Description
Technical field
The utility model relates to a kind of lathe, relates in particular to large-scale hydraulic pressure sawing machine.
Background technology
Large hydraulic cuts sawing machine and is mainly used in the cold saw ferrous and nonferrous metals, on sawing machine, can expect and other shaped steel by the sawing circle, comprises the pipe of different wall.At present, the sawing process of cutting sawing machine has realized automation, but feeding also needs operation manually with clamping; Charging, clamping mode commonly used now are: cut the sawing machine middle part at hydraulic pressure and be provided with a clamping device; Clamping device unclamps during charging, the manual operating position that promotes saw spare to be cut, moves to the part arrival saw blade of its front end, clamping device clamping work pieces then; After workpiece clamps; The operating circuit that cuts saw blade is communicated with, begins to cut the saw workpiece automatically, cuts and unclamps clamping device again after saw is accomplished, manually travelling workpiece charging, circulation so repeatedly.One section of every sawing just needs artificial blowing, clamping work pieces, the special messenger need be set look after; Under plant personnel configuration condition of limited; The personnel of processing parts are just not enough on follow-up worker is continuous, can influence the deadline of overall operation so undoubtedly, can influence operating efficiency greatly.
Summary of the invention
The utility model purpose is to provide a kind of large hydraulic sawing machine with automatic feeding function.
The utility model is realized through following technical scheme:
A kind of large hydraulic sawing machine; It is made up of frame, power set, pay-off, clamping device and topping machanism; Frame is provided with the clamping device that clamps saw spare to be cut, and a side of clamping device is a feed end, and the frame of the opposite side of clamping device is provided with cuts saw blade.Said device comprises an optoelectronic switch, and optoelectronic switch connects through signal transmission line Lu Yuyi relay, and relay is connected with a feeding motor with a hydraulic control one-way valve through control circuit; Hydraulic control one-way valve links to each other with clamping device; Feed end one side of clamping device is provided with the swivel feeding dish, and the swivel feeding dish is by the feeding motor-driven, and its outer circumference surface upper edge circumferentially has groove; Saw spare to be cut is placed in the groove; And the axis of saw spare to be cut is vertical with the center line of swivel feeding dish, and said optoelectronic switch is made up of transmitter and receiver, and transmitter emission light is blocked or position of reflecting and the distance of cutting between the saw point are to cut the processing length of sawing part.Said optoelectronic switch is light-transmission type optoelectronic switch or reflection-type optoelectronic switch.
The utility model improvement cost is low, and configuration is simple, cuts saw and adds and can accomplish feeding automatically man-hour, clamp, cut the saw action, and can add up the quantity of cutting the saw part automatically, need not the special messenger and looks after, improved operating efficiency, shortened whole process time.
Description of drawings
Connection sketch map when Fig. 1 works for the utility model automatic feeding
Among Fig. 1: 1 is saw workpiece to be cut, and 2 is clamping device, and 3 for cutting saw blade, and 4 are the swivel feeding dish, and 8 is optoelectronic switch, and 9 is electronic counter, and 10 is relay, and 11 is hydraulic control one-way valve, and 12 are the feeding motor.
The specific embodiment
As shown in Figure 1, a kind of large hydraulic sawing machine of the utility model, it is made up of frame, power set, pay-off, clamping device and topping machanism; Frame is provided with the clamping device 2 that clamps saw spare to be cut; One side of clamping device 2 is a feed end, and the frame of the opposite side of clamping device 2 is provided with cuts saw blade 3, and said clamping device 2 comprises optoelectronic switch 8; Optoelectronic switch 8 connects through a signal transmission line Lu Yuyi relay 10; Relay is connected with a feeding motor 12 with a hydraulic control one-way valve 11 through control circuit, and hydraulic control one-way valve 11 links to each other with clamping device 2, and feed end one side of clamping device 2 is provided with swivel feeding dish 4; Swivel feeding dish 4 is driven by feeding motor 12; Its outer circumference surface upper edge circumferentially has groove, and saw spare to be cut is placed in the groove, and the axis of saw spare to be cut is vertical with the center line of swivel feeding dish 4; It is characterized in that: said optoelectronic switch 8 is made up of transmitter and receiver, and transmitter emission light is blocked or position of reflecting and the distance of cutting between the saw point are to cut the processing length of sawing part.If this operating position is constant, the saw part length of cutting that then processes is fixed, and further, the operating position of optoelectronic switch is made as adjustable, just can set the operating position of optoelectronic switch according to the length of every batch of blank needs flexibly.
The course of work of a kind of large hydraulic sawing machine of the utility model is following; As shown in Figure 1, at first be placed to saw workpiece 1 to be cut on the swivel feeding dish 4 that is positioned at clamping device 2 feed ends one side, start feeding motor 12; Feeding motor 12 drives 4 rotations of swivel feeding dish; Saw workpiece 1 to be cut is driven to cutting saw blade 3 directions and is advanced, and when the front end arrival Working position of saw workpiece 1 to be cut, promptly cuts the saw blade 3 corresponding distances of cutting between saw point and saw workpiece 1 front end to be cut and just in time reaches the length that saw is cut in requirement; This moment, the light positive that sends of luminous component of optoelectronic switch 8 was sheltered from by saw workpiece 1 front end to be cut well; The light accepting part of optoelectronic switch 8 divides because do not receive/receive the photo-signal that the luminous component of reflection sends, so its current signal to electronic counter 9 and relay 10 outputs all has a variation, at this moment:
1, electronic counter 9 is counted once automatically;
2, meanwhile, relay 10 passes through control circuit:
1. control 12 stalls of feeding motor, swivel feeding dish 4 stops feeding, saw workpiece 1 to be cut halts;
2. the piston of controlling hydraulic control one-way valve 11 moves, and promotes clamping device 2 and clamps saw workpiece 1 to be cut.
After clamping device 2 was in clamped position, the operating circuit that cuts saw blade 3 was in connected state, cut saw blade 3 automatic completion and cut the saw action.
After cutting saw action completion; Being cut that part of workpiece of sawing falls; This moment the light that sends of luminous component of optoelectronic switch 8 be not blocked, luminous component divides once more with light accepting part and connects, counter 9 resets, the piston of hydraulic control one-way valve 11 is oppositely mobile under the effect of relay 10, clamping device 2 unclamps; The motor of feeding simultaneously 12 starts once more, swivel feeding dish 4 continues feeding, circulation so repeatedly.
