Abstract
Description
Technical Field
[0001] This utility model relates to the field of press feeding technology, specifically a press head and tail material connection mechanism. Background Technology
[0002] When producing the same product continuously, the material needs to be fed into the mold of the press before feeding. Then, the material is manually fed from the front end of the mold to the rear end. Each step requires manual confirmation of the feeding position. When the material reaches the rear end, it needs to be manually fed back into the mold until all the material that can be fed into the mold has been fed. Finally, the remaining material in the feeder is cut off, pulled out, and discarded. Then, the material is fed again. The feeding and finishing process is not only time-consuming and labor-intensive, but also wastes materials.
[0003] Therefore, we propose a head-and-tail material connection mechanism that connects the tail end of the previous roll of material to the head end of the next roll of material to improve the material utilization rate in the press. Utility Model Content
[0004] The purpose of this invention is to provide a material connection mechanism for the beginning and end of a press, so as to solve the problem of material waste in the feeding and finishing processes of the press mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a first and last material connection mechanism for a press, comprising a worktable, wherein a last material clamping mechanism, a welding machine and a first material clamping mechanism are mounted on the top of the worktable, and the welding machine is located between the last material clamping mechanism and the first material clamping mechanism;
[0006] Both the tail material clamping mechanism and the first material clamping mechanism include a base plate, a seat plate on the upper side of the base plate, a guide column installed above the seat plate, and a top plate installed above the guide column; a pressure plate is slidably connected to the outer side of the guide column, an upper pressure plate is installed below the pressure plate, and a push rod for driving the pressure plate to slide up and down is installed on the upper side of the top plate; a side pressure plate is provided below the seat plate; an extrusion hole is opened through the upper part of the seat plate, and the upper pressure plate passes through the extrusion hole.
[0007] Preferably, the first material clamping mechanism is slidably connected to the worktable, and an electric cylinder for driving the first material clamping mechanism to slide is installed above the worktable.
[0008] Preferably, the welding machine is slidably connected to the worktable, and a reinforcing connecting rod connects the welding machine to the first material clamping mechanism.
[0009] Preferably, there are two side pressure plates, and both side pressure plates are slidably connected to the seat plate. A telescopic rod for driving the side pressure plates to slide is also installed on the lower side of the seat plate; the upper pressure plate is located between the two side pressure plates.
[0010] Preferably, the side pressure plate includes an adjusting pressure plate and a positioning pressure plate, and the positioning pressure plates of the tail material clamping mechanism and the first material clamping mechanism are located on the same side; a positioning groove is provided on the lower side of the positioning pressure plate, and a positioning plate corresponding to the positioning groove is installed on the upper side of the bottom plate.
[0011] Preferably, both the adjusting plate and the positioning plate include a counter plate and an anti-detachment plate, with the anti-detachment plate located on the upper side of the counter plate.
[0012] Preferably, the workbench is a hollow box with casters installed at its four corners.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1) This device fixes two rolls of products of the same size by means of a tail material clamping mechanism and a head material clamping mechanism. Then, the welding machine welds the head and tail ends of the two rolls of material, thereby extending the relative length of the material, so that there is no tail material, reducing the time and material wasted by manual feeding and cutting, and improving production efficiency and material utilization.
