A forging surface treatment apparatus

Abstract

This utility model discloses a surface treatment device for forgings, including a powered roller conveyor, and further including: a gantry frame, a lifting unit located directly above the powered roller conveyor, and a peeling unit mounted on the lifting end of the lifting unit. The lifting unit includes a lifting frame, and the peeling unit includes a pair of peeling mechanisms spaced apart along the conveying direction of the powered roller conveyor. Each peeling mechanism includes a horizontally rotating drive shaft with its length direction perpendicular to the conveying direction of the powered roller conveyor, and several steel wire wheels spaced equally along the drive shaft and mounted on the drive shaft.

After water peeling by a spraying device, when the powered roller conveyor conveys the plate forging to the area below the peeling unit, the rotation of the drive shaft will drive several steel wire wheels to rotate, thereby removing the oxide scale on the upper surface. The steel wire wheels on the pair of drive shafts are staggered, thereby peeling the entire upper surface of the plate forging and removing the residual oxide scale.

Description

Technical Field

[0001] This utility model relates to the technical field of forging surface treatment, specifically to a forging surface treatment device. Background Technology

[0002] The core advantages of plate forgings lie in their ultra-high internal quality, excellent comprehensive mechanical properties (high strength, high toughness, high fatigue strength), good isotropy, and reliability. Conventional rolled metal sheets offer advantages such as high efficiency, low cost, wide size range, good surface quality, and strong production continuity. Therefore, plate forgings are mainly used in environments requiring high strength, high toughness, and high fatigue strength.

[0003] Plate forgings need to go through heating, upsetting, drawing, widening, and leveling. Finally, they are free forged or die forged according to the equipment to determine the final specifications. During the forging deformation process, the forging needs to be heated multiple times to maintain the temperature of the forging. During the forging process, an oxide layer will be generated on the surface, so the forged product needs to be de-oiled.

[0004] Water-based descaling is the most commonly used method for removing oxide scale from forgings. It is a highly efficient and environmentally friendly method for removing iron oxide scale from the surface of hot forgings. Its core principle is to utilize the impact force, rapid cooling effect, and penetration and peeling effect of high-pressure water to break down and remove the oxide scale. It can instantly remove more than 95% of the oxide scale from the surface of high-temperature forgings, and is particularly effective for strongly adhesive, multi-layered oxide scale. While removing the oxide scale, it does not damage the metal substrate.

[0005] Water-based descaling equipment typically includes a powered roller conveyor, a spraying device, and a protective housing to prevent oxide scale from splashing out. It can efficiently remove more than 95% of oxide scale. However, some oxide scale may still remain on the product surface, so a forging surface treatment device needs to be added after the discharge end of the spraying device. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue that some residual oxide scale remains unremoved during water-based peeling in the prior art.

[0007] To achieve the above objectives, this utility model provides a forging surface treatment device, including a powered roller conveyor, and further including: a gantry frame, a lifting unit mounted on the gantry frame and located directly above the powered roller conveyor, and a peeling unit mounted on the lifting end of the lifting unit; The lifting unit includes a lifting frame, and the peeling unit includes a pair of peeling mechanisms spaced apart along the conveying direction of the power roller conveyor. Each peeling mechanism includes a horizontally rotating drive shaft with its length direction perpendicular to the conveying direction of the power roller conveyor and several steel wire wheels spaced equally along the drive shaft and mounted on the drive shaft. The steel wire wheels in the two peeling mechanisms are staggered.

[0008] Preferably, the peeling mechanism includes a vertical mounting arm fixedly connected to the lifting frame and with its lower end axially connected to one end of the drive shaft, a first motor mounted on the mounting arm and with its output shaft drivingly connected to the drive shaft, a bearing detachably mounted on the end of the drive shaft away from the mounting arm, and a mounting mechanism mounted on the lifting frame and connected to the bearing.

[0009] Preferably, the installation mechanism includes a bearing seat fixedly sleeved on the outer ring of the bearing, a vertical first connecting arm fixedly connected to the bearing seat, and a vertical second connecting arm fixedly connected to the lifting frame. The upper end of the first connecting arm is detachably connected to the second connecting arm by a plurality of first mounting bolts.

