Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and particularly to a cutting device for anchor bolt production. Background Art

[0002] An anchor bolt is a fastener used to fix an object to concrete, masonry, or other brittle substrates. During the production process of anchor bolts, it is necessary to cut the anchor bolts according to customer requirements to obtain products of a specified length.

[0003] After retrieval, a Chinese patent with the patent publication number CN117359009B, an automatic cutting device for anchor bolt production, includes a cutting table and a cutting mechanism, and also includes a rotating roller, a driving motor, a support table, an auxiliary limiting component, a fixing component, a fixing plate, a blocking component, a height adjusting component, a storage box, a first limiting component, and a second limiting component. A through hole is formed in the cutting table, the rotating roller is rotatably arranged in the through hole of the cutting table, and a first limiting groove is formed in the rotating roller. The driving motor is arranged on the side wall of the cutting table, and the output shaft of the driving motor is fixedly connected to the rotating roller. The support table is arranged on the cutting table, and a second limiting groove is formed in the support table.

[0004] Although the above patent can cut the anchor bolts to obtain anchor bolts of a specified length, it lacks a mechanism for grinding and deburring the cutting surface of the anchor bolts. Usually, burrs and unevenness will be left at the cut after the anchor bolts are cut. These burrs make the cutting surface of the anchor bolts sharp and rough, which not only affects the appearance quality but may also cause scratches to the operators during handling or storage. To improve the quality of the anchor bolts, additional grinding equipment needs to be equipped to grind and deburr the cutting surface of the anchor bolts. However, additional grinding equipment will not only increase the cost but also require manual transfer of the anchor bolts between the cutting device and the grinding equipment, which is not only time-consuming and laborious but also reduces the overall production efficiency.

Detailed implementation manner

[0032] Refer to Figures 1 - 4, A cutting device for anchor bolt production, comprising a workbench 1. On the left side of the top of the workbench 1, there is a gantry 2 connected. The gantry 2 includes two sets of front and rear vertical rods connected to the left side of the top of the workbench 1 and a mounting plate connecting the tops of the two sets of vertical rods. The number of vertical rods in each set is two, and the two vertical rods in each set are arranged left and right. Between the two sets of front and rear vertical rods on the gantry 2, there is a first lifting plate 3 slidably connected. The first lifting plate 3 includes a cross plate slidably connected to the vertical rods and an inverted U-shaped plate connected to the top of the cross plate. A circular saw 4 is installed on the cross plate of the first lifting plate 3, and the circular saw 4 is located inside the inverted U-shaped plate of the first lifting plate 3. In the middle of the mounting plate of the gantry 2, there is a hydraulic cylinder 5 installed. The telescopic rod of the hydraulic cylinder 5 is connected to the top of the inverted U-shaped plate of the first lifting plate 3 to drive the first lifting plate 3 to drive the circular saw 4 to lift and cut the anchor bolt. On the upper left part of the workbench 1, there are two sets of sliding rods 6 slidably connected in the front and rear directions. The number of sliding rods 6 in each set is two, and the two sliding rods 6 in each set are arranged front and rear. The sliding rods 6 are located outside the circular saw 4. Between the left ends of the two sets of sliding rods 6, there is a movable plate 7 connected. On the top of the workbench 1 and the movable plate 7, there are electric wheels 8 for conveying the anchor bolts. There is one electric wheel 8 on the movable plate 7, and there are two electric wheels 8 on the top of the workbench 1, located on the right side of the gantry 2. The electric wheel 8 includes a runner, a motor, and a rubber strip. The output shaft of the motor is connected to the runner. The runner is designed with a lower middle part and higher front and rear sides, which is beneficial for the centering placement of the anchor bolt and can ensure the stability of the anchor bolt during processing, avoiding deviation, and at the same time improving the accuracy of cutting and grinding operations. Along the circumference of the runner, there are rubber strips connected at intervals to increase the friction with the anchor bolt to ensure the smooth conveyance of the anchor bolt. The runner of the electric wheel 8 on the movable plate 7 is rotatably connected to the movable plate 7, and the motor of the electric wheel 8 on the movable plate 7 is installed on the movable plate 7. The runner of the electric wheel 8 on the workbench 1 is rotatably connected to the top of the workbench 1, and the motor of the electric wheel 8 on the workbench 1 is installed on the top of the workbench 1. On the top of the workbench 1 and the top of the movable plate 7, there are clamps 9 for clamping and fixing the anchor bolt on the electric wheel 8. There is one clamp 9 on the movable plate 7, and there are two clamps 9 on the top of the workbench 1. On the left side of the top of the workbench 1, there is an opening 41 for the circular saw 4 to lift and cut the anchor bolt. On the gantry 2, there is a grinding mechanism for grinding the cutting surface of the anchor bolt.

