[0029] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0031] like Figures 1 to 7 As shown, the present invention discloses a multi-hole cutting device for a front suspension beam of an automobile, comprising a base plate 1 and a punching mechanism arranged on the base plate 1, wherein the punching mechanism comprises a fixing plate 2, a positioning plate 3 and two hydraulic punching modules symmetrically arranged on the upper and lower surfaces of the fixing plate 2, respectively; the positioning plate 3 is arranged on the upper surface of the fixing plate 2, and a pushing cylinder 4 is arranged at the rear end thereof for driving it to slide between the two hydraulic punching modules; the front end of the positioning plate 3 has a positioning block 301, and the positioning block 301 has a hydraulic pressure plate 4 for driving the hydraulic pressure plate 4 to slide between the two hydraulic pressure plate 4; ... hydraulic pressure plate 4 for driving the hydraulic pressure plate 4 to slide between the two hydraulic pressure plate 4; the positioning plate 3 has a hydraulic pressure plate 4 for driving the hydraulic pressure plate 4 to slide between the two hydraulic pressure plate 4; the positioning plate 3 has a hydraulic pressure plate 4 for driving the hydraulic pressure plate 4 to slide between the two hydraulic pressure plate The punch 5 of the pressure punching module passes through the through hole 302. In the first state, the pushing cylinder 4 drives the positioning block 301 to move forward so that the through hole 302 is opposite to the punch 5. At this time, a slot 6 is formed between the upper and lower surfaces of the positioning block 301 and the two hydraulic punching modules. The workpiece to be punched is inserted into the slot 6 and clamped with the positioning block 301, and the two hydraulic punching modules punch synchronously; in the second state, the pushing cylinder 4 drives the positioning block 301 to move backward to separate it from the workpiece to be punched.

[0032] Specifically, each of the hydraulic punching modules further comprises a hydraulic cylinder 7 and a driving block 8, each of the hydraulic cylinders 7 is arranged on a first mounting plate 9, each of the driving blocks 8 is arranged on a second mounting plate 10, the punch 5 is fixedly connected to the driving block 8, and the driving block 8 has a socket 801 matching the driving rod 701 of the hydraulic cylinder 7. The hydraulic cylinder 7 drives its hydraulic rod 701 to extend into the socket 801 and abut against the driving block 8, so as to drive the driving block 8 to drive the punch 5 to perform punching synchronously, and when the driving block 8 moves, it will drive the second mounting plate 10 to move synchronously, so as to improve the stability of the punch 5 pressing down. The present invention symmetrically arranges two identical hydraulic punching modules in the upper and lower parts to maximize the consistency and synchronization of the upper and lower punching. In order to ensure that the hydraulic punching modules are aligned with each other in the upper and lower parts, a group of guide columns 201 are fixedly arranged on the fixed plate 2, and each of the guide columns 201 passes through the first mounting plate 9, the second mounting plate 10 and the fixed plate 2. The guide column 201 is arranged at the corner, which further ensures the synchronous movement of the upper and lower hydraulic punching modules and the fixed plate 2.

[0033] In the illustrated embodiment, each of the hydraulic punching modules has two punches 5. The two punches 5 may have different diameters or outer contours. In other feasible embodiments, the hydraulic punching module may have more than two punches 5. The number of the punches 5 is set according to specific punching requirements.

[0034] like Figures 3 to 6 As shown, a guide block 11 is arranged between the two hydraulic punching modules, and the guide block 11 is composed of an upper part 1101 and a lower part 1102. The front ends of the upper part 1101 and the lower part 1102 have guide holes for each punch 5 to pass through, so that the punch 5 can pass through the upper part 1101 and the lower part 1102. The fixed plate 2 is fixedly arranged on the inner end surface of the lower part 1102, and the positioning plate 3 is located between the upper part 1101 and the fixed plate 2. The slot 6 is formed between the inner surfaces of the front ends of the upper part 1101 and the lower part 1102 and the upper and lower surfaces of the positioning block 301. On the one hand, the guide block 11 can limit the punch 5 to pass through the guide hole, and play a guiding role in its punching direction; on the other hand, it can limit the positioning plate 3 to slide between the upper part 1101 and the fixed plate 2, and play a guiding role in its sliding direction, thereby improving the accuracy of the overall equipment when punching.

