Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a bracket sheet metal positioning and cutting device. Background Technology

[0002] In sheet metal processing, precise cutting of sheet metal materials of specific shapes, such as brackets, is a fundamental and crucial process. To ensure the dimensional accuracy and quality of the final product, the sheet metal bracket to be processed must be stably and accurately placed in the predetermined position on the cutting equipment before cutting.

[0003] Currently, in many machining scenarios, the positioning of bracket sheet metal mainly relies on manual operation. Operators need to place the bracket sheet metal on a workbench and visually align its edges or center line with reference lines or simple mechanical stops marked on the equipment. This process depends entirely on the operator's experience and sense of responsibility.

[0004] However, this purely manual positioning method has significant drawbacks. First, visual alignment inevitably introduces errors; operator fatigue or momentary lapses can cause positioning misalignment, preventing the bracket sheet metal from being precisely centered. This directly affects subsequent cutting accuracy, resulting in inconsistent finished product dimensions and a lower product yield. Second, the repeated manual alignment adjustments are time-consuming and cumbersome, significantly reducing overall production efficiency and making it difficult to meet the demands of modern, fast-paced production.

[0005] Therefore, this utility model proposes a bracket sheet metal positioning and cutting device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a bracket sheet metal positioning and cutting device, which aims to improve the problems of existing technologies that rely on manual alignment, have low positioning accuracy and efficiency, and are cumbersome to operate.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bracket sheet metal positioning and cutting device, including a cutter and a positioning component, the positioning component being disposed on the feed side of the cutter, the positioning component including a center block, the center block being used to support the bracket sheet metal; The central block has a rotating turntable inside. The positioning component also includes two symmetrically arranged contraction bars and two symmetrically arranged swing bars. The two contraction bars are slidably arranged inside the central block, and the top of the contraction bars extends out of the top surface of the central block. One end of each swing bar is hinged to the edge of the turntable, and the other end of the swing bar is hinged to the bottom end of the corresponding contraction bar. Through the combination of the central block, turntable, contraction bars and swing bars, the automatic centering and positioning of the bracket sheet metal is realized. Preferably, the positioning component further includes a pull handle, which extends from the side wall of the central block and is fixedly connected to the turntable; Preferably, the positioning component further includes multiple support bars, which are arranged in parallel and fixed above the central block, and each support bar has a sliding tube rotatably sleeved on its outer wall; Preferably, it also includes a discharge conveying pipe and a fixing component, wherein the discharge conveying pipe is disposed on the discharge side of the cutter and the fixing component is disposed at the end of the discharge conveying pipe; Preferably, the fixing component includes a support column vertically fixed to the discharge conveyor pipe, and a baffle slidably disposed on the support column; Preferably, a sliding column is fixedly connected to the back of the baffle, and the fixing assembly also includes an outer wall block and a support ring. The outer wall block and the support ring are fixed to the support column at intervals, and the sliding column slides through the outer wall block and the support ring. Preferably, an outer wall ring is fixed on the outer wall of the sliding column, and the fixing assembly also includes an elastic element, which is sleeved on the sliding column; Preferably, the two ends of the elastic element abut against the top surface of the outer wall ring and the bottom surface of the outer wall block, respectively.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problems of manual alignment, cumbersome operation, low efficiency and unstable positioning accuracy in the existing technology when positioning bracket sheet metal by setting up a synchronous centering mechanism composed of a pull handle, turntable, swing bar and shrink bar.

It achieves the effect of using the lifting force of the sheet metal itself to trigger the pressing action and automatically pressing the sheet metal after cutting, thus ensuring cutting stability and improving safety.

[0010] 3. This utility model solves the problem of high friction and laborious operation when pushing the sheet metal of the support bracket into the material by rotating and sleeved sliding tube on the support strip of the support bracket sheet metal. It achieves the effect of changing sliding friction into rolling friction, greatly reducing the feeding resistance and making the operation more labor-saving and convenient.

Detailed Implementation

[0013] 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.

