Fig. 1 illustrates a schematic perspective view of a shearing mechanism of an automatic shearing and welding machine provided in the present application, wherein the automatic shearing and welding machine includes a housing 10, the housing 10 is provided with a shearing space 11, and fig. 2 is a schematic structural view of an inside of the shearing mechanism of the automatic shearing and welding machine, fig. 2 is a schematic structural view of the shearing mechanism of the automatic shearing and welding machine, wherein a pair of first shearing assembly 20 and a second shearing assembly 30 are oppositely disposed in the housing 10, in a transverse direction, and referring to a direction from left to right in fig. 2, the first shearing assembly 20 includes a first shearing part 21 and a first elastic pressing part 22 which are sequentially disposed, the second shearing assembly 30 includes a second elastic pressing part 31 and a second shearing part 32 which are sequentially disposed, the first shearing part 21 corresponds to the second elastic pressing part 31, the first elastic pressing part 22 corresponds to the second shearing part 32, the pair of shearing assemblies are respectively located at upper and lower sides of the shearing space 11, of course, the upper and lower positional relationship of the first cutting assembly 20 and the second cutting assembly 30 can be reversed and are within the scope of the present application.

With reference to fig. 2, the first shearing part 21 is fixedly mounted on the housing 10, the fixing manner may be bolt connection or adhesion, etc., the second shearing assembly 30 is connected to a driving part 40 capable of driving the second shearing assembly 30 to move up and down, the driving part 40 may be a driving device powered by hydraulic pressure or air pressure, and is used to drive the second shearing assembly 30 to move up or down, when the second shearing assembly 30 moves up, the second shearing part 32 and the first shearing part 21 may be sheared in a staggered manner, so that the steel strip may be directly sheared into two sections by shearing in a staggered manner, the steel strip may not produce leftovers during shearing, and the material is saved while the waste material is reduced. In a specific embodiment, see fig. 2 and 3 simultaneously, the second tool apron has a cutting portion 321, and the cutting surface on the upper side of the cutting portion 321 is inclined relative to the horizontal plane, so that the steel strip can be sequentially cut when being cut, and the cutting is faster and smoother, the cutting obstruction is small, and the steel strip can be smoothly cut without any noise.

It is particularly important that the automatic shear welder further comprises a guide member mounted to the housing 10, which may include a first guide member 51 and a second guide member 52, as seen in fig. 3 and 4, and the guide member has a guide rail 53 extending in a vertical direction, and the second shear member 32 is slidably coupled to the guide rail 53. Since the guide member is mounted on the housing 10, the guide member has a fixed position relative to the housing 10, and further, when the second cutting member 32 moves along the guide track 53 of the guide member, the second cutting member has a relatively stable moving track, so that the same moving track is maintained during multiple reciprocating cutting processes of the second cutting member, and a stable effect of cutting the steel strip each time is ensured.

With continued reference to fig. 3 or 4, in the extending direction (left-right direction in fig. 3 or 4) of the cut portion 321 on the second cutting member 32, the first guide 51 and the second guide 52 are respectively provided on both sides of the second cutting member 32.

First, in the specific embodiment as shown in fig. 4, the cutting part 321 is disposed obliquely, the right side of the cutting part 321 is higher than the left side, during cutting, the second guide 52 located at the right side of the second cutting member 32 guides the right side of the cutting part 321 to be accurately staggered with the first cutting member 21 first, cutting between the second cutting member 32 and the first cutting member 31 can be accurately performed by performing stable guide at the higher side of the cutting part 321, then as the second cutting member 32 continues to move upwards, the first guide 51 at the left side of the second cutting member 32 gradually guides the cutting part 321 to complete the staggered cutting process with the first cutting member 21, and staggered cutting can be more stably completed by performing stable guide at the lower side of the cutting part 321.

