Description

Technical Field

[0001] The utility model relates to the technical field of fixing fixtures, in particular to a nozzle cutting fixture structure. Background Art

[0002] In steel production, the molten steel in the tundish is introduced into the crystallizer through an immersion nozzle for cooling and forming. The immersion nozzle is made of refractory sintering materials.

[0003] During the sintering process of the submerged nozzle, a certain deformation will occur and the submerged nozzle will change to different sizes. The submerged nozzle needs to be cut and corrected. The personnel fix the submerged nozzle with a clamp and then perform the cutting operation. After the cutting is completed, the personnel need to take out the submerged nozzle and replace it with a new submerged nozzle that needs to be cut. The manual removal operation of the submerged nozzle by the personnel increases the operating procedures, and the existing clamp structure still has a large room for optimization to reduce the operating procedures. Summary of the invention

[0004] The disclosed embodiment relates to a nozzle cutting fixture structure, in which an upper fixing frame pulls an upper fixing plate to move upward synchronously via a side connecting buckle, and moving the upper fixing plate upward pushes an upper submerged nozzle to roll to one side, thereby eliminating the operation of manually replacing the submerged nozzle, speeding up the replacement of the submerged nozzle, reducing the submerged nozzle removal process, and improving work efficiency.

[0005] In the first aspect of the present disclosure, a water nozzle cutting fixture structure is provided, which specifically includes: a lower fixture seat, an upper fixed plate and an outer guide frame, wherein the upper portion of the lower fixture seat is vertically slid with an upper fixed plate, the upper portion of the lower fixture seat is fixedly provided with an outer guide frame, the upper portion of the lower fixture seat is fixed with an upper telescopic cylinder, the telescopic rod of the upper telescopic cylinder is fixedly connected to the upper fixed frame, the rear portion of the lower fixture seat is slidably connected with a rear limit frame, and the rear portion of the lower fixture seat is threaded with a side tightening screw.

[0006] In at least some embodiments, the head end of the side tightening screw is tightened against the tail limit frame, which is located in the middle of the upper fixed plate and the outer guide frame. The tail limit frame limits the excess length of the submerged water outlet, and the upper inclined surfaces of the upper fixed plate and the front side of the outer guide frame form a V-shaped structure.

[0007] In at least some embodiments, a lower supporting spring is fitted on the bottom of the upper fixing plate, a side connecting buckle is provided on the outer side of the upper fixing plate, and the middle part of the side connecting buckle is rotatably connected to the lower part of the upper connecting frame.

[0008] In at least some embodiments, an outer guiding oblique frame is fixed to the upper part of the lower clamp seat, and the outer guiding oblique frame is located on the outside of the side connecting buckle. The upper part of the outer guiding oblique frame is inclined toward the side of the upper fixed plate, and the upper end of the side connecting buckle contacts with the upper inclined surface of the outer guiding oblique frame, and the upper inclined surface of the outer guiding oblique frame guides the upper end of the side connecting buckle to rotate toward the side of the upper fixed plate.

[0009] In at least some embodiments, the upper connecting frame and the upper fixed frame are fixedly connected. When the upper connecting frame and the upper fixed frame are raised in height synchronously, the lower end of the side connecting buckle engages with the upper fixed plate and is raised synchronously. After the upper fixed plate moves up to push the upper immersion water outlet higher than the outer guide frame, the immersion water outlet rolls to one side of the outer guide frame, and the immersion water outlet moves along the outer inclined surface of the outer guide frame to be exported.

[0010] In at least some embodiments, when the upper end of the side connecting buckle is tilted and rotated once toward the upper fixing plate along the upper part of the outer guiding inclined frame, the lower end of the side connecting buckle is separated from the upper fixing plate, and the raised upper fixing plate moves downward to reset.

[0011] In at least some embodiments, a middle resistance plate is rotatably arranged in the middle of the outer guide frame, and side reset springs are fixed on both sides of the front end of the middle resistance plate. The lower end of the side reset spring is fixedly connected to the lower clamp seat. The side reset spring pulls the front end of the middle resistance plate to tilt downward, and the rear end section of the middle resistance plate is tilted higher than the rear inclined surface of the outer guide frame, and the immersed water outlet is blocked and decelerated by the middle resistance plate.

