Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, and specifically to a forging conveying assembly. Background Technology
[0002] The forging process mainly includes three stages: heating, forging, and heat treatment. During the alternation of these three stages, transfer equipment is needed to transfer the forging to the next stage.
[0003] The current method of transferring forgings from the heating furnace to the forging equipment usually involves using an overhead crane to lift the forgings. However, this method has the following problems: First, when using an overhead crane, the crane mainly moves in a single linear motion. When the installation positions of the various pieces of equipment are not in a straight line, the forgings cannot be transferred directly. It requires remote operation by the operator to apply force to rotate the forgings and adjust their orientation. This operation has a low safety factor, low production efficiency, and high heat loss. Second, the stability and safety of the overhead crane when lifting and transferring forgings are poor, especially when the travel distance and travel time are long. Utility Model Content
[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a forging conveying assembly that allows forgings to turn at multiple angles, thereby improving the safety and stability of the conveying process.
[0005] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a forging conveying assembly, comprising:
[0006] A heating furnace, used to heat forgings;
[0007] A forging turning fixture is set on one side of the furnace opening of the heating furnace to place the forging and adjust its orientation;
[0008] A hoisting mechanism is provided between the heating furnace and the forging turning fixture to transfer the forgings on the heating furnace to the forging turning fixture;
[0009] A forging machine for forging workpieces in a vertical direction; a forging turning fixture is located on the feeding side of the forging machine; the feeding direction of the forging machine is perpendicular to the conveying direction of the hoisting mechanism.
[0010] A guiding mechanism is disposed between the forging turning fixture and the forging machine, wherein the forging turning fixture moves along the guiding mechanism to convey the forging to the forging machine;
[0011] A clamping mechanism is provided on the discharge side of the forging machine to clamp the forging and cooperate with the forging turning tool to transfer the forging to the forging machine.
[0012] A preferred technical solution is that the forging turning tooling includes:
[0013] Base;
[0014] A support plate is disposed above the base;
[0015] A linear drive mechanism is disposed between the base and the support plate and drives the support plate to move in the vertical direction;
[0016] A guide post is disposed on the base and slidably connected to the support plate; the linear drive mechanism drives the support plate to perform linear reciprocating motion along the guide post.
[0017] A forging limiting seat, used to place forgings, is located above the support plate;
[0018] A rotary drive mechanism is disposed between the support plate and the forging limiting seat and drives the forging limiting seat to rotate;
[0019] The rotation axis of the forging limiting seat is in the same direction as the vertical direction.
[0020] The preferred technical solution is that the forging limiting seat has a C-shaped structure, including a base plate and two limiting plates connected to the base plate, with the two limiting plates arranged opposite to each other along the width direction of the base plate; the base plate has two limiting seat end faces arranged opposite to each other along the length direction of the base plate.
[0021] A preferred technical solution is that the hoisting mechanism includes a crossbeam and a traveling crane slidably fixed to the crossbeam. The crossbeam is located above the heating furnace. The traveling crane lifts the forging in a vertical direction. The traveling crane moves along the crossbeam to transfer the forging from the heating furnace to the forging turning fixture.
[0022] The preferred technical solution is that the guiding mechanism consists of two parallel guide rails, and the forging turning tool moves along the guide rails.
[0023] A preferred technical solution is that the clamping mechanism includes a slide groove and two clamping members slidably connected to the slide groove. The two clamping members are arranged opposite to each other and move towards or away from each other along the slide groove to clamp forgings of different sizes.
[0024] A preferred technical solution is that the slide is disposed between two columns and moves in a vertical direction, and the columns are disposed on the guide rail and move closer to or further away from the forging machine along the guide rail.
[0025] The advantages and beneficial effects of this utility model are as follows: the setting of the forging turning fixture enables the forging to rotate around the vertical direction, increasing the diversity of the forging conveying path; the cooperation between the forging turning fixture and the hoisting mechanism completes the 90-degree turn of the forging, so as to realize the conveying of the forging between the heating furnace and the forging machine, improving the safety and stability of the conveying; the cooperation of the forging turning fixture, the clamping mechanism and the guiding mechanism completes the 180-degree turn of the forging, which facilitates the forging of both ends of the forging, and the forging is more comprehensive.

