Description

Technical Field

[0001] The invention relates to the technical field of bolt processing, in particular to cutting equipment for bolt production. Background Art

[0002] A bolt is a common fastener that connects two or more parts by fitting with a nut or screwing directly into a hole with an internal thread. Bolts are usually made by cutting, upsetting, and turning a bar. When cutting the bar, the bar is usually cut continuously according to the length of the bolt.

[0003] At present, when the rods are continuously cut, the conveying device is controlled to intermittently convey the rods to the corresponding position of the cutting device according to the length of the bolts, and then the cutting device is controlled to cut the rods, and a cutting groove is opened at the position corresponding to the cutting position on the cutting device, and then the cut rods are unloaded, and the above steps are repeated to achieve continuous cutting of the rods.

[0004] The following problems exist when the existing method is used to continuously cut the rods: 1. When the rods are continuously conveyed to the corresponding position of the cutting device, since the cut end of the rod may have burrs and other protrusions after one cutting, the protrusions at the end of the rod are easily stuck in the cutting groove to hinder the movement of the rod, and it is necessary to manually stop the machine and adjust the position of the rod, resulting in reduced cutting efficiency of the rod; 2. When cutting the rod, the cutting position of the rod cannot be accurately located, which affects the cutting accuracy. Since the cross-section of the rod is circular, when the cutting depth is close to the middle of the rod, the cutting device needs to spend a longer time to cut the rod, and there may be a problem of excessive feed amount in the process of cutting the rod, which causes more vibration and thermal deformation during the cutting process, further reducing the cutting accuracy of the rod.

[0029] 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 instructions shall be followed.

[0031] The present invention is used to cut a plurality of rods at the same time, and when the rods are moved to the cutting position, the present invention supports the rod portion located on the right side of the cutting position, thereby not interfering with the movement of the rods, thereby increasing the cutting efficiency of the rods, and at the same time the present invention can position the right end of the rod, thereby increasing the cutting accuracy of the rods.

[0032] Specifically, first, the adjusting device 3 is controlled to adjust the positions of the multiple supporting devices 4 according to the size of the rods, and then the external conveying device is controlled to intermittently convey the multiple rods to the right into the adjusting device 3, and then the supporting device 4 is controlled to support the rod part on the right side of the rod cutting position. At the same time, the supporting device 4 can position the right end of the rod according to the cutting length of the rod, and finally the cutting device 2 is controlled to cut the multiple rods at the same time. After the cutting of the rods is completed, the cut rods in the supporting device 4 are unloaded, and the supporting device 4 is controlled to return to the initial position, and then the external conveying device is controlled again to intermittently convey the multiple rods to the right into the adjusting device 3, and the above operations are repeated to achieve continuous cutting of multiple rods.

[0033] See also Figure 1-Figure 3 The adjusting device 3 includes two adjusting plates 31 symmetrically arranged front and back and slidably mounted on the upper end of the base 1. An adjusting plate 31 is also fixedly mounted in the middle of the upper end of the base 1. A guide plate 32 is fixedly mounted on the left side of the upper end of the adjusting plate 31. A V-shaped groove is provided on the upper end of the guide plate 32. A synchronization unit 33 for synchronously adjusting the positions of the two adjusting plates 31 is commonly installed between the left ends of the two adjusting plates 31 arranged front and back and the base 1.

[0034] The adjusting device 3 is used to adjust the spacing between multiple rods; specifically, first, according to the diameter of the rod, the synchronization unit 33 is controlled to drive the two adjusting plates 31 to move towards each other, and then the spacing between two adjacent rods is adjusted to ensure that the cutting device 2 can cut multiple rods at the same time, and when cutting thinner rods, the two rods located on the front and rear sides can be closer to the middle of the cutting device 2, so that the cutting device 2 can complete the cutting of the thinner rods faster, thereby increasing the cutting efficiency of the rods. The adjusting plate 31 drives its corresponding supporting device 4 to move, and then places the multiple rods in the corresponding V-grooves of the guide plates 32, and controls the external conveying device to drive the rods to move intermittently to the right along the V-grooves, so that the cutting point of the multiple rods can move to the right to the corresponding position of the cutting device 2.

