Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum bar hot shearing, in particular to an energy-saving aluminum bar hot shearing device. BACKGROUND

[0002] The aluminum bar is a rod-shaped metal material made of aluminum as the main raw material, which is widely used in many fields such as industry, construction and transportation due to the excellent properties and processing performance of aluminum.

[0003] The aluminum bar hot shearing device is a special equipment for cutting aluminum bars heated to a plastic state to a specified size in the aluminum processing field. It is usually composed of a heating temperature control system, a feeding and positioning mechanism, a shearing execution assembly and an automatic control system. It uses the characteristic of plasticity improvement of aluminum bar in hot state to complete the cutting operation through a shearing knife die driven by hydraulic or mechanical force. The device can accurately control the shearing length, ensure the smoothness of the cut surface, reduce stress and deformation in cold shearing, adapt to the continuous production needs of aluminum bars of different diameters, and is widely used in the blank preparation link before aluminum profile extrusion, thereby improving the subsequent processing efficiency.

[0004] The existing aluminum bar hot shearing equipment often has the phenomenon of uneven cut surface of aluminum bar after hot shearing. Through research on the product and equipment, it is found that because the discharge rack is lower than the feeding rack, the end of the aluminum bar discharged will tilt downward during the cutting process of the cutting head, so that the aluminum bar cannot always maintain the original horizontal state during the cutting process, and finally leads to uneven cut surface of the aluminum bar.

[0005] Moreover, after the existing aluminum bar hot shearing equipment shears the aluminum bar, it needs to push out the sheared aluminum bar and re-melt the uncut aluminum bar. The pushing out of the aluminum bar is generally completed by a sensor cooperating with a push rod. However, since the push rod is placed below the feeding rack, the running state of the push rod cannot be directly observed. Once the sensor or the push rod and its cooperation fail, it cannot be seen in time whether the push rod is working normally, thereby causing the sheared aluminum bar to be unable to be normally pushed out, and the equipment may be damaged during subsequent operation.

[0006] In addition, in the final discharging stage, the current equipment relies on a separate push rod for discharging, and each drive control unit works independently. Such discharging will cause energy waste.

[0007] On this basis, the present application provides an energy-saving aluminum bar hot shearing device to solve the above problems. SUMMARY

A lower cutting tool head 65 is fixedly installed on the inner side of the shearing frame 1 and is misaligned with the upper cutting tool head 13. The above is the prior art of the existing aluminum bar hot shearing device, which will not be repeated here. A side mounting frame 4 is fixedly installed on one side of the shearing frame 1. A first sliding block 6 is slidably connected to the bottom of the side mounting frame 4. An electric push rod 7 is fixedly installed on the first sliding block 6. The electric push rod 7 is connected to a power supply and a controller. An adjusting mounting frame 10 is fixedly installed at one end of the electric push rod 7. A main adjusting plate 29 is slidably connected to one side of the adjusting mounting frame 10. The main adjusting plate 29 is a hollow block-shaped metal. Two symmetrically arranged first adjusting plates 31 are slidably connected to the inner side of the main adjusting plate 29. Each first adjusting plate 31 is slidably connected to the inner side of the main adjusting plate 29 through a rod and a hole. A first limiting spring 30 is fixedly installed between the first adjusting plate 31 and the main adjusting plate 29. The number of the first limiting springs 30 is multiple, and the multiple first limiting springs 30 are evenly arranged. The first limiting spring 30 can limit the first adjusting plate 31 by elastic force. A second adjusting plate 33 is slidably connected to the inner side of each first adjusting plate 31. The second adjusting plate 33 is slidably connected to the inner side of the first adjusting plate 31 through a rod and a hole. A second limiting spring 32 is fixedly installed between the second adjusting plate 33 and the first adjusting plate 31. The number of the second limiting springs 32 is multiple, and the multiple second limiting springs 32 are evenly arranged. The second limiting spring 32 can limit the second adjusting plate 33 by elastic force. A sliding frame 34 is fixedly installed between the two second adjusting plates 33. A lap arc block 36 is fixedly installed at the bottom of the sliding frame 34. The upper surface of the lap arc block 36 is inclined, which can assist in discharging the aluminum bar. A pushing shaft 26 is fixedly connected to the end of the adjusting mounting frame 10. A pushing frame 27 is rotatably connected to the surface of the pushing shaft 26. The pushing frame 27 is a structure composed of a triangular plate and an additional inclined plate. A contact block 28 is fixedly installed on the side of the main adjusting plate 29 close to the pushing frame 27. The contact block 28 is arranged on one side of the additional inclined plate of the pushing frame 27. The pushing frame 27 can push the sliding frame 34, so as to change the extension length of the sliding frame 34. A through hole 38 is formed in the front-rear direction of the main adjusting plate 29. The pushing frame 27 is slidably connected to the inner side of the through hole 38. A limiting sliding groove 35 is formed in the front-rear direction of the sliding frame 34. A limiting sliding block 37 is fixedly installed at the bottom of the inner side of the main adjusting plate 29 and arranged in the limiting sliding groove 35. When the sliding frame 34 slides upward and contacts the limiting sliding block 37, the sliding frame 34 is blocked by the limiting sliding block 37.

