Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic shearing machines, in particular to a fixed-length shearing type hydraulic shearing machine. Background Art

[0002] Hydraulic shearing machine is a common metal processing equipment, mainly used for shearing metal plates. Its main devices include hydraulic system, shearing mechanism, transmission system and control system. One of the core components of hydraulic shearing machine is to transmit force through the pressure of hydraulic oil to drive the shearing knife to perform shearing operation. The hydraulic system usually includes hydraulic pump, oil tank, hydraulic valve and other components, which can provide sufficient power and pressure. Hydraulic shearing machine is used for cutting, trimming and other processing procedures of metal plates, and is widely used in the processing and manufacturing fields of metal materials such as steel, aluminum alloy and stainless steel.

[0003] When a hydraulic shearing machine is needed to cut a plate to a fixed length, when the existing hydraulic shearing machine cuts a plate to a fixed length, the staff uses a measuring tool to measure and determine the cutting length of the plate. The staff relies on manually using the measuring tool to measure and adjust, which is easily affected by human errors, resulting in inaccurate cutting length and affecting the processing quality. Manual measurement and adjustment require additional time and human resources, especially in the case of mass production, which will increase the production cycle and cost. Frequent measurement and adjustment require a high labor intensity for the staff, which can easily cause fatigue and low work efficiency. Manual adjustment is easily affected by external environmental factors, such as the operator's technical level, working status, etc., resulting in insufficient stability in the cutting length.

[0023] Embodiment 2

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The utility model discloses a fixed-length shearing type hydraulic shearing machine, comprising a hydraulic shearing machine device 1 and a shearing platform 20 installed on the inner surface of the hydraulic shearing machine device 1, a fixed-distance pushing component is installed on the outer surface of the shearing platform 20, a push plate 8 is installed inside the fixed-distance pushing component, a detection component is installed inside the push plate 8, the fixed-distance pushing component comprises a stepping motor 5 and a ball screw 6, the stepping motor 5 is installed on the inner surface of the shearing platform 20, the ball screw 6 is installed on the outer surface of the output end of the stepping motor 5, a screw slider 7 is movably installed on the outer surface of the ball screw 6, a limiting column 9 is installed on the inner surface of the shearing platform 20, one end surface of the screw slider 7 is fixedly connected to one end surface of the push plate 8, the inside of the push plate 8 is connected to the limiting column 9 The outer surface is in active contact, and the detection component includes a detection cavity 10 and a protection spring 11.

The controller controls the stepper motor 5 to work, and the stepper motor 5 drives the ball screw 6 to rotate. The ball screw 6 cooperates with the screw slider 7 to make the screw slider 7 drive the push plate 8 to move. Under the action of the limit column 9, the push plate 8 stably drives the pressure detector 12 to move in the direction of the plate. When the pressure detector 12 contacts the plate, the pressure detector 12 presses the protective spring 11. Extrusion, and the protection spring 11 has elastic deformation, so that the pressure detector 12 squeezes the surface of the plate. When the pressure detector 12 detects a certain value, the pressure detector 12 detects and transmits the signal to the controller. The controller controls the stepper motor 5 to stop working.

[0026] When it is necessary to cut the plate of a certain length, the controller controls the output power and working time of the stepper motor 5 to ensure the moving distance of the screw slider 7 and the push plate 8, and the end faces of the baffle fixing block 15 and the limit plate 19 are at the same horizontal plane with the wall surface of the cutting groove 4, so as to determine the moving distance of the plate. By accurately controlling the output power and working time of the stepper motor 5, it is ensured that the moving distance of the push plate 8 accurately reaches the required length, and the plate is accurately cut. The controller can automatically monitor and adjust the working state of the stepper motor 5 without manual intervention, making the operation more convenient and improving the production efficiency. During the cutting process, the moving distance of the plate can be kept consistent, ensuring the consistency and quality stability of the cutting results. The push plate 8 pushes the plate to move in the opposite direction of the extension cavity 2, and the plate also pushes the limit plate 19. The limit plate 19 drives the limit column 9 to rotate in the baffle fixing block 15. The limit plate 19 will simultaneously pull the elastic rope 14 to make the limit plate 19 return to its original position.