[0012] The utility model provides a nozzle cutting fixture structure, which has the following beneficial effects:

[0013] The tail limit frame limits the length of the submerged nozzle to ensure the uniform position of the nozzle after placement, making it easier to cut the excess length of the nozzle, eliminating the measurement process for personnel and improving processing efficiency. The displacement of the tail limit frame can adapt to submerged nozzles of different lengths.

[0014] After the immersion nozzle is cut, the upper fixing frame pulls the upper fixing plate through the side connecting buckle to move upward synchronously, and the upper fixing plate is moved up to push the upper immersion nozzle to roll to one side, eliminating the operation of manual replacement of the immersion nozzle and speeding up the replacement of the immersion nozzle.

[0015] The tail end of the middle resistance plate is tilted to decelerate the submerged water inlet rolling on the upper part of the external guide frame, thereby reducing the collision force of the submerged water inlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: Please refer to Figures 1 to 6 :

[0029] The utility model proposes a nozzle cutting fixture structure, comprising: a lower fixture seat 1, an upper fixed plate 2 and an outer guide frame 3, an upper telescopic cylinder 101 is fixed on the upper part of the lower fixture seat 1, the telescopic rod of the upper telescopic cylinder 101 is fixedly connected to the upper fixed frame 102, a tail limit frame 103 is slidably connected to the tail of the lower fixture seat 1, a side tightening screw 104 is screwed on the tail of the lower fixture seat 1, the head end of the side tightening screw 104 is tightened against the tail limit frame 103, the tail limit frame 103 is located in the middle of the upper fixed plate 2 and the outer guide frame 3, the tail limit frame 103 limits the excess length of the submerged nozzle, and ensures that the lengths of submerged nozzles of different lengths on the upper part of the outer guide frame 3 are the same, and the upper inclined surfaces of the upper fixed plate 2 and the front side of the outer guide frame 3 form a V-shaped structure;

[0030] An upper fixing plate 2 is vertically slidably arranged on the upper part of the lower clamp seat 1, a lower supporting spring 201 is fitted on the bottom of the upper fixing plate 2, a side connecting buckle 202 is arranged on the outer side of the upper fixing plate 2, the middle part of the side connecting buckle 202 is rotatably connected with the lower part of the upper connecting frame 203, an outer guiding oblique frame 204 is fixed on the upper part of the lower clamp seat 1, the outer guiding oblique frame 204 is located on the outer side of the side connecting buckle 202, the upper part of the outer guiding oblique frame 204 is inclined toward one side of the upper fixing plate 2, and the side connecting buckle 202 is rotatably connected with the lower part of the upper connecting frame 203. The upper end contacts with the upper inclined surface of the outer guiding inclined frame 204, and the upper inclined surface of the outer guiding inclined frame 204 guides the upper end of the side connecting buckle 202 to rotate toward the side of the upper fixed plate 2. When the upper end of the side connecting buckle 202 tilts and rotates once along the upper part of the outer guiding inclined frame 204 toward the upper fixed plate 2, the lower end of the side connecting buckle 202 separates from the upper fixed plate 2, and the raised upper fixed plate 2 moves down and resets, which will not affect the subsequent placement of the immersion water outlet. An outer guiding frame 3 is fixedly arranged on the upper part of the lower clamp seat 1.

[0031] In the disclosed embodiment, the upper connecting frame 203 and the upper fixing frame 102 are fixedly connected. When the upper connecting frame 203 and the upper fixing frame 102 are raised in height synchronously, the lower end of the side connecting buckle 202 engages with the upper fixing plate 2 and is raised synchronously. After the upper fixing plate 2 moves upward and pushes the upper immersion water outlet above the outer guide frame 3, the immersion water outlet rolls to the side of the outer guide frame 3, and the immersion water outlet moves and is exported along the outer inclined surface of the outer guide frame 3, eliminating the operation of manual replacement of the immersion water outlet by personnel.

[0032] In the embodiment of the present disclosure, a middle resistance plate 301 is rotated in the middle part of the outer guide frame 3, and side reset springs 302 are fixed on both sides of the head end of the middle resistance plate 301. The lower end of the side reset spring 302 is fixedly connected to the lower clamp seat 1. The side reset spring 302 pulls the head end of the middle resistance plate 301 to tilt downward, and the tail end section of the middle resistance plate 301 is tilted higher than the rear side slope of the outer guide frame 3. The immersion water outlet is blocked by the middle resistance plate 301 in the middle part of the outer guide frame 3 to pause and slow down, thereby reducing the rolling speed of the immersion water outlet and reducing the collision between the immersion water outlets.

