Description

Technical Field

[0001] The invention relates to the field of steel cutting equipment, in particular to a die steel fixed-length cutting equipment. Background Art

[0002] Die steel is a steel material used to make various dies, such as cold stamping dies, hot forging dies, die casting dies, etc. Dies are important tools for manufacturing parts in industrial production. The quality of die steel directly affects the quality of die processing technology, product precision, output and production cost.

[0003] Mold steel materials are usually in the shape of rectangular strips or rods. During the processing of mold steel, the mold steel materials need to be cut into several mold steel blanks at a fixed length to facilitate the subsequent processing of the mold steel blanks into molds. In the prior art, when cutting mold steel materials to a fixed length, a fully automatic high-speed circular saw cutting machine is usually used to perform fully automatic fixed-length cutting of mold steel. The circular saw cutting machine pushes the clamping structure to clamp the mold steel material through a hydraulic cylinder, and then drives the clamping structure to move intermittently through a lead screw, thereby achieving fixed-length pushing of the mold steel material, and controlling the feed amount of the mold steel material each time by controlling the angle of each intermittent rotation of the lead screw.

[0004] However, when the existing circular saw cutting machine cuts the longer mold steel material, due to the long length of the mold steel material, the lead screw needs to drive the clamping structure to move back and forth, so that the clamping structure can continue to push the longer mold steel material to a fixed length. However, when the clamping structure is in the return position, the bottom plate of the clamping structure will rub against the bottom surface of the mold steel material, thereby causing wear on the bottom surface of the mold steel, affecting the cutting effect of the mold steel material. In addition, the method of clamping and pushing the mold steel material by driving the clamping structure with a lead screw can only be achieved after the clamping structure completes clamping the mold steel material, and then the lead screw can be rotated to drive the mold steel material to push, so that there is a gap between the clamping and pushing actions, thereby reducing the pushing efficiency and affecting the cutting efficiency.

[0020] Beneficial effects of the present invention:

[0021] 1. The positioning mechanism adopted in the present invention contacts the mold steel material in the form of rolling contact, and the rolling contact points are evenly distributed in the four directions of the mold steel material, thereby preventing the positioning mechanism from sliding friction with the mold steel material, causing wear of the mold steel material, and ensuring the cutting effect and cutting accuracy of the mold steel material. The control component controls the push plate not to contact the mold steel material during the reset movement. On the one hand, it avoids the push plate from driving the mold steel material to move during the reset movement and affecting the pushing accuracy of the mold steel material. On the other hand, it avoids sliding friction between the push plate and the mold steel material, thereby further ensuring the cutting effect and accuracy.

[0022] 2. The power component used in the present invention drives the two active plates to approach each other synchronously, so that the active plates drive the pushing plates to clamp the left and right sides of the mold steel material through the connecting plates, and then the power component continues to drive the two active plates to approach each other, so that the active plates push the mold steel material forward through the pushing plates, thereby achieving immediate fixed-length pushing of the mold steel material after clamping, connecting the clamping and pushing operations together, thereby eliminating the waiting interval between clamping and pushing, and improving the cutting efficiency of the mold steel material.

[0023] 3. The auxiliary clamping assembly used in the present invention can avoid the position of the push plate, thereby preventing the auxiliary clamping assembly from hindering the movement of the push plate, thereby ensuring that the push plate can stably push the mold steel material. In addition, by rotating the No. 1 bidirectional screw, the distance between the two position plates can be adjusted, thereby changing the pushing distance of the push plate to the mold steel material, thereby adapting to cutting requirements of different lengths.

[0024] 4. The push rod assembly used in the present invention has the function of adjusting the clamping contact mode according to the shape of the mold steel material. For rectangular mold steel materials, a multi-directional surface contact clamping mode is adopted, and for rod-shaped mold steel materials, a circumferential tangent line contact clamping mode is adopted. By matching different shapes of mold steel materials with different clamping contact modes, the push plate can push the mold steel material more stably, thereby avoiding slipping and friction and ensuring the accuracy of pushing.

DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0040] See also Figure 1 , Figure 2 and Figure 7 A mold steel fixed-length cutting device includes a base 1, a support member 11 is symmetrically and fixedly installed on the front side of the base 1, a cutting saw 2 is arranged on the front upper side of the left support member 11 for sliding left and right through an electric slider, and the electric slider is not shown in the figure, a pushing mechanism 3 for pushing the mold steel material of fixed length is arranged in the middle of the base 1, and a positioning mechanism 4 for centering and clamping the mold steel material is arranged on the base 1.

