Abstract
The forging fixture of the utility model includes collet, rope, buffer unit, clamping device；Collet is cuboid and center is threaded hole, collet is also machined with the hole that several groups intersect vertically, rope is wound the chain to form several equal lengths in hole, rope after winding is connected with buffer unit, clamping device is symmetrical parts, and one end is machined with external screw thread and is connect with collet threaded hole.The utility model, which is equivalent to, repeatedly ties up gripped object with rope, rope and buffer unit can effectively reduce folded object and encounter influence of the impact force generated when impact to clamping device, increase the stability of mechanism, reduce damage of the collet to gripped object simultaneously, when clamping device unstability, sample will not be flown out by impact.
Description
Technical field
The utility model belongs to machinery field, and in particular to a kind of forging fixture.
Background technology
Conventional extruded forging fixture is substantially rigid contact with gripped object at present, when impact force is larger, to connecting machine
Structure and clamping mechanism will produce abrasion and loosening, influence service life and the safety of forging fixture, while can be to gripped object
Cause certain damage.
Utility model content
The shortcomings that the utility model is directed in the prior art provides one kind and has a safety feature, reduces and damaged to gripped object
Fixture.
The utility model adopts the following technical scheme that：
A kind of forging fixture, which is characterized in that the fixture includes collet, rope, buffer unit, clamping device；It is described
Collet is cuboid and center is threaded hole, and the screw thread hole depth is the half of the collet width, the folder
Head is machined with the hole that several groups intersect vertically, and the described one end of collet far from the threaded hole is machined with groove body；The rope
It is wound in the hole of the collet, forms the chain of several equal lengths, the rope after winding and the buffering
Device is connected；The clamping device is symmetrical parts, and the symmetrical parts are fixed by screw bolt and nut, and the clamping device leans on
One end of nearly screw bolt and nut is machined with external screw thread and is connect with the threaded hole.
According to above-mentioned fixture, which is characterized in that the buffer unit includes screw rod, nut and spring, and spring one end leans on
Nut, the other end on nearly screw rod are fixed together with the collet, and the screw rod and spring of the buffer unit are located at the folder
In head.
According to above-mentioned fixture, which is characterized in that the rope is hawser rope or thin cord.
According to above-mentioned fixture, which is characterized in that spring is helical spring, flat spring or piece bullet in the buffer unit
Spring.
According to above-mentioned fixture, which is characterized in that the clamping device type of drive is mechanical or hand.
The beneficial effects of the utility model：The utility model can keep the stability of clamping device, to a certain extent
Ensure that gripped object is not damaged by collet；Since rope is bound, workpiece is by clashing or when shock loading, generation is rushed
Hit load to be consumed by rope and buffer unit, be not transferred on hand or other force mechanisms, at the same rope be equivalent to it is multi-direction
Fixed, once unstability, gripped object will not be flown out due to the effect of rope, therefore have very high safety；In addition, can root
The quantity that lash rope is determined according to the size of gripped object has flexibility to a certain extent than rigid forging fixture.

Fig. 4 is the clamping device structural schematic diagram of the utility model.
Specific implementation mode
Referring to Fig. 1, the forging fixture of the utility model includes collet 1, rope 4, buffer unit 2, clamping device 3.
Referring to Fig. 2, collet 1 is cuboid and center is threaded hole, and screw thread hole depth is the one of 1 width of collet
Half, while collet 1 is machined with the hole that several groups intersect vertically, the one end of collet 1 far from threaded hole is machined with groove body.
Referring to Fig. 3, buffer unit 2 includes screw rod, nut and spring, nut of the spring one end on screw rod, the other end
It is fixed together with the collet, the screw rod and spring of buffer unit 2 are located in collet 1, and spring is spiral bullet in buffer unit
Spring, flat spring or flat spring；Rope is wound in the hole of collet 1, forms the chain of several equal lengths, winding
Rope afterwards is connected with buffer unit 2, and rope is according to gripped object weight selection hawser rope or thin cord.
Referring to Fig. 4, clamping device 3 is symmetrical parts, and symmetrical parts are fixed by screw bolt and nut, and clamping device 3 is close
One end of screw bolt and nut is machined with external screw thread and is connect with the threaded hole of collet 1, and the type of drive of clamping device 3 is mechanical
Or hand.
The production method of the forging fixture of the utility model includes the following steps：（1）Collet 1 is made, by 1 one end mill of collet
Slot, other end thread mill drilling, and collet 1 also process several groups of holes to intersect vertically；（2）Clamping device 3 is made, one end adds
Collet 1 and clamping device 3 are connected through a screw thread by work screw thread；（3）Buffer unit 2 is made, buffer unit 2 is mounted on collet 1
It is interior；（4）Rope is wound in the hole of collet 1, formed several equal lengths chain, and by after winding rope with
Buffer unit 2 in collet 1 is connected.
Gripped object is entangled with the forging fixture of the utility model using preceding, clamping forging fixture can be by gripped object
It tightens.
The utility model can keep the stability of clamping device, ensure that gripped object is not damaged by collet to a certain extent
Wound；Workpiece has very high safety by clashing or when shock loading is not transferred on hand or other force mechanisms
Property.
Forging fixture disclosed by the utility model and preparation method thereof, it is new that those of ordinary skill in the art can use for reference this practicality
Type content is realized by suitably changing the links such as forging fixture manufacture craft, punch position.The product and method of the utility model
It is described by preferred embodiment, related technical personnel can obviously not depart from the utility model content, spirit and model
Enclose it is interior method described herein and product are modified or are suitably changed combination, to realize the utility model technology.Especially need
It is noted that all similar replacements and change be for those of ordinary skills it will be apparent that they all
It is deemed to be included in the spirit of the present invention, range and content.
