Referring to fig. 1-14, in one embodiment of the present invention, a metal block shearing system is provided that is capable of processing an original large sheet metal material into small square block shaped metal blocks after two consecutive processes. The metal square shearing system comprises a primary shearing unit D-1 and a secondary shearing unit D-2 which are mutually connected, wherein the primary shearing unit D-1 is used for processing a metal plate into a metal lath, so that preparation work is conveniently carried out for the production process of small blocks of the secondary shearing unit D-2 in the later stage; the secondary cutting unit D-2 is used for processing the metal lath from the primary cutting unit D-1 into a metal square block to finish final discharging.

As shown in fig. 1 to 5, the primary cutting unit D-1 includes a first gantry 100, a first cutting mechanism 200 fixed in the first gantry 100, and a fixing mechanism 300 located at the rear side of the first cutting mechanism 200, a first pushing mechanism 400 is abutted to the rear side of the first gantry 100, and a second pushing mechanism 500 is disposed below the first cutting mechanism 200.

As shown in fig. 6 to 14, the secondary cutting unit D-2 includes a second gantry 600, a second cutting mechanism 700 fixed in the second gantry 600 and connected to the second pushing mechanism 500, and a pushing mechanism 800 fixed to the rear side of the second cutting mechanism 700, and a bin 900 is provided at the front side of the second gantry 600 and located at the lower portion of the second cutting mechanism 700.

Specifically, the first portal frame 100 includes a first top plate 101 and first support columns 102 vertically fixed at two ends of the first top plate 101, which together form an inner frame, and a transverse shearing platform 103 is fixed in the inner frame.

The first shearing mechanism 200 comprises a first oil cylinder 201 (with a piston rod facing downwards) fixed on the first top plate 101 and a cutter body 202 fixed on the piston rod of the first oil cylinder 201 and forming dislocation with the inner edge of the shearing platform 103, and the cutter body 202 can perform linear motion in the vertical direction relative to the cutter body 202 by driving of the first oil cylinder 201, so that the shearing process is realized.

The fixing mechanism 300 is used for temporarily fixing the metal plate to be sheared, so that the shearing process is convenient to stably proceed. The fixing mechanism 300 is located at the rear side of the first shearing mechanism 200, and includes a second cylinder 301 (piston rod facing downward) fixed to the first gantry 100, a vertical sliding plate 302 connected to the piston rod of the second cylinder 301, and a pressing plate 303 fixed to the lower end of the sliding plate 302. The second cylinder 301 is fixed on the first support columns 102 on two sides through a cross bar 304.

Further, a vertical partition plate 104 is fixed below the shearing platform 103, a slide way 105 is fixed on the front side surface of the partition plate 104, the outer end of the slide way 105 is inclined downwards, and sheared laths can fall on the slide way 105 and discharge along the slide way 105.

Further, the shearing platform 103 is a horizontal platform-like structure, and the outer edge of the shearing platform is flush with the rear side surface of the first portal frame 100; the inner edge of the shear platform 103 is flush with the inner edge of the blade body 202, thereby forming a sheared vertical kerf plane. Preferably, the lower end surface of the cutter body 202 is obliquely arranged along the transverse direction, which is favorable for forming point contact when the cutter body 202 falls down and shears a metal plate, and has larger pressure intensity and better shearing effect.

Further, guide protrusions 202a are symmetrically arranged on two lateral sides of the cutter body 202, the guide protrusions 202a are of vertical bar-shaped protrusion structures, first vertical guide rails 102a matched with the guide protrusions 202a are arranged on the inner side surfaces of the first support columns 102, and the guide protrusions 202a are embedded into the corresponding first vertical guide rails 102a and can vertically and relatively slide.

Meanwhile, the inner side surface of the first support column 102 is further provided with second vertical guide rails 102b matched with two sides of the sliding plate 302, and two sides of the sliding plate 302 are respectively embedded into the corresponding second vertical guide rails 102b and can vertically and relatively slide.

Further, the pressing plate 303 at the lower end of the sliding plate 302 is in a plate structure horizontally arranged and is located right above the shearing platform 103, and a space exists between the pressing plate 303 and the cutter body 202. When the second cylinder 301 is driven, the squeeze plate 303 can press the metal plate placed on the shearing platform 103, so that the metal plate cannot be unstable and deviate.

In the present invention, the first pushing mechanism 400 is used for automatic supply of the original metal sheet. The first pushing mechanism 400 includes a longitudinal first bottom plate 401 with one end abutting against the outer edge of the shearing platform 103, and a third cylinder 402 disposed at the other end of the first bottom plate 401.

