Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine equipped with a feeding protection structure. Background Technology

[0002] Shearing machines are mainly used for shearing metal sheets. Their working principle is to apply shearing force to metal sheets of different thicknesses by using an upper blade and a fixed lower blade with a reasonable blade gap, so that the sheets are separated into the required dimensions.

[0003] In a shearing machine, the cutting blade (upper blade) is located at the top, and the cutting table (lower blade) is located at the bottom, with the metal sheet sandwiched between them. By pressing down with the upper cutting blade, the metal sheet is pressed onto the cutting table, generating a shearing force that cuts the metal sheet into the desired shape and size.

[0004] When using existing shearing machines, the operator pushes the metal sheet between the upper and lower blades and presses the metal sheet with both hands to limit its movement. However, if the reverse force of the blades on the metal sheet is too large during the cutting process, it can easily cause injury to the operator. Summary of the Invention

[0005] The purpose of this utility model is to provide a shearing machine with a feeding protection structure, which can fix the metal sheet during shearing without the need for manual fixing of the metal sheet, and can provide a certain degree of protection for the operator, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shearing machine with a feeding protection structure, comprising a shearing machine body, a feeding mechanism for feeding is provided at the front end of the shearing machine body, and a feeding roller for supporting metal sheets is provided below the feeding mechanism. A feeding plate is provided at the front end of the feeding roller. A fixing protection mechanism for fixing metal sheets is provided on the feeding mechanism. An upper blade is slidably installed inside the shearing machine body, and a lower blade is provided below the upper blade.

[0007] The fixed protection mechanism includes a lifting and movable clamping plate, and a number of equally spaced and evenly distributed rotating shafts are installed at the bottom of the clamping plate.

[0009] Preferably, the bottom of the lifting slider is provided with a support spring, and the outside of the lifting slider is provided with a lifting groove, and the lifting slider is slidably connected to the lifting groove through the support spring.

[0010] Preferably, the feeding mechanism includes a supporting front plate fixed to the top of the feeding plate, a supporting member is provided at the rear end of the supporting front plate, and the lifting slide is formed on the side surface of the supporting member.

[0011] Preferably, a feed screw is installed between the support member and the front support plate, and a feed push plate is connected to the outside of the feed screw through a screw sleeve, the feed push plate being parallel to the front support plate.

[0012] Preferably, a lifting platform is installed on the top of the upper blade, and the top of the lifting platform is equipped with the telescopic end of a hydraulic cylinder.

[0013] Preferably, a support slider and a support groove adapted to the support slider are provided at the connection between the lifting platform and the shearing machine body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4 A shearing machine with a feeding protection structure includes a shearing machine body 1, a feeding mechanism 3 for feeding is provided at the front end of the shearing machine body 1, a feeding roller 5 for supporting metal sheets is provided below the feeding mechanism 3, a feeding plate 2 is provided at the front end of the feeding roller 5, a fixing protection mechanism 4 for fixing the metal sheets is provided on the feeding mechanism 3, an upper blade 8 is slidably installed inside the shearing machine body 1, and a lower blade 9 is provided below the upper blade 8.

[0027] The fixed protection mechanism 4 includes a lifting and movable clamping plate 403, and a number of equally spaced rotating shafts 406 are installed at the bottom of the clamping plate 403, and a number of equally spaced rollers 407 are installed on the outside of the rotating shafts 406.

[0028] The fixed protection mechanism 4 also includes a lifting slider 402 fixed to one side of the clamping plate 403. The top of the lifting slider 402 is equipped with an adjusting screw 401 through a bearing. The bottom of the lifting slider 402 is provided with a support spring 404. The outside of the lifting slider 402 is provided with a lifting groove 405. The lifting slider 402 is slidably connected to the lifting groove 405 through the support spring 404.

