[0031] Please refer to Figures 1-7The utility model provides an elevator guide rail sawing length accurate and adjustable production line, comprising a cutting frame 1, a main material unloading frame 2 and a waste material unloading frame 3 which are arranged in sequence, and a transverse track 4 and a longitudinal track 5 which are staggered at the rear end of the cutting frame 1; a saw table 6 and a fixed length device 7 are arranged at intervals on the cutting frame 1, the main material unloading frame 2 moves on the transverse track 4 and unloads the cut elevator guide rail main material, and the waste material unloading frame 3 moves on the longitudinal track 5 and unloads the cut elevator guide rail waste.
[0032] The cutting frame 1 includes a horizontal frame and a first foot support 12 with adjustable height arranged at the bottom of the horizontal frame 11; rollers 13 are arranged on the horizontal frame 11 at equal intervals along the long direction, and a number of fixed-length screw holes 14 are horizontally penetrated on both sides of the horizontal frame 11, and the fixed-length screw holes 14 are used to install the fixed-length device 7; the first foot support 12 is used to adjust the overall height of the cutting frame 1. In actual working conditions, when it is necessary to cut elevator rail accessories of different thicknesses, the first foot support 12 can be used to adjust the overall height of the cutting frame 1 to adapt to the accessories to be cut, without having to frequently adjust the height of the saw blade on the saw table 6, thereby avoiding accidental wear of the saw blade caused by frequent height adjustment.
[0033] The main material unloading rack 2 and the waste material unloading rack 3 both include an upper rack 21 and a lower rack 22, and a second foot support 23 with adjustable height is arranged between the upper rack 21 and the lower rack 22. The height of the main material unloading rack 2 and the waste material unloading rack 3 can be adjusted by the second foot support 23 respectively, so as to adapt to the height of the cutting rack 1; the bottom of the lower rack 22 of the main material unloading rack 2 and the waste material unloading rack 3 is provided with self-locking running wheels, so that the main material unloading rack 2 can run on the transverse track 4, and the waste material unloading rack 3 can run on the longitudinal track 5. The upper rack 21 of the main material unloading rack 2 and the waste material unloading rack 3 is provided with a roller 13.
[0034] The transverse rail 4 is arranged at 90 degrees with the cutting frame 1 in the horizontal direction.
[0035] The longitudinal track 5 is arranged in a straight line with the cutting frame 1 in the horizontal direction and intersects with the transverse track at 490 degrees.
[0036] The sawing table 6 is horizontally mounted on the rear half of the cutting frame 1 .
[0037] The length-fixing device 7 is detachably assembled and is installed on the cutting frame 1 at an angle in the horizontal direction. The length-fixing device 7 includes a rotating plate 71 and a pair of positioning bolts 72 rotatably inserted at both ends of the rotating plate 71; the rotating plate 71 is connected to a positioning rod 73 through a connecting rod, and the bottom of the rotating plate 71 is connected to the cutting frame 1 through a reset spring 74. The reset spring 74 and the positioning rod 73 are respectively located on the front and rear sides of the rotating plate 71, and assembly shaft holes are symmetrically arranged at both ends of the rotating plate 71, and the positioning bolts 72 are rotatably inserted in the assembly shaft holes.
[0038] In this case, an elevator guide rail sawing line with precisely adjustable cutting length has the following working process in actual working conditions:
[0039] 1. Cut to length:
[0040] When it is necessary to cut a certain length of elevator guide rail, first determine the length between the saw blade and the positioning rod 73 on the cutting frame 1, find the corresponding fixed-length screw hole 14 on the cutting frame 1, and then pass a pair of positioning bolts 72 through the fixed-length screw hole 14 and insert them into the assembly shaft holes at both ends of the rotating plate 71, so that the rotating plate 71 is rotatably installed on the cutting frame 1, so that the fixed-length device 7 is assembled. At this time, the length between the saw blade and the positioning rod 73 is the length of the main material of the elevator guide rail.
[0041] When the roller 13 on the cutting frame 1 drives the elevator guide rail toward the saw blade, the weight of the elevator guide rail overcomes the elastic force of the reset spring 74 on the fixed length device 7, and the elevator guide rail will press down the positioning rod 73 that is higher than the cutting frame 1, and the positioning rod 73 will not hinder the elevator guide rail from moving forward.
[0042] When the elevator guide rail moves forward to the cutting position, the elevator guide rail is separated from the positioning rod 73. Under the action of the reset spring 74, the positioning rod 73 is reset to a position higher than the cutting frame 1 and supports the end of the elevator guide rail. Then the saw blade cuts the elevator guide rail. The cut front section of the elevator guide rail is waste, and the rear section of the elevator guide rail is the main material.
[0043] 2. Classification and transportation:
[0044] After the cutting is completed, the elevator guide rail waste and the elevator guide rail main material continue to move forward on the cutting frame 1. When the elevator guide rail waste moves forward to the waste unloading rack 3, the elevator guide rail waste can be transferred linearly to the waste placement area through the waste unloading rack 3 on the longitudinal slide rail. When the elevator guide rail main material moves forward to the main material unloading rack 2, the elevator guide rail waste can be transferred horizontally to the main material placement area through the main material unloading rack 2 on the transverse slide rail.
[0045] Compared with the prior art, the present invention provides an elevator guide rail sawing length-precisely adjustable production line, which precisely adjusts the length of the elevator guide rail to be cut by setting a fixed-length device on the cutting frame, thereby effectively solving the inefficient problem of length determination by manual ruler and effectively improving production efficiency.
[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