[0034] like Figure 1-4 As shown, an embodiment of a forging conveying assembly includes:
[0035] Heating furnace 1 is used to heat the forgings;
[0036] Forging turning fixture 2 is set on one side of the furnace opening 11 of the heating furnace 1 to place the forging and adjust the orientation of the forging;
[0037] The hoisting mechanism 3 is located between the heating furnace 1 and the forging turning fixture 2, and is used to transfer the forgings on the heating furnace 1 to the forging turning fixture 2;
[0038] Forging machine 4 forging workpieces vertically; forging turning fixture 2 is set on the feeding side 41 of forging machine 4; the feeding direction of forging machine 4 is perpendicular to the conveying direction of hoisting mechanism 3.
[0039] The guide mechanism 5 is located between the forging turning fixture 2 and the forging machine 4. The forging turning fixture 2 moves along the guide mechanism 5 to convey the forging to the forging machine 4.
[0040] The clamping mechanism 6 is located on the discharge side 42 of the forging machine 4 to clamp the forging and cooperate with the forging turning tool 2 to transfer the forging to the forging machine 4.
[0041] In this embodiment, the forging conveying assembly includes two conveying sections. The first conveying section uses a hoisting mechanism 3 to transfer the forging from the heating furnace 1 to the forging turning fixture 2. The second conveying section uses the cooperation of the forging turning fixture 2, the guiding mechanism 5, and the clamping mechanism 6 to transfer the forging from the forging turning fixture 2 to the forging machine 4. Compared to the method of using the hoisting mechanism 3 for the entire conveying process, the forging turning fixture 2 works in conjunction with the hoisting mechanism 3 to complete the conveying, reducing the conveying distance and time of the hoisting mechanism 3, and improving the stability and safety of the conveying.
[0042] Due to site constraints, large equipment such as the forging machine 4, heating furnace 1, and clamping mechanism 6 may not be aligned during installation. Taking shaft forgings as an example, when the forging machine 4 and heating furnace 1 are aligned (i.e., the furnace opening 11 of the heating furnace 1 faces the feed side 41 of the forging machine 4), the hoisting mechanism 3 directly transfers the forging from the heating furnace 1 to the forging machine 4. However, when the forging machine 4 and heating furnace 1 are not aligned (i.e., the furnace opening 11 of the heating furnace 1 and the feed side 41 of the forging machine 4 are not opposite each other), the forging cannot move in a single direction to the feed side 41 of the forging machine 4 after exiting the heating furnace 1. The orientation of the forging needs to be adjusted to facilitate its entry into the forging machine 4. The forging turning fixture 2, in conjunction with the hoisting mechanism 3, changes the orientation of the forging, thereby enabling its transfer from the heating furnace 1 to the forging machine 4.
[0043] like Figure 1-2 As shown, the feeding direction of the forging machine 4 is perpendicular to the conveying direction of the hoisting mechanism 3; therefore, the forging turning fixture 2 adjusts the forging by 90° to complete the forging turning in order to cooperate with the conveying. Furthermore, the forging rotates in a plane perpendicular to the vertical direction, that is, the rotation axis of the forging is in the same direction as the vertical direction.
[0044] like Figure 1-3 As shown, in another preferred embodiment, the forging turning tool 2 includes:
[0045] Base 21;
[0046] Support plate 23 is disposed above base 21;
[0047] A linear drive mechanism 22 is disposed between the base 21 and the support plate 23 and drives the support plate 23 to move in the vertical direction;
[0048] Guide column 24 is set on base 21 and slidably connected to support plate 23; linear drive mechanism 22 drives support plate 23 to perform linear reciprocating motion along guide column 24;
[0049] Forging limiting seat 26, used to place forgings, is located above support plate 23;
[0050] A rotary drive mechanism 25 is disposed between the support plate 23 and the forging limiting seat 26 and drives the forging limiting seat 26 to rotate; the rotation axis of the forging limiting seat 26 is in the same direction as the vertical direction.
