Description

Technical Field

[0001] This utility model relates to the field of stabilizer bar forming technology, and in particular to a forging die for forming the end of a stabilizer bar. Background Technology

[0002] In the process of forming stabilizer bar ends, conventional techniques typically employ a one-step forging combined with a one-step punching process to ensure the end shape meets drawing requirements. However, existing techniques have significant drawbacks: First, due to uneven wall thickness at the stabilizer bar end, burrs are easily generated during punching, especially in areas with thicker walls. Second, these burrs cannot be automatically removed in subsequent processes and require manual visual inspection and polishing. However, manual polishing is unpredictable, easily leading to enlarged hole diameters and dimensional deviations, thus affecting product assembly accuracy. Furthermore, residual burrs reduce the product's appearance quality, increase the risk of scratches or abrasions, and ultimately impact customer satisfaction.

[0003] In existing technologies, although forging and punching processes can complete basic forming, their ability to control burrs is insufficient, resulting in additional labor costs and quality risks. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a forging die for forming the end of a stabilizer bar, which can remove burrs generated during product punching and reduce factors affecting the product's appearance.

[0005] To solve the above-mentioned technical problems, the present invention provides a forging die for forming the end of a stabilizer bar, comprising: a lower die and an upper die. The lower die includes a lower template and a lower forging block, a lower cutting edge punching block, and a lower shaping block disposed on the lower template. The upper die includes an upper template and an upper forging block, a punch, an upper shaping block, and an upper first fixing block disposed on the upper template. An upper cutting edge punching block is slidably fitted on the upper first fixing block, and the punch is fixedly connected to the upper first fixing block. The upper forging block is disposed above the lower forging block. When the die is closed, the end of the stabilizer bar is located between the upper and lower forging blocks, and the end of the stabilizer bar is forged to a certain thickness under the action of the upper and lower forging blocks. The upper cutting edge punching block is disposed above the lower cutting edge punching block, and a first cutting edge punching block is formed on the upper cutting edge punching block to cooperate with the punch. A through hole is provided, and a second through hole is provided on the lower cutting edge punch block to cooperate with the punch. When the mold is closed, the end of the stabilizer bar is between the upper and lower cutting edge punch blocks. The upper cutting edge punch block falls down and, with the cooperation of the lower cutting edge punch block, cuts off the excess part of the end of the stabilizer bar, which is forged to a certain thickness. When the upper cutting edge punch block moves up, the punch passes through the second through hole to punch the end of the stabilizer bar. The upper shaping block is set above the lower shaping block. A protrusion extends upward on the lower shaping block. The protrusion is matched with the depth and diameter of the punch at the end of the stabilizer bar. When the mold is closed, the end of the stabilizer bar is between the upper and lower shaping blocks and the punch at the end is coaxial with the protrusion. The upper shaping block falls down and punches the punch at the end of the stabilizer bar onto the protrusion, thereby removing the burrs at the punch and shaping the end of the stabilizer bar.

[0006] Preferably, the lower template and the upper template are slidably fitted with the upper mounting plate and the lower mounting plate of the forging press, respectively, and a connecting guide post is slidably provided between the lower template and the upper template to enable synchronous sliding displacement between the lower template and the upper template.

[0007] Preferably, a driving component is connected to the lower mounting plate, and one end of the driving component is connected to the lower template.

[0008] Preferably, one end of the lower cutting edge punching block is provided with a cutting edge positioning block. The cutting edge positioning block is used to position the end of the stabilizing rod on the lower cutting edge punching block to ensure the consistency of the cutting and punching positions.

[0009] Preferably, a material unloading block is provided on the lower template, and a lower cutting edge punching block is provided on the material unloading block. A waste discharge hole is provided on the material unloading block, which is used to receive the waste generated when the end of the stabilizer rod is punched.

[0010] The beneficial effects of this utility model are: by setting a protrusion on the lower shaping block that matches the punching hole at the end of the stabilizing rod, the burrs generated during punching are removed and the final shaping is performed, reducing factors that affect the appearance of the product, solving the problem of workers removing burrs, and reducing the probability of scratches or abrasions on the end caused by external factors.

[0029] Example:

[0030] refer to Figures 1-4 A forging die for forming the end of a stabilizer bar includes a lower die and an upper die. The lower die includes a lower template 1 and a lower forging block 11, a lower cutting and punching block 12, and a lower shaping block 13 disposed on the lower template 1.

