Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention. In addition, all the connection relations mentioned herein do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Referring to fig. 1 to 5, this is an embodiment of the invention, specifically:

a guide mechanism of an arc edge-fastening machine, which comprises a machine body and a guide component, wherein the machine body is provided with a working wheel 21, the guide assembly comprises a guide block 31, the guide block 31 is arranged at the right side of the working wheel 21, the bottom of the guide block 31 is provided with a guide surface, a section line formed by sectioning the guide surface along the front-back direction comprises a first straight line section and a second curve section, the first straight line segment is connected with the second curved line segment in a fillet mode, the first straight line segment is swept into a first guide circular arc surface 311, the second curve segment is swept into a second guiding curved surface 312, the first guiding arc surface 311 and the second guiding curved surface 312 are connected by a circular angle surface, the first guiding arc surface 311 gradually extends downwards from right to left, the second guiding curved surface 312 gradually extends downwards from right to left, and the second guiding curved surface 312 gradually extends downwards from front to back.

When the spiral case guiding device is used, the first guiding arc surface 311 is used for being abutted against the upper wall of a spiral case product, the upper part of the second guiding curved surface 312 is used for being abutted against the side wall or the corner of the spiral case product, and a gap is reserved between the lower part of the second guiding curved surface 312 and the spiral case product. The pre-compaction wheel that is the cone among the prior art only with the upper wall butt of product, and the area of contact between guide block 31 in this application and the product is big, plays the effect of gradual change pre-compaction, can also play the effect of direction simultaneously.

The inventor tries to modify the conical pre-pressing wheel to realize the edge buckling of the arc-shaped pipeline, but in the actual use process, the contact area between the conical pre-pressing wheel and the vertical metal sheet body is very small, the pressure intensity is very large, and the metal has elasticity, so that in the edge buckling process, the situation of jumping often occurs, the edge of the vertical metal sheet body forms a wavy shape, and the jumping is more obvious when the pipeline works on the arc-shaped pipeline with smaller curvature. The assumption is that the circular cone-shaped prepressing wheel is used for processing arc-shaped pipeline products, and originally, the vertical metal sheet body is easily extruded with creases in the process of bending downwards, so that the production is not realized.

Regarding the guiding action of the guide block 31: because the right-hand member of first direction arc surface 311 is located the top of the left end of first direction arc surface 311, the structure of this application moves from a left side right side on the arc pipeline and detains the limit during operation, and guide block 31 can move on the product smoothly, and the right side from first direction arc surface 311 that the product can be smooth is leading-in the below of guide block 31 for the structure of this application is applicable to and processes the arc pipeline.

Regarding the preload action of the guide block 31: the contact range of the first guide arc surface 311 and the volute product can be adjusted by adjusting the diameter of the first guide arc surface, the larger the diameter is, the closer the first guide arc surface is to the plane, the larger the contact range of the first guide arc surface and the product is, and the better the pre-pressing effect is. And when the product is deformed, the product is deformed downwards gradually from right to left following the shapes of the first guiding arc surface 311 and the second guiding curved surface 312, and the product is also extended downwards gradually from front to back following the shape of the second guiding curved surface 312, so that the shape mutation of the product is avoided, the internal stress in the product is reduced, and the pre-pressing effect is good.

In some embodiments, the axis of the first guiding arc surface 311 is arranged in the front-back direction. Then, after the pre-compaction of the first guiding arc surface 311, the edge of the product sheet extends forwards horizontally and is consistent with the direction of the final pressing of the sheet edge by the working wheel 21, along with the rightward pushing of the guiding block 31, the edge of the product sheet moves from back to front and moves from top to bottom, and finally the movement from back to front is consistent with the pre-compaction direction of the first guiding arc surface 311, so that the pre-compaction process has a very good effect on reducing stress.

In some embodiments, the second curved line segment is an arc line segment or a hyperbolic line segment, an axis of the second guiding curved surface 312 is arranged in a front-back direction, and the second curved line segment rotates around the axis to sweep into the second guiding curved surface 312. So, each part camber is the same or gradual change on the second direction curved surface 312, and is even or the even change to the pre-compaction effort of spiral case product, all above prevent to produce bad deformation on the original vertical sheet metal body on the arc pipeline easily, improve the technical scheme who detains the limit quality.

In some embodiments, a vertical first mounting surface 11 and a horizontal first sub-mounting surface 12 are provided at the front portion of the body, the rear side surface of the guide block 31 is a plane, the rear side surface of the guide block 31 abuts against the first mounting surface 11, and the upper side surface of the guide block 31 abuts against the first sub-mounting surface 12. The pre-compaction wheel among the prior art is connected with the fuselage through the pivot, because the connection between pivot and the fuselage is unstable, the during operation produces mutual vibrations easily between cone and the fuselage, and the difficult fuselage that lives of staff uses comparatively difficultly to the cone is very little with the area of contact between the product of being detained the limit, and the direction effect is not good. The rear side surface of the guide block 31 is abutted to the first mounting surface 11, and the upper side surface of the guide block 31 is abutted to the first auxiliary mounting surface 12, so that the guide block 31 and the machine body can be prevented from generating relative vibration, and labor can be saved when a user uses the structure.

In some embodiments, a notch 313 is formed in a left portion of the guide block 31, the notch 313 intersects with both the first guiding arc surface 311 and the second guiding curved surface 312, and the working wheel 21 is disposed in the notch 313. The prepressing action of the guide block 31 and the pressing action of the working wheel 21 can be tightly connected, the product is continuously and gradually changed when being deformed, and the edge buckling efficiency is high.

Further, a bale returning part is arranged below the gap 313, the bale returning part and the guide block 31 are integrally formed, and the left end of the bale returning part extends to the position below the working wheel 21. This structure can further reduce the engagement distance between the guide block and the running wheel.

Optionally, the notch 313 is a cylindrical surface extending in the front-rear direction. Thus, the shape of the notch 313 is matched with that of the working wheel 21, the gap between the notch 313 and the working wheel 21 is uniform, and the connection time between the prepressing action and the pressing action of the working wheel 21 is reduced.

In some embodiments, the guiding assembly further comprises a guiding wheel 32 arranged on the body, an axis of the guiding wheel 32 is arranged along the vertical direction, and as the axis of the guiding wheel 32 is arranged along the vertical direction, during operation, the guiding wheel 32 rolls on the side wall of the volute, and the guiding wheel 32 and the guiding block 31 cooperate to tightly attach to both the upper wall and the side wall of the volute, so that smooth guiding is realized. Because the guide wheel 32 can roll on the volute, different from the sliding of the guide block 31 on the volute, the resistance of the rolling guide mode is smaller, and the guide wheel can not make the use of the integral arc edge buckling machine more laborious as auxiliary guide.

Further, the number of the guide wheels 32 is two, and the axes of the two guide wheels 32 coincide. So, two leading wheels 32 should be vertically arranged and set up, and two leading wheels 32 of vertical arrangement can prevent that the limit machine is detained to the arc limit from inclining from beginning to end, and the limit machine during operation is detained to the arc limit more stable.

In some embodiments, the vehicle body further comprises a stopper 25, wherein the stopper 25 comprises an upper body and a front body fixedly connected with the upper body, the front body is arranged in front of the working wheel 21, the front end of the upper body is fixedly connected with the front body, and the rear end of the upper body is fixedly connected with the vehicle body. When the hand-operated hand-held machine works, the working wheel 21 moves rightwards, a person holds the machine body to follow the working wheel 21 rightwards, the stop block 25 isolates the hand from the working wheel 21, and the safety of the hand is protected.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions, all of which are within the scope of the claims appended hereto.