[0033] See Figures 2 - 3, the fixture 9 includes a guide rod 91, a second lifting plate 92, a first spring 93, and an inverted V-shaped clamping block 94. There are two front and rear guide rods 91. The second lifting plate 92 is slidably connected to the two front and rear guide rods 91. The guide rod 91 of the fixture 9 on the movable plate 7 is installed on the top of the movable plate 7, and the guide rod 91 of the fixture 9 on the workbench 1 is installed on the top of the workbench 1. The second lifting plate 92 is located directly above the electric wheel 8 on the same side. A first spring 93 is sleeved on the guide rod 91. The two ends of the first spring 93 of the fixture 9 on the movable plate 7 are respectively connected to the movable plate 7 and the second lifting plate 92. The two ends of the first spring 93 of the fixture 9 on the workbench 1 are respectively connected to the workbench 1 and the second lifting plate 92. Two left and right inverted V-shaped clamping blocks 94 are connected to the bottom of the second lifting plate 92. Through slots for the inverted V-shaped clamping blocks 94 to move up and down are opened on both the top of the workbench 1 and the movable plate 7. Rotating rollers 95 are symmetrically arranged in the front and rear on the inverted V-shaped clamping blocks 94. The friction between the inverted V-shaped clamping blocks 94 and the anchor bolts can be reduced through the rotating rollers 95, ensuring that the anchor bolts can be smoothly conveyed to the left by the electric wheel 8.

[0034] Participate Figures 4 - 6, the grinding mechanism includes a lifting frame 101 slidably connected to the gantry 2. The lifting frame 101 includes an L-shaped plate 1001, a sliding sleeve 1002, a T-shaped plate 1003, and an annular guide rail 1004. The front and rear sliding sleeves 1002 are respectively slidably connected to the front and rear groups of vertical rods on the gantry 2. On the side where the front and rear sliding sleeves 1002 are close to each other, there is an L-shaped plate 1001 located in the through-opening 41. The tops of the two L-shaped plates 1001 slidably penetrate through the cross plate on the first lifting plate 3 and are in contact with the cross plate on the first lifting plate 3. At the lower part of the side where the two L-shaped plates 1001 are close to each other, there is a T-shaped plate 1003 connected. An annular guide rail 1004 is connected between the two T-shaped plates 1003. A second spring 102 is sleeved on the lower part of the vertical rod of the gantry 2. The two ends of the second spring 102 are respectively connected to the bottom of the sliding sleeve 1002 and the top of the workbench 1. A wire grinding disc 103 located in the through-opening 41 is rotatably arranged in the annular guide rail 1004. A driving component for driving the wire grinding disc 103 to rotate is arranged at the lower part of the front T-shaped plate 1003. The driving component includes a driving motor 107 installed at the lower part of the front T-shaped plate 1003. A gear 108 is connected to the output shaft of the driving motor 107. A receiving groove for receiving the gear 108 is opened at the lower part of the front T-shaped plate 1003 to shield and protect the gear 108 to prevent waste chips from falling on the gear 108 and causing the gear 108 to jam. A gear ring 109 located in the annular guide rail 1004 is connected to the wire grinding disc 103. The gear ring 109 meshes with the gear 108. A thrust component is arranged between the L-shaped plate 1001 of the lifting frame 101 and the movable plate 7. When the lifting frame 101 moves upward, it drives the thrust component to push the movable plate 7 to move leftward. When the lifting frame 101 moves downward, it drives the thrust component to push the movable plate 7 to move rightward. The thrust component includes two connecting plates 104 symmetrically connected to the bottom of the movable plate 7 front and rear. A guide groove 105 is opened on the connecting plate 104. The guide groove 105 includes an inclined section and a vertical section. The vertical section is located above the inclined section. L-shaped push rods 106 are respectively connected to the lower part of the side where the two L-shaped plates 1001 are close to each other. The L-shaped push rods 106 are located below the T-shaped plate 1003. The two L-shaped push rods 106 are respectively located in the two guide grooves 105.

[0035] Place the anchor bolt on the electric wheel 8 on the workbench 1 to the left. Then, control the rotation of the electric wheel 8 to convey the anchor bolt to the left. When the anchor bolt moves to the left and contacts the inclined surface inside the inverted V-shaped clamping block 94, the anchor bolt continues to move to the left and presses against the inclined surface inside the inverted V-shaped clamping block 94, so as to push the inverted V-shaped clamping block 94 upward, thereby driving the second lifting plate 92 to move upward and stretching the first spring 93. Through the first spring 93, the roller 95 on the inverted V-shaped clamping block 94 is pressed tightly against the anchor bolt to achieve the positioning of the anchor bolt and prevent the anchor bolt from shifting when being conveyed to the left. When the anchor bolt moves to the electric wheel 8 on the movable plate 7 and moves to the required length to the left, control the hydraulic cylinder 5 to drive the first lifting plate 3 to drive the circular saw 4 to move downward. At the same time, control the circular saw 4 to rotate. The rotation and downward movement of the circular saw 4 can cut the anchor bolt. The anchor bolt can be clamped and fixed on the electric wheel 8 through the fixture 9 to prevent the anchor bolt from displacing by itself.

