Description

Technical Field

[0001] The present invention relates to the field of steel cutting equipment, and specifically to a fixed-length cutting equipment for die steel. Background Art

[0002] Die steel is the steel used to manufacture 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, the accuracy, output and production cost of products.

[0003] Die steel materials are usually in the shape of rectangular long strips or rods. During the processing of die steel, it is necessary to cut the die steel materials into several die steel blanks with a fixed length to facilitate the subsequent processing of the die steel blanks into dies. In the prior art, when performing fixed-length cutting on die steel materials, a fully automatic high-speed circular saw cutting machine is usually used for fully automatic fixed-length cutting of die steel. The circular saw cutting machine drives a clamping structure to clamp the die steel material through a hydraulic cylinder, and then drives the clamping structure to intermittently move through a lead screw, so as to realize fixed-length pushing of the die steel material. The feed amount of the die steel material pushed each time is controlled by controlling the angle of each intermittent rotation of the lead screw.

[0004] However, when the existing circular saw cutting machine cuts a relatively long die steel material, since the length of the die steel material is relatively long, the lead screw needs to drive the clamping structure to reciprocate, so that the clamping structure can continuously perform fixed-length pushing on the relatively long die steel material. However, when the clamping structure returns to its position, the bottom plate of the clamping structure will rub against the bottom surface of the die steel material, thereby causing wear on the bottom surface of the die steel and affecting the cutting effect of the die steel material. In addition, the method of driving the clamping structure to clamp and push the die steel material through a lead screw can only drive the die steel material to be pushed after the clamping structure clamps the die steel material, so that there is an interval between the clamping and pushing actions, thereby reducing the pushing efficiency and affecting the cutting efficiency.

The two threaded sections of the second threaded rod are respectively threadedly connected with two centering frames.

[0020] The beneficial effects of the present invention are as follows:

[0021] First, the positioning mechanism adopted by the present invention contacts the die steel material in the form of rolling contact, and the rolling contact points are evenly distributed in the four directions of up, down, left, and right of the die steel material, thereby preventing the positioning mechanism from having sliding friction with the die steel material, resulting in wear of the die steel material, ensuring the cutting effect and cutting accuracy of the die steel material, and controlling the push plate not to contact the die steel material during the reset movement through the control component. On the one hand, it avoids the push plate driving the die steel material to move during the reset movement and affecting the pushing accuracy of the die steel material. On the other hand, it avoids sliding friction between the push plate and the die steel material, thereby further ensuring the cutting effect and accuracy.

[0022] Second, the power component adopted by the present invention drives the two active plates to approach each other synchronously, so that the active plates drive the push plate through the connecting plate to clamp the die steel material on both left and right sides. Then, the power component continues to drive the two active plates to approach each other, so that the active plates push the die steel material forward through the push plate, thereby realizing fixed-length pushing of the die steel material immediately after clamping, coherently connecting the clamping and pushing operations, and thus removing the interval waiting between clamping and pushing, and improving the cutting efficiency of the die steel material.

[0023] Third, the auxiliary clamping component adopted by the present invention can avoid the position of the push plate, thereby preventing the auxiliary clamping component from hindering the movement of the push plate, so as to ensure that the push plate can stably push the die steel material. In addition, by rotating the first bidirectional screw rod, the distance between the two position plates can be adjusted, thereby changing the pushing distance of the push plate on the die steel material, so as to adapt to different cutting length requirements.

[0024] IV. The push rod assembly adopted by the present invention has the function of adjusting the clamping contact method according to the shape of the die steel material. When dealing with rectangular die steel materials, a multi-faceted contact clamping method is adopted; when dealing with rod-shaped die steel materials, a circumferential tangent contact clamping method is adopted. By matching different clamping contact methods with different shapes of die steel materials, the pushing plate can push the die steel material more stably, thereby avoiding the phenomenon of slipping friction and ensuring the accuracy of pushing.

Detailed implementation manners

[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 a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in the field or according to the product specifications.

