Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to a method and an automatic device for processing the inner circle of a square flange. Background Art

[0002] ‌Flange end plate‌ is a connecting component used for flange ends, usually made of square steel plates with an inner circle hole in the middle for easy connection with other components. During the manufacturing process of flange end plates, a series of processing techniques such as stamping, grinding, and cutting are required, and the inner circle of the flange is obtained by stamping.

[0003] In existing stamping equipment, production lines usually use the method of feeding at equal intervals to achieve continuous stamping, that is, the intervals between each feeding are the same, so that the stamping mechanism only needs to perform simple reciprocating stamping to complete periodic production. However, for larger parts such as end plates or parts with complex processes, it is difficult to feed materials at equal intervals each time due to the different production and processing procedures of the parts, so the method of feeding materials at equal intervals is not applicable. Therefore, how to achieve coordinated operation between stamping equipment and other equipment is an urgent problem to be solved. Summary of the invention

[0004] The purpose of the present application is to provide a method and an automatic device for processing the inner circle of a square flange.

[0005] In order to achieve the above purpose, the technical solution adopted in the present application is: an automatic device for processing the inner circle of a square flange, which is used to clamp and transfer the material when the material is stamped, including an electronic control system, a conveying mechanism and a stamping mechanism. A stamping station is provided in the middle of the conveying mechanism, and the stamping mechanism is arranged on the stamping station. A loading mechanism is provided above the conveying mechanism, and one loading mechanism is provided on both sides of the stamping mechanism, respectively. The loading mechanism on the inlet side is suitable for clamping the material from one side of the conveying mechanism to the stamping mechanism, and the loading mechanism on the outlet side is suitable for clamping the material from the stamping mechanism to the other side of the conveying mechanism after the stamping is completed; a positioning component is provided on the outside of the stamping mechanism, and an induction component is provided between the positioning component and the loading mechanism. When the loading mechanism on the inlet side runs to its maximum stroke, the induction component is automatically triggered so that the positioning component pushes the material to the stamping position.

[0006] Preferably, the positioning component includes a fixed limiting portion arranged on the front side of the stamping mechanism and a pushing portion arranged at the rear of the stamping mechanism. When the loading mechanism transfers the material to the stamping station, the sensing component triggers the electronic control system so that the pushing portion pushes the material and abuts against the fixed limiting portion to position the material.

[0007] Preferably, the sensing component includes an elastic member and a pressure sensor arranged on the feeding mechanism. When the feeding mechanism clamps the material, the elastic member is elastically compressed. When the feeding mechanism releases the material, the elastic member is reset. The pressure sensor identifies the pressure change and starts the pushing part through the electronic control system.

[0008] Preferably, the elastic member comprises a trigger rod and a spring. When the material is clamped, the trigger rod moves to avoid or contracts and the spring contracts. When the material is released, the spring and the trigger rod are reset. The pressure sensor is connected to the spring.

[0009] As a preference, the feeding mechanism comprises a transverse moving assembly, a lifting assembly and a feeding portion, the lifting assembly is entirely arranged on the transverse moving assembly, and the feeding portion is arranged on the lifting assembly.

[0010] As a preference, the loading part is configured as an electromagnet or a vacuum suction cup, and when the loading part is close to the workpiece, it directly absorbs the workpiece, compressing the elastic part in the process, until the loading part and the workpiece arrive above the stamping mechanism, the loading part releases the workpiece, and the elastic part resets to trigger the pressure sensor recognition.

[0011] As a preferred embodiment, the loading part is configured as an electric clamping plate. When the loading part is close to the workpiece, it is first driven to descend by the lifting assembly. During the descent, the elastic part is compressed. When the electric clamping plate and the workpiece correspond, they are electrically clamped until the loading part and the workpiece arrive above the stamping mechanism, the electric clamping plate releases the workpiece and the lifting assembly is reset, and the elastic part is reset to trigger the pressure sensor recognition.

[0012] As a preference, a fixed frame is fixedly installed above the conveying mechanism, and the transverse movement assembly includes a guide rail, and the guide rail is fixedly installed on the fixed frame.

[0013] As a preference, the lifting assembly and the lateral movement assembly are both configured as cylinders.

