Description

Technical Field

[0001] This invention relates to the field of stamping technology, specifically to a stamping material handling device, a stamping part handling method, and a workstation transfer method. Background Technology

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal or strip material to deformation force in a die, thereby obtaining product parts with a certain shape, size and performance.

[0003] Traditional stamping equipment generally includes a stamping mechanism, a blanking die, and a machine base. During stamping, the stamping mechanism drives the blanking die to perform a punching action, which completes the punching operation.

[0004] Traditional stamping equipment can only perform cutting operations. When the cut sheets need to be installed at the next station, a separate unloading device is required to remove the sheets from the cutting station and place or install them at the desired station. This inevitably complicates the entire production process and significantly increases the equipment's production cost. Furthermore, it occupies more installation space, further increasing production costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a stamping material handling device, a stamping part handling method, and a workstation transfer method that can connect with flexible workpieces to achieve integrated stamping, material handling, and material transfer, thereby reducing production processes, improving the accuracy of material handling and assembly, and reducing production costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping material handling device, comprising:

[0007] frame;

[0008] A stamping device includes a stamping mechanism, a take-up sleeve, a blanking die, and a machine base. The stamping mechanism and the machine base are arranged opposite to each other on a frame. The blanking die is mounted on the machine base and has a through-hole. The take-up sleeve is mounted on the stamping mechanism and can be inserted into the blanking hole. During the pressing process, the stamping mechanism applies pressure to the blanking die to blank the sheet material located in the blanking hole, and the length of the cut flexible workpiece is at least greater than the inner diameter of the take-up sleeve in one direction.

[0009] The material handling device includes a first pushing mechanism, which is disposed on the frame. The first pushing mechanism is used to push the punched workpiece into the punching hole so that the workpiece is bent and deformed and locked in the material handling sleeve.

[0010] Furthermore, the blanking die includes an elastic support member, an inner die, and an outer die. The inner die is fixed on the machine base, and the inner cavity of the outer die is a blanking hole. The elastic support member is disposed between the machine base and the outer die to provide elastic support for the outer die.

[0011] Furthermore, the elastic support includes an elastic telescopic member and a guide post. The guide post is fixed on the machine base and can slide through the outer mold. The elastic telescopic member is slidably sleeved on the guide post and supported between the machine base and the outer mold.

[0012] Furthermore, the size of the end of the material taking sleeve near the outer mold is adapted to the size of the punching hole, and the outer wall of the material taking sleeve is provided with an outwardly protruding pressing step.

[0013] Furthermore, it also includes a feeding mechanism, which is mounted on the frame and connected to the stamping mechanism, for driving the stamping mechanism to move from the punching station to the next station.

[0014] Furthermore, the feeding mechanism includes a movable mounting plate and a movable drive source. The movable drive source is mounted on the frame, and the movable mounting plate is on the power output shaft of the movable drive source. The movable drive source can drive the movable mounting plate to move to a lower station, and the stamping mechanism is mounted on the movable mounting plate.

[0015] Furthermore, the first pushing mechanism includes a loading telescopic power source and a support plate. The inner mold has an installation hole on its end face facing the material taking sleeve. The loading telescopic power source is disposed in the installation hole. The support plate is disposed on the telescopic shaft of the support plate. The loading telescopic power source can drive the support plate to extend into the punching hole.

[0016] Furthermore, the material handling device also includes a second pushing mechanism, which includes a pressing telescopic power source and a pressure plate. The pressing telescopic power source is disposed in the inner hole of the material handling sleeve, and the pressure plate is disposed on the telescopic shaft of the pressing telescopic power source. The pressing telescopic power source can drive the pressure plate to rise and fall perpendicularly to the machine platform.

[0017] A method for unloading stamped parts, employing the aforementioned stamping unloading device, includes:

[0018] A flexible sheet-like workpiece with a length greater than the inner diameter of the take-up sleeve in at least one direction is punched out using a punching die.

[0019] After punching is completed, the workpiece is pushed into the inner hole of the take-up sleeve by the first pusher mechanism, and the workpiece is stuck in the inner hole of the take-up sleeve by the bending deformation of the workpiece.