[0040] Refer to Figure 1 、 Figure 2 and Figure 7 , a fixed-length cutting device for die steel, comprising a base 1. On the front side of the base 1, support members 11 are symmetrically and fixedly installed on the left and right. On the upper side of the front part of the left support member 11, a cutting saw 2 is slidably arranged left and right through an electric slider (not shown in the figure). A pushing mechanism 3 for pushing the die steel material with a fixed length is arranged in the middle of the base 1, and a positioning mechanism 4 for centering and clamping the die steel material is arranged on the base 1.

[0041] When it is necessary to cut die steel materials, first, the operator places the die steel materials inside the positioning mechanism 4. The positioning mechanism 4 clamps and positions the die steel materials at the middle position of the pushing mechanism 3. Then, the pushing mechanism 3 pushes the die steel materials for a fixed length, and then the cutting saw 2 cuts the die steel materials for a fixed length.

[0042] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the positioning mechanism 4 includes bracket members 41 that are symmetrically arranged left and right and fixedly installed at the rear side of the base 1. A limiting component 45 for continuously clamping the die steel materials is arranged at the rear side of the bracket members 41. The limiting component 45 includes a supporting circular plate 451 that is fixedly installed at the rear sides of the two bracket members 41 together. Clamping frames 452 that slide radially along the circumferential direction of the supporting circular plate 451 are arranged at equal intervals at 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. A driving column 454 is fixedly installed at the front side of the clamping frame 452. A rotating circular plate 455 is rotatably arranged at the front side of the supporting circular plate 451. Spiral grooves 456 are arranged at equal intervals along the circumferential direction of the rotating circular plate 455. The driving column 454 slides inside the corresponding spiral groove 456.

[0043] When it is necessary to position the die steel materials, the operator moves the die steel materials to the rear side of the supporting circular plate 451 through an existing lifting device. Then, the operator assists the lifting equipment to insert one end of the die steel materials into the inside 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 driving column 454 to move radially along the supporting circular plate 451 through the spiral groove 456 on it. Thus, the driving column 454 drives the rotating wheel 453 through the clamping frame 452 to abut and clamp on the side surface of the die steel materials, thereby initially positioning the die steel materials. Then, the operator cooperates with the lifting equipment to move the die steel materials forward.

[0044] It should be noted that a number of positioning holes are arranged at equal intervals along the circumferential direction of the rotating circular plate 455. A positioning pin rod is slidably arranged on the supporting circular plate 451. After the operator drives the rotating wheel 453 to abut and clamp on the side surface of the die steel materials through the rotating circular plate 455, the operator moves the positioning pin rod forward, so that the positioning pin rod penetrates through 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] Refer to Figure 1 、 Figure 2 and Figure 4, on the left side, a guide post 42 is fixedly installed on both the support member 41 and the side of the support member 11 close to the center of the base 1. Symmetrically arranged up and down on the guide post 42 is a centering frame 43 that slides jointly. On the side of the centering frame 43 close to each other, a number of abutting wheels 44 are rotatably arranged in the front-back direction. On the right side of the support member 41, a second threaded rod 411 is rotatably arranged, and the two threaded sections of the second threaded rod 411 are respectively threadedly connected to the two centering frames 43.

[0046] When the die steel material moves forward between the centering frames 43, the operator rotates the second threaded rod 411 to drive the two centering frames 43 closer to each other, so that the centering frames 43 drive the abutting wheels 44 thereon to clamp the die steel material, enabling the abutting wheels 44 to support and position the die steel material.

[0047] Refer to Figure 1 、 Figure 2 and Figure 5 , on the support member 11, there is an auxiliary clamping assembly 46 for limiting the position of the die steel material close to the cutting saw 2. The auxiliary clamping assembly 46 includes moving roller frames 461 that are symmetric left and right and slide left and right on the front side of the support member 11. Between the left moving roller frame 461 and the left support member 11, there is a return spring that pushes the left moving roller frame 461 to the right. On the side of the moving roller frame 461 close to the middle of the base 1, a pushing roller 462 is rotatably arranged. At the upper part of the moving roller frame 461, a linkage plate 463 is hinged. At the upper part of the two front guide posts 42, a fixing plate 464 is fixedly installed. At the rear side of the fixing plate 464, a rotating plate 465 is rotatably arranged, and the left and right ends of the rotating plate 465 are respectively hinged to the corresponding linkage plates 463.

