Description

[0002] Steel plate stamping is a part processing method, in which the steel plate is stamped in the corresponding mold to obtain the desired shape. The existing steel plate stamping device has the following defects: First, considering that the friction between the steel plate and the mold will cause wear to the steel plate during steel plate stamping and affect the forming accuracy of the steel plate, it is necessary to apply stamping oil to the surface of the steel plate before stamping the steel plate. The stamping oil can also prevent the steel plate from rusting after stamping and can take away the heat generated during stamping to extend the life of the mold. The existing oiling method is to use a nozzle to spray oil on the steel plate, which is easy to cause large consumption of stamping oil, easy to spill out of the steel plate to affect the cleanliness of the table, and the sprayed oil mist is easy to be absorbed by the workers and cause damage to the body; Second, after the steel plate is stamped, the bent steel plate is tightly fitted with the inner wall of the die, which easily makes it difficult to remove the steel plate embedded in the die smoothly, and cannot be automatically demolded, which requires more time and manpower; For this reason, we propose a steel plate stamping device.

The material picking mechanism 400 includes a first extrusion component 401 arranged at the bottom end of the workbench 100 and matched with the bottom end of the push rod 204f. A cross plate 205 is fixed to one side of the piston rod end of the hydraulic cylinder 202. The cross plate 205 is located at the bottom end of one side of the rectangular through hole 101 and is respectively provided with a transmission component 304 matched with the clamping component 305, and a second extrusion component 402 matched with the first extrusion component 401.

[0021] Preferably, the oil delivery assembly 302 includes a driving gear 302a and a driven gear 302b that mesh with each other, and a driving shaft 302c and a driven shaft 302d are respectively fixed through the middle of the driving gear 302a and the driven gear 302b, and the driving shaft 302c and the driven shaft 302d are respectively rotatably set on the inner wall of the oil delivery housing 301, and one end of the driving shaft 302c extends outward through the inner wall of the oil delivery housing 301 and is provided with a transmission gear 303.

The stamping oil enters the oil storage cavity 204a from the oil inlet hole 204c. As the stamping oil in the oil storage cavity 204a increases, the stamping oil overflows from the long strip oil outlet hole 204b and flows down along the inner wall of the lower concave die 204. When the driving gear 302a stops rotating, the stamping oil no longer enters the oil storage cavity 204a from the oil inlet hole 204c.

[0023] Preferably, the clamping assembly 305 includes a mounting block 305a arranged on the side wall of the oil delivery housing 301, and the first rotating shaft 305b and the second rotating shaft 305c are respectively arranged on the lower part and the upper left part of the end face of the mounting block 305a, and the first clamping block 305d is rotatably arranged on the outer wall of the first rotating shaft 305b, and a first inclined surface 305d-1 is formed at one end of the first clamping block 305d, and a third rotating shaft 305e is arranged on the side wall of the first clamping block 305d, and a torsion spring 305f is sleeved on the outer wall of the first rotating shaft 305b, and the two ends of the torsion spring 305f are respectively sleeved on the second rotating shaft 305c and the third rotating shaft 305e, and a first baffle 305g is arranged on the end face of the mounting block 305a, and the bottom end of the first clamping block 305d in a horizontally placed state is movably overlapped on the top of the first baffle 305g.

[0024] Preferably, the transmission assembly 304 includes a transmission plate 304a arranged at the bottom end of the cross plate 205, the bottom end of the transmission plate 304a passes through the rectangular through hole 101 and is provided with a transmission block 304b, the bottom of the transmission block 304b is provided with a mounting groove 304b-1, a clamping plate 304c is movably provided in the mounting groove 304b-1, a plurality of clamping teeth 304c-1 are evenly distributed on one side of the clamping plate 304c corresponding to the transmission gear 303, the other side of the clamping plate 304c corresponds to the first clamping block 305d, a second inclined surface 304c-2 is formed at the bottom end of the clamping plate 304c, a plurality of limiting holes 304b-2 are provided on the bottom wall of the mounting groove 304b-1, a plurality of limiting columns 304c-3 penetrating the limiting holes 304b-2 are provided on the back of the clamping plate 304c, and the outer wall of the limiting column 304c-3 is sleeved with a first spring 304d.

