In the stamping machine, the press provides sufficient pressure on the workpiece, and at the same time, the punch and die of the mold interact with each other during the pressing process, so that the metal sheet set between them is punched, bent, stretched, etc. according to a predetermined shape. During the processing, the connecting bracket only bends the steel plate and forms a suitable shape. By setting a die with a corresponding shape, the shape of the steel plate and the die are matched during the stamping process to form a specific structure.

[0013] The present application also provides a connection bracket forming mechanism, comprising the following steps: S1, a feeding structure slides along a sliding frame so that a feeding plate of the feeding structure moves to a positioning device;

[0014] S2. Position the feeding plate of the feeding structure so that the buffer on the feeding structure matches the positioning column on the positioning plate, and record the current position of the feeding plate as the starting position, and place the material to be processed on the material storage rack;

[0015] S3, conduct a trial run to make the buffer of the feeding structure match the positioning protrusions of the placing mechanism, the positioning mechanism and the punching mechanism respectively;

[0016] S4, start running, the feeding structure grabs the material at the material storage rack and moves it to the material placement mechanism, places the material on the material placement mechanism, and the rotating disk of the material placement mechanism drives the material placement plate to rotate so that the direction of the material in the material placement plate matches the shape of the embedded groove. After the adjustment is completed, the feeding structure grabs the material again;

[0017] S5, the feeding mechanism continues to move, at this time, the material grabbed by the first-order feeding structure is moved to the positioning mechanism through the moving frame and the material is placed, and the second-order feeding structure moves to the placement mechanism and clamps the material;

[0018] S6. Adjust the position of the material at the positioning mechanism so that the material can completely fit into the embedded groove on the positioning mechanism;

[0019] S7, the feeding mechanism continues to move, at this time, the material grabbed by the first-order feeding structure is moved to the stamping mechanism through the moving frame, the second-order feeding structure is moved to the positioning mechanism, and the third-order feeding structure is moved to the placing mechanism and clamps the material;

[0020] S8, the punching mechanism punches the material on the forming groove, so that the material on the forming groove is pushed into the inside of the forming groove, and the part of the material arranged outside the forming groove conflicts with the punching base, and the squeezing block pushes the material to fix it, and the pressing block keeps squeezing the material for T time;

[0021] S9, after the T time period, the extrusion block withdraws, and at the same time the feeding structure grabs the stamped workpiece and puts it into the discharge rack to complete the discharge;

[0022] S10, the feeding mechanism continues to move so that the feeding structure at the second position matches the position of the punching mechanism, the material on the feeding structure at the second position is placed in the punching mechanism for punching, and after the punching is completed, the workpiece is placed in the discharge rack to complete the discharge;

[0023] S11, the feeding mechanism continues to move, so that the feeding structure at the third position matches the position of the punching mechanism, the material on the feeding structure at the third position is placed in the punching mechanism for punching, and after the punching is completed, the workpiece is placed in the discharge rack to complete the discharge;

[0024] S12, the feeding mechanism continues to move, and at the same time, the sensing device on the stamping mechanism detects whether there is a workpiece at its front end. If the infrared sensor does not detect the existence of a workpiece at its front end, it is determined that the processing of the workpiece on the current feeding mechanism is completed, and there is no workpiece in the current feeding mechanism. The feeding mechanism returns to the starting position and jumps back to S4 for processing again. Otherwise, it continues to move and process.

[0025] By adopting the above technical scheme, the beneficial effects are as follows: 1. By arranging a feeding structure and a processing structure matching the feeding structure in the device, the processing mechanism includes a placing mechanism, a positioning mechanism and a stamping mechanism. The feeding structure drives the workpiece to flow between various stations, realizing the loading, positioning, stamping and unloading of the workpiece, and the movement of the workpiece between the stations is realized by the sliding of the feeding plate on the sliding frame. The degree of automation is high and the processing effect is good. At the same time, the steel plate can be positioned and fixed during the stamping process to prevent deviation during stamping, thereby ensuring the qualified rate of the finished product and improving the use effect.

[0026] 2. Furthermore, in order to position the workpiece before processing and thus facilitate subsequent processing, a material placing plate is provided on the top of the material placing mechanism, and a limiting rod is provided on the material placing plate. The limiting rods are spaced apart to form a space for placing the workpiece, and the workpiece can interfere with the limiting rod after being placed, thereby avoiding the movement of the workpiece on the material placing plate and ensuring that when the feeding structure grabs the workpiece, the orientation angle of the workpiece is consistent with the grabbing position, without the need for additional angle adjustment, the adjustment effect is good, and the processing efficiency is high.

[0027] 3. At the same time, in order to facilitate the processing of the workpiece, the specific position of the workpiece needs to be adjusted before the workpiece is stamped. Generally speaking, before the workpiece is stamped, the workpiece needs to be matched with the molding groove of the stamping base. Specifically, the formed workpiece has a base part and a bent part. The base part is pushed into the molding groove by the pressing block during the extrusion process, and the bent part is the part that is relatively located outside the molding groove when the workpiece is placed on the molding groove. When the workpiece is extruded, the bent part and the stamping base collide with each other, so that the edge of the workpiece is tilted and a bent part is formed. Due to the high requirements on the processing accuracy of the workpiece, the workpiece needs to be placed in a precise position and processed to facilitate the forming of the workpiece. Specifically, before the workpiece is stamped, the workpiece needs to be placed in the embedded groove to limit the direction and position of the workpiece. Specifically, since the feeding structure moves parallel to the device, the position of the workpiece will not change too much after being placed on the stamping mechanism, the processing effect is good, and the qualified rate of the finished product is high.