[0010] Preferably, the drive shaft is recessed with a strip-shaped groove of the same length direction, the end of the strip-shaped groove away from the mounting arm is an open end, the end of the drive shaft near the mounting arm is fixedly fitted with a positioning sleeve, a plurality of wire wheels are spaced apart by a plurality of spacer sleeves, the inner wall of the spacer sleeve has a locking strip portion that engages with the strip-shaped groove, and the end of the drive shaft away from the mounting arm is detachably fitted with a limiting sleeve that contacts the spacer sleeve or the wire wheel by a second mounting bolt; The inner ring of the wire wheel is provided with a mounting groove, and the two ends of the locking strip are extended to be inserted into the mounting groove of the adjacent wire wheel.

[0011] Preferably, the lifting frame is equipped with at least three auxiliary shafts that are parallel to the drive shaft and spaced apart along the conveying direction of the power roller conveyor via a mounting frame. Both ends of the auxiliary shafts are axially connected to the mounting frame. Each drive shaft has auxiliary shafts on both sides, and each auxiliary shaft is fixedly fitted with a number of pressure rollers spaced apart.

[0012] Preferably, the lifting unit includes at least two X-shaped deformable frames spaced apart along the conveying direction of the power roller conveyor; The two ends of the X-shaped deformable frame away from the mounting arm are rotatably connected to the top of the gantry and the lifting frame respectively via a first hinge shaft. The two ends of the X-shaped deformable frame near the mounting arm are each equipped with a second hinge shaft that is slidably connected to the top of the gantry and the lifting frame along the drive shaft axis. The top of the gantry is equipped with a linear drive mechanism for moving the second hinge shaft at the upper end of the X-shaped deformable frame along the drive shaft axis.

[0013] Preferably, the linear drive mechanism includes a threaded rod arranged parallel to the drive shaft and connected to the gantry frame shaft at both ends, a connecting sleeve threaded onto the threaded rod and sleeved onto the corresponding second hinge shaft, and a second motor assembled on the gantry frame with its output shaft connected to one end of the threaded rod.

[0014] Preferably, the first motor is connected to the drive shaft via a synchronous belt and a pair of synchronous pulleys.

[0015] Preferably, a pair of auxiliary sleeves are detachably mounted on the drive shaft via a third mounting bolt, and the auxiliary sleeves respectively contact the two ends of the inner ring of the bearing.

[0016] According to the above technical solution, the surface treatment equipment for forgings provided by this utility model has the following beneficial effects during use: Firstly, after the water-based peeling process by the spraying equipment, the powered roller conveyor transports the plate forging to the bottom of the peeling unit. The rotation of the drive shaft drives several wire wheels to rotate, thereby removing the oxide scale on the upper surface. The wire wheels on a pair of drive shafts are staggered, thus peeling the entire upper surface of the plate forging and removing the residual oxide scale. Secondly, the spacing between the several wire wheels on each drive shaft increases the distance between adjacent wire wheels, reducing the probability of oxide scale getting stuck on the wire wheels and facilitating slag removal. Thirdly, when the thickness of the plate forgings that need to be de-scaled is different, the height of the lifting frame can be adjusted by the lifting unit, thereby driving the wire wheel to adjust the height. It is highly practical and can remove the oxide scale from the surface of plate forgings of different thicknesses.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

The lifting unit includes a lifting frame 2, and the peeling unit includes a pair of peeling mechanisms spaced apart along the conveying direction of the power roller conveyor. Each peeling mechanism includes a horizontally rotating drive shaft 3 whose length direction is perpendicular to the conveying direction of the power roller conveyor, and several steel wire wheels 4 spaced equally along the drive shaft 3 and mounted on the drive shaft 3. The steel wire wheels 4 are staggered in the two sets of peeling mechanisms.

