Abstract
A paper cutting machine knife holder comprises a long-strip-shaped metal seat which is formed by bending a metal plate. The metal seat is in a U shape in the section perpendicular to the length direction of the metal seat, a gap is reserved between an upper wall and a lower wall of the metal seat, the upper wall of the metal seat comprises a wedge-shaped section, the wedge-shaped section is in a wedge shape in the section perpendicular to the length direction of the metal seat, gaps are formed between two ends of the wedge-shaped section and the upper wall of the metal seat, the wedge-shaped section is bended from the lower wall of the metal seat to the upper wall of the metal seat to extend into the gap, and screw holes are arranged on the upper wall and the lower wall of the metal seat. The knife holder is formed by bending the metal plate, the wedge-shaped section is punched on the upper side in a process when the metal plate is bended, and the sharp portion of the wedge-shaped section is bended into the gap formed by U-shaped bending. The paper cutting machine knife holder is simple in processing steps, and reduces production cost. Screws are utilized to locate and fasten blades and the knife holder, so that errors are avoided when the blades are assembled, and the blades can move stably.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to sheet cut machine, particularly a kind of paper cutter tool rest.
Background technology:
In the prior art, the hand paper cutter, 858 type paper cutters as commonly used utilize lever and pressure-loaded mechanism blade to exert pressure, and make blade perpendicular cuts paper.In order to cooperate the cut lengths of paper, blade need to have long length, and during such as the paper of cutting A4 specification, blade needs to have 297 millimeters length at least.The blade of length is when being under pressure, and easily therefore twisting and breaking need to be arranged on blade in the tool rest, and tool rest only exposes the cutting edge part of blade outward, is prevented the torsional deformation of blade by tool rest, and is come the pressure of balanced transmission load maintainer by tool rest.Tool rest is made of train wheel bridge, lower plate and interior lining panel, and interior lining panel is arranged between train wheel bridge and the lower plate, and train wheel bridge is parallel with lower plate, and train wheel bridge, interior lining panel and lower plate are connected securing member and connect, and blade is arranged between the gap of train wheel bridge and lower plate.Because train wheel bridge, lower plate and interior lining panel be independently processing separately, easily produce error during assembling, cause blade unstable, simultaneously, procedure of processing is loaded down with trivial details, and production cost is higher.
Summary of the invention:
The purpose of this utility model is to provide a kind of paper cutter tool rest, the technical problem that described this paper cutter tool rest will solve that hand in the prior art is loaded down with trivial details with paper cutter tool rest procedure of processing, easily produce error during assembling, production cost is higher.
This paper cutter tool rest of the present utility model, the metal pedestal that comprises a strip, wherein, described metal pedestal is made of a metallic plate bending, metal pedestal is U-shaped in the cross section perpendicular to its length direction, be provided with the gap between the upper wall of metal pedestal and the lower wall, include a wedge-shaped segment in the upper wall of metal pedestal, described wedge-shaped segment is wedge shape in the cross section perpendicular to the metal pedestal length direction, be provided with the crack between the two ends of wedge-shaped segment and the upper wall of metal pedestal, wedge-shaped segment from the bending of upper wall direction from the upper wall of metal pedestal to metal pedestal and extend to the described gap, be provided with screw hole in the upper wall of metal pedestal and the lower wall.
Further, be provided with screw in the described screw hole, upper wall and the lower wall of the equal connection metal seat of any one described screw.
Operation principle of the present utility model is: paper cutter, such as 858 commonly used type paper cutters, when using tool rest of the present utility model, blade is inserted gap between metal pedestal upper wall and the lower wall, and utilize the screw location of the upper wall, lower wall and the blade that pass metal pedestal.Sharp parts and the blade of wedge-shaped segment are adjacent, and produce the pressure of blade side under the pulling force of screw, and blade is fastened in the metal pedestal.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes a metallic plate to do to consist of the paper cutter tool rest after the U-shaped bending, in rushing the process of curved metallic plate, stamp out a wedge-shaped segment at upside simultaneously, the sharp-pointed section of wedge-shaped segment is folded in the gap that U-shaped bending forms afterwards, the utility model procedure of processing is simple, has reduced production cost.Utilize screw with blade and tool rest location and fastening, can not produce error, the blade having stable behavior during blade assembling.

The specific embodiment:
Embodiment 1:
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, paper cutter tool rest of the present utility model, the metal pedestal 1 that comprises a strip, wherein, described metal pedestal 1 is made of a metallic plate bending, metal pedestal 1 is U-shaped in the cross section perpendicular to its length direction, be provided with the gap between the upper wall 11 of metal pedestal 1 and the lower wall 12, include a wedge-shaped segment 13 in the upper wall 11 of metal pedestal 1, described wedge-shaped segment 13 is wedge shape in the cross section perpendicular to metal pedestal 1 length direction, be provided with the crack between the upper wall 11 of the two ends of wedge-shaped segment 13 and metal pedestal 1, wedge-shaped segment 13 from the bending of upper wall 11 directions from the upper wall 11 of metal pedestal 1 to metal pedestal 1 and extend to the described gap, be provided with screw hole 2 in the upper wall 11 of metal pedestal 1 and the lower wall 12.
Further, be provided with the screw (not shown) in the described screw hole 2, upper wall 11 and the lower wall 12 of the equal connection metal seat 1 of any one described screw.
The operation principle of the present embodiment is: paper cutter, such as 858 type paper cutters commonly used, when using tool rest of the present utility model, with the gap between blade (not shown) insertion metal pedestal 1 upper wall 11 and the lower wall 12, utilize the screw location of the upper wall 11, lower wall 12 and the blade that pass metal pedestal 1.Sharp parts and the blade of wedge-shaped segment 13 are adjacent, and produce the pressure of blade side under the pulling force of screw, and blade is fastened in the metal pedestal 1.
