[0038] The embodiment of the present application discloses a workpiece shaping device for shaping and flattening a metal workpiece 5. The metal workpiece 5 is a cuboid block as a whole, and a U-shaped groove 51 for product resting is arranged in the middle of the length direction of the metal workpiece 5. The arrangement of the U-shaped groove 51 makes the middle part of the metal workpiece 5 thinner, and deformation and bending are prone to occur on both sides of the U-shaped groove 51 after long-term use.

[0039] Embodiment 1:

[0040] Reference Figure 3 The workpiece shaping device comprises a fixed bottom plate 1, a supporting pad 2 and a pressing assembly 3. The fixed bottom plate 1 is a rectangular block, which is placed on the ground or an operation table. The width of the fixed bottom plate 1 is greater than the width of the metal workpiece 5. The supporting pad 2 comprises a first pad 21 and a second pad 22.

[0041] The first cushion block 21 is arranged along the width direction of the fixed base plate 1, and the top of the first cushion block 21 has a positioning hole 211 for inserting the metal workpiece 5. The second cushion block 22 is arranged on both sides of the first cushion block 21 respectively. The two cushion blocks can be fixed on the fixed base plate 1 by bolts or welding, etc. In this embodiment, the first and second cushion blocks 22 are fixed on the fixed base plate 1 by bolts. The first cushion block 21 corresponds to the U-shaped groove 51 of the metal workpiece 5, and is used to support the middle part of the metal workpiece 5. The height of the second cushion block 22 is flush with the first cushion block 21, and is used to support the two ends of the metal workpiece 5, so as to ensure that the two ends of the workpiece are in parallel after shaping.

[0042] Referring to Figure 3 and Figure 4 , the pressing assembly 3 includes a lifting plate 31, a pressing plate 32 fixed on the bottom of the lifting plate 31, and a guide rod 33 in sliding cooperation with the lifting plate 31. The guide rod 33 is fixed on both ends of the fixed base plate 1 in the length direction, and the two guide rods 33 are respectively close to the two corresponding opposite corners of the fixed base plate 1. The lifting plate 31 is consistent in size with the fixed base plate 1, and has a sliding hole 311 penetrating through the two side end faces and for inserting the guide rod 33 on both sides in the length direction.

[0043] The pressing plate 32 is arranged on the bottom of the lifting plate 31 on both sides, and the two pressing plates 32 are arranged correspondingly with the two second cushion blocks 22 respectively. The top of the pressing plate 32 is fixed with a hinge seat 321, and a hinge shaft 323 is arranged on the hinge seat 321. The hinge seat 321 and the pressing plate 32 are welded or bolted. The bottom of the pressing plate 32 is fixed with a hinge joint 312. The hinge seat 321 has a hinge groove 322 for inserting the hinge joint 312. The hinge shaft 323 penetrates the hinge seat 321 and the hinge seat 321, realizing the hinged cooperation of the pressing plate 32 and the lifting plate 31.

[0044] When the operator operates, the metal workpiece 5 is placed on the top of the supporting cushion block 2, and then the lifting plate 31 is pressed downward, so that the pressing plate 32 abuts against the metal workpiece 5. Through the hinged cooperation of the pressing plate 32 and the lifting plate 31, the pressing plate 32 can always adhere to the top surface of the two ends of the metal workpiece 5 during the pressing process, so as to increase the contact area of the pressing plate 32 and the metal workpiece 5 and improve the pressing stability; continue to press the lifting plate 31 downward until the bottom surface of the two sides of the metal workpiece 5 adheres to the second cushion block 22.

[0045] In order to reduce the probability of the lifting plate 31 from sliding and affecting the placement of the workpiece, the guide rod 33 is sequentially provided with a wear-resistant section 331 and a smooth section 332 along the height direction. The wear-resistant section 331 can be a wear-resistant pattern arranged on the guide rod 33, or a damping sleeve sleeved on the guide rod 33. The wear-resistant section 331 is located at the top of the guide rod 33, and when the sliding hole 311 is located at the wear-resistant section 331, the lifting plate 31 can be positioned, thereby reducing the probability of the lifting plate 31 from sliding.

[0046] With reference to Figure 4 and Figure 5 , the guide rod 33 is further provided with a mounting groove 3311 extending along the horizontal direction at the wear-resistant section 331.

Through the cooperation of the plunger ball head and the locking hole 313, the stability of the lifting plate 31 is further improved. At the same time, the operator only needs to push the lifting plate 31 to separate the plunger ball head from the locking hole 313, thereby achieving unlocking.

[0049] With reference to Figure 6 and Figure 7 , in order to position and place the metal workpiece 5 before shaping, the fixed base plate 1 is further provided with a positioning assembly 4.

The fixed base plate 1 is provided with a driving support 12 on the side away from the mounting seat 11 of the first positioning plate 41. The driving gear 433 is rotatably mounted on the driving support 12. The driving rotating rod 434 is coaxially fixed with the driving gear 433. By rotating the driving rotating rod 434, the driving gear 433, the driven gear and the driving screw 431 are driven to rotate, thereby driving the horizontal movement of the second positioning plate 42. In other embodiments, the driving rotating rod 434 can be replaced by a rotary motor.

[0053] The implementation principle of the workpiece shaping device in the embodiment of the application is as follows: before the shaping operation, the lifting plate 31 is located in the wear-resistant section 331 as a whole, and the elastic plunger 333 and the locking hole 313 are matched and locked; the metal workpiece 5 is horizontally inserted into the positioning gap from one end of the width direction of the fixed base plate 1; the driving rotating rod 434 is rotated to drive the second positioning plate 42 to move horizontally towards the metal workpiece 5 until the first positioning plate 41 and the second positioning plate 42 clamp and position the metal workpiece 5; the operator pushes the lifting plate 31 downward to move the lifting plate 31 from the wear-resistant section 331 to the smooth section 332, and continues to push downward after the compression plate 32 is attached to the metal workpiece 5, so that the metal workpiece 5 is gradually deformed from the curved state to the horizontal state under the action of the compression plate 32.

[0054] Embodiment 2:

[0055] The embodiment is different from the embodiment 1 in the structure of the positioning assembly 4, and the rest of the structures are consistent with the embodiment 1.
