Technical Field

The invention relates to the technical field of scraped car disassembly equipment, in particular to scraped car roof rapid flattening equipment.

Background

With the development of automobile technology and the improvement of living standard of people, the consumption of automobiles is more and more large, and simultaneously, a large number of automobiles are scrapped every year, wherein various parts become solid wastes, which brings huge negative influence to the environment, and the scrapped automobiles are mainly made of materials such as steel, nonferrous metals, plastics, rubber, glass and the like.

For storage and transportation, the automobile needs to be initially crushed after being scrapped to reduce the occupied volume. With the development of society, consumers pay more and more attention to their life safety, and the safety of automobiles is also higher and higher. The maximum pressure that can be withstood by the roof of a vehicle is included in a crash test for checking the safety of the vehicle. The larger the maximum pressure which can be borne by the roof of the automobile is, the more the integrity of the passenger compartment of the automobile can be maintained when the automobile rolls over in an accident, and the life safety of people in the automobile is protected.

Therefore, when an automobile manufacturer designs and produces, the passive safety performance of the automobile body is improved by optimizing the structural design and manufacturing the automobile body frame by adopting materials with higher yield limit (such as hot-forming steel or even carbon fiber to replace high-strength steel and ultrahigh-strength steel), so as to obtain the favor of consumers. But on the other hand also increases the difficulty of compressing the scrapped car after it has been scrapped. The applicant finds that the difficulty of crushing the scraped car is more and more increased along with the time in the actual dismantling operation of the scraped car, and the crushed car often needs to be repeatedly crushed for a plurality of times in recent years to obtain the same crushing effect in the past. It is even necessary to renew the crushing plant and to use a more pressurized crushing plant for the crushing operation. Resulting in reduced processing efficiency or additional equipment upgrade costs.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a scrap car roof rapid-flattening apparatus provided by the present invention.

The quick flattening equipment for the scraped car roof comprises: the device comprises an equipment rack 1, a flattening mechanism 2, a lateral bending mechanism 3 and a lifting mechanism 4.

The equipment rack 1 includes a bottom plate 11, side plates 12, and a top plate 13. The top plate 13 is connected with the top of the side plate 12, and the top plate 13 and the side plate 12 are connected to form a working area in which the scraped car is compressed. The bottom plate 11 is disposed directly below the top plate 13. The floor 11 is used to carry the scraped car and avoid it crushing the ground when it is crushed. The base plate 11 can be made of steel in general.

The crushing mechanism 2 includes a platen 21 and a first hydraulic cylinder 22. The fixed end of the first hydraulic cylinder 22 is connected with the top plate 13, the movable end of the first hydraulic cylinder extends vertically downwards to be connected with the pressing plate 21, and the pressing plate 21 is arranged right above the bottom plate 11. The first hydraulic cylinder 22 can drive the pressing plate 21 to reciprocate up and down to crush the scraped car. The contact surface of the pressing plate 21 and the scraped car, namely the lower surface, is serrated, so that the integrity of the top of the scraped car is further damaged in the compression process, and the flattening difficulty is reduced. The hydraulic cylinder 22 may be replaced with other mechanisms for reciprocating up and down, but in the preferred embodiment, the hydraulic cylinder 22 is preferably used from the viewpoint of providing a large amount of pressure and cost of the equipment. While other reciprocating mechanisms (e.g., air cylinders, cam linkages) are designed to achieve the same amount of force, the complexity and cost of the apparatus is much higher than that of hydraulic cylinders.

The two lateral bending mechanisms 3 are symmetrically arranged on two sides of the bottom plate 11 and are used for bending the B-pillar of the scraped car. The A column, the B column and the C column of the automobile are commonly called modes defined by the automobile industry, and refer to three pillars which are used for connecting the roof and the lower automobile body on one side of the car, and the pillars are respectively the A column, the B column and the C column along the direction from the automobile head to the automobile tail. Namely, two sides of a car are respectively provided with an A column, a B column and a C column.

