Description

Technical Field

[0001] The invention relates to the technical field of cold forging of anchor bolts, in particular to a cold forging forming device for processing anchor bolts. Background Art

[0002] Anchor bolts, also known as expansion bolts or anchors, are fasteners used to secure objects to materials such as concrete, masonry, etc. They are widely used in the fields of construction and engineering to connect structural parts, such as fixing mechanical equipment, installing pipe supports, hanging systems, and various types of building components.

[0003] Cold heading is a metal forming process widely used in the fastener manufacturing industry, including the manufacture of anchor bolts. The cold heading process is to apply high pressure to the metal material at room temperature, so that the metal material flows through the mold and fills the mold cavity to form the desired shape and size. Compared with heat treatment, cold heading can maintain the good mechanical properties of the material, and can improve production efficiency and reduce material waste.

[0004] At present, the common practice is to use an anchor cold heading machine to cold forge the bar. Specifically, the cold heading machine applies a certain pressure to the metal blank at room temperature, causing it to undergo plastic deformation in the die cavity and be formed into the specified shape and size. First, the machine thickens the top of the blank by applying pressure to form a preliminary head shape; then, the blank is further subjected to pressure in the die, undergoing plastic deformation, gradually filling the die cavity, and finally forming the desired anchor shape, completing the cold heading of the anchor.

[0005] However, although the existing anchor cold forging machine can effectively cold forge bars into anchors, it has some shortcomings in actual use. Specifically, the punch head is connected to the moving die through bolts, and the punch head is easily damaged after long-term use. When it needs to be replaced, the machine must be stopped first, and then the bolts fixing the punch head must be removed one by one to release its connection with the moving die. When the new punch head is installed, the bolts must be tightened one by one to ensure a stable connection. This is not only time-consuming and labor-intensive, but also significantly reduces the overall processing efficiency. Summary of the invention

The number of each group of card slots 611 is two, and the two card slots 611 in each group are symmetrically arranged up and down. The movable mold 61 is provided with a pushing member for pushing the front and rear connecting frames 66 to move toward and away from each other. The pushing member includes a hydraulic cylinder 2 63 embedded on the left side of the movable mold 61. The hydraulic cylinder 2 63 is a double-piston rod hydraulic cylinder. The right piston rod of the hydraulic cylinder 2 63 is connected with left and right push blocks 64. A slide plate 65 located between two push blocks 64 is slidably connected to the right piston rod of the second pressure cylinder 63, an inclined groove 67 is opened on the L-shaped plate 661 of the connecting frame 66, and two front and rear push rods 68 are connected to the slide plate 65, and the two push rods 68 are respectively located in the inclined grooves 67 on the front and rear L-shaped plates 661.

A material receiving frame 12 is connected to the base 2 for collecting the punch head 62 sliding off the movable mold 61. The rear end of the material receiving frame 12 extends to the outside of the base 2. The top of the base 2 is separated from the front to the back by a through hole 13 located directly above the material receiving frame 12.The number of the movable mold 6, the fixed mold 7, the electric clamp 10 and the through-port 13 can be reasonably set according to the actual needs of the anchor cold heading process, and the number of the movable mold 6, the fixed mold 7, the electric clamp 10 and the through-port 13 is consistent.

