Description

Technical Field

[0001] The invention relates to the technical field of finishing of a bar production line in the metallurgical industry, and in particular to a locking device of a mobile sizing machine. Background Art

[0002] The mobile cut-to-length machine consists of a cut-to-length trolley, a crossbeam, a bracket, a hydraulic system and other main parts. The cut-to-length trolley is equipped with a baffle lifted by a hydraulic cylinder, a motor drive device that moves on the crossbeam, and a hydraulic locking device on the crossbeam for positioning the steel plate shear size. The crossbeam is equipped with a locking structure that matches the longitudinal positioning of the cut-to-length trolley and a scale plate for indicating the cut-to-length length. The locking device for beam positioning uses a disc spring locking cylinder to support the side plane of the crossbeam rack. After the baffle is frequently hit by steel parts, it will produce a slight displacement, which will seriously affect the length of the finished rolled product after long-term production.

[0003] At present, the existing locking device of the cut-to-length trolley uses the shaft connection plane of the disc spring cylinder to abut against the adjustment rack on the cut-to-length trolley, and achieves locking through the friction between the planes.

[0026] Before describing the embodiments of the present invention in detail, the application environment of the present invention is described first. The technology of the present invention is mainly applied to the finishing technology field of bar production lines in the metallurgical industry. The present invention is used to solve the problem that the existing moving fixed-length machine frequently collides with the baffle during the steel plate production process, which easily causes the position of the fixed-length trolley to shift, resulting in a change in the positioning size and causing a deviation in the shearing size accuracy of the steel plate.

[0027] Please refer to Figures 1 to 3 As shown, the present invention provides a locking device for a moving fixed-length machine, including a fixed-length trolley 8, a cross beam 9, a bracket 10, a hydraulic system 11, a traveling drive component 12, and a traveling transmission component 13. The bracket 10 is used to support the cross beam 9. The fixed-length trolley 8 is slidably arranged on the cross beam 9. The traveling transmission component 13 is fixedly arranged on the cross beam 9. The hydraulic system 11 and the traveling drive component 12 are arranged on the fixed-length trolley 8. A baffle 14 for blocking the steel plate is connected to the hydraulic system 11. The traveling drive component 12 cooperates with the traveling transmission component 13 to drive the fixed-length trolley 8 to travel. The locking device of the moving fixed-length machine further includes:

[0028] In an exemplary embodiment of the present application, there is a mounting base 1 which is used to connect with the sizing trolley 8; a lifting and locking mechanism 2 is arranged on the mounting base 1. The lifting and locking mechanism 2 includes a lifting driving component 201 and a locking component 202. The locking component 202 is connected with the lifting driving component 201. The lifting driving component 201 is used to drive the locking component 202 to move along the height direction of the mounting base 1, so that the locking component 202 cooperates with the traveling transmission component 13 to lock the sizing; a limiting mechanism 3 includes at least two limiting components 301. The at least two limiting components 301 are symmetrically arranged at one end of the mounting base 1 along the height direction. The limiting component 301 is used to limit the length direction of the locking component 202.

[0029] In this embodiment, the cross beam 9 is arranged above the roller path 15 along the transmission direction of the roller path 15. The cross beam 9 is supported by a bracket 10. The sizing trolley 8 is slidably connected to the lower end of the cross beam 9. A hydraulic system 11 is arranged on the sizing trolley 8. The front end of the hydraulic system 11 is connected to a baffle 14 for blocking the steel plate. The hydraulic system 11 is used to drive the baffle 14 to move up and down and buffer the impact force when the baffle 14 is impacted by the steel plate. On one side of the lower end of the cross beam 9 facing the roller path 15, there is a traveling transmission component 13. The traveling transmission component 13 is a rack which is fixedly arranged at the lower end of the cross beam 9. A traveling driving component 12 is arranged on the sizing trolley 8 and is arranged on one side of the sizing trolley 8 along the width direction of the roller path 15. The traveling driving component 12 is a stepping motor. A gear is arranged on the output shaft of the stepping motor. The gear meshes with the tooth pattern of the rack on the lower end of the cross beam 9. By driving the gear to rotate through the motor, the sizing trolley is driven to move back and forth along the transmission direction of the roller path 15. There is also a locking structure on the top of the sizing trolley 8. The locking structure is a hydraulic cylinder. When the sizing trolley 8 finishes traveling and sizing, the shaft of the locking structure hydraulic cylinder extends out and abuts against the rack, and the sizing trolley 8 is locked with the rack of the traveling transmission component 13 through friction; in the present application, by adding a locking device to the existing moving sizing machine, the locking device is fixedly connected with the sizing trolley 8 through the mounting base 1. The lifting driving component 201 of the lifting and locking mechanism 2 drives the locking component 202 to be able to move along the height direction of the mounting base 1. When the sizing trolley 8 needs to travel to adjust the cutting size of the steel plate, the lifting driving component 201 drives the locking component 202 to move down. When the sizing is completed, the lifting driving component 201 drives the locking component 202 to move up to cooperate with the traveling transmission component 13 on the cross beam 9 to lock the sizing. Through the limiting mechanism 3 arranged on the mounting base 1, the length direction of the locking component 202 can be limited. When the steel plate frequently impacts the baffle 14, the limiting component 301 has the effect of improving the impact resistance of the locking component 202, thereby reducing the risk of displacement of the locking component 202 after the steel plate frequently impacts the baffle 14, and further having the beneficial effect of improving the product qualification rate.

