Description

Technical Field

[0001] This application relates to the technical field of forging flash removal, and in particular to a forging flash removal device. Background Technology

[0002] In the field of metal processing, forging is a core process for mass-producing high-performance metal components. Forging involves plastically deforming metal billets using forging machinery to obtain forgings. While its precision is limited, it offers high processing efficiency and preserves the internal flow lines of the metal. Forging imparts superior mechanical properties to the workpiece, making it suitable for scenarios where mechanical performance and efficiency are paramount. For example, forgings are typically used in the automotive industry for variable gear ratio racks. These racks are generally long and narrow. During forging, the metal billet is compressed, causing excess material to overflow and form flash. This flash is distributed along the length of the rack on both sides. After forging, the flash needs to be removed to ensure the precision and quality of the forging. Currently, flash removal for variable gear ratio racks mainly relies on milling or grinding, which has low efficiency, hinders the overall production process, and cannot meet the demands of mass forging. Summary of the Invention

[0003] To facilitate the removal of flash, this application provides a flash removal device for forgings.

[0004] The forging flash removal device provided in this application adopts the following technical solution: A forging flash removal device, comprising: Mounting base; The support base is used to place the forgings, and it is slidably connected to the mounting base and can be reset after sliding. A limiting device is used to limit the position of the forging and is installed on the mounting base; The cutter is mounted on the mounting base; and The pressing device, located on one side of the bearing seat, is used to press the forging towards the cutting blade to remove the flash of the forging.

[0005] By adopting the above technical solution, after the forging is placed on the support, the forging is limited by the limiting device, and then the forging is pressed by the pressing device to move the forging towards the cutting blade, and the cutting blade will remove the flash on the forging.

[0006] Preferably, the mounting base has a sliding groove, and the bearing seat is slidably connected to the sliding groove; a return spring is provided in the sliding groove, and the two ends of the return spring are respectively connected to the mounting base and the bearing seat.

[0007] By adopting the above technical solution, the elastic deformation capability of the return spring can be used to ensure that the bearing seat can be reset after movement and that the movement of the bearing seat is reliable.

[0008] Preferably, the return spring is a nitrogen spring.

[0009] By adopting the above technical solution, the nitrogen spring ensures reliable support and constant support force for the forging regardless of the position of the bearing seat. Since the forging is located between the pressing device and the bearing seat when the pressing device presses it, it bears forces from both. This stress may cause internal stress concentration or even structural deformation. The nitrogen spring provided in this application ensures balanced force on the forging, thus preventing structural damage.

[0010] Preferably, a cooling cavity is formed between the slide groove and the return spring, and the mounting base has an air inlet and an air outlet communicating with the cooling cavity.

[0011] By adopting the above technical solution, cold air is introduced into the air inlet, and the cold air will enter the cooling chamber and carry away the heat generated when the nitrogen spring is working. The heat will then be discharged from the air outlet.

[0012] Preferably, the cutter includes a mounting strip connected to the mounting base, the mounting strip having a cutting edge that extends along the length of the mounting strip.

[0013] By adopting the above technical solution, after the forging is placed on the bearing seat along the length of the mounting strip, all the flash on the forging can be easily removed in one go using the blade.

[0014] Preferably, the blade has a first end and a second end opposite to each other in the length direction of the mounting strip, and the upper end face of the blade is formed as a cutting surface, which gradually slopes downward from the first end to the second end.

[0015] By adopting the above technical solution, the inclined cutting surface allows the blade to gradually remove the flash, thus controlling the contact area between the blade and the flash to a small range. This design facilitates the removal of flash and prevents the blade from cracking.

[0016] Preferably, a waste material bearing portion is formed on the side of the blade on the mounting strip.

[0017] By adopting the above technical solution, the burrs cut off by the blade will accumulate on the waste support for cleaning.

[0018] Preferably, the mounting base is provided with a sliding column, a pressing head is slidably connected to the sliding column, and a pressing spring is also sleeved on the sliding column. The two ends of the pressing spring are respectively connected to the mounting base and the pressing head. The pressing head can apply a force to the forging in the direction of the length of the mounting strip under the action of the pressing spring.

[0019] By adopting the above technical solution, during the process of the forging being cut off by the blade, a force is applied to the forging toward the compression spring, causing the forging to move toward the compression spring. The compression spring will be compressed, and at this time the cutting direction of the blade on the flash is no longer vertical but oblique. This design can facilitate the removal of flash. After the force is applied, the compression spring will extend, causing the compression head to move away from the compression head on the forging, and the forging will return to its original position.