[0035] See also Figure 3 The synchronization unit 33 includes a synchronization plate 331 of a telescopic structure hinged at the left ends of two adjustment plates 31 arranged front and rear, and the two synchronization plates 331 are arranged crosswise, and a central axis 332 is installed at the intersection of the two synchronization plates 331 for common rotation, and the lower end of the central axis 332 is fixedly connected to the base 1; a locking spring rod 333 is installed on the left end of the synchronization plate 331 for sliding up and down, and the locking spring rod 333 is located on the left side of the central axis 332, and a locking hole 11 is opened at the position of the upper end of the base 1 corresponding to the locking spring rod 333 to cooperate with the locking spring rod 333 to lock the synchronization plate 331.

[0036] The synchronization unit 33 is used to synchronously adjust the position of the two adjustment plates 31 arranged in the front and rear; specifically, first, the locking spring rod 333 is pulled out of the locking hole 11, and then the two synchronization plates 331 are pulled in the direction of approaching each other at the same time, so that the two synchronization plates 331 rotate in the direction of approaching each other with the central axis 332 as a reference, and then the two synchronization plates 331 drive the two adjustment plates 31 arranged in the front and rear to move in the direction of approaching each other, and the locking spring rod 333 is inserted into the corresponding locking hole 11 to achieve position locking of the synchronization plate 331, and then achieve synchronous position adjustment of the two adjustment plates 31 arranged in the front and rear, and the position of the synchronization plate 331 is quickly adjusted and locked by pulling out and inserting the locking spring rod 333, and then when it is necessary to cut bars of different sizes, the position of the adjustment plate 31 can be quickly adjusted and locked, further increasing the cutting efficiency of the bars.

[0037] See also Figure 2 and Figure 3 An L-shaped plate 315 is fixedly installed on the back-to-back right ends of the two adjustment plates 31 arranged front and back, and a matching spring rod 316 is slidably installed on the right end of the transverse section of the L-shaped plate 315 up and down. A plurality of matching holes evenly arranged front and back are opened at the upper end of the base 1 corresponding to the matching spring rod 316, and the matching holes are used to cooperate with the matching spring rod 316 to lock the position of the L-shaped plate 315.

[0038] When it is necessary to adjust the position of the two adjustment plates 31 arranged in front and behind, first pull the matching spring rod 316 out of the matching hole. When the position adjustment of the two adjustment plates 31 arranged in front and behind is completed, insert the matching spring rod 316 into the corresponding matching hole, and then make the matching spring rod 316 and the matching hole cooperate to lock the position of the L-shaped plate 315, so that the position of the adjustment plate 31 can also be locked by the matching spring rod 316 and the matching hole, thereby increasing the stability when cutting multiple bars.

[0039] See also Figure 1 , Figure 4-Figure 6The supporting device 4 includes a U-shaped frame 41 fixedly mounted on the right side of the upper end of the adjusting plate 31. A transmission plate 43 of a U-shaped structure is mounted on the right inner wall of the U-shaped frame 41 through an active unit 42. The active unit 42 is used to drive the transmission plate 43 to move left and right. Two square plates 45 arranged symmetrically front and back are slidably mounted on the lower end of the right inner wall of the transmission plate 43 through a top extension spring 44. A supporting plate 46 is fixedly mounted on the left side of the upper end of the square plate 45, and the two supporting plates 46 are contacted. The upper opposite sides of the two supporting plates 46 are provided with inclined surfaces. The transmission plate 43 is moved forward and backward. A positioning unit 47 for positioning the right end of the steel bar is installed on the right side of the inner wall; the active unit 42 includes a buffer block 421 slidably installed in the middle of the right end of the transmission plate 43, and the right end of the buffer block 421 is fixedly connected to the telescopic end of the electric push rod 422 fixedly installed on the right inner wall of the U-shaped frame 41; the front and rear inner walls of the U-shaped frame 41 are provided with a plurality of inclined grooves 411 evenly arranged on the left and right, and the left end of the inclined groove 411 is arranged to tilt upward, and a round rod 412 is slidably installed in the inclined groove 411, and the round rod 412 is fixedly connected to the transmission plate 43.

[0040] The supporting device 4 is used to support the part of the rod located on the right side of the cutting position after the rod moves to the cutting position, and the active unit 42 is used to drive the transmission plate 43 to move left and right; specifically, when the positions of the two adjustment plates 31 arranged in front and behind are adjusted synchronously, the adjustment plate 31 finally drives its corresponding two support plates 46 to move synchronously through the U-shaped frame 41, so that the inclined surfaces of the two support plates 46 can always correspond to the V-groove position of the guide plate 32.

