Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam processing, in particular to a positioning tool for foam cutting. Background Art
[0002] Foam is a material made of foamed plastic particles. It has a series of characteristics such as elasticity, light weight, fast compression and fixation, easy to use, flexible bending, ultra-thin volume, and reliable performance. In the fields of automotive interiors, electronic product circuit boards, and toy safety packaging, foam not only has the functions of sound insulation, heat insulation, and shock absorption, but also plays a role in buffering and protection. In addition, foam is also widely used in home decoration. For example, sound insulation foam can be used in the walls, roofs, and floors of houses to play a role in sound insulation and heat preservation. Some furniture seats also use foam materials to increase comfort and stability.
[0003] Foam cutting is an important process step. To ensure the accuracy and safety of cutting, the foam needs to be fixed before cutting. The traditional fixing method is to clamp and fix it from both sides through the cooperation of studs, clamps and knobs, which is convenient for thick foam, but the positioning method is relatively single. When it is necessary to cut and fix multiple layers of thin foam, the clamping on both sides has certain limitations. Utility Model Content

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] Combined with Figure 1 A positioning tool for foam cutting includes a mounting plate 1, wherein the four corners of the mounting plate 1 are provided with threaded mounting holes 2, and the mounting plate 1 is provided with an anti-slip rubber pad 13.
[0026] Through the above structure, the positioning tool can be directly installed on the working surface of any cutting machine tool using the threaded mounting hole 2, which is convenient to use. The anti-skid rubber pad 13 can play a certain anti-skid role and further increase the stability during foam cutting.
[0027] Combined with Figure 2 and attached Figure 4 At least one spring 9 is provided on one side of the fixed block 3, a push plate 10 is provided at one end of the spring 9, limit plates 14 are provided on both sides of the push plate 10, and limit bolts 15 are inserted on the limit plates 14. Limit holes 16 for cooperating with the limit bolts 15 are provided at both ends of the mounting plate 1, sliders 11 are provided on both sides of the bottom end of the push plate 10, and slide grooves 12 for cooperating with the sliders 11 are provided on both sides of the top end of the mounting plate 1. There are three springs 9 in total, and the two ends of the spring 9 are fixedly connected to the fixed block 3 and the push plate 10 respectively.
[0028] Through the above structure, the spring 9 and the push plate 10 can be used to clamp and fix the two sides of the foam, and the elastic force of the spring 9 can be used to buffer the push plate 10, thereby protecting the foam and avoiding deformation due to excessive extrusion. In addition, with the guidance of the slider 11 and the slide groove 12, it can be ensured that the push plate 10 can move smoothly laterally, and at the same time, the limit plate 14, the limit hole 16 and the limit bolt 15 can be used to conveniently lock the push plate 10.
[0029] Embodiment 2
[0030] Combined with Figure 1 and attached Figure 3A fixing block 3 is provided on both sides of the top of the mounting plate 1, a groove 4 is provided on the top of the fixing block 3, a pressure plate 5 is hingedly provided at one end of the groove 4, a fixing column 6 is provided in the groove 4, a knob 7 for rotation connection is provided on the top of the fixing column 6, and a through hole 8 for matching with the knob 7 is provided on the pressure plate 5.
[0031] Through the above mechanism, the pressing plate 5 is laid flat, the knob 7 at the top of the fixing column 6 passes through the through hole 8, and the knob 7 is turned so that the knob 7 is perpendicular to the through hole 8, so that the pressing plate 5 can be directly fixed. The pressing plate 5 can be used to support the top of both sides of the foam and fix the foam vertically.
[0032] Combined with Figure 2 The side view cross-sectional size of the through hole 8 is the same as the front view cross-sectional size of the knob 7, and one side of the pressing plate 5 and the pushing plate 10 are both affixed with an anti-slip film.
[0033] Through the above mechanism, since the side view cross-sectional size of the through hole 8 is the same as the main view cross-sectional size of the knob 7, it is not only convenient for the knob 7 to pass through the through hole 8, but also convenient for rotating the knob 7 to press the pressure plate 5, and the whole is stable. In addition, one side of the pressure plate 5 and the push plate 10 are both affixed with an anti-slip film, which can further increase the friction force, and the foam can be firmly clamped as a whole.
[0034] When the utility model is implemented:
[0035] When thick foam needs to be cut, the pressure plate 5 is directly reversed to face outward, the push plate 10 is moved to both sides respectively, the slider 11 slides in the slide groove 12, squeezing the spring 9, and then the foam is directly placed on the anti-slip rubber pad 13. The spring 9 rebounds with elastic force, which can directly clamp and fix the foam horizontally. In addition, the spring 9 can buffer and protect the foam to avoid deformation caused by excessive squeezing, making cutting convenient.
[0036] When it is necessary to cut multiple layers of thin foam, move the push plates 10 on both sides to the sides, insert the limit bolts 15 into the limit plates 14 and extend them into the limit holes 16, and the push plates can be directly locked on both sides. Then turn the knob 7 to a vertical state, and then lay the pressing plate 5 flat, so that the knob 7 passes through the through hole 8 and is pressed into the groove 4, and the two sides of the multi-layer foam are pressed and held, and then the knob 7 is turned so that the knob 7 and the through hole 8 are in a vertical state, and the pressing plate 5 can be directly fixed.
[0037] The whole device can not only clamp and fix the two sides of thick foam, but also position the top two sides of multiple layers of thin foam, and the usage is flexible.
