Description

Technical Field

[0001] This invention relates to the field of forging machine technology, and in particular to a clamping device for a forging table of a forging machine. Background Technology

[0002] When forging metals, forging machines typically require a forging table. The calcined metal material is placed on the forging table, and methods such as hammering are used to transform the ductile metal material into a workpiece with a certain shape and size, thereby changing its physical properties.

[0003] However, during the forging process, in order to ensure the stability of the metal material's position during forging, clamping tools are usually used to hold it before hammering. In the existing technology, to ensure worker safety, robotic arms are usually used to hold the metal material. The flexible robotic arm is used to flip and move the material during the forging process. Although this effectively ensures the clamping requirements during the forging process, the maintenance cost of the robotic arm is high, and it is easily affected by the high-temperature debris generated during forging. After a long time of gripping high-temperature metal, metal scrap will adhere to the gripper, which will eventually affect the gripping effect.

[0004] To address the aforementioned issues, we propose a clamping device for the forging table of a forging machine. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by providing a clamping device for a forging table of a forging machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for a forging table of a forging machine, comprising a frustum-shaped base, a forging table fixedly installed on the base, four rectangularly distributed uprights fixedly connected to the upper end of the base, lifting blocks slidably sleeved on each of the four uprights, the four lifting blocks being fixed sequentially by four connecting rods, hydraulic telescopic rods installed on both sides of the base, lifting plates fixedly connected to the telescopic ends of two of the hydraulic telescopic rods, the two lifting plates being fixedly connected to the connecting rods on the left and right sides respectively, and a limiting frame fixedly connected to the upper end of the base at the position between the forging table and the uprights, forming a slag pool between the limiting frame and the forging table;

[0007] Each of the four connecting rods is equipped with a clamping assembly, which is arranged in a rectangular shape. A clamping block cleaning mechanism is provided on the forging table at the corresponding position of each of the four clamping assemblies.

[0008] In the above-mentioned clamping device for forging table of forging machine, four connecting rods and four lifting blocks form a lifting frame, and a three-proof cloth cover is fixedly connected between the lifting frame and the limiting frame.

[0009] In the aforementioned clamping device for a forging table of a forging machine, the clamping assembly includes a mounting plate fixedly connected to the upper end of a connecting rod. A telescopic cylinder is fixedly mounted on the end of the mounting plate away from the forging table. The telescopic end of the telescopic cylinder passes through the mounting plate and is fixedly connected to a drive box. A drive shaft is rotatably connected to the inner wall of the drive box near the telescopic cylinder. A buffer box is fixedly connected to the end of the drive shaft away from the telescopic cylinder, passing through the drive box. The buffer box is open at the end away from the drive shaft. A movable plate is slidably connected inside the buffer box. Multiple evenly distributed springs are fixedly connected between the movable plate and the inner wall of the buffer box. A fixing strip is fixedly connected to the end of the movable plate away from the springs. A mounting frame is fixedly connected to the fixing strip by bolts. A clamping plate is fixedly connected to the end of the mounting frame away from the buffer box.

[0010] In the above-mentioned clamping device for forging table of forging machine, a worm gear is fixedly sleeved on the drive shaft and inside the drive box, a worm is rotatably connected between the upper and lower inner walls of the drive box, the worm meshes with the worm gear, and a first motor for driving the worm to rotate is fixedly installed at the upper end of the drive box.

[0011] In the above-mentioned clamping device for forging table of forging machine, the upper ends of the four uprights are all fixedly connected with limit caps.

[0012] In the aforementioned clamping device for a forging table of a forging machine, the four clamping block cleaning mechanisms include cleaning grooves formed on the outer walls of the forging table. The upper end of each cleaning groove is open. Two rotating shafts are rotatably connected between the inner walls of the two sides of the cleaning groove, and two pulleys are fixedly sleeved on each of the two rotating shafts. A transmission belt is sleeved between the two corresponding pulleys. A grinding belt is fixedly connected between the two transmission belts located in the same cleaning groove. A drive groove is formed on the outer walls of the forging table, and a second motor is fixedly installed in each drive groove. The four second motors drive the four rotating shafts located above to rotate.

[0013] In the above-mentioned clamping device for forging table of forging machine, each of the four cleaning grooves is fixedly connected with a support plate. The support plate is located between two vertically distributed rotating shafts and inside the grinding belt. The end of the support plate facing the outside of the drive groove is a smooth plane and is in close contact with the inside of the grinding belt.

[0014] In the aforementioned clamping device for a forging table of a forging machine, the bottom walls of the four cleaning tanks are all inclined slopes and are positioned towards the slag pool.

