Description

Technical Field

[0001] The utility model belongs to the technical field of metal product tooling, and particularly relates to a shaping bench for metal flat workpieces after machining. Background Technique

[0002] During the cutting process of metal flat plates, machining stress will be generated, which will cause the metal flat plates to deform, especially the deformation of thin metal flat plates is more serious. In order to ensure that the flatness of the metal flat plate can meet the design requirements, the machined metal flat plate needs to be corrected manually. The general correction method is to place the metal flat plate workpiece on the platform and correct it by manually knocking the deformed part. However, this correction method extremely relies on the worker's technique. Among different workers, there are very large differences in the time required to correct the deformed metal flat plate workpiece and the correction effect. Therefore, this technical means of manually correcting deformed metal flat plate workpieces severely restricts the overall production efficiency and quality reliability. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a shaping bench for metal flat workpieces after machining, which is used to solve the technical problem that the deformed metal flat plate workpiece in the prior art needs to be manually corrected, and this correction method severely restricts the production efficiency and quality reliability.

[0004] The technical solution of the utility model to solve the above technical problem is as follows: A shaping bench for metal flat workpieces after machining, comprising:

[0005] A bottom plate, each of the four corners of the bottom plate is provided with a support column, and the top surface of the bottom plate is a plane;

[0006] A top plate, the top plate is connected to the tops of the four support columns, and a plurality of round holes and a plurality of waist-shaped holes are also opened on the top plate, and the round holes and the waist-shaped holes are used to install pneumatic hammers or cylinders;

[0007] Four locking components, the four locking components are respectively sleeved on the support columns, and the four locking components are used to fix the metal flat plate workpiece on the top surface of the bottom plate.

[0008] The bottom plate of the utility model serves as a platform for the correction operation of the metal flat plate workpiece. Then, the metal flat plate workpiece is fixed on the bottom plate by using the locking components. Then, whether it is to detect the size of the gap between the metal flat plate workpiece and the bottom plate or to detect the distance between the bottom surface of the top plate and the metal flat plate workpiece, the deformed part of the metal flat plate workpiece can be accurately found. Then, at the position corresponding to the deformed part, a pneumatic hammer or a cylinder is installed on the top plate, and the deformed part is restored to be flat by pressing down the cylinder or repeatedly hammering with the pneumatic hammer.

[0009] Further: The pneumatic hammer or the cylinder is connected to the top plate through a connecting block.

[0010] Beneficial effects of this step: The position of the pneumatic hammer or cylinder corresponding to the deformed part can be adjusted more accurately through the connecting block, and the height between the two and the stroke of the pneumatic hammer or cylinder are more matched.

[0011] Furthermore: The support column includes a column body and threaded rods at both ends of the column body, and the diameter of the threaded rod is smaller than the diameter of the column body.

[0012] Beneficial effects of this step: The distance between the top plate and the bottom plate is ensured to be more accurate through the support column, ensuring that the top plate and the bottom plate are in a parallel state, and better ensuring the correction effect.

[0013] Furthermore: The locking assembly includes:

[0014] A locking rod, one end of the locking rod is provided with a locking ring, the locking ring is sleeved on the support column, and the other end of the locking rod is provided with a threaded hole;

[0015] A screw rod, the screw rod is screwed into the threaded hole, and a square column is provided at the top of the screw rod;

[0016] A handle, the handle is sleeved on the square column;

[0017] A pressing block, the pressing block is provided at the bottom of the screw rod.

[0018] Beneficial effects of this step: Since the locking rod can rotate and move up and down on the support column, the locking rod that moves up and down can adapt to metal flat workpiece of different thicknesses, and the rotating locking rod can correspond to the plane of the metal flat workpiece itself after adjustment; then rotate the screw rod to press the pressing block tightly on the metal flat workpiece to achieve the purpose of fixation.

[0019] Furthermore: The bottom of the screw rod is a ball head, and the pressing block is sleeved on the ball head.

[0020] Beneficial effects of this step: When the top surface of the metal flat workpiece is an inclined surface, the pressing block can rotate freely on the ball head, so that the pressing block can automatically adapt to the inclined surface, improving the applicability of the locking assembly.

[0021] Furthermore: Reinforcing ribs are welded on the top surface of the top plate.

[0022] Beneficial effects of this step: The reinforcing ribs are to enhance the structural strength of the top plate and prevent the top plate from deforming under the reaction force of the pneumatic hammer or cylinder.

[0023] The beneficial effects of the present utility model are:

[0024] 1. First, the present application can fix a metal flat workpiece on the bottom plate by using a movable locking component. The movable locking component is suitable for metal flat workpieces with different top surface shapes. Then, whether detecting the distance between the metal flat workpiece and the top plate or the bottom plate, the deformed part can be quickly found. Finally, a pneumatic hammer or a cylinder can be installed on the top plate at the position corresponding to the deformed part, and correction can be achieved by continuous pressing of the cylinder or repeated hammering of the pneumatic hammer. Moreover, repeated hammering with the pneumatic hammer can also release the internal stress of the metal flat workpiece. These operation processes can be standardized, greatly reducing the individual differences among operators and improving the efficiency of the correction operation.

