Abstract
The invention discloses a knife back forming machine, which comprises an upper die, a lower die, a fixed side die, a movable side die, a main hydraulic device and an auxiliary hydraulic device, wherein the main hydraulic device and the auxiliary hydraulic device are fixed on a base; the upper die is fixed on a plunger end of the main hydraulic device; the bottom shape of the upper die is adaptive to the shape required by the top of the knife back; the lower die is fixed on the base; a knife edge slot used for fixing a knife is arranged above the lower die; the fixed side die is fixed on the base; the movable side die is fixed on a plunger end of the auxiliary hydraulic device; and the combined shape of the opposite surfaces of the fixed side die and the movable side die is adaptive to the required shaped by the cross section of the knife. According to the knife back forming machine disclosed by the invention, a purpose of thickening the knife back can be realized, and the knife back forming machine is regular and beautiful in forming. When the knife back forming machine disclosed by the invention is adopted, the knife back of the knife can be processed within 10 seconds, no coal needs to be fired, the energy is saved, the environment is protected, the production efficiency is improved, the labor intensity is lowered, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of tooling equipment, particularly relate to a kind of knife back forming machine.
Background technology
The similar cutter used in everyday such as kitchen knife, its knife back shape and thickness are extremely important for use, and consumer generally likes the knife back to thicken, can increase texture like this, energy is laborsaving.But the knife back thickeies in the prior art is a difficult problem: existing punching press cutter can not solve the problems of the technologies described above, and the made cutter knife back is equally thick with blade; Hand forging makes cutter, although can thicken the knife back, irregular owing to not having cutting die to be thus shaped, and efficiency is low, the thick embryo processing of the general knife back needing just to complete 1 cutter for 2 minutes; Need in process to burn coal, energy consumption is large, seriously polluted.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can increase knife back thickness, the rule that is shaped, high, the energy-conserving and environment-protective of efficiency knife back forming machine.
In order to solve the problems of the technologies described above, knife back forming machine of the present invention comprises upper die and lower die, fixing side form, movable side form, the main hydraulic means being fixed on support and auxiliary hydraulic means; Described patrix is fixed on the plunger termination of main hydraulic means, and above its lower square shape and the knife back, required form adapts to; Described counterdie is fixed on support, is provided with the edge of a knife groove for dead knife above it; Described fixing side form is fixed on support; Described movable side form is fixed on the plunger termination of auxiliary hydraulic means; Adapting to shape required for the shape of opposite combination and the cross section of cutter of described fixing side form and movable side form.
As further improvement, also comprise fixed electromagnet and movable electro-magnet, described fixed electromagnet is fixed on support and is close to fixing side form and is fixedly connected with, the plunger termination being close to movable side form that described movable electro-magnet is fixed on auxiliary hydraulic means is fixedly connected with, and described movable side form is connected to the plunger of auxiliary hydraulic means by movable electro-magnet.
Adopt structure of the present invention, owing to being provided with cutting die, adapting to shape required for the shape of opposite combination and the cross section of cutter of fixing side form and movable side form, during work, knife back part is heated, cutter is placed in cutting die, the edge of a knife snaps in the edge of a knife groove of counterdie down, and movable side form inwardly extrudes lives cutter holder together with fixing side form, and the knife back is pressed into required form toward pressing down by patrix, achieve the object that the knife back thickeies, and it is regular, attractive in appearance to be shaped.Adopt knife back forming machine of the present invention to process, the knife back processing of 1 cutter can be completed 10 seconds, improve production efficiency, reduce labour intensity, reduce production cost, and not need to burn coal, energy-conserving and environment-protective.Structure of the present invention is simple, and manufacture easy to use, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
As shown in Figure 1, knife back forming machine of the present invention comprises patrix 5, counterdie 9, fixing side form 2, movable side form 6, the main hydraulic means being fixed on support and auxiliary hydraulic means.Patrix 5 is fixed on plunger 4 termination of main hydraulic means, and above its lower square shape and the knife back, required form adapts to.Counterdie 9 is fixed on support, is provided with the edge of a knife groove for dead knife above it.Fixing side form 2 is fixed on support.Movable side form 6 is fixed on plunger 8 termination of auxiliary hydraulic means.Adapting to shape required for the shape of opposite combination and the cross section of cutter of fixing side form 2 and movable side form 6.
In order to the cutter in fixed die further in process, when pressing down to prevent patrix, movable side form is squeezed and cause knife back out-of-shape, fixed electromagnet 1 and movable electro-magnet 7 can be provided with.Fixed electromagnet 1 is fixed on support and is close to fixing side form 2 and is fixedly connected with.Plunger 8 termination being close to movable side form 6 that movable electro-magnet 7 is fixed on auxiliary hydraulic means is fixedly connected with.Movable side form 6 is connected to the plunger 8 of auxiliary hydraulic means by movable electro-magnet 7.Produce suction after electromagnet energising fixing side form and movable side form to be sucked, can cutter better in fixed die.
In order to need to be convenient for changing patrix according to the shape in different knife back face, patrix fixed block 3 can also be provided with.Patrix fixed block 3 be fixed on main hydraulic means plunger 4 termination, be provided with patrix holddown groove below it, patrix 5 is fixed in this patrix holddown groove.
The above-mentioned mode that is fixedly connected with is prior art, and the conventional threaded fastener such as bolt, stud can be adopted to connect.
In order to the work realizing electromagnet is coordinated mutually with the stroke of auxiliary hydraulic means plunger, the plunger 8 of auxiliary hydraulic means can be provided with gauge tap, and this gauge tap is electrically connected with the Drive and Control Circuit of fixed electromagnet, movable electro-magnet.
