Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a roller coating unit. Background Art

[0002] Metallurgical machinery and equipment generally have the characteristics of complex structure, large size, and high precision requirements. They often work continuously under high temperature, heavy load, dusty and corrosive conditions; therefore, some equipment needs to be replaced frequently, such as rollers, coating rollers, bearings, etc. In particular, for equipment that needs to be accurately positioned and frequently replaced, safe and efficient equipment maintenance is particularly important, which is of great significance for shortening process time, ensuring product quality, and improving the economic benefits of the enterprise. At the same time, it saves a lot of manpower and reduces labor intensity. Adding a maintenance station within the same equipment frame can meet such needs. During normal production, the equipment is in the online position; when maintenance is required, the equipment moves to the maintenance position for operation; after maintenance, the equipment moves to the working position to participate in production.

[0003] Since the equipment switches between the working position and the maintenance position, in order not to affect normal production, the equipment must be accurately positioned and quickly unlocked at the working position, and the positioning operation space is usually relatively small. Figure 1 , the 1# roller coating car and the 2# roller coating car are arranged in series in the running direction of the strip steel. Each roller coating car can be switched between the working position and the inspection and maintenance position. The translation direction of the roller coating car is perpendicular to the running direction of the strip steel. The roller coating car needs to be locked or unlocked by the positioning parts when it is in the working position and the maintenance position.

[0004] The current conventional method is to manually operate the positioning parts such as latches. Due to the small size and large number of positioning parts, it is time-consuming and laborious to complete the disassembly and assembly work in a short period of time, and it is highly dangerous to operate next to the equipment; especially the positioning parts on the outlet side of the 1# roller coating car and the inlet side of the 2# roller coating car have basically no operating space for installation, and manual operation is not allowed next to the machine.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The embodiment of the present invention provides a roller coating unit, including a plurality of roller coating vehicles 9 arranged in series along the running direction of the strip steel, each of the roller coating vehicles 9 can be translated and switched between its own working position and maintenance position, and the specific structure of the roller coating vehicle 9 is not described here. At least one group of positioners for locking the roller coating vehicle 9 is respectively provided between each two adjacent working positions and between each two adjacent maintenance positions, and it is further preferred to provide multiple groups. Taking the positioner between two adjacent working positions as an example, among the multiple groups of positioners between the two working positions, some positioners are used to lock one of the roller coating vehicles 9, and the remaining positioners are used to lock the other roller coating vehicle 9. Furthermore, the entrance and exit ends of each working position are respectively provided with multiple positioners; the entrance and exit ends of each maintenance position are respectively provided with multiple positioners.

[0028] Since the space between two adjacent working positions / two adjacent maintenance positions is relatively narrow, it is not convenient to install the positioning member 6. The above-mentioned positioner is preferably a positioner suitable for automatic operation, specifically:

[0029] like Figure 2-Figure 9The positioner comprises a positioning seat 3, a positioning member 6, a first guide slide 5 and a double-sided inclined wedge block 1, wherein the positioning seat 3 is slidably arranged on the first guide slide 5, the positioning member 6 is arranged at the front end of the positioning seat 3, and the positioning seat 3 is provided with a bearing drive groove for the double-sided inclined wedge block 1 to extend into, and the bearing drive groove has two bearing drive surfaces arranged in sequence along the sliding direction of the positioning seat 3, and both of the bearing drive surfaces are inclined surfaces having an angle with the sliding direction of the positioning seat 3;

[0030] The double-sided inclined wedge block 1 is connected to a wedge block driving unit 7, so as to have: a first direction stroke in which one of its wedge surfaces slides on one of the bearing drive surfaces until the double-sided inclined wedge block 1 gradually enters the bearing drive groove, at the end of the first direction stroke, the positioning seat 3 is close to the corresponding roller coating vehicle 9 and the positioning member 6 is inserted into the positioning notch of the roller coating vehicle 9; and a second direction stroke in which the other wedge surface slides on the other bearing drive surface until the double-sided inclined wedge block 1 gradually withdraws from the bearing drive groove, at the end of the second direction stroke, the positioning seat 3 is away from the corresponding roller coating vehicle 9 and the positioning member 6 is disengaged from the positioning notch of the roller coating vehicle 9.

