[0003] The car frame is the skeleton structure of the car, which supports various parts of the car, including the engine, suspension system, body, etc. The design and materials of the frame have a significant impact on the performance, safety, durability and cost of the car.

[0004] The truck frame carries the weight and load of the vehicle. The truck frame is mainly composed of beams, cross beams, brackets, supports and reinforcing beams. The frame beams are connected with cross beams and brackets mainly by riveting to ensure the overall strength of the frame. The frame beams and reinforcing beams are mainly made of special channel steel. When the special channel steel raw materials are processed into beams or cross beams, rivet holes need to be processed on the channel steel. For example, the patent with patent number CN201811322678.6 discloses a punching mechanism of a subframe, including a frame, a punching module arranged on the frame, the punching module including a module frame, a die assembly fixed on the module frame for setting up the subframe, a first punch assembly and a second punch assembly slidingly arranged on the module frame and respectively located on the left and right sides of the die assembly, a first driving device and a second driving device driving the first punch assembly and the second punch assembly to move toward the die assembly respectively and then punch and form holes on both sides of the subframe respectively, the first punch assembly and the second punch assembly both have an initial position, and the punching mechanism also includes a return mechanism driving the first punch assembly and the second punch assembly to return to the initial position.

[0005] The above mechanism cannot realize continuous punching of the vehicle frame, and at the same time, it is impossible to automatically replace different punch assemblies and die assemblies, and the hole making efficiency is low for the vehicle frame main beam that needs continuous punching.

[0006] Therefore, those skilled in the art are committed to developing a rapid punching device for an automobile frame, which is conducive to quickly and continuously processing the required rivet holes on the frame and improving the processing accuracy. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a rapid punching device for an automobile frame, which is conducive to rapidly and continuously processing required rivet holes on the frame and improving the processing accuracy. The technical solution of the present invention to solve the above technical problems is as follows: A quick hole punching device for a vehicle frame, comprising: Move components horizontally; A clamping assembly, which is installed at the moving end of the horizontal moving assembly and is used to clamp the channel steel; An upper die rotating assembly, wherein the upper die rotating assembly is mounted on a frame, and a plurality of upper die assemblies are mounted on the upper die rotating assembly; A lower die rotating assembly, the lower die rotating assembly is mounted on the frame and is located at the lower side of the upper die assembly, and a plurality of lower die assemblies adapted to the upper die assembly are mounted on the lower die rotating assembly; A hydraulic assembly is mounted on the frame, and an output end of the hydraulic assembly extends to the upper end of the upper mold assembly.

[0009] The beneficial effect of adopting the above scheme is that after the clamping assembly clamps the channel steel to be processed, the horizontal moving assembly drives the clamping assembly and the channel steel to move along the set route. After moving to the specified position, the upper die rotating assembly rotates the upper die assembly to a suitable position, and at the same time, the lower die rotating assembly rotates the lower die assembly to a suitable position. The upper die assembly and the lower die assembly cooperate and punch out the rivet hole under the action of the hydraulic assembly, thereby improving the processing rate of the rivet hole. Punching is used to make holes, which not only has high production efficiency, but also produces very consistent hole diameters, improving the processing accuracy of rivet holes and facilitating subsequent rivet connection. Different upper die assemblies and lower die assemblies are installed according to actual conditions, so that rivet holes of different shapes can be quickly processed. The operation is simple and no additional cutting tools are required, which further improves the efficiency of rivet hole processing.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the horizontal moving component includes a moving bracket, the clamping component is installed on the side wall of the moving bracket, a plurality of sliders and guide rails cooperating with the sliders are installed at the bottom of the moving bracket, the guide rails are installed on a base plate, a driving motor is installed on the base plate, a driving screw is installed at the output end of the driving motor, a screw bearing cooperating with the driving screw is installed on the moving bracket, and the driving screw is installed on the base plate through a screw mounting seat.

[0012] The beneficial effect of adopting the above further scheme is: the rotation of the driving motor drives the screw bearing to rotate, and then drives the movable bracket and the clamping device to move horizontally, thereby accurately controlling the horizontal movement distance of the channel steel, which is conducive to the subsequent upper mold assembly and the lower mold assembly to quickly process rivet holes on the channel steel.