[0035] Furthermore, a positioning cylinder 12 is also provided on the upper part 1101, and a positioning hole 303 is provided on the positioning plate 3. When the positioning block 301 moves forward so that the through hole 302 is aligned with the punch 5, the cylinder head of the positioning cylinder 12 is inserted into the positioning hole 303 to fix the position of the positioning plate 3. The positioning plate 3 has two positioning holes 303, one of which is used for positioning when the positioning plate 3 moves forward to ensure that the through hole 302 is aligned with the punch 5; and the other positioning hole 303 is used for positioning when the positioning plate 3 moves backward to ensure that the through hole 302 is aligned with the ejector rod 17. The second mounting plate 10 located above the fixing plate 2 has a notch for the positioning cylinder 12 to avoid the position.

[0036] In order to further improve the sliding stability of the positioning plate 3, a latch 13 is inserted between the upper part 1101, the positioning plate 3 and the fixed plate 2, and a waist-shaped hole 304 is provided on the positioning plate 3 in the same direction of movement, and the latch 13 passes through the waist-shaped hole 304. Such a structure allows the latch 13 to always penetrate the upper part 1101, the positioning plate 3 and the fixed plate 2, ensuring that the upper part 1101 and the fixed plate 2 are not affected by the sliding of the positioning plate 3 and remain motionless, and the setting of the waist-shaped hole 304 allows the latch 13 to not affect the sliding of the positioning plate 3.

[0037] like Figure 1 , Figure 2 As shown, the punching mechanism is fixed on a bottom plate 14, the base plate 1 has a strip hole 101 through which the punching mechanism can pass, and the base plate 1 is provided with slide rails 102 on both sides of the strip hole 101, and the base plate 14 is slidably arranged on the slide rails 102 and can move relative to the base plate 1 under the drive of the driving cylinder 18. Such a structure allows the base plate 1 to not affect the operation of the hydraulic punching module located below the fixed plate 2, and allows the punching mechanism to slide relative to the base plate 1.

[0038] At the same time, if Figure 3 , Figure 5As shown, a bracket 103 and a waste collection box 15 are provided on the first side 1011 of the strip hole 101, and the extension direction of the bracket 103 is consistent with the moving direction of the bottom plate 14. The extension end of the bracket 103 is pivotally connected to the front end of the waste collection box 15. When the bottom plate 14 is located on the first side 1011, the waste collection box 15 extends into the interior of the punching mechanism and is supported by the second mounting plate 10 in a horizontal state; when the bottom plate 14 moves toward the second side 1012 of the strip hole 101, the punching mechanism moves away from the waste collection box 15, and the tail end of the waste collection box 15 falls freely to make it in a tilted state. The waste collection box 15 and the bracket 103 are only pivotally arranged at the front end, so that the waste collection box 15 can rotate relative to the extended end of the bracket 103. At the same time, in cooperation with the sliding of the punching mechanism, the waste collection box 15 switches between waste collection in a horizontal state and waste dumping in an inclined state as the punching mechanism slides, so that the waste collection box 15 does not need to be manually disassembled to dump the waste, which greatly improves the automation of waste collection and improves the efficiency of the overall equipment operation.

[0039] In order to facilitate the collection and dumping of waste, the front end and the rear end of the waste collection box 15 are both open, so that the waste in the waste collection box 15 can be naturally dumped in its tilted state.

[0040] In order to ensure that the waste generated by punching falls into the waste collection box 15, an inclined waste circulation groove 16 is provided between the fixed plate 2 and the lower part 1102, and the upper end of the waste circulation groove 16 is located below the positioning plate 3, and the lower end of the waste circulation groove 16 is located at the front end opening of the waste collection box 15, and its inclined structure facilitates the waste to fall into the waste collection box 15 from the through hole 302.

[0041] Furthermore, the top of the waste circulation groove 16 has a push rod 17 that matches the through hole 302. The push rod 17 is fixedly connected to the driving block 8 and driven downward by the hydraulic cylinder 7. Such a structure allows the hydraulic cylinder 7 to drive the push rod 17 downward without the need to set up an additional driving mechanism, which simplifies the equipment structure and reduces production costs. In addition, the setting of the push rod 17 ensures that the waste in the through hole 302 is ejected into the waste circulation groove 16, avoiding the waste from being stuck in the through hole 302 and causing the next punching failure, and also improving the efficiency of waste falling. In order to prevent the positioning plate 3 from hindering the downward pressure of the push rod 17 when the driving block 8 drives the punch 5 to punch, a second through hole 305 opposite to the push rod 17 is provided on the positioning plate 3.

[0042] The present invention arranges the hydraulic punching module symmetrically up and down, and slides the positioning plate 3. The positioning plate 3 is moved to engage with the workpiece to be punched for precise positioning, so that the workpiece to be punched can complete the punching process of multiple holes up and down at one time, greatly improving the production efficiency. At the same time, a waste collection box 15 is arranged to integrate punching and waste collection, further improving the automation and efficiency of the punching process.

[0043] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0044] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