[0041] When the mold steel material needs to be cut, the operator first places the mold steel material inside the positioning mechanism 4, clamps the mold steel material in the middle position of the pushing mechanism 3 through the positioning mechanism 4, then pushes the mold steel material to a fixed length through the pushing mechanism 3, and then cuts the mold steel material to a fixed length through the cutting saw 2.

[0042] See also Figure 1 , Figure 2 and Figure 3 The positioning mechanism 4 includes a bracket member 41 which is symmetrical and fixedly installed on the rear side of the base 1. A limit assembly 45 for continuously clamping the mold steel material is arranged on the rear side of the bracket member 41. The limit assembly 45 includes a supporting circular plate 451 which is fixedly installed on the rear sides of the two bracket members 41. A clamping frame 452 which slides along its radial direction is arranged at equal intervals along the circumference of the rear side of the supporting circular plate 451. A rotating wheel 453 is rotatably arranged at one end of the clamping frame 452 close to the axis of the supporting circular plate 451. An active column 454 is fixedly installed on the front side of the clamping frame 452. A rotating circular plate 455 is rotatably arranged on the front side of the supporting circular plate 451. Vortex grooves 456 are opened on the rotating circular plate 455 at equal intervals along the circumference of the rotating circular plate 455. The active column 454 slides inside the corresponding vortex grooves 456.

[0043] When the mold steel material needs to be positioned, the operator moves the mold steel material to the rear side of the supporting circular plate 451 through the existing transporting device, and then the operator assists the transporting equipment to insert one end of the mold steel material into the interior of the supporting circular plate 451. Then the operator manually rotates the rotating circular plate 455, so that the rotating circular plate 455 drives the active column 454 to move radially along the supporting circular plate 451 through the vortex groove 456 thereon, so that the active column 454 drives the rotating wheel 453 to clamp on the side of the mold steel material through the clamping frame 452, thereby preliminarily positioning the mold steel material, and then the operator cooperates with the transporting equipment to move the mold steel material forward.

[0044] It should be noted that a plurality of positioning holes are provided at equal intervals along the circumference of the rotating circular plate 455, and a positioning pin is slidably provided on the supporting circular plate 451. When the operator drives the rotating wheel 453 to clamp the side of the mold steel material through the rotating circular plate 455, the operator moves the positioning pin forward so that the positioning pin is inserted into the interior of the rotating circular plate 455 and the supporting circular plate 451 at the same time, thereby fixing the rotation angle of the rotating circular plate 455.

[0045] See also Figure 1 , Figure 2 and Figure 4The left bracket member 41 and the support member 11 are fixedly installed with a guide column 42 on one side close to the center of the base 1, and a centering frame 43 symmetrically arranged on the guide column 42 is slidably provided. A plurality of abutment wheels 44 are rotatably arranged on the side close to each other along the front-to-back direction. A No. 2 threaded rod 411 is rotatably arranged on the right bracket member 41, and two threaded sections of the No. 2 threaded rod 411 are respectively threadedly connected with the two centering frames 43.

[0046] When the mold steel material moves forward to between the centering frames 43, the operator rotates the No. 2 threaded rod 411 to drive the two centering frames 43 closer to each other, so that the centering frames 43 drive the abutment wheels 44 thereon to clamp the mold steel material, so that the abutment wheels 44 can support and position the mold steel material.

[0047] See also Figure 1 , Figure 2 and Figure 5 An auxiliary clamping assembly 46 for limiting the position of the mold steel material close to the cutting saw 2 is provided on the support member 11. The auxiliary clamping assembly 46 includes a movable roller frame 461 which is symmetrical and slides left and right on the front side of the support member 11. A return spring for pushing the movable roller frame 461 on the left to the right is provided between the movable roller frame 461 on the left and the support member 11 on the left. A push roller 462 is rotatably provided on one side of the movable roller frame 461 close to the middle of the base 1. A linkage plate 463 is hinged on the upper part of the movable roller frame 461. A fixed plate 464 is fixedly installed on the upper part of the two guide columns 42 on the front side. A rotating plate 465 is rotatably provided on the rear side of the fixed plate 464. The left and right ends of the rotating plate 465 are respectively hinged to the linkage plate 463 at the corresponding position.

