[0007] As a further solution of the present invention, the driving group includes two support rods, a U-shaped rod and a first spring. The two support rods are respectively rotatably connected to the front and rear sides of the formed part. The bottom ends of the two support rods are slidably connected with slide grooves. The two slide grooves are both opened on the support plate. The inner sides of the U-shaped rods are opened with inclined surfaces and the two inclined surfaces are respectively in contact with the two support rods. The U-shaped rod is fixedly connected to the end of the frame plate, the baffle is slidably connected to the support plate, and the first spring is fixedly connected between the baffle and the inner wall of the support plate.

[0008] As a further solution of the present invention, an extension plate is arranged in front of the transverse plate, and the rear end of the extension plate is U-shaped and extends to the bottom end of the transverse plate and is fixedly connected to the transverse plate.

[0009] As a further solution of the present invention, a limiting plate is arranged outside the extension plate, the extension plate is located directly in front of the blocking member, and the limiting plate is fixedly connected to the side wall of the blocking member.

More importantly, the T-shaped steel piece can be fixed from the back of the cutting disk, so that when the cutting disk is cutting, the thin T-shaped steel piece will not bend or deform to affect the accuracy and efficiency of cutting.

[0031] See also Figure 1-Figure 12 The present invention provides a technical solution: a T-shaped steel punching device with sawing function, comprising a machine body 1, two sets of punching heads 2 located at the front and rear of the machine body 1, and a cutting disc 3, a support plate 4 arranged obliquely is fixedly connected to the machine body 1, a stopper 5 is arranged on the support plate 4, the stopper 5 is U-shaped, a frame plate 6 is slidably connected to the support plate 4, a cylinder 7 is fixedly connected between the frame plate 6 and the support plate 4, and forming groups are respectively arranged on the front and rear sides of the frame plate 6, and the two forming groups are respectively located on one side of the two punching heads 2;

[0032] The forming group includes a motor 8 fixedly connected to the frame plate 6 and a forming member 13 arranged on the right side of the stopper 5, the forming member 13 is fixedly connected to the top end of the stopper 5, and the side wall of the forming member 13 is flush with the side wall of the stopper 5, the output shaft of the motor 8 is fixedly connected to the driving disk 9, and the driving disk 9 is fixedly connected to the shift block 10, the shift block 10 is eccentrically arranged with the driving disk 9, and the outside of the shift block 10 is slidably connected to a swing rod 11, the swing rod 11 is rotatably connected to the support plate 4, the top end of the swing rod 11 is rotatably connected to the push rod 12, the push rod 12 is rotatably connected to the guide rod 22, the guide rod 22 is slidably connected to the support plate 4, the bottom end of the guide rod 22 is fixedly connected to the punch head 2, the cutting disk 3 is rotatably connected to the side wall of the guide rod 22, and a through hole for the punch head 2 to pass through is opened on the forming member 13.

[0033] like Figure 1-Figure 7 As shown:

[0034] The T-shaped steel piece 29 is passed forward from the rear of the right stopper 5 until the front end of the T-shaped steel piece 29 is behind the cutting disc 3, and the vertical side wall of the T-shaped steel piece 29 is in contact with the side wall of the stopper 5 (such as Figure 5As shown), since the support plate 4 is inclined, the T-shaped steel piece 29 can be easily fitted after being placed, and a conveying group for conveying the T-shaped steel piece 29 forward is provided at the rear of the machine body 1 in actual use (it can also be pushed manually), and then the punching work can be carried out;

[0035] Punching work:

[0036] When punching for the first time, start the motor 8, the motor 8 rotates to drive the shift block 10 to rotate, and when the shift block 10 rotates, it will slide inside the swing rod 11 and drive the top end of the swing rod 11 to swing. When the swing rod 11 swings, it will drive the push rod 12 to push the guide rod 22 to slide along the support plate 4. At this time, the guide rod 22 will drive the punching head 2 and the cutting disc 3 to move in the direction close to the T-shaped steel part 29. After the punching head 2 contacts the T-shaped steel part 29, the T-shaped steel part 29 will be punched, and the forming part 13 is fixedly connected to the top end of the stopper 5, which can provide support for the T-shaped steel part 29 from the side wall. When the punching head 2 completes the punching of the T-shaped steel part 29, it will pass through the T-shaped steel part 29 and enter the through hole on the forming part 13, thereby completing the punching operation of the T-shaped steel part 29, and the cutting The cutting disc 3 is located in front of the T-shaped steel piece 29, and will not cut the T-shaped steel piece 29 during the first punching. The shifting block 10, the driving disc 9, the swinging rod 11, the push rod 12 and the guide rod 22 are crank slider mechanisms, so the guide rod 22 has a quick return characteristic when returning, that is, the return speed of the guide rod 22 after the punching is completed is greater than the stroke during the punching, so it can be quickly reset after the punching is completed, and then the conveying group can convey the T-shaped steel piece 29 from the rear, so that the T-shaped steel piece 29 is moved forward a fixed distance in contact with the side wall of the stopper 5 and the forming piece 13, which can improve the overall efficiency when punching multiple sections of the T-shaped steel piece 29, and can reduce the load during the punching operation, and no clamping is required, and the stopper 5 and the forming piece 13 can be used for support;

