Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of profile correction, and particularly relates to a stamping correction equipment for profile steel members. BACKGROUND

[0002] The profile steel member generally refers to a profile member with a relatively long length and a constant cross section. Such a member is prone to bending due to stress release or self weight during long-term storage or transportation. Before use, the small-amplitude bending needs to be corrected. The current correction device is mainly used for cold correction through the rolling wheel extrusion. Such a structure is simple, but is only suitable for the profile with a flat top. If the top of the profile is a curved surface or a stepped surface or other non-planar form, the contact surface between the extrusion punch and the workpiece will be greatly reduced, even changed into line contact or point contact. Under the action of such local pressure, the bending of the profile may not be corrected, and local pits may appear first.

[0003] Therefore, for the non-planar profile correction surface, a correction equipment capable of sharing the pressure needs to be designed. SUMMARY

[0004] In view of the above problems, the present application provides a stamping correction equipment for profile steel members. The present application adopts multiple independent profiling columns for sharing the extrusion pressure through pressure equalization pushing, and cooperates with the articulated feet capable of turning, so as to realize uniform extrusion of the curved surface workpiece. However, even if the pressure of each profiling column is the same, due to the different strengths of each part of the profile, the bending of the profile may not be corrected, and local deformation may appear first at the edge. In order to completely solve this problem, the present application provides a caliper fixing assembly and a double-cavity hydraulic assembly. Through the closed hydraulic transmission, the position of each profiling column can be automatically locked after profiling, so as to avoid the deformation of the weak part of the profile.

[0005] The technical scheme adopted by the present application is as follows: the present application provides a stamping correction equipment for profile steel members, which comprises an independent profiling assembly, a caliper fixing assembly, a double-cavity hydraulic assembly, a caliper supercharging assembly, a lifting assembly, a gantry and a conveying assembly. The independent profiling assembly is arranged below the lifting assembly. The lifting assembly is arranged on the gantry. The caliper fixing assembly is symmetrically arranged on the side surface of the independent profiling assembly. The double-cavity hydraulic assembly is arranged on the independent profiling assembly. The caliper supercharging assembly is arranged in the double-cavity hydraulic assembly. The conveying assembly is arranged below the independent profiling assembly. The independent profiling assembly comprises a brake seat, a profiling column and an articulated foot. The brake seat is provided with a through longitudinal hole in array. The profiling column is slidingly arranged in the longitudinal hole. The articulated foot is hinged to the bottom of the profiling column.

[0006] Before applying pressure, multiple independent contour columns can be used to contour the top surface of the profile, thereby applying pressure evenly to the extrusion location and avoiding uneven stress that could lead to localized deformation of the profile.

[0007] Furthermore, the caliper fixing assembly includes a caliper seat, a piston caliper, and a hydraulic pipe. The brake seat has symmetrical transverse grooves on both sides. The caliper seat is fixed in the transverse grooves. The piston caliper is engaged and slidably disposed in the caliper seat. One end of the hydraulic pipe is connected to the caliper seat.

[0008] After the profile is formed, the piston caliper can lock the relative position of each set of profile columns, thereby avoiding local deformation due to the different strengths of different parts of the profile during the pressure application process.

[0009] Furthermore, the dual-chamber hydraulic assembly includes a hydraulic box and a hydraulic cylinder. The hydraulic box is fixedly connected to the top of the brake seat. The top of the contour column is located inside the hydraulic box. A cylindrical portion is provided above the hydraulic box. The hydraulic cylinder is fixedly connected to the top of the cylindrical portion. The hydraulic cylinder and the hydraulic box are connected.

[0010] Preferably, the dual-chamber hydraulic assembly further includes a lower piston, which is engaged and slidably disposed in a hydraulic cylinder. The inner wall of the hydraulic cylinder is provided with a stepped ring, and the lower piston is located below the stepped ring.

[0011] Even if the protrusions of the various contoured columns are different, the hydraulic pressure they experience in the hydraulic box is the same. Through the technology of equalizing pressure in the same cavity, not only can multiple hard rubber blocks simultaneously press against the workpiece, but the downward pressure on each part can also be the same during the correction.

[0012] Furthermore, the caliper booster assembly includes an upper piston and a return spring. The upper piston is engaged and slidably disposed in the hydraulic cylinder. The upper piston is located above the stepped ring, and the return spring is disposed between the lower piston and the upper piston.

[0013] By moving the lower and upper pistons closer together and further apart, the extension and retraction of the piston calipers can be controlled synchronously, thereby achieving the technical effect of "automatically locking each contour post when pressure is applied and automatically unlocking when no pressure is applied".

[0014] Preferably, the other end of the hydraulic pipe is connected to the hydraulic cylinder, and the hydraulic pipe is located between the lower piston and the upper piston.

[0015] As a further preferred embodiment of the present invention, the independent contouring component further includes a hard rubber block, which is fixedly attached to the underside of the hinge foot.