[0048] When the mold steel material moves forward to the position of the moving roller frame 461, the return spring pushes the moving roller frame 461 on the left to the right, so that the moving roller frame 461 on the left drives the push roller 462 thereon to press against the left side of the mold steel material. At the same time, the moving roller frame 461 on the left drives the rotating plate 465 to rotate through the linkage plate 463 on the left, and the rotating plate 465 drives the moving roller frame 461 on the right to move synchronously to the left through the linkage plate 463 on the right, so that the moving roller frame 461 drives the push roller 462 thereon to press against and clamp the left and right sides of the mold steel material.

[0049] See also Figure 2 , Figure 5 and Figure 6A stop portion 466 is provided on the right support member 11 to prevent the movable roller frame 461 from accidentally sliding. The stop portion 466 includes an insertion card 4661 which is slidably arranged on the upper part of the right support member 11. A plurality of tooth grooves 4662 are provided on the upper front side of the right movable roller frame 461 at equal intervals along the left-right direction. An active spring is provided between the insertion card 4661 and the right support member 11 to push the insertion card 4661 backward.

[0050] Before the mold steel material moves to the position of the movable roller frame 461, the operator needs to manually pull the insertion card 4661 forward so that the insertion card 4661 exits the interior of the card slot 4662, thereby allowing the movable roller frame 461 on the right to slide left and right. Then the operator pulls the movable roller frame 461 away from the middle of the base 1 so that the movable roller frames 461 can move away from each other, and the movable roller frame 461 on the left compresses the return spring, thereby facilitating the mold steel material to move between the movable roller frames 461.

[0051] When the mold steel material reaches between the moving roller frame 461, the moving roller frame 461 on the left is loosened. When the moving roller frame 461 on the left moves to the right under the rebound force of the return spring, the external force on the insertion card 4661 is removed, so that the active spring pushes the insertion card 4661 to be inserted into the corresponding tooth groove 4662. When the moving roller frame 461 on the right moves to the left, the insertion card 4661 can contact the inclined surface of the tooth groove 4662. The insertion card 4661 moves forward under the action of the inclined surface and compresses the active spring, so that the insertion card 4661 cannot hinder the moving roller frame 461 from moving toward the middle of the base 1, that is, moving to the left.

[0052] The insertion clamp 4661 cooperates with the flat surface of the latch groove 4662 to prevent the latch groove 4662 from moving to the right, thereby limiting the movement of the movable roller frame 461, so that the movable roller frame 461 can drive the push roller 462 to stably clamp and position the front of the mold steel material.

[0053] See also Figure 1 , Figure 7 and Figure 8 The pushing mechanism 3 includes a position plate 31 which is symmetrical and slides left and right on the upper side of the base 1. A No. 1 bidirectional screw 12 is rotatably arranged on the upper part of the base 1. Two threaded sections of the No. 1 bidirectional screw 12 are respectively threadedly connected to the two position plates 31.

[0054] The operator rotates the No. 1 bidirectional screw 12 as needed, so that the No. 1 bidirectional screw 12 drives the two position plates 31 to move closer to or farther away from each other, thereby adjusting the pushing distance of the mold steel each time. When it is necessary to increase the pushing length of the mold steel each time, the operator rotates the No. 1 bidirectional screw 12 to drive the two position plates 31 closer to each other, and vice versa.

[0055] See also Figure 1 , Figure 7 and Fig. 9 An active plate 32 is provided on one side of the position plate 31 close to the center of the base 1 for sliding left and right. Two connecting plates 33 are hinged on one side of the active plate 32 close to the center of the base 1. The two connecting plates 33 are arranged front and back on the active plate 32. A push plate 34 is hinged on one side of the two connecting plates 33 opposite to each other close to the center of the base 1. The active plate 32, the two connecting plates 33 and the push plate 34 form a parallelogram structure.

[0056] Since the active plate 32, the two connecting plates 33 and the pushing plate 34 form a parallelogram structure, the active plate 32 and the pushing plate 34 are always parallel to each other. Since the active plate 32 is parallel to the mold steel material, the pushing plate 34 is also always parallel to the mold steel material. When the distance between the active plate 32 and the pushing plate 34 decreases, since the length of the connecting plate 33 cannot be changed, the end of the connecting plate 33 close to the middle of the base 1 gradually moves relatively to the front side, and then the connecting plate 33 drives the pushing plate 34 to move forward, and the pushing plate 34 and the active plate 32 change from the original left-right relative state to the left-right staggered state.

