Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, specifically a multi-functional stamping machine. Background Technology

[0002] A stamping press is a forming and processing equipment used to apply external force to materials such as metal sheets, strips, tubes and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. It plays a vital role in the manufacturing industry. Some sheet metals need to be punched by stamping presses during production. When punching existing sheet metals, the choice is usually between two types of holes: round holes or strip holes.

[0003] However, existing sheet metal punching machines have limited punching capabilities, equipped with only one type of punching head for punching sheets. Therefore, they can only complete the punching of one type of hole. When strip sheets require punching both round and strip holes, it is necessary to change the punching head or the entire punching machine. This cannot meet the current punching requirements for strip sheets and affects the punching efficiency. Furthermore, most of the waste generated during sheet metal punching falls directly onto the machine's worktable and must be manually collected later, increasing the workload of the workers. Utility Model Content

[0004] To address the problem that existing sheet metal punching machines have limited punching capabilities, cannot meet the punching requirements of existing strip sheets, and affect sheet metal punching efficiency, the purpose of this utility model is to provide a multi-functional punching machine.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a multi-functional stamping machine, including a mounting frame, a driving device fixedly mounted on one side of the mounting frame, the driving device including a fixed frame, a motor fixedly mounted on one side of the fixed frame, a lead screw fixedly mounted on the output end of the motor, a sliding sleeve threaded on the surface of the lead screw, a pressing device fixedly mounted on one side of the sliding sleeve, the pressing device including a mounting bracket, the mounting bracket being slidably mounted on the upper part of the mounting frame via the driving device, a hydraulic cylinder fixedly mounted on the bottom surface of the mounting bracket, a pressing seat fixedly mounted on the output end of the hydraulic cylinder, symmetrical feed ports on both sides of the mounting frame, and punching and stamping components symmetrically mounted inside the mounting frame;

[0006] The number of punching and stamping assemblies is two. Each punching and stamping assembly includes a fixing component and a lifting platform. The fixing components are rectangularly distributed within the mounting frame and located above the feed inlet. Guide rods are fixedly connected between the two fixing components. There are four guide rods in each punching and stamping assembly. The lifting platform is slidably sleeved on the surface of the four guide rods. Each of the four guide rods is fitted with a return spring on the lower surface of the lifting platform. The return springs cooperate with the lifting platform. A circular stamping head and a strip stamping head are respectively fixedly installed in the middle of the bottom surface of the lifting platform of the two punching and stamping assemblies.

[0007] Preferably, two placement platforms are fixedly installed below the feed inlet within the mounting frame. A circular discharge hole and a strip-shaped discharge hole are respectively opened in the middle of the top surface of each placement platform. The circular discharge hole cooperates with a circular stamping head, and the strip-shaped discharge hole cooperates with a strip-shaped stamping head. A collection box is installed below each of the two placement platforms within the mounting frame. The collection boxes are slidably installed on the bottom surface of the mounting frame. Two collection boxes are provided, and a handle groove is opened in the middle of one side of each collection box.

[0008] Preferably, auxiliary platforms are fixedly installed on both sides of the mounting frame, and there are two auxiliary platforms. The top surface of the auxiliary platforms is parallel to the top surface of the placement platform. Guide sleeves are symmetrically installed on the top surface of the mounting frame. Fixed grooves are symmetrically opened on the top surface of the mounting frame. Guide rails are fixedly installed in the fixed grooves. There are two guide rails and two guide sleeves. The two guide sleeves are slidably installed on the surfaces of the two guide rails respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, the pressing device is driven by the driving device to switch between the two punching components. The pressing device controls the two punching components to drive the corresponding circular or strip punching head to complete the punching work of different holes in the plate, saving time and improving the punching efficiency of the plate. It solves the problem that the existing punching machine for plate punching has a relatively simple punching function and can only complete the punching work of one type of hole.

