Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate shearing machines, and particularly relates to a feeding auxiliary mechanism of a metal plate shearing machine. Background Art

[0002] Sheet metal shears are machines used to shear sheet metal. They use a moving upper blade and a fixed lower blade, with a reasonable blade gap, to apply shear force to metal sheets of various thicknesses, so that the sheets are broken and separated according to the required size. The working principle of the shear mainly includes the feeding, positioning and clamping of sheet metal materials, cutting operations, and material discharge.

[0003] The metal sheet is loaded by placing the blank plate flat on the belt, and after manual straightening, the motor drives the alloy roller to rotate the belt. The belt rotates forward to drive the blank plate close to the blade gap until the designated position is aligned with the blade gap, while the belt rotates in the reverse direction to drive the blank plate away from the blade gap, and the position of the blank plate can be adjusted horizontally.

[0004] During the feeding process of metal plates, the blank plate is placed flat on the belt. Manual straightening is time-consuming and laborious. Instead, two electric arms are used to push it from both sides to the middle. The blank plate will rub against the belt laterally. The blank plate is heavier than wooden boards, foam boards, etc., which will increase the wear on the upper surface during the belt feeding and straightening process of the blank plate. For this reason, we propose a feeding auxiliary mechanism for metal plate shearing machine. Utility Model Content

[0005] The purpose of the utility model is to provide a feeding auxiliary mechanism for a metal plate shearing machine, which can make the metal plate slide to the center and avoid friction with the rotating belt when adjusting the posture, so as to alleviate the wear on the upper surface of the rotating belt during feeding.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A feeding auxiliary mechanism for a metal plate shearing machine comprises a rotating belt, a supporting arm and a hydraulic cylinder are sequentially arranged below the rotating belt from top to bottom, the output end of the hydraulic cylinder extends upward and is fixedly connected to the lower surface of the supporting arm, the two ends of the supporting arm respectively extend obliquely upward to both sides of the rotating belt and are fixed with mounting plates, the upper surfaces of the two mounting plates are parallel to the upper surface of the rotating belt and are fixed with material carrying plates, and a plurality of steel balls are rotatably installed on the upper surfaces of the two material carrying plates. When feeding, the hydraulic cylinder is first controlled to lift the supporting arm, raise the mounting plate, the material carrying plate and the steel balls, so that the steel balls are higher than the rotating belt, and then The metal plate is placed flat on top of the steel ball, supported from both sides by two arms formed by the mounting plate and the loading plate, and then pushed toward the middle from both sides until the center of gravity of the metal plate is located in the middle of the two arms, and the front surface of the metal plate is parallel to the blade of the shearing machine, which can make the metal plate slide to the center and avoid friction with the rotating belt when adjusting the posture, so as to alleviate the wear on the upper surface of the rotating belt during feeding. After the metal plate is centered in place, the supporting arm is lowered until the steel ball is lower than the upper surface of the rotating belt, so that the metal plate falls on the rotating belt, which can control the rotating belt to rotate forward and move the metal plate forward to the specified position to reach the blade gap of the shearing machine.

[0008] It also includes two slide rails symmetrically arranged on both sides of the rotating belt. The two slide rails are parallel to the output end of the hydraulic cylinder and are slidably connected to the two sides of the support arm. When the two arms are raised or lowered, they slide along the slide rails. The slide rails are used to limit the support arm and can straighten the support arm.

[0009] Slip rings are fixed on both sides of the support arm, and the two slip rings are respectively slidably arranged outside the adjacent slide rails, thereby increasing the sliding contact surface between the two support arms and the two slide rails and improving the stability during the righting process.

[0010] Electric push rods are horizontally arranged at positions far away from each other outside the two loading plates, and the output ends of the two electric push rods are horizontally opposite to each other. The two electric push rods are controlled to approach each other, so as to push the metal plate on the steel ball to the center, and the two sides of the metal plate are parallel to the two sides of the rotating belt, so that the metal plate can be quickly centered. After being positioned, the two electric push rods are controlled to move away from each other.

[0011] Two parallel push plates are fixed to the output ends of the two electric push rods respectively. The height of the push plates is greater than the height of the steel balls, which increases the contact area of ​​the two electric push rods with the metal plate, and can push the metal plate to the center from a wider range to prevent the metal plate from tilting.