The first guide edges 401a for limiting are symmetrically arranged on two sides of the first bottom plate 401. The outer end of the piston rod of the third cylinder 402 is fixed with a first push plate 402a located at the upper portion of the first bottom plate 401 (and limited between the first guide edges 401a at both sides), so that the first push plate 402a can longitudinally slide between the first guide edges 401a at both sides under the pushing of the third cylinder 402. If the metal plate is placed on the first bottom plate 401, the metal plate can be gradually pushed to the inner edge of the shearing platform 103 by the step-by-step pushing of the first push plate 402a, and the actions of cutting and shearing are alternately performed, so that automation is realized. It should be noted that: a plurality of supporting legs 403 are fixed to the bottom of the first base plate 401 and support the first base plate 401. The third cylinder 402 is fixed to the outer end of the first base plate 401, and the tail of the third cylinder 402 may be fixed by support legs 403.

The second pushing mechanism 500 is used for discharging the metal lath, and sends the metal lath to the secondary shearing unit D-2 for secondary processing. When the metal plate is cut into individual metal laths and rolled off the slide 105, the second pushing mechanism 500 is used to push the discharged laths into the secondary cutting unit D-2 one by one.

Specifically, the second pushing mechanism 500 includes a second bottom plate 501 and a fourth cylinder 502 fixed on the partition 104, and the lower end of the slideway 105 is located at the upper portion of the second bottom plate 501. The second bottom plate 501 is horizontally fixed to the front side of the partition 104, and second guide edges 501a are symmetrically provided on both sides thereof. The outer end of the piston rod of the fourth cylinder 502 is fixed with a second push plate 502a positioned at the upper part of the second bottom plate 501, and the second push plate 502a can longitudinally slide between the second guiding edges 501a at two sides under the pushing of the fourth cylinder 502. When the sheared lath rolls off the slideway 105, the sheared lath can fall on the second bottom plate 501 and is positioned between the second guiding edges 501a at two sides, and the sheared lath can be pushed into the secondary shearing unit D-2 by pushing the second pushing plate 502 a.

The secondary cutting unit D-2 is used for processing the metal lath from the primary cutting unit D-1 into a metal square block to finish final discharging.

The secondary shearing unit D-2 includes a second gantry 600 and a second shearing mechanism 700 installed in the frame of the second gantry 600. The second portal frame 600 includes a horizontal second top plate 601 and second support columns 602 vertically fixed to both ends of the second top plate 601. The second shearing mechanism 700 includes an upper blade body 701 and a lower blade body 702 that are capable of moving toward each other. The outer end of the second bottom plate 501 is abutted with the lower cutter body 702, and the upper surfaces of the two are flush.

The upper blade body 701 is fixed below the second upper plate 601 by a fifth cylinder 703, and is driven by the fifth cylinder 703 to perform linear movement in the vertical direction with respect to the lower blade body 702. The fifth oil cylinder 703 is fixed on the second top plate 601, and the piston rod faces downward; the top of the upper cutter body 701 is provided with an oil cylinder connecting seat, and the lower end of a piston rod of the fifth oil cylinder 703 is fixed with the oil cylinder connecting seat to realize transmission. Specifically, the upper tool body 701 includes an upper tool holder 701a, first support posts 701b laterally arranged at the bottom of the upper tool holder 701a, and upper blades 701c fixed to the lower ends of the respective first support posts 701 b. The single first support column 701b is a plate structure vertically fixed to the bottom of the upper tool holder 701a, and the first support columns 701b are simultaneously provided with a plurality of support columns side by side in the lateral direction.

The lower blade 702 is fixed to the bottom of the second gantry 600. The lower cutter body 702 includes a lower cutter holder 702a, second support posts 702b fixed to an upper portion of the lower cutter holder 702a and staggered with the respective first support posts 701b, and a lower cutter blade 702c fixed to an upper end of the respective second support posts 702b. Thus, the upper blades 701c and the lower blades 702c are also arranged in a staggered arrangement, and preferably, the spacing between each adjacent upper blade 701c is equal to the thickness of the lower blade 702c, and the spacing between each adjacent lower blade 702c is equal to the thickness of the upper blade 701c. Thus, each first strut 701b is equally spaced laterally and vertically downward; each of the second struts 702b is arranged equidistantly in the lateral direction and vertically upward.

The upper blade body 701 can be linearly moved vertically up and down such that each upper blade 701c is inserted into a space between the corresponding lower blades 702c. Thus, if the metal lath is placed laterally on top of the upper blade 701c, the staggered upper blade 701c can be pressed downward, shearing the metal lath into a plurality of metal block structures. Preferably, the thickness of upper blade 701c is equal to the thickness of lower blade 702c, so that the size of the square cut by second shearing mechanism 700 is equal.

