DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0027] Please refer to Figures 1-4 The application provides a technical solution: a straightening device for sheet metal part machining, which comprises a base 1, a rack 2 fixed above the base 1 through four slide columns 201, a first electric oil cylinder 3 installed at the upper middle part of the rack 2, and a pressing plate 4 movably installed between the lower end of the first electric oil cylinder 3 and the four slide columns 201. A ceramic electric heating plate 5 is embedded below the pressing plate 4 at the upper middle part of the base 1. Side grooves 101 are formed at the middle parts of the left and right ends of the base 1. First trapezoidal sliders 6 are movably installed inside the side grooves 101. The first trapezoidal sliders 6 are provided with clamping parts for fixing the end parts of sheet metal parts. The upper end of the pressing plate 4 is provided with a spring supporting part for cooperating with the first trapezoidal sliders 6.

[0028] Specifically, the elastic supporting part comprises slide buckles 401 symmetrically fixed on the left and right sides of the upper end of the pressing plate 4, a second trapezoidal slide block 8 movably installed on the inner side of the slide buckle 401, a baffle plate 402 fixed on the upper end of the pressing plate 4 and close to one side of the second trapezoidal slide block 8, and a spiral extrusion spring 9 symmetrically installed between the baffle plate 402 and the second trapezoidal slide block 8. The spiral extrusion spring 9 can exert an elastic extrusion force horizontally outward on the first trapezoidal slide block 6 when the first trapezoidal slide block 6 and the second trapezoidal slide block 8 contact each other. The first trapezoidal slide block 6 and the second trapezoidal slide block 8 are both in a right trapezoidal structure, and the inclined surfaces of the first trapezoidal slide block 6 and the second trapezoidal slide block 8 are in close contact with each other. The structure converts the vertical movement of the pressing plate 4 into the horizontal sliding contact between the first trapezoidal slide block 6 and the second trapezoidal slide block 8, so that the sheet metal part is in a tension state before flattening processing.

[0029] Specifically, the material clamping part comprises a material discharging hole 601 transversely and longitudinally arranged in the middle of the first trapezoidal slide block 6, a second electric oil cylinder 7 installed at the lower end of the first trapezoidal slide block 6, and a material clamping plate 701 movably installed between the upper end of the second electric oil cylinder 7 and the material discharging hole 601. The lower end of the material clamping plate 701 is symmetrically fixedly connected with two vertical limiting columns 702 penetrating through the first trapezoidal slide block 6. The limiting columns 702 improve the stability of the second electric oil cylinder 7 driving the material clamping plate 701 to move up and down.

[0030] Specifically, the front end, the lower end and the rear end of the first trapezoidal slide block 6 are rotatably installed with pulleys 602, and the left and right ends of the base 1 are provided with wheel grooves 102 for accommodating the pulleys 602. The comprehensive arrangement of the pulleys 602 and the wheel grooves 102 improves the stability of the horizontal sliding adjustment of the first trapezoidal slide block 6 in the side groove 101 and reduces the friction of the horizontal sliding adjustment of the first trapezoidal slide block 6.

[0031] Specifically, an electric control box 10 is installed on the right side of the front end of the base 1. The output end of the electric control box 10 is electrically connected with the input ends of the first electric oil cylinder 3, the ceramic electric heating plate 5 and the second electric oil cylinder 7. The arrangement of the electric control box 10 facilitates the power supply and control of the first electric oil cylinder 3, the ceramic electric heating plate 5 and the second electric oil cylinder 7 by the operator.

[0032] Working principle: when using, two first trapezoidal sliders 6 are synchronized in the side groove 101 and reset to the initial state, then the metal plate is horizontally inserted between the two first trapezoidal sliders 6 above the base 1, at this time, the second electric oil cylinder 7 can be controlled to be powered on by operating the electric control box 10, the second electric oil cylinder 7 can drive the clamping plate 701 to move upward, so as to fix the end of the metal plate on the first trapezoidal slider 6, after the preliminary work is completed, the operator can operate the electric control box 10 to control the first electric oil cylinder 3 and the ceramic electric heating plate 5 to work, the first electric oil cylinder 3 can drive the pressing plate 4 to move downward as a whole, the second trapezoidal slider 8 on the pressing plate 4 will first contact the first trapezoidal slider 6 on the base 1, under the contact and sliding action between the first trapezoidal slider 6 and the second trapezoidal slider 8, the first trapezoidal slider 6 can slide horizontally outward, at the same time, the second trapezoidal slider 8 moves horizontally inward to extrude the spiral extrusion spring 9, the spiral extrusion spring 9 will generate an opposite elastic extrusion force on the first trapezoidal slider 6, so that the metal plate before flattening processing is in a tension state, when the pressing plate 4 contacts and extrudes the metal plate downward, the ceramic electric heating plate 5 can uniformly heat the metal plate, so as to complete the traction and hot pressing comprehensive flattening treatment of the metal plate.

[0033] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
