Technical Field

The utility model relates to a hand die holder, specifically speaking relate to a hand die holder that sets up for installing the hand die on the film gloves production line.

Background

The hand die holder is an important component of a film glove production line, one end of the hand die holder is connected with a transmission chain, and the other end of the hand die holder is connected with a supporting hand die, so that the hand die holder is an indispensable combined connecting component on the production line. The hand die holder disclosed in patent No. 201820553167.4 has a structure that one end of a shaft rod is a prismatic section and extends out of a core hole of a connecting seat, and the other end of the shaft rod extends to a port of a shaft sleeve; the hand die pressing piece is detachably fixed on the connecting seat, a positioning hole matched with the prism section shape of the shaft rod is formed in the hand die pressing piece, a hand die clamping block is connected to the end, penetrating out of the positioning hole, of the shaft rod, a pin rod is arranged in the middle of the shaft rod, a spring is sleeved on the shaft rod between the pin rod and the hand die pressing piece, and the hand die clamping block is abutted against the hand die pressing piece through the spring to form the hand die pressing piece. The hand mould pressing piece is a piece body with symmetrical notches at the upper end and the lower end of the ellipse, a similar positioning hole with the same appearance as the piece body is arranged at the center of the piece body, and a connecting member consisting of supporting legs is respectively arranged at the junction of the long shaft and the short shaft of the ellipse corresponding to one side of the piece body. The connecting component has a relatively complex structure, not only brings trouble to processing, but also has long stroke when the hand die clamping block and the shaft rod integrally formed by the hand die clamping block are pushed forwards by power or return under the action of the spring due to the limitation of the structure when the hand die is to be disassembled and assembled on the hand die holder, so that the disassembling and assembling speed is slow and the whole working efficiency is influenced. At the same time, the fatigue strength of the spring is increased, and the service life is shortened. And the stability of the hand mold clamping clip is not ideal.

Disclosure of Invention

An object of the utility model is to provide a hand die holder, its simple structure, processing are convenient, and the stroke of hand die fixture block and axostylus axostyle is short fast during dismouting hand die, can obviously reduce spring fatigue strength and improve life, and the hand die clamping is stable, makes the problem that prior art deposited obtain solving.

The technical scheme of the utility model as follows: the hand die comprises a shaft sleeve, a connecting seat, a bearing, a chain pendant, a self-locking nut, a shaft rod, a hand die clamping block, a connecting bolt, a pin rod, a spring, a baffle and a bearing seat, wherein the shape of the connecting hole is matched with the shape of a connecting hole formed in the hand die, the thickness of the connecting hole is the same as the thickness of the periphery of the connecting hole, a central positioning hole is a limiting clamping block with an inner hexagonal through hole, the shaft rod part at the end of the hand die clamping block and a corresponding hole of the connecting seat are matched with the central positioning hole of the limiting clamping block, and a reinforcing pad is fixed at the position, corresponding.

The utility model discloses owing to taken the structure, especially the design of spacing fixture block, including the organic cooperation of other parts, not only simplified the component structure, strengthened location effect, reduced the axostylus axostyle stroke, improved hand former dismouting speed and production efficiency, alleviateed spring fatigue strength moreover, increased life and reduced the noise. The device also has the advantages of scientific and reasonable structural design, stable and reliable working performance, suitability for popularization and application in the industry and the like.

Detailed Description

Fig. 1-7 show a new product of a hand mold base of the present invention, which is designed based on the prior art. The one end fixed connection seat 2 at axle sleeve 1, the other end of axle sleeve 1 establishes to the reducing section the tip of reducing section is equipped with the external screw thread, connects chain pendant 4 through bearing 3, and 4 one ends of chain pendant are the bearing frame, and in the bearing frame was embedded to bearing 3, the reducing section of axle sleeve 1 was arranged in the inner circle of bearing 3. The end part of the reducing section penetrates through the inner ring of the bearing and then is connected with a self-locking nut 5. A shaft lever 6 is arranged in the shaft sleeve 1, the shaft lever 6 is also of a variable-diameter structure, the shaft lever part at the end of the hand mould clamping block 7 is of an outer hexagon, and the other end of the shaft lever part is of a cylinder shape; the hand mold clamping block 7 and the shaft lever 6 are welded into a whole; meanwhile, a limiting clamping block 8 is arranged at the center of the connecting seat 2, the limiting clamping block 8 is a connecting component, the shape of the connecting component is matched with the shape of a connecting hole arranged on the hand die, the thickness of the connecting component is the same as the thickness of the periphery of the connecting hole, a central positioning hole is an inner hexagonal through hole, and symmetrical connecting holes are arranged on two sides of the connecting component. A reinforcing pad 9 is fixed on the position of the outer part of the shaft sleeve in the gland of the connecting seat 2, which corresponds to the limiting clamping block 8; the limiting clamping block 8 is fixed with the connecting seat 2 and the reinforcing pad 9 into a whole through a bolt 10. And the shaft lever 6 fixed on the hand model clamping block 7 passes through the central positioning hole of the limiting clamping block 8 and the central corresponding hole of the connecting seat 2 to be arranged in the shaft sleeve 1. A pin rod 11 is arranged in the middle of the shaft rod 6, a spring 12 is sleeved outside a hexagonal shaft rod part between the pin rod 11 and the limiting fixture block 8, a limiting stop piece 13 is arranged at the tail end of the spring 12, and the hand mold fixture block 7 is abutted against the limiting fixture block 8 by the spring 12.

Use the utility model discloses when carrying out the dismouting to the hand former, through the terminal surface of drive arrangement control inserted bar roof pressure axostylus axostyle 6, make axostylus axostyle 6 remove in axle sleeve 1 inward facing left side direction, along with the propulsion of removal, hand former fixture block 7 breaks away from and outstanding spacing fixture block 8 and the quotation of connecting seat 2, and at this in-process spring 12 compresses, behind the joint hand former, the inserted bar is retreated, and spring 12 releases, and at this moment during hand former connecting hole is arranged in just to spacing fixture block 8, because its thickness with the same therefore spacing fixture block 8 of the peripheral thickness of connecting hole and hand former inside and outside wall parallel. The shaft lever 6 drives the hand model clamping block 7 to jack the limiting clamping block 8, so that the hand model is positioned. Due to the fact that the structure of the limiting fixture block 8 is adopted, the thickness of the limiting fixture block is the same as the thickness of the periphery of the hand die connecting hole, the stroke of the hand die fixture block 7 fixed on the shaft rod 6 can be effectively shortened in the hand die assembling and disassembling process, the fatigue strength of the spring is obviously reduced, the maintenance frequency is reduced, the service life is prolonged, and the work efficiency of hand die assembling and disassembling is improved.