Further, guide plates 701d are symmetrically fixed at two lateral sides of the upper cutter body 701, third vertical guide rails 602a corresponding to the guide plates 701d are symmetrically arranged on the inner side surfaces of the second support columns 602, and the guide plates 701d at two sides of the upper cutter body 701 are respectively embedded into the corresponding third vertical guide rails 602a and can vertically slide relatively. Preferably, the outer surface of the guide plate 701d is provided with a guide wear-resistant layer made of wear-resistant material.

Further, the upper end of the upper blade 701c is connected to the lower end of the first support column 701b by a socket head cap screw, and the bottom surface of the upper blade 701c is recessed with a groove matched with the head of the screw, so that the hexagonal screw can be completely immersed in the upper blade 701c after being fixed. Similarly, the lower end of the lower blade 702c is connected to the upper end of the second support column 702b by a socket head cap screw, and the top surface of the lower blade 702c is recessed with a groove fitted to the head of the screw, so that the socket head cap screw can be completely immersed in the lower blade 702c after being fixed.

Further, the thickness of the upper blade 701c is greater than the first support post 701b, and the thickness of the lower blade 702c is greater than the second support post 702b. Thus, the dice cut by the upper blade 701c can be pushed down into the space between the second pillars 702b by the upper blade 701c, and since the thickness of the lower blade 702c is greater than that of the second pillars 702b, the space between the second pillars 702b is greater than that of the upper blade 701c (i.e., the thickness of the dice), and finally the dice pushed into between the second pillars 702b can be dropped without side friction.

Further, the upper end of the upper blade 701c is fixed to the corresponding first support post 701b, and the lower end has a longitudinal limit groove 701c-1, and the limit groove 701c-1 makes the structure of the upper blade 701c form a "U" structure in a transverse projection. When the upper blade 701c moves downward, the protruding portions on both sides have a motion limiting effect on the sheared material, preventing the position change of the sheared material caused by the absence of the action of the pressing device in the shearing process, thereby ensuring the normal shearing without the pressing device.

Further, a ramp plate 702d is fixed in the interval between each adjacent second support column 702b, and the ramp plate 702d is a plate structure which is obliquely arranged and is inclined downwards from inside to outside. The sheared square blocks, if dropped from the space of the second support column 702b, can fall on the slope plate 702d at the bottom and slide out in a proper manner.

The front side of the second portal frame 600 has a bin 900, and the bin 900 is located at the lower portion of the lower blade body 702. In addition, a discharge hopper 702e is arranged on the outer side of the slope plate 702d, the upper end of the discharge hopper 702e is fixed on the outer edge of the slope plate 702d, and the lower end of the discharge hopper 702e is inclined downwards and extends to the position right above the material box 900. The material sliding off the slope plate 702d can slide onto the discharge hopper 702e and guided by the discharge hopper 702e to finally fall into the bin 900 at the lower end of the discharge hopper 702 e.

Further, the rear side of the lower cutter body 702 has a receiving platform 702f, the receiving platform 702f is fixed (preferably in an integral structure) with the lower cutter seat 702a, and the upper end surface of the receiving platform 702f is flush with the top of the lower blade 702c. In addition, the outer end of the second bottom plate 501 is directly abutted with the outer edge of the receiving platform 702f, and the upper surfaces of the two are flush, so that the metal laths from the second bottom plate 501 can be directly pushed onto the receiving platform 702f, and when the metal laths need to be sheared, the metal laths can be pushed to the top of the lower blade 702c one by the pushing mechanism 800 for shearing by the second shearing mechanism 700.

The pushing mechanism 800 is responsible for pushing metal strips one by one and pushing and discharging metal squares, and can ensure continuous automatic feeding of cut materials and automatic discharging of finished products.

Specifically, the pushing mechanism 800 includes a mounting seat 801 fixed on the rear side of the second top plate 601, a sixth oil cylinder 802 hinged to the mounting seat 801 and having a piston rod downward, a movable joint 803 connected to the lower end of the piston rod of the sixth oil cylinder 802, and guide grooves 804 symmetrically disposed on two sides of the movable joint 803. The extending path of the guide groove 804 is a predetermined path, and determines the sliding path of the movable joint 803. The movable joint 803 can slide along a predetermined trajectory of the guide groove 804 by the pushing of the sixth cylinder 802.

Further, the path of the guide slot 804 includes three sections, respectively: a vertical section at the upper end, a curved transition section at the middle, a horizontal section at the lower end. Namely: one end of the guide groove 804 is horizontally and longitudinally bent, and the other end is upward and vertically bent.