[0031] It is easy to understand that the first guide slide 5 is used to guide the positioning seat 3 to approach or move away from the corresponding roller coating vehicle 9, that is, to guide the positioning member 6 to approach or move away from the corresponding roller coating vehicle 9, so as to realize the operation switching of the positioning member 6 between the locking position and the unlocking position. The first guide slide 5 can adopt a conventional slide rail structure, and the sliding structure of the positioning seat 3 on the first guide slide 5 is also a conventional technology, which will not be described in detail here.

[0032] The positioning member 6 is used to match the positioning notch on the roller coating vehicle 9, and can be a positioning pin, such as a conical pin, a cylindrical pin or a wedge pin.

[0033] The above-mentioned wedge block driving unit 7 is used to drive the double-sided inclined wedge block 1 to perform linear reciprocating motion, that is, the above-mentioned first direction stroke is opposite to the second direction stroke, but the stroke space is shared; conventional linear driving equipment is suitable for this embodiment, for example, hydraulic cylinders, air cylinders, electric push rods, screw lifts, etc. can be used.

[0034] Obviously, the above-mentioned two bearing drive surfaces are used to cooperate with the two wedge surfaces of the double-sided inclined wedge block 1 respectively to achieve the purpose of operating switching of the positioning member 6 between the locking position and the unlocking position. Among the two bearing drive surfaces, one bearing drive surface is a locking bearing drive surface for making the positioning member 6 run to the locking position, and the other bearing drive surface is an unlocking bearing drive surface for making the positioning member 6 run to the unlocking position; the two wedge surfaces of the double-sided inclined wedge block 1 are correspondingly a locking wedge surface and an unlocking wedge surface; the two bearing drive surfaces can be but are not limited to a parallel relationship, but preferably they are parallel to each other, so as to facilitate multiple cycles to realize the state switching of the positioning member 6; in addition, preferably, the locking bearing drive surface is parallel to the locking wedge surface, and the unlocking bearing drive surface is parallel to the unlocking wedge surface.

[0035] The structural relationship between the double-sided inclined wedge block 1 and the bearing drive groove can satisfy the following conditions, which can be easily designed by those skilled in the art:

[0036] When the locking wedge surface of the double-sided inclined wedge block 1 contacts the locking bearing surface of the bearing groove and slides on the locking bearing surface (for example, the double-sided inclined wedge block 1 runs in the first direction stroke at this time), the positioning member 6 gradually approaches the corresponding roller coating vehicle 9 until the positioning member 6 is inserted into the positioning notch of the roller coating vehicle 9;

[0037] When the unlocking wedge surface of the double-sided inclined wedge block 1 contacts the unlocking bearing drive surface of the bearing drive groove and slides on the unlocking bearing drive surface (for example, the double-sided inclined wedge block 1 runs in the second direction stroke at this time), the positioning member 6 gradually moves away from the corresponding roller coating vehicle 9 until the positioning member 6 disengages from the positioning notch of the roller coating vehicle 9.

[0038] exist Figure 2 and Figure 3 In the illustrated embodiment, the bearing and driving groove is directly formed on the positioning seat 3 .

[0039] exist Figure 4-Figure 9 In the illustrated embodiment, a positioning ball 4 is installed on the positioning seat 3 in the form of a spherical hinge, and the bearing drive groove is provided on the positioning ball 4. The positioning ball 4 is installed on the positioning seat 3 and the two constitute a ball joint pair. Accordingly, the positioning seat 3 constitutes the ball seat of the ball joint pair, and a ball bowl is provided on the positioning seat 3. The positioning ball 4 is installed in the ball bowl to constitute a ball joint pair. Since the positioning ball 4 is hinged on the positioning seat 3, it has a universal movable characteristic. Therefore, in the initial state, when the locking bearing drive surface is not parallel to the locking wedge surface / the unlocking bearing drive surface is not parallel to the unlocking wedge surface, after the double-sided inclined wedge block 1 contacts the positioning ball 4, the positioning ball 4 can adaptively make the locking bearing drive surface parallel to the locking wedge surface / the unlocking bearing drive surface parallel to the unlocking wedge surface. Based on the universal movable characteristics of the positioning ball 4, the double-sided inclined wedge block 1 has a wide selection of installation orientations, so it can better adapt to the working conditions of different installation spaces, especially it can solve the problem that the space between two adjacent workstations of the roller coating unit is small and it is not easy to install the positioning member 6, and better realize the operation switching of the positioning member 6 between the locking position and the unlocking position. In one embodiment, the double-sided inclined wedge block 1, the positioning seat 3 and the positioning member 6 are located in the same plane, for example, the double-sided inclined wedge block 1 is arranged on the sliding plane where the positioning seat 3 is located, and they are all arranged on the same plane of the roller coating machine frame 8; in another embodiment, the double-sided inclined wedge block 1 is arranged outside the sliding plane where the positioning seat 3 is located, for example, the positioning seat 3 and the positioning member 6 and the roller coating machine are located in the same horizontal plane, and the double-sided inclined wedge block 1 is located above the positioning seat 3.