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

[0049] Refer to Figure 2 、 Figure 5 and Figure 6, a reverse stop portion 466 for preventing the accidental sliding of the moving roller frame 461 is provided on the right support member 11. The reverse stop portion 466 includes an insertion card member 4661 that slides back and forth on the upper part of the right support member 11. A plurality of card tooth grooves 4662 are equidistantly formed in the front side of the upper part of the moving roller frame 461 on the right in the left - right direction. A driving spring for pushing the insertion card member 4661 backward is provided between the insertion card member 4661 and the right support member 11.

[0050] Before the die steel material moves to the position of the moving roller frame 461, the operator needs to manually pull the insertion card member 4661 forward so that the insertion card member 4661 withdraws from the inside of the card tooth groove 4662, so that the moving roller frame 461 on the right can slide left and right. Then the operator pulls the moving roller frame 461 in a direction away from the middle of the base 1, so that the moving roller frames 461 can move away from each other. The moving roller frame 461 on the left compresses the return spring, thus facilitating the movement of the die steel material between the moving roller frames 461.

[0051] When the die steel material is between the moving roller frames 461, release the moving roller frame 461 on the left. When the moving roller frame 461 on the left moves to the right under the pushing force of the return spring of the return spring, remove the external force on the insertion card member 4661, so that the driving spring pushes the insertion card member 4661 to insert into the corresponding card tooth groove 4662. When the moving roller frame 461 on the right moves to the left, the insertion card member 4661 can contact the inclined surface of the card tooth groove 4662. The insertion card member 4661 moves forward under the action of the inclined surface and compresses the driving spring, so that the insertion card member 4661 does not hinder the moving roller frame 461 from moving in the direction close to the middle of the base 1, that is, moving to the left.

[0052] The right - ward movement of the card tooth groove 4662 is hindered by the flat - surface cooperation between the insertion card member 4661 and the card tooth groove 4662, thereby restricting the movement of the moving roller frame 461, so that the moving roller frame 461 can drive the pushing roller 462 to stably clamp and position the front part of the die steel material.

[0053] Refer to Figure 1 、 Figure 7 and Figure 8 , the pushing mechanism 3 includes position plates 31 that are symmetric left - right and slide left - right on the upper side of the base 1. A first bidirectional screw 12 is rotatably provided on the upper part of the base 1. The two threaded sections of the first bidirectional screw 12 are respectively threadedly connected to the two position plates 31.

[0054] The operator rotates the first bidirectional screw 12 as needed, so that the first bidirectional screw 12 drives the two position plates 31 to approach or move away from each other, thereby adjusting the pushing distance of the die steel each time. When it is necessary to increase the pushing length of the die steel each time, the operator rotates the first bidirectional screw 12 to drive the two position plates 31 to approach each other. Conversely, it drives the two position plates 31 to move away from each other.

[0055] Refer to Figure 1 、 Figure 7 and Figure 9 As shown in, on one side of the position plate 31 close to the center of the base 1, a driving plate 32 is slidably arranged left and right. On one side of the driving plate 32 close to the center of the base 1, two connecting plates 33 are hinged. The two connecting plates 33 are arranged front and back on the driving plate 32. On one side of the two connecting plates 33 facing each other front and back and close to the center of the base 1, a pushing plate 34 is jointly hinged. The driving plate 32, the two connecting plates 33 and the pushing plate 34 form a parallelogram structure.

