Description

Technical Field

[0001] This utility model belongs to the field of steel processing technology, and specifically relates to a punching and cutting device for steel forging. Background Technology

[0002] Steel forging is a machining method that uses mechanical pressure to cause plastic deformation of metal billets to obtain specific shapes and mechanical properties. When steel plates are used as metal billets for forging, they need to be punched, so punching equipment is required.

[0003] In existing punching devices, the platform used to support the steel plate is usually provided with grooves to cooperate with the punching blade for punching. During the punching process, debris is generated. If the debris enters the groove and is not cleaned in time, it will cause the groove to become blocked, and the punching blade will not be able to enter the groove normally, thus affecting the punching depth and accuracy. Therefore, it requires the operator to clean frequently, which increases the labor intensity of the operator and reduces the work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a punching device for steel forging, in which the slag produced during punching falls into the collection drawer for collection, eliminating the need for frequent cleaning by workers, reducing the labor intensity of workers and improving work efficiency.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, this utility model discloses a punching and cutting device for steel forging, comprising:

[0030] The work plate 1 has a rectangular through groove 11 on its top, and sliding grooves 12 are provided on the inner walls of the front and rear sides of the rectangular through groove 11. A support assembly 13 is fixedly installed at the bottom of the work plate 1. The support assembly 13 consists of four support legs that can provide stable support for the work plate 1.

[0031] There are two support platforms 2, which are fixedly installed on the top left and right sides of the work plate 1, and one of the support platforms 2 is provided with an abutment plate 21 on the top.

[0032] The displacement stage 3 has sliders 31 fixedly installed on both the front and rear sides. The two sliders 31 are slidably assembled inside the two slide grooves 12 respectively. The top of the displacement stage 3 has a clearance through groove 311.

[0033] The drive assembly 4 is located inside one of the slide grooves 12 and is used to drive the slider 31 to move left and right. Specifically, the drive assembly 4 includes a lead screw 41, one end of which is rotatably connected to the left inner wall of the rear slide groove 12, the rear slider 31 is threadedly connected to the lead screw 41, and the other end of the lead screw 41 extends out of the working plate 1 and is fixedly connected to a turntable 42.

[0034] When it is necessary to punch the steel plate, place the steel plate between the abutment plate 21 and the displacement table 3. Adjust the movement of the displacement table 3 according to the size of the steel plate to be punched. During adjustment, simply rotate the turntable 42. The turntable 42 drives the lead screw 41 to rotate. The lead screw 41 is connected to the slider 31 by a thread, which drives the slider 31 to move. Then adjust the displacement table 3 to move left and right until it reaches the designated position. Then the punching mechanism 5 can be started to punch the steel plate. The operation is simple and convenient.

[0035] The punching mechanism 5 is fixedly installed on the top of the displacement table 3. Specifically, the punching mechanism 5 includes a U-shaped mounting plate 51, which is fixedly installed on the top of the displacement table 3. A cylinder 52 is fixedly installed on the top of the U-shaped mounting plate 51. The telescopic end of the cylinder 52 passes through the U-shaped mounting plate 51 and is fixedly installed on an assembly plate 53. A punching cutter 54 that matches the position of the clearance slot 311 is fixedly installed at the bottom of the assembly plate 53.

[0036] After the steel plate is placed, when punching is required, the operator starts the cylinder 52, which drives the punching blade 54 to move down. Together with the clearance channel 311, the steel plate is cut. After the cutting is completed, the debris produced by the cutting falls into the collection mechanism 6 through the clearance channel 311 and is collected directly. This can effectively prevent the debris from accumulating and affecting the punching blade 54's cutting of the steel. At the same time, the collection mechanism 6 moves with the displacement table 4, playing a role in real-time collection of debris.

[0037] The collection mechanism 6 is installed at the bottom of the displacement stage 3. Specifically, the collection mechanism 6 includes a collection box 61, which is fixedly installed at the bottom of the displacement stage 3. An opening is provided at the lower front side of the collection box 61, and a collection drawer 62 is slidably fitted inside the opening. A locking component is provided between the collection drawer 62 and the collection box 61.