[0036] After one cutting is completed, control the hydraulic cylinder 5 to drive the first lifting plate 3 to drive the circular saw 4 to move upward. When the first lifting plate 3 moves upward and contacts the inner top surface of the L-shaped plate 1001 on the lifting frame 101, the first lifting plate 3 continues to move upward and pushes the L-shaped plate 1001 upward, so that the entire lifting frame 101 moves upward and stretches the second spring 102. The upward movement of the lifting frame 101 drives the L-shaped push rod 106 to move upward. When the L-shaped push rod 106 moves upward in the inclined section of the guide groove 105, it pushes the connecting plate 104 to drive the movable plate 7 to move to the left. The leftward movement of the movable plate 7 drives the cut anchor bolt to move to the left through the fixture 9 on it, thereby leaving a space for the wire grinding disc 103 to move upward and insert between adjacent two anchor bolts. The L-shaped push rod 106 continues to move upward and enters the vertical section of the guide groove 105, stopping to continue pushing the connecting plate 104 to the left, so as to ensure that the wire grinding disc 103 is in close contact with the cutting surface of the anchor bolt after moving upward subsequently. The upward movement of the lifting frame 101 drives the wire grinding disc 103 to move upward and insert between adjacent two anchor bolts. The wire grinding disc 103 is in close contact with the cutting surface of the anchor bolt. Control the driving motor 107 to work to drive the gear 108 to drive the gear ring 109 to rotate, thereby driving the wire grinding disc 103 to rotate to grind and deburr the cutting surface of the anchor bolt. In this way, the appearance quality of the anchor bolt can be improved, the operator can be prevented from being scratched during handling or storage, and the safety can be improved. Therefore, this device integrates the functions of cutting and grinding the cutting surface, does not need to be equipped with additional grinding equipment, can reduce costs, does not need manual transfer of the anchor bolt between the cutting device and the grinding equipment, can save time and effort, and can improve the overall production efficiency of the anchor bolt.

[0037] After completing a grinding operation, first control the hydraulic cylinder 5 to drive the first lifting plate 3 to move downward by an appropriate distance, so as to loosen the L-shaped plate 1001 on the lifting frame 101. Under the action of gravity and the reset of the second spring 102, the lifting frame 101 drives the L-shaped push rod 106 and the wire grinding disc 103 to move downward and reset to avoid the anchor bolt, preparing for the next round of anchor bolt cutting operation. When the L-shaped push rod 106 moves downward into the inclined section of the guide groove 105, the L-shaped push rod 106 continues to move downward to push the connecting plate 104 to drive the movable plate 7 to move rightward and reset, thereby driving the cut anchor bolt to move rightward and reset. Then control the electric wheel 8 to work to push the cut anchor bolt off the movable plate 7 and convey the anchor bolt to be cut leftward to the required length.

[0038] See Figures 7 - 9 , a waste chip collection mechanism is provided on the inner top surface of the workbench 1. The waste chip collection mechanism includes a collection frame 111 connected to the inner top surface of the workbench 1. The collection frame 111 is located directly below the through opening 41. A dust collector 112 is installed on the inner top surface of the workbench 1 on the right side of the collection frame 111. The dust collector 112 is communicated with the collection frame 111 through a dust suction pipe 113. Two vertical grooves for the lifting of the L-shaped push rod 106 are symmetrically formed in the front and rear on the left side wall of the collection frame 111.

[0039] The waste chips generated during cutting and grinding fall into the collection frame 111 through the through opening 41. The dust collector 112 can extract the waste chips in the collection frame 111 through the dust suction pipe 113. The dust collector 112 is a prior art and will not be elaborated here. Thus, the recycling of waste chips can be realized, reducing the waste of materials.