[0056] Since the driving plate 32, the two connecting plates 33 and the pushing plate 34 form a parallelogram structure, the driving plate 32 and the pushing plate 34 are always parallel to each other. Also, since the driving plate 32 is in a posture parallel to the die steel material, the pushing plate 34 is also always parallel to the die steel material. When the distance between the driving plate 32 and the pushing plate 34 decreases, due to the fact that the length of the connecting plate 33 cannot change, one end of the connecting plate 33 close to the middle of the base 1 gradually moves forward relatively, and then the connecting plate 33 drives the pushing plate 34 to move forward. The pushing plate 34 and the driving plate 32 change from the original state of being opposite left and right to a state of being staggered left and right.

[0057] Refer to Figure 7 、 Figure 9 and Figure 10 As shown in, on the pushing plate 34, a push rod assembly 35 for assisting in pushing the rod-shaped material is arranged. The push rod assembly 35 includes fitting plates 351 that are symmetrically arranged up and down and hinged on one side of the pushing plate 34 close to the center of the base 1. In the middle of the side of the fitting plate 351 away from the center of the base 1, a push-pull plate 352 is hinged. At one end of the push-pull plates 352 at the same pushing plate 34 away from the center of the base 1, an adjusting plate 353 is jointly hinged. On one side of the pushing plate 34 away from the center of the base 1, an adjusting threaded rod 354 is rotatably arranged. The adjusting threaded rod 354 is threadedly connected to the adjusting plate 353.

[0058] When the cross-section of the die steel material is rectangular, rotating the adjusting threaded rod 354 drives the adjusting plate 353 to move away from the middle of the base 1, so that the adjusting plate 353 pulls the corresponding fitting plate 351 to rotate through the push-pull plate 352. Finally, the sides of the two fitting plates 351 corresponding up and down are flush with the side of the pushing plate 34, so that the sides of the fitting plate 351 and the side of the pushing plate 34 are simultaneously attached to the side of the rectangular die steel material, realizing surface-contact clamping. Furthermore, the pushing plate 34 can stably push the rectangular die steel material.

[0059] When the cross-section of the die steel material is circular, rotate the adjusting screw rod 354 to drive the adjusting plate 353 to move towards the middle of the base 1, so that the adjusting plate 353 drives the corresponding fitting plate 351 at the corresponding position to rotate to a position tangent to the circular die steel material through the push-pull plate 352, that is, when the push plate 34 abuts against the outer side of the circular die steel material, the upper and lower fitting plates 351 simultaneously abut against the outer side of the circular die steel material, thereby increasing the clamping contact points of the circular die steel material, enabling the push plate 34 to stably push the circular die steel material.

[0060] Refer to Figure 7 、 Figure 8 and Figure 9 As shown in, a power assembly 37 for driving the active plates 32 on both sides to move synchronously is arranged on the position plate 31. The power assembly 37 includes a push hydraulic cylinder 371 fixedly installed on the side of the left position plate 31 away from the center of the base 1. The telescopic section of the push hydraulic cylinder 371 is fixedly connected to the left active plate 32. A hinge plate 372 is hinged to the lower part of the active plate 32. A synchronous plate 373 is rotatably arranged on the upper side of the middle of the base 1. Both ends of the synchronous plate 373 are respectively hinged to the hinge plates 372 on both sides.

[0061] After adjusting the position of the fitting plate 351, fully extend the telescopic section of the push hydraulic cylinder 371, so that the push hydraulic cylinder 371 drives the left active plate 32 to move to the right. The left hinge plate 372 pushes the synchronous plate 373 to rotate. The rotating synchronous plate 373 pulls the right hinge plate 372 to the left, and then the right hinge plate 372 drives the right active plate 32 to move to the left synchronously, so that the two active plates 32 approach each other. The active plate 32 drives the push plate 34 to move to abut against the left and right sides of the die steel material through the connecting plate 33.

[0062] After that, the push hydraulic cylinder 371 drives the two active plates 32 to continue approaching each other, so that the distance between the active plate 32 and the push plate 34 decreases, so that the push plate 34 moves forward, and then the push plate 34 drives the die steel material to be pushed forward immediately after clamping the die steel material, thereby improving the cutting efficiency.