[0035] See also Figure 1 , Figure 7 , Figure 8 and Fig. 9 A conveying mechanism for conveying the punch head 62 is provided on the base 2, and the conveying mechanism includes two connecting plates 140 respectively connected to the front and rear sides of the base 2, and a storage frame 141 located on the upper side of the movable mold 6 is connected between the upper parts of the two connecting plates 140, and the top and rear sides of the storage frame 141 are both open-type settings, and an electric wheel 142 is installed at intervals in the storage frame 141, and an outlet 147 is separated from the front to the back at the bottom of the storage frame 141. A plurality of groups of guide rods 143 are connected to the left outer wall of the storage frame 141 from the front to the back, and the number of each group of guide rods 143 is two, and the two guide rods 143 in each group are arranged front and back, and each group of guide rods 143 is slidably connected to a connecting plate 144, and each guide rod 143 is sleeved with a spring 145, and the two ends of the spring 145 are respectively connected to the guide rod 143 and the connecting plate 144. The plates 144 are connected, and each connecting plate 144 is rotatably connected to a blocking wheel 146 on the right side, and the blocking wheel 146 extends into the storage frame 141. The blocking wheel 146 corresponds to the outlet 147 one by one, and the blocking wheel 146 is located directly above the corresponding outlet 147. The number of connecting plates 144, blocking wheels 146 and outlets 147 can be reasonably set according to the actual needs of the anchor cold heading processing, and the number of connecting plates 144, blocking wheels 146 and outlets 147 is consistent with the number of movable molds 6. An electric push rod 148 is installed on the right side of the bottom of the movable mold 61, and a support block 149 for supporting the punching head 62 is connected to the telescopic rod of the electric push rod 148. An L-shaped pull plate 15 is connected to the left side of each connecting plate 144, and the left piston rod on the hydraulic cylinder 63 is in contact with the pull plate 15 on the same side as it.

[0036] The hydraulic cylinder 11 is controlled to work to drive the movable mounting frame 4 to drive the movable die 6 to move back and forth to the right and left. The movable die 6 cooperates with the fixed die 7 to the right to perform cold heading operation on the bar. While the movable die 6 retreats to the left, the right piston rod of the hydraulic cylinder 2 63 is controlled to extend to push the workpiece out of the punch head 62 to prevent the workpiece from being stuck on the punch head 62. Subsequently, the right piston rod of hydraulic cylinder 2 63 is controlled to retract. In the process of the right piston rod of hydraulic cylinder 2 63 ejecting the workpiece on the punch head 62, the distance extended by the right piston rod of hydraulic cylinder 2 63 is less than the distance between the left push block 64 and the slide plate 65. Therefore, the left push block 64 follows the right piston rod of hydraulic cylinder 2 63 to move to the right and will not push the slide plate 65 to move, thereby ensuring that the workpiece is smoothly ejected from the punch head 62. Therefore, when the right piston rod of hydraulic cylinder 2 63 retracts and drives the right push block 64 to move to the left, it will not push the slide plate 65 to move, thereby ensuring that the punch head 62 is firmly locked on the right side of the movable mold 61, thereby ensuring that the cold heading operation of the workpiece is carried out smoothly. After the movable mold 6 retreats to the left, the piston rod of the hydraulic cylinder 3 72 is controlled to extend and retract. When the piston rod of the hydraulic cylinder 3 72 is extended, the workpiece can be pushed out to the left from the fixed mold 71. Then, the electric clamp 10 is controlled to clamp the workpiece pushed out from the fixed mold 71. Then, the linear motor 8 is controlled to drive the movable frame 9 to drive the electric clamp 10 to move backward, so as to move the workpiece backward to align with the next fixed mold 7 for secondary cold heading operation. When the punch head 62 of the movable mold 6 moves to the right to contact the workpiece, the electric clamp 10 is controlled to release the workpiece so that the punch head 62 of the movable mold 6 can push the workpiece into the fixed mold 71 of the fixed mold 7 for cold heading. When the movable mold 6 retreats to the left, the linear motor 8 is controlled to drive the movable frame 9 to drive the electric clamp 10 to move forward to clamp the workpiece pushed out from the fixed mold 71 later.