[0011] 2. In this utility model, the waste material stamped by the circular stamping head and the strip stamping head falls into the corresponding collection box through the corresponding circular discharge hole and the strip discharge hole for collection. When the collection box is full, it can be removed from the bottom of the mounting frame through the handle groove for replacement. There is no need to manually collect the stamping waste later, which reduces the workload of the staff. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5As shown, this utility model provides a multi-functional stamping machine, including a mounting frame 1. A drive device 2 is fixedly mounted on one side of the mounting frame 1. The drive device 2 includes a fixed frame 21. A motor 22 is fixedly mounted on one side of the fixed frame 21. A lead screw 23 is fixedly mounted on the output end of the motor 22. A sliding sleeve 24 is threaded onto the surface of the lead screw 23. A pressing device 3 is fixedly mounted on one side of the sliding sleeve 24. The pressing device 3 includes a mounting bracket 31. The mounting bracket 31 is slidably mounted on the upper part of the mounting frame 1 through the drive device 2. A hydraulic cylinder 32 is fixedly mounted on the bottom surface of the mounting bracket 31. A pressing seat 33 is fixedly mounted on the output end of the hydraulic cylinder 32. Feed inlets 11 are symmetrically opened on both sides of the mounting frame 1. Two punching and stamping assemblies 4 are symmetrically installed inside the mounting frame 1. Each punching and stamping assembly 4 includes a fixing member 41 and a lifting platform 44. The fixing members 41 are rectangularly distributed inside the mounting frame 1 and located above the feed inlet 11. A guide rod 42 is fixedly connected between the two fixing members 41. There are four guide rods 42 in one punching and stamping assembly 4. The lifting platform 44 is slidably sleeved on the surface of the four guide rods 42. Each of the four guide rods 42 is fitted with a return spring 43 on the lower surface of the lifting platform 44. The return spring 43 cooperates with the lifting platform 44. A circular stamping head 5 and a strip stamping head 6 are fixedly installed in the middle of the bottom surface of the lifting platform 44 of the two punching and stamping assemblies 4, respectively.

[0021] The drive unit 2 is fixed on one side of the mounting frame 1 by the fixed frame 21. The drive unit 2 drives the pressing device 3 to switch above the two punching components 4. The pressing device 3 controls the two punching components 4 to drive the corresponding circular punching head 5 or strip punching head 6 to complete the punching of different holes in the sheet metal. When it is necessary to punch a circular hole in the sheet metal, the switch of the motor 22 in the drive unit 2 is turned on. The motor 22 controls the lead screw 23 to rotate. When the lead screw 23 rotates, it controls the sliding sleeve 24 to drive the mounting frame 31 of the pressing device 3 to move. When the mounting frame 31 moves to the top of the lifting platform 44 in the left punching component 4 in the mounting frame 1, the drive unit 2 stops working. The sheet metal that needs to be punched with a circular hole is placed on the left placement platform 7 in the mounting frame 1 through the feed port 11. The punching position of the sheet metal is placed directly below the circular punching head 5. After placement, the hydraulic pressure in the pressing device 3 is turned off. When cylinder 32 operates, it controls the pressing seat 33 to descend. With the cooperation of four guide rods 42, the descending pressing seat 33 controls the lifting platform 44 to drive the circular punch head 5 to descend, completing the punching work of the circular hole in the sheet metal. After the punching is completed, the pressing seat 33 in the pressing device 3 rises and returns to its initial state. At the same time as the pressing seat 33 rises, with the assistance of the return springs 43 installed on the surface of the four guide rods 42, the lifting platform 44 is controlled to rise. The circular punch head 5 follows the lifting platform 44 to rise and returns to its initial state to wait for the next punching. Similarly, when it is necessary to punch strip holes in the sheet metal, the sheet metal to be punched with circular holes is placed on the right-side placement platform 7 in the mounting frame 1 through the feed port 11. The pressing device 3 is moved by the driving device 2 to be directly above the lifting platform 44 in the right-side punching assembly 4 in the mounting frame 1 to control the strip punch head 6 to punch the strip holes in the sheet metal.

[0022] Inside the mounting frame 1, below the feed inlet 11, two placement platforms 7 are fixedly installed. Each placement platform 7 has a circular discharge hole 51 and a strip-shaped discharge hole 61 respectively on its top surface. The circular discharge hole 51 cooperates with a circular punch head 5, and the strip-shaped discharge hole 61 cooperates with a strip-shaped punch head 6. Below each of the two placement platforms 7, two collection boxes 9 are installed inside the mounting frame 1. These collection boxes 9 are slidably installed on the bottom surface of the mounting frame 1. Each collection box 9 has a [missing information - likely a design element or feature] on one side. There is a handle groove 91. Two placement platforms 7 assist the corresponding circular stamping head 5 and strip stamping head 6 in stamping the sheet metal. The circular blanking hole 51 and strip blanking hole 61 are located directly below the corresponding circular stamping head 5 and strip stamping head 6, respectively. The waste material stamped by the circular stamping head 5 and strip stamping head 6 falls into the corresponding collection box 9 through the corresponding circular blanking hole 51 and strip blanking hole 61 for collection. When the collection box 9 is full, it can be removed from the bottom of the mounting frame 1 through the handle groove 91 for replacement.

