Abstract
The invention relates to a cutting tool, in particular to a high-speed transverse cutter suitable for continuous production and a cutting method thereof. The high-speed transverse cutter comprises a fixed lower cutter and a rotatable upper cutter, wherein the lower cutter edge is a straight line; and the upper cutter is provided with an upper cutter edge which can perform shear-type cutting with the lower cutter edge in a point-contact manner. During cutter setting, the lower cutter is manually placed close to the upper cutter; when the edge clearance is zero, the cutter has zero friction and is only subjected to the friction of a cut material; and meanwhile, due to the shear-type cutting, the cutting resistance is low, and the cutter has long service life. When the upper and lower cutter edges are in relatively low interference, the cutting resistance mainly comes from the friction between the upper and lower cutter edges; and after a certain time of running, the clearance between the upper and lower cutter edges is zero, thus achieving the optimum cutting effect. Due to the shear-type cutting, the high-speed transverse cutter provided by the invention has the characteristics of small resistance, simple structure, long service life and high rotation speed up to 36,000 times per hour, and is easy to install and debug.
Description
Technical field
The present invention relates to cutting tool, specifically a kind of suitable quantity-produced high-speed transverse cutter and cutting method thereof.
Background technology
In a lot of fields, all need to use cutting knife and come cutting material, for example when exploitation RFID (REID) electronic tag compounding machine, will need to develop revolving knife is that the RFID electronic tag (INLAY) of coiled material cuts into single INLAY with the supplied materials mode, and pulls open after the distance between each INLAY compound with the art paper with printed patterns of gluing.
At present, external RFID electronic tag compounding machine has two kinds of cutting knifes, and a kind of is that German MELZER maschrnenbau GmbH produces, the equipment that the said firm produces adopts the mode of similar chopper, the electronic tag step motion, the up and down cutter position control accuracy of cutting knife requires high, production capacity approximately per hour 3000 times; Another kind is the equipment that German Bi Nuo company produces, what adopt is rotary cutter, being cut the material below is chopping block, the top is the blade that is clamped on the rotating shaft, and when cutting off material, the distance of cutting knife and chopping block is close to zero, be equivalent to material is cut disconnected, device structure is complicated, and manufacturing and assembly difficulty are large, and Cutting Drag is large.
Scissors is the manual crosscut cutter in daily, during cutting up and down cutting edge be the some contact, material is cut off by pointwise, Cutting Drag is little, effect is more satisfactory.How the cutting mode with scissors is applied on the RFID electronic tag compounding machine, also to guarantee simultaneously to make install simple and convenient, cutter life is long, has become people's problem demanding prompt solution.
Summary of the invention
Large, the ineffective problem of Cutting Drag that exists in order to solve existing cutting knife the object of the present invention is to provide that a kind of Cutting Drag is little, high-speed transverse cutter and the cutting method thereof of cutter life length, good cutting effect, high efficiency.
The objective of the invention is to be achieved through the following technical solutions:
High-speed transverse cutter of the present invention comprises fixing lower cutter and rotating upper slitter, and wherein descending edge is straight line, and described upper slitter has the upper slitter cutting edge that forms shearing cutting with a way of contact and lower edge.
Wherein: described lower edge abuts on the face of cylinder at upper slitter cutting edge place, as a bus on this face of cylinder; Described upper slitter cutting edge is the helix on its face of cylinder, place; Upper slitter is cylindrical, and the face of cylinder at upper slitter cutting edge place keeps 38 ° of angles in radial section, and the radius of all the other positions of upper slitter is less than the radius on the face of cylinder, upper slitter cutting edge place; One end of described upper slitter is installed on the second end face slab, links to each other with drive unit, and the other end of upper slitter is connected with an end of connecting plate by the first end face slab, and the other end of connecting plate is installed on the second end face slab; Described lower cutter is installed in the bottom of connecting plate; Have groove on the connecting plate, be cut material and passed through by groove; Lower cutter level is installed on the installed surface of connecting plate, and the installed surface of lower cutter is parallel with the axis of upper slitter; The two ends of upper slitter are installed in rotation on first and second end face slab by bearing respectively, one end of upper slitter passes key by the second end face slab and is connected with belt wheel, this belt wheel by synchronous cog belt be installed in the second end face slab on motor output shaft on belt wheel be connected; Be provided with bearing gland to this end bearing axial location at the first end face slab.
The cutting method of high-speed transverse cutter of the present invention: lower cutter is fixed, upper slitter is rotatable, lower edge is straight line, the upper slitter cutting edge is the helix on its face of cylinder, place, be cut material by the groove feeding, when upper slitter rotated cutting, upper and lower edge remained unchanged with form and the distance of a contact, forms shearing cutting.
Wherein: the face of cylinder at upper slitter cutting edge place keeps 38 ° of angles in radial section, and the radius of all the other positions of upper slitter is less than the radius on the face of cylinder, upper slitter cutting edge place, and making just, the cutting material can pass through between the cutter up and down; The angle of upper slitter cutting edge in radial section is 25 ° of angles, and upper slitter rotates 25 ° and finishes cutting, continues up and down cutter separation of ROT13 ° realization again.
Advantage of the present invention and good effect are:
The present invention is when tool setting, and lower cutter is by the manual upper slitter that is close to, and cutter only bore the friction that is cut material without friction when the cutting edge gap was zero; Because being shearing cutting, Cutting Drag is little simultaneously, and cutter life is long.When edge had less interference up and down, Cutting Drag was mainly from the up and down friction of edge, and after break-in after a while, the edge gap is zero up and down, and cutting effect reaches optimum state.Characteristics of the present invention are shearing cuttings, and resistance is little, and rotating speed is high, can reach per hour 36,000 times, and simple in structure, installation and debugging are easy, long service life.
Cutting method of the present invention is that upper slitter rotation, lower cutter are fixed, and is cut the material continuous feed, with the formula cutting material of shearing, high efficiency.