[0025] The steel plate is placed on the top of the lower concave die 204. During the process of controlling the extension of the piston rod of the hydraulic cylinder 202, the piston rod of the hydraulic cylinder 202 drives the horizontal plate 205 to move downward. The transmission plate 304a at the bottom of the horizontal plate 205 drives the transmission block 304b to move downward. The clamping plate 304c in the mounting groove 304b-1 at the bottom of the transmission block 304b first contacts the first clamping block 305d. During the contact process, the first inclined surface 305d on the first clamping block 305d -1 squeezes the second inclined surface 304c-2 at the bottom end of the clamping plate 304c. Since the bottom end of the first clamping block 305d in the horizontal state is movably overlapped with the top end of the first baffle 305g, the first clamping block 305d can be forced to squeeze the clamping plate 304c, so that the clamping plate 304c is squeezed into the installation groove 304b-1, preventing the multiple clamping teeth 304c-1 on the clamping plate 304c from meshing with the transmission gear 303 and then driving the transmission gear 303 After the first engaging teeth 304a and 304b are engaged with the transmission gear 303, the first engaging teeth 304a and 304b are engaged with the transmission gear 303, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 304c-1, and the transmission gear 303 is engaged with the first engaging teeth 302a, and the transmission gear 303 is engaged with the first engaging teeth 302a, and the transmission gear 303 is engaged with the first engaging teeth 304c-1 ...

[0026] Preferably, the first extrusion assembly 401 includes a fixed plate 401a arranged at the bottom end of the workbench 100, a fixed ring 401b is arranged at the bottom end of the fixed plate 401a, an inner ring of the fixed ring 401b is fixedly provided with an extrusion cylinder 401c with an internal hollow structure, a sliding rod 401d is slidably penetrated inside the extrusion cylinder 401c, one end of the sliding rod 401d close to the rectangular through hole 101 is connected to the extrusion rod 401e, and a second clamping block 401f is arranged at the other end of the sliding rod 401d, and the second clamping block 401f forms a second inclined surface 401f-1 on the side facing the push rod 204f, and a first annular baffle 401d-1 is arranged on the outer wall of the sliding rod 401d located in the extrusion cylinder 401c, and a second spring 401g is arranged between the annular baffle 401d-1 and the inner wall of the extrusion cylinder 401c, and the second spring 401g is sleeved on the outer wall of the sliding rod 401d.

[0027] When the slide rod 401d is subjected to pressure and moves toward the push rod 204f, the second inclined surface 401f-1 on the second clamping block 401f pushes the push rod 204f to move upward, and the push rod 204f drives the push plate 204e to push the stamped steel plate upward to prevent the steel plate from being difficult to remove after being stamped. When the slide rod 401d is not subjected to thrust, the second spring 401g pushes the slide rod 401d to return to its original position through the annular baffle 401d-1.

[0028] Preferably, the second extrusion assembly 402 includes a connecting plate 402a arranged at the bottom end of the horizontal plate 205, the bottom end of the connecting plate 402a passes through the rectangular through hole 101 and is provided with a moving block 402b, the side wall of the moving block 402b is provided with a fourth rotating shaft 402b-1, the outer wall of the fourth rotating shaft 402b-1 is rotatably provided with a rotating plate 402c, one end of the rotating plate 402c is provided with a third clamping block 402d, the end of the third clamping block 402d facing the extrusion rod 401e is provided with a third inclined surface 402d-1, a pull plate 402e and a second baffle 402f are provided below the side wall of the moving block 402b, the bottom end of the third clamping block 402d in a horizontally placed state is movably overlapped with the top end of the second baffle 402f, and an elastic rope 402e-1 is provided between the top of the pull plate 402e and the bottom end of the rotating plate 402c.

[0029] When the piston rod of the hydraulic cylinder 202 is extended, it drives the cross plate 205 to move downward, and the connecting plate 402a at the bottom of the cross plate 205 drives the moving block 402b to move downward. During the downward movement, the third clamping block 402d contacts the extrusion rod 401e, and the top of the extrusion rod 401e pushes the third clamping block 402d to rotate. After the moving block 402b moves down to the bottom of the extrusion rod 401e, the elastic rope 402e-1 connected to the rotating plate 402c pulls the rotating plate 402c to drive the third clamping block 402d to return to its original position. After the hydraulic cylinder 202 piston rod is extended to stamp the steel plate, the hydraulic cylinder 202 piston rod contracts and drives the cross plate 205 to move upward, thereby driving the moving block 402b to move upward. During the upward movement, the third inclined surface 402d-1 on the third clamping block 402d squeezes the extrusion rod 401e to drive the sliding rod 401d to move toward the push rod 204f.

[0030] Preferably, a hemispherical slider 204f-1 is provided at the bottom end of the push rod 204f, a second annular baffle 206 is provided on the outer wall of the push rod 204f located at the bottom end of the workbench 100, a third spring 206a is provided between the top end of the second annular baffle 206 and the bottom end of the workbench 100, and the third spring 206a is sleeved on the outer wall of the push rod 204f.

