Detailed Description
The present invention will be further described with reference to the following examples, which are only some, but not all, of the examples of the present invention. Based on the embodiments in the present invention, other embodiments used by those skilled in the art without creative work belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1, the device for assisting in quenching the leaf spring comprises a hydraulic push rod machine 1, a conveyor belt 2 and a clamping device 3, wherein the conveyor belt 2 is arranged between the hydraulic push rod machine 1 and the clamping device 3, the hydraulic push rod machine 1 and the clamping device 3 are oppositely arranged, and the hydraulic push rod machine 1 is used for pushing the leaf spring on the conveyor belt 2 to the clamping device 3.
The utility model discloses a set up hydraulic rod machine 1 and be used for with the not steel sheet propelling movement who quenches on conveyer belt 2 to centre gripping equipment 3 just opposite at centre gripping equipment 3, this kind of structure is fit for the at the uniform velocity equidistance of steel sheet and puts in conveyer belt 2 on, and the length of each work piece steel sheet is isometric, like this through the motor that sets up conveyer belt 2 for conveyer belt 2 satisfies the intermittent type operation and can satisfy, even when having the conveying to pause, the steel sheet just in the middle of the centre of conveyer belt 2 and centre gripping equipment 3. It should be noted here that the clamping device 3 of the present embodiment is a quenching machine, which facilitates the hydraulic push rod machine 1 to accurately push the steel plate onto the clamping device 3, so as to ensure that the clamping device 3 performs a subsequent quenching process. The labor intensity of workers in the process of machine quenching of the steel plate spring is reduced, and meanwhile, the risk of injury of the workers is reduced.
Example 2:
as shown in fig. 2, the present embodiment is further optimized based on embodiment 1, and the present embodiment focuses on explaining the improvement compared to embodiment 1, and the same points are not repeated, and in the present embodiment, the hydraulic push rod machine 1 includes a plurality of hydraulic push rods 4 moving independently from each other. The three hydraulic push rods 4 which move independently are arranged at equal intervals in the embodiment, and the hydraulic push rods 4 are arranged independently, because the steel plate is not parallel to the clamping surfaces of the conveyor belt 2 and the clamping device 3 under most conditions when a worker in front places the steel plate on the conveyor belt 2, and if the three synchronous hydraulic push rods 4 are used, the steel plate which pushes up the clamping device 3 is possibly not parallel to the clamping end of the clamping device 3.
Because the clamping device 3 has the function of bending the steel plate to form the steel plate spring, when the situation occurs, the steel plate cannot be formed into the bending shape and the bending angle which meet the design and use requirements of the steel plate spring.
Example 3:
as shown in fig. 2, the present embodiment is further optimized based on embodiment 2, and the present embodiment focuses on explaining the improvement compared to embodiment 1, and the same parts are not repeated, in the present embodiment, a push rod contact plate 6 is installed at the front end of the hydraulic push rod 4, and a pressure sensor is installed in the push rod contact plate 6. The device for assisting the quenching of the leaf spring further comprises a controller and an infrared sensor 5, wherein the infrared sensor 5 is arranged between the input end of the conveying belt 2 and the hydraulic push rod machine 1, and the controller is respectively connected with the pressure sensor, the hydraulic push rod 4, the infrared sensor 5 and a motor for driving the conveying belt to move.
In this embodiment, three asynchronously-operated hydraulic push rods 4 with pressure sensors are used, each hydraulic push rod 4 is independently controlled by a single chip microcomputer, the pressure sensors can sense resistance change when the steel plate is pushed to the end, when the resistance exceeds a preset value, the single chip microcomputer controls the hydraulic rods to stop pushing forwards and to retract to prepare for pushing next time, as shown in a part A in fig. 3 and a part B in fig. 3, after the three asynchronously-operated hydraulic push rods 4 with pressure sensors complete the actions, the steel plate is placed on the clamping surface of the clamping device 3 in parallel, and abnormal forming of the steel plate can be avoided.
The device provided by the embodiment is suitable for non-equidistant throwing, and the lengths of the steel plates are not required to be equal.
Firstly, an infrared sensor 5 which is a device for measuring the length by infrared rays is additionally arranged on a conveyor belt 2 and is specifically arranged between the input end of the conveyor belt 2 and a hydraulic push rod machine 1, the device aims to measure the length of a high-temperature steel plate when the steel plate passes through the device, a reasonable time for the conveyor belt 2 to pause is calculated by a single chip microcomputer by utilizing the length of the steel plate, the preset speed of the conveyor belt 2 and the distance between the steel plate and the hydraulic push rod machine 1, so that the conveyor belt 2 stops the steel plate at the center of the push rod position of the hydraulic push rod machine 1, and the push rod machine can accurately push the steel plate to a clamping device 3 to ensure that the clamping device 3 carries out a subsequent quenching. The specific implementation calculation mode is as follows:
setting the distance between the infrared sensor 5 and the hydraulic push rod 4 at the middle position of the 3 hydraulic push rods 4 arranged at equal intervals as L;
the conveyor belt 2 moves at a constant speed V; unit: m/s;
the time for the steel plate to pass through the infrared sensor 5 is t 1; unit: s;