[0028] 4. Furthermore, in the process of stamping the workpiece, in order to ensure the continuity of the processing process, the device has a storage part and a processing part. Specifically, the material to be processed is arranged in the storage part and stacked in the storage part. During processing, the feeding mechanism grabs the material from the material storage rack and moves it to the placing mechanism. The placing mechanism rotates the placing plate so that the direction of the material in the placing plate is basically the same as the direction of the embedded groove. At the same time, since there are multiple feeding mechanisms, when the first-order feeding mechanism is located at the placing mechanism, the second-order feeding mechanism is located at the material storage rack and grabs the material. Subsequently, the feeding mechanism continues to move. At this time, the first-order feeding mechanism moves to the positioning mechanism and puts down the material. The material is limited by the embedded groove of the positioning mechanism, so that the position of the material is accurately adjusted, and the adjustment effect is good. At this time, the second-order feeding mechanism The feeding mechanism is located at the placing mechanism, and the placing mechanism adjusts the material grabbed by the second-order feeding mechanism. At the same time, the third-order feeding mechanism is located at the material storage rack and grabs the material. When the first-order feeding mechanism is located at the stamping mechanism and performs stamping operations on the workpiece, the second-order feeding mechanism is located at the positioning mechanism and makes detailed adjustments to the position of the workpiece. The third-order feeding mechanism is located at the placing mechanism and discharges the finished product after processing. The above method is used for cyclic processing, and the processing continuity is good. The workpiece is squeezed and fixed during the processing, which further improves the overall processing stability and processing accuracy. At the same time, the stamping mechanism is also provided with a sensing device, which can detect whether there is still a workpiece on the feeding mechanism, and choose to continue processing or return to the starting position according to the detected structure, and the degree of automation is high.

Specifically, the formed workpiece has a base part and a bent part. The base part is pushed into the molding groove 82 by the pressing block 43 during the extrusion process, and the bent part is the part that is relatively located outside the molding groove 82 when the workpiece is placed on the molding groove 82. When the workpiece is extruded, the bent part and the stamping base 81 collide with each other, so that the edge of the workpiece is tilted and a bent part is formed. Due to the high processing accuracy requirements for the workpiece, the workpiece needs to be placed in a precise position and processed to facilitate the forming of the workpiece.

Position the feeding plate of the feeding structure so that the buffer on the feeding structure matches the positioning column on the positioning plate, and record the current position of the feeding plate as the starting position, and place the material to be processed on the material storage rack; S3, conduct a trial run to make the buffer of the feeding structure match the positioning protrusions of the placing mechanism, the positioning mechanism and the punching mechanism respectively; S4, start running, the feeding structure grabs the material on the material storage rack and moves it to the material placement mechanism, places the material on the material placement mechanism, and the rotating disk of the material placement mechanism drives the material placement plate to rotate so that the direction of the material in the material placement plate matches the shape of the embedded groove. After the adjustment is completed, the feeding structure grabs the material again; S5, the feeding mechanism continues to move, at this time, the material grabbed by the first-order feeding structure is moved to the positioning mechanism through the moving frame and the material is placed, and the second-order feeding structure moves to the placement mechanism and clamps the material; S6. Adjust the position of the material at the positioning mechanism so that the material can completely fit into the embedded groove on the positioning mechanism; S7, the feeding mechanism continues to move, at this time, the material grabbed by the first-order feeding structure is moved to the stamping mechanism through the moving frame, the second-order feeding structure is moved to the positioning mechanism, and the third-order feeding structure is moved to the placing mechanism and clamps the material; S8, the punching mechanism punches the material on the forming groove, so that the material on the forming groove is pushed into the inside of the forming groove, and the part of the material arranged outside the forming groove conflicts with the punching base, and the squeezing block pushes the material to fix it, and the pressing block keeps squeezing the material for T time; S9, after the T time period, the extrusion block withdraws, and at the same time the feeding structure grabs the stamped workpiece and puts it into the discharge rack to complete the discharge; S10, the feeding mechanism continues to move so that the feeding structure at the second position matches the position of the punching mechanism, the material on the feeding structure at the second position is placed in the punching mechanism for punching, and after the punching is completed, the workpiece is placed in the discharge rack to complete the discharge; S11, the feeding mechanism continues to move, so that the feeding structure at the third position matches the position of the punching mechanism, the material on the feeding structure at the third position is placed in the punching mechanism for punching, and after the punching is completed, the workpiece is placed in the discharge rack to complete the discharge; S12, the feeding mechanism continues to move, and at the same time, the sensing device on the stamping mechanism detects whether there is a workpiece at its front end. If the infrared sensor does not detect the existence of a workpiece at its front end, it is determined that the processing of the workpiece on the current feeding mechanism is completed, and there is no workpiece in the current feeding mechanism. The feeding mechanism returns to the starting position and jumps back to S4 for processing again. Otherwise, it continues to move and process.