[0020] A workstation transfer method, employing the aforementioned stamping part relocation method, further includes:

[0021] The material handling sleeve has been moved to the next station by moving the moving mounting plate driven by the moving drive source.

[0022] The workpiece stuck in the inner hole of the material receiving sleeve is pushed out by the second pushing mechanism.

[0023] The beneficial effects of the above-mentioned stamping material handling device, stamping part handling method, and station transfer method are as follows:

[0024] The stamping device includes a stamping mechanism, a take-up sleeve, a blanking die, and a machine base. The stamping mechanism and the machine base are arranged opposite each other on the machine frame. The blanking die is installed on the machine base and has a through blanking hole. The take-up sleeve is installed on the stamping mechanism and can be inserted into the blanking hole. During the pressing process, the stamping mechanism can apply pressure to the blanking die to blank the strip located in the blanking hole, and the length of the flexible workpiece punched out is at least greater than the inner diameter of the take-up sleeve in one direction. The take-up device includes a first pushing mechanism, which is arranged on the machine frame. The first pushing mechanism is used to push the blanked workpiece into the blanking hole so that the workpiece bends and deforms and is stuck in the take-up sleeve.

[0025] In use, when the strip is placed inside the blanking die, the stamping mechanism drives the blanking die to perform blanking and shearing. Subsequently, the material handling device picks up the blanked sheet and returns it to the material handling sleeve. After the blanking die moves to the next station, the material handling device pushes the sheet to the next station for installation or processing. This stamping part handling device is used for both the blanking part handling method and the station transfer method.

[0026] This punching device, material handling, and station transfer method eliminates the need for additional material handling equipment. It integrates punching, material handling, and material transfer into one unit, avoiding repeated positioning. This reduces production processes, improves the accuracy of material handling and assembly, and reduces production costs. Attached Figure Description

[0045] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0046] Please see Figures 1 to 11 The present invention provides a stamping material handling device, including a frame 100, a stamping device 200 and a material handling device 300.

[0047] Please see Figures 1 to 8 Specifically, the stamping device 200 includes a stamping mechanism 210, a take-up sleeve 220, a blanking die 230, and a machine base 240. The stamping mechanism 210 and the machine base 240 are arranged opposite to each other on the frame 100. The blanking die 230 is mounted on the machine base 240 and has a through blanking hole 231. The take-up sleeve 220 is mounted on the stamping mechanism 210 and can be inserted into the blanking hole 231. During the pressing process, the stamping mechanism 210 can apply pressure to the blanking die 230 to blank the strip 1 located in the blanking hole 231, and the length of the cut flexible workpiece is at least greater than the inner diameter of the take-up sleeve 220 in one direction.

[0048] The material handling device 300 includes a first pushing mechanism 310. The first pushing mechanism 310 is mounted on the frame 100 and is used to push the punched workpiece into the punching hole 231 so that the workpiece is bent and deformed and locked in the material handling sleeve 220.

[0049] When in use, when the strip 1 is placed on the blanking die 230, the stamping mechanism 210 starts to move towards the machine table 240 to drive the blanking die 230 to perform blanking and cutting. Subsequently, the material taking device 300 grabs the blanked sheet back into the material taking sleeve 220. Since the workpiece is a flexible sheet, during the blanking process, it can be stretched and squeezed, thereby causing the edge of the workpiece to flare outward, and thus making the length of the workpiece at least in one direction greater than the diameter of the material taking sleeve 220. After the material taking device 300 grabs the blanked sheet back into the material taking sleeve 220, the workpiece will be temporarily stored in the material taking sleeve 220.

[0050] This device eliminates the need for additional material handling equipment. It integrates punching and material handling, reducing both production processes and costs.

[0051] In practical implementation, the stamping mechanism 210 can be a cylinder, hydraulic cylinder, lead screw, or other mechanism that can achieve linear pressurization.

[0052] In this embodiment, the blanking die 230 includes an elastic support member 232, an inner die 233, and an outer die 234. The inner die 233 is fixed on the machine base 240, and the inner cavity of the outer die 234 is a blanking hole 231. The elastic support member 232 is disposed between the machine base 240 and the outer die 234 to provide elastic support for the outer die 234.