[0015] 2) This device ensures the alignment of the material width direction through the side pressure plate. When the die of the press is fed, the material is on the same plane, which can prevent the weld joint of the material from getting stuck at the pre-feeding end. Also, the fact that the material is on the same plane can prevent the weld joint of the material from damaging the die. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example
[0025] Please see Figures 1-6 This utility model provides a technical solution: a first and last material connection mechanism for a press, including a worktable 1, a last material clamping mechanism 3, a welding machine 4, and a first material clamping mechanism 5. The last material clamping mechanism 3, the welding machine 4, and the first material clamping mechanism 5 are all installed above the worktable 1, and the welding machine 4 is located between the last material clamping mechanism 3 and the first material clamping mechanism 5. During operation, the last material clamping mechanism 3 fixes the tail end of the previous roll of material, and the first material clamping mechanism 5 fixes the first segment of the next roll of material (the two rolls of material are the same size). Then, by aligning the two rolls of material and placing their joint within the welding area of the welding machine 4 (this is prior art and will not be described in detail here), the welding machine 4 welds the tail end of the previous roll of material to the first segment of the next roll of material together. After the two rolls of material are welded together, the relative length of the material can be extended, so that the material entering the press does not have a "tail end", thereby avoiding material waste. Example
[0026] Please see Figures 1-5 This utility model provides a technical solution: a material connection mechanism for the beginning and end of a press, which also includes an electric cylinder 6 and a reinforcing connecting rod 7.
[0027] The tail material clamping mechanism 3 has the same structure as the first material clamping mechanism 5, both including a base plate 51, a seat plate 52, a guide column 53, a pressure plate 54, a top plate 55, a push rod 56, an upper pressure plate 57, a telescopic rod 58, and a side pressure plate 59. The difference between the tail material clamping mechanism 3 and the first material clamping mechanism 5 is that the base plate 51 of the tail material clamping mechanism 3 is fixed to the worktable 1 by bolts, while the base plate 51 of the first material clamping mechanism 5 is slidably connected to the worktable 1 by a slider. A seat plate 52 is provided on the upper side of the base plate 51, and a partition is provided between the base plate 51 and the seat plate 52. The partition separates a material passage area between the base plate 51 and the seat plate 52, through which the material entering the press passes. Guide posts 53 are installed at the four corners of the upper part of the seat plate 52. A top plate 55 is installed on the upper side of the guide posts 53. The four guide posts 53 together support the top plate 55. The guide posts 53 adopt cylindrical guide rails, and cylindrical sliders are sleeved on their outer sides. The pressure plate 54 is connected to the cylindrical sliders by bolts, so that the pressure plate 54 can slide up and down along the guide posts 53. The push rod 56 is a pneumatic push rod, which is installed on the upper side of the top plate 55. A cylindrical hole is opened through the upper side of the top plate 55. The telescopic end of the push rod 56 passes through the cylindrical hole and is fixedly connected to the pressure plate 54. An upper pressure plate 57 is installed on the lower side of the pressure plate 54. An extrusion hole is opened through the upper part of the seat plate 52. The upper pressure plate 57 passes through the extrusion hole. When clamping materials, the push rod 56 pushes the pressure plate 54 down, and the pressure plate 54 drives the upper pressure plate 57 to move down. Finally, the upper pressure plate 57 and the bottom plate 51 work together to clamp and fix the materials. Two side pressure plates 59 are installed below the seat plate 52, located on the left and right sides of the upper pressure plate 57 respectively. A linear guide rail is provided on the lower side of the seat plate 52, and both side pressure plates 59 are slidably connected to the linear guide rail via sliders. Telescopic rods 58 are electric push rods installed on the lower side of the seat plate 52. Two telescopic rods 58 are also present, with their telescopic ends connected to the side pressure plates 59, used to drive the two side pressure plates 59 to slide. The two side pressure plates 59 clamp the material on the left and right sides, completing the material positioning. When the telescopic rods 58 push the side pressure plates 59 to clamp the material, it is necessary to prevent excessive pressure that could cause material deformation. This can be achieved by monitoring with a pressure sensor to prevent excessive pressure, or by presetting the material width and then having the electric push rods push the side pressure plates 59 to slide a fixed distance to clamp the material.