[0013] Further, the clamping assembly includes a rotating member, a telescopic member, a connecting rod and a clamping member, the rotating member is installed on the horizontal moving assembly, the telescopic member is installed at the output end of the rotating member, the connecting rod and the clamping member are sequentially connected at the output end of the telescopic member, and the clamping member is used to clamp the side wall of the channel steel; A plurality of supporting rollers for supporting the channel steel are installed on the horizontal moving assembly.

[0014] The beneficial effect of adopting the above further scheme is: the clamping components on both sides of the movable bracket are used to clamp the channel steel. After the rotating part drives the telescopic part, the connecting rod and the clamping part to rotate to the appropriate position, the telescopic part drives the connecting rod and the clamping part to move, so that the clamping parts on both sides clamp the channel steel firmly.

[0015] Furthermore, the side wall of the movable bracket is connected to a mounting plate, and a plurality of electromagnet assemblies are mounted on the mounting plate.

[0016] The beneficial effect of adopting the above further scheme is: the electromagnet assembly absorbs the cross section of the channel steel to achieve lateral positioning, and at the same time cooperates with the supporting rollers on the lower side of the channel steel to accurately position the channel steel. At the same time, the electromagnet assembly is also used to bear the gravity of the channel steel, which also makes the clamping piece clamp firmly.

[0017] Furthermore, the upper mold rotating assembly includes an upper mold rotating disk, and the upper mold rotating disk is installed on the frame through a telescopic rotating assembly, and a plurality of upper mold assemblies are installed on the upper mold rotating disk.

[0018] The beneficial effect of adopting the above further scheme is: after the telescopic rotating assembly drives the upper mold rotating disk to rotate and rotate the appropriate upper mold assembly to the processing position, the telescopic rotating assembly is further extended downward so that the upper mold assembly is located on the channel steel, which is conducive to the subsequent processing of the rivet holes.

[0019] Furthermore, the upper die assembly comprises an upper die block, on which an upper die punch is mounted.

[0020] The beneficial effect of adopting the above further solution is: different upper die punches are designed according to different rivet holes.

[0021] Furthermore, the lower mold rotating assembly includes a lower mold rotating plate, on which are mounted a plurality of lower mold assemblies respectively cooperating with the upper mold assemblies. The lower mold rotating plate is mounted on a support seat via a rotating support bearing, and a rotating assembly is mounted on the lower side of the lower mold rotating plate.

[0022] The beneficial effect of adopting the above further scheme is that the rotating assembly drives the lower mold rotating disk to rotate, so that after the lower mold assembly cooperating with the upper mold assembly rotates to a suitable position, it is convenient for the subsequent upper mold assembly and the lower mold assembly to cooperate to process rivet holes on the channel steel.

[0023] Furthermore, the rotating assembly includes a rotating gear installed below the lower mold rotating disk, the rotating gear is meshedly connected with a driving gear, the driving gear is installed at the output end of the rotating motor, and the rotating motor is installed on the frame.

[0024] The beneficial effect of adopting the above further solution is that the rotation of the rotating motor drives the driving gear and the rotating gear to rotate, thereby driving the lower mold rotating disk to rotate.

[0025] Furthermore, the lower die assembly includes lower die blocks, and each of the lower die blocks has a lower die hole that cooperates with the upper die punch.

[0026] The beneficial effect of adopting the above further solution is that the lower die hole cooperates with the upper die punch to process a suitable rivet hole on the channel steel.

[0027] Furthermore, the hydraulic assembly includes a hydraulic cylinder, and an output end of the hydraulic cylinder is located directly above the upper die punch.

[0028] The beneficial effect of adopting the above further solution is that the delivery end of the hydraulic cylinder acts on the upper die punch, so that the upper die punch processes the rivet hole on the channel steel.

[0029] Furthermore, a first horizontal rod is installed on the frame, the end of the first horizontal rod is located at the lower side of the output end of the hydraulic assembly, the first horizontal rod is sequentially connected to the vertical rod and the second horizontal rod, the second horizontal rod is hingedly connected to the frame through a supporting hinge, the other end of the second horizontal rod is connected to a push rod through a hinge, and a piston head is installed on the upper end of the push rod; The lower die assembly has a discharge cavity, and the hydraulic assembly sequentially drives the first horizontal rod, the vertical rod, the second horizontal rod and the ejector rod to move so that the piston head moves up and down in the discharge cavity; An abutment spring is also installed between the lower side of the second horizontal rod and the frame.

