Description

Technical Field

[0001] This utility model relates to the field of brake oil pipe joint processing, and in particular to a composite mold for pressing a sealing ring and punching a notch on a non-standard brake oil pipe joint. Background Technology

[0002] The traditional manufacturing process for irregular-shaped brake hose connectors involves: cold forging the notch at the front end of the connector; drilling a large hole using the bottom surface of the notch as a guide; however, due to the arc-shaped inner wall of the notch, instability frequently occurs during positioning, leading to inconsistent dimensions between the center of the large hole and the notch, thus affecting vehicle installation; furthermore, the beveled surface of the head of the irregular-shaped brake hose connector typically requires milling, during which burrs can become embedded in the notch edge, necessitating manual deburring; finally, a sealing ring is pressed in using the large hole as a guide. This manufacturing process is not only costly but also results in inconsistent product quality, thus requiring improvement. Utility Model Content

[0003] Therefore, it is necessary to address the problems of high manufacturing costs and unstable processing quality associated with traditional non-standard brake hose connector processing technology by providing a composite mold for pressing a sealing ring and punching notches for non-standard brake hose connectors.

[0004] This utility model provides a composite mold for a non-standard brake hose connector pressure sealing ring and a punched notch, comprising:

[0005] Upper mold base;

[0006] The sleeve is fixedly connected to the bottom of the upper mold base;

[0007] A notched punch is fixedly connected to the bottom of the upper die holder;

[0008] The lower mold base is located below the upper mold base and has a groove on its surface;

[0009] The lower mold core rod is fixedly connected in the slot and is coaxial with the sleeve, and its outer diameter is the same as the inner diameter of the sleeve.

[0010] When the irregular brake hose connector is snapped into the slot, the lower mold core is located in the round hole on the surface of the irregular brake hose connector, and a sealing ring is fitted on the outer wall of the lower mold core, which is located on the surface of the irregular brake hose connector.

[0011] In one embodiment, when the notched punch punches the notched burrs of the irregular brake oil pipe joint, the sleeve is fitted on the outer wall of the lower die mandrel, and the sleeve is slidably connected to the lower die mandrel.

[0012] In one embodiment, the distance between the lower end of the notched punch and the surface of the shaped brake hose connector is less than the distance between the lower end of the sleeve and the surface of the shaped brake hose connector.

[0013] In one embodiment, the slot includes a rectangular slot and an arc-shaped slot, with the lower mold core rod located within the rectangular slot.

[0014] In one embodiment, a guide plate is fixedly connected to the bottom of the upper die base, the guide plate is fixedly connected to the notched punch, and a guide groove is formed on the surface of the lower die base, with the guide plate slidably connected in the guide groove.

[0015] In one embodiment, a waste groove is provided on the surface of the lower mold base.

[0016] The aforementioned composite mold for pressing the sealing ring and punching the notch of the irregular brake hose connector has several advantages. First, it uses the circular hole of the irregular brake hose connector as the positioning point during both the pressing of the sealing ring and the punching of the notch and burrs, effectively ensuring the distance between the center of the circular hole and the inner wall of the notch. Second, during the cold forging process of the notch, the irregular geometry of the part can easily lead to some deviations in the shape of the notch after forming. However, during the punching of the notch and burrs in this mold, the notch punch will perform fine punching on the original cold forging notch, making the notch shape of the irregular brake hose connector more regular and the size more uniform, thus improving the stability of the processing quality of the irregular brake hose connector. At the same time, by completing the pressing of the sealing ring and the removal of the notch and burrs in one extrusion on the mold, the manufacturing cost is reduced. Attached Figure Description

[0028] The following combination Figure 1-Figure 3 This invention describes the pressure sealing ring and punched notch composite mold for the irregularly shaped brake oil pipe joint.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a composite mold for a non-standard brake hose connector pressure sealing ring and punch notch includes an upper mold base 100, a sleeve 200, a notch punch 300, a lower mold base 400, and a lower mold core rod 500.

[0030] The sleeve 200 is fixedly connected to the bottom of the upper mold base 100.

[0031] The notched punch 300 is fixedly connected to the bottom of the upper die holder 100.

[0032] The lower mold base 400 is located below the upper mold base 100, and the surface of the lower mold base 400 has a slot 410.