[0030] In an exemplary embodiment of the present application, the mounting base 1 includes a first bottom plate 101, a second bottom plate 102, and a mounting plate 103. The mounting plate 103 is perpendicular to the second bottom plate 102 and is used for mounting the lifting drive component 201. The second bottom plate 102 is parallel to the first bottom plate 101, and the second bottom plate 102 and the first bottom plate 101 are locked and connected by a locking member. The first bottom plate 101 is welded to the sizing trolley 8.

[0031] In this embodiment, the mounting plate 103 is horizontally arranged, the second bottom plate 102 is vertically arranged, and the mounting plate 103 is perpendicular to the second bottom plate 102. The first bottom plate 101 is fixedly welded to the rear end of the sizing trolley 8. The second bottom plate 102 is locked and fixed to the first bottom plate 101 by six locking members. The locking members adopt bolt-nut assemblies. The first bottom plate 101 and the second bottom plate 102 are parallel to each other, that is, the first bottom plate 101 is vertically welded and fixed on the side surface of the rear end of the sizing trolley.

[0032] In an exemplary embodiment of the present application, the lifting drive component 201 is a disc spring oil cylinder. The mounting plate 103 is provided with a mounting groove 103a for mounting the lifting drive component 201 along the thickness direction. The mounting groove 103a is provided with a limiting boss 103b for limiting and mounting the lifting drive component 201. The lifting drive component 201 and the limiting boss 103b are locked and connected by a locking member.

[0033] In this embodiment, the lifting drive component 201 shown in the embodiment of the present application adopts a disc spring oil cylinder, which eliminates the influence of hydraulic cylinder leakage on the locking force. The mounting plate 103 is provided with a mounting groove 103a for mounting the lifting drive component 201 along the thickness direction. The bottom of the mounting groove 103a is provided with a limiting boss 103b extending towards the center line of the mounting groove 103a. The upper end of the lifting drive component 201 is provided with a clamping table 201d extending radially along the telescopic rod 201a of the lifting drive component 201 for abutting and cooperating with the limiting boss 103b. The limiting boss 103b and the clamping table 201d are provided with mounting holes for passing through the locking member along the thickness direction. The locking member adopts a bolt-nut assembly. The bolt passes through the mounting holes of the limiting boss 103b and the clamping table 201d to lock and fix the lifting drive component 201 on the mounting plate 103. The cooperation between the limiting boss 103b and the clamping table 201d can provide sufficient bearing capacity for the lifting drive component 201.

[0034] In an exemplary embodiment of the present application, the limiting mechanism 3 includes two limiting components 301. The two limiting components 301 are symmetrically arranged on the mounting plate 103. The limiting plate is provided with a guiding groove 301a for guiding the movement of the locking component 202. The two ends of the locking component 202 in the length direction are respectively slidably connected to the two guiding grooves 301a.