[0053] When in use, when the strip 1 is located between the inner die 233 and the outer die 234, the stamping mechanism 210 starts to drive the outer die 234 to move towards the inner die 233. The outer die 234 and the inner die 233 cooperate to perform punching and shearing actions. At the same time, the outer die 234 presses the elastic support member 232 to compress. When the pressure is released, the elastic support member 232 can drive the outer die 234 to return to its original position.

[0054] In this embodiment, the elastic support 232 is disposed on the machine base 240 and supported at the bottom of the outer mold 234.

[0055] In practical implementation, a stripper plate 235 can also be connected to the bottom of the outer mold 234. The stripper plate 235 is fitted onto the inner mold 233, and a through hole is formed between the contact surfaces of the stripper plate 235 and the outer mold 234 to allow the strip 1 to pass through smoothly. An elastic support member 232 is supported at the bottom of the stripper plate 235. See the detailed structure for further details. Figure 4 The stripper plate 235 has a through hole in its center, coaxially arranged with the same size as the punching hole 231 of the outer mold 234. The stripper plate 235 is slidably fitted onto the inner mold 233 through this through hole, thus forming a posture where the stripper plate 235 and the outer mold 234 are integrated and fitted onto the inner mold 233. This significantly improves the guiding effect of the outer mold 234 during the punching and lifting process, enhancing the mold's impact resistance and facilitating better maintenance of punching accuracy. During use, allowing the strip 1 to pass through the through hole improves the smoothness of its movement. Furthermore, during mold opening and closing, the strip 1 within the through hole rises and falls synchronously with the outer mold 234, allowing the strip 1 to maintain a smooth posture while better cooperating with punching and stripping.

[0056] In this embodiment, the elastic support 232 includes an elastic telescopic member 2321 and a guide post 2322. The guide post 2322 is fixed on the machine base 240 and can slide through the outer mold 234. The elastic telescopic member 2321 is slidably sleeved on the guide post 2322 and supported between the machine base 240 and the outer mold 234.

[0057] The elastic telescopic component 2321 can support the outer mold 234, while the guide post 2322 can guide the movement of the outer mold 234.

[0058] In this embodiment, the size of the end of the material taking sleeve 220 near the outer mold 234 is adapted to the size of the punching hole 231, and the outer wall of the material taking sleeve 220 is provided with an outwardly protruding pressing step.

[0059] When the take-up sleeve 220 descends and inserts into the punching hole 231 of the outer mold 234, as the take-up sleeve 220 continues to descend, when the pressing step abuts against the upper mold, the outer mold 234 can be driven to descend.

[0060] By separating the functions of the blanking die 230 and the material take-up sleeve 220 in this way, the blanking die 230 performs the cutting action, while the material take-up sleeve 220 performs the material storage action. This reduces the wear on the opening of the material take-up sleeve 220, thereby extending the life of the material take-up sleeve 220 and consequently extending the life of the entire device. At the same time, the blanking die 230 is mounted as a detachable module on the machine base 240, facilitating easy replacement and maintenance, and better maintaining the precision of the blanking die 230.

[0061] See Figures 9 to 11 As a more preferred embodiment, the device further includes a feeding mechanism 400, which is mounted on the frame 100 and connected to the stamping mechanism 210, for driving the stamping mechanism 210 to move from the punching station to the next station.

[0062] Specifically, the feeding mechanism 400 includes a movable mounting plate 410 and a movable drive source 420. The movable drive source 420 is mounted on the frame 100, and the movable mounting plate 410 is on the power output shaft of the movable drive source 420. The movable drive source 420 can drive the movable mounting plate 410 to move to the next work station.

[0063] In practical implementation, the mobile drive source 420 can be a cylinder, hydraulic cylinder, lead screw or other mechanism capable of linear drive, or it can be a curve-advancing or rotary mechanism.

[0064] When the mobile drive source 420 is a mechanism such as a cylinder, hydraulic cylinder, or lead screw that can perform linear drive, the end of the mobile mounting plate 410 that is away from the punching die 230 can be slidably supported on the frame 100, which can improve the movement stability of the mobile mounting plate 410.