[0057] See also Figure 7 , Fig. 9 and Fig.10 A push rod assembly 35 for assisting in pushing the rod-shaped materials is provided on the pushing plate 34. The push rod assembly 35 includes a laminating plate 351 which is symmetrical up and down and hinged on the side of the pushing plate 34 close to the center of the base 1. A push-pull plate 352 is hinged on the middle part of the laminating plate 351 away from the center of the base 1. An adjusting plate 353 is hinged on the end of the push-pull plate 352 at the same pushing plate 34 away from the center of the base 1. An adjusting threaded rod 354 is rotatably provided on the side of the pushing plate 34 away from the center of the base 1, and the adjusting threaded rod 354 is threadedly connected to the adjusting plate 353.

[0058] When the cross-section of the mold steel material is rectangular, the adjusting threaded rod 354 is rotated to drive the adjusting plate 353 to move away from the middle of the base 1, so that the adjusting plate 353 pulls the bonding plate 351 at the corresponding position to rotate through the push-pull plate 352, and finally the side surfaces of the two corresponding bonding plates 351 above and below are flush with the side surfaces of the pushing plate 34, so that the side surfaces of the bonding plate 351 and the side surfaces of the pushing plate 34 are simultaneously bonded to the side surfaces of the rectangular mold steel material, realizing surface contact clamping, so that the pushing plate 34 can stably push the rectangular mold steel material.

[0059] When the cross-section of the mold steel material is circular, the adjusting threaded rod 354 is rotated to drive the adjusting plate 353 to move toward the middle of the base 1, so that the adjusting plate 353 pushes the corresponding bonding plate 351 through the push-pull plate 352 to rotate to a position tangent to the circular mold steel material, that is, when the pushing plate 34 is against the outer surface of the circular mold steel material, the upper and lower bonding plates 351 are simultaneously bonded against the outer surface of the circular mold steel material, thereby increasing the clamping contact points for the circular mold steel material, so that the pushing plate 34 can stably push the circular mold steel material.

[0060] See also Figure 7 , Figure 8 and Fig. 9 A power assembly 37 for pushing the active plates 32 on both sides to move synchronously is provided on the position plate 31. The power assembly 37 includes a pushing hydraulic cylinder 371 fixedly installed on the left side of the position plate 31 away from the center of the base 1. The telescopic section of the pushing hydraulic cylinder 371 is fixedly connected to the active plate 32 on the left. The lower part of the active plate 32 is hinged with a hinged plate 372. A synchronous plate 373 is rotatably provided on the middle upper side of the base 1. The two ends of the synchronous plate 373 are respectively hinged to the hinged plates 372 on both sides.

[0061] After the position of the bonding plate 351 is adjusted, the extended section of the pushing hydraulic cylinder 371 is fully extended, so that the pushing hydraulic cylinder 371 drives the left active plate 32 to move to the right, and the left hinged plate 372 drives the synchronous plate 373 to rotate. The rotating synchronous plate 373 pulls the right hinged plate 372 to the left, and then the right hinged plate 372 drives the right active plate 32 to move to the left synchronously, so that the two active plates 32 are close to each other, and the active plate 32 drives the pushing plate 34 to move to the left and right sides of the mold steel material through the connecting plate 33.

[0062] Then, the hydraulic cylinder 371 is pushed to drive the two active plates 32 to continue to approach each other, so that the distance between the active plate 32 and the push plate 34 is reduced, so that the push plate 34 moves forward, and then the push plate 34 immediately drives the mold steel material forward after clamping the mold steel material, thereby improving the cutting efficiency.

[0063] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7A fixed column 4663 is fixedly installed on the upper part of the insertion card 4661, an L-shaped plate 466 is slidably arranged on the upper part of the movable roller frame 461 on the right side, and a push plate 4664 is slidably arranged on the front part of the transverse section of the L-shaped plate 4666, and an inclined surface for pushing the fixed column 4663 forward is provided on the side of the push plate 4664 close to the fixed column 4663, and the push plate 4664 is fixed in position by fastening screws, and a compression spring for pushing the L-shaped plate 4666 to the left is provided between the L-shaped plate 4666 and the movable roller frame 461 on the right side, and a passive push piece 4665 is fixedly installed on the rear side of one end of the push plate 4664 away from the fixed column 4663, and the passive push piece 4665 is located on the rear side of the push roller 462 on the right side.

