Technical Field

[0001] The utility model belongs to the technical field of guide rails, and in particular relates to a novel guide rail structure. Background Art

[0002] In the automotive stamping products industry, facing increasingly severe competition and workers' wages increasing year by year, the product qualification rate and the efficiency and stability of stamping machines are crucial. At the same time, in order to reduce the welding volume of stamping parts, the main manufacturers are producing more and more special-shaped stamping products, which leads to higher and higher demands on the anti-eccentric load capability of the stamping machines. How to improve the parallelism and efficiency of the frame-type stamping machines during stamping and improve the anti-eccentric load capability of the workbench during stamping has become the primary task of the machine tool factory.

[0003] The existing frame-type hydraulic punch press adopts a 90-degree right-angle guide rail structure, which is distributed on the four columns of the machine tool to form a four-corner eight-sided structure. The two ends of the slide are adjusted with screws, and the slide is extruded outward all around, resulting in each guide rail surface being able to only withstand extrusion pressure. When the workbench of this structure is subjected to an eccentric load, one of the guide rails is subjected to a larger force, and the other three guide rails only play an auxiliary role, which can easily cause the workbench to move and deviate during stamping, affecting the qualification rate of stamped products.

[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 5 As shown, a new guide rail structure includes a guide rail body 12 installed in a stamping device. The stamping device includes a base 1. The upper end surfaces of the left and right sides of the base 1 are respectively fixedly connected to a left bracket 3 and a right bracket 4. The top ends of the left bracket 3 and the right bracket 4 are fixedly connected to a top cover 8. A stamping assembly is installed on the top cover 8. The stamping assembly includes five cylinders 9 fixedly installed on the lower surface of the top cover 8, four of which are distributed in a matrix, and another cylinder 9 is arranged between the above four cylinders 9. The base 1, the left bracket 3, the right bracket 4 and the top cover 8 together form a closed frame structure.

[0023] The left and right brackets 3 and 4 are fixedly connected to the bottom ends with legs 2. The four legs 2 are distributed in a matrix. The bottom ends of the legs 2 are covered with rubber gaskets. The legs 2 are used to elevate the left and right brackets 3 and 4. The rubber pads can isolate the ground from moisture and reduce corrosion to the left and right brackets 3 and 4.

[0024] A punching table 5 for supporting the workpiece is fixedly connected to the upper surface of the base 1 below the slide 10. A horizontally arranged support plate 6 is fixedly connected to the right bracket 4. One end of the support plate 6 extends into the closed frame structure and corresponds to the end of the punching table 5. Multiple sets of rollers 7 are rotatably connected to the upper surface of the support plate 6. When loading, the user can place the workpiece on the rollers 7, and then push the workpiece to move along the rollers 7 to transport the workpiece to the punching table 5, which makes it easier for the user to load the material.

[0025] There are two groups of guide rail bodies 12, and the two groups of guide rail bodies 12 are respectively vertically mounted on the inner side walls of both ends of the left bracket 3 and the right bracket 4. The two adjacent guide rail bodies 12 in each group are provided with an inclined surface, and the inclined surface forms a seventy-degree angle with the side wall of the guide rail body 12 close to the stamping assembly. The output end of the stamping assembly is fixedly connected to the slide 10, and wear-resistant blocks 13 are installed on both ends of the left and right sides of the slide 10. A three-degree angle is formed between the wear-resistant block 13 and the slide 10. An adjusting bolt 16 is provided on one side of the wear-resistant block 13. The middle section of the adjusting bolt 16 passes through the mounting plate 11 and is screwed to the mounting plate 11. The end of the adjusting bolt 16 is connected to the wear-resistant block 13. The user can adjust the distance between the wear-resistant block 13 and the mounting plate 11 by rotating the adjusting bolt 16, so as to facilitate the adjustment of the position of the wear-resistant block 13 after the wear-resistant block 13 is worn;

[0026] The left and right ends of the slide 10 are fixedly connected to the mounting plates 11 , and the mounting plates 11 are provided with connecting bolts 15 . The connecting bolts 15 pass through the mounting plates 11 and are screwed and fixed to the guide blocks 14 , so that the guide blocks 14 are fixed to the slide 10 through the mounting plates 11 .

[0027] It should be noted that this new type of guide rail structure, when in use, the two groups of guide rail bodies 12 are respectively installed on the inner walls of the left bracket 3 and the right bracket 4, and then the guide block 14 is fixed to the slide 10 by connecting bolts 15 and the mounting plate 11, and the oil cylinder 9 can be started to push the slide 10 to slide down along the guide rail body 12 for stamping work. Since the adjacent sides of the two guide rail bodies 12 in each group are provided with inclined surfaces, the inclined surfaces and the side wall of the guide rail body 12 close to the stamping component form a seventy-degree angle, and the end of the guide block 14 away from the slide 10 extends toward the guide rail body 12 to form a protrusion that fits with the inclined surface of the guide rail body 12. The ends of the guide blocks 14 installed at both ends of the slide 10 wrap the inclined surfaces on the guide rail body 12 from the outside to the inside. When the stamping table 5 is subjected to an offset load, when one of the guide rail bodies 12 is subjected to extrusion pressure, the other three guide rail bodies 12 can provide corresponding lateral pulling force to ensure the parallelism of the workbench 5 during stamping and improve the product qualification rate.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
