Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a split type unloading ring. Background Art

[0002] Automotive transmission parts such as drive shafts are the main components of automobiles. When machining drive shafts, a forging method is adopted. By pushing the cut steel into a mold, and then forming it into a corresponding shape through the mold. When the upper mold acts on the lower mold, during the action of the mold, unloading and cooling are required to assist in forming.

[0003] Among them, the commonly used existing unloading rings are as shown in the attached drawings. Its top is an installation surface, and the lower part is a stepped cylindrical structure. Cooling holes for cooling are provided in the upper part of the stepped cylindrical structure, and a notch is provided in the lower part of the stepped cylindrical structure. The notch divides the lower part of the stepped cylindrical structure into single strip-shaped plates. After forging, the strip-shaped plates expand outwards by being jacked up by a punch, thus completing the unloading of the workpiece. For the existing unloading rings, they are integrally manufactured, and the processing is relatively troublesome. At the same time, because the strip-shaped plates of the stepped cylindrical structure are rigidly connected to the outer wall of the unloading ring, when unloading, the entire strip-shaped plate is rigidly pushed by the workpiece. In this way, the position of the strip-shaped plate on the unloading ring is easily broken. And the cooling water is perpendicular to the workpiece, and the cooled medium is easily concentrated at the position where the strip-shaped plate is arranged on the unloading ring. In this way, when unloading, the strip-shaped plate is rigidly pushed by the workpiece, and due to the concentration of the cooling medium, the strip-shaped plate is prone to breakage and needs to be replaced as a whole, resulting in waste of the entire unloading ring. For this reason, we propose a split type unloading ring. Summary of the Invention

[0004] The purpose of the present invention is to provide a split type unloading ring to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A split type unloading ring, including a mounting plate. The bottom of the mounting plate is a cooling cylinder. A round hole communicating with the cooling cylinder is provided on the mounting plate. An installation groove is provided at the bottom of the cooling cylinder, and a clamping block is provided on the side wall of the installation groove. An installation body is installed in the installation groove, and a clamping edge is provided outside the installation body, and the clamping edge is connected to the clamping block; Multiple layers of cooling holes are provided on the cylinder wall of the cooling cylinder. The cooling holes at the top layer are inclined downward, and the cooling holes at the bottom layer are inclined upward; Multiple strip-shaped plates are connected to the bottom of the installation body at equal angles, and multiple layers of deformation grooves are provided on the strip-shaped plates.

[0006] Preferably, the areas of the multiple layers of deformation grooves decrease arithmetically from top to bottom.

[0007] Preferably, a wedge-shaped toroidal surface is provided on the outer ring of the mounting body, a cover plate is provided at the bottom of the mounting body, an insertion gap is formed between the wedge-shaped toroidal surface and the mounting groove, and a wedge-shaped insertion body inserted at the insertion gap is provided at the bottom of the cover plate. A profiling surface of the bottom of the mounting body is provided on the cover plate. Anti-slip holes are provided in the engaging block, and an anti-slip body is connected to the mounting body and inserted into the anti-slip holes.

[0008] Preferably, the anti-slip body is a bent rod, and the anti-slip hole is a bent groove.

[0009] Preferably, a spherical groove is provided on the engaging block, and a spherical stud is mounted on the mounting body and pressed into the spherical groove.

[0010] Preferably, the anti-slip body is a telescopic rod body, and the anti-slip hole is a cylindrical hole.

[0011] Preferably, the wedge-shaped insertion body and the insertion gap are in interference fit, and the height of the mounting body is lower than the height of the mounting groove.

[0012] Preferably, the cover plate is connected with a disassembly and assembly plate, and a disassembly and assembly groove is provided on the disassembly and assembly plate, and the disassembly and assembly plate covers the spherical stud.

[0013] Preferably, the strip-shaped plate is bent and deformed along the deformation groove after being pressed.

[0014] Preferably, a mounting surface for mounting is provided at the top of the mounting plate, a border plate is provided on the mounting plate, and mounting holes are provided in the border plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By providing a detachable cooling cylinder body and a mounting body, the present invention is easier to manufacture than the existing discharge ring. During use, since the cooling cylinder body is a cylindrical structure, it is integral and uniformly stressed. Thus, the cooling cylinder body is not easily damaged. For the strip-shaped plate on the mounting body, by designing multiple deformation grooves with different sizes, the strip-shaped plate can be bent and deformed at different positions, reducing the overall bending deformation of the strip-shaped plate during discharge demolding, thereby reducing the cracking of the strip-shaped plate. At the same time, by providing symmetric cooling holes arranged obliquely, it is easy to disperse the cooling liquid, avoiding the formation of convergence at the strip-shaped plate and reducing the damage to the strip-shaped plate.

