Description

Technical Field

[0001] This utility model relates to the field of push rod fork technology, and in particular to a push rod fork deburring assembly. Background Technology

[0002] Currently, vehicle braking systems typically include power boosters, which can be broadly categorized into vacuum boosters, hydraulic boosters, and pneumatic boosters.

[0003] When a vehicle brakes, the driver presses the brake pedal, which amplifies the force through a linkage mechanism and leverage principle, and transmits it to the push rod fork. The force is then input into the booster via the push rod, and after being amplified again by the booster, the vehicle brakes through friction.

[0004] The existing push rod fork manufacturing process, as described in CN112059538A, includes the following steps: blanking, where sheet metal is processed into a base plate by a punch press; blanking, where bar stock is processed into a base rod by a punch press; precision finishing, where the base rod is placed on a CNC machine tool, and the end face of the base rod used for welding is precision machined and flattened to produce a strip rod; welding, where the base plate and strip rod are placed on a welding machine, with the strip rod perpendicular to the base plate and the end of the strip rod used for welding abutting against the base plate, completing the welding of the strip rod and the base plate to form a blank; and forming, where the blank is placed on a punch press, the strip rod is fixed, and the base plate is bent to form a push rod fork. Between the blanking and welding steps, deburring is also included, where the base plate is placed in a laminar flow machine and subjected to laminar flow treatment.

[0005] Deburring the push rod fork requires removing it from the progressive die before deburring, which is inefficient.

[0006] Therefore, it is necessary to improve the existing push rod fork deburring assembly. Utility Model Content

[0007] The purpose of this invention is to overcome the defects in the existing technology and provide a push rod fork deburring component, which is integrated in the progressive die. The deburring operation can be completed when the push rod fork is demolded from the progressive die.

[0008] To achieve the above technical effects, the technical solution of this utility model is as follows: a push rod fork deburring assembly, comprising a push rod fork forming progressive die, a chamfering assembly, and a limiting assembly. The push rod fork forming progressive die includes a support platform and a cutting assembly. The support platform is used to support the finished push rod fork and the push rod fork material strip during die closing. The cutting assembly is used to cut the finished push rod fork from the push rod fork material strip. The chamfering assembly is disposed on the discharge side of the cutting assembly. The chamfering assembly includes an arc-shaped chamfer fixedly disposed on the support platform. The arc-shaped chamfer abuts against the burr edges of two adjacent finished push rod forks. The arc-shaped chamfer is used to squeeze and remove the burr edges during die closing. The limiting assembly is disposed on the discharge side of the chamfering assembly. The limiting assembly cooperates with the cutting assembly to fix the position of the finished push rod fork during die closing.

[0009] According to one embodiment of the present invention, the push rod fork forming progressive die includes a fixedly disposed lower die and a lifting disposed upper die, and the support platform is fixedly connected to the lower die.

[0010] According to one embodiment of the present invention, the cutting assembly includes a punching blade, which is fixedly connected to the upper die. The punching blade is provided with a cutting edge for punching waste material and an abutting surface that abuts against the side wall of the finished push rod fork.

[0011] According to one embodiment of the present invention, the limiting component includes an abutment plate that abuts against the side wall of the finished push rod fork, a driving component that drives the abutment plate to abut against or separate from the finished push rod fork, and a mounting plate that is fixedly connected to the lower mold, wherein the driving component is connected to the mounting plate.

[0012] According to one embodiment of the present invention, the driving assembly includes a driving cylinder, the cylinder body of the driving cylinder is fixedly connected to the mounting plate, and the piston rod of the driving assembly is fixedly connected to the abutment plate.

[0013] According to one embodiment of the present invention, a guide plate for guiding the piston rod of the drive cylinder is fixedly provided on the mounting plate.

[0014] According to one embodiment of the present invention, the lower mold is provided with a guide slope on the discharge side to guide the finished product discharge of the push rod fork.