[0020] Preferably, the limiting device includes a limiting block disposed on the mounting base, and at least two limiting blocks are provided, wherein the two limiting blocks are respectively located on both sides of the forging.

[0021] By adopting the above technical solution, two limiting blocks can be used to limit the position of the forging and guide its movement.

[0022] Preferably, the pressing device is located on a movable seat on one side of the mounting base, the movable seat is detachably connected to the pressing mold, and the movable seat is also provided with an air nozzle facing the pressing mold.

[0023] By adopting the above technical solution, after the flash is removed, the flash may adhere to the pressing mold. The flash on the pressing mold can be blown away using an air nozzle.

[0024] In summary, the present invention has at least one of the following beneficial technical effects: 1. In this application, after the forging is placed on the support, the forging is limited by a limiting device, and then the forging is pressed by a pressing device to move the forging toward the cutting blade, and the cutting blade will remove the flash on the forging. 2. The nitrogen spring ensures reliable support and constant support force for the forging regardless of the position of the support seat. When the pressing device presses the forging, the forging is located between the pressing device and the support seat, and it bears forces from both. This stress can lead to internal stress concentration or even structural deformation. The nitrogen spring in this application ensures balanced force on the forging, thus preventing structural damage. 3. After the forging is placed on the support base along the length of the mounting strip, the inclined cutting surface allows the blade to gradually remove the flash during movement. This keeps the contact area between the blade and the flash small, facilitating flash removal and preventing blade breakage. Furthermore, by applying a force towards the compression spring, the forging moves towards the spring, compressing it. This changes the cutting direction of the blade from vertical to oblique, further simplifying flash removal. After the force is applied, the compression spring extends, causing the pressing head to move away from the pressing head, and the forging returns to its original position.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] This application discloses a flash removal device for forgings. It is used to facilitate the removal of flash. In this embodiment, flash removal of a variable transmission ratio rack is taken as an example. (Refer to...) Figure 1 The variable transmission ratio rack includes a shaft a, on which a rack portion b and multiple abutment portions c are formed. Flash is generally formed on both sides of the rack portion b.

[0030] Reference Figure 2 and Figure 3 The forging flash removal equipment includes a mounting base 1, which has a slide groove 11. A support seat 2 for placing a variable transmission ratio rack is slidably connected to the slide groove 11. Specifically, in conjunction with... Figure 3 The upper end of the bearing seat 2 has an arc-shaped bearing groove 21. After the abutment part c of the variable transmission ratio rack is placed into the arc-shaped bearing groove 21, the shaft a will fit against the arc-shaped bearing groove 21. A return spring 3 is provided in the slide groove 11. The two ends of the return spring 3 are respectively connected to the mounting base 1 and the bearing seat 2. In this embodiment, in order to ensure the stability of the support for the bearing seat 2, four return springs 3 are provided. The bearing seat 2 can slide up and down and can be reset under the action of the return springs 3.

[0031] Reference Figure 2 and Figure 4 The forging flash removal equipment also includes a limiting device 12 and a cutter 13 mounted on the mounting base 1. The limiting device 12 is used to limit the variable transmission ratio rack, and the cutter 13 is used to remove the flash. A pressing device 4 is also provided above the mounting base 1. The pressing device 4 is used to press the variable transmission ratio rack towards the cutter 13, i.e., downward, to remove the flash on the variable transmission ratio rack.

[0032] After the variable gear ratio rack is placed on the support seat 2, the limiting device 12 is used to limit the variable gear ratio rack. Then, the pressing device 4 can be used to press the variable gear ratio rack to move downward and at the same time drive the support seat 2 to move downward. The cutter 13 will cut off the flash on the variable gear ratio rack.

[0033] Reference Figure 2 and Figure 3 In this application, the return spring 3 is a nitrogen spring. The specific structure of the nitrogen spring is prior art and will not be described in detail here. The nitrogen spring ensures reliable support and constant support force for the variable transmission ratio rack regardless of where the support seat 2 is pressed and moved by the pressing device 4. Since the variable transmission ratio rack is located between the pressing device 4 and the support seat 2 when the pressing device 4 presses it, the variable transmission ratio rack will bear the force from the pressing device 4 and the support seat 2. After being subjected to force, the variable transmission ratio rack may experience internal stress concentration or even structural deformation. The nitrogen spring provided in this application can ensure that the variable transmission ratio rack is subjected to balanced force regardless of its position, thereby ensuring that the structure of the variable transmission ratio rack is not easily damaged.