Secondly, if the cutting portion 321 of the second shearing part 32 is rotationally deformed in the horizontal direction due to vibration or other factors, the second shearing part 32 is likely to collide with the first shearing part 31 when moving upwards, so that the second shearing part cannot be sheared in a staggered manner, and therefore the first guide part 51 and the second guide part 52 arranged on the two sides of the second shearing part 32 can play a role in preventing the second shearing part 32 from rotationally deforming, so that the second shearing part 32 can reduce or overcome negative effects such as rotation caused by the moving shearing of the second shearing part 32 in the moving process, and the moving shearing of the second shearing part 32 is more stable and accurate in multiple reciprocating processes.

In addition, providing the first guide 51 and the second guide 52 on both sides of the second cutting member 32 may make the installation of the guides with the second cutting member 32 easy. Specifically, the second guide 52 can be installed on the housing 10, the second cutting member 32 can be installed in cooperation with the guide rail 53 of the second guide 52, and finally the guide rail 53 of the first guide 51 can be installed on the housing in cooperation with the second cutting member 32, so that the installation and assembly are simple, and the parts such as the first guide 51, the second guide 52, the second cutting member 32 and the like can be easily observed and disassembled, therefore, the damaged parts can be easily disassembled and replaced after frequent use, and the maintenance is convenient. And the guide piece can be directly connected with the shell for installation, and in the embodiment described later, the guide piece can be conveniently adjusted by an operator.

When first shearing piece 21 and the relative crisscross shearing of second shearing piece 32, first elasticity compresses tightly piece 22 and can compresses tightly at the second shearing piece 32 of the last side direction of second shearing piece 32 to make the steel band can keep smooth shear plane when being sheared, and then can make the shearing of steel band more level and more smooth, and cut the whole deformation that can not warp of back steel band, still can keep original roughness, provide convenience for other processes such as subsequent welding.

Meanwhile, as the upward movement of the second shearing part 32 continues, the first elastic pressing part 22 may also be elastically deformed to give way to the second shearing part 32 while pressing the steel strip, so that the second shearing part 32 moves upward and shears the steel strip together with the first shearing part 21. Preferably, when the second shearing assembly 30 moves upwards, the second elastic pressing member 31 also moves upwards and presses the steel strip upwards together with the first shearing member 21, so that when the steel strip is sheared by the first shearing member 21 and the second shearing member 32, both sides of the sheared part are flattened by the elastic pressing members, shearing is more stable and faster, and the sheared steel strip can keep the flatness before shearing so as to be used in other operations after subsequent welding. Meanwhile, as the second shearing assembly 30 moves upward, the first shearing part 21 may elastically deform the second elastic pressing part 31 to give way to the first shearing part 21.

Through the setting of first shearing module 20 and second shearing module 30, both can keep the planarization of steel band when cuting the steel band, can make again to cut and become more stable fast, and can not produce the leftover bits and pieces, consequently the steel band cross-section of shearing department is more neat, and does not have the harm to steel band itself almost, cuts unimpeded without having an abnormal sound.

After the cutting is completed, the second cutting assembly 30 is moved downwards by the driving member 40, so that the first cutting assembly 20 is separated from the second cutting assembly 30, and the cut steel strip can be removed from the cutting space 11 to complete a cutting operation.