[0040] See Figure 7 and Figure 9 , a sealing mechanism for sealing the cutting area is provided between the workbench 1 and the first lifting plate 3. The sealing mechanism includes a telescopic cover 121, an elastic cloth cover 122, an elastic sealing cloth cover 123 and a positioning rod 124. A telescopic cover 121 is connected between the top of the workbench 1 and the bottom of the cross plate of the first lifting plate 3. The telescopic cover 121 is located directly above the through opening 41. Elastic cloth covers 122 are connected to both the left and right sides of the telescopic cover 121. Two elastic sealing cloth covers 123 are symmetrically connected to the front and rear on the outer left wall of the collection frame 111. The two elastic sealing cloth covers 123 respectively seal the two vertical grooves on the collection frame 111. The two L-shaped push rods 106 respectively penetrate through the two elastic sealing cloth covers 123. Two groups of left and right positioning rods 124 are connected between the bottom of the mounting plate of the gantry 2 and the top of the workbench 1. The positioning rods 124 are located inside the telescopic cover 121 and are used to position the telescopic cover 121 to prevent the telescopic cover 121 from closing towards the direction close to the circular saw 4 and affecting the cutting and grinding operations. The number of each group of positioning rods 124 is two, and the two positioning rods 124 in each group are symmetrically arranged in the front and rear.

[0041] The anchor bolt moves to the left, and its left end extends out of the elastic cloth cover 122. The elastic cloth cover 122 can closely adhere to the anchor bolt. Through the cooperation of the telescopic cover 121 and the elastic cloth cover 122, the cutting and grinding area can be effectively sealed, preventing waste chips from scattering everywhere, reducing the impact of waste chips on the working environment, improving the cleanliness of the working area, protecting the physical health of operators, and enhancing the efficiency and effect of waste chip collection.

[0042] During transportation and storage, due to improper stacking, external pressure or other factors, the anchor bolt may be bent or distorted. This kind of deformation will directly affect the subsequent cutting and grinding processes of the anchor bolt, resulting in the finished product not meeting the quality standards. To correct these deformations, refer to Figures 10 - 11 , a straightening mechanism for straightening the anchor bolt is provided at the top of the workbench 1. The straightening mechanism is located between two clamps 9 on the workbench 1. The straightening mechanism includes three U-shaped frames 131 connected to the top of the workbench 1 at intervals from left to right. The three U-shaped frames 131 are located between two clamps 9 on the workbench 1. Sliding grooves are opened on the front and rear sides of the middle U-shaped frame 131 and on the top and bottom of the left and right U-shaped frames 131. A lifting plate three 132 is slidably connected between the front and rear sliding grooves of the middle U-shaped frame 131. The shape of the lifting plate three 132 is an inverted U shape. An electric push rod 134 is installed on the top of the middle U-shaped frame 131. The telescopic rod of the electric push rod 134 is connected to the top of the inverted U-shaped lifting plate three 132 to drive the lifting plate three 132 to lift and lower. A first pressing roller 133 is rotatably provided in the lower part of the middle U-shaped frame 131 and in the inverted U-shaped lifting plate three 132. Two front and rear sliding plates 135 are slidably connected between the upper and lower sliding grooves of the left and right U-shaped frames 131. A second pressing roller 136 is rotatably provided on one side of the front and rear sliding plates 135 close to each other. A pushing component is provided between the lifting plate three 132 and the sliding plate 135. When the lifting plate three 132 moves downward, it drives the pushing component to push the front and rear sliding plates 135 in the U-shaped frame 131 closer to each other. When the lifting plate three 132 moves upward, it drives the pushing component to push the front and rear sliding plates 135 in the U-shaped frame 131 away from each other. The pushing component includes a slotted inclined plate 137, a connecting rod 138 and a pushing rod 139. Slotted inclined plates 137 are connected to one side of the front and rear sliding plates 135 away from each other. Connecting rods 138 are connected to the front and rear sides of the lifting plate. A pushing rod 139 is connected to the lower part of the connecting rod 138. The pushing rod 139 is located in the slot of the slotted inclined plate 137 on the same side as it.

[0043] After passing the anchor bolt leftward through the upper and lower first pressing rollers 133 and between the front and rear first pressing rollers 133, control the electric push rod 134 to drive the third lifting plate 132 to drive the upper first pressing roller 133 to move downward to contact the anchor bolt. The downward movement of the third lifting plate 132 drives the push rod 139 to move downward through the connecting rod 138. The downward movement of the front and rear push rods 139 pushes the front and rear slotted inclined plates 137 to approach each other, so that the front and rear sliding plates 135 approach each other, and further the front and rear second pressing rollers 136 approach each other to contact the anchor bolt. Subsequently, the anchor bolt continues to move leftward. Through the cooperation of the upper and lower first pressing rollers 133 and the front and rear first pressing rollers 133, the anchor bolt can be straightened, which helps to restore the straightness of the anchor bolt and improve the quality of the finished product. When it is necessary to replace the next anchor bolt for cutting, control the electric push rod 134 to drive the third lifting plate 132 to drive the upper first pressing roller 133 to move upward to reset. The upward movement of the third lifting plate 132 drives the push rod 139 to move upward through the connecting rod 138.
