Description

Technical Field

[0001] This utility model relates to the field of ball cage cage processing technology, specifically a punching processing device for a DO section type ball cage cage. Background Technology

[0002] The ball cage is a component of the ball cage universal joint, while the cage connects the inner and outer raceways and the steel balls, ensuring the stability and lifespan of the steel balls during transmission. Traditional ball cage cages are manufactured using a punching machine to ensure that they are connected between the vehicle's tires and differential for transmitting driving force.

[0003] The invention disclosed in CN108436180A is a ball cage cage pull hole clamp. By using the downward movement of the broach of the broaching machine, the grooved wheel is rotated at a fixed angle through the crank connecting rod mechanism, thereby driving the ball cage cage base to rotate. This achieves automatic rotation, which not only avoids the uncertainty of manual rotation, but is also more efficient and convenient.

[0004] However, the above-mentioned punching fixture for ball cage cages still has the following problems in actual use: Although the vertical rotation punching is achieved by the crank connecting rod, the punch shank and punch head are punched within the inner diameter of the workpiece. The overhang of the punch head end has no upper support force. During the shearing process, the cage wall thickness is more than twice that of other cages. The support of the punch shank tail end cannot bear the punching force of the cage wall thickness. The unilateral force causes the punch shank to bend during the force process, and the punch head tilts to shear, which causes the life of the punch shank, punch head and punch shank sleeve to drop rapidly. In addition, the workpiece has bright bands and tear bands, and the punch head is difficult to demold and has roughening phenomena.

[0005] Therefore, we propose a punching device for DO-section ball cage cages to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a punching device for a DO-section ball cage retainer. This device addresses the problems of existing rotary punching processes that achieve vertical rotation via a crank and connecting rod, where the punch shank and punch head are punched within the workpiece's inner diameter. The punch head end is overhanging and lacks upper support. During the shearing process, the retainer wall thickness is more than twice that of other retainers, and the support from the tail end of the punch shank cannot bear the punching force of the retainer wall thickness. Unilateral force causes the punch shank to bend during the force process, and the punch head to tilt and shear, resulting in a rapid decrease in the lifespan of the punch shank, punch head, and punch shank sleeve. Furthermore, it causes problems such as bright bands, tear bands on the workpiece, difficulty in punch demolding, and roughening.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a punching device for a DO-section ball cage retainer, comprising a bearing base and a support assembly fixedly installed on the top surface of the bearing base;

[0008] A punch press working plate is provided above the bearing base, and the punch press working plate is connected to the punch press hydraulic components. A support shaft is fixedly provided at the right end of the bottom surface of the punch press working plate; it also includes:

[0009] A punch handle sleeve is provided on the upper left side of the bearing base, and the punch handle sleeve is fixedly installed on the top of the support assembly.

[0010] Preferably, the top surface of the punch sleeve is provided with a die core assembly, and the die core assembly is in contact with the punch work plate above the bearing base to improve the uniformity of force distribution.

[0011] Preferably, the punch sleeve has a punch body inside, and the punch sleeve improves the force balance of the punch body, avoiding tilting and bending due to unidirectional force on the punch body during the punching process.

[0012] Preferably, a planar bearing is provided on the left side of the bearing base, and the planar bearing is installed at the right end of the punch sleeve, and the right end of the punch body inside the punch sleeve passes through the interior of the planar bearing.

[0013] Preferably, a reference ring is provided at the right end of the punch sleeve, and the left end of the reference ring is located inside the plane bearing and fixedly connected to the right outer wall of the punch sleeve. The reference ring, the plane bearing, and the punch body are distributed concentrically.

[0014] Preferably, a die body is provided on the upper right side of the support base, and the die body is fixedly installed on the top right side of the support assembly. A material dropping slot is provided at the center of the die body so that the waste material after the frame is punched can fall down.

[0015] Preferably, a spring clip is provided on the upper right side of the bearing base, and a through-hole is provided on the upper left end of the spring clip. The retainer is fixed and installed on the right end of the reference ring by the spring clip, and the support shaft passes through the through-hole to form a synchronous force on both ends.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This DO-section ball cage cage punching device punches the ball cage cage through a double support method, extends the punch shank and adds a punch shank sleeve, so that the punch shank sleeve ensures the stability of the punch shank body. At the same time, a support shaft is set on the bottom surface of the punch press work plate so as to position the ball cage cage after passing through the spring clip, thereby achieving force balance of the punch shank body. The specific details are as follows:

[0017] 1. The ball cage retainer is limited by the punch body that runs through the punch sleeve, so that the left end of the ball cage retainer is in contact with the outer wall of the plane bearing and the reference ring, thereby achieving positioning and calibration of the ball cage retainer and preventing displacement during subsequent punching process;

[0018] The ball cage retainer is locked and positioned by a spring clip and a reference ring, and is attached to the punch press work plate by a die core assembly above the support assembly. The support shaft on the right side of its bottom surface is inserted through a through hole opened inside the left end of the spring clip, and then abuts against the upper right end of the ball cage retainer, thereby achieving balanced positioning and improving stability under force.

[0019] 2. The punch shank body is positioned by the punch shank sleeve, which ensures the stability of the punch shank sleeve. When it moves to the right, the ball cage retainer is punched. The scrap material that is separated from the ball cage retainer moves with the punch shank body to the top of the die body and falls down through the blanking slot opened inside the die body to discharge the scrap material and improve the punching efficiency.
