Description

Technical Field

[0001] This utility model relates to the field of stamping processing technology, specifically to a surface treatment device for metal stamping parts. Background Technology

[0002] Surface treatment equipment for metal stampings is mainly used to improve their surface quality and corrosion resistance. Hot-dip galvanizing is a common process for surface treatment of metal stampings. Specifically, the steel material to be plated is immersed in molten plating metal and then taken out and cooled to form a metal coating on its surface. It can provide excellent corrosion resistance. Hot-dip galvanizing can be used for different types of metals.

[0003] The prior art patent document with publication number CN221895083U provides a surface treatment device for metal stamping parts, including a hot-dip galvanizing tank. By setting up a hot-dip galvanizing tank, a clamping mechanism, a lifting mechanism, and a suspension mechanism, the metal stamping parts are aligned with the clamping plates on both sides. Then, an electric rod is activated to move the clamping plates through a moving rod. After the clamping plates stably clamp the metal stamping parts, a servo motor is activated, and a telescopic rod quickly drives the clamping mechanism to dock with the inner cavity of the hot-dip galvanizing tank, thereby achieving the effect of quickly hot-dip galvanizing the metal stamping parts. After the hot-dip galvanizing treatment is completed, the servo motor is activated again, and the telescopic rod drives the clamping mechanism and the metal stamping parts to detach from the hot-dip galvanizing tank. The electric rod is activated to detach the metal stamping parts from the clamping and place them in the inner cavity of the suspension frame, so that excess coating on the surface of the metal stamping parts can drip into the inner cavity of the hot-dip galvanizing tank.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the clamping plate is in close contact with the metal stamping part, and the contact surface is not easy to hot-dip galvanize, resulting in an unsatisfactory surface treatment effect; secondly, during the use of the device, the hanging frame is located above the hot-dip galvanizing tank, which hinders the movement of the metal stamping part and is not convenient to use, and needs to be improved. In view of this, we propose a surface treatment device for metal stamping parts. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the problems mentioned above, such as the inconvenience of hot-dip galvanizing the bonding surface between the middle clamping plate and the metal stamping part, resulting in poor surface treatment, and the inconvenience of using the hanging frame located above the hot-dip galvanizing tank, which hinders the movement of the metal stamping part, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a surface treatment device for metal stamping parts, which facilitates the replacement of the clamping and contacting surface with the metal stamping parts, improves the surface hot-dip galvanizing effect, facilitates the adjustment of the position of the mesh plate, avoids obstructing the movement of the metal stamping parts, and is more convenient to use.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A surface treatment device for metal stamping parts includes a hot-dip galvanizing tank. Hydraulic cylinders are mounted on both side walls of the tank. A movable plate is mounted on the top of each hydraulic cylinder. A movable seat is mounted on the side wall of each movable plate. A clamping assembly is located inside the movable seat. The clamping assembly includes a motor located on top of the movable seat. A rotating shaft is mounted at the output end of the motor. A crown gear is mounted on the bottom of the outer circumference of the rotating shaft. Four bevel gears mesh with the top of the crown gear. Lead screws are mounted on the side walls of each of the four bevel gears. Slider blocks are threaded onto the outer circumference of each of the four lead screws. Connecting rods are mounted at the bottom of each of the four sliders. Clamping plates are mounted at the bottom of each of the four connecting rods. A suspension assembly is mounted on the side wall of the hot-dip galvanizing tank. The hydraulic cylinders and motor are electrically connected to an external power source. The connecting rods have a certain length to prevent molten metal from the hot-dip galvanizing tank from entering the movable seat and causing damage to the motor or obstructing the rotation of the bevel gears.

[0012] In a preferred embodiment of the surface treatment device for metal stamping parts according to this utility model, the suspension assembly includes two cylinders. Each cylinder's output end is equipped with a movable block. Each movable block's inner cavity sidewall is slidably connected to a mounting block. Each movable block's sidewall is threaded with bolts. Each mounting block's top is equipped with a mesh plate. One mesh plate's sidewall has a retaining plate, and the other mesh plate's sidewall has a retaining groove. The cylinders are electrically connected to an external power source. The bolts are screwed into the movable blocks for easy disassembly and assembly of the mounting blocks, thus facilitating the disassembly and assembly of the mesh plates for cleaning and preventing clogging of the mesh.

[0013] In a preferred embodiment of the surface treatment device for metal stamping parts according to this utility model, the thread directions of the outer circumferences of the two lead screws with opposite directions are the same, and the positions of the four clamping plates are matched.

[0014] In a preferred embodiment of the surface treatment device for metal stamping parts according to this utility model, four through slots are provided on the top of the movable seat, the positions of the through slots are matched with the positions of the sliders, and the lead screw is rotatably connected to the side wall of the through slots. The through slots facilitate the dissipation of hot air inside the hot-dip galvanizing tank after the movable seat is lowered, preventing pressure changes from affecting the use.