[0015] In the above-mentioned clamping device for forging table of forging machine, a slag extraction pipe is installed in the slag pool. One end of the slag extraction pipe is located in the slag pool, and the other end passes through the base and is connected to an industrial vacuum cleaner.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] 1. By setting up a lifting frame, a limiting frame, and a three-proof cloth cover, the lifting frame can drive the upper end of the three-proof cloth cover to move, so that the three-proof cloth cover can effectively block the outside of the forging table during forging work. As a result, the high-temperature waste slag generated during forging work on the forging table is not easy to splash out of the range of the three-proof cloth cover. It can be effectively blocked and collected into the slag pool formed by the limiting frame, which greatly improves the safety of forging work of the forging press.

[0018] 2. By setting four clamping components, each of which can work independently, the metal material on the forging table can be easily moved and clamped. Through worm gear transmission, the metal material can be effectively flipped. Moreover, the components are located in the drive box and will not be affected by debris and waste, resulting in a long service life and lower maintenance costs.

[0019] 3. The cleaning mechanism and cleaning tank not only save on the material used in the forging table, but also allow the waste slag and debris on the forging table to be easily pushed into the cleaning tank and fall smoothly into the slag pool for easy cleaning. After each clamping component has finished clamping the metal material, the clamping plates in each clamping component can be moved down into the corresponding cleaning tank by the retraction of the telescopic cylinder and the hydraulic telescopic rod. During the descent, the clamping plates come into contact with the outer surface of the high-speed rotating grinding belt in the cleaning tank, effectively removing the metal waste attached to the surface of the clamping plates. This ensures that the clamping plates can still effectively adhere to the material surface for clamping when used again.

[0020] In summary, this invention achieves lower maintenance costs and better performance while ensuring effective clamping and position adjustment of metal materials. Attached Figure Description

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] Reference Figures 1-10A clamping device for a forging table in a forging machine includes a frustum-shaped base 1, which is made of cast concrete. A forging table 2, made of cast iron, is fixedly installed on the base 1. Four rectangular uprights 3 are fixedly connected to the upper end of the base 1. Lifting blocks 5 are slidably sleeved on each of the four uprights 3. Limit caps 7 are fixedly connected to the upper ends of the four uprights 3 to limit the movable range of the lifting blocks 5. The four lifting blocks 5 are fixedly connected in sequence by four connecting rods 6. The four connecting rods 6 and the four lifting blocks 5 form a lifting frame to achieve synchronous lifting. Hydraulic telescopic rods 9 are installed on both sides of the base 1. Lifting plates 10 are fixedly connected to the telescopic ends of the two hydraulic telescopic rods 9. The two lifting plates 10 are fixedly connected to the connecting rods 6 on the left and right sides, respectively. When the two hydraulic telescopic rods 9 work synchronously, they can drive the lifting frame to lift. A limit frame 4 is fixedly connected to the upper end of the base 1, between the forging table 2 and the uprights 3. A slag pool is formed between the limit frame 4 and the forging table 2 to collect the slag and waste generated during forging. A three-proof cloth cover 8 is fixedly connected between the lifting frame and the limiting frame 4. The three-proof cloth cover 8 is a barrier-type structure made of three-proof cloth. The upper end can move with the lifting frame. So when the lifting frame moves above the forging table 2, the three-proof cloth cover 8 can effectively wrap the outside of the forging table 2. Then, the high-temperature waste slag generated during the forging work on the forging table 2 is not easy to splash out of the range of the three-proof cloth cover 8. It can be effectively blocked and collected into the slag pool, which greatly improves the safety of the forging operation of the forging press.

[0034] It should be noted that the three-proof fabric is made of black flame-retardant coated fabric (polyurethane coated base fabric), and the surface is treated with anti-adhesion. It can withstand the impact of instantaneous high temperature iron filings, and the tight structure prevents iron filings from penetrating. It also has the ability to prevent coolant and oil stains.

[0035] A slag extraction pipe is installed inside the slag collection tank. One end of the pipe is located inside the tank, and the other end passes through the base 1 and connects to an industrial vacuum cleaner. This industrial vacuum cleaner, a current technology, possesses strong negative pressure suction, capable of sucking up and collecting the waste slag and debris generated during forging, facilitating centralized recycling. Furthermore, the end of the slag extraction pipe inside the tank can be connected to a flexible hose, allowing workers to easily and completely remove the waste slag from the tank after forging operations.

[0036] Each of the four connecting rods 6 is equipped with a clamping component. The four clamping components are arranged in a rectangular shape and rise and fall synchronously with the lifting frame. The position and height can be adjusted by two hydraulic telescopic rods 9. The clamping assembly includes a mounting plate 11 fixedly connected to the upper end of the connecting rod 6. A telescopic cylinder 12 is fixedly mounted on the end of the mounting plate 11 away from the forging table 2. The telescopic end of the telescopic cylinder 12 passes through the mounting plate 11 and is fixedly connected to a drive box 13. A drive shaft 14 is rotatably connected to the inner wall of the drive box 13 near the telescopic cylinder 12. A buffer box 18 is fixedly connected to the end of the drive shaft 14 away from the telescopic cylinder 12, passing through the drive box 13. The end of the buffer box 18 away from the drive shaft 14 is open. A movable plate 19 is slidably connected inside the buffer box 18. Multiple evenly distributed springs 20 are fixedly connected between the movable plate 19 and the inner wall of the buffer box 18. A fixing strip 21 is fixedly connected to the end of the movable plate 19 away from the springs 20. A mounting frame 22 is fixedly connected to the fixing strip 21 by bolts. A clamping plate 23 is fixedly connected to the end of the mounting frame 22 away from the buffer box 18.

