Description
TECHNICAL FIELD
[0001] The utility model relates to a new material technical field, in particular to a hole cutter for sponge punching. BACKGROUND
[0002] Sponges are made from wood cellulose fibers or foamed plastic polymers. For low-density polyether (non-water-absorbing sponge), polyvinyl alcohol (high water-absorbing material, no obvious pores) and polyester.
[0003] And the sponge has different shapes in the use process, such as block, strip and belt, and punching needs to be carried out on the sponge in the use process, so as to be suitable for various occasions. At present, the punching mode on the sponge still stays in manual use of cutters and scissors to complete. The above-mentioned punching mode has different hole diameters, and there is still punching damage. It is difficult to reach the standard during use, and manual cutting is time-consuming and laborious, and occupies the production time of workers. According to the needs, the application discloses a hole cutter for sponge punching. UTILITY MODEL CONTENTS
[0004] The utility model aims at the prior art, and provides a hole cutter for sponge punching.
[0005] The utility model is realized through the following technical scheme: a hole cutter for sponge punching, including cutter body, the cutter body lower extreme is integratively connected cutting knife, the cutting knife is provided with concentric hole, the concentric hole is provided with pressing sheet, the pressing sheet upper end is connected with core rod, the core rod is equipped with spring, the core rod upper end is connected with end cap, the end cap is arranged in screw hole, the screw hole is arranged on the cutter body upper end, the screw hole is connected with stud, the stud upper end is integratively connected with handle.
[0006] As a further improvement of the above-mentioned scheme, the screw column and the handle are provided with a cap hole.
[0007] The end cap is displaced upward under the pushing of the core rod, and a sliding space is reserved.
[0008] As a further improvement of the above-mentioned scheme, the spring is arranged in the concentric hole, and the upper end of the spring abuts against the upper end of the concentric hole, and the lower end of the spring abuts against the upper end surface of the pressing sheet.
[0009] The pressing sheet is displaced upward under the pushing of the excess material cut by the annular blade, and the core rod and the end cap are also displaced upward. The spring is compressed in the concentric hole and becomes shorter. The end cap is displaced from the lower end to the upper end in the cap hole. If the excess material is not pushed upward by external force, the excess material will be pushed out of the concentric hole by the pressing sheet under the action of the spring.
[0010] As a further improvement of the above-mentioned scheme, the cutting knife is arranged in a tapered cylinder structure with a large upper end and a small lower end, and the lower end is provided with an annular blade for cutting the sponge. The excess material cut after punching the sponge is accommodated in the concentric hole.
[0011] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The blade is subjected to force by the handle, and the sponge is cut by the annular blade at the lower end of the cutter. The excess material generated by cutting and punching is contained in the concentric hole. The pressure plate is displaced and pushed out by the force of the spring. At the same time, the displacement of the pressure plate is guided by the displacement of the core rod to ensure the stable displacement of the pressure plate. In addition, the end cap prevents the core rod from being unable to detach from the blade body under the push of the spring. Attached Figure Description
[0012] Fig. 1 This is a schematic diagram of the structure of this utility model.
[0013] Fig. 2 This is a cross-sectional structural diagram of the present invention. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figs. 1-2 As shown, a perforating tool for sponge includes a tool body 1. A cutter 2 is integrally connected to the lower end of the tool body 1. A concentric hole 4 is provided inside the cutter 2. A pressure plate 5 is provided inside the concentric hole 4. A core rod 6 is connected to the upper end of the pressure plate 5. A spring 7 is fitted on the core rod 6. An end cap 8 is connected to the upper end of the core rod 6. The end cap 8 is provided inside a screw hole 9. The screw hole 9 is provided at the upper end of the tool body 1. A stud 10 is threadedly connected to the screw hole 9. A tool handle 11 is integrally connected to the upper end of the stud 10.
[0016] As a further improvement to the above solution, a cap hole 12 is provided inside the stud 10 and the tool holder 11;
[0017] This is for the sliding space reserved for the end cap 8 to move upward under the push of the core rod 6.
[0018] As a further improvement to the above solution, the spring 7 is disposed in the concentric hole 4, and the upper end of the spring 7 abuts against the upper end of the concentric hole 4, and the lower end of the spring 7 touches the upper end surface of the pressure plate 5.
[0019] The pressure plate 5 is pushed upward by the residual material cut by the annular blade 13. At the same time, the core rod 6 and the end cap 8 also move upward. The spring 7 is compressed and shortened in the concentric hole 4. The end cap 8 moves from bottom to top into the cap hole 12. If there is no external force pushing the residual material upward, the residual material will be pushed away from the concentric hole 4 by the pressure plate 5 under the action of the spring 7.
[0020] As a further improvement to the above solution, the cutter 2 is configured as a conical structure with a larger upper end and a smaller lower end, and the lower end is provided with an annular blade 13 for cutting the sponge. The remaining material after cutting through the sponge is contained in the concentric hole 4.
[0021] The working principle of a sponge punching cutter: The cutter is mounted on a punching device via a handle 11. The handle 11 applies force to the cutter body 1, and the annular blade 13 at the lower end of the cutter 2 cuts the sponge, forming a hole in the sponge that matches the annular blade 13. The excess material generated from the cutting and punching is contained in the concentric hole 4. Without being pushed upward by an external force, the pressure plate 5 is displaced and pushed out by the force of the spring 7. At the same time, the displacement of the pressure plate 5 is guided by the displacement of the core rod 6, ensuring the smooth displacement of the pressure plate 5. In addition, the end cap 8 prevents the core rod 6 from being unable to detach from the cutter body 1 under the push of the spring 7.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
