Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinet plate processing, and more specifically, it relates to a novel stretching mechanism for distribution cabinet plate processing. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in occasions where the load is concentrated and there are more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. At the same time, the shell of the distribution cabinet is made of sheet metal, and the existing technology needs to cut, stretch, bend, weld, grind and polish the sheet metal before processing the sheet metal of the distribution cabinet, so that the sheet metal processed through various operations can be assembled into the whole of the distribution cabinet.

[0003] However, the existing plates are curled and need to be straightened. A plate stretching machine is usually used for stretching and straightening. Specifically, the two ends of the plate are respectively connected to the front chuck and the rear chuck of the stretching machine, and then one of the chucks is controlled by the cylinder to stretch the plate. After stretching, the plate will be in a flat state.

[0004] However, the plate stretching machine in the prior art only has a front clamp and a rear clamp to achieve the stretching of the plate. If the bending force of the plate is large during the stretching process, the plate will still be uneven after stretching, which will affect the efficiency and quality of the plate stretching. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a new type of stretching mechanism for processing distribution cabinet plates, which can press and stretch the plates simultaneously under the action of the plate pressing component and the plate stretching component, thereby preventing the plates from generating large bending forces during the stretching process and affecting the stretching effect of the plates.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a new type of stretching mechanism for plate processing in a distribution cabinet, comprising a plate processing frame, on which a plate placing frame and a plate stretching assembly are arranged, and a plate pressing assembly is arranged at the upper end of the plate processing frame, and the plate pressing assembly comprises a first pressing assembly and a second pressing assembly, and the first pressing assembly and the second pressing assembly are respectively arranged at the two ends of the plate placing frame, and the plate stretching assembly comprises a clamping plate arranged at both ends of the plate placing frame, a sliding base fixedly connected to the bottom of the clamping plate, a bidirectional screw rod inserted in the sliding base, and a stepping motor for driving the bidirectional screw rod to rotate, and a first threaded hole for inserting the bidirectional screw rod is opened inside the sliding base.

[0007] By adopting the above technical scheme, the staff first places the plate on the plate placing rack, so that the two ends of the plate are first clamped by the clamping plates of the plate stretching assembly to fix the plate, and then the plate is pressed by the first pressing assembly and the second pressing assembly in turn, and then the pressing effect of the first pressing assembly and the second pressing assembly is turned off, so that the staff starts the motor again, so that the motor drives the bidirectional screw rod to rotate, and the bidirectional screw rod rotates in the sliding base at the bottom of the clamping plate, and the first threaded hole opened by the bidirectional screw rod and the sliding base continues to rotate, then the sliding bases at both ends will gradually move away, and the plate clamped by the clamping plate can be stretched as the clamping plate moves, and the second pressing assembly is started to press the plate at the same time, so that the plate is restricted on all sides during the stretching process to prevent the plate from having a large bending force and causing an uneven surface, thereby ensuring the effect of plate stretching, and the quality of the output plate will also be guaranteed. At the same time, the surface of the distribution cabinet installed with the manufactured plate will also be flat.

[0008] The utility model is further configured as follows: the first pressing assembly includes a first pressing roller, a motor for driving the first pressing roller to rotate, a driving assembly for driving the first pressing roller to approach the plate, and a moving assembly for driving the first pressing roller to reciprocate on the plate.

[0009] By adopting the above technical solution, the motor is first started to drive the first pressing roller to rotate, and then the driving component is used to move the rotating first pressing roller close to the plate. Finally, the staff uses the moving component to realize the reciprocating movement and pressing effect of the first pressing roller on the surface of the plate, thereby improving the pressing efficiency of the first pressing roller and preventing the plate from becoming uneven due to large bending force during the stretching process, thereby ensuring the quality and effect of the plate after stretching.

[0010] The utility model is further configured as follows: the driving assembly comprises a first cylinder arranged between the motor and the plate processing frame.

[0011] By adopting the above technical solution, the first cylinder is started to drive the motor and the first pressing roller to move toward the direction in which the plate is set, and the action accuracy of the first cylinder is high, which will not cause the first pressing roller to crush the plate, thereby ensuring the pressing effect of the first pressing roller and preventing large indentations on the surface of the plate.

[0012] The utility model is further configured as follows: the moving assembly comprises a sliding block and a sliding rod arranged on a plate processing frame, and a through hole for the sliding rod to pass through is opened inside the sliding block.

[0013] By adopting the above technical solution, when the first pressing roller contacts the surface of the plate, the staff can drive the first pressing roller to slide along the surface of the plate by pushing the sliding block to move along the surface of the sliding rod, thereby pressing the entire stretched plate to prevent the plate from becoming uneven due to large bending force during the stretching process, thereby ensuring the efficiency and effect of plate stretching.

[0014] The utility model is further configured as follows: the second pressing assembly includes a plurality of second pressing rollers arranged just above the plate placing rack, the plurality of second pressing rollers are distributed in an equidistant array, and a second cylinder is arranged on the second pressing roller.

[0015] By adopting the above technical solution, the staff can start the second cylinder to drive the second pressing rod to move toward the plate. At the same time, the staff can intermittently drive the second pressing rod to press the plate, and can also drive all the second pressing rods close to the plate at the same time, thereby achieving a pressing effect on the plate and preventing the plate from becoming uneven due to large bending force during the stretching process.

[0016] The utility model is further configured as follows: the clamping plate includes a fixed plate and a movable plate, the fixed plate is configured in a concave shape, the movable plate is slidably connected to the fixed plate, a threaded rod is rotatably connected to the movable plate, and a second threaded hole for the threaded rod to rotate is opened on the fixed plate.

[0017] By adopting the above technical solution, when the plate needs to be fixed, the staff first needs to rotate the threaded rod gradually away from the movable plate, and wait for the plate to be placed in the gap between the movable plate and the fixed plate. Then, the staff rotates the threaded rod again, so that the threaded rod rotates in the second threaded hole and pushes the movable plate toward the direction close to the plate. After the movable plate fits the surface of the plate, the threaded rod is tightened to make the movable plate in close contact with the plate to achieve the clamping effect of the plate. The simple structure is easy for the staff to understand and operate, thereby reducing the staff's work intensity to improve the efficiency of plate processing, thereby improving the processing efficiency of the entire distribution cabinet.

[0018] The utility model is further configured as follows: one end of the movable plate away from the threaded rod is protrudingly provided with a plurality of anti-slip protrusions distributed in an array.

[0019] By adopting the above technical solution, several anti-slip protrusions distributed in an array will contact the stretched plate, thereby increasing the friction between the movable plate and the plate, ensuring the stability of the plate clamped in the clamping plate, and at the same time maintaining the stability and friction of the plate during the stretching process, thereby improving the effect and efficiency of the distribution cabinet plate stretching.

[0020] The utility model is further configured as follows: the plate placing rack comprises a supporting frame and a plurality of rotating rollers rotatably connected to the supporting frame.

[0021] By adopting the above technical solution, a plurality of rotating rollers can be rotated on the support frame during the stretching process of the plate, which can further improve the efficiency of the plate stretching, and further improve the production efficiency of the distribution cabinet door plate.

[0022] In summary, the utility model has the following beneficial effects: under the action of the plate pressing component and the plate stretching component, the plate can be pressed and stretched at the same time, preventing the plate from generating a large bending force during the stretching process and affecting the effect of the plate stretching, thereby improving the efficiency and effect of the plate stretching.