[0016] The detachable cooling cylinder body and mounting body of the present invention can separately disassemble the damaged mounting body and strip-shaped plate, so as to maintain the continuous use of the cooling cylinder body, reduce waste, and the manufacturing of the separately disassembled mounting body and strip-shaped plate is easier to mold than the existing discharge ring.

[0017] In the present invention, by providing a cover plate, an interference fit is achieved through the wedge-shaped insertion body at the bottom of the cover plate and the insertion gap, so that the installation body can be stably installed at the installation groove position. At the same time, through the function of the disassembly and assembly plate, the cover plate and the insertion body can be withdrawn from the insertion gap, facilitating the disassembly and assembly of the installation body and the strip plate.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 - 11 The present invention provides a technical solution: a split unloading ring, which is used to solve the problem that the unloading ring of the existing automobile transmission parts such as the transmission shaft is easily damaged during forging, comprises a mounting plate 1, the top of the mounting plate 1 is provided with a mounting surface 11, the mounting surface 11 is lower than the top surface of the mounting plate 1, and is used to make an avoidance space with the installation position of the upper mold, the mounting plate 1 is provided with an extension plate 12, and the extension plate 12 is provided with a mounting hole 13. During installation, the mounting surface 11 is aligned with the installation position of the upper mold, and then the mounting plate 1 is fixedly installed at the installation position of the upper mold by passing the fixing parts such as bolts through the mounting hole 13.

[0032] The bottom of the mounting plate 1 is designed as a cooling cylinder 2. The cooling cylinder 2 is cylindrical in shape and has a through hole inside. The through hole inside is used to pass the punch and the workpiece. A circular hole connected to the cooling cylinder 2 is opened on the mounting plate 1. A mounting groove 21 is opened at the bottom of the cooling cylinder 2. The design of the mounting groove 21 is as shown in the attached figure. Figure 5 As shown, its outer shape is composed of an arc segment and a straight line, and a snap-fit ​​block 22 is provided on the straight side wall of the mounting groove 21. After the snap-fit ​​block 22 is filled, the through hole at the bottom of the cooling cylinder 2 is in a shape formed by splicing an arc and a straight line. A mounting body 3 is installed in the mounting groove 21, and a snap-fit ​​edge 4 is provided on the outside of the mounting, and the snap-fit ​​edge 4 is connected to the snap-fit ​​block 22. The mounting body 3 and the mounting groove 21 are designed with an arc segment. In order to facilitate the assembly of the two, a straight line edge is designed to prevent the mounting body 3 from relative rotation in the mounting groove 21. When the mounting body 3 is assembled in the mounting groove 21, a complete circular hole is formed at the bottom of the cooling cylinder 2. The diameter of the circular hole is smaller than the diameter of the upper part of the cooling cylinder 2, and the diameter of the circular hole is much larger than the punch, thereby facilitating the passage of the punch.

[0033] A plurality of cooling holes 5 are provided on the wall of the cooling cylinder 2. The cooling holes 5 on the top layer are distributed obliquely downward, and the cooling holes 5 on the bottom layer are distributed obliquely upward. The cooling liquid enters the cooling cylinder 2 through the cooling holes 5 to cool the workpiece. The specific flow direction of the cooling liquid through the cooling holes 5 is shown in the attached figure. Figure 11As shown, the cooling liquid is obliquely injected into the interior of the cooling cylinder from the upper cooling holes 5 and the lower cooling holes 5. For the cooling water in the middle layer, it vertically enters the interior of the cooling cylinder 2. In this way, the cooling liquid in the upper part quickly contacts the workpiece and the mold, achieving rapid cooling. At the same time, the middle layer is intensively cooled. The cooling liquid at the bottom is also obliquely injected into the interior of the cooling cylinder 2. On the one hand, it is convenient to further strengthen the cooling process. At the same time, the cooling liquid obliquely ejected upward at the bottom is convenient to impact the cooling liquid in the upper part, avoiding the convergence of the cooling liquid, thereby reducing the damage to the strip plate 6.