[0035] In this embodiment, two limiting components 301 are symmetrically arranged at both ends of the mounting plate 103 along the length direction. The limiting component 301 is provided with a guiding groove 301a along the vertical direction. The openings of the guiding grooves 301a on the two limiting components 301 are both arranged towards the center line of the limiting groove 201b. Both ends of the locking component 202 along the length direction are respectively slidably connected to the guiding grooves 301a on the two limiting components 301. The connecting surface between the locking component 202 and the guiding groove 301a adopts a clearance fit. When the sizing trolley 8 needs to move, the lifting driving component 201 drives the locking component 202 to rise or fall along the guiding groove 301a of the limiting component 301. When the baffle 14 is impacted by the steel plate, the impact force at the front end is transmitted to the locking component 202. The locking component 202 is of a rack structure. The locking component 202 meshes with the rack teeth of the traveling transmission component 13, so as to resist the impact force generated when the steel plate impacts the baffle 14, thereby preventing the sizing trolley 8 from displacing and causing deviation in sizing and shearing accuracy. When the locking component 202 is stressed, the telescopic rod 201a of the lifting driving component 201 is subjected to a radial force. Through the matching relationship between the guiding groove 301a on the limiting component 301 and the locking component 202, the radial force received by the telescopic rod 201a of the lifting driving component 201 can be effectively resisted, thereby preventing the telescopic rod 201a of the lifting driving component 201 from having a radial displacement, and further ensuring that the sizing trolley 8 will not displace when impacted by the steel plate, so as to avoid the problem of deviation in shearing size accuracy.

[0036] In an exemplary embodiment of the present application, a limiting groove 201b is provided along the radial direction of the telescopic rod 201a of the lifting driving component 201. A connecting pressure block 201c is sleeved on the limiting groove 201b. The connecting pressure block 201c and the locking component 202 are tightly connected through a locking member.

[0037] In an exemplary embodiment of the present application, an anti-slip pad 202a is provided on one side of the mounting plate 103 along the thickness direction close to the lifting driving component 201. The anti-slip pad 202a is used to abut against one end of the telescopic rod 201a of the lifting driving component 201 along the axial direction.

[0038] In this embodiment, by providing the anti-slip pad 202a on one side of the mounting plate 103 along the thickness direction close to the lifting driving component 201, when the impact force at the front end is transmitted to the locking component 202, since the locking component 202 and the guiding groove 301a of the limiting component 301 have a clearance fit, the locking component 202 will have a slight movement. By providing the anti-slip pad 202a at the bottom of the locking component 202 to abut against the telescopic rod 201a of the lifting driving component 201, the friction between the lifting driving component 201 and the locking component 202 can be increased, thereby further reducing the risk of the locking component 202 shifting in position. At the same time, it has the beneficial effect of preventing damage to the surfaces of the telescopic rod 201a of the lifting driving component 201 and the locking component 202.

[0039] In an exemplary embodiment of the present application, a partition portion 104 is provided between the opposite two side surfaces of the first bottom plate 101 and the second bottom plate 102, and the partition portion 104 is used to divide the connection area between the first bottom plate 101 and the second bottom plate 102 into a first area and a second area.

[0040] In this embodiment, a connection area is formed between the opposite two surfaces of the first bottom plate 101 and the second bottom plate 102. In the connection area, the connection area is divided into a first area and a second area by the partition portion 104, and the locking member passes through the connection area to connect the second bottom plate 102 and the first bottom plate 101.

[0041] In an exemplary embodiment of the present application, a first gasket 4 is provided on the first area, a second gasket 5 is provided on the second area, and the first gasket 4 and the second gasket 5 have the same thickness.

[0042] In an exemplary embodiment of the present application, a first inclined backing plate 6 is provided between the first gasket 4 and the second bottom plate 102 in the first area, and a second inclined backing plate 7 is provided between the first gasket 4 and the second bottom plate 102 in the second area.

[0043] In an exemplary embodiment of the present application, both the first inclined backing plate 6 and the second inclined backing plate 7 are wedge-shaped structures, and the inclination angle of the first inclined backing plate 6 is the same as the inclination angle of the second inclined backing plate 7.