[0041] When the external conveying device is controlled to drive the cutting point of the rod to move intermittently to the right along the V-shaped groove to the corresponding position of the cutting device 2, the electric push rod 422 is controlled to drive the transmission plate 43 to move to the left through the buffer block 421. At the same time, the transmission plate 43 moves upward under the cooperation of the round rod 412 and the inclined groove 411, so that the transmission plate 43 drives the support plate 46 to move to the left and move upward at the same time through the square plate 45, so that the inclined surfaces of the two support plates 46 can support the part on the right side of the cutting point of the rod, thereby increasing the stability of the rod during cutting. At the same time, the transmission plate 43 drives the positioning unit 47 to position the right end of the rod, thereby increasing the cutting accuracy of the rod.

[0042] When the cutting of the rod is completed, the electric push rod 422 is controlled to drive the transmission plate 43 to move to the right to the initial position through the buffer block 421. At the same time, the transmission plate 43 moves downward under the cooperation of the round rod 412 and the inclined groove 411, so that the transmission plate 43 drives the support plate 46 to move to the right and move downward through the square plate 45. Then, when the external conveying device is controlled to drive the cutting part of the rod to move intermittently to the right along the V-shaped groove to the corresponding position of the cutting device 2 again, the support plate 46 will not interfere with the movement of the rod, thereby increasing the cutting efficiency of the rod. When the rod needs to be cut again, the above steps are repeated to achieve continuous cutting of the rod.

[0043] See also Figure 5 and Figure 7 The positioning unit 47 includes a positioning plate 471 which is slidably installed on the opposite sides of the front and rear inner walls of the transmission plate 43. An adjusting screw 472 is installed at the front end of the positioning plate 471 by threaded fitting, and the adjusting screw 472 is rotatably connected to the transmission plate 43. A triangular plate 473 is fixedly installed at the middle part of the lower end of the positioning plate 471, and the triangular plate 473 is arranged in contact with the inclined surfaces of the two support plates 46.

[0044] The positioning unit 47 is used to position the right end of the rod; specifically, first, the adjusting screw 472 is screwed according to the cutting length of the rod to drive the positioning plate 471 to move to the left, so that the positioning plate 471 drives the triangular plate 473 to move to the left, and when the transmission plate 43 moves to the left and upward, the positioning plate 471 moves to the left and upward synchronously, and then when the two support plates 46 support the part on the right side of the rod cutting, the positioning plate 471 and the triangular plate 473 can push the right end of the rod to the left, ensuring that the right end of the rod rests against the left end of the positioning plate 471 and the triangular plate 473, preventing a small gap between the right end of the rod and the left end of the positioning plate 471 and the triangular plate 473 from affecting the cutting accuracy, thereby achieving precise positioning of the right end of the rod and increasing the cutting accuracy of the rod.

[0045] See also Figure 4 and Figure 5 A U-shaped connecting frame 311 is fixedly installed at the position of the upper end of the adjusting plate 31 corresponding to the right end of the guide plate 32, and a connecting frame 311 is also fixedly installed on the left side of the upper end of the U-shaped frame 41. A clamping block 313 is installed on the inner wall of the connecting frame 311 through an electric telescopic rod 312. A V-shaped clamping groove is provided at the lower end of the clamping block 313. A matching plate 314 is fixedly installed on the right end of the right clamping block 313. L-shaped separation plates 461 are fixedly installed on the upper ends of the two support plates 46, and the lower ends of the opposite sides of the two separation plates 461 are arranged as inclined surfaces for matching with the matching plate 314.

[0046] See also Figure 5 and Figure 7 A plurality of support rods 451 evenly arranged on the left and right are fixedly installed on the back sides of the two square plates 45. The ends of the support rods 451 away from the square plates 45 slide forward and backward and penetrate the transmission plate 43. An L-shaped material discharge trough 317 is provided at the upper end of the adjustment plate 31 corresponding to the positions of the two support plates 46. The right end of the lower inner wall of the transverse section of the material discharge trough 317 is tilted downward, and the right end of the transverse section of the material discharge trough 317 penetrates the adjustment plate 31.

