DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-5 As shown, a manufacturing device of a low-resistance alloy resistor of the utility model comprises a base 1, a support frame 10 is fixedly provided on the upper side of the base 1, a hydraulic cylinder 11 is installed on the upper side of the support frame 10, a cutting knife 12 is installed on the output end of the hydraulic cylinder 11, a placement seat 13 is slidably mounted on the upper side of the base 1, a plurality of placement grooves 14 distributed linearly are provided on the upper side of the placement seat 13, a slide groove 15 is provided on the upper side of the base 1, a screw 16 is rotatably mounted in the slide groove 15, a motor 17 is installed on the rear side of the base 1, the output shaft of the motor 17 is transmission-connected with the screw 16, a block 18 threadedly connected with the screw 16 is fixedly provided on the lower side of the placement seat 13, two side plates 19 symmetrically distributed on the left and right are fixedly provided on the upper side of the base 1, the two side plates 17 are jointly provided with a clamping assembly matching the placement seat 13, and the placement seat 13 is provided with a plurality of telescopic parts matching the placement grooves 14;

[0022] When the utility model is used, the operator first places the alloy resistor in the placement groove 18 on the upper side of the placement seat 13, and the rear side of the alloy resistor abuts against the side wall of the placement groove 18 to align the alloy resistor. The operator starts the motor 17, and the output shaft of the motor 17 drives the screw 16 to rotate. The screw 16 drives the placement seat 13 to move on the base 1 through the block 18. After the block 18 abuts against the rear side of the slide groove 15, the motor 17 stops running, the placement seat 13 is located at the rear side of the base 1, and the rear side of the placement seat 13 and the cutting knife 12 are in the same vertical plane. The operator starts the hydraulic cylinder 11, and the output end of the hydraulic cylinder 11 drives the cutting knife 12 to move downward and cut the alloy resistor. During the cutting process of the alloy resistor, the operator does not need to hold it by hand, and the operator stays away from the cutting position to avoid damage to the operator.

[0023] The utility model drives a screw rod to rotate by a motor, and the screw rod drives a placement seat to move on a base. After the alloy resistor is placed on the placement seat, the motor moves the alloy resistor to the lower side of a cutting knife, and a hydraulic press pushes the cutting knife to cut the alloy resistor, so that an operator is away from the cutting position, reducing the labor intensity of the operator, and a plurality of alloy resistors can be cut at the same time, thereby improving production efficiency.

[0024] The clamping assembly includes a plurality of round rods 20 fixedly disposed on the upper side of the placement seat 13 and distributed symmetrically on the left and right sides. A lifting plate 21 is slidably mounted on the plurality of round rods 20. A semicircular groove 22 matching the placement groove 14 is formed on the lower side of the lifting plate 21. Long grooves 23 are formed on the opposite sides of the two side plates 19. Round blocks 24 matching the long grooves 23 are fixedly disposed on the left and right sides of the lifting plate 21.

[0025] When cutting the alloy resistor, the motor 17 drives the screw 16 to rotate, the screw 16 drives the placement seat 13 to move toward the rear side of the base 1, the placement seat 13 synchronously drives the round rod 20 to move, the round rod 20 drives the lifting plate 21 to move, and the lifting plate 21 moves toward the placement seat 13 along the long groove 23 during the movement toward the rear side of the base 1. After the placement seat 13 moves to the position, the lower side wall of the lifting plate 21 abuts against the upper side wall of the placement seat 13, and the semicircular groove 22 and the placement groove 18 abut against the side wall of the alloy resistor, clamping the alloy resistor to ensure the smooth progress of the cutting process;

[0026] After the alloy resistor is cut, the motor 17 drives the placement seat 13 to move toward the front side of the base 1 through the screw 16, and the placement seat 13 synchronously drives the lifting plate 21 to move toward the front side of the base 1 through the round rod 20, and the lifting plate 21 synchronously moves along the long groove 23 toward the upper side of the round rod 20, so that the lifting plate 21 is separated from the placement seat 13, which is convenient for the operator to remove the cut alloy resistor.

[0027] The telescopic member includes a square cavity 30 opened inside the placement seat 13, the placement groove 14 is provided with a square opening interconnected with the square cavity 30, a vertical rod 31 matching the square opening is fixedly provided at the lower side of the square cavity 30, a square tube 32 is slidably mounted on the upper side of the vertical rod 31, a spring 33 is fixedly provided between the lower side of the square tube 32 and the side wall of the square cavity 30, and a circular arc platform 34 matching the placement groove 14 is fixedly provided on the upper side of the square tube 32;

[0028] A square plate 35 is slidably mounted in the square cavity 30, and the square plate 35 is fixedly connected to the lower sides of the plurality of square tubes 32. The square plate 35 is provided with a plurality of square holes matching the vertical rods 31. The left and right sides of the placement seat 13 are provided with through grooves interconnected with the square cavity 30. The left and right sides of the square plate 35 are rotatably mounted with round shafts 36 matching with the through grooves. The left and right side walls of the two round shafts 36 are fixed with rotating blocks 37. The left and right side walls of the placement seat 13 are provided with arc grooves 38 interconnected with the through grooves. The opposite sides of the two rotating blocks 37 are fixed with arc blocks 39 matching with the arc grooves 38.

[0029] When the operator places the alloy resistor in the placement groove 18, the square cylinder 32 is completely located inside the square cavity 30, the arc table 34 is aligned with the placement groove 18, so that the spring 33 is compressed, and the rotating block 37 drives the arc block 39 to be located under the circular shaft 36, so that the arc block 39 is located under the arc groove 38, and the square plate 35 is limited to prevent the square plate 35 from moving to the upper side of the square cavity 30, so that the arc table 34 extends out of the placement groove 18, so that the alloy resistor is in a horizontal state, ensuring the smooth cutting of the alloy resistor;

[0030] After the alloy resistor is cut, after the placement seat 13 moves to the front side of the base 1, the operator directly rotates the rotating blocks 37 on both sides, and the rotating blocks 37 on both sides synchronously drive the two arc blocks 39 to rotate. After the two arc blocks 39 are separated from the two arc grooves 38, under the elastic action of the spring 33, the square tube 32 is pushed to move upward, driving the square plate 35 to move upward, so that the arc table 34 extends out of the square mouth, and the cut alloy resistor is lifted, which is convenient for the operator to take out the alloy resistor and makes the operator's operation more convenient.

[0031] A collecting box 40 is installed on the upper side of the base 1 to collect the cut alloy debris, thereby avoiding the splashing of alloy resistor debris during the cutting process.

[0032] Limiting blocks 41 are fixedly provided on the upper sides of the plurality of round rods 20 to limit the movement of the lifting plate 21 .

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