[0044] The first gasket 4 and the second gasket 5 can be knocked into the first area and the second area from both ends of the side surface of the connection area at the connection area between the first bottom plate 101 and the second bottom plate 102 to adjust the fixed scale length. The first gasket 4 and the second gasket 5 can be selected according to requirements, and the thickness adjustment range is between 0 mm and 50 mm. In combination with the first inclined backing plate 6 and the second inclined backing plate 7, the first inclined backing plate 6 is knocked into the space between the second bottom plate 102 and the first gasket 4 in the first area, and the second inclined backing plate 7 is knocked into the space between the second bottom plate 102 and the second gasket 5 in the second area to adjust the fixed scale length in a small range. The adjustment range of the first inclined backing plate 6 and the second inclined backing plate 7 is between 0 mm and 5 mm. Since the first backing plate and the second backing plate adopt wedge-shaped structures, the first inclined backing plate 6 and the second inclined backing plate 7 can be knocked into the first area and the second area to the required depth to adjust the fixed scale length. By the combined use of the first gasket 4, the second gasket 5, the first inclined backing plate 6 and the second inclined backing plate 7, the beneficial effect of being able to adjust any fixed scale length of the moving fixed scale machine can be achieved.

[0045] Working principle: The crossbeam 9 is arranged above the roller path 15 along the driving direction of the roller path 15. The crossbeam 9 is supported by the bracket 10. The sizing trolley 8 is slidably connected to the lower end of the crossbeam 9. The hydraulic system 11 is arranged on the sizing trolley 8. The front end of the hydraulic system 11 is connected to the baffle 14 for blocking the steel plate. The hydraulic system 11 is used to drive the baffle 14 to move up and down and buffer the impact force when the baffle 14 is impacted by the steel plate. On the side of the lower end of the crossbeam 9 facing the roller path 15, there is a traveling drive component 13. The traveling drive component 13 is a rack, and the rack is fixedly arranged at the lower end of the crossbeam 9. The traveling drive component 12 is arranged on the sizing trolley 8 and is arranged on one side of the sizing trolley 8 along the width direction of the roller path 15. The traveling drive component 12 is a stepping motor. A gear is arranged on the output shaft of the stepping motor, and the gear meshes with the tooth pattern of the rack on the lower end of the crossbeam 9. By driving the gear to rotate through the motor, the sizing trolley is driven to move back and forth along the driving direction of the roller path 15. A locking structure is also arranged on the top of the sizing trolley 8. The locking structure is a hydraulic cylinder. When the sizing of the sizing trolley 8 is completed, the shaft of the locking structure hydraulic cylinder extends out and abuts against the rack, and the sizing trolley 8 is locked with the rack of the traveling drive component 13 by friction;In this application, a locking device is added to the existing moving fixed-length machine. The locking device is fixedly connected to the fixed-length trolley 8 through the mounting seat 1. The lifting drive component 201 of the lifting and locking mechanism 2 drives the locking component 202 to move along the height direction of the mounting seat 1. When the fixed-length trolley 8 needs to move to adjust the cutting size of the steel plate, the lifting drive component 201 drives the locking component 202 to move downward. When the fixed length is completed, the lifting drive component 201 drives the locking component 202 to move upward to cooperate with the traveling transmission component 13 on the cross beam 9 to lock the fixed length. Through the limiting mechanism 3 provided on the mounting seat 1, the length direction of the locking component 202 can be limited. When the steel plate frequently impacts the baffle 14, the limiting component 301 has the effect of improving the impact resistance of the locking component 202, thereby reducing the risk of displacement of the locking component 202 after the steel plate frequently impacts the baffle 14, which may cause deviation in the finished product precision of the rolled piece, and thus has the beneficial effect of improving the yield rate of the product. Moreover, the first gasket 4 and the second gasket 5 can be knocked into the first area and the second area from the side ends of the connection area at the connection area between the first bottom plate 101 and the second bottom plate 102 to adjust the fixed length. The first gasket 4 and the second gasket 5 can be selected according to requirements, and the thickness adjustment range is between 0 mm and 50 mm. In combination with the first inclined gasket 6 and the second inclined gasket 7, the first inclined gasket 6 is knocked into the space between the second bottom plate 102 and the first gasket 4 in the first area, and the second inclined gasket 7 is knocked into the space between the second bottom plate 102 and the second gasket 5 in the second area to finely adjust the fixed length. The adjustment range of the first inclined gasket 6 and the second inclined gasket 7 is between 0 mm and 5 mm. Since the first gasket and the second gasket adopt a wedge-shaped structure, the first inclined gasket 6 and the second inclined gasket 7 can be knocked into the first area and the second area to the required depth to adjust the fixed length. Through the combined use of the first gasket 4, the second gasket 5, the first inclined gasket 6 and the second inclined gasket 7, the beneficial effect of enabling the moving fixed-length machine to adjust any fixed length can be achieved.;

[0046] The above embodiments merely illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