[0031] The hemispherical slider 204f-1 at the bottom of the push rod 204f contacts the second inclined surface 401f-1 on the second clamping block 401f to reduce friction. After the second clamping block 401f pushes the push rod 204f to move up and out of the steel plate, the push rod 204f is driven downward by the elastic force of the third spring 206a. The push rod 204f drives the push plate 204e back into the sampling hole 204d.

[0032] Principle of use: Place the steel plate on the top of the lower die 204, and during the process of controlling the extension of the piston rod of the hydraulic cylinder 202, the piston rod of the hydraulic cylinder 202 drives the cross plate 205 to move downward, and the transmission plate 304a and the connecting plate 402a at the bottom of the cross plate 205 respectively drive the transmission block 304b and the moving block 402b to move downward, and the clamping plate 304c in the mounting groove 304b-1 at the bottom of the transmission block 304b first contacts with the first clamping block 305d. During the contact process, the first inclined surface 305d-1 on the first clamping block 305d squeezes the second inclined surface 304c-2 at the bottom of the clamping plate 304c. Since the bottom end of the first clamping block 305d in the horizontal horizontal state is movably overlapped with the top end of the first baffle 305g, the first clamping block 305d can The clamping plate 304c is squeezed by the force, so that the clamping plate 304c is squeezed into the installation groove 304b-1, preventing the multiple clamping teeth 304c-1 on the clamping plate 304c from meshing with the transmission gear 303 and thereby driving the transmission gear 303 to rotate. As the transmission block 304b continues to move downward, until the clamping plate 304c and the first clamping block 305d are disengaged, the clamping plate 304c pops out the squeezed part under the action of the first spring 304d, and during the downward movement of the moving block 402b, the third clamping block 402d contacts the squeezing rod 401e, and the top of the squeezing rod 401e pushes the third clamping block 402d to rotate. After the moving block 402b moves down to below the squeezing rod 401e, the elastic rope 402e-1 connected to the rotating plate 402c Pulling the rotating plate 402c drives the third clamping block 402d to return to its original position. After the piston rod of the hydraulic cylinder 202 extends and drives the upper punch 203 to press into the lower concave die 204 to complete the stamping of the steel plate, the piston rod of the hydraulic cylinder 202 contracts, thereby driving the cross plate 205 to move upward, and the transmission block 304b and the moving block 402b are also driven to move upward. During the upward movement, the top of the clamping plate 304c squeezes the first clamping block 305d to rotate counterclockwise, and the multiple clamping teeth 304c-1 on the clamping plate 304c mesh with the transmission gear 303 to drive the transmission gear 303 to rotate. The transmission gear 303 then rotates to drive the driving gear 302a. The driving gear 302a rotates clockwise, and the driving gear 302a, the driven gear 302b and the oil delivery gear 302a rotate clockwise. A low-pressure area is formed between the holes 301b, and a high-pressure area is formed between the driven gear 302b and the oil discharge hole 301c. The driving gear 302a rotates clockwise to drive the driven gear 302b to rotate counterclockwise. The low-pressure area drives the oil inlet hose 301e to absorb the stamping oil in the external stamping oil tank to fill the entire waist-shaped cavity 301a. The stamping oil located between the inner wall of the waist-shaped cavity 301a and the teeth of the driving gear 302a and the driven gear 302b is brought into the high-pressure area and enters the oil inlet hole 204c through the oil delivery hose 301d. The stamping oil enters the oil storage cavity 204a from the oil inlet hole 204c. As the stamping oil in the oil storage cavity 204a increases, the stamping oil overflows from the long strip oil outlet hole 204b and flows down along the inner wall of the lower concave die 204.In order to prepare for the next stamping of the steel plate, the first clamping block 305d is restored to its original position under the action of the torsion spring 305f after the clamping plate 304c is disengaged from the transmission gear 303. At this time, when the driving gear 302a also stops rotating, the stamping oil no longer enters the oil storage chamber 204a through the oil inlet hole 204c. The number of rotations of the transmission gear 303 can be controlled by setting the number of clamping teeth 304c-1 on the clamping plate 304c, thereby achieving precise control of the oil output and preventing waste of stamping oil. At the same time, when the moving block 402b moves up, the third inclined plate 402d on the third clamping block 402d is The surface 402d-1 squeezes the squeezing rod 401e and drives the slide bar 401d to move toward the push rod 204f. The second inclined surface 401f-1 on the second clamping block 401f at the end of the slide bar 401d pushes the push rod 204f to move upward. The push rod 204f drives the push plate 204e to push the stamped steel plate upward to prevent the steel plate from being difficult to remove after being stamped. When the moving block 402b continues to move upward, the slide bar 401d is not pushed. The second spring 401g pushes the slide bar 401d to return to its original position through the annular baffle 401d-1.