[0065] Please see Figures 3 to 8 In this embodiment, the first feeding mechanism 310 includes a loading telescopic power source 311 and a support plate 312. The inner mold 233 has a mounting hole on its end face facing the material take-up sleeve 220, and the loading telescopic power source 311 is disposed within the mounting hole. The support plate 312 is disposed on its telescopic shaft, and the loading telescopic power source 311 can drive the support plate 312 to extend into the punching hole 231.

[0066] After punching is completed, the loading telescopic power source 311 drives the support plate 312 to push the workpiece into the inner hole of the picking sleeve 220. Based on the flexible sheet material's own certain stretching capacity, when the edge of the workpiece moves upward close to the side wall of the inner hole of the picking sleeve 220, it forms a downward bending deformation of the edge. After the first pushing mechanism 310 retracts, the workpiece forms an upward arch with a certain elastic force and is naturally stuck in the picking sleeve 220.

[0067] It should be noted that, in specific implementation, the inner hole of the material-receiving sleeve 220 can be a straight shape with the same size at the top and bottom, or it can have an inward-retracting structure. A limiting step can also be set inside the inner hole of the material-receiving sleeve 220. The structure is sufficient as long as it facilitates the sheared sheet being pushed into the material-receiving sleeve 220 by the second pushing mechanism 320, and after being pushed in, it can effectively be stuck inside the material-receiving sleeve 220, while also facilitating the sheet being pushed out of the material-receiving sleeve 220 by the first pushing mechanism 310 to complete unloading. In this embodiment, the orifice structure of the material-receiving sleeve 220 is preferably an inward-retracting structure, that is, the diameter of the orifice end of the material-receiving sleeve 220 gradually decreases from the outside to the inside. Thus, as the sheet is pushed into the material-receiving sleeve 220, the inward squeezing force on the outer edge of the sheet increases, naturally bending and deforming to be stuck inside the material-receiving sleeve 220; and during unloading, it is only necessary to push the sheet out naturally, and the sheet, having lost the squeezing constraint of the inner hole of the material-receiving sleeve 220, naturally returns to its original shape.

[0068] Please continue reading Figures 3 to 8 In a preferred embodiment, the material handling device 300 further includes a second pushing mechanism 320. Specifically, the second pushing mechanism 320 includes a pressing telescopic power source 321 and a pressure plate 322. The pressing telescopic power source 321 is disposed within the inner hole of the material handling sleeve 220. The pressure plate 322 is disposed on the telescopic shaft of the pressing telescopic power source 321, and the pressing telescopic power source 321 can drive the pressure plate 322 to rise and fall perpendicularly to the machine base 240.

[0069] After punching is completed, the second pushing mechanism 320 and the first pushing mechanism 310 move simultaneously towards the sheet material to clamp the workpiece. Then, the second pushing mechanism 320 retracts while the first pushing mechanism 310 extends, pushing the workpiece further upwards into the take-up sleeve 220 through the punching hole 231. Alternatively, the first pushing mechanism 310 can extend upwards, pushing the second pushing mechanism 320 back while simultaneously pushing the workpiece into the take-up sleeve 220. After the workpiece is pushed into a suitable position within the take-up sleeve 220, the second pushing mechanism 320 releases pressure and remains in the retracted position. Subsequently, the telescopic shaft of the punching mechanism 210 and the first pushing mechanism 310 retract respectively. Based on the inherent stretchability of the flexible sheet, when the edge of the workpiece moves upward along the inner wall of the picking sleeve 220, it forms a downward bending deformation. After the first pushing mechanism 310 retracts, the sheet forms an upward arch with a certain elasticity and naturally gets stuck in the inner hole of the picking sleeve 220.

[0070] In use, the pressure plate 322 and support plate 312 can be driven to move by the pressure telescopic power source 321 and the loading telescopic power source 311, thereby driving the workpiece to move. It should be noted that, in specific implementations, both the pressure telescopic power source 321 and the loading telescopic power source 311 can be selected from other mechanisms that can achieve linear pressure, such as cylinders, hydraulic cylinders, and lead screws commonly used in the prior art.