[0034] A plurality of strip plates 6 are equally-angularly connected to the bottom of the installation body 3. The strip plates 6 are made of plate-shaped steel and are fixed to the installation body 3 by welding or other means. Compared with the existing strip plates cut out by cutting at the bottom of the unloading ring, the design of the strip plates 6 in this scheme effectively avoids the pulling between adjacent strip plates 6, thereby reducing the cracking of the strip plates 6. After being pressed, the strip plates 6 bend and deform along the deformation grooves, and multiple layers of deformation grooves 7 are provided on the strip plates 6. The area of the multiple layers of deformation grooves 7 decreases arithmetically from top to bottom. The design of the strip plates 6 and the deformation grooves 7 is as shown in the appendix Figure 7 As shown in the appendix, when the punch moves upward, after pushing the workpiece, the workpiece contacts the strip plate 6, so that the strip plate 6 bends and deform along the deformation grooves 7. The bending deformation trajectory of the strip plate 6 is as shown in the appendix Figure 10 As shown in the appendix, for those that need slight deformation, the strip plate 6 bends along the topmost deformation groove 7, that is, it bends and deforms from the largest area. In this way, according to the unloading of transmission parts of different lengths, it can be bent and unloaded according to different bending degrees, thereby avoiding the bending deformation of the entire strip plate 6 from the connection position with the unloading ring, reducing the tearing of the strip plate 6 during bending unloading. At the same time, the layer-by-layer deformation not only applies to the unloading of transmission shafts of different sizes, but also helps to release the bending deformation force of the strip plate 6 layer by layer during unloading, thereby reducing the damage to the strip plate 6.

[0035] In order to increase the installation stability between the installation body 3 and the installation groove 21, a wedge-shaped annular surface 31 is provided on the outer circle of the installation body 3. The arc section of the installation body 3 is machined into a tapered surface with a taper ranging from 10° to 45° by a lathe. Part of the tapered surface can be selected, or the entire arc section can be machined into the wedge-shaped annular surface 31. For the convenience of machining, in this solution, the entire arc section is machined into the wedge-shaped annular surface 31. A cover plate 8 is provided at the bottom of the installation body 3. An insertion gap 32 is formed between the wedge-shaped annular surface 31 and the installation groove 21, and a wedge-shaped insertion body 81 inserted at the insertion gap 32 is provided at the bottom of the cover plate 8. The overall height of the wedge-shaped insertion body 81 is higher than the height of the installation body 3. The wedge-shaped insertion body 81 and the insertion gap 32 are in interference fit, and the height of the installation body 3 is 1 - 3 mm lower than that of the installation groove 21. In this way, the bottom of the wedge-shaped insertion body 81 is aligned with the insertion gap 32 and inserted. After the wedge-shaped insertion body 81 is inserted, the cover plate 8 is struck by knocking the workpiece with a hammer or the like, so that the wedge-shaped insertion body 81 is completely inserted, and the wedge-shaped insertion body 81 and the insertion gap 32 complete the interference fit, making the installation body 3, the wedge-shaped insertion body 81, and the cooling cylinder body 2 form a complete body.

[0036] To facilitate the passage of the strip plate 6 on the installation body 3, a profiling surface at the bottom of the installation body 3 is provided on the cover plate 8. When the wedge-shaped insertion body 81 is inserted into the cooling cylinder body 2, the cover plate 8 just covers the installation body 3 and is flush with the bottom of the cooling cylinder body 2, thus facilitating the processing and forming of the steel by the mold.

[0037] To increase the stability of the installation body 3 in the installation groove 21 and prevent the relative rotation of the installation body 3 during the insertion of the wedge-shaped insertion body 81, an anti-slip hole groove 23 is provided on the engaging block 22, and an anti-slip body 9 is connected to the installation body 3, and the anti-slip body 9 is inserted into the anti-slip hole groove 23.

[0038] Embodiment 1: The anti-slip body 9 is designed as a bent rod, and the anti-slip hole groove 23 is a bent groove. In this way, when the installation body 3 is assembled in the installation groove 21, first align the bent rod with the bent groove, and hold the arc part of the installation body 3 by hand. When the bent rod is inserted into the bent groove, then turn the direction of the arc part of the installation body 3. Through the cooperation of the bent rod and the bent groove, the relative rotation of the installation body 3 is avoided.

