Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and more specifically to an automatic feeding punching device. Background Technology

[0002] Currently, the punching of profiles, especially long and narrow workpieces such as aluminum and thin-walled steel profiles, still largely relies on traditional punch presses combined with manual feeding and positioning. Operators typically place the profile on the punch press table, visually position it using a ruler, simple stops, or scale lines, and then step on a foot switch or press a button to drive the punch press to complete the punching. For profiles requiring multi-hole processing or multi-process continuous processing, it is often necessary to repeatedly move and reposition the profile manually, making the operation cumbersome and the cycle time difficult to control uniformly.

[0003] Under the aforementioned processing mode, since positioning relies primarily on manual experience and visual inspection, it is difficult to maintain consistent feeding positions of the profiles along their length and postures along their width and vertical directions. Deviations often exist in the hole spacing between multiple holes and the relative positions of holes to the edges, making it difficult to guarantee product consistency and precision. While some companies have added simple limiting baffles or fixing fixtures to the worktable, these are typically only suitable for profiles of a single specification or with fixed hole positions. When changing product models or altering the hole arrangement, frequent adjustments or replacements of fixtures are required, resulting in long setup times and poor flexibility.

[0004] On the other hand, manual feeding and retrieval of materials require operators to repeatedly approach or even insert their hands into the mold area. With short punching cycles and fast production paces, this frequent human-machine interaction poses a high risk of pinching and crushing injuries. Even with photoelectric protection or protective covers on some equipment, the need to balance ease of operation often means that protective measures cannot completely cover all dangerous postures, leaving safety hazards unresolved. Furthermore, the lack of a unified transfer and transition mechanism between multiple processes means that punched profiles are typically manually handled or pushed to the next workstation or receiving area, resulting in high labor intensity.

[0005] Existing technologies also include some punching equipment with feeding mechanisms. By setting up a simple roller conveyor or a single-sided motor-driven pushing mechanism in front of the punch press, a certain degree of automatic feeding is achieved. However, the overall structure is still based on a single worktable. The functions of feeding, clamping, punching, and unloading are concentrated in the same area. The clamping constraints on the profile before and after entering the punching area are insufficient. There is a lack of supporting multi-point clamps and independent worktable support structures upstream and downstream of the punching area. The posture of the profile before and after punching is difficult to control stably, which makes it difficult to meet the requirements of long profiles, high-precision hole processing, and continuous automated production.

[0006] Therefore, based on existing technology, it is necessary to provide an automatic feeding and punching equipment with a reasonable structural layout and clear feeding path, which can coordinate multiple workstations during profile feeding, pre-punching positioning, punching process constraint, and post-punching conveying and collection. This will improve the accuracy, consistency and automation of profile punching processing, and reduce the labor intensity and safety risks of operators. Utility Model Content

[0007] The purpose of this utility model is to overcome the problems of low feeding and positioning accuracy, low degree of automation and insufficient safety in the existing technology, and to provide an automatic feeding and punching equipment. Through the arrangement of multiple workstations and the cooperation of multiple sets of clamps, the profile is clamped, fed, punched and discharged in sequence along a fixed path.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A second motor and a first lead screw are set on the second worktable. The power output shaft of the first motor is connected to the input shaft of the first lead screw. A slide is set on the first lead screw, and a first connector, a first clamp and a first cylinder are set on the slide in sequence.

[0012] A second clamp is installed inside the fixed platform, and a connector is installed at the upper end of the second clamp. Third clamps are installed on both sides of the fixed platform, and each third clamp is connected to the second cylinder through a second connector.

[0013] A stamping cylinder is installed above the fixed platform, and the output end of the stamping cylinder is connected to the punching assembly;

[0020] Preferably, each second cylinder is connected to a corresponding third clamp via a second connector, and the second cylinder is fixedly installed relative to the fixed platform.

[0021] Preferably, the stamping cylinder and the punching assembly are arranged vertically, with the punching assembly located between the second and third clamps above the fixed platform.

[0023] Preferably, an electrical connection is provided between the central control panel and the first motor, the second motor, the first cylinder, the second cylinder, and the stamping cylinder.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0036] Example

[0037] like Figures 1 to 4 As shown, an automatic feeding punching device according to this embodiment includes a frame 1. The frame 1 adopts a steel structure frame form, and a first worktable 101, a fixed table 3, and a second worktable 102 are sequentially installed on the upper end face of the frame 1 along the same straight line, so that the first worktable 101, the fixed table 3, and the second worktable 102 form a continuous processing path in space.

[0038] A first motor 2 and a first lead screw 201 are mounted on a first worktable 101. The first lead screw 201 is arranged along the length of the first worktable 101. The first motor 2 is fixedly mounted at the end or side of the first worktable 101. The power output shaft of the first motor 2 is connected to the input shaft of the first lead screw 201 by a coupling. A slide 203 is mounted on the first lead screw 201 by a threaded engagement. The slide 203 can reciprocate along the length of the first worktable 101. A first connecting member 204, a first clamp 205, and a first cylinder 206 are sequentially fixed to the upper surface of the slide 203. The first connecting member 204 is rigidly connected to the slide 203. The first clamp 205 is mounted above the first connecting member 204. The first cylinder 206 is fixed to the first connecting member 204 by a connecting structure. The piston rod end of the first cylinder 206 is connected to the first clamp 205, so that the first cylinder 206 drives the first clamp 205 to perform clamping or releasing actions. The first motor 2 drives the first lead screw 201 to rotate, and the slide 203 moves along the direction of the first worktable 101, cooperating with the first clamp 205 to clamp and transport the profile.

