Abstract
The utility model discloses a mechanism is sheared in embracing of bar cutter, characterized in that: the device comprises a die, wherein a bar material perforation in the front-back direction is arranged on the die, a semicircular shearing knife and a semicircular holding block are arranged in the front side direction of the die, the semicircular shearing knife is positioned right above the semicircular holding block, the semicircular shearing knife is pushed by a main oil cylinder to move up and down, the semicircular holding block is connected with an auxiliary cylinder, and the semicircular holding block is provided with a semicircular holding surface corresponding to the shearing semicircle of the semicircular shearing knife; when the shearing machine works, the semicircular shearing knife and the semicircular clamping block clamp the bar tightly and then shear and cut off the bar. The utility model discloses can reduce the shearing force to make the bar cut off the tip and level more.
Description
Technical Field
The utility model relates to a bar cutter that is used for bar to cut off, concretely relates to embracing of bar cutter is sheared mechanism.
Background
The long bar stock needs to be cut off by fixed-length shearing, and can be conveniently applied to subsequent industrial processing production. At present, a hydraulic power shearing machine is often used for shearing and cutting off a bar stock, and the action process is as follows: firstly, a heated bar extends out of a bar perforation of a die by a certain length, then a semicircular shearing knife is pushed by a hydraulic oil cylinder to quickly move downwards, and the bar extending out of the bar perforation is sheared and cut by a fixed length. In order to reduce the deformation of the end part of the bar stock when the bar stock is cut, the bar stock is generally heated to about 700 ℃, and if the heating temperature is too high, although the shearing force is small, the cut end part of the bar stock can generate large deformation. Due to the fact that the shearing force needs to be large, the cut ends of the bars are prone to deform and cause unevenness, and the bars with uneven ends cause large waste in subsequent industrial processing production.
Disclosure of Invention
In view of the deficiencies of the prior art, the to-be-solved technical problem of the present invention is to provide a shearing mechanism for rod shears capable of reducing shearing force and cutting off more smooth ends of the rod.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
the encircling shearing mechanism of the bar shearing machine is characterized in that: the device comprises a die, wherein a bar material perforation in the front-back direction is arranged on the die, a semicircular shearing knife and a semicircular holding block are arranged in the front side direction of the die, the semicircular shearing knife is positioned right above the semicircular holding block, the semicircular shearing knife is pushed by a main oil cylinder to move up and down, the semicircular holding block is connected with an auxiliary cylinder, and the semicircular holding block is provided with a semicircular holding surface corresponding to the shearing semicircle of the semicircular shearing knife; when the shearing machine works, the semicircular shearing knife and the semicircular clamping block clamp the bar tightly and then shear and cut off the bar.
A material blocking rod is arranged right ahead of the die, the material blocking rod makes elastic stretching movement in the front-back direction, and a rod material in-place detection switch detects the position condition of the material blocking rod.
After the technical scheme is adopted, the utility model discloses a working process is: the feeding mechanism pushes the bar stock forwards (the bar stock can be heated to the temperature required by forging, such as 1200 ℃), the front end of the bar stock is pressed against the stop bar through the bar stock through hole of the die, when the length of the bar extending out of the bar perforation reaches a set value, the feeding mechanism stops feeding the bar, at the moment, the main oil cylinder pushes the slide block and the semicircular shearing knife connected to the bottom of the slide block to quickly move downwards (at the moment, the push rod of the auxiliary cylinder is ejected outwards, the semicircular center of the semicircular holding block and the bar punching center of the die are in equal height and aligned state), when the semicircular shearing knife is close to the semicircular clamping block, the semicircular clamping surface arranged on the semicircular clamping block and the shearing semicircle arranged on the semicircular shearing knife clamp the bar tightly together, and then releasing an energy accumulator of the hydraulic system, pushing the semicircular shearing knife, the semicircular holding block and the tightly held bar downwards by the main oil cylinder, and shearing and cutting off the bar by the semicircular shearing knife. Foretell shearing cutting process, the bar is direct to be heated to very high temperature, and the shearing force can be less, simultaneously because the bar tip has semicircle shearing knife and semicircle to embrace the piece all the time and embraces the bar and hug closely when being cut off, so can make the cutting off tip of bar warp little, more level and more smooth.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figures, the utility model discloses a bar shearing machine's armful shearing mechanism, including mould 6, mould 6 sets up the bar perforation 5 of fore-and-aft direction, the front side direction of mould 6 is equipped with semicircle shearing sword 4 and semicircle and embraces tight piece 7, semicircle shearing sword 4 is located semicircle and embraces tight piece 7 directly over, semicircle shearing sword 4 is promoted by master cylinder 1 and is carried out the activity from top to bottom, semicircle shearing sword 4 is connected in the bottom of slider 2, slider 2 is connected with master cylinder 1, semicircle armful piece 7 is connected with supplementary jar 3, semicircle armful piece 7 is equipped with semicircle armful face 71 and corresponds with the shearing semicircle 41 of semicircle shearing sword 4, be used for embracing tightly embracing the bar that passes through, during shearing work, semicircle shearing sword 4 and semicircle armful tight piece 7 carry out shearing cutting to the bar after embracing tightly embracing the bar; the dead ahead of mould is equipped with dam device 8, and dam device 8 includes the striker rod, and the elastic stretching activity of fore-and-aft direction is made to the striker rod, has the position condition that bar target in place detection switch detected the striker rod.
