Description

Technical Field

[0001] The utility model relates to the technical field of metal hot processing tooling, in particular to a digital displacement measurement system for a roller company operating machine. Background Art

[0002] As the main equipment in the forging process, the manipulator's smooth and efficient operation directly affects the quality and cost of the product. The current production model is that after the on-site personnel use measuring tools to measure the length of the workpiece, the manipulator driver controls the forward and backward distance of the equipment according to the workpiece's process requirements and cooperates with the press to carry out production. This process has the following defects:

[0003] 1. The accuracy of manual measurement is low, and large dimensional deviations affect product quality.

[0004] 2. Manual measurement speed is slow. In order to ensure the normal forging process, the workpiece temperature out of the furnace needs to be increased to reduce the effect of heat dissipation in the air;

[0005] 3. The surface temperature of the workpiece is about 1200℃. The distance during manual measurement is relatively close, the operating environment is harsh and there are safety hazards.

[0006] Therefore, it is very necessary to improve the existing tooling and solve the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a digital displacement measurement system for a roller company operating machine, so as to effectively solve the problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a digital displacement measurement system for a rolling mill company's manipulator, comprising a manipulator, a laser rangefinder, and a control system; the manipulator is a box-shaped structure, driven by a driver on a track of a fixed length, a clamp for clamping a workpiece is fixed on the outer side of the front end of the box, a reflector is fixed on the front side of the box, a laser rangefinder is provided at the end of the track, the front end of the track is the upper and lower shims of the forging machine, and the upper end of the upper shim is fixed to the column of the lower hydraulic cylinder; the control system is arranged in the manipulator and controlled by the driver, and the laser rangefinder 1 is connected to the control system via a cable.

[0009] Preferably, the laser beam emitted by the laser rangefinder will encounter the reflector and then reflect to the laser rangefinder. The laser rangefinder calculates the distance between the reflector and the laser rangefinder. Since the track length is a fixed value, the control system can convert the distance between the reflector and the lower pad of the forging machine and display it on the screen. The process setting distance between the operating machine and the lower pad of the forging machine is input into the control system in advance. The driver controls the operating machine to move back and forth. When the display screen of the control system shows that the operating machine is in the process setting position, the driver stops moving the operating machine, and the operating machine is in the correct position.

[0010] During production, a double-girder bridge crane is used in conjunction with a lifting chain to lift the forging to the front side of the manipulator. The driver uses the jaws of the manipulator to clamp one end of the forging, lifts it horizontally and adjusts the position, and then places the other end of the forging on the pad under the press. The driver operates the clamp to adjust the workpiece to a horizontal level and moves the manipulator back and forth. When the display shows that the manipulator is in the position required by the process, the driver pulls the handle to the empty position. After the manipulator stops, the hammer head of the forging press presses down to start forging.

[0011] Beneficial effects of the utility model:

[0012] 1. Using laser ranging to improve the measurement accuracy of workpieces from ±5mm to ±1mm, greatly improving the production quality of the forging process.

[0013] 2. Digital automatic and rapid measurement reduces the waiting time of workpieces in the air, reduces heat dissipation and saves costs.

[0014] 3. The original mode required the cooperation of on-site personnel and the operator. After the improvement, only the operator needs to work independently, which reduces the time for on-site personnel to approach high-temperature workpieces, improves the working environment, reduces safety risks, and further improves production efficiency.

[0017] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Attachment Figure 1As shown, a digital displacement measurement system for a rolling mill company's manipulator includes a manipulator, a laser rangefinder, and a control system. The manipulator 3 is a box-shaped structure and is driven by a driver on a track 10 of fixed length. A clamp 9 for clamping a workpiece 5 is fixed to the outside of the front end of the box, a reflector 4 is fixed to the front side of the box, a laser rangefinder 1 is provided at the end of the track, and the front end of the track is the upper shim 7 and lower shim 8 of the forging machine, and the upper end of the upper shim 7 is fixed to the column of the lower hydraulic cylinder 6. The control system is arranged in the manipulator and controlled by the driver, and the laser rangefinder 1 is connected to the control system via a cable.

[0019] The laser beam 2 emitted by the laser rangefinder 1 will encounter the reflector 4 and then reflect to the laser rangefinder. The laser rangefinder calculates the distance between the reflector and the laser rangefinder. Since the track length is a fixed value, the control system converts the distance between the reflector 4 and the lower pad 8 of the forging machine and displays it on the screen. The process setting distance between the operating machine and the lower pad 8 of the forging machine is input into the control system in advance. The driver controls the operating machine to move back and forth. When the display screen of the control system shows that the operating machine is in the process setting position, the driver stops moving the operating machine, and the operating machine is in the correct position.

[0020] During production, a double-beam bridge crane is used in conjunction with a lifting chain to lift the forging to the front side of the manipulator. The driver operates the jaws of the manipulator to clamp one end of the forging, lifts it horizontally and adjusts the position, and then places the other end of the forging on the pad 8 under the press. The driver operates the clamp to adjust the workpiece to a horizontal level and moves the manipulator back and forth. When the display shows that the manipulator is in the position required by the process, the driver pulls the handle to the empty position. After the manipulator stops, the hammer head of the forging press presses down to start forging.

[0021] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