[0014] On the other hand, the present application provides a square flange inner circle machining method, which comprises the above-mentioned inner circle machining automatic device, and further comprises the following steps: a. Pre-processing of materials: square materials are processed by laser cutting and the materials are transferred to the conveying mechanism.

[0015] b. Material loading: The square material is transferred to the inlet side of the stamping mechanism by the conveying mechanism, then loaded by the loading mechanism, and positioned by the positioning assembly.

[0016] c. Material positioning: The positioning component starts to start when the material leaves the feeding mechanism and positions the material on the stamping station of the stamping mechanism, and then the positioning component is reset.

[0017] d. Punching of materials: The punching mechanism punches out the materials to produce a suitable inner circle.

[0018] e. Post-processing of materials: The materials with inner circles punched out are transferred to the grinding station, where the grinding station performs grinding on the periphery of the inner circle.

[0019] Compared with the prior art, the beneficial effects of this application are: By setting up the induction component, the induction component can achieve a stable and accurate coordination effect when the feeding mechanism, the positioning component and the stamping mechanism are used together through mechanical triggering conditions.

[0034] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions.

[0035] Example: Reference Figures 1 to 8As shown, an automatic device for processing the inner circle of a square flange is used to clamp and transfer the material 13 when the material 13 is stamped, and includes an electric control system, a conveying mechanism 1 and a stamping mechanism 5. A stamping station is provided in the middle of the conveying mechanism 1, and the stamping mechanism 5 is arranged on the stamping station. A feeding mechanism is provided above the conveying mechanism 1, and one feeding mechanism is provided on both sides of the stamping mechanism 5. The feeding mechanism on the inlet side is suitable for clamping the material 13 from one side of the conveying mechanism 1 to the stamping mechanism 5. After the stamping is completed, the feeding mechanism on the outlet side is suitable for clamping the material 13 from the stamping mechanism 5 to the other side of the conveying mechanism 1; a positioning component is provided on the outside of the stamping mechanism 5, and an induction component is provided between the positioning component and the feeding mechanism. When the feeding mechanism on the inlet side runs to its maximum stroke, the induction component is automatically triggered so that the positioning component pushes the material 13 to the stamping position. During stamping, the hydraulic component 9 drives the punch 11 to move up and down, and the material 13 is placed on the base 12. Unless otherwise specified, all electrical components in this application can be connected to the electronic control system.

[0036] By setting the sensing component, when the material 13 reaches the appropriate position, the positioning component can be automatically triggered to position the material 13 to the appropriate position for stamping. In the existing stamping equipment, the production line type production usually adopts the method of equal-interval feeding to achieve continuous stamping, that is, the interval of each feeding is the same, so that the stamping mechanism 5 only needs to perform simple reciprocating stamping to complete the periodic production. However, in the case of larger parts such as the end plate in this embodiment or some parts with complex processes, it is difficult to achieve equal-interval feeding every time due to the different production and processing procedures of the parts, so the equal-interval feeding is not applicable. In this embodiment, the sensing component is set, and the sensing component is triggered by a mechanical condition, so that when the feeding mechanism, the positioning component and the stamping mechanism 5 are used together, a stable and accurate coordination effect can be achieved. For example, the use of a visual camera can also achieve the combined use of the three, but its stability and accuracy are not as good as the mechanical trigger. Of course, the sensing component of the present application actually needs to be operated by means of electronic control in the future, but it has good accuracy and stability in the key issue of how to identify the material 13 in the appropriate position and automatically position the positioning component.

[0037] like Fig. 9 As shown, in this embodiment, the positioning assembly includes a fixed limiting portion arranged on the front side of the stamping mechanism 5 and a pushing portion arranged at the rear of the stamping mechanism 5. When the feeding mechanism transfers the material 13 to the stamping station, the sensing assembly triggers the electric control system so that the pushing portion pushes the material 13 and abuts against the fixed limiting portion to position the material 13. The fixed limiting portion can refer to Fig.10, which is configured as a plurality of positioning rollers that conform to the contour of the material 13. When the material pushing portion pushes the material 13, the material 13 is positioned after being fully pushed into these positioning rollers.