[0071] As a preferred embodiment, in specific implementation, both the pressure plate 322 and the support plate 312 can be provided with vertically penetrating air holes to allow air to pass through the pressure plate 322 and the support plate 312, thereby eliminating the situation where the sheet is carried out by the force generated by the air flow when the pressure plate 322 and the support plate 312 move up and down.

[0072] The present invention also provides a method for taking material from a stamping part, which uses the above-mentioned stamping material taking device, and the specific steps include:

[0073] A flexible sheet-like workpiece with a length greater than the inner diameter of the take-up sleeve 220 in at least one direction is punched out by a punching and taking-up device.

[0074] After punching is completed, the workpiece is pushed into the inner hole of the take-up sleeve 220 by the first pusher mechanism 310, and the workpiece is stuck in the inner hole of the take-up sleeve 220 by the bending deformation of the workpiece.

[0075] This method allows for the temporary storage of punched workpieces within the inner hole of the take-up sleeve 220, which can then be removed when needed and at the desired location.

[0076] In addition, the present invention also provides a workstation transfer method, which adopts the above-mentioned stamping part material handling method and further includes:

[0077] The stamping device 200 has been moved to the next station by moving the moving mounting plate 410 driven by the moving drive source 420.

[0078] The workpiece, which is stuck in the inner hole of the take-up sleeve 220, is pushed out by the second pusher mechanism 320.

[0079] The working principle of the above-mentioned stamping material handling device, stamping part handling method and station transfer method is as follows:

[0080] While the strip 1 is being continuously wound and unwound, the stamping process can begin, specifically as follows:

[0081] First, in the initial state, the outer mold 234 is demolded from the inner mold 233, and the lower end face of the outer mold 234 separates from the upper end face of the inner mold 233 to form a feeding gap for the strip 1 to pass through. The strip 1 is then inserted between the inner mold 233 and the outer mold 234 (see...). Figure 1 );

[0082] Second, the stamping mechanism 210 starts and drives the material take-up sleeve 220 on it to move downward as a whole; the material take-up sleeve 220 presses the outer die 234 downward (see...). Figure 3 This allows the inner mold 233 to engage with the outer mold 234 for punching and shearing, and forces the elastic expansion member 2321 to contract (see...). Figure 4 );

[0083] 3. The pressing telescopic power source 321 extends downwards, and the loading telescopic power source 311 extends upwards, causing the pressing plate 322 and the support plate 312 to clamp the punched sheet material from the top and bottom (see...). Figure 5 );

[0084] 4. The loading telescopic power source 311 continues to extend upward, pushing the pressure plate 322 and the pressing telescopic power source 321 to retract (or the pressing telescopic power source 321 can retract automatically and synchronously), pushing the sheet into the material taking sleeve 220 (see...). Figure 6 );

[0085] Based on the flexible sheet's own stretching capacity, when it moves upward along the inner wall of the material picking sleeve 220 under the double-sided clamping, it forms a downward bending deformation at the edge. After the support plate 312 retracts, the sheet forms an upward arch with a certain elasticity and is naturally stuck inside the material picking sleeve 220.

[0086] 5. The stamping mechanism 210 retracts, and the loading telescopic power source 311 retracts (see...). Figure 7 ).

[0087] 6. The stamping mechanism 210 continues to retract until the take-up sleeve 220 disengages from the outer mold 234 (see...). Figure 8 ).

[0088] This cycle allows for the stamping, shearing, and gripping of flexible sheets. If it is necessary to further move the cut sheet workpiece to a lower station, the feeding mechanism 400 continues to operate, as follows:

[0089] First, the mobile drive source 420 drives the material picking sleeve 220 to move to the required workstation via the mobile mounting plate 410 (see 9).

[0090] Second, the telescopic shaft of the stamping mechanism 210 extends downward to deliver the material-taking sleeve 220 above the structure where the sheet material needs to be installed, so that it is close to the target structure or suspended above the target position (see...). Figure 10 );

[0091] 3. The pressing and telescopic power source 321 extends downward to push the sheet out and press it into the target position (see...). Figure 11 ).

[0092] And so it goes.

[0093] This device eliminates the need for additional material handling equipment, integrating punching, material handling, and material transfer into one unit. It avoids repetitive positioning, reduces production processes, improves material handling and assembly accuracy, and reduces production costs.
