Description

Technical Field

[0001] This utility model relates to the field of flying shear device technology, specifically a hub-type high-speed flying shear device resistant to thermal deformation. Background Technology

[0002] Traditional bar shears have upper and lower blades mounted on corresponding upper and lower blade arms. During operation, the upper and lower blade arms drive the upper and lower blades to rotate relative to each other. When the upper and lower blades mesh together, one bar shearing operation is completed.

[0003] When a high-speed rotating hub and shears come into close contact with a high-temperature workpiece, they absorb a large amount of heat, causing their own temperature to rise rapidly. Due to differences in materials, structures, and the degree of heating, components such as the hub, cutter head, and bearing housing will experience uneven thermal expansion. This directly leads to the following: the preset reasonable shearing blade gap (usually very small) increases or becomes uneven due to thermal deformation, resulting in large shearing burrs, uneven cuts, and even "blade-biting" accidents. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A heat-resistant, rotating hub-type high-speed flying shear device includes a flying shear mechanism and a cooling mechanism. The flying shear mechanism includes a rotating hub, a heat compensation block inserted into the rotating hub, and shears fixed to the bottom of the rotating hub. The cooling mechanism includes three water flow chambers opened inside the rotating hub, insert boxes inserted into the water flow chambers, an opening opened at the rear of the insert boxes, a hollow cylinder fixed between the three insert boxes, a tube penetrating the rear end of the hollow cylinder, multiple through holes opened on the tube, a sealing sleeve rotatably sleeved at the rear end of the tube, and a water inlet pipe penetrating one side of the sealing sleeve. The through holes are located inside the sealing sleeve.

[0007] By adopting the above technical solution, when the hub is running, external cold water is introduced into the inside of the sealing sleeve through the water inlet pipe. Then, the cold water enters the inside of the insert through the through hole. The cold water flows through the hollow cylinder, the insert box, and the opening in sequence into the water flow chamber. The cold water directly acts on the hub, reducing the probability of thermal expansion of the hub, greatly avoiding shear displacement, and ensuring product quality during shearing.

[0008] In a preferred embodiment, the present invention can be further configured such that the water flow cavity is U-shaped, and the insert box communicates with the interior of the water flow cavity through an opening.

[0009] In a preferred embodiment, the present invention can be further configured as follows: three water flow chambers are equally spaced and arranged in a ring, and the inner wall of the water flow chambers is coated with a hydrophobic coating.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple through holes are equally spaced and arranged in a ring, and the sealing sleeve communicates with the interior of the insert through the through holes.

[0011] In a preferred embodiment, the present invention can be further configured such that: the rear end of the sealing sleeve is vertically flush with the rear end of the insert, and the insert box, hollow cylinder, insert, through hole and sealing sleeve are all made of stainless steel.

[0012] In a preferred embodiment, the present invention can be further configured such that a gap is formed between the rear side of the hollow cylinder and the front side of the sealing sleeve.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the rotating hub is running, external cold water is introduced into the inside of the sealing sleeve through the water inlet pipe. Then, the cold water enters the inside of the insert through the through hole. The cold water flows through the hollow cylinder, the insert box, and the opening in sequence into the water flow chamber. The cold water directly acts on the rotating hub, reducing the probability of thermal expansion of the rotating hub, greatly avoiding shear displacement, and ensuring product quality during shearing.

[0015] 2. In this utility model, the thermal expansion coefficient of the thermal compensation block is much smaller than that of the rotating hub. Therefore, the thermal compensation block can effectively resist the deformation of the rotating hub and further reduce the shear displacement of the wall surface. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a hub-type high-speed flying shear device resistant to thermal deformation.

[0027] Example 1:

[0028] Combination Figure 1-5 As shown, the present invention provides a heat-resistant rotating hub type high-speed flying shear device, including a flying shear mechanism 100 and a cooling mechanism 200. The flying shear mechanism 100 includes a rotating hub 110, a heat compensation block 120 inserted into the rotating hub 110, and a shear 130 fixedly connected to the bottom of the rotating hub 110.

[0029] The cooling mechanism 200 includes three water flow chambers 210 formed inside the rotating hub 110, a plug box 220 inserted into the water flow chambers 210, an opening 230 formed at the rear of the plug box 220, a hollow cylinder 240 fixed between the three plug boxes 220, a plug tube 250 passing through the rear end of the hollow cylinder 240, a plurality of through holes 260 formed on the plug tube 250, a sealing sleeve 270 rotatably sleeved at the rear end of the plug tube 250, and a water inlet pipe 280 passing through one side of the sealing sleeve 270. The through holes 260 are located inside the sealing sleeve 270.

[0030] Furthermore, the water flow chamber 210 is configured in a "U" shape, and the insert box 220 is connected to the interior of the water flow chamber 210 through the opening 230. The shape design of the water flow chamber 210 allows cold water to flow, ensuring the cooling effect of cold water on the rotating hub 110.

[0031] Furthermore, multiple through holes 260 are evenly spaced and arranged in a ring. The sealing sleeve 270 communicates with the inside of the insert 250 through the through holes 260. The through holes 260 are provided to ensure that cold water inside the sealing sleeve 270 can smoothly enter the inside of the insert 250.

[0032] Furthermore, the rear end of the sealing sleeve 270 is vertically flush with the rear end of the insert 250. The insert box 220, hollow cylinder 240, insert 250, through hole 260 and sealing sleeve 270 are all made of stainless steel. Using stainless steel to make the insert box 220, hollow cylinder 240, insert 250, through hole 260 and sealing sleeve 270 can improve their resistance to water erosion.

[0033] Example 2:

[0034] Combination Figure 2-4 As shown, based on Embodiment 1, the three water flow chambers 210 are equally spaced and arranged in a ring. The inner wall of the water flow chamber 210 is coated with a hydrophobic coating. The hydrophobic coating can prevent cold water from corroding the rotating hub 110 and ensure the service life of the rotating hub 110.

[0035] Example 3:

[0036] Combination Figure 2 and Figure 4 As shown, in the above embodiment, a gap is formed between the rear side of the hollow cylinder 240 and the front side of the sealing sleeve 270. The gap is set to ensure that the sealing sleeve 270 will not wear against the rear wall of the hollow cylinder 240 when it rotates.

[0037] The working principle and usage process of this utility model are as follows: In the initial state, the thermal expansion coefficient of the thermal compensation block 120 is much smaller than that of the rotating hub 110. Therefore, the thermal compensation block 120 can effectively resist the deformation of the rotating hub 110. Then, when the rotating hub 110 is running, external cold water is introduced into the sealing sleeve 270 through the water inlet pipe 280. Then, the cold water enters the insert 250 through the through hole 260. The cold water flows through the hollow cylinder 240, the insert box 220, and the opening 230 in sequence into the water flow chamber 210. The cold water directly acts on the rotating hub 110, reducing the probability of thermal expansion of the rotating hub 110, greatly avoiding the displacement of the shears 130, and ensuring the product quality during shearing.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