[0014] Reference Figures 1-5 This utility model provides an embodiment of a bracket sheet metal positioning and cutting device, including a cutter 1 and a positioning component 2 disposed on the feed side of the cutter 1. The cutter 1 is used to cut the bracket sheet metal, and the positioning component 2 is used to achieve precise centering positioning of the bracket sheet metal. The positioning component 2 includes a center block 202, which is used to support the bracket sheet metal. A turntable 205 is rotatably disposed inside the center block 202. The positioning component 2 also includes two symmetrically arranged shrink strips 207 and two symmetrically arranged swing strips 206. All shrink bars 207 are slidably disposed within the center block 202, and the top of each shrink bar 207 extends out of the top surface of the center block 202. One end of each swing bar 206 is hinged to the edge of the turntable 205, and the other end of each swing bar 206 is hinged to the bottom of the corresponding shrink bar 207. This structure, through the coordinated action of the turntable 205, the two swing bars 206, and the two shrink bars 207, converts the rotational motion of the turntable 205 into the sliding of the two shrink bars 207 towards or away from each other, thereby achieving automatic centering and positioning of the bracket sheet metal. The central block 202 serves as the main structural frame of the positioning assembly 2 and contains a rotating mechanism. The turntable 205 is rotatably mounted inside the central block 202. The positioning assembly 2 also includes two symmetrically arranged contraction bars 207 and two symmetrically arranged swing bars 206. Both contraction bars 207 are slidably mounted inside the central block 202, with their top ends extending beyond the top surface of the central block 202 for contact with the bracket sheet metal. One end of each swing bar 206 is hinged to the edge of the turntable 205, and the other end is hinged to the bottom end of the corresponding contraction bar 207. When an external force drives the turntable 205 to rotate, the rotational motion of the turntable 205 is transmitted to the swing bar 206 through the hinge point on the edge of the turntable 205, causing the swing bar 206 to swing. The swinging motion of the swing bar 206 further drives the contraction bar 207, which is hinged to its other end, to slide inside the center block 202. Since the two contraction bars 207 are connected to the same turntable 205 through their respective swing bars 206 and are arranged symmetrically, the rotation of the turntable 205 ensures that the two contraction bars 207 can slide towards or away from each other synchronously. This linkage mechanism ensures that the synchronous clamping of both sides of the bracket sheet metal is maintained when the contraction bars 207 slide, thereby achieving precise centering positioning of the bracket sheet metal. In a preferred embodiment, in order to facilitate the rotation of the turntable 205, the positioning component 2 also includes a handle 203. The handle 203 extends from the side wall of the central block 202 and is fixedly connected to the turntable 205. By pulling or pushing the handle 203, the turntable 205 can be directly rotated, thereby driving the entire positioning mechanism to move. As another preferred embodiment, in order to reduce the friction of the bracket sheet metal during the pushing process, the positioning component 2 also includes multiple support bars 204. The support bars 204 are arranged in parallel and fixed above the center block 202 to provide support for the bracket sheet metal. Each support bar 204 has a sliding tube 201 rotatably sleeved on its outer wall. The sliding tube 201 acts as a roller and can rotate freely when the bracket sheet metal is pushed, thereby significantly reducing the feeding resistance. In another preferred embodiment, in order to press and fix the bracket sheet metal after cutting, the bracket sheet metal positioning and cutting device also includes a discharge transport pipe 3 and a fixing component 4. The discharge transport pipe 3 is located on the discharge side of the cutter 1 and is used to receive and transport the cut sheet metal. The fixing component 4 is located at the end of the discharge transport pipe 3. Specifically, the fixing component 4 includes a support column 402 vertically fixed to the discharge conveying pipe 3, and a baffle 401 slidably disposed on the support column 402. A sliding column 406 is fixedly connected to the back of the baffle 401. In order to provide guidance and limit for the sliding of the sliding column 406, the fixing component 4 also includes an outer wall block 403 and a support ring 405. The outer wall block 403 and the support ring 405 are fixed to the support column 402 at intervals. The sliding column 406 slides through the outer wall block 403 and the support ring 405. In order to realize the automatic reset of the baffle 401, an outer wall ring 407 is fixed on the outer wall of the sliding column 406. The fixing component 4 also includes an elastic element 404. The elastic element 404 is sleeved on the sliding column 406, and the two ends of the elastic element 404 abut against the top surface of the outer wall ring 407 and the bottom surface of the outer wall block 403, respectively.

[0015] Working principle: During positioning, the bracket sheet metal is first placed on the surface of the sliding tube 201 above the positioning component 2. Then, by pulling the handle 203, the handle 203 drives the turntable 205 to rotate inside the center block 202. The rotation of the turntable 205 drives the two shrinking strips 207 to slide towards each other inside the center block 202 through the two swing bars 206. Finally, the top of the shrinking strips 207 clamps from both sides of the bracket sheet metal to achieve automatic centering positioning. After positioning is completed, the bracket sheet metal is pushed towards the cutter 1. The sliding tube 201 below the bracket sheet metal rotates on the support bar 204, reducing the feeding thrust. When cutting and pressing, when the bracket sheet metal is pushed into the cutter 1 and cutting is started, the sheet metal at one end of the discharge transport pipe 3 will tilt upward and push up the baffle 401. The baffle 401 slides upward along the support column 402, and at the same time drives the sliding column 406 fixed on the back of the baffle 401 to slide upward. The outer wall ring 407 on the sliding column 406 will compress the elastic element 404 upward. When the cutting action is completed, under the action of the elastic force of the elastic element 404, the elastic element 404 pushes the outer wall ring 407, thereby driving the sliding column 406 and the baffle 401 to quickly return to their original position. The returned baffle 401 presses the cut bracket sheet metal back onto the surface of the discharge transport pipe 3.