[0039] The structure of the second worktable 102 is basically the same as that of the first worktable 101. A second motor 202 and another first lead screw 201 are installed on the second worktable 102. The first lead screw 201 is arranged along the length of the second worktable 102. The second motor 202 is fixedly installed at the end or side of the second worktable 102, and its power output shaft is connected to the input shaft of the corresponding first lead screw 201. A slide 203 is also installed on the first lead screw 201, which moves along the length of the second worktable 102. A first connecting member 204 and a first clamp 205 are sequentially fixed to the upper surface of the slide 203 on the second worktable 102, and a first cylinder 206 is installed. The first connecting member 204 is fixedly connected to the slide 203. The first clamp 205 is located on the upper part of the first connecting member 204, and the first cylinder 206 is connected to the first connecting member 204. The piston rod end of the first cylinder 206 is connected to the first clamp 205. When the second motor 202 drives the corresponding first lead screw 201 to rotate, the slide 203 moves along the direction of the second worktable 102, and cooperates with the first clamp 205 to clamp and transport the profile that has completed the punching process.

[0040] A fixed platform 3 is positioned between the first worktable 101 and the second worktable 102, and is fixed relative to the frame 1. A second clamp 301 is installed inside the fixed platform 3, arranged along the width or length direction of the fixed platform 3, and connected to the fixed platform 3 via an internal mounting structure. A connector 302 is provided at the upper end of the second clamp 301, which is connected to an external power output device, allowing the second clamp 301 to clamp or release the profile on the fixed platform 3 when needed.

The second cylinder 401 is fixedly installed relative to the frame 1 or the fixed platform 3. The output end of the second cylinder 401 is fixedly connected to the third clamp 4 via the second connector 402. When the second cylinder 401 extends or retracts, it drives the third clamp 4 to move in a predetermined direction, so that the third clamps 4 on both sides of the fixed platform 3 can move closer to or further away from the fixed platform 3, forming lateral or local clamping constraints on the profile. The third clamps 4 on both sides are symmetrically arranged along the profile conveying direction, so that the profile in the area of ​​the fixed platform 3 can obtain multi-point, symmetrical clamping support before punching.

[0042] like Figure 3 and Figure 4 As shown, a stamping cylinder 5 is installed above the fixed platform 3. The stamping cylinder 5 is fixed to the frame 1 or the fixed platform 3 by a mounting bracket, and the output end of the stamping cylinder 5 is connected to the punching assembly 501. The punching assembly 501 is arranged vertically above the fixed platform 3. The second clamp 301 is arranged vertically corresponding to the punching assembly 501. When the second clamp 301 clamps the profile, the area to be processed on the profile is located directly below the punching assembly 501. The stamping cylinder 5 drives the punching assembly 501 to reciprocate vertically to perform punching processing on the profile. The third clamp 4, driven by the second cylinder 401, clamps both sides of the profile to maintain a stable posture during the punching process.

[0043] A discharge bin 6 is provided on one side of the frame 1, located at the end of the fixed platform 3 away from the first worktable 101. After the profile completes the punching process in the area of ​​the fixed platform 3, the slide 203 and the first clamp 205 on the second worktable 102 clamp the profile and, driven by the second motor 202, transport the profile to the discharge bin 6 area, so that the punched profile is stacked in a concentrated manner.

[0044] A central control console 7 is mounted on the frame 1, and control buttons 8 are installed on the central control console 7. The central control console 7 is electrically connected to the first motor 2, the second motor 202, the first cylinder 206, the second cylinder 401, and the stamping cylinder 5 via cables, allowing centralized control of the start / stop, action sequence, and working status of the above components. The control buttons 8 are used to input start, stop, and emergency stop commands, facilitating operation and management of the equipment by the operator.

[0045] In this embodiment, the lengths of the first workbench 101, the fixed table 3, and the second workbench 102 can be selected according to the length of the profile being processed. The specific structural forms of the first clamp 205 and the second clamp 301 can be mechanical clamping structures or other conventional clamping structures. The jaw shape of the third clamp 4 can be set according to the cross-sectional shape of the profile. The punching assembly 501 can use a single-station punch or a combination of multi-station punches according to the required hole diameter and hole type. Any adjustments made by those skilled in the art to the arrangement dimensions, materials, and driving methods of the components without changing the above structural relationships are within the protection scope of this utility model.

[0046] The structure corresponding to this embodiment is consistent with each of the claims in the aforementioned claims. Through the above specific structural arrangement, the profile is initially clamped and fed on the first workbench 101, clamped and punched on the fixed table 3, and then conveyed and discharged on the second workbench 102, thereby forming an automatic feeding and punching processing path that is continuously arranged along the direction of the frame 1.
