Abstract
The utility model relates to a hammer, in particular to a farm hammer, which comprises a motor, a belt wheel connected with the motor, a flywheel driven by the belt wheel, a small belt wheel on the flywheel shaft, a bridge-crossing belt wheel on a eccentric shaft driven by the small belt wheel, an eccentric wheel on the eccentric shaft, a connecting rod connected with the eccentric wheel, spring steel plate connected with the connecting rod, a hammer connecting rod, hammer body, a hammer head, a hammer block under the hammer head, a hammer block jacket, an operation rod, and an operation spreading wheel connected with the other end of the spring steel plate, a hammer column connected with the center of the spring steel plate and a bottom seat. Compared with the air hammer, the farm hammer is simple in structure, low in processing cost, and can greatly reduce the heavy manual labor for the blacksmiths, who undertake the farm tools production in the remote regions.
Description
Affiliated technical field
The utility model relates to a kind of tool hammer, especially relates to a kind of agricultural tools hammer.
Background technology
At present, in the set hammer commonly used, the use of pneumatic hammer comparatively side is general, and it is by support, motor, and transmission mechanism, cylinder body, as the joining hammer cylinder of fuel tank, oil pump and control valve, the cylinder body of hydraulic mechanism, the hammering base is formed.The hydraulic oil that oil pump outpours during use injects cylinder body, and the effect of control valve pumps the hammer cylinder, constantly the hammering workpiece.The using of pneumatic hammer freed heavy manual labor of hanging down as forger and played positive effect, but the volume of pneumatic hammer is big, and be heavy, cost is high, power consumption is big, and processing cost height in small-sized furniture processing can't be popularized in vast rural area outlying mountain area.Granted publication number has proposed a kind of spring set hammer of suitable small workpiece forging and pressing for the utility model patent of CN2408991Y, and it is made up of frame, motor, drive pulley, negative pulley wheel, crankshaft rod assembly, the hammering base that is positioned at hammering parts bottom; The connection of slide block and hammering parts is the fixed connection of damping Luo bar assembly by tommyhead bolt and slide block; Structure is more simpler than pneumatic hammer, and cost further reduces.Yet because this designs distinctive damping device and hammer body connects very in succession, with impact velocity running hours faster, its damping device very easily damages, in the rural area and outlying district easy-maintaining not.
Summary of the invention
For overcome existing agricultural tools hammer out this height, complex structure, so that the impact velocity running hours is fragile faster, the shortcoming that can't popularize in vast rural area outlying mountain area, the utility model provides a kind of agricultural tools simple in structure hammer, this hammer only needs 220 volts, 1.5-2.2 kilowatt monophase machine, can drive the tup of 60-65 kilogram weight, can be with the impact velocity continuous operation of per minute 208 times, can alleviate heavy manual labor greatly for the forger that outlying mountain area is engaged in farm implements production.
Gap bridge belt pulley on the flywheel that the utility model agricultural tools hammer drives by motor, the belt pulley that links to each other with motor, by belt pulley, the small belt pulley on the flywheel shaft, the eccentric shaft that drives by small belt pulley, the eccentric wheel on the eccentric shaft, the connecting rod that is connected with eccentric wheel, be connected with connecting rod steel spring plate, the tup connecting rod that is connected with the steel spring plate other end, hammer body, tup, reach hammer anvil below the tup, hammer anvil guard shield, action bars, operation regulating wheel, with the middle hammer post that is connected of steel spring plate, base composition.
The principal character of the utility model agricultural tools hammer is that its damping device adopts automobile spring plate to connect for passing a bridge.
It is as follows that the designed agricultural tools of the utility model is hammered its operation principle into shape: behind the starter motor, drive flywheel by motor pulley, by the idler on the drive of the small belt pulley on the flywheel shaft eccentric shaft, reciprocating by the moving connecting rod of generation of the eccentric wheel on the eccentric shaft again, because connecting rod links to each other with an end of steel spring plate, and the other end of steel plate links to each other with the tup connecting rod, thereby tup connecting rod traction hammer body is moved up and down along the tup track, eccentric wheel rotates soon more, the compression number of times of steel plate is many more, and that tup impacts on workpiece is frequent more.The impulsive force of this hammer depends on the weight of tup and the elasticity of steel plate, if the workpiece of machining large can increase the weight of the elasticity of bell head and reinforcement steel plate as required.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a right view of the present utility model.
1. motor among the figure, 2, motor pulley, 3, flywheel, 4, the small belt pulley on the flywheel shaft, 5, the gap bridge belt pulley on the eccentric shaft, 6, eccentric wheel, 7, connecting rod, 8, steel spring plate, 9, tup connecting rod, 10, hammer body, 11, the tup track, 12, tup, 13, lower ram, 14, hammer anvil, 15, the hammer anvil guard shield, 16, action bars, 17, operation regulating wheel, 18, pillar, 19, base, 20, spring buckle, 21, the transmission case guard shield, 22, motor cabinet
In Fig. 1, behind the starter motor 1, drive flywheel 3 by motor pulley 2, by the idler 5 on the 4 drive eccentric shafts of the small belt pulley on the flywheel shaft, reciprocating by 6 drivening rods 7 of the eccentric wheel on the eccentric shaft again, because connecting rod 7 links to each other with an end of steel spring plate 8, and the other end of steel spring plate 8 links to each other with tup connecting rod 9, thereby tup connecting rod 9 traction hammer bodies 10 are moved up and down along tup track 11, eccentric wheel 6 rotates soon more, the compression number of times of steel plate is many more, and that tup impacts on workpiece is frequent more.The impulsive force of this hammer depends on the weight of tup 12 and the elasticity of steel spring plate, if the workpiece of machining large can increase the weight of the elasticity of bell head 12 and reinforcement steel plate 12 as required.
Claims (2)
1. an agricultural tools is hammered into shape, this tool hammer is by motor, the belt pulley that links to each other with motor, flywheel, flywheel shaft, eccentric wheel, the connecting rod that is connected with eccentric wheel, the damping elastic device that is connected with connecting rod, the tup connecting rod that is connected with the damping elastic device other end, hammer body, tup, and the hammer anvil of tup below, the hammer anvil guard shield, action bars, pillar, base is formed, it is characterized in that this damping elastic device is for adopting spring steel plate, the connecting rod that one end of spring steel plate is connected with eccentric wheel is connected, the other end is connected with the hammer body connecting rod, and the centre of spring steel plate is connected with post top portion.