[0030] The beneficial effect of adopting the above further scheme is that after the moving end of the hydraulic assembly extends a certain distance, it drives the first horizontal rod, the vertical rod, the second horizontal rod and the push rod to move in sequence, so that the piston head moves upward in the discharge chamber. Since the upper end of the discharge chamber is blocked by the channel steel, the air in the discharge chamber is compressed during the movement of the piston head, so that the hydraulic assembly has a certain back pressure during stamping, which is suitable for high-strength and complex-shaped stamping, thereby improving the surface quality of the stamped parts and reducing fracture and rebound. After the stamping is completed, the stamped debris may block the upper end of the discharge chamber, and the piston head moves downward under the action of the abutment spring, so that there is a certain vacuum in the discharge chamber, thereby sucking and discharging the debris in the upper end of the discharge chamber, reducing the clogging of the residue in the upper end of the discharge chamber.

[0031] Furthermore, a vibration diaphragm is installed at the end of the lower mold assembly and on the outer wall of one side abutting against the channel steel.

[0032] The beneficial effect of adopting the above further scheme is: the piston head moves upward in the discharge chamber and compresses the air in the discharge chamber. If a large crack appears between the upper end of the upper mold assembly and the surface of the channel steel (indicating that the surface of the channel steel is uneven), the compressed air will blow the vibrating diaphragm to vibrate, thereby detecting the flatness of the surface of the channel steel.

[0033] Furthermore, the upper end of the piston head is hemispherical, and the discharge cavity includes a first cavity, a second cavity, a third cavity and a fourth cavity arranged in sequence from top to bottom, the second cavity and the fourth cavity are gradually expanding, and the third cavity matches the lower end of the piston head.

[0034] The beneficial effect of adopting the above further solution is that when the piston head is located in the fourth cavity, the gap between the upper end and the fourth cavity is relatively large, which is conducive to the discharge of debris and residues. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the present invention, after the clamping assembly 2 clamps the channel steel 3 to be processed, the horizontal moving assembly 1 drives the clamping assembly 2 and the channel steel 3 to move along a set route. After moving to a specified position, the upper die rotating assembly 4 rotates the upper die assembly 6 to a suitable position, and at the same time, the lower die rotating assembly 7 rotates the lower die assembly 8 to a suitable position. The upper die assembly 6 and the lower die assembly 8 cooperate and punch out a rivet hole under the action of the hydraulic assembly 9, thereby improving the processing rate of the rivet hole. Punching is used to make holes, which not only has high production efficiency, but also produces very consistent hole diameters, improving the processing accuracy of rivet holes and facilitating subsequent rivet connection. Different upper die assemblies 6 and lower die assemblies 8 are installed according to actual conditions, so that rivet holes of different shapes can be quickly processed. The operation is simple and convenient, and no additional cutting tools are required, thereby further improving the efficiency of rivet hole processing.

[0044] like Figure 1 , Figure 2 As shown, in some embodiments, the horizontal moving component 1 includes a moving bracket 10, the clamping component 2 is installed on the side wall of the moving bracket 10, a plurality of sliders and a guide rail 11 matched with the sliders are installed at the bottom of the moving bracket 10, the guide rail 11 is installed on the bottom plate 12, and a driving motor 13 is installed on the bottom plate 12.

The side wall of the movable bracket 10 is connected to a mounting plate 21, and a plurality of electromagnet assemblies 22 are installed on the mounting plate 21.

[0046] During the processing, the channel steel 3 is placed on the supporting roller 20 and pushed to the appropriate position. After the rotating part 16 rotates to make the connecting rod 18 horizontal, the telescopic part 17 is telescoped so that the clamping part 19 clamps the two sides of the channel steel 3. Finally, the electromagnet assembly 22 is energized to electromagnetically adsorb the channel steel 3. The supporting roller 20, the clamping part 19 and the electromagnet assembly 22 cooperate to accurately position and clamp the channel steel 3, which is beneficial to the subsequent processing of the rivet holes.