[0040] In another embodiment, a turntable structure may be used to replace the positioning ball 4, that is, a positioning turntable is rotatably embedded on the positioning seat 3, and the bearing drive groove is opened on the positioning turntable, which can also obtain better application effects, which will not be described in detail here.

[0041] More preferably, if Figure 2-Figure 9 The double-sided inclined wedge block 1 includes a first rod segment and a second rod segment, the first rod segment is connected to the wedge block driving unit 7 and its length direction is parallel to the linear driving direction of the wedge block driving unit 7, and two wedge surfaces of the double-sided inclined wedge block 1 are formed on the second rod segment and have an angle with the length direction of the first rod segment. The double-sided inclined wedge block 1 of this structure is easy to arrange, and is convenient for the cooperation between the second rod segment and the positioning seat 3. In addition, the first rod segment can be extended according to the surrounding space conditions, which is convenient for the arrangement of the wedge block driving unit 7.

[0042] Furthermore, if Figure 2-Figure 9 The above-mentioned positioner also includes a second guide slide 2, the first rod segment is slidably arranged on the second guide slide 2, the guiding direction of the second guide slide 2 is the same as the linear driving direction of the wedge block driving unit 7, and the linear reciprocating motion of the double-sided inclined wedge block 1 is guided by the second guide slide 2 to ensure the smooth operation of the double-sided inclined wedge block 1, thereby ensuring the accuracy of the positioning and locking of the positioning member 6.

[0043] The angle between the linear reciprocating stroke direction of the double-sided inclined wedge block 1 and the linear reciprocating stroke direction of the positioning seat 3 can be any angle, such as Figure 2-Figure 9 , showing the situation where the linear driving direction of the wedge block driving unit 7 forms an acute angle, a right angle or an obtuse angle with the sliding direction of the positioning seat 3. In the case where the double-sided inclined wedge block 1 is arranged outside the sliding plane of the positioning seat 3, for example, when the double-sided inclined wedge block 1 is arranged directly above the linear reciprocating path of the positioning seat 3, the linear driving direction of the wedge block driving unit 7 and the sliding direction of the positioning seat 3 can also be parallel to each other.

[0044] Further preferably, the above-mentioned positioner is also equipped with a position detection mechanism for detecting the position of the positioning member 6, so as to ensure the accuracy of the positioning and locking operation of the positioning member 6 on the roller coating vehicle 9. Figure 2-Figure 9In one embodiment, the position detection mechanism includes two first detection elements, the two first detection elements are a structure of a proximity switch and a sensing block, wherein one first detection element 10 is mounted on the positioning seat 3, and the other first detection element 11 is mounted beside the sliding path of the positioning seat 3, and satisfies: when the positioning member 6 is in the locked position, the two first detection elements are in a state of mutual induction, and when the positioning member 6 is in other positions (that is, the positioning member 6 is separated from the positioning notch of the roller coating vehicle 9, and the positioning member 6 is in the unlocked position), the two first detection elements are in a non-inductive state. Of course, it can also be set that when the positioning member 6 is in the locked position, the two first detection elements are in a non-inductive state, and when the positioning member 6 is in the unlocked position, the two first detection elements are in a state of mutual induction.

[0045] In another embodiment, the above-mentioned purpose can also be achieved by detecting the linear reciprocating motion of the double-sided inclined wedge block 1. Specifically, the position detection mechanism includes two second detection elements, which are a structure that cooperates with a proximity switch and a sensing block. One of the second detection elements is installed on the double-sided inclined wedge block 1, and the other second detection element is installed beside the sliding path of the double-sided inclined wedge block 1, and it satisfies the following conditions: when the positioning member 6 is in the locked position, the two second detection elements are in a mutually inductive state, and when the positioning member 6 is in other positions, the two second detection elements are in a non-inductive state.

[0046] The position of the positioning member 6 is detected by the position detection mechanism, so as to guide the action of the wedge drive unit 7 and ensure automatic control.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