In the present embodiment, each lateral bending mechanism 3 includes a bending head 31 and a second hydraulic cylinder 32, wherein the fixed end of the second hydraulic cylinder 32 is connected to the side plate 12, and the movable end thereof is connected to the bending head 31. The second hydraulic cylinder 32 is disposed horizontally and drives the bending head 31 to move horizontally in the horizontal direction. Similar to the first hydraulic cylinder 22, the second hydraulic cylinder 32 may be replaced with another reciprocating mechanism, but a hydraulic cylinder mechanism is preferably used in combination. The two bending heads 31 are arranged opposite to each other, and the ends thereof remote from the second hydraulic cylinders 32 project outwards in a zigzag shape with an included angle of 45 ° to 90 °, of which 60 ° is preferred.

The lifting mechanism 4 is connected with the bottom plate 11 and used for changing the position of the bottom plate 11 in the vertical direction so that the bending head 31 is opposite to the proper position of the B column of the scraped car. In the actual use process, the bending head 31 is generally opposite to the middle part of the B column of the scraped car to bend the B column. The lifting mechanism 4 can also adopt a hydraulic cylinder mechanism to realize the function of longitudinal displacement.

When the scraped car is flattened, the scraped car is firstly placed on the bottom plate 11, and then a worker can judge whether the B column needs to be bent according to the brand and the model of the scraped car. Generally speaking, the higher the price of the vehicle, the better the brand, the later the year of production and manufacture, the better the passive safety performance, i.e. the higher the proportion of the high yield limit hot formed steel adopted in the frame, whereas the lower-cost automobile body generally adopts a large amount of high strength steel or ultra-high strength steel with lower yield limit, and the B-pillar bending process is not needed, and the B-pillar can be directly flattened by the flattening mechanism 2. The worker can accumulate experience of whether the vehicle needs the heat treatment for the B-pillar in long-term work to obtain the best treatment result.

When the operator judges that the B column needs to be bent, the lifting mechanism 4 is adjusted to enable the bending head 31 to be over against a proper position on the B column of the scraped car. Then, the two second hydraulic cylinders 32 are controlled to drive the bending heads 31 to move towards each other, so that the B column is bent. And the scrapped automobile body is compressed downwards by the compression flat mechanism 2, so that the difficulty of compressing the scrapped automobile is effectively reduced, the compression efficiency is improved, the extra overhead of updating larger compression equipment is avoided, and the equipment cost is reduced.

And the technical scheme that this embodiment provided can directly carry out upgrading transformation on the present scrap car flattening equipment, under the condition that does not change equipment rack 1 and the flattening mechanism 2 of flattening equipment, directly increases lateral bending mechanism 3 and carries out horizontal striking bending to scrap car's B post, and the transformation mode is simple and easy and low cost. Meanwhile, the method adopts the mode that the stress core B columns in the A column, the B column and the C column of the three supporting columns of the bearing roof in the automobile are deformed into the zigzag shape to reduce the capability of the automobile for resisting the pressure from the direction of the roof by pre-bending, so that the pressure of the existing hydraulic cylinder 22 with originally insufficient pressure is sufficient and a part of pressure margin is obtained after the efficiency of the B column of the scraped automobile is greatly reduced, the structural strength development rate of the existing automobile is estimated, after the existing scraped automobile flattening equipment is upgraded and modified according to the method provided by the scheme, the pressure provided by the hydraulic cylinder 22 of the existing scraped automobile flattening equipment can be sufficiently used in a quite long end time, namely, the crushed and upgraded scraped automobile flattening equipment can be used for a long time, and the method has good economic benefit.

The embodiment of the invention has the following beneficial effects: the quick flattening equipment for the scraped car roof firstly impacts the side surface of the B column through the bending mechanism to bend the B column so as to reduce the yield strength of the B column along the vertical direction, and then downwards compresses a scraped car body through the pressing mechanism, so that the B column is further deformed along the bending direction after being bent by longitudinal force, the difficulty of compressing the scraped car is effectively reduced, the compression efficiency is improved, the extra expense of updating larger compression equipment is avoided, and the equipment cost is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