[0034] Reference Figure 3 and Figure 5Since the nitrogen spring generates heat during operation, a cooling chamber 16 is formed between the slide groove 11 and the return spring 3 to prevent heat accumulation and performance problems. The mounting base 1 has an air inlet 14 and an air outlet 15 that communicate with the cooling chamber 16. Cold air is blown into the air inlet 14 by an external air blowing device, and the cold air enters the cooling chamber 16 to carry away the heat generated by the nitrogen spring during operation. The heat is then discharged from the air outlet 15, thus achieving heat dissipation.

[0035] Reference Figure 4 and Figure 5 The limiting device 12 is provided in two parts. The limiting device 12 includes a limiting block 121 that is detachably connected to the mounting base 1 by screws. There are two limiting blocks 121, which are located on both sides of the forging. The variable transmission ratio rack can be placed between the two limiting blocks 121.

[0036] Reference Figure 5 and Figure 6 In this embodiment, in order to facilitate the one-time removal of the flash on both sides of the variable transmission ratio rack, two cutters 13 are provided. Taking one of the cutters 13 structures as an example: the cutter 13 includes a mounting strip 131 connected to the mounting base 1. The upper end of the mounting strip 131 has a blade 132, which extends along the length direction of the mounting strip 131.

[0037] Reference Figure 5 and Figure 6 Specifically, the blade 132 has a first end 1321 and a second end 1322 opposite to each other in the length direction of the mounting strip 131. The first end 1321 is to the left of the second end 1322. The upper end face of the blade 132 is formed as a cutting surface 1323. The cutting surface 1323 gradually slopes downward from the first end 1321 to the second end 1322.

[0038] After the variable transmission ratio rack is placed on the support seat 2 along the length of the mounting strip 131, the variable transmission ratio rack is moved downward by the pressing device 4. The inclined cutting surface 1323 allows the blade 132 to gradually remove the flash. The cutting action of the blade 132 on the flash is similar to the cutting action of scissors. This design ensures that when the blade 132 cuts the flash, the contact area between the blade 132 and the flash is always controlled within a small range. This facilitates the cutting of the flash by the blade 132 and prevents the blade 132 from directly cutting off too large flash and cracking.

[0039] Reference Figure 3 and Figure 4The mounting base 1 is provided with a sliding column 5, which is arranged horizontally. A pressing head 51 is slidably connected to the sliding column 5. A pressing spring 52 is also sleeved on the sliding column 5. The two ends of the pressing spring 52 are respectively connected to the mounting base 1 and the pressing head 51. The pressing head 51 is located on the left side of the variable transmission ratio rack. The pressing head 51 can apply a force to the variable transmission ratio rack to move to the right under the action of the pressing spring 52.

[0040] Reference Figure 5 and Figure 6 and combined Figure 7 During the process of the variable gear ratio rack having its flash removed by the blade 132, applying a leftward force to the rack causes it to move to the left in the direction of the compression spring 52. This compresses the spring 52, and in conjunction with the downward movement of the rack, the cutting direction of the blade 132 on the flash is no longer vertical but oblique. In this embodiment, the cutting direction of the blade 132 is upward to the right. It should be noted that applying a leftward force to the variable gear ratio rack can be achieved by using a power output component such as a cylinder, or by manual pressing by a worker. After the force is applied, the compression spring 52 will extend, causing the compression head 51 to move to the right, thereby resetting the variable transmission ratio rack. This design, combined with the design of the inclined cutting surface 1323, makes it easier to remove burrs.

[0041] Reference Figure 6 To facilitate the collection and cleaning of burrs, a waste receiving part 133 is formed on the mounting strip 131 on one side of the blade 132. Burrs cut off by the blade 132 will collect on the waste receiving part 133 for cleaning.

[0042] Reference Figure 8 The pressing device 4 is located on the movable seat 41 above the mounting base 1. The movable seat 41 can be driven by a hydraulic cylinder or other actuators. The movable seat 41 is detachably connected to the pressing mold 42 by screws. The pressing mold 42 includes a mating arc groove 421 at the lower end. The mating arc groove 421 can fit against the outer wall of the shaft a. The movable seat 41 is also provided with an air nozzle 6 facing the pressing mold 42. The air nozzle 6 can spray compressed gas to blow away dirt or burrs that may stick on the pressing mold 42.

[0043] The implementation principle of the forging flash removal device in this embodiment is as follows: After the variable transmission ratio rack is placed on the support seat 2 and positioned between the two limits, the pressing mold 42 presses the variable transmission ratio rack by driving the moving seat 41 to move downward. The variable transmission ratio rack and the support seat 2 will move downward, and at this time the cutter 13 will cut off the burrs on the variable transmission ratio rack. The burrs will fall into the waste material support part 133.

[0044] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