[0022] In the above technical solution, the powered roller conveyor is an existing mature technology, so it is not shown in the figure. The powered roller conveyor includes a base frame and several horizontal conveying rollers with transmission connection, thereby conveying the plate forging. After the water-based descaling process by the spraying equipment, the powered roller conveyor transports the plate forging to the area below the descaling unit. The rotation of the drive shaft 3 drives several wire wheels 4 to rotate, thereby removing the oxide scale from the upper surface. The wire wheels 4 on a pair of drive shafts 3 are staggered, thus descaling the entire upper surface of the plate forging and removing all residual oxide scale. The spacing between the several wire wheels 4 on each drive shaft 3 increases the distance between adjacent wire wheels 4, reducing the probability of oxide scale getting stuck on the wire wheels 4, which is beneficial for slag removal. When the thickness of the plate forgings that need to be de-scaled is different, the height of the lifting frame 2 can be adjusted by the lifting unit, thereby driving the wire wheel 4 to adjust the height. It is highly practical and can remove the oxide scale from the surface of plate forgings of different thicknesses.

[0023] In a preferred embodiment of the present invention, the peeling mechanism includes a vertical mounting arm 5 fixedly connected to the lifting frame 2 and whose lower end is axially connected to one end of the drive shaft 3, a first motor 6 mounted on the mounting arm 5 and whose output shaft is drivenly connected to the drive shaft 3, a bearing 7 detachably mounted on the end of the drive shaft 3 away from the mounting arm 5, and a mounting mechanism mounted on the lifting frame 2 and connected to the bearing 7.

[0024] In the above technical solution, when the wire wheel 4 needs to be replaced, the bearing 7 away from the mounting arm 5 is disassembled, several wire wheels 4 are removed from the end of the drive shaft 3 away from the mounting arm 5, and a new wire wheel 4 is installed.

The upper end of the first connecting arm 9 is detachably connected to the second connecting arm 10 by a plurality of first mounting bolts.

[0026] In the above technical solution, by loosening and removing several first mounting bolts, the bearing housing 8, bearing 7 and first connecting arm 9 can slide along the axis of the drive shaft 3 and be removed from the end of the drive shaft 3 to replace the wire wheel 4 on the drive shaft 3; after the replacement is completed, the bearing 7 is then fitted onto the end of the drive shaft 3, and the first connecting arm 9 and the second connecting arm 10 are fixedly connected together by several first mounting bolts.

[0027] In a preferred embodiment of this utility model, a strip-shaped groove 11 of the same length direction is recessed on the drive shaft 3.

The inner ring of the wire wheel 4 is provided with a mounting groove 16, and the two ends of the locking strip 14 are extended to be inserted into the mounting groove 16 of the adjacent wire wheel 4.

[0028] In the above technical solution, the second mounting bolt is loosened and removed, the limiting sleeve 15 is removed, and then several spacer sleeves 13 and wire wheels 4 are removed from the end of the drive shaft 3 away from the mounting arm 5; several new wire wheels 4 and several removed spacer sleeves 13 are alternately placed on the drive shaft 3. The spacer sleeves 13 can quickly separate several wire wheels 4 at a fixed distance, improving the replacement efficiency. Then the limiting sleeve 15 is assembled by the second mounting bolt, and the replacement of wire wheels 4 is completed. The locking strip 14 is inserted into the strip groove 11 to prevent the spacer sleeve 13 from rotating relative to the drive shaft 3. The end of the locking strip 14 is also inserted into the mounting groove 16 of the adjacent wire wheel 4, so that the wire wheel 4 will not rotate relative to the drive shaft 3.

[0029] In a preferred embodiment of this utility model, at least three auxiliary shafts 18 are mounted on the lifting frame 2 via mounting brackets 17.

The top of the gantry frame 1 is equipped with a linear drive mechanism for driving the second hinge shaft at the upper end of the X-shaped deformable frame 20 to move along the axis of the drive shaft 3.

[0032] In the above technical solution, the X-shaped deformable frame 20 generally consists of rotating arms that are hinged together in the middle. The linear drive mechanism drives the upper end of the X-shaped deformable frame 20 to slide through the second hinge shaft, which can drive the shape of the X-shaped deformable frame 20 to change, thereby driving the lifting frame 2 to rise and fall.

[0033] In a preferred embodiment of the present invention, the linear drive mechanism includes a threaded rod 21 arranged parallel to the drive shaft 3 and both ends of which are axially connected to the gantry frame 1, a connecting sleeve 22 threadedly sleeved on the threaded rod 21 and sleeved on the corresponding second hinge shaft, and a second motor 23 assembled on the gantry frame 1 and whose output shaft is connected to one end of the threaded rod 21.
