[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 , Figure 2 As shown, a punching machine with a positioning device comprises a punching machine body 1, a positioning box 2 is fixedly installed in front of the punching machine body 1, a plurality of feed rollers 3 are rotatably connected to the bottom of the inner cavity in the middle of the positioning box 2, an auxiliary feed assembly 4 is fixedly connected to the top of the inner cavity in the middle of the positioning box 2 and the auxiliary feed assembly 4 is located above the feed roller 3, the inner walls of the front and rear parts of the positioning box 2 are fixedly connected to positioning assemblies 5 and the two positioning assemblies 5 are located at the front and rear sides of the feed roller 3 and the auxiliary feed assembly 4, the left part of the upper surface of the two positioning assemblies 5 is fixedly installed with a driving adjustment assembly 6, and the outer wall of the middle part of the driving adjustment assembly 6 is fixedly connected to the inner cavity of the punching machine body 1;

[0026] First, the two positioning components 5 are adjusted according to the width of the steel bar. After the adjustment, the steel bar is passed through the middle of the two positioning components 5. At the same time, the upper and lower sides of the outer wall of the steel bar are overlapped with the opposite surfaces of the feed roller 3 and the auxiliary feed component 4 respectively. Then, under the action of the feed roller 3, the steel bar is moved toward the inside of the punch body 1. The auxiliary feed component 4 enables the steel bar to move stably under the action of the feed roller 3. Finally, the steel bar is processed by the punch body 1.

[0027] like Figure 3 As shown, the positioning assembly 5 includes a fixed frame 51, the outer wall of the fixed frame 51 is fixedly connected to the inner wall of the positioning box 2, the left and right parts of the inner wall of the fixed frame 51 are slidably connected to the limit frame 52, the upper surfaces of the two limit frames 52 are fixedly connected with sliders 53, the inner cavities of the two sliders 53 are threadedly sleeved with threaded rods 54, the left side of the threaded rod 54 is fixedly connected with a bevel gear 55, the outer walls of the left and right parts of the threaded rod 54 are respectively movably sleeved with the inner cavity of the upper part of the fixed frame 51, and the limit rod in the middle of the limit frame 52 can rotate and move;

[0028] Through the action of the two limit frames 52, the steel bar can be limited when it moves under the action of the feed roller 3, thereby ensuring the correct processing of the steel bar by the punch body 1. At the same time, since the limit rod in the middle of the limit frame 52 can be rotated and moved, it will not affect the normal movement of the steel bar, thereby facilitating the positioning of the steel bar during use.

[0029] like Figure 4 As shown, the drive adjustment component 6 includes a motor 61, the front of the motor 61 is fixedly connected to the inner cavity of the upper left part of the positioning box 2, the output end of the motor 61 is fixedly connected to a spur gear 62, the right side of the outer wall of the spur gear 62 is meshed with a combined gear set 63, the outer wall of the connecting shaft in the middle of the combined gear set 63 is movably sleeved with the inner cavity of the positioning box 2, and the right sides of the outer walls of the bevel gears in the front and rear parts of the combined gear set 63 are respectively meshed with the opposite surfaces of the outer walls of the two bevel gears 55;

[0030] Through the action of the motor 61, the spur gear 62 is rotated, thereby rotating the combined gear set 63. Under the action of the combined gear set 63, the two bevel gears 55 simultaneously drive the two threaded rods 54 to rotate, so that the four limit frames 52 are adjusted at the same time. Under the restriction of the limit frames 52, the steel bar can always be located in the middle of the inner cavity of the punch body 1, thereby facilitating positioning processing.

[0031] The inner cavity of the punch body 1 is fixedly connected with a hydraulic rod 2 65, and the output end of the hydraulic rod 2 65 is fixedly connected with a tooth plate 64. The outer wall of the tooth plate 64 is slidably connected with the inner cavity of the punch body 1, and the left side of the tooth plate 64 is meshed with the right side of the outer wall of the spur gear in the middle of the combined gear set 63;

[0032] After the distance between the two limit frames 52 is adjusted, the gear plate 64 is moved closer to the combined gear set 63 through the action of the hydraulic rod 65, so as to mesh with the spur gear in the middle thereof, thereby limiting and fixing the combined gear set 63. By fixing the combined gear set 63, the position of the limit frame 52 is limited and fixed, so that it is convenient to adjust the limit according to the size of the steel bar while ensuring its stability.

[0033] like Figure 5 As shown, the auxiliary feeding assembly 4 includes a hydraulic rod 41, the upper surface of the hydraulic rod 41 is fixedly connected to the top of the inner cavity of the positioning box 2, the output end of the hydraulic rod 41 is fixedly connected to a fixing frame 42, the outer wall of the fixing frame 42 is slidably connected to the inner cavity of the punch body 1, and the inner wall of the fixing frame 42 is rotatably connected to a plurality of auxiliary feeding rollers 43;

[0034] Through the action of the hydraulic rod 41, the fixed frame 42 pushes the auxiliary feed rollers 43 to move downward, so that the auxiliary feed rollers 3 drive the steel bars to move, so as to facilitate the adjustment of the auxiliary movement according to the size of the steel bars.

[0035] like Figure 6 As shown, the auxiliary feed roller 43 includes a central rod 431, the left and right sides of the central rod 431 are rotatably connected to the inner wall of the fixed frame 42, the outer wall of the central rod 431 is fixedly connected to a rubber interlayer 432, the outer wall of the rubber interlayer 432 is fixedly connected to a support jacket 433, and the outer wall of the support jacket 433 is fixedly connected to a rubber outer layer 434;

[0036] Since the rubber interlayer 432 is fixedly connected between the center rod 431 and the supporting jacket 433, when restricting the steel bar, the pressure can be increased while ensuring the supporting strength, thereby ensuring the smooth movement of the steel bar. Then, under the action of the rubber outer layer 434, the steel bar can fit with the outer wall of the feed roller 3 and move.

[0037] The working principle of the utility model is as follows: first, the spur gear 62 is rotated by the action of the motor 61, so that the combined gear set 63 is rotated, and under the action of the combined gear set 63, the bevel gear 55 and the threaded rod 54 are rotated, so that the two sliders 53 drive the two limit frames 52 to move toward each other, so that the distance between the two limit frames 52 can be adjusted according to the width of the steel bar. After adjustment, the steel bar is passed through the four limit frames 52, and at the same time, the upper and lower sides of the outer wall of the steel bar are overlapped with the opposite surfaces of the feed roller 3 and the auxiliary feed roller 43 respectively. Since the rubber interlayer 432 is fixedly connected between the center rod 431 and the support jacket 433, when the steel bar is restricted, the pressure can be increased while the support strength is guaranteed, thereby ensuring the smoothness of the movement of the steel bar, and then under the action of the rubber outer layer 434, the steel bar can fit with the outer wall of the feed roller 3, and then under the action of the feed roller 3, the steel bar moves to the inside of the punch body 1, and finally the steel bar is processed by the punch body 1.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