[0038] In the initial state, the locking assembly collects the debris in the collection drawer 62. After the debris falls through the clearance groove 311, it will fall directly into the collection drawer 62. After a period of cutting, the locking assembly is released, and the collection drawer 62 is pulled out to process the debris. The operation is simple and convenient. The collection drawer 62 moves in real time with the displacement table 3, which can collect the debris more effectively and reduce the labor intensity of the workers.

[0039] The displacement stage 3 is provided with a bearing mechanism 7 on both the left and right sides. The bearing mechanism 7 includes two first springs 71. One end of each of the two first springs 71 is fixedly connected to the displacement stage 3. A first bearing block 72 is fixedly installed on the side of each of the two first springs 71 away from the displacement stage 3. Two second springs 731 are fixedly installed on the side of each first bearing block 72 away from the displacement stage 3. A second bearing block 73 is fixedly installed on the side of each of the two second springs 731 away from the first bearing block 72. A limit block 74 is fixedly installed on the front side of each of the first bearing block 72 and the second bearing block 73. The limit block 74 is slidably connected to the front slide groove 12.

[0040] In the initial state, under the action of the two first springs 71 and the two second springs 731, the two first bearing blocks 72 and the two second bearing blocks 73 are evenly distributed inside the rectangular through groove 11. The tops of the two first bearing blocks 72, the two second bearing blocks 73, the displacement table 3, and the two support tables 2 are all flush, which facilitates the placement of steel plates by the workers. The two first bearing blocks 72 and the two second bearing blocks 73 provide additional support points for the steel plates, increasing the punching stability. As the middle displacement table 3 moves left and right, it will push the two first bearing blocks 72 and the two second bearing blocks 73 to move synchronously through the two first springs 71 and the two second springs 731. When the two second bearing blocks 71 abut against the inner wall of the rectangular through groove 11, the continued movement will compress the two second springs 731. This ensures that the bottom of the steel plate to be punched can always have a certain support, increasing the cutting stability. At the same time, the displacement table 3 also has a certain displacement stroke, making it highly adaptable.

[0041] A U-shaped mounting plate 75 is fixedly installed on the top of the first bearing block 72. An electric push rod 76 is fixedly installed on the top of the U-shaped mounting plate 75. The telescopic end of the electric push rod 76 passes through the U-shaped mounting plate 75 and is fixedly installed with a pressing plate 77.

[0042] When punching the steel plate, the operator first activates the two electric push rods 76. The downward movement of the telescopic ends of the two electric push rods 76 can drive the pressing plate 77 to contact the surface of the steel plate and press and fix the steel plate, which can effectively improve the stability and punching effect during subsequent punching.

[0043] The front and rear sides of the top of the working plate 1 are fixedly installed with horizontal blocks 78, and the top of the horizontal blocks 78 is provided with scale lines 79. When adjusting the required cutting size, after the steel plate abuts against the abutment plate 21 on one side, the required punching size can be determined by comparing the position of the scale line 79 with that of the punching blade 54, resulting in higher cutting accuracy.

[0044] The device is used as follows:

[0045] When needed, the steel plate is placed on two support platforms 2. The two bearing mechanisms 7 and the displacement platform 3 provide auxiliary support. One side of the steel plate abuts against the abutment plate 21. The displacement platform 3 is then adjusted left and right according to the scale line 79. During displacement, the turntable 42 is rotated, which drives the lead screw 41 to rotate. The lead screw 41 drives the slider 31 to move, and the slider 3 drives the displacement platform 3 to move to a certain position. After the displacement is completed, the cylinder 52 is activated. The cylinder 52 drives the punching blade 54 downward to punch the steel plate. The debris generated by punching will fall downward through the clearance groove 311 and enter the collection drawer 62 for collection. This can effectively collect the debris and avoid the debris accumulation affecting the punching blade 64. It also eliminates the need for frequent handling by the staff and reduces the labor intensity of the staff.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