[0028] Since the end position of the previous roll of material is not clear, the first material clamping mechanism 5 needs to move the first segment of the next roll of material so that it can align with the end of the previous roll of material. A linear guide rail is installed on the worktable 1. The base plate 51 of the first material clamping mechanism 5 is connected to the linear guide rail of the worktable 1 via a slider. An electric cylinder 6 is installed above the worktable 1. The output end of the electric cylinder 6 is connected to the base plate 51 of the first material clamping mechanism 5 to push the first material clamping mechanism 5 to slide. In order to facilitate the welding position of the two rolls of material to be within the welding area of the welding machine 4, the lower end of the welding machine 4 is also connected to the linear guide rail of the worktable 1 via a slider. A reinforcing link 7 is connected between the welding machine 4 and the first material clamping mechanism 5. The first material clamping mechanism 5 drives the welding machine 4 to move synchronously via the reinforcing link 7.
[0029] The tail end of the previous roll of material and the first section of the next roll of material need to be aligned during welding. Therefore, the upper surface of the base plate 51 in the tail material clamping mechanism 3 and the upper surface of the base plate 51 in the first material clamping mechanism 5 are set on the same horizontal plane. The side pressure plate 59 includes an adjusting pressure plate and a positioning pressure plate. The positioning pressure plates of the tail material clamping mechanism 3 and the first material clamping mechanism 5 are located on the same side. When positioning the material, the side where the positioning pressure plate is located is used as the positioning reference plane, so that the two rolls of material can also be aligned on the side. A positioning groove 593 is opened on the lower side of the positioning pressure plate, and a positioning plate 594 corresponding to the positioning groove 593 is installed on the upper side of the base plate 51. The positioning plate 594 is set in a T-shape. The protrusion on the T-shape is used to position the positioning pressure plate. When the telescopic rod 58 pushes the positioning pressure plate to slide, when the protrusion on the positioning plate 594 blocks the positioning groove 593, the positioning pressure plate cannot continue to move. At this time, the positioning pressure plate reaches the reference plane.
[0030] Both the adjusting pressure plate and the positioning pressure plate include a counter pressure plate 591 and an anti-detachment plate 592. The anti-detachment plate 592 is located on the upper side of the counter pressure plate 591. The anti-detachment plate 592 extends out of the counter pressure plate 591 on the side near the upper pressure plate 57. When positioning the material, the extended end of the anti-detachment plate 592 prevents the material from warping.
[0031] The device is installed at the feed end of the press. The material passes through the tail clamping mechanism 3, the welding machine 4, and the first material clamping mechanism 5. After the tail end of the previous roll of material passes the first material clamping mechanism 5 (the material can be monitored by a sensor, and an alarm can be used to remind the worker), the next roll of material is manually fed into the first material clamping mechanism 5, and the first section of the next roll of material is extended into the welding area of the welding machine 4. Then, the telescopic rod 58 in the tail clamping mechanism 3 and the first material clamping mechanism 5 is activated. The telescopic rod 58 pushes the side pressure plates 59 to move closer together, and the left and right side pressure plates 59 clamp the material. The positioning pressure plate in the side pressure plate 59 is blocked by the positioning plate 594, stopping the sliding in advance, thus forming a positioning reference surface. Then, the push rod 56 in the tail clamping mechanism 3 and the first material clamping mechanism 5 pushes the bearing plate 54 and the upper pressure plate 57 downward. The upper pressure plate 57 and the bottom plate 51 work together to press the material.
[0032] Start the electric cylinder 6, which pushes the first material clamping mechanism 5 to slide. The first material clamping mechanism 5 drives the welding machine 4 to slide through the reinforcing connecting rod 7. Finally, the hand end of the first material clamping mechanism 5 holding the material is aligned with the tail end of the material clamping mechanism 3 (which can be monitored by a sensor). Then, the welding machine 4 welds the first and tail sections of the two rolls of material. After welding is completed, the telescopic rod 58 on the tail material clamping mechanism 3 and the first material clamping mechanism 5 drives the side pressure plate 59 to slide, and the side pressure plate 59 releases the material. Example
[0033] Please see Figures 1-4 , Figure 6 This utility model provides a technical solution: a material connection mechanism for the beginning and end of a press, which also includes casters 2.