[0064] When the movable roller frame 461 drives the push roller 462 to press against the side of the mold steel material, the operator moves the position of the push plate 4664 left and right so that the right side of the push plate 4664 presses against the fixed column 4663, and then the operator fixes the push plate 4664 and the L-shaped plate 4666 together by tightening the screws.

[0065] When the pushing plate 34 moves forward and contacts with the passive pushing piece 4665, the pushing plate 34 pushes the passive pushing piece 4665 to move to the right, so that the pushing plate 34 drives the pushing plate 4664 to move synchronously through the L-shaped plate 4666, so that the fixed column 4663 moves forward under the action of the inclined surface of the pushing plate 4664, and the fixed column 4663 drives the inserted card 4661 to move forward and exit the interior of the card tooth groove 4662, so that the movable roller frame 461 can move in a direction away from the center of the base 1.

[0066] It should be noted that the inclined surface on the push plate 4664 is gradually inclined forward from right to left, so that when the push plate 4664 moves to the right, the push plate 4664 can push the fixed column 4663 forward. The push plate 34 is provided with an inclined surface that gradually moves away from the center direction of the base from front to back. When the push plate 34 contacts the passive push piece 4665 through the inclined surface thereon, the push plate 34 can push the passive push piece 4665 away from the center direction of the base.

[0067] After that, the pushing plate 34 continues to move forward. Under the limitation of the pushing plate 4664 on the fixed column 4663, the inserted clamp 4661 remains separated from the inside of the clamping groove 4662, thereby preventing the pushing roller 462 from hindering the movement of the pushing plate 34. When the pushing plate 34 moves forward to the farthest position, the pushing plate 34 completes the fixed-length pushing of the mold steel material, and then drives the cutting saw 2 to move to the right through the electric slider, and the cutting saw 2 starts to cut the mold steel material.

[0068] See also Figure 7 , Fig. 9 and Fig.11A control component 36 is provided on the active plate 32 to prevent the push plate 34 from driving the mold steel material to move back and forth. The control component 36 includes a moving frame 361 that is slidably arranged on the upper side of the active plate 32. A follower column 362 is fixedly installed on the upper end of the rear part of the push plate 34 away from the center of the base 1. The follower column 362 is slidably inserted in the lower part of the moving frame 361.

[0069] When the push plate 34 moves forward, the push plate 34 drives the follower column 362 to move forward synchronously, and the follower column 362 drives the moving frame 361 to move forward synchronously. At the same time, the active plate 32 drives the moving frame 361 to move along the follower column 362 toward the center of the base 1.

[0070] Continue reading Figure 7 , Fig. 9 and Fig.11 A return portion 364 is provided on the active plate 32 to push the push plate 34 to move. The return portion 364 includes a sliding block 3641 that is slidably arranged on the lower side of the active plate 32. An insertion column 3642 is fixedly installed on the rear lower end of the push plate 34 away from the center of the base 1. The insertion column 3642 slides left and right and is inserted into the middle of the sliding block 3641. A pushing spring is provided between the push plate 34 and the corresponding sliding block 3641.

[0071] When the push plate 34 moves forward, the push plate 34 drives the sliding block 3641 to move forward synchronously through the insertion column 3642, and at the same time, the active plate 32 drives the sliding block 3641 to gradually approach the push plate 34 and compress the push spring.

[0072] See also Fig. 9 , Fig.11 and Fig.12 A slip limiting portion 363 for controlling the sliding of the follower column 362 is provided on the movable frame 361, and the slip limiting portion 363 includes a driven rack 3631 fixedly installed on the upper part of the follower column 362, and a driving gear 3632 is rotatably provided on the upper part of the movable frame 361. The driving gear 3632 is located on the upper part of the driven rack 3631 and meshes with it. A toothed plate 3633 is coaxially fixedly installed on the front side of the driving gear 3632, and a toothed plug-in 3634 is provided on the front side of the movable frame 361 for sliding up and down, and a coil spring for pushing the toothed plug-in 3634 upward is provided between the toothed plug-in 3634 and the movable frame 361.