[0031] The upper die includes an upper template 2 and an upper forging block 21, a punch 22, an upper shaping block 23, and an upper first fixing block 24 disposed on the upper template 2. An upper cutting edge punching block 25 is slidably fitted on the upper first fixing block 24, and the upper first fixing block 24 is fixedly connected to the punch 22.

[0032] The upper forging block 21 is arranged above the lower forging block 11. When the mold is closed, the end of the stabilizer is between the upper forging block 21 and the lower forging block 11. Under the action of the upper forging block 21 and the lower forging block 11, the end of the stabilizer is forged to a certain thickness.

[0033] The upper cutting edge punching block 25 is arranged above the lower cutting edge punching block 12. The upper cutting edge punching block 25 has a first through hole 251 that cooperates with the punch 22. The lower cutting edge punching block 12 has a second through hole 121 that cooperates with the punch 22. When the mold is closed, the end of the stabilizer bar that has been forged to a certain thickness is located between the upper cutting edge punching block 25 and the lower cutting edge punching block 12. The upper cutting edge punching block 25 falls down and, with the cooperation of the lower cutting edge punching block 12, cuts off the excess part of the end of the stabilizer bar that has been forged to a certain thickness. When the upper cutting edge punching block 25 is blocked from cutting the edge, the upper cutting edge punching block 25 is forced to slide upward on the upper first fixing block 24. The punch 22 passes through the second through hole 121 to punch the end of the stabilizer bar.

[0034] The upper shaping block 23 is arranged above the lower shaping block 13. The lower shaping block 13 has an upward protrusion 131. The depth and diameter of the protrusion 131 match the punching hole at the end of the stabilizer rod. When the mold is closed, the end of the stabilizer rod is between the upper shaping block 23 and the lower shaping block 13, and the punching hole at the end is coaxial with the protrusion 131. When the upper shaping block 23 falls, it punches the punching hole at the end of the stabilizer rod onto the protrusion 131, thereby removing the burrs at the punching hole at the end of the stabilizer rod and shaping the end of the stabilizer rod.

[0035] refer to Figures 1-4 The lower template 1 and the upper template 2 are slidably fitted with the upper mounting plate 4 and the lower mounting plate 5 of the forging press, respectively. A connecting guide post is slidably provided between the lower template 1 and the upper template 2 so that the lower template 1 and the upper template 2 slide synchronously. A driving component 3 is connected to the lower mounting plate 5. The driving component 3 can be a cylinder. One end of the driving component 3 is connected to the lower template 1, so the driving component 3 can control the position of the lower template 1. The lower template 1 drives the upper template 2 to move synchronously. With the horizontal position of the end of the stabilizer bar remaining unchanged, the driving component 3 drives the positions of the lower template 1 and the upper template 2, thereby switching the positions of the upper forging block 21 and the lower forging block 11, the upper cutting edge punching block 25 and the lower cutting edge punching block 12, the upper forming block 23 and the lower forming block 13, and thus completing the processing of the end of the stabilizer bar.

[0036] refer to Figure 2 One end of the lower cutting edge punch block 12 is bolted to a cutting edge positioning block 122. The height of one end of the cutting edge positioning block 122 is higher than the upper end face of the lower cutting edge punch block 12. Thus, when the end of the stabilizer bar is between the upper cutting edge punch block 25 and the lower cutting edge punch block 12 and is placed on the lower cutting edge punch block 12, the cutting edge positioning block 122 blocks one side of the stabilizer bar end, thereby positioning the stabilizer bar end on the lower cutting edge punch block 12, thus ensuring the consistency of the cutting and punching position at the end of the stabilizer bar.

[0037] refer to Figure 2 and Figure 3 The lower template 1 is bolted to the unloading block 14, and the lower cutting edge punching block 12 is bolted to the unloading block 14. The unloading block 14 is provided with a waste discharge hole 141. The waste discharge hole 141 is used to receive the waste generated when the end of the stabilizer bar is punched. Thus, the upper cutting edge punching block 25 falls down and, with the cooperation of the lower cutting edge punching block 12, cuts off the excess part of the end of the stabilizer bar that has been forged to a certain thickness, and the waste generated by the punch 22 punching the end of the stabilizer bar through the second through hole 121 is discharged through the waste discharge hole 141.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