[0037] When punching T-shaped steel pieces 29 of different sizes, the thickness of the T-shaped steel piece 29 will increase. At this time, it is only necessary to start the cylinder 7 to extend the cylinder 7 to push the frame plate 6 to slide along the support plate 4 in the direction close to the T-shaped steel piece 29, which will drive the motor 8 to move, and the shift block 10 will also slide inside the swing rod 11 and increase the degree of inclination of the swing rod 11 to one side. Then, during the subsequent punching, the swing amplitude of the swing rod 11 will increase, and the quick return characteristic will be more obvious, and then when the thickness of the T-shaped steel piece 29 increases, the return efficiency will be faster, thereby improving the efficiency of punching;

[0038] After the first punching is completed, the conveying group conveys the T-shaped steel piece 29 from the back to the front for a certain distance, and then the punching operation can be carried out on the two ends of the T-shaped steel piece 29 of the second section (because there are two forming groups, punching will be carried out from the front and back during punching). When the second section is punching, the cutting disk 3 will cut the middle of the T-shaped steel piece 29 of the first section and the second section, thereby making the entire T-shaped steel piece 29 become a T-shaped steel piece 29 with punching completed section by section.

[0039] A transverse plate 14 is slidably connected to the baffle 5, and the bottom of the transverse plate 14 is wedge-shaped. Two contact blocks 15 are arranged below the transverse plate 14, and the tops of the two contact blocks 15 are both wedge-shaped. The two contact blocks 15 are respectively fixedly connected to the support plate 4 near the front and rear ends. A driving group is arranged on the right side of the contact block 15, and the driving group is used to control the relative position of the transverse plate 14 and the contact block 15 according to the size of the steel plate.

[0040] The driving group includes two support rods 16, a U-shaped rod 18 and a first spring 19. The two support rods 16 are rotatably connected to the front and rear sides of the forming part 13 respectively. The bottom ends of the two support rods 16 are slidably connected with slide grooves 17. The two slide grooves 17 are both opened on the support plate 4. The inner sides of the U-shaped rod 18 are opened with inclined surfaces and the two inclined surfaces are respectively in contact with the two support rods 16. The U-shaped rod 18 is fixedly connected to the end of the frame plate 6, the stopper 5 is slidably connected to the support plate 4, and the first spring 19 is fixedly connected between the stopper 5 and the inner wall of the support plate 4.

[0041] like Figure 5 , Figure 7-Figure 12 As shown:

[0042] Because the punching positions of T-shaped steel pieces 29 of different sizes need to be changed during punching, otherwise the punched holes will be lower as the size of the T-shaped steel piece 29 increases. Therefore, when the T-shaped steel piece 29 becomes larger, the thickness will also increase, and when the T-shaped steel piece 29 becomes larger, the cylinder 7 will extend the corresponding length (the larger the T-shaped steel piece 29, the longer the cylinder 7 extends). When the cylinder 7 pushes the frame plate 6 to move, it will drive the U-shaped rod 18 to move toward the direction of the stopper 5, and during the movement of the U-shaped rod 18, the inclined surface of the inner wall thereof will squeeze the two support rods 1 6. Move the two support rods 16 along the slide groove 17. At this time, the two support rods 16 will push the stopper 5 to slide along the support plate 4 toward the cylinder 7. At this time, the first spring 19 will be gradually compressed. When the stopper 5 and the forming member 13 drive the T-shaped steel member 29 to move, the inclined surface at the bottom of the cross plate 14 will slide against the inclined surface at the top of the contact block 15. At this time, the cross plate 14 will slide downward along the stopper 5. At this time, the larger T-shaped steel member 29 on the cross plate 14 will drop a certain distance, so that the punching position will not be too low during the subsequent punching.

