Description

A kind of rotary-type hot upsetting die holder

Technical field

The utility model relates to mould pull bar technical field of processing equipment, is a kind of rotary-type hot upsetting die holder specifically.

Background technology

The title that mould have " mother of industry ".Mould be exactly in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.But the part requirements of mould to formation mould is all very strict, and the error on mould will be directly passed to shaping part, therefore ensure that the precision of mould parts is most important.

Pull bar is used to pull open stripper plate, there is certain positioning action simultaneously, use very frequent in a mold, the end of pull bar adopts hot forging process to be pressed into, when suppressing, prior art is that artificial being put into by the raw material of pull bar is done on the hot upsetting die holder of circular-rotation in the horizontal plane, after hot upsetting, treat that hot upsetting die holder goes to front, operating position, take out by hand again, because the pull bar temperature after hot upsetting is high, easy injury operator, and pull bar temperature during hot upsetting is high, very easily gluing under oil cylinder high pressure is pressed in bottom hot upsetting die holder, if take out not in time, manufacturing schedule will be affected, be unfavorable for production safety, and this for manual take out operation more difficult.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of rotary-type hot upsetting die holder.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of rotary-type hot upsetting die holder, comprise U-shaped bracing frame, described U-shaped bracing frame upper end is provided with rotating shaft, the middle part of described rotating shaft is evenly distributed with the hot upsetting die holder of four adjacent spaces 90 °, be equipped with in the middle part of described hot upsetting die holder and insert material hole, all be fixed with along inserting the axial stage clip arranged in material hole bottom described slotting material hole, the part that described rotating shaft rear and front end is stuck in U-shaped bracing frame is quadrangular, four sides of described quadrangular are equipped with into round belting, and four lateral edges of quadrangular are equipped with the fillet down to becoming round belting place;

Described one-tenth round belting includes the rectangular channel be arranged on quadrangular, all spring is installed in described rectangular channel, rectangular channel top is equipped with the arc covers be stuck in corresponding rectangular channel, described arc covers all can move up and down in rectangular channel, and arc covers can not be deviate from, the inner face of arc covers is all fixed on corresponding spring.

The curvature of described arc covers is identical with the curvature of fillet on quadrangular.

The beneficial effects of the utility model are: the utility model adopts the rotary-type hot upsetting die holder at vertical rotation in surface, pull bar gravitate after hot upsetting falls automatically, the elastic force of stage clip contributes to reducing pull bar and glues the phenomenon being pressed in and inserting bottom material hole, auxiliary connecting rod ejects, the process that after decreasing the hot upsetting of pull bar, operating personnel are taken out, avoids the injury of pull bar to operating personnel, decreases operator's operating procedure, improve operating efficiency, alleviate operator's labour intensity.

The support end of quadrangular shape with carry out face between U-shaped bracing frame and contact, supporting & stablizing, when rotating, become the arc covers in round belting protruding, thus effectively auxiliary rotating shaft keeps smooth and easy when rotating, and reduces axis of rotation concussion.

Detailed description of the invention

The technological means realized to make the utility model and creation characteristic are easy to understand, and set forth further below to the utility model.

As shown in Figures 1 to 6, a kind of rotary-type hot upsetting die holder, comprise U-shaped bracing frame 1, described U-shaped bracing frame 1 upper end is provided with rotating shaft 2, the middle part of described rotating shaft 2 is evenly distributed with the hot upsetting die holder 3 of four adjacent spaces 90 °, be equipped with in the middle part of described hot upsetting die holder 3 and insert material hole 4, all be fixed with along inserting the axial stage clip 5a arranged in material hole 4 bottom described slotting material hole 4, the part that described rotating shaft 2 rear and front end is stuck in U-shaped bracing frame 1 is quadrangular 6, four sides of described quadrangular 6 are equipped with into round belting 7, four lateral edges of quadrangular 6 are equipped with the fillet 8 down to becoming round belting 7 place.

Described one-tenth round belting 7 includes the rectangular channel 9 be arranged on quadrangular 6, in described rectangular channel 9, spring 5b is all installed, rectangular channel 9 top is equipped with the arc covers 10 be stuck in corresponding rectangular channel 9, described arc covers 10 all can move up and down in rectangular channel 9, and arc covers 10 can not be deviate from, the inner face of arc covers 10 is all fixed on corresponding spring 5b, and the curvature of arc covers 10 is identical with the curvature of fillet 8 on quadrangular 6.

During use, the bar making pull bar is put into the hot upsetting die holder that upwards rotates from side, when going to vertical state, external oil cylinder presses down, by inserting the bar jumping-up in material hole, after oil cylinder removes, under stage clip effect, pull bar pops up, depart from bottom surface, slotting material hole, hot upsetting die holder is rotated further, and goes to bottom in process, gravitate, pull bar is deviate from hot upsetting die holder.

In axis of rotation process, when external oil cylinder press down carry out hot upsetting time, a side of quadrangular is just in time in and U-shaped bracing frame base plane surface contact state, therefore support during hot upsetting steadily, oil cylinder working-pressure removes, arc covers in press-in U-type groove ejects by spring, and arc covers and fillet form approximate circle jointly, smooth and easy to ensure axis of rotation process.

More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