[0034] When the aluminum bar is fed and the end of the aluminum bar needs to be supported and limited, the aluminum bar moving forward due to feeding will first push the contact main adjusting plate 29, at this time the contact block 28 on the main adjusting plate 29 contacts the upper end of the pushing frame 27, so that the pushing frame 27 rotates around the pushing shaft 26 as the center, when the pushing frame 27 rotates, the lower end of the pushing frame 27 rotates counterclockwise upward in the through hole 38, at the same time, the pushing frame 27 extrudes the sliding frame 34 and moves upward and backward at the same time, and drives the lap joint arc block 36 to extend upward, supporting and supporting the bottom of the end of the aluminum bar; When the aluminum bar is sheared, the hydraulic rod 2 works, driving the upper mounting frame 3 and the upper cutting tool head 13 to descend, cooperating with the lower cutting tool head 65 staggered with the upper cutting tool head 13 to press down and shear the aluminum bar, in the shearing process, the hydraulic rod 2 drives the whole aluminum bar to descend, and the end of the aluminum bar will also press down the lap joint arc block 36, in the process of pressing down the lap joint arc block 36, cooperating with the elastic tension of the first limiting spring 30, correcting and compensating the inclination of the end of the aluminum bar caused by shearing, at the same time, the descending lap joint arc block 36 drives the extrusion sliding frame 34 to descend, the extrusion sliding frame 34 will contact the inclined surface of the pushing frame 27, but the pushing frame 27 is continuously limited by the contact block 28 at this time, the pushing frame 27 is in a fixed state, on the contrary, the extrusion sliding frame 34 will be pushed backward through the inclined surface of the pushing frame 27, at the same time, driving the lap joint arc block 36 to push backward, according to the increase of the shearing depth and the inclination degree (because the shearing starts from the upper part of the middle section of the aluminum bar, the upper part of the middle section of the aluminum bar is extruded and cut, while the lower part of the middle section of the aluminum bar remains unchanged, which will cause the end of the aluminum bar to incline downward, and this inclination will increase with the increase of the shearing depth), the automatic adjustment increases the lifting support area, and improves the compensation effect; When the extrusion sliding frame 34 descends to disengage the lower end of the pushing frame 27, at this time the aluminum bar is just finished shearing, the extrusion sliding frame 34 is only subjected to the friction force generated by the lap joint arc block 36 pressed down by the end of the aluminum bar at this time, and there is no other constraint force, so through the return force of the second limiting spring 32, the extrusion sliding frame 34 and the lap joint arc block 36 are driven to move forward, at this time a small part of the end of the aluminum bar is still placed on the lap joint arc block 36, and the continuously working hydraulic rod 2 drives the upper cutting tool head 13, the lower support frame 14 and the cut end of the aluminum bar to descend, the cut end of the aluminum bar and the end of the aluminum bar lapped on the lap joint arc block 36 will form a gradually increasing height difference, the greater the height difference, the smaller the friction between the aluminum bar and the lap joint arc block 36, when the height difference reaches a certain amount, the inclination angle of the upper surface of the lap joint arc block 36, the elastic potential energy of the second limiting spring 32 and the gravity of the aluminum bar itself overcome the friction between the lap joint arc block 36 and the end of the aluminum bar, the aluminum bar will slide downward, realizing complete separation from the lap joint arc block 36, and after separation, the lap joint arc block 36 moves to the main adjusting plate 29 direction with the help of the second limiting spring 32, and finally is in the initial state of being stored in the main adjusting plate 29; When the aluminum rod is separated from the main adjusting plate 29 and the lap arc block 36, the extrusion sliding frame 34 connected with the first adjusting plate 31 and the second adjusting plate 33 is no longer constrained by external force at this time, and is quickly reset to the initial state by the potential energy stored in the first limiting spring 30 connected therewith and stretched, thereby preparing for the next shearing.