[0037] Put the new punch head 62 into the storage frame 141 from the rear side of the storage frame 141, control the electric wheel 142 to work, and convey the new punch head 62 forward to align with the outlet 147. The blocking wheel 146 can block the punch head 62 to prevent the punch head 62 from falling directly downward from the outlet 147. When the right piston rod of the hydraulic cylinder 2 63 extends to push the workpiece out of the punch head 62, the left piston rod of the hydraulic cylinder 2 63 retracts and disengages from the pull plate 15. When the right piston rod of the hydraulic cylinder 2 63 retracts to the initial position, the left piston rod of the hydraulic cylinder 2 63 extends and contacts the pull plate 15, and does not push the pull plate 15 to move, which can ensure that when the punch head 62 on the movable mold 6 is not replaced, the new punch head 62 in the storage frame 141 is always blocked by the blocking wheel 146. When the punch head 62 on the movable mold 6 is damaged and needs to be replaced, the entire movable mold 6 first retreats to the left to the initial position, and then the right piston rod of the hydraulic cylinder 2 63 is controlled to continue to retract, so as to drive the right push block 64 to push the slide plate 65 to move to the left. The slide plate 65 moves to the left and pushes the front and rear connecting frames 66 closer to each other through the push rod 68 thereon, thereby pulling the block 69 out of the slot 611 on the punch head 62 to release the lock on the punch head 62. The punch head 62 falls under the action of its own gravity, and then falls into the receiving frame 12 through the through opening 13. When the right piston rod of hydraulic cylinder 2 63 continues to retract, the left piston rod of hydraulic cylinder 2 63 continues to extend to push the pull plate 15 to move to the left. The pull plate 15 moves to the left, driving the connecting plate 144 to move to the left, compressing the spring 145. The connecting plate 144 drives the blocking wheel 146 to move to the left, releasing the positioning of the new punch head 62 thereon, and the new punch head 62 then falls through the opening 13 to the front and rear connecting frames 66 of the movable mold 6. At the same time, the electric push rod 148 is controlled to drive the support block 149 to move to the right to support the new punch head 62 to prevent the new punch head 62 from sliding down directly from the connecting frame 66. Then the right piston rod of the second hydraulic cylinder 63 is controlled to extend to drive the push block 64 to move rightward and reset, and the right push block 64 then disengages from the slide plate 65 to the right, and then the left push block 64 contacts the slide plate 65 to the right and pushes the slide plate 65 to move rightward and reset, and the slide plate 65 moves rightward and pushes the front and rear connecting frames 66 away from each other through the push rod 68 on it, so that the clamping block 69 is inserted into the clamping groove 611 on the punch head 62 to lock the punch head 62. In this way, the device realizes a more efficient and convenient replacement process of the punch head 62, and can automatically complete the replacement of the punch head 62 while waiting for the cold heading workpiece, without stopping the machine to replace the punch head 62, thereby improving the overall processing efficiency.When the right piston rod of the hydraulic cylinder 2 63 is extended, the left piston rod of the hydraulic cylinder 2 63 is retracted. Under the reset action of the spring 145, the connecting plate 144 is pushed to drive the blocking wheel 146 and the pull plate 15 to move rightward and reset. Then the right piston rod of the hydraulic cylinder 2 63 is controlled to retract into the punch head 62 to avoid affecting the subsequent cold heading operation of the punch head 62, which can ensure the smooth operation of the cold heading of the workpiece by the punch head 62. When the right piston rod of the hydraulic cylinder 2 63 is retracted into the punch head 62, the left push block 64 is driven to disengage from the slide plate 65 to the left, and the right push block 64 is driven to approach the slide plate 65 to the left, which avoids hindering the subsequent right piston rod of the hydraulic cylinder 2 63 from ejecting the workpiece on the punch head 62, which can ensure the smooth operation of the hydraulic cylinder 2 63 ejecting the workpiece. Finally, the electric push rod 148 is controlled to drive the support block 149 to move leftward and disengage from the punch head 62 to avoid hindering the replacement of the punch head 62 next time.