[0023] Two auxiliary platforms 8 are fixedly installed on both sides of the mounting frame 1. The top surface of the auxiliary platform 8 is parallel to the top surface of the placement platform 7. The auxiliary platforms 8 installed on both sides of the mounting frame 1 assist the placement platform 7 in placing the sheet metal, thereby increasing the stability of the sheet metal during punching.

[0024] The top surface of the mounting bracket 31 is symmetrically equipped with guide sleeves 311. The top surface of the mounting frame 1 is symmetrically provided with fixing grooves 13. Guide rails 34 are fixedly installed in the fixing grooves 13. There are two guide rails 34 and two guide sleeves 311. The two guide sleeves 311 are slidably installed on the surfaces of the two guide rails 34 respectively. The two guide rails 34 are installed and fixed by the two fixing grooves 13 respectively. With the cooperation of the two guide rails 34 and the two guide sleeves 311, the pressing device 3 is assisted to move, increasing the stability of the pressing device 3 when moving, and at the same time completing the guiding work of the pressing device 3. A through groove 12 is provided on one end of the mounting frame 1. The through groove 12 is interconnected with the fixing frame 21. The sliding sleeve 24 is slidably installed in the through groove 12, and the sliding sleeve 24 is assisted to move by the through groove 12.

[0025] Two bearings 231 are fitted at both ends of the lead screw 23. The two bearings 231 are fixedly installed on both sides of the fixed frame 21. The bearings 231 cooperate with the lead screw 23 to complete the installation and positioning of the lead screw 23 in the fixed frame 21, and at the same time assist the lead screw 23 in rotation, increasing the stability of the lead screw 23 during rotation. Positioning parts 14 are fixedly installed on both ends of the mounting frame 1. There are four positioning parts 14. Each of the four positioning parts 14 has a positioning hole 141. The positioning holes 141 in the four positioning parts 14 are used in conjunction with corresponding bolts to complete the installation and fixation of this device on the designated machine tool, which is used for stamping sheet metal.

[0026] Working principle: When it is necessary to punch circular holes in the sheet metal, turn on the switch of the motor 22 in the drive device 2. The motor 22 controls the lead screw 23 to rotate. When the lead screw 23 rotates, it controls the sliding sleeve 24 to drive the mounting frame 31 of the pressing device 3 to move. When the mounting frame 31 moves to the top of the lifting platform 44 in the punching assembly 4 on the left side of the mounting frame 1, the drive device 2 stops working. The sheet metal that needs to be punched with circular holes is placed on the left side placement platform 7 in the mounting frame 1 through the feed port 11.

[0027] The hole-punching position of the sheet metal is placed directly below the circular punch head 5. After placement, the hydraulic cylinder 32 inside the pressing device 3 operates, controlling the pressing seat 33 to descend. With the cooperation of the four guide rods 42, the descending pressing seat 33 controls the lifting platform 44 to drive the circular punch head 5 to descend, completing the punching work of the circular hole in the sheet metal. After punching, the pressing seat 33 inside the pressing device 3 rises and returns to its initial state. At the same time as the pressing seat 33 rises, with the assistance of the return springs 43 installed on the surface of the four guide rods 42, the lifting platform 44 is controlled to rise. The circular punch head 5 follows the lifting platform 44 to rise, returning to its initial state and waiting for the next punching.

[0028] Similarly, when it is necessary to punch strip holes in the sheet material, the sheet material for which circular holes need to be punched is placed on the right-side placement platform 7 inside the mounting frame 1 through the feed port 11. The pressing device 3 is moved by the drive device 2 to be directly above the lifting platform 44 inside the right-side punching assembly 4 inside the mounting frame 1 to control the strip punching head 6 to perform the punching work of strip holes in the sheet material.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