[0073] When the follower column 362 moves forward, the follower column 362 drives the driven rack 3631 to move forward synchronously, and at the same time, the active plate 32 drives the driving gear 3632 to move toward the center of the base 1 through the moving frame 361, so that the driving gear 3632 rotates under the engagement with the driven rack 3631, and the driving gear 3632 drives the toothed plate 3633 to rotate synchronously. At the same time, the tooth plug-in 3634 is inserted into the toothed plate 3633 under the push of the coil spring, so that the toothed plate 3633 can only rotate in one direction, and the tooth plug-in 3634 and the toothed plate 3633 as a whole are equivalent to a ratchet and pawl mechanism.

[0074] When the push plate 34 moves forward to the maximum position, the telescopic section of the hydraulic cylinder 371 is contracted to drive the active plate 32 to move to the initial position, so that the active plate 32 moves in the direction away from the center of the base 1, and then the push spring has a tendency to push the push plate 34 away from the active plate 32 on the same side. However, at this time, the tooth plug-in 3634 clamps the tooth plate 3633, so that the tooth plate 3633 cannot be reversed, thereby making the active gear 3632 unable to rotate, and then the driven rack 3631 unable to move, resulting in the push plate 34 being unable to move away from the active plate 32, so that the active plate 32 drives the push plate 34 to move synchronously in the direction away from the center of the base 1, thereby making the push plate 34 disengage from the mold steel material, preventing the push plate 34 from abutting against the mold steel material. When the push plate 34 is pushed by the rebound force of the push spring, the push plate 34 drives the mold steel material to move backward, thereby ensuring the accuracy of the length of each movement of the mold steel material.

[0075] Continue reading Fig. 9 , Fig.11 and Fig.12 A slope is provided on the side of the latch tooth plug-in 3634 away from the center of the base 1 , and a slope push piece 3635 is fixedly installed on the side of the position plate 31 close to the center of the base 1 , and the slope push piece 3635 is used to push the latch tooth plug-in 3634 downward.

[0076] When the active plate 32 moves to the initial position, the inclined surface on the tooth plug-in 3634 contacts the inclined push piece 3635, so that the inclined push piece 3635 pushes the tooth plug-in 3634 downward, thereby causing the tooth plug-in 3634 to disengage from the tooth disk 3633, thereby allowing the tooth disk 3633 to rotate freely, and then the rebound force of the push spring pushes the push plate 34 back to the initial position.

[0077] When the present invention performs fixed-length cutting on the mold steel material, the following specific steps are performed: in the first step, the operator moves the mold steel material to the inside of the supporting circular plate 451, and then the operator manually rotates the rotating circular plate 455 so that the rotating wheel 453 of the rotating circular plate 455 is clamped against the side of the mold steel material, and then the operator cooperates with the transport equipment to move the mold steel material forward.

[0078] In the second step, the operator rotates the No. 2 threaded rod 411 to drive the two centering frames 43 closer to each other, so that the centering frame 43 drives the abutting wheels 44 thereon to clamp the mold steel material between them, so that the abutting wheels 44 can support and position the mold steel material, and the return spring drives the push roller 462 to abut on the left and right sides of the mold steel material.

[0079] The third step is to rotate the adjusting threaded rod 354 according to the cross-sectional shape of the mold steel material, so that the adjusting threaded rod 354 drives the fitting plate 351 to fit against the side of the mold steel material, thereby enabling the pushing plate 34 to stably push the mold steel material.

[0080] The fourth step is to fully extend the extended section of the pushing hydraulic cylinder 371, and the pushing hydraulic cylinder 371 drives the pushing plate 34 to move against the left and right sides of the mold steel material. Then, the pushing hydraulic cylinder 371 drives the two active plates 32 to continue to approach each other, so that the pushing plate 34 immediately drives the mold steel material forward after clamping the mold steel material, and then the mold steel material is cut by the cutting saw 2.

[0081] The fifth step is to retract the telescopic section of the hydraulic cylinder 371 to drive the active plate 32 to return to the initial position, so that the active plate 32 drives the push plate 34 to move synchronously in the direction away from the center of the base 1, thereby making the push plate 34 break away from contact with the mold steel material, and then the active plate 32 moves to the initial position, and the inclined push piece 3635 pushes the tooth plug-in 3634 downward, so that the push spring pushes the push plate 34 to return to the initial position.

[0082] In the sixth step, the fourth and fifth steps are repeated to continuously cut the mold steel material to a fixed length.

[0083] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
