Abstract

The utility model provides an automatic rotation upsetting platform, which relates to an intermittent rotation device. The automatic rotation upsetting platform comprises a rotation platform 1, a base 2, a cylinder 3 and a push-pull box 4, wherein a plurality of poking teeth 1-1 are uniformly distributed on the circumference of the rotation platform 1; a guide rail 2-1 and a cylinder base 2-2 are arranged on the base; the push-pull box 4 is provided with a box body 4-1, a return spring 4-2, a pushing block 4-3 and a pin shaft 4-4; the rotation platform 1 can be rotated on the base 2; a cylinder body 3-1 is fixed on the cylinder base 2-2 of the base 2; a cylinder piston rod 3-2 is fixedly connected with the box body 4-1 of the push-pull box 4; and the push-pull box 4 can do reciprocating motion on the guide rail 2-1 under the action of the cylinder 3. In the rotation upsetting platform, a forged piece can be quickly and stably rotated at a constant speed in the upsetting process, so that the quality of the forged piece is ensured, the labor intensity of workers during operation is reduced, the labor environment is improved, the burn danger of the workers is avoided, and production efficiency is improved.

Description

Automatic rotating upset table

Technical field

The utility model relates to whirligig at a kind of intermittence, the particularly a kind of accessory in the forging process.

Background technology

Because the width of the last anvil of forging press is limited; In forging forging processes such as large-scale annulus spare and large-scale dish; The bottom surface of last anvil can't cover the end face of above-mentioned forging fully; So need place forging on the rotating upset table, while rotate forging is forged, so that each part of forging is all evenly forged.At present, the rotation of most of rotating upset tables all relies on manual work to be rotated, and the weight of forging and upset die is very heavy mostly, and it is very even that artificial rotation can not be accomplished, is difficult to guarantee forging quality; And the forging place condition of high temperature, working strength of workers is very big, also will stand hyperthermia radiation, might cause and burn or burn.

Summary of the invention

The utility model is exactly to design for the above-mentioned defective that overcomes the prior art upset die.

The scheme of the utility model is to be the rotating upset table of power with the cylinder, comprising: turntable 1, base 2, cylinder 3, push-and-pull box 4; The circumference of said turntable 1 is provided with equally distributed some moving tooth 1-1, and base is provided with guide rail 2-1 and cylinder block 2-2, and push-and-pull box 4 has box body 4-1, back-moving spring 4-2, pushing block 4-3 and bearing pin 4-4; Said bearing pin 4-4 is used to flexibly connect pushing block 4-3, because the position-limiting action of box body 4-1, pushing block 4-3 can only rotate in box body 4-1 around bearing pin 4-4; Said turntable 1 can rotate on base 2; Cylinder block 3-1 is fixed on the cylinder block 3-2 of base 2; Cylinder piston rod 3-2 is fixedly connected with the box body 4-1 of push-and-pull box 4, and push-and-pull box 4 is moving back and forth on guide rail 2-1 under the effect of cylinder 3, promotes upset die batch (-type) location Rotating with Uniform.

When original state, pushing block 4-3 keeps vertical state under the acting in conjunction of back-moving spring and box body 4-1; When needs let upset die when rotation, the piston rod 3-2 of cylinder travels forward, and promotes whole push-and-pull box 4 and travels forward, and after pushing block 4-3 and moving tooth 1-1 came in contact, turntable 1 began to rotate; Backhaul after the cylinder piston rod 3-2 arrival maximum travel position; Pushing block 4-3 deflects around bearing pin 4-4 after pushing block 4-3 and moving tooth 1-1 come in contact; Final pushing block 4-3 slips over moving tooth 1-1, under the effect of back-moving spring 4-2, recovers vertical state; Cylinder promotes the push-and-pull box once advancing to move back to accomplish actuation cycle one time like this, lets turntable 1 rotate a certain angle.

This intermittence, whirligig can fast, stably be accomplished the work of rotating upset table automatically, guaranteed the quality of forging, had alleviated workman's operations labor intensity, avoided having improved production efficiency because of hyperthermia radiation causes the danger of burning or burning.

The specific embodiment

Combine accompanying drawing that the utility model is specified now.Because the width of the last anvil of forging press is limited; In forging forging processes such as large-scale annulus spare and large-scale dish; The bottom surface of last anvil can't cover the end face of above-mentioned forging; So need place forging on the rotating upset table, while rotate forging is forged, so that each part of forging is all forged uniformly.

The utility model rotating upset table is exactly a forging accessory of realizing above-mentioned Forging Technology, comprising: turntable 1, base 2, cylinder 3, push-and-pull box 4; The circumference of said turntable 1 is provided with equally distributed some moving tooth 1-1, and base is provided with guide rail 2-1 and cylinder block 2-2, and push-and-pull box 4 comprises box body 4-1, back-moving spring 4-2, pushing block 4-3 and bearing pin 4-4.Said bearing pin 4-4 is used to flexibly connect pushing block 4-3, because the position-limiting action of box body 4-1, pushing block 4-3 can only rotate in box body 4-1.Said turntable 1 can rotate on base 2; Cylinder block 3-1 is fixed on the cylinder block 3-2 of base 2; Cylinder piston rod 3-2 is fixedly connected with the box body 4-1 of push-and-pull box 4, and push-and-pull box 4 can move back and forth on guide rail 2-1 under the effect of cylinder 3, and pushing block 4-3 can rotate around bearing pin 4-4.

When original state, pushing block 4-3 keeps vertical state (Fig. 3) under the acting in conjunction of back-moving spring 4-2 and box body 4-1; When needs let upset die when rotation, the piston rod 3-2 of cylinder travels forward, and promotes whole push-and-pull box 4 and travels forward, and after pushing block 4-3 and moving tooth 1-1 come in contact, promotes turntable 1 and begins to rotate (Fig. 4); Backhaul after the cylinder piston rod 3-2 arrival maximum travel position; Pushing block 4-3 deflects around bearing pin 4-4 after pushing block 4-3 and moving tooth 1-1 come in contact, and final pushing block 4-3 slips over moving tooth 1-1 (Fig. 5), under the effect of back-moving spring 4-2; Recover vertical state; Cylinder promotes the push-and-pull box once advancing to move back to accomplish actuation cycle one time like this, lets upset die rotate a certain angle at every turn, cooperates forging press that forging is forged.