[0015] In a preferred embodiment of the surface treatment device for metal stamping parts according to the present invention, the slider is provided with limiting blocks on both sides, and the through groove is provided with limiting grooves on both sides. The size and position of the limiting blocks match the size and position of the limiting grooves.

[0016] In a preferred embodiment of the surface treatment device for metal stamping parts according to this utility model, the size of the mounting block matches the size of the inner cavity of the moving block, and the size and position of the card plate match the size and position of the card slot.

[0017] As a preferred embodiment of the surface treatment device for metal stamping parts of this utility model, the bottom of the hydraulic cylinder is provided with a first fixing plate located on the side wall of the hot-dip galvanizing tank, and the bottom of the pneumatic cylinder is provided with a second fixing plate located on the side wall of the hot-dip galvanizing tank.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This surface treatment device for metal stampings works by turning on a motor to rotate a shaft, which in turn rotates a crown gear and drives two transverse bevel gears to rotate. This causes two transverse lead screws to rotate simultaneously, moving two sliders inward. This allows a connecting rod to drive clamping plates to hold the metal stampings. Turning on a hydraulic cylinder moves a moving plate downward, which in turn moves the moving seat and the metal stampings downward into the hot-dip galvanizing tank for hot-dip galvanizing surface treatment. Controlling a motor causes the crown gear to rotate in the opposite direction, which in turn rotates two longitudinal bevel gears. This causes two longitudinal lead screws to rotate simultaneously, driving two longitudinal clamping plates to hold the metal stampings. The two transverse clamping plates disengage from the metal stampings, facilitating the replacement of the clamping surfaces and improving the hot-dip galvanizing effect.

[0021] This surface treatment device for metal stampings uses an air cylinder to move two moving blocks outward, thereby moving two mesh plates outward simultaneously. A hydraulic cylinder is controlled to move the metal stampings upward, preventing obstruction. The air cylinder then moves the two mesh plates inward simultaneously. A clamping assembly places the metal stampings on top of the mesh plates. A clamping plate is inserted into a slot for easy assembly, preventing the metal stampings from being squeezed under gravity and causing the two mesh plates to tilt. Excess coating on the surface of the metal stampings drips into the hot-dip galvanizing tank. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model is described in detail with reference to the schematic diagrams.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a surface treatment device for metal stamping parts, including:

[0035] Please see Figures 1-5 This embodiment of a surface treatment device for metal stamping parts includes a hot-dip galvanizing tank 1. Hydraulic cylinders 2 are fixedly mounted on both side walls of the hot-dip galvanizing tank 1. Movable plates 3 are fixedly mounted on the top of each hydraulic cylinder 2. Movable seats 4 are welded to the side walls of the movable plates 3. A clamping assembly 5 is rotatably connected inside the movable seat 4. The clamping assembly 5 includes a motor 501 located on top of the movable seat 4. A rotating shaft 502 is fixedly mounted at the output end of the motor 501. A crown gear 503 is fixedly mounted on the bottom of the outer circumference of the rotating shaft 502. Four bevel gears 504 mesh with the top of the crown gear 503. Lead screws 505 are fixedly mounted on the side walls of each of the four bevel gears 504. Slider blocks 506 are threadedly connected to the outer circumference of each of the four lead screws 505. Connecting rods 507 are fixedly mounted on the bottom of each of the four sliders 506. Clamping plates 508 are welded to the bottom of each of the four connecting rods 507. A suspension assembly 6 is fixedly mounted on the side wall of the hot-dip galvanizing tank 1. The device also includes hydraulic cylinders 2 and a motor 501. Electrically connected to an external power source, the motor 501 drives the rotating shaft 502 to rotate, which in turn rotates the crown gear 503, causing the two transverse bevel gears 504 to rotate. This, in turn, causes the two transverse lead screws 505 to rotate simultaneously, moving the two sliders 506 inward. This facilitates the connecting rod 507 driving the clamping plate 508 to clamp the metal stamping. The hydraulic cylinder 2 is opened, causing the moving plate 3 to move downward, which in turn causes the moving seat 4 to move the metal stamping downward into the hot-dip galvanizing tank 1 for hot-dip galvanizing surface treatment. The motor 501 is controlled to rotate the crown gear 503 in the opposite direction, causing the two longitudinal bevel gears 504 to rotate. This causes the two longitudinal lead screws 505 to rotate simultaneously, driving the two longitudinal clamping plates 508 to clamp the metal stamping. The two transverse clamping plates 508 disengage from the metal stamping, facilitating the replacement of the clamping and contact surfaces with the metal stamping and improving the surface hot-dip galvanizing effect.