[0047] See also Figure 7 and Figure 8, circular holes are provided at the right ends of the two support plates 46, and a connecting plate 432 is slidably installed on the lower end of the right inner wall of the transmission plate 43 through a plurality of connecting spring rods 431, and a locking rod 433 for cooperating with the circular hole to lock the position of the support plate 46 is fixedly installed at the position corresponding to the circular hole on the left end of the connecting plate 432, and an unlocking plate 434 with an L-shaped structure is fixedly installed on the upper end of the connecting plate 432, and the left side of the lower end of the transverse section of the unlocking plate 434 is set as an inclined surface for cooperating with the matching plate 314 to drive the connecting plate 432 to move to the right.

[0048] Initially, the locking rod 433 can be inserted into the circular hole, thereby locking the position of the support plate 46, so that the two support plates 46 can stably support the rod. Before cutting the rod, the electric telescopic rod 312 is controlled to drive the clamping block 313 to move downward and clamp on the upper end of the rod, so that the clamping groove of the clamping block 313 on the left and the V-shaped groove of the guide plate 32 cooperate to clamp and fix the left end of the rod cutting, and the clamping groove of the clamping block 313 on the right and the inclined surfaces of the two support plates 46 cooperate to clamp and fix the right end of the rod cutting, thereby increasing the stability during rod cutting. At the same time, the square plate 45 enables the two support plates 46 to stably support the rod under the action of multiple support rods 451.

[0049] When the two support plates 46 support the right side of the rod cutting, the separation plate 461 moves to the corresponding position of the matching plate 314. When the rod cutting is completed, the electric telescopic rod 312 is controlled to drive the clamping block 313 to return to the initial position upward, so that the clamping block 313 no longer clamps and fixes the rod. Then, the right electric telescopic rod 312 is controlled to drive the right clamping block 313 to continue to move upward, so that the right clamping block 313 drives the matching plate 314 to move upward, so that the matching plate 314 can first cooperate with the inclined surface of the unlocking plate 434 to drive the connecting plate 432 to move to the right and compress the connecting spring rod 431, so that the connecting plate 432 drives the locking rod 433 to move out of the round hole, thereby releasing the lock of the two support plates 46.

[0050] Then, the matching plate 314 and the two separation plates 461 cooperate with each other to drive the two support plates 46 to move away from each other, and the matching plate 314 is always in contact with the left end of the unlocking plate 434, so that the locking rod 433 will not be inserted into the round hole, so that the two support plates 46 are always in an unlocked state, and the support plate 46 drives the two square plates 45 to move away from each other and compress the extension spring 44, so that the cut rods move downward along the inclined surfaces of the two support plates 46 under the action of gravity and fall into the feed trough 317, and move out of the adjustment plate 31 to the right along the lower inner wall of the feed trough 317, so as to realize the feeding of the rods, and the rods can always be arranged horizontally under the action of the two support plates 46, so as to facilitate the collection and subsequent processing of the cut rods, thereby increasing the processing efficiency of the bolts.

[0051] When the bar material is unloaded, the right electric telescopic rod 312 is controlled to drive the right clamping block 313 to return to its initial position downward, so that the matching plate 314, the unlocking plate 434 and the separation plate 461 are separated, and then the square plate 45 drives the two support plates 46 to return to their initial positions under the action of the top extension spring 44. At the same time, the connecting plate 432 drives the locking rod 433 to be inserted into the round hole again under the action of the connecting spring rod 431, so as to lock the position of the support plate 46.

[0053] It should be noted that the buffer 24 in the present invention is a hydraulic buffer, which can buffer between the lower pressure plate 23 and the buffer 24 .

[0054] The cutting device 2 is used to cut the rods; specifically, the hydraulic push rod 22 is controlled to finally drive the cutter 26 to move downward through the lower pressure plate 23, and the cutter 26 is started so that the cutter 26 cuts the rods while moving downward. When the feed amount of the cutter 26 is too large, the cutter 26 can drive the buffer 24 to be compressed through the buffer plate 25 under the blocking effect of the rods, so that when the cutter 26 cuts different positions of the rods, the rods can be cut with an appropriate feed amount, thereby reducing the vibration and deformation of the cutter 26 during the cutting process, thereby further improving the cutting accuracy.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