[0043] Moreover, when the T-shaped steel part 29 becomes larger, the stopper 5 will slide according to the elongation state of the cylinder 7, and when the forming part 13 and the stopper 5 move, the distance between the two ends of the two support rods 16 inside the slide groove 17 will become smaller, so that when the T-shaped steel part 29 is punched, the support rod 16 will have a greater bearing capacity on the forming part 13 due to the smaller bottom end distance, thereby adapting to the problem of deformation of the forming part 13, the stopper 5 and the support rod 16 caused by the increase in stamping load when the T-shaped steel part 29 becomes larger.

[0044] An extension plate 20 is disposed in front of the transverse plate 14 . The rear end of the extension plate 20 is U-shaped and extends to the bottom end of the transverse plate 14 and is fixedly connected to the transverse plate 14 .

[0045] A limiting plate 21 is disposed outside the extension plate 20 . The extension plate 20 is located right in front of the blocking member 5 . The limiting plate 21 is fixedly connected to the side wall of the blocking member 5 .

[0046] like Figure 1 , Figure 11-Figure 12 As shown:

[0047] By setting up an extension plate 20, the extension plate 20 moves with the cross plate 14, and the limiting plate 21 is fixedly connected to the baffle 5, so when the baffle 5 moves, the limiting plate 21 will move with it, and the extension plate 20 will move with the cross plate 14, and the rear end of the extension plate 20 is U-shaped, so that the cutting disk 3 will not touch the limiting plate 21 and the cross plate 14 when performing a cutting operation. When the cutting disk 3 is cutting, the limiting plate 21 and the extension plate 20 can support the end of the T-shaped steel member 29 to avoid tilting and bending during cutting, which affects the cutting accuracy and efficiency.

[0048] As a further solution of the present invention, the two guide rods 22 are slidably connected with bent rods 23, the tops of the two baffles 5 are fixedly connected with positioning plates 26, the bent rods 23 are slidably connected with extrusion plates 24, and a second spring 25 is fixedly connected between the two bent rods 23 and the two extrusion plates 24.

[0049] The bottoms of the two bent rods 23 are provided with inclined surfaces. The two extrusion plates 24 and the side walls of the two positioning plates 26 are slidably connected with lower pressing blocks 27. The two lower pressing blocks 27 and the inner walls of the extrusion plates 24 and the positioning plates 26 are fixedly connected with third springs 28.

[0050] like Figure 4 , Figure 6-Figure 7 and Fig.10 As shown:

[0051] When the guide rod 22 moves to drive the punch head 2 to move, the bent rod 23 will follow the movement and drive the extrusion plate 24 to move toward the positioning plate 26. After the extrusion plate 24 contacts the positioning plate 26, the extrusion plate 24 will contact the T-shaped steel part 29 from the side of the T-shaped steel part 29 away from the positioning plate 26 and clamp the T-shaped steel part 29. At this time, the positioning plate 26 and the extrusion plate 24 will clamp the T-shaped steel part 29 from both sides respectively to ensure that the T-shaped steel part 29 will not warp in the subsequent punching process (because the T-shaped steel part 29 is mostly thin sheets, warping and bending will occur), and then the guide rod 22 continues to drive the punch head 2 to approach the T-shaped steel part 29, but At this time, the bent rod 23 will slide relative to the extrusion plate 24 and compress the second spring 25. When the second spring 25 is compressed, the inclined surface at the bottom of the bent rod 23 will contact the two pressing blocks 27 in turn, thereby driving the two pressing blocks 27 to descend along the positioning plate 26 and the extrusion plate 24 until the two pressing blocks 27 press down on the corners of the T-shaped steel piece 29, thereby pressing down and fixing the T-shaped steel piece 29, which can further improve the stability during punching. More importantly, the T-shaped steel piece 29 can be fixed from the rear of the cutting disk 3, so that when the cutting disk 3 is cutting, the thin T-shaped steel piece 29 will not bend or deform to affect the accuracy and efficiency of cutting.

[0052] After the punching is completed, the guide rod 22 is reset, and the bent rod 23 and the extrusion plate 24 are also reset.

[0053] The lower pressing blocks 27 are all L-shaped, and rubber blocks are glued to the bottoms of the lower pressing blocks 27 .

[0054] As shown in the figure: the rubber block can play a certain buffering role. Rubber blocks are common knowledge, so they are not introduced in detail.
