Description

Forging stock conveying device for stamping steel balls

Technical Field

The invention belongs to the technical field of auxiliary facilities of steel ball punch forming equipment, and particularly relates to a forging stock conveying device for punching steel balls.

Background

The aforementioned forged billet is also referred to as a bar stock or a bar segment (the same applies hereinafter). The process of steel ball punch forming is roughly as follows: the steel round bar as raw material is firstly introduced into a heating furnace for heating, then the heated steel round bar is cut into forging stock according to the volume of the steel ball to be formed, and the forging stock is conveyed to a steel ball stamping forming machine by a forging stock conveying device to be stamped and formed into the steel ball.

From the above description and in conjunction with the expert knowledge, it can be ascertained without doubt: the forging stock conveying device is positioned at a forging stock forming station and a steel ball punch forming station in a use state, namely, the forging stock conveying device alternately moves between the forging stock forming station and the steel ball punch forming station according to the rhythm of process requirements.

The prior forging stock conveying device for stamping steel balls is characterized in that a screw (namely a lead screw) is driven by a servo motor and a sliding table is driven by the screw to move between the two stations, and the speed of the movement mode is relatively slow, so that the device cannot adapt to a high-speed steel ball stamping forming machine, and a servo motor control system is complex, high in cost and high in daily inspection and maintenance cost. The "apparatus for transporting a workpiece by a forging press" proposed in CN203109155U and the "feeding robot for a hot forging line" provided in CN102581197A have technical effects described in the technical effect column of the specification, but they have the drawbacks described above because they both use the servo motor.

The "forged steel ball conveying device for stamping steel balls" introduced in CN108326225A, because of eliminating the servo motor, makes up the aforementioned disadvantages of CN203109155U and CN102581197A and can objectively reconcile the four advantages summarized in the technical effect column of the specification, but still has the following disadvantages: firstly, when a forging stock is fed into a steel ball stamping forming machine, the whole sliding table carrying a forging stock clamping and placing mechanism is required to be displaced to a lower die frame of the steel ball stamping forming machine together (together), so that one end of a front cross beam and a rear cross beam of a sliding table frame of a structural system of the sliding table frame, which are used for the sliding of the sliding table, facing the steel ball stamping forming machine is reliably fixed with the steel ball stamping forming machine, certain influence can be generated on the structural integrity and the reasonability of the steel ball stamping forming machine, and certain influence can be generated on the safety protection of related parts; secondly, because a clamping and placing mechanism bearing table (called a sliding table) provided with a forging blank clamping and placing mechanism (namely a forging blank clamping and placing manipulator) can only move left and right but cannot lift, the lifting height of the clamping and placing mechanism bearing table which cannot lift can only be compensated by opening and closing (descending when opening and rising when closing or retracting) of the forging blank clamping and placing mechanism (called a forging material clamping and placing mechanism), so that the movement amplitude of the forging blank clamping and placing mechanism in the opening and closing process is larger, especially as mentioned above, because the sliding table carries the part of a lower die carrier which advances and retreats to the steel ball stamping forming machine, the stamping forming machine must be kept enough between the upper die carrier and the lower die carrier to meet the opening and closing space of the forging blank clamping and placing mechanism, otherwise, an interference situation occurs, and the steel ball stamping machine is added with a harsh factor to a certain extent; thirdly, after the forging stock is pushed out by the forging stock pushing mechanism, the forging stock needs to be pushed upwards by the forging stock pushing mechanism to feed the forging stock to the forging stock clamping mechanism, so that the structure is relatively complex, the space occupation is large, and the daily convenient inspection and maintenance is not facilitated. In view of the foregoing, and not by way of limitation, there is a need for improvement and the solutions described below are made in this context.

Then, the forging stock clamping/releasing manipulator driving cylinder 61 is operated in the reverse direction to repel the first clamping jaw i 836 and the second clamping jaw ii 837 of the forging stock clamping/releasing manipulator 83 of the forging stock clamping/releasing mechanism 8, that is, to release the clamping of the forging stock 10 in the lower mold 92. Then, the above-described process is repeated to drive the working cylinder 56 by the left and right shuttles, thereby moving the blank holding and releasing mechanism support 7 leftward, i.e., in a direction away from the upper and lower dies 91, 92. The above process is repeated continuously to achieve the desired rate of feeding the forging stock 10 into the upper and lower dies 91, 92. Furthermore, as can be seen from the schematic illustration of fig. 5, the structure of the present invention is not structurally connected with the steel ball stamping forming machine 9, so that the two have good integrity and independence respectively.

In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