[0016] Furthermore, the lifting assembly includes a lifting nut, a lifting screw, and a guide rod. The lifting nut is rotatably mounted in the gantry frame, and there is a threaded transmission between the lifting screw and the lifting nut. The bottom of the lifting screw is fixed to the upper piston, and the guide rod is fixed to both ends of the hydraulic box. The guide rod is engaged and slidably mounted in the gantry frame.

[0017] When the lifting nut rotates, the longitudinal movement of the lifting screw controls the lifting and lowering of the upper piston, thereby controlling the shaping, locking, and pressing processes of this device.

[0018] Furthermore, the conveying assembly includes a frame, a roller seat, and conveying rollers, with the roller seat mounted on the frame and the conveying roller array mounted on the roller seat.

[0019] Preferably, the conveying assembly further includes a photoelectric gate, which is disposed on the roller seat.

[0020] The photoelectric gate can sense the correction range of the workpiece, thus avoiding overcorrection.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Before applying pressure, multiple independent contour columns can be used to contour the top surface of the profile, thereby applying pressure evenly to the extrusion position and avoiding the problem of uneven force causing local deformation of the profile.

[0022] (2) After the contouring of the profile column is completed, the relative positions of each group of profile columns can be locked by the piston caliper, thereby avoiding the problem of local deformation due to the different strengths of different parts of the profile during the pressure process.

[0023] (3) Even if the extension of each contour column is different, the hydraulic pressure it receives in the hydraulic box is the same. By using the pressure equalization technology in the same cavity, not only can multiple hard rubber blocks press against the workpiece at the same time, but also the downward pressure of each part during the correction is the same.

[0024] (4) By moving the lower piston and the upper piston closer and further apart, the extension and retraction of the piston caliper can be controlled synchronously, thereby achieving the technical effect of "automatically locking each contour post when pressure is applied and automatically unlocking when no pressure is applied".

[0025] (5) When the lifting nut rotates, the lifting piston can be controlled by the longitudinal movement of the lifting screw, thereby controlling the shaping, locking and pressing processes of this device.

[0026] (6) The photoelectric gate can sense the correction range of the workpiece and avoid overcorrection. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] like Figures 1-9 As shown, the present invention proposes a stamping straightening device for profile steel components, including an independent contouring component 1, a caliper fixing component 2, a dual-chamber hydraulic component 3, a caliper pressurizing component 4, a lifting component 5, a gantry frame 6, and a conveying component 7. The independent contouring component 1 is located below the lifting component 5, the lifting component 5 is located on the gantry frame 6, the caliper fixing component 2 is symmetrically arranged on the side of the independent contouring component 1, the dual-chamber hydraulic component 3 is located on the independent contouring component 1, the caliper pressurizing component 4 is located in the dual-chamber hydraulic component 3, and the conveying component 7 is located below the independent contouring component 1. The independent contouring component 1 includes a brake seat 11, a contouring column 12, and a hinged foot 13. The brake seat 11 has an array of through longitudinal holes 111. The contouring column 12 is engaged and slidably disposed in the longitudinal holes 111. The hinged foot 13 is hinged to the bottom of the contouring column 12.

[0033] Before applying pressure, multiple independent contour columns 12 can first contour the top surface of the profile, thereby applying pressure evenly to the extrusion position and avoiding the problem of local deformation of the profile caused by uneven force.

[0034] The caliper fixing assembly 2 includes a caliper seat 21, a piston caliper 22, and a hydraulic pipe 23. The brake seat 11 has symmetrical transverse grooves 112 on both sides. The caliper seat 21 is fixed in the transverse grooves 112. The piston caliper 22 is engaged and slidably disposed in the caliper seat 21. One end of the hydraulic pipe 23 is connected to the caliper seat 21.

[0035] After the contouring of the profile column 12 is completed, the piston caliper 22 can lock the relative position of each group of profile columns 12, thereby avoiding the problem of local deformation due to the different strengths of different parts of the profile during the pressure application process.

[0036] The dual-chamber hydraulic assembly 3 includes a hydraulic box 31 and a hydraulic cylinder 32. The hydraulic box 31 is fixedly connected to the top of the brake seat 11. The top of the contour column 12 is located inside the hydraulic box 31. A cylindrical part 311 is provided above the hydraulic box 31. The hydraulic cylinder 32 is fixedly connected to the top of the cylindrical part 311. The hydraulic cylinder 32 and the hydraulic box 31 are connected.

[0037] The dual-chamber hydraulic assembly 3 also includes a lower piston 33, which is engaged and slidably disposed in the hydraulic cylinder 32. The inner wall of the hydraulic cylinder 32 is provided with a stepped ring 321, and the lower piston 33 is located below the stepped ring 321.

[0038] Even if the protrusions of the various contoured columns 12 are different, the hydraulic pressure they receive in the hydraulic box 31 is the same. Through the pressure equalization technology in the same cavity, not only can multiple hard rubber blocks 14 simultaneously press against the workpiece, but the downward pressure of each part during the correction is also the same.