As to the fixing manner of the guide, in a specific embodiment, the guide is coupled with the housing 10 by a plurality of bolts, with continued reference to fig. 1, 3 or 4, the plurality of bolts includes at least one set bolt 61 and at least one adjustment bolt 62, the set bolt 61 is threaded onto the main plate 14 of the housing 10, referring to fig. 4, the end of the positioning bolt 61 abuts against the first guide 51, the head of the positioning bolt 61 abuts against the housing 10 outside the main board 14, the screw of the positioning bolt 61 is connected to the main board 14 by screw, the end of the screw abuts against the first guide 51 inside the main board 14, so as to act as abutting support for the first guide 51, so that the first guide 51 can be sufficiently contacted with the second cutting member 32 and maintain a certain pushing force, therefore, the first guiding element 51 provides a more accurate and stable guiding function for the second cutting element 32. The head of the adjusting bolt 62 is also outside the main plate 14, the screw of the adjusting bolt 62 is threaded to the first guide 51 after passing through the main plate 14, the first guide member 51 can be relatively moved closer to or away from the second cutting member 32 by turning the head of the adjusting bolt 62 through the screw thread of the screw, thereby achieving more precise adjustment of the first guide member 51, after the adjusting bolt 62 is adjusted in position, the head of the adjusting bolt 62 can be held by hand and a shear test can be performed, to detect whether stable guiding without large friction is achieved between the first guide 51 and the second shearing member 32, and to screw the positioning bolt 61 into abutment with the first guide 51, the set bolt 61 and the adjusting bolt 62 together fix the first guide 51 to the housing 10, so that the first guide member 51 has a fixed position with respect to the housing 10, thereby stably guiding the second cutting member 32. Moreover, the position of the first guide element 51 is made adjustable to a certain extent by the way of the adjusting bolt 62 and the positioning bolt 61, and the distance between the first guide element 51 and the second shearing element 32 can be adjusted as required, for example, when the guiding capacity of the second shearing element 32 is weakened due to the fact that the guiding track 53 of the first guide element 51 is worn, the first guide element 51 can be adjusted to move towards the direction close to the second shearing element 32 by the adjusting bolt 62 and the positioning bolt 61, so that the guide element can play a better precise guiding role for the second shearing element 32.

Furthermore, by providing the positioning bolt 61 and the adjusting bolt 62, the adjusting bolt 62 may have a tendency of pulling the first guide 51 toward the housing 10, the positioning bolt 61 may have a tendency of pushing the first guide 51 away from the housing 10, and the positioning bolt 61 and the adjusting bolt 62 may cooperate to limit the first guide 51 to a fixed position relative to the housing 10, in a preferred embodiment, referring to the embodiment shown in fig. 1 or fig. 3 and fig. 4, the plurality of bolts may include one positioning bolt 61 and a pair of adjusting bolts 62 symmetrically disposed on both sides of the positioning bolt 61, and since the first guide 51 extends in the vertical direction, the pair of adjusting bolts 62 may more accurately and stably position the first guide 51.

Of course, with continued reference to fig. 1, the positioning bolt 61 and the adjusting bolt 62 may be mounted on the main plate 14 of the housing 10, and may also be mounted on the side plate 15 of the housing 10. When a plurality of bolts are mounted to the main plate 14, the bolts can adjust the movement of the guide in the extending direction of the cutting portion 321 on the one hand, and can restrict the movement of the guide in the radial direction of the bolts; when the bolts are mounted on the side plate 15, the bolts can adjust the movement of the guide member in the transverse direction to adjust the shearing distance between the second shearing member 32 and the first shearing member 21, so that the staggered shearing effect is better, and the bolts on the side plate 15 can limit the guide member at a fixed position after adjusting the distance between the guide member and the side plate 15.

The plurality of bolts disposed on the main plate 14 or the side plate 15 may be different embodiments, which are respectively applied to an automatic welding and trimming machine. It will be appreciated that when the embodiment shown in fig. 1 is employed, the plurality of bolts located on the side plate 15 may simply be bolts that secure the guide, not functioning as the positioning bolts 61 and the adjustment bolts 62. Or, a plurality of adjusting bolts 62 and positioning bolts 61 are disposed on the main board 14 and the side board 15, wherein a hole for the adjusting bolt to pass through on the main board 14 extends in the transverse direction, and a hole for the adjusting bolt to pass through on the side board 15 extends in the extending direction of the cutting portion 321, so that after the bolt on the side board 15 adjusts the position of the guide piece in the transverse direction, the adjusting bolt 62 on the main board 14 can extend into the threaded hole of the guide piece to be adjusted, and after the adjustment is completed, the positioning and the fixing can be performed through the positioning bolts on the main board 14 and the side board 15.

While the first guide 51 is used as an example to show the connection relationship between the plurality of bolts and the guide, it is understood that the same trial for the second guide 52 regarding the connection relationship between the plurality of bolts and the guide is also included in the scope of protection of the present application.

