Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a simple pressing mold for a drive shaft mounting beam locking bolt assembly. Background Technology

[0002] In existing technologies, the stamping process for the drive shaft mounting beam locking bolt assembly suffers from a core problem: incomplete forming in a single operation. Partial shaping of the component requires manual refining. This processing method has the following key drawbacks: Poor dimensional accuracy and appearance quality: The lack of a unified forming standard results in inconsistent flange angles and heights for manually refinished parts, and they are prone to scratches and deformation due to tool contact, making it impossible to guarantee the quality consistency with mass-produced parts. Insufficient positioning stability: During manual operation, parts are prone to drifting back and forth, which further leads to out-of-tolerance critical dimensions and a high scrap rate; Low production efficiency and high cost: Manually sorting individual parts is time-consuming and the efficiency is far from meeting the project cycle; at the same time, a large amount of labor costs are required, and human error will increase the cost of scrapping parts, and there are also processing safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a simple pressing mold for the drive shaft mounting beam locking bolt assembly, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a simplified pressing mold for a drive shaft mounting beam locking bolt assembly, comprising a bottom mold unit and a pressing unit. The bottom mold unit includes a bottom plate and recessed positioning blocks installed on both sides of the bottom plate. The pressing unit includes a pressing plate and guide posts installed at the bottom of the pressing plate. The drive shaft mounting beam locking bolt assembly is placed on the lower surface of the pressing plate, and the guide posts are inserted into the through holes on the drive shaft mounting beam locking bolt assembly. Then, the drive shaft mounting beam locking bolt assembly and the pressing plate are placed above the recessed positioning blocks. At this time, an external hydraulic mechanism is used to push the pressing plate downward, causing the middle position of the drive shaft mounting beam locking bolt assembly to deform downward, while the part in contact with the recessed positioning block is turned upward.

[0005] Preferably, multiple bearing blocks are installed above the base plate, and the bearing blocks are contacted after the beam locking bolt of the transmission shaft deforms downward at the middle position.

[0006] Preferably, a support frame is fixedly connected to the bottom of the base plate.

[0007] Preferably, guide plates are fixedly connected to both sides of the pressing plate.

[0008] Preferably, the two guide plates can contact the sides of the base plate after the pressing plate moves downward, and the front of the guide plates can contact the cavity positioning block.

[0009] Preferably, the width of the pressing plate is smaller than the width of the base plate.

[0010] The technical effects and advantages of this utility model are as follows: the cavity positioning block of the bottom mold unit provides a unified benchmark for the flanging of the parts, ensuring that the flanging shape of all parts is consistent; the guide post of the pressing unit is inserted into the through hole of the workpiece, which can prevent the parts from drifting back and forth during pressing and avoid dimensional deviation; the bearing block above the bottom plate can provide stable support when the workpiece deforms downward in the middle position, avoiding excessive or uneven deformation and further ensuring the core dimensional accuracy; at the same time, mechanized pressing replaces manual hammering, and there are no tool scratches on the surface of the parts, significantly improving the appearance quality.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This utility model provides, for example Figures 1-3The simplified pressing mold for the drive shaft mounting beam locking assembly shown includes a bottom mold unit 1 and a pressing unit 2. The bottom mold unit 1 includes a bottom plate 11 and recessed positioning blocks 13 installed on both sides of the bottom plate 11. The pressing unit 2 includes a pressing plate 21 and guide posts 22 installed at the bottom of the pressing plate 21. The drive shaft mounting beam locking assembly is placed on the lower surface of the pressing plate 21, and the guide posts 22 are inserted into the through holes on the drive shaft mounting beam locking assembly. Then, the drive shaft mounting beam locking assembly and the pressing plate 21 are placed above the recessed positioning blocks 13. At this time, the pressing plate 21 is pushed downward by an external hydraulic mechanism, so that the middle position of the drive shaft mounting beam locking assembly is deformed downward, while the part in contact with the recessed positioning blocks 13 is turned upward.

[0015] Furthermore, multiple bearing blocks 12 are installed above the base plate 11, and after deforming downwards at the middle position of the drive shaft mounting beam locking bolt assembly, they come into contact with the bearing blocks 12.

[0016] Furthermore, a support frame 14 is fixedly connected to the bottom of the base plate 11.

[0017] Furthermore, guide plates 23 are fixedly connected to both sides of the pressing plate 21.

[0018] Furthermore, after the pressing plate 21 moves downward, the two guide plates 23 can contact the sides of the base plate 11, and at the same time, the front of the guide plates 23 can contact the cavity positioning block 13.

[0019] Furthermore, the width of the pressing plate 21 is smaller than the width of the base plate 11.

[0020] Take the drive shaft mounting beam locking bolt assembly to be processed, attach it to the lower surface of the pressing plate 21 of the pressing unit 2, adjust the position of the workpiece, and make the guide post 22 accurately inserted into the preset through hole of the workpiece to complete the positioning of the workpiece and the pressing plate 21. Hold the pressing plate 21 and place the positioned workpiece and the pressing plate 21 together on the cavity positioning block 13 of the bottom mold unit 1, ensuring that the edge of the workpiece is aligned with the forming surface of the cavity positioning block 13.

[0021] The external hydraulic mechanism is activated, and the hydraulic rod pushes the pressing plate 21 to move vertically downward: During the downward movement, the guide plates 23 on both sides of the pressing plate 21 first contact the sides of the bottom plate 11, and at the same time, the front of the guide plate 23 fits the cavity positioning block 13, so that the auxiliary pressing unit 2 can move vertically and avoid deviation. As the pressing plate 21 continues to move downward, the middle position of the workpiece first contacts the bearing block 12 on the base plate 11 and deforms downward. At the same time, the two sides of the workpiece contact the cavity positioning block 13 and are constrained to turn upward until the workpiece completely fits the forming surface of the cavity positioning block 13 and the bearing block 12, thus completing the entire shaping process.

[0022] When the hydraulic mechanism is closed, the hydraulic rod drives the pressing plate 21 to reset vertically upward. After the pressing plate 21 is reset to a safe height, hold the pressing plate 21 and lift it upward, causing the formed workpiece to detach from the cavity positioning block 13 and the bearing block 12 of the bottom mold unit 1. Finally, remove the workpiece from the guide post 22 to complete a single processing flow and proceed to the cycle operation of the next workpiece.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
