Description

Technical Field

[0001] The utility model relates to the field of machining, and specifically relates to an anti-bending tooling. Background Art

[0002] In the field of machining, due to the unique physical properties of magnetically-attached thin workpieces, they often face a challenge during the post-processing after machining. Since the bottom of the workpiece is magnetically attached, when directly picking it up from a metal placement tabletop, a strong magnetic force will be generated between the bottom of the workpiece and the tabletop. This magnetic force causes the workpiece to be prone to local lifting during the picking-up process, especially when the edge of the workpiece or local stress is uneven. This uneven stress will cause the workpiece to bend and deform, seriously affecting the shape accuracy and surface quality of the product, and thus reducing the overall performance of the product. Therefore, developing a tooling device that can effectively prevent magnetically-attached thin workpieces from bending and deforming during the picking-up process has become a technical problem that urgently needs to be solved in the field of machining.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Reference Figures 1-3, a bending prevention tooling, including a base 1. The base 1 can be a rectangular block, serving as the supporting part of the entire tooling, used to fix the tooling and place workpieces. A lifting device 2 is provided on the base 1. The lifting device 2 includes two lifting units symmetrically arranged on the top of the base 1. Each lifting unit includes a fixed plate 21 and a movable plate 22. The fixed plate 21 is fixedly arranged on the top of the base 1 and can be fixed by welding, integral molding, etc. The movable plate 22 is inserted on the fixed plate 21 and can vertically lift along the fixed plate 21. A pushing and pulling device 4 is arranged between the two movable plates 22. The overall lifting of the pushing and pulling device 4 is driven by the lifting of the two movable plates 22.

[0020] A locking and adjusting device 3 is provided on the lifting device 2. A pushing and pulling device 4 is provided on the top of the lifting device 2. A magnetic isolation part 5 is provided on the pushing and pulling device 4. The height of the pushing and pulling device 4 on the lifting device 2 is adjusted through the locking and adjusting device 3, and the magnetic isolation part 5 is pushed onto the metal placement table through the pushing and pulling device 4. Thus, a magnetized thin workpiece can be placed on the magnetic isolation part 5 for processing, separating the magnetized thin workpiece from the metal placement table surface, eliminating the influence of the magnetic force on the magnetized thin workpiece, and avoiding bending deformation of the magnetized thin workpiece during the picking-up process, thereby ensuring the shape accuracy, surface quality, and overall performance of the product.

[0021] The locking and adjusting device 3 can include at least four locking bolts 31. The four locking bolts 31 are symmetrically arranged on the mutually remote sides of the two movable plates 22. One side of the locking bolt 31 penetrates the side surface of the movable plate 22 and is in screw connection with the movable plate 22, and abuts against the side surface of the fixed plate 21. By tightening the four locking bolts 31, the end of the locking bolt 31 presses the fixed plate 21, thereby realizing the adjustment of the height position of the movable plate 22 on the fixed plate 21.

[0022] The pushing and pulling device 4 includes a chute 41, a pulley 42, and a rotating roller 43. The chute 41 is arranged on the mutually close sides of the two movable plates 22. A pulley 42 is arranged in the chute 41, and the pulley 42 can slide along the chute 41. A magnetic isolation part 5 is arranged between the two pulleys 42. The pushing and pulling device 4 further includes at least two rotating rollers 43. The two sides of the rotating roller 43 are respectively axially connected to the two movable plates 22, and the rotating roller 43 is arranged at one end of the movable plate 22 far from the connecting plate 23. The circumferential surface of the rotating roller 43 contacts the bottom of the magnetic isolation part 5. When the pulley 42 drives the magnetic isolation part 5 to slide, it can provide the supporting force at the bottom of the magnetic isolation part 5, assist the sliding of the magnetic isolation part 5, and improve the sliding stability of the magnetic isolation part 5; at the same time, it can strengthen the connection strength between the two movable plates 22 and improve the synchronism and stability of the lifting process of the movable plate 22. With the design of the pushing and pulling device 4, the workpiece can be picked up after being completely separated from the metal placement table by the magnetic isolation part 5. Thus, there is no metal placement table during the picking-up process of the workpiece, avoiding the magnetic force between the magnetized thin workpiece and the metal placement table, thereby improving work efficiency and ensuring product quality.

[0023] In some embodiments, one end of two movable plates 22 is provided with a connecting plate 23, which can strengthen the connection strength between the two movable plates 22 and improve the synchronism and stability of the movable plates 22 during the lifting process.

[0024] In some embodiments, the magnetic isolation member 5 can be a tungsten plate, which has good magnetic isolation performance and can effectively isolate the magnetism at the bottom of the workpiece, thereby preventing the workpiece from bending due to magnetism.

[0025] In some embodiments, universal wheels 6 are provided at the four corners of the base 1, which is convenient for the movement of the anti-bending tooling and improves the convenience of the application of the anti-bending tooling.

[0026] The specific working principle is as follows:

[0027] When specifically implementing the present utility model, first, by rotating multiple universal wheels 6, the present utility model is moved to the corresponding position on the processing platform, and the universal wheels 6 are ensured to be locked or stable to prevent the tooling from moving during work.

[0028] According to the height of the processing table surface required for the magnetized thin workpiece, the lifting device 2 is adjusted. By rotating the locking bolt 31 in the locking adjustment device 3, the movable plate 22 is vertically lifted on the fixed plate 21 until the height of the bottom of the magnetic isolation member 5 matches the height of the processing table surface. After the adjustment is completed, the locking bolt 31 abuts against the side surface of the fixed plate 21 to fix the movable plate 22.

[0029] Then, the magnetic isolation member 5 is pushed. The magnetic isolation member 5 slides along the chute 41 through the pulleys 42 symmetrically arranged at both ends, so that the magnetic isolation member 5 can move along the horizontal direction of the movable plate 22, thereby placing the magnetic isolation member 5 on the processing table surface, and then placing the magnetized thin workpiece to be processed on the magnetic isolation member 5, so that the magnetism of the magnetized thin workpiece is isolated by the magnetic isolation member 5.

[0030] After the processing of the magnetized thin workpiece is completed, the magnetic isolation member 5 is pushed in the reverse direction, so that the magnetic isolation member 5 is pushed out under the action of the pushing and pulling device 4 and separated from the processing table surface, and then the magnetized thin workpiece is directly taken to complete the processing of the magnetized thin workpiece.

[0031] The above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