[0038] The sensing component includes an elastic member and a pressure sensor arranged on the feeding mechanism. When the feeding mechanism clamps the material 13, the elastic member is elastically compressed. When the feeding mechanism releases the material 13, the elastic member resets, the pressure sensor recognizes the pressure change, and starts the pushing part through the electronic control system.

[0039] Preferably, the elastic member includes a trigger rod and a spring. When the material 13 is clamped, the trigger rod moves to avoid or shrinks, and the spring shrinks. When the material 13 is released, the spring and the trigger rod are reset; the pressure sensor is connected to the spring. The pressure sensor can easily cooperate with the spring to identify the corresponding pressure induction. Obviously, in the initial state, the spring is also in a relaxed state. Therefore, in this application, the pressure sensor is specifically required to sense the process of first pressurizing and then releasing. This process is used as a signal to enable the electronic control system to drive the positioning component to operate. Of course, these functions can be easily realized using components such as PLC, so the logic of the electronic control will not be further described.

[0040] like Figures 4 to 8 The feeding mechanism includes a transverse moving component 3, a lifting component 4 and a feeding part. The lifting component 4 is integrally arranged on the transverse moving component 3, and the feeding part is arranged on the lifting component 4. Figures 5 to 8 The following are several state diagrams of the feeding mechanism when feeding. Two specific implementation plans of the feeding part are proposed below.

[0041] The feeding part is set as an electromagnet or a vacuum suction cup. When the feeding part is close to the material 13, the material 13 is directly sucked, and the elastic part is compressed in the process until the feeding part and the material 13 reach the top of the stamping mechanism 5. The feeding part releases the material 13, and the elastic part is reset to trigger the pressure sensor recognition. Of course, the material 13 of the present application is an end plate, which is usually made of metal. When the weight is large, the suction force of the vacuum suction cup may be difficult to achieve, so it can be selected according to actual needs.

[0042] The feeding part is set as an electric clamping plate. When the feeding part is close to the material 13, it is first driven to descend by the lifting assembly 4. During the descent, the elastic member is compressed. When the electric clamping plate and the material 13 correspond, they are electrically clamped until the feeding part and the material 13 reach the top of the stamping mechanism 5. The electric clamping plate releases the material 13 and the lifting assembly 4 is reset. The elastic member is reset to trigger the pressure sensor recognition. In this embodiment, the electric clamping plate is two clamping plates that can approach each other and work in principle. Its principle is relatively simple, and this application only briefly describes its principle.

[0043] like Figure 1As shown, a fixed frame 8 is fixedly installed above the conveying mechanism 1, and the lateral movement assembly 3 includes a guide rail 7, which is fixedly installed on the fixed frame 8. The lifting assembly 4 and the lateral movement assembly 3 are preferably configured as cylinders. The cylinder can be extended and retracted to complete the lateral movement and lifting operations, and its principle is easy to understand, so it is not described in detail.

[0044] On the other hand, the present application provides a square flange inner circle machining method, which includes the above-mentioned inner circle machining automatic device, and also includes the following steps: a. Pre-processing of materials: a square material 13 is processed by laser cutting, and the material 13 is transferred to the conveying mechanism 1. The pre-processing is a process of centrally processing the material 13 by laser cutting equipment.

[0045] b. Loading of the material 13: The square material 13 is transferred to the inlet side of the punching mechanism 5 by the conveying mechanism 1, and then loaded by the loading mechanism and positioned by the positioning assembly. This process is the specific loading process of the material 13.

[0046] c. Positioning of the material 13: The positioning component starts to start when the material 13 leaves the feeding mechanism and positions the material 13 on the punching station of the punching mechanism 5, and then the positioning component is reset. This process is the positioning process of the material 13. Positioning enables the punching mechanism 5 to punch holes at appropriate positions of the material 13 to ensure product quality.

[0047] d. Punching of the material 13: The punching mechanism punches out the material 13 to produce a suitable inner circle. The punch 11 of the punching mechanism 5 can punch out the inner circle.

[0048] e. Post-processing of the material 13: The material 13 with the inner circle punched out is transferred to the grinding station, and the grinding station grinds the inner circle. The grinding process can eliminate the burrs caused by the punching process.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
