Abstract

The utility model provides a punching device of a tubular structural part. The problems that burrs on the surface and the inner wall of the tubular structural part are numerous, machining efficiency is low and cost is high existing in a tubular structural part hole machining method in the prior art are solved. The punching device of the tubular structural part comprises a female die fixing seat, a columnar female die, a clamping ring, a clamping ring seat, positioning blocks and a positioning rocking handle. The female die fixing seat is fixedly arranged on a base on one side of a punch. The columnar female die is fixedly arranged on the female die fixing seat. The clamping ring seat is arranged at the symmetrical position of the female die fixing seat, and the clamping ring is sleeved inside the clamping ring seat. A left positioning block and a right positioning block are symmetrically arranged on the end face of the clamping ring seat. The positioning rocking handle is arranged on the end face of the clamping ring, and when the positioning rocking handle is respectively located on the left positioning block and the right positioning block, the clamping ring just rotates by 180 degrees. A through hole is arranged in the columnar female die in the radial direction, the bore diameter of the through hole is matched with the size of a hole to be punched, and the axis of the through hole and the axis of the punch are in coincidence. The punching device of the tubular structural part has the advantages of being simple in structure, free of burrs after punching, and capable of improving production rate and machining precision.

Description

A kind of tubular structural member hole punched device

Technical field

The utility model relates to a kind of hole punched device, specially refers to a kind of tubular structural member hole punched device.

Background technology

Prior art is carried out radial direction through hole to tubular structural member and is added the method that adopts hole milling, boring man-hour usually, because the processing of hole milling, boring is consuming time longer, drill bit consumption is serious, to difficult accurately location, hole, and, the tubular structural member surface that processes and the burr of inwall are more, need to adopt emery wheel that burr is cleared up, and the cleaning of burr are cumbersome, the burr of tubular structural member inwall particularly, be not easy to remove, therefore, working (machining) efficiency is low, cost is high.Obviously, it is many that prior art tubular structural member hole forming method exists tubular structural member burr surperficial and inwall, and working (machining) efficiency is low, problems such as cost height.

The utility model content

Many for the tubular structural member that solves the existence of prior art tubular structural member hole forming method burr surperficial and inwall, working (machining) efficiency is low, problems such as cost height.The utility model proposes a kind of tubular structural member hole punched device.

A kind of tubular structural member hole punched device, it is characterized in that: this device comprises die holder, column die, collar, collar seat, locating piece and location rocking handle, be fixed with the die holder on the base of drift one side, the column die is fixed on the die holder; The collar seat is arranged on the symmetric position of die holder, is set with collar in the collar seat; Left and right locating piece is symmetricly set on collar seat end face, and the location rocking handle is arranged on the collar end face, and when the location rocking handle was in left and right locating piece respectively, collar is the Rotate 180 degree just; The column die radially be provided with through hole, the aperture with treat that the size of punching is complementary, the axis of its through hole and the axis of drift coincide.

Further, described die holder adopts bolt to be connected with base with the collar seat.

The useful technique effect of the utility model tubular structural member hole punched device is simple in structure, does not have burr after the punching, has improved productivity ratio and machining accuracy.

Description of drawings

Accompanying drawing 1 is the utility model tubular structural member hole punched device front view;

Accompanying drawing 2 is the utility model tubular structural member hole punched device left view.

Below in conjunction with the drawings and specific embodiments the utility model tubular structural member hole punched device is further described.

The specific embodiment

Accompanying drawing 1 is the utility model tubular structural member hole punched device front view, and accompanying drawing 2 is the utility model tubular structural member hole punched device left view.Among the figure, 1 is the die holder, and 2 is the column die, and 3 is drift, and 4 is die shank, and 5 is the collar seat, and 6 is collar, and 7 is tubular structural member, and 8 are the location rocking handle, and 9 is right locating piece, and 10 is through hole, and 11 is base, and 12 is left locating piece.As seen from the figure, a kind of tubular structural member hole punched device, this device comprises die holder 1, column die 2, collar 6, collar seat 5, locating piece 9, locating piece 12 and location rocking handle 8, be fixed with die holder 1 on the base 11 of drift 3 one sides, column die 2 is fixed on the die holder 1; Collar seat 5 is arranged on the symmetric position of die holder 1, is set with collar 6 in the collar seat 5; Right locating piece 9 and left locating piece 12 are symmetricly set on collar seat 5 end faces, and location rocking handle 8 is arranged on collar 6 end faces, and when location rocking handle 8 was in left and right locating piece respectively, collar 6 is the Rotate 180 degree just; Column die 1 radially be provided with through hole 10, the aperture with treat that the size of punching is complementary, the axis of the axis of its through hole 10 and drift 3 coincides.Die holder 1 adopts bolt to be connected with base 11 with collar seat 5.Reality to the tubular structural member punch process in, tubular structural member 7 after being shaped is packed in the collar 6, tubular structural member 7 is fixed on the collar seat 5 by collar 6, the front portion of tubular structural member 7 is sleeved on the column die 2, make its end face draw close die holder 1, at this moment, through hole 10 axis and drift 3 axis on the column die 2 coincide, for tubular structural member 7 to be processed provides location and machining benchmark.Location rocking handle 8 on the collar 6 is fixed near right locating piece 9, carries out punching with 3 pairs of tubular structural members of the drift under the punch press die shank 47.Since column die 2 radially be provided with through hole 10, the aperture with treat that the size of punching is complementary, the axis of the axis of its through hole 10 and drift 3 coincides, so punching accurately.As intact first Kong Chenghou of punching, rotation location rocking handle 8 makes its location rocking handle 8 Rotate 180 degree near left locating piece 12, is about to tubular structural member Rotate 180 degree, dashes second hole again, thus, goes out the through hole of two 180 degree symmetries.After punching is finished, unload tubular structural member, and then can carry out punching another tubular structural member, therefore, the punching of the utility model tubular structural member hole punched device is quick and convenient.

The useful technique effect of the utility model tubular structural member hole punched device is simple in structure, does not have burr after the punching, has improved productivity ratio and machining accuracy.
