Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting, and more specifically to a steel bar cutting device for PCCP pipe production. Background Art

[0002] PCCP pipe is a prestressed steel tube concrete pipe, which is a water pipe made of steel bars and high-strength concrete as the skeleton, and a dense cement mortar protective layer is sprayed thereon. When producing PCCP pipes of different specifications, it is necessary to cut steel bars of different lengths. In the use of the existing device for cutting steel bars, the staff usually manually presses the steel bars to fix the steel bars on the cutting device. However, this pressing and fixing method is not stable, and it is easy to cause deviation and rolling under the force of the cutting knife, which reduces the cutting accuracy of the steel bars. Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a steel bar cutting device for PCCP pipe production is provided, in order to achieve a more practical purpose. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a steel bar cutting device for PCCP pipe production to solve the problems existing in the above-mentioned background technology.

[0004] The utility model provides the following technical solutions: a steel bar cutting device for PCCP pipe production, comprising a placing table, a steel bar rod, and a lifting and cutting assembly, a gantry is fixedly installed on the upper end of the placing table, a threaded rod is movably penetrated and installed on the upper end surface of the gantry through a thread, a rotating block is fixedly installed on the upper end of the threaded rod, a limiting turntable is fixedly installed on the bottom end of the threaded rod, a pressure plate is movably installed on the outer side of the limiting turntable, sliders are fixedly installed on both ends of the pressure plate, two sliding grooves corresponding to the sliders are opened on the inner side of the gantry, and an arc-shaped groove is arranged on the bottom end surface of the pressure plate.

[0005] Furthermore, a number of balls are evenly embedded in the outer side of the limit turntable, and the balls movably contact the inner wall of the pressure plate. Through the active contact between the balls and the inner wall of the pressure plate, the limit turntable can rotate more smoothly in the pressure plate.

[0006] Furthermore, guide rods are fixedly installed in the gantry slide grooves, and the guide rods slide through the sliders. The sliders are guided by the guide rods, thereby enhancing the smooth movement of the sliders.

[0007] Furthermore, a buffer pad is fixedly installed in the arc-shaped groove at the bottom end of the pressure plate, and the surface of the buffer pad is provided with anti-slip grooves. When the pressure plate presses against the steel bar, the buffer pad cushions the material where the pressure plate presses against the material to prevent the pressure plate from excessively pressing the steel bar and causing damage to the pressure plate. At the same time, the protective grooves on the surface of the pressure plate can strengthen the friction between the pressure plate and the steel bar, thereby improving the stability of the fixation of the steel bar.

[0008] Furthermore, a placement groove corresponding to the steel bar is opened on the upper end surface of the placement table, and the placement groove is used to guide the placement position of the steel bar on the upper end surface of the placement table, thereby reducing the possibility of the steel bar rolling after being placed on the device, thereby improving the accuracy of cutting the steel bar.

[0009] Furthermore, a cutting groove corresponding to the cutting knife of the lifting and cutting assembly is opened on the upper end surface of the placement table, and the depth of the cutting groove is greater than the depth of the placement groove. When the cutting knife of the lifting and cutting assembly finishes cutting the material, the cutting knife of the steel bar rod can easily touch the end surface of the placement table, thereby causing damage to the end surface of the placement table. The end surface of the placement table is protected by the cutting groove corresponding to the cutting knife of the lifting and cutting assembly.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model is provided with a gantry, a threaded rod, a rotating block, a limit turntable, a pressure plate and a sliding block. When in use, the threaded rod moves on the device to push the pressure plate, so that the steel bar is firmly fixed on the device, thereby avoiding the lifting and cutting assembly from shaking the steel bar when cutting the steel bar, which affects the cutting accuracy of the steel bar, thereby greatly improving the practicability of the device.

[0012] 2. The utility model is provided with a cutting groove. When the cutting knife of the lifting and cutting assembly finishes cutting the material, the cutting knife of the steel bar can easily touch the end surface of the placing table, thereby causing damage to the end surface of the placing table. The end surface of the placing table is protected by the cutting groove corresponding to the cutting knife of the lifting and cutting assembly, thereby greatly improving the practicality of the device.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Example 1: Please refer to Figure 1-4 The utility model provides a steel bar cutting device for PCCP pipe production, comprising a placing table 100, a steel bar rod 101, and a lifting and cutting assembly 102. A gantry 110 is fixedly installed on the upper end of the placing table 100, and a threaded rod 111 is movably installed through the upper end surface of the gantry 110 through a thread. A rotating block 112 is fixedly installed on the upper end of the threaded rod 111, and a limited turntable 113 is fixedly installed on the bottom end of the threaded rod 111. A pressure plate 114 is movably installed on the outer side of the limited turntable 113, and sliders 115 are fixedly installed at both ends of the pressure plate 114. Two sliding grooves corresponding to the sliders 115 are opened on the inner side of the gantry 110, and an arc groove is arranged on the bottom end surface of the pressure plate 114.

[0020] Working principle: When in use, the steel bar 101 is placed on the inner side of the gantry 110, and the threaded rod 111 is driven to move on the gantry 110 by rotating the turn block 112. The threaded rod 111 and the pressure plate 114 are connected by the limit turntable 113, so that when the threaded rod 111 moves on the gantry 110, it can move under the push of the threaded rod 111, and the movement of the pressure plate 114 is guided by the sliding of the slider 115 in the inner slide groove of the gantry 110 until the bottom end surface of the pressure plate 114 hits the fixed steel bar 101 and stops, and then the control button on the side of the device is used to control the lifting and cutting assembly 102 to descend and cut the steel bar 101.

[0021] Embodiment 2:

[0022] The difference between the second embodiment and the first embodiment is that: a number of balls 122 are evenly embedded in the outer side of the limit turntable 113, and the balls 122 are movable against the inner wall of the pressure plate 114. A guide rod 116 is fixedly installed in the slide groove of the gantry 110, and the guide rod 116 slides through the slider 115. A buffer pad 123 is fixedly installed in the arc groove at the bottom end of the pressure plate 114, and the surface of the buffer pad 123 is provided with anti-slip grooves. The upper end surface of the placement table 100 is provided with a placement groove 120 corresponding to the steel bar 101. A cutting groove 121 corresponding to the cutting knife of the lifting and cutting assembly 102 is provided on the upper end surface of the placement table 100. The depth of the cutting groove 121 is greater than the depth of the placement groove 120. When in use, the movement of the slider 115 is guided by the guide rod 116, and the placement position of the steel bar 101 is guided by the placement groove 120. When the lifting and cutting assembly 102 cuts off the steel bar 101, the cutting knife of the steel bar 101 will fall into the cutting groove 121, thereby protecting the surface of the placement table 100.

[0023] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