[0025] 2. When used in combination with a pneumatic hammer or a cylinder, both the fixing torque of the locking component, the pneumatic pressure of the cylinder or the pneumatic hammer, and even the knocking frequency of the pneumatic hammer are adjustable and controllable. Appropriate parameters can be selected according to the thickness, material mechanical properties, etc. of the metal flat workpiece, improving the quality reliability of the correction operation.

[0044] Embodiment

[0045] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 shown, a post-forming bench for metal flat workpieces provided by the present utility model includes:

[0046] A bottom plate 1, with a support column 2 provided at each of the four corners of the bottom plate 1. The top surface of the bottom plate 1 is a flat surface, and the bottom plate 1 can be used as a correction platform;

[0047] A top plate 3, connected to the tops of the four support columns 2. A plurality of round holes 31 and a plurality of waist-shaped holes 32 are also provided on the top plate 3. The round holes 31 and the waist-shaped holes 32 are used for installing pneumatic hammers or cylinders. The plurality of round holes 31 and the plurality of waist-shaped holes 32 can provide multiple installation positions to facilitate aligning the pneumatic hammer or cylinder 5 with the deformed position of the metal flat workpiece 6;

[0048] Four locking assemblies 4, respectively sleeved on the support columns 2, and the four locking assemblies 4 are used to fix the metal flat workpiece 6 on the top surface of the bottom plate 1.

[0049] The bottom plate 1 of the present utility model serves as a platform for the correction operation of the metal flat workpiece 6. Then, the metal flat workpiece 6 is fixed on the bottom plate 1 by using the locking assembly 4. Then, whether detecting the size of the gap between the metal flat workpiece 6 and the bottom plate 1 or detecting the distance between the bottom surface of the top plate 3 and the metal flat workpiece 6, the deformed part of the metal flat workpiece 6 can be accurately and quickly found. Then, at the position corresponding to the deformed part, the pneumatic hammer or cylinder 5 is installed on the top plate 3, and the deformed part is restored to be flat by continuously pressing with the cylinder or repeatedly hammering with the pneumatic hammer.

[0050] Based on the above technical solution, the pneumatic hammer or cylinder 5 is connected to the top plate 3 through a connecting block 51.

[0051] The connecting block 51 has two main functions. One is that by selecting a suitable connecting block 51, the position of the pneumatic hammer or cylinder 5 corresponding to the deformed part can be adjusted more accurately, and the height between the two and the stroke of the pneumatic hammer or cylinder 5 are more matched. The other is that the contact area between the connecting block 51 and the pneumatic hammer or cylinder 5 is large, and the pneumatic hammer or cylinder 5 can be stably fixed.

[0052] On the basis of the above technical solution, the support column 2 includes a column body and threaded rods at both ends of the column body, and the diameter of the threaded rod is smaller than the diameter of the column body.

[0053] The structure of the support column 2 enables the two ends of the column body to limit the bottom plate 1 and the top plate 3. By the support column 2, the distance between the top plate 3 and the bottom plate 1 is more accurate, ensuring that the top plate 3 and the bottom plate 1 are in a parallel state, and further ensuring the correction effect.

[0054] As Figure 5 and Figure 6 shown, the locking assembly 4 includes:

[0055] A locking rod 41, one end of the locking rod 41 is provided with a locking ring 411, the locking ring 411 is sleeved on the support column 2, and the other end of the locking rod 41 is provided with a threaded hole 412;

[0056] A screw rod 42, the screw rod 42 is screwed into the threaded hole 412, and the top of the screw rod 42 is provided with a square column;

[0057] A handle 43, the handle 43 is sleeved on the square column;

[0058] A pressing block 44, the pressing block 44 is arranged at the bottom of the screw rod 42.

[0059] Since the locking rod 41 can rotate and move up and down on the support column 2 by using the locking ring 411, the locking rod 41 moving up and down can adapt to metal flat workpiece 6 with different thicknesses, and the rotating locking rod 41 can correspond to the plane of the metal flat workpiece 6 itself after adjustment; then rotate the screw rod 42 to press the pressing block 44 tightly on the metal flat workpiece 6 to achieve the purpose of fixation. Among them, the screw rod 42 can be rotated by the handle 43 to a nearly locked state, and then a force measuring tool such as a torque wrench is used to lock the screw rod 42, so that it can be locked and the metal flat workpiece 6 is prevented from being damaged. The square column is a general style designed to cooperate with tools such as torque wrenches.

[0060] On the basis of the above technical solution, the bottom of the screw rod 42 is a ball head, and the pressing block 44 is sleeved on the ball head. The structure of the pressing block 44 can be two upper and lower blocks, the upper block is sleeved on the screw rod 42, and the top surface of the lower block is provided with a spherical groove.

[0061] When the top surface of the metal flat workpiece 6 is an inclined surface, the pressing block 44 can rotate freely on the spherical head, so that the pressing block 44 can automatically adapt to the inclined surface, improving the applicability of the locking assembly 4.

[0062] On the basis of the above technical solution, a reinforcing rib is welded to the top surface of the top plate 3.

[0063] The position of the reinforcing rib does not interfere with the round hole 31 and the waist-shaped hole 32. The reinforcing rib is to enhance the structural strength of the top plate 3 and prevent the top plate 3 from deforming under the reaction force of the pneumatic hammer or the cylinder 5.

[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention 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 on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