[0033] The lower mold core rod 500 is fixedly connected in the slot 410, and the lower mold core rod 500 is coaxial with the sleeve 200, and the outer diameter of the lower mold core rod 500 is the same as the inner diameter of the sleeve 200.

[0034] When the irregular brake hose connector is snapped into the slot 410, the lower mold core rod 500 is located in the round hole on the surface of the irregular brake hose connector, and the outer wall of the lower mold core rod 500 is fitted with a sealing ring 600, which is located on the surface of the irregular brake hose connector.

[0035] The specific working principle is as follows: By placing the irregular brake hose connector and the sealing ring 600 into the lower die core 500, as the upper die base 100 presses down, the lower die core 500 is first guided into the inner hole of the sleeve 200. At this time, the entire irregular brake hose connector is fixed. The upper die base 100 continues to press down, and the notch punch 300 begins to contact the upper surface of the notch of the irregular brake hose connector, preparing to punch the notch burrs. After the notch burrs are punched, the upper die base 100 presses down further, and when it reaches the bottom dead center, the sleeve 200 completes the pressing of the sealing ring 600. After the sealing ring 600 is pressed, the upper and lower dies separate, and the irregular brake hose connector that has been processed by pressing the sealing ring and removing the notch burrs is taken out.

[0036] This composite mold for pressing the sealing ring and punching the notch of the irregular brake hose connector has several advantages. First, during the pressing of the sealing ring 600 and the punching of the notch and burrs, the circular hole of the irregular brake hose connector is used as the positioning, which can effectively ensure the distance between the center of the circular hole and the inner wall of the notch. Second, during the cold forging process of the notch, the irregular geometry of the part can easily lead to some deviation in the shape of the notch after forming. However, during the punching of the notch and burrs in this mold, the notch punch 300 will perform fine punching on the original cold forging notch, so that the notch shape of the irregular brake hose connector is more regular and the size is more uniform, which improves the stability of the processing quality of the irregular brake hose connector. At the same time, by pressing the sealing ring and removing the notch and burrs on the mold in one extrusion, the manufacturing cost is reduced.

[0037] In this embodiment, when the notched punch 300 punches the notch burr of the irregular brake oil pipe joint, the sleeve 200 is sleeved on the outer wall of the lower die mandrel 500, and the sleeve 200 is slidably connected to the lower die mandrel 500.

[0038] To facilitate the punching of notches and burrs, the lower die mandrel 500 can be first inserted into the inner hole of the sleeve 200, thereby fixing the entire irregular brake oil pipe joint and preventing displacement of the irregular brake oil pipe joint during the punching of notches and burrs, which would affect the processing quality.

[0039] In this embodiment, the distance between the lower end of the notched punch 300 and the surface of the irregular brake hose connector is less than the distance between the lower end of the sleeve 200 and the surface of the irregular brake hose connector.

[0040] Using the round hole of the irregular brake hose connector as a positioning tool, the notch of the irregular brake hose connector is finely punched, and then the sealing ring 600 is pressed onto the irregular brake hose connector. This effectively ensures the distance between the center of the round hole and the inner wall of the notch, and at the same time, it effectively solves the problems of irregular notch shape and uneven size.

[0041] In this embodiment, the slot 410 includes a rectangular slot 411 and an arc-shaped slot 412, and the lower mold core rod 500 is located in the rectangular slot 411.

[0042] Since the irregular brake hose connector consists of a hose and a rectangular head, the rectangular groove 411 and the arc groove 412 can effectively prevent the irregular brake hose connector from shifting during the processing, thus improving the processing quality.

[0043] In this embodiment, a guide plate 110 is fixedly connected to the bottom of the upper mold base 100, and the guide plate 110 is fixedly connected to the notched punch 300. A guide groove 430 is opened on the surface of the lower mold base 400, and the guide plate 110 is slidably connected in the guide groove 430.

[0044] By placing the guide plate 110 into the corresponding guide groove 430, the positions of the upper mold base 100 and the lower mold base 400 can be quickly and easily positioned, thereby making the sleeve 200 and the lower mold core 500 coaxial.

[0045] In this embodiment, a waste groove 420 is provided on the surface of the lower die holder 400, so as to facilitate the discharge of waste generated during the punching and burring process from the waste groove 420.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