[0015] The advantages and beneficial effects of this utility model are as follows: The push rod fork deburring component of this utility model is reasonably designed. By setting a chamfering component and a limiting component on the discharge side of the progressive die for forming the push rod fork, when the progressive die is closed, the burr edge of the bottom edge of the finished push rod fork is chamfered and squeezed away by the chamfering component. When the finished push rod fork is discharged from the progressive die, it is a burr-free product, avoiding subsequent deburring operations and improving production efficiency.

[0026] like Figure 1-7As shown, the push rod fork deburring assembly of the embodiment includes a push rod fork forming progressive die 1, a chamfering assembly, and a limiting assembly. The push rod fork forming progressive die 1 includes a support platform 11 and a cutting assembly. The support platform 11 is used to support the finished push rod fork 2 and the push rod fork material strip 3 when the die is closed. The cutting assembly is used to cut the finished push rod fork 2 off the push rod fork material strip 3. The chamfering assembly is disposed on the discharge side of the cutting assembly. The chamfering assembly includes an arc-shaped chamfer 4 fixedly disposed on the support platform 11. The arc-shaped chamfer 4 abuts against the burr edges of two adjacent finished push rod fork 2. The arc-shaped chamfer 4 is used to squeeze and remove the burr edges when the die is closed. The limiting assembly is disposed on the discharge side of the chamfering assembly. The limiting assembly cooperates with the cutting assembly to fix the position of the finished push rod fork 2 when the die is closed.

[0027] Since the cutting assembly removes the waste material from top to bottom, the burrs are generated on the bottom edge of the push rod fork and will not protrude too much, because the rounded chamfer 4 is sufficient to squeeze and remove the burr edge.

[0028] According to one embodiment of the present invention, the push rod fork forming progressive die 1 includes a fixedly disposed lower die 12 and a liftingly disposed upper die 13, and the support platform 11 is fixedly connected to the lower die 12.

[0029] According to one embodiment of the present invention, the cutting assembly includes a punching blade 5, which is fixedly connected to the upper mold 13. The punching blade 5 is provided with a cutting edge 51 for punching waste material and an abutting surface 52 that abuts against the side wall of the push rod fork finished product 2.

[0030] This design allows the contact surface 52 of the punch 5 to abut against the finished push rod fork 2 during mold closing. When combined with the limiting component, the position of each individual finished push rod fork 2 can be fixed, preventing it from sliding to both sides due to the squeezing of the arc chamfer 4 during deburring operations.

[0031] According to one embodiment of the present invention, the limiting component includes an abutment plate 6 that abuts against the side wall of the push rod fork finished product 2, a driving component that drives the abutment plate 6 to abut against or separate from the push rod fork finished product 2, and a mounting plate 7 that is fixedly connected to the lower mold 12. The driving component is connected to the mounting plate 7.

[0032] With this design, when the mold is closed, the drive component drives the abutment plate 6 to abut against the push rod fork finished product 2 and cooperates with the abutment surface 52 of the punching blade 5 to fix the position of the push rod fork finished product 2.

[0033] According to one embodiment of the present invention, the driving assembly includes a driving cylinder 8, the cylinder body of the driving cylinder 8 is fixedly connected to the mounting plate 7, and the piston rod of the driving assembly is fixedly connected to the abutment plate 6.

[0034] According to one embodiment of the present invention, a guide plate 71 for guiding the piston rod of the drive cylinder 8 is fixedly provided on the mounting plate 7.

[0035] According to one embodiment of the present invention, the lower mold 12 is provided with a guide slope 121 on the discharge side to guide the discharge of the finished product 2 of the push rod fork.

[0036] With this design, in the mold-opening state, as the push rod fork material belt 3 advances, the push rod fork finished product 2 located on the discharge side is pushed towards the discharge side, and slides down from the guide slope 121 to complete the discharge of the push rod fork finished product 2.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