[0038] See also Figure 10-11 A feeding mechanism is provided on the front side of the mounting seat 3, and the feeding mechanism includes a feeding channel 161 connected to the front side of the mounting seat 3. Two upper and lower electric wheels 162 for pushing the rods are installed in the middle of the feeding channel 161. Two front and rear hydraulic tools 163 for cutting the rods are installed on the left side of the feeding channel 161. The hydraulic tool 163 includes a hydraulic cylinder and a cutter. The hydraulic cylinder is installed on the feeding channel 161, and the cutter is installed on the piston rod of the hydraulic cylinder. The piston rod of the hydraulic cylinder can be controlled to extend to push the cutter to move toward the direction close to the rod to cut the rod.

[0039] Insert the bar into the feed channel 161, then control the electric wheel 2 162 to push the bar to the left, then control the front end electric clamp 10 to clamp the bar, and then control the hydraulic tool 163 to cut the bar, and then control the linear motor 8 to drive the movable frame 9 to drive the electric clamp 10 to move backward, so that the cut bar is moved backward to align with the front end fixed mold 71, and the workpiece that has been cold headed is moved backward to align with the next fixed mold 71. In this way, the device achieves efficient cutting of bars without the need for additional independent cutting machines, simplifies the layout of the production line, and improves production efficiency. Before the next bar pushing operation, control the linear motor 8 to drive the movable frame 9 to drive the electric clamp 10 to move forward and reset, so as to prevent the subsequent electric clamp 10 from being blocked by the bar and unable to move forward.

[0040] See also Figure 10-11A cleaning mechanism for cleaning the rods is provided on the feed channel 161, and the cleaning mechanism includes an annular brush 171 rotatably connected to the right end of the feed channel 161. A driving motor 172 is installed on the right side of the bottom of the feed channel 161. The driving motor 172 is connected to the annular brush 171 through a gear set 173. The gear set 173 consists of two gears, and the two gears are respectively connected to the output shaft of the driving motor 172 and the outer wall of the annular brush 171, and the two gears are meshed.

[0041] The rod is inserted into the feed channel 161 through the annular brush 171, and the driving motor 172 drives the gear set 173 to drive the annular brush 171 to rotate. The rotation of the annular brush 171 can clean the impurities on the surface of the rod, so as to remove the impurities adhering to the surface of the rod and improve the cleanliness of the surface of the rod, which is beneficial to improving the cold heading effect of the rod and the product forming quality.

[0042] See also Figure 12-13 A cleaning mechanism for cleaning the workpiece is provided between the base 2 and the mounting seat 3, and the cleaning mechanism includes a cleaning frame 181 connected between the base 2 and the mounting seat 3. A liquid spraying pipe 182 for spraying liquid toward the lower right is installed on the left inner wall of the cleaning frame 181. A filter screen 183 is connected to the inner rear side of the cleaning frame 181. The inner bottom surface of the cleaning frame 181 is a slope with a high front and a low rear so as to guide the liquid and the workpiece to the filter screen 183. A drain pipe 184 located at the lower side of the filter screen 183 is connected to the left rear side of the cleaning frame 181.

[0043] After the electric clamp 10 releases the workpiece after cold heading, the workpiece after cold heading falls into the cleaning frame 181, and the spray pipe 182 is connected to the infusion device, and the cleaning liquid is input into the spray pipe 182 through the infusion device. The spray pipe 182 sprays the cleaning liquid to the lower right on the workpiece to clean the workpiece, remove the oil stains on the workpiece, and improve the cleanliness of the workpiece. The waste liquid and the workpiece then slide backward along the inclined surface of the bottom surface of the cleaning frame 181 to the filter 183, and the workpiece is intercepted by the filter 183, and the waste liquid falls below the filter 183, and then is discharged outward through the drain pipe 184.

[0044] See also Figure 3 A conveyor belt 19 is provided in the material receiving frame 12, and the punch head 62 entering the material receiving frame 12 falls on the conveyor belt 19. The rotation of the conveyor belt 19 can send the replaced punch head 62 backward from the material receiving frame 12, thereby eliminating the need to manually remove the punch head 62 from the material receiving frame 12, which can save time and effort.
