Description
Technical field
This utility model relates to a kind of agricultural hoe, particularly relates to the new hoe that seedstalk trousers are integrated with hoe plate.
Background technology
Traditional hoe is by uprooting plate and hoe hoop forms, and hoe hoop is welded on out on hoe plate, and this hoe is due to hoe hoop and hoe plate
Welding, mechanical strength is relatively low, and service life is shorter.
Chinese patent CN21191964Y discloses one " hoe ", and its structural feature is: hoe plate and hoe hoop are welded as one
Body, hoe plate bottom, the same backing strip of hoe hoop bottom welding, make hoe plate be welded as a whole with hoe hoop, due to uproot plate be still that with hoe hoop
Welding Structure, its mechanical strength is the highest.
Chinese patent CN101683030B discloses one " hoe of hoe plate back welding casting muscle ", its structural feature
It is: ... one end and the hoe hoop of hoe plate are welded as a whole, and casting muscle is equal with hoe back in being filled in the lottery of hoe back
Welding.Although the setting of casting muscle adds mechanical strength, but limited by the structure, still there is weak point, show: hoe plate
One end weld life-time service with hoe hoop, hoe hoop easily departs from hoe plate, and durability is poor, and service life is short.
And traditional system hoe technique typically uses the high-power die forging method of bloom, handle trousers are welded on hoe plate, this work
Skill is complicated, and labor intensity is big, inefficiency.
Summary of the invention
In order to solve the above-mentioned deficiency of existing hoe and production technology, goal of the invention one of the present utility model
Being to provide a kind of hoe plate to be integrated with handle trousers, robust new hoe, two are to provide a kind of new hoe handle
The Hot drawing technique of trousers.
Solve above-mentioned technical problem and use technical scheme:
A kind of new hoe, is mainly made up of hoe plate and handle trousers, and described hoe plate is integrated with handle trousers, in the back side of hoe plate
Top is provided with groove, corresponding with groove, forms projection in the front of hoe plate, and described groove, protruding upper end are connected with handle trousers, institute
Stating handle trousers is circular ring structure, the turned-out expansion of outer rim of handle trousers, forms flange.
Preferably, described groove, projection are up big and down small " V " word vertebra shape structure.
Preferably, described groove, protruding upper end are integrated with handle trousers.
Using technique scheme, compared with prior art, this utility model uses manganese alloy hot strip steel drawing and forming,
The production prices of raw materials are low, and technique is simple, low cost of manufacture.Hoe plate is integrated with handle trousers, and hoe overall mechanical strength is high, firm
Durable.Positive and negative " V " the word vertebra shape texture grooves of hoe plate and protruding setting, serve the effect of reinforcement, make hoe plate stress
Uniformly.And handle trousers are provided with the outer rotating edge being integrated with, when operation runs into firm material, available outer rotating edge impact,
Add the application function of hoe.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.
Following example are used for illustrating this utility model, but can not be used for limiting protection domain of the present utility model.Implement
Condition in example further can be adjusted according to actual conditions, and unaccounted condition is the condition in normal experiment.
Embodiment 1 hoe
Seeing accompanying drawing 1-2, described hoe uses manganese alloy hot strip steel to make, and is made up of hoe plate 1 and handle trousers 3, uproots plate 1
Making of a piece of manganese alloy hot strip steel with handle trousers 3, be structure as a whole, the middle and upper part, the back side of hoe plate is pressed with up big and down small " V "
The groove 2 of word vertebra shape structure, corresponding with groove 2, form protruding 5 in the front of hoe plate 1, described groove 2, protruding 5 upper end with
Handle trousers 3 are integrated.Handle trousers 3 are circular ring structure, the turned-out expansion of outer rim of handle trousers 3, form flange.
The hoe plate 1 of the present embodiment is together with the long 315mm of handle trousers 3, the wide 180-300mm of hoe plate 1.
The Hot drawing technique of embodiment 2 new hoe handle trousers
The equipment that the present embodiment production method uses includes punch press, uncoiler, purl machine, plate shearing machine, abrasive machine, pressure
Machine, heating furnace, the method use manganese alloy hot strip steel drawing and forming, production procedure be fracture punching put the first edge on a knife or a pair of scissors Logo pressure
Print workpiece heat handle trousers drawing and forming punching trousers deepening molding hardened face pre-treatment is coated with packing
Warehouse-in.
Concrete operation step:
1, fracture: by hot rolling 50mn belt steel material, be arranged on uncoiler, after purl machine is smoothed, cuts with plate shearing machine
Disconnected, disconnected size 530mm of material；
2, punching: see accompanying drawing 3, uses 160T punch press by disconnected for the material cut off, and punching is molding required form, cuts off shape；
3, put the first edge on a knife or a pair of scissors: using 300 abrasive machines, barreling hoe cutting edge position, and reach demand data, technical size is 20*
1.5mm；
4, Logo impressing: mark Logo by design shape, uses material high-speed steel or chromium steel, uses the pressure more than or equal to 35T
Power machine, suppresses the marking to the matrix of instrument brand；
5, workpiece heat: use roller hearth furnace heating, from pendulum to heating, uses heated by natural gas mode, to workpiece
It is heated to 850-950 DEG C；
6, handle trousers drawing: see accompanying drawing 4, utilizes two 35T forcing presses, is undertaken in two steps, and draws workpiece handle trousers position
Deep processing.
The first step is to work pieces process, and diameter dimension is 70-80mm, degree of depth 15-20mm, uses plain base drawing such as Fig. 4
4-A；
Second step carries out a diameter of 35-45mm to workpiece on the basis of first step workpiece, degree of depth 15-20mm dome-shaped draws
Deep such as the 4-B of Fig. 4；
7, molding: see accompanying drawing 5, uses composite die, utilizes 80-100T friction press, repair workpiece trousers position
Straightening footpath 48mm, the trousers portion of degree of depth 37mm, reach diameter 48mm in data size, lower diameter 42mm, the deep 37mm of trousers, and enter simultaneously
Row outward appearance molding is suppressed；
8, punching: as shown in accompanying drawing 6, by the data designed in advance, is punched out bottom trousers with 50-60T forcing press
6, punching 6 diameter dimension ￠ 25-30mm, single hole stamping-out, does basis preparation deeply for next step drawing；
9, trousers deepening molding: see that utilization shown in accompanying drawing 7 is deeply prolonged punch die and is processed workpiece, press tonnage 40T.
This work step determines handle trousers portion punch size, and punch size technical data is: major diameter 48mm, minor diameter 42mm, hole depth 47mm；
