Description

Technical Field

[0001] The utility model relates to the technical field of sampling shears, in particular to a sampling shear press head device. Background Art

[0002] The sampling shear is a key equipment for quality inspection on the hot-rolled sheet continuous casting and rolling production line. The hot plate coil is transported by the coiler to the sampling shear roller table. When uncoiling and shearing for sampling, the leading end extends in an arc shape, which endangers the safety of the inspection personnel and affects stacking. Therefore, it is necessary to set a press head for straightening to a certain extent for visual inspection of quality and stacking.

[0003] The press head device in the existing technology is driven by a hydraulic cylinder. Due to the characteristics of the hot rolling process, the temperature of the steel coil is still about 700°C when it reaches the sampling shear. As the hydraulic cylinder continuously drives the press head, due to the lack of conventional means for limiting and fixing, the press head line will be abnormal, causing the hydraulic cylinder pipeline to rupture, and sometimes causing oil leakage, which may cause a fire at high temperature, bringing major safety hazards to the safety of operators and equipment.

[0004] In view of this, it is necessary to propose a sampling shear press head device to solve or at least alleviate the above defects. Content of the Utility Model

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0034] Please refer to the attached Figures 1-5, an example of a sampling shear head device provided by the present utility model includes a mounting mechanism 10, a head mechanism 20, a guiding mechanism 30, and a driving assembly 40. First of all, it should be noted that the lateral direction in this application refers to the length direction of the mounting plate 120 in the mounting mechanism 10, and specific instructions can be referred to in the attached drawings; different from the prior art where the head device uses a hydraulic cylinder for driving, due to the characteristics of the hot rolling process, the temperature of the steel coil is still about 700 °C when it reaches the sampling shear. As the head is continuously driven by the hydraulic cylinder, it is prone to swing due to the instability of the conventional limit fixing means, which sometimes causes oil leakage in the oil circuit and may cause a fire at high temperatures, bringing major safety hazards to the safety of operators and equipment. This application solves the above defects in the prior art by providing a sampling shear head device, specifically as follows:

[0035] The mounting mechanism 10 is used to be fixed on the sampling shear frame. The mounting mechanism 10 has a guiding channel 111 extending vertically. The guiding mechanism 30 is movably arranged vertically in the guiding channel 111, and the bottom end of the guiding mechanism 30 extends out of the guiding channel 111; the bottom end of the guiding mechanism 30 is connected to the head mechanism 20. The connecting end of the driving assembly 40 is connected to the outer side wall of the mounting mechanism 10, the driving end of the driving assembly 40 is connected to the head mechanism 20, and the head mechanism 20 is detachably arranged.

[0036] Specifically, the sampling shear head device in this application includes a mounting mechanism 10, a head mechanism 20, a guiding mechanism 30, and a driving assembly 40. The mounting mechanism 10 is used for installing the guiding mechanism 30 and fixing the entire device on the sampling shear frame, and it can be connected by bolts for easy disassembly and assembly; the head mechanism 20 is used for straightening the slab, and the guiding mechanism 30 is used to drive the head mechanism 20 to move up and down, and at the same time can limit the movement trajectory of the head straightening of the head mechanism 20 to avoid deviation; the driving assembly 40 is used to drive the head mechanism 20 and the guiding mechanism 30 to move. As a power source, in conventional technical means, the head mechanism 20 uses a hydraulic cylinder, which has a risk of oil leakage and may cause accidents in the environment of the sampling shear. Therefore, in a preferred embodiment of this application, since most of the hot rolled coils are thin slabs, the driving assembly 40 can use a cylinder to be applied to the process of producing thin slabs. The required head force is small, so it is different from the hydraulic cylinder and does not have a pipeline of hydraulic oil, and instead uses industrial compressed air, which is relatively safe.

[0037] Among them, the installation mechanism 10 has a guiding channel 111 for installing the guiding mechanism 30, and the guiding channel 111 extends vertically to limit the limiting direction of the guiding mechanism 30 to be vertical. In this way, it can also be perpendicular to the slab surface, improving the straightening efficiency of the press head. When the press head mechanism 20 moves vertically, the guiding mechanism 30 also moves along the guiding channel 111 (vertically), thus achieving the effect of limiting and guiding. Therefore, the guiding mechanism 30 needs to be movably arranged vertically in the guiding channel 111, and its bottom end extends out of the guiding channel 111 for easy connection with the press head mechanism 20. When the driving assembly 40 drives the press head mechanism 20 to press down flatly, it will not swing randomly under the limitation of the guiding assembly, and the pipeline of the driving assembly 40 will not be loosened due to random swinging, resulting in leakage, and the connection is more reliable.

