Example 1
As shown in fig. 1 and 2, a highway protective net bearing component processing apparatus includes:
a powered core piece 100 for inserting a sleeve-like profile and carrying it down to the stamping zone;
a lower die part 200 which is arranged below the power die core piece 100 and sequentially punches the cylindrical profile on the power die core piece 100 from the bottom to the two sides of the bottom;

and an upper die part 400 which is arranged above the cylindrical section bar synchronously shifted to the inquiring midpoint of the positioning part 300 and shifts the top of the cylindrical section bar to the original center of the cylindrical section bar by one side for traction and stamping.
From the above, it is found that in the process of producing the anti-blocking block for processing the bearing component of the road protection network, particularly the cylindrical section bar, the cylindrical section bar is directly inserted and sleeved on the power mold core piece 100, and then the bottom-up press forming treatment of the cylindrical section bar without welding is realized.
It should be noted that, when the bottom and two sides of the bottom of the cylindrical section are formed by punching, the power mold core piece 100 moves down onto the lower mold portion 200, then on the lower mold portion 200, the bottom of the cylindrical section is first contacted with the lower mold portion 200, after punching, two sides are moved to punch the bottom two sides of the cylindrical section, so that the material when the cylindrical section is punched into the anti-blocking block is sequentially processed from bottom to top, when the upper mold portion 400 is used for punching, friction between the material and each position of the mold is reduced, and when the upper mold portion 400 is used for punching, since the bottom and two sides of the cylindrical section are far from the upper mold portion 400, the bottom and two sides of the cylindrical section are firstly punched in advance by the lower mold 200, and the punching space for extruding the multi-output section to the upper mold portion 400 can be realized.
It should be further noted that, as shown in fig. 9 and 10, when the top and the top sides of the cylindrical section after the stamping of the lower die portion 200 are stamped, because the extrusion of the excess material is extruded to the space between the top and the top sides of the cylindrical section under the stamping of the lower die portion 200, and the top sides of the cylindrical section are irregularly offset toward a certain side, the offset directions of the top and the top sides of the cylindrical section are located and queried by the locating portion 300, and are located to the midpoint position between the top sides of the cylindrical section, and the initial stamping position of the upper die portion 400 is adjusted according to the midpoint position, and then the top and the top sides of the cylindrical section are stamped by the upper die portion 400 based on the initial stamping position, and when the query center is moved downward, the cylindrical section is gradually moved toward the center point of the power core member 100 just sleeved with the cylindrical section before being stamped, and the center point can be understood as the center point of the top die member 100, so that the top and the top sides of the cylindrical section at the offset positions are pulled, and the top sides of the cylindrical section tend to be stamped by a relatively small amount, and the top sides of the cylindrical section tends to be stamped by a relatively small amount, and the top sides of the top sides tend to be stamped when the top and the top sides are stamped is much more easily.
As shown in fig. 6, the lower mold part 200 includes:
