed on the front and back of the left side of the folding plate. A folding plate rod is fixedly connected to the right side of the folding plate.

[0009] Preferably, a first positioning hole is opened on the right side of the top of the platform. Installation grooves are symmetrically opened on the front and back of the top of the platform. Use grooves are symmetrically opened on the front and back of the top of the rear limiting plate. The size of the use groove is adapted to the first positioning hole.

[0010] Preferably, platform side plates are symmetrically arranged on the front and back of the top of the platform. The top of the platform side plate is threadedly connected with a platform upper plate. The platform side plate is installed on the top of the platform through the platform upper plate and the installation groove.

[0011] Preferably, a lower pressing rod is installed on the right side of the top of the platform. A second positioning hole is opened on the back of the right side of the top of the platform. The side limiting block is installed on the right side of the platform through the second positioning hole. The side limiting block is arranged on the left side of the lower pressing rod.

[0012] Preferably, the clamp assembly is threadedly connected to the center of the top of the platform upper plate. A limit seat is rotatably connected to the outer wall of the clamp assembly. A handle is fixedly connected to the center of the top of the limit seat. A connecting arm is installed in the inner cavity of the clamp assembly through a torsion rotating shaft. A threaded rod is threadedly connected in the inner cavity on the right side of the connecting arm. A positioning nut is threadedly connected to the top of the threaded rod. The bottom of the positioning nut is attached to the top of the connecting arm. A upper pressing rod is installed at the bottom of the threaded rod.

[0013] Beneficial effects

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. This IGBT manual bender is small in size. The IGBT can be bent manually, and the overall cost is relatively low. This bender can bend up to six IGBTs at a time, and the efficiency can be guaranteed. The rear limit plate and the side limit blocks installed movably can fix the IGBT according to its size and quantity, so as to facilitate the bending work of the IGBT. At the same time, through the threadedly connected lower pressing rod, the brass sheet can be used for heightening treatment, so as to adapt to IGBTs of different heights for loading.

[0016] 2. This IGBT manual bender is convenient for the rear limit plate to move on the top of the platform through the opened use groove and the first positioning hole, so as to adapt to the size of the IGBT for limiting treatment. Through the opened second positioning hole and the set side limit blocks, the IGBT can be limited according to its size.

[0017] 3. This IGBT manual bender, through the set clamp assembly, operating the handle can drive the limit seat to press down the connecting arm, so that the connecting arm can drive the upper pressing rod to press down through the threaded rod, and cooperate with the set lower pressing rod to fix the IGBT. By moving the set folding plate rod, the folding plate can be driven to fold up, and at this time the IGBT can be bent. Description of the drawings

[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0023] As Figures 1 - 3 shown, a manual IGBT bender includes a platform 1. A folding plate 3 is installed on the right side of the platform 1. A rear limit plate 15 is movably connected to the left side of the top of the platform 1. An upper pressure rod 14 is installed on the right side of the top of the platform 1. A side limit block 19 is arranged on the back of the upper pressure rod 14. A clamp assembly 7 is arranged on the top of the platform 1. Hinges 2 are symmetrically installed on the front and back of the right side of the platform 1. The right sides of the two hinges 2 are symmetrically installed on the front and back of the left side of the folding plate 3. A folding plate rod 4 is fixedly connected to the right side of the folding plate 3. A first positioning hole 17 is opened on the right side of the top of the platform 1. Installation grooves 18 are symmetrically opened on the front and back of the top of the platform 1. Use grooves 16 are symmetrically opened on the front and back of the top of the rear limit plate 15. The size of the use groove 16 is adapted to the first positioning hole 17. Side plates 6 of the platform are symmetrically arranged on the front and back of the top of the platform 1. The top of the side plate 6 of the platform is threadedly connected with an upper plate 5 of the platform. The side plate 6 of the platform is installed on the top of the platform 1 through the upper plate 5 of the platform and the installation groove 18. A lower pressure rod 20 is installed on the right side of the top of the platform 1. A second positioning hole 21 is opened on the back of the right side of the top of the platform 1. The side limit block 19 is installed on the right side of the platform 1 through the second positioning hole 21. The side limit block 19 is arranged on the left side of the lower pressure rod 20. The clamp assembly 7 is threadedly connected to the center of the top of the upper plate 5 of the platform. A limit seat 10 is rotatably connected to the outer wall of the clamp assembly 7. A handle 11 is fixedly connected to the center of the top of the limit seat 10. A connecting arm 9 is installed in the inner cavity of the clamp assembly 7 through a torsion rotating shaft. A threaded rod 13 is threadedly connected in the inner cavity on the right side of the connecting arm 9. A positioning nut 12 is threadedly connected to the top of the threaded rod 13. The bottom of the positioning nut 12 abuts against the top of the connecting arm 9. The bottom of the threaded rod 13 is installed with an upper pressure rod 14.

[0024] Small in size, it can bend IGBTs manually, with relatively low overall cost. This bender can bend up to six IGBTs at a time, ensuring efficiency. The rear limit plate 15 and side limit blocks 19 installed movably can fix IGBTs according to their size and quantity, thus facilitating the bending work of IGBTs. At the same time, the pressing rod 20 connected by threads can be padded with brass sheets to adapt to IGBTs of different heights for loading. Through the use slots 16 and the first positioning holes 17 opened, it is convenient for the rear limit plate 15 to move on the top of the platform 1, so as to limit IGBTs according to their size. Through the second positioning holes 21 opened and the side limit blocks 19 set, IGBTs can be limited according to their size. By setting the clamp assembly 7 and operating the handle 11, the limit seat 10 can be driven to press down the connecting arm 9, so that the connecting arm 9 can drive the upper pressing rod 14 to press down through the threaded rod 13. Cooperating with the set pressing rod 20, the IGBTs can be fixed. By moving the folding plate rod 4 set, the folding plate 3 can be driven to fold up, and at this time the IGBTs can be bent.

[0025] It should be noted that the present utility model is a manual bender for IGBTs. When in use, the IGBTs are placed on the top of the platform 1, and the rear limit plate 15 and the side limit blocks 19 are adjusted according to their size. After the rear limit plate 15 and the side limit blocks 19 are adjusted, the side limit blocks 19 are positioned through the first positioning holes 17 and the second positioning holes 21. At this time, the fixation of the IGBTs is completed. If multiple IGBTs are installed at one time, the height of the pressing rod 20 is adjusted according to their thickness, and brass sheets can be padded at its bottom. Rotate the handle 11 so that the limit seat 10 can drive the connecting arm 9 to press down, so that the threaded rod 13 can drive the upper pressing rod 14 to press on the top of the IGBTs. Cooperating with the pressing rod 20, the bottom of the IGBTs can be fixed. Flip the folding plate rod 4 upwards, and at this time the IGBTs can be bent.
