Abstract

The utility model relates to a spring type forging pressing hammer, which is composed of a machine frame, a motor, a drive belt pulley, a driven belt pulley, a crankshaft connecting rod mechanism, a bearing, a seat, a sliding guide groove, a sliding block, a cushioning screw rod assembly which is used as a hammering component part, and a base which is arranged on the upper part of the hammering component part. The connection of the sliding block and the hammering component part is the fixed connection of the cushioning screw rod assembly and the sliding block by a T-shaped screw bolt. The spring type forging pressing hammer has the advantages of simple structure and low cost. Compared with pneumatic hammers of the same kind, the electricity consumption is reduced by 75 percent. The spring type forging pressing hammer is suitable for processing small forging pieces.

Description

The spring set hammer

The utility model relates to a kind of set hammer.

In set hammer, the use of pneumatic hammer is more extensive; 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; During use, the hydraulic oil that oil pump outpours 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, can not bring into play its due effect in small-sized farm implements processing.

The purpose of this utility model is: design a kind of spring set hammer.

Feature of the present utility model is: its hammering parts are that damping screw rod assembly reaches and the joining hammer cylinder of damping screw rod assembly, and damping screw rod assembly is fixedly connected by tommyhead bolt and slide block.

Because adopt technique scheme, the utility model is compared with similar pneumatic hammer, power consumption reduces by 75%, and cost is low, and is simple in structure, easy to maintenance, is suitable for the processing of small farm machine.

Below in conjunction with the embodiment accompanying drawing the utility model structure is described in further detail.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model left view;

Fig. 3 is a damping screw rod assembly structure chart;

Fig. 4 connects figure for damping spiral shell village assembly with the hammer cylinder;

Fig. 5 is the tommyhead bolt structure chart.

In conjunction with Fig. 1, Fig. 2, the spring set hammer, it is by frame 8, be fixedly mounted on the motor 2 of frame 8 one sides, be installed in the drive pulley 1 on the motor 2, be fixedly mounted on the crankshaft connecting rod system 5 on frame 8 tops by bearing and seat 4, be fixedly mounted on drive pulley 1 a corresponding side crankshaft connecting rod system 5 on negative pulley wheel 3, be fixedly mounted on the sliding guide groove 7 on the frame 8, be installed in the sliding guide groove 7 and with crankshaft connecting rod system 5 joining slide blocks 6, damping screw rod assembly 10 and hammer cylinder 12 as the hammering parts, the hammering base 13 that is in hammering parts bottom is formed; Damping screw rod assembly 10 links (with reference to Fig. 4) with hammer cylinder 12, and damping screw rod assembly 10 is fixedly connected by tommyhead bolt 9 (with reference to Fig. 5) and slide block 6.For keeping hammer cylinder 12 to make rectilinear motion up and down reciprocatingly, hammer cylinder 12 is with guide thimble 11, and guide thimble 11 is fixedly connected with frame 8, and realization hammer cylinder 12 connects with frame 8.

In conjunction with Fig. 3, damping screw rod assembly 10 is made of U bolt 14, spring 17, upper spring pressing plate 15 and lower spring pressing plate 16, and spring 17 is fixed between the upper and lower

spring bearer plate

15,16 by nut 18; The connection (with reference to Fig. 4) of damping screw rod assembly 10 and hammer cylinder 12 is to pass the slotted hole that hammer cylinder 12 is provided with by upper and lower

spring bearer plate

15,16 to realize.

When using the utility model (with reference to Fig. 1), motor 2 startings, the motion of crankshaft connecting rod system 5 drive as the damping screw rod assembly 10 of hammering parts and hammer cylinder 12 and do upper and lower reciprocating motion, the hammering forging.
