Description

Technical Field

[0001] The present application relates to the technical field of cold shears, and in particular to a material pushing structure of a cold shear. Background Art

[0002] Cold shear, also known as cold shear, is a heavy machine used to shear rolled materials or rolled products at room temperature.

[0003] During the shearing process, after the cold shear cuts off the ends of the material, the cut ends will fall into the waste collection pit. After a group of rolled materials are cut to length, the remaining tails are at the front end of the cold shear, so a pushing mechanism is needed to push the tails into the collection pit.

[0004] For example, the patent with announcement number CN108246805B discloses a cold shear pushing device. This patent realizes the function of automatic steel pushing by utilizing the linkage between the main driving part, the connecting rod and the push rod, and uses the push head installed at one end of the push rod to push the tail of the material, thereby improving the efficiency of the cold shear; the main driving part is connected to the drive control system, which can realize remote automatic operation of the device, and accordingly greatly reduces the safety hazards in the area; the steel picking and pushing efficiency is high, which can reduce the labor intensity of workers and save production costs.

[0005] However, during the shearing process of the cold shearing machine, the blade passes through the rolled material at an extremely high speed, generating strong friction and extrusion. This friction and extrusion may cause tiny particles on the surface of the material to be peeled off and form debris. When the debris falls on the shearing platform, they may come into contact or rub against the next set of rolled materials to be sheared, which will cause the rolled materials to deflect or deform during the shearing process, thereby affecting the shearing accuracy.

[0006] Therefore, it is necessary to provide a cold shear pushing structure to solve the above problems.

[0007] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the Invention

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] like Figure 1-Figure 3As shown, the present application provides a cold shear pushing structure, including a transport platform 1, which is used to transport the rolled material and guide it into the shearing area. At the same time, in order to push the sheared tailings into the collection pit, a pushing mechanism 2 is fixedly provided on the upper end of the transport platform 1, and the pushing mechanism 2 is used to push the tailings into the collection pit for use;

[0036] The pushing mechanism 2 includes a bracket 20 fixedly mounted on the upper end of the transport platform 1, a mounting plate 21 fixedly mounted on the upper end of the bracket 20, a first cylinder 22 fixedly mounted on the upper end of the mounting plate 21, and an output end of the first cylinder 22 passes through the mounting plate 21 and is fixedly connected to a fixing plate 24;

[0037] At the same time, a plurality of first guide rods 23 are slidably provided on the mounting plate 21, and the other ends of the first guide rods 23 are fixedly connected to the fixing plate 24, so that the first cylinder 22 is activated to push the fixing plate 24 to move vertically under the guidance of the first guide rods 23;

[0038] A second cylinder 27 is fixedly provided at the lower end of the fixed plate 24, and a mounting bar 28 is fixedly provided at the output end of the second cylinder 27. At the same time, a plurality of second guide rods 26 are slidably provided around the lower end of the fixed plate 24 and the second cylinder 27. One end of the second guide rod 26 is fixedly connected to the mounting bar 28. When the second cylinder 27 is activated, the mounting bar 28 is pushed to move along the transport direction under the guidance of the second guide rod 26.

[0039] When the rolled material is being transported, the first cylinder 22 drives the fixed plate 24 to be in a raised state. When the rolled material is sheared to the last cut and the remaining material is not enough for the fixed length, the first cylinder 22 pushes the fixed plate 24 vertically downward. The fixed plate 24 stops when it is lowered to 5 mm above the transport plane. Then the second cylinder 27 is started to push the mounting bar 28 from left to right under the guidance of the second guide rod 26 to the shear blade position. At this time, the tailings at the shear blade position can be pushed into the waste pit.

[0040] like Figure 3-Figure 5 As shown, in order to collect the debris generated during shearing when the second cylinder 27 drives the mounting bar 28 to retract to the initial position after the tailings are pushed into the waste pit, thereby preventing the residual debris from affecting the next set of shearing, a flap assembly 29 is fixedly provided on the mounting bar 28. The flap assembly 29 is used to collect the debris generated during shearing while pushing the tailings;

[0041] The flap assembly 29 includes a housing 293 fixedly mounted on the mounting bar 28. A third cylinder 296 is fixedly mounted on the upper end of the housing 293. A rack 294 is fixedly mounted on the output end of the third cylinder 296. A gear 292 is rotatably mounted on the lower end of the housing 293. The gear 292 is meshed with the rack 294. Thus, when the third cylinder 296 is activated, the rack 294 is pushed to move vertically along the housing 293. During the movement, the gear 292 is driven to rotate within the housing 293.

[0042] At the same time, a stopper 295 is fixedly provided inside the housing 293. The stopper 295 is located at the lower end of the rack 294 so that when the third cylinder 296 pushes the rack 294 downward, it stops moving until it touches the stopper 295. At this time, the rack 294 can drive the gear 292 to rotate 90 degrees inside the housing 293.

[0043] A push plate 290 is fixedly provided on one side of the gear 292. The push plate 290 is used to push the tailings. A scraper bar 291 is fixedly provided on the upper end of the push plate 290. The scraper bar 291 is used to scrape the debris when returning. The scraper bar 291 is tilted to facilitate scraping the debris.

[0044] After the push plate 290 pushes the tailings into the waste pit under the push of the second cylinder 27, the rack 294 can be pushed vertically upward along the cover 293 by activating the third cylinder 296. At this time, the rack 294 drives the gear 292 to rotate around the cover 293, and at the same time drives the push plate 290 to flip, so that the scraper 291 on the upper end of the push plate 290 is in contact with the transport platform 1.

[0045] Then, the second cylinder 27 drives the push plate 290 to reset, and the scraper 291 collects the debris during the reset, so as to carry out centralized processing;

[0046] At the same time, a discharge port 3 is opened on the transport platform 1 at the initial position of the pushing mechanism 2, and the discharge port 3 is used to discharge the collected debris for use, and a temporary storage box 4 is fixedly provided at the lower end of the discharge port 3, and the temporary storage box 4 is used to store the discharged debris for use;

[0047] After the reset is completed, the first cylinder 22 drives the fixing plate 24 to rise vertically to a high position under the guidance of the first guide rod 23, and finally the next set of cut materials continues to be transported to the shearing position.

[0048] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