[0063] Refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7, a fixing column 4663 is fixedly installed on the upper part of the inserted card member 4661. An L-shaped plate 4666 is slidably arranged left and right on the upper part of the moving roller frame 461 on the right side. A pushing plate 4664 is slidably arranged left and right at the front part of the horizontal section of the L-shaped plate 4666. An inclined surface for pushing the fixing column 4663 forward is formed on the side of the pushing plate 4664 close to the fixing column 4663. The position of the pushing plate 4664 is fixed by fastening screws. A compression spring for pushing the L-shaped plate 4666 to the left side is arranged between the L-shaped plate 4666 and the moving roller frame 461 on the right side. A passive pushing member 4665 is fixedly installed at the rear side of the end of the pushing plate 4664 away from the fixing column 4663. The passive pushing member 4665 is located at the rear side of the pushing roller 462 on the right side.

[0064] When the moving roller frame 461 drives the pushing roller 462 to abut against the side of the die steel material, the operator moves the position of the pushing plate 4664 left and right, so that the right side of the pushing plate 4664 abuts against the fixing column 4663. Then, the operator fixes the pushing plate 4664 and the L-shaped plate 4666 together through the fastening screws.

[0065] When the pushing plate 34 moves forward to contact with the passive pushing member 4665, the pushing plate 34 pushes the passive pushing member 4665 to move to the right side, so that the pushing plate 34 drives the pushing plate 4664 to move synchronously through the L-shaped plate 4666, thereby enabling the fixing column 4663 to move forward under the action of the inclined surface of the pushing plate 4664. The fixing column 4663 drives the inserted card member 4661 to move forward and withdraw from the inside of the card tooth groove 4662, so that the moving 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 pushing plate 4664 has a structure that gradually inclines forward from right to left, so that when the pushing plate 4664 moves to the right side, the pushing plate 4664 can push the fixing column 4663 forward. The pushing plate 34 is provided with an inclined surface that gradually moves away from the center of the base in the front-to-back direction. When the pushing plate 34 contacts the passive pushing member 4665 through the inclined surface thereon, the pushing plate 34 can push the passive pushing member 4665 in a direction away from the center of the base.

[0067] Then the pushing plate 34 continues to move forward. Under the limitation of the pushing plate 4664 on the fixing column 4663, the inserted card member 4661 remains separated from the inside of the card tooth groove 4662, so as to prevent 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 die steel material. Then, the cutting saw 2 is driven by the electric slider to move to the right side, and the cutting saw 2 is started to cut the die steel material.

[0068] Refer to Figure 7 、 Figure 9 and Figure 11, a control component 36 for preventing the pushing plate 34 from driving the die steel material to move back and forth is arranged on the active plate 32. The control component 36 includes a moving frame 361 slidably arranged on the upper side of the active plate 32 in the front-back direction. A follower column 362 is fixedly installed at the upper rear end of the side of the pushing plate 34 away from the center of the base 1. The follower column 362 is slidably inserted through the lower part of the moving frame 361.

[0069] When the pushing plate 34 moves forward, the pushing plate 34 drives the follower column 362 to move forward synchronously. 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 in the direction close to the center of the base 1 along the follower column 362.

[0070] Continue to refer to Figure 7 、 Figure 9 and Figure 11 , a restoring part 364 for pushing the pushing plate 34 to move is arranged on the active plate 32. The restoring part 364 includes a sliding block 3641 slidably arranged on the lower side of the active plate 32 in the front-back direction. An insertion column 3642 is fixedly installed at the lower rear end of the side of the pushing plate 34 away from the center of the base 1. The insertion column 3642 is slidably inserted through the middle part of the sliding block 3641 in the left-right direction. A pushing spring is arranged between the pushing plate 34 and the corresponding sliding block 3641.