[0037] Specifically, once the four clamping components are moved above the forging table 2, the corresponding clamping plates 23 can be moved by the telescopic cylinders 12. When the left and right clamping plates 23 simultaneously contact the metal material, the metal material can be clamped in the left-right direction; when the front and rear clamping plates 23 simultaneously contact the metal material, the metal material can be clamped in the front-back direction; and when all four clamping plates 23 simultaneously contact the metal material, the metal material can be clamped in all four directions. The four telescopic cylinders 12 operate independently, easily enabling the movement and clamping of the metal material on the forging table 2.

[0038] Furthermore, during forging in the clamped state, the buffer box 18 and spring 20 are designed to allow the metal material being hammered to deform effectively, while preventing the generated force from directly affecting the telescopic cylinder 12 and protecting the normal use of the components.

[0039] A worm gear 15 is fixedly sleeved on the drive shaft 14 and inside the drive housing 13. A worm 16 is rotatably connected between the upper and lower inner walls of the drive housing 13. The worm 16 meshes with the worm gear 15. A first motor 17 is fixedly installed at the upper end of the drive housing 13 to drive the worm 16 to rotate. The first motor 17 can drive the worm gear 15 to rotate through the worm 16, thereby driving the drive shaft 14 to rotate. When the drive shaft 14 rotates, the buffer box 18 and the corresponding clamping plate 23 rotate at the same angle. The transmission between the worm gear 15 and the worm 16 has self-locking properties, so when rotated to a suitable angle, it can maintain a stable state.

[0040] Specifically, when the first motor 17 in the two corresponding clamping mechanisms (left / right or front / back) operates synchronously, the metal material can be flipped while in the clamping state. It should be noted that during flipping, it is necessary to ensure that the metal material has sufficient rotation space, that is, the clamped metal material needs to be moved to a suitable height by means of the hydraulic telescopic rod 9.

[0041] The forging table 2 is equipped with a clamping block cleaning mechanism at the corresponding positions of the four clamping components. The four clamping block cleaning mechanisms include cleaning grooves 24 opened on the outer walls of the forging table 2. The upper end of the cleaning grooves 24 is open. The bottom wall of the four cleaning grooves 24 is an inclined slope facing the slag pool. The cleaning grooves 24 not only save the material used in the forging table 2, but also allow the waste slag and debris on the forging table 2 to be easily pushed into the cleaning grooves 24, so that they can fall smoothly into the slag pool and facilitate cleaning.

[0042] Two rotating shafts 25, spaced vertically, are rotatably connected between the inner walls of both sides of the cleaning tank 24. Two pulleys are fixedly sleeved on each of the two rotating shafts 25, and a transmission belt 26 is sleeved between the two corresponding pulleys. A grinding belt 27 is fixedly connected between the two transmission belts 26 located in the same cleaning tank 24. Drive slots 28 are opened on the outer walls of the forging table 2. A second motor 29 is fixedly installed in each drive slot 28. The four second motors 29 drive the four rotating shafts 25 located above to rotate. The second motors 29 can drive the transmission belts 26 in the corresponding drive slots 28 to rotate, thereby driving the grinding belt 27 to rotate. The grinding belt 27 can perform a grinding function at high speed.

[0043] Specifically, after each clamping component completes the clamping of the metal material, the clamping plate 23 in each clamping component can be moved down into the corresponding cleaning groove 24 by the retraction of the telescopic cylinder 12 and the hydraulic telescopic rod 9. During the downward movement, it comes into contact with the outer surface of the high-speed rotating grinding belt 27 in the cleaning groove 24, thereby effectively removing the metal scraps attached to the surface of the clamping plate 23. This ensures that the clamping plate 23 can still effectively adhere to the material surface for clamping when used next time.

[0044] Each of the four cleaning slots 24 is fixedly connected with a support plate 30. The support plate 30 is located between two vertically distributed rotating shafts 25 and inside the polishing belt 27. The end of the support plate 30 facing the outside of the cleaning slot 24 is a smooth plane and is in close contact with the inside of the polishing belt 27. The setting of the support plate 30 can ensure that the polishing belt 27 can maintain contact with the clamping plate 23 when cleaning the clamping plate 23, thus ensuring the effectiveness of the cleaning work.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
