Description

Rotary cultivator cutter make-up machine

Technical field

The utility model belongs to agricultural rotary cultivator field, particularly a kind of rotary cultivator cutter make-up machine.

Background technology

But rotary cultivator replaces animal power arable land big time saver, raises the efficiency as a kind of farm equipment, therefore is present a kind of requisite arable land equipment.Rotary cultivator uses its cutter to be easy to produce fatigue wear for a long time, causes to damage and influence the arable land effect, therefore needs often replacing cutter, and China has very big demand as large agricultural country to rotavator knife.Domestic existing cutter process equipment is to be made of a cover streamline processing unit (plant), cutter at first forms slim blade through rolling mill by the band steel raw material, carry out the operation that cutter bends, puts in order handle, punching, cutting wedge angle, bending more successively, above-mentioned each operation needs process on corresponding apparatus, has caused thus that operation is loaded down with trivial details in the process, energy-output ratio is big; And each operation all needs to be equipped with special workman and operates, and the personnel that cause waste; Owing to, be difficult to guarantee the machining accuracy of cutter through above-mentioned multi-step process.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, reasonable in design, integrates punching, bending, cutting wedge angle, the machining accuracy height, and can save the rotary cultivator cutter make-up machine of the energy and manpower greatly.

The utility model solves its technical problem and takes following technical scheme to realize:

This rotary cultivator cutter make-up machine, this make-up machine is made of frame, crank driving mechanism, pedestal, the bottom of crank driving mechanism installs cope match-plate pattern, install lower bolster on the pedestal, it is characterized in that: the bottom surface at cope match-plate pattern is fixed with a forming convax mould and a prefabricating plate is installed, corresponding prefabricating plate is fixed with a molding concave die on lower bolster, and corresponding forming convax mould is equipped with a cutting platform on lower bolster.

And the bottom surface of described forming convax mould is fixed with a punching post.

And the bottom surface of described forming convax mould is shaped on a moulding concave surface and a upright tangent plane.

And, described prefabricating plate is made of fixed leg, compression spring, pressing plate, wherein an end of four fixed legs all is packed on the cope match-plate pattern, the common level of the other end of four fixed legs is installed pressing plate, on the fixed leg between cope match-plate pattern and the pressing plate, all be set with the compression spring, be shaped on through hole in the position of the relative punching post of pressing plate.

And symmetry is fixed with two positioning seats that clamp cutter on the described molding concave die, is shaped on the punching groove between these two positioning seats, is shaped on the moulding convex surface in molding concave die one side.

Advantage of the present utility model and good effect are:

1. the cutting platform of on the upright tangent plane that is shaped on of the bottom surface of forming convax mould and the lower bolster upright tangent plane position that should forming convax mould being installed matches, and the cutter head can be cut wedge angle when crank driving mechanism presses down; The moulding concave surface that the bottom surface of forming convax mould is shaped on matches with the moulding convex surface that molding concave die one side relevant position is shaped on, can be with the downward bending of the head of cutter when crank driving mechanism presses down; The punching groove that is shaped between the positioning seat on the molding concave die matches with the punching post that the bottom surface of forming convax mould installs, can when crank driving mechanism presses down, the handle of a knife position be stamped out installing hole, realize the one-shot forming of the cutting of rotary cultivator cutter wedge angle, bending, punching thus.

2. the bottom surface of cope match-plate pattern is equipped with prefabricating plate, by the horizontal pressure foot of this prefabricating plate and the compression spring of on its fixed leg, installing, the cutter blank is compressed in advance, when the bending of cutter head, reduce the impact of patrix to cutter, guarantee that the appearance and size after the cutter moulding is accurate, make it meet national standard.

3. this make-up machine is integrated this three process of wedge angle cutting, bending and punching in the past, greatly reduces energy consumption, improves working (machining) efficiency simultaneously, has reduced required staff and has reduced labour intensity, thereby can cut down finished cost significantly, increases the benefit; And, owing to adopt one-time formed method, and the cutter good looking appearance after the moulding, uniform specification, it is strong to change adaptability.

4. the utility model is simple in structure, design science is reasonable, integrates the cutting of cutter wedge angle, bending, punching, can realize the punch forming of cutter through a procedure, the machining accuracy height, and cutter appearance and size is unified, and can save the energy and manpower greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to the cross section enlarged diagram.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

This rotary cultivator cutter make-up machine, constitute by frame 1, crank driving mechanism 2, pedestal 14, crank driving mechanism is carried or is pressed down under the driving of motor (not shown), the bottom of crank driving mechanism installs cope match-plate pattern 3, install lower bolster 13 on the pedestal, its innovative point is: the bottom surface at cope match-plate pattern is fixed with a forming convax mould 4, bottom surface at this forming convax mould is fixed with a punching post 5, one side of forming convax mould bottom surface is shaped on a moulding concave surface 20 and a upright tangent plane 19, and this upright tangent plane is corresponding with the side of cutter wedge angle.One prefabricating plate is installed below the cope match-plate pattern forming convax mould, this prefabricating plate is made of fixed leg 9, compression spring 6, pressing plate 8, wherein an end of four fixed legs all is packed on the cope match-plate pattern, the common level of the other end of four fixed legs is installed pressing plate, on the fixed leg between cope match-plate pattern and the pressing plate, all be set with the compression spring, position at the relative punching post of pressing plate is shaped on through hole 7, but also is shaped on the locating hole 22 of positioning and fixing post on lower bolster.Corresponding prefabricating plate is fixed with a molding concave die 12 on lower bolster, symmetry is fixed with two positioning seats 11 that clamp cutter on this molding concave die, this positioning seat can clamp cutter handle of a knife both sides, the block 10 that can also comprise a position tool shanks terminal position is shaped on punching groove 21 between these two positioning seats.Molding concave die one side be shaped on forming convax mould on the corresponding moulding convex surface 15 of moulding concave surface that is shaped on.Corresponding forming convax mould is equipped with a cutting platform 16 on lower bolster, and the upright tangent plane position that the inboard facade and the forming convax mould of this cutting platform are shaped on is corresponding.