Further, the movable joint 803 includes a plurality of cross bars 803a parallel to each other and a connecting piece 803b connecting the respective cross bars 803 a. The connecting piece 803b has connecting holes at both ends, and is movably connected with the adjacent cross bar 803a, respectively, and can relatively rotate. Preferably, the cross bar 803a is in a round bar shape, the middle position of the cross bar 803a is provided with a reducing area 803a-1, and the outer diameter of the reducing area 803a-1 is smaller than the outer diameter of the main body at two sides of the cross bar 803 a. The end of the connecting piece 803b is movably connected to the diameter-changing region 803 a-1.

Further, a collar 802a is fixed to the lower end of the piston rod of the sixth cylinder 802, and the collar 802a is sleeved on the reducing area 803a-1 of the uppermost one of the cross bars 803a and can rotate relatively. Both ends of the cross bar 803a are respectively fitted into the corresponding guide grooves 804, and can slide in the guide grooves 804.

Preferably, a plurality of cross bars 803a may be arranged in parallel, and each cross bar 803a may adaptively slide in the guide groove 804 synchronously when the sixth cylinder 802 is started, so as to form different structural configurations. Preferably, when the sixth cylinder 802 is shortened to the shortest, all the cross bars 803a can be pulled into the vertical section at the upper end, and are in a suspended state; when the sixth oil cylinder 802 is gradually extended, each cross bar 803a can be pushed to move, and the cross bar 803a at the tail end can sequentially perform a series of actions such as sliding downwards, turning, horizontal movement and the like, so as to finally push the material to be sheared (or sheared small material) at the same horizontal position, thereby realizing the feeding (or discharging) process.

The invention sets that: the guide groove 804 has an upper end (vertical section) located directly above the receiving platform 702f and a lower end (horizontal section) bent to extend across the receiving platform 702f and to an upper portion of the lower blade 702c (located on both sides of the lower blade 702 c). When the metal laths to be sheared are sequentially pushed onto the receiving platform 702f, the cross bar 803a at the lowest end can push one metal lath in a homeopathic manner when sliding downwards to a bending position, push the metal lath to the middle position of the top of the lower blade 702c, and then return; when the metal lath is cut into small cubes, a part of the small cubes located at the top of the lower blade 702c slides down again due to the depth pushing (horizontal movement distance is greater) of the cross bar 803a, so that discharging is achieved.

The secondary shearing unit D-2 further includes a rejecting mechanism 1000 transversely fixed in the frame of the second portal frame 600 and inserted between the upper cutter body 701 and the lower cutter body 702, which can ensure that the material clamping or material entrainment can not occur in the material cutting process of the second shearing mechanism 700.

Specifically, the rejecting mechanism 1000 includes a cross beam 1001 with two ends respectively fixed on the second support columns 602 at two sides, the cross beam 1001 has a pair of parallel to each other, and rejecting teeth 1002 are arranged between the two cross beams 1001 at intervals. The pair of parallel cross beams 1001 are an inner cross beam 1001a and an outer cross beam 1001b, and first through holes 1001a-1 and second through holes 1001b-1 which are opposite to each other and are in one-to-one correspondence are respectively arranged on the inner cross beam 1001a and the outer cross beam 1001b, and each tooth pick 1002 is respectively inserted and fixed in a corresponding group of the first through holes 1001a-1 and the second through holes 1001 b-1.

Further, both ends of the inner cross member 1001a and the outer cross member 1001b are respectively fixed with a fixing plate, which is fixed to the inner side surface of the second support column 602 by bolts.

Further, the tooth picking 1002 main body is in a cylindrical structure, the outer diameter of the tooth picking main body is matched with the inner diameters of the first perforation 1001a-1 and the second perforation 1001b-1, two ends of the tooth picking 1002 are respectively provided with an inner end 1002a and an outer end 1002b, a limit head 1002a-1 with a larger outer diameter is fixed on the inner end 1002a, the limit head 1002a-1 is blocked outside the first perforation 1001a-1, and meanwhile, the outer end 1002b penetrates out of the second perforation 1001 b-1.

Further, the rejecting mechanism 1000 further includes a platen 1003 having a strip shape, and a lateral slot 1002b-1 is provided on an outer side surface of an outer end 1002b of each rejecting tooth 1002, and a width of the slot 1002b-1 is matched with a thickness of the platen 1003. When each pick 1002 is inserted into the corresponding first and second perforations 1001a-1, 1001b-1 such that the spacing head 1002a-1 forms a spacing, the inside edge of the slot 1002b-1 is just flush with the outside of the second perforation 1001b-1, and the platen 1003 can be inserted into the slot 1002b-1 of each pick 1002, forming a spacing for that end.
