Description

Automatic lifting and feeding mechanism for bar stock of material rack

Technical Field

The utility model relates to an automatic lifting and feeding mechanism for a rack bar stock.

Background

The existing bar feeding mechanisms are various, and the most main purpose is to lift bars from low positions to high positions, so that the required height and required posture are realized, and the requirements of stacking, transferring and production are met. There are also many forms of lifting from low to high, such as random lifting of the link plate type, lifting of single material of the guide rail type, rotating lifting of the hook type, lifting of the push plate type step, etc. However, these lifts have a common feature in that manual loading of bars into a magazine at the front end of the mechanism is required. In actual production, the working procedures after cutting are to store and transport bars by using material frames with various specifications. After the material frame is transferred in place, the material in the material frame is manually stacked in the lifting mechanism, so that the labor is wasted and the labor efficiency is low.

In actual production, the worker needs to take out one or more bar materials from the material rack slowly, put the bar materials into the material bin of the push plate feeding machine, take out and put the material after the bar materials of the material bin are processed, the bar materials passing through the hand of each day are more than 10 tons, the labor intensity is high, and full-time feeding staff is needed.

Detailed Description

An automatic lifting and feeding mechanism for a rack bar stock, as shown in fig. 1, comprises: work or material rest dolly 1, work or material rest 2, mounting plate 3, pneumatic cylinder subassembly 4, lifting mechanism mount 5, sliding component 6, push pedal material loading machine 7, left direction subassembly 8, right direction subassembly 9 etc. wherein: the material rack 2 filled with the bars is placed on the material rack trolley 1, and the material rack 2 is fixed through a limiting device on the material rack trolley 1. Above the material rack 2, a movable left guide component 8 and a movable right guide component 9 are arranged, when the material rack 2 is placed on the material rack trolley 1, the left guide component 8 and the right guide component 9 can be placed on the material rack 2, and then the trolley is pushed into the lifting mechanism. The material rack trolley 1 is placed on the mounting bottom plate 3, the bottom plate of the hydraulic cylinder assembly 4 and the lifting mechanism fixing frame 5 are fixed on the mounting bottom plate 3 in a welding mode, and the sliding assembly 6 capable of moving up and down is arranged in the guide groove of the fixing frame 5. The upper part of the sliding component 6 is fixedly connected with the upper part of the hydraulic cylinder component 4 through screws. A push plate feeding machine 7 for feeding in the next process is arranged on the left side of the fixed frame 5.

As shown in fig. 2, the lifting part is composed of a sliding component 6, a limiting device 10 and a guide groove 11, wherein the limiting device 10 and the guide groove 11 are fixed on a lifting mechanism fixing frame 5 in a welding mode, the limiting device 10 limits the trolley, and the trolley can not move upwards due to friction force of the bar stock and the material frame under the action of the limiting device 10 in the lifting process of the sliding component 6. The slide assembly 6 is slidable up and down in the guide groove 11.

As shown in fig. 3, the sliding component 6 is composed of a lifting plate 12, a longitudinal roller 13, a transverse roller 14, a fixed seat 15, a fixed plate 16, a connecting bracket 17 and a pressing cushion block 18. The sliding component is fixedly connected by a connecting bracket 17 formed by welding channel steel, and is connected with the hydraulic cylinder component 4 through screws, so that the sliding component can move up and down. The connecting bracket 17 is fixedly provided with the lifting plate 12 through the connecting block and the screw, the lifting plate 12 is directly contacted with the bar stock in the lifting process, the lifting effect is achieved, and the upper surface of the connecting bracket is provided with a certain inclination angle, so that the bar stock can be conveniently rolled into the stock bin smoothly after the lifting is finished. The fixing plate 16 is fixed with the connecting bracket 17 through a pressing cushion block 18. The fixed plate 16 is provided with a fixed seat 15 and a longitudinal roller 13, and the fixed seat 15 is provided with a transverse roller 14. The longitudinal roller 13 and the transverse roller 14 roll in the guide groove 11 and have the functions of front, back, left, right guide and limit.

As shown in fig. 4, after the trolley with the material rack 2 is pushed into the lifting mechanism, the trolley is fixed by the limiting device 10, and under the power action of the hydraulic cylinder, the sliding component 6 moves upwards to drive the bar 19 in the material rack to move upwards. When the bar is lifted to a certain height and the uppermost bar is higher than the left guide component 8, the bar can only roll into the bin of the push plate feeding machine 7 along the inclined plane of the sliding plate 23 of the left guide component due to the fact that the right guide component 9 is higher, when the lifting mechanism lifts a little (the lifting distance is controlled according to production requirements), the material on the sliding component 6 is less until the upper surface of the lifting plate 12 of the sliding component 6 is completely higher than the upper end of the left guide component 8, and the bar can roll into the push plate feeding machine 7 along the inclined plane of the lifting plate 12 completely, as shown in fig. 5.

The structure of the material rack trolley 1 is shown in fig. 6, and comprises a material rack roller assembly 20 and a material rack limiting movable plate 21, wherein the material rack roller assembly 20 is used for supporting a material rack, and the material rack limiting movable plate 21 is used for limiting the material rack.

The structure of the material rack 2 is shown in fig. 7, the material rack is made of hollow square tubes, and the hollow holes 22 of the main brackets on the two sides are used for placing left and right guide assemblies.

The left guide assembly 8 is structured as shown in fig. 8, including a slide plate 23 and a leg 24.

The right guide assembly 9 is constructed as shown in fig. 9 and includes a limit stop 25 and a leg 26.

When the left and right guide assemblies are mounted on the rack, the height of the limit baffle 25 of the right guide assembly is higher than that of the slide plate 23 of the left guide assembly.

The working principle of the utility model is as follows:

(1) At the outer end of the automatic lifting mechanism for the bar stock of the material rack, the material rack 2 filled with the bar stock is placed on the material rack trolley 1, the material rack is fixed through a material rack limiting movable plate 21 on the material rack trolley, and then the material rack trolley 1 is pushed into the lifting mechanism. (2) The material rack trolley in the pushing lifting mechanism is limited up and down through the limiting device 10 arranged on the lifting mechanism, and the material rack trolley is still at the bottom and can not move along with the lifting mechanism in the upward movement process of the lifting mechanism, so that the bar stock is in a freely movable state. (3) Under the action of hydraulic cylinder power, the sliding component 6 moves upwards to drive the bar in the material rack 2 to move upwards, and the material rack and the trolley cannot move along with the lifting of the bar. (4) When the bar is lifted to a certain height and the uppermost bar is higher than the height of the sliding plate 23 of the left guide assembly, the bar rolls into a designated bin along the inclined plane of the sliding plate, and the right bar is restrained by the right guide assembly, so that the bar can only move leftwards.