[0036] It is worth noting that, in order to prevent the movement of the metal stamping part from being obstructed by the suspension assembly, the suspension assembly 6 specifically includes two cylinders 601. Each cylinder 601 has a moving block 602 fixedly mounted at its output end. Each moving block 602 has a mounting block 603 slidably connected to its inner cavity sidewall. Each moving block 602 has a bolt 604 threadedly connected to its sidewall. Each mounting block 603 has a mesh plate 605 welded to its top. One mesh plate 605 has a retaining plate 606 fixedly mounted on its sidewall, and the other mesh plate 605 has a retaining groove 607 on its sidewall. The cylinders 601 are electrically connected to an external power source. The connection is achieved by opening cylinder 601 to move two moving blocks 602 outward, thereby causing two mesh plates 605 to move outward simultaneously. The hydraulic cylinder 2 is controlled to move the metal stamping part upward to avoid obstruction. By opening cylinder 601, the two mesh plates 605 are moved inward simultaneously. The clamping assembly 5 places the metal stamping part on top of the mesh plate 605. The clamping plate 606 is inserted into the clamping slot 607 for easy splicing, preventing the metal stamping part from being squeezed under gravity and causing the two mesh plates 605 to tilt. Excess coating on the surface of the metal stamping part drips into the hot-dip galvanizing tank 1.

[0037] Next, in order to control the movement direction of the two sliders 506 with opposite directions, specifically, the threads on the outer circumference of the two lead screws 505 with opposite directions are in the same direction, and the positions of the four clamps 508 are matched. By using the two opposite lead screws 505 with the same thread direction, it is convenient to make the two lead screws 505 with opposite directions rotate in opposite directions at the same time when the crown gear 503 rotates, so that the two sliders 506 with opposite directions can move inward or outward at the same time.

[0038] Meanwhile, in order to make the slider 506 move more smoothly, specifically, four through slots are opened on the top of the moving seat 4. The position of the through slots matches the position of the slider 506. The lead screw 505 is rotatably connected to the side wall of the through slot. The rotatable connection between the lead screw 505 and the side wall of the through slot improves stability and prevents the lead screw 505 from falling off.

[0039] Furthermore, in order to limit the movement of the slider 506, specifically, limit blocks 509 are fixed on both side walls of the slider 506, and limit grooves 510 are opened on both side walls of the through groove. The size and position of the limit blocks 509 match the size and position of the limit grooves 510. By using the limit blocks 509 that match the size and position of the limit grooves 510, it is easy to limit the movement of the slider 506 and prevent the slider 506 from rotating with the lead screw 505.

[0040] It is worth noting that, in order to ensure the stable suspension of the metal stamping parts, specifically, the size of the mounting block 603 matches the size of the inner cavity of the moving block 602, and the size and position of the clamping plate 606 match the size and position of the clamping slot 607. By using the clamping plate 606, which matches the size and position of the clamping slot 607, it is easier to make the splicing of the two mesh plates 605 more stable and avoid the metal stamping parts from slipping due to shaking.

[0041] Finally, to improve stability, specifically, the bottom of the hydraulic cylinder 2 is fixed with a first fixing plate 7 located on the side wall of the hot-dip galvanizing tank 1, and the bottom of the cylinder 601 is fixed with a second fixing plate 8 located on the side wall of the hot-dip galvanizing tank 1. The stability of the hydraulic cylinder 2 is improved by the first fixing plate 7, and the stability of the cylinder 601 is improved by the second fixing plate 8.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] Hydraulic cylinder 2: HS01-210L;

[0045] Motor 501: Y90S-2;

[0047] Combination Figures 1-5 The surface treatment device for metal stamping parts according to this embodiment is used in the following specific process:

[0048] 1: When this device is needed for surface treatment of metal stamping parts, start the motor 501 to make the rotating shaft 502 rotate, which drives the crown gear 503 to rotate, thereby causing the two transverse bevel gears 504 to rotate, which in turn drives the two transverse lead screws 505 to rotate simultaneously. Then, the two sliders 506 move inward, which drives the clamping plate 508 to clamp the metal stamping part. Start the hydraulic cylinder 2 to drive the metal stamping part to move downward into the hot-dip galvanizing tank 1 for hot-dip galvanizing treatment. Control the motor 501 to rotate in the opposite direction so that the two longitudinal clamping plates 508 clamp the metal stamping part and change the clamping and bonding surface.

Start cylinder 601 to merge the two mesh plates 605. Insert clamping plate 606 into the clamping slot 607. Control clamping assembly 5 to place the metal stamping part on top of mesh plate 605 for hanging and draining excess coating.