[0039] To increase the engagement stability between the bent rod and the bent groove, a spherical groove 24 is provided on the engaging block 22, and a spherical column 33 is installed on the installation body 3. After the bent rod is inserted into the bent groove, by pressing the spherical column 33 into the spherical groove 24, the straight edge of the installation body 3 is restricted, thus preventing the installation body 3 from rotating.

[0040] Embodiment 2: The anti-slip body 9 is a telescopic rod body, and the anti-slip hole groove 23 is a cylindrical hole. When assembling the mounting body 3, first press and contract the telescopic rod body until the anti-slip body 9 is inserted into the anti-slip hole groove 23, thereby preventing the mounting body 3 from rotating.

[0041] To facilitate the replacement of the strip plate 6 after damage, a disassembly and assembly plate 82 is connected to the cover plate 8, and a disassembly and assembly groove 83 is provided on the disassembly and assembly plate 82. The disassembly and assembly plate 82 covers the spherical clamping post 33. In this way, by hanging the disassembly and assembly groove 83 with a hook or the like and pulling it outwards, the cover plate 8 and the wedge-shaped insertion body 81 are pulled out from the insertion gap 32, so that the mounting body 3 is removed from the mounting groove 21, thereby completing the replacement of the mounting body 3 and the strip plate 6. For a single damaged strip plate 6, it can be re-welded to complete.

[0042] During specific use, first align the mounting surface 11 with the mounting position of the upper die, and then pass fixing parts such as bolts through the mounting holes 13 to fixedly install the mounting plate 1 at the mounting position of the upper die; then the mounting body 3 needs to be assembled in the mounting groove 21. Hold the arc part of the mounting body 3 by hand, insert the anti-slip body 9 into the anti-slip hole groove 23, and then assemble the mounting body 3 in the mounting groove 21. During the forming process, the specific flow direction of the cooling liquid through the cooling holes 5 is as shown in the appendix Figure 11 As shown, the cooling liquid is obliquely injected into the cooling cylinder body from the upper cooling holes 5 and the lower cooling holes 5. For the cooling water in the middle layer, it vertically enters the cooling cylinder body 2. In this way, the cooling liquid in the upper part quickly contacts the workpiece and the die, realizing rapid cooling. At the same time, the middle layer is centrally cooled. The cooling liquid at the bottom is also obliquely injected into the cooling cylinder body 2. On the one hand, it is convenient to further strengthen the cooling process. At the same time, the cooling liquid obliquely ejected upwards at the bottom is convenient to impact the cooling liquid in the upper part, avoiding the convergence of the cooling liquid, thereby reducing the damage to the strip plate 6; after the forming is completed, the punch pushes upwards, so that the workpiece presses the strip plate 6 to deform, and the workpiece contacts the strip plate 6, so that the strip plate 6 is bent and deformed along the deformation groove 7. The bending deformation track of the strip plate 6 is as shown in the appendix Figure 10As shown in the figure, for those that require slight deformation, the strip plate 6 is bent along the topmost deformation groove 7, that is, bent and deformed from the largest area. In this way, according to the discharging of transmission parts of different lengths, bending and discharging can be carried out according to different bending degrees, thus avoiding the bending deformation of the entire strip plate 6 from the connection position with the discharging ring, reducing the tearing situation that occurs when the strip plate 6 is bent and discharged. At the same time, the layer-by-layer deformation not only applies to the discharging of transmission shafts of different sizes, but also helps to gradually release the bending deformation force of the strip plate 6 during discharging, thereby reducing the damage to the strip plate 6. In order to facilitate the replacement of the strip plate 6 after damage, a disassembly and assembly plate 82 is connected to the cover plate 8, and a disassembly and assembly groove 83 is provided on the disassembly and assembly plate 82. The disassembly and assembly plate 82 covers the spherical clamping post 33. In this way, by hanging on the disassembly and assembly groove 83 with a hook or the like and pulling it outwards, the cover plate 8 and the wedge-shaped insertion body 81 are pulled out from the insertion gap 32, so as to remove the installation body 3 from the installation groove 21, thereby completing the replacement of the installation body 3 and the strip plate 6. For the damage of a single strip plate 6, it can be re-welded to complete the replacement.