[0033] Embodiment 2. On the basis of embodiment 1, the middle resistance plate 301 and the side reset spring 302 may not be provided. The rolling speed of the top submerged water outlet can be reduced by reducing the inclination angle of the outer guide frame 3, and the force of rolling collision between the submerged water outlets can be reduced. Alternatively, an upwardly rising inclined surface is provided at the rear end of the outer guide frame 3 to achieve the effect of reducing the rolling speed of the submerged water outlet. The decelerated submerged water outlet directly enters into a larger aggregate box connected to the rear end of the outer guide frame 3.

[0034] The working principle of this embodiment is as follows: the upper fixed plate 2 and the outer guide frame 3 form a V-shaped structure to place the circular tubular immersion nozzle. The rotation of the side tightening screw 104 no longer tightens the tail limit frame 103. The tail limit frame 103 is fitted with one end of the immersion nozzle. The length of the other end of the immersion nozzle protruding from the outside of the outer guide frame 3 is adjusted. The upper telescopic cylinder 101 is shortened to drive the upper fixed frame 102 to descend. The upper fixed frame 102 descends and fits with the upper part of the immersion nozzle for clamping. The outer side of the outer guide frame 3 protruding from the immersion nozzle is cut. The side tightening screw 104 is rotated to limit the tail. The position of the frame 103 is fixed, and the tail limit frame 103 limits the excess length of the submerged nozzle, ensuring that the lengths of submerged nozzles of different lengths at the upper part of the outer guide frame 3 are the same, ensuring the uniformity of the position of the nozzle after placement, facilitating the cutting of the excess length of the nozzle, eliminating the measurement process of personnel, and speeding up the cutting process efficiency. The tail limit frame 103 can adjust the position according to the submerged nozzles of different lengths, making it more convenient to use, and there is no need to set the individual length models of submerged nozzles of different lengths. One fixture can meet the needs of submerged nozzles of different lengths.

[0035] After the immersion nozzle is cut, the upper telescopic cylinder 101 is extended to support the upper fixing frame 102 to move up and away from the immersion nozzle. The upper fixing frame 102 and the side connecting buckle 202 and the upper connecting frame 203 are moved up synchronously. The side connecting buckle 202 is moved up close to the upper fixing plate 2. The protruding plane at the lower part of the side connecting buckle 202 fits with the lower side plane of the upper fixing plate 2 to pull the upper fixing plate 2 to move up synchronously. The upper fixing frame 102 pulls the upper fixing plate 2 through the side connecting buckle 202 to move up synchronously. After the upper fixing plate 2 is moved up to push the upper immersion nozzle higher than the outer guide frame 3, the immersion nozzle rolls to the side of the outer guide frame 3. The immersion water inlet is moved and exported along the outer inclined surface of the outer guide frame 3, eliminating the need for personnel to manually replace the immersion water inlet. Personnel only need to place the immersion water inlet, which speeds up the replacement of the immersion water inlet; when the immersion water inlet rolls, the upper end of the side connection buckle 202 contacts the upper inclined surface of the outer guide inclined frame 204, and the upper inclined surface of the outer guide inclined frame 204 guides the upper end of the side connection buckle 202 to rotate toward the side of the upper fixed plate 2, and the lower end of the side connection buckle 202 rotates toward the side away from the upper fixed plate 2, and the lower end of the side connection buckle 202 is separated from the upper fixed plate 2, and the raised upper fixed plate 2 moves down to reset;

[0036] The side reset tension spring 302 pulls the tail end of the middle resistance plate 301 to tilt up, and the middle resistance plate 301 slows down the submerged water outlet rolling on the upper part of the outer guide frame 3. The submerged water outlet slows down along the slope of the middle resistance plate 301, and at the same time, the submerged water outlet will also lower the height of the middle resistance plate 301. When the middle resistance plate 301 is flush with the outer guide frame 3, the submerged water outlet rotates through the middle resistance plate 301, and the middle resistance plate 301 can also support the submerged water outlet to stop in position. When there are two submerged water outlets, the thrust of the submerged water outlet on the middle resistance plate 301 increases to release one submerged water outlet, thereby realizing the pause and deceleration of the submerged water outlet in the middle part of the outer guide frame 3, reducing the speed of the submerged water outlet, and reducing the collision force between the submerged water outlets.
