Fine adjustment formula fuse machine pressure heads mechanism
Technical field
The utility model relates to pneumatic equipment, relates in particular to the joint mechanism of applying in pneumatic equipment.The utility model relates to fuse machine technical field, more particularly, and particularly a kind of fine adjustment formula fuse machine pressure heads mechanism.
Background technology
In a lot of manufacturing equipments, in fuse machine, be generally all provided with hold-down devices (being pressure head structure), it needs the product of processing and manufacturing for hot pressing, and in processing and manufacturing process, need to carry out the degree of depth and pressure adjusting accurately to the point of crimping.
As shown in Figure 1, in prior art, pressure head structure generally comprises the adjustable pressure head cylinder 1' of stroke, the guide rod 2' that is positioned at both sides and pressure head 3', in use, is that the downforce band dynamic head 3' of the pressure head cylinder 1' adjustable by stroke is to realize crimping.But, because pressure in pressure head structure of the prior art regulates, be that down force pressure by regulating pressure head cylinder 1' realizes, when the very little pressure of needs, only by regulating the down force pressure of pressure head cylinder 1' to be difficult to reach the degree of depth and pressure accurately, regulate.
Utility model content
The utility model provides fine adjustment formula fuse machine pressure heads mechanism, is intended to solve in prior art only by the down force pressure that regulates pressure head cylinder, be difficult to reach the degree of depth and pressure controlled technical problem accurately.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of fine adjustment formula fuse machine pressure heads mechanism, comprise pressure head cylinder, the pressure head being connected with pressure head cylinder, with the guider for pressure head cylinder is led, described pressure head cylinder top is provided with and can accurately regulates pressure head to press down the buffer regulating device of the degree of depth and pressure.
Buffer regulating device described in the utility model comprises bounce cylinder, buffer stopper and the adjustable connecting plate that can adjust up and down, described bounce cylinder is installed on pressure head cylinder top, buffer stopper is located at bounce cylinder top, described guider comprises two guide rods that are positioned at pressure head cylinder both sides, described adjustable connecting plate is connected between the top of two guide rods, and described buffer stopper is positioned at the below of adjustable connecting plate.
The tailpiece of the piston rod of bounce cylinder described in the utility model arranges upward, and described buffer stopper is located at the top of this piston rod.Buffer stopper can avoid adjustable connecting plate when contacting, can not produce too large strike note with bounce cylinder.
Between guide rod described in the utility model and adjustable connecting plate, adopt clamp structure fastening.Simple in structure, easy for installation, processing cost is low, and mechanical strength is good.
Guide rod described in the utility model adopts the high accuracy axis of guide, thus the accurate location that can obtain pressing down.
Pressure head cylinder described in the utility model is the uncontrollable pressure head cylinder of stroke.
The beneficial effects of the utility model are:
Fine adjustment formula fuse machine pressure heads mechanism of the present utility model, pressure head cylinder adopts the non-adjustable cylinder of stroke, and increased bounce cylinder, pressure head cylinder can be with dynamic head fast approaching product, and do time delay buffering by buffer regulating device, and compensator or trimmer pressure becomes adjustable, by adjusting the position of adjustable connecting plate on guide rod, just can adjust the falling-threshold height of pressure head, and then realize the pressure head degree of depth and pressure adjusting accurately.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with concrete accompanying drawing, realization of the present utility model is described in detail.
Specific embodiment of the utility model as shown in Figure 2, a kind of fine adjustment formula fuse machine pressure heads mechanism, comprise pressure head cylinder 1, the pressure head 3 being connected with pressure head cylinder 1, with the guider for pressure head cylinder 1 is led, pressure head cylinder 1 top is provided with and can accurately regulates pressure head to press down the buffer regulating device of the degree of depth and pressure.
In the present embodiment, buffer regulating device comprises bounce cylinder 4, buffer stopper 5 and the adjustable connecting plate 6 that can adjust up and down, bounce cylinder 4 is installed on pressure head cylinder 1 top, buffer stopper 5 is located at bounce cylinder 4 tops, guider comprises two guide rods 2 that are positioned at pressure head cylinder 1 both sides, described adjustable connecting plate 6 is connected between the top of two guide rods 2, and buffer stopper 5 is positioned at the below of adjustable connecting plate 6.The tailpiece of the piston rod of bounce cylinder 4 arranges upward, and buffer stopper 5 is located at the top of this piston rod.Buffer stopper 5 plays the effect of the piston rod of protection bounce cylinder 4.Between guide rod 2 and adjustable connecting plate 6, adopt clamp structure fastening.Guide rod 2 adopts the high accuracy axis of guide.Pressure head cylinder 1 is the uncontrollable pressure head cylinder of stroke.
Above-mentioned buffer stopper 5 can select to match steel uniform wearability part.
The course of work of the present utility model is as follows:
1, bounce cylinder 4 is for stretching out position;
2, pressure head cylinder 1 presses down fast, and adjustable connecting plate 6 moves down along guide rod 2, and buffer stopper 5 withstands adjustable connecting plate 6, makes pressure head 3 stop pressing down approaching product space;
3, through time delay, the piston rod of bounce cylinder 4 is regained, and pressure head 3 continues to press down, and with product laminating, carries out hot-pressing processing.
The above embodiments are only preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations of doing according to the utility model claim, still belongs to the scope that the utility model is contained.