[0038] As a preferred embodiment of the present invention, the press head mechanism 20 includes a press head block 210, and the press head block 210 is recessed inward to form a connection groove 211. The bottom end of the press head mechanism 20 is inserted into the connection groove 211, and a first connection hole communicating with the connection groove 211 is opened at the bottom of the press head block 210. The press head block 210 is fixedly connected to the press head mechanism 20 by a bolt passing through the first connection hole and extending into the bottom end of the press head mechanism 20.

[0039] It should be noted that the press head block 210 is a component for the press head, and its interior is recessed to form a connection groove 211 for installing and connecting the bottom end of the press head mechanism 20. After the bottom end of the press head mechanism 20 is inserted into the connection groove 211, the first connection hole at the bottom of the connection groove 211 can be used for bolt connection and fixation. In this way, it is convenient to disassemble and assemble when the press head block 210 needs to be replaced, facilitating later replacement and maintenance.

[0040] As a relatively optimal embodiment of the present invention, the press head mechanism 20 further includes a contact plate 220 and a shoulder pin 230. The contact plate 220 protrudes upward to form two fixing plates 221 arranged oppositely along the transverse direction. The two fixing plates 221 are respectively arranged on both sides of the press head block 210, and through holes are opened on the fixing plates 221. Blind holes corresponding to the through holes are opened on the side wall of the press head block 210. The contact plate 220 is connected to the press head block 210 by the shoulder pin 230 passing through the through hole and extending into the blind hole; a second connection hole corresponding to the first connection hole is opened at the bottom of the contact plate 220. The press head block 210 is fixedly connected to the press head mechanism 20 by a bolt sequentially passing through the first connection hole, the second connection hole and extending into the bottom end of the press head mechanism 20.

[0041] It should be noted that the contact plate 220 is used to directly contact the slab. Its square plate form can increase the contact area with the slab, thereby improving the flattening and straightening efficiency. The fixing plate 221 convexly formed on the contact plate 220 is used to connect the contact plate 220 with the press head block 210. It can be connected through the shoulder pin 230. The shoulder pin 230 has a significant positioning effect, can bear a large axial force without deforming the axial parts, and at the same time does not require additional supporting parts. Only the through hole of the fixing plate 221 and the blind hole of the press head block 210 need to be set in the form corresponding to the shoulder pin 230, that is, the diameter of the blind hole is smaller than that of the through hole but coaxial, so as to connect the contact plate 220 with the press head block 210 through the shoulder pin 230. Since the contact plate 220 is in direct contact with the flattening, it is a vulnerable part. When it needs to be replaced, it can be disassembled and replaced through the shoulder pin 230, which is convenient to operate. Considering that adding the contact plate 220 also needs to facilitate the fixing of the press head mechanism 20 by bolts, therefore, a second connection hole corresponding to the first connection hole is also opened at the bottom of the contact plate 220 for the bolt to penetrate. The corresponding setting here means that the first connection hole and the second connection hole have the same size and quantity and are coaxial.

[0042] As a preferred embodiment of the present invention, the guiding mechanism 30 includes a guiding column 310. The guiding channel 111 is arranged to match the guiding column 310. The guiding column 310 is vertically movably arranged in the guiding channel 111, and the bottom end of the guiding column 310 abuts against the connecting groove 211. The press head block 210 is fixedly connected to the guiding column 310 by a bolt passing through the first connection hole and extending into the bottom end of the guiding column 310.

[0043] It is worth noting that the guiding column 310 can be set in a cylindrical shape, so the guiding channel 111 can also be set as a cylindrical channel matching the guiding column 310 to ensure the sliding limit effect of the guiding column 310. Therefore, for the convenience of connecting the guiding column 310 and the press head block 210, the connecting groove 211 of the press head block 210 can also be correspondingly set in the form of a circular cross-section. In this way, when connecting, only the bottom of the guiding column 310 needs to be inserted into the connecting groove 211 and then connected by bolts from the bottom.