Specifically, the upper die assembly 6 includes an upper module 25, on which an upper die punch 26 is installed. The position of the upper die punch 26 on the upper module 25 can be adjusted according to the punching requirements. The ends of the plurality of upper die punches 26 are in different shapes, which are used to process rivet holes of different shapes at different longitudinal positions of the channel steel 3, which is conducive to subsequent further riveting.

[0048] In the embodiment, the lower die rotating assembly 7 includes a lower die rotating disk 27, on which a plurality of lower die assemblies 8 respectively matched with the upper die assembly 6 are mounted, the lower die rotating disk 27 is mounted on a support seat 29 via a rotating support bearing 28, and a rotating assembly is mounted on the lower side of the lower die rotating disk 27. Specifically, the rotating assembly includes a rotating gear 30 fixedly mounted below the lower die rotating disk 27, the rotating gear 30 can be a helical gear, the rotating gear 30 is meshedly connected with a driving gear 31, the driving gear 31 also is a helical gear, the driving gear 31 is mounted at the output end of a rotating motor 32, the rotating motor 32 is a servo motor, the rotating motor 32 is mounted on the frame 5, and a rotating shaft and a supporting bearing are mounted between the rotating gear 30 and the support seat 29.

[0049] The lower die assembly 8 includes lower die blocks 33, each of which has a lower die hole that matches the upper die punch 26. In one embodiment, the hydraulic assembly 9 includes a hydraulic cylinder 34, and the output end of the hydraulic cylinder 34 is located directly above the upper die punch 26.

[0050] Embodiment 2 like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in the second embodiment, a first horizontal rod 35 is also installed on the frame 5, and the end of the first horizontal rod 35 is located at the lower side of the output end of the hydraulic assembly 9, specifically at the lower side of the output end of the hydraulic cylinder 34. The first horizontal rod 35 is connected with a vertical rod 36 and a second horizontal rod 37 in sequence, and a guide block is installed between the vertical rod 36 and the frame. The second horizontal rod 37 is hingedly connected to the frame 5 through a support hinge 38, and the support hinge 38 is closer to one side of the vertical rod 36. The other end of the second horizontal rod 37 is connected with a push rod 40 through a hinge 39, and a guide assembly is installed between the push rod 40 and the frame 5. A piston head 41 is installed at the upper end of the push rod 40, and the upper end of the piston head 41 is hemispherical. The lower mold assembly 8 has a discharge cavity 42, and a vibration diaphragm 44 is installed at the end of the lower mold assembly 8 and on the outer wall of one side abutting against the channel steel. The hydraulic assembly 9 sequentially drives the first horizontal rod 35, the vertical rod 36, the second horizontal rod 37 and the top rod 40 to move so that the piston head 41 moves up and down in the discharge cavity 42, and an abutment spring 43 is also installed between the lower side of the second horizontal rod 37 and the frame 5.

[0051] After the moving end of the hydraulic assembly 9 extends a certain distance, it drives the first horizontal rod 35, the vertical rod 36, the second horizontal rod 37 and the push rod 40 to move in sequence, so that the piston head 41 moves upward in the discharge chamber 42. Since the upper end of the discharge chamber 42 is blocked by the channel steel, the air in the discharge chamber 42 is compressed during the movement of the piston head 41, so that the hydraulic assembly 9 has a certain back pressure during stamping, which is suitable for high-strength and complex-shaped stamping, thereby improving the surface quality of stamped parts and reducing fracture and rebound; After the stamping is completed, the punched-out debris or the upper end of the discharge chamber 42 is blocked. The piston head 41 moves downward under the action of the abutment spring 43, so that there is a certain vacuum in the discharge chamber 42, thereby sucking and discharging the debris in the upper end of the discharge chamber 42, reducing the blockage of the residue in the upper end of the discharge chamber 42. The piston head 41 moves upward in the discharge chamber 42 and compresses the air in the discharge chamber 42. If a large crack appears between the upper end of the upper mold assembly 8 and the surface of the channel steel (indicating that the surface of the channel steel is uneven), the compressed air will blow the vibrating diaphragm 44 to vibrate, thereby detecting the flatness of the surface of the channel steel. When the piston head 41 is located in the fourth cavity 48, the gap between the upper end and the fourth cavity 48 is larger, which is conducive to the discharge of debris and residue.