In a preferred implementation manner of the automatic shearing and welding machine, the guide track 53 is a conical groove formed in the guide member, as shown in fig. 3 and 5, the second shearing part 32 has a conical protruding structure 322 matching with the conical groove, and the conical groove can completely limit the movement of the second shearing part 32 in the horizontal direction as much as possible by the guiding matching manner of the conical protruding structure 322 and the conical groove, so that the second shearing part 32 can move in a fixed vertical direction to complete more accurate shearing. And the conical groove is relative to the grooves with other shapes, so that the contact area between the guide piece and the second shearing piece 32 is relatively smaller, the friction force can be reduced to a certain extent, and the movement of the second shearing piece 32 is smoother.

The tapered groove is further optimized in that the guide track 53 is formed with an avoiding groove 54 at the end of the tapered groove, as shown in fig. 5, the tip of the tapered protruding structure 322 of the second cutting member 32 protrudes into the avoiding groove 54, the tip of the tapered protruding structure 322 and the tip of the tapered groove are easily interfered with each other, and even after the second cutting member 32 is slightly inclined, the tip of the tapered groove directly blocks the movement of the second cutting member 32, so that by providing the avoiding groove 54, the probability that the tapered groove blocks the second cutting member 32 can be reduced, and the second cutting member 32 can be moved and cut more easily and smoothly.

In a preferred implementation of the automatic welding machine, with continued reference to fig. 3, the cutting space 11 has a feed opening 12 at the first guide 51, the cutting portion 321 being inclined downwards in the direction towards the first guide 51, and the second guide 52 being higher than the first guide 51. Since the cutting portion 321 is disposed obliquely, the higher side of the cutting portion needs the higher second guide 52 for guiding, the automatic welding and shearing machine generally has the feeding hole 12, and the lower first guide 51 is disposed on the side of the feeding hole 12, so that feeding of the steel strip is not delayed, and long-distance guiding of upward movement of the second cutting member 32 is also satisfied, so that shearing is more stable.

In a preferred implementation manner of the automatic shearing and welding machine, the housing 10 is provided with an avoidance gap 13 on the side of the first elastic pressing piece 22 of the first shearing assembly 20, and the avoidance gap 13 is communicated with the shearing space 11. Referring to fig. 1 or fig. 3, in the embodiment of fig. 1 and fig. 3, the driving member 40 drives the second shearing assembly 30 to move upward, when the shearing end face of the first shearing member 21 is flush with the shearing end face of the second shearing member 32, the second shearing member 32 still needs to move upward to complete the complete shearing of the steel strip, if the avoidance notch 13 is not provided, the housing 10 is prone to block the steel strip when the second shearing member 32 continues to move upward, so as to bend the steel strip, which is not beneficial to smooth subsequent operations such as further welding of the steel strip shearing position. Therefore, by arranging the avoiding notch 13, the steel strip can enter the avoiding notch 13 when the second shearing part 32 continuously pushes the steel strip to move upwards, so that the original flatness of the steel strip can be kept, and the subsequent use is facilitated. It can be understood that, if the driving element 40 is disposed on the upper side of the first shearing assembly 20, and the first shearing part 21 of the first shearing assembly 20 moves downward to shear the steel strip, the avoidance gap 13 may be disposed on one side of the second elastic pressing part 31 of the second shearing assembly 30, as long as the avoidance of the steel strip can be performed, which is within the protection scope of the present application. Specifically, the avoiding notch may have different shapes, such as a square notch shown in fig. 1, or a shape integrated with the arc-shaped groove shown in fig. 6, and the shape of the avoiding notch is not limited in the present application, as long as the steel strip can be avoided, and all of the shapes are within the protection scope of the present application.

Referring to fig. 1, the shearing space 11 of the housing 10 is provided with an arc-shaped groove 16, the arc-shaped groove 16 can enhance the structural strength of the housing 10, and on the other hand, the steel strip can be installed in the shearing space 11 to achieve a certain avoiding effect, so that the steel strip cannot be inclined due to the abutting of the steel strip against the housing when the steel strip is placed in the shearing space, and the shearing of the steel strip is more accurate and stable.