[0044] As a preferred embodiment of the present invention, the guiding mechanism 30 further includes an orientation sleeve 320. The orientation sleeve 320 is arranged inside the bottom of the guiding channel 111 and sleeved on the guiding column 310. The orientation sleeve 320 is convexly provided with a flange surrounding itself. The flange is provided with mounting holes arranged at intervals in the circumferential direction. The flange is fixedly connected to the mounting mechanism 10 by bolts passing through the mounting holes and extending into the mounting mechanism 10.

[0045] It should be noted that the orientation sleeve 320 is used to further play the role of limiting and guiding the guide post 310, and is filled and arranged between the guide post 310 and the inner side wall of the mounting mechanism 10. Therefore, it is sleeved on the guide post 310, and a flange surrounding itself is convexly provided thereon for connection with the mounting mechanism 10. The orientation sleeve 320 is fixedly arranged at the bottom of the guide channel 111 by means of bolts.

[0046] Furthermore, the guiding mechanism 30 further includes two guiding keys 330 arranged oppositely along the transverse direction. A guiding groove 331 matching the guiding keys 330 is recessed on the side wall of the guide post 310, and the guiding keys 330 are fixed in the guiding groove 331 by bolts;

[0047] The orientation sleeve 320 is provided with an orientation groove 321 for the guiding keys 330 to penetrate through. The top of the connecting groove 211 further has a key groove 212 for installing the guiding groove 331. The guiding keys 330 penetrate through the orientation groove 321 and abut against the key groove 212.

[0048] It should be noted that the guiding keys 330 can play a guiding role. Since the orientation sleeve 320 is fixed and immovable, after penetrating through the orientation groove 321 on the orientation sleeve 320, the rotation of the guiding keys 330 can be restricted to further achieve the effect of limiting and guiding; the guiding keys 330 can be connected to the guide post 310 by means of bolt connection. The guiding groove 331 recessed on the guide post 310 is used for installing the guiding keys 330. Since the bottom of the guide post 310 is inserted into the connecting groove 211, a key groove 212 is formed in a circular shape outward at the top of the connecting groove 211 for the guiding keys 330 to be inserted and abutted against. Thus, the connecting groove 211 is arranged in a shape similar to a step at this time.

[0049] Furthermore, the guiding mechanism 30 further includes a mounting spacer 340, and the mounting spacer 340 is arranged inside the top of the guide channel 111 and sleeved on the guide post 310.

[0050] It should be understood that the mounting spacer 340 has a similar function to the orientation sleeve 320, and is used to further play the role of limiting and guiding the guide post 310 at the top of the guide channel 111. By sleeving on the guide post 310, it is also filled and arranged between the guide post 310 and the inner side wall of the mounting mechanism 10,

[0051] Further, the installation mechanism 10 includes a guiding frame 110 and a mounting plate 120. The mounting plate 120 is used to be fixed on the sampling shear frame. The mounting plate 120 is connected to the side wall of the guiding frame 110, and the guiding frame 110 has the guiding channel 111.

[0052] It should be noted that the guiding frame 110 is used for installing the guiding column 310, and it can adopt the form of a rectangular column. The mounting plate 120 is used to be fixed on the sampling shear frame, and the mounting part can adopt the bolt connection method for easy disassembly and assembly.

[0053] Further, two first ear plates 112 which are oppositely arranged in the transverse direction are convexly provided on one side of the guiding frame 110 away from the mounting plate 120. Two second ear plates 213 which are oppositely arranged in the transverse direction are convexly provided on one side of the pressing head away from the mounting plate 120. The connecting end of the driving assembly 40 is connected between the two first ear plates 112, and the driving end of the driving assembly 40 is connected between the two second ear plates 213.

[0054] It can be understood that considering the structural characteristics at both ends of the driving assembly 40 (cylinder) of the general model, ear plates are added to facilitate the installation and connection of the cylinder. The first ear plate 112 is used for connecting the top end of the driving assembly 40 (cylinder), and the second ear plate 213 is used for connecting the bottom end of the driving assembly 40 (cylinder). After connecting the top and bottom ends of the driving assembly 40 (cylinder) to the ear plates through a pin shaft, a clamping plate (not shown in the figure) can be provided at the pin shaft to limit its rotation to ensure the fixed installation of the driving assembly 40 (cylinder).

[0055] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