[0051] The height of the forging limiting seat 26 is adjusted by the linear drive mechanism 22 so that the forging limiting seat 26 is at the same height as the upper surface of the anvil 44 of the forging machine 4 or is located between the anvil block 43 and the anvil 44 of the forging machine 4, so that the clamping mechanism 6 can clamp the forging on the forging limiting seat 26. In this embodiment, the forging machine 4 includes anvil block 43 and anvil 44. The forging is placed on the upper surface of the anvil 44. The anvil block 43 moves back and forth toward and away from the anvil 44 under the action of hydraulic drive to achieve forging.
[0052] In this embodiment, the forging turning fixture 2 and the heating furnace 1 are located on base surfaces at different heights. Therefore, the linear drive mechanism 22 adjusts the height of the forging limit seat 26 so that it can be raised when in use and lowered when idle.
[0053] The rotary drive mechanism 25 is configured to adjust the orientation of the forging on the forging limit seat 26.
[0054] In this embodiment, the linear drive mechanism 22 is a hydraulic cylinder, which drives the forging limit seat 26 to rise and fall; the rotary drive mechanism 25 is a hydraulic motor, which controls the rotation of the forging limit seat 26.
[0055] like Figure 1-3 As shown, in another preferred embodiment, the forging limiting seat 26 has a C-shaped structure, including a base plate 261 and two limiting plates 262 connected to the base plate 261. The two limiting plates 262 are arranged opposite to each other along the width direction of the base plate 261. The base plate 261 has two limiting seat end faces 263 arranged opposite to each other along the length direction of the base plate 261.
[0056] The limiting plate 262 is designed to confine the forging between the two limiting plates 262. Taking a shaft forging as an example, the length direction of the shaft forging is in the same direction as the length direction of the base plate 261.
[0057] Furthermore, the forging turning fixture 2 adjusts the orientation of the forging on the forging limiting seat 26 via the rotary drive mechanism 25. The forging limiting seat 26 rotates with the drive of the rotary drive mechanism 25, having a first state and a second state. When the forging limiting seat 26 is in the first state, the end face 263 of the limiting seat faces the furnace opening 11 of the heating furnace 1. When the forging limiting seat 26 is in the second state, the end face 263 of the limiting seat faces the forging machine 4. The rotary drive mechanism 25 adjusts the forging limiting seat 26 between the first and second states, facilitating the transfer of the forging between the heating furnace 1 and the forging machine 4.
[0058] like Figure 1-2 As shown, in another preferred embodiment, the hoisting mechanism 3 includes a crossbeam 31 and a trolley 32 slidably fixed to the crossbeam 31. The crossbeam 31 is located above the heating furnace 1. The trolley 32 lifts the forging in the vertical direction and moves along the crossbeam 31 to transfer the forging from the heating furnace 1 to the forging turning fixture 2.
[0059] The forging is transferred from the heating furnace 1 to the forging turning fixture 2 by means of the hoisting mechanism 3.
[0060] In this embodiment, the number of cranes 32 is set to two to improve the stability of lifting.
[0061] In this embodiment, a wire ring is provided below the overhead crane 32. The forging is fitted onto the wire ring, and after being lifted vertically for a certain distance, the overhead crane 32 moves along the crossbeam 31 to move the forging directly above the forging turning fixture 2. Then, the overhead crane 32 descends vertically to place the forging on the forging limiting seat 26. Furthermore, the lifting point of the forging can be hooked by a hook below the overhead crane 32 to achieve forging transfer.
[0062] Furthermore, a track for the crane 32 to run on is provided on the crossbeam 31, and the length of the track extends in the same direction as the conveying direction of the hoisting mechanism 3.
[0063] like Figure 1-2 As shown, in another preferred embodiment, the guide mechanism 5 consists of two parallel guide rails, and the forging turning tool 2 moves along the guide rails.
[0064] The guide mechanism 5 restricts the movement direction of the forging turning tool 2 in order to transfer the forging to the forging machine 4.