[0029] By adopting the above technical solution, when the metal sheet is sheared, the metal sheet can be placed between the clamping plate 403 and the feeding roller 5. As the feeding mechanism 3 pushes, the metal sheet drives the roller 407 to roll, thereby driving the rotating shaft 406 to rotate inside the clamping plate 403 through the roller 407. This allows the clamping plate 403 to firmly clamp the metal sheet when it is fed, eliminating the need for the operator to hold the metal sheet for positioning and avoiding injury to the operator due to the large reaction force generated during cutting.

[0030] Furthermore, when the clamping plate 403 is in use, the knob on the adjusting screw 401 can be rotated to drive the adjusting screw 401 to rotate, thereby pushing the lifting slider 402 on the adjusting screw 401 to slide and connect inside the lifting groove 405, and squeezing the support spring 404 to adjust the height of the clamping plate 403 so that the clamping plate 403 can be adapted to metal plates of different thicknesses.

[0031] Specifically, such as Figure 4 As shown, the feeding mechanism 3 includes a support front plate 303 fixed to the top of the feeding plate 2. A support member 304 is provided at the rear end of the support front plate 303. A lifting slide 405 is opened on the side surface of the support member 304. A feeding screw 302 is installed between the support member 304 and the support front plate 303. The outside of the feeding screw 302 is connected to the feeding push plate 301 through the screw sleeve. The feeding push plate 301 is parallel to the support front plate 303.

[0032] A lifting platform 6 is installed on the top of the upper blade 8, and the telescopic end of the hydraulic cylinder 7 is installed on the top of the lifting platform 6. A support slider 10 is provided at the connection between the lifting platform 6 and the shearing machine body 1, and a support slide groove adapted to the support slider 10 is provided. The support slide groove is located on the inner wall of the shearing machine body 1, and a discharge port is provided at the rear end of the shearing machine body 1.

[0033] By adopting the above technical solution, during feeding, since the feeding pusher plate 301 is above the feeding roller 5, when the feeding screw 302 rotates under the action of the screw motor, the feeding pusher plate 301 can be moved on the feeding screw 302 through the screw sleeve, thereby pushing the metal plate placed on one side of the feeding pusher plate 301, so that the metal plate gradually approaches the cutting area.

[0034] After the metal sheet enters the cutting area, the hydraulic cylinder 7 can be activated. The telescopic end of the hydraulic cylinder 7 pushes the lifting platform 6 to slide. At this time, the support slider 10 slides inside the support groove, guiding and limiting the lifting platform 6, so that the upper blade 8 and the lower blade 9 move closer to each other, and cut the metal sheet located between the upper blade 8 and the lower blade 9 to achieve plate shearing.

[0035] Working principle: When the metal sheet is being sheared, the feeding screw 302 rotates under the action of the screw motor. This rotation drives the feeding push plate 301 to move on the feeding screw 302, thus pushing the metal sheet placed on one side of the feeding push plate 301 closer to the cutting area. Turning the knob on the adjusting screw 401 rotates the adjusting screw 401, causing the lifting slider 402 on the adjusting screw 401 to slide within the lifting groove 405, and compressing the support spring 404. This adjusts the height of the clamping plate 403, allowing it to adapt to metal sheets of different thicknesses. The metal sheet is located between the clamping plate 403 and the feeding roller 5. As the feeding mechanism 3 pushes, the metal sheet causes the roller 407 to roll, which in turn causes the rotating shaft 406 to rotate inside the clamping plate 403. This allows the clamping plate 403 to firmly clamp the metal sheet during feeding. After the metal sheet enters the cutting area, the hydraulic cylinder 7 can be activated. The telescopic end of the hydraulic cylinder 7 pushes the lifting platform 6 to slide. At this time, the support slider 10 slides inside the support groove, guiding and limiting the lifting platform 6, so that the upper blade 8 and the lower blade 9 move closer to each other, cutting the metal sheet located between the upper blade 8 and the lower blade 9, thus achieving plate shearing.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