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

[0072] Refer to Figure 9 、 Figure 11 and Figure 12 , a slip limiting part 363 for controlling the sliding of the follower column 362 is arranged on the moving frame 361. The slip limiting part 363 includes a driven rack 3631 fixedly installed on the upper part of the follower column 362. A driving gear 3632 is rotatably arranged on the upper part of the moving frame 361. The driving gear 3632 is located above the driven rack 3631 and meshes with it. A tooth engaging disc 3633 is coaxially fixedly installed on the front side of the driving gear 3632. A tooth engaging plug 3634 is slidably arranged up and down on the front side of the moving frame 361. A spiral spring for pushing the tooth engaging plug 3634 upward is arranged between the tooth engaging plug 3634 and the moving frame 361.

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

[0074] After the pushing plate 34 moves forward to the maximum position, the telescopic section of the retracting push hydraulic cylinder 371 drives the active plate 32 to move to the initial position, so that the active plate 32 moves away from the center of the base 1. As a result, the pushing spring has a tendency to push the pushing plate 34 away from the active plate 32 on the same side. However, at this time, the tooth engaging insert 3634 locks the tooth engaging disc 3633, so that the tooth engaging disc 3633 cannot reverse, thus making the active gear 3632 unable to rotate, and further making the driven rack 3631 unable to move, resulting in the pushing plate 34 being unable to move away from the active plate 32. Then the active plate 32 drives the pushing plate 34 to move away from the center of the base 1 synchronously, so that the pushing plate 34 is disengaged from the contact with the die steel material. When the pushing plate 34 abuts against the die steel material, it is ensured that the pushing plate 34 does not drive the die steel material to move backward under the resilience of the pushing spring, ensuring the accuracy of the moving length of the die steel material each time.

[0075] Continue to refer to Figure 9 、 Figure 11 and Figure 12 On the side of the tooth engaging insert 3634 away from the center of the base 1, there is an inclined surface. On the side of the position plate 31 close to the center of the base 1, an inclined surface pusher 3635 is fixedly installed. The inclined surface pusher 3635 is used to push the tooth engaging insert 3634 downward.

[0076] When the active plate 32 moves to the initial position, the inclined surface on the tooth engaging insert 3634 contacts the inclined surface pusher 3635, so that the inclined surface pusher 3635 pushes the tooth engaging insert 3634 downward, thus making the tooth engaging insert 3634 disengage from the tooth engaging disc 3633. As a result, the tooth engaging disc 3633 can rotate freely. Then, the resilience of the pushing spring pushes the pushing plate 34 back to the initial position.

[0077] When the present invention performs fixed-length cutting on the die steel material, the following steps are specifically as follows: First step, the operator moves the die steel material into the support circular plate 451. Then, the operator manually rotates the rotating circular plate 455 so that the rotating wheel 453 of the rotating circular plate 455 abuts and clamps on the side of the die steel material. Then, the operator cooperates with the lifting equipment to move the die steel material forward.

[0078] In the second step, the operator rotates the second threaded rod 411 to drive the two centering frames 43 closer to each other, so that the centering frames 43 drive the abutting wheels 44 thereon to clamp the die steel material therebetween, enabling the abutting wheels 44 to support and position the die steel material, and the return spring drives the pushing rollers 462 to abut against the left and right sides of the die steel material.

[0079] In the third step, the adjusting threaded rod 354 is rotated according to the shape of the cross-section of the die steel material, so that the adjusting threaded rod 354 drives the fitting plate 351 to fit and abut against the side of the die steel material, thereby enabling the pushing plate 34 to stably push the die steel material.

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

[0081] In the fifth step, the telescopic section of the pushing hydraulic cylinder 371 is contracted to drive the active plate 32 to return to the initial position, so that the active plate 32 drives the pushing plate 34 to move synchronously away from the center of the base 1, thereby causing the pushing plate 34 to be disengaged from contact with the die steel material. Subsequently, the active plate 32 moves to the initial position, and the inclined surface pusher 3635 pushes the tooth engaging plug 3634 downward, so that the pushing spring drives the pushing plate 34 to return to the initial position.

[0082] In the sixth step, the fourth and fifth steps are repeated to continuously perform fixed-length cutting on the die steel material.

[0083] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