[0065] In this embodiment, the forging steering fixture 2 is connected to a pneumatic cylinder or a hydraulic cylinder and moves along a guide rail under the drive of the pneumatic cylinder or the hydraulic cylinder. Furthermore, in this embodiment, the base 21 of the forging steering fixture 2 is connected to rollers, which are arranged on opposite sides of the base 21, with at least two rollers on each side of the base 21; the rollers are disposed within the guide rail and move along the guide rail. Furthermore, the rollers are connected to the base 21 via bearings.
[0066] like Figure 1-2 As shown, in another preferred embodiment, the clamping mechanism 6 includes a slide groove 61 and two clamping members 62 slidably connected to the slide groove 61. The two clamping members 62 are arranged opposite to each other and move towards or away from each other along the slide groove 61 to clamp forgings of different sizes.
[0067] The clamping member 62 is slidably disposed in the slide groove 61. The clamping member 62 is connected to the cylinder or oil cylinder. The cylinder or oil cylinder drives the two clamping members 62 to move, and adjusts the distance between the two clamping members 62 to accommodate the clamping of forgings of different sizes.
[0068] like Figure 1-2 As shown, in another preferred embodiment, the slide 61 is disposed between the two columns 63 and moves in the vertical direction, and the columns 63 are disposed on the guide rail 64 and move closer to or further away from the forging machine 4 along the guide rail 64.
[0069] The column 63 and guide rail 64 are set up to adjust the vertical movement of the clamping member 62 and the distance between the clamping member 62 and the forging machine 4.
[0070] In this embodiment, the slide 61 is hydraulically driven to move vertically along the column 63; the column 63 is driven to move on the guide rail 64 by a cylinder or oil cylinder.
[0071] The clamping mechanism can move in three dimensions, and its motion principle is similar to that of a three-dimensional moving platform.
[0072] like Figure 1-4 As shown, the operation steps of this utility model are as follows:
[0073] Step 1: Adjust the position of the forging turning fixture 2, adjust the linear drive mechanism 22 so that the upper surface of the forging limiting seat 26 in the vertical direction is higher than the upper surface of the anvil 44 of the forging machine 4, and adjust the rotary drive mechanism 25 so that the limiting seat end face 263 of the forging limiting seat 26 faces the furnace opening 11 of the heating furnace 1.
[0074] Step 2: Start the overhead crane 32. The steel wire rings of the two overhead cranes 32 descend vertically to the forging and respectively loop over both ends of the forging. The overhead crane 32 lifts the forging to detach it from the heating furnace 1. Drive the overhead crane 32 to move along the crossbeam 31, so that the forging moves from above the heating furnace 1 to directly above the forging limiting seat 26. The overhead crane 32 descends and places the forging on the forging limiting seat 26.
[0075] Step 3: Adjust the rotary drive mechanism 25 so that the end face 263 of the limit seat is aligned with the feed side 41 of the forging machine 4, that is, the end face of the forging is aligned with the feed side 41 of the forging machine 4; this completes the first rotation of the forging.
[0076] Step 4: Drive the forging turning tool 2 to move along the guide mechanism 5 toward the forging machine 4, move the forging above the anvil 44 of the forging machine 4, and stop the movement of the forging turning tool 2;
[0077] Step 5: Adjust the height of the clamping member 62 (adjust the height so that the clamping member 62 can easily clamp the forging), drive the clamping mechanism 6 to move along the guide rail 64 toward the forging machine 4 so that the clamping member 62 can clamp the forging and then stop moving. The clamping member 62 clamps one end of the forging and places the forging on the forging machine 4. The forging turning fixture 2 moves away from the forging machine 4 along the guide mechanism 5. The forging turning fixture 2 moves to a position that does not interfere with the forging pressing of the forging and then stops moving.
[0078] Step 6: With one end of the forging held by the clamping mechanism 6, the forging machine 4 forges the forging.
[0079] Step 7: After the forging in Step 6 is completed, drive the forging turning fixture 2 to move toward the forging machine 4. Clamping piece 62 clamps the forging and places it on the forging turning fixture 2. The forging turning fixture 2 rotates the forging 180° around the vertical direction; this is where the second turning is achieved.
[0080] Step 8: Clamping member 62 clamps the other end of the forging, and the forging machine 4 is started to forge the forging.
[0081] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