[0039] The caliper booster assembly 4 includes an upper piston 41 and a return spring 42. The upper piston 41 is engaged and slidably disposed in the hydraulic cylinder 32. The upper piston 41 is located above the stepped ring 321. The return spring 42 is disposed between the lower piston 33 and the upper piston 41.

[0040] By moving the lower piston 33 and the upper piston 41 closer and further apart, the extension and retraction of the piston caliper 22 can be controlled synchronously, thereby achieving the technical effect of "automatically locking each contour post 12 when pressure is applied and automatically unlocking when no pressure is applied".

[0041] The other end of the hydraulic pipe 23 is connected to the hydraulic cylinder 32, and the hydraulic pipe 23 is located between the lower piston 33 and the upper piston 41.

[0042] The independent contouring component 1 also includes a hard rubber block 14, which is fixed to the underside of the hinge foot 13.

[0043] The lifting assembly 5 includes a lifting nut 51, a lifting screw 52, ​​and a guide rod 53. The lifting nut 51 is rotatably mounted in the gantry frame 6. The lifting screw 52 and the lifting nut 51 are connected by a threaded transmission. The bottom of the lifting screw 52 is fixed to the upper piston 41. The guide rod 53 is fixed to both ends of the hydraulic box 31 and is engaged and slidably mounted in the gantry frame 6.

[0044] When the lifting nut 51 rotates, the vertical movement of the lifting screw 52 can control the lifting of the upper piston 41, thereby controlling the shaping, locking and pressing processes of this device.

[0045] The conveying assembly 7 includes a frame 71, a roller seat 72, and conveying rollers 73. The roller seat 72 is mounted on the frame 71, and the conveying rollers 73 are arranged in an array on the roller seat 72.

[0046] The conveying assembly 7 also includes a photoelectric gate 74, which is mounted on the roller seat 72.

[0047] The photoelectric gate 74 can sense the correction range of the workpiece, thus avoiding overcorrection.

[0048] In practical use, the user first needs to place the bent profile on the conveying roller 73 and make the arching direction upward; then, the workpiece is conveyed to the designated position by the conveying roller 73 manually or automatically. Generally, the highest point of the arch should be located directly below the independent contouring component 1.

[0049] Then, the lifting nut 51 is rotated by the motor. When the lifting nut 51 and the lifting screw 52 rotate relative to each other, the lifting screw 52 will descend and bring the independent contouring component 1, the caliper fixing component 2, the dual-chamber hydraulic component 3 and the caliper pressurizing component 4 down as a whole until the hard rubber block 14 contacts the top surface of the workpiece.

[0050] After a hard rubber block 14 contacts the top surface of the workpiece, the brake seat 11 continues to descend, and the corresponding contour column 12 will retract into the brake seat 11 until all the hard rubber blocks 14 contact the top surface of the workpiece. During the process of the profile column 12 retracting into the brake seat 11, the profile column 12 will occupy the space inside the hydraulic box 31. Therefore, the lower piston 33 will gradually rise relative to the hydraulic cylinder 32 under the push of the liquid until the lower piston 33 touches the step ring 321.

[0051] The contouring stage is now complete, and the locking stage begins. The upper piston 41 continues to press down. Since the contouring column 12 cannot retract relative to the brake seat 11 at this time, and the bottom of the contouring column 12 has already pressed against the workpiece, the brake seat 11 will remain stationary during the locking stage. As the upper piston 41 and the lower piston 33 approach each other, the fluid between the upper piston 41 and the lower piston 33 enters the caliper seat 21 through the hydraulic pipe 23, thereby pushing the piston caliper 22 to extend. The piston caliper 22 presses against and squeezes the sides of the contour post 12 from both sides, thereby locking multiple contour posts 12 relative to the brake seat 11.

[0052] Then, the extrusion stage begins. After the contour column 12 is locked, the independent contour assembly 1, the caliper fixing assembly 2, the dual-chamber hydraulic assembly 3, and the caliper pressurizing assembly 4 descend as a whole and extrude the workpiece below. During the extrusion process, since the caliper seat 21 always maintains a high pressure, and the greater the correction pressure, the greater the hydraulic pressure, the piston caliper 22 can maintain the locking effect on the contour column 12.

[0053] The photoelectric gate 74 is flush with the highest point of the conveying roller 73. When the workpiece is squeezed to the point of blocking the light of the photoelectric gate 74, the correction can be stopped and the workpiece can be reset. Due to the presence of the reset spring 42, the piston caliper 22 has a tendency to retract in its natural state.

[0054] If the profile is flexible, the height of the photoelectric gate 74 can be appropriately lowered to compensate for the elasticity through overcorrection; if overcorrection occurs, the profile needs to be flipped over and recorrected.

[0055] In another embodiment of the present invention, the lifting nut 51 can be set to a fixed form, and the lifting screw 52 can be rotated by a motor, so that there is relative rotation between the lifting nut 51 and the lifting screw 52.

[0056] As another embodiment of the present invention, the screw drive of the lifting nut 51 and the lifting screw 52 can also be converted into an electric push rod or a hydraulic push rod, which can drive the upper piston 41 to rise and fall.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