[0012] Elastic pads are fixed on the sides of the two push plates that are close to each other. Through the deformation of the elastic pads, a certain lateral margin is left to prevent the two electric push rods from excessively squeezing the metal plate, and to provide buffering when the push plates contact the metal plate to avoid hard collisions.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a feeding auxiliary mechanism for a metal plate shearing machine. When feeding, the hydraulic cylinder is first controlled to lift the supporting arm, and the mounting plate, the material carrying plate and the steel ball are raised, so that the steel ball is higher than the rotating belt, and then the metal plate is flatly placed above the steel ball, and two supporting arms are formed by the mounting plate and the material carrying plate to support from both sides, and then the metal plate is pushed toward the middle from both sides respectively, until the center of gravity of the metal plate is located in the middle of the two supporting arms, and the front surface of the metal plate is parallel to the blade of the shearing machine, so that the metal plate can be slid to the center, and the friction with the rotating belt when adjusting the posture is avoided, so as to alleviate the wear of the upper surface of the rotating belt during feeding.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-5As shown, a feeding auxiliary mechanism of a metal plate shearing machine comprises a rotating belt 1, and a Chinese utility model with a reference publication number of CN216096635U is a metal plate shearing machine. The rotating belt 1 can be rotatably installed on the feeding side of a shearing machine, and it can be driven by a motor to rotate forward or reverse. A supporting arm 2 and a hydraulic cylinder 3 are arranged from top to bottom below the rotating belt 1. The output end of the hydraulic cylinder 3 extends upward and is fixedly connected to the lower surface of the supporting arm 2. The two ends of the supporting arm 2 extend obliquely upward to both sides of the rotating belt 1 and are fixed with mounting plates 4. The upper surfaces of the two mounting plates 4 are parallel to the upper surface of the rotating belt 1 and are fixed with material carrying plates 5. A plurality of steel balls 6 are rotatably installed on the upper surfaces of the two material carrying plates 5. When feeding, the hydraulic cylinder 3 is first controlled to rotate upward. The pressure cylinder 3 lifts the supporting arm 2, raises the mounting plate 4, the loading plate 5 and the steel ball 6, so that the steel ball 6 is higher than the rotating belt 1, and then the metal plate is placed flat on the steel ball 6, and the mounting plate 4 and the loading plate 5 form two arms to support from both sides, and then the metal plate is pushed toward the middle from both sides until the center of gravity of the metal plate is located in the middle of the two arms, and the front surface of the metal plate is parallel to the blade of the shearing machine, so that the metal plate can slide to the center to avoid friction with the rotating belt 1 when adjusting the posture, so as to alleviate the wear on the upper surface of the rotating belt 1 during feeding. After the metal plate is centered in place, the supporting arm 2 is lowered until the steel ball 6 is lower than the upper surface of the rotating belt 1, so that the metal plate falls on the rotating belt 1, and the rotating belt 1 can be controlled to rotate forward, and the metal plate is moved forward to a specified position to reach the blade gap of the shearing machine.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, after the two carrier plates 5 are lowered, their edges close to each other are close to the two sides of the rotating belt 1, and the width of the mounting plate 4 is smaller than the width of the carrier plates 5, which can reduce the load of the two arms and reduce the output power required by the hydraulic cylinder 3. The two carrier plates 5 have a certain thickness and a structural strength sufficient to support the steel ball 6 and the metal plate. The two carrier plates 5 have a good levelness and will not cause the metal plate on the steel ball 6 to tilt, thereby preventing the metal plate from tilting and sliding off the steel ball 6.

[0025] like Figure 1 and Figure 2 As shown, it also includes two slide rails 7 symmetrically arranged on both sides of the rotating belt 1. The two slide rails 7 are parallel to the output end of the hydraulic cylinder 3 and are slidably connected to the two sides of the support arm 2. When the two arms are raised or lowered, they slide along the slide rails 7. The slide rails 7 are used to limit the support arm 2, so that the support arm 2 can be straightened.

[0026] like Figure 1 and Figure 2 As shown, slip rings 8 are fixed on both sides of the support arm 2, and the two slip rings 8 are respectively slidably arranged outside the adjacent slide rails 7 to increase the sliding contact surface between the two arms and the two slide rails 7 and improve the stability during the straightening process.

[0027] like Figure 1and Figure 5 As shown, electric push rods 9 are horizontally arranged at positions far away from each other outside the two loading plates 5. The two electric push rods 9 are connected to the central control computer signal of the shearing machine. The output ends of the two electric push rods 9 are horizontally opposite to each other. The electric push rods 9 can use SXTL model industrial electric telescopic rods, which can be fixed to the outside of the shearing machine by bolts. The two electric push rods 9 are controlled to approach each other, which can push the metal plate on the steel ball 6 to the center, and the two sides of the metal plate are parallel to the two sides of the rotating belt 1, which can be quickly centered. After landing, the two electric push rods 9 are controlled to move away from each other.

[0028] like Figure 1 and Figure 5 As shown, two parallel push plates 10 are fixed to the output ends of the two electric push rods 9 respectively. The height of the push plates 10 is greater than the height of the steel balls 6, which increases the area of ​​the two electric push rods 9 contacting the metal plate, and can push the metal plate to the center from a wider range to prevent the metal plate from tilting.

[0029] like Figure 1 and Figure 5 As shown, elastic pads 11 are fixed on the sides of the two push plates 10 that are close to each other. Through the deformation of the elastic pads 11, a certain lateral margin is left to prevent the two electric push rods 9 from excessively squeezing the metal plate, and to provide buffering when the push plates 10 contact the metal plate to avoid hard collisions.

[0030] The working principle of the utility model is: when loading materials, firstly control the hydraulic cylinder 3 to lift the supporting arm 2, raise the mounting plate 4, the material carrying plate 5 and the steel ball 6, so that the steel ball 6 is higher than the rotating belt 1, and then place the metal plate flat on the steel ball 6, and the mounting plate 4 and the material carrying plate 5 form two arms to support from both sides.

[0031] Then push the metal plate toward the middle from both sides until the center of gravity of the metal plate is located in the middle of the two arms and the front surface of the metal plate is parallel to the blade of the shearing machine, so that the metal plate can slide to the center and avoid friction with the rotating belt 1 when adjusting the posture, thereby alleviating the wear on the upper surface of the rotating belt 1 during feeding.

[0032] After the metal plate is centered in place, lower the support arm 2 until the steel ball 6 is lower than the upper surface of the rotating belt 1, so that the metal plate falls on the rotating belt 1, and the rotating belt 1 can be controlled to rotate forward, and the metal plate is moved forward to the specified position to reach the blade gap of the shearing machine.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
