Abstract
The utility model belongs to the technical field of forging technologies of automobile parts and specifically discloses a connecting fork forged blank for a universal joint. The connecting fork forged blank comprises a sleeve and a fork body, wherein the sleeve and the fork body are molded by forging forged round steel or square steel once; fork heads are symmetrically arranged at the two ends of the fork body, and smooth inclined planes are arranged on the inner sides of the fork heads at the two ends; gaps are symmetrically arranged at one end of the sleeve, and the diameter of the gap on one side is larger than that of the gap on the other side; and the diameter of a pipe body of the sleeve is larger than the fork body diameter of the fork body. The connecting fork forged blank disclosed by the utility model ensures the quality of a finished product of a connecting fork of the universal joint, prolongs the service life, reduces the using risk safety coefficient, and further reduces the manufacturing cost and the investment; and simultaneously, the connecting fork forged blank disclosed by the utility model has the advantages of low production cost and easiness in popularization.
Description
Technical field
The utility model belongs to the auto parts and components technical field of forging, is specifically related to a kind of universal joint and forges blank with clevis.
Background technique
Known from institute, the automobile clevis is mainly used in various transmission shafts and is connected with the steering gear in the connection, and utilization rate is the highest on universal joint, one of component important in the automobile assembling work, it specifically plays transmitting torque, adjust the effect of various transmission shafts, the steering gear and universal joint, and make perfectly cooperation between the various component, thereby make automobile at the middle acquisition power that advances.
The semi-finished product clevis base substrate that adopts prior art to forge is real chipware, needing again, the fine finishing of process secondary drilling is finished product, because carrying out secondary fine processing boring to semi-finished product clevis base substrate, increased by a procedure, not only waste material on the one hand, increased the manufacture cost input, if misoperation also affects product qualified rate greatly when carrying out on the other hand secondary fine processing boring; The internal surface tightness of simultaneously secondary fine processing boring is lower, very big reduced the working life of clevis and has increased the application risk safety coefficient.
Therefore, based on the problems referred to above, the utility model provides a kind of universal joint to forge blank with clevis.
The model utility content
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, provide a kind of universal joint to forge blank with clevis, guarantee universal joint clevis end product quality, increase working life, reduce the application risk safety coefficient, further also reduce manufacture cost and drop into.
Technological scheme: a kind of universal joint forges blank with clevis, comprises sleeve pipe and fork body, and described sleeve pipe and fork body are by forging round steel or forging molding of square steel.
The two ends of preferred described fork body are symmetrically arranged with jaw, and wherein the jaw inboard at two ends is set to smooth ramp.
Preferred described sleeve pipe one end is symmetrical arranged jagged, and wherein the notch diameter of a side is greater than the notch diameter of opposite side.
The pipe diameter of preferred described sleeve pipe protrudes from the fork body diameter of fork body.
Compared with prior art, the beneficial effects of the utility model are:
This universal joint forges blank with clevis and has the following advantages: it is one-body molded 1, to forge the blank middle sleeve at the universal joint clevis, has not only saved steel and has saved follow-up secondary fine procedure, also reduces enterprise's manufacture cost and drops into; 2, be set to smooth ramp in the inboard, two ends of fork body, increased the working efficiency of the component that are attached thereto; 3, make easier for installation and do not affect safe handling at the symmetrically arranged breach of sleeve pipe one end; Simultaneously low, the easy popularization of the utility model cost of production.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Wherein, sequence number is as follows among the figure: 1-sleeve pipe, 2-fork body, 3-jaw, 4-breach.
Embodiment
Below in conjunction with specific embodiment a kind of universal joint described in the utility model being forged blank with clevis elaborates:
A kind of universal joint as shown in Figure 1 forges blank with clevis, comprises sleeve pipe 1 and fork body 2, and described sleeve pipe 1 and fork body 2 are by forging round steel or forging molding of square steel.
The two ends of preferred fork body 2 are symmetrically arranged with jaw 3, and wherein jaw 3 inboards at two ends are set to smooth ramp.
It is jagged 4 that preferred sleeve pipe 1 one ends are symmetrical arranged, and wherein the notch diameter of a side is greater than the notch diameter of opposite side.
The pipe diameter of preferred sleeve pipe 1 protrudes from the fork body diameter of fork body 2.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