[0034] The tail material clamping mechanism 3 has the same structure as the first material clamping mechanism 5, both including a base plate 51, a seat plate 52, a guide column 53, a pressure plate 54, a top plate 55, a push rod 56, an upper pressure plate 57, a telescopic rod 58, and a side pressure plate 59. Both the tail material clamping mechanism 3 and the first material clamping mechanism 5 are fixed to the worktable via the base plate 51. A seat plate 52 is provided on the upper side of the base plate 51, and a partition is provided between the base plate 5 and the seat plate 52. The partition is located on the left or right side above the base plate 51, so that the partition, base plate 51, and seat plate 52 form a "C"-shaped material passage area, and the material can be inserted into the material passage area through the "C"-shaped notch. A similar "C"-shaped area is also provided on the lower side of the welding machine 4 to facilitate material insertion.
[0035] Guide posts 53 are installed at the four corners of the upper part of the seat plate 52. A top plate 55 is installed on the upper side of the guide posts 53. The four guide posts 53 together support the top plate 55. The guide posts 53 adopt cylindrical guide rails, and cylindrical sliders are sleeved on their outer sides. The pressure plate 54 is connected to the cylindrical sliders by bolts, so that the pressure plate 54 can slide up and down along the guide posts 53. The push rod 56 is an electric push rod, which is installed on the upper side of the top plate 55. A cylindrical hole is opened through the upper side of the top plate 55. The telescopic end of the push rod 56 passes through the cylindrical hole and is fixedly connected to the pressure plate 54. An upper pressure plate 57 is installed on the lower side of the pressure plate 54. An extrusion hole is opened through the upper part of the seat plate 52. The upper pressure plate 57 passes through the extrusion hole. When clamping materials, the push rod 56 pushes the pressure plate 54 down, and the pressure plate 54 drives the upper pressure plate 57 to move down. Finally, the upper pressure plate 57 and the bottom plate 51 work together to clamp and fix the materials.
[0036] A side pressure plate 59 is provided below the seat plate 52. The side pressure plate 59 and the partition are located on the same side and are fixedly connected to the seat plate 52. The positioning surface of the side pressure plate 59 in the tail material clamping mechanism 3 and the positioning surface of the side pressure plate 59 in the first material clamping mechanism 5 are located in the same plane. The tail end of the previous roll of material is manually inserted into the tail material clamping mechanism 3, and the first section of the next roll of material is inserted into the clamping mechanism 5. The two rolls of material are then positioned and aligned by the side pressure plate 59.
[0037] Both the adjusting pressure plate and the positioning pressure plate include a counter pressure plate 591 and an anti-detachment plate 592. The anti-detachment plate 592 is located on the upper side of the counter pressure plate 591. The anti-detachment plate 592 extends out of the counter pressure plate 591 on the side near the upper pressure plate 57. When positioning the material, the extended end of the anti-detachment plate 592 prevents the material from warping.
[0038] The workbench 1 is a hollow box housing a portable power supply. The power required for the push rod 56 and the welding machine 4 is supplied by the portable power supply. Casters 2, equipped with brakes, are installed at each of the four corners of the workbench 1. During use, the operator can push the workbench 1 to perform final welding on materials from different presses using this device.
[0039] The operator pushes the device to the feed end of the press, then manually inserts the first section of the next roll of material into the first material clamping mechanism 5, and extends it into the welding area of the welding machine 4; then inserts the last end of the previous roll of material into the last material clamping mechanism 3, and extends it into the welding area of the welding machine 4; during this process, one end of both rolls of material is aligned with the side pressure plate 59, then the push rod 56 in the last material clamping mechanism 3 and the first material clamping mechanism 5 is activated, the push rod 56 pushes the pressure plate 54 and the upper pressure plate 57 downward, the upper pressure plate 57 and the bottom plate 51 work together to press the material, then the operator manually locks the casters 2; then the welding machine 4 welds the first and last sections of the two rolls of material; after welding is completed, the operator manually releases the casters 2 and pushes the worktable 1 to move to the next press that needs to weld the first and last ends of the material.
